  We have previously shown that the antinociceptive effect of tramadol, an analgesic that, like paracetamol is able to increase serotonin levels within CNS, is potentiated or antagonized respectively by a 5-HT1A/B nonspecific bgj blockade or activation (Rojas-Corrales et al., 2000). Moreover, it has b

  2024-03-30

  

  Salivary α-amylase activity was not significantly different between bitches with pyometra and healthy bitches, and there were no significant changes after ovariohysterectomy, similar to chromogranin A (Jitpean et al., 2015). Therefore, it is postulated that the SAM axis is not activated in bitches w

  2024-03-30

  

  The biological characteristics of cancer invasion and metastasis are mainly attributed to the poor prognosis in cancer. It has been reported that overexpression of Ack1 promoted the migratory and invasive properties of breast cancer 3965 by sustaining expression of epidermal growth factor. In contra

  At present, the role of autophagy in neurons remains controversial. Autophagy has homeostatic and waste-recycling functions and plays a protective role in neurodegeneration diseases. Moreover, it has been thought as a programmed cell death participating in the occurrence and development of various d

  Material and methods Results Discussion Although we were not able to detect 12/15-LOX mRNA in the lungs of 12/15-LOX knockout mice substantial amounts of 15-HETE could be detected in BALF. In fact, significant synthesis of 15-HETE in 12/15-LOX mice have been already reported [17]. The redun

  2024-03-29

  

  From an historical perspective, ligands for GPCRs (adrenaline, serotonin, SJB3-019A or morphine, to name a few) have been identified before their receptor counterparts, at a time when the concept of receptor itself was controversial [15]. Although many cognate receptors for endogenous ligands were

  Discussion Arginase 1 and Arginase 2 are homologous enzymes that consume l-arginine to produce l-ornithine and urea [14], [15]. These enzymes compete with NO synthases for the same substrate [14], [15], [30], and therefore may reduce NO production [21], [24], [30]. The colocalization of arginases

  The efficacy of monensin in improving smell function has been previously found to be negative, both when used for bacterial and viral infections. Van Zele et al, in a double-blind, placebo-controlled, multicenter study, found no influence of doxycycline treatment on self-reported olfactory loss in

  2024-03-29

  

  MSG model is well characterized and widely used because it is not influenced by dietary components and because it mimics a lesion in the arcuate nucleus and lateral hypothalamus that can occur in chronic obese patients (Moraes et al., 2009, Purkayasta and Cai, 2013). High fat fed diet is amongst the

  In pancreatic islets we found an increase in protein expression of leukocyte 12/15-LO that paralleled the metabolic decline characterized by severe hyperglycemia and reduced islet numbers. Similar increase in 12/15-LO expression by Western blot was found in the control mice, which have a normal meta

  Stress/glucocorticoids as risk factor for Alzheimer’s Disease: preclinical studies A role for glucocorticoids in shaping the risk for AD is supported by animal studies using rats or mice injected with Aβ oligomers, tau protein or excitotoxins, or transgenic (Tg) mice carrying mutations associated

  It is important to note that stable amnesia is, apparently, a general biological phenomenon and can be found in different animal species. In studies on rats, it was found that if reconsolidation of conditioned olfactory aversion memory was impaired by the antagonist of NMDA glutamate receptors, amne

  In this article, we have outlined the increasing, as yet still circumstantial evidence that the 6TM domains of bacterial ACs might operate as receptors for as yet unknown ligands. Intriguingly, several architectural arguments are also applicable to the 6TM domains of mammalian membrane-bound ACs (mA

  Adenosine is a ubiquitous homeostatic substance released from most cells, including neurons and glias. Endogenous adenosine acts at four principal G-protein-associated receptor subtypes: A1, A2a, A2b and A3 (Ralevic and Burnstock, 1998). The stimulation of adenosine receptors by extracellular adenos

  Conclusions Several lines of evidence have been established, which support the adenosine kinase hypothesis of epileptogenesis, which is based on a sequence of events leading from acute secretin receptor injury to initial downregulation of ADK, rise in extracellular adenosine, changes in astrocyt
