Vitiligo is brought on by functional melanocyte loss and manifests as white maculae that may cover the whole body's skin. There a genetic background in pathogenesis of vitiligo. Polymorphisms different parts catalase gene affect disease activity result less catalase, thus, accumulation hydrogen peroxide, one oxidative factors damage melanocytes. We evaluated CAT 262 polymorphism vitiligo patien...

To determine some physiological and biochemical changes in Capsicum annuum L. grown in vitro, the effects of different Cu concentrations on this plant were investigated. Cu was applied in the form of Cu sulfate (CuSO4) in three levels (0, 0.1, and 0.2 mM) and at three times (days 8, 10, and 12). With Cu treatments, superoxide dismutase (SOD), catalase (CAT) activities, and total phenolic compou...

Biomimetic engineering presents an insightful strategy to access fascinating biocomposites integrating biological, chemical, and material functions. Herein, a new self-propelled hydrogen-bonded enzymatic framework through biomimetic bottom-up is reported. The metal-free, mesoporous, photoactive organic (HOF) exoskeleton in situ grown around catalase (CAT), enzyme well known for its ability the ...

Noise-induced hearing loss (NIHL) is an important occupational hazard that results from an interaction between genetic and environmental factors. Although the environmental risk factors have been studied quite extensively, little is known about the genetic factors. On the basis of multiple studies, it was proposed that oxidative stress plays an important role in the development of NIHL. Here, w...

In the present study, oxidative damage parameters in preeclamptic pregnant women were investigated and compared with healthy tissues. Antioxidant enzymes determined 53 placentas. The of free oxygen radicals placental tissue was by measuring antioxidant enzyme systems (The amounts lipid peroxidation (LPO), glutathione (GSH) catalase (CAT), myeloperoxidase (MPx) activities nitric oxide levels (NO...

The aim of this study was to investigate the effects of catalase and pre-freezing equilibration during ram sperm cryopreservation on motility and membrane and acrosomal integrity of frozen-thawed semen, as well as conception rate following laparoscopic timedinsemination. Semen was collected from four mature Dorper rams, pooled and diluted in Tris egg-yolk extender basic solution (CON), or this ...

The hybrid nanoparticles of amorphous calcium phosphate (ACP)-catalase (CAT) developed by in situ biomineralization can create a stable semi-aqueous nanoscale environment for entrapped proteins against thermal denaturation. This finding indicates the importance of an amorphous mineral phase in the preservation of organic macromolecules.

Oxidative stress is believed to initiate and aggravate many diseases including peptic ulcers and gastric carcinoma. We observed an increase in rat gastric mucosal lipid peroxidation (LPO) and superoxide dismutase (SOD) and a decrease in catalase (CAT) levels in cold restraint stress-induced gastric ulceration while, in clinical peptic ulceration and gastric carcinoma patients, an increase in se...

This study was carried out to assess the developmental pattern of copper- and zinc-containing superoxide dismutase (CuZnSOD), manganese-containing superoxide dismutase (MnSOD), glutathione peroxidase (GSH-Px) and catalase (CAT) activity in rat brain. The enzymes studied were assayed in different brain regions (cerebral cortex, striatum, cerebellum and brainstem) and enzyme values were corrected...
