ABSTRACT
Abstract Transplanting time and genotype contribute to improving crop yield and quality of eggplant (Solanum melongena L.). A field experiment was conducted to investigate the impact of foliar applied of triacontanol (TRIA) and eggplant genotypes 25919, Nirala, 28389 and Pak-10927,transplanted on 1 March,15 March, and 1 April on exposure to high air temperature conditions. The experiment was performed according to Randomized Complete Block Design and the data was analyzed by using Tuckey,s test . The TRIA was applied at 10µM at flowering stage; distilled water was used as the control. Rate of photosynthesis and transpiration, stomatal conductance, water use efficiency, and effects on antioxidative enzymes (superoxide dismutase, catalase and peroxidase) were evaluated. The 10µM TRIA increased photosynthesis rate and water use efficiency and yield was improved in all genotypes transplanted at the different dates. Foliar application of 10µM TRIA increased antioxidative enzyme activities (SOD, POD & CAT) and improved physiological as well as biochemical attributes of eggplant genotypes exposed to high heat conditions. Highest activity of dismutase enzyme 5.41mg/1g FW was recorded in Nirala genotype in second transplantation. Whereas, lowest was noted in PAK-10927 (2.30mg/g FW). Maximum fruit yield was found in accession 25919 (1.725kg per plant) at 1st transplantation with Triacontanol, whereas accession PAK-10927 gave the lowest yield (0.285 kg per plant) at control treatment on 3rd transplantation. Genotype, transplanting date and application of TRIA improved growth, yield and quality attributes under of heat stress in eggplant.

Taxa de fotossíntese e transpiração, condutância estomática, eficiência do uso da água e efeitos sobre as enzimas antioxidantes (superóxido dismutase, catalase e peroxidase) foram avaliados. O TRIA 10 µM aumentou a taxa de fotossíntese e a eficiência do uso da água e o rendimento foi melhorado em todos os genótipos transplantados nas diferentes datas. A aplicação foliar de TRIA 10µM aumentou as atividades das enzimas antioxidantes (SOD, POD e CAT) e melhorou os atributos fisiológicos e bioquímicos de genótipos de berinjela expostos a condições de alto calor. A atividade mais elevada da enzima dismutase 5,41mg / 1g FW foi registrada no genótipo Nirala no segundo transplante. Considerando que o mais baixo foi observado em PAK-10927 (2,30 mg / g FW). A produtividade máxima de frutos foi encontrada no acesso 25919 (1,725 kg por planta) no 1º transplante com Triacontanol, enquanto o acesso PAK-10927 deu a menor produção (0,285 kg por planta) no tratamento de controle no 3º transplante. Genótipo, data de transplante e aplicação de TRIA, melhoramento do crescimento, rendimento e atributos de qualidade sob estresse térmico em berinjela.
ABSTRACT
Abstract Naturally occurring mutations in morphogenetic protein 15 (BMP15) are associated with decreased ovulation rate (OR), litter size (LS), and sterility. It is of a great interest to elucidate BMP15 gene in Cholistani sheep breed to uplift socio-economic status and the knowledge of Cholistani sheep breeding in Southern Punjab, Pakistan. In our study, a total of 50 infertile Cholistani sheep aged between 2-6 years and having no blood relation were screened for BMP15 mutations. For this purpose, a high-quality DNA was extracted from the blood of sheep followed by primer designing, Polymerase Chain Reaction (PCR) amplification, DNA sequencing, and in silico analyses. Out of total 50 samples, 9 samples including case 1 (T3), case 2 (T8), case 3 (T17), case 4 (T22), case 5 (T25), case 6 (T33), case 7 (T40), case 8 (T44), and case 9 (T47) were found positive for a variety of already reported and novel BMP15 mutations. Further in silico analyses of the observed mutations have shown the functional impact of these mutations on different characteristics (molecular weight, theoretical PI, estimated half-life, instability index, sub-cellular localization, and 3D confirmation) of the encoded proteins, possibly altering the normal functionality. In a nutshell, findings of this study have confirmed the possible essential role of the BMP15 mutations in the infertility of the Cholistani sheep.

