Understanding behavioral strategies employed by animals to maximize fitness in the face of environmental heterogeneity, variability, and uncertainty is a central aim of animal ecology. Flexibility in behavior may be key to how animals respond to climate and environmental change. Using a mechanistic modeling framework for simultaneously quantifying the effects of habitat preference and intrinsic movement on space use at the landscape scale, we investigate how movement and habitat selection vary among individuals and years in response to forage quality-quantity tradeoffs, environmental conditions, and variable annual climate...

PURPOSE: D-dopachrome tautomerase (MIF-2 or DDT) is a member of the macrophage migration inhibitory factor (MIF) superfamily and a close structural homolog to MIF. Circulating MIF-2 has been described to be elevated in patients suffering from sepsis, severe burn injury and after surgery. We sought to evaluate the prognostic value of MIF-2 in critically ill patients. METHODS: A total of 72 patients were studied upon admission to the medical intensive care unit (ICU)...

Burn is the most common pediatric injuries all over the world. The aim of this study was to study the epidemiology of burn in under 15-year-old Iranian children by applying a systematic review. The related articles published before 2016 have been gathered from international databases by using the keywords in term of pediatric burns such as ScienceDirect, PubMed, Iranmedex, Google Scholar, Embase, Magiran, and SID. The checklists of STROBE have been applied to evaluate the quality of the reviewed data. A total of 35 relevant studies were extracted and evaluated...

To evaluate the edema volume and leukocyte, platelet, and fibrinogen count of peripheral burn in an animal model. The back left leg of Rattus norvegicus (experimental group) was placed in water at 60 °C for 60 seconds or at room temperature (control group). An analysis was carried out before and after the induced burn (at 4, 8, 12, and 24 h). The edema volume was determined by an orthogonal photo, the leukocyte and platelet counts were determined using automated equipment, and the fibrinogen count was determined using the gravimetric method...

Burn infection is a serious problem that delays wound healing and leads to death. Curcumin (Cur) has been shown to exhibit antioxidant, anti-inflammatory, antimicrobial and anticarcinogenic activity. However, its instability, extremely low aqueous solubility and bioavailability in physiological fluids may make it difficult to maintain local Cur concentrations above the minimum inhibitory concentration for burn infection treatment. The objective of this study was to construct complexes of Cur/gelatin microspheres (GMs) and porous collagen (Coll)-cellulose nanocrystals (CNCs) composite scaffolds for full-thickness burn infection treatment...

Complex, full-thickness soft tissue defects secondary to large burns, trauma and war-related injuries continue to challenge reconstructive surgeons. To achieve positive surgical outcomes in these patient populations, novel approaches are needed to restore the functional, protective and aesthetic properties of skin. Herein, we provide the first report describing the staged use of a dermal regenerate template (DRT) with a spray-on epidermal regenerative modality (spray skin) in addition to autologous split-thickness skin grafting (STSG) in non-burn trauma and compare these results with those of patients treated with DRT and STSG alone...

PURPOSE: There is a paucity of research on reducing dressing adherence. This is partly due to lack of an in vitro model, recreating the clinical variability of wounds. Previously we described an in vitro gelatin model to evaluate adherence in a standardized manner. We present evaluation of strategies to reduce adherence in six dressings. PROCEDURES: Dressing materials used were: PET (Control), fine mesh gauze coated in bismuth and petroleum jelly (BIS), nanocrystalline silver (NS), wide mesh polyester coated in polysporin ointment (WM), fine mesh cellulose acetate coated in polysporin ointment (FM), and soft silicone mesh (SIL)...

We examine three variations of the regularization methods for response-adaptive randomization (RAR) and compare their operating characteristics. A power transformation (PT) is applied to refine the randomization probability. The clip method is used to bound the randomization probability within specified limits. A burn-in period of equal randomization (ER) can be added before adaptive randomization (AR). For each method, more patients are assigned to the superior arm and overall response rate increase as the scheme approximates simple AR, while statistical power increases as it approximates ER...

Wildfire is a natural disturbance, though elemental losses and changes that occur during combustion and post-fire erosion can have long-term impacts on soil properties, ecosystem productivity, and watershed condition. Here we evaluate the potential of forest residue-based materials to rehabilitate burned soils. We compare soil nutrient and water availability, and plant recovery after application of 37 t ha(-1) of wood mulch, 20 t ha(-1) of biochar, and the combination of the two amendments with untreated, burned soils...

To evaluate the role of biomass burning emissions, and in particular of residential wood heating, as a result of the economic recession in Greece, carbon monoxide (CO) atmospheric concentrations from five (5) stations of the National Air Pollution Monitoring Network in Athens, spanning the period 2000-2015, in conjunction with black carbon (BC) concentrations from the NOA (National Observatory of Athens) station at Thissio were analysed. The contribution of the different sources to the diurnal cycle of these two pollutants is clear, resulting to a morning peak, mainly due to traffic, and a late evening peak attributed both to fossil fuel (traffic plus central heating) and biomass combustion...

The Notch pathway ligand Delta-like 4 (Dll4) functions as an antiangiogenic factor, inhibiting vascular endothelial growth factor (VEGF)-induced angiogenesis. This function is documented in tumor and embryonic vasculature. However, its implication in burn wounds remains unexplored. Our objective was to explore the involvement of the Notch in the healing of zone of stasis burns. We hypothesized that anti-Dll4 therapy would prevent progressive necrosis in the stasis zone by promoting angiogenesis. Burns were created in 21 rats using the comb burn model...

BACKGROUND: The deficit of donor sites in major burns over 50% of the total body surface area has necessitated the application of methods besides traditional meshed autografting to achieve definitive skin cover. The Meek micrografting technique was introduced at this hospital in 2011, especially in the absence of a reliable source of deceased donor allograft skin. The purpose of this study was to evaluate this strategy with reference to its technical execution, efficacy and indications in the context of major paediatric burn surgery...

BACKGROUND: Approximately 18-20% of all human breast cancers have overexpressed human epidermal growth factor receptor 2 (HER2). Standard clinical practice is to treat only overexpressed HER2 (HER2+) cancers with targeted anti-HER2 therapies. However, recent analyses of clinical trial data have found evidence that HER2-targeted therapies may benefit a sub-group of breast cancer patients with non-overexpressed HER2. This suggests that measurement of other biological factors associated with HER2 cancer, such as HER2 signaling pathway activity, should be considered as an alternative means of identifying patients eligible for HER2 therapies...

OBJECTIVE Thalamotomy of the ventral intermediate nucleus (VIM) is effective in alleviating medication-resistant tremor in patients with essential tremor (ET) and Parkinson's disease (PD). MR-guided focused ultrasound (MRgFUS) is an innovative technology that enables noninvasive thalamotomy via thermal ablation. METHODS Patients with severe medication-resistant tremor underwent unilateral VIM thalamotomy using MRgFUS. Effects on tremor were evaluated using the Clinical Rating Scale for Tremor (CRST) in patients with ET and by the motor part of the Unified Parkinson's Disease Rating Scale (UPDRS) in patients with PD and ET-PD (defined as patients with ET who developed PD many years later)...
