Inhibition of blood group antibodies by soluble substances

Background When performing pretransfusion testing, serologic results may indicate the presence of one or more alloantibodies. There are many methods that can be used to identify and separate specificities.1 One such method is based on the principle of inhibition. The ability to specifically inhibit one antibody may help identify that antibody and allow other antibody specificities to also be identified. Inhibition can aid in the identification of an antibody to an antigen that shows variable

BIOLOGICALLY-INSPIRED SIGNAL PROCESSOR USING LATERAL INHIBITION AND INTEGRATIVE FUNCTION MECHANISMS FOR HIGH INSTANTANEOUS DYNAMIC RANGE

This paper presents a biologically-inspired signal processor, which allows selective amplification of signals, and signal channeling mechanism to increase the contrast and sharpness of the perceived signals. The processor draws influence from lateral inhibition and integrative function mechanisms of the human nervous system. The uniqueness of the proposed design is that it combines two intelligent signal transmission mechanisms of the human nervous system with desirable capabilities: 1) wide

Temporal specificity of latent inhibition in rats with daily water restriction prior to taste conditioning

INTRODUCTION The formation of latent inhibition (LI), that is a reduced conditioned response due to pre-exposures to the future conditioned stimulus (CS) before conditioning, is sensitive to certain contextual changes between different stages in the procedure (Hall and Channell, 1986; Escobar et al., 2002). Particularly, LI of taste aversion learning (CTA) can be modulated by contextual changes to the external or physical environment (De la Casa and Lubow, 1995; 2001; Lukoyanov et al., 2002

Evaluation of monoclonal anti-A reagents by salivary inhibition studies

Ten commercially available monoclonal and polyclonal anti-A reagents were evaluated for use in the test for ABH secretor status after finding unexpected inhibition with a monoclonal anti-A (reagent Z). Two of the available monoclonal reagents were from different batches from the same clone as reagent Z. Those two reagents, as well as reagent Z, appeared to he partially neutralized by salivary substances from group A nonsecretor individuals. This finding suggests that when a saliva inhihition

Poor inhibition leads to intruding of irrelevant information into WM and reduces its capacity (Vogel and Machizawa, 2004; Borella, 2008). The inhibition is also critical for a situation in which multiple stimulus-response (S-R) associations (S-R mappings) or task sets should be maintained in WM and compete with each other for an access to a motor response.

concerning growth inhibition of other bacteria (Enterococcus spp.) and yeast (Candida albicans) by nanosilver is also available (Kim et al. 2007; Roe et al. 2008; Lara et al. 2015). However, the studies of AgNPs interaction with cell structures of bacteria and yeasts are scarce. Only in few reports the location of AgNPs inside C. albicans cells was demonstrated under transmission electron microscopy (TEM) or scanning electron microscopy (SEM) (Kim et al. 2009; Radhakrishnan et al. 2018).

CRESOLS AND THE MICROORGANISMS OF THE SOIL ENVIRONMENT

bring about changes in the structure of their cell membranes, resulting in their growth inhibition and cell lysis. However, there is still an untapped bioremediation potential in microorganisms, which are able to participate in the catabolism of cresols, both under aerobic and anaerobic conditions. The typical strategies of the aerobic degradation of cresols include the use of monooxygenase and dioxygenase enzymes. Thanks to these enzymes, atoms of molecular oxygen initiate fission of the aromatic

Fon resulted in shorter vine lengths than treatment with either P. fluorescens isolate plus RKN. Root weights, galling indices, eggs per gram root, and secondstage juvenile (J2) numbers in soil were similar among all RKN-inoculated treatments, and fruit production was not affected by treatment. Plant death was high in all treatments. These studies demonstrated that the tested P. fluorescens isolates resulted in some inhibition of vine growth in the field, and were not effective for enhancing plant

Hindbrain metabolic deficiency regulates ventromedial hypothalamic nucleus glycogen metabolism and glucose-regulatory signaling

glycolytic end-product L-lactate is monitored in the hindbrain as a critical metabolic variable. The astrocyte-neuron lactate shuttle hypothesis posits that astrocyte lactate trafficking sustains mitochondrial energy production in neurons (Broer et al., 1997; Pellerin et al., 1998; Magistretti et al., 1993). Pharmacological induction of lactoprivation within the DVC, involving inhibition of local monocarboxylate transporter function, is a potent stimulus for hyperglycemia (Patil and Briski, 2005).

Diazepam and electrical stimulation of paleocerebellar cortex inhibits seizures in pentylenetetrazol-kindled rats

These data point to the potential for the development of new and better therapies for drug-resistant seizures (Asgari et al., 2014, 2016). This study presents the first analysis of BDZ-GABAA-dependent mechanisms of seizure inhibition in response to paleocerebellar ES. To test this, we used the PTZ-induced kindling rat model since PTZ is a selective antagonist of the GABAA receptor-chloride ionophore complex (Erkec and Arihan, 2015

To build on previous research in this field, experiments were designed to determine if previously documented synaptic dysfunction in AD models is concomitantly observed with excitation/inhibition imbalance as suggested by observation of seizure and seizure‑like pathology in such models. We report changes in synaptic function in aged APPPS1 mice not observable in the younger cohort. These changes in synaptic function are furthermore accompanied

In the observation period, LPS induced CCL3/MIP‑1alpha expression, which localized to OX‑42‑labeled microglia, leading to time‑dependent increases in the phosphorylation of P38 MAPK and ERK1/2. The expression pattern of induced CCL3/MIP‑1alpha was partly consistent with the phosphorylation of MAPKs (P38 MAPK, ERK1/2). Anti‑MIP‑1alpha attenuated microglial accumulation and the upregulation of cyclooxygenase‑2 and iNOS. The inhibition of P38 MAPK, ERK1/2, or NF‑kappaB signaling reduced the

Antiepileptic drugs as a new therapeutic concept for the prevention of cognitive impairment and Alzheimer’s disease. Recent advances

Introduction. Excessive accumulation of amyloid-beta (A_) peptides in the brain results initially in mild cognitive impairment (MCI) and finally in Alzheimer’s disease (AD). Evidences from experimental and clinical studies show that pathological hyperexcitability of hippocampal neurons is a very early functional impairment observed in progressive memory dysfunctions. Therefore, antiepileptic drugs (AEDs) whose mechanism of action is aimed at inhibition of such neuronal hyperexcitability

phosphorylations take place with the participation of cellular kinases. The active drug form, ganciclovir triphosphate (GCV-TP), is a substrate for the viral DNA polymerase. Therefore, the antiviral effect results from the inhibition of the viral DNA synthesis in the mechanism of the competitive incorporation of the deoxyguanosine triphosphate into the DNA chain [14, 16, 19]. Ganciclovir is structurally similar to acyclovir; however, the introduction of an additional hydroxyl group has expanded the drug
