[Determination of 17 perfluorinated/polyfluoroalkyl compounds in serum by high-throughput solid-phase extraction-ultra-high performance liquid chromatography-tandem mass spectrometry].

Perfluorinated/polyfluoroalkyl compounds (PFASs) are a group of synthetic chemicals. Since the 1940s, PFASs have been widely used in industrial and daily consumer fields. PFASs can enter the human body through various pathways, such as drinking water, food, and air.

Resveratrol affects proliferation, apoptosis and migration of fibroblast cells as well as inhibits COL1A1/2 and TGFB2/3 gene expression.

Primary fibroblasts isolated from pterygium and skin pathological scar were identified by immunofluorescence staining. It was found by CCK8 and TUNEL that high-dose resveratrol, a Chinese medicine monomer, could inhibit proliferation, promote apoptosis and restrain migration. Explored by whole-transcriptome sequencing and LC-MS/MS, 1531 up-regulated mRNAs, 1022 down-regulated mRNAs, 79 up-regulated proteins and 84 down-regulated proteins were identified in resveratrol-treated pterygium fibroblasts.

Evaluating the effects of silent genes on pairwise kinship testing.

Short tandem repeat (STR) loci are frequently utilized in kinship testing, and mutations of a single base occurring in the primer-binding region of the STR locus can result in the failure of allelic amplification and the emergence of silent genes. Silent genes are not observable and, therefore, are excluded from the genotypes assessed. Pedigree likelihood ratios (LRs) are often employed in kinship testing to determine the likelihood of different kinship scenarios.

Variations, effectiveness and its associated factors of a nationwide web-based hypertension management training project in China: insights from a government-led campaign for 1.2 million lay health workers.

Objectives: To evaluate the effectiveness of a large-scale, web-based, in-service hypertension management training project among lay health workers (LHWs) at primary care health (PHC) settings in China, and to examine the factors contributing to the variations of effectiveness.

Methods: We used data from a web-based national hypertension management training project implemented in 2018, it was designed to facilitate LHWs to learn, understand, and apply the relevant knowledge and skills in hypertension management through providing training courses by use of the web-based platform with unified standards. All LHWs were required to participate in the exams before and after training to acquire scores for the use of evaluating their performance of hypertension management knowledge.

Quantitative analysis of microglia morphological changes in the hypothalamus of chronically stressed rats.

Based on the successful establishment of a rat model of chronic restraint stress, we used multiple algorithms to quantify the morphological changes of rat hypothalamic microglia from various perspectives, providing a pathomorphological basis for the subsequent study of molecular mechanisms of hypothalamic stress injury, such as neuroinflammation. To verify the successful establishment of the chronic stress model, an enzyme-linked immunosorbent assay was performed to detect serum glucocorticoid levels. Microglia labeled with Iba1 in frozen sections of rat hypothalamus were scanned and photographed at multiple levels using confocal microscopy.

Herpes simplex virus 1 counteracts viperin via its virion host shutoff protein UL41.

The interferon (IFN)-inducible viperin protein restricts a broad range of viruses. However, whether viperin plays a role during herpes simplex virus 1 (HSV-1) infection is poorly understood. In the present study, it was shown for the first time that wild-type (WT) HSV-1 infection couldn't induce viperin production, and ectopically expressed viperin inhibited the replication of UL41-null HSV-1 but not WT viruses.

Molecular cloning and characterization of pseudorabies virus EP0 gene.

The pseudorabies virus (PRV) early protein EP0 is a homologue of the herpes simplex virus 1 (HSV-1) immediate-early protein ICP0, which is a multifunctional protein and important for HSV-1 infection. However, the exact function of EP0 is not clear. In this study, using polymerase chain reaction, a 1,104 base-pair sequence of the EP0 gene was amplified from the PRV Becker strain genome and identification of the EP0gene was confirmed by further cloning and sequencing.

Herpesviral infection and Toll-like receptor 2.

In the last decade, substantial progress has been made in understanding the molecular mechanisms involved in the initial host responses to viral infections. Herpesviral infections can provoke an inflammatory cytokine response, however, the innate pathogen-sensing mechanisms that transduce the signal for this response are poorly understood. In recent years, it has become increasingly evident that the Toll-like receptors (TLRs), which are germline-encoded pattern recognition receptors (PRRs), function as potent sensors for infection.
