Predicting depression intensity from microblogs and social media posts has numerous benefits and applications,including predicting early psychological disorders and stress in individuals or the general public.A major challenge in predicting depression using social media posts is that the existing studies do not focus on predicting the intensity of depression in social media texts but rather only perform the binary classification of depression and moreover noisy data makes it difficult to predict the true depression in the social media *** study intends to begin by collecting relevant Tweets and generating a corpus of 210000 public tweets using Twitter public application programming interfaces(APis).A strategy is devised to filter out only depression-related tweets by creating a list of relevant hashtags to reduce noise in the ***,an algorithm is developed to annotate the data into three depression classes:‘Mild,’‘Moderate,’and‘severe,’based on international Classification of Diseases-10(iCD-10)depression diagnostic *** baseline classifiers are applied to the annotated dataset to get a preliminary idea of classification performance on the *** FastText-based model is applied and fine-tuned with different preprocessing techniques and hyperparameter tuning to produce the tuned model,which significantly increases the depression classification performance to an 84%F1 score and 90%accuracy compared to ***,a FastText-based weighted soft voting ensemble(WsVE)is proposed to boost the model’s performance by combining several other classifiers and assigning weights to individual models according to their individual *** proposed WsVE outperformed all baselines as well as FastText alone,with an F1 of 89%,5%higher than FastText alone,and an accuracy of 93%,3%higher than FastText *** proposed model better captures the contextual features of the relatively small sample class and aids in the detection of

Glutamine and glutamate supplementation raise milk glutamine concentrations in lactating gilts

Journal of Animal science and Biotechnology 2012年第1期3卷 25-31页

作者： helena Emilia CCC Manso Helio C Manso Filho Luiz E de Carvalho Marianne Kutschenko Eduardo T nogueira Malcolm Watford Department of Animal sciences Rural Federal University of PernambucoRecifePE52171-900Brazil Departament of Animal sciences Federal University of CearáFortalezaCE60020-181Brazil Ajinomoto do Brazil S oPauloSP04015-001Brazil Department of Nutritional sciences Rutgers UniversityNew BrunswickNJ08901USA.

Glutamine is the most abundant amino acid in milk, and lactation is associated with increased glutamine utilization both for milk synthesis and as a fuel for the enlarged small intestine. A number of recent studies have indicated that lactation is accompanied by a mild catabolic state in which skeletal muscle proteins are degraded to provide amino acids that are used to synthesize additional glutamine. in this study we tested the hypothesis that supplemental L-glutamine or the commercially available glutamine supplement Aminogut （2.5% by weight mixed into daily feed） provided to gilts from 30 days prior to parturition until 21 days post-parturition would prevent a decrease in skeletal muscle glutamine while increasing the glutamine content of the milk. Muscle glutamine content decreased （P 〈 0.05） in control animals during lactation but this was prevented by supplementation with either L-glutamine or Aminogut. in this study, neither lactation nor supplementation had any effect on plasma glutamine or glutamate content. Free glutamine, and the total glutamine plus glutamate concentrations in milk from the control and the Aminogut group rose （P 〈 0.05） during the first 7 days of lactation, with milk concentrations in the L-glutamine supplemented group showing a similar trend （P = 0.053）. Milk glutamate remained constant between day 7 and 21 of lactation in the control and L-glutamine supplemented groups, but by day 21 of lactation the free glutamine, glutamate, and glutamine plus glutamate concentrations in milk from Aminogut-treated gilts were higher than those of control gilts. Thus dietary glutamine supplementation can alleviate the fall in intramuscular glutamine content during lactation in gilts, and may alleviate some of the catabolic effects of lactation. Furthermore, the increased milk glutamine content in the supplemented gilts may provide optimum nutrition for piglet development.

The functional significance of dentin sialoprotein-phosphophoryn and dentin sialoprotein

引用

international Journal of Oral science 2018年第4期10卷 197-202页

作者： helena Ritchie Department of Cariology Restorative Sciences and EndodonticsUniversity of Michigan School of Dentistry

Phosphophoryn (PP) and dentin sialoprotein (DsP) are the most dominant non-collagenous proteins in dentin. PP is an extremely acidic protein that can function as a mineral nucleator for dentin mineralization. DsP was first identified in 1981, yet its functional significance is still controversial. Historically, these two proteins were considered to be independently synthesized and secreted by dental pulp cells into the developing dentin matrix. However, with the identification of the DsP coding sequence in 1994, followed2 years later by the finding that the PP coding sequence was located immediately downstream from the DsP sequence, it became immediately clear that DsP and PP proteins were derived from a single DsP-PP (i.e., dentin sialophosphoprotein, DsPP) *** DsPP cDNA became available, tremendous progress has been made in studying DsP-PP mRNA distribution and DsP generation from the DsP-PP precursor protein at specific cleavage sites by protease tolloid-related-1 (TLR1) or bone morphogenetic protein 1 (BMP1). The functions of DsP-PP and DsP were investigated via DsP-PP knockout (KO) and DsP knockin in DsP-PP KO mice. in addition, a number of in vitro studies aimed to elucidate DsPP and DsP function in dental pulp cells.
