Blastocystis is an emerging protistan parasite colonizing the human intestine. It is frequently reported to cause general intestinal symptoms of vomiting, diarrhea, and abdominal pain. We recently demonstrated that Blastocystis rearranged cytoskeletal proteins and induced intestinal epithelial barrier compromise. The effect of Blastocystis on enterocyte apoptosis is unknown, and a possible link...
23 24 Blastocystis is a ubiquitous enteric protozoan found in the intestinal tract of humans and a 25 wide range of animals. Accumulating evidence over the last decade suggests association 26 of Blastocystis with gastrointestinal disorders involving diarrhea, abdominal pain, 27 constipation, nausea and fatigue. Clinical and experimental studies have associated 28 Blastocystis with intestinal in...
Variable-energy positron annihilation depth-profiling has been applied to the study of the Si/SiOz interface in Al-gate metal-oxide-semiconductor (MOS) structures. For both nand ptype silicon under conditions of negative gate bias, the positron annihilation S-factor characteristic of the interface (Sint) is substantially modified. Temperature and annealing behavior, combined with known MOS phys...
Two tribal groups from southern India--the Chenchus and Koyas--were analyzed for variation in mitochondrial DNA (mtDNA), the Y chromosome, and one autosomal locus and were compared with six caste groups from different parts of India, as well as with western and central Asians. In mtDNA phylogenetic analyses, the Chenchus and Koyas coalesce at Indian-specific branches of haplogroups M and N that...
There is limited data on the role of intestinal parasites in irritable bowel syndrome (IBS) in South America. We evaluated the association between intestinal parasitism and IBS status in Peru. Intestinal parasites were detected in 43% of the IBS cases and in 51% of the controls (P = 0.4). After excluding those infected by any parasite, the IBS prevalence remained high (22%; P = 0.7). No statist...
Two hundred diarrhoea specimens collected during January to February 1988, from rural children aged 0 to 60 months in Kakamega District were examined for bacteria, parasites and rotavirus. The results were compared with a sample of 184 diarrhoea specimens matched for month of collection, taken from data collected in the same manner from children in Kiambu District. The mean ages of children in ...
100 random fecal samples sent to the clinical laboratory of the Aga Khan University Hospital were used. Microscopy was done by direct wet mount in which approximately 2 mg of feces (the amount that usually adheres to one end of the wooden applicator stick) was thoroughly emulsified on a glass slide in one dropofphysiologic salineandcovered with acoverslip. A similar preparation was made on anot...
ABSTRACT: THe prevalence of intestinal parasites in stool specimens studied during (1990 - 1995) were assessed by formalin -ether concentration technique and light microscopy. 3 Specimens from each of 23123 patients were examined .Patients were detected in 45.7% of all stool samples. Releative frequeies of different parasites were:Ascaris lumbricoides (3.4%), Trichuris trichiura (0.9%),Hymeno...
