Impact of Sociocultural Norms on Career Progression of Female Dentists: A Cross-Sectional Study from Khyber Pakhtunkhwa, Pakistan
type: item
description: Background: Female dentists face multiple challenges that may hinder their career progression, including sociocultural norms, family responsibilities, and workplace barriers. This study aimed to explore the perceptions of female dentists in Khyber Pakhtunkhwa, Pakistan, regarding factors influencing their professional advancement. Methodology: A cross-sectional survey was conducted among 213 female dentists working in both public and private dental sectors across Hayatabad, Peshawar City, Abbottabad, and Swat. A structured, validated questionnaire assessed sociodemographic characteristics, professional practice, and perceived barriers categorized into family, interpersonal, environmental, and sociocultural domains. Data were analyzed using descriptive statistics and logistic regression to examine associations between these barriers and promotion status. Results: Most participants were aged 30–39 years (53.5%), married (76.1%), and specialists (65.7%), with the majority practicing full-time (93%). Family-related challenges were the most reported barriers, with 47.9% strongly agreeing that family responsibilities and 49.2% that balancing work and family affected their careers; 59.2% identified childcare responsibilities as a significant challenge. Interpersonal barriers included male dominance (26.8%) and gender discrimination (20.2%), while environmental challenges were most notable in safe transportation (41.3%) and driving restrictions (39.9%). Sociocultural barriers were also prominent, particularly societal beliefs assigning primary child-rearing responsibilities to women (73.2% strongly agree/agree) and the lack of family-friendly policies (58.2%). Logistic regression indicated that family and sociocultural challenges were significantly associated with lower promotion rates. Conclusions: Female dentists in Khyber Pakhtunkhwa face multifaceted barriers to career progression, driven largely by family, sociocultural, and environmental factors. Addressing these chal…

Comparative Study of Cardiovascular Risk and Metabolic Syndrome in male and female patients with Rheumatoid Arthritis
type: item
description: Rheumatoid arthritis (RA) is associated with an increased burden of cardiovascular disease (CVD) and metabolic syndrome (MetS), though sex-specific patterns remain underexplored. This cross-sectional study aimed to compare the prevalence of MetS and estimate the 10-year cardiovascular risk between male and female RA patients. A total of 300 RA patients (150 males, 150 females) were evaluated using harmonized MetS criteria and the SCORE-2 algorithm. Results showed that MetS was significantly more prevalent in females (56.0% vs. 36.7%, p < 0.001), characterized by higher rates of central obesity and low HDL-cholesterol. In contrast, males exhibited higher 10-year cardiovascular risk (7.4% vs. 5.1%, p < 0.001). However, the presence of MetS disproportionately elevated cardiovascular risk in females, nearly equalizing risk between sexes in the MetS subgroup. Multivariate analysis confirmed MetS as a stronger predictor of high cardiovascular risk in women. These findings highlight significant sex-based disparities in metabolic and cardiovascular profiles in RA, underscoring the need for sex-stratified risk assessment and targeted management strategies to mitigate cardiovascular morbidity.

Comprehensive Review of Conjunctivitis: Etiology, Diagnosis, Clinical Differentiation, and Evidence-Based Management
type: item
description: One of the most common eye diseases observed in primary care and ophthalmology is conjunctivitis, which accounts for more than 1% of all primary care visits and places a significant financial strain on the healthcare system. To distinguish it from other potentially vision-threatening causes of red eye, a comprehensive clinical assessment is required due to its many etiologies, which include viral, bacterial, allergic, toxic and systematic disease-associated types. The current research on conjunctivitis’ epidemiology, risk factors, clinical manifestation, diagnostic techniques, and treatment compiles in this review. Given the clinical overlap and frequent misinterpretation, special attention is paid to differentiating infectious from non-infectious forms and viral from bacterial etiologies. The limits of laboratory diagnostics advancements, especially PCR and fast antigen detection, are examined. Conjunctivitis associated with severe mucocutaneous conditions such Stevens-Jhonson syndrome, reactive arthritis, rosacea, and graft-versus-host disease are also discussed in the review. Evidence-based recommendations and possible risks are taken into consideration when evaluating current treatment options, including the function of antibiotics, antivirals, corticosteroids, immunomodulators, and supportive medicines. Reducing needless antibiotic usage, avoiding problems, and enhancing patient outcomes all depend on an understanding of the various presentations and suitable management techniques.

