Diaphragm Muscle Sarcopenia in Aging Mice
submitted by omolfansad 31 minutes ago - Topic: Health
Sarcopenia, defined as muscle weakness and fiber atrophy, of respiratory muscles such as the diaphragm (DIAm) has not been well characterized. The DIAm is the main inspiratory muscle and knowledge of DIAm sarcopenia is important for establishing the effects of aging on respiratory function. We hy...



Silver nanoparticles (AgNPs) cause degeneration of cytoskeleton and disrupt synaptic machinery of cultured cortical neurons
submitted by kinwelkens 32 minutes ago - Topic: Health
Silver nanoparticles (AgNPs), owing to their effective antimicrobial properties, are being widely used in a broad range of applications. These include, but are not limited to, antibacterial materials, the textile industry, cosmetics, coatings of various household appliances and medical devices. D...

Simian Foamy Virus in Non-Human Primates and Cross-Species Transmission to Humans in Gabon: An Emerging Zoonotic Disease in Central Africa?
submitted by vejoykamor 32 minutes ago - Topic: Health
It is now known that all human retroviruses have a non-human primate counterpart. It has been reported that the presence of these retroviruses in humans is the result of interspecies transmission. Several authors have described the passage of a simian retrovirus, simian foamy virus (SFV), from pr...

The Role of Bacterial Chaperones in the Circulative Transmission of Plant Viruses by Insect Vectors
submitted by vejoykamor 32 minutes ago - Topic: Health
Persistent circulative transmission of plant viruses involves complex interactions between the transmitted virus and its insect vector. Several studies have shown that insect vector proteins are involved in the passage and the transmission of the virus. Interestingly, proteins expressed by bacter...

A simple and rapid capillary chemiluminescence immunoassay for quantitatively detecting human serum HBsAg
submitted by liexys94 32 minutes ago - Topic: Biology
The quantitative measurement of serum hepatitis B surface antigen (HBsAg) is important for monitoring anti-hepatitis B virus (HBV) therapy and evaluating the safety of blood products or blood transfusion. This study is aimed at generating and evaluating a capillary-based chemiluminescence immunoa...



Characterization of a trifunctional fatty acid desaturase from oleaginous filamentous fungus Mortierella alpina 1S-4 using a yeast expression system
submitted by pp92558 33 minutes ago - Topic: Biology
A ω3-fatty acid desaturase gene (maw3) which is involved in biosynthesis of n-3 polyunsaturated fatty acids (PUFAs) was previously isolated from Mortierella alpina 1S-4. In this report, we investigated the products of MAW3 catalyzing reaction with endogenous and exogenous fatty acids in the yeas...

Traitement des brides de la maladie de Dupuytren par la collagénase injectable
submitted by doneildeoz 33 minutes ago - Topic: Health
La maladie de Dupuytren (MD) est une affection de l’aponévrose palmaire provoquant l’apparition de brides pathologiques de collagène qui aboutissent progressivement à une rétraction digitale. Ces rétractions entraînent à terme une perte de fonction au niveau de la main avec un véritab...

Partnerships and Sustainable Development: the Lessons Learned from International Biodiversity Governance
submitted by sflonniry2 40 minutes ago - Topic: Environment
Over the past decade, partnerships have increasingly become a popular governance instrument for sustainable development. This article aims to improve our understanding of this instrument, and its contributions to and consequences for international sustainable development politics, by providing th...

Models of Representation and Participation in Model Forests: Dilemmas and Implications for Networked Forms of Environmental Governance Involving Indigenous People
submitted by sflonniry2 40 minutes ago - Topic: Environment
Our study of two Model Forests illustrates the complex nature of representation in governance networks, in which different traditions of governance, persistent political disagreement and historical adversaries work together to achieve some goal. Using Pitkin's (1967) models of representation, we ...

Adaptive Capacity: Tensions across Scales
submitted by sflonniry2 40 minutes ago - Topic: Environment
Climate variability and climate change impacts on hydrological conditions prescribe the need to better understand favourable conditions for developing and mobilising adaptive capacity. This paper presents new cases to the body of evidence on adaptive capacity in the context of institutional arran...

High dose of extracellular ATP switched autophagy to apoptosis in anchorage-dependent and anchorage-independent hepatoma cells
submitted by ktimp 41 minutes ago - Topic: Biology
Extracellular adenosine triphosphate (eATP) transduces purinergic signal and plays an important regulatory role in many biological processes, including tumor cell growth and cell death. A large amount of eATP exists in the fast-growing tumor center and inflammatory tumor microenvironment. Tumor c...

Spatial distribution and habitat characterization of schistosomiasis host snails in lake and land habitats of western Kenya
submitted by slabadon 41 minutes ago - Topic: Geography
Intermediate host snails of schistosomiasis were surveyed in this study to determine their abundance and distribution in the lake and land aquatic habitats of Lake Victoria basin of Kenya. Several sites were sampled at eight locations, both in the lake and on the land. The habitat and/or vegetati...

Assessment of water quality, macroinvertebrate biomass and primary productivity of small water bodies for increased fish production in the Lake Victoria basin, Kenya
submitted by slabadon 41 minutes ago - Topic: Geography
This study investigated the suitability of small water bodies (SWBs) in the Lake Victoria basin, between November 2010 and October 2011 for increased food production through aquaculture. Sampling sites were stratified in terms of water availability and altitude. Low-altitude sites were represente...

Anthropogenic and climatic influences over the past three centuries on characteristics of an Adirondack lake, Eastern North America
submitted by slabadon 41 minutes ago - Topic: Geography
Fourth Lake is a drainage lake at 43°N, 74°W, from which a 37-cm long mud-water interface core was recovered. 210Pb dating indicates the core spans ≈340 years, from the Little Ice Age through modern global warming. Diatom accumulation responds to anthropogenic watershed disturbances, declini...

Spatio-temporal variation of gross CO2 and CH4 diffusive emissions from Australian reservoirs and natural aquatic ecosystems, and estimation of net reservoir emissions
submitted by slabadon 41 minutes ago - Topic: Geography
Carbon dioxide (CO2) and methane (CH4) diffusive emissions were measured during two field surveys in Queensland and Tasmania, Australia, using the floating chamber method. Bubbling and degassing emissions in 2010 were estimated in Koombooloomba Dam reservoir using only inverted funnels and gas co...
