Spatiotemporal dynamics of aboveground biomass (AGB) is a fundamental problem for grassland environmental management on the Qinghai-Tibet Plateau (QTP). Moderate Resolution Imaging Spectroradiometer (MODIS) Normalized Difference Vegetation Index (NDVI) data can feasibly be used to estimate AGB at large scales, and their precise validation is necessary to utilize them effectively. In our study, the clip-harvest method was used at 64 plots in QTP grasslands to obtain actual AGB values, and a handheld hyperspectral spectrometer was used to calculate field-measured NDVI to validate MODIS NDVI...

The purpose of this study was to assess the association of GI events with HRQoL and treatment satisfaction. The effect of baseline GI events persisted through 1 year of follow-up, as indicated by lower EQ-5D, OPAQ-SV, and treatment satisfaction scores among patients with vs without baseline GI events. The presence of GI events is an independent predictor of decreased HRQoL and treatment satisfaction in patients being treated for osteoporosis. INTRODUCTION: The goal of this study was to assess the association of gastrointestinal (GI) events with health-related quality of life (HRQoL) and treatment satisfaction in patients being treated for osteoporosis...

The Yellow Sea is a shallow marginal sea with a large tidal range. In this study, ten areas located along the western coast of the Korean Peninsula are investigated with respect to remotely sensed water quality indicators derived from NASA MODIS aboard of the satellite Aqua. We found that there was a strong seasonal trend with spatial heterogeneity. In specific, a strong six-month phase-lag was found between chlorophyll-a and total suspended solid owing to their inversed seasonality, which could be explained by different dynamics and environmental settings...

BACKGROUND: Autism spectrum disorder (ASD) is a clinically and biologically heterogeneous condition characterized by social, repetitive, and sensory behavioral abnormalities. No treatments are approved for the core diagnostic symptoms of ASD. To enable the earliest stages of therapeutic discovery and development for ASD, robust and reproducible behavioral phenotypes and biological markers are essential to establish in preclinical animal models. The goal of this study was to identify electroencephalographic (EEG) and behavioral phenotypes that are replicable between independent cohorts in a mouse model of ASD...

We show that addition of nanozeolite (NZ) and vitamin E D-α-Tocopherol polyethylene glycol succinate (TPGS or T) considerably improves the performance of polyethersulfone (PES or P) hollow fiber membrane (HFM) for hemodialysis. Nanocomposite HFMs were manufactured using PES as a polymer, TPGS as an additive and NZ as a filler to give a composite membrane called PT-NZ. HFMs were spun by dry-wet spinning principle based on liquid-liquid phase separation. TPGS and NZ were successfully incorporated in HFMs, as confirmed by EDX elemental mapping...

Parkinson's disease (PD) is a multifactorial progressive neurological disorder. Pathological hallmarks of PD are characterized by the presence of α-synuclein (αSyn) aggregates known as Lewy bodies. αSyn aggregation is one of the leading causes for the neuronal dysfunction and death in PD. It is also associated with neurotransmitter and calcium release. Current therapies of PD are limited to only symptomatic relief without addressing the underlying pathogenic factors of the disease process such as aggregation of αSyn...

Brain metastases are known to be present with a history of increased intra-cranial pressure headache, seizures or altered sensorium. Corresponding to the clinical brain metastases are the most feared complication of a systemic cancer. Classically, brain metastases are associated with significant morbidity and are known to present with a history of increased intracranial pressure headache, seizures or altered sensorium. Neuroimaging is usually suggestive of massive peri-lesional edema and mass effect surrounding the space occupying lesions...

The occurrence and related risks from cyanobacterial blooms have increased world-wide over the past 40 years. Information on the abundance and distribution of cyanobacteria is fundamental to support risk assessment and management activities. In the present study, an approach based on Empirical Orthogonal Function (EOF) analysis was used to estimate the concentrations of chlorophyll a (Chla) and the cyanobacterial biomarker pigment phycocyanin (PC) using data from the MODerate resolution Imaging Spectroradiometer (MODIS) in Lake Chaohu (China's fifth largest freshwater lake)...

BACKGROUND: Meticulous tracking of study data must begin early in the study recruitment phase and must account for regulatory compliance, minimize missing data, and provide high information integrity and/or reduction of errors. In behavioral intervention trials, participants typically complete several study procedures at different time points. Among HIV-infected patients, behavioral interventions can favorably affect health outcomes. In order to empower newly diagnosed HIV positive individuals to learn skills to enhance retention in HIV care, we developed the behavioral health intervention Integrating ENGagement and Adherence Goals upon Entry (iENGAGE) funded by the National Institute of Allergy and Infectious Diseases (NIAID), where we deployed an in-clinic behavioral health intervention in 4 urban HIV outpatient clinics in the United States...

