medicine had never been error free. medical society has responsibility to reduce the rate of medical errors and should respect to people and patients rights in the case of error occurrence to maintain their trust. waiver of cause of medical errors, what is of importance is recognizing the ethical duty of physician toward her patient in the case of error commitment. in this paper at the first, t...

The effects of alkalinity on alkaline hydrothermal conversion (alkaline-HTC) of cellulose to bio-oil were investigated in this study. The results showed that the initial alkalinity greatly influenced the reaction pathways. Under initial strong alkaline conditions with final pH greater than 7, alkaline-HTC only followed the alkaline pathway. However, under initial weak alkaline conditions with f...

background: there are some controversial data on application of progesterone and progesterone plus estrogen at luteal phase. objective: to investigate the effects of different luteal support hormones on the alkaline phosphates (alp) activity in the endometrial epithelium and endometrial thickness during superovulation process for obtaining the optimized endometrial receptivity in animal model. ...

background: collagen, the most abundant protein in the human body, and as an extracellular matrix protein, has an important role in the fiber formation. this feature of the collagen renders  establishment of the structural skeleton in tissues. regarding specific features associated with the collagen, such as, formation of the porous structure, permeability and hydrophilicity, it can also be use...

conclusions ehp was able to both reduce ldl-ch and to significantly decrease markers of oxidative stress and lipid peroxidation induced by hyperlipidemia. therefore, this herb, as a new pharmacological component, could be used to reduce certain blood lipids, lipid peroxidation, and aminotransferase markers. materials and methods thirty-two male rats weighting 200 ± 10 g were randomly divided in...

matococcus daniellii Benth.i) The moleculaT mass of the protein is 22 kDa and the higher order structure of the protein is maintained by eight disulfide bridges.2・3) Thaumatin is the sweetest substance for man and is, on a molar basis, 100,OOO times sweeter than sucrose.i) Today, thaumatin is used commercially for its intense sweetness, taste masking, fiavor enhancement, and synergistic propert...

the output error of the globoidal cam mechanism can be considered as a relevant indicator ofmechanism performance, because it determines kinematic and dynamical behavior of mechanicaltransmission. based on the differential geometry and the rigid body transformations, themathematical model of surface geometry of the globoidal cam is established. then we present theanalytical expression of the ou...
