velvet antlers vas are commonly used in traditional chinese medicine and invigorant and contain many PET components for health promotion the velvet antler peptide svap is one of active components in vas based on structural study the svap interacts with tgfβ receptors and disrupts the tgfβ pathway we hypothesized that svap prevents cardiac fibrosis from pressure overload by blocking tgfβ signaling SDRs underwent TAC tac or a sham operation T3 one month rats received either svap mgkgday or vehicle for an additional one month tac surgery induced significant cardiac dysfunction FB activation and fibrosis these effects were improved by treatment with svap in the heart tissue tac remarkably increased the expression of tgfβ and connective tissue growth factor ctgf ROS species C2 and the phosphorylation C2 of smad and ERK kinases erk svap inhibited the increases in reactive oxygen species C2 ctgf expression and the phosphorylation of smad and erk but not tgfβ expression in cultured cardiac fibroblasts angiotensin ii ang ii had similar effects compared to tac surgery such as increases in αsmapositive CFs and collagen synthesis svap eliminated these effects by disrupting tgfβ IB to its receptors and blocking ang iitgfβ downstream signaling these results demonstrated that svap has antifibrotic effects by blocking the tgfβ pathway in CFs

in this paper a new MM of SOC is introduced this model called the mRNA paradigm is motivated by the problem of gene expression initiation in the newlyborn daughter cells T3 mitosis the MM is fundamentally different in dynamics and properties from the well known sandpile paradigm simulation experiments demonstrate that a critical total number of proteins exists below which transcription is impossible above this critical threshold the system enters the regime of selfsustained oscillations with standard deviations and periods proportional to the genes complexities with probability one the BL between these two regimes is very sharp importantly such a selforganization emerges without any deterministic feedback loops or external supervision and is a result of CR random redistribution of proteins between inactive genes given the size of the genome the domain of selforganized oscillatory motion is also limited by the genes maximal complexities below the critical complexity all the regimes of selforganized oscillations are selfsimilar and largely independent of the genes complexities above the level of critical complexity the wholegenome transcription is impossible again the BL between the domains of oscillations and G0 is very sharp the gene expression paradigm is an example of CA with the domain of application potentially far beyond its biological context the MM seems to be simple enough for staging an experiment for verification of its remarkable properties

morphine is the preferred opioid analgesic in pediatric cancer pain due to extensive clinical experience with it significant pharmacokinetic and pharmacodynamic data following oral and parenteral administration global availability and the OD of controlledrelease formulations RCTs are needed to fully evaluate the pharmacokinetics dose equivalence clinical efficacy and safety of other opioid analgesics in CA pain PCTs are also needed to evaluate the efficacy and safety of adjuvant analgesics in children including TCAs anticonvulsants and antiarrhythmics for NP and corticosteroids and diphosphonates for bone pain unfortunately the number of children with CA pain and SD analgesic requirements is usually not C1 enough to support wellcontrolled PCTs at a single institution consequently multicentre and perhaps multinational efforts are necessary to fully evaluate opioid pharmacokinetics pharmacodynamics and dosage guidelines in children with CA

reelin is a huge secreted protein that controls proper laminar formation in the developing BB it is generally believed that IMT phosphorylation of disabled dab by src family IMT kinases is the most critical downstream event in reelin signaling the receptors for reelin belong to the low density lipoprotein receptor family most of whose members undergo regulated intracellular trafficking in this study we propose novel roles for dab in reelin signaling we first demonstrated that cell surface expression of reelin receptors was decreased in dabdeficient neurons in heterologous cells dab enhanced cell surface expression of reelin receptors and this effect was mediated by direct interaction with the receptors moreover dab did not stably associate with the receptors at the BPM in the resting state when reelin was added to primary cortical SN dab was recruited to the receptors and its tyrosine residues were phosphorylated although reelin and dab colocalized well shortly T3 the addition of reelin dab was no longer associated with internalized reelin when src family TKs were inhibited internalization of reelin was severely abrogated and reelin colocalized with dab near the BPM for a prolonged period taken together these results indicate that dab regulates both cell surface expression and internalization of reelin receptors and these regulations may play a role in correct laminar formation in the developing brain

Discussion of Biases

Since the abstracts are written in English, the data is biased towards anglo-centric medical research. If you plan to use a model pre-trained on this dataset for a predominantly non-English community, it is important to verify whether there are negative biases present in your model, and ensure that they are correctly mitigated. For instance, you could fine-tune your dataset on a multilingual medical disambiguation dataset, or collect a dataset specific to your use case.
