Intergovernmental Panel on Climate Change (IPCC) Tier 1 forest biomass estimates from Earth Observation.

Aboveground biomass density (AGBD) estimates from Earth Observation (EO) can be presented with the consistency standards mandated by United Nations Framework Convention on Climate Change (UNFCCC). This article delivers AGBD estimates, in the format of Intergovernmental Panel on Climate Change (IPCC) Tier 1 values for natural forests, sourced from National Aeronautics and Space Administration's (NASA's) Global Ecosystem Dynamics Investigation (GEDI) and Ice, Cloud and land Elevation Satellite (ICESat-2), and European Space Agency's (ESA's) Climate Change Initiative (CCI). It also provides the underlying classification used by the IPCC as geospatial layers, delineating global forests by ecozones, continents and status (primary, young (≤20 years) and old secondary (>20 years)).

Predictors of Satisfaction in Patients with Knee Osteoarthritis Treated with a Single Injection of Mannitol-Modified Crosslinked Hyaluronate Derivative.

There is a gap between the very positive opinion of patients and doctors regarding knee viscosupplementation (VS) and the contrasting results of controlled studies. The objective of this study was to evaluate the overall satisfaction and predictors of satisfaction with VS in patients with knee osteoarthritis treated with VS. : Post-hoc analysis of a cross-sectional study in patients with knee OA treated with one injection of a mannitol-modified cross-linked HA (HANOX-M-XL).

Brooding duration does not depend on cat predation risk but is related to weather and phenology in the wandering albatross ().

Parental investment increases offspring fitness at the expense of the parent's ability to invest in other offspring. In many animal species, parents guard their offspring after birth. The parental decision over the duration of this period is expected to be triggered by the associated fitness costs and benefits for both offspring and parents.

Human degradation of tropical moist forests is greater than previously estimated.

Tropical forest degradation from selective logging, fire and edge effects is a major driver of carbon and biodiversity loss, with annual rates comparable to those of deforestation. However, its actual extent and long-term impacts remain uncertain at global tropical scale. Here we quantify the magnitude and persistence of multiple types of degradation on forest structure by combining satellite remote sensing data on pantropical moist forest cover changes with estimates of canopy height and biomass from spaceborne light detection and ranging (LiDAR).

A Cross-Sectional Study of Factors Predicting the Duration of the Efficacy of Viscosupplementation in Knee Osteoarthritis.

An advanced radiological stage and obesity are predictive of poorer and shorter responses to viscosupplementation in patients with knee osteoarthritis (OA). Very little is known regarding the impact of other factors such as sport practice, comorbidities, or anatomical features of OA. This study aimed to investigate patients' and OA characteristics associated with the duration of the effectiveness (DE) of viscosupplementation in patients with knee OA.

Inventory of Patient-Reported Outcome Measures Used in the Non-Operative Care of Scoliosis: A Scoping Review.

It is unclear which patient-reported outcome measures (PROMs) can assess non-operative care for scoliosis. Most existing tools aim to assess the effects of surgery. This scoping review aimed to inventory the PROMs used to assess non-operative scoliosis treatment by population and languages.

The Association between Radiographic Features and the Duration of Effectiveness of a Single Injection of Extended-Release Hyaluronic Acid (HANOX-M-XL) in Patients with Knee Osteoarthritis: Preliminary Results of a Prospective Trial.

Background: Advanced radiological stage of knee osteoarthritis (OA) is predictive of poor response to viscosupplementation (VS). To date, the impact of x-ray features on the duration of effectiveness (DE) of VS has not been investigated.

Objectives: To investigate the radiological features associated with DE of VS in patients with knee OA.

Short-term hypoxia does not promote arrhythmia during voluntary apnea.

The presence of bradycardic arrhythmias during volitional apnea at altitude may be caused by chemoreflex activation/sensitization. We investigated whether bradyarrhythmic episodes became prevalent in apnea following short-term hypoxia exposure. Electrocardiograms (ECG; lead II) were collected from 22 low-altitude residents (F = 12; age=25 ± 5 years) at 671 m.

Effect of Hydrocortisone on Mortality and Organ Support in Patients With Severe COVID-19: The REMAP-CAP COVID-19 Corticosteroid Domain Randomized Clinical Trial.

Importance: Evidence regarding corticosteroid use for severe coronavirus disease 2019 (COVID-19) is limited.

