Utilization of a left ventricular assist device (LVAD) as a bridge to myocardial recovery is an established therapy for acute systolic heart failure. However, device removal can present a technical challenge with no clear consensus on preferred method. In this case report, we describe a complex patient who underwent successful explantation of an LVAD using an intraoperatively constructed apical plug. This method utilizes inexpensive and easily accessible materials, minimizes ventricular distortion during device removal, and preserves the ventricular sewing ring for future reimplantation...

Timely progression of people living with HIV (PLHIV) from the point of infection through the pathway from diagnosis to treatment is important in ensuring effective care and treatment of HIV and preventing HIV-related deaths and onwards transmission of infection.  Reliable, population-based estimates of new infections are difficult to obtain for the generalised epidemics in sub-Saharan Africa.  Mortality data indicate disease burden and, if disaggregated along the continuum from diagnosis to treatment, can also reflect the coverage and quality of different HIV services...

Body-mountable electronics and electronically active garments are the future of portable, interactive devices. However, wearable devices and electronic garments are demanding technology platforms because of the large, varied mechanical stresses to which they are routinely subjected, which can easily abrade or damage microelectronic components and electronic interconnects. Furthermore, aesthetics and tactile perception (or feel) can make or break a nascent wearable technology, irrespective of device metrics...

The Bentall procedures using biological valved conduit is expanding owing to the increasing incidence of aortic valve disease in the aging population and usage for young generation. The long-term durability of the biological valve including the risks of structural valve deterioration(SVD) is the major concern of the bio-Bentall procedure. Bio-Bentall in our hospital are reviewed and literature review are added. Our surgical results of long-term survival in bio-Bentall patients is acceptable compare to other study and freedom from SVD and reoperation is better than other results...

Stable fly management is challenging because of the fly's dispersal behavior and its tendency to remain on the host only while feeding. Optically attractive traps have been used to survey and sometimes reduce adult populations. Insecticide-treated blue and black cloth targets developed for tsetse fly management in Africa were found to be attractive to stable flies in the United States, and various evaluations were conducted in Louisiana and Florida. Tests using untreated targets were designed to answer questions about configuration, size, and color relative to efficacy and stability in high winds...

The bioenergetics and molecular determinants of the metabolic response to mitochondrial dysfunction are incompletely understood, in part due to a lack of appropriate isogenic cellular models of primary mitochondrial defects. Here, we capitalize on a recently developed cell model with defined levels of m.8993T>G mutation heteroplasmy, mTUNE, to investigate the metabolic underpinnings of mitochondrial dysfunction. We found that impaired utilization of reduced nicotinamide adenine dinucleotide (NADH) by the mitochondrial respiratory chain leads to cytosolic reductive carboxylation of glutamine as a new mechanism for cytosol-confined NADH recycling supported by malate dehydrogenase 1 (MDH1)...

We develop and perform continuum mechanics simulations of carbon nanotube (CNT) deployment directed by a combination of surface topography and rarefied gas flow. We employ the Discrete Elastic Rods method to model the deposition of CNT as a slender elastic rod that evolves in time under two external forces, namely van der Waals (vdW) and aerodynamic drag. Our results confirm that this self-assembly process is analogous to a previously studied macroscopic system, the `elastic sewing machine', where an elastic rod deployed onto a moving substrate forms nonlinear patterns...

A medical quality electrocardiogram (ECG) signal is necessary for permanent monitoring, and an accurate heart examination can be obtained from instrumented underwear only if it is equipped with high-quality, flexible, textile-based electrodes guaranteeing low contact resistance with the skin. The main objective of this article is to develop reliable and washable ECG monitoring underwear able to record and wirelessly send an ECG signal in real time to a smart phone and further to a cloud. The article focuses on textile electrode design and production guaranteeing optimal contact impedance...

