Idiopathic pulmonary fibrosis is known as a life-threatening disease with high mortality and limited therapeutic strategies. In addition, the molecular mechanism by which pulmonary fibrosis developed is not fully understood. Asiatic acid (AA) is a triterpenoid, isolated from Centella asiatica, exhibiting efficient anti-inflammatory and anti-oxidative activities. In our study, we attempted to explore the effect of Asiatic acid on bleomycin (BLM)-induced pulmonary fibrosis in mice. The findings indicated that pre-treatment with Asiatic acid inhibited BLM-induced lung injury and fibrosis progression in mice...

Neuropathic pain remains poorly treated for large numbers of patients and little progress has been made in developing novel classes of analgesics. To redress this issue, ziconotide (Prialt(TM) ) was developed and approved as a first in class synthetic version of ω-conotoxin MVIIA, a Cav 2.2 peptide blocker. Unfortunately, the impracticalities of intrathecal delivery, low therapeutic index and severe neurological side effects associated with ziconotide has restricted its use to exceptional circumstances. Ziconotide exhibits no state or use dependent block of Cav 2...

OBJECTIVE: To characterize the concurrent activation of rectus femoris (RF) and medial gastrocnemius (MG) muscles (extensor coactivation) during gait in subjects with pronounced resting hypertonia after acquired brain injury (ABI) and examine changes after intrathecal baclofen (ITB) bolus injection. METHODS: Magnitude and duration of extensor coactivation during different phases of gait were assessed by recording gait kinematics and activity in bilateral RF and MG muscles in 18 controls and 18 ABI subjects before and at 2, 4, and 6h after a 50-μg ITB injection...

Group schema therapy (GST) has been proposed as a novel long-term treatment programme for borderline and cluster C personality disorders. We implemented a short-term GST programme (12-15 sessions, based on the manual by Farrell and Shaw (2012), including both cognitive / behavioural and experiential interventions for in-patients (n=9) with either borderline or cluster C personality disorders (and axis I co-morbidities) treated in a (sub)acute psychiatric in-patient setting. We evaluated pre- and post-treatment self-report of maladaptive and adaptive schema modes (using the SMI) and early maladaptive schemas (YSQ-3), as well as overall symptom severity (brief symptom check list, BSCL-53-S), patient satisfaction (ZUF-8) and group climate and coherence (GCQ-S)...

The aim of this work was to study the thermal properties and interactions during co-combustion of rape straw (RS) before and after water-washing with bituminous coal. A series of experiments was conducted to investigate the properties and interactions during co-combustion of RS with bituminous coal (at 10, 20, 40 and 60% RS). The feasibility and potential of water-washing as an RS pre-treatment was also explored. Reactivity and the amount of heat released followed a quadratic trend, while changes to the degree of interactions between the fuels conformed to a cosine curve...

Kappaphycus alvarezii seaweed belongs to the class of red alga (Rhodophyta). The granules obtained after recovery of "sap" (liquid plant stimulant) from freshly harvested alga is a promising biomass feedstock for energy application. Herein we report the kinetic behaviour of the granules using thermogravimetric analysis (TGA) at different heating rates in N2 atmosphere and thermogravimetric-mass spectrometry (TG-MS) analysis. Sawdust as lignocellulosic biomass is considered for comparative study. Four different kinetic models (i) multilinear regression technique, (ii) Friedman method, (iii) Flynn-Wall-Ozawa (FWO) method and (iv) Kissinger-Akahira-Sunose (KAS) method are used to evaluate the apparent activation energy (Ea), the pre-exponential factor (Aα) and the overall reaction order (n)...

REVIEW
Timothy Nj Bullock
The capacity of the immune system to recognize and respond to tumors has been appreciated for over 100 years. However, clinical success has largely depended on the elucidation of the positive and negative regulators of effector cells after their activation via the antigen cell receptor. On the one hand, effector cells upregulate checkpoint molecules that are thought to play a role in limiting immunopathology. On the other, second and third waves of costimulation are often required to promote the expansion, survival and differentiation of effector cells...

Acute aerobic exercise improves mood and activates the endocannabinoid (eCB) system in physically active individuals; however, both mood and eCB responses to exercise may vary based on habitual levels of physical activity. PURPOSE: To examine eCB and mood responses to prescribed and preferred exercise among individuals with low, moderate, and high levels of physical activity. METHODS: Thirty-six healthy adults (21±4yrs) were recruited from low (≤60min moderate-vigorous physical activity [MVPA]/wk), moderate (150-299min MVPA/wk), and high (≥300 MVPA/wk) physical activity groups...

OBJECTIVES: The high percentage of failed clinical trials for anti-depressant medications, especially in elderly populations, obscures the fact that some patients may benefit greatly from treatment. Early detection of patients who may benefit most from antidepressant medication may improve treatment decisions. We examined whether depressed patients in a large clinical trial exhibit distinct trajectories of early symptom change that predict differential response to medication or placebo...

Competitive sports activity is associated with an increased risk of sudden cardiovascular death (SCD) in adolescents and young adults with clinically silent cardiovascular disorders. While in middle-aged/senior athletes atherosclerotic coronary artery disease accounts for the vast majority of SCDs, in young athletes the spectrum of substrates is wider and includes inherited (cardiomyopathies) and congenital (anomalous origin of coronary arteries) structural heart diseases. Inherited ion channel diseases have been implicated in SCDs occurring with an apparently normal heart at autopsy...

The relative importance of sarcopenia and its individual components as independent predictors of mortality in the dialysis population has not been determined. We estimated whole-body muscle mass using pre-dialysis bioimpedance spectroscopy measurements in 645 ACTIVE/ADIPOSE-enrolled prevalent hemodialysis patients from San Francisco and Atlanta. Low muscle mass was defined as two standard deviations below sex-specific means for young adults from NHANES and indexed to height(2), body weight, body surface area, or body mass index...

Turning genes on and off is essential for development and homeostasis, yet little is known about the sequence and causal role of chromatin state changes during the repression of active genes. This is surprising, as defective gene silencing underlies developmental abnormalities and disease. Here we delineate the sequence and functional contribution of transcriptional repression mechanisms at high temporal resolution. Inducible entry of the NuRD-interacting transcriptional regulator Ikaros into mouse pre-B cell nuclei triggered immediate binding to target gene promoters...

OBJECTIVE: A new active safety concept that engages the driver's psychosensory pain-processing mechanism to automatically trigger vigilance enhancement on-demand was proposed in Chang ( 2012 ). This concept is based on the hypothesis that a human's pain threshold will decline as he/she becomes drowsy, consequently triggering the vigilance enhancer. The objective of this pilot study was to develop methods to test this hypothesis, the results of which could lead to further refinement of the hypothesis and methods, with the ultimate goal of developing new active safety concepts that exploit the driver's endogenous psychosensory pain-processing mechanisms...
