1. Causes of misdiagnosis in assessing tubal patency by transvaginal real-time three-dimensional hysterosalpingo-contrast sonography
RESUMO OBJETIVO Este estudo tem como objetivo investigar as causas do diagnóstico equivocado na avaliação da patência tubária por meio da ultrassonografia de contraste histerosalpingo em tempo real transvaginal (TVS RT-3D-HyCoSy), a fim de melhorar a eficiência diagnóstica das TVS RT-3D-HyCoSy. MÉTODOS Um total de 162 ovidutos em 83 pacientes da

2. Morphometric analysis of Littoraria angulifera (Caenogastropoda) in estuarine regions of northeastern Brazil
Resumo O gastrópode Littoraria angulifera (Littorinidae) é um molusco exclusivamente estuarino com distribuição anfiatlântica neotropical. Estudos recentes indicam um possível uso dessa espécie como bioindicadora. No presente estudo teve-se por objetivos analisar a altura da concha, assim como realizar uma análise morfométrica do aparato reprodutor

3. Ovarian Morphology and Egg Quality Traits of Egyptian Selected Strain for Egg Production Compared with Commercial Laying Strains
ABSTRACT An experiment was conducted to evaluate the effect of selection for egg production performance of Cairo L-2 strain, as a local layer strain, after five generations of selection on productivity, ovarian morphology and some egg quality traits versus commercial Lohmann Brown-Lite (LBL) strain. The performance in the 5th generation was evaluated in Cair

4. Effects of Laser Beak Trimming on the Development of Brown Layer Pullets
ABSTRACT Laser beak trimming is a promising alternative to conventional hot-blade beak trimming as it is less painful and provides better beak uniformity and better animal welfare. In this study, laser vs. hot-blade beak trimming were compared in 400 Hy-line Brown pullets between 2-16 weeks of age. At 7 days of age, birds were distributed according to a comp

5. ACTIVIDAD REPRODUCTIVA Y DIETA DE HEMIDACTYLUS FRENATUS (SAURIA: GEKKONIDAE) EN EL NORTE DE COLOMBIA
ABSTRACT Despite its success as an invasive species, little is known about the ecological aspects of the gekkonid lizard Hemidactylus frenatus in Colombia. In the present study the size at maturity, sexual dimorphism, reproductive activity, and diet composition of a population of this species in an urban locality of Northern Colombia were determined. We cond

6. Effect of Led Lighting Colors for Laying Japanese Quails
ABSTRACT Time of exposure and light intensity rearing house may affect the performance and egg quality of laying quails. This research aimed at evaluating the live performance, egg quality, biometry of the reproductive system, and the gastrointestinal tract of Japanese quails (Coturnix coturnix japonica) exposed to artificial light-emitting diodes (LED) of d

7. Expression of Nerve Growth Factor (NGF) and Its Receptors TrkA and p75 in the Reproductive Organs of Laying Hens
Abstract In order to investigate the expression levels of nerve growth factor (NGF) and its receptors (TrkA and p75) in prehierarchical follicles and oviducts of hens, five 130-day-old laying hens were examined by immunohistochemistry and RT-PCR analysis. NGF and its receptors were expressed in theca cells and granulosa cells of prehierarchical follicles, an

8. Effects of Arginine Supplementation on Organ Development, Egg Quality, Serum Biochemical parameters, and Immune Status of Laying Hens
Abstract This experiment was conducted to study the effects of arginine supplementation on organ development, egg quality, blood parameters, and immune status of laying hens. A total of 360 25-week-old brown Leghorn laying hens were randomly divided into three groups with six replicates of 20 birds each and fed diets supplemented with 0, 8.5, or 17 mg of L-a

9. Morphological analysis of the oviduct, oviducal gland and isthmus of the blue shark Prionace glauca (Linnaeus, 1758) (Elasmobranchii: Carcharhiniformes)
RESUMO A glândula oviducal presente nos elasmobrânquios está correlacionada com a estratégia reprodutiva, cuja função é de produzir o muco, formar o envelope terciário do ovo e armazenar espermatozóides. A glândula contém quatro zonas: club, papilar, baffle e terminal. Foi descrita a estrutura do oviduto, glândula oviducal e istmo do tubarão-azu

10. Histological and immunohistochemical study of the ovaries and oviducts of the juvenile female of Caiman latirostris (Crocodilia: Alligatoridae)
ABSTRACT The purpose of this study was to examine the ovaries and the oviduct of juvenile females of the broad-snouted caiman, Caiman latirostris (Daudin, 1802), using light microscopy, histochemical and immunocytochemical techniques. The ovarian cortex was observed to contain groups of germinative cells and abundant previtellogenic follicles at different st

11. Histochemical study of the oviducal gland and analysis of the sperm storage tubules of Mustelus schmitti Springer, 1939 (Chondrichthyes, Triakidae)
Abstract: The paired oviducal glands of immature and mature females of Mustelus schmitti were examined macro and microscopically. Findings indicate that these glands possessed the same zonation as in most chondrichthyans from anterior to posterior: club, papillary, baffle and terminal zones. The whole gland is composed by simple tubular glands that connect w

12. Re-characterization of the Red-lip Megalobulimus (Gastropoda: Strophocheilidae) from Peru with description of a new species
Megalobulimus K. Miller, 1878 is a genus of land snails that includes the largest living snails in the Neotropics. The main goal of this paper was to review all species of Megalobulimus that have a red lip, and which are distributed in Peru. We carried out a detailed description of their shells and soft parts, and conducted a multivariate analysis on their s
