ABSTRACT
To examine the role of calpain-10 SNP-44, -43, -63 and del/ins-19 in genetic susceptibility to type 2 diabetes mellitus [T2DM] and associations with triglycerides and total cholesterol in a group of subjects residing in the Gaza Strip. Ninety-six individuals were examined: 48 T2DM patients and 48 controls. The groups were genotyped for calpain-10 SNP-44, -43, -63, and del/ins-19. Mutagenically separated polymerase chain reaction was used to examine SNP-44; del/ins-19 was examined by electrophoresis of the PCR product on agarose gel, while the restriction fragment length polymorphism method was used for SNP-43 and -63. There was evidence that the C allele at SNP-44 played a possible role in susceptibility to T2DM [p = 0.01]. T2DM patients with G/A genotype were found to have higher levels of total cholesterol in comparison to those homozygous for allele 1 [G/G] in SNP-43. Total cholesterol levels increased in T2DM patients who are homozygous for del/ins-19 allele 2, in T2DM patients with the 121/221 haplotype combination, and in control subjects with the haplotype combination 111/121. SNP-44 polymorphism of the calpain-10 gene has a significant association with T2DM patients in the Gaza strip. Certain polymorphisms of calpain-10 also have associations with the levels of total cholesterol in both T2DM patients and controls
ABSTRACT
Most physicians in Gaza prescribe medicaments for patient's suffering from Entamoeba histolytica/dispar without parasitologic diagnosis. Additionally, stool analysis performed by the routine methods usually reports the species as E. histolytica without confirmation. In this study, 92 stool specimens were collected and analyzed by wet mount, iron haematoxylin staining, antigen detection of E. histolytica and polymerase chain reaction [PCR]. The total number of E. histolytica identified by PCR was 64 that of E. dispar was 21. Mixed infection with both E. histolytica and E. dispar was evident in 7 specimens. In the light of these results, approximately 30% of suspected clinical amoebiasis cases were negative for E. histolytica. It is recommended to use PCR for diagnosis of stool specimens from patients with E. histolytica/dispar and that treatment should be prescribed for only patients positive for E. histolytica
