Recent studies indicate that extracellular vesicles are an important source material for many clinical applications, including minimally-invasive disease diagnosis. However, challenges rapid and simple vesicle collection have hindered their application. We developed validated a novel class of peptides (which we named venceremin, or Vn) exhibit nucleotide-independent specific affinity canonical heat shock proteins. The Vn were to specifically efficiently capture HSP-containing from cell...
Multimodal AI models are increasingly used in fields like healthcare, finance, and autonomous driving, where information is drawn from multiple sources or modalities such as images, texts, audios, videos. However, effectively managing uncertainty - arising noise, insufficient evidence, conflicts between crucial for reliable decision-making. Current uncertainty-aware ML methods leveraging, example, evidence averaging, accumulation underestimate uncertainties high-conflict scenarios. Moreover,...
Recurrent apneas are important causes of hospitalization and morbidity in newborns. Gestational stress (GS) compromises fetal brain development. Maternal anxiety during gestation linked to respiratory disorders newborns; however, the mechanisms remain unknown. Here, we tested hypothesis that repeated activation neuroendocrine response is sufficient disrupt development control augment occurrence newborn rats. Pregnant dams were displaced exposed predator odor from days 9 19 gestation. Control...
Abstract PAX5 and EBF1 work synergistically to regulate genes that are involved in B lymphocyte differentiation. We used the KIS-1 diffuse large cell lymphoma line, which is reported have elevated levels of expression, investigate mechanism EBF1- PAX5-regulated gene expression. demonstrate lack expression hallmark genes, including CD19 , CD79b line. Upon restoration we observed activation other with critical roles Mass spectrometry analyses proteins co-immunoprecipitated identified...
Perinatal stress disrupts normal development of the hypothalamo‐pituitary‐adrenal (HPA) axis. Adult male (but not female) rats previously subjected to a such as neonatal maternal separation (NMS) are characterized by chronic elevation plasma corticosterone (Cort) levels and an abnormally elevated hypoxic ventilatory response through mechanisms that remain unknown. The present study tested hypothesis increase Cort alone augments hypoxia in adult rats. Three groups Sprague–Dawley female were...
Human and animal studies on sleep-disordered breathing respiratory regulation show that the effects of sex hormones are heterogeneous. Because neonatal stress results in sex-specific disruption control adult rats, we postulate it might affect modulation induced by ovarian steroids female rats. The hypoxic ventilatory response (HVR) rats exposed to maternal separation (NMS) is ∼30% smaller than controls (24), but consequences NMS aging unknown. To address this issue, whole body...
Subjectivity is a key aspect of natural language understanding, especially in the context user-generated text and conversational systems based on large models. Natural sentences often contain subjective elements, such as opinions emotions, that make them more nuanced complex. The level detail at which study performed determines possible applications sentiment analysis. analysis can be done document or paragraph level, or, even granularly, level. Many researchers have studied this topic...
“Extreme” housing conditions, such as isolation (single housing) or crowding, are stressful for rats, and their deleterious impact on behavior is well documented. To determine whether more subtle variations in can affect animal physiology, the present study tested hypothesis that hypoxic ventilatory response (HVR) of adult male rats housed pairs during juvenile period (postnatal day 21 to adulthood) does not differ from animals triads. Because neonatal stress augments neuroendocrine...
In this paper, we present our contribution in SemEval2016 task7 1 : Determining Sentiment Intensity of English and Arabic Phrases, where use web search engines for unsupervised sentiment intensity prediction.Our work is based, first, on a group classic lexicons (e.g.Sen-timent140 Lexicon, SentiWordNet).Second, engines' ability to find the cooccurrence sentences with predefined negative positive words.The (e.g.Google Search API) enhance results phrases built from opposite polarity terms.
Neonatal stress disrupts development of homeostatic systems. During adulthood, male rats subjected to neonatal maternal separation (NMS) are hypertensive and show a larger hypoxic ventilatory response (HVR), with greater respiratory instability during sleep. also affects sex hormone secretion; hypoxia increases circulating testosterone NMS (but not control) rats. Given that these effects observed in females, we tested the hypothesis elevation is necessary for stress-related increase HVR...
We present, in this paper, our contribution SemEval2017 task 4 : “Sentiment Analysis Twitter”, subtask A: “Message Polarity Classification”, for English and Arabic languages. Our system is based on a list of sentiment seed words adapted tweets. The relations between other terms are captured by cosine similarity the word embedding representations (word2vec). These extracted from datasets annotated tweets available online. tests, using these words, show significant improvement results compared...
The feasibility of a solar-powered hybrid airship where lift is generated by both buoyancy and aerodynamics investigated using aerodynamic shape optimization. design objective to minimize the product envelope root chord span (which corresponds size hangar required house airship), subject constraints on lift, ratio solar power produced consumed, operational empty weight, trim, static margin. Simple mass models are used estimate components, including array, drive train fabric. optimizer has...
Book search is a challenging task due to discrepancies between the content and description of books, on one side, ways in which people query for other. However, online reviewers provide an opinionated book, with alternative features that describe emotional experiential aspects book. Therefore, locating sentences within reviews, could rich source evidence help improve book recommendations. Specifically, sentiment analysis (SA) be employed identify salient terms, then used expansion? This...
Résumé Ce travail vise à renouveler l’approche des pratiques festives et de loisir dans les sociétés occidentales contemporaines. En dépassant l’opposition classique qui valorisait une rupture entre temps la fête quotidien, il interroge d’abord notions d’événement loisir. L’analyse fêtes comme révélatrices conceptions spécifiques du l’espace permet ensuite repérer d’essayer d’articuler elles plusieurs caractéristiques fonctions actuelles: rapprochées loisirs, marchandisées standardisées mais...
Due to Web size and diversity of information, relevant information gathering on the is a very complex task. The main problem with most retrieval approaches neglecting context pages, mainly because search engines are based keyword indexing. Considering restricted domain, policy taking into account may lead more in this paper, specific cooperative approach use software agents ontologies proposed. To implement approach, generic architecture, named AGATHE system, early prototype, MASTER-Web...
