  In modern science and technology, many optimization problems need to be solved in real time, while these classical methods cannot render real-time solutions to these optimization problems, especially large-scale problems. As a new metaheuristic, particle swarm optimization (PSO) [18], [19] has prove

  2020-09-07

  

  Since PTKs are involved in numerous aspects of cell function, their regulation is critical for cell survival and function. The carboxyl-terminal tyrosine of Src-family PTKs is a key site of regulation. Phosphorylation on this carboxyl-terminal tyrosine contributes to the induction of a conformationa

  In the present study we examined whether the gene for estrogen receptor alpha, Esr1, plays a role in the expression of maternal memory in female rats. The approach utilized a newly developed rat Esr1 knockout (KO) rat model (Rumi et al., 2014) to evaluate whether deletion of the Esr1 1-Oleoyl lysoph

  2020-09-07

  

  Estrogen treatment in postmenopausal women requires combination with a progestogen in order to prevent endometrial stimulation. This is not necessary, however, with tibolone as progestogenic activity is associated with its Δ4-metabolite that is formed in the liver, as well as locally in the endometr

  To our knowledge, this is the first report of an oncocytoma expressing alpha-enolase or causing autoimmune retinopathy and optic neuropathy. Although generally considered benign, oncocytomas have rarely been associated with paraneoplastic syndromes, including tumor-induced hypertension, erythrocytos

  A comparative analysis of the cleavage activity of different forms of the BoNT/A endopeptidase in reduced conditions with SNAPtide and full-length SNAP-25 substrate is summarized in Fig. 5, Fig. 6. The BoNT/A LC was found to be the most active against SNAPtide, a small peptide segment of the SNAP-25

  At present, there have been relatively few studies that evaluated potential correlations between pulmonary and pleura metastases, hilar and mediastinal Brilliant Blue G nodes, and organs associated with distant metastasis and EGFR mutations [33,34,37]. Further research on these relationships is need

  Taken together, these assays demonstrate that SUMOD positioning is essential for all E3 ligases but dispensable for E2 and S*E2 sumoylation reactions. Thus, we propose SUMOD positioning as a key criterion to describe the enzymatic function of SUMO E3 ligases that distinguishes them from other enhanc

  Materials and methods Results and discussion In the present work, we have applied two methodologies, CoMFA and CoMSIA to build 3D-QSAR models. There is no crystal structure available; therefore, an indirect method i.e., a ligand-based approach is the method of choice. The highly active molecul

  The new ESC guidelines incorporate data from a network meta-analysis of 100 studies confirming that new-generation drug-eluting stents (DES) improve survival compared with medical treatment, although this has not been demonstrated in any individual study.

  Introduction Cholesterol plays a pivotal role as a constituent of biological membranes and as a precursor for vitamins, hormones and bile acids. Accordingly, its production, distribution, and elimination must be tightly regulated at the cellular and organismal level. Accordingly, dysregulated chole

  There are a few visible DNA staining methods, which use dyes such as methylene blue, brilliant cresyl blue [7], crystal violet [8], Nile blue [9], [10] and ethyl violet [11]. However, although safe, these methods require long staining times, lack sensitivity and are not specific for nucleic acids.

  In contrast to the methylation that is catalyzed exclusively by DNMTs, there have been suggested several pathways that could induce demethylation (Watt & Molloy, 1988). However, the existence and influencing of enzymes that promote active demethylation remains elusive. Studies aiming to gain more in

  Introduction Although not fully understood, the molecular toxicology of sulfur mustard (bis(2-chloroethyl)sulfide, SM; CAS–Nr. 505-60-2), an alkylating warfare agent, has been attributed to DNA alkylation [1], [2], [3]. The same principle holds true for other alkylating compounds such as nitrogen
