Kefir is a fermented milk product comprising several lactic acid bacteria, acetic acid bacteria and yeasts. It has been reported to possess pharmacological and antioxidant activities. Recently, kefir from rice milk showed antioxidant activity higher than that from cow milk. To see whether rice and rice products such as rice kefir is safe for human applications. Therefore, the present study was designed...
The current stage of medical science development leads to the elaboration and implementation of new information technologies. It acquires particular importance in the study of cells - the basis of any biological system. The offered approach to finding information on morphofunctional state of hormone producing cells is based on decomposition of their special activity on 4 components (synthesis, secretion,...
Positron emission tomography (PET) is a tomographic imaging technique that allows for accurate non-invasive in vivo measurements of regional tissue function in man. It is the most selective and sensitive imaging modality able to measure molecular pathways and interactions in vivo at a picomolar level. PET is an important tool in drug development and can be used in different ways. Firstly, it is possible...
Cellulose is the largest renewable resource in the world, and it has the highest utilization value in biomass energy. But the biggest problem in usage of cellulose is degradation, the most effective solution is to make use of cellulase to degradated it, which is thorough and free from contamination. With gradually increased understanding of cellulase, more and more people start to study the cellulase...
In order to observe the anti-aging and life-delay effect of taurine, the drosophila were divided into two parts, one part for the survival experiment, recorded the deaths until all the drosophila died, the mean life span(MLS), half a time of death (LT50) and mean maximum life span(MMLS) of drosophila were noted, the content of SOD and MDA in control and dose groups from both sexes were determined...
Because of the wide existence and serious endocrine disturbing for humans and animals, the steroid estrogen hormones have been focused more and more in recent years. Steroidal estrogen hormones such as 17β-estradiol and estrone are particular concerns because there is evidence that low nanogram per liter concentrations of them in water can adversely affect the reproductive biology of fish and other...
Among a series of dose of Yeast immunity polysaccharide (YSP, 0.2%,0.5% and 1%), the time of the experiment was 21d and the index of immunity was measured at different stages. The result showed that YSP had positive effect on the immunity of Apostichopus japonicus at normal states, which it could hold for some time. Immunity function of most tested groups reached the highest level at the 14th day...
Most new drug candidates generated during in vitro screenings turn out to be invalid after time-consuming and costly testing in animal models. Therefore, development of noninvasive, real-time, sensitive, and cost-effective tools with higher throughput for monitoring and early detection of drug efficacy in vivo is urgently needed. Of such techniques, optical molecular imaging provides many advantages...
Cytosine DNA methylation plays an essential role in regulating gene expression and silencing transposons in various animals, plants and fungi. Recent advances in next-generation DNA sequencing technologies have enabled to observe genome-wide DNA methylation status; especially, bisulfite sequencing allows us to collect DNA methylation status at single-base resolution. However, one of major problems...
In this research, results of an experimental study of prickly ash seed cust oil on the preparation of fatty acid methyl ester by lipase catalysis were presented. Factors such as n-hexane, the FAME rate, water concentration, volume of lipase, et al were studied. The experiment results showed that n-hexane is most suitable solvent in the non-aqueous lipase catalytic system and the FAME rate reach the...
Physiological field of manipulating metabolism tries to elucidate how tissues recuperate after ischemic reperfusion changes, how signal-molecules coordinate metabolic pathways and what physiological changes to expect in induced artificial hypometabolism or suspended animation in biomedicine. Certain animals are adapted to oscillations in photoperiod, food abundance and thermal changes in the environment...
We demonstrate a microfluidic system allowing stable immobilization of young adult C. elegans for neuronal and behavior analysis upon chemical stimulations. Chemical stimuli were delivered to the head of the animal by rapid interface shifting of laminar flows and neuronal activities could then be monitored by in vivo Ca2+ imaging.
In the present study, histopathological changes were recorded in the gill of fresh water bivalve, Parreysia cylindrica after acute exposure to endosulfan alone and in combination with 50mg/l and 100mg/l of L-ascorbic acid. Due to endosulfan intoxication, damage to the gill was extensive resulting in hyperplasia, degeneration, necrosis in secondary gill lamellae and connective tissue, swelling, rupture...
Small animal positron emission tomography (PET) is a potentially powerful tool for understanding the molecular origins of debilitating brain disease such as dementia, depression and schizophrenia. However, its full potential in such investigations has not yet been realized due to the use of anaesthesia to avoid motion artifacts. Anaesthesia alters biochemical pathways within the brain and precludes...
