A model-based source separation algorithm for lung perfusion imaging using electrical impedance tomography.

Physiol Meas 2021 Jun 24. Epub 2021 Jun 24.

Medical Information Technology, RWTH Aachen University, Aachen, Nordrhein-Westfalen, GERMANY.

Objective: Electrical impedance tomography (EIT) for lung perfusion imaging is attracting considerable interest in intensive care, as it might open up entirely new ways to adjust ventilation therapy. A promising technique is bolus injection of a conductive indicator to the central venous catheter, which yields the indicator-based signal (IBS). Lung perfusion images are then typically obtained from the IBS using the maximum slope technique. Read More

An update of the molecular mechanisms underlying doxorubicin plus trastuzumab induced cardiotoxicity.

Life Sci 2021 Jun 21:119760. Epub 2021 Jun 21.

LAQV/REQUIMTE, Department of Chemistry, University of Aveiro, Aveiro, Portugal. Electronic address:

Cardiotoxicity is a major side effect of the chemotherapeutic drug doxorubicin (Dox), which is further exacerbated when it is combined with trastuzumab, a standard care approach for Human Epidermal growth factor Receptor-type 2 (HER2) positive cancer patients. However, the molecular mechanisms of the underlying cardiotoxicity of this combination are still mostly elusive. Increased oxidative stress, impaired energetic substrate uses and topoisomerase IIB inhibition are among the biological processes proposed to explain Dox-induced cardiomyocyte dysfunction. Read More

Assessing species reintroduction sites based on future climate suitability for food resources.

Conserv Biol 2021 Jun 24. Epub 2021 Jun 24.

Universidade do Estado de Mato Grosso (UNEMAT), Faculdade de Ciências Biológicas e Agrárias, Alta Floresta, Brazil.

The reintroduction of a species that is extinct in the wild demands caution because reintroduction locations may be associated with threats, such as hunting, poor-quality habitat, and climate change. This is the case for Cyanopsitta spixii (Spix's Macaw), which has been extinct in the wild since 2000. The few living individuals were created in captivity and will be used in a reintroduction project within the species' original distribution area, the Caatinga domain (Brazil). Read More

A mixed method study design to explore the adherence of haematological cancer patients to oral anticancer medication in a multilingual and multicultural outpatient setting: The MADESIO protocol.

PLoS One 2021 24;16(6):e0253526. Epub 2021 Jun 24.

Centre for Research in Epidemiology, Biostatistics, and Clinical Research, School of Public Health, Université Libre de Bruxelles, Brussels, Belgium.

Background: Patients with haematologic malignancies are increasingly treated by oral anticancer medications, heightening the challenge of ensuring optimal adherence to treatment. However, except for chronic myelogenous leukaemia or acute lymphoid leukaemia, the extent of non-adherence has rarely been investigated in outpatient settings, particularly for migrant population. With growing numbers of migrants in Belgium, identifying potential differences in drug use is essential. Read More

Exploring the Potential of Electrospray-Orbitrap for Stable Isotope Analysis Using Nitrate as a Model.

Anal Chem 2021 Jun 24. Epub 2021 Jun 24.

Institute of Arctic and Alpine Research, University of Colorado, Boulder, Colorado 80303, United States.

Widely used isotope ratio mass spectrometers have limited capabilities to measure metabolites, drugs, or small polyatomic ions without the loss of structural isotopic information. A new approach has recently been introduced that uses electrospray ionization Orbitrap to measure multidimensional isotope signatures of intact polar compounds. Using nitrate as a model compound, this study aims to establish performance metrics for comparisons with conventional IRMS at the natural abundance level. Read More

Small artificial waterbodies are widespread and persistent emitters of methane and carbon dioxide.

Glob Chang Biol 2021 Jun 24. Epub 2021 Jun 24.

Department of Aquatic Sciences and Assessment, Swedish University of Agricultural Sciences, 756 51, Uppsala, Sweden.

