The ferroelectric (Sm C*)-antiferroelectric (Sm C*A)-reentrant ferroelectric (re Sm C*) phase temperature sequence was observed for systems with competing synclinic-anticlinic interactions. The basic properties of this system are as follows: (i) the Sm C* phase is metastable in the temperature range of the Sm C*A; (ii) the helix handedness inverts at both Sm C*-Sm C*A and Sm C*A-re-Sm C* phase ...

  Background: Sulfur mustard (SM) has acute and chronic effects on skin and mucosal surfaces. The aim of the study was to evaluate the frequency of esophagitis in a historical cohort of veterans who had been exposed to SM in Iran-Iraq war nearly 25 years ago.   Methods : One hundred two veterans with dyspepsia and/or heartburn underwent esophago-gastro-duodenoscopy. Of them, 52 cases had been e...

Sulfur Mustard (SM) is a chemical warfare agent which was widely used in the World War I and more recently during Gulf war in the early 1980s'. SM is a strong alkylating agent with known mutagenic and carcinogenic effects but only few studies have been published on its teratogenicity. Since SM has been widely used as a chemical weapon by the Iraqi regime against the Iranian soldiers as well as ...

normal 0 false false false en-us x-none ar-sa background : the beneficial effects of lactobacillus species have been reported but the role of these species including lactobacillus casei (l.casei) on oral health is not well documented. the purpose of this study was to evaluate the effects of conventional or probiotic cheese containing l.casei on salivary streptococcus mutans (sm) and lactobacill...

A study on evapotranspiration for wheat was conducted in the two-year Rabi season crop from November, 2017 to April, 2018 and April 2019 at Gaya District, Bihar. Spatio-temporal information actual (ETa) helps users better understand evaporative depletion establish links between land use, water allocation, use. The Surface Energy Balance Algorithm Land (SEBAL) adopted employing essential adaptat...

Sphingomyelin (SM) levels in the circulation correlate positively with atherosclerosis burden. SM is a ubiquitous component of human diets, but it is unclear if dietary SM increases circulating SM levels. Dietary choline increases atherosclerosis by raising circulating trimethylamine N-oxide (TMAO) levels in mice and humans. As SM has a choline head group, we ask in this study if dietary SM acc...

  Objective(s): Soluble Leishmania antigens (SLA) provide suitable protection against leishmaniasis in murine model when delivered by an appropriate delivery system. Liposomes have been shown to be suitable vaccine delivery systems against leishmaniasis, however, the phospholipase-A (PLA) activity of SLA is a drawback to prepare a stable liposomal SLA. One strategy to overcome this problem migh...
