[Enhancing Understanding Among Intensive Care Unit Nurses of Lower Back Musculoskeletal Disorders and Associated Risks].

Background & Problems: Work-related musculoskeletal disorders (WMSDs) have received the most attention worldwide of the various diseases addressed by the field of occupational medicine. In intensive care units (ICUs), patients with critical illness typically rely heavily on assistance provided by nurses to engage in daily life and rehabilitation activities. This dependence increases the risk of nurses experiencing WMSDs.

Single-Gate In-Transistor Readout of Current Superposition and Collapse Utilizing Quantum Tunneling and Ferroelectric Switching.

In nanostructure assemblies, the superposition of current paths forms microscopic electric circuits, and different circuit networks produce varying results, particularly when utilized as transistor channels for computing applications. However, the intricate nature of assembly networks and the winding paths of commensurate currents hinder standard circuit modeling. Inspired by the quantum collapse of superposition states for information decoding in quantum circuits, the implementation of analogous current path collapse to facilitate the detection of microscopic circuits by modifying their network topology is explored.

The Nephroprotective Effects of Leaf and Ellagic Acid and Models of Hyperuricemic Nephropathy.

Hyperuricemic nephropathy (HN) is caused by urate crystals that get deposited in the kidney and contribute to renal fibrosis. Uric acid (UA) has been proven to directly cause renal mesangial cell oxidative stress and fibrosis in the pathogenesis of HN. Some antioxidants can be used as chemopreventive agents of HN.

The Psychophysiological Profile and Cardiac Autonomic Reactivity in Long-Term Female Yoga Practitioners: A Comparison with Runners and Sedentary Individuals.

Yoga practice, a means of stress management, has been reported to optimize psychophysiological health; however, its underlying mechanisms remain unclear. The purpose of the present study was to examine the psychophysiological profile and cardiac autonomic reactivity in long-term yoga practitioners and compare them to runners and sedentary individuals. Psychological health and aerobic fitness level were evaluated using self-reported questionnaires and a 3-min step test.

The Associations between Self-Determined Motivation, Multidimensional Self-Efficacy, and Device-Measured Physical Activity.

Self-determined motivation (SDT) and self-efficacy theory have been widely used for understanding individuals' physical activity motivation and self-efficacy. However, there is a gap of evidence on the relations between SDT and multidimensional self-efficacy with device-measured physical activity in healthy adults. Questionnaires including the behavior regulation in exercise questionnaire version 2 (BREQ-2) and the multidimensional self-efficacy for exercise scale (MSES) were completed by the participants at baseline.

Affective Responses during High-Intensity Interval Exercise Compared with Moderate-Intensity Continuous Exercise in Inactive Women.

This study aimed to investigate the effects of an acute bout of high-intensity interval exercise (HIIE) and moderate-intensity continuous exercise (MICE) on affective responses in inactive women. Thirty women with normal body mass index (BMI) and 30 women with BMI ≥ 24 kg/m participated in the study. All participants completed a graded exercise test and performed two exercise sessions (HIIE and MICE) in random order.

Effects of Exergames on Physical Fitness in Middle-Aged and Older Adults in Taiwan.

Using exergaming for exercise training was found to improve physical fitness. Yet, few studies have used the "Xbox Kinect" to examine its effects on physical fitness in healthy middle-aged and older adults. The purpose of this study was to investigate the effect of 10-weeks of Xbox Kinect training on physical fitness in healthy middle-aged and older adults.

Results from the randomized controlled IHOPE trial suggest no effects of oral protein supplementation and exercise training on physical function in hemodialysis patients.

Few long-term studies have assessed whether changes in both diet and exercise can improve the health and quality of life (QOL) of hemodialysis (HD) patients. Here we examined whether 12 months of intradialytic protein supplementation and endurance exercise improves physical function, risk of cardiovascular disease (CVD), and QOL in HD patients in a randomized controlled trial (RCT). A total of 138 HD patients (average age 58 years) were assigned for 12 months to control, intradialytic protein, or protein plus exercise groups.

Natural history of myocardial deformation in children, adolescents, and young adults exposed to anthracyclines: Systematic review and meta-analysis.

Objective: Anthracyclines are widely used to treat solid and hematologic malignancies, but are known to cause cardiotoxicity. As more childhood cancer survivors reach adulthood due to improvements in oncologic treatments, they become susceptible to late and progressive anthracycline-induced cardiotoxicity. Nonetheless, diagnostic criteria for early detection of cardiac dysfunction are not well defined in children, adolescent, and young adults (CAYA, ages 1-40 years).

Aerobic exercise in anthracycline-induced cardiotoxicity: a systematic review of current evidence and future directions.

Cancer and cardiovascular disease are major causes of morbidity and mortality worldwide. Older cancer patients often wrestle with underlying heart disease during cancer therapy, whereas childhood cancer survivors are living long enough to face long-term unintended cardiac consequences of cancer therapies, including anthracyclines. Although effective and widely used, particularly in the pediatric population, anthracycline-related side effects including dose-dependent association with cardiac dysfunction limit their usage.

Effects of Pomegranate Extract Supplementation on Cardiovascular Risk Factors and Physical Function in Hemodialysis Patients.

The purpose of this study was to evaluate the effects of oral supplementation with pomegranate extract on cardiovascular risk, physical function, oxidative stress, and inflammation in hemodialysis (HD) patients. Thirty-three HD subjects were randomized to the pomegranate (POM) or placebo (CON) group. Patients in POM ingested a 1000 mg capsule of a purified pomegranate polyphenol extract 7 days/week for 6 months.

The presence and impact of diastolic dysfunction on physical function and body composition in hemodialysis patients.

