BACKGROUND: Currently, people live longer but often with poor quality of life. The decrease in healthy life-years is partly attributable to the institution of polypharmacy to treat various comorbidities. OBJECTIVES: The objectives of the study were to determine the prevalence and nature of drug-related problems (DRPs) in polypharmacy elderly patients residing in nursing homes and to test the acceptability of a pharmacist's intervention. METHODS: An exposure cohort was constituted in three Portuguese nursing homes, where all polypharmacy (five or more medicines) elderly patients (≥65 years of age) were analysed and then a random stratified sample was extracted to be subject to an intervention...

PURPOSE: Phosphorus (P) lost from agricultural land by erosion, runoff, throughflow and leaching is of major concern for water resource managers worldwide. Previous study on soils from cropping land of southwest Western Australia suggested P loss as dissolved unreactive P (DURP) via leaching, but the implications for processes and rates of P transport in soils are not known. MATERIAL AND METHODS: Two contrasting soil profiles (sand and loam) from cropping land of southwest Western Australia were exposed to artificial rain in packed boxes and field runoff plots to examine P forms and fluxes in runoff, throughflow, leachate and soil solution after three P rates of application (equivalent to 0, 20 and 40kg P/ha)...

Elevated phosphorus (P) loading from agricultural nonpoint-source pollution continues to impair inland waterbodies throughout the world. The application of flue gas desulfurization (FGD) gypsum to agricultural fields has been suggested to decrease P loading because of its high calcium content and P sorbing potential. A before-after control-impact paired field experiment was used to examine the water quality effects of successive FGD gypsum applications (2.24 Mg ha; 1 ton acre each) to an Ohio field with high soil test P levels (>480 ppm Mehlich-3 P)...

Rev1 is a member of the Y-family of DNA polymerases and is known for its deoxycytidyl transferase activity that incorporates dCMP into DNA and its ability to function as a scaffold factor for other Y-family polymerases in translesion bypass events. Rev1 also is involved in mutagenic processes during somatic hypermutation of immunoglobulin genes. In light of the mutation pattern consistent with dCMP insertion observed earlier in mouse fibroblast cells treated with a base excision repair-inducing agent, we questioned whether Rev1 could also be involved in base excision repair (BER)...

Many coastal rivers have a system of cascade reservoirs, but the role of these reservoirs in regulating nutrient transport from watershed to coast is still unknown. In this study, phosphorus (P) in surface water and top sediment was investigated along the North Jiulong River (southeast China) under three hydrological conditions (high flow, medium flow and low flow) in 2012-2013, and P dynamics in a cascade reservoir (Xipi Reservoir) were studied on a monthly scale. Results showed that the concentrations of dissolved reactive phosphorus (DRP) consistently decreased longitudinally in the upper river with the lowest values observed in the section of cascade reservoirs, likely due to tributary inputs and in situ uptakes...

We sought to investigate effects of exercise training on apoptosis-related microRNAs (miRs) and their validated targets, discussing molecular mechanism of the exercise-induced benefit in heart. Male C57BL/6 mice were randomly assigned to three groups: sedentary (SE), exercise training 1 (ET1) and exercise training 2 (ET2). ET1 swam for 8 weeks, once a day and 5 days per week with incremental load. ET2 performed the same work as ET1 and switched to twice a day by the end of the 5th week. In ET2, positive cell rate (%) tested by TUNEL assay decreased significantly (p < 0...

Traumatic brain injury (TBI) remains one of the leading causes of death and disability worldwide. Mild TBI may lead to neuropsychiatric sequelae, including memory loss and motor impairment. Mitochondrial dysfunction and oxidative stress have a contributory role in several neurological disorders; however, their association with mitophagy in mild TBI is unclear. TBI was induced in female Sprague Dawley (SD) rats using a New York University Impactor (10g, impactor head 2.5mm diameter, weight drop 50mm) and compared to sham surgery controls...

Base excision repair (BER) is a flagship DNA repair system responsible for maintaining genome integrity. Apart from basal enzymes, this system involves several accessory factors essential for coordination and regulation of DNA processing during substrate channeling. Y-box-binding protein 1 (YB-1), a multifunctional factor that can interact with DNA, RNA, poly(ADP-ribose) and plenty of proteins including DNA repair enzymes, is increasingly considered as a non-canonical protein of BER. Here we provide quantitative characterization of YB-1 physical interactions with key BER factors such as PARP1, PARP2, APE1, NEIL1 and pol β and comparison of the full-length YB-1 and its C-terminally truncated nuclear form in regard to their binding affinities for BER proteins...

BACKGROUND: Preterm birth is a major cause of neonatal mortality, especially in low and middle income countries. Antenatal corticosteroid therapy for foetal maturation could have a significant impact and therefore is often referred to as an important strategy to reduce neonatal mortality. A recently conducted large multinational trial showed that antenatal corticosteroids can have adverse effects in low income countries, but this is likely to depend on the specific setting. In our hospital preterm birth is only recognized in patients with severe maternal disease, due to physician-initiated delivery...

Small oligomeric forms of amyloid-β (Aβ) are believed to be the culprit for declined brain functions in AD in part through their impairment of neuronal trafficking and synaptic functions. However, the precise cellular actions of Aβ oligomers and underlying mechanisms in neurons remain to be fully defined. Previous studies have identified mitochondria as a major target of Aβ toxicity contributing to early cognitive decline and memory loss in neurodegenerative diseases including Alzheimer's disease (AD). In this study, we report that Aβ oligomers acutely elicit distinct effects on the transport and integrity of mitochondria...

Nanomolar intravascular concentrations of drag-reducing polymers (DRP) have been shown to improve hemodynamics and survival in animal models of ischemic myocardium and limb, but the effects of DRP on the cerebral microcirculation have not yet been studied. We recently demonstrated that DRP enhance microvascular flow in normal rat brain and hypothesized that it would restore impaired microvascular perfusion and improve outcomes after focal ischemia and traumatic brain injury (TBI). We studied the effects of DRP (high molecular weight polyethylene oxide, 4000 kDa, i...

Land application of dairy soiled water (DSW) is expensive relative to its nutrient replacement value. The use of aerobic filters is an effective alternative method of treatment and potentially allows the final effluent to be reused on the farm. Knowledge gaps exist concerning the optimal design and operation of filters for the treatment of DSW. To address this, 18 laboratory-scale filters, with depths of either 0.6 m or 1 m, were intermittently loaded with DSW over periods of up to 220 days to evaluate the impacts of depth (0...

Maintenance of a healthy pool of mitochondria is important for the function and survival of terminally differentiated cells such as cardiomyocytes. Epoxyeicosatrienoic acids (EETs) are epoxy lipids derived from metabolism of arachidonic acid by cytochrome P450 epoxygenases. We have previously shown that EETs trigger a protective response limiting mitochondrial dysfunction and reducing cellular death. The aim of this study was to investigate whether EET-mediated effects influence mitochondrial quality in HL-1 cardiac cells during starvation...
