Power generation in indoor environments is the next step in dye-sensitized solar cell (DSSC) evolution. To achieve this goal, a critical recombination route which is usually inhibited by the TiCl4 -derived blocking layers (BLs), i.e., charge transfer at the fluorine-doped tin oxide (FTO) substrate/electrolyte interface, is of concern. In this study, we demonstrate that due to low surface coverage, the conventional TiCl4 BLs are unable to suppress such electron leakage, thus limiting the photovoltaic performance of Co(bpy)3 2+/3+ -mediated DSSCs (bpy = 2,2'-bipyridine) under ambient lighting...

BACKGROUND: The ability to perform high-quality cardiopulmonary resuscitation is one of the basic skills for lifeguards. The aim of the study was to assess the influence of chest compression frequency on the quality of the parameters of chest compressions performed by lifeguards. METHODS: This prospective observational, randomized, crossover simulation study was performed with 40 lifeguards working in Warsaw, Wroclaw, and Poznan, Poland. The subjects then participated in a target study, in which they were asked to perform 2-min cycles of metronome-guided chest compressions at different rates: 80, 90, 100, 110, 120, 130, 140, and 150 compressions per minute (CPM)...

BACKGROUND: Most patients transferred from a non-percutaneous coronary intervention (PCI) facility for primary PCI do not meet target reperfusion times. Direct transportation of patients with ST-elevation myocardial infarction (STEMI) from the scene by advanced life support (ALS) paramedics has been shown to improve reperfusion times and outcomes. OBJECTIVE: The aim of this study was to determine whether it is safe to bypass the closest hospital and transport by basic life support (BLS) provider to a PCI facility...

Describing the elastic deformation of single-crystal molecular solids under stress requires a comprehensive determination of the fourth-rank stiffness tensor (Cijkl ). Single crystals are, however, rarely utilized in industrial applications, and thus averaging techniques (e.g., the Voigt or Reuss approach) are employed to reduce the Cijkl (or its inverse Sijkl ) to polycrystalline aggregate mechanical moduli. With increasing elastic anisotropy, the Voigt and Reuss-averaged aggregate moduli can diverge dramatically and, provided that drug molecules almost exclusively crystallize into low-symmetry space groups, warrants a significant need for accurate aggregate mechanical moduli...

Bacterial blight (BB) and bacterial leaf streak (BLS), caused by Xanthomonas oryzae pv. oryzae and Xanthomonas oryzae pv. oryzicola , respectively, are two devastating diseases in rice planting areas worldwide. It has been proven that adoption of rice resistance is the most effective, economic, and environment-friendly strategy to avoid yield loss caused by BB and BLS. As a model system for plant-pathogen interaction, the rice- X. oryzae pathosystem has been intensively investigated in the past decade. Abundant studies have shown that the resistance and susceptibility of rice to X...

Biomechanical properties of mammalian bones, such as strength, toughness, and plasticity, are essential for understanding how microscopic-scale mechanical features can link to macroscale bones' strength and fracture resistance. We employ Brillouin light scattering (BLS) microspectroscopy for local assessment of elastic properties of bones under compression and the efficacy of the tissue engineering approach based on heparin-conjugated fibrin (HCF) hydrogels, bone morphogenic proteins, and osteogenic stem cells in the regeneration of the bone tissues...

OBJECTIVE: To analyse the acute muscular fatigue (AMF) in triceps brachii and rectus abdominis during compression-only and standard cardiopulmonary resuscitation (CPR) performed by certified basic life support providers. METHODS: Twenty-six subjects were initially recruited and randomly allocated to two study groups according to the muscles analysed; eighteen finally met the inclusion criteria (nine in each group). Both groups carried out two CPR tests (compression-only and standard CPR) of 10 min divided into five 2-min intermittent periods...

