Age‐incidence patterns of seminoma and nonseminoma among males and females in Germany and the United States, 2008–2016

Andrology, Volume 11, Issue 1, Page 65-72, January 2023., 2023
Abstract Background & objectives The comparison of the incidence of gonadal germ cell tumors among males and females can provide insights that cannot be gained by separately studying these tumors. Material and methods Incidence data on male and female gonadal germ cell tumors were drawn from the cancer registries of North Rhine‐Westphalia, Germany, and

Definitive Hematopoiesis in the Yolk Sac Emerges from Wnt‐Responsive Hemogenic Endothelium Independently of Circulation and Arterial Identity

Stem Cells, 2016
Adult‐repopulating hematopoietic stem cells (HSCs) emerge in low numbers in the midgestation mouse embryo from a subset of arterial endothelium, through an endothelial‐to‐hematopoietic transition.

Gluconeogenesis in the Yolk Sac Membrane: Enzyme Activity, Gene Expression, and Metabolites During Layer Chicken Development

The Journal of Poultry Science, 2023
Yolk sac membranes of layer eggs were collected daily (n = 7–9) from day three of incubation to day three post-hatch, and mRNA expression and activities were quantified for key gluconeogenesis enzymes (glucose-6-phosphatase, fructose-1 ...

How to deform an egg yolk? On the Study of Soft Matter Deformation in a Liquid Environment [PDF]

, 2020
In this paper, we report a novel experimental and theoretical study to examine the response of a soft capsule bathed in a liquid environment to sudden external impacts. Taking an egg yolk as an example, we found that the soft matter is not sensitive to translational impacts, but is very sensitive to rotational, especially decelerating-rotational ...

Expression of thyroid hormone regulator genes in the yolk sac membrane of the developing chicken embryo

Journal of reproduction and development, 2017
Thyroid hormones (THs) are essential for the correct development of nearly every structure in the body from the very early stages of development, yet the embryonic thyroid gland is not functional at these stages. To clarify the roles of the egg yolk as a

Cytokeratin 13 (CK13) expression in cancer: a tissue microarray study on 10,439 tumors

APMIS, Volume 131, Issue 2, Page 77-91, February 2023., 2023
Cytokeratin 13 (CK13) is a type I acidic low molecular weight cytokeratin, which is mainly expressed in urothelium and in the squamous epithelium of various sites of origin. Loss of CK13 has been implicated in the development and progression of squamous epithelial neoplasms. To comprehensively determine CK13 expression in normal and neoplastic tissues,

Dynamics of a suspension of interacting yolk-shell particles [PDF]

, 2014
In this work we study the self-diffusion properties of a liquid of hollow spherical particles (shells)bearing a smaller solid sphere in their interior (yolks). We model this system using purely repulsive hard-body interactions between all (shell and yolk) particles, but assume the presence of a background ideal solvent such that all the particles ...

Escape from TGF‐β‐induced senescence promotes aggressive hallmarks in epithelial hepatocellular carcinoma cells

Molecular Oncology, EarlyView.
Chronic TGF‐β exposure drives epithelial HCC cells from a senescent state to a TGF‐β resistant mesenchymal phenotype. This transition is characterized by the loss of Smad3‐mediated signaling, escape from senescence, enhanced invasiveness and metastatic potential, and upregulation of key resistance modulators such as MARK1 and GRM8, ultimately promoting

EFFECT OF EXPERIMENTAL YOLK SAC INFECTION WITH ESCHERICHIA COLI ON IMMUNE STATUS OF BROILER CHICKS [PDF]

Pakistan Veterinary Journal, 2004
In this study, 100 day-old broiler chicks were divided into two groups, A and B containing 50 birds each. Experimental infection with E. coli was given intra yolk to group A on day-1 of experiment, while group B was kept as control.

Target Entropy Annealing for Discrete Soft Actor-Critic [PDF]

neurips 2021 deep rl workshop, 2021
Soft Actor-Critic (SAC) is considered the state-of-the-art algorithm in continuous action space settings. It uses the maximum entropy framework for efficiency and stability, and applies a heuristic temperature Lagrange term to tune the temperature $\alpha$, which determines how "soft" the policy should be.
