1. High-definition ultrasonography for evaluation of embryonic and fetal development in bitch
RESUMO Em mulheres, a ultrassonografia de alta definição fornece imagens de alta qualidade de tecidos normais e alterados durante a gravidez, entretanto não existem estudos veterinários que descrevam o uso dessa tecnologia em cadelas prenhas. O objetivo deste estudo foi avaliar diariamente cadelas braquicefálicas gestantes, por meio de ultrassonografia

2. [PROVISIONAL] Birth defects in Brazil: Outcomes of a population-based study
Abstract Birth defects (BDs) are functional and structural alterations in embryonic or fetal development. With an incidence of approximately 3-5%, BDs are a leading cause of infant mortality and lifelong disability. A population-based prospective case-control study was conducted for one year with 5204 infants, between 1st March 2011 and 29th February 2012, i

3. Perinatal effects of scorpion venoms: maternal and offspring development
Abstract Scorpion envenomation is a public health problem, especially in tropical and subtropical countries. Considering the high incidence of scorpionism in some areas, pregnant women and nursing mothers may be possible victims. Scorpion stings alter the release of neurotransmitters and some cytokines. These mediators act as organizers and programmers in th

4. BPI-fold (BPIF) containing/plunc protein expression in human fetal major and minor salivary glands
Abstract The aim of this study was to determine expression, not previously described, of PLUNC (palate, lung, and nasal epithelium clone) (BPI-fold containing) proteins in major and minor salivary glands from very early fetal tissue to the end of the second trimester and thus gain further insight into the function of these proteins. Early fetal heads, and ma

5. Effect of oral supplementation of the linoleic and gammalinolenic acids on the diabetic pregnant rats
The aim of this work was to evaluate the direct protective action of oral fatty acid supplementation against the deleterious effect of hyperglycemia on maternal reproductive outcomes; fetal growth and development on female Wistar rats. The animals were distributed into four experimental groups: G1= non-diabetic without supplementation (Control group); G2= no

6. Plasma concentrations and placental immunostaining of interleukin-10 and tumornecrosis factor-α as predictors of alterations in the embryo-fetal organism and the placental development of diabetic rats
Interleukin-10 (IL-10) appears to be the key cytokine for the maintenance of pregnancy and inhibits the secretion of inflammatory cytokines such as tumor necrosis factor-α (TNF-α). However, there are no studies evaluating the profile of these cytokines in diabetic rat models. Thus, our aim was to analyze IL-10 and TNF-α immunostaining in placental tissue

7. Os hormônios tireoideanos e o desenvolvimento esquelético fetal e pós-natal: estudo do padrão de expressão dos transportadores e das selenodesiodases das iodotironinas. / Thyroid hormone and skeletal development at fetal and postnatal ages: the expression pattern of iodothyronine transporters and deiodinases.
Thyroid hormone (TH) plays a key role on post-natal bone development and metabolism, while its relevance during fetal bone development is uncertain. To study this, pregnant mice and fetuses were made hypothyroid. The skeleton morphology was preserved up to 16.5 embryonic days (E). Only at E18.5, the hypothyroid fetuses exhibited a reduction in femoral type I

8. Ovulação e desenvolvimento uterino, placentário e fetal em marrãs gestantes tratadas com tiroxina
The aim of this study was to evaluate the effect of administration of thyroxine on ovulation and fetal and placental, uterine development in gilts at 70 days of gestation. 20 gilts, middle-sisters, and daughters of F1 females with a male, ¾ Landrace X ¼ Large White were used. At 150 days of age, i.e., before first heat, the animals were randomly divided in

9. Desenvolvimento embriológico e fetal em pacas (Agouti paca, Linnaeus 1766): estabelecimento de modelo experimental análogo murino para detecção de linhagens "Germ Cells" / Development of embryonic and fetal of pacas (Agouti paca, Linnaeus 1766): establishment of experimental model analogous to murine "Germ cells" linage detection
The study aimed elucidates the development of embryonic and fetal of pacas (Agouti paca) and demarcation of the germ sites in embryos at different stages. Seven specimens were used; two embryos and three fetuses from UNESP- Jaboticabal and other two fetuses were from FMVZ-USP collection. The fetuses 1 and 2 showed immaturity facial sharp, eyes covered by a l

10. Relationship between the maternal diabetes and the sexual development of the male rat offspring / Relação entre o diabete materno e o desenvolvimento sexual da prole masculina de ratos
Diabetes melllitus is a group of metabolic disorders of multiple etiology, characterized by defects in the secretion and/or action of insulin. The causes of the disease can be genetic and/or environmental. Diabetes is one of the most common metabolic complications during pregnancy and is associated with an increased risk of maternal and neonatal morbidities.

11. Study about the development of renais systems in bovines embryos (Bos indicus and Bos taurus) during the gestation period 10 and 50 days / Estudo do desenvolvimento dos Sistemas Renais de embriões bovinos (Bos indicus e Bos taurus) durante o período gestacional compreendido entre 10 e 50 dias
The present scientific study it has as objective to describe the development of the bovine Renais Systems, during the embryonic period. For in such a way, embryos collected in freezers of the region had been used, and after the collection the same ones had been photographed and measured using the Crow-Rump method (CR). For morphologic description they had be

12. Medidas de indicadores de estresse oxidativo e de remodelamento cardíaco em camundongos expostos à poluição atmosférica ambiental durante o desenvolvimento embrionário e pós-natal / Measurements of oxidative stress indicators and of cardiac remodeling in mice exposed to urban air pollution during embrionary and postnatal development.
I t is well known that air pollution exposure in São Paulo can elicit cardiovascular injuries in humans and experimental animals and that children and fetuses appear to be particularly vulnerable. However, the mechanisms involved in this cardiovascular damage are not well understood. It has been suggested that the oxidative stress generated by air pollution