High Prevalence of Iron Deficiency Anaemia Among Pregnant Women in District Peshawar: A Cross-Sectional Study
type: item
description: Anaemia among pregnant women remains a pressing public health concern, especially in tropical developing nations. Having too few healthy red blood cells can cause extreme fatigue, weakness, and shortness of breath for expectant mothers. This study aimed to determine the prevalence of and risk factors associated with iron-deficiency anaemia amidst expectant mothers in Peshawar District, Pakistan. A cross-sectional research design was employed, selecting 100 pregnant patients from Shah Medical Center in Peshawar using proportional-to-size sampling. Clinicians drew 4 ml of venous blood from participants to clinically assess anaemic status. The investigators aimed to elucidate the prevalence of deficient iron levels among local mothers-to-be and identify potential predisposing factors through statistical analysis of the collected medical data. Among 100 samples, 25 showed to be anaemic and the parameters were counted lower than normal. As per the World Health Organization, the criteria for anaemia in pregnancy were applied and serum ferritin < 20µg/l was the cut-off point for iron deficiency. Data regarding risk factors was gathered using pre-designed questionnaires. The prevalence of iron-deficiency anaemia in pregnant women was 22% while most of the cases of anaemia were mild. In this research, the risk factors accompanying anaemia included the period of gestation, poor advice, iron pills intake during antenatal, socioeconomic status, and poor hygiene condition. This study concludes that the high prevalence of iron-deficiency anaemia among pregnant women can be averted if the prevention includes giving iron supplements, proper diagnosis of gestation, and health education

In Silico Design of a Multi-Epitope Vaccine Candidate Against Lassa Virus Using Immunoinformatics and Molecular Modeling Approaches
type: item
description: Lassa hemorrhagic fever is a viral acute zoonotic disease caused by Lassa mammarenavirus (LASMV) that is part of the Arenaviridae family. With rising global infection and mortality, developing an effective LV vaccine remains an urgent worldwide necessity. In this research, utilizing immunoinformatics methods, we developed a multi-epitope vaccine for the prevention and treatment of LV. Experimentally determined epitopes of the LV were retrieved from ViPR and IEDB databases and subsequently analyzed for various immunological and physiochemical properties. The finalized 12 epitopes were used for vaccine constructions [(LV-1 (300 aa) and LV-2 (353 aa)] with the help of adjuvant (beta-defensin-1 and ribosomal protein) linked to the N-terminal by an EAAK linker. To make the immunogenicity better of the vaccine, a pan-HLA DR binding epitope (13aa) was also introduced and selected epitopes were separated with GPGPG linkers. Predicted vaccine constructs were safe, antigenic, and stable with modeled secondary and 3D structures against LV. The complex between the final vaccine and immune receptors (RIG-I) was evaluated by molecular docking and showed a favorable interaction pattern, including hydrogen bonding and high binding affinity of -10.99 (LV-1) and -29.22 (LV-2) kcal/mol. Codon optimization and in-silico cloning verified the suggested vaccines’ effective expression in E.Coli. Finally, in-silico immune simulation demonstrated that LV-1 and LV-2 would also strongly stimulate the immune system against LV. The final vaccines need experimental confirmation of their safety and efficiency in the control of LV infections.

REVIEW: CRISPR-Cas Methodologies in the Detection and Treatment of Infectious Illnesses
type: item
description: The identification of Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) and their corresponding Cas proteins, originally a bacterial defense mechanism, has initiated a transformative phase in genetic engineering with significant ramifications for clinical treatment. This review examines the swift advancement and many uses of CRISPR-Cas techniques in the identification and management of infectious diseases, emphasizing their capacity to revolutionize contemporary clinical practice. In diagnostics, systems such as SHERLOCK (for RNA) and DETECTR (for DNA) employ the collateral cleavage activity of Cas nucleases (e.g., Cas12 and Cas13) to enable ultra-sensitive, isothermal, and quick detection of viral and bacterial nucleic acids, including SARS-CoV-2. These field-deployable devices, in conjunction with Next Generation Sequencing augmentation methodologies such as DASH and FLASH for low-frequency targets, signify a substantial advancement beyond conventional diagnostic techniques. Therapeutically CRISPR-Cas provides a means to achieve a functional cure for chronic and latent viral infections by accurately targeting and modifying integrated viral genomes that are typically unreachable by standard antivirals. Promising pre-clinical research has shown the eradication or inactivation of viruses such as Human Immunodeficiency Virus-1 (HIV-1) and Hepatitis B Virus (HBV) through tactics like multiplexed guided RNAs and less-mutagenic base editors. Although the remarkable promise is evident, issues of delivery efficiency, off target editing, and host immunity must be resolved as these technologies go into preliminary clinical trials. Ultimately, CRISPR-Cas techniques represent a disruptive force, offering accurate, diverse, and readily changeable tools that are set to become essential in the clinical management of infectious diseases.

