Cold hardiness and overwintering survival of the grain aphid Sitobion avenae in Northern England [PDF]

open access: yes, 1987
Laboratory maintained Sitobion avenae of all developmental stages had a mean inherent supercooling ability below -20°C. Acclimation alone, or in conjunction with starvation had no significant effect on supercooling.

An experimental exposure study revealing composite airway effects of physical exercise in a subzero environment

open access: yesInternational Journal of Circumpolar Health, 2021
Exposure to a cold climate is associated with an increased morbidity and mortality, but the specific mechanisms are largely unknown. People with cardiopulmonary disease and winter endurance athletes are particularly vulnerable.

Enhanced levels of cold shock proteins in Listeria monocytogenes LO28 upon exposure to low temperature and high hydrostatic pressure [PDF]

open access: yes, 2002
Listeria monocytogenes is a psychrotrophic food-borne pathogen that is problematic for the food industry because of its ubiquitous distribution in nature and its ability to grow at low temperatures and in the presence of high salt concentrations.

Clarifying life lost due to cold and heat: a new approach using annual time series. [PDF]

open access: yes, 2015
OBJECTIVE: To clarify whether deaths associated with hot and cold days are among the frail who would have died anyway in the next few weeks or months. DESIGN: Time series regression analysis of annual deaths in relation to annual summaries of cold and ...

Proteomic Analysis of Listeria monocytogenes FBUNT During Biofilm Formation at 10°C in Response to Lactocin AL705

open access: yesFrontiers in Microbiology, 2021
Listeria monocytogenes is one of the major food-related pathogens and is able to survive and multiply under different stress conditions. Its persistence in industrial premises and foods is partially due to its ability to form biofilm.
