or they growth arrest at subconfluence in serum-deficient medium (17,20).The quiescentcellscanthenbe stimulated to undergo a round of DNA synthesis by adding serum (26, 29) or purified mitogens including EGF3(3, 11, 23), FGF (10), or the tumor promoter, TPA (21, 25). DNA virus transformed cells, on the other hand, do not growth arrest in G, under usual monolayer culture conditions. Theyeither b...

Nowadays the application of nanotechnology in different biomedical fields such as drug delivery is increasing due to its unique advantages. With this in mind, it is widely believed that nanogels as the nanometer-sized networked polymeric particles have a considerable impact on drug delivery systems as biocompatible nanocarriers due to their unique characteristics such as high loading capacity, ...

ABSTRACT: The essential oil of plant material is the fraction isolated by means of several methods such as liquid carbon dioxide, microwaves and low or high pressure distillation employing boiling water or hot steam and is chemically defined as terpenoids namely monoterpene and the oxygenated form. Since these compounds might be employed as flavour contributors due to their chemical nature, it ...

Aims: Pigmentation disorders are one of the main skin problems due to mustard gas exposure in chemically-injured veterans. The aim of this study as part of the Sardasht cohort study was to investigate the association between IL-6 and IL-4 and pigment disorders in chemically-injured veterans exposed to mustard gas. Materials & Methods: In this study, 500 subjects including 372 people expose...

Nanoscale heterostructures with quantum dots, nanowires, and nanosheets have opened up new routes toward advanced functionalities and implementation of novel electronic and photonic devices in reduced dimensions. Coherent and passivated heterointerfaces between electronically dissimilar materials can be typically achieved through composition or doping modulation as in GaAs/AlGaAs and Si/NiSi or...

Background and Objectives: A wound is an injury or rupture on the surface of skin, which is caused physically, chemically, mechanically, or by heat.   Case Report: The patient was a one-month-old infant who admitted to the hospital with seizure. After physical examination, it was revealed that the left thigh had an extensive skin necrosis due to burn. After the debridement of the lesion, due ...

Clinoptilolite zeolite was chemically modified with sodium, calcium, or magnesium to comparatively study the physical recovery of ammonium and phosphates from simulated blackwater.
