Study of total seed storage protein in indigenous Brassica species based on sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE)

Genetic diversity was studied in 234 accessions of locally collected Brassica species for total seed protein content through sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). These accessions were collected from different locations of Pakistan. After the study of these accessions on SDS-PAGE, 28 reproducible bands were used for cluster analysis and with the help of these bands, genetic diversity were estimated. Out of 28, four major bands were observed. Dendogram was constructed and the accessions were divided into two main groups comprising 11 clusters. The results obtained from these clusters showed minimum genetic diversity in these accessions on SDS-PAGE level. Due to low genetic diversity on SDS-PAGE level, it is suggested that two dimensional (2D)- electrophoresis can be used for protein study.Key words: Genetic variation, sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE), protein electrophoresis, cluster analysis, brassica

Kaempferol: a key emphasis to its anticancer potential

A marked decrease in human cancers, including breast cancer, bone cancer, and cervical cancer, has been linked to the consumption of vegetable and fruit, and the corresponding chemoprotective e ect has been associated with the presence of several active molecules, such as kaempferol. Kaempferol is a major flavonoid aglycone found in many natural products, such as beans, bee pollen, broccoli, cabbage, capers, cauliflower, chia seeds, chives, cumin, moringa leaves, endive, fennel, and garlic. Kaempferol displays several pharmacological properties, among them antimicrobial, anti-inflammatory, antioxidant, antitumor, cardioprotective, neuroprotective, and antidiabetic activities, and is being applied in cancer chemotherapy. Specifically, kaempferol-rich food has been linked to a decrease in the risk of developing some types of cancers, including skin, liver, and colon. The mechanisms of action include apoptosis, cell cycle arrest at the G2/M phase, downregulation of epithelial-mesenchymal transition (EMT)-related markers, and phosphoinositide 3-kinase/protein kinase B signaling pathways. In this sense, this article reviews data from experimental studies that investigated the links between kaempferol and kaempferol-rich food intake and cancer prevention. Even though growing evidence supports the use of kaempferol for cancer prevention, further preclinical and clinical investigations using kaempferol or kaempferol-rich foods are of pivotal importance before any public health recommendation or formulation using kaempferol.info:eu-repo/semantics/publishedVersio

Exploiting the Genomic Diversity of Rice (Oryza sativa L.): SNP-Typing in 11 Early-Backcross Introgression-Breeding Populations

This study demonstrates genotyping-by-sequencing-based single-nucleotide polymorphism (SNP)-typing in 11 early-backcross introgression populations of rice (at BC1F5), comprising a set of 564 diverse introgression lines and 12 parents. Sequencing using 10 Ion Proton runs generated a total of ∼943.4 million raw reads, out of which ∼881.6 million reads remained after trimming for low-quality bases. After alignment, 794,297 polymorphic SNPs were identified, and filtering resulted in LMD50 SNPs (low missing data, with each SNP, genotyped in at least 50% of the samples) for each sub-population. Every data point was supported by actual sequencing data without any imputation, eliminating imputation-induced errors in SNP calling. Genotyping substantiated the impacts of novel breeding strategy revealing: (a) the donor introgression patterns in ILs were characteristic with variable introgression frequency in different genomic regions, attributed mainly to stringent selection under abiotic stress and (b) considerably lower heterozygosity was observed in ILs. Functional annotation revealed 426 non-synonymous deleterious SNPs present in 102 loci with a range of 1–4 SNPs per locus and 120 novel SNPs. SNP-typing this diversity panel will further assist in the development of markers supporting genomic applications in molecular breeding programs

Clinicians', patients' and carers' perspectives on borderline personality disorder in Pakistan: A mixed methods study protocol

Borderline Personality Disorder (BPD) is a condition characterised by significant social and occupational impairment and high rates of suicide. In high income countries, mental health professionals carry negative attitudes towards patients with BPD, find it difficult to work with patients with BPD, and even avoid seeing these patients. Negative attitudes and stigma can cause patients to fear mistreatment by health care providers and create additional barriers to care. Patients' self-stigma and illness understanding BPD also affects treatment engagement and outcomes; better knowledge about mental illness predicts intentions to seek care. The perspectives of mental health clinicians and patients on BPD have not been researched in the Pakistani setting and likely differ from other settings due to economic, cultural, and health care system differences. Our study aims to understand the attitudes of mental health clinicians towards patients with BPD in Pakistan using a self-report survey. We also aim to explore explanatory models of illness in individuals with BPD and their family members/carers using a Short Explanatory Model Interview (SEMI). The results of this study are important as we know attitudes and illness understanding greatly impact care. Results of this study will help guide BPD-specific training for mental health clinicians who care for patients with BPD and help inform approaches to interventions for patients with BPD in Pakistan
