Detection of flap venous and arterial occlusion using interstitial glucose monitoring in a rodent model.
2010
Background: Free tissue transfer necessitates vigilant postoperative monitoring for vessel occlusion. Unfortunately, most monitoring methods require experienced personnel and are expensive to use. Furthermore, many tests have low sensitivity, low specificity, or significant delay between vessel occlusion and detection. The authors report on a novel method of tissue monitoring that avoids these limitations by tracking interstitial glucose concentration. Methods: Vertical rectus abdominis myocutaneous flaps were elevated in adult rats based on the superior epigastric vessels. Interstitial glucose within the flaps was monitored using a transcutaneous sensor. Interstitial glucose was recorded f…
Functional Metabolic Diversity of Bacterioplankton in Maritime Antarctic Lakes
2021
A summer survey was conducted on the bacterioplankton communities of seven lakes from Byers Peninsula (Maritime Antarctica), differing in trophic and morphological characteristics. Predictions of the metabolic capabilities of these communities were performed with FAPROTAX using 16S rRNA sequencing data. The versatility for metabolizing carbon sources was also assessed in three of the lakes using Biolog Ecoplates. Relevant differences among lakes and within lake depths were observed. A total of 23 metabolic activities associated to the main biogeochemical cycles were foreseen, namely, carbon (11), nitrogen (4), sulfur (5), iron (2), and hydrogen (1). The aerobic metabolisms dominated, althou…

An isolierten Herzohren von Meerschweinchen wurden intracellulare Aktionspotentiale unter gleichzeitiger Registrierung der Kontraktionen abgeleitet. Untersucht wurde der Einflus des Digitoxigenins nach Barbituratschadigung und unter Calciummangel bei euthyreoten und hyperthyreoten Tieren.
Heat shock protein 27 is involved in SUMO-2/3 modification of heat shock factor 1 and thereby modulates the transcription factor activity
2009
Heat shock protein 27 (HSP27) accumulates in stressed cells and helps them to survive adverse conditions. We have already shown that HSP27 has a function in the ubiquitination process that is modulated by its oligomerization/phosphorylation status. Here, we show that HSP27 is also involved in protein sumoylation, a ubiquitination-related process. HSP27 increases the number of cell proteins modified by small ubiquitin-like modifier (SUMO)-2/3 but this effect shows some selectivity as it neither affects all proteins nor concerns SUMO-1. Moreover, no such alteration in SUMO-2/3 conjugation is achievable by another HSP, such as HSP70. Heat shock factor 1 (HSF1), a transcription factor responsib…
The role of gut micorbiome in obesity and diabetes
2019
Background Obesity and diabetes became a grooving problem in both adults and children. Many hypotheses concerned agents involved in the excessive weight gain process and it’s consequences. Not only genetic or environmental factors, but also intestinal microbiome seems to play a role in the pathophysiology of this phenomenon. Data sources A systematic review was conducted using Pubmed as the medical database source. Studies concerning connection between microbiome and metabolic disorders such as obesity and diabetes from last 10 years were analyzed. Results Intestinal bacteria may be involved both in the development of obesity, and its further complications. The pro-infammatory and immunomod…

UNRAVELLING THE ROLES OF THE NUCLEAR PROTEIN 1 DURING ER-STRESS INDUCTION
2020
Background: NUPR1 was described as a transcriptional factor involved in the regulation of various cellular stress-response genes, playing a crucial role in the condition of the endoplasmic-reticulum (ER) stress, thus emerging as a common molecular factor of different pathologies, obesity, hepatic steatosis, and cancer. In the present work we aim to explore how NUPR1 interacts with some pivotal genes that are the major modulators of the ER stress and metabolic cell functions. In particular we investigated the biochemical and molecular effects arising from the loss of NUPR1 in ER stress physiological conditions. Methods: We used prolonged high fat diet (HFD) feeding to induce ER stress physio…
From tryptophan metabolism to peptide antibiotic production in Streptomyces coelicolor
2009
The tryptophan is a precursor of the lipopeptide calcium dependent antibiotic (CDA), produced from Streptomyces coelicolor and closely related to important antibiotics such as daptomycin. We have focused our attention on the correlation between CDA production and tryptophan metabolism in order to identify new strategies aimed at increasing the production of peptide antibiotics.
