Crassulacean acid metabolism (CAM) is a specialized mode of photosynthesis that features nocturnal CO2 uptake, facilitates increased water-use efficiency (WUE), and enables CAM plants to inhabit water-limited environments such as semi-arid deserts or seasonally dry forests. Human population growth and global climate change now present challenges for agricultural production systems to increase f...
Calmodulin (CaM) regulates gating of several types of ion channels but has not been implicated in channel assembly or trafficking. For the SK4/IK1 K+ channel, CaM bound to the proximal C terminus ("Ct1 " domain) acts as the Ca2+ sensor. We now show that CaM interacting with the C terminus of SK4 also controls channel assembly and surface expression. In transfected cells, removing free CaM by ov...
Mind model consciousness and memory (CAM) is a biologically inspired mind model, which is a general framework for human-level intelligent systems. Consciousness module plays very important role in mind model CAM. This paper presents architecture of machine consciousness containing awareness, attention, motivation, metacognition, introspective learning and global work‐ space modules. The propose...
Understanding conformational changes are important when studying a protein such as calmodulin (CaM), which activates various target enzymes and regulates numerous physiological functions. CaM is a highly flexible protein that can transitorily adopt various conformations. A quartz crystal microbalance with dissipation (QCM-D) sensor was used to study binding-induced conformational changes of sur...
This paper presents how to manage Virtual Organizations to enable efficient collaboration and/or cooperation as a result of a flexible and parametrical model. The CAM (Collaborative/Cooperative Awareness Management) model promotes collaboration around resources-sharing infrastructures, endorsing interaction by means of a set of rules. This model focuses on responding to specific demanding circu...
recently, as the result of the development in modern imaging, computerized three dimensional data processing and advanced engineering techniques, an prosthesis that match the skeletal anatomy can be accurately designed from computer aided design (cad) technique and the physical model of prosthesis or skull replica can be produced through rapid prototyping (rp), rapid tooling (rt), and computer ...
Abstract Background: Children suffering from cancer frequently use complementary and alternative medicine (CAM). Most of people do not disclose using CAM to their physicians as they fear to be blamed or prohibited using them. Some of these products may interfere with the conventional remedies. The aim of this study was to investigate the frequency and characteristics of CAM ...
To investigate the function of calmodulin (CaM) in the mitotic apparatus, the effect of microinjected CaM and chemically modified CaMs on nocodazole-induced depolymerization of spindle microtubules was examined. When metaphase PtK1 cells were microinjected with CaM or a CaM-TRITC conjugate, kinetochore microtubules (kMTs) were protected from the effect of nocodazole. The ability of microinjecte...
This paper describes a computationally efficient framework for uncertainty studies in global and regional climate change. In this framework, the Massachusetts Institute of Technology (MIT) Integrated Global System Model (IGSM), an integrated assessment model that couples an Earth system model of intermediate complexity to a human activity model, is linked to the National Center for Atmospheric ...
RATIONALE Calmodulin (CaM) associates with cardiac ryanodine receptor type-2 (RyR2) as an important regulator. Defective CaM-RyR2 interaction may occur in heart failure, cardiac hypertrophy, and catecholaminergic polymorphic ventricular tachycardia. However, the in situ binding properties for CaM-RyR2 are unknown. OBJECTIVE We sought to measure the in situ binding affinity and kinetics for Ca...
