This work examined teakwood and parawood in wood/poly(vinyl chloride) composite (WPVC) materials under UV-weathering seawater immersion. The mechanical properties as well anti-fungal anti-algal performance were considered. Teakwood (a rubberwood product) WPVC at ratios of 0:100, 20:80, 40:60, 50:50, 60:40, 80:20, 100:0 investigated. ageing periods 0 to 32 days immersion 90 studied. Aspergillus ...

Protective coating corrosion failure is a complicated process that involves various phenomena which are hard to test for separately. An adequately protected pipe can be in service for a relatively long time without exhibiting any signs of corrosion failure, and then all of a sudden it corrodes over a short period of time. Failure will definitely happen if the interface between the pipe surface ...

The anti-inflammatory and analgesic effects of the ethanolic extract (SLEE) and fruticulin A from the leaves of Salvia lachnostachys were evaluated in mice, using experimental models of inflammation (paw oedema and pleurisy induced by carrageenan injection) and hyperalgesia (electronic Von Frey). Oral administration of SLEE (30, 100, and 300 mg/kg) and fruticulin A (0.3 and 3.0 mg/kg) decreased...

statement of problem: the role of the microbial plaque in caries etiology and periodontal diseases has been proved and the mechanical methods for plaque control have special limitations, consequently, chemical methods have been suggested. one of the most effective materials is chlorhexidine gluconate that is commonly used as mouth rinses. however, the medicated formulations of chewing gums, due...

Background and Aim: Traumatic brain injury is one of the leading causes of mortality and disability in young adults. Epigallocatechin-3-gallate, the antioxidant compound of green tea, has been proposed to have antioxidant and anti-inflammatory properties. This study evaluates the potential effects of epigallocatechin-3-gallate on the early clinical outcome and serum S100B levels (biomarker for ...

due to good biocompatibility, corrosion and mechanical properties, magnesium (mg) is considered promising degradable material for orthopedic applications. in this work, mg-mgznx (x= 1, 2, 3 and 4) nanocomposites scaffolds with different porosities were synthesized via powder metallurgy method. the microstructure, composition, in vitro corrosion and mechanical properties of porous magnesium-zinc...

Mu-opioid agonists and N-methyl-d-aspartate (NMDA) receptor antagonists have been shown to attenuate mechanical allodynia in neuropathic pain models. We have previously reported that 2Hz electroacupuncture (EA) produced analgesia via releasing endogenous opioid peptides (i.e. beta-endorphin and endomorphin) and the activated micro-opioid receptors. The present study aimed to examine whether ket...

Background: Tolmetin (Tol) is a pyrrole acetic acid derivative that acts as a highly effective topical anti-inflammatory agent. Topical administration of Tol is effective for the management of ocular inflammations.The aim of this study was to formulate and improve a topical ophthalmic delivery system of Tol. Materials and methods: In the present study, ocular inserts of Tol were prepared using ...
