Insects, like other organisms, must deal with a wide variety of potentially challenging environmental factors during the course of their life. An important example of such a challenge is the phenomenon of oxidative stress. This review summarizes the current knowledge on the role of adipokinetic hormones (AKH) as principal stress responsive hormones in insects involved in activation of anti-oxid...

A sequential injection chromatography (SIC) constructed from a short monolithic column and a microfluidic polymer chip with an embedded Cl ion-selective electrode (Cl-ISE) as a detector was developed for simultaneous determination of common inorganic anions. Under the optimal flow conditions of the SIC system, the determination range for Cl, NO2 , Br, NO3 ions was as follows: For Cl ion in a co...

Keloid is a benign fibroproliferative tissue growth that exceeds the initial wound margins. Captopril has been tested in vitro to reduce fibroblast proliferation and collagen deposition; thus, it potential for use treatment of keloids. Meanwhile, 5‐fluorouracil (5‐FU) already used keloid management. This study aimed determine efficacy combination captopril 5‐FU cultures. tissues were cultured u...

some 2-iminothiazolidin-4-ones have been synthesized by the reaction of dialkyl acetylenedicarboxylates with thiosemicarbazones. the reaction was performed in the presence of 10 mol% of triphenylphosphine and tetrabutylammonium bromide as a phase transfer catalyst in water as a green solvent. all the synthesized compounds were characterized by their physical and spectral data.

BACKGROUND Endothelial nitric oxide (NO)-mediated responses are impaired in arterioles of male spontaneously hypertensive rats (SHR), but they are still present in female SHR. We hypothesized that in vitro incubation of arterioles of male SHR with estrogen will restore NO-mediated responses by upregulation of endothelial NO synthase. METHODS AND RESULTS Responses to increases in perfusate flo...

Pyronaridine and artesunate have been shown to be effective in falciparum malaria treatment. However, pyronaridine is rarely used in Hainan Island clinically, and artesunate is not widely used as a therapeutic agent. Instead, conventional antimalarial drugs, chloroquine and piperaquine, are used, explaining the emergence of chloroquine-resistant Plasmodium falciparum. In this article, we invest...

Intracranial injection of eel angiotensin II (eANG II, 5x10(-13)-5x10(-8) mol), acetylcholine (ACh, 5x10(-12)-5x10(-9) mol), substance P (5x10(-10) mol) and isoproterenol (a beta-adrenoceptor agonist, 5x10(-11)-5x10(-9) mol) enhanced water intake in the seawater eel. The effects of eANG II, ACh and isoproterenol were dose-dependent. By contrast, water intake was inhibited by intracranial inject...

In this study, the effect of 1,2,3-trichloropropane (TCP) as trifunctional monomer on thermophysical properties of synthesized poly(ethylene tetrasulfide) (PETS) is investigated. To this end, different amounts of TCP (0-40 mol. % of halide-containing monomer) were incorporated into the structure of polysulfide polymer via interfacial condensation polymerization. Measuremen...
