Tavaborole is a topical antifungal agent approved by the US Food and Drug Administration for the treatment of toenail onychomycosis. The effects of tavaborole on gestation, parturition (delivery, labor), offspring development, and survival during the perinatal and postnatal periods were assessed in mated female rats. Females (F0 generation) were administered single daily oral (gavage) doses of 15, 60, or 100 mg/kg/d from gestation day 6 through lactation day 20. The females were allowed to deliver naturally and rear their offspring until lactation day 21, at which time the F0 females were euthanized...

The toxicity effect of Concanavalin A (Canavalia ensiformis lectin, ConA) to bird cherry-oat aphid, Rhopalosiphum padi L. (Hemiptera: Aphididae), was investigated in the laboratory by using artificial diets containing ConA concentrations. Bird cherry-oat aphid performance was affected by the presence of Con A in artificial diets. The lectin added into the liquid diet increased the prereproductive period, mortality, and the average time of generation development (T) and decreased fecundity and the intrinsic rate of natural increase (rm)...

Calcium (Ca(2+))-activated chloride channels are fundamental mediators in numerous physiological processes including transepithelial secretion, cardiac and neuronal excitation, sensory transduction, smooth muscle contraction and fertilization. Despite their physiological importance, their molecular identity has remained largely unknown. Here we show that transmembrane protein 16A (TMEM16A, which we also call anoctamin 1 (ANO1)) is a bona fide Ca(2+)-activated chloride channel that is activated by intracellular Ca(2+) and Ca(2+)-mobilizing stimuli...

A hyperthermic syndrome (HS) associated with consumption of ration contaminated with Claviceps purpurea is described in 4 dairy cattle herds from different counties in the state of Rio Grande do Sul, southern Brazil. Outbreaks of this mycotoxicosis occurred during the summer of 1999-2000 and autumn of 2002 when 25% to 70% of cattle from those herds were affected. The disease occurred after the introduction of a new batch of feed contaminated with sclerotia of C. purpurea. First clinical signs were observed up to 3 mo after the ration was introduced and consisted of pyrexia, intense salivation and drooling, open-mouth, difficult breathing, in some cases with the tongue protruded, decrease in milk yield, decrease in food intake and weight loss...

AIM: To assess the effect of ICON (trade name of lambda-cyhalothrin) on sexual competence and fertility of male rats. METHODS: Male rats were gavaged daily for 7 consecutive days with different doses of ICON (63 mg/kg and 100 mg/kg) or vehicle (distilled water). Their sexual behaviour and fertility were evaluated at different time points during treatment and post-treatment using receptive females. RESULTS: Treatment had no effect on fertility, but sexual competence was seriously impaired: libido (assessed in terms of pre-coital sexual behaviour, and numbers of mounting, intromission and ejaculation), sexual arousability/motivation (in terms of latencies for mounting, intromission and ejaculation), sexual vigour (judged by frequencies of mounting and intromission or copulatory efficiency)...

Acute studies. Following oral or intraperitoneal administration, toxicity was very low (LD50 in rodents greater than 10,000 and greater than 900 mg/kg, respectively). Subacute and chronic studies in rodents. Signs of toxicity were seen only at doses of 400 mg/kg or more. Histopathological changes were found only in the 78-week study. Subacute studies in dogs (intravenous) and primates (oral). In dogs, doses of 0.1 and 0.3 mg/kg produced ataxia, salivation, and diarrhoea. In monkeys doses of 7 mg/kg or higher produced ataxia, increased appetite, hyperreflexive muscular spasms, increase in liver weight, and lipid depletion of the adrenal cortex...