Gene-Targeted Antimicrobial Strategies Using CRISPR-Cas Systems Against Multidrug-Resistant Bacterial Pathogens
type: item
description: The rapid emergence of antibiotic-resistant bacteria has significantly outpaced the development of new antimicrobial agents, posing a global health threat. This review investigates the application of CRISPR-Cas9 and CRISPR-dCas9 systems as innovative strategies to combat resistance in key bacterial pathogens. A systematic literature search identified studies focused on methicillin-resistant Staphylococcus aureus (MRSA) and extended-spectrum β-lactamase (ESBL)-producing Escherichia coli. In MRSA, the CRISPR-dCas9 system was used to suppress mecA gene transcription, leading to a 77% reduction in gene expression without compromising bacterial viability-an approach with implications for microbiome-safe interventions. In contrast, CRISPR-Cas9 targeting of conserved ESBL gene sequences in E. coli successfully cleaved resistance determinants, resulting in >99% re-sensitization to β-lactam antibiotics. The engineered pRESAFRESBL plasmid demonstrated cross-sensitivity restoration, suggesting plasmid-wide disruption of co-transferred resistance genes. Together, these findings highlight the transformative potential of CRISPR-based technologies in reversing resistance phenotypes through precise, gene-targeted interventions. This approach paves the way for next-generation antimicrobial therapies that either neutralize resistance while preserving beneficial flora or directly eradicate resistant clone

Comparative In Silico Analysis of Wild-Type and Mutant-Type Akt2 Gene Mutation (C.58c>T) In Type-2 Diabetes Mellitus
type: item
description: Type 2 Diabetes Mellitus (T2DM) is a complex and chronic metabolic disorder that has been frequently linked to single nucleotide polymorphisms (SNPs) in the AKT2 gene. AKT2, a key isoform of the AKT kinase family, plays an essential role in metabolic regulation and has been implicated in the development and progression of several cancers, including ovarian, breast, and pancreatic malignancies. Genetic mutations in AKT2 often lead to impaired insulin signaling and secretion, positioning this gene as a crucial therapeutic target for both metabolic and oncogenic pathologies. In the present study, a computational analysis was undertaken to examine the structural and functional consequences of a specific point mutation in the AKT2 protein. Bioinformatics tools predicted the mutation to be pathogenic, resulting in notable destabilization of the protein’s native conformation. To further explore therapeutic interventions, molecular docking simulations were performed with two candidate ligands, MESOBILIVERDIN and MK-2206, against the mutant AKT2 protein. MESOBILIVERDIN exhibited superior binding affinity and enhanced structural stability, with a calculated binding energy of −13.02 kcal/mol, compared to MK-2206, which showed a binding energy of −10.5 kcal/mol. These findings suggest both compounds possess therapeutic potential; however, MESOBILIVERDIN appears to be the more promising ligand for mutation-specific targeting in T2DM.Collectively, this study offers a computational framework for assessing mutation-induced alterations in protein behavior and supports the application of structure-based drug design approaches in the development of targeted therapies for genetically defined subtypes of metabolic disorders.

Computational Analysis of GRIN2A C1448R Variant in Epilepsy-Associated Intellectual Disability and their Structural Impact on NMDA Receptor Binding with Rapastinel and Dizocilpine
type: item
description: Epilepsy-associated intellectual disability (ID) encompasses a spectrum of neurodevelopmental disorders often caused by genetic mutations affecting synaptic transmission. This study employed a dry-lab, in silico approach to identify and characterize high-confidence candidate genes implicated in epilepsy-related ID, with a focus on GRIN2A, a subunit of the N-Methyl-D-Aspartate (NMDA) receptor complex. The pathogenic variant, c.4342T>C (p.Cys1448Arg), was subjected to computational analysis, including pathogenicity prediction, protein stability evaluation, and molecular docking. Two ligands, Rapastinel (GLYX-13) and Dizocilpine (MK-801) were selected for docking based on their clinical and pharmacological relevance to NMDA receptor modulation. Comparative docking revealed a reduction in binding affinity for Rapastinel (from −7.5 to −7.1 kcal/mol) and a slight increase for Dizocilpine (from −8.3 to −8.4 kcal/mol) in the mutant receptor. Protein–ligand interaction profiling showed that Rapastinel’s hydrogen bonding network was disrupted, while Dizocilpine retained hydrophobic interactions. Normal mode analysis indicated increased structural flexibility, with lower eigenvalues and elevated B-factors in the mutant complex, suggesting destabilized receptor conformation. These findings provide molecular insight into how the C1448R mutation may contribute to synaptic dysfunction in epilepsy-associated intellectual disability. This study underscores the utility of computational biology in exploring genotype–phenotype relationships and may guide future drug development efforts targeting GRIN2A related epileptic disorders.

