BACKGROUND/AIMS The etiopathogenesis of inflammatory bowel disease (IBD) is multifactorial and not well explained. Environmental, genetic, and dietary factors play an important role. The aim of the study was the evaluation of lactase, saccharase, and maltase activity in patients with IBD. MATERIALS AND METHODS The study comprised 65 children, aged 3-18 years. During a routine endoscopy, we to...

Using synchrotron radiation (SR), the crystal structures of T6 bovine insulin complexed with Ni(2+) and Cu(2+) were solved to 1.50 and 1.45 Å resolution, respectively. The level of detail around the metal centres in these structures was highly limited, and the coordination of water in Cu site II of the copper insulin derivative was deteriorated as a consequence of radiation damage. To provide m...

VOLDŘICH M., SKÁLOVÁ P., KVASNIČKA F., CUHRA P., KUBÍK M., PYŠ P. (2002): Authenticity of 100% orange juice in the Czech market in 1996–2001. Czech J. Food Sci., 20: 83–88. Commercial orange juices samples obtained from the Czech market were analysed in the years 1996–2001. The quality and authenticity of samples was evaluated according to the Code of Practice of AIJN (selected main analytical ...

liposomes as a drug carrier have numerous dominancy. liophilization is the most propr form of these products for long-term maintenance, but this procedure is affected by unstabilizing agent that results in destruction of membrane, release of content and change in size and microbial contamination hence for prevention of the adverse effects, the protective role of sugars such as: maltose, fructos...

we prepared a highly purified and relatively heat stable form of factor viii which contained 25 units per ml (u/ml) activity using peg-4000 and developed an effective and new manufacturing process. heat treatment was performed at 80°c for 72 hrs in the presence of different stabilizers. in our studies, we used different organic solvents as preservatives to maintain factor viii activity, since f...

BACKGROUND The aim of our study was to examine maternal weight gain as well as nutrient intake in pregnancy throughout each trimester compared to current recommendations in a low-risk population and its correlation to birth weight. Additionally, we have investigated the association of maternal nutrition with gestational weight gain and birth weight in an economically unrestricted population. ...

The adaptation of enteric bacteria in seawater has previously been described in terms of nutrient starvation. In the present paper, we bring experimental arguments suggesting that survival of these microorganisms could also depend on their ability to overcome the effects of osmotic stress. We analyzed the influence of osmoregulatory mechanisms (potassium transport, transport and accumulation of...

Surface EMG activities in the masseter muscle were recorded from 8 healthy men with normal permanent dentition during habitual chewing of a small cube of synthetic cellulose sponge which had absorbed distilled water. Three parameters of chewing rhythm, viz., cycle time, duration, and interval, were shown as the respective averages of 40 measurements of the EMG traces of a masticatory series of ...
