Abstract:
SummaryGlobally, smokeless tobacco (ST) includes a wide array of chemically diverse products generally used in the oral cavity. Although ST has been widely investigated, this study was undertaken to determine the levels of sugars (mono- and di-saccharides), alditols, and humectants present in major ST categories/subcategories by using high performance liquid chromatography coupled with a triple quadrupole mass spectrometer (HPLC-MS/MS). The products studied included chewing tobacco (loose leaf, plug, twist), US moist snuff, Swedish snus, creamy snuff, dry snuff, dissolvable tobacco products, a

Gelatin is a high-risk ingredient in terms of its halal status. Liquid chromatography combined with mass spectrometry (LC-MS/MS) was used to identify the source of gelatin based on marker peptides and proved to deliver higher reliability than other methods. However, the digestion method is essential before LC-MS/MS analysis. This research evaluated different digestion methods against selected porcine gelatin marker peptides and assessed LC-MS/MS sensitivity through adulteration experiments in various mixed matrices.

A liquid-liquid extraction and liquid chromatography-electrospray ionization tandem mass spectrometry (LC-MS/MS) method to determine iodothyronines and thyronamines (TAM) from cell culture media was developed. Thyroid hormones (TH) are metabolized by sequential deiodination to eventually yield thyronine (T₀), but can also be decarboxylated, resulting in TAM. The method presented here for extraction of DMEM/F12 cell culture media is a fundamental procedure for a precise determination of 9 TH and 6 TAM from a single LC run.

There has been growing interest in the use of polymer pyroelectrics for IR detection. Vinylidenefluoride-trifluoroethylene (VDF/TrFE) copolymer is flexible, crystallizes naturally into a polar β form, and can be rendered pyroelectric without being stretched. We have developed a series of composite materials based on poly(VDF/TrFE):(70/30) containing different concentrations of the ceramics: BaTiO3, PbZrO3, LiTaO3, and PbTiO3. Infrared detectors were fabricated by direct deposition of the composite thin films (2–75µm thick) onto substrates preconnected to the readout electronics. Dielectric pro

Abstract:
This work was in response to the Defense Logistic Agency’s (DLA) Subsistence Network Broad Agency Announcement, BAA-0003-16 addressing 2019 NDAA Section 329 that states packaging materials used for Meals Ready-to-Eat (MRE) that contact food products must be free of per- and polyfluoroalkyl substances (PFAS). This was addressed by determining the presence or absence of PFAS on MREs by extraction followed by gas chromatography mass spectrometry (GC-MS) and liquid chromatography tandem mass spectrometry (LC-MS/MS). Any samples positive for PFAS were quantitated using LC triple quadrupole (QqQ) MS

Abstract:
Background to the topic: For food safety and security reasons, hundreds of pesticides, veterinary drugs, and environmental pollutants should be monitored in the food supply, but current methods are too time-consuming, laborious, and expensive. As a result, only a tiny fraction of the food is tested for a limited number of contaminants. Original proposal objectives: Our main original goal was to develop fast, practical, and effective new approaches for the analysis of hazardous chemicals in the food supply. We proposed to extend the QuEChERS approach to more pesticides, veterinary drugs and pol

Abstract:
Japanese encephalitis virus (JEV), a mosquito-borne flavivirus, is a major cause of viral encephalitis in Asia. Even though the principle target cells for JEV in the central nervous system are neurons, the microglia is activated in response to JEV infection. This research aimed to investigate the relationship between JEV and microglial cells. The percentage of JEV infectivity in mouse microglial (BV-2) cell line at 8, 15 and 24 hr post infection was determined by flow cytometry. It was found that the percentage of infected cells were approximately 53.5, 71.3 and 83.6 respectively. The JEV bind

Abstract:
In this study, we investigated neuroinfectious capacity of H5N1 (A/Thailand/NK165/2005) isolated from plasma of infected individual during the third wave of Thailand outbreaks using human neuroblastoma SH-SY5Y cells. This was due to lack of information regarding neuroinfectivity of this variant. Results demonstrated that H5N1/NK165 induced servere CPEs in these neuronal cells. H5N1-specific hemagglutinin was found in the cytoplasm of the infected cells as early as 12 h post-infection. By 24 h post-infection, all cells in the cultures were infected. These findings coincided with time course of

Abstract:
Blood pressure regulation is partially dependent on the renin-angiotensin system; renin acts on angiotensinogen to release angiotensin-I, which is further converted into the angiotensin II by the angiotensin I-converting enzyme (ACE). ACE plays a key physiological role in the regulation of blood pressure by virtue of two different reactions that it catalyzes: conversion of the inactive angiotensin I to the powerful vasoconstrictor angiotensin II, and inactivation of the vasodilator bradykinin.

Abstract:
Innate immune responses in animals and plants involve receptors that recognize microbe-associated molecules. In plants, one set of this defense system is characterized by large families of TIR–nucleotide binding site–leucine-rich repeat (TIR-NBS-LRR) resistance genes. The direct interaction between plant proteins harboring the TIR domain with proteins that transmit and facilitate a signaling pathway has yet to be shown. The Arabidopsis genome encodes TIR-domain containing genes that lack NBS and LRR whose functions are unknown. Here we investigated the functional role of such protein, TLW1 (TI
