Over the past decade, cold atmospheric plasma (CAP) has undergone extensive research as a promising therapeutic approach in oncology, with different treatment methods and exposure configurations being investigated resulting various biological effects, most of them after long or durations. This study aimed to evaluate potential custom-made CAP generation source produce plasma-activated medium (P...

Nitrate and nitrite are reaction products that result, for example, from the application of nitrogenous fertilizers to agricultural land. That part nitrogen not absorbed by plants can pass into groundwater in form nitrate or nitrite. This also lead contamination drinking water via groundwater, with all its negative side effects. In present article an automatic system is presented, which perform...

It is known that the adjoint representation of any Kac-Moody algebra A can be identified with a subquotient of a certain Fock space representation constructed from the root lattice of A. I define a product on the whole of the Fock space that restricts to the Lie algebra product on this subquotient. This product (together with a infinite number of other products) is constructed using a generaliz...

A sequential injection system for the determination of nitrate (NO3 ) in vegetables was developed to automate this determination, allowing for substantially reduced reagent consumption and generated waste using low-cost equipment. After extraction with water and filtration, the extracted nitrate is reduced inline to nitrite in a copperized cadmium (Cd) column and determined as nitrite. Accordin...

In order to study the possible role of nitric oxide (NO) in the human placenta, we measured the concentration of its stable metabolite nitrite (NO2-) in the placentas of women with normal pregnancies and those from pregnancies complicated by intrauterine growth restriction (IUGR) with or without fetal hypoxia. We have measured nitrites by the Griess reaction in 15 placentas from IUGR pregnancie...

BACKGROUND recent reports have suggested the applicability of salivary amino acids as markers for various diseases. In order to understand the role of macrophages in the age-related changes of salivary amino acid composition, we compared the amino acid production and consumption between control and activated macrophages. MATERIALS AND METHODS mouse macrophage-like cells (RAW264.7, J774.1) wer...

The sporadic simple group F2 known as Fischer's Baby Monster acts flag-transitively on a rank 5 P-geometry G(F2). P-geometries are geometries with string diagrams, all of whose nonempty edges except one are projective planes of order 2 and one terminal edge is the geometry of the Petersen graph. Let AC be a flag-transitive P-geometry of rank 5. Suppose that each proper residue of K is isomorphi...

− The aim of this study was to evaluate the anti-diabetic effects of the water extract of Lespedeza cuneata (LCW) using rat insulinoma (RIN) m5F cells and streptozotocin (STZ)-induced diabetic rats. The effect of LCW on the protection of pancreatic beta cells was assessed using MTT assay, and nitric oxide production was assessed using Griess reagent. STZ-induced diabetic rats were treated with ...

The purpose of the present study was to investigate antitumour and anti-inflammatory activities of flavonoids isolated from Byrsonima crassa, Davilla elliptica and Mouriri pusa. The antitumour activity was measured by the MTT assay in murine mammary tumour cells (LM2) and the IC50 values of the flavonoids tested ranged from (31.5 +/- 2.97) to (203.1 +/- 5.9) microg/ml. The flavonoids 1 (myricet...

In this study, we investigated the role of nitric oxide metabolism and lipid peroxidation in patients with P. vivax malaria. The levels of nitrite and nitrate were analyzed using a procedure based on the Griess reaction and malondialdehyde levels which index of lipid peroxidation was determined by thiobarbituric acid reaction. The levels of nitrite/nitrate and malondialdehyde in patients were h...
