Establishment of a Multiplex Detection Method for Common Bacteria in Blood Based on Human Mannan-Binding Lectin Protein-Conjugated Magnetic Bead Enrichment Combined with Recombinase-Aided PCR Technology.

Objective: Recombinase-aided polymerase chain reaction (RAP) is a sensitive, single-tube, two-stage nucleic acid amplification method. This study aimed to develop an assay that can be used for the early diagnosis of three types of bacteremia caused by (SA), (PA), and (AB) in the bloodstream based on recombinant human mannan-binding lectin protein (M1 protein)-conjugated magnetic bead (M1 bead) enrichment of pathogens combined with RAP.

Methods: Recombinant plasmids were used to evaluate the assay sensitivity.

A Multiplex Recombinase-Aided qPCR Assay for Highly Sensitive and Rapid Detection of khe, bla , and bla Genes in Klebsiella pneumoniae.

Objective: This study aimed to establish a highly sensitive and rapid single-tube, two-stage, multiplex recombinase-aided qPCR (mRAP) assay to specifically detect the khe, bla, and bla genes in Klebsiella pneumoniae.

Methods: mRAP was carried out in a qPCR instrument within 1 h. The analytical sensitivities of mRAP for khe, bla, and bla genes were tested using recombinant plasmids and dilutions of reference strains.

Differential Gut Microbiota Compositions Related With the Severity of Major Depressive Disorder.

Objective: Increasing evidence shows a close relationship between gut microbiota and major depressive disorder (MDD), but the specific mechanisms remain unknown. This study was conducted to explore differential gut microbiota compositions related to the severity of MDD.

Methods: Healthy controls (HC) (n = 131) and MDD patients (n = 130) were included.

Multi-omics data reveals the disturbance of glycerophospholipid metabolism caused by disordered gut microbiota in depressed mice.

Introduction: Although researchers have done intensive research on depression, its pathogenesis is still not fully explained. More and more evidence suggests that gut microbiota is closely related to the onset of depression; but its specific functional ways are not clearly identified.

Objectives: The purpose of our work was to find out how the gut microbiota was involved in the onset of depression, and to identify the potential ways to link the gut and brain in mice with depressive-like behaviors (DLB).

Sequential Whole Exome Sequencing Reveals Somatic Mutations Associated with Platinum Response in NSCLC.

Purpose: Resistance is one of the main limitations of successful platinum treatment in non-small-cell lung cancer (NSCLC) patients. In this study, we aimed to identify somatic mutations associated with platinum response.

Patients And Methods: A total of 57 patients who received platinum-based chemotherapy only and 13 patients who received neoadjuvant chemotherapy (NAC) were enrolled.

[Effect of resveratrol on body composition in adult catch-up growth rats and its mechanism].

Objective: To observe the effects of resveratrol on body composition in adult catch-up growth rats and to explore the possible mechanism.

Methods: Eight-week-old male SD rats were randomly divided into 6 groups: normal controls for 4 weeks (NC4) group, caloric restriction for 4 weeks (R4) group, calorie restriction meanwhile resveratrol treatment for 4 weeks (R4E) group, normal controls for 12 weeks (NC12) group, catch-up growth (CUG) group and catch-up growth meanwhile resveratrol treatment for 8 weeks (CUGE) group. At the end of the four-week and twelve-week experimental period, the body weight, muscle and fat content of trunk and whole body, the ratio of trunk to whole body fat were detected, and at the end of twelve-week experimental period, the expression of SIRT1 in skeletal muscle and epididymal adipose tissue, and the expression of PPARγ in epididymal adipose tissue were detected.

A Hereditable Mutation of MSH2 Gene Associated with Lynch Syndrome in a Five Generation Chinese Family.

Purpose: In order to clarify which variants of the MMR gene could provide current "healthy" members in affected families a more accurate risk assessment or predictive testing.

Patients And Methods: One family, which meets the criteria according to both Amsterdam I/II and Bethesda guidelines, is reported in this study. The proband and some relatives of the patient have been investigated for whole genome sequencing, microsatellite instability, immunohistochemical MMR protein staining and verified by Sanger sequencing.

Biomarkers identified for prostate cancer patients through genome-scale screening.

Prostate cancer is a threat to men and usually occurs in aged males. Though prostate specific antigen level and Gleason score are utilized for evaluation of the prostate cancer in clinic, the biomarkers for this malignancy have not been widely recognized. Furthermore, the outcome varies across individuals receiving comparable treatment regimens and the underlying mechanism is still unclear.

Severe disturbance of glucose metabolism in peripheral blood mononuclear cells of schizophrenia patients: a targeted metabolomic study.

Background: Schizophrenia is a widespread and debilitating mental disorder. However, the underlying molecular mechanism of schizophrenia remains largely unknown and no objective laboratory tests are available to diagnose this disorder. The aim of the present study was to characterize the alternations of glucose metabolites and identify potential diagnostic biomarkers for schizophrenia.

Combined Metabolomics and Proteomics Analysis of Major Depression in an Animal Model: Perturbed Energy Metabolism in the Chronic Mild Stressed Rat Cerebellum.

Major depressive disorder (MDD) is a highly prevalent, debilitating mental illness of importance for global health. However, its molecular pathophysiology remains poorly understood. Combined proteomics and metabolomics approaches should provide a comprehensive understanding of MDD's etiology.

Combined application of NMR- and GC-MS-based metabonomics yields a superior urinary biomarker panel for bipolar disorder.

Bipolar disorder (BD) is a debilitating mental disorder that cannot be diagnosed by objective laboratory-based modalities. Our previous studies have independently used nuclear magnetic resonance (NMR)-based and gas chromatography-mass spectrometry (GC-MS)-based metabonomic methods to characterize the urinary metabolic profiles of BD subjects and healthy controls (HC). However, the combined application of NMR spectroscopy and GC-MS may identify a more comprehensive metabolite panel than any single metabonomic platform alone.

Stereological investigation of age-related changes of the capillaries in white matter.

We, for the first time, investigated the age-related changes of the capillaries in white matter using immunohistochemistry and stereological techniques. Ten young female (7 months) and 10 aged female (27 months) rats were used. The total length, total volume, and total surface area of the capillaries in white matter of aged rats were all significantly lower than those of young rats.
