conclusions there was no significant lower recurrence rate of constipation with peg and lactulose combination therapy over peg alone. therefore, changing treatment from lactulose plus peg to peg alone would result in better compliance of patients for long-term therapy and would be cost effective. results the response rate to treatment was 70% in group i and 87% in group ii (p value 0.003). recu...

abstract background: after the umbilical cord is cut, premature neonates face numerous problems including hypothermia. with regard to serious complications of hypothermia and incapability of conventional methods in preservation of neonates’ temperature after admission, the researcher decided to conduct a study on the effects of two polyethylene covers in prevention of hypothermia among prematur...

More than 60.000 hip arthroplasty are performed every year in Italy. Although Ultra-High-Molecular-Weight-Polyethylene remains the most used material as acetabular cup, wear of this material induces over time in vivo a foreign-body response and consequently osteolysis, pain, and the need of implant revision. Furthermore, oxidative wear of the polyethylene provoke several and severe failures. To...

An efficient and green procedure for the synthesis of 2, 4, 6-triaryl-1H-imidazole in polyethylene glycol under microwave irradiation in excellent yield has been developed. Polyethylene glycol is non toxic, reusable, inexpensive and easily available.

A new concept is introduced in this study, suggesting the role played by ZnO crystal sulfur crosslinking polymers, particularly, rubber blends of EPDM-CTS. The study conducted a polymer blend ethylene propylene diene terpolymer (EPDM) and cyclic tetrasulfide (CTS). CTS reactive low molecular weight polymer, which can act as donor. It proposed that occurs at surface crystals. reaction site creat...

This study evaluated the insecticidal activity of garlic, Allium sativum Linnaeus (Amaryllidaceae) essential oil and their principal constituents on Tenebrio molitor. Garlic essential oil, diallyl disulfide, and diallyl sulfide oil were used to compare the lethal and repellent effects on larvae, pupae and adults of T. molitor. Six concentrations of garlic essential oil and their principal const...

Reduction of N2 to ammonia in nature and in electrocatalysis takes place through 1-proton/1-electron steps, motivating efforts to experimentally study the steps during proton/electron transfer to well-characterized N2-derived species with bridging nitrides. We report here the protonation and reduction reactions of an N2-derived iron bis(nitride) complex (Rodriguez et al., Science, 2011, 334, 78...
