1. Biometry and ultrasound evaluation of testicles and accessory glands in Santa Ines rams
ABSTRACT This work aimed to investigate the relationship between echogenicity, testicular biometry, and accessory gland biometry and evaluate the echogenicity pattern of these structures in Santa Ines rams. Fifty-four healthy Santa Ines sheep were classified into three age groups: group 1 - 3 to 5 months (pre-pubertal); group 2 - 7 to 11 months (pubertal); a

2. A Histological Study on Venom Apparatus of Montivipera xanthina (Gray, 1849) (Serpentes, Viperidae)
ABSTRACT This is the first report describing morphological and histological structure of venom apparatus in Montivipera xanthina. The venom gland apparatus of M. xanthina was composed of four distinct parts, main venom gland, primary duct, accessory gland and secondary duct. The main venom gland was composed of acini. The accessory gland was formed by long a

3. Male accessory gland substances from Aedes albopictus affect the locomotor activity of Aedes aegypti females
Dengue is one of the world’s most important mosquito-borne diseases and is usually transmitted by one of two vector species: Aedes aegypti or Aedes albopictus . These two diurnal mosquitoes are frequently found coexisting in similar habitats, enabling interactions between adults, such as cross-mating. The objective of this study was to assess cross-mating

4. Glândula acessória e ducto primário de serpente Bothrops jararaca durante o ciclo de produção de veneno: um estudo morfológico. / Acessory gland and primary duct of the Bothrops jararaca snake during the venom production cycle: a morphological study.
The accessory gland (AG) and the primary duct (PD) are components of the venom gland apparatus of Bothrops jararaca snake. There are few studies about AG and PD and there is still controversy on whether the secretions released by these regions can modify the total venom. Our results show that AG presents simple secretory epithelium with mucous secretory cell

5. Impact of infection on the secretory capacity of the male accessory glands
INTRODUCTION: Studies that compare the impact of different infectious entities of the male reproductive tract (MRT) on the male accessory gland function are controversial. MATERIAL AND METHODS: Semen analyses of 71 patients with proven infections of the MRT were compared with the results of 40 healthy non-infected volunteers. Patients were divided into 3 gro

6. Perfis das distroglicanas e morfo-fisiologia do lobo ventral da prostata de camundongos distroficos / Dystroglycans and laminin BETA 3 features on the prostate of mdx mice
The prostate is a fundamental accessory sex gland for the male reproductive process and the stroma-epithelium interaction has an important role in prostate structural maintenance and function. The basal membrane is an interaction link, offering mechanical and physiological support. Nowadays, different studies suggest that dystroglycan (DG), which is an adhes

7. Estrutura e ultra-estrutura das glândulas salivares de Cimex hemipterus (Fabricius, 1803) (Hemiptera: Cimicidae) / Structure and ultrastructure of the salivary glands of Cimex hemipterus (Fabricius, 1803) (Hemiptera: Cimicidae)
Cimex hemipterus is a hematophagous insect that can be an experimental host of the Trypanosoma cruzi and may play a role as vector of Chagas disease. This work analyzed the structure of the salivary glands of C. hemipterus. Adults were dissected and the salivary glands were analyzed in light microscopy and transmission electron microscopy. The secretory port

8. Morphology of male reproductive system and aspects of the reproductive behavior of Trypoxylon (Trypargilum) (Hymenoptera: Crabronidae) / Morfologia do sistema reprodutor masculino e aspectos do comportamento reprodutivo de Trypoxylon (Trypargilum) (Hymenoptera: Crabronidae)
Male reproductive tract of Trypoxylon (Trypargilum) has the basic pattern of Hymenoptera, with morphological variations that characterize the subgenus. It is formed by a pair of testicles, two deferent ducts and one ejaculatory duct. In each deferent duct there is an enlarged region, the seminal vesicle, with an accessory gland opening in the end of it. Each

9. Drosophila female sexual behavior induced by sterile males showing copulation complementation
Females of most animal species are usually inseminated by more than one male, which allows sperm from different males to compete for fertilization. To prevent invasion of sperm from other males, Drosophila males elicit a rejection behavior in their mates after copulation. Using paired mutant males that, for the lack of accessory glands, are sterile, we show

10. Evolutionary EST analysis identifies rapidly evolving male reproductive proteins in Drosophila
Sequence comparisons of genomes or expressed sequence tags (ESTs) from related organisms provide insight into functional conservation and diversification. We compare the sequences of ESTs from the male accessory gland of Drosophila simulans to their orthologs in its close relative Drosophila melanogaster, and demonstrate rapid divergence of many of these rep

11. Cyst of accessory lacrimal gland.
We present a case of an epithelial cyst of the conjunctiva caused by the dilatation of an accessory lacrimal gland. The case is peculiar in regard to the size of the cyst and the absence of traumatic or inflammatory factors to explain the retention of fluid.

12. Probing the function of Drosophila melanogaster accessory glands by directed cell ablation.
The female Drosophila melanogaster fly undergoes behavioral changes after mating, including an increase in egg laying and an avoidance of remating. Accessory-gland products elicit these changes transiently when introduced into unmated female flies. We report here the generation and phenotype of flies that lack functional accessory-gland main cells as a conse
