A total of 181 faecal samples were collected from wild cervids in two regions of Poland. Giardia cysts were detected in one faecal specimen from red deer and in two samples from roe deer. Fragments of the beta-giardin (bg) triose phosphate isomerase (tpi) and glutamate dehydrogenase (gdh) genes were successfully amplified from the Giardia isolate obtained from red deer, whereas only amplicons o...

The chlorophyte microalga Chlorella sorokiniana was tested for the bioremediation of heavy metals pollution. It cultured with different concentrations Cu2+, Cd2+, As (III) and (V), showing a significant inhibition on its growth at 500 µM 250 750 AsO33- 5 mM AsO43- or higher. Moreover, consumption ammonium also studied, differences higher than 1 Cu2+ (III), (V). determination intracellular conce...

GDH has been known to be related with hyperinsulinismhyperammonemia syndrome. We have screened new drugs with a view to developing effective drugs modulating GDH activity. In the present work, we investigated the effects of a new drug, KHG26377 on glutamate formation and GDH activity in cultured rat islets. When KHG26377 was added to the culture medium for 24 h prior to kinetic analysis, the V(...

background: this study was conducted to determine of molecular epidemiology of the giardia lamblia by pcr-rflp method in tehran, capital of iran. methods: thirty eight stool samples were randomly selected from 125 patients diagnosed with giardiasis using microscopy in tehran. dna extraction of some samples were performed by phenol/chloroform/isoamyl alcohol method and to raise the sen­sitivity ...

Background and Aims: Diabetes is one of the most important endocrine disrupters and is associated with various hormones, including those that can lead to diabetes. Glucocorticoid use may lead to insulin resistance. Dexamethasone is one of these glucocorticoid compounds. Glutamate dehydrogenase plays a key role in the production of glutamate in the secretion of insulin. Based on these hormonal i...

Background and aims: We investigated the children of Parana State, Brazil the prevalence of intestinal parasitosis and the associated factors involved in the transmission of intestinal parasites, and we genotyped the Giardia duodenalis isolates obtained. Methods: Fecal samples were analyzed by established microscopic methods. G. duoden...

Clostridium difficile is the most common infectious cause of nosocomial diarrhea, affecting thousands of patients annually and exacting enormous costs on the U.S. health care system. Early diagnosis is critical to prevent transmission and reduce morbidity and mortality, yet sensitive and specific diagnostic tests with a quick turnaround time are lacking. The objective of this study was to deter...

To evaluate the geographic distribution of Giardia intestinalis genotypes in Nablus, West Bank, Palestine, a genotyping study was performed using clinical fecal samples. Microscopic examination confirmed that 8 of 69 (11.6%) samples were G. intestinalis positive, and subsequent genotyping analyses targeting the small-subunit ribosomal RNA (18S rRNA) and glutamate dehydrogenase (GDH) genes revea...

PURPOSE This study aimed to investigate the expression of glutamine metabolism-related protein in tumor and stromal compartments among the histologic subtypes of thyroid cancer. RESULTS GLS1 and GDH expression in tumor and stromal compartments were the highest in AC than in other subtypes. Tumoral ASCT2 expression was higher in MC but lower in FC (p < 0.001). In PTC, tumoral GLS1 and tumoral ...

Tellurite is toxic to most microorganisms because of its ability to generate oxidative stress. However, the way in which tellurite interferes with cellular processes is not fully understood to date. In this line, it was previously shown that tellurite-exposed cells displayed reduced activity of the α-ketoglutarate dehydrogenase complex (α-KGDH), which resulted in α-ketoglutarate (α-KG) accumula...
