To investigate the influence of fat-feeding dams on the food choice of their pups after weaning, each of three groups of dams was fed a low-fat diet (LHD), a high-fat diet (HFD) or a two-choice diet of LFD and HFD during pregnancy and lactation. Immediately after weaning, all pups were placed on a two-choice diet program for 5 wk. The fat energy ratio (F ratio) for dams fed the two-choice diet ...

The building of large dams in the Upper Paraná River basin altered the discharge regime at the Porto São José River section. The discharge regime has been altered since 1972, but the changes intensified after the Porto Primavera damming, in late 1998. Considering that discharge control affects the relationship between channel and floodplain, this work aimed to evaluate the intensity of the disc...

Knowing that maternal diabetes is related to hyperglycemia and fetal hyperinsulinemia, which affect the lipid metabolism, the aim of this study was to evaluate the effects of Malpighia emarginata (acerola) juice on the glycemic and lipid profile of offspring of diabetic and nondiabetic Wistar rats. The adult offspring of non-diabetic dams and of dams with severe streptozotocin-induced diabetes ...

In this cross-sectional questionnaire-based study, we surveyed the attitudes toward, knowledge of, and use of rubber dams (RDs) among dentists in southern Nigeria. The questionnaire, which was distributed and collected by one of the authors, requested information on the dentists' background characteristics, attitudes, and knowledge. Data were analyzed with SPSS, and the chi-square was used to a...

check dams, are small dams in the watershed. these dams are constructed in susceptible areas to erosion due to reduce of flow velocity and erosion, control of sediment and flood in upstream of reservoir dams. these structures are made using wood, stone and cement, and gabion. these structures change the hydrological response of the watershed by reducing flow velocity, the channel slope and stor...

The effects of dietary sialic acid in dams on the learning abilities of their pups after weaning were investigated using rats deficient in n-3 fatty acids. Nine-week-old female Wistar rats were fed an n-3 fatty acid-deficient diet for 3 wk and were mated at 12 wk of age. During pregnancy and lactation, the female rats were fed the n-3 fatty acid-deficient diet, and were given water or water con...

In previous studies of effects of offspring sex on postnatal maternal effort there has often been unintentional confounding of the sex ratio of the pups that a dam reared with the sex ratio of the litter that she gestated. By controlling the sex ratio of litters that female subjects gestated, we showed that (1) the probability of dams retrieving pups was influenced by the sex ratio of the litte...

The coefficient of earth pressure at rest, K0, is a significant mechanical parameter, and the investigation K0 coarse-grained soil has important theoretical significance applicational value in geotechnical engineering. However, there are few studies on influence initial dry density (ρd) due to limitations related test instruments or methods. A series tests for two types soils (rockfill sandy-gr...

Previous research has shown that parity (P) 4 progeny have greater weaning weights and decreased microbial diversity. The objective of this experiment was to evaluate litter performance, passive immunity, and fecal microbiota among P1 (n = 56) and P3 (n = 49) dams and their progeny. Blood samples were collected from P1 and P3 dams on d 90 and 114 of gestation and d 0 of lactation and from their...
