  Many reports have well documented that signaling pathways play a pivotal role in controlling longevity. The most studied of these pathways is the IGF-1 pathway [11,12]. A disruption of this pathway has been found to extend longevity in different groups of species starting from Caenorhabditis elegan

  2024-12-10

  

  Introduction Melatonin (N-acetyl-5-methoxytryptamine) is a neurohormone which is mainly secreted from the pineal gland. Melatonin is a highly conserved molecule present not only in vertebrates but also in nonvertebrates such as bacteria, protists, fungi, macroalgae, and plants (Cecon et al., 2017

  Introduction Initially postulated to represent the main source of ATP production in eukaryotic cells, mitochondria are recently recognized to perform manifold essential functions beyond energy production, impacting most areas of cell biology and medicine [1]. Mitochondrial metabolism is both the ba

  To introduce in a simple way the variability in the concentration of the proteins involved in the process, and to consider possible stochastic effects due to possible finite sizes of the populations involved in the problem, the dynamics of each cell is studied using the Gillespie’s algorithm (Gilles

  However, one should keep in mind that these results may not reflect exactly in vivo antioxidant activity. Many other issues such as absorption, metabolism and physicochemical properties of different antioxidants must also be considered (Prior et al., 2007, Wu et al., 2004). Some research groups are

  2024-12-10

  

  Angiogenesis is a process of formation of new vessels from arterial vascularization created by endothelial cells. It is essential for the continuous growth of the tumor because it supplies the tumor with nutrients and oxygen, and eliminates cellular waste, which can be toxic to cancer cells [8]. Inf

  Within the thrombus, there is heterogeneity in the activation of 4 oht based on the concentration gradients of soluble agonists emanating from the site of vascular injury, which has been excellently reviewed by Tomaiuolo et al.[1]. As part of the coagulation cascade, active thrombin is generated at

  2024-12-09

  

  In AD, and possibly other forms of dementia, it has been suggested that tau mislocalization to dendritic spines anticipates neurodegeneration [48]. Accumulation of hyperphosphorylated tau in dendritic spies would cause a derangement of synaptic function, thereby impairing excitatory synaptic transmi

  2024-12-09

  

  Curcumin is able to upregulate the protein level of NGF through cannabinoid receptor CB1, where the activation of Akt pathway probably plays an important part in the CB1-mediated signal transmission [9,10]. This finding suggested that the protection of curcumin in spinal motor neurons of SNI rats is

  Glioblastoma GBM is the highest-grade glioma (Grade IV) according to WHO classification and belongs to the most malignant form of pdtc tumor. It is an incurable disease despite the use of aggressive treatments that include surgery and radiotherapy, usually in combination with chemotherapy [13].

  Discussion Here, we show opposing effects of iontophoretically administered phenylephrine,aselective α1-AR agonist, on firing of putatively DAergic and non-DAergic neurons recorded in vivo in the VTA of urethane anaesthetized rats. Phenylephrine application caused a relatively weak decrease in fi

  In addition to the above-mentioned synaptic mechanisms, the serotonergic system also has a critical role in the antidepressant effects of mGlu2/3 receptor antagonists. Indeed, we previously reported that mGlu2/3 receptor antagonists increased the firing rate of serotonin neurons in the dorsal raphe

  Further evidence for ACh/GABA cotransmission had also been observed in the cortex. Extensive axonal arborization from cholinergic BF neurons exists throughout the cortical layers, allowing direct observation of cholinergic synaptic terminals. One study in the visual cortex of cat examined immunolabe

  However, although in vitro studies in heterologous systems have provided very important indications of potential novel pharmacology, the studies with endogenous receptors in native tissues are essential to provide evidence for GPCR heteromerization in vivo and to confirm its physiological relevance.
