Profile of paritaprevir/ritonavir/ombitasvir plus dasabuvir in the treatment of chronic hepatitis C virus genotype 1 infection.

Over the last several years, many advances have been made in the treatment of chronic hepatitis C virus (HCV) infection with the development of direct-acting antivirals. Paritaprevir/ritonavir/ombitasvir with dasabuvir (PrOD) is a novel combination of a nonstructural (NS) 3/4A protein inhibitor boosted by ritonavir, an NS5A protein inhibitor, and an NS5B nonnucleoside polymerase inhibitor. This review aims to discuss the pharmacology, efficacy, safety, drug interactions, and viral drug resistance of PrOD in the treatment of HCV genotype 1 infections.

Use of emergency departments by known epileptic patients: An underestimated problem?

Background And Purpose: Seizure is a frequent reason of admission in emergency department (ED) but little is known about the proportion and the characteristics of known epileptic patients (KEPs) who used emergency services.

Methods: Over a 12-month period, we prospectively recruited adults admitted for seizure to a tertiary hospital ED. For KEPs, clinical epilepsy features and characteristics of the admission were collected.

PI3K-δ and PI3K-γ inhibition by IPI-145 abrogates immune responses and suppresses activity in autoimmune and inflammatory disease models.

Phosphoinositide-3 kinase (PI3K)-δ and PI3K-γ are preferentially expressed in immune cells, and inhibitors targeting these isoforms are hypothesized to have anti-inflammatory activity by affecting the adaptive and innate immune response. We report on a potent oral PI3K-δ and PI3K-γ inhibitor (IPI-145) and characterize this compound in biochemical, cellular, and in vivo assays. These studies demonstrate that IPI-145 exerts profound effects on adaptive and innate immunity by inhibiting B and T cell proliferation, blocking neutrophil migration, and inhibiting basophil activation.

Biochemical and psychometric evaluation of Self-Healing Qigong as a stress reduction tool among first year nursing and midwifery students.

Background: Qigong, a traditional Chinese exercise, has a potential role in the management of stress.

Objective: To examine the influence of Qigong training on depression, anxiety and stress.

Design: A randomised control trial among first year student participants.

Heat shock protein 90 is a promising target for effective growth inhibition of gastrointestinal neuroendocrine tumors.

Treatment of gastroenteropancreatic neuroendocrine tumors (GEP-NET) is still unsatisfactory and innovative therapeutic approaches are urgently needed. Heat shock protein 90 (Hsp90) is overexpressed in a wide range of tumor types and is an emerging target for the treatment of cancer. However, the potential activity of Hsp90 inhibitors in GEP-NET has not yet been investigated.

Antitumor activity of the Hsp90 inhibitor IPI-504 in HER2-positive trastuzumab-resistant breast cancer.

Hsp90 facilitates the maturation and stability of numerous oncoproteins, including HER2. The aim of this study was to assess the antitumor activity of the Hsp90 inhibitor IPI-504 in trastuzumab-resistant, HER2-overexpressing breast cancer cells. Therapy with trastuzumab, IPI-504, and the combination of trastuzumab and IPI-504 was evaluated in trastuzumab-sensitive and trastuzumab-resistant cells.

The antiproliferative activity of the heat shock protein 90 inhibitor IPI-504 is not dependent on NAD(P)H:quinone oxidoreductase 1 activity in vivo.

IPI-504, a water-soluble ansamycin analogue currently being investigated in clinical trials, is a potent inhibitor of the protein chaperone heat shock protein 90 (Hsp90). Inhibition of Hsp90 by IPI-504 triggers the degradation of important oncogenic client proteins. In cells, the free base of IPI-504 hydroquinone exists in a dynamic redox equilibrium with its corresponding quinone (17-AAG); the hydroquinone form binding 50 times more tightly to Hsp90.

Circadian clockwork genes are expressed in the reproductive tract and conceptus of the early pregnant mouse.

Circadian genes are expressed in some peripheral tissues, but the expression status of the female reproductive tract and the conceptus over the preimplantation period is unknown. Oocytes, uterine, oviducal tissues and preimplantation conceptuses from days 1-4 of mouse pregnancy were analysed for transcript presence by reverse transcription polymerase chain reaction. Transcripts encoded by the seven known mammalian canonical circadian genes (Per1-3, Cry1-2, Bmal1 and Clock), plus the mammalian genetic homologue of the Drosophila canonical gene Timeless, were detected in the uteri and oviducts taken from mice on days 1-4 of pregnancy and in unfertilized oocytes.
