background: the basis of spermatogenesis is the spermatogonial stem cells (sscs). the concentration of sscs is very small. however, a system that supports the proliferation and maintenance of sscs in vitro could be used to preserve and expand sscs numbers as well as increase success in transplantation. it is a new avenue to restore spermatogenesis in azoospermia subjects. objective: proliferati...

In this paper, we present some inequalities for the Co-PI index involving the some topological indices, the number of vertices and edges, and the maximum degree. After that, we give a result for trees. In addition, we give some inequalities for the largest eigenvalue of the Co-PI matrix of G.

using fe(no3)3.9h2o, co(no3)2.6h2o and mn(no3)2.4h2o the magnetic properties of nanoparticles trimetalic iron - cobalt - manganese, with supported magnesium oxide have been prepared by co-precipitation and solvothermal methods. the prepared samples are characterized by scanning electron microscope (sem), x-ray diffraction (xrd), vibrating sample magnetometer (vsm) and brunaer-emmett-teller (bet...

conclusions advocacy and publicity to raise awareness of the potential public health impact of hsv and hiv co-infection in nigeria, where anti-hsv testing is not generally performed in all populations, is therefore recommended. background herpes simplex virus 1 (hsv-1) is normally associated with orofacial (orolabial) infections and encephalitis, whereas hsv-2 usually causes genital infections ...

conclusions patients with hiv/aids are more likely to acquire other stis, because the same behaviors that increase the risk of becoming hiv infected can also increase the risk of acquiring stis. having a sore on the skin due to an sti can make the transmission of hiv to the sex partner more likely than people who don’t have such sore in their genital area. results among the 41 patients with hiv...

lu3+/yb3+ and lu3+/er3+ co-doped sb2se3 nanomaterials were synthesized by a co-reduction method in hydrothermal condition. powder xrd patterns indicate that the lnxln′xsb2-2xse3 ln: lu3+/yb3+ and lu3+/er3+ crystals (x= 0.00-0.04) are isostructural with sb2se3. the cell parameters were increased for compounds upon increasing the dopant content (x). sem and tem images show that co-doping of lu3+/...
