Glyphosate [N-(phosphonomethyl) glycine], a systemic herbicide, is used globally (825 million kg/year) in 750+ formulations. The International Agency for Research on Cancer classified glyphosate is a probable human carcinogen (Group 2A), but epidemiological studies have been lacking for its association with liver cancer and chronic liver disease. We analyzed urine specimens from 591 patients with newly diagnosed liver cancer, chronic liver disease (CLD), and healthy individuals from five different medical centers between 2011 to 2016 in Thailand.

The synthesis and characterization of a new ligand, 1-(bis(pyridin-2-ylmethyl) amino)-2-methylpropane-2-thiolate (BPAS) and its nonheme iron complex, Fe(BPAS)Br (1), is reported. Reaction of 1 with O at -20 °C generates a high-spin iron(III)-hydroxide complex, [Fe(OH)(BPAS)(Br)] (2), that was characterized by UV-vis, Fe Mössbauer, and electron paramagnetic resonance (EPR) spectroscopies, and electrospray ionization mass spectrometry (ESI-MS). Density functional theory (DFT) calculations were employed to support the spectroscopic assignments.

The biological sex estimation of human individuals can be achieved by extracting fragments of the amelogenin protein from small areas of tooth enamel. The amelogenin gene can be found on both sex chromosomes (X and Y) with chromosome-specific differences in its sequence, and consequently the sequences of the expressed protein in teeth. Virtually all current analytical techniques used to identify the occurrence of the male Y chromosome-specific proteoform employ proteoform-specific peptide analysis by LC-ESI MS/MS, which typically results in longer analytical times due to the LC separation step, despite recent efforts of shortening the LC step.

Recently in the USA, kratom consumers increasingly report use of the plant for self-treatment of mood ailments, the lack of energy, chronic pain, and opioid withdrawal and dependence. Several alkaloids are present in kratom leaves, but limited data are available on their pharmacokinetics/pharmacodynamics, except for mitragynine. To support clinical studies, a high-performance liquid chromatography-tandem mass spectrometry assay for the simultaneous quantification of 11 kratom alkaloids in human plasma was developed and validated.

Idiopathic pulmonary fibrosis (IPF) is a prevalent chronic lung condition of unknown etiology characterized by fibrosis and inflammation. Lung scarring progresses owing to cytokines and immune cells that promote inflammation and fibrosis in idiopathic pulmonary fibrosis (IPF). The anti-inflammatory and anti-fibrotic properties of the ethyl acetate extract of Clerodendrum phlomidis (CPEA), derived from the Indian plant "agnimantha," are recognized in traditional Ayurvedic medicine.

Background And Objectives: Accurate triage at the time of emergency department (ED) presentation is critical for timely acuity assessment and anticipating resource requirements. Commonly, triage is conducted using the Emergency Severity Index (ESI); however, the accuracy of this approach for children in general EDs is uncertain. The purpose of this study was to quantify pediatric triage accuracy in a national sample of ED visits and evaluate whether presentation to a pediatric vs general ED is associated with mistriage.

In this study, a comparison of biofilm formation, extracellular polymeric substances (EPS) production, protein and polysaccharides estimation, and protein profiling through SDS-PAGE, FTIR, GC-MS, ESI-MS, SEM, and AFM analysis were done for EPS from epilithic bacteria BC1 obtained from monumental rock under normal room temperature and heat stressed condition. Heat stress (60 ± 2 °C) that simulates hot monumental rock surfaces during the summer season caused bacteria BC1 to produce more EPS (8.56 g/L), biofilm, protein and polysaccharides, extra SDS-PAGE protein bands of different molecular weight than their control counterpart.

Ag/Cu bimetallic clusters have been widely reported, but synthesis of such clusters simple self-assembly of heterometallic ions in air remains challenging due to the susceptibility of Cu ions to oxidation. In this study, protected by the phenylacetylene auxiliary ligand, we utilized [Cu(CHCN)]PF in conjunction with the (PrSAg) polymer to form Ag(I)-Cu(I) oligomer precursors, serving as the starting point for constructing a new [AgCu(PrS)(DPPM)](PF) cluster (DPPM = bis(diphenylphosphino)methane, Ag11-xCux, = 5-9). When the (PrSAg) precursor was replaced by (BuSAg), another cluster [AgCuS(BuS)(CHCN)](CHOH)(HO)(PF) (Ag21Cu4) was obtained.
