In [1] we studied normal, rational -varieties X of complexity one, where the latter means that X comes with an effective torus action such that holds. We showed that for affine X with and at most log terminal singularities, the iteration of Cox rings is possible. In the present article, we charac

Introduction The endeavor to achieve a successful use of commercial-off-the-shelf (COTS) electronic devices in space is not new and the reasons are well known [1], [2], [3]. More recently, COTS have been widely employed in the manufacturing of low-cost, small satellites, for scientific and even c

Although the presence of at least one triple helix domain is typically the collagen signature, collagens are modular proteins composed of a succession of collagenous (COL) and non-collagenous domains (NC) that are both involved in collagen functions and in receptor binding. COL domains are linked by

To simulate the inhibition of the enzyme by organophosphorus, carbamate insecticides or nerve agents, a reversible cholinesterase inhibitor physostigmine was used for most experiments for safety reasons. However, the results of the measurements were verified using the soman organophosphate, which is

Materials and methods Results To investigate the effect of 17βE on cell proliferation in the human renal tubular epithelia, BrdU uptake was measured in HRTEC primary and 3D-HRTEC cultures, allowing determination of the DNA replication rate. Representative microphotographs show BrdU uptake in H

2020-08-21
Both progesterone and the calcium ionophore A23187 rely on the synthesis of cAMP by sAC to elicit exocytosis in human sperm (Fig. 2E-H and [8], [60]). We had reported earlier that digestion of endogenous cAMP with recombinant cAMP-specific phosphodiesterase 4D [9] or inhibition of its synthesis with

Then, we explored the MCLEIA methodology parameters including precision, accuracy and specificity. In the 0.5–128 ng/mL, the standard curve equation was = 0.5014 + 1.769 ( was log, was RLU/RLU with a correlation coefficient of 0.9907) (). On the one hand, same sample (0.5, 4.0, 32.0 ng/mL) detected

The IP3R is a ubiquitously expressed Ca2+-release channel from the ER, activated by IP3, produced upon cellular stimulation by hormones, growth factors or neurotransmitters. Three genes are coding for the IP3R and their gene products (IP3R1, IP3R2, IP3R3) assemble in functional homo- or heterotetra

Among prostaglandins (PG), PGD2 remained the most elusive species for a long time and was initially regarded as having negligible biological activity [1]. In 1974 its inhibitory effect on platelet aggregation was discovered by Smith et al. [2] and Mills & McFarlain [3], and both pressor and depresso

Although many neurotransmitters (e.g., catecholamines, serotonin, and excitatory/inhibitory amino acids) have been implicated in the modulation of anxiety-like responses (Carobrez et al., 2001, Molchanov and Guimaraes, 2002, Vianna et al., 2001), the so-called atypical neurotransmitters, endocannabi

The in vitro cytotoxicity of the prodrugs was assessed in the LS174T human colon cell line (). The results were found to reflect the stability of the prodrugs, with the unstable urea compounds ( and ) giving relatively poor cytotoxicity differentials between prodrugs and parents (i.e., approximately

Several studies have already shown that mPR activation can significantly reduce intracellular cAMP levels in different kind of cells, such as GT1-7 neuronal cells [32], MDA-MB-468 breast cancer cells [55] and primary vascular endothelial cells [56]. The experiments performed with PTXa and 8-Br-cAMP

One possibility to differentiate between the two failure modes, and also to identify the corresponding characteristics of the resulting fracture surface, is a series of FNCT measurements with varying nominal (initial) stress. The dependence of the observed time to failure tf on the actual stress cha

Calcium dependence of CaM target
2020-08-19
Calcium dependence of CaM/target interaction was analyzed using a titration matrix in which both Ca2+ and CaM concentrations were changed. This gave us access to different parameters characterizing the interaction and namely to the number of bound Ca2+ required for the interaction to occur. Our app
