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...
زمینه و هدف: ژن p4 لیشمانیا ماژور، در مرحله آماستیگوت انگل بیان می شود که احتمالاً ترکیب مناسب جهت تهیه واکسن بر علیه لیشمانیوز است. هدف از انجام این پژوهش، کلون این ژن در یک وکتور (ناقل) مناسب برای مطالعات بیشتر در زمینه واکنس سازی بود.روش بررسی: این بررسی به صورت تجربی انجام گرفته است. در مرحله پروماستیگوت، لیشمانیا ماژور در محیط n.n.n و سپس در محیط rpmi1640 به صورت انبوه کشت داده شد. در ادامه...
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...
P4 ATPases (subfamily IV P-type ATPases) form a specialized subfamily of P-type ATPases and have been implicated in phospholipid translocation from the exoplasmic to the cytoplasmic leaflet of biological membranes. Pivotal roles of P4 ATPases have been demonstrated in eukaryotes, ranging from yeast, fungi and plants to mice and humans. P4 ATPases might exert their cellular functions by combinin...
The concept of quaternary prevention (P4) refers to the idea that medicine has acquired the ability to damage through the proper exercise. Family medicine or general practice has the duty of recovering the ethical values and the exercise of a profession with the doctor-patient relationship serving to people’s humanity. In the fourth Congress of Family and Community Medicine, held in Montevideo ...
