The forebrain comprises an intricate set of structures that are required for some of the most complex and evolved functions of the mammalian brain. As a reflection of its complexity, cell migration in the forebrain is extremely elaborated, with widespread dispersion of cells across multiple functionally distinct areas. Two general modes of migration are distinguished in the forebrain: radial mi...
Diabetes Mellitus as a common metabolic disorder in women of reproductive age is rising throughout the globe. Diabetes in pregnancy has various adverse outcomes on different organs development including the central nervous system (CNS) and it can cause learning deficits, behavioral problems and motor dysfunctions in the offspring. The cerebellum is a part of brain that coordinates voluntary mov...
cementing is an essential part of every drilling operation. protection of the wellbore from formation fluid invasion is one of the primary tasks of a cement job. failure in this task results in catastrophic events, such as blow outs. hence, in order to save the well and avoid risky and operationally difficult remedial cementing, slurry must be optimized to be resistant against gas migration phe...
HTPB based composite Solid propellants are the source of power for the propulsion of rockets and missiles. Since composite solid rocket propellants, used in rockets and missiles is the fastest degrading component of the complete system, shelf life of the system is mainly governed by the life of the propellants. During storage and transportation, the propellant grains are subjected to various co...
Background: Colorectal cancer (CRC) is attributed as one of the most common malignancies worldwide. CD133 molecule, as a pentaspan transmembrane glycoprotein, confers stem cell-related characteristics, including self-renewal and multi-directional differentiation capability. CD133 plays important roles in the progression of CRC by conferring apoptotic resistance and migration ab...

Insulation of solid propellant to controlling and limiting the burning surface and also to avoid of heat transfer to the solid rocket body is done. This type of coating is defined as inhibitors of combustion. Unsaturated polyesters such as polyurethane are used for good chemical compatibility between double base propellant and inhibitor. In this article, the effect of aromatic groups and the ef...
Human settlements experience continual change. In recent years, many rural areas have experienced dispersed grow (rural sprawl) and population declines in traditional village centers (Hollowing). These paradoxical phenomena have occurred in most developing countries, including rural Iran. This study examines this phenomena in three Iranian villages of Kahak area of Qom province, and develops a ...
in this paper the histopathological observation of the migratory phase of schistosome larvae (schistosomulae) in the laboratory animal were studied. the first tissue samples were taken from the skin of infected animals 30 minutes after exposure to the cercariae and continued daily up to 40 days post infection. the tissue specimens were taken from skin, liver. lung, lymph nodes, kidney, brain, b...
