Bioactive sesquiterpene lactones from Elephantopus scaber: semi-synthesis, target fishing, anti-malignant glioma efficacy in vitro and in vivo.

Traditional Chinese Medicine (TCM) offers distinct advantages in the treatment of tumors, since it serves dually as both a medicinal treatment and a dietary therapy. Elephantopus scaber (E. scaber), with a plethora of folk medicinal usage for treating pneumonia and hepatitis, contains sesquiterpene lactone (SL) as the primary component for therapeutic efficacy.

Electronic and thermal transport properties of the metallic antiferromagnet MnSn.

We report the structure, magnetic and electrical/thermal transport properties of the antiferromagnet MnSn. Importantly, the existence of the two antiferromagnetic states below (∼320 K) is confirmed by magnetism and electrical transport measurements. An unsaturated positive magnetoresistance up to 150% at ∼9 was observed at 5 K, whereas the magnetoresistance becomes negative in the whole range at high temperatures ( > 74 K).

Analyzing Operating Room Utilization in a Private Medical Center in Israel.

Background: Surgery is a core activity in hospitals. Operating rooms have some of the most important and vital functions in medical centers. The operating rooms and their staff are a valuable infrastructure resource and their availability and preparedness affect human life and quality of care.

Observation of the Spin-Glass Behavior in Co-Based Antiperovskite Nitride GeNCo3.

Single-phase antiperovskite nitride GeNCo3 with space group Pm3̅m is successfully synthesized by a solid-gas reaction. The crystal structure, magnetism, specific heat at low temperatures, Hall effect, and electrical and thermal transport properties are widely investigated. Exhilaratingly, a canonical spin-glass (SG) behavior is observed in GeNCo3 with a freezing temperature T0 = 79.

Detection of histidine kinases via a filter-based assay and reverse-phase thin-layer chromatographic phosphoamino acid analysis.

The methods that detect histidine phosphorylation have largely been either laborious or difficult to apply quantitatively. The major difficulty in assessing for its presence is its alkali-stable, acid-labile nature. While an assay that detects alkali-stable phosphorylation has been developed, it does not distinguish phosphohistidine from other alkali-stable phosphoamino acids.

Clinical significance of TT virus (TTV) infection in chronic hepatitis C patients with high dose interferon-alpha therapy in Taiwan: re-evaluated by using new set of TTV primers.

BACKGROUND: The clinical significance of TT virus (TTV) coinfection in chronic hepatitis C (CHC) patients and influence of TTV viremia on hepatitis C virus (HCV) response to high dose interferon-alpha therapy in Taiwan were investigated. MATERIALS AND METHODS: Total 102 HCV RNA-positive CHC patients were enrolled. TTV DNA (using polymerase chain reaction primers derived from 5' non-coding region and open reading frame 2), alanine aminotransferase (ALT), GB virus-C/hepatitis G virus (GBV-C/HGV) RNA, anti-E2 antibody, genotype and RNA levels of HCV were tested.
