the discharge of lead containing effluents into the environment and water bodies is harmful for the human, animals, aquatic flora and fauna. herein, a novel surface engineered magnetic nanoparticle for removing pb2+ ions was studied. after surface modification of the magnetite by 3-amino-propyltriethoxysilane (aptes) magnetic nanoparticles with covalently linked porphyrins were synthesized. two...

BACKGROUND Paradoxical excitement response during sedation consists of loss of affective control and abnormal movements. Chronic alcohol abuse has been proposed as a predisposing factor despite lack of supporting evidence. Because alcohol and propofol have a common site of action, we postulated that paradoxical excitement responses during propofol-induced sedation occur more frequently in hazar...

Metformin is one of the most extensively used drugs, making it likely endocrine disruptors in environment, which may negatively affect fish and other freshwater animals. Still, there a dearth studies examining metformin’s impact on creatures, like fish. This research aimed to identify biochemical genotoxicity effects disruptor metformin Labeo rohita at ecologically appropriate doses. Metformin’...

Babesia ovis plays an important role in causing anemia and kidney dysfunction in affected animals. There are few extensive studies about hematological and biochemical findings of small ruminants' babesiosis caused by B. ovis. The aim of this study was to evaluate the effect of babesiosis on some hematological and biochemical parameters in infected small ruminants with B. ovis. A total of 280 sh...

As a rule, all species of animals are regulated by other living organisms (antagonists) which are not under manipulation by man but they are naturally occurring in our surrounding environment. The process called natural biological control when man attempts to use naturally occurring antagonists to lower a pest population which would cause losses to plant or animals. Biological control is an eco...

Background: Media advertisements especially radio and TV are one of the most important and effective ways for health promotion and consumption of healthy productions worldwide. Ministry of Health and some other ministries in Iran agreed to control and restrict the advertising of unhealthy products and services. Therefore, adequate supervision and monitoring should be done in this field.  A...

The beneficial effects of oxygen are widely known, but the potentially harmful effects of high oxygenation concentrations in blood and tissues have been less widely discussed. Providing supplementary oxygen can increase oxygen delivery in hypoxaemic patients, thus supporting cell function and metabolism and limiting organ dysfunction, but, in patients who are not hypoxaemic, supplemental oxygen...

cinnamon has many therapeutic effects, such as its impact the increase of sexual ability. this experiment was conducted to determine the effect of cinnamon extract on spermatogenesis and hormonal axis of pituitary gonad in mice. the animals used in this study are male adult mice (weighing about 30-34 g and 9-10 weeks old). cinnamon was purchased from one of the most valid shops in jahrom and th...

Two previously isolated Lactobacillus strains (L. fermentum HM3 from human milk and L. buchneri FD2 from fermented dates), intended as probiotic for human, were assessed for their safety using acute and subacute oral toxicity tests in rats. In addition, their effects on cecal microflora and harmful bacterial enzymes (β-glucuronidase and β-glucosidase) of the tested animals were also determined....

Studies indicate that more students are opposing the use of invasive procedures on animals. When students are forced to use animals in ways that they view as harmful, painful, stressful or lethal to the animals, several reactions may occur. Such students may suffer psychological trauma as the result of seeing themselves or others engaged in behaviour that they find ethically objectionable. Thei...
