There is a need to evaluate the feasibility of using tests for Ct infection and anti-...

Predicting drug-target interactions using Lasso with random forest based on evolutionary information and chemical structure.

The identification of drug-target interactions has great significance for pharmaceutical scientific research. Since traditional experimental methods identifying drug-target interactions is costly and time-consuming, the use of machine learning methods to predict potential drug-target interactions has attracted widespread attention. This paper presents a novel drug-target interactions prediction me...

Degradation Rate Observations as a Function of Drug Load in Solid State Drug Products.

Degradation rates of solid state drug products generally increase as the drug load decreases. A model for quantifying this effect based on surface area ratios is proposed here. This model relates the degradation rate to an estimate of the proportion of drug substance in contact with the excipient, and that the drug substance in contact with excipients degrades more quickly. Degradation data from p...

Geraniol protects against lipopolysaccharide and D-galactosamine-induced fulminant hepatic failure by activating PPARγ.

Geraniol (GOH), a natural component of plant essential oils, exhibits potent antioxidant and anti-inflammatory properties. The aim of this study was to assess the protective effects and mechanisms of GOH on lipopolysaccharide (LPS)/d-galactosamine (D-GalN)-induced fulminant hepatic failure (FHF). Mice were treated with GOH (12.5, 25, and 50 μg/kg) 1 h before challenging LPS (60 mg/kg) and D...

Expanding the Molecular Characterization of Thoracic Inflammatory Myofibroblastic Tumors beyond ALK gene rearrangements.

Half of inflammatory myofibroblastic tumors (IMTs) regardless of anatomic location harbor ALK gene rearrangements and overexpress ALK protein. The wide application of next generation sequencing (NGS) and the clinical benefit to tyrosine kinase inhibitors have opened new opportunities for investigation of ALK-negative IMT.

Dimethyl fumarate ameliorates acetaminophen-induced hepatic injury in mice dependent of Nrf-2/HO-1 pathway.

Drug-induced liver toxicity is the most frequent cause of acute liver failure worldwide. Hepatotoxicity caused by acetaminophen (ACT) overdose is mediated by its metabolic product promoting oxidative stress and activation of inflammatory mediators. Nuclear factor erythroid-related factor-2 (Nrf-2) induces the release of cytoprotective enzymes in response to electrophilic or oxidative stress and is...

Sex-Specific Association between Prenatal Life Stress Exposure and Infant Pro-Inflammatory Cytokine Levels during Acute Respiratory Infection.

Prenatal life stress exposure is linked to dysregulated immune function and chronic inflammatory disease in offspring, but we know little about its effects on infant immune response during viral infection.

Applications of π-π stacking interactions in the design of drug-delivery systems.

Noncovalent forces are of considerable importance in the formation of self-assembled drug-delivery systems. In addition to non-destructively linking the delivery vehicle and guest drug, they provide multiple advantages, including protecting the structure of the drug, maintaining its functional effects, and facilitating its release. In particular, π-π stacking interactions have potential applicat...

Microfluidic assembly of hydrogel-based immunogenic tumor spheroids for evaluation of anticancer therapies and biomarker release.

Diffuse large B cell lymphoma (DLBCL), the most common subtype of Non-Hodgkin lymphoma, exhibits pathologic heterogeneity and a dynamic immunogenic tumor microenvironment (TME). However, the lack of preclinical in vitro models of DLBCL TME hinders optimal therapeutic screening. This study describes the development of an integrated droplet microfluidics-based platform for high-throughput generation...

Targeting STATs in neuroinflammation: the Road Less Traveled!

JAK/STAT transduction pathway is a highly conserved pathway implicated in regulating cellular proliferation, differentiation, survival and apoptosis. Dysregulation of this pathway is involved in the onset of autoimmune, haematological, oncological, metabolic and neurological diseases. Over the last few years, the research of anti-neuroinflammatory agents has gained considerable attention. The abil...

Identification of B cell epitopes enhanced by protein unfolding and aggregation.

Aggregation of therapeutic proteins is a key factor in the generation of unwanted immunogenicity, and can result in reduced serum half-life, neutralization of function and adverse health effects. There is currently little information regarding how aggregates interact with B-cell receptors or cognate antibodies at the protein sequence level, or whether non-native, aggregate-induced epitopes predomi...
