Abstract
BACKGROUND & OBJECTIVE Rape is a severe kind of sexual violence that represents a significant violation of human rights. The objective was to investigate the demographic and clinical features of female survivors of sexual assault in Lahore, Pakistan. METHOD A retrospective study was conducted at the Department of Forensic Medicine of Lahore General Hospital, analysing records of female sexual assault survivors investigated by affiliated police stations from November 2020 to November 2022. Data were collected from medicolegal certificates and medical notes and analysed using SPSS software. RESULT 282 female survivors reported to Lahore General Hospital's Forensic Medicine Department, aged 5-55 years, with a mean age of 22.74 ± 8.30. A significant proportion (50.4%) were aged 16-25 years. Most survivors were examined between 6 and 24 h (34%) and 2-7 days (37.9%) after the assault, with the majority (95%) exhibiting well-developed secondary sexual characteristics. Sexual assault and physical abuse were both reported in 56.4% of cases. In 77% of cases, the perpetrator was known, and in 36.5% of cases, a weapon was used. No external body injury was observed in 74.8% of cases, and 2.8% showed signs of fresh hymen rupture. The study identified 92.2% of cases lost to follow-up. CONCLUSION This study highlights the pressing need to implement effective measures to prevent and address rape in Pakistan. The findings emphasise the need for education, improved forensic infrastructure and policy reforms to address sexual assault effectively.

Abstract
Sustainable development relies heavily on a food system that is both safe and secure. Several approaches may lead to sustainability and food safety. An increase in the cultivation of legume crops is one of the approaches for enhancing agricultural viability and ensuring adequate food supply. Legumes may increase daily intake of fiber, folate, and protein as substitutes for meat and dairy. They are also crucial in various intercropping systems worldwide. However, legume production has been hampered by Rhizoctonia solani due to its destructive lifestyle. R. solani causes blights, damping off, and rotting diseases in legume crops. Our knowledge of the global distribution of R. solani associated with legume crops (alfalfa, soybean, chickpea, pea, lentil, common bean, and peanut), detection, diagnosis, and management of legume crops diseases caused by R. solani is limited. Traditional approaches rely on the incubation of R. solani, visual examination of symptoms on host legume crops, and microscopy identification. However, these approaches are time-consuming, require technical expertise, fail to detect a minimal amount of inoculum, and are unreliable. Biochemical and molecular-based approaches have been used with great success recently because of their excellent sensitivity and specificity. Along with conventional PCR, nested PCR, multiplex PCR, real-time PCR, magnetic-capture hybridization PCR, and loop-mediated isothermal amplification have been widely used to detect and diagnose R. solani. In the future, Next-generation sequencing will likely be used to a greater extent to detect R. solani. This review outlines global distribution, survival, infection and disease cycle, traditional, biochemical, molecular, and next-generation sequencing detection and diagnostic approaches, and an overview of the resistant resources and other management strategies to cope with R. solani.

Abstract
BACKGROUND Adolescence is when an individual undergoes development and growth. Many studies suggest variations in the number and size of blood cells during this period in various individuals. The full blood count (FBC) is often the starting point of medical investigations, which help diagnose a wide range of illnesses, infections, and diseases. This study aimed to report the mean FBC values and compare them by gender and ethnicity, using blood results from the thalassemia screening programme in Seremban District, Malaysia. MATERIALS AND METHODS This cross-sectional study used secondary data from the thalassemia screening programme on Form 4 students aged 15-16 years from January 2018 to October 2018 by the Seremban District Health Office, Malaysia. These students participated in the thalassemia screening programme in which their blood samples were taken for FBC analysis. The data were extracted for this study. RESULTS There were statistically significant gender-based differences for total white blood cell (WBC) count, neutrophils, lymphocytes, mixed WBC, and platelets. It was also observed that ethnic-specific differences were statistically significant for RBC count, platelets, platelet distribution width and mean platelet volume. CONCLUSION This study was able to report the mean FBC values among Malaysian adolescents with respect to their gender and ethnicity, of which there is a lack of published data.

