Objective During cardiovascular disease progression, molecular systems of myocardium (e.g., a proteome) undergo diverse and distinct changes. Dynamic, temporally-regulated alterations of individual molecules underlie the collective response of the heart to pathological drivers and the ultimate development of pathogenesis. Advances in high-throughput omics technologies have enabled cost-effective, temporal profiling of targeted systems in animal models of human diseases. However, computational analysis of temporal patterns from omics data remains challenging. see more In particular, bioinformatic pipelines involving unsupervised statistical approaches to support cardiovascular investigations are lacking, which hinders one's ability to extract biomedical insights from these complex datasets. Approach and results We developed a non-parametric data analysis platform to resolve computational challenges unique to temporal omics datasets. Our platform consists of three modules. Module I preprocesses the temporal data using eal insights underlying O-PTM regulations in cardiac remodeling. This platform is implemented in an open source R package (https//github.com/UCLA-BD2K/CV.Signature.TCP).Accurate identification and measurement of antipsychotic drugs in in-vivo and in-vitro environment has a key role in the development and design of drugs, as any slight change in their dosage can affect the treatment process. Determination of antipsychotics in physiological fluids such as blood, plasma and urine are important in drug tablets and medical approaches. Chromatography is the main method used in the determination of antipsychotic drugs but this technique, despite its relative sensitivity, is a costly and complicated method. Biosensors, as simple, low-cost and highly sensitive and specific tools, can be the best alternative to eliminate the drawbacks of routine methods. For this purpose, various biosensors have been extensively developed in the recent years. The main objective of the present study is to introduce and collect recently developed biosensors for the measurement and detection of antipsychotic drugs. Therapeutic drug monitoring (TDM) is a fundamental principle in pharmaceuticals, with the primary goal being to reduce and eliminate the side effects of drugs. This study shows that biosensors can be a modern and novel approach in the field of TDM.Introduction Interesting results regarding the contribution of MDW (Monocyte Distribution Width) in the Infectious Disease Unit have been reported. An observational study is ongoing at San Donato Hospital with the aim to evaluate the contribution of MDW in the diagnostic pathway in adult patients entering in the ED setting and tested for SARS-CoV-2. Material and method COVID-19 symptomatic and paucisymptomatic patients presenting to ED (Emergency Department), have been enrolled consecutively. Whole blood venous samples have been collected on K2 EDTA for MDW determination, at the same time a nasopharyngeal swab for SARS-CoV-2 RNA detection have been collected. Results One hundred six patients were negative for SARS-CoV-2 with MDW mean value of 20.3 ± 3.3, while forty-one were positive for SARS-CoV-2 with higher MDW mean value of 27.3 ± 4.9 (P less then 0.005). The ROC curve analysis has been evaluated showing MDW AUC of 0.91. Finally twenty-three patients hospitalized in high-intensity care unit showed an MDW value higher than the eighteen patients presenting few symptoms [28.8 ± 5.3 vs 25.4 ± 3.6 respectively, P less then 0.05]. Discussion Monocytic population, in Covid19 disease, are the first elements of innate immunity to be involved, these changes are the basis of the modification of the MDW, with evident efficacy in term of sensitivity, particularly in the studied Covid19 patients. Moreover the patients hospitalized in high-intensity care unit showed significantly elevated MDW respects to middle or low symptomatic one, suggest including this parameter as prognostic marker or of therapy efficacy, integrated with other laboratory findings.In the adult brain, self-renewing radial-glia like (RGL) progenitor cells have been shown to reside in the subventricular zone and the subgranular zone of the hippocampus. A large body of evidence shows that experiences such as learning, enriched environment and stress can alter proliferation and differentiation of RGL progenitor cells. The progenitor cells present in the subgranular zone of the hippocampus divide to give rise to newborn neurons that migrate to the dentate gyrus where they differentiate into adult granule neurons. These newborn neurons have been found to have a unique role in certain types of hippocampus-dependent learning and memory, including goal-directed behaviors that require pattern separation. Experimental traumatic brain injury (TBI) in rodents has been shown to alter hippocampal neurogenesis, including triggering the acute loss of newborn neurons, as well as progenitor cell hyper-proliferation. In this review, we discuss the role of hippocampal neurogenesis in learning and memory. Furthermore, we review evidence for the molecular mechanisms that contribute to newborn neuron loss, as well as increased progenitor cell proliferation after TBI. Finally, we discuss strategies aimed at enhancing neurogenesis after TBI and their possible therapeutic benefits.Genetic variants causing the fast-channel congenital myasthenic syndrome (CMS) have been identified in the α, δ, and ε but not the β subunit of acetylcholine receptor (AChR). A 16-year-old girl with severe myasthenia had low-amplitude and fast-decaying miniature endplate potentials. Mutation analysis revealed two heteroallelic variants in CHRNB1 encoding the AChR β subunit a novel c.812C>T (p.P248L) variant in M1-M2 linker (p.P271L in HGVS nomenclature), and a ~430 bp deletion causing loss of exon 8 leading to frame-shift and a premature stop codon (p.G251Dfs*21). P248 is conserved in all β subunits of different species, but not in other AChR subunits. Measurements of radio-labeled α-bungarotoxin binding show that βP248L reduces AChR expression to 60% of wild-type. Patch clamp recordings of ACh-elicited single channel currents demonstrate that βP248L shortens channel opening bursts from 3.3 ms to 1.2 ms, and kinetic analyses predict that the decay of the synaptic response is accelerated 2.4-fold due to reduced probability of channel reopening.
