Alterations in mitochondrial permeability transition and organelle damage are key players in the development of cerebral ischemic tissue injury due to associated modifications in ATP turnover and cellular apoptosis/necrosis. Early restoration of blood flow and improvement of mitochondrial function might reverse the situation and help in recovery following an onset of stroke. Mitochondria and re...

The integrity of sperm progesterone (P4) receptor(s) and its response to steroid stimulation might be crucial for the maintenance of sperm fertilizing ability after cryopreservation. The aim of the current investigation was to study the effect of cryo-procedures on canine sperm P4 receptor(s). In addition, alteration of P4 receptor(s) at the molecular level and their functional integrity follow...

Research concerning new targeting delivery systems for pharmacologically active molecules and genetic material is of great importance. The aim of the present study was to investigate the potential of fourth generation (P4) cationic phosphorus-containing dendrimers to bind fluorescent probe 8-anilino-1-naphthalenesulfonate (ANS), anti-neoplastic drug cisplatin, anti-HIV siRNA siP24 and its capab...

Bacteriophage phi29 protein p4 is essential for the regulation of the switch from early to late phage transcription. The protein binds to two regions of the phage genome located between the regulated promoters. Each region contains two inverted repeats separated by 1 bp. We used circular permutation assays to study the topology of the DNA upon binding of the protein and found that p4 induced th...

Membrane-bound HLA-G (mHLA-G) discovery on adipose derived stem cells (ADSCs) as a tolerogenic and immunosuppressive molecule was very important. Many documents have shown that HLA-G expression can be controlled via some hormones such as progesterone (P4) and estradiol (E2). Therefore, this study was designed to evaluate progesterone and estradiol effects on mHLA-G in ADSCs at restricted and co...

The bacteriophage Ø29 transcriptional regulator p4 binds to promoters of different intrinsic activities. The p4-DNA complex contains two identical protomers that make similar interactions with the target sequence 5'-AACTTTTT-15 bp-AAAATGTT-3'. To define how the various elements in the target sequence contribute to p4's affinity, we studied p4 binding to a series of mutated binding sites. The bi...

The essential role played by progesterone in the maintenance of pregnancy is unequivocal; however, the effects of progesterone on the secretory patterns of placental and pituitary molecules during the gestation period are not well defined. The objective of this study was to describe pregnancy-associated glycoprotein (PAG) concentrations (measured by RIA-497 and RIA-Pool) in pregnant females wit...

PURPOSE The objective of this study was to evaluate the influence of propiverine-HCl (P4) and propiverine-N-oxide (P4NO), one of the major metabolites of P4, on bladder contraction in a standardized in vivo model. Additionally, salivary flow measurements enabled the evaluation of hyposalivation, one of the most predominant anticholinergic side effects. MATERIALS AND METHODS Ten male mini pigs...

Software-defined networking (SDN) architecture has provided well-known advantages in terms of network programmability, initially offering a standard, open, and vendor-agnostic interface (e.g., OpenFlow) to instruct the forwarding behavior devices from different vendors. However, last few years, data plane programmability emerged as promising approach extend management allowing definition progra...