Computational Drug Repurposing for The Management of Pathogenicity of Beta-Thalassemia
type: item
description: Beta-Thalassemia is an inherited disorder caused by mutation in the HBB gene, resulting in the abnormal synthesis of beta globin protein. The c.92G>C (p.Arg31Thr) mutation of HBB gene is prevalent in South Asian population and results unstable protein. The current study uses computational approaches to analyze the pathogenicity of this mutation and the ability of three ligands, 4-Phenylbutyric Acid (4-PBA), Voxelotor, and Heminin stabilizing mutant beta-globin protein. Bioinformatics tools (MutationTaster, SIFT, PolyPhen-2, FATHMM) confirmed that the mutation is deleterious and impact the function of protein. I-Mutant and Mu-Pro suggested that the stability of protein decreases due to p.Arg31Thr mutation. Molecular docking was carried out using AutoDock Vina revealed that 4-PBA and Hemin show stronger binding affinity towards the mutant protein (−6.5 kcal/mol and −6.8 kcal/mol, respectively) as compared to wild-type protein, suggesting a stabilizing effect. Post-dock analysis employing Protein-Ligand Interaction Profiler (PLIP) showed that enhanced hydrophobic interactions and hydrogen bonding were observed in mutant-ligand complexes. In contrast, Voxelotor represented a reduction in the binding affinity to mutants, indicating that conformational changes have affected the binding. These findings indicate that 4-PBA and Hemin can be potentially used to reduce the severity of beta-thalassemia by stabilizing the mutant beta-globin. Further in vitro and in vivo validation is needed to confirm the results since in silico approaches alone cannot be relied upon. This study underlines computational drug repurpose as a promising strategy for treatment of Beta-Thalassemia.

Computational Analysis of the Structural and Functional Impact of the PRKN Gene Mutation (c.1130G>A) in Parkinson’s Disease
type: item
description: Parkinson’s disease (PD) is a neurodegenerative disorder associated with genetic mutations, including those in the PRKN gene, which encodes the E3 ubiquitin ligase parkin. This study employed computational approaches to investigate the pathogenic effect of the PRKN G>A mutation (position 1130) and identify potential therapeutic ligands. Comprehensive Database analysis (MalaCards, DisGeNET, OMIM) identified PRKN as a key PD-associated gene with p value (P < 0.05), pathogenicity analysis (MutationTaster, FATHMM, Polyphen-2) confirmed the mutation as deleterious, while protein stability (I- I-mutant, Mu Pro) revealed protein destabilization. Molecular docking simulations demonstrated N-aryl benzimidazole enhanced binding affinity for the mutant PRKN (−7.5 kcal/mol vs. −5.5 kcal/mol in wild-type), mediated by salt bridges (GLU, GLU) and hydrophobic contacts, contrasting kinetin showed no mutation-dependent affinity changes (-5.6 kcal/mol). Protein-protein interaction networks (STRING) further implicated mutant PRKN in disrupted mitochondrial regulation. These findings highlight N-aryl benzimidazole as a promising therapeutic candidate for mutation-specific PD treatment and provide a computational framework for targeting genetic subtypes of neurodegenerative diseases.

