Zebrafish xenograft models as a fast platform for metastasis diagnosis and cisplatin response of head and neck squamous cell carcinoma

Animal Models and Experimental Medicine, EarlyView.
A zebrafish xenograft model accurately distinguishes metastatic from non‐metastatic HNSCC and recapitulates cisplatin sensitivity/resistance patterns. Using patient‐derived tumors, it predicts individual therapeutic responses, offering a rapid, clinically applicable platform for guiding personalized treatment. Abstract Background Head and neck squamous

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.

Unveiling the Potential of Metal and Non‐Metal Modified Porous Carbon for the Electrochemical Reduction of CO2

Carbon Energy, EarlyView.
Earth‐abundant metal‐ and non‐metal‐modified porous carbons offer a highly tunable platform for electrochemical CO2 reduction. This review shows how electronic interactions, active‐site coordination, pore architecture, and cooperative catalytic effects jointly govern intermediate stabilization, product selectivity, and device‐relevant CO2RR performance.

Yolk sac tumor of the vagina

Saudi Medical Journal, 2007
Malignant germ-cell tumors GCT are rare tumors of childhood accounting for less than 3% of pediatric malignancies. Endodermal sinus tumors EST form the most common histologic subtype of malignant GCT. The vagina is an extremely rare site for GCTs. An 8-month-old female was admitted with a short history of vaginal bleeding, and a mass protruding from ...

Mosaic activation of the zebrafish hsp70l heat shock promoter: Implications for interpreting transgenes

Developmental Dynamics, EarlyView.
Abstract Background The promoters and enhancers of heat shock genes, such as the 1.5‐kb promoter of the zebrafish hsp70l gene, are valuable tools for temporal activation of transgenes. It has been widely purported that heat shock treatments result in ubiquitous expression of hsp70l‐driven transgenes.

Morphology of the avian yolk sac [PDF]

Journal of Morphology, 2020
Abstract The avian yolk sac is a multifunctional extraembryonic organ that serves not only as a site of nutrient (yolk) absorption, but also for early hemopoiesis, and formation of blood vessels. Although the yolk sac membrane being specialized to function as an extraembryonic absorptive organ, it is neither morphologically nor ...
