TNF-alpha has numerous biological activities, including the induction of chemokine expression, and is involved in many gastric injuries. C-C chemokines [monocyte chemotactic protein (MCP)-1 and macrophage inflammatory protein (MIP)-1alpha] and C-X-C chemokines [MIP-2 and cytokine-induced neutrophil chemoattractant (CINC)-2alpha] mediate chemotaxis of monocytes and neutrophils, respectively. We ...

OBJECTIVE We evaluated the effect of acute hypergravity (HG) on the immune response in a murine model of allergic asthma. MATERIAL AND METHODS Twenty-eight BALB/c mice were used. Group A (control group, n = 7) mice were sensitized and challenged with normal saline. Group B (control HG exposure group, n = 7) mice were sensitized, challenged with saline, and exposed to acute HG (+10 Gz) for 4 h...

In his seminal paper on the solution of infiltration equation, Philip (1969), https://doi.org/10.1016/b978-1-4831-9936-8.50010-6 proposed a gravity time, tgrav, to estimate practical convergence time and domain validity infinite series expansion, TSE, for describing transient state. The parameter tgrav refers point in where is dominated equally by capillarity as derived from first two (dominant...

Background and Aims: Ecstasy or 3, 4-methylenedioxymethamphetamine (MDMA) is a brain stimulant and a hallucinogenic material prepared by chemical changes in amphetamine. The aim of this study was to evaluate the changes induced by this drug in mouse cardiac histopathology, electrocardiogram (ECG) and blood cell counts. Materials and Methods: In this experiment, 3 groups (n=10) of mice were e...

flood spreading stations were constructed in iran with different objectives such as groundwater recharge and vegetation recovery. accumulation of sediment can be a major problem in flood spreading stations. according to generally accepted theories, floods and salt pollution can reduce gradually the infiltration rate. in order to investigate this issue, 13 flood spreading stations were selected ...

lymphocytic infiltration of jessner-kanof is a chronic, benign t cell infiltration disorder of exposed skin with unknown etiology. in some instances, these lesions are induced or aggravated by light exposure. in this case report, we are going to describe an interesting occupationally related skin disease, jessner's disease, after several years working with computer. on the basis of literature r...

Perforation of a hollow viscus is an acute abdominal drama and the accurate diagnosis highly depends on demonstration of free intra­pritoneal air. The importance of adequate examination in the demonstration of ,tiny amount ()ff air is stressed and the value of an upright chest film when the horizontal beam is tangential to the top of the diaphragm is mentioned. Before standing for chest x-ray t...

use of the double ring infiltrometer to measure soil water infiltration in center pivot irrigation systems isn’t an accurate approach because the real conditions of infiltration under center pivot sprinklers is different from what happens in the double ring. in this study the infiltration parameters were evaluated in real conditions of a center pivot system. for this purpose a single ring with ...

ABSTRACT- To study the effect of tree roots on increasing water infiltration in soil and also to determine and assess the coefficients of different infiltration models, some infiltration tests were performed in three tree plantation areas in Badjgah, Fars province with different soil textures (clay loam for pear plantation, sandy loam for grape plantation, loamy sand for pine trees). In each pl...