Epidemiological Study of Parkinson’s disease in the Population of Khyber Pakhtunkhwa-Pakistan
type: item
description: Parkinson’s disease (PD) is a neurological disorder characterized by motor impairment affecting millions of people globally. Significantly, in Pakistan approximately 450,000 PD cases have been reported previously. This study aims to ascertain the prevalence of PD in Khyber Pakhtunkhwa a province of Pakistan. Interviews were conducted with PD patients, admitted to the Department of Neurology Lady Reading Hospital, Peshawar. Already prepared questionnaires were used to record the clinical and demographic data on the basis of age, gender, comorbidities, and family history. Clinically, it was identified that Parkinson’s patients showed different features such as tremors, muscle rigidity, bradykinesia, difficulty walking, dementia, frequent falls, weakness, difficulty speaking, sleeplessness, apathy, and dyskinesia. According to the statistical analysis, PD primarily affected those between the ages of 55 and 64 and it was more common in men than women. The significance of this study was to explain the epidemiological and clinical features of PD in the KP province of Pakistan. The current study will support accurate diagnosis and treatment as well as disease management.

A Systematic Review of Genetic, Clinical, and Gender Associated Aspects of the SNCA Gene in Familial Parkinson’s Disease
type: item
description: Parkinson's disease (PD) presents as a progressive neurological disorder that manifests through motor symptoms such as tremors and movement stiffness, which drastically affect both mobility and quality of life. This is caused by dopamine-producing cells in the brain. The worldwide prevalence is estimated at 149 cases per 100,000 persons, indicating a rise to 25.2 million by 2050. By conducting a comprehensive PubMed database search for SNCA AND Parkinson's from 2020 to 2025, with adult populations as the focus, the researchers identified relevant studies for data extraction and analysis. The SNCA gene holds critical significance because it produces alpha-synuclein, which forms toxic Lewy bodies in brain tissue. Rare SNCA mutations that result in gene multiplication trigger severe early-onset Parkinson's disease, while common genetic variations such as REP1 polymorphism increase idiopathic PD risk. Research indicates that individuals with longer SNCA-Rep1 alleles have a greater chance of developing Parkinson's disease while also experiencing worsening cognitive impairment and non-motor symptom severity. Men exhibit a 1.5-2 fold higher prevalence of Parkinson's disease and experience symptoms earlier in life compared to women, but women display tremors more frequently when diagnosed with the disease. Female patients show elevated striatal dopamine measurements while experiencing symptoms and describe a greater intensity of pain and emotional responses. The evaluation of motor symptoms like bradykinesia through gyroscope signals demonstrates potential since it aligns closely with clinical rating scales such as the Unified Parkinson's disease rating scale (UPDRS). Many non-motor symptoms, including neuropsychiatric difficulties, sleep disorders, and autonomic dysfunction, affect up to 95% of patients with hyposmia and lower quality of life before motor symptoms appear. Analysing how genetics and gender contribute to symptom development is crucial for developing improved…

type: item
description: Pleurotus ostreatus is a popularly consumed species due to its taste, flavor, large values of nutrition, and pharmacological products. This research aims to investigate the nutritional, medicinal, and toxicological properties of locally cultivated oyster mushrooms in Khyber Pakhtunkhwa, Pakistan. The study consists of the evaluation of the presence of toxins using HPLC, proximate composition, nutritional profile, hemolytic activity (against human erythrocytes), cytotoxic activity (against brine shrimp), antibacterial potential, and anticancer properties of crude methanolic extract of P. ostreatus. Toxicological evaluation through HPLC revealed the presence of ochratoxin A (3.4 ppb) and Penicillic acid (2.7 ppb). Proximate analysis showed that the moisture content in 5 g of P. ostreatus was approximately 3.00±01%, 3.6±0.5% of proteins, 10.5±0.4% of crude fiber, 1.5±01% of lipids, and 89.3% of carbohydrates. Similarly, the mineral profile showed the presence of Fe, Mg, Na, Zn, Cr, Mn, and K. During hemolytic activity, the biocompatibility of extract towards human RBCs was free from the risk. The cytotoxic effects on shrimps were minimal and were found to be safe for living cells with a 64.57 LC50 value. The extract showed maximum antibacterial activity against P. aeruginosa, E. amnigenus, E. coli, E. cloacae, Citrobacter, and S. Serratia. The extract also showed noticeable cytotoxic activity on human Rhabdomyosarcoma cell lines. Overall, our results indicated that locally cultivated mushroom (P. ostreatus) is a rich source of nutrients and therapeutic agents with obscure toxicity.

