Four villages were selected where the highest population of buffaloes were found in Syria maira. The farm buffalos were kept mostly for the purpose of selling the milk Results showed that the most of the areas the buffalo keeping is for the purpose of selling the milk wile in other where the selling rate is not found they keep them for their own food and milk purposes. It facilitate their economic status to rise as a part time job. Government should take steps to rise there stander
Cross talk between serum Kisspeptin-Leptin during assisted reproduction techniques
Background & Objective: Leptin facilitates onset of puberty by impact on hypothalamic Kisspeptin, gonadotropin releasing hormone, follicle stimulating and luteinizing hormone. The link of peripheral Leptin-Kisspeptin in regulating the ovarian and endometrial tissue in relation to adiposity is unknown. Therefore, we wanted to identify Kisspeptin-Leptin association with body mass index (BMI) and success of assisted reproductive treatments (ART) in infertile females.Methods: A cross sectional study was carried from August 2014 till May 2016 after receiving ethical approval at Australian Concept Infertility Medical Centre, and Aga Khan University. The study group comprised of females with an age range of 25-37 year who had duration of unexplained infertility for more than two years. They were grouped as; underweight (/m2), normal weight (18-22.9 kg/m2), overweight 23-24.99 kg/m2 and obese (\u3e25 kg/m2). Kisspeptin and Leptin levels were measured by enzyme linked immune sorbent assay before down regulation of ovaries and initiation of treatment protocol of ART. Failure of procedure was detected by beta human chorionic gonadotropin \u3c25mIU/ml (non-pregnant) whereas females with levels \u3e25mIU/ml and cardiac activity on trans-vaginal scan were declared pregnant.Results: Highest Kisspeptin and Leptin levels were seen in normal weight group (374.80 ± 185.08ng/L; 12.78 ± 6.8 pg/ml) respectively, yet the highest number of clinical pregnancy was observed in overweight group (42%).A strong correlation of Kisspeptin with Leptin (r=0.794, p=0.001) was observed in the overweight females.Conclusion: Leptin-Kisspeptin-fertility link is expressed by maximum number of clinical pregnancies in the female group that showed strongest relationship between serum Leptin and Kisspeptin levels, irrespective of their BMI
Personalized Medicine; a Potential Therapy for Cystic Fibrosis
Cystic Fibrosis (CF) is an inherited disorder caused by mutations in CFTR gene that codes for Cystic Fibrosis Transmembrane-conductance Receptor anion channel. It is an autosomal recessive disease which affects the cells that secrete sweat, mucous and digestive juice, making these fluids thick and sticky, thus plugging ducts and tubes of various organs. The CF mutations are classified into various classes (class I, II, III, IV, V and VI) based on the cellular phenotype and complexity of mutants. The knowledge and understanding of biology and mechanisms of defects that underlie Cystic fibrosis paved a way to the development of different therapeutic approaches for these mutation classes. Ivacaftor first CFTR potentiator (FDA approved in 2012) is mostly used for Class III and IV mutations. Trials in patients with homozygous F508del mutation, a most common type of CF mutation that involves protein processing defects, showed no improvement with Ivacaftor alone, therefore, a double-combination therapy involving potentiator-corrector i.e., Ivacaftor-Lumacaftor got approval in 2015 to treat patients homozygous for F508del mutation. Then Ivacaftor-Tezacaftor (corrector) combination therapy was approved in 2018 which showed improved tolerability as compared to lumacaftor. In 2019, Trikfta, a triple combination therapy, came into light. It increases CFTR activity and is substantially considered to work more effectively in patients homozygous for F508del mutation. Studies and clinical trials reveal the outperformance of Trikafta in other available therapies in terms of respiratory symptoms, lungs functionality and quality of life on a whole.Keywords: Cystic Fibrosis (CF); Cystic Fibrosis Transmembrane Conductance regulator (CFTR); Ivacaftor; Lumacaftor; Tezacaftor; Trikafta   Â

The Impact of COVID-19 on E-Learning: Context-Based Sentiment Analysis Discourse Using Text Mining
Finding the most dominant and pertinent user opinions on a certain topic is crucial to the sentiment analysis success factor. During the pandemic lockdowns around the world, the suspension of academic institutions leads to an exceptional increase in distance education. Academic institutions closed their campuses immediately to mitigate the effects of COVID-19 and prevent its pervasive spread, and educational activities were shifted to online platforms. The effectiveness of online education is a significant topic of interest for both students and their parents, especially in terms of how students and teachers perceive it and how technologically viable it is in a range of social circumstances. Before such a wide adoption of e-learning is possible, these issues must be analyzed from multiple perspectives. The present research aims to evaluate the efficacy of e-learning by examining individuals' perceptions of it. Opinions can be found on websites such as Instagram, Facebook, Twitter, etc. As social media has recently emerged as a significant means of communication. This study addresses factors connected to a significant change in the educational system. 200,000 tweets were gathered from Twitter to evaluate the opinions of Twitter users who were taking part in online learning. This study adopts VADER to analyze the subjectivity and polarity score of tweets, a topic model was also created using the LDA algorithm to determine the themes that were talked about on Twitter the most. The models have been constructed and evaluated using Word2Vec to capture the semantic relationships between words and LSTM and RNN sequential model for sentiment analysis. This study measured the efficiency of a sentiment analysis model using the accuracy metric, the conducted experiments reveal that the proposed hybrid model achieves an overall accuracy of 96.3%. The results also indicate a significant negative impact of the Covid-19 pandemic on individuals' emotions, with 64.4% of the analyzed tweets displaying negative sentiments. These findings provide valuable insights into the relationship between global events and individual emotions on social media platforms
Recent Advances in Applications of Acidophilic Fungi to Produce Chemicals
Processing of fossil fuels is the major environmental issue today. Biomass utilization for the production of chemicals presents an alternative to simple energy generation by burning. Lignocellulosic biomass (cellulose, hemicellulose and lignin) is abundant and has been used for variety of purposes. Among them, lignin polymer having phenyl-propanoid subunits linked together either through C-C bonds or ether linkages can produce chemicals. It can be depolymerized by fungi using their enzyme machinery (laccases and peroxidases). Both acetic acid and formic acid production by certain fungi contribute significantly to lignin depolymerization. Fungal natural organic acids production is thought to have many key roles in nature depending upon the type of fungi producing them. Biological conversion of lignocellulosic biomass is beneficial over physiochemical processes. Laccases, copper containing proteins oxidize a broad spectrum of inorganic as well as organic compounds but most specifically phenolic compounds by radical catalyzed mechanism. Similarly, lignin peroxidases (LiP), heme containing proteins perform a vital part in oxidizing a wide variety of aromatic compounds with H2O2. Lignin depolymerization yields value-added compounds, the important ones are aromatics and phenols as well as certain polymers like polyurethane and carbon fibers. Thus, this review will provide a concept that biological modifications of lignin using acidophilic fungi can generate certain value added and environmentally friendly chemicals
