Introduction & Objective: Male fertility depends on the proper function of a complex system of organs. Harmful effects of morphine on male reproduction and fertility are well documented. Dopamine facilitates sexual behavior in different animal species. The antagonizing of dopamine D2 receptors with sulpiride was aimed to investigate the interaction of dopaminergic system with morphine-induced i...

Abstract. The cyclic mechanism is one of the basic automatic machines components. It mechanisms that define performance and reliability limits these machines. methods for assessing are based on data dynamic forces acting mechanism's links, leading to their deformation possible destruction under certain operating conditions. Simulation modeling processes in its representation form interconnected...

statement of problem: papillon lefevre syndrome (pls) is a rate autosomal recessive disorder, which is characterized by palmar- plantar hyperkeratosis and rapid periodontal destruction of primary and permanent dentitions. purpose: the aim of the present study was to evaluate the peripheral blood neutrophil function including random locomotion, chemotaxis and oxidative mechanism of killing in a ...

Rat liver microsomal membranes contain a reduced-glutathione-dependent protein(s) that inhibits lipid peroxidation in the ascorbate/iron microsomal lipid peroxidation system. It appears to exert its protective effect by scavenging free radicals. The present work was carried out to assess the effect of this reduced-glutathione-dependent mechanism on carbon tetrachloride-induced microsomal injury...

In order to gain added insight into the mechanisms of allograft destruction, skin grafts were returned to their original donors after remaining as allografts long enough to induce immunity in the intermediate host but not long enough to cause destruction of the graft. Upon their return to unmodified donors, such grafts became revascularized and remained viable. An intense cellular infiltration ...

kinematic synthesis of a trailing six-member mechanism has been carried out to achieve five precision points of an automotive steering mechanism. the inner wheel can be rotated up to forty five degrees with fair accuracy. results show that the divergent end behavior of ackermann steering mechanism has been overcome by the present mechanism. the work is similar to earlier work by the present aut...

Guanethidine, a guanidinium adrenergic neuron blocking agent, when administered chronically at high doses to newborn or adult rats, causes destruction of peripheral sympathetic neurons. Neuronal destruction is preceded by small cell infiltration of the sympathetic ganglia and is suggestive of an immunologically mediated mechanism. Immune reconstitution experiments were carried out to demonstrat...

Cherubism is an autosomal-dominant syndrome characterized by inflammatory destructive bony lesions resulting in symmetrical deformities of the facial bones. Cherubism is caused by mutations in Sh3bp2, the gene that encodes the adaptor protein 3BP2. Most identified mutations in 3BP2 lie within the peptide sequence RSPPDG. A mouse model of cherubism develops hyperactive bone-remodeling osteoclast...

Azo dyes are produced in very large quantities and used as reactive dyes by the cotton industry. They are very stable and resistant to chemical processes. Therefore, their removal from industrial effluents by conventional methods (mechanical screening, sedimentation, biological treatment, biofilters) alone is usually not very effective. This problem can be solved by combining the conventional t...