Mutational Analysis of Carbapenem Resistance Genes in Citrobacter Freundii Isolated from Urinary Tract Infections (UTIs) Patients, Peshawar
type: item
description: In the current era, pathogens become more virulent due to the development of resistance against the major families of antibiotics. The most common infection which is both community-acquired and hospital-acquired is the Urinary tract infection (UTI). The current study is intended to determine the mutational analysis of carbapenem resistance in the isolates of Citrobacter freundii isolated from UTI patients. A total of 145 urine samples were collected from the UTI suspected patients at Khyber Teaching Hospital, (Peshawar, Pakistan). Out of 145 samples, 40 samples were detected as positive isolates of C. freundii. The phenotypic identification of isolates was done via API-10S kit. The carbapenem antibiotic resistance genes were detected via Polymerase Chain Reaction (PCR). The antibiotic susceptibility testing was done via Kirby Bauer method and the results revealed that the isolates were highly resistant towards cefepime (97.5%), amoxicillin (95%), and meropenem (92.5%). The molecular analysis revealed that the VIM gene was detected in 3 isolates, the NDM-1 gene in 6 isolates, and the OXA-48 gene was detected in 4 isolates of C. freundii. The result of Next generation sequencing revealed that no mutation was detected in the sequences of these carbapenem resistance genes. The output of the current study concluded that carbapenem resistance is emerging rapidly mainly in the uropathogens and the antibiotic resistance genes enhance the ability of uropathogens to combat against antibiotics.

Molecular characterization of β-Thalassemia in Mehsud and Wazir tribes of inbreed Pashtun Population showed different patterns, indicating genetic heterogeneity for β-Thalassemia
type: item
description: β-Thalassemia (β-thal) is a monogenic disorder characterized by mutations in the HBB gene, which affect globin production, leading to hypochromic and microcytic anemia. This hereditary blood condition is marked by a decreased or absent synthesis of the β-globin chain of hemoglobin. It is notably prevalent in regions with a high prevalence of consanguineous marriages, such as the Pashtun population. The present study aimed to assess and compare the incidence of the most commonly occurring mutations of β-thalassemia in the Mehsud and Wazir tribes of Pashtun ethnicity. Additionally, the study examined the inheritance patterns of these mutations in patients and explored the level of consanguinity among parents. The findings hold potential significance for prenatal diagnosis (PND), genetic counseling, and carrier screening, which could help manage and reduce the occurrence of affected births within these tribes and the broader Pashtun population. This study involved the collection of 230 peripheral blood samples from affected patients, their parents, and siblings from families with at least one transfusion-dependent child, as well as sporadic patients from the Mehsud tribe. These samples were collected from various areas of the South Waziristan tribal district in the Mehsud region of Khyber Pakhtunkhwa (KP), Pakistan. A similar approach was followed for collecting 230 blood samples from the Wazir tribe, residing in different areas of the Frontier Region (FR) Bannu, KP, Pakistan. All samples were analyzed using the Amplification Refractory Mutation System Polymerase Chain Reaction (ARMS-PCR) technique to detect the six most common β-thalassemia mutations prevalent among Pashtun populations. The findings revealed some unique characteristics, particularly within the Mehsud tribe. The most prevalent mutation in this tribe was codon 41/42 (–TTCT), followed by frameshift codons FSC 8/9 (+G) (HBB: c.27_28insG), IVS-I-5 (G>C), and FSC-5 (–CT). Interestingly, the mutation spectru…

The molecular characterization of β-Thalassemia in Afridi and Wazir tribes of inbreed Pashtoon population showed different patterns, indicating genetic heterogeneity for β-Thalassemia
type: item
description: β-Thalassemia (β-thal) is a monogenic disease resulting from mutations in the HBB gene, leading to aberrant globin production and causing hypochromic and microcytic anemia. The current study aimed to assess and compare the incidence of the most frequently occurring mutations of beta-thalassemia in sub-tribes Afridi and Ahmadzai of the Wazir tribe belonging to the Pashtoon Ethnicity, additionally the study investigated the inheritance pattern of these mutations in affected patients and the prevalence of consanguinity among the parents. Furthermore, this study holds potential significance in the context of prenatal diagnosis (PND), Genetic counseling, and carrier screening to control the occurrence of affected births not only in these tribes but in the entire Pashtoon Population. During the current research, 300 peripheral blood samples of affected patients, their parents, and siblings were compiled both from families having at least one transfusion-dependent child and sporadic patients from Ahmadzai Wazir residing in different areas of Wazir subdivision Banu Khyber Pakhtunkhwa (KPK), Pakistan. The same procedure was followed for collecting 300 peripheral blood samples from Afridi Wazir residing in different areas of Wazir sub-division Banu and Nort Waziristan Tribal District (NWTD), KPK, Pakistan. These samples were analyzed for the six most common β-thalassemia mutations found in the Pashtun population via the amplification refractory mutation system-polymerase chain reaction (ARMS-PCR) technique.

