background: diabetes mellitus (dm), primary or idiopathic is a chronic disorder of the carbohydrate, lipid and protein metabolism. dm may impact male reproductive function at several levels. it is shown that dm has detrimental effects on sperm parameters in human and experimental animals. objective: the aim of this study was to observe the effects of diabetes on sperm parameters (viability, cou...

Eavesdropping on communication is widespread among animals, e.g. bystanders observing male-male contests, female mate choice copying and predator detection of prey cues. Some animals also exhibit signal matching, e.g. overlapping of competitors' acoustic signals in aggressive interactions. Fewer studies have examined male eavesdropping on conspecific courtship, although males could increase mat...

Pesticides are important agents that intentionally introduced into the environment to control various pests and disease carriers, often by killing them. Although pesticides have many objectives, including protection against crop loss vector-borne diseases, there significant concerns over potential toxicity of on organisms, humans. The frequent use in agriculture has led long-term exposure human...

In the present study, the effects of pregnant NMRI mice restraint stress on the responsibility of their children to the behavioral properties of morphine, sulpiride and dextromethorphan were investigated in the F2 generation. Twenty four pregnant NMRI female mice (W: 25 g) were divided into the experimental and control groups (n = 12/group). Animals in the experimental group were kept in the r...

The kidney's responsiveness to male sexual hormones has been often neglected. Renal secretion of organic anions is higher in male than in female individuals; as a consequence, most of the xenobiotics that are excreted from the organism through this pathway are eliminated more rapidly by males than by female animals. To gain further insight into this issue, we studied in vitro and in vivo charac...

Nature conservation in Namibia today depends on the commercialization of wildlife, which combines efforts with touristic and thus market-oriented targets. In our paper, we frame this trade as an economy visual, production visual encounter value sale particular experiences wild animals are essential. Employing a ‘posthuman political ecology visual’ critically analyze guided game views forced pre...

On the model of premature aging induced by 30-day dark deprivation (light-dark cycle 24/0 h, artificial illumination 300 Lux), effect exogenous melatonin (0.3 mg/kg, 14 days after cancellation deprivation, intragastric dailyin 2 % starch mucus) on dynamics body weight and level Klotho protein in blood was studied outbred white male rats 4 months age. It has been shown that prolonged is accompan...

The behavioral responses of Branchipus schaefferi Fisher, 1834 males and females to short-term thermal stress in six different rearing conditions are studied. swimming performance was tested pure tap water collected from both male female culture mediums. animal's behavior recorded using a high-definition digital video camera mounted approximately 30 cm above the experimental containers. track t...

Repeated administration of nicotine causes incentive and behavioral sensitization in animals. Ascorbic acid administration inhibits some effects of nicotine. In the present study, the effect of ascorbic acid administration on nicotine-induced behavioral sensitization in Male Swiss-Webster mice (20-25 g) was investigated. Animals were injected with nicotine (0.25 mg/kg, i.p.) once daily for seve...
