  Detailed analysis of the dose dependence of Aβ effects revealed that at low amounts, Aβ can also act as a positive regulator of presynaptic activity, enhancing the neurotransmitter release probability and increasing the neuronal excitability [2]. The facilitator effects of low Aβ dose on excitatory

  Evidence shows that glial activation increases the expression of cytokines and chemokines in Parkinson's disease, which precede the degeneration of the substance nigra (Halliday and Stevens, 2011, Tansey and Goldberg, 2010). The use of non-steroidal anti-inflammatory drugs (except aspirin) can preve

  2024-06-07

  

  The metabolism of amino acids into volatile aldehydes involves both decarboxylation and deamination steps. The order of these reactions and the enzymes performing the catalysis differ among plants [13]. In tomato fruit the conversion of L-Phe to 2-phenylethanal is catalyzed by two enzymatic steps, i

  2024-06-07

  

  It was also shown that 15% of crizotinib resistance mechanisms can be due to an amplification of ALK gene while 30% are caused by a variety of secondary mutations (S1206Y, G1202R, L1196M, C1156Y, G1269A, L1152R, F1174L and 1151Tins) in ALK tyrosine kinase. These mutations can modify the conformation

  Targeted disruption of the Akt1 gene in mice induces a growth retardation phenotype [4,19]. Akt2 KO mice reveal mild growth retardation and insulin resistance [4,20,21]. Akt1/2 double KO (DKO) mice display severe growth deficiency and die shortly after birth. These mice exhibit impaired bone and ski

  2024-06-07

  

  Interaction between AhR and ligands leads to AhR transformation (Fig. 1), characterized by a rapid receptor nuclear translocation and the formation of AhR/Arnt complex and the release of the chaperone proteins. Following AhR transformation, the AhR/Arnt complex binds to its cognate DNA consensus seq

  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

  We also demonstrate that PACAP treatment dose-dependently disrupts performance in the 5CSRTT, suggestive of attentional deficits, another core feature of mood and anxiety disorders. Treatment with PACAP (.5–1.0 µg) decreased the percentage of correct responses, increased the percentage of trials in

  Introduction Fungi are an inexhaustible source of natural products mainly due to their wide distribution in the nature, estimated to range from 1.5 to 5.1 million species in the world [1]. Secondary metabolites from fungi represent a substantial fraction of drugs and drug models in pharmaceutical

  The hippocampus is the primary brain structure involved in learning and memory. The role of hippocampal synaptic plasticity in neurological processes in cognition and depression has been extensively demonstrated. Synaptophysin is a critical substance in synaptogenesis, which is necessary for learnin

  The central problem in amnesia developing following impairment of long-term memory consolidation or reconsolidation is a question of the underlying mechanisms, whether it is caused by impairment of retrieval or memory storage mechanisms [3,8,9,[15], [16], [17], [18]]. To answer this question, severa

  Drug resistance development often involves structurally un-related drugs and, specifically both conventional and targeted agents.

  Skeletal pain associated with bone fracture is another area of critical need for a novel pain medication. NSAIDs and opiates are the two major therapies currently used to manage bone fracture pain. However, both of these therapies lead to significant unwanted side effects. Using the osteotomy model

  The surprising finding of our study is that human M1 macrophages stimulated by LPS express ALOX15B to high levels. So far 12/15-lipoxygenase activity was only reported for IL-4 stimulated anti-phlogistic M2 macrophages [9] but not for the classically activated M1 macrophages. Our data suggest that s
