A new species of Lonchidiidae (Hybodontiformes) from the Late Jurassic of Brazil (Aliança Formation, Jatobá Basin)

open access: yesThe Anatomical Record, EarlyView.
Abstract The Aliança Formation (Jatobá Basin) represents lacustrine deposits formed in oxygenated waters that hosted a diverse fauna, including Hybodontiform sharks. Within this group, the Family Lonchidiidae comprises 11 valid genera, with Parvodus previously reported in Brazilian deposits from the Brejo Santo Formation (Araripe Basin, Late Jurassic ...

Isotopic Study on Saline Lakes in Antarctica

open access: yesAntarctic Record, 1977
In order to understand the origin of saline lakes in the southern Victoria Land, Soya Coast, and Vestfold Hills, the hydrogen and oxygen isotopic ratios of lake waters were measured. The relationship between the two isotopic ratios in these lakes shifted

Distribution of aquatic mosses in the Soya Coast region, East Antarctica [PDF]

open access: yes, 2003
The distribution of aquatic mosses among 73 lakes in the Soya Coast region, East Antarctica, was surveyed. Two species of mosses, Bryum pseudotriquetrum and Leptobryum sp. were found at the bottom of lakes. B. pseudotriquetrum was found in 38 lakes (52.1%

Patterns in fish assemblages in the Loire floodplain: the role of hydrological connectivity and implications for conservation [PDF]

open access: yes, 2007
Hydrological connectivity is known to determine biodiversity patterns across large river floodplains, but it is often greatly altered by human activities.

Use of Restricted Nursing and a Bovine Appeasing Substance on the Welfare, Growth Performance, and Response to Vaccination of Beef Calves at Weaning

open access: yesAnimal Research and One Health, EarlyView.
The effects of restricted nursing (RN) and the administration of a bovine appeasing substance (BAS) on days −8 and 0 in relation to weaning were evaluated. Both strategies were effective in improving the growth performance of beef calves. Regarding welfare, BAS ‐especially on day 0‐ was more effective than RN.

Geochemical Study of the Formation Process for the Saline Lakes in the Dry Valleys, South Victoria Land, Antarctica

open access: yesAntarctic Record, 1977
A simple model is proposed for the present chemical composition of the saline lakes in the Dry Valleys. A diluted water of sea salt whose compositional ratio was that of sea water was concentrated by evaporation to the present chlorinity.

Hydrogel Embedding of Mesenchymal Stem Cells Supports Extracellular Vesicle Production

open access: yesBiotechnology and Bioengineering, EarlyView.
This study investigates the effects of 3D culture conditions on extracellular vesicle (EV) production by mesenchymal stem cells (MSCs) in a gelatin‐based hydrogel matrix (GelMA). The EVs from both conditions were found to have similar morphological, molecular, and functional properties, but 3D cultures produced more total EVs per volume.

Limnology and plankton diversity of salt lakes from Transylvanian Basin (Romania): A review

open access: yesJournal of Limnology, 2017
In the present work, we review the current knowledge on genesis, limnology and biodiversity of salt lakes distributed around the inner contour of Eastern Carpathian arc (Transylvanian Basin, Central Romania).
