Physical properties and biological/odontogenic effects of an experimentally developed fast-setting α-tricalcium phosphate-based pulp capping material
submitted by jirechajir 12 minutes ago - Topic: Health
Recently, fast-setting α-tricalcium-phosphate (TCP) cement was developed for use in the pulp capping process. The aim of this study was to investigate the physical properties and biological effects of α-TCP cement in comparison with mineral trioxide aggregate (MTA). We measured the setting time, pH values, compressive strength, and solubility of the two materials. We evaluated biocompatibilit...



Comparison of Complement Activity in Adult and Preterm Sheep Serum
submitted by tetas2095 13 minutes ago - Topic: Health
Functional complement activity is routinely measured utilizing rabbit antibody-sensitized sheep erythrocytes. Due to complement inhibitor expression on erythrocytes, the development of an alternative method to measure complement function in sheep serum was required. Method of studySeveral species of target erythrocyte and sensitizing antibody were investigated for improved measurement of comple...

Cellular Inhibitors of Apoptosis Proteins cIAP1 and cIAP2 are Increased after Labour in Foetal Membranes and Myometrium and are Essential for TNF-α-Induced Expression of Pro-Labour Mediators
submitted by tetas2095 13 minutes ago - Topic: Health
Inflammation is commonly associated with preterm birth. In non-gestational tissues, the cellular inhibitor of apoptosis protein (cIAP) 1 and 2, independent of their role in apoptosis, have emerged as important regulators of inflammation. There is, however, no data on the effect of human labour on the expression of cIAPs in human gestational tissues, or on their role in modulating TNF-α induced...

Latent TGF-β1 is Compartmentalized Between Blood and Seminal Plasma of HIV-Positive Men and Its Activation in Semen is Negatively Correlated with Viral Load and Immune Activation
submitted by tetas2095 14 minutes ago - Topic: Health
Semen is the primary medium for sexual transmission of HIV-1 and contains high concentrations of TGF-β1, but its role in regulating HIV-mediated immune activation is unclear. Method of StudyTGF-β1 and sCD14 were compared in blood plasma (BP) and seminal plasma (SP) from HIV-uninfected and infected, antiretroviral therapy (ART)-naive and ART-treated men and in THP-1 cells following exposure to...

Effects of Set-aside Conservation Practices on Bird Community Structure within an Intensive Agricultural Landscape
submitted by onnittiholl 15 minutes ago - Topic: Biology
Creating and restoring patches of noncrop early-succession vegetation within agricultural landscapes may mitigate grassland bird population declines caused by agricultural land use and intensification. Achieving this goal requires an ability to balance avian benefits with agronomics, which may be facilitated by understanding how bird communities respond to various conservation practices. We eva...



Sugar flux through the flight muscles of hovering vertebrate nectarivores: a review
submitted by safeo 16 minutes ago - Topic: Health
In most vertebrates, uptake and oxidation of circulating sugars by locomotor muscles rises with increasing exercise intensity. However, uptake rate by muscle plateaus at moderate aerobic exercise intensities and intracellular fuels dominate at oxygen consumption rates of 50 % of maximum or more. Further, uptake and oxidation of circulating fructose by muscle is negligible. In contrast, humming...

Oxygen removal from water versus arterial oxygen delivery: calibrating the Fick equation in Pacific salmon
submitted by safeo 16 minutes ago - Topic: Health
While it is well known that O2 is directly removed from the water by skin and gill tissues of fish, the mismatch between O2 removal from water (O2 uptake; (dot{V}{text{O}}_{ 2})) and the O2 delivered to tissues by the primary circulation (O2 consumption; (dot{V}{text{aO}}_{ 2})) has never been measured directly. Using data from four recent studies that simultaneously measured (dot{V}{text{O}}_{...


Central glucose sensing
submitted by omanca 18 minutes ago - Topic: Health
Since concentrations of blood glucose represent an important aspect of systemic energy homeostasis, we postulate that fluctuation of glycemia must not be only detected by pancreatic β-cells, and central neuron system (CNS) could monitor and regulate the plasma glucose levels in some stilled undefined mechanisms. In this review, we will summarize recent progress focused in the identification an...

Faut-il faire maigrir un patient obèse avant un acte de chirurgie lourde ?
submitted by omanca 18 minutes ago - Topic: Health
L’obésité est un facteur de risque connu de morbi-mortalité. Au contraire, après chirurgie, le surpoids et l’obésité commune (grade 1 et 2) sont associés à une diminution du risque de mortalité postopératoire. Ce constat appelé obesity paradox est établi en chirurgie générale comme en chirurgie cardiovasculaire. En revanche, l’obésité est associée à une augmentation du ...


Coexistence of productive and non-productive populations by fluctuation-driven spatio-temporal patterns
submitted by nabliorajo3119 20 minutes ago - Topic: Biology
Cooperative interactions, their stability and evolution, provide an interesting context in which to study the interface between cellular and population levels of organization. Here we study a public goods model relevant to microorganism populations actively extracting a growth resource from their environment. Cells can display one of two phenotypes—a productive phenotype that extracts the res...

The State of Israel is preparing to transfer legal responsibility for mental- health care from the government to the country's four competing, nonprofit health-plans. A prominent feature of this reform is the introduction of managed care into the mental-health system. This change will likely affect the service delivery patterns and care practices of zprofessional caregivers in mental-health ser...

On the magnitude and dynamics of eddy covariance system residual energy (energy balance closure error) in subsurface drip-irrigated maize field during growing and non-growing (dormant) seasons
submitted by takedake92 27 minutes ago - Topic: Agriculture
We investigated the magnitude and dynamics of the eddy covariance system (ECS) residual energy (energy balance closure error) for a subsurface drip-irrigated maize (Zea mays L.) field in 2005 and 2006 growing and non-growing (dormant) seasons. The corrections for coordinate rotation, oxygen, frequency, and Webb–Pearman–Leuning corrections improved the slope of the total convective energy (l...