Aerobic granules were successfully cultivated at 10 °C with relatively low strength substrate. Stable granules coexisted with the batt-like sludge (BLS) were obtained in 60 days. After removing the BLS, nutrient removal performance was greatly improved and stable removal efficiencies of 99% phosphorous, 98% ammonia and 60% TN were achieved. The bacterial community structure revealed that it was an unclassified-Comamonadaceae genus dominant in the BLS, which represented for low relative abundance in mature granules...

Background: Newly qualified doctors lack competency in handling a cardiopulmonary resuscitation. The ability to recall CPR fundamentals have been shown to be inadequate. Of greater concern is that medical students over - estimate their ability to deliver such aid in a real - world setting. As most medical students are only taught adult BLS they are often unskilled and/or unhelpful in managing paediatric specific emergencies. This fact is supported by the poor outcomes demonstrated in delivering successful Paediatric Basic Life Support (PBLS)...

Enhancing CPR knowledge in schools is the key to improving bystander CPR rate and survival after an out-of-hospital cardiac arrest, but the best method to do so in a whole area is unknown. We wanted to assess if a province-based project, which involves the Secondary Schools of a whole Province, is effective in teaching schoolchildren CPR, and how well the skills are retained. We trained 100 teachers from the 21 Secondary Schools of the Province of Pavia with a BLS/AED course and we supplied each school with 10 low-budget manikins and four educational videos...

BACKGROUND: Studies in multiple countries have found that the provision of aspiration abortion care by trained nurses, midwives, and other front-line health care workers is safe and acceptable to women. In the United States, most state abortion laws restrict the provision of abortion to physicians; nurse practitioners, nurse-midwives, and physician assistants, can legally perform medication abortion in only twelve states and aspiration abortion in five. Expansion of abortion care by these providers, consistent with their scopes of practice, could help alleviate the increasing difficulty of accessing abortion care in many states...

BACKGROUND AND OBJECTIVES: Pediatric out-of-hospital cardiac arrest survival outcomes are dismal (<10%). Care that is provided in adherence to established guidelines has been associated with improved survival. Lower mortality rates have been reported in higher volume hospitals, teaching hospitals and trauma centers. The primary objective of this paper was to explore the relationship of hospital characteristics, such as annual pediatric patient volume, to adherence to pediatric cardiac arrest guidelines during an in situ simulation...

BACKGROUND: Standardised courses for laypeople in Paediatric Basic Life Support (PBLS) and Foreign Body Airway Obstruction Management (FBAOM) teach essential skills for the initiation of resuscitation by bystanders. Performance assessments are necessary to ensure that skills are acquired. We aimed to examine the validity of developed performance assessments and to determine credible pass/fail standards. METHODS: Validity evidence was gathered in a standardised simulated setting by testing participants with three different levels of PBLS/FBAOM experience: untrained laypersons, trained laypersons, and lifeguards...

Highly skilled swimmers and aquatically adaptable service members such as U.S. Navy Divers, Sea, Air and Land (SEAL) Teams, and Explosive Ordnance Disposal (EOD) technicians, die every year from drowning. Drowning is the cause of over 500,000 deaths annually across the globe. This Clinical Practice Guideline (CPG) provides an overview of drowning and associated conditions based on the best available current medical evidence. Unlike basic life support and advanced cardiac life support protocols, rescue breathing should be initiated prior to chest compressions to re-expand water-filled alveoli...

Abnormal splicing of the chloride channel 1 (CLCN1) gene causes myotonic dystrophy type 1 (DM1). Therefore, controlling the alternative splicing process of this gene by antisense oligonucleotides can be a promising treatment for DM1. In this study, we describe an efficient phosphorodiamidate morpholino oligomer (PMO) delivery method by ultrasound-mediated bubble liposomes, which is a known gene delivery tool with ultrasound exposure, to treat skeletal muscles in a DM1 mouse model, HSALR . Effective delivery of PMO using this technique can help control the alternative splicing of the Clcn1 gene via exon skipping and enhance the expression of Clcn1 protein in skeletal muscles and the amelioration of myotonia...
