in the human genome, chromosome 11 contains a cluster of matrix metalloproteinase (mmp) genes. single nucleotide polymorphisms in the promoter region of mmp genes are important for mmp expression. a common adenine deletion polymorphism (5a) at position -1171 of the mmp-3 gene promoter (5´-aaaaaaccat-3´ change to 5´-aaaaaccat-3´) facilitates transcriptional factor binding and mmp-3 promoter acti...

objective(s): 3, 4-methylenedioxymethamphetamine (mdma) one of the methamphetamine derivatives that affect the reproductive system, has not been well understood. many young people are consumers of drugs such as mdma that can affect their reproductive capability. apoptosis is the main mechanism for male infertility. pentoxifylline (ptx) increases camp intracellularly and reduces tumor necrosis f...

a water soluble, bronsted acid, 5-sulfosalicylic acid as an efficient organocatalyst was used for the synthesis of physiologically active 2-substituted benzimidazole derivatives from o-phenylenediamine and aromatic aldehydes in ethanol at reflux condition. cost-effectiveness, use of non-hazardous solvents, metal free and commercially available catalyst, single-step, environmentally friendly gre...

Surveys were carried out to determine species composition and host range of powdery mildews (Erysiphaceae) in Gilan province, Iran. Twenty seven taxa were identified. Among them Erysiphe circaeae, E. punicae, E. urticae, Microsphaera erlangshanensis, M. multappendicis, M. trifolii and Podosphaera clandestine/ var. cydonia are new to Iran. Parietaria officinalis and Phuopsis stylosa are new host...
