results the results showed that children with a higher weight z-score spend more time in sedentary activities and less time running or involved in active games. scd-1 activity index, arachidonic/linoleic index, and adipocyte volume were significantly higher in children with a weight z-score greater than 0. the preadipocyte number and the genetic expression of the studied genes did not differ be...

widespread occurrence of h9n2 low pathogenic avian influenza (lpai) viruses in many asian countriesduring the past decade has resulted in the need for evaluation of the pathogenesis of h9n2 virus infection. in this study, tissue tropism and dissemination of a/chicken/iran/772/1998(h9n2) virus throughout the body of broiler chickens were investigated. the clinical signs, gross lesions and antibo...

this paper presents four cases of abnormal soft tissue activity in the bone scan of patients with different lesions (lung inflammatory pseudotumor, pulmonary fibrosis, pulmonary metastatic osteosarcoma and metastatic hepatic carcinoma of colon).

for evaluation of iranian onion morphotypes potentials and application of them in breedingprogrames, seeds of 23 iranian onion morphotypeswere collected from east azarbaijan (redazarshahrmorphotypes), tehran (red rey morphotypes), razavi khorasan (red neyshaboormorphotypes) and zanjan (gholyghese morphotypes). these onion morphotypes were planted inrcbd design in four replications in seed and p...

aflatoxins (afs) are one of the most important mycotoxins due to their common occurrence in feedstuffs and feeds that pose a serious threat to humans and animals. although many outbreaks of acute and chronic diseases have been attributed to consumption of aflatoxin-contaminated foods, the most significant effect of aflatoxin is hepatotoxicity in farm animals, especially aflatoxicosis in shrimps...

an important part of plant in vitro techniques is the sterilization of explants and the maintenance of aseptic conditions. ideally, sterilizing materials should be effective on a vast range of microorganisms at low density. nowadays, the use of compounds such as essential oils (eos) and nanoparticles is applicable in microbiology studies. the main objective of this experiment was to study the s...

injection of synthetic fillers for soft tissue augmentation is increasing over the last decade. one of the most common materials used is hyaluronic acid (ha) that is safe and temporary filler for soft tissue augmentation. we present a case of 54-year-old female who experienced vascular occlusion and nasal alar necrosis following ha injection to the nasolabial folds. she suffered from pain, necr...

stem cells are self-renewing cells that can be differentiated into other cell types. conventional in vitro models for studying stem cells differentiation are usually preformed in two-dimensional (2d) cultures. the design of three-dimensional (3d) in vitro models which ideally are supposed to mimic the in vivo stem cells microenvironment is potentially useful for inducing stem cell derived tissu...

X-ray measurements were carried out in order to study the spontaneous radiation effects of alianite, gadolinite and monazite on their structures. It was found that the first two gave the experimental evidences of either expan sions from or destruction of their normal lattice structures, while the last one showed lattice expansion only. Heat treatments of these minerals in the vacuum caused them...

Introdução: A endometriose é uma doença inflamatória benigna, depen-dente de estrogênio, que afeta mulheres durante várias etapas sua evolu-ção biológica, desde a pré-menarca, passando pelo menecma e até mesmo no período pós-menopausa. Acredita-se terapia reposição hormo-nal possa aumentar recorrência da doença, dado seu efeito sobre os focos restantes na pelve. Relato caso: Paciente 38 anos fo...
