Linfoma de células T/NK primario de testículo. Caso clínico y revisión de la literatura

Rev. méd. Chile; 151 (3), 2023
Natural killer/T cell lymphomas chiefly involving the midline facial structures including the nasal cavity or nasopharyns are a relatively rare type of non-Hodgkin's lymphoma. Apart from the upper respiratory tract, the disease occasionally presents in certain extranodal sites, such as the central nervou...

Gonadal characterization of the Amazonian fish Serrapinnus kriegi (Characidae: Cheirodontinae)

Braz. j. biol; 83 (), 2023
Abstract The knowledge of the testicular and ovarian morphology of a particular fish species is of paramount importance. Such analyze enables the development of studies and techniques aiming the improvement of their reproduction, management, commercialization and even their conservation. This study perfo...

The effectiveness of insulin therapy in the functional and morphological recovery of leydig cells in rats submitted to Diabetes mellitus

Biosci. j. (Online); 39 (), 2023
The effects of systemic insulin administration at different concentrations on the testicular tissue of diabetic adult rats, induced by streptozotocin, are evaluated by the morphological analysis of spermatogenic process. Twenty-four adult male rats were divided into 1) Control Group: they received citrat...

The probable radioprotective role of Acacia nilotica L. against biochemical and cytogenetic disorders induced in gamma irradiated male rats

Biosci. j. (Online); 39 (), 2023
Gum Arabic (Acacia nilotica L.) is a respected plant that has many nutrients and curative practices. It hinders, improves, or manages many disorders. The radio-protective activity of Acacia nilotica was investigated against γ-rays-induced testicle damage in rats. Twenty-four rats were correspondingly di...

Ubiquitin protein E3 ligase ASB9 suppresses proliferation and promotes apoptosis in human spermatogonial stem cell line by inducing HIF1AN degradation

Biol. Res; 56 (), 2023
BACKGROUND: Spermatogonial stem cells (SSCs) are critical for sustaining spermatogenesis. Even though several regulators of SSC have been identified in rodents, the regulatory mechanism of SSC in humans has yet to be discovered. METHODS: To explore the regulatory mechanisms of human SSCs, we analyzed pub...

Cisplatin-induced azoospermia and testicular damage ameliorated by adipose-derived mesenchymal stem cells

Biol. Res; 56 (), 2023
BACKGROUND: The testes are highly susceptible to the adverse effects of chemotherapy and radiation at all stages of life. Exposure to these threats mainly occurs during cancer treatment and as an occupational hazard in radiation centers. The present study investigated the regenerative ability of adipose-...

Cyperus esculentus L. protects testis and sperm morphology of hyperglycaemic rats

Cyperus esculentus L. (tiger nut) is a tuberous plant that promotes and protects reproductive functions, which are usually hampered in diabetics. The present study investigated the effect of Cyperus esculentus tuber extract (CETE) on testicular histology and sperm viability of all...

Expression of the homeobox proteins Dlx-5 and TLX1 during the development of cat testis

Int. j. morphol; 40 (3), 2022
SUMMARY: Recent studies have shown that homeobox proteins play an important role in the formation and development of tissues and organs in the embryonic period. In our study, the distribution of Dlx-5 and TLX proteins, which are members of the homeobox family, in the testis, epididymis and ductus deferen...

Epididymal disjunction anomalies in undescended testis - a factor associated with spermatic obstruction

Int. braz. j. urol; 48 (2), 2022
ABSTRACT Background: To analyze the incidence of epididymal anomalies (EAs) associated to spermatic obstruction in patients with undescended testis (UT) according to testicular position and age. Materials and Methods: We studied 87 patients (110 testis) with cryptorchidism and analyzed the presence of ...
