A neonate with aseptic cutaneous necrosis related to the migration of the proximal central venous catheter infusion port
We report a case of aseptic cutaneous necrosis from extravasation of calcium chloride at the proximal port of a central venous catheter (CVC). A right internal jugular CVC was placed with ultrasound guidance using contemporary guidelines for size and insertion site. Catheter migration occurred concurrent with development of postoperative anasarca. Four days later, leakage of infusate with skin necrosis was noted at the insertion site. Despite initial proper positioning, catheter ports can migrate out of intravascular structures due to postprocedural subcutaneous edema. Intravascular confirmation should be performed regular...

Characterization of landfills solid waste in Muscat and estimation of their energy recovery
In this study, MSW from Muscat Governorate landfills is examined. The MSW samples were collected et al. Amerat and Barka landfills in 2020 in order to determine some of the importance of their physiochemical properties and the ratio of materials (food, plastic, and paper). It was found that approximately 50% of the weight of the disposed waste was recyclable. There were high levels of biodegradable organic material in MSW. In terms of moisture content, MSW ranged from 21.5 to 43.3%. Both the volatility and loss of ignition of MSW were high. It was found that the total oxide ratios ranged from 12.4 to 44.06%. The elemental ...

Modulation of Oxidized Low-density Lipoprotein-Affected Macrophage Efferocytosis by Mitochondrial Calcium Uniporter in a Murine Model
CONCLUSIONS: In this study, we found that MCU inhibition modulated intracytoplasmic Ca2+ concentration, improved impaired Mø efferocytosis, and reduced ROS generation. Macrophage efferocytosis removed apoptotic cells and prevented the release of inflammatory factor and foam cell formation, and this can be a potential new therapeutic target for alleviating atherosclerosis.PMID:37689315 | DOI:10.1016/j.imlet.2023.09.003

Molecules, Vol. 28, Pages 6482: Morphoanatomical, Histochemical, and Essential Oil Composition of the Plectranthus ornatus Codd. (Lamiaceae)
In this study, leaves of P. ornatus were collected in two cities of the state of Pará, “Quatipuru” and “Barcarena”, and were used with the objective of analyzing, through morphoanatomical data and histochemical and phytochemical studies of essential oil, the samples present structural differences and differences in their chemical composition. Anatomical and histochemical analyses were performed by transverse, using longitudinal sections of 8 μm to 10 μm to perform epidermal dissociation, diaphonization, and tests to identify classe...

Mixed whey and pea protein based cold-set emulsion gels induced by calcium chloride: Fabrication and characterization
Int J Biol Macromol. 2023 Aug 30:126641. doi: 10.1016/j.ijbiomac.2023.126641. Online ahead of print.ABSTRACTThe cold-set gels of oil-in-water emulsions stabilized by mixtures of whey protein isolate (WPI) and pea protein isolate (PPI) with mass ratios of 10:0, 7:3, 5:5, 3:7, and 0:10 were investigated to evaluate the possibility of pea protein to replace milk protein. Particle size and surface charge of emulsions increased and decreased with raised PPI content, respectively. The redness and yellowness of emulsion gels were strengthened with elevated pea protein percentage and independent of calcium concentration applied. C...

Characterization of airborne particulate matter and its toxic and proarrhythmic effects: A case study in Aburr á Valley, Colombia
This study characterized the PM collected from the north, south, and central zones to evaluate its chemical composition and morphology. Different elements such as silicon, carbon, aluminum, potassium, calcium, sodium, iron, magnesium, and copper and the presence of unburned fuel, motor oil, and silicon fibers were identified. In vitro and in silico studies were conducted to evaluate the toxicity of the PM, and it was found that the PM collected from the central zone had the greatest impact on cell viability and caused DNA damage. The in silico study demonstrated that PM has concentration-dependent proarrhythmic effects, re...

Retinal stroke: research models, targets and experimental drugs
Expert Opin Investig Drugs. 2023 Aug 31. doi: 10.1080/13543784.2023.2254688. Online ahead of print.ABSTRACTINTRODUCTION: Retinal artery occlusion (RAO), often caused by a microembolus and resulting in inner retinal ischemia, could be considered as the retinal analogue to cerebral stroke. Although several therapeutic targets have been suggested in animal models of retinal ischemia and several potential treatments have been evaluated on small series of patients, central retinal artery occlusion (CRAO) is still rarely treatable in clinical practice.AREAS COVERED: Here, we review several animal models of RAO, including increas...

A systematic review of contrast-enhanced computed tomography calcium scoring methodologies and impact of aortic valve calcium burden on TAVI clinical outcomes
This systematic review examines the role of aortic valve calcification (AVC) on transcatheter aortic valve implantation (TAVI) outcomes. Sixty-eight studies were included, reporting varied methodologies for quantifying AVC. AVC quantification methodology with contrast-enhanced CT was found to be variable. A positive association between calcium burden and increased risk of adverse outcomes, including permanent pacemaker implantation, paravalvular leak, and aortic rupture, was reported. AVC negatively impacts TAVI outcomes independently of the quantification method.
