OBJECTIVE Our aim was to investigate the glutathione-disulfide system of antioxidant defense in men with different body mass index and infertility. METHODS 60 men with infertility were examined--30 with normal weight and 30 with overweight. 30fertile men were included in the control group. Hemolysate made from red blood cells was used as a materialfor study. The level of reduced (GSH) and oxi...

Liquid chromatography is a widely popular technique in clinical laboratories and clinical applications. People evolved and developed various types of chromatography for decades after its initial idea published in 1960s. Mostly people use HPLC-MS, UHPLC techniques to purify antibody, drug isomers and enantiomers. Separating molecules of different sizes by modified HPLC and size exclusion chromat...

Simple, accurate and precise ultraviolet spectrophotometric and reversed-phase high-performance liquid chromatographic (RP-HPLC) methods for simultaneous estimation of amlodipine besylate (AMLO) and olmesartan medoxomil (OLME) in combined tablet dosage form have been developed and validated. Beer’s law was obeyed in the concentration range of 5-70 and 5-60 μg/mL in methanol at 238 nm and 257 nm...

 Methods: The soluble solids content determined by measuring Brix 20°C using a digital refractometer. Ash was combustion s...

Introduction. To date, the use of unmanned aerial vehicles (UAVs) in Ukraine for agricultural lands treatment is a new promising technology that requires detailed study and development approaches to risk assessment hygienic regulation. Development method will allow measuring content diamond blue FCF sorption material (filter paper) relevant. The aim – determining synthetic dye by high-performan...

The chemical composition of the essential oil obtained from aerial parts of Galium verum L. (Rubiaceae) from Iran was examined by a combination of GC and GC/MS. The oil isolated by hydro-distillation using a Clevenger-type apparatus. Air-dried aerial parts of Galium verum (80 g) which were collected from Bomehen in Tehran province at full flowering stage on May 2003, were subjected to hydro-dis...

Photocatalysis application in water treatment has been the object of many researchers worldwide recent decades. However, there are limited commercial applications due to low photon transfer efficiency, which create barriers leading challenges making process efficient and economically feasible. Fixed UV/visible light sources, generally located outside reactor or encapsulated quartz tube inside s...

Otimizou-se método para monitoração plasmática de bussulfano em pacientes submetidos a transplante células-tronco hematopoiéticas (TCTH). Utilizou-se HPLC-PDA Shimadzu, coluna C18 (150 mm x 4 mm), metanol/água/acetonitrila (65:20:15, v/v/v), fluxo 1 mL min-1; UV λ = 276 nm, tempo análise 17 min; derivatização com dietilcarbamato sódio, extração acetato etila; curva calibração linear 200-5000 ng...
