To examine the action mechanism that mediates the anti-fertility effect of Costus speciosus extract, research was conducted on male Sprague-Dawley rats. Costus extract was given to male rats for 14 days at various doses, namely 275, 550 and 1,100 mg kg-1 day-1 in 0.5% sodium CMC. The results showed that Costus extract with doses ranging from 275 to 1,100 mg kg-1 day-1 was able to inhibit pregnancy among female rats by 10-70%. No obstacles in terms of sexual behavior were identified among male rats. The anti-fertility effect of Costus extract kicked in without involving a decreased level of male reproductive hormones...

Prenatal exposure to alcohol causes a wide range of deficits known as Fetal Alcohol Spectrum Disorders (FASDs). Many factors determine vulnerability to developmental alcohol exposure including timing and pattern of exposure, nutrition, and genetics. Here, we characterized how a prevalent single nucleotide polymorphism in the human brain-derived neurotrophic factor (BDNF) gene (val66met) modulates FASDs severity. This polymorphism disrupts BDNF's intracellular trafficking and activity dependent secretion, and has been linked to increased incidence of neuropsychiatric disorders such as depression and anxiety...

Alcohol (ethanol) is one of the most widely used psychoactive substances worldwide. Alcohol consumption during pregnancy may result in a wide range of morphological and neurodevelopmental abnormalities termed fetal alcohol spectrum disorders (FASD), with the most severe cases diagnosed as fetal alcohol syndrome (FAS). FAS and FASD are not readily curable and currently represent the leading preventable causes of birth defect and neurodevelopmental delay in the US. The etiology of FAS/FASD remains poorly understood...

Offspring of female rats fed either a casein (CAS) diet or a low-isoflavone soy protein isolate (SPI) diet were compared in an animal model of chronic ethanol consumption to investigate whether maternal diet regulates the adaptive responses of offspring to postnatal ethanol exposure and potentially affects the development of liver disease in later life. Female rats were fed either a CAS or an SPI diet before mating, and during pregnancy and lactation. Male offspring from the same litter were pair-fed either a control or ethanol diet for six weeks (CAS/CON, CAS/EtOH, SPI/CON, and SPI/EtOH groups)...

Could the presence of an endometrioma change the management of Assisted Reproductive Technology? The presence of an endometrioma (<6cm) at the time of stimulation or an endometrioma operated prior to stimulation have no impact on the quality of the embryos and the final results of IVF about the pregnancy and live birth rates despite a possible decrease in the number of oocytes retrieved and potentially higher doses of gonadotropins used. The discovery of an endometrioma during IVF stimulation should not lead to an interruption of the attempt...

While the risks of maternal alcohol abuse during pregnancy are well-established, several preclinical studies suggest that chronic preconception alcohol consumption by either parent may also have significance consequences for offspring health and development. Notably, since isogenic male mice used in these studies are not involved in gestation or rearing of offspring, the cross-generational effects of paternal alcohol exposure suggest a germline-based epigenetic mechanism. Many recent studies have demonstrated that the effects of paternal environmental exposures such as stress or malnutrition can be transmitted to the next generation via alterations to small noncoding RNAs in sperm...

Prenatal ethanol exposure is known to cause neurodevelopmental disorders. While high prevalence of epilepsy is observed among the children whose mothers abused alcohol during pregnancy, the results from animal studies are conflicting. Here, we investigated whether embryonic exposure to ethanol can increase the susceptibility to pentylenetetrazole (PTZ)-induced seizures in larval zebrafish. Embryos at 3 hours post-fertilization (hpf) were exposed to ethanol at the concentrations ranging from 0.25% to 1% for 21 hours...

Fetal alcohol spectrum disorder (FASD) is the principal preventable cause of mental retardation in the western countries resulting from alcohol exposure during pregnancy. Ethanol-induced massive neuronal cell death occurs mainly in immature neurons during the brain growth spurt period. The cerebellum is one of the brain areas that are most sensitive to ethanol neurotoxicity. Currently, there is no effective treatment that targets the causes of these disorders and efficient treatments to counteract or reverse FASD are desirable...

Alcohol consumption during pregnancy induces Fetal Alcohol Spectrum Disorder (FASD), which has been proposed to arise from competitive inhibition of retinoic acid (RA) biosynthesis. We provide biochemical and developmental evidence identifying acetaldehyde as responsible for this inhibition. In the embryo, RA production by RALDH2 (ALDH1A2), the main retinaldehyde dehydrogenase expressed at that stage, is inhibited by ethanol exposure. Pharmacological inhibition of the embryonic alcohol dehydrogenase activity, prevents the oxidation of ethanol to acetaldehyde that in turn functions as a RALDH2 inhibitor...

Adverse maternal behaviors during pregnancy and unfavorable postnatal experiences during development are associated with an increased risk of developing psychiatric disorders, as well as, a vulnerability to alcohol addiction in adulthood. Here, we examined the effects of combined ethanol exposure during late pregnancy and postnatal maternal separation (MS) on HPA responsiveness, anxiety behavior and preference for alcohol consumption in adult male rats. Animals exposed to both conditions revealed a decrease in blood levels of allopregnanolone accompanied by increased anxiety behavior...

Fetal alcohol spectrum disorders (FASD) are caused by ethanol exposure during the pregnancy and is the leading cause of mental retardation. Ethanol exposure during the development results in the loss of neurons in the developing brain, which may underlie many neurobehavioral deficits associated with FASD. It is important to understand the mechanisms underlying ethanol-induced neuronal loss and develop appropriate therapeutic strategies. One of the potential mechanisms involves neuroimmune activation. Using a third trimester equivalent mouse model of ethanol exposure, we demonstrated that ethanol induced a wide-spread neuroapoptosis, microglial activation, and neuroinflammation in C57BL/6 mice...

Several disorders in children, called Fetal Alcohol Spectrum Disorders (FASD), occur as result of alcohol consumption during pregnancy and lactation. They appear, at least in part, to be related to the oxidative stress that this drug generates. Ethanol metabolism generates reactive oxygen species and causes a depletion of the antioxidant molecule glutathione (GSH) leading to oxidative stress and lipid and protein damage which are related to growth retardation and neurotoxicity, increasing the incidence of FASD...

Alcohol consumption around the time of conception is highly prevalent in Western countries. Exposure to ethanol levels during gestation has been associated with altered development of the mesolimbic reward pathway in rats and increased propensity to addiction, however the effect of exposure only around the time of conception is unknown. The current study investigated the effects of periconceptional alcohol exposure (PC:EtOH) on alcohol and palatable food preferences and gene expression in the ventral tegmental area (VTA) and the nucleus accumbens of the adult offspring...

AIM: The fetal alcohol exposition during pregnancy leads to different disorders in offspring, related to the oxidative stress generated by alcohol. It is well-documented that there is an impairment of the antioxidant selenoprotein Glutathione peroxidase (GPx) activity in ethanol offspring during the embryo period, although no-one has described Selenium (Se) status. The aim is to analyze for the first time Se deposits in vivo and Se's biological implication in embryos and placenta after alcohol exposure and in offspring whose mothers continued to drink ethanol during lactation...

BACKGROUND: Despite known risks of prenatal nutritional deficiencies and studies documenting increased prevalence of poor dietary intake among nonpregnant alcohol abusers, the nutritional status of heavy drinking pregnant women remains largely unstudied. Animal models have found interactions between prenatal ethanol exposure and micronutrients, such as choline, folate, B12, and iron, and human studies have reported that lower maternal weight and body mass confer increased fetal alcohol-related risk...
