High efficacy of adefovir and entecavir combination therapy in patients with nucleoside-refractory hepatitis B.

Background/aims: Newly developed and potent antiviral agents suffer from the problem of drug resistance. Multidrug resistance is a major impediment in the treatment of patients with chronic hepatitis B (CHB). In line with American Association for the Study of Liver Diseases guidelines, adefovir dipivoxil (ADV) add-on therapy is recommended in the case of lamivudine resistance, while tenofovir disoproxil fumarate (TDF) is recommended for ADV or entecavir (ETV) resistance.

Non-invasive prenatal detection of achondroplasia using circulating fetal DNA in maternal plasma.

Purpose: To perform a reliable non-invasive detection of the fetal achondroplasia using maternal plasma.

Methods: We developed a quantitative fluorescent-polymerase chain reaction (QF-PCR) method suitable for detection of the FGFR3 mutation (G1138A) causing achondroplasia. This method was applied in a non-invasive detection of the fetal achondroplasia using circulating fetal-DNA (cf-DNA) in maternal plasma.

Anti-inflammatory and anti-allergic effects of kefir in a mouse asthma model.

Kefir is a microbial symbiont mixture that produces jelly-like grains. As a widely used neutraceutical, however, the therapeutic applicability of kefir is not certain. In order to investigate the pharmacological effects of kefir, we used a mouse asthma model, in which airway inflammation and airway remodeling was produced by ovalbumin sensitization and challenge.
