introduction: infertility is a common phenomenon in modern societies. today, use of assisted reproductive technologies (arts) for treatment of infertility is common, and cryopreservation is one of these technologies. cryopreservation has impact on the function and percentage of fertility of human sperm. in this study, motility, viability, nitric oxide, and dna apoptosis were assessed before and...

this research aimed to investigate the viability of probiotic bacteria ( lactobacillus acidophilus la-5 and bifidobacterium lactis bb-12) and yogurt bacteria ( streptococcus thermophilus and lactobacillus delbrueckii ssp. bulgaricus ) in yogurt during the fermentation, immediately after fermentation and during refrigerated storage (21 d, 4˚c). also the biochemical characteristics of milk as aff...

The difference between the disease rates of two groups, one exposed and one not exposed to a suspected aetiological factor, is a useful measure of the risk associated with the factor. This measure is of most interest when the association is considered causal, and has been termed the attributable risk (MacMahon and Pugh, 1970). Expressed as a percentage of the total disease rate in a group (the ...

Understanding the reproductive biology is of great importance in development novel hybrids ornamental plants. Pollen fitness-related traits are crucial for pollination success any plant species including dendrobiums. The aim study was to determine and compare fitness ten commercial Dendrobium two indigenous species, D. crumenatum anosmum found Sri Lanka. We measured pollen viability, germinabil...

The input omission trial composed 16 treatment combinations phosphorus (75 kg/ha), potas...

background and objective: the current study was undertaken to check in vitro different characteristics of lactobacillus plantarum as potential probiotic. these characteristics include viability of probiotic and ph during cold storage, tolerance to acid and bile, and antibiotic resistance. material and methods: samples of yogurt were stored at 4°c and analyzed in time 0, 1, 3, 7, 10 and 14 days ...

the germination power of orchids (orchidaceae family) seems to betoo weak due lack of albumen. the study carried out with various treatments including pollination time and ga3 for breaking dormancy and increasing seed germination of orchids. the effect of pollination time (8 periods from january to august) and gibberellic acid (0, 500, 1000 and 1500 mg l-1) were studied on germination of phalae...