Molecular Characterization of Sulfonamide and Fluoroquinolone Resistant Genes of Morganella morganii Isolates from Urinary Tract Infections (UTIs) Patients, Peshawar
type: item
description: Uropathogens pose a significant threat to public health, affecting both community and hospitalized patients. Among these, Gram-negative bacteria represent a predominant group. In recent years, Morganella morganii has emerged as a notable cause of urinary tract infections (UTIs) worldwide, with a concerning rise in prevalence attributed to the evolution of resistance mechanisms against multiple antibiotics. The present study aimed to investigate the prevalence of M. morganii, its associated antibiotic-resistance genes, and its correlation with demographic factors such as gender and age. The findings revealed that M. morganii was more frequently isolated from females (n = 27) than males (n = 16). The highest prevalence rate (37.2%) was observed in the age group of 21–40 years. The antibiotic susceptibility profile of M. morganii isolates indicated high resistance to cotrimoxazole (77%), followed by ciprofloxacin (67%), Cefoperazone (65%), cefotaxime (58%), gentamicin (28%), amoxicillin-clavulanate (26%), imipenem (16%), Fosfomycin (9%), meropenem (7%), piperacillin-tazobactam (7%), and amikacin (5%). PCR analysis revealed the presence of antibiotic-resistance genes in the resistant isolates. Among cotrimoxazole-resistant isolates, the sul1 and sul2 genes were detected in 23 isolates each. Similarly, in ciprofloxacin-resistant isolates, the gyrA and gyrB genes were identified in 11 and 10 isolates, respectively. Interestingly, certain isolates harbored various combinations of these resistance genes. Seven isolates contained all four resistance genes (sul1, sul2, gyrA, and gyrB), while seven isolates harbored three genes in combinations (sul1, sul2, gyrA or sul1, sul2, gyrB). Nine isolates exhibited two-gene combinations (sul1 and sul2).

Molecular Detection and Characterization of Efflux Pump Genes Associated with Multidrug Resistance in Clinical Isolates of Staphylococcus aureus in Peshawar, Pakistan
type: item
description: Staphylococcus aureus is an opportunistic pathogen responsible for a wide range of human diseases. It is renowned for its capacity to develop resistance to multiple antibiotics, primarily due to diverse resistance mechanisms, including efflux pumps, which significantly contribute to intrinsic resistance. This study aimed to investigate the expression of efflux pump genes, namely NorA, MepA, and MdeA, in clinical isolates of S. aureus obtained from Khyber Teaching Hospital and Hayatabad Medical Complex. A total of 200 clinical samples were collected. The samples were initially cultured on Mannitol salt agar and identified based on physical characteristics and biochemical tests, including catalase and coagulase assays. Molecular confirmation of S. aureus isolates was performed using the mecA gene, which is specific to this bacterium. Antibiotic susceptibility testing was conducted following CLSI guidelines to determine resistance patterns against a panel of antibiotics. The presence of efflux pump resistance genes (norA, mgrA, mepA, mepR, and mdeA) was detected using polymerase chain reaction (PCR). Among the 17 antibiotics tested, the highest resistance was observed against ciprofloxacin, penicillin, ampicillin, and cefoxitin. Out of 200 isolates, 177 were resistant, with various efflux pump genes detected. Statistical analysis using ANOVA (Single Factor) revealed significant findings (p = 0.004). The results highlight that efflux pumps play a crucial role in intrinsic resistance mechanisms in S. aureus. Consequently, this bacterium has evolved into a multidrug-resistant pathogen, posing a significant challenge to the effective treatment of infections caused by S. aureus.

