Depressive disorder is a mental health disorder caused by the dysfunction of nerve regeneration, neuroendocrine and neurobiochemistry, which frequently results in cognitive impairments and disorder. Evidence has shown that resveratrol offers benefits for the treatment of depressive disorder. In the present study, the therapeutic effects of resveratrol were investigated and the potential mechanisms mediated by resveratrol were analyzed in hippocampal neuron cells. The anti‑oxidative stress and anti‑inflammatory properties of resveratrol were also examined in vitro and in vivo...

Endometriosis is a dyshormonal immune-dependent genetically determined disease, which appears as an endometrioid tissue that grows outside the uterine. Endometriosis is one of the most urgent problems of medicine. To date, new concepts of the endometriosis etiology and pathogenesis have been developed, but, despite their abundance, there is no unified theory. Genetic and epigenetic factors result in changes in an expression of aromatase, steroidogenic factor 1, and estrogen receptors are suggested to be the main cause of endometriosis...

An ischemia/reperfusion injury of rat's sciatic nerve was experimentally developed. In this model, we measured the in vivo production of superoxide radical, as a marker of oxidative stress and the occludin expression as an indicator of blood-nerve barrier function and we examined potential protective innervations against these abnormalities. Right sciatic nerves of the animals underwent 3 h of ischemia followed by 7 days of reperfusion and were divided into three groups: ischemic, pretreated with vitamin C in conjunction with vitamin E and treated with tissue plasminogen activator...

In Viperidae snakes, it has been attributed to the main venom gland, a component of the venom gland apparatus, the function of synthesizing all venom toxins and storing them inside a basal-central lumen. However, the role of the accessory gland is still unknown. Here, we analyzed the proteome and the transcriptome of the accessory gland during venom production and secretion cycle. We showed that the accessory gland expresses and synthesizes toxins that are similar to those produced by the main venom gland such as C-type lectin/C-type lectin-like proteins, metalloproteinase, phospholipase A2, cysteine rich secretory protein, nerve growth factor, vascular endothelial growth factor, serine proteinase, and l-amino acid oxidase...

Nerve agents still represent a serious threat to civilian and military personnel as demonstrated by the violent conflict in the Middle East. For verification of poisoning, covalent adducts with endogenous proteins (e.g., human serum albumin, HSA) are valuable long-term biomarkers. Accordingly, we developed a microbore liquid chromatography-electrospray ionization mass spectrometry/high-resolution mass spectrometry (μLC-ESI MS/HR MS) method for simultaneous detection of HSA-adducts with the V-type nerve agents VX, Chinese VX (CVX), and Russian VX (RVX)...

BACKGROUND Neuromyelitis optica (NMO) is a rare demyelinating disease of the central nervous system; NMO predominantly affects the spinal cord and optic nerves. The diagnosis is based on history, clinical presentation, seropositive NMO-IgG antibody, and notably, exclusion of other diseases. Despite the absence of definitive therapeutic strategies for NMO, methylprednisolone pulse therapy and plasma exchange are used for acute phase treatment, while immunosuppressive agent(s) are recommended to prevent relapses and improve prognosis...

In this work, we develop fluorescent hierarchical nanofiber bundles 1, which involve the internanofiber hydrogen-bonding interactions, for rapid and sensitive detection of DCP vapor. First, the internanofiber hydrogen-bonding strength can be weakened by photoexcitation, which thereby increases the internanofiber spacing and decreases the fluorescence intensity. Then, when exposed to trace DCP vapor, the strong interactions between DCP and hydroxyl groups on the nanofibers can effectively retighten the nanofibers and enhance the fluorescence as the detection signal...

Elevated N-methyl-D-aspartate receptor (NMDAR) activity is linked to central sensitization and chronic pain. However, NMDAR antagonists display limited therapeutic potential due to their adverse side effects. Novel approaches targeting the NR2B-PSD95-nNOS complex to disrupt signaling pathways downstream of NMDARs show efficacy in preclinical pain models. Here, we evaluated the involvement of interactions between neuronal nitric oxide synthase (nNOS) and the nitric oxide synthase 1 adaptor protein (NOS1AP) in pronociceptive signaling and neuropathic pain...

