Terson syndrome in subarachnoid hemorrhage, intracerebral hemorrhage, and traumatic brain injury
submitted by beaanso32 5 minutes ago - Topic: Health
This prospective trial was designed to evaluate the incidence of Terson syndrome in patients suffering from subarachnoid hemorrhage, intracerebral hemorrhage, or traumatic brain injury and whether consequences necessarily derive from the intraocular hemorrhage itself. Two ophthalmologic examinations were performed to identify patients with Terson syndrome. Data on initial Glasgow Coma Scale, Hu...



Extremely minimally invasive”: recent advances in nanotechnology research and future applications in neurosurgery
submitted by beaanso32 5 minutes ago - Topic: Health
The term “nanotechnology” refers to the development of materials and devices that have been designed with specific properties at the nanometer scale (10−9 m), usually being less than 100 nm in size. Recent advances in nanotechnology have promised to enable visualization and intervention at the subcellular level, and its incorporation to future medical therapeutics is expected to bring n...

Global analysis of saliva as a source of bacterial genes for insights into human population structure and migration studies
submitted by schinsaz 6 minutes ago - Topic: Biology
The genetic diversity of the human microbiome holds great potential for shedding light on the history of our ancestors. Helicobacter pylori is the most prominent example as its analysis allowed a fine-scale resolution of past migration patterns including some that could not be distinguished using human genetic markers. However studies of H. pylori require stomach biopsies, which severely limits...

Aquaporin 4-Dependent expression of glial fibrillary acidic protein and tenascin-C in activated astrocytes in stab wound mouse brain and in primary culture
submitted by jspinci 7 minutes ago - Topic: Health
We previously reported that aquaporin 4 (AQP4) has a neuroimmunological function via astrocytes and microglial cells involving osteopontin. AQP4 is a water channel localized in the endofoot of astrocytes in the brain, and its expression is upregulated after a stab wound to the mouse brain or the injection of methylmercury in common marmosets. In this study, the correlation between the expressio...

Economic Valuation of Land Uses in Oudomxay Province, Lao PDR: Can REDD+ be Effective in Maintaining Forests?
submitted by omoloa 10 minutes ago - Topic: Geography
The rapid economic growth in Lao PDR over the last two decades has been driven by the natural resource sectors and commercialization in the agriculture sector. Rural landscapes are being transformed over the past decade from land use mosaics of subsistence and smallholder farms to large-scale plantations dominated by a few commercial crops. The capacity of these commercial agriculture plantatio...



Cardiopulmonary exercise testing in systolic heart failure in 2014: the evolving prognostic role
submitted by colthrapi 25 minutes ago - Topic: Health
The relationship between exercise capacity, as assessed by peak oxygen consumption, and outcome is well established in heart failure (HF), but the predictive value of cardiopulmonary exercise testing (CPET) has been recently questioned, for two main reasons. First, the decisional power of CPET in the selection of heart transplantation candidates has diminished, since newer therapeutic options a...

Uniform predation risk in nature: common, inconspicuous, and a source of error to predation risk experiments
submitted by rodasistros 27 minutes ago - Topic: Biology
Previous studies indicate that when predation risk is uniform across habitats, foragers concentrate their exploitation in fewer patches. Although uniform predation risk may seem rare in nature, some scenarios might cause it. Testing all scenarios in a single experiment is unfeasible; therefore, we developed a model that points whether concentration of exploitation in specific habitats due to un...


Nitrogen and residual organic matter removal from anaerobic reactor effluent in a fixed-bed reactor with biogas for denitrification
submitted by omoloa 35 minutes ago - Topic: Biology
This paper describes an evaluation of a fixed-bed aerobic/anoxic reactor (AAFBR) for the post-treatment of effluent from an up-flow anaerobic sludge blanket (UASB) reactor treating domestic sewage. This is a new reactor configuration comprising an upper aerobic nitrification chamber fed with the effluent from the UASB reactor. The nitrified effluent flows downwards to an anoxic chamber that is ...

Spontaneous local alpha oscillations predict motion-induced blindness
submitted by oenat 37 minutes ago - Topic: Health
Bistable visual illusions are well suited for exploring the neuronal states of the brain underlying changes in perception. In this study, we investigated oscillatory activity associated with ‘motion-induced blindness’ (MIB), which denotes the perceptual disappearance of salient target stimuli when a moving pattern is superimposed on them (Bonneh et al., ). We applied an MIB paradigm in whi...


Antioxidant plasticity and thermal sensitivity in four types of Symbiodinium sp
submitted by chonkezano 50 minutes ago - Topic: Biology
Warmer than average summer sea surface temperature is one of the main drivers for coral bleaching, which describes the loss of endosymbiotic dinoflagellates (genus: Symbiodinium) in reef-building corals. Past research has established that oxidative stress in the symbiont plays an important part in the bleaching cascade. Corals hosting different genotypes of Symbiodinium may have varying thermal...

The Eurasian genes of the 2009 pandemic influenza virus: an integrative perspective on their conveyance to and assimilation in America
submitted by chorlisd88 1 hour ago - Topic: Biology
The formation of pandemic influenza genotypes varied phylogeographically and ecophylogenetically throughout their fully recognized recent 100-years natural history, involving consistently avian plus human genes, and at times swine genes. The last four traceable pandemic strains (PSs) included two American H1N1 viruses with genomes predominantly containing swine genes, of which at least one geno...


Can We Measure the Heel Bump? Radiographic Evaluation of Haglund's Deformity
submitted by nec 1 hour ago - Topic: Health
Haglund's deformity is a symptomatic posterosuperior deformity of the heel. The lateral radiograph of the ankle will show a prominent, large, posterosuperior part of the calcaneus, which can be measured using the Fowler and Philips angle (FPA, the angle between the posterior and plantar surface of the calcaneus) and the calcaneal pitch angle (CPA, the angle between the sole of the foot and the ...

Free and Pedicled Flaps for Reconstruction of the Weightbearing Sole of the Foot: A Comparative Analysis of Functional Results
submitted by nec 1 hour ago - Topic: Health
Reconstruction of the weightbearing sole of the foot is complex and requires soft tissue that is resistant to weight, pressure, and shear stress. Despite a variety of flap types and techniques, it is still challenging to meet these demands. The present retrospective study included 21 patients after reconstruction of plantar tissue defects from 2001 to 201The outcome was evaluated using the lowe...

Spectrometric analysis and scanning electronic microscopy of two pleural plaques from mediaeval Portuguese period
submitted by tokeyoaden 1 hour ago - Topic: Health
During an archaeological excavation at a mediaeval monastery (Flor da Rosa, Crato, Portugal), a skeleton of a adult woman was found with two calcifications in the thoracic cage. The location and the macroscopic analysis of the calcifications allowed them to be assigned as pleural plaques. Spectrometric analysis and scanning electronic microscopy enabled to establish that it originated with an i...
