Paternal behavior and testosterone plasma levels in the Volcano Mouse Neotomodon alstoni (Rodentia: Muridae). Although initially it was thought that inhibited display of paternal males rodents, has been shown some species high are needed for exhibition care. In captivity, (Neotomodon alstoni) provide pups same care provided by mother, with exception suckling. Here we measured plasmatic concentrations 10 days after mating, five 20 postpartum, were isolated from their families order to...
In view of the relationship between shifts in diet composition and activity digestive enzymes penaeid shrimp, present study focused on analysis trypsin |$\alpha$|-amylase activities wild Farfantepenaeus duorarum (Burkenroad, 1939) juveniles their changes phenotypic expression, during molt cycle as endogenous factor due to different feeding regimes (exogenous factor) relation with |${\delta ^{13}}{\rm{C}}$| ^{15}}{\rm{N}}$| isotopic signature an index food assimilation induced by seasonal...
Paternal behavior of the volcano mouse (Neotomodon alstoni) was studied and its role in care young compared with that female. this rodent under laboratory conditions consisted direct indirect activities, such as huddling, grooming, sniffing, retrieving well maintenance vigilance nest. The male exhibited all components parental displayed by mothers, except suckling. However, participated significantly more than female sniffing. existence paternal suggests natural species exhibits a monogamous...
Captive male Neotomodon alstoni exhibit paternal care. We tested whether presence of the in nest during postpartum and weaning periods affect maternal care promoted survival growth offspring. For captive N. pairs (n = 10) both parents were maintained until young, another 10 was removed shortly after birth young. The had a negative impact on time spent by females huddling with nursing In male, groomed sniffed young less frequently than did rearing absence male. Survival offspring (84%) their...
The structural and ultrastructural features of gonads from endemic Mexican fish have received scarce attention. This study describes the histological characteristics oocyte Chirostoma humboldtianum. ovary is asynchronic, as such, most phases development are found in same ovary. complete process oogenesis was divided five stages: oogonium folliculogenesis, primary growth, cortical alveoli lipid inclusions, vitellogenesis, maturation. presence big filaments, which appear at end induces some...
Larrea tridentata (Sesse and Moc. ex DC.) Coville is used for the treatment of gallstones in traditional Mexican medicine. The possible prevention or elimination by ethanolic aqueous extracts leaves twigs L. was tested hamsters fed a rich carbohydrate, fat-free diet. In addition, effects extract its main metabolite, nordihydroguaiaretic acid, on bile secretion perfused liver were tested. experiment gallstones, dry at level 0.5% diet completely inhibited gallstone formation, lowered biliary...
In Oaxaca, México, Haplophyton cimicidum is used in combination with other plants as part of a folk strategy against arthropod pests crops and cattle. Methanolic crude alkaloid (acid–base extraction) extracts H. leaves were analysed by thin-layer chromatography (TLC) assayed vitro for acetylcholinesterase (AChE) inhibitory activity using Spodoptera frugiperda homogenates source enzyme. Derivatised chromatographic plates indicated the presence indoles alkaloids extracts. The extract exhibited...
Background: nutritional anemia caused by iron (Fe) deficiency is considered a major public health problem. Interventions to address have been traditionally focused on supplementation with ionic Fe that causes gastrointestinal adverse effects. On the other hand, some studies demonstrated advantages of both, protein and heme hydrolyzate Fe. However there are few experimental clinical evidences conclude efficacy this strategy treat anemia. Aim: know about physiological biochemical events...
