13. REDESCRIPCIÓN DE POTAMOLITHUS SUPERSULCATUS PILSBRY, 1896 (GASTROPODA, TATEIDAE) DEL SUR DE LA CUENCA DEL PLATA
ABSTRACT The genus Potamolithus Pilsbry, 1896 (Gastropoda; Tateidae), has 31 species, 22 of which are distributed in Argentina in Del Plata basin, defining the Uruguay River and the Río de la Plata as a “hotspot” of diversity in freshwater gastropods. However, most of its species has been described only by conchology characters and a few has anatomical

14. Interactions between prolactin and kisspeptin to control reproduction
ABSTRACT Prolactin is best known for its effects of stimulating mammary gland development and lactogenesis. However, prolactin is a pleiotropic hormone that is able to affect several physiological functions, including fertility. Prolactin receptors (PRLRs) are widely expressed in several tissues, including several brain regions and reproductive tract organs.

15. The structural studies on the medicinal plant Haplophyllum telephioides
ABSTRACT Haplophyllum telephioides Boiss., Rutaceae, is an endemic herb which generally grows at the steppe region in Central Turkey. Its aerial parts in flowering stage are used by local people against influenza virus due to its antimicrobial effect. The main purpose of this study was to examine the morphology, anatomy and histology of the vegetative and re

16. A Synopsis of Sloanea (Elaeocarpaceae) in the Neotropical extra-Amazonian Region
ABSTRACT The genus Sloanea is comprised of 150 species, of which about 50 occur in Brazil among several vegetation types but mainly the Amazon and Atlantic forests. The present work provides a synopsis of the Neotropical species of Sloanea in the extra-Amazonian region based on a recent revision of the genus. In general, morphologically Sloanea comprises lar

17. The reproductive biology of the early-divergent genus Anaxagorea (Annonaceae), and its significance for the evolutionary development of the family
ABSTRACT Data of six studied Neotropical Anaxagorea species are analyzed and discussed with respect to the population structure, flowering phenology, flower morphology, anthesis, scent emission, thermogenesis, floral visitors, breeding system, fruit-set and seed dispersal. The probably reason for the patchy distribution of small populations of Anaxagorea spe

18. 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

19. Recovery of Salmonella Gallinarum in the Organs of Experimentally-Inoculated Japanese Quails (Coturnix coturnix)
ABSTRACTSalmonellosis is an infection caused by specific or non specific serotypes of theSalmonella genus, responsible for losses in the poultry industry. Fowl typhoid, caused by S. Gallinarum (SG) is important because it causes elevated mortality in adult birds, leading to economic losses in the poultry industry. This study aimed at quantifying the number o

20. Intrauterine sexual differentiation: biosyntesis and action of sexual steroid hormones
The objective of this review was to describe sexual differentiation events in mammals, relating them to biosynthesis of sexual steroid hormones and their mechanisms of action. Cholesterol is the precursor of sexual steroid hormone biosynthesis via action of several enzymes converting these hormones. Progestagens hormones serve as substrate for the production

21. Effects of the oral treatment with Copaifera multijuga oil on reproductive performance of male Wistar rats
Copaiba oil, extracted from Copaifera multijuga Hayne, Fabaceae, is widely used for medicinal purposes, especially to treat inflammatory processes. However, there is no report regarding its effect on reproductive performance after used in repeated doses orally. The present study evaluated the effects of the oral administration of Copaiba oil (at doses of 200

22. Systemic and reproductive toxicity induced by Parkia platycephala ethanolic extract in female Wistar rats
The present study was conducted to evaluate the toxicity of the ethanolic extract of leaves of Parkia platycephala Benth., Fabaceae, on systemic and reproductive parameters. In toxicity on the estrous cycle, four groups of not-pregnant Wistar rats received distilled water and the doses 250, 500 and 1000 mg.kg-1 of plant extract for thirty days, at the end of

23. Avaliação do potencial tóxico do extrato hidroalcoólico de Pradosia huberi Ducke sobre o sistema reprodutor masculino e órgãos vitais de ratos e sua prole / Avaliação do potencial tóxico do extrato hidroalcoólico de Pradosia huberi Ducke sobre o sistema reprodutor masculino e órgãos vitais de ratos e sua prole / Evaluation of the toxic potential of hydroalcoholic extract of Pradosia huberi Ducke on the male reproductive system and vital organs of rats and their offspring / Evaluation of the toxic potential of hydroalcoholic extract of Pradosia huberi Ducke on the male reproductive system and vital organs of rats and their offspring
Desde a antiguidade as plantas são utilizadas com fins medicinais para o tratamento, cura e prevenção de doenças. Pradosia huberi Ducke (Sapotaceae) é uma planta medicinal comumente usada pelas comunidades amazônicas por suas atividades gastroprotetora e antiulcerogênica. Considerando-se o uso popular dessa espécie e a presença de compostos bioativo

24. Morfofisiologia do sistema genital masculino de ratos púberes e adultos após privação androgênica durante a pré-puberdade / Morphophysiology of male reproductive system of adult and pubertal rats after androgen deprivation during prepuberty
Endocrine disrupters are chemicals that can act as agonists or antagonists of endogenous hormones, interfering with the homeostasis of the organism. Since the endocrine system plays a critical role in the development and function of the male reproductive system, this is an especially vulnerable target of potential endocrine perturbations. The literature pres
