OBJECTIVES A period of thrombocytopenia is common after stem cell transplantation (SCT). To prevent serious bleeding complications, prophylactic platelet transfusions are administered. Previous studies have shown that a rise in immature platelets precedes recovery of platelet count. Our aim was to define a cutoff value for immature platelets predicting thrombopoietic recovery within 2 d. METH...

Biomass of microalgae and the components contained in their cells can be used for production heat, electricity, biofuels. The aim presented study was to determine optimal conditions that will most favorable large amounts biomass intended energy purposes. analyzed effect type lighting, time lighting culture, pH culture medium on growth Chlorella vulgaris biomass. experiment carried out vertical ...

background: the aim of the present study was the comparison of humoral and cell-mediated immunity in broilers fed with different levels of zinc during a coccidiosis challenge. methods: one hundred and forty- four one-day-old broiler chicks were used with three dietary zinc (40, 120 and 200 mg/kg). at 14 d of age, all birds were inoculated orally with 5×10 3 sporulated oocysts of e. tenella . at...

Background and aims: Trichomoniasis is the most common non-viral sexually transmitted infection worldwide; although it treated by a 5-nitroimidazole drug family such as metronidazole (MTZ) with numerous side effects, in this regard, alternative new drugs are required. Therefore, study examined anti-Trichomoniasis effect of hydroalcoholic extract some traditional medicinal plants Iran vitro. Met...

The objectives of this study were to investigate the effect of laser-induced surface features on the morphology, attachment and viability of mesenchymal stem cells (MSCs) at different periods of time, and to evaluate the biocompatibility of different zones: laser-melted zone (MZ), heat-affected zone (HAZ) and base metal (BM) in laser-treated NiTi alloy. The surface morphology and composition we...

Morphological microscopic examinations of nucleated cells in body fluid (BF) samples are performed to screen malignancy. However, the morphological differentiation is time-consuming and labor-intensive. This study aimed to develop a new flowcytometry-based gating analysis mode "XN-BF gating algorithm" to detect malignant cells using an automated hematology analyzer, Sysmex XN-1000. XN-BF mode w...

Background Two of the key parameters to be monitored during cell cultivation processes are cell concentration and viability. Until today, this is very often done off-line by sterile sampling and subsequent counting using a hemocytometer or an electronic cell counter. Cell biology lacks a measurable quantity by which single cells in suspension can be non-invasively diagnosed as dead or alive. Ho...

BACKGROUND Glutamine is routinely added to most cell cultures. Glutamine has been found to be the preferential nutrient to the rapidly replicating intestinal mucosa, but whether this is a metabolic effect or due to other properties of this amino acid is not determined. To study the importance of glutamine on the growth of two enterocyte-like cell lines, the effects of depriving the media or sup...

The giardiacidal efficacy of simple disinfecting materials, ie lemon juice, vinifer, and vinegar, for uncooked foods with Giardia cysts was investigated to help travelers in Giardia-endemic areas. The cysts were obtained from stools of individuals with Giardia intestinalis infection by modified sucrose gradient procedure. A pooled batch of 3 x 10(4)/ml Giardia cysts was made from all specimens....

Five treatments including Conway medium, media containing 0.1, 0.17, 0.3 and 0.5 mg l-1 ferrous (Fe; in the first experiment), media with 1, 1.26, 1.59, 2 mg l-1 concentrations of phosphorous (P; in the second experiment) and a pure sample of Tetraselmis suecica were cultured under laboratory conditions. Growth rate of the algae was determined using the optical density method at 750 nm and numb...
