OBJECTIVE Today, esophageal cancer (EC) has become one of the most common cancer types in China. Therefore, new drug and therapeutic strategies are urgently needed to improve postoperative survival rate of patients with EC. As a food additive, several lines of evidence have shown that citric acid can be served as glycolysis suppressor to inhibit growth of some tumor cells. However, little is kn...

background: functional defects in mitochondria are involved in the induction of cell death in cancer cells. the process of programmed cell death may occur through the mechanisms of apoptosis. several potential lead molecules such as camptothecin (cpt) and its analogues have been isolated from plants with anticancer effect. the aim of the present study was to understand the necrotic effect versu...

The objective of this study was to present a classification of the root development stage of female rat molar teeth and to evaluate the variation in the lactate dehydrogenase (LDH) activity and electrophoretic isoenzyme profile according to the stage of root development of the molar teeth. We also studied the LDH activity and isoenzymes of the pulp of incisor teeth. The stage of development of ...

IT IS known that enzyme distribution is not the same among various fibre tracts, but except for LUBLINSKA’S (1 962) report of a proximo-distal decrease of cholinesterase along peripheral nerves there is little information about differences of enzyme activity along the course of a given fibre tract. This paper presents biochemical and histochemical data of the distribution of lactate dehydrogena...

BACKGROUND Opioid preconditioning protects the myocardium against ischemia/reperfusion (IR) injury. By enhancing cardiomyocyte viability, opioids can enhance cardiac function and recovery from IR injury during acute cardiac care. The myocyte model HL-1 is an immortalized, mouse atrial cell line that expresses functional delta-opioid receptors. The HL-1 myocyte may be useful for IR injury resear...

there is a great concern about the effect of propoxur, as one of the more common n-methyl carbamate pesticides, on human health due to its extensive use in agricultural and non-agricultural applications. caco-2 cells became resistant to propoxur, and the resistance was confirmed through mtt assay. then the cell membrane integrity and p-glycoprotein expression were measured by ldh assay and west...

Testis-specific lactate dehydrogenase (LDH-C₄) is one of the lactate dehydrogenase (LDH) isozymes that catalyze the terminal reaction of pyruvate to lactate in the glycolytic pathway. LDH-C₄ in mammals was previously thought to be expressed only in spermatozoa and testis and not in other tissues. Plateau pika (Ochotona curzoniae) belongs to the genus Ochotona of the Ochotonidea family. It is a ...

AIM The increased consumption of traditional medicinal plants has been driven by the notion that herbal products are safe and efficient. The purpose of this study was to evaluate the safety and the protective effect of a hydro alcoholic extract of Desmodium adscendens (DA) on liver (HEPG2) and kidney (LLC-PK1) cells. MATERIALS AND METHODS A hydro alcoholic extract of DA was used. HEPG2 or LLC...
