(fabaceae) consists of perennial herbs grow in sandy soils with hard lightness. three species of the genus grow in iran, among them g. glabra l. has the widest distribution. it is well known in english as licorice and the root extract includes flavonoids and glycyrrhizin are used widely in medicine, food industry, tobacco products and other industries. liqui...

we describe a 16 year old boy with acne fulminans associated with axial and peripheral polyarthritis. the patient's clinical course and therapy with isotretinoin, prednisolone and oxytetracycline are described. a possible association between the presence of hla -b 27 antigen and reactive arthritis with acne fulminans in this case is evaluated. a review of the literature is included.

sperm is particularly susceptible to reactive oxygen species (ros) during critical phases of spermiogenesis. however, the level of seminal ros is restricted by seminal antioxidants which have beneficial effects on sperm parameters and developmental potentials. mitochondria and sperm plasma membrane are two major sites of ros generation in sperm cells. besides, leukocytes including polymer phonu...

Polymer nanocomposites are being used more widely in a variety of industries. As the compatibilizer, Elvaloy-AC-3427 (EAC) was addition to Cloisite 30B (C3B) as reinforcement filler this research. For production Polyethylene/Cloisite 30B/Elvaloy AC-3427 nanomaterials, twin-screw extruder is employed. added Polyethylene matrix range 2%, 3%, 4%, and 5%. The mechanical thermal characteristics comp...

The objective of this work is to study the effect addition compatibilizing agent poly(ethylene-alt-maleic anhydride) (HDPE-alt-MAH) on mechanical properties and morphology HDPE/PA12 blends. amounts compatibilizer used were 0, 2, 3 wt% blends manufactured in three ratios, namely: 75/25, 50/50, 25/75. It was observed that with 2 HDPE-alt-MAH presented best performance. As proportion PA12 blend in...
