During the trunk to tail transition the mammalian embryo builds the outlets for the intestinal and urogenital tracts, lays down the primordia Heartburn for the hindlimb and external genitalia, and switches from the epiblast/primitive streak (PS) to the tail bud as the driver of axial extension.Genetic and molecular data indicate that Tgfbr1 is a ke

The article presents tests on one-year artificially bred Atlantic salmon.For 14 days, fish were exposed to lead nitrate Pb (NO3)2 under concentration corresponding to the highest allowable standard of inland water making 0.005 mg Pb/l.Lead (Pb) in fish tissues (muscle and gills) was determined applying atomic absorption spectrophotometry (AAS).The

Abstract Background Laparoscopic cholecystectomy (LC) for difficult acute cholecystitis (AC) cases bears a high risk of vasculobiliary injuries (VBI).The Tokyo Guidelines 2018 (TG18) recommend the use of bailout procedures and subtotal cholecystectomy to prevent VBI.Performing a safe LC is challenging, even when followed by an accurate pre-surgical

Radiocarbon is a critical constraint on our estimates of the timescales of soil carbon cycling that can aid in identifying mechanisms of carbon stabilization and destabilization and improve the forecast of soil carbon response to management or environmental change.Despite the wealth of soil radiocarbon data that have been reported over the past 75
