Although thyroid dyshormonogenesis (TDH) accounts for 10-20% of congenital hypothyroidism (CH), the molecular etiology of TDH is unknown in Bangladesh. Thyroid peroxidase (TPO) is most frequently associated with TDH and the present study investigated the spectrum of TPO mutations in Bangladeshi patients and analyzed the effects of mutations on TPO protein structure through in silico approach. Sequencing-based analysis of TPO gene revealed four mutations in 36 diagnosed patients with TDH including three nonsynonymous mutations, namely, p.Ala373Ser, p.Ser398Thr, and p.Thr725Pro, and one synonymous mutation p.Pro715Pro. Homology modelling-based analysis of predicted structures of MPO-like domain (TPO142-738) and the full-length TPO protein (TPO1-933) revealed differences between mutant and wild type structures. Molecular docking studies were performed between predicted structures and heme. TPO1-933 predicted structure showed more reliable results in terms of interactions with the heme ...

Clavibacter xyli subsp. cynodontis (Cxc) is a xylem-inhabiting bacterial endophyte of Bermudagrass. This organism is classified with Gram-positive, high G + C content, coryneform-actinomycete bacteria. Southern-blot analysis showed that Cxc contains only one copy of the ribosomal RNA-encoding genes (rRNA). A clone containing the rRNA genes was isolated from a genomic library of Cxc DNA cloned in the lambda EMBL3 vector. The gene cluster was partially sequenced, revealing the gene order 5'-16S-23S-5S-3', similar to that found in other prokaryotes. Low-resolution S1 mapping suggested multiple transcription start points of the rRNA operon.

This study concentrates on dissolution of drug in presence of fruit juice specifically mango juice. This work aspires current research to study the dissolution approach pattern of commercial formulation of metronidazole in Bangladesh commercially available eight brands of metronidazole film coated tablets were studied in gastric medium (pH 1.2). All brands got reasonably higher dissolution release mainly M02 (84.79%), M05 (75.86%), M06 (72.53%) and M07 (86.48%) were released relatively faster than other sample in 15 to 50 minutes. Therefore, Mango juice assists to enhance the therapeutic response of metronidazole on set of quick response.