Abstract
The present work reports application of auxetic yarns in development of abrasion resistant socks which can be used for better serviceability without shoes even on rough surfaces. Socks used in the current research were produced by using helical auxetic yarns which consist of different combinations of high performance and conventional materials e.g. Kevlar P-AR (para-aramid), cotton, elastomeric yarn, polyamide (PA6) and polyester with same linear density of 74 Tex. Three different types of fabrics were produced e.g. flat knit, sandwich half terry short and sandwich half terry long. For investigating the auxeticity, all samples were subjected to tensile loading and the resulting change in their thickness was measured. Abrasion resistance and other comfort related properties e.g. air permeability, vertical wicking and absorbency were also evaluated. The influence of different yarn combinations, twist levels and fabric types on abrasion resistance and breathability of socks were investigated by using fractional (half) factorial design. Statistical analysis was performed for the obtained results by using analysis of variance. Conventional socks samples were also produced in all fabric types for comparison with the auxetic materials. From the results it was concluded that the overall abrasion resistance of auxetic yarn-based sock is higher than conventional cotton sock. Results also revealed that abrasion resistance was increased by 46% in flat knit socks sample, 50% in sandwich half terry short sample and 58% in sandwich half terry long sample as compared to conventional cotton sock. In addition to this all the socks samples exhibited good comfort/breathability properties.

Abstract
Physids belong to Class Gastropoda; belong to Phylum Mollusca and being bioindicators, intermediate hosts of parasites and pests hold a key position in the ecosystem. There are three species of Genus Physa i.e. P. fontinalis, Physa acuta and P. gyrina water bodies of Central Punjab and were characterized on the basis of molecular markers High level of genetic diversity was revealed by polymorphic RAPD, however SSR markers were not amplified. The multivariate analysis revealed polymorphism ranging from 9.09 percent to 50 percent among the three Physid species. Total number of 79 loci were observed for the three species under study and 24 loci were observed to be polymorphic. These RAPD fragment(s) can be developed into co dominant markers (SCAR) by cloning and can be further sequenced for the development of the Physa species specific markers to identify the introduced and native species in Pakistan.

Abstract
Physids belong to Class Gastropoda; Phylum Mollusca have important position in food web and act as bio indicators, pests and intermediate host. Being resistant these are called cockroaches of malacology. Physid snails were collected from different water bodies of Faisalabad (Punjab) and were identified up to species using morphological markers. The morphometry of the specimens was carried out with the help of a digital Vernier caliper in millimeters (mm) using linear measurement of shell characters. Linear regression analysis of the AL/SW ratio vs AL and SL/SW ratio vs AL indicated that allometric growth exists only in Physa acuta when compared with P.gyrina and P. fontinalis. This study will lead to assess the status of the Physid species in Central Punjab. The Principal component analysis shows that the Component 1 (Shell Length) and component 2 (Shell Width) are the most prolific components and nearly 80 percent of the identification. The distance between P. acuta and P. fontinalis is 5.4699, P. acuta and P. gyrina is 7.6411, P. fontinalis and P. gyrina is 16.6080 showing that P. acuta resembles with P. fontinalis, and both these specimens donot resemble with P. gyrina. P.acuta is an invasive species and shows bioactivity making it a potent candidate for bioactive substances.

Abstract
Nature has provided prodigious reservoirs of pharmacologically active compounds for drug development since times. Physcion and physcion 8-O-β-D-glucopyranoside (PG) are bioactive natural anthraquinones which exert anti-inflammatory and anticancer properties with minimum or no adverse effects. Moreover, physcion also exhibits anti-microbial and hepatoprotective properties, while PG is known to have anti-sepsis as well as ameliorative activities against dementia. This review aims to highlight the natural sources and anticancer activities of physcion and PG, along with associated mechanisms of actions. On the basis of the literature, physcion and PG regulate multitudinous cell signaling pathways through the modulation of various regulators of cell cycle, protein kinases, microRNAs, transcriptional factors, and apoptosis linked proteins resulting in the effective killing of cancerous cells in vitro as well as in vivo. Both compounds effectively suppress metastasis, furthermore, physcion acts as an inhibitor of 6PGD and also plays an important role in chemosensitization. This review article suggests that physcion and PG are potent anticancer drug candidates, but further investigations on their mechanism of action and pre-clinical trials are mandatory in order to comprehend the full potential of these natural cancer killers in anticancer remedies.

