The cytotoxicity of the biomaterials is a key issue that should be addressed prior to pre-clinical applications. This study was designed to evaluate and compare the cytotoxixity of two forms of bioactive glasses:nanopowder and micropowder. Human HGF1-PI53 gingival fibroblast cells were used to evaluate the cytotoxicity of 0.5, 1, 1.5, 2, 5, 10, 15 and 20 mg/ mL concentrations of the two bioacti...
In the 2013 case Isaacson v. Horne, the US Court of Appeals in the Ninth Circuit ruled that Arizona House Bill (HB) 2036, which prohibited abortions after twenty weeks of gestation [3], was unconstitutional. The Arizona State Legislature passed the law in 2012, which was then challenged by three physicians who filed a lawsuit against the state, arguing that the law violated women's constitution...
BACKGROUND Consumption of caffeine and alcohol is suspected to affect pregnancy outcome. Use of both stimulants is widespread and even minor effects on fetal viability are of public health interest. METHODS We performed a nested case-control study using prospective data from a population-based cohort comprising 11088 women aged 20-29 years. From this cohort, women who experienced either a spo...
Genetically determined polymorphisms incorporating multiple traits can persist in nature under chronic, fluctuating, and sometimes conflicting selection pressures. Balancing selection among morphs preserves equilibrium frequencies, while correlational selection maintains favorable trait combinations within each morph. Under negative frequency-dependent selection, females should mate (often disa...
objective: the aim of this study was to estimate the cheminformatics and qualitative structure-activity relationship (qsar) of cinnamaldehyde and eugenol. the effects of cinnamaldehyde and eugenol on the viability, doubling time and adipogenic or osteogenic differentiations of human adipose-derived mesenchymal stem cells (hascs) were also investigated. materials and methods: qsar and toxicity ...
the ability of whey protein concentrate (wpc) (1% w/v) and/or honey (2% and 4% w⁄v) to improve lactic acid bacteria (streptococcus thermophilus and lactobacillus delbrueckii subsp. bulgaricus) growth and viability in yoghurt during a 21 day period of storage was investigated. another focus of this study was to examine fermentation kinetics and post-acidification rates through ph and lactic acid...
streptococcus iniae is one of the most important agents that causes high mortality and losses in rainbow trout farms in iran and the world. these bacteria can affects the consumers and people who deal with aquaculture via affected fish. so, viability of this bacterium in frozen fish and fish product can be useful for health care of consumers. a total of 90 rainbow trout, with average weight of ...
background: spermatozoa cryopreservation is used for the management of infertility and some other medical conditions. the routinely applied cryopreservation technique depends on permeating cryoprotectants, whose toxic effects have raised the attention towards permeating cryoprotectants-free vitrification technique. objective: to compare between the application of slow cryopreservation and vitri...
background: human sperm cryopreservation has proven to be very valuable. cryopreservation has effects on function, morphology and percentage of fertilization capacity of human sperm. also, it has been revealed that cryopreservation has a role in sperm dna fragmentation and infertility. in this study, viability, motility, dna fragmentation and for the first time, intracellular nitric oxide asses...
