OBJECTIVES/HYPOTHESIS Enlarged vestibular aqueduct (EVA) and hearing loss are known to be caused by SLC26A4 mutations, but large phenotypic variability exists among patients with biallelic SLC26A4 mutations. Intrafamilial phenotypic variability was analyzed in multiplex EVA families carrying biallelic SLC26A4 mutations to identify the contribution of SLC26A4 mutations and other genetic or envir...

BACKGROUND As an alternative to electric vacuum aspirations (EVA), there is an increasing interest in using manual vacuum aspiration (MVA). OBJECTIVE To compare the safety, efficacy and acceptability of MVA with those of EVA for first-trimester abortion.

A dithiocarbamate chain transfer agent (CTA) based on Z-group substituted with a diphenyl amine (–NPh2) moiety is selected for the synthesis of statistical and diblock copolymers ethylene vinyl acetate via reversible addition–fragmentation polymerization. Benefiting from good growth control polyethylene (PE), poly(vinyl acetate) (PVAc), poly(ethylene-co-vinyl (EVA) achieved this CTA, linear typ...

Equine viral arteritis (EVA) is a contagious viral disease of equids caused by equine arteritis virus (EAV), an RNA virus that is classified in the family Arteriviridae. The virus is found in horse populations in many countries worldwide. EVA cannot be differentiated clinically from a number of other respiratory and systemic equine diseases.

There has been a significant increase in the number of facial fractures stemming from sport activities in recent years, with the nasal bone one of the most affected structures. Researchers recommend the use of a nose protector, but there is no standardization regarding the material employed. Clinical experience has demonstrated that a combination of a flexible and rigid layer of ethylene vinyl ...

OBJECTIVE To compare the efficacy, safety and cost-effectiveness of Manual vacuum aspiration (MVA) with Electrical vacuum aspiration (EVA) in the management of first trimester pregnancy loss. METHODS A single-centre randomized controlled trial (RCT) was conducted at Maternal and Child Health Centre (MCHC), Unit-I, Pakistan Institute of Medical Sciences (PIMS), Islamabad from April 2007-Dec 20...
