青霉素或者直接地通过促进细胞分裂和细胞延长,或者通过某些间接的方式迅速地促使秧苗生长。这种直接的作用似乎是青霉素通过提供-sH基改变细胞内-sH基的含量,因为青霉素是一种半胱氨酸——一种含硫氨基酸的衍生物。因此,改变s-H和s-s... 详细信息

青霉素或者直接地通过促进细胞分裂和细胞延长,或者通过某些间接的方式迅速地促使秧苗生长。这种直接的作用似乎是青霉素通过提供-sH基改变细胞内-sH基的含量,因为青霉素是一种半胱氨酸——一种含硫氨基酸的衍生物。因此,改变s-H和s-s的比例在细胞分裂和细胞延长中具有重要的意义.也已经证明,通过减少s-s桥的数量,s-H含量的增加将在纵的方向增加细胞壁的伸展性,以及在不同的有丝分裂时期s-s/s-H的商发生改变(svensson,1971)。

青霉素在水稻胚乳(Biswas和Mukherji,1979)和向日葵中(purohit,1983a)诱导DNA的合成。DNA的含量直到16小时,以及RNA的含量直到12小时都表现出直线上升。根据DNA和RNA水平增加的时间曲线,Biswas和Mukherji(1979)推断,这些事先于赤霉素的生物合成,以及与半粒种子合成蛋白质的能力有关。青霉素在菊属叶子中把氮的水平从0.82％(对照)增加到1.29％(青霉素400mg/mL),因而增加蛋白质的含量(purohit,1984)。

A typical high-e fficiency solar cell device needs the best lattice matching between different constituent layers to mitigate the open-circuit voltage loss. In the present work, the physical properties of Cds thin films are investigated where films with 100 nm thickness were fabricated on the different types of substrates viz. soda–lime glass, indium-doped tin oxide(ITO)-and fl uorine-doped tin oxide(FTO)-coated glass substrates, and silicon wafer using electron beam evaporation. The X-ray diffraction patterns confirmed that deposited thin films showed cubic phase and had(111) as predominant orientation where the structural parameters were observed to be varied with nature of substrates. The ohmic behaviour of the Cds films was disclosed by current–voltage characteristics, whereas the scanning electron microscopy micrograph revealed the uniform deposition of the Cds films with the presence of round-shaped grains. The elemental analysis confirmed the Cds films deposition where the Cd/s weight percentage ratio was changed with nature of substrates. The direct energy band gap was observed in the 1.63–2.50 eV range for the films grown on different substrates. The investigated properties of thin Cds layers demonstrated that the selection of substrate(in terms of nature) during device fabrication plays a crucial role.

World Journal of Hepatology 2015年第7期7卷 926-941页

Primary biliary cirrhosis(PBC) is an autoimmune, slowly progressive, cholestatic, liver disease characterized by a triad of chronic cholestasis, circulating anti-mitochondrial antibodies(AMA), and characteristic liver biopsy findings of nonsuppurative destructive cholangitis and interlobular bile duct destruction. About 10% of PBC patients, however, lack AMA. A variant, called PBC-autoimmune hepatitis(AIH) overlap, is characterized by the above findings of PBC together with findings of elevated serum alanine aminotransferase, elevated serum immunoglobulin G, and circulating anti-smooth muscle antibodies, with liver biopsy demonstrating periportal or periseptal, lymphocytic, piecemeal necrosis. PBC is hypothesized to be related to environmental exposure in genetically vulnerable individuals. It typically occurs in middle-aged females. Prominent clinical features include fatigue, pruritis, jaundice, xanthomas, osteoporosis, and dyslipidemia. The Mayo Risk score is the most widely used and best prognostic system. Ursodeoxycholic acid is the primary therapy. It works partly by reducing the concentration and injury from relatively toxic bile acids. PBC-AIH overlap syndrome is treated with ursodeoxycholic acid and corticosteroids, especially budesonide. Obeticholic acid and fibrate are promising new, but incompletely tested, therapies. Liver transplantation is the definitive therapy for advanced disease, with about 70% 10-year survival after transplantation. Management of pruritis includes local skin care, dermatologist referral, avoiding potential pruritogens, cholestyramine, and possibly opioid antagonists, sertraline, or rifaximin. Management of osteoporosis includes life-style modifications, administration of calcium and vitamin D, and alendronate. statins are relatively safe to treat the osteopenia associated with PBC. Associated sjogren's syndrome is treated by artificial tears, cyclosporine ophthalmic emulsion to stimulate tear production; and saliva substitutes, c

The electromagnetic interference(EMI) shielding properties of polypyrrole/barium ferrite/tantalum pentoxide nanocomposite were studied in the X-band frequency range from 8.2 GHz to 12.4 GHz. The nanocomposites were chemically synthesized at room temperature and then characterized by various techniques. The dielectric material parameters were calculated based on the experimental scattering parameters using Nicholson–Ross and Weir algorithms. The synthesized nanocomposites demonstrated that the shielding effectiveness up to 50 dB depended upon the dielectric loss and weight fraction of ferrite and Ta2O5in the polymer matrix.
