The computation of optical ow from image derivatives is biased in regions of non uniform gradient distributions. A least-squares or total least squares approach to computing optic ow from image derivatives even in regions of consistent ow can lead to a systematic bias dependent upon the direction of the optic ow, the distribution of the gradient directions, and the distribution of the image noi...
tyrosinase is a multifunctional copper-containing enzyme. it can catalyze two distinct reactions of melanin synthesis and benzaldehyde derivatives, which are potential tyrosinase inhibitors. to find the relationships between charge distributions of benzaldehyde and their pharmaceutical behavior, the present study aimed at investigating nuclear quadrupole coupling constants of quadrupolare nucl...
in the recent years, the role of lox enzymes in the cause of neoplastic diseases such as colorectal, skin, pancreatic and renal cancers has been confirmed. a new series of 1,3,4-thiadiazole derivatives bearing 2-pyridyl moiety was synthesized and their cytotoxicity was assessed using mtt protocol. enzyme inhibitory activity of prepared compounds was also tested against 15-lipoxygenase-1 as nove...
Guanidine and its derivatives have wide applications in various industries and energetic materials. Because of these wide applications, various researches are concentrated on the synthesis of guanidine and its derivatives. This review article has introduced synthesis methods of guanidine and its derivatives. Guanidine synthesis routes like addition of ammonium salts to cyanoguanidine or cyanam...
in this work, different ethyl 2,4-dioxo-4-arylbutanoate derivatives were prepared and evaluated for their src kinase inhibitory activity. for this purpose, the appropriate substituted acetophenone derivatives reacted with diethyl oxalate in the presence of sodium ethoxide in dried ethanol to give the corresponding products. all compounds showed moderate activities comparing with staurosporine a...
In the present research, two sets of data were analyzed for the purpose of obtaining the oscillatory derivatives of the sway force and yaw moment with respect to the sway velocity and sway acceleration. The results of the analysis show that the values of the derivatives which were calculated from the dynamic test data are somewhat different from the values of the same derivatives which were cal...
Quinones such as 1,4-naphthoquinones are abundant in nature and naphthoquinone based natural products are known to possess anticancer activity. This pharmacophore is known to convey anticancer activity to some drugs such as streptonigrin, mitomycin A, etc. We synthesized and characterized different classes of naphthoquinone derivatives including bis naphthoquinone, 2-arylaminonaphthoquinone, be...
The quadrants' boundary intensity discontinuity a result of of the video-camera consisting of four separate A/D banks. As a result, ow estimation at the quadrant boundaries is inaccurate. The problem could be overcome by local gain compensation. The dense ow algorithms of Black and Anandan 6] is used. The algorithm's parameters were changed to achieve best measurement results. The same eeect co...
BACKGROUND Hydroxyethyl starches (HES) accumulate in the circulation when administered repeatedly. Accumulation is thought to be partly responsible for undesirable effects (tissue storage, blood coagulation impairment, and itching). HES 130/0.42 with low molecular weight and a low level of substitution has recently been developed in order to reduce those risks. METHODS In healthy volunteers, ...
Introduction Previous research has indicated that fluid choice is an important component of the resuscitation of the critically-ill patient. Synthetic hydroxyethyl starches (HES) may remain within the intravascular space compared to crystalloid solutions, yet they have also been associated with acute kidney injury. Data comparing HES and crystalloid solutions in anesthesia is incomplete. The go...