@#Introduction: COVID-19 outbreak is the greatest communicable disease that hit globally, caused by SARS-CoV-2 virus. Malaysia commenced a Movement Control Order (MCO) to contain the epidemic, and thereby altered consumer’s purchasing pattern drastically into online shopping, thus increase the demand of delivery services. The virus able to survive on surfaces up until 9 days depending on the type of surface. Nonetheless, the negligence of proper hygiene management among the vendor, the courier or the user can trigger fomite transmission. The aims of this study were to determine the level of awareness and readiness of fomite transmission caused by COVID-19 among Malaysian online shoppers by evaluating knowledge, precautionary measurements and psychological state. Methods: Convenience sampling method was used for data collection, and 416 respondents participated. The survey instrument comprised of 2 parts; socio-demographic characteristics and the second part consist of COVID-19 transmission as well as its survivability, precautions and psychological state during the outbreak. This was transferred to a Google form and the link was shared through social medias. Data were analysed using SPSS software v.23.0. Results: In spite of the fact that 88% of respondents worried about being infected with COVID-19 and well informed regarding fomite transmission, almost half of respondents (42.3%) did not sanitize their parcels received from outside. Conclusion: In light of this, health authorities should implement more campaigns to emphasize the utmost importance of disinfection of any foreign items by consumers and it is strongly believed that it will provide enhanced protection against fomite transmission.
ABSTRACT
An ethnobotanical study was conducted to document indigenous medicinal plants and their usage from knowledgeable and elderly persons in Razzar and Gadoon valley of Swabi and Allai and Tanawal valley of Hazara region of Pakistan during 2016-2019. Several systematic field visits and questionnaire surveys were carried out in selected sites of the study area to gather relevant information from the local community. Rapid assessment method was adopted for data collection by interviewing the local people having enough knowledge of medicinal plants use for treatment of different ailments. UV (UV) formula was applied to calculate the relative importance of medicinal plant species in each site of the study area. In the present study, 221 medicinal plants belonging to 105 families have been reported through 580 respondents (385 males, 138 females and 57 local health healer) from the Swabi and Hazara region. The main sources of herbal medicines were leaves (21%) followed by fruits (21%), seeds (17%), whole plants (14%), roots (9%), bark (9%), flowers (7%) and gum (2%). Mentha spicata L. and Berberis lycium Royle were reported with highest UV (UV) i.e. 0.92 and 0.68 in Razzar tehsil and Gadoon valley of Swabi, whereas Mentha longifolia L and Geranium wallichianum D were reported with highest UV i.e. (0.65) and (0.88) in Allai and Tanawal valley of Hazara region, respectively. It was concluded that Swabi and Hazara region is rich in medicinal plants species and associated traditional knowledge. Moreover, ethno-medicines have played significant role in the indigenous healthcare system of the study area. However, uprooting the entire plant for ethno-medicine is a big threat to conservation of medicinal plants diversity in the study area.

Background@#Salmonellosis is one of the most reported bacterial foodborne illnesses worldwide. Salmonella outbreaks are also prevalent in the Philippines, with egg-containing food and feces of chicken as implicated sources. The presence of Salmonella in eggshells and in egg content poses a significant threat to public health. Hence, this study aimed to determine the presence of S. enterica from different parts of chicken eggs sold in a public market in the City of Manila. @*Methodology@#A descriptive study design was employed to detect the presence of Salmonella spp. in different parts of retail chicken eggs. A total of 72 egg samples from 24 stalls were included. The methodology for isolation and identification of Salmonella followed the guidelines set by the US Food and Drug Administration as seen in the Bacteriological Analytical Manual with some additions and modifications. @*Results@#Contaminated eggs were found in 21 (87%) of the 24 stalls. A total of 29 (40%) out of 72 eggs were identified as the source of putative Salmonella isolates. Nineteen (66%) eggs had putative Salmonella isolates from the eggshell, while 7 (24%) had putative Salmonella isolates from the egg content. There were three (10%) eggs with both eggshell and egg content possibly contaminated with Salmonella. @*Conclusion@#The presence of putative Salmonella and Enterobacteriaceae highlight the need to strengthen food safety at the production and distribution levels of retail chicken eggs. There is also a need to establish a national surveillance system along with strengthened diagnostic capacity for S. enterica in the Philippines.