Abstract
In this study, zinc ferrite nanoparticles (ZF-NPs) were synthesized using aqueous seed extract of Piper nigrum as a bio-reducing and stabilizing agent. FTIR, SEM, FE-SEM, XRD, and TGA have been used for characterizing ZF-NPs. The results showed that Piper nigrum stabilized ZF-NPs have high purity and size range of 60-80 nm. The performance of the ZF-NPs has been investigated by photocatalytic reduction of methylene blue (MB) in the presence of sunlight. The factors responsible for affecting the degradation values of the reaction were also explored for developing a better understanding of the phenomenon.

Abstract
Conversion of nitroaniline (NA), a highly toxic pollutant that has been released into aquatic systems due to unmanaged industrial development in recent years, into the less harmful or a useful counterpart is the need of the hour. Various methods for its conversion and removal have been explored. Owing to its nominal features of advanced effectiveness, the chemical reduction of 4-NA using various different nanocatalytic systems is one such approach that has attracted tremendous interest over the past few years. The academic literature has been confined to case studies involving silver (Ag) and gold (Au) nanoparticles, as these are the two most widely used materials for the synthesis of nanocatalytic assemblies. Focus has also been given to sodium borohydride (NaBH4), which is used as a reductant during the chemical reduction of NA. This systematic review summarizes the fundamentals associated with the catalytic degradation of 4-NA, and presents a comprehensive and critical study of the latest modifications used in the synthesis of these catalytic systems. In addition, the kinetics, mechanisms, thermodynamics, as well as the future directions required for understanding this model reaction, have been provided in this particular study.

Abstract
Potential hazardous effects caused by non-biodegradable plastics are considered to be one of the most widely discussed and notable challenges of the 21st century. To address this particular problem, immense efforts have been devoted to the preparation of biodegradable plastics material. This green approach mitigates the major drawbacks e.g. improper waste management, low degradation rates, waste accumulation in water reservoirs and harmful chemical reagents hence providing a natural, economical and biodegradable alternative to the customarily employed non-biodegradable plastics. This review provides an insight into recently engineered biodegradable plastics used for packaging applications. Properties such as barrier/permeation indexes, thermal, electrical and mechanical characteristics of the biodegradable plastics are considered in detail for developing an understanding regarding the fundamentals of biodegradable materials. Recent literature (2010-2018) was classified according to the composition and nature of the used material. Materials such as polylactic acid, polyhydroxyalkanoates, polyhydroxybutyrate, polycaprolactone, starch and cellulose were comprehensively discussed along with their properties and blending agents.

Abstract
Susumu Ohno hypothesized that the diversity of vertebrate gene families and genome is due to two rounds of whole genome duplications (also referred as 2R hypothesis). The quadruplicate paralogous blocks present on 1/2/8/20 chromosomes are taken as one of the evidences in favor of the 2R. In this study, we investigated that whether 2R has shaped the vertebrate evolution using gene families residing on chromosomes 1/2/8/20. Evolutionary history of 22 gene families (11 from the current study and 11 from the previous study) was evaluated by the phylogenetic analysis with triplicated or quadruplicated distribution on these human chromosomes 1/2/8/20. The phylogenetic analysis was performed using high-quality whole genomic sequence data of multiple species with neighbor-joining (NJ) and maximum likelihood (ML) methods. The phylogenetic tree topology of these gene families revealed variable duplication time points during invertebrate-vertebrate evolution. Topology comparison approach categorized 22 gene families into three groups. Tree topologies of ten gene families fell into Group 1 (duplications prior to invertebrate-vertebrate split), four in Group 2 (i.e., (AB) (C) (D), topology incongruent with 2R) and eight in Group 3 (((AB) (CD)), 2R congruent topology). Therefore, taken together the current and previous data of 1/2/8/20 paralogons, we propose that, in addition to whole genome duplications events, current developmental, morphological and genomic complexity of the vertebrate genomes may also have originated through segmental duplications occurring at varying time points during the course of animal evolution.

