Nutrients intake, and serum calcium and phosphorus levels: An evidence ‐based study
ConclusionWe found that the dietary intake of Ca was not sufficient in our population and was associated with the dietary intake of some macro‐ and micronutrient, supporting further investigation on clinical impact of this condition on calcium/phosphorus deficiency related diseases.

Passive Wearable Skin Patch Sensor Measures Limb Hemodynamics Based on Electromagnetic Resonance
Conclusion: The sensor was able to detect pulsatile flow, identify hemodynamic waveform features, and measure heart rate with 98% accuracy. Significance: The open-circuit resonant sensor design leverages the architecture of a thin planar spiral which is passive (does not require batteries), robust and lightweight (does not have electrical components or electrical connections), and may be able to wirelessly monitor cardiovascular health and limb hemodynamics.

Publication date: Available online 6 August 2018Source: Journal of Materials Processing TechnologyAuthor(s): Tim Mittler, Thomas Greß, Martin Feistle, Michael Krinninger, Uwe Hofmann, Joachim Riedle, Roland Golle, Wolfram VolkAbstractA novel process chain for the production of metallurgically bonded copper bimetal parts was developed and investigated. This process chain offers a high potential for being an energy- and resource-efficient alternative to cold roll bonding. Research activities in the present paper focused on both the initial bonding between pure copper and tin bronze using horizontal continuous compound casti...

Association Between Hypertension in Healthy Participants and Zinc and Copper Status: a Population-Based Study.
Abstract The prevalence of hypertension (HTN) is increasing globally. It has been shown that there is an association between micronutrient deficiency and HTN. In the current study, we aimed to assess the association between HTN with serum copper and zinc concentrations in a large representative Iranian population. The participants were enrolled into the Mashhad stroke and heart atherosclerotic disorders study (MASHAD study), a cohort study that was initiated in 2010. Anthropometric indices were assessed using standard procedures. Systolic (SBP) and diastolic (DBP) blood pressures were measured using a standard mer...

Association Between Trace Element Status and Depression in HTLV-1-Infected Patients: a Retrospective Cohort Study.
Abstract Depression and Anxiety are two important public health problems that are known to be associated with viral infections. The association between the intake of nutrients such as zinc and copper with symptoms of depression has been studied previously. The aim of the current study was to investigate the association between depression with human T cell lymphotropic virus type 1 (HTLV-1) infection and serum content of zinc and copper in a large Iranian population cohort. The study population consisted of 279 HTLV-1-positive patients who were identified after recruitment as part of a large cohort study: the Mashh...

A comprehensive study on emission and performance characteristics of a diesel engine fueled with nanoparticle-blended biodiesel.
Abstract The present work is aimed to analyze the performance and emission characteristics of mahua biodiesel-fueled diesel engine with copper oxide nanoparticle at various particle sizes (10 and 20 nm) and the results compared with conventional diesel fuel (BD). Experiments were conducted in a four-stroke, single-cylinder, constant speed, and naturally aspirated research diesel engine with an eddy current dynamometer. Conventional transesterification process is carried out to convert the raw mahua oil into mahua oil biodiesel (BD100). Copper oxide (CuO) was chosen as a nanoparticle; the mass fraction of 100 ppm...

Safe coordinated trafficking of heme and iron with copper maintain cell homeostasis: modules from the hemopexin system.
Abstract Studies with patients, animal models of human disease and hemopexin null mice have shown that the heme-binding protein hemopexin is vital for the protection of a variety of cell types and tissues against heme toxicity. The presence of hemopexin in all biological fluids examined to date indicates wide roles in abrogating heme toxicity in human tissues; and, thus, is clinically relevant. Heme-hemopexin endocytosis leads to coordinated trafficking of heme, iron and copper as heme traffics from endosomes to heme oxygenases (HOs) in the smooth endoplasmic reticulum and to the nucleus. This is safe redox-metal ...

Current Challenges for Imaging of Hypoxia in 2019
1128Introduction: Tissues with low levels of oxygen often respond poorly to radiation therapy and chemo / immune therapies. Hypoxia in tumor bearing tissue is associated with worse clinical outcome and this has been known for over 50 years. Alterations to radiation therapy planning via providing localized boost to hypoxic tissues cannot be made without knowing exactly where hypoxia exists. However, there is no FDA approved agent to assess for hypoxia in tumor tissues, there is no accepted standard methodology for measuring hypoxia in patients, nor are there FDA approved agents for treating hypoxia. There are multiple PET i...

Transcranial Magnetic Stimulation as Treatment in Multiple Neurologic Conditions
AbstractPurpose of ReviewTranscranial magnetic stimulation (TMS) is a method of Non-Invasive Brain Stimulation that is based on electro-physical principles discovered by Michael Faraday. A TMS device is made of one or two copper coils, positioned superficially to a site of interest in the brain, to non-invasively produce a brief magnetic pulse to an estimated depth from the surface of the scalp with the following axonal depolarization. This axonal depolarization activates cortical and subcortical networks with multiple effects. There are different methods of TMS used, all with different mechanisms of action. TMS is well to...

Serum Ceruloplasmin Is the Candidate Predictive Biomarker for Acute Aortic Dissection and Is Related to Thrombosed False Lumen: a Propensity Score-Matched Observational Case-Control Study.
Abstract Acute aortic dissection (AAD), one of the fatal diseases observed at the department of vascular surgery, is associated with a great mortality rate at the early stage. Ceruloplasmin (CP) is the plasma protein that functions as a copper transporter. The current retrospective research was carried out to assess CP contents and to examine the possible part in diagnosing patients with AAD. In addition, propensity score matching (PSM) was also utilized for reducing the bias in case screening as well as the clinical confounders. Using PSM, this study included 85 pairs of AAD cases (Stanford A and B dissection) an...

Clinical Manifestations of Copper Deficiency: A Case Report and Review of the Literature.
CONCLUSIONS: Our patient presented with copper deficiency secondary to malabsoprtion. This case highlights the importance of copper testing in the bariatric surgery population and in patients with short-bowel syndrome. Given the irreversible nature of neurological symptoms when compared with the expense of nutrition supplements, routine copper testing should be considered in patients with malabsorptive states or altered anatomy, regardless of initial presentation.

The utility of electrocardiography and echocardiography in copper deficiency-induced cardiac damage in goats.
In conclusion, CuD disturbs hemato-biochemical parameters and results in myocardial damage and cardiac dilatation that increases some ECG and echocardiographic parameters without development of systolic dysfunction. The ECG and echocardiography can potentially detect cardiac changes in long-lasting CuD in goats. PMID: 33037959 [PubMed - as supplied by publisher]

Cytochrome c oxidase ‐modulatory near‐infrared light penetration into the human brain: Implications for the noninvasive treatment of ischemia/reperfusion injury
AbstractNear ‐infrared light (IRL) has been evaluated as a therapeutic for a variety of pathological conditions, including ischemia/reperfusion injury of the brain, which can be caused by an ischemic stroke or cardiac arrest. Strategies have focused on modulating the activity of mitochondrial electron transpor t chain (ETC) enzyme cytochromec oxidase (COX), which has copper centers that broadly absorb IRL between 700 and 1,000  nm. We have recently identified specific COX‐inhibitory IRL wavelengths that are profoundly neuroprotective in rodent models of brain ischemia/reperfusion through the following mechanism: COX ...
