The objective of this study was to determine whether there were doses at which the synthetic progestin, norgestomet, could mimic midluteal phase concentrations of progesterone in regulating the secretion of LH and 17 beta-estradiol in bovine females. Heifers were randomly assigned to one of five groups to receive: 1) one (1Norg, n = 5), 2) two (2Norg, n = 5), 3) four (4Norg, n = 5), or 4) eight...

Methods Plasma and Peripheral blood mononuclear cells (PBMCs) were longitudinally collected in 41 PHI patients (infection <90 days), 24 remained untreated (ART-naive) and 17 were ART-treated one year later. In addition, samples from elite controllers (EC, n=12) and healthy subjects (HS, n=12) were also assessed. IDO enzymatic activity marker (Kyn/Trp ratio) was measured by isotope dilution tand...

objective: to investigate the anti-urolithiatic effect of aqueous extract of leaves of bryophyllum pinnatum (b. pinnatum) on ethylene glycol-induced renal calculi. materials and methods: thirty-six wistar male rats were randomly divided into six equal groups. group a animals received distilled water for 28 days. group b to group f animals received 1% v/v ethylene glycol in distilled water for 2...

The Platelia Candida-specific antigen and antibody assays (Bio-Rad Laboratories) were used to test serial serum samples from seven neutropenic adult patients with hematological malignancies who had developed systemic Candida tropicalis infections. The diagnosis of candidiasis was based on a positive blood culture (all seven patients) and the isolation of C. tropicalis from a normally sterile si...

We studied the changes in blood glucose concentration in blood samples collected in heparinized specimen tubes containing no other preservative, or containing NaF, D-mannose, or a combination of NaF and D-mannose. Blood concentration in samples taken into NaF decreased by 0.40 mmol/L in the first 2 h; thereafter, there was no change. In samples collected into mannose there was a small but signi...

The reliability of MYCO/F Lytic medium in the BACTEC 9240 blood culture system was evaluated by comparing its performance to that of the Isolator system for the recovery of fungi and to that of the ESP II system for the recovery of mycobacteria. Of 717 specimens of blood cultured for fungi, 24 were positive; 12 samples were positive with both systems, 7 samples were positive with the Isolator s...

Effects of selenium on certain indicators of sheep reproductive success and on Se level in the sheep’s blood serum were studied in 2001-2002 on 100 Polish merino sheep ewes kept in a Western Pomeranian sheep farm. The 100 ewes were picked out on random and divided into two equal groups: treatment and control. The blood samples for serum Se assays were collected prior to administration of sodium...

this study investigated the effects of short-term fasting and re-feeding on hematological and immunological parameters of mesopotamichthys sharpeyi (günther, 1874) fingerlings. after 2 weeks of adaptation, 360 fish with an average initial body weight of 6.13±0.40g were distributed in nine 300-l circular fiberglass tanks provided with aeration system following a completely randomized design. the...

The study presents the results of a research on the frequency of infection with Enterobius vermicularis in different urban and rural human populations, conducted by Zoology Department of Podlaska Academy in Siedlce between 1998 and 2006. Since 2001, samples from one examinee were collected seven times. On the basis of the seven tests, a table of the frequency of infection and the efficiency of ...