Abstract
In this study, poly(N-isopropylmethacrylamide-co-methacrylic acid) microgels prepared by free radical precipitation polymerization were used as micro-reactors for the synthesis and stabilization of silver nanoparticles. UV-Visible spectroscopy, Transmission Electron Microscopy and Fourier-transform infrared spectroscopy were used to characterize both pure and hybrid microgels. The catalytic reduction of 4-nitroaniline was carried out in the presence of hybrid microgels to test their catalytic activity, and the catalysis mechanism was explored by varying the concentrations of reacting species like 4-nitroaniline and NaBH4, as well as the dose of the catalyst. The kinetic data indicates that this reaction follows pseudo-first order. The variation in apparent rate constant (kapp) with respect to NaBH4 concentration also discloses it to be the following Langmuir-Hinshelwood mechanism. The relationship between catalyst concentration and apparent rate constant was found to be increasing in a linear manner. The data obtained also confirmed that silver nanoparticles loaded microgels have the potential to be used as an excellent micro-reactor for selective reduction of 4-nitroaniline to p-phenylenediamine.

Abstract
BACKGROUND & OBJECTIVE Kunitz-type venoms are bioactive proteins isolated from a wide variety of venomous animals. These venoms are involved in protease inhibitory activity or potassium channel blocking activity. Therefore, they are reported as an important source for lead drug candidates towards protease or channel associated diseases like neurological, metabolic and cardiovascular disorders. METHODS This study aimed to check the inhibitory action of Kunitz-type venoms against potassium channels using computational tools. RESULTS Among potassium channels, Human Voltage-Gated Potassium Channel 1.2 (hKv1.2) was used as a receptor whereas Kunitz-type peptides from the venoms of various species were selected as ligand dataset. CONCLUSION This study helped in finding the binding interface between the receptor and ligand dataset for their potential therapeutic use in treating potassium channelopathies.

Abstract
Many clinical-pathogens have developed resistance against known antibiotics and there is an urgent need for the discovery of novel antibiotics. In this study, low molecular weight peptides were isolated from seeds/leaves of 20 medicinal plants and tested for their antibacterial activity against laboratory strains of S. aureusand P. aeruginosa. Peptides isolated from Peganum harmala (PhAMP) exhibited maximum activity against laboratory strains. As clinical-isolates are more virulent and resistant to antibiotics, we tested the potential of PhAMP on these bacterial strains isolated from infected wounds. Pathogens isolated from burn-wounds (S. aureus, P. aeruginosa and K. pneumoniae) and surgical-wounds (P. aeruginosa and K. pneumoniae) exhibited zones of inhibition against PhAMP when tested by disc diffusion method. Biofilm formation of wound pathogens in the presence/absence of PhAMP was analyzed to check its effect. Surgical-wound pathogens and K. pneumoniae from burn-wound showed significant reduction in biofilm formation and planktonic bacteria. While biofilms of S. aureus and P. aeruginosa from burn-wound showed resistance against PhAMP. An effective antibiotic treatment should not only inhibit but should also disrupt already developed biofilms. PhAMP was very effective in the disruption of developed biofilm of all pathogens after 36 hours. This data unravels the potential of PhAMP as a novel, natural antibiotic against clinical-pathogens.

Abstract
BackgroundEgo defense mechanisms, defined by Freud as unconscious resources used by the ego to reduce conflict between the id and superego, are a reflection of how an individual deals with conflict and stress. Vaillants’ proposed Hierarchy of Defenses states that mature defenses are associated with better adaptive functioning and health, as opposed to immature defense which are correlated negatively with measures of adaptive adult functioning.ObjectivesThis study assesses the prevalence of various ego defense mechanisms employed by medical students of Karachi, which is a group with higher stress levels than the general population.MethodsA questionnaire based cross-sectional study was conducted on 682 students from five major medical colleges of Karachi in November 2006. Ego defense mechanisms were assessed using the Defense Style Questionnaire(DSQ-40) individually and as grouped under Mature, Immature, and Neurotic factors.ResultsNeurotic defenses had a higher mean score(5.62) than Mature(5.60) and Immature(4.78) mechanisms. Immature mechanisms were more commonly employed by males whereas females employed more Neurotic mechanisms than males. Neurotic and Immature defenses were significantly more prevalent in first and second year students. Mature mechanisms were significantly higher in students enrolled in Government colleges than Private institutions (p< 0.05).ConclusionsNeurotic mechanisms are more commonly encountered than Mature or Immature mechanisms among medical students of Karachi, and this could reflect greater stress levels than the general population. Employment of these mechanisms was associated with female gender, enrollment in a private medical college, and students enrolled in the first 2 years of medical school.