BACKGROUND@#Filipino speech-language pathologists (SLPs) can reach more persons with disabilities across 7,107 Philippine islands through telerehabilitation (also known as teletherapy, telepractice). This study described the feasibility of telerehabilitation for speech-language pathology in community-based rehabilitation in terms of appropriate information and communication technologies (ICT), stakeholder perspectives, and facilitators and barriers.@*METHODS@#A qualitative descriptive design was employed. Participants were purposely selected as telerehabilitation stakeholders. One metropolitan-based SLP conducted remote and synchronous therapy sessions to two persons with voice disorders (52 and 65 years old) in their homes, assisted by one primary caregiver each and one community-based rehabilitation worker (CBRW). ICT observations were logged as field notes. Stakeholder perspectives were obtained through participant journals and interviews, thematically analyzed using NVIVO, and validated by participants. Facilitators and barriers were derived from data triangulation of field notes, journals, and interviews.@*RESULTS@# The best ICT comprised of fastest wireless internet available (7.2 Mbps), MacBook™ laptop, and FaceTime™ videoconferencing application. Stakeholders had varied yet positive perspectives. The SLP focused on ICT requirements and intervention conduct. The families saw telerehabilitation benefits of cost-effectiveness and intervention effectiveness. Both SLP and the families were satisfied as telerehabilitation providers and consumers. CBRW appreciated intervention effectivity. The only barrier to telerehabilitation was low internet bandwidth. Facilitators to telerehabilitation were stronger CBR policies and SLP capacity development.@*CONCLUSION@#Telerehabilitation is feasible in speech-language pathology within communitybased rehabilitation in the Philippines, given community-appropriate ICT and positive experiences of stakeholders. It can flourish with faster internet, stronger community health policies, and empowering stakeholders.

ABSTRACT
ABSTRACT OBJECTIVE To determine the seroprevalence of hepatitis B and C among immigrants residing refugee camps in Muzaffarabad, Azad Kashmir, Pakistan, and to identify possible risk factors for hepatitis B virus (HBV) and hepatitis C virus (HCV) transmission. METHODS Around 1,225 individuals inhabiting Muzaffarabad refugee camps, participated in the study. A qualitative Immuno-Chromatographic Technique was used for initial screening and PCR test was used for detection of HBV and HCV in participants. The major risk factors for HBV and HCV transmission were assessed using a questionnaire approach. RESULTS Around 86 (7.0%) individuals were observed for hepatitis B surface antigen (HBsAg) presence, and 215 (17.5%) individuals were found positive for Anti-HCV. Only 32 (2.6%) individuals were confirmed for HBV DNA and 126 (10.3%) individuals were positive for HCV RNA after PCR. Demographically, both HBsAg and Anti-HCV were found more prevalent in female (4.4% HBsAg and 10.8% Anti-HCV) population as compared to male (2.6% HBsAg and 6.7% Anti-HCV) population. Surprisingly, the HBsAg (23.5%) and Anti-HCV (41.1%) appeared to be more frequent in the age group 62-75 years. Previous history of hepatitis in the family (p < 0.0001), blood transfusion (p = 0.0197) dental treatment (p < 0.0001) and tattooing or piercing on any part of the body (p = 0.0028) were assessed as significant risk factors in HBV and HCV transmission. CONCLUSIONS Presence of 7.0% HBsAg and 17.5% Anti-HCV in a small fragment of the migrant population cannot be overlooked. Lack of awareness among people and negligence of health department could escalate the situation.

