Glucagon is a 29-amino-acid peptide released from the α-cells of the islet of Langerhans, which has a key role in glucose homeostasis. Glucagon action is transduced by the class B G-protein-coupled glucagon receptor (GCGR), which is located on liver, kidney, intestinal smooth muscle, brain, adipose tissue, heart and pancreas cells, and this receptor has(More)
An integrated active optical, and passive thermal infrared sensing system was deployed on a low-level aircraft (50 m AGL) to record and map the simple ratio (SR) index and canopy temperature of a 230 ha cotton field. The SR map was found to closely resemble that created by a RapidEye satellite image, and the canopy temperature map yielded values consistent(More)
G-protein coupled receptors (GPCRs) are important therapeutic targets since more than 40% of the drugs on the market exert their action through these proteins. To decipher the molecular mechanisms of activation and signaling, GPCRs often need to be isolated and reconstituted from a detergent-solubilized state into a well-defined and controllable lipid model(More)
Nitrogen (N) fertilization is crucial for the growth and development of wheat crops, and yet increased use of N can also result in increased stripe rust severity. Stripe rust infection and N deficiency both cause changes in foliar physiological activity and reduction in plant pigments that result in chlorosis. Furthermore, stripe rust produce pustules on(More)
The ability to identify areas of pasture that are more likely to support damaging levels of the soil-borne, redheaded cockchafer (Adoryphorus couloni) (Burmeister) (RHC) would allow farmers to target expensive control measures. This study explored soil properties, measured via electromagnetic surveys (EM38), pasture biomass via active optical sensors(More)
The amount of photosynthetically active radiation (PAR, 0.4–0.7 μm) absorbed by plants for photosynthesis relative to incident radiation is defined as the fraction of absorbed photosynthetically active radiation (fAPAR). This is an important variable in both plant biomass production and plant growth modeling. This study investigates the application of a(More)
Traumatic tetraplegia often affects healthy young men. The medullary lesion is located at C6 in 75% of cases. The author on the basis of 20 years of experience believes it possible to improve independence and life quality by surgical procedures such as tendon transfers, which are the most often used, for restoring two important functions: active elbow(More)
Palmar fascia from six men with Dupuytren's contracture has been grown in tissue-culture and examined cytogenetically; and in three of these cases skin was also studied. Four of the six cases showed mosaicism, but only in cultures of the fascia; the mosaicism was therefore unlikely to be an artefact. Since the abnormalities were inconsistent and absent from(More)
