Supporting Integrated and Comprehensive Approaches to Climate Change Adaptation in Africa [PDF]

open access: yes, 2010
The Africa Adaptation Programme (AAP) has been designed to support the long-term efforts of targeted countries to further develop their capability to successfully identify, design and implement holistic adaptation and disaster risk reduction programmes ...

Glaciers and Ice Sheets As Analog Environments of Potentially Habitable Icy Worlds

open access: yesFrontiers in Microbiology, 2017
Icy worlds in the solar system and beyond have attracted a remarkable attention as possible habitats for life. The current consideration about whether life exists beyond Earth is based on our knowledge of life in terrestrial cold environments.

Type I interferons modulate autophagy to shape gemcitabine response in pancreatic cancer cells

open access: yesFEBS Open Bio, EarlyView.
Type I interferons differentially modulate autophagy and the response of pancreatic cancer cells to gemcitabine. IFNα2b stimulates autophagic flux and protects cells from gemcitabine‐induced cell death, contributing to chemoresistance. In contrast, IFNβ1a inhibits autophagosome formation and enhances gemcitabine‐induced cell death, resulting in ...

Supporting methods and results from Cold-adaptation increases rates of nutrient flow and metabolic plasticity during cold exposure in Drosophila melanogaster

open access: yes, 2016
Metabolic flexibility is an important component of adaptation to stressful environments, including thermal stress and latitudinal adaptation. A long history of population genetic studies suggest that selection on core metabolic enzymes may shape life ...

The nature of human adaptation to cold

open access: yes, 2002
Human adaptation to repeated short term exposure to cold appears to be characterised by a decreased shivering threshold and unchanged sweating threshold, producing a widening of the inter-threshold zone (1).

ERECTA genes and their ligands regulate shoot and inflorescence architecture in maize

open access: yesNature Communications
In maize, several yield-related traits are associated with meristem activity, regulated by CLAVATA3/EMBRYO SURROUNDING REGION-related (CLE) peptide signals perceived by CLAVATA(CLV) receptors in the CLAVATA-WUSCHEL (CLV-WUS) pathway.

Plant adaptation to cold climates [PDF]

open access: yesF1000Research, 2016
In this short review, I will first summarize criteria by which environments can be considered “cold”, with plant stature (size, height above ground) playing a central role for the climate actually experienced. Plants adapted to such environments have to cope with both extremes and with gradual influences of low temperature.

In vitro generation of regulatory T cells: A challenging tool for studying immune aging in humans

open access: yesFEBS Open Bio, EarlyView.
In vitro induction of human regulatory T cells using standard protocols generates suppressive, Foxp3‐expressing CD4+ T cells independently of TGF‐β supplementation and donor age. Regulatory T (Treg) cells play a key role in immune tolerance and homeostasis.

The Effects of Cold Adaptation on the Growth and Development of the Neandertal Cranial Base [PDF]

open access: yes, 2014
Neandertals and modern humans possess very different craniofacial shapes. Some recent work has attributed these contrasting shapes specifically to differences in brain development, which are extrapolated to mean differences in cognitive function. However,

Dactolisib outperforms Rapamycin in potentiating apoptosis induced by XPO1, Bcl‐2 and Mcl‐1 blockade in preclinical glioblastoma models

open access: yesFEBS Open Bio, EarlyView.
The PAM pathway and its impact on cellular metabolism. Color‐coded key symbols represent Rapamycin (R, orange, targeting mTOR) and Dactolisib (D, green, targeting PI3K/mTOR), indicating their sites of action. Created with BioRenders.com. Glioblastoma resists therapy through interconnected survival programs.
