The Role and Mechanism of Perilla Alcohol in Counteracting Doxorubicin-Induced Nephrotic Syndrome.

Background: Doxorubicin (DOX) is a widely used anticancer drug; However, its nephrotoxicity limits its therapeutic efficacy. This study investigates the protective effects of Perilla Alcohol (PA) against DOX-induced nephrotic syndrome (NS), focusing on its antioxidant and anti-inflammatory properties through the nuclear factor erythroid 2-related factor 2 (Nrf2) and nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) pathways.

Methods: A DOX-induced nephrotic syndrome (NS) rat model and a DOX-treated Mouse Podocyte Cell line 5 (MPC5) cell model were used to evaluate the renal protective effects of PA.

Research on investment optimization and coordination of fresh supply chain considering misreporting behavior under blockchain technology.

In the traditional fresh supply chain, farmers commonly conceal the true quality information of their products in order to achieve better sales. This article focuses on the use of blockchain technology to address the issue of false freshness reporting in a two-level fresh supply chain consisting of a rural cooperative and a supermarket. Taking into account the dual losses of quality and quantity in the process of agricultural products transportation, the impacts of the product freshness and the blockchain investment level on random market demand are quantified in this paper.

However, the role of alcohol in promoting neurotoxicity and neurodegeneration remains unclear.

[Molecular chaperones facilitate soluble expression of recombinant non-toxic mutant CRM197 of diphtheria toxin in Escherichia coli].

Diphtheria toxin is an ADP-ribosyltransferase toxic to human cells. Mutation of the active site in its catalytic domain eliminates the toxicity, but retains its immunogenicity. A non-toxic mutant of diphtheria toxin known as CRM197 protein has become an ideal carrier protein for conjugate vaccines.

Inhibition of cystathionine β-synthase promotes apoptosis and reduces cell proliferation in chronic myeloid leukemia.

Increased endogenous hydrogen sulfide (HS) level by cystathionine β-synthase (CBS) has been shown to closely relate tumorigenesis.

Resveratrol relieves ischemia-induced oxidative stress in the hippocampus by activating SIRT1.

Resveratrol, a naturally occurring phytoalexin, acts as an activator of sirtuin 1 (SIRT1) and has been shown to have a neuroprotective role in various models. Healthy adult male Sprague-Dawley rats were subjected to cerebral ischemia in order to study the protective effect of resveratrol on the brain following ischemia, and to investigate the effects of SIRT1 activation on the hippocampus. Untreated and resveratrol-treated rats were anesthetized prior to undergoing surgery to induce middle cerebral artery occlusion followed by reperfusion.

Long-term potentiation decay and memory loss are mediated by AMPAR endocytosis.

Long-term potentiation (LTP) of synaptic strength between hippocampal neurons is associated with learning and memory, and LTP dysfunction is thought to underlie memory loss. LTP can be temporally and mechanistically classified into decaying (early-phase) LTP and nondecaying (late-phase) LTP. While the nondecaying nature of LTP is thought to depend on protein synthesis and contribute to memory maintenance, little is known about the mechanisms and roles of decaying LTP.

[Adaptive changes of Zebrafish (Danio rerio) to anaerobic exercise training].

To explore adaptive changes of the Zebrafish (Danio rerio) to anaerobic exercise training as well as to collect basic data of molecular mechanisms of adaption to anaerobic exercise training among this fish, we investigated the influences of 4 weeks of anaerobic exercise training on the behavior, morphology, growth, muscle biochemical components and metabolic enzyme activities of the Zebrafish. Our results indicated that individual's daily activity level declined after 4 weeks training and they preferred to swim together more frequently. Both body length and weight gain decreased, allowing the fish to adapt to the increased locomotion.
