A note on the fine structure constant

We derive the numerical value of the fine structure constant in purely number-theoretic terms, under the assumption that in a system of charges between two parallel conducting plates, the Casimir energy and the mutual Coulomb interaction energy agree

A case study of human hepatic hydatidosis and the biochemical Profile of cyst wall and fluid

The non specific haematological changes and negative Casoni's test suggest that ultrasonography is more reliable for the diagnosis and epidemiological stud­ies of human hydatidosis. The majo.r biochemical compo­nents like glycogen, proteins, nucleic acids, total lipids, triglycerides, cholesterol, free fatty acids and phospho­lipid fractions were analysed and compared with the other host's cysts. The differences were discussed in the light of strain variations in Echinococcus granulosus

Understanding the Formative Assessment: A Road Towards Targets Achievements

Learning is acclaimed to be a paramount and effective source of changing behavior across the world. To measure the behavior, there are techniques and skills to be learnt. Assessment in learning process enables the individual to examine the effectiveness of the various methods and techniques that the efforts are targeted or not and to see that the teachers, learners and instructional process in on the road to success. Formative assessment plays a decisive role to get the job done. The objectives of the study were to investigate the teachers’ perception about the usefulness of formative assessment in learning process and to get inform the educators about the worth of formative assessment process. All the working male teachers at primary, secondary, and higher secondary levels in District Mardan constituted the population of the study. Four hundred government school teachers for Boys were selected randomly as sample of the study. Among those 400 teachers, 300 were randomly selected for filling the questionnaire and 100 for conducting of informal interview. The collected data of the questionnaire was analyzed through percentages and inferential statistics i.e., chi-square by SPSS version 16. Themes, pattern were drawn and codification were made from the collected data of interviews. The study revealed that formative assessment is very effective and productive technique which plays a crucial role in boosting and stimulating instructional process.

Leishmanial Hepatitis with Chronic Hepatitis B Infection Treated Successfully with Liquid Form of Liposomal Amphotericin B - A Case Report

Hepatic involvement either due to leishmaniasis or due to coexisting viral infection sometime poses a problem for the clinicians. Atypical presentation is also challenging for them. We present a case of visceral leishmaniasis (Kala-azar) from a non endemic zone, co infection with hepatitis B virus simulating chronic viral hepatitis successfully treated with liquid form of liposomal amphotericin B.DOI: http://dx.doi.org/10.3329/bsmmuj.v5i1.11018 BSMMU J 2012; 5(1):55-56

New mitogenome and nuclear evidence on the phylogeny and taxonomy of the highly zoonotic tapeworm Echinococcus granulosus sensu stricto

Cystic echinococcosis, a zoonotic disease caused by Echinococcus granulosus sensu lato (s.l.), is a significant global public health concern. Echinococcus granulosus s. l. is currently divided into numerous genotypes (G1-G8 and G10) of which G1-G3 are the most frequently implicated genotypes in human infections. Although it has been suggested that G1-G3 could be regarded as a distinct species E. granulosus sensu stricto (s. s.), the evidence to support this is inconclusive. Most importantly, data from nuclear DNA that provide means to investigate the exchange of genetic material between G1-G3 is lacking as none of the published nuclear DNA studies have explicitly included G2 or G3. Moreover, the commonly used relatively short mtDNA sequences, including the complete coxl gene, have not allowed unequivocal differentiation of genotypes G1-G3. Therefore, significantly longer mtDNA sequences are required to distinguish these genotypes with confidence. The main aim of this study was to evaluate the phylogenetic relations and taxonomy of genotypes G1-G3 using sequences of nearly complete mitogenomes (11,443 bp) and three nuclear loci (2984 bp). A total of 23 G1-G3 samples were analysed, originating from 5 intermediate host species in 10 countries. The mtDNA data demonstrate that genotypes G1 and G3 are distinct mitochondrial genotypes (separated by 37 mutations), whereas G2 is not a separate genotype or even a monophyletic cluster, but belongs to G3. Nuclear data revealed no genetic separation of G1 and G3, suggesting that these genotypes form a single species due to ongoing gene flow. We conclude that: (a) in the taxonomic sense, genotypes G1 and G3 can be treated as a single species E. granulosus s. s.; (b) genotypes G1 and G3 should be regarded as distinct genotypes only in the context of mitochondrial data; (c) we recommend excluding G2 from the genotype list.