Understanding the long-term performance of global satellite leaf area index (LAI) products is important for global change research. However, few effort has been devoted to evaluating the long-term time series consistencies of LAI products. This study compared four long-term LAI products (GLASS, GLOBMAP, LAI3g, and TCDR) in terms of trends, interannual variabilities and uncertainty variations from 1982 through 2011. This study also used four ancillary LAI products (GEOV1, MERIS, MODIS C5, and MODIS C6) from 2003 through 2011 to help clarify the performances of the four long-term LAI products...

Land Use and Land-use Changes (LULUC) information is essential to determine the environmental impacts of anthropogenic land-use and conversion. However, existing datasets are either local-scale or they quantify land occupation per land-use type rather than providing information on land-use changes. Here we combined the strengths of the remotely-sensed MODIS land cover dataset and FAOSTAT land-use data to obtain a database including a collection of 231 country-specific LULUC matrixes, as suggested by the IPCC...

Most renal traumas are successfully managed conservatively. Grade 4 and 5 trauma, however, can require nephrectomy which is almost always by laparotomy and laparoscopic nephrectomy (LN) is still considered contraindicated in acute trauma setting. We report successful transperitoneal LN in an acute grade 4 renal trauma with retroperitoneal haematoma, extensive parenchymal devascularisation and urinary extravasation though retroperitoneoscopic nephrectomy in trauma has been reported recently. However, we believe transperitoneal approach is more logical and replicates all the principles of open renal trauma surgery more accurately...

Viperin is an IFN-inducible radical S-adenosylmethionine (SAM) enzyme that inhibits viral replication. We determined crystal structures of an anaerobically prepared fragment of mouse viperin (residues 45-362) complexed with S-adenosylhomocysteine (SAH) or 5'-deoxyadenosine (5'-dAdo) and l-methionine (l-Met). Viperin contains a partial (βα)6-barrel fold with a disordered N-terminal extension (residues 45-74) and a partially ordered C-terminal extension (residues 285-362) that bridges the partial barrel to form an overall closed barrel structure...

The left main coronary artery (LMCA) is responsible for supplying the majority of the left ventricular myocardium. Visual estimation of stenosis severity on angiography has major limitations and methods to assess functional significance, such as Fractional Flow Reserve (FFR), have been shown to yield better outcomes but major trials examining the use of such physiological indices have excluded LMCA disease to date. Furthermore, LMCA disease commonly co-exists with downstream disease, which complicates interpretation of coronary physiological data...

Squamous cell carcinoma of the head and neck (SCCHN) is a difficult to treat malignancy and represents the seventh most common cancer worldwide. Systemic therapy has a critical role in the treatment of locally advanced and recurrent/metastatic disease. Cytotoxic chemotherapy has been primarily used along with radiation and surgery, with cisplatin being the standard of care choice of therapy. When contraindications to cisplatin exist, other agents such as carboplatin, taxanes, 5-fluorouracil, and cetuximab are used...

An ecosystem disruptive bloom of red Noctiluca scintillans (hereafter Noctiluca) was observed in coastal waters of the north-western Bay of Bengal during April 2014. Based on the principle of phytoplankton group/species specific remote sensing reflectance (Rrs), a technique of detecting green Noctiluca and diatom was developed earlier using Rrs at 443, 488, and 531 nm of Moderate Imaging Spectroradiometer-Aqua (MODIS). This was appropriately modified to detect bloom of red Noctiluca in coastal waters of the Bay of Bengal...

BACKGROUND: To facilitate the delivery of proven maternal, neonatal, and child health (MNCH) services, a new cadre of village-based frontline workers, called the Accredited Social Health Activists (ASHAs), was created in 2005 under the aegis of the National Rural Health Mission in India. Evaluations have noted that coverage of selected MNCH services to be delivered by the ASHAs is low. Reasons for low coverage are inadequate supervision and support to ASHAs apart from insufficient skills, poor quality of training, and complexity of tasks to be performed...

Ecosystem water-use efficiency (WUE) plays an important role in carbon and water cycles. Currently, the response of WUE to drought disturbance remains controversial. Based on the global ecosystem gross primary productivity (GPP) product and the evapotranspiration product (ET), both of which were retrieved from the moderate resolution imaging spectroradiometer (MODIS), as well as the drought index, this study comprehensively examined the relationship between ecosystem WUE (WUE=GPP/ET) and drought at the global scale...
