Acylation of adenylyl cyclase catalyst is important for enzymic activity.
Incubation of human thrombocytes in the presence of [3H]palmitic acid leads to incorporation of this fatty acid into the alpha subunit of Gs as described [Linder et al., Proc. Natl. Acad. Sci. USA 90 (1993) 3675-3679; Degtyarev et al., Biochemistry 32 (1993) 8057-8061] but also into the catalyst of adenylyl cyclase which has not been recognized before. Treatment of labeled membranes with hydrox...
متن کاملNatural Biopolymers is an Efficient Catalyst for the Synthesis of 1,3,5-Trisubstituted Pyrazoles
Cellulose sulfuric acid is an efficient metal-free catalyst for the synthesis of 1,3,5-trisubstituted pyrazoles via the condensation of 1,3-diketones and hydrazines. The reaction was carried out in Solvent-free condition at room temperature and the products were isolated in good to excellent yields. Mild reaction conditions, as well as ease of operation and workup are some advantages of the pro...
متن کاملWhen size is not important any more
Wireless phone companies, especially with number portability, sell a product that is less and less different, that is to say, a commodity. That is the reason scale economies play a very important role in this market. Given that it is not possible to make a large margin on the service that they offer, companies must focus their strategies on saving costs. Moreover, the more clients a company has...
متن کاملBrain function - not size - is important
Some incidental findings on cranial imaging may render every one speechless. Brain plasticity in childhood and slow expansion of arachnoid cyst may be possible explanations of the discordance between the clinical and radiological findings. Here, we presented an asymptomatic, incidentally detected arachnoid cyst accompanied by compression of most parts of brain, displacing the motor cortex to th...
متن کاملImaging liver metastases—size is important
All metastases start out small, and treatment is more likely to be effective if the disease is detected at an early stage, so the current focus of imaging is to improve our ability to find small lesions. Sixty years ago, the most effective instrument for detecting liver metastases was the surgeon’s hand during laparotomy. J C Goligher, a former colleague in Leeds, followed up about 700 patients...
