This study develops and analyzes preconditioned Krylov subspace methods to solve linear systems arising from discretization of the time-independent space-fractional models. First, we apply shifted Grunwald formulas to obtain a stable finite difference approximation to fractional advection-diffusion equations. Then, we employee two preconditioned iterative methods, namely, the preconditioned gen...

Rapidly progressive glomerulonephritis (RPGN) is a syndrome signified by a precipitous loss of renal function, with features of glomerulonephritis including dysmorphic erythrocyturia and glomerular proteinuria. RPGN is associated with extensive crescent formation, and, thus, the clinical term RPGN is often used interchangeably with the pathologic term crescentic glomerulonephritis (CGN). From a...

Marine macroalgae are rich in bioactive compounds that can, when consumed, impart beneficial effects on animal and human health. The red seaweed Chondrus crispus has been reported to have a wide range of health-promoting activities, such as antitumor and antiviral activities. Using a Caenorhabditis elegans infection model, we show that C. crispus water extract (CCWE) enhances host immunity and ...

BACKGROUND & AIMS AIM2 plays an important role in innate immunity, but its role in regulating the immune response to hepatitis B virus (HBV) is unknown. We hypothesized that AIM2 expression is positively correlated with HBV-mediated inflammation in patients with HBV-associated glomerulonephritis (HBV-GN), potentiating inflammation and leading to renal damage. We therefore analyzed the expressio...

The elderly population has significantly increased in China. However, data regarding renal histopathology in this population is lacking. The present study retrospectively analyzed renal disease spectrum of 430 elderly patients who had received renal biopsy at Peking University First Hospital between January 2003 and December 2012. Among 6049 patients receiving renal biopsies during the same per...

5-lipoxygenase (5LOX) is the key enzyme in the synthesis of leukotrienes from arachidonic acid. Hyperglucocorticoidemia, dexamethasone, and aging up-regulate 5LOX in the brain, including the cerebellum in vivo. We studied the mechanisms of dexamethasone-triggered 5LOX upregulation in primary cultures of rat cerebellar granule neurons (CGN). We measured 5LOX mRNA and protein contents, and the fo...

In the development of annotations for a spoken database, an important issue is whether the annotations can be generated automatically with sufficient precision, or whether expensive manual annotations are needed. In this paper, the case of prosodic annotations is discussed, which was investigated on the CGN database (Spoken Dutch Corpus). The main conclusions of this work are as follows. First,...

On the basis of comparative mapping between cattle/sheep and human for milk trait quantitative trait loci (QTL) on BTA3/OAR1, annexin A9 (ANXA9) and solute carrier family 27 (fatty acid transporter), member 3 (SLC27A3) were selected as candidate genes for fat content (FC) in sheep milk. Two other genes in the same region, cingulin (CGN) and acid phosphatase 6, lysophosphatidic (ACP6), were also...

Spatial abilities are generally hypothesized to differ between men and women, and people with different sexual orientations. According to the cross-sex shift hypothesis, gay men are hypothesized to perform in the direction of heterosexual women and lesbian women in the direction of heterosexual men on cognitive tests. This study investigated sexual orientation differences in spatial navigation ...

Memories of sex-atypical behavior and interests in childhood usually differ between homosexual and heterosexual people. However, variation within these broad groups has not previously been explored in detail, especially among women. We utilized data from a postal survey of a nationwide sample of Australian adult twins (n = 4,901, age range: 19-52 years). Among men, 15.2% reported homosexual beh...
