Background: The sudden exposure of premature newborns to a cold and dry environment can lead to hypothermia. This study aimed at comparing the effectiveness of two polyethylene covers on the body temperature and oxygen saturation of premature neonates. Methods: This experimental study was conducted on 72 premature newborns in the neonatal int...

in this research, modification on the ultrafiltration (uf) membrane by synthesis of a thin layer of polyamide selective layer was designed for high performances of forward osmosis (fo) water treatment. two monomers, m-phenylenediamine (mpd) and trimesoyl chloride (tmc) with different concentrations of mpd (2.0% w/v and 1.0% w/v) were reacted with tmc (0.15% w/v) for interfacial polymerization (...

Experimental studies have been carried out to study the effect of various fillers on physicomechanical and tribotechnical properties compositions, optimal filler contents established, which ensure best polyethylene, polypropylene, polystyrol polyamide structural composite materials. The principle design shock-resistant, antifriction antifriction-wear-resistant materials is proposed. Highly effi...

Pyrrole-imidazole (PI) polyamide is a novel gene regulating agent that competitively inhibits transcription factor binding to the promoter of the specific target gene. Liver fibrosis is an integral stage in the development of chronic liver disease, and transforming growth factor β (TGFβ) is known to play a central role in the progression of this entity. The aim of this study was to evaluate the...

The fluorescence from tetramethyl rhodamine in hairpin polyamide tetramethyl rhodamine (TMR) conjugates is quenched in solution. TMR fluoresces brightly upon polyamide binding match DNA. Similar behavior is not observed in the presence of mismatch DNA; the hairpin polyamide-fluorophore conjugates therefore provide a smallmolecule fluorescent means for detecting chosen DNA sequences in homogenou...

Lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1) is a membrane protein that can support the binding, internalization, and proteolytic degradation of oxidized low-density lipoprotein. The LOX-1 expression increases in the neointima after balloon injury. To develop an efficient compound to inhibit LOX-1, we designed and synthesized a novel gene silencer pyrrole-imidazole (PI) polya...

Microplastics (MPs) affect plankton (a basis of the trophic chain) and planktivorous fish can ingest them through food confusion or by transmission. Consensus to determine MPs in is lacking and, so, three digestion treatments were evaluated: Alkaline (potassium hydroxide) enzymatic (protease plus lipase) digestions, both combined with a hydrogen peroxide stage; an oxidative method using surfact...
