MicroRNAs derived from the insect virus HzNV-1 promote lytic infection by suppressing histone methylation.

Heliothis zea nudivirus-1 (HzNV-1) is an insect virus that can induce both lytic and latent infections in various insect cell lines. During latent infection, several microRNAs (miRNAs) are produced from persistency-associated gene 1 (pag1) as the only detectable HzNV-1 transcript. Previous studies have shown that the pag1 gene suppresses the immediate-early gene hhi1 and promotes host switching into a latent infection via miRNAs derived from pag1.

Resolution of transmission electron backscatter diffraction in aluminum and silver: Effect of the atomic number.

This work aims to investigate the influence of intrinsic and extrinsic factors on the physical resolution of the transmission electron backscattered diffraction technique (t-EBSD) in aluminum and silver. Here, we focus on the intrinsic factors, namely, atomic number and thickness of the specimen, and extrinsic set-up factors, which include the electron beam voltage, working distance, and specimen tilt. The working distance and tilt angle, which are selected as 12 mm and 60° for Al and 12 mm and 50° for Ag, respectively, reveal a sharp pattern with high contrast.

Robotic totally endoscopic coronary artery bypass for isolated ostial stenosis of the left coronary artery.

Isolated ostial stenosis (IOS) is a rare disease that encroaches on aorto-coronary junction of uncertain etiology. All distal coronary vessels present normally. IOS occurs predominantly in premenopausal young women with few risk factors for atherosclerotic disease.

Endotoxemia is associated with acute coronary syndrome in patients with end stage kidney disease.

Most ESRD patients have systemic inflammation, and increasing the risk of cardiovascular event. Endotoxin derived from lipopolysaccharide of Gram negative bacteria accounts for 70% of intestinal bacteria, leading to release of proinflammatory cytokines and negative cardiovascular effect.

Dermoscopic features of livedoid vasculopathy.

Livedoid vasculopathy (atrophie blanche) is a form of thrombotic vasculopathy. It is characterized by small ulcers that become crusted, and heal after several months to produce white atrophic scars. The most commonly affected sites are the lower legs, in particular the dorsum of the feet and ankles.

Effects of accelerating voltage and specimen thickness on the spatial resolution of transmission electron backscatter diffraction in Cu.

A quantitative approach was proposed to determine the spatial resolution of transmission electron backscatter diffraction (t-EBSD) and to understand the limits of spatial resolution of t-EBSD. In this approach, Cu bicrystals and digital image correlation were employed. The effects of accelerating voltage and specimen thickness on the spatial resolution of t-EBSD were also investigated.

Upregulation of cyclin-dependent kinase inhibitors CDKN1B and CDKN1C in hepatocellular carcinoma-derived cells via goniothalamin-mediated protein stabilization and epigenetic modifications.

Cell cycle deregulation is common in human hepatocellular carcinoma (HCC). To ensure proper cell cycle controlling, cyclin/cyclin-dependent kinases (CDK) complexes are tightly regulated by CDK inhibitors (CKIs) in normal cells. However, insufficient cyclin-dependent kinase inhibitor 1B (CDKN1B, also known as p27) and CDKN1C (p57) proteins are characteristics of high-risk HCC.

Lipopolysaccharide- and glutamate-induced hypothalamic hydroxyl radical elevation and fever can be suppressed by N-methyl-D-aspartate-receptor antagonists.

The purpose of the current study was to explore the effects of N-methyl-D-aspartate (NMDA)-receptor antagonists (MK-801 and LY235959) administered intracerebroventricularly on the changes of both core temperature and hypothalamic levels of 2,3-dihydroxybenzoic acid (2,3-DHBA) induced by intracerebroventricular injection of glutamate (100 - 400 microg at 10 microl/rabbit) or intravenous administration of lipopolysaccharide (LPS) (2 microg/kg) in rabbits. The measurements of 2,3-DHBA were used as an index of the intrahypothalamic levels of hydroxyl radicals. The rise in both the core temperature and hypothalamic 2,3-DHBA could be induced by intracerebroventricular injection of glutamate or intravenous administration of LPS.
