Gonadal development of Peprilus medius (Peters, 1869) (Perciformes: Stromateidae) from Southeast of the Gulf of California, Mexico

Int. j. morphol; 35 (1), 2017
The gonadal development assessment is a fundamental work in researching the reproduction of Peprilus medius, on the way to understand its population dynamics and to achieve a sustainable management of its fisheries. The diagnosis based on morphochromatic features is the quicker, more practical and cheape...

Phytotherapy in reducing glycemic index and testicular oxidative stress resulting from induced diabetes: a review

Braz. j. biol; 77 (1), 2017
Abstract Oxidative stress plays a main role in the development of diabetes complications. The impairment of gonadal antioxidant potential and endocrine disturbance in diabetic males causes testicular damage and failure in sperm production. Plants have been widely used to control diabetes due their hypogl...

Short-term buserelin administration induces apoptosis and morphological changes in adult rat testes

Acta cir. bras; 32 (2), 2017
Abstract Purpose: To investigate the effect of buserelin on gonadal structure and function in adult male rats. Methods: Twenty-four adult Wistar male rats were divided into three groups: two treated groups and controls. The first and second treated groups received 300 (low dose) and 500 (high dose) µ...

Musk gland seasonal development and musk secretion are regulated by the testis in muskrat (Ondatra zibethicus)

Biol. Res; 50 (), 2017
BACKGROUND: The muskrat is a seasonal breeder. Males secrete musk to attract females during the breeding season. The testosterone binding to the androgen receptor (AR) in musk glands of muskrat may play an important role conducting the musk secretion process. METHODS: The musk gland, testis and blood sam...

Immunohistochemical study of aquaporin 1 and 2 in the reproductive tract of the bactrian camel (Camelus bactrianus)

Int. j. morphol; 34 (4), 2016
Spermatogenesis is associated with considerable fluid secretion or absorption in the male reproductive tract. Aquaporins (AQPs) are membrane protein channels that allow the rapid movement of water through epithelium. In the present study, immunohistochemistry was utilized to localize the expression of AQ...

Permanent germinal epithelium and reproductive cycle of Atractosteus tropicus (Lepisosteiformes: Lepisosteidae) males, Tabasco, Mexico

Rev. biol. trop; 64 (4), 2016
Abstract:The tropical gar A. tropicus plays an important ecological role as it regulates other fish stocks in different water bodies in Southeastern México. Nevertheless, wild populations are declining, and one conservation alternative is the aquaculture production and basic knowledge of reproductive bi...

The amount of spermatic cord rotation magnifies the time-related orchidectomy risk in Intravaginal testicular torsion

Int. braz. j. urol; 42 (6), 2016
Abstract Purpose To investigate the roles of age, testicular rotation and time in the surgical outcome of intravaginal testicular torsion (iTT). Patients and Methods We retrieved the records of all iTT patients treated in our unit from January 2012 to January 2014. Explanatory variables were: age (year...

Expression analysis of vasa in Asian paddle crab (Charybdis japónica) exposed to Bisphenol A

Electron. j. biotechnol; 19 (6), 2016
Background: Bisphenol A (BPA) is an endocrine-disrupting chemical (EDC) with a weak estrogen-like activity in fish that is found ubiquitously in aquatic environments. However, there has been little study about BPA on the endocrine disrupting effects of crab. In the present study, cDNA of vasa was cloned ...

Cocaine abuse that presents with acute scrotal pain and mimics testicular torsion

Int. braz. j. urol; 42 (5), 2016
ABSTRACT Report case (s) relevant aspects: Man, 27 years old, complaining of acute testicular pain by 2 hours in the remaining left testicle. Denies fever, lower urinary tract symptoms such as dysuria, urinary frequency, concommitant or prior urethral discharge to the painful condition. He underwent righ...
