Atorvastatin prevents cadmium-induced renal toxicity in a rat model.

In many industrial processes, worker exposure to cadmium causes kidney damage; thus, protection against cadmium toxicity is important in workplace health. Cadmium toxicity involves oxidative stress by increasing the levels of reactive oxygen species. Statins have shown antioxidant effects that might prevent this increase in oxidative stress.

Regulatory effect of vitamin D on pro-inflammatory cytokines and anti-oxidative enzymes dysregulations due to chronic mild stress in the rat hippocampus and prefrontal cortical area.

Background: Chronic stress increases the production of pro-inflammatory cytokines and oxidative stress in the brain, which underlay cognitive and psychological problems. In addition to the anti-depressants, vitamin D is known to act as an anti-inflammatory and anti-oxidative agent. This study investigates the specific effects of vitamin D in protecting hippocampus and pre-frontal cortex (PFC) against chronic mild stress (CMS)-induced activation of pro-inflammatory cytokines IL-6 and TNF-α and decreasing the activation of anti-oxidative enzymes super oxide dismutase (SOD) and glutathione peroxidase (GPx).

Impact of different intensities of forced exercise on deficits of spatial and aversive memory, anxiety-like behavior, and hippocampal BDNF during morphine abstinence period in male rats.

Forced exercise can alleviate cognitive-behavioral deficits in an experimental model of addiction. However, the effects of different intensities of forced exercise in improving behavioral, cognitive and biochemical deficits during morphine abstinence period are not well investigated. Thus, the current work examined the effects of different loads of forced exercise on cognition functions, anxiety behavior and BDNF changes in the hippocampus, and prefrontal cortex (PFC), and also serum levels of BDNF and corticosterone during the abstinent period in male rats.

Hippocampal Up-Regulation of Apolipoprotein D in a Rat Model of Maternal Hypo- and Hyperthyroidism: Implication of Oxidative Stress.

Thyroid disorders impair various functions of the hippocampus where thyroid hormone receptors are localized in the brain. Hyper and hypothyroidism are associated with large changes in brain oxidative stress. Apolipoprotein D (APOD) is a conserved glycoprotein that increased in response to oxidative stress in the brain and has been suggested function as an antioxidant in the brain.

Probiotic supplementation attenuates hippocampus injury and spatial learning and memory impairments in a cerebral hypoperfusion mouse model.

Probiotics are referred to species of living microscopic organisms may help conserve the normal balance of the digestive system and/or manage diseases. A number of autoimmune, psychiatric, cardiovascular and cerebrovascular disorders may be associated with the imbalance of gut microbiota. This study examines the effect of 21 days consumption of multistrain probiotics on hippocampus injury, spatial and learning memory and some potential molecular mechanisms in a mouse model with cerebral hypoperfusion.

The present study investigated the combined protective effects of Spirulina platensis (SP), a supplement made from blue-green algae with neuroprotective properties, voluntary exercise (EX) and environmental enrichment (EE) against cognitive deficits, alternations in hippocampal BDNF levels, and abnormal neuronal remodeling in adult female rats (PND 60) induced by exposure to chronic restraint stress during adolescent period (PND 30-40). Rats were exposed to restraint stress (2 h/day for 10 days, PND 30-40).

Fluctuations of epigenetic regulations in human gastric Adenocarcinoma: How does it affect?

Gastric cancer (GC) or human gastric adenocarcinoma is one of the most commonplace type of serious cancers and also the most common cause of cancer-related mortality in the world. Relatively, many studies have acknowledged that GC is a multi-factorial pathological situation that environmental factors, particularly dietary ones and H.pylori infection are considered to have a strong key role in the etiology of GC.

CRP and LOX-1: a Mechanism for Increasing the Tumorigenic Potential of Colorectal Cancer Carcinoma Cell Line.

Chronic inflammation and dyslipidemia are associated with an increase in the incidence of colorectal cancer (CRC). Serum C- reactive protein (CRP) and oxidized low-density lipoprotein (oxLDL), as Lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1) ligands, increase during inflammation and dyslipidemia, respectively. To evaluate the effects of CRP on the expression of important genes involved in the development of CRC, the CRC cell line, LS174T, was treated with the commercial CRP.

This study examined the effects of treadmill exercise on the methadone withdrawal -induced locomotor sensitization, the ventral tegmental area (VTA) and ventral pallidum (VP) BDNF levels in morphine withdrawn rats receiving methadone maintenance treatment (MMT). The rats were chronically treated with bi-daily doses (10 mg/kg, at 12 h intervals) of morphine for 14 days. The exercising rats receiving MMT were forced to run on a motorized treadmill for 30 days during morphine withdrawal.

Neuroprotective nature of adipokine resistin in the early stages of focal cerebral ischemia in a stroke mouse model.

New evidence suggests that resistin may have a therapeutic potential effect in management of neurodegenerative disease; but its role in the pathophysiology of stroke-induced injuries is not understood.

Evaluation of the Effect of Promoter Type on the Immunogenicity of the Live Recombinant Vaccines Expressing Heat-labile Enterotoxins (LTB).

Enterotoxigenic (ETEC)-induced diarrhoea is the second most common cause of death in children in the developing countries. Heat labile toxin (LT) is responsible for ETEC-induced diarrhoea. In the present study, a novel live ETEC vaccine based on subunit B of LT (LTB) expression in attenuated PhoP strain was developed.

Forced exercise attenuates neuropathic pain in chronic constriction injury of male rat: an investigation of oxidative stress and inflammation.

Background And Objective: Initial peripheral/central nerve injuries, such as chronic constriction injury (CCI)/spinal cord injury, are often compounded by secondary mechanisms, including inflammation and oxidative stress, which may lead to chronic neuropathic pain characterized by hyperalgesia or allodynia. On the other hand, exercise as a behavioral and non-pharmacological treatment has been shown to alleviate chronic neuropathic pain. Therefore, this study was conducted to examine whether or not exercise reduces neuropathic pain through modifying oxidative stress and inflammation in chronic constriction injury of the sciatic nerve.