Inland waters play an active role in the global carbon cycle and emit large volumes of the greenhouse gases (GHGs) methane (CH ) and carbon dioxide (CO ). A considerable body of research has improved emissions estimates from lakes, reservoirs, and rivers but recent attention has been drawn to the importance of small, artificial waterbodies as poorly quantified but potentially important emission hotspots. Of particular interest are emissions from drainage ditches and constructed ponds. Read More

Powering Electronic Devices from Salt Gradients in AA-Battery-Sized Stacks of Hydrogel-Infused Paper.

Adv Mater 2021 Jun 24:e2101757. Epub 2021 Jun 24.

Adolphe Merkle Institute, University of Fribourg, Chemin des Verdiers 4, Fribourg, 1700, Switzerland.

Strongly electric fish use gradients of ions within their bodies to generate stunning external electrical discharges; the most powerful of these organisms, the Atlantic torpedo ray, can produce pulses of over 1 kW from its electric organs. Despite extensive study of this phenomenon in nature, the development of artificial power generation schemes based on ion gradients for portable, wearable, or implantable human use has remained out of reach. Previously, an artificial electric organ inspired by the electric eel demonstrated that electricity generated from ion gradients within stacked hydrogels can exceed 100 V. Read More

Entrainment of Network Activity by Closed-Loop Microstimulation in Healthy Ambulatory Rats.

Cereb Cortex 2021 Jun 24. Epub 2021 Jun 24.

Department of Rehabilitation Medicine, University of Kansas Medical Center, Kansas City 66160, USA.

As our understanding of volitional motor function increases, it is clear that complex movements are the result of the interactions of multiple cortical regions rather than just the output properties of primary motor cortex. However, our understanding of the interactions among these regions is limited. In this study, we used the activity-dependent stimulation (ADS) technique to determine the short/long-term effects on network activity and neuroplasticity of intracortical connections. Read More

KPI-121 1% for pain and inflammation in ocular surgery.

Pain Manag 2021 Jun 24. Epub 2021 Jun 24.

Northwest Eye Surgeons, Seattle, WA 98133, USA.

Pain and inflammation are common experiences following ocular surgery and, if uncontrolled, can compromise patients' vision, functioning and quality of life. Corticosteroid drugs are available to manage inflammation and discomfort but have limitations in penetrating the ocular mucus barrier to reach the target ocular tissues. KPI-121 1% (INVELTYS) is a novel formulation of loteprednol etabonate that employs innovative proprietary technology to deliver nanoparticle-sized mucus-penetrating particles to the cornea.

Fiber-based photoacoustic remote sensing microscopy and spectral-domain optical coherence tomography with a dual-function 1050-nm interrogation source.

J Biomed Opt 2021 Jun;26(6)

Univ. of Alberta, Canada.

Significance: Spectral-domain optical coherence tomography (SD-OCT) offers depth-resolved imaging of optical scattering contrast but is limited in sensitivity to optical absorption. Dual-modality imaging combined with the noncontact absorption contrast of photoacoustic remote sensing (PARS) microscopy can augment SD-OCT applications with specific molecular and functional contrasts in an all-optical, fiber-based platform.

Aim: To develop a fiber-based multimodal PARS and SD-OCT imaging system, which efficiently uses a common 1050-nm light source for SD-OCT and PARS interrogation. Read More

Lifetime climate impacts of diet transitions: a novel climate change accounting perspective.

Sustainability 2021 May 17;13(10):5568. Epub 2021 May 17.

Ministry for Primary Industries, PO Box 2526, Wellington 6140, New Zealand.

Dietary transitions, such as eliminating meat consumption, have been proposed as one way to reduce the climate impact of the global and regional food systems. However, it should be ensured that replacement diets are indeed nutritious and that climate benefits are accurately accounted for. This study uses New Zealand food consumption as a case study for exploring the cumulative climate impact of adopting the national dietary guidelines and the substitution of meat from hypothetical diets.