Background: Cardiovascular (CV) diseases are the main cause of death in maintenance hemodialysis (MHD) patients. Muscle wasting and physical function decline are common in MHD patients, and significantly impair their quality of life. These can result from abnormalities in cardiac function, which can be further worsened by physical deconditioning.

Hemodynamic and arterial stiffness differences between African-Americans and Caucasians after maximal exercise.

African-American (AA) men have higher arterial stiffness and augmentation index (AIx) than Caucasian-American (CA) men. Women have greater age-associated increases in arterial stiffness and AIx than men. This study examined racial and sex differences in arterial stiffness and central hemodynamics at rest and after an acute bout of maximal exercise in young healthy individuals.

Arterial stiffness and walk time in patients with end-stage renal disease.

Background: End-stage renal disease patients experience increased prevalence of cardiovascular disease. Heart-artery interaction may be shifted, impacting blood pressure lability, and exercise tolerance. The coupling ratio consists of the ratio of indexed arterial elastance (EaI, arterial load) to ElvI, a measure of cardiac contractility or stiffness.

Solar cells based on block copolymer semiconductor nanowires: effects of nanowire aspect ratio.

The solution-phase self-assembly of nanowires (NWs) from diblock copolymer semiconductors, poly(3-butylthiophene)-block-poly(3-octylthiophene), of different block compositions gave crystalline NWs of similar width (13-16 nm) but a tunable average aspect ratio (length/width) of 50-260. The power conversion efficiency of bulk heterojunction solar cells comprising the diblock copolythiophene NWs and PC(71)BM was found to increase with increasing aspect ratio, reaching 3.4% at the highest average aspect ratio of 260.

Broadband absorbing bulk heterojunction photovoltaics using low-bandgap solution-processed quantum dots.

We describe bulk heterojunction (BHJ) solar cells containing blends of colloidal PbS nanocrystal quantum dots with several new donor-acceptor conjugated polymers. Using photoinduced absorption spectroscopy we found that blends of PbS quantum dots with one polymer, poly(2,3-didecyl-quinoxaline-5,8-diyl-alt-N-octyldithieno[3,2-b:2',3'-d]pyrrole) (PDTPQx), produce significantly more photoinduced charge than blends of PbS with the other donor-acceptor polymers or with traditionally studied polymers like [2-methoxy-5-(3',7'-dimethyloctyloxy)-para-phenylene vinylene] (MDMO-PPV) and poly(3-hexylthiophene) (P3HT). Photovoltaic devices made with PDTPQx/PbS blends exhibit power conversion efficiencies 10-100 times larger than previously reported BHJ blends made with IR-absorbing quantum dots.

Intradialytic exercise training reduces oxidative stress and epicardial fat: a pilot study.

Background: Cardiovascular disease (CVD) mortality rates are greatly elevated in chronic kidney disease patients receiving maintenance haemodialysis therapy. The purpose of this study was to evaluate the efficacy of intradialytic endurance exercise training on novel risk factors that may contribute to this excessive CVD risk.

Methods: Seventeen haemodialysis patients were randomized to either an intradialytic exercise training (cycling) group (EX; n = 8) or a non-exercising control group (CON; n = 9) for 4 months.

Isolation and identification of two novel SDS-resistant secreted chitinases from Aeromonas schubertii.

Two SDS-resistant endochitinases, designated as ASCHI53 and ASCHI61, were isolated from Aeromonas schubertii in a soil sample from southern Taiwan. MALDI-TOF mass measurement indicates the molecular weights of 53,527 for ASCHI53 and 61,202 for ASCHI61. N-terminal and internal amino acid sequences were obtained, and BLAST analysis of the sequences and MS/MS peptide sequencing showed that they were novel proteins.

MYC pathway is activated in clear cell renal cell carcinoma and essential for proliferation of clear cell renal cell carcinoma cells.

Clear cell renal cell carcinoma (ccRCC) is the major and aggressive subtype of RCC. Previously, we identified 383 differentially expressed genes by analyzing full-length cDNA libraries of ccRCC and normal kidney tissues. In this study, we applied functional network analysis to the differentially expressed genes for identifying deregulated molecular pathways in ccRCC, and the results indicated that MYC showed a prominent role in the highest scoring network.

Phenothiazine-phenylquinoline donor-acceptor molecules: effects of structural isomerism on charge transfer photophysics and electroluminescence.

Large differences in the intramolecular charge-transfer fluorescence quantum yields and electroluminescence efficiencies were observed among the isomeric donor-acceptor molecules 2-(4-phenyl-2-quinolyl)-10-methylphenothiazine (2PQMPT) and 3-(4-phenyl-2-quinolyl)-10-methylphenothiazine (3PQMPT). In solution, the 2PQMPT isomer had a larger positive solvatochromism and thus a greater degree of charge transfer, whereas 3PQMPT had a larger fluorescence quantum yield (71%) compared to 2PQMPT (46%). High brightness (23750 cd/m(2)) and high efficiency (8.

Inhibitory effects of nontoxic protein volvatoxin A1 on pore-forming cardiotoxic protein volvatoxin A2 by interaction with amphipathic alpha-helix.

Volvatoxin A2, a pore-forming cardiotoxic protein, was isolated from the edible mushroom Volvariella volvacea. Previous studies have demonstrated that volvatoxin A consists of volvatoxin A2 and volvatoxin A1, and the hemolytic activity of volvatoxin A2 is completely abolished by volvatoxin A1 at a volvatoxin A2/volvatoxin A1 molar ratio of 2. In this study, we investigated the molecular mechanism by which volvatoxin A1 inhibits the cytotoxicity of volvatoxin A2.
