Efficacy of goldenberry in improving obesity-induced hemoglobin conformational structure changes in wistar rats: A biophysical perspective.

The relationship between obesity and the conformational structure of hemoglobin (Hb) has not been extensively investigated. This study aims to elucidate the dielectric parameters that distinguish the Hb molecule under obese conditions and following treatment with goldenberry (GB) extract, compared to a control group. The dielectric parameters analyzed include the loss factor (D), relaxation time (τ), dielectric increment (Δε), relative permittivity (έ), dielectric loss (ε"), conductivity (σ), and Cole-Cole parameters (α), measured across a frequency range of 20 Hz to 3 MHz.

Role of Goldenberry (Fruits with Husk) Extract in Ameliorating the Architecture and Osmotic Fragility of Red Blood Cells in Obese Rats.

Goldenberry (GB) is a promising fruit that can be a constituent in many possible nourishments. No notifications were obtained regarding the impact of exposure to goldenberry extract in the viewpoint of blood rheological properties as well as erythrocyte osmotic fragility of red blood cells (RBCs) in obese rats. A substantial reduction in plasma triglyceride, total cholesterol, and LDL, with a considerable increment in HDL levels relative to the obese group ( ≤ 0.

Nano cerium oxide and cerium/zinc nanocomposites characterization and therapeutic role in combating obesity via controlling oxidative stress and insulin resistance in rat model.

Background: CeONPs and ZnONPs can curb the increase of cholesterol and triglycerides observed in rats with non-alcoholic fatty liver disease. It was suggested that CeO NPs could potentially have an insulin-sensitizing effect, specifically on adipose tissue and skeletal muscle. It was reported that ZnONPs combat the increase of insulin resistance observed in obese rats and could be beneficial value in NAFLD.

Zinc nanoparticles ameliorated obesity-induced cardiovascular disease: role of metabolic syndrome and iron overload.

Obesity is a complicated disease characterized by abundant fat accumulation. It is associated with cardiovascular disease. The current study aimed to appreciate the role of synthesized zinc oxide nanoparticles (ZnONPs) (18.

Potential effects of the combination of nicotinamide, vitamin B2 and vitamin C on oxidative-mediated hepatotoxicity induced by thioacetamide.

Background: The liver disease is one of the most important traditional public health problems in Egypt. Oxidative stress is attributed to such pathological condition that further contributes to the initiation and progression of liver injury. In the present study, we have investigated if the strong antioxidant power of Nicotinamide (NA), Vitamin B2 (VB2), and Vitamin C (VC) can ameliorate TAA-induced oxidative stress-mediated liver injury in the rats.

The changes in serum and whole blood rheological properties of rabbits during the progression of atherosclerosis.

This study aimed to evaluate the role of zinc (Zn)-supplemented with high cholesterol diet (HCD) on the serum and whole blood rheological properties of rabbits fed a HCD. Twenty-four New Zealand white rabbits were divided into three groups. The HCD group was fed a diet with 1.

Determination of Human Hemoglobin Derivatives.

The levels of the inactive hemoglobin (Hb) pigments [such as methemoglobin (metHb), carboxyhemoglobin (HbCO) and sulfohemoglobin (SHb)] and the active Hb [in the oxyhemoglobin (oxyHb) form] as well as the blood Hb concentration in healthy non pregnant female volunteers were determined using a newly developed multi-component spectrophotometric method. The results of this method revealed values of SHb% in the range (0.0727-0.

The effects of intraperitoneal administration of gold nanoparticles size and exposure duration on oxidative and antioxidants levels in various rat organs.

As one of the toxic mechanism of nanoparticles (NPs), the reactive oxygen species (ROS) generation which has been widely studied. Nevertheless, the link between GNPs and antioxidant and oxidative stress markers has not been well established. The effects of gold nanoparticles (GNPs) size and exposure duration on antioxidant and oxidative stress markers including reduced glutathione (GSH), super oxide dismutase (SOD), glutathione peroxidase (GPx), glutathione reductase (GR), total antioxidant capacity and malondialdehyde (MDA) were evaluated in different rat organs.

The gold nanoparticle size and exposure duration effect on the liver and kidney function of rats: In vivo.

Unlabelled: Nanoparticles (NPs) offer a great possibility for biomedical application, not only to deliver pharmaceutics, but also to be used as novel diagnostic and therapeutic approaches. Currently, there are no data available regarding to what extent the degree of the toxicity and the accumulation of gold nanoparticles (GNPs) are present in in vivo administration. This study aimed to address the GNP size and exposure duration effect on the liver and kidney function of rats: in vivo.

Biochemical changes of hemoglobin and osmotic fragility of red blood cells in high fat diet rabbits.

The aim of this study was to assess the effects of hyperlipidemia on auto-oxidation rate of hemoglobin (Hb; absorbance at 630 nm versus time), Hb derivatives and osmotic fragility of Red Blood Cells (RBCs). These parameters were measured in twenty five 12-week-old male New Zealand white rabbits fed on a High Fat Diet (HFD) for a feeding period of 10 weeks. We found that Hb concentration and RBC count were significantly decreased while white blood cell and platelet counts were significantly increased in HFD rabbits compared with control rabbits.

Elucidation of the effects of a high fat diet on trace elements in rabbit tissues using atomic absorption spectroscopy.

Background: The mechanism of atherogenesis is not yet fully understood despite intense study in this area. The effects of high fat diet (HFD) on the changes of trace elements [iron (Fe), copper (Cu) and zinc (Zn)] in several tissues of rabbits have not been documented before. Thus, the aim of this study was to elucidate the changes in trace elements in several tissues of rabbits fed on HFD for a period of feeding of 10 weeks.
