Best of both worlds: An expansion of the state of the art pK model with data from three industrial partners.

In a unique collaboration between Simulations Plus and several industrial partners, we were able to develop a new version 11.0 of the previously published in silico pK model, S+pKa, with considerably improved prediction accuracy. The model's training set was vastly expanded by large amounts of experimental data obtained from F.

Southbound - the southernmost record of (Amphibia, Caudata, Salamandridae) from the Central Highlands of Vietnam represents a new species.

A new species of the genus is described from Ngoc Linh Mountain, Kon Tum Province, in the Central Highlands of Vietnam based on integrative taxonomy, namely by combining molecular and morphological evidence. differs from all other congeners based on morphological data, allopatric distribution, and molecular divergence. In terms of genetic divergence, distinctly differs from the sister species (6.

A new species of Vietnamophryne (Anura: Microhylidae) from Northeastern Vietnam.

A new species of the genus Vietnamophryne is described from Vietnam on the basis of two specimens collected from Tuyen Quang Province, Northeastern Vietnam. The new species is morphologically most similar to Vietnamophryne occidentalis from Thailand, however, it differs from the latter by having large black blotches in the lower jaw region, and a yellow-orange chest and belly. The genetic distance between the new species and other Vietnamophryne taxa is > 2.

Overlapping Stevens-Johnson Syndrome and DRESS Syndrome Caused by Phenobarbital: A Vietnamese Case Report.

Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) Syndrome and Stevens-Johnson Syndrome (SJS) are severe cutaneous adverse reactions to drugs. Those reactions which are rare in children can be especially severe and challenging to diagnose and manage. Herein we present a 59-month-old male who presented with a rash, fever, and multiple organ dysfunction initiation of Phenobarbital for epilepsy.

Plastic Waste: Challenges and Opportunities to Mitigate Pollution and Effective Management.

The present world is now facing the challenge of proper management and resource recovery of the enormous amount of plastic waste. Lack of technical skills for managing hazardous waste, insufficient infrastructure development for recycling and recovery, and above all, lack of awareness of the rules and regulations are the key factors behind this massive pile of plastic waste. The severity of plastic pollution exerts an adverse effect on the environment and total ecosystem.

Current scenario and challenges of plastic pollution in Bangladesh: a focus on farmlands and terrestrial ecosystems.

Plastic is considered one of the most indispensable commodities in our daily life. At the end of life, the huge ever-growing pile of plastic waste (PW) causes serious concerns for our environment, including agricultural farmlands, groundwater quality, marine and land ecosystems, food toxicity and human health hazards. Lack of proper infrastructure, financial backup, and technological advancement turn this hazardous waste plastic management into a serious threat to developing countries, especially for Bangladesh.

Dual roles of oxostephanine as an Aurora kinase inhibitor and angiogenesis suppressor.

The Aurora kinases, including Aurora A, B and C, play critical roles in cell division. They have been found overexpressed in a number of types of cancer and may thus be potential targets in cancer therapy. Several Aurora kinase inhibitors have been identified and developed.

Will previous palliative surgery for congenital heart disease be detrimental to subsequent pig heart xenotransplantation?

Introduction: Pig heart xenotransplantation might act as a bridge in infants with complex congenital heart disease (CHD) until a deceased human donor heart becomes available. Infants develop antibodies to wild-type (WT, i.e.

Amolops caelumnoctis Rao amp; Wilkinson, 2007, a Junior Synonym of A. splendissimus Orlov amp; Ho, 2007 (Amphibia: Anura: Ranidae).

Amolops splendissimus Orlov and Ho, 2007 and A. caelumnoctis Rao and Wilkinson, 2007 were described almost simultaneously from either side of the China-Vietnam border. The two species share a strong morphological resemblance, and their taxonomic distinctiveness has been questioned, yet no one has confirmed the taxonomic relationship and status between the two taxa.

Anti-pig IgE and IgA Antibodies in Naive Primates and Nonhuman Primates With Pig Xenografts.

Background: Natural preformed anti-pig IgM/IgG antibodies in primates play an important role in xenograft rejection. As it is not clear how IgE and IgA engage in the immune system in xenotransplantation, we investigated natural preformed and elicited anti-pig IgE/IgA in naive primates and after xenotransplantation in nonhuman primates.

Methods: The binding of IgM/IgG/IgE/IgA antibodies to red blood cells (RBCs) from wild-type (WT), α1,3-galactosyltransferase gene-knockout (GTKO), and GTKO/cytidine monophospho-N-acetylneuraminic acid hydroxylase gene-knockout/β-1,4 N-acetylgalactosaminyltransferase 2 gene-knockout (ie, triple-knockout pigs) pigs were measured by flow cytometry in naive human (n = 50) and baboon (n = 14) sera.

Evidence for GTKO/β4GalNT2KO Pigs as the Preferred Organ-source for Old World Nonhuman Primates as a Preclinical Model of Xenotransplantation.

Background: Triple-knockout (TKO) pigs (in which expression of the 3 known pig carbohydrate xenoantigens has been deleted) are likely to be an optimal source of organs for transplantation into human recipients, many of whom do not have natural antibodies against TKO pig cells. However, old world monkeys, for example, baboons, have natural antibodies directed to TKO cells (to a "fourth" xenoantigen that is exposed after TKO).

Methods: We measured (1) anti-pig IgM/IgG binding, and (2) complement-dependent cytotoxicity (CDC), by flow cytometry to α1,3-galactosyltransfearse gene-knockout (GTKO), GTKO/β4GalNT2KO (that do express the "fourth" xenoantigen), and TKO pig peripheral blood mononuclear cells (PBMCs) using 72 baboon sera (30 specific pathogen-free [SPF], and 42 non-SPF baboons).

Lipid droplets can promote drug accumulation and activation.

Genetic screens in cultured human cells represent a powerful unbiased strategy to identify cellular pathways that determine drug efficacy, providing critical information for clinical development. We used insertional mutagenesis-based screens in haploid cells to identify genes required for the sensitivity to lasonolide A (LasA), a macrolide derived from a marine sponge that kills certain types of cancer cells at low nanomolar concentrations. Our screens converged on a single gene, LDAH, encoding a member of the metabolite serine hydrolase family that is localized on the surface of lipid droplets.

Human CTLA4-Ig therapy can give false-positive anti-pig antibody results in primates after xenotransplantation.

Background: Measurement of serum anti-pig antibodies is an important parameter in immune monitoring after pig-to-nonhuman primate xenotransplantation. Pig aortic endothelial cells (pAECs) are commonly used for this purpose. However, human (h) CTLA4-Ig (abatacept/belatacept) could bind to pCD80/86 on the cells, and a secondary antibody (i.

Quantitative mapping of protein-peptide affinity landscapes using spectrally encoded beads.

Transient, regulated binding of globular protein domains to Short Linear Motifs (SLiMs) in disordered regions of other proteins drives cellular signaling. Mapping the energy landscapes of these interactions is essential for deciphering and perturbing signaling networks but is challenging due to their weak affinities. We present a powerful technology (MRBLE-pep) that simultaneously quantifies protein binding to a library of peptides directly synthesized on beads containing unique spectral codes.
