Four cultivars (Bronowicka Ostra, Cyklon, Tornado, and Tajfun) of pepper fruit Capsicum annuum L. were studied for phenolics contents and antioxidant activity. Two fractions of phenolics, flavonoids (with phenolic acids) and capsaicinoids, were isolated from the pericarp of pepper fruit at two growth stages (green and red) and were studied for their antioxidant capacity. Both fractions from red...

THREE types of reaction which will bring about the reduction of methylene blue added to milk have been known for a considerable time and have been utilised in various ways. (i) Schardinger [1902] has shown that milk contains an enzyme which is able to catalyse the reduction of methylene blue in the presence of an aldehyde. Trommsdorff [1909] has proved that the enzyme is a constituent of the mi...

Abstract. This research firstly aims to fabricate and characterize doped TiO2 nanoparticles (NPs) by iron Sulphur dopants, then the determination of photocatalytic activity NPs. Titanium tetraisopropoxide (TTIP), trichloride hexahydrate, thiouria, glacial acetic are utilized as precursors in hydrothermal method without using a template or surfactant. The synthesized NPs investigated X-ray diffr...

The collective behavior of secondary particles in pp interactions at 70 GeV/c is studied. A Two Stage Gluon Model is offered to describe processes with very high multiplicity. An active role of gluons is shown in multiparticle dynamics. The analysis of multiplicity distributions has revealed a possibility of a thermodynamic interpretation of these interactions. A mechanism of the soft photon pr...

The animals used were inbred Hartley strain guinea pigs (400-500 g), inbred Sprague strain rats (300400 g), and a purebred Dutch rabbit (1,300 g). Lymphocytes were obtained from the guinea pig and rat lymph nodes and the rabbit spleen. The animals were anesthetized with ethyl ether and exsanguinated via caridac puncture. The blood was defibrinated, and the serum was collected and filtered throu...

Biomolecules can be oxidized by free radicals. This oxidative damage has an important etiological role in aging and the development of diseases like cancer, atherosclerosis, and other inflammatory disorders. Synthetic antioxidants, like butylated hydroxyanisole, are good free radical scavengers, however, the synthetic antioxidants can be carcinogenic. Therefore, there is an increasing interest ...

Light has provided unparalleled control over when and where chemical transformations take place (spatiotemporal control), yet a third dimension emerged the incident color of light can tailor reactivity, termed here spectral control. Wavelength-selectivity in polymer science been influenced by pioneering reports light-driven isomerization (photoswitches), deprotection (photocages), coupling (cyc...