Incompletely seated knots (air knots) during surgical aortic valve replacement can be potentially difficult to repair in anatomically challenging areas around the aortic root. This is especially true with mechanical protheses as subvalvular areas are inaccessble once the valve is seated. In this report, we present a novel and simple technique of tightening air knots from within the aortic root without removing the prosthesis. The definitive surgical therapy for aortic valve disease has been in evolution since the advent of cardiopulmonary bypass and the development of aortic valve prostheses...

Soft shields are required to protect the human body during a radioactive accident. However, the modulus of most soft shields, such as HDPE and epoxy, is high, thereby making it difficult to process them in wearable forms like gloves and clothes. We synthesized a soft shield based on a hydrogel that is very compliant, stretchable, and biocompatible. The shields were fabricated by integrating γ-ray-shield particles into hydrogels with an interpenetrating network. The soft shields containing 3.33 M of PbO2 exhibited a high attenuation coefficient (0...

A penetrating chest trauma, a myocardial contusion or a myocardial infarction can lead to a cardiac rupture, which is linked to an extreme high death rate. Only few cases with delayed perforation of the myocardium have been reported in literature. We report about a penetrating gunshot injury, which led to a myocardial contusion with secondary delayed rupture of the left ventricle and the left inferior lobe of the lung. The leakage of the lesion in the left ventricle could be sealed sufficiently with fibrin-coated collagen fleeces after adapting stitches with Prolene 2-0...

BACKGROUND: Numerous studies have reported a strong association between temperature and mortality. Additional insights can be gained from investigating the effects of temperature on years of life lost (YLL), considering the life expectancy at the time of death. OBJECTIVES: The goal of this work was to assess the association between temperature and YLL at seven low-, middle-, and high-income sites. METHODS: We obtained meteorological and population data for at least nine years from four Health and Demographic Surveillance Sites in Kenya (western Kenya, Nairobi), Burkina Faso (Nouna), and India (Vadu), as well as data from cities in the United States (Philadelphia, Phoenix) and Sweden (Stockholm)...

Herein, we describe the development of a catalytic intramolecular "cut-and-sew" transformation between cyclobutanones and alkynes to construct cyclohexenone-fused rings. The challenge arises from the need for selective coupling at the more sterically hindered proximal position, which can be addressed using an electron-rich but less bulky phosphine ligand. The control experiment and 13C-labelling study suggest that the reaction may start with cleavage of the less hindered distal C-C bond of cyclobutanones, followed by decarbonylation and CO reinsertion to enable Rh insertion at the more hindered proximal position...

INTRODUCTION: Occupational exposure to extremely low frequency magnetic fields (ELF-MF) occurs in many occupations such as welders, electric utility workers, train drivers and sewing machine operators. There is some evidence suggesting ELF-MF exposure to be a risk factor for Alzheimer's disease (AD). The current study aims at systematically reviewing the literature and conducting a meta-analysis to evaluate the risk of AD amongst workers exposed to ELF-MF. METHODS: Bibliographic databases were searched including PubMed, EMBASE, Cochrane Library, and Web of Science in November 2017...

It is highly demanded to steer the charge flow in photocatalysts for efficient photocatalytic hydrogen reactions (PHRs). In this study, we developed a smart strategy to position MoS2 quantum dots (QDs) at the S vacancies on Zn facet in monolayered ZnIn2S4 (Vs-M-ZnIn2S4) to craft two-dimensional (2D) atomic-level heterostructure (MoS2QDs@Vs-M-ZnIn2S4). The electronic structure calculations indicated that the positive charge density of Zn atom around sulfur-vacancy (Vs) was more intensive than other Zn atoms...

Life expectancy has considerably increased over the last decades. The negative consequence of this augmented longevity has been a dramatic increase of age-related chronic neurodegenerative diseases, such as Alzheimer's, Parkinson's and multiple sclerosis. Epidemiology is telling us there exists a strong correlation between the neuronal loss characterizing these disorders and metabolic dysfunction. This review aims at presenting the evidence supporting the existence of a molecular system linking metabolism with neurodegeneration, with a specific focus on the role of two hormones with a key role in the regulatory cross talk between metabolic imbalance and the damage of nervous system: leptin and ghrelin...