Objective: To determine whether hydrocortisone improves outcome for patients with severe COVID-19.

Design, Setting, And Participants: An ongoing adaptive platform trial testing multiple interventions within multiple therapeutic domains, for example, antiviral agents, corticosteroids, or immunoglobulin.

Predictive factors of mortality in patients treated with tocilizumab for acute respiratory distress syndrome related to coronavirus disease 2019 (COVID-19).

COVID-19 patients (n = 34) suffering from ARDS were treated with tocilizumab (TCZ). Outcome was classified in two groups: "Death" and "Recovery". Predictive factors of mortality were studied.

Tunable High Spatio-Spectral Purity Undulator Radiation from a Transported Laser Plasma Accelerated Electron Beam.

Undulator based synchrotron light sources and Free Electron Lasers (FELs) are valuable modern probes of matter with high temporal and spatial resolution. Laser Plasma Accelerators (LPAs), delivering GeV electron beams in few centimeters, are good candidates for future compact light sources. However the barriers set by the large energy spread, divergence and shot-to-shot fluctuations require a specific transport line, to shape the electron beam phase space for achieving ultrashort undulator synchrotron radiation suitable for users and even for achieving FEL amplification.

Vulnerability of the agricultural sector to climate change: The development of a pan-tropical Climate Risk Vulnerability Assessment to inform sub-national decision making.

As climate change continues to exert increasing pressure upon the livelihoods and agricultural sector of many developing and developed nations, a need exists to understand and prioritise at the sub national scale which areas and communities are most vulnerable. The purpose of this study is to develop a robust, rigorous and replicable methodology that is flexible to data limitations and spatially prioritizes the vulnerability of agriculture and rural livelihoods to climate change. We have applied the methodology in Vietnam, Uganda and Nicaragua, three contrasting developing countries that are particularly threatened by climate change.

Mislocalization of sensory information in people with chronic low back pain: a preliminary investigation.

Objectives: The purpose of this study was to establish if people with chronic low back pain (CLBP) demonstrate impairments in the ability to localize sensory information delivered to the back more than pain-free controls and determine whether any sensory abnormalities are related to pain-related variables.

Methods: Vision was occluded and participants were stimulated using light touch or pinprick over a number of body areas in random order. To assess for mislocalizations participants were asked to nominate the location of each stimulus in reference to a marked body chart.

Bicistronic lentiviral vector corrects beta-hexosaminidase deficiency in transduced and cross-corrected human Sandhoff fibroblasts.

Sandhoff disease is an autosomal recessive neurodegenerative disease characterized by a GM2 ganglioside intralysosomal accumulation. It is due to mutations in the beta-hexosaminidases beta-chain gene, resulting in a beta-hexosaminidases A (alphabeta) and B (betabeta) deficiency. Mono and bicistronic lentiviral vectors containing the HEXA or/and HEXB cDNAs were constructed and tested on human Sandhoff fibroblasts.

Widespread distribution of beta-hexosaminidase activity in the brain of a Sandhoff mouse model after coinjection of adenoviral vector and mannitol.

Sandhoff disease is a severe inherited neurodegenerative disorder resulting from deficiency of the beta-subunit of hexosaminidases A and B, lysosomal hydrolases involved in the degradation of G(M2) ganglioside and related metabolites. Currently, there is no viable treatment for the disease. Here, we show that adenovirus-mediated transfer of the beta-subunit of beta-hexosaminidase restored Hex A and Hex B activity after infection of Sandhoff fibroblasts.

The NMR contrast agent Gd-25 DTPA-MAb 19-9 or 73-3 ([Gd] 17 mumole/kg, [MAb] 60 microM) was injected into nude mice bearing human colon adenocarcinoma (SW948).

Mathematical morphology for automatic detection of brain lesions at magnetic resonance imaging.

An original method of image analysis has been developed, using 'mathematical morphology', in order to detect brain tumors at magnetic resonance imaging of the head following injection of gadolinium-DPTA. The main steps of the analysis are as follows: 1) Spatial reduction by automatic determination of a region of interest, 2) elimination of noise by morphologic filtering (increasing alternate closing-opening sequence), 3) localization of tumor by searching for r-h maxima, and 4) extraction of tumor contours using three-dimensional structuring elements. The preliminary results of this automatic and robust method encourage further studies of the potential of tissue analysis as an aid to tumor diagnosis.
