Hepatic stimulator substance (HSS) has been shown to protect liver cells from various toxins. However, the mechanism by which HSS protects hepatocytes remains unclear. In this study, we established BEL-7402 cells that stably express HSS and analyzed the protective ability of HSS on cells through mitochondrial permeability (MP). After administration of carbonyl cyanide m-chlorophenylhydrazone (C...

Recently, hierarchically semiseparable (HSS) matrices have been used in the development of fast direct sparse solvers. Key applications of HSS algorithms, coupled with multifrontal solvers, appear in solving certain large-scale computational inverse problems. Here, we develop massively parallel HSS algorithms appearing in these solution methods, namely, parallel HSS construction using the rank ...

Semiseparable matrices and many other rank-structured matrices have been widely used in developing new fast matrix algorithms. In this paper, we generalize the hierarchically semiseparable (HSS) matrix representations and propose some fast algorithms for HSS matrices. We represent HSS matrices in terms of general binary HSS trees and use simplified postordering notation for HSS forms. Fast HSS ...

High-speed steel (HSS) tools are the most commonly used tools in small and medium-scale industry. Cryogenic treatment can be used to enhance the tool life. Studies on cryogenically treated (CT) cutting tools show micro structural changes in the material that can influence the life of the tools significantly. This paper primarily reports performance of CT HSS tools as compared to untreated (UT) ...

Humanities and Social Sciences (HSS) increasingly absorb knowledge from Hard Sciences, i.e., Science, Technology, Agriculture and Medicine (STAM), as testified by a growing number of citations. However, whether citing more Hard Sciences brings more citations to HSS remains to be investigated. Based on China's HSS articles indexed by the Web of Science during 1998-2014, this paper estimated two-...

In this paper, we study an important class of structured matrices: ”Hierarchically Semi-Separable (HSS)” matrices, for which an efficient hierarchical state based representation called Hierarchically Semi-Separable (HSS) representation can be used to utilize the data sparsity of the HSS matrices. A novel algorithm with O(n) complexity is proposed to construct suboptimal HSS representations from...

Hepatic stimulator substance (HSS) protects liver cells from various toxins. However, the mechanism by which HSS protects hepatocytes remains unclear. In this study, we report that the HSS gene, after transfection into BEL-7402 hepatocma cells, is stably expressed in the mitochondria. Hydrogen peroxide (H(2)O(2))-induced cell apoptosis in the HSS-transfected cells is reduced, as shown by morpho...

BACKGROUND The mechanism of cadmium-induced liver regeneration arrest in relation to hepatic stimulator substance (HSS) biological activity was investigated. MATERIALS AND METHODS In Wistar rats subjected to 65 - 70% partial hepatectomy, saline, cadmium, cadmium and HSS were administered. The rats were also subjected to 30 - 34% partial hepatectomy. Mitotic index, immunochemistry for PCNA, 3[...

Cell motility depends on the rapid growth of cortical actin filaments whose barbed ends are capped in the resting cell. High speed supernates (HSS) of dilute neutrophil lysates contain actin monomers and/or oligomers that can be induced to polymerize by certain stimuli. We questioned whether some of the actin remaining in the supernate after high speed centrifugation exists as occult nucleation...
