Development partners and donors have encouraged and incentivized governments in developing countries to explore ways of working with third-party service suppliers to reduce costs and increase service delivery capacity. The distribution of vaccines and medicines has for a long time shown demand for outsourcing but public health systems have struggled to develop the expertise and capital assets necessary to manage such ventures. Existing transport and logistics capacity within public health systems, in particular, is well documented as being insufficient to support existing, let alone future immunization needs.

a Drug Safety Assessment, Novel Drug Discovery & Development , Lupin Limited (Research Park) , Taluka-Mulshi , Pune , India.

Non-genotoxic carcinogens may play a significant role in development of cancer. Currently short-term assays for mutagenicity classify genotoxic carcinogens and lack the abilities to detect epigenetic carcinogens. The need to develop an endpoint always remains to recognize potentially carcinogenic agents employing rapid and practical bioassays.

Solid-phase reductive amination for glycomic analysis.

Anal Chim Acta

April 2017

State Key Laboratory of Medicinal Chemical Biology, College of Pharmacy and Tianjin Key Laboratory of Molecular Drug Research, Nankai University, Tianjin 300353, China; Department of Chemistry, Georgia State University, Atlanta, GA 30303, United States. Electronic address:

Reductive amination is an indispensable method for glycomic analysis, as it tremendously facilitates glycan characterization and quantification by coupling functional tags at the reducing ends of glycans. However, traditional in-solution derivatization based approach for the preparation of reductively aminated glycans is quite tedious and time-consuming. Here, a simpler and more efficient strategy termed solid-phase reductive amination was investigated.

Assistant Professor of Biochemistry, Department of Chemistry, Georgia Southern University, Statesboro, GA 30458 USA.

Background: A recent diabetes report revealed an increased incidence in diabetes including type 1-diabetes (T1D). The increase in the numbers of T1D incidences are thought to be related to environmental reasons such as the exposure to environmental chemicals including arylamine 2-aminoanthracene (2AA). T1D is an autoimmune disease of the pancreatic islet in which insulin-producing beta cells are destroyed by auto-reactive T-cells and monocytic cells.

Background: The rapidly expanding arsenal of chemotherapeutic agents approved in the past 5 years represents significant progress in the field. However, this poses a challenge for oncologists to choose which drug or combination of drugs is best for any individual. Because only a fraction of patients respond to any drug, efforts have been made to devise strategies to personalize care.

Capillary electrophoresis (CE) offers excellent efficiency and orthogonality to liquid chromatographic (LC) separations for oligosaccharide structural analysis. Combination of CE with high resolution mass spectrometry (MS) for glycan analysis remains a challenging task due to the MS incompatibility of background electrolyte buffers and additives commonly used in offline CE separations. Here, a novel method is presented for the analysis of 2-aminobenzoic acid (2-AA) labelled glycans by capillary electrophoresis coupled to mass spectrometry (CE-MS).

Article Synopsis
  • - The study investigates how exposure to the environmental contaminant 2-aminoanthracene (2AA) during pregnancy might increase the risk of type 2 diabetes in offspring by affecting adipose tissue function.
  • - Pregnant rats were given diets with varying levels of 2AA, and their offspring were analyzed for diabetes-related gene expression, serum glucose levels, and other health markers.
  • - Findings show that exposure to 2AA resulted in gene changes related to diabetes, higher blood sugar levels, and larger fat cells in treated offspring, suggesting a combined effect with a high-fat diet increases diabetes risk.

Human enterovirus D68 (EV-D68) was first reported in the United States in 1962; thereafter, a few cases were reported from 1970 to 2005, but 2 outbreaks occurred in the Philippines (2008) and the United States (2014). However, little is known regarding the molecular evolution of this globally reemerging virus due to a lack of whole-genome sequences and analyses. Here, all publically available sequences including 147 full and 1248 partial genomes from GenBank were collected and compared at the clade and subclade level; 11 whole genomes isolated in Taiwan (TW) in 2014 were also added to the database.

Individual variations in cytochrome P450-mediated metabolism are believed to contribute to individual susceptibility to chemical carcinogenesis. CYP1A2 is one of the major forms of cytochrome P450 involved in drug metabolism and bioactivation of carcinogens. We have applied a recently developed high-throughput Salmonella typhimurium TA1535 system for detection of DNA damaging agents to the study of CYP1A2 polymorphisms.

We previously showed that L-lysine (Lys) and a metabolite of Lys, L-saccharopine, suppressed autophagic proteolysis in C2C12 myotubes. However, the effects of other metabolites of Lys on protein turnover were unknown. We here investigated the effect of the Lys metabolites, L-2-aminoadipic acid (2-AA) and L-pipecolic acid (Pip), on protein turnover in C2C12 myotubes.

Mannose-6-phosphate (M-6-P) glycan plays an important role in lysosomal targeting of most therapeutic enzymes for treatment of lysosomal storage diseases. This article provides data for the analysis of M-6-P glycans by high-performance liquid chromatography (HPLC) and matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry. The identities of M-6-P glycan peaks in HPLC profile were confirmed by measuring the masses of the collected peak eluates.

Cancer cells predominantly metabolize glucose by glycolysis to produce energy in order to meet their metabolic requirement, a phenomenon known as Warburg effect. Although Warburg effect is considered a peculiarity critical for survival and proliferation of cancer cells, the regulatory mechanisms behind this phenomenon remain incompletely understood. We report here that eukaryotic elongation factor-2 kinase (eEF-2K), a negative regulator of protein synthesis, has a critical role in promoting glycolysis in cancer cells.
