Live cell imaging is a robust method to visualize dynamic cellular structures, especially organelles with network-like structures such as mitochondria. In this regard, mitochondrial dynamics, namely mitochondrial fission and fusion, are highly dynamic processes that regulate mitochondrial size and morphology depending on a plethora of cellular cues. Likewise, lysosome size and distribution may hint at their function and state.

Here, we show that fully functional peroxisomes, specifically peroxisomal catalase, are needed for the activation of canonical heat shock response and heat-induced hormesis in Although during heat shock, the HSP-70 chaperone is strongly up-regulated in the WT and in the absence of peroxisomal catalase (), the small heat shock proteins display modestly increased expression in the mutant. Nuclear foci formation of HSF-1 is reduced in the mutant.
View Article and Find Full Text PDFTakotsubo syndrome (TTS) is currently described as an acute and usually reversible form of systolic dysfunction of the left ventricle, which more frequently affects postmenopausal women after a stressful emotional event. Although TTS is a rare condition in premenopausal women, in recent years, the number of reported cases has increased. This manuscript reports the first case of a TTS several months after delivery in a 22-year-old woman during lactation.

Methods: methodological study, based on five phases: analysis and planning; modeling; implementation; evaluation; and distribution. Hypermedia was evaluated by expert judges, using the content validity index, index of agreement, and exact binomial distribution test, considering p > 0.
