background: ca-125 is a glycoprotein and its origin is uncertain during pregnancy. it arises during the first trimester and return to a non-pregnancy range in late pregnancy. objective: the aim of this study was to compare ca-125 level in threatened abortion and normal pregnancy less than 20 weeks of pregnancy. materials and methods: this was a prospective case study carried out on 50 healthy p...

Reaction of tryptamine 1 with dimethyl -3-methoxyallylidenemalonate 2 afforded N?-[4,4-bis (methoxycarbonyl)-1,3-butadienyl] tryptamine 3 which in combination with acetylchloride and pyridine in dichloromethane gave N?, N?-[acetyl]-[(4,4-dinethoxycarbonyl) 1,3butadienyl] tryptamine 4. Treatment of 3 with sodium hydroxide afforded 2H[N-(3-indolyl) ethyl] 2-oxo-3-methoxycarbonyl-1-pyridine 5. Cy...

background and objectives : pseudomonas aeruginosa is one of the most important gram negative opportunistic bacteria which causes infection among burn patients. resistance to the antibiotics in this group of bacteria is increased due to the activity of extended spectrum β-lactamase (esbls) genes. in the current study, we investigated the prevalence of two genes (blaper-1 & blaoxa10) related β-l...

‎Bucket recursive trees are an interesting and natural‎ ‎generalization of ordinary recursive trees and have a connection‎ to mathematical chemistry‎. ‎In this paper‎, ‎we give the lower and upper bounds for the moment generating‎ ‎function and moments of the multiplicative Zagreb indices in a‎ ‎randomly chosen bucket recursive tree of size $n$ with maximal bucket size $bgeq1$‎. Also, ‎we consi...

background: caprine besnoitiosis is an economically important disease of goats. neospora caninum, another coccidian parasite of worldwide distribution, infects several animal species and is a major cause of abortion in cattle . combined infections of n. caninum and besnoitia caprae can occur in geo-graphical areas endemic for both species of parasite in goats. this experiment was conducted to i...
