  2024-10-28

  

  Cerebral ischemia occurs following the occlusion of a cerebral artery by a thrombus and causes cell swelling due to cytotoxic edema and BBB disruption with vasogenic edema (Loreto and Reggio, 2010, Nakaji et al., 2006, Shibata et al., 2004). Vasogenic edema is directly linked to alteration of the BB

  A large number of studies have shown that oxidative stress is involved in the pathophysiological process of ventricular remodeling and is associated with left ventricular dysfunction (Hori and Nishida, 2009, Lord et al., 2010). The generation of reactive oxygen species (ROS) that exceeds anti-oxidat

  Despite their different effects on cell survival, the functions of autophagy and apoptosis are not completely independent. Additionally, Cho et al. (2009) suggested that the mediation of caspase-3 links the apoptotic and autophagic signaling pathways. Consequently, to illuminate the correlation, exc

  2024-10-28

  

  There is a delicate balance between ROS generation and scavenging by the protective antioxidant defenses in the cell. Antioxidant systems present in the ID-8 include enzymes like superoxide dismutase (SOD), catalases, glutathione peroxidases (GPxs) and peroxiredoxins (PRxs) (Fig. 3) [38]. SODs are r

  Introduction Active oxygen radicals in the human body have a strong effect of inducing lipid peroxidation, which in turn induces oxidative imbalance and causes various diseases. Natural polysaccharides are substances with certain antioxidant activity. They are used as antioxidants and have advant

  2024-10-26

  

  Previous studies have demonstrated that synaptic AMPARs can differ greatly in their mobility; some rapidly and constitutively Agar in and out of the synaptic membrane, while others remain somewhat stable in the synaptic membrane (Luscher et al., 1999, Luthi et al., 1999). We find that mGluR- and NM

  2024-10-26

  

  Norepinephrine and epinephrine are catecholamines (CA) released from synaptic nerves and the adrenal gland that mediate systemic responses to nutritional stressors (Cannon and De la Paz, 1911). CA mobilize plasma glucose by suppressing insulin secretion from the pancreatic β-cell (Katada and Ui, 198

  Encouraged by this observation, a systematic SAR study on the A ring -alkoxy was conducted as summarized in . The A ring methoxy-containing KRCA-0008 was proven an optimal substituent in terms of potency after all and its bigger size derivatives were detrimental in both biochemical and H3122 cellula

  We have previously reported alterations of the thymus in AChR-MG patients, especially in their germinal center Tanshinone I (defined as CD19+CD38+ cells by flow cytometric analysis). First, we found that, in MG thymi, this subset failed to show the normal down-regulation of Bcl-2, suggesting that au

  Most studies on d-penicillamine-induced MG were performed before the discovery that some MG patients have anti-MuSK antibodies. After the identification of the present case, we retrospectively tested the stored frozen sera of ten earlier identified d-penicillamine MG patients with anti-AChR Trehalos

  The Kelch-like ECH-associated protein 1 (Keap1)-Nrf2 signaling pathway functions as one of the key regulator of the cellular defense system against oxidative stress [26]. Nrf2 is a redox-sensitive transcription factor, that is sequestered in the cytoplam by binding to Keap1; however, under oxidative

  However, there are studies revealing the “dark side” of autophagy at later stages in cancers, when oncogenes (mainly K-ras and B-raf) are activated and/or tumour suppressors such as PTEN and p53 are inactivated. These studies are based on the use of GEMM and deletions of essential autophagy genes (A
