Different Surface Electromyography of Propagated Sensation along Meridians Produced by Acupuncturing Quchi Acupoint (LI11) or Control Points.

This study investigated the propagated sensation along meridians (PSM) produced respectively by acupuncture at a specific acupoint of right-side Quchi (LI11), a nonacupoint on meridian (control meridian point), and neither meridian nor acupoint (control point). All the stimulated points were on the right brachioradialis along the large intestine meridian of hand Yangming. Surface electromyography (sEMG) was used to reflect the activity of the brachioradialis along the large intestine meridian of hand Yangming.

[Application of associated symptom and sign-based acupoint selection in acupuncture-moxibustion treatment].

Based on traditional acupuncture-moxibustion treatment ideas, with differentiation of channels and collaterals as main part and feature, the important role of associated symptom and sign-based acupoint selection in acupuncture-moxibustion treatment is explained from angles of philosophy and medicine. Combined with clinical experience of acupuncture and moxibustion, the category of associated symptom and sign-based acupoint selection is explained in detail to make sure the accuracy of acupuncture-moxibustion differentiation. It could show uniqueness and advantage of theory and clinic in acupuncture-moxibustion and provide theoretical references in making acupuncture-moxibustion prescription to improve effectiveness of clinical treatment.

The impacts of along-channel acupuncture on the protein expressions of the chloride channel of the rats with myocardial ischemia.

Recent evidence suggests that chloride (CL(-)) channels are involved in myocardial ischemia. In this study, the impact of acupuncture on the protein expressions of Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) and CLC-2 CL(-) channel of the rats with myocardial ischemia were tested and its mechanism was explored. The rats for experiment were distributed randomly into 5 groups: blank control group, modeling control group, Neiguan (PC-6) treatment group, Lieque (LU-7) control group, and Non-acupoint control group.

Ghrelin modulates insulin sensitivity and tau phosphorylation in high glucose-induced hippocampal neurons.

Ghrelin, a 28-amino acid brain-gut peptide expressed in periphery tissues and the central nervous system, has been demonstrated to increase insulin sensitivity in adipocytes. Recent data have indicated that insulin resistance exists in the brain and is related to Alzheimer's Disease (AD). The aim of this study was to investigate whether ghrelin increased high glucose-induced hippocampal neuron insulin sensitivity, and further modulated tau phosphorylation.

Alpha-helix 1 in the DNA-binding domain of heat shock factor 1 regulates its heat-induced trimerization and DNA-binding.

Heat shock factor 1 (HSF1) primarily regulates various cellular stress responses. The role of alpha-helix1 (H1) in its DNA-binding domain (DBD) during HSF1 activation remains unknown. Here, HSF1 lacking H1 loses its heat-induced activity, suggesting the importance of the latter.

Two distinct disulfide bonds formed in human heat shock transcription factor 1 act in opposition to regulate its DNA binding activity.

Under circumstances of heat stress, heat shock transcription factor 1 (HSF1) plays important roles in heat shock protein expression. In this study, an increasing concentration of dithiothreitol (DTT) was found to either enhance or inhibit the heat-induced trimerization of HSF1, suggesting the involvement of dual redox-dependent HSF1 activation mechanisms. Our in vitro experiments show that the heat-induced bonding between the cysteine C36 and C103 residues of HSF1 forms an intermolecular disulfide covalent bond (SS-I bond) and that it directly causes HSF1 to trimerize and bond to DNA.

Environmental estrogenic effects and gonadal development in wild goldfish (Carassius auratus).

Serum vitellogenin (VTG) contents of wild goldfish (Carassius auratus) were investigated as a sensitive biomarker for artificial estrogenic compounds in aquatic environments. Goldfish was sampled from a pristine area, a river situated 5 km downstream from a sewage treatment works (STW), and also from the Young-San River in Korea. The female yolk precursor protein VTG was not detected when gonadosomatic index (GSI) was less than 0.
