The structure and function of chloroplast in plant leaves can be affected by acid rain and air pollution. The photosystem II in a plant is considered the primary site where light-induced delayed light emission (DLE) is produced. With the lamina of zijinghua (Bauhinia variegata L.) and soybean (Glycine max (L.) Merr.) as testing models, we studied the effects of artificial acid rain and SO2 on c...
Cloud, being the most vulnerable next generation architecture consists of two major design elements i.e. the cloud service provider and the client. The architecture shifts data, applications and development environments to large data centers thereby providing storage, software and platform services online. The notion on verifying data for intactness is termed as data auditing and the process is...
A quantum string seal encodes the value of a (bit) string as a quantum state in such a way that everyone can extract a non-negligible amount of available information on the string by a suitable measurement. Moreover, such measurement must disturb the quantum state and is likely to be detected by an authorized verifier. In this way, the intactness of the encoded quantum state plays the role of a...
The herpes simplex virus thymidine kinase (TK) gene is transcriptionally activated in trans ("transactivated") by virus-encoded proteins during the infectious cycle. We show that TK plasmids introduced into a HeLa cell transient transcription assay system are also transactivated after infection with a TK- virus. Several aspects of this response are similar to regulation during the normal infect...
The effect of exogenous cytochrome c on respiration rate of the rat and human heart mitochondria was assessed in situ, using permeabilized fibers. It was (i) much more pronounced in State 2 and 4 than in State 3 with all the respiratory substrates (pyruvate+malate, succinate, palmitoyl-CoA+carnitine and octanoyl-L-carnitine), (ii) different with different substrates, (iii) much higher after isc...
The accepted derivation of lignins from non(enzymatically)-controlled radical coupling reactions has been recently challenged, and it is relevant to ascertain unequivocally whether lignins are or are not (as normally assumed) optically active. Two approaches were used. First, DFRC (derivatization followed by reductive cleavage) dimers derived from beta-5- and beta-beta-units in pine lignins, wh...
The question of suffering and its relation to organic illness has rarely been addressed in the medical literature. This article offers a description of the nature and causes of suffering in patients undergoing medical treatment. A distinction based on clinical observations is made between suffering and physical distress. Suffering is experienced by persons, not merely by bodies, and has its sou...
Methods for the cryopreservation of protein import and integration in pea chloroplasts and of protein import or protein synthesis in tobacco mitochondria were modified to yield enzymatically active cryopreserved etioplasts from barley (Hordeum vulgare L.). The cryoprotectants ethylene glycol and dimethy sulfoxide were about 64 and 77% effective, respectively, for the cryopreservation of etiopla...
PURPOSE OF REVIEW Tight junctions (TJs) are specialized differentiations of epithelial and endothelial cell membranes. TJs play an important role in the adhesion of cells and their interaction with each other. Most cancers originate from epithelial cells. Thus, it is of significance to examine the role of TJs in the tumor microenvironment (TME) and how they affect cancer metastasis. RECENT FI...
Two forces are converging, creating conditions both challenging and potentially fruitful for occupational therapy. The profession's knowledge base describing occupation is growing exponentially. At the same time, functional outcomes of intervention are being increasingly valued within the health care environment. Other professions imitate and claim our areas of expertise in the most flattering ...