Molecular Analysis of Consanguineous Families Having X-Linked Congenital Stationary Night Blindness in Khyber Pakhtunkhwa, Pakistan
type: item
description: X-linked congenital stationary night blindness (XLCSNB) is a vision disorder characterized by reduced visual acuity, myopia (short-sightedness), strabismus, and nystagmus. This condition results from mutations affecting the transmission of visual signals in the retina. Genetic studies have identified the proximal short arm of chromosome X (Xp11.4) as the region harboring the candidate gene associated with XLCSNB. Electroretinogram (ERG), a diagnostic test, plays a critical role in differentiating XLCSNB categories by evaluating the electric responses of retinal, bipolar, and ganglion cells to light and dark stimuli. To locate the candidate gene, four microsatellite markers (DXS574, DXS8012, DXS993, and DXS1201) were designed near the proximity of the target region on Xp11.4. The gene was identified as the NYX gene, encoding nyctalopia, a 481-amino-acid protein, and a member of leucine-rich repeats (LRR). Nyctalopia plays a pivotal role in signal transmission between retinal and bipolar cells. The expression of the NYX gene is low in tissues such as muscles, the brain, the retina, and the testis. Following linkage analysis, specific primers were designed to amplify both exons of the NYX gene. Gel electrophoresis was used to observe DNA bands, and subsequent sequencing of the gene was performed to identify mutations associated with XLCSNB. Three mutations were identified in the NYX gene, all of which had been reported previously. These mutations, predominantly splicing mutations, are known to be pathogenic alterations. The NYX gene encodes 13 leucine-rich repeats (LRRs), and the identified missense mutations primarily affect these LRR sites, leading to impaired retinal signal transmission and disturbed eye function. To date, 42 different mutations in the NYX gene have been reported, with splicing mutations being the most common. This study successfully identified mutations in the NYX gene associated with XLCSNB. Although previously reported, the findings provide furth…

Epidemiological Analysis of Epilepsy Prevalence in the Pashtun Population: A Comparative Study in Khyber Pakhtunkhwa, Pakistan
type: item
description: Epilepsy is a significant neurological disorder with a high prevalence in low- and middle-income regions, including Khyber Pakhtunkhwa (KP), Pakistan. Despite advancements over the past two decades, limited epidemiological data is available regarding the clinical and demographic features of epilepsy in this region. Socioeconomic barriers and cultural factors further impair the treatment gap. This study aimed to investigate the prevalence and clinical characteristics of epilepsy in the Pashtun population of KP, focusing on factors such as age, gender, parental consanguinity, and family history. A cross-sectional study was conducted at the Department of Neurology, Lady Reading Hospital (LRH), Peshawar. Data was collected through structured interviews and questionnaires from epileptic patients admitted to the hospital. The study analyzed demographic and clinical factors, including disease onset, age, gender, parental consanguinity, and family history. Among the surveyed population, males were found to be more affected by epilepsy compared to females. The highest prevalence was observed in individuals aged 11 to 20 years. Many patients reported parental consanguinity, indicating a possible genetic predisposition. Additionally, a family history of epilepsy was frequently observed, further emphasizing the hereditary nature of the disorder in the study population. The study highlights key epidemiological patterns of epilepsy in KP, with a higher prevalence among males and adolescents. The outcomes underscore the importance of addressing genetic factors and implementing targeted public health interventions, including early diagnosis and community education, to reduce the treatment gap and improve regional patient outcomes.

Systematic Review of Emerging Technologies in Cystic Fibrosis Treatment: Gene Therapy and CRISPR Strategies for the Future
type: item
description: The current systematic review aimed to evaluate research on cystic fibrosis (CF), a genetic disease that affects multiple organs, particularly the lungs, and is associated with high morbidity and mortality. A total of 7831 relevant studies were identified from search databases, and 27 studies were ultimately considered appropriate for review after applying eligibility criteria including three longitudinal studies and the remaining cross-sectional ones. All studies included a healthy control group, with a combined total of 1839 individuals with CF and 2178 controls. The age range varied across studies, but the majority were carried out in adults. The studies had different aims, including evaluating and comparing different techniques for gene therapy and CRISPR, and assessing changes in body nutrition status. Other studies focused on the evaluation of lung function, inflammation, and clinical parameters. Animal models have played a crucial role in advancing CF gene therapy. Various animal models have been developed, including pigs, ferrets, rats, zebrafish, and sheep, each with its advantages and limitations. The CF pig model has facilitated the measurement of CFTR correction in vivo, which enhances the correlation of CFTR expression and transportation of Cl- and HCO3 as a result decreases the implication of cystic fibrosis in gene therapy. Gene editing technologies, such as CRISPR/Cas9, have emerged as promising approaches to modifying nucleic acid sequences in CF research. These tools hold the potential to repair the endogenous CFTR gene and restore its function, but efficient in vivo gene delivery remains a significant challenge. Assessing changes in body composition can provide valuable information on the effects of gene therapy or CRISPR on the overall health of CF patients. The proper evaluation of nutritional composition in the CF treatment is essential, as current therapies such as CFTR modulators primarily target the respiratory system and may not fully addre…
