The X-chromosome short tandem repeat (STR) loci are of particular interest for solving complex kinship and paternity cases. Here, we report the genetic data from 209 unrelated Bangladeshi individuals (102 males and 107 females) that were genotyped using the 12 X-chromosomal STR markers included in the Investigator® Argus X-12 kit (Qiagen). The 12 X-STR markers are located in four linkage groups (linkage group I: DXS10135, DXS10148, and DXS8378; linkage group II: DXS7132, DXS10079, and DXS10074; linkage group III: DXS10103, HPRTB, and DXS10101; and linkage group IV: DXS10146, DXS10134, and DXS7423). Allelic frequencies of the 12 X-STR loci and haplotype frequencies of the four linkage groups were investigated. No significant difference was observed in the allele frequencies of males and females. Distributions of heterozygosity were observed from 64.5 to 92.5% among the studied 12 X STR loci. DXS10135 and DXS10101 loci were found to be most polymorphic. For all the four linkage groups, the haplotype diversity was found to be greater than 0.986. A total of 95, 73, 66, and 74 haplotypes were observed in linkage groups I, II, III, and IV, respectively. Hardy-Weinberg equilibrium tests showed no significant deviation from expected values for all 12 loci (p > 0.05). The exact test for pairwise linkage disequilibrium for the 12 loci in the male samples did not show any significant linkage disequilibrium except the DXS10103 and DXS10101 loci after the p values were corrected by Bonferroni's correction for multiple testing (p > 0.05/66). A combined power of discrimination in male and female individuals were 0.999999998159791 and 0.999999999999993, respectively. The combined mean exclusion chance were 0.999997635 in deficiency cases, 0.999999996 in normal trio cases, and 0.999999178 in duo cases. The currently investigated Bangladeshi population showed significant differences when compared with previously reported X-STR data from other 12 populations. The results of the data analysis indicated that all the loci in the Investigator® Argus X 12 kit were fairly informative and might be useful in forensic application and kinship analysis in Bangladeshi population.

Background : The objective of the present study was to evaluate the sub-acute toxic effects of ethanol extract of fenugreek seeds on kidney tissues of albino rats. Materials and methods: The present study was conducted on 30 albino rats divided into Group A, B, C, D and R. Group A (Control group) was treated with distilled water. Group B, Group C and Group D were treated orally with ethanol extract of fenugreek seeds at a dose of 1.25 gm/kg/day, 2.5 gm/kg/day and 5 gm/kg/day respectively for 90 consecutive days. Group R (Recovery group) was treated with seed extract of 5 gm/kg/day for 90 days followed by no treatment for next 28 days to observe any toxic effect if present in highest dose whether reversible or not. On 91st day all the animals of Group A, Group B, Group C and Group D were sacrificed and Group R was sacrificed on 119th day. Blood sample was collected from all the rats by cardiac puncture before sacrifice for measurement of biochemical and hematological parameters, and kidneys were collected for histopathological examination after sacrifice. Results: Upto 2.5 gm /kg/day dose level, all parameters of all experimental groups were statistically not significant when compared with control group. At 5 gm/kg/ day dose level the seeds extract produced statistically significant change in biochemical parameters such as serum creatinine and blood urea. In gross microscopic examination of kidney, at the highest dose level showed the sign of cell injury like cellular swelling, hemorrhage, inflammatory cells infiltration, necrosis etc. Interestingly, these biochemical and microscopic findings at the highest dose level were absent in recovery group. Conclusion: Finally, the study revealed that ethanol extract of fenugreek seeds was non toxic up to 2.5 gm/kg/day dose level and produce renal toxicity at 5 gm/kg/day dose level in sub acute toxicity test. So, if needed to use in higher therapeutic dose the toxicity profile of seeds extract must be re-evaluated. Chatt Maa Shi Hosp Med Coll J; Vol.18 (1); Jan 2019; Page 36-43

Haplotype diversity and allele frequencies of 23 Y chromosomal short tandem repeat (STR) loci included in the next-generation PowerPlex® Y23 System were studied in 137 Bangladeshi Bengali males. A total of 134 different haplotypes were observed with a discrimination capacity (DC) of 0.978, indicating a high potential for differentiating between male individuals in this population. The highest allele frequency (0.818) was observed in locus DYS391. Locus DYS385a/b showed the highest gene diversity (0.945) while locus DYS391 showed the lowest gene diversity (0.302). Double alleles were detected in three loci. On the other hand, four null alleles were detected in a single haplotype at DYS448, DYS549, DYS392, and DYS385a/b locus, respectively. The haplotype data is available in the Y chromosome haplotype reference database under accession number YA003445. To understand the genetic diversity of Bangladeshi Bengali population, a pairwise genetic distances (Rst) was calculated by comparing with 23 population studies consisting 4249 haplotypes. The analysis placed the Bangladeshi population along with Indian Tamil and Indo-Pakistani population in a clade separated from the rest.