Hydrogen sulfide (H2S) is a colorless, highly neurotoxic gas. It is not only an occupational and environmental hazard but also of concern to the Department of Homeland Security for potential nefarious use. Acute high-dose H2S exposure causes death, while survivors may develop neurological sequelae. Currently, there is no suitable antidote for treatment of acute H2S-induced neurotoxicity. Midazolam (MDZ), an anti-convulsant drug recommended for treatment of nerve agent intoxications, could also be of value in treating acute H2S intoxication...

BACKGROUND: Chemotherapy-induced peripheral neuropathy (CIPN) is a common and clinically relevant side effect of chemotherapy. Approximately 50% of all leukemia, lymphoma, colorectal- and breast cancer patients are affected. CIPN is induced by neurotoxic chemotherapeutic agents and can manifest with sensory and/or motor deficits. It is associated with significant disability and poor recovery. Common symptoms include pain, altered sensation, reduced or absent reflexes, muscle weakness, reduced balance control and insecure gait...

REVIEW
Milton Packer
A primary goal of the treatment of type 2 mellitus is the prevention of morbidity and mortality due to cardiovascular disease. However, antihyperglycemic drugs have the capacity to cause deleterious effects on the circulation, a risk that is not adequately reflected by the endpoints selected for emphasis in large-scale clinical trials that are designed to evaluate cardiovascular safety. The primary endpoint of the large-scale studies mandated by regulatory authorities focuses only on 3-4 events that depict only a limited view of the circulatory system...

The function of the CXCR4/CXCL12 axis accounts for many disease indications, including tissue/nerve regeneration, cancer metastasis and inflammation. Blocking CXCR4 signaling with its antagonists may lead to moving out CXCR4+ cell types from bone marrow to peripheral circulation. We have discovered a novel series of pyrimidine-based CXCR4 antagonists, a representative (i.e., 16) of which was tolerated at a higher dose and showed better HSC-mobilizing ability at the maximal response dose relative to the approved drug 1 (AMD3100), and thus considered a potential drug candidate for PBSCT indication...

Amino functionalized Zr-based metal-organic frameworks have shown unprecedented catalytic activity compared to non-functionalized analogues for hydrolysis of organophosphonate-based toxic chemicals. Importantly, the effect of the amino group on the catalytic activity is significantly higher in the case of UiO-66-NH2 where the amino groups reside in the vicinity of the node compared to UiO-67-m-NH2 they are directed away from the node. Here, we have revealed that the proximity of the amino group is crucial to observe fast catalytic activity towards hydrolysis of organophosphonate-based nerve agents...

The mechanisms by which the heavy metal thallium (Tl+) produces toxicity in the brain remain unclear. Herein, isolated synaptosomal/mitochondrial P2 crude fractions from adult rat brains were exposed to Tl+ (5-250 μM) for 30 min. Three toxic endpoints were evaluated: mitochondrial dysfunction, lipid peroxidation, and Na+/K+-ATPase activity inhibition. Concentration-response curves for two of these endpoints revealed the optimum concentration of Tl+ to induce damage in this preparation, 5 μM. Toxic markers were also estimated in preconditioned synaptosomes incubated in the presence of the N-methyl-D-aspartate receptor antagonist kynurenic acid (KYNA, 50 μM), the cannabinoid receptor agonist WIN 55,212-2 (1 μM), or the antioxidant S-allyl-L-cysteine (SAC, 100 μM)...

Background: Painful diabetic neuropathy (PDN) is a common complication in patients with diabetes. It is related to ischemic nerve damage and the increase in the levels of proinflammatory mediators, such as tumor necrosis factor α (TNF-α) and interleukin 1β (IL-1β). Neural mobilization may have the potential to alleviate PDN, but it has not yet been tested. Also, the physiological mechanism of neural mobilization is unclear. Objective: The objective of this study was to investigate treatment effect and physiological mechanism of neural mobilization...

Radiofrequency-based electrophysical agents (EPA) have been used in therapy practice over several decades (e.g., shortwave therapies). Currently, there is insufficient evidence supporting such devices operating below shortwave frequencies. This laboratory-based study investigated the skin physiological effects of 448 kHz capacitive resistive monopolar radiofrequency (CRMRF) and compared them to pulsed shortwave therapy (PSWT). In a randomised crossover study, seventeen healthy volunteers received four treatment conditions - High, Low and Placebo dose conditions receiving 15-min CRMRF treatment and a Control condition receiving no intervention...