Background@#Approximately 20%–25% of high-risk gestational trophoblastic neoplasia (GTN) patients initially treated with first-line chemotherapy regimen develop resistance to the regimen. The EP-EMA (Etoposide-cisplatin and etoposide, methotrexate and actinomycin D) regimen is the most commonly utilized second-line agent. @*Objective@#This study aimed to identify factors leading to remission using etoposide and cisplatin-etoposide, methotrexate, and Actinomycin D (EP-EMA) as salvage chemotherapy among resistant high-risk GTN.@*Methods@#This is a retrospective descriptive study that reviewed the medical records of patients admitted in the section of trophoblastic diseases diagnosed with high-risk GTN from January 2006 to December 2015. @*Results@#The medical records of 20 patients were retrieved and reviewed. The complete remission rate with EP-EMA is 60% (12/20). The overall survival rate for 1 year is 70% (14/20). Only 20% of the patients went home against advice and did not complete treatment. This regimen reported toxicities ranging from Grade 2–4 myelosuppression and electrolyte imbalance. Forty-five percent had Grade 4 neutropenia and Grade 2 anemia and 20% had Grade 2 thrombocytopenia. Hypokalemia and hypomagnesemia were noted in 8 patients (40%). Although not statistically significant, a trend showed that those in the remission group mostly had Stage III diseases with metastasis only in the lungs, prognostic score of between 7 and 12, and with beta-human chorionic gonadotropin (β-hCG) levels <10,000 mIu/ml at the start of EP-EMA treatment.@*Conclusion@#There is an improved response with EP-EMA chemotherapy across the years in our institution. Factors such as stage of disease, pulmonary metastasis, and low β-hCG at the start EP-EMA chemotherapy denote a possible good response and may contribute to patients' complete remission with EP-EMA chemotherapy. However, further studies with larger patient sample size are recommended to support the latter.

ABSTRACT OBJECTIVE: This research aimed to quantitatively assess the general public's awareness, attitude and perception of polio and its vaccination in Peshawar KPK, Pakistan. METHODS: We conducted a survey-based study to understand the surge in polio cases from 2015 to 2019 in the Peshawar city of the Khyber Pakhtunkhwa (KPK), Pakistan. A pre-tested questionnaire-based study was conducted in 2019 to assess the attitude and general perception of residents of Peshawar KPK towards polio vaccination. RESULTS: Out of 241 country-wide polio cases, 63 (26.1%) polio cases were reported in Peshawar city from 2015-2019. The questionnaire revealed that individuals between 18-30 years of age had sufficient knowledge (65.1%) about polio. Male and female participants had equal awareness (~ 43%). Participants with higher education (45.9%), those with better financial status (49.5%), individuals with children < 5 years of age (46.4%), and those who had experience of a polio patient (63.1%) had better knowledge. Participants inhabiting the central city were better aware (50.5%) of polio than individuals living in the outskirts. CONCLUSION: The data indicated that poor knowledge and negative attitudes of people towards polio vaccination are the main causes of the polio eradication program's failure. Moreover, religious beliefs, unchecked migration between the Pak-Afghan border, and lack of knowledge about polio vaccination are identified as critical barriers to polio eradication.

