A percutaneous needle biopsy technique for sampling the supraclavicular brown adipose tissue depot of humans. [PDF]

, 2015
Brown adipose tissue (BAT) has been proposed as a potential target tissue against obesity and its related metabolic complications. Although the molecular and functional characteristics of BAT have been intensively studied in rodents, only a few studies ...

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

FEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Inhibition of the mitochondrial pyruvate carrier protects from excitotoxic neuronal death. [PDF]

, 2017
Glutamate is the dominant excitatory neurotransmitter in the brain, but under conditions of metabolic stress it can accumulate to excitotoxic levels.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Molecular bases of circadian magnesium rhythms across eukaryotes

FEBS Letters, EarlyView.
Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

Basal Area Effects on Soil Respiration Rates of a Pinus densiflora Stand

Journal of Agriculture & Life Science, 2016
This study was conducted to determine the relationship between stand and soil environmental factors, and soil respiration rates at various levels of basal area in a 40-year-old natural red pine(Pinus densiflora S. et Z.) stand in southern Korea. Soil respiration rates were measured monthly using an infrared gas analyzer system from six basal area ...

Seasonal change in acclimatised respiration rate of Temora longicornis [PDF]

, 2014
We investigated the seasonal changes in the respiration rate (R) of adult Temora longicornis (Müller) acclimatised to in situ conditions over 1 yr. Mean (±1 SE) R varied from 50.5 ± 2.8 nl O2 ind.-1 h-1 in December to 73.2 ± 3.53 nl O2 ind.-1 h-1 in ...