Abstract
We retrospectively analyzed the results of 75 living-related pediatric renal transplants performed at our center between January 1986 and December 1999. The major causes of end-stage renal disease (ESRD) were glomerulonephritis (26%) and nephrolithiasis (16%), while the etiology was unknown in 50%. The mean age of the recipients was 12 yr (range 6-17 yr) and that of the donors was 39 yr (range 20-65 yr). The majority (73%) of donors were parents. Eighty five per cent of donors were one-haplotype matched and the rest identical. Immunosuppression was based on a triple drug regimen. Thirty per cent of recipients were rapid metabolizers of cyclosporin A (CsA) (area under the curve [AUC]: < 6,000 ng/mL/h), while 16% were slow metabolizers (AUC: > 8,000 ng/mL/h). Forty three (57%) children encountered 59 rejection episodes, the majority of which (59%) were recorded in the first month post-transplant. Seventy-four per cent of the rejection episodes were steroid sensitive and the rest, except two, were resolved by therapy with antithymocyte globulin (ATG) or orthoclone thymocyte 3 (OKT3). After a mean follow-up of 37 months, 17 (22%) grafts had chronic rejection and 76% of these recipients had previously experienced acute rejection episodes. The overall infection rate was high, necessitating two hospital admissions/patient/year. The majority (53%) of the infections were bacterial. Urinary tract infections (UTIs) were seen in 17 (23%) recipients. Twelve of these had ESRD as a result of stone disease and eight grafts were lost because of UTIs. Eight per cent of recipients developed tuberculosis (TB), and extra-pulmonary lesions were seen in 50%. Surgical complications were encountered in eight patients. Free medication to all recipients and parental support ensured a compliance rate of 93%. Baseline growth deficit was seen in children of the two groups studied (the 6-12 yr and 13-17 yr age-groups), with Z-scores of - 2.39 and - 2.12, respectively. No growth catch-up was observed at 12 and 24 months in either group. Post-donation complications were seen most commonly in donors > 50 yr of age and included: proteinuria (> 300 mg/24 h, four patients), hypertension (three patients), and diabetes (one patient). Twenty-four grafts were lost, 54% as a result of immunological and the rest as a result of non-immunological causes, and 17 recipients died during the follow-up period. Infections were the main cause of patient and graft loss. Overall 1- and 5-yr graft and patient survival rates were 88% and 65%, and 90% and 75%, respectively.

Abstract
It has been suggested that girls and women coming from a Muslim background in the Asian sub-continent are disadvantaged in the educational sphere. In this study two particular aspects of this suggested disadvantage are investigated. First, the importance of educating males rather than females and secondly, the issue of parental and husband's control over the rights of women to education and work. Twenty-six Muslim females living in a large Scottish town but of a Pakistani Punjabi background were interviewed in depth. The findings, that these women considered that it is as important to educate girls as it is to educate boys, and that they acquiesced in parental and husband's control over the rights of females to be educated and work, are discussed within a cross-cultural perspective. It is concluded that such issues cannot be isolated from traditional values about the importance of upholding family honour.

Abstract
A 5-day study, forming the initial part of two 32-day clinical trials and involving 22 unipolar depressed inpatients, was designed to determine the relationship between response to sleep deprivation and 24-hour urinary MHPG levels. A statistically significant, positive relationship was noted between the sleep deprivation, modified total HAM-D scores and MHPG levels at postsleep deprivation, indicating that the greater the severity of depression during sleep deprivation the higher were the MHPG levels after the sleep deprivation period.