Objective@#The therapeutic benefits of poly(ADP-ribose) polymerase inhibitors highlight the need to evaluate BRCA1/2 defects in tubal/ovarian cancer (OC). We sought to determine the pattern and disease characteristics associated with tumor BRCA1/2 mutations and BRCA1 methylation in women with OC. @*Methods@#We obtained 111 OC specimens from 2 university hospitals and assessed BRCA1/2 mutations and BRCA1 methylation in tumor DNA. The frequency and pattern of BRCA1/2 defects were examined. Associations between patient/disease characteristics and BRCA1/2 defects were ascertained (Fisher’s exact test). Platinum-free interval (PFI), progression-free survival (PFS), and overall survival (OS) based on the underlying BRCA1/2 defect were determined (Kaplan-Meier analysis [log-rank test]). @*Results@#We observed a BRCA1/2 dysfunction rate of 40% (28/70) in high-grade serous tubal/ovarian cancer (HGSC), including 14.3% BRCA1 methylation (n=10), 7.1% BRCA1 mutation (n=5), and 18.6% BRCA2 mutation (n=13). Defects in BRCA1/2 genes were associated with stage III/IV HGSC (BRCA1 methylation: P=0.005 [stage III/IV] and P=0.004 [HGSC]; BRCA1/2 mutation: P=0.03 [stage III/IV] and P<0.001 [HGSC]). Patients with BRCA1/2-mutated cancers showed improved OS (hazard ratio [HR], 0.65; 95% confidence interval [CI], 0.43–0.99; P=0.045) and a trend toward improved PFI (HR, 0.48; 95% CI, 0.22–1.06; P=0.07) and PFS (HR, 0.72; 95% CI, 0.51–1.03; P=0.07). No survival differences were observed between BRCA1-methylated and BRCA1/2 wild-type non-BRCA1-methylated cancers. @*Conclusion@#We observed a high tumor BRCA1/2 dysfunction rate in HGSC with a unique predominance of BRCA2 over BRCA1 mutations. While BRCA1/2 mutations conferred survival benefits in OC, no such association was observed with BRCA1 methylation.

ABSTRACT
Abstract The response of two local maize (Zea mays L.) genotypes designated as Sahwal-2002 (salt-tolerant) and Sadaf (salt-sensitive) to salt stress was investigated under controlled growth conditions. The role of phenylalanine and seed priming under salt stress in maize with different morphological parameters were studied. The genotype Sadaf, being salt-tolerant, experienced more oxidative damage than the Sahiwall-2002 genotype under salt stress. The salinity affected both growth and physiological attributes of the maize species whereas the phenylalanine successfully increased the salinity tolerance in maize species at the seedling stage.

Purpose: There are different learning styles adopted by medical education participants. The aim of this study was to investigate which learning styles and approaches prefer to be learning by medical students.Materials and Methods: It is a cross-sectional study, 320 students were selected through stratified random sampling. Visual, auditory, read/write, and kinesthetic (VARK) questionnaire was used which measures dimension of learning styles and approaches.Results: Among 320 participants, most of the first, second, third, fourth, and final year students had 31.93%, 32.27%, 31.83%, 32.09%, and 31.26% were in favor of kinesthetic learning, respectively, and 69% of all year students prefer multimodal approaches.Conclusion: Medical education participants commonly used kinesthetic styles and there is no difference among different years of study, but in learning approach, multimodal has increased as year of studying increased. It suggests that curriculum of medical education should be revised according to the result of research
ABSTRACT
OBJECTIVE: Depression is a prevalent condition that is costly to individuals and society. In view of a role of tryptophan (TRP), selenium (Se), vitamin D (Vit D), magnesium (Mg) and serotonin in depression, the present study concerns to evaluate the circulating levels of TRP, Se, Vit D, Mg and serotonin in depression as well as the correlation between TRP and other serum analytes is also established.METHODS: Healthy (n=48) and depressed (n=48) subjects were recruited and their blood samples were obtained after an overnight fast of 12 h, serum was stored for the determination of levels of TRP, Se, Vit D, Mg, and serotonin.RESULTS: show that levels of TRP, Se, Vit D, Mg, and serotonin were decreased in the depressed patient when compared to normal subjects. There is a direct correlation between TRP and Vit D, and TRP and Se while the inverse correlation between TRP and Mg, and TRP and serotonin in depressed subjects. The association among TRP and other biomarkers is non-significant.CONCLUSION: In conclusion, depression is associated with deficiency of TRP, Se, Vit D, Mg, and serotonin displays the characteristics of biomarkers. The correlation between TRP and other biomarkers/trace elements is also important in depression.
