calcium hydroxide is the most widely used intracanal medicament in endodontics, which should be removed prior to permanent root canal filling to minimize its intervention with the bonding of endodontic sealers. this ex-vivo study aimed to evaluate the effect of pretreatment with calcium hydroxide on the bond strength of resilon/epiphany self etch (se) to the radicular dentin after removing the ...

ten chromite ores from ophiolite complexes in se iran were analyzed mineralogically by xrd, chemically by xrf, and mineral chemistry by epma. the identified paragenesis of silicate minerals of chromite ores with the x-ray diffraction is pronounced differently. it consists of secondary phases formed as serpentine, cr-containing chlorite (kaemmererite), chromic garnet (uarovite) with preserved pa...

let $g$ be a group and $h$ a subgroup of $g$‎. ‎ $h$ is said to have semi-$pi$-property in $g$ if there is a subgroup $t$ of $g$ such that $g=ht$ and $hcap t$ has $pi$-property in $t$‎. ‎in this paper‎, ‎investigating on semi-$pi$-property of subgroups‎, ‎we shall obtain some new description of finite groups‎.

Specification of the context in which the system will operate, the purposes of the system, what operations the system must perform, and what quality of service the system must provide in achieving those purposes and rendering those services. A statement of properties that a system shall exhibit or shall not exhibit when completed. Note: requirements are derived from requirements in a many-to-ma...

background: selenium (se) is an essential trace element mainly obtained from seafood, meat, and cereals. se deficiency has been identified as a major contributing factor in the pathogenesis of certain congestive heart failure (chf) syndromes. since there is controversy over the prevalence of se deficiency among patient with chf, the aim of this study was to assess the serum se concentrations in...

conclusions se supplementation can increase plasma se concentration and rbc gsh-pxs activity in patients with different stages of ckd. background plasma selenium (se) concentration and glutathione peroxidase (gsh-pxs) enzyme activity of the patients with chronic kidney disease (ckd) are usually lower than healthy individuals; however, the effect of se supplementation on the gsh-pxs activity in ...

The Tsunami in 2004 devastated Sri Lanka. In its aftermath, followed aid and support from multiple sources. As countries in South Asia ready themselves for climate change and the possibility of increased frequency in natural disasters, it is useful to understand how well post disaster operations work to help victims. It is vital that a country’s post-disaster development aid is well targeted an...

La carga de diazepam ha demostrado ser un tratamiento válido para la abstinencia alcohólica en ensayos controlados aleatorizados. Tras una búsqueda bibliográfica no sistemática, no hemos encontrado antecedentes en la litera...

Bacillus velezensis OSY-S3 produces anti-Listeria, anti-Escherichia coli, and antifungal compounds. Additionally, fermentate of B. velezensis OSY-S3 culture removes Staphylococcus aureus biofilms effectively. The draft genome sequence of B. velezensis OSY-S3 reported here had a genome size of ~3.90 Mb and a G+C content of 46.5%.
