Determination of Nutritional and Biochemical Composition of Selected Pleurotus spps.

The global demand for good quality food is going to be increased gradually. Mushrooms are broadly used as healthy nutritious meals. The nutritional values of extracts from four distinct Pleurotus species-Pleurotus ostreatus, Pleurotus sajor-caju, Pleurotus sapidus, and Pleurotus columbinus-were determined in the current study. Firstly, proximate analysis of selected Pleurotus species was performed followed by the Bradford assay to analyze the protein spectrophotometrically; high-performance liquid chromatography (HPLC) was performed for sugar determination while GC-MS was done to determine fatty acids on organic extracts of selected mushrooms. Descriptive statistics were used to calculate the percentages while significance was determined by SPSS statistics. The results depicted that fat, protein, ash, fiber, energy contents, and total carbohydrate were in the range of 0.64-2.02%, 16.07-25.15%, 2.1-9.14%, 6.21-54.12%, 342.20-394.30 kcal/100 g, and 65.66-82.47%, respectively. The protein's maximum concentration was observed in P. ostreatus followed by P. columbinus>P. sajor-caju>P. sapidus, sequentially. Various sugars may or may not be present in selected Pleurotus spps. Among the fatty acids, the prevalence of UFA was more than that of saturated fatty acids among all selected mushrooms. From this study, it is concluded that all four Pleurotus spps. have excellent nutritional composition and can be used as valuable food and a great source of biochemical compounds.

Breast cancer knowledge among health professionals: A pre-post-knowledge-based intervention study.

Introduction: Breast-cancer-related morbidity and mortality can be reduced by following worldwide-accepted screening guidelines and by appropriate education and training of health professionals on risk identification and screening. The study aimed to determine the significance of educational sessions in improving health professionals' knowledge about breast cancer, particularly screening modalities that can benefit the patients. Method and Materials: An interventional study was conducted among 260 health professionals, including medical students, nurses, and allied health professionals. The intervention was an educational session on breast cancer risks and screening guidelines. Health professionals' knowledge about breast cancer risk, presentation, and screening were tested by a structured questionnaire before and after the educational session. Data were analyzed using Statistical Package for the Social Sciences 26. Chi-square was used to identify differences in pre and post-test. P value was considered significant at <0.05. Results: There is a significant difference between pre-session and post-session responses in all areas of knowledge about breast cancer, with much improved outcomes after the educational session. Conclusion: Health professionals lack knowledge about breast cancer risk factors, screening tools, presentation, and management. Regular education sessions improve these knowledge gaps and help early detection and treatment of women at risk of breast cancer.

Association of Viruses in the Development of Cardiovascular Diseases.

Cardiovascular diseases (CVD), primarily inflammatory cardiomyopathy, are characterized by the infiltration of inflammatory cells into the myocardium. It has a relatively high risk of deteriorating heart function and has heterogeneous etiologies. Inflammatory cardiomyopathy is mainly mediated by viral infections but can also be mediated by protozoa, fungal or bacterial infections. Besides that, there are a wide variety of drugs, toxic substances, and systemic immune-mediated diseases that result in the development of cardiovascular diseases (CVDs). Despite broad research, inflammatory cardiomyopathy has a poor prognosis. The roles of the pathogens, host genomic counterparts and environmental triggers in the progression of disease are still under consideration, including the role of some viruses as active inducers and others as bystanders. In this review article, we review the available evidence on the types, pathogenesis and treatment of myocarditis, inflammatory cardiomyopathy, and atherosclerosis with a particular focus on virus-associated cardiac diseases.

A study to observe the effects of physiotherapy with and without manual therapy in the management postural neck pain: A randomized control trial.

OBJECTIVE: To compare the effects of physiotherapy with and without manual therapy in the management of postural neck pain. METHODS: The randomised controlled trial was conducted at the Physiotherapy Department of South City Hospital, Karachi, from September 2017 to July 2018, and comprised subjects with >6 months of neck pain with no related medical dysfunction. The patients were enrolled by non-probability consecutive sampling technique and randomly divided into Group A and Group B using computer-generated numbers. Group A received physiotherapy along with manual therapy, while Group B only had physiotherapy. Group A was also taught a home exercise programme. A printed exercise sheet was provided with frequency and repetition details. Visual analogue scale for pain intensity level and neck disability index were used to measure outcome at 3rd and 12th week. Data was analysed using SPSS 22. RESULTS: Of the 60 subjects, there were 30(50%) in each of the two groups. The mean age in Group A was 32.77±7.44 years and it was 32.53±7.9 years in Group B. Overall, there were 21(35%) males and 39(65%) females. Significant reduction in pain intensity and neck disability levels at 3 and 12 weeks was noted compared to baseline (p<0.05). Inter-group comparison at final follow-up showed better Group A results compared to Group B (p<0.05). CONCLUSIONS: Physiotherapy with manual therapy was found to be better compared to physiotherapy alone.

Assessing universality of DNA barcoding in geographically isolated selected desert medicinal species of Fabaceae and Poaceae.

In pursuit of developing fast and accurate species-level molecular identification methods, we tested six DNA barcodes, namely ITS2, matK, rbcLa, ITS2+matK, ITS2+rbcLa, matK+rbcLa and ITS2+matK+rbcLa, for their capacity to identify frequently consumed but geographically isolated medicinal species of Fabaceae and Poaceae indigenous to the desert of Cholistan. Data were analysed by BLASTn sequence similarity, pairwise sequence divergence in TAXONDNA, and phylogenetic (neighbour-joining and maximum-likelihood trees) methods. Comparison of six barcode regions showed that ITS2 has the highest number of variable sites (209/360) for tested Fabaceae and (106/365) Poaceae species, the highest species-level identification (40%) in BLASTn procedure, distinct DNA barcoding gap, 100% correct species identification in BM and BCM functions of TAXONDNA, and clear cladding pattern with high nodal support in phylogenetic trees in both families. ITS2+matK+rbcLa followed ITS2 in its species-level identification capacity. The study was concluded with advocating the DNA barcoding as an effective tool for species identification and ITS2 as the best barcode region in identifying medicinal species of Fabaceae and Poaceae. Current research has practical implementation potential in the fields of pharmaco-vigilance, trade of medicinal plants and biodiversity conservation.

Comparative sequence analysis of citrate synthase and 18S ribosomal DNA from a wild and mutant strains of Aspergillus niger with various fungi.

UNLABELLED: A mutation was induced in Aspergillus niger wild strain using ethidium bromide resulting in enhanced expression of citric acid by three folds and 112.42 mg/mL citric acid was produced under optimum conditions with 121.84 mg/mL of sugar utilization. Dendograms of 18S rDNA and citrate synthase from different fungi including sample strains were made to assess homology among different fungi and to study the correlation of citrate synthase gene with evolution of fungi. Subsequent comparative sequence analysis revealed strangeness between the citrate synthase and 18S rDNA phylogenetic trees. Furthermore, the citrate synthase movement suggests that the use of traditional marker molecule of 18S rDNA gives misleading information about the evolution of citrate synthase in different fungi as it has shown that citrate synthase gene transferred independently among different fungi having no evolutionary relationships. Random amplified polymorphic DNA (RAPD-PCR) analysis was also employed to study genetic variation between wild and mutant strains of A. niger and only 71.43% similarity was found between both the genomes. Keeping in view the importance of citric acid as a necessary constituent of various food preparations, synthetic biodegradable detergents and pharmaceuticals the enhanced production of citric acid by mutant derivative might provide significant boost in commercial scale viability of this useful product.
