Seasonal synchronization based on day length (photoperiod) allows organisms to anticipate environmental change. Photoperiodic decoding relies on circadian clocks, but the underlying molecular pathways have remained elusive [1]. In mammals and birds, photoperiodic responses depend crucially on expression of thyrotrophin β subunit RNA (TSHβ) in the pars tuberalis (PT) of the pituitary gland [2-4]...

Use of the dioxin toxic equivalency factor (TEF) approach in human risk assessments assumes that the combined effects of dioxin-like compounds in a mixture can be predicted based on a potency-adjusted dose-additive combination of constituents of the mixture. In this study, we evaluated the TEF approach in experimental 2-year rodent cancer bioassays with female Harlan Sprague-Dawley rats receivi...

BACKGROUND Children with congenital esophageal atresia (EA) and tracheoesophageal fistula (TEF) have chronic respiratory symptoms including recurrent pneumonia, wheezing and persistent cough. The aim of this study is to describe the clinical findings of a large group of children with EA and TEF surgically corrected and the instrumental investigation to which they have undergone in order to bett...

Tef (Eragrostis tef (Zucc.) Trotter) is an annual small grain, panicle bearing, C4 cereal crop native to Ethiopia, where it a major staple food. The objectives of the present study were characterize responses two genotypes escalating phosphorus (P) and potassium (K) levels determine optimum range for P K at which performance maximized. Two experiments carried out in Gilat Research Station, each...

Abstract Background Improved survival of neonates with esophageal atresia with/without tracheoesophageal fistula (EA/TEF) has resulted in increased prevalence gastro-esophageal and respiratory-related morbidities. However, long-term outcome data on these patients remains limited, making it difficult to substantiate any guidelines their chronic care. The purpose our study is report post-operativ...

In the realm of education, feedback from peers and teachers is critical importance. The rapid growth electronic (EF) has led to various innovations in feedback, particularly for teachers’ EF (TEF) context English as a foreign language (EFL). This study contributes literature on by examining how students EFL writing classes were influenced TEF offered synchronously via online class dis...

This paper considers a two-echelon supply chain consisting of supplier and capital-constrained retailer. Both the retailer are risk-averse decision makers. The may adopt two mixed financing modes: (1) bank credit equity (BEF) (2) trade (TEF). Using mean-variance framework, we analyze members ordering decisions in cases: symmetric asymmetric risk aversion threshold information. In case informati...

In the presence of a preparation of purified thymus extract factors (TEF), spleen cells from athymic nude mice develop in vitro immune responses to soluble DNP-protein conjugates, to particulate sheep red blood cells, and to allogeneic cells. TEF has similar effects also on the in vitro antibody responses of normal mouse spleen cells, enhancing antigen-dependent plaque-forming cells responses t...
