Immunophenotypic assessment of pure embryonal carcinoma and yolk sac tumour suggests that reprogramming to non‐seminoma occurs outside the spermatogonial niche

Histopathology, EarlyView.
Immunohistochemical analysis of transcription factors in GCNIS associated with pure EC and YST suggests that reprogramming to non‐seminoma occurs outside the spermatogonial niche. In these tumors, reprogramming may occur immediately upon invasion of the stroma or within seminiferous tubules but outside the spermatogonial niche (i.e., in intratubular ...

Burned-out Metastatic Yolk Sac Tumour: A Rare Case Report

JK Science
Burned-out testicular tumor is a very rare clinical entity. There are no clinical findings in the testicle because it regresses spontaneously without any treatment and generally presents with metastases.

FOXA1 is a highly sensitive diagnostic marker for prostate cancer including small cell carcinoma of the prostate

Histopathology, EarlyView.
FOXA1 is a highly sensitive diagnostic marker for prostate cancer. Besides prostatic adenocarcinoma, it is also expressed in 57%–80% of metastatic or primary prostatic small cell carcinomas, which lose traditional prostatic markers including NKX3.1. Although it is less specific than NKX3.1, it can serve as a valuable adjunct for confirming prostatic ...

Αlpha-fetoprotein Producing Gastric Cancer with Yolk Sac Component: Two Rare Case Reports

Middle East Journal of Cancer, 2016
Alpha-fetoprotein producing gastric cancer accounts for less than 10% of the gastric adenocarcinomas. Different histologic subtypes may exist, the least common of which is yolk sac morphology.

Reproductive parameters of wild and hatchery‐reared sea trout (Salmo trutta m. trutta L.) females from the Łeba River (southern Baltic Sea)

Journal of Fish Biology, EarlyView.
Abstract Sea trout Salmo trutta m. trutta L. has high socioeconomic and ecological importance in the Atlantic region; therefore, stocking hatchery‐reared fish is widely practiced for stock enhancement and recovery of wild populations. In this study, fecundity of wild and stocked hatchery‐reared sea trout sampled from the Łeba River (southern Baltic Sea

Occurrence of multiple congenital anomalies in Potamotrygon amandae (Elasmobranchii, Potamotrygoninae) embryos, including the first report of bicephaly

Journal of Fish Biology, EarlyView.
Abstract Reports of teratogenic embryos in elasmobranchs have been documented in multiple species, with proposed aetiologies including environmental disturbances, genetic mutations, predation, exposure to endocrine‐disrupting compounds and maternal stress.

Assessing local adaptation and divergence at early life stages within Eastern Baltic cod (Gadus morhua)

Journal of Fish Biology, EarlyView.
Abstract Many commercially exploited fish stocks have declined over the last few decades. It is therefore essential to identify natural populations and understand local adaptation for sustainable management. Salinity is a key environmental factor shaping local adaptation, and adaptive trait divergence often occurs at the egg and larval stages.

Temperature effects from hydropeaking impair egg and larval development in Danube salmon Hucho hucho and brown trout Salmo trutta

Journal of Fish Biology, EarlyView.
Abstract Hydropeaking is considered an important stressor for salmonids and other species in rivers affected by hydropower. In this study, we investigated the in situ effects of hydropeaking on the survival of eggs and larvae of fall spawning brown trout as well as spring spawning Danube salmon.
