Microplastics(MPs)are synthetic contaminants that have received global attention due to their ubiquitous occurrence,extreme durability,and capacity to harm ecosystems and human *** study investigated the occurrence of MPs in three fish species(Channa striata,Puntius sophore and Anabas testudineus)collected from two locations(Ashulia Bridge and Mirpur Road)of the Turag River,which flows alongside the Dhaka city,*** abundance(items/individuals)was highest in Channa striata(3.8±0.6)from the Ashulia Bridge area and lowest in Puntius sophore(1.8±0.4)from the Mirpur Road *** was found to be the most dominant(89e93%)form of MPs followed by fragments(21 e35%),films(0e26%)and foams(0e5%).The dominant color of MPs was blue(69e83%),then red(20 e33%),black(11e14%),green(8e20%),and purple(6e8%).The majority(56e71%)of the MPs assessed werefollowed by 0.5e1.0 mm(29e33%)and 1e5 mm(38e53%).ATR-fTIR examination revealed three specific polymer varieties-PP(40%),PS(30%)and LDPE(30%).The results of this study provided a baseline of MPs pollution in one of the major protein sources freshwater fishes and raised concern on public health particularly who consume fishes from the urban waterways.

AIM: To evaluate cladribine [2-chlorodeoxyadenosine (2-CdA)] therapy in refractory celiac disease (RCD) Ⅱ. METHODS: An open-label cohort-study of RCD Ⅱ patients treated with 2-CdA was performed between 2000 and 2010. Survival rate, enteropathy associated T-cell lymphoma (EATL) occurrence, clinical course, and histological and immunological response rates were evaluated. RESULTS: Overall, 32 patients were included with a median follow-up of 31 mo. Eighteen patients responded well to 2-CdA. Patients responsive to 2-CdA had a statistically significant increased survival compared to those who were unresponsive. The overall 3- and 5-year survival was 83% in the responder and 63% and 22% in the non-responder group, respectively. The overall 2-year clinical, histological and immunological response rates were 81%, 47% and 41%, respectively. Progression into EATL was reported in 16%, all of these patients died. CONCLUSION: Treatment of RCD Ⅱ with 2-CdA holds promise, showing excellent clinical and histological response rates, and probably less frequent transition into EATL.

In this paper, the semi-discrete entropy conditions with so called the proper discrete entropy flux of a class of high resolution MUSCL type schemes are discussed for genuinely nonlinear scalar conservation laws. It is shown that the high resolution schemes satisfying such;semi-discrete entropy conditions cannot preserve second order accuracy in the rarefaction region.

AIM To assess the relationship between gastric acid output (GAO) and both pattern of gastroesophageal reflux (GER) and esophageal lesions, and to evaluate the role of GAO and other potential pathogenetic factors in the development of esophagitis. METHODS Gastric acid secretory testing and 24 h intraesophageal pH monitoring were performed in 31 patients with esophagitis and concomitant duodenal ulcer (E+DU) and compared with those of 72 patients with esophagitis (E) alone. RESULTS The GAO in patients with E+DU was significantly higher than in patients with E ( P ficant difference between the two groups of patients as to endoscopicl findings and parameters of GER ( P >0 05). A multiple regression analysis with stepwise deletion showed that the pre sence of hiatal hernia (HH), GER in upright position and age appeared to correlate significantly with the presence of esophagitis. CONCLUSIONS No parallel relationship between GAO and severity of GER or esophageal lesions exists in patients with E+DU, and that GAO is not a major pathogenetic factor in GER disease.

Submergence tolerant high yielding rice variety was developed using BR11 as a recipient parent applying foreground, phenotypic and background selection approaches. Recombinant selection was found essential to minimize linkage drag by BC2f2 generation. Without recombinant selection, the introgression size in the backcross recombinant lines （BRLs） was approximately 15 Mb on the carrier chromosome. The BRLs were found submergence tolerance compared to the check varieties under complete submergence for two weeks at Bangladesh Rice Research Institute, and produced higher yield compared to the isogenic Subl-line under controlled submerged condition. The BRL IR85260-66-654-Gaz2 was released as BRRI dhan52 in 2010, which was the first high yielding submergence tolerant variety in Bangladesh. BRRI dhan52 produced grain yield ranging from 4.2 to 5.2 t/hm2 under different flash flood prone areas of Bangladesh in three consecutive seasons. The study demonstrated the efficiency of recombinant selection and better adaptability of the newly released submergence tolerant high yielding variety in flash flood prone different areas of the country with respect to submergence tolerance and yield potential.

Abstract: The α,β-unsaturated γ-lactones of neo-clerodane diterpenoids teucvidin, teupernin E and ajugacumbin A were selectively transformed into saturated γ-lactones and unsaturated diol derivatives with NaBH4. These transformations are of interest due to their selective reduction as compared with catalytic hydrogenation and LialH4 reduction of these diterpenoid compounds.

A mechanism for the catalytically growth of vapor grown fibrous carbon (VGfC) preparing from the floating catalyst method has been proposed, in which liquid diffusion-determined diffusion of carbon atoms through catalyst particles is described mathematically, and the physical and chemical properties of the catalyst particles during the growth process are taken into account. from the model the growth rate and grown length of VGfC are calculated theoretically which coincides with the experimental data; and the necessity of reducing gas such as hydrogen in preparing VGfC is explained as to reduce fe3C, which acts as intermediate catalyst shown by the model. fe3C formed on the surface of gamma-fe will stop the growth of carbon fiber if they can not be reduced at once. Additionally, the growth temperature and diameter of VGfC are also discussed in the paper.
