Iflaviruses in arthropods: when small is mighty

open access: yesInsect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

The Corn Snake Yolk Sac Becomes a Solid Tissue Filled With Blood Vessels and Yolk-Rich Endodermal Cells

open access: yes, 2014
The amniote egg was a key innovation in vertebrate evolution because it supports an independent existence in terrestrial environments. The egg is provisioned with yolk, and development depends on the yolk sac for the mobilization of nutrients.

Comparative Molecular Insights into Developmental and Behavioral Toxicity Induced by Octocrylene and Ethylhexyl Salicylate Exposure on Zebrafish

open access: yesIntegrative Zoology, EarlyView.
This study compared the ecological toxicity of organic ultraviolet filters, octocrylene (OC) and ethylhexyl salicylate (EHS), on zebrafish embryos and larvae. EHS exhibited higher acute toxicity, causing increased mortality, hypoactive behavior at 50 mg/L, and disruptions in lipid homeostasis, while OC primarily affected hypoxia response and ...

Yolk Sac Tumor of the Thyroid Gland: A Case Report

open access: yes, 2011
Extragonadal yolk sac tumors are uncommon and usually seen in sacrococcygeal, mediastinal, intracranial, and retroperitoneal sites. Yolk sac tumors of the head and neck region are rare, and the few reported cases have arisen in neonates or infants in ...

BRD9 inhibition as potential treatment option for testicular germ cell tumors

open access: yesAndrology, EarlyView.
Abstract Background Testicular germ cell tumors (TGCT) are the predominant tumor in younger males. Usually, 5‐year survival rates are quite high, but 15–20% of patients with metastatic non‐seminomas are resistant to standard cisplatin‐based therapy.

Yolk sac development in lizards (Lacertilia: Scincidae): New perspectives on the egg of amniotes

open access: yes, 2017
Embryos of oviparous reptiles develop on the surface of a large mass of yolk, which they metabolize to become relatively large hatchlings. Access to the yolk is provided by tissues growing outward from the embryo to cover the surface of the yolk.

Inhibition of HMGA2 Leads to Reduced Cell Proliferation and Increased Apoptosis in Human Embryonal Carcinoma Cell Lines

open access: yesAndrology, EarlyView.
ABSTRACT Background The most prevalent solid tumors in young men are testicular germ cell tumors (TGCTs), and embryonal carcinoma is the most common subtype among non‐seminomatous germ cell tumors (NSGCTs). Despite the excellent cure rates of cisplatin‐based chemotherapy, resistance develops in 15%–30% of patients with metastatic cancer, which results ...

A Unified Machine Learning Model for Relapse Prediction in Clinical Stage I Testicular Cancer

open access: yesAndrology, EarlyView.
ABSTRACT Background Approximately one‐fourth of patients with clinical stage I testicular cancer relapse. For decades, risk stratification has been based on different tumor characteristics for seminomas and non‐seminomas. Previous studies primarily used Cox proportional‐hazards models and included only a limited number of variables.

Association between abnormal Yolk Sac Appearance and early spontaneous Abortion. A Cohort study.

open access: yes, 2020
  The yolk sac is essential in early life of the embryo because the yolk sac is the first route of exchange between the embryo and the mother.   OBJECTIVE: To determine the association of the spontaneous abortion with the abnormal morphology ...

T Cell Microenvironmental Impacts and Therapeutic Opportunities: Application to Human Testicular Germ Cell Tumors

open access: yesAndrology, EarlyView.
ABSTRACT Testicular germ cell tumors (TGCT) are the leading malignancy in adolescent and young adult males, yet the immunological and cellular mechanisms governing their tumor microenvironment (TME) remain poorly understood. Here, we present a comprehensive review of TGCT pathobiology with a focus on the immune landscape, particularly the role of tumor‐
