Lactobacillus casei Zhang prevents hippocampal atrophy and cognitive impairment in rats with type 2 diabetes by regulating blood glucose levels.

Purpose: Lactobacillus casei Zhang (LCZ) has health benefits, such as the ability to improve blood glucose levels in individuals with type 2 diabetes mellitus (T2DM). However, little is known about the effects of LCZ on brain structural plasticity and cognitive function in T2DM. The aims of this study were to determine whether LCZ can prevent and alleviate brain damage and memory impairment in T2DM, and to understand the mechanisms underlying the effects of LCZ in T2DM.

ZnO Nanoparticles-Induced MRI Alterations to the Rat Olfactory Epithelium and Olfactory Bulb after Intranasal Instillation.

Since zinc oxide (ZnO) nanoparticles (NPs) have been widely applied, the nano community and the general public have paid great attention to the toxicity of ZnO NPs. We detected 20-nm ZnO NPs biotoxicity following nasal exposure utilizing the non-invasive and real-time magnetic resonance imaging (MRI) technique. MR images were scanned in the rat olfactory epithelium (OE) and olfactory bulb (OB) on a 4.

Gut microbiota regulation of T lymphocyte subsets during systemic lupus erythematosus.

Background: Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by disturbance of pro-inflammatory and anti-inflammatory lymphocytes.

Fatty acid modification of antimicrobial peptide CGA-N9 and the combats against Candida albicans infection.

High-efficiency and low-toxic antimicrobial peptides (AMPs) are supposed to be the future candidates to solve the increasingly prominent problems of Candida albicans infection and drug resistance. Generally, introduction of hydrophobic moieties on AMPs resulted in analogues with remarkably increased activity against pathogens. CGA-N9, an antifungal peptide found in our lab, is a Candida-selective antimicrobial peptide capable of preferentially killing Candida spp.

Microbial induced calcium carbonate precipitation (MICP) refers to the natural biological process of calcium carbonate precipitation induced by microbial metabolism in its surrounding environment. Based on the principles of MICP, microbial cement has been developed and has received widespread attention in the field of biology, civil engineering, and environment owing to the merits of environmental friendliness and economic competence. Urease and carbonic anhydrase are the key enzymes closely related to microbial cement.

Comparative Transcriptome Analysis Reveals Mechanisms of Folate Accumulation in Maize Grains.

Previously, the complexity of folate accumulation in the early stages of maize kernel development has been reported, but the mechanisms of folate accumulation are unclear. Two maize inbred lines, DAN3130 and JI63, with different patterns of folate accumulation and different total folate contents in mature kernels were used to investigate the transcriptional regulation of folate metabolism during late stages of kernel formation by comparative transcriptome analysis. The folate accumulation during DAP 24 to mature kernels could be controlled by circumjacent pathways of folate biosynthesis, such as pyruvate metabolism, glutamate metabolism, and serine/glycine metabolism.

Post-PCI outcomes predicted by pre-intervention simulation of residual quantitative flow ratio using augmented reality.

Background: The simulated residual quantitative flow ratio (QFR) computed from pre-intervention three-dimensional (3-D) coronary angiograms, which could theoretically predict actual post-percutaneous coronary intervention (PCI) QFR value, can be used for enhanced PCI via augmented reality. The study sought to investigate the concordance between simulated residual QFR and actual post-PCI QFR, and the prognostic value of simulated residual QFR.

Methods: QFR assessment was retrospectively performed in treated vessels from the all-comers PANDA III trial.

Design of a Genetically Programmed Biomimetic Lipase Nanoreactor.

Alternative to the traditionally independent production of lipase, chemical synthesis of nano-carriers, and then preparing nanoimmobilized enzymes, we exploit a yeast genetically programmed virus biomimetic lipase nanoreactor in a sustainable manner. The nanoreactor biogenesis process integrated lipase production, protein component (coat-protein subunit and scaffold protein) production, self-assembly of protein components, and the encapsulation of lipase into protein nanocages using a simple process. It included overexpression of nanocage components, coat-protein subunits, and fused lipase-scaffold proteins and subsequent spontaneous self-assembly and encapsulation based on the specific interaction between the coat-protein subunit and the scaffold protein fused in the target lipase enzyme.

Cost-effectiveness analysis of domestic 13-valent pneumococcal conjugate vaccine for children under 5 years of age in mainland China.

: The first Chinese domestic 13-valent pneumococcal conjugate vaccine (WoAnxin®, PCV-13) is available for children aged 2 months to 5 years and is more economical than import vaccine with equal safety and immunogenicity. However, the cost-effectiveness of this new PCV-13 for children <5 years in mainland China is not clear. : In the present study, we developed a Markov model under societal perspective to evaluate the incremental cost-effectiveness ratios (ICERs) of five birth cohorts of 100,000 Chinese infants across four alternative vaccination programs:1) no vaccination; 2) vaccinate 4 doses of new PCV-13 for children aged 2 to 6 months; 3) vaccinate 3 doses of new PCV-13 for children aged 7 to 11 months; 4) vaccinate 2 doses of new PCV-13 for children aged 12 to 23 months; 5) vaccinate 1 dose of new PCV-13 for children aged 2 to 5 years.

ATF3 downmodulates its new targets IFI6 and IFI27 to suppress the growth and migration of tongue squamous cell carcinoma cells.

Activating transcription factor 3 (ATF3) is a key transcription factor involved in regulating cellular stress responses, with different expression levels and functions in different tissues. ATF3 has also been shown to play crucial roles in regulating tumor development and progression, however its potential role in oral squamous cell carcinomas has not been fully explored. In this study, we examined biopsies of tongue squamous cell carcinomas (TSCCs) and found that the nuclear expression level of ATF3 correlated negatively with the differentiation status of TSCCs, which was validated by analysis of the ATGC database.
