Vitamin D3 and zinc supplements augment the antimanic efficacy of lithium and olanzapine treatments in an animal model of mania.

Bipolar disorder (BD) is a challenging psychiatric disorder and a complex disease. The associated reduction in serum vitamin D (VitD) levels in BD patients and the contribution of zinc (Zn) to the treatment, along with the severe side effects of lithium (Li) treatment, were encouraging to assess the efficacy of different correlated combinations of therapeutic/nutraceutical treatments such as olanzapine (Oln), VitD and Zn against Li. Mania was induced in C57BL/6 mice by administering methylphenidate (MPH) for 14 consecutive days.

Improvement of the antioxidant activity of thyme essential oil against biosynthesized titanium dioxide nanoparticles-induced oxidative stress, DNA damage, and disturbances in gene expression in vivo.

Background: Titanium dioxide nanoparticles (TiO-NPs) are widely utilized in medicine and industry; however, their safety in biological organisms is still unclear. In this study, we determined the bioactive constitutes of thyme essential oil (TEO) and utilized the nanoemulsion technique to improve its protective efficiency against oxidative stress, genotoxicity, and DNA damage of biosynthesized titanium dioxide nanoparticles (TiO-NPs).

Methods: TEO nanoemulsion (TEON) was prepared using whey protein isolate (WPI).

Assessment of the Oxidative Damage and Genotoxicity of Titanium Dioxide Nanoparticles and Exploring the Protective Role of Holy Basil Oil Nanoemulsions in Rats.

This study was designed to evaluate the oxidative damage, genotoxicity, and DNA damage in the liver of rats treated with titanium nanoparticles (TiO-NPs) with an average size of 28.0 nm and ξ-potential of - 33.97 mV, and to estimate the protective role of holy basil essential oil nanoemulsion (HBEON).

Osteoarthritis complications and the recent therapeutic approaches.

The accelerated prevalence of osteoarthritis (OA) disease worldwide and the lack of convenient management led to the frequent search for unprecedented and specific treatment approaches. OA patients usually suffer from many annoying complications that negatively influence their quality of life, especially in the elderly. Articular erosions may lead eventually to the loss of joint function as a whole which occurs over time according to the risk factors presented in each case and the grade of the disease.

Biosynthesis of gold nanoparticles for the treatment of osteoarthritis alone or in combination with Diacerein in a rat model.

Gold (Au) compounds were used as an effective therapeutic agent for various inflammatory diseases; however, the use of Au compounds becomes limited because of its association with several side effects. Hence, gold nanoparticles (AuNPs) were developed as a new option for the medical proposes. However, the safety evaluation of gold nanoparticles (AuNPs) in osteoarthritis (OA) treatment remains vague.

Neurobehavioral effects of alcohol in overcrowded male adolescent rats.

Being a critical neurodevelopmental stage that is affected by social conditions, the period of adolescence was chosen as the age of examining possible modification of alcohol neurobehavioral effects by overcrowding. Adolescent male rats (postnatal day 35±1) were subjected to overcrowding and/or injected with ethanol, 2 g/kg, 20% w/v, (i.p.

Encapsulation of cinnamon oil in whey protein counteracts the disturbances in biochemical parameters, gene expression, and histological picture of the liver and pancreas of diabetic rats.

This study aimed to evaluate the protective role of encapsulated cinnamon oil emulsion (COE) in whey protein concentrate (WPC) against the disturbance in lipid profile, oxidative stress markers, and gene expression in streptozotocin (STZ)-treated rats. COE was analyzed using GC-MS, and the emulsion was prepared and characterized. In the in vivo study, six groups of male rats were treated orally for 4 weeks, including the control group, the group treated with STZ (D-rats), the groups received a low or high dose of COE (200 or 400 mg/kg B.
