Signal processing methods for non-invasive respiration monitoring

, 2002
This thesis investigates the feasibility of using a set of non-invasive biomedical signals to monitor respiration. The signals of interest being the electrocardiogram (EGG), photoplethysmography (PPG) and impedance plethysmography (IP) signals.

The mitochondrial elongation factor LeEF-Tsmt is regulated during tomato fruit ripening and upon wounding and ethylene treatment [PDF]

, 2006
A gene encoding an elongation factor LeEF-Tsmt that participates in the protein synthesis process in mitochondria shows strong expression in ripening fruit as compared to other organs.

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

FEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

T lymphocyte subsets and mitochondrial index predict outcomes in advanced non small cell lung cancer therapy

Scientific Reports
Currently, accessible objective indicators for predicting the prognosis and treatment outcomes of non-small cell lung cancer (NSCLC) are lacking. This study investigates the potential of T lymphocyte subsets and mitochondrial biomarkers as predictors of ...

Soil respiration in a northeastern US temperate forest: a 22-year synthesis

, 2013
To better understand how forest management, phenology, vegetation type, and actual and simulated climatic change affect seasonal and inter-annual variations in soil respiration (Rs), we analyzed more than 100,000 individual measurements of soil ...

The pyruvate generator is a common phenomenon in mitochondria from different rat and mouse brain regions

FEBS Letters, EarlyView.
The pyruvate generator, which causes activation of respiration by extra‐mitochondrial Ca2+, is also present and functional in rat brainstem mitochondria, as it is in other brain regions. This finding is confirmed by experiments with a fully reconstituted malate–aspartate shuttle (MAS).

Ubiquitination of secretory granules promotes their crinophagic degradation in Drosophila

FEBS Letters, EarlyView.
Ubiquitination of secretory granules in Drosophila larval salivary glands is a critical molecular trigger for crinophagy, the lysosomal degradation of unreleased, or low‐quality granules. The E3 ubiquitin ligase Cnot4 is recruited to the surface of secretory granules to induce crinophagy.

Heat-Labile Enterotoxin-Induced PERK-CHOP Pathway Activation Causes Intestinal Epithelial Cell Apoptosis

Frontiers in Cellular and Infection Microbiology, 2017
Enterotoxigenic Escherichia coli (ETEC) is a leading cause of diarrhea among children and travelers in developing countries, and heat-labile enterotoxin (LT) is one of the most important virulence factors.
