Alzheimer's disease (AD) is the most prevalent neurodegenerative disorder among the elderly. Because the existing treatments for Alzheimer's disease only offer limited symptomatic alleviation, more efficient therapeutic agents are urgently needed. Date seed is a hepatoprotective and neuroprotective agent. Date seed extract (DSE) has bioactive components like phenolics, flavonoids, and vitamins. In view of the ameliorative effects of DSE against an oxidative injury, the current study was designed to reveal whether DSE has a neuroprotective resource in the rat model of Alzheimer's disease...

BACKGROUND: High concentrations of methylglyoxal (MGO) cause cytotoxiticy via formation of advanced glycation endproducts (AGEs) and inflammation. MGO is detoxificated enzymatically by glyoxalase-I (Glo-I). The aim of this study was to analyze the role of Glo-I during the development of cirrhosis. METHODS: In primary hepatocytes, hepatic stellate cells (pHSC) and sinusoidal endothelial cells (pLSEC) from rats with early (CCl4 8wk) and advanced cirrhosis (CCl4 12wk) expression and activity of Glo-I were determined and compared to control...

Oligodendrocyte progenitor cells (OPCs) death is a key contributor to cerebral white matter injury (WMI) in the developing brain. A previous study by our group indicated that receptor-interacting proteins (RIPs) are crucial in mediating necroptosis in developing neurons. However, whether this mechanism is involved in OPCs death is unclear. We aimed to explore the mechanisms of RIP-mediated oligodendrocytes (OLs) death in the developing brain. Oligodendrocytes necroptosis was induced by oxygen-glucose deprivation plus caspase inhibitor zVAD treatment (OGD/zVAD) in vitro...

Nox-dependent signaling plays critical roles in the development of heart failure, cardiac hypertrophy, and myocardial infarction. NADPH oxidase 4 (Nox4) as a major source of oxidative stress in the heart offers a new therapeutic target in cardiovascular disease. In the present work, a novel flavonoid was isolated from Zanthoxylum bungeanum. Its structure was elucidated as Quercetin-3-O-(6''-O-α-l-rhamnopyransoyl)-β-d-glucopyranoside-7-O-β-d-glucopyranoside (ZYZ-772) for the first time. ZYZ-772 exhibited significant cardio-protective property against CoCl₂ induced H9c2 cardiomyocyte cells injury...

Cytochrome P450-mediated metabolism of arachidonic acid (AA) is an important pathway for the formation of eicosanoids. The ω-hydroxylation of AA generates significant levels of 20-hydroxyeicosatetraenoic acid (20-HETE) in various tissues. In the current review, we discussed the role of 20-HETE in the kidney, liver, lung, and brain during physiological and pathophysiological states. Moreover, we discussed the role of 20-HETE in tumor formation, metabolic syndrome and diabetes. In the kidney, 20-HETE is involved in modulation of preglomerular vascular tone and tubular ion transport...

OBJECTIVES: Carisbamate (CRS) is a novel monocarbamate compound that possesses antiseizure and neuroprotective properties. However, the mechanisms underlying these actions remain unclear. Here, we tested both direct and indirect effects of CRS on several cellular systems that regulate intracellular calcium concentration [Ca(2+) ]i . METHODS: We used a combination of cellular electrophysiologic techniques, as well as cell viability, Store Overload-Induced Calcium Release (SOICR), and mitochondrial functional assays to determine whether CRS might affect [Ca(2+) ]i levels through actions on the endoplasmic reticulum (ER), mitochondria, and/or T-type voltage-gated Ca(2+) channels...

Endothelin-1 (ET-1) promotes renal damage during cardiovascular disease; yet, the molecular mechanisms involved remain unknown. Endoplasmic reticulum (ER) stress, triggered by unfolded protein accumulation in the ER, contributes to apoptosis and organ injury. These studies aimed to determine whether the ET-1 system promotes renal ER stress development in response to tunicamycin. ETB deficient (ETB def) or transgenic control (TG-con) rats were used in the presence or absence of ETA receptor antagonism. Tunicamycin treatment similarly increased cortical ER stress markers in both rat genotypes; however, only ETB def rats showed a 14-24 fold increase from baseline for medullary GRP78, sXBP-1, and CHOP...

Idiopathic pulmonary fibrosis (IPF) is a fatal disease characterized by interstitial remodelling, leading to compromised lung function. Cellular senescence markers are detectable within IPF lung tissue and senescent cell deletion rejuvenates pulmonary health in aged mice. Whether and how senescent cells regulate IPF or if their removal may be an efficacious intervention strategy is unknown. Here we demonstrate elevated abundance of senescence biomarkers in IPF lung, with p16 expression increasing with disease severity...

The Vila Franca de Xira Hospital is located in the region with the highest number of festivals and bullfighting activities of Portugal. As a natural consequence, the hospital ends up with a particular experience in the treatment of victims of bullfighting accidents. These are usually common people harvested in street celebrations during the traditional festivals of the region, but also workers such as cattle herders, foremen, ranchers and others who handle the wild cattle and in particular those who deal with the bulls, such as forcados, banderilleros, matadors and cavaleiros...

Diabetic nephropathy (DN) is one of the most common microvascular diabetic complications. This study was designed to evaluate the possible protective effect and underlying mechanisms of HO-1 induction in streptozotocin (STZ)-induced early DN in rats. The diabetic rats were divided into three groups: STZ-diabetic, cobalt protoporphyrin (CoPP)-treated diabetic, and zinc protoporphyrin IX (ZnPP)-treated diabetic groups. Compared to the STZ-diabetic group, CoPP-induced HO-1 upregulation improved the diabetic state and renal functional parameters, suppressed the renal proinflammatory marker, NF-κB, abrogated the elevated renal hydroxyprolin, and decreased the enhanced renal nicotinamide adenine dinucleotide phosphate oxidase activity with parallel reduction of urinary oxidative stress markers...

Cardiovascular disease is a significant cause of morbidity and mortality around the world. The damaged cardiac tissue is unable to repair itself following injury warranting the development of alternate therapies. Cell therapy has emerged recently as a viable treatment option resulting in significant improvement in cardiac function. Nevertheless, donated stem cells are hard to find in the heart after transplantation leading to the hypothesis that release of extracellular factors by stem cells is primarily responsible for the beneficial effect of cell therapy...

The limited capacity for the central nervous system (CNS) to repair itself was first described over 100 years ago by Spanish neuroscientist Ramon Y. Cajal. However, the exact mechanisms underlying this failure in neuronal regeneration remain unclear and, as such, no effective therapeutics yet exist. Numerous studies have attempted to elucidate the biochemical and molecular mechanisms that inhibit neuronal repair with increasing evidence suggesting that several inhibitory factors and repulsive guidance cues active during development actually persist into adulthood and may be contributing to the inhibition of repair...
