When common things aren't so common: A case report of hepatopulmonary syndrome.

A 60-year-old smoker with a history of liver cirrhosis and chronic obstructive pulmonary syndrome (COPD) presented with hypoxic respiratory failure. This was felt secondary to an exacerbation of COPD. Despite treatment, the patient required 10 L of oxygen to achieve saturations of 88% on ambulation.

Design of a thrombin resistant human acidic fibroblast growth factor (hFGF1) variant that exhibits enhanced cell proliferation activity.

Acidic fibroblast growth factors (FGF1s) are heparin binding proteins that regulate a wide array of key cellular processes and are also candidates for promising biomedical applications. FGF1-based therapeutic applications are currently limited due to their inherent thermal instability and susceptibility to proteases. Using a wide range of biophysical and biochemical techniques, we demonstrate that reversal of charge on a well-conserved positively charged amino acid, R136, in the heparin binding pocket drastically increases the resistance to proteases, thermal stability, and cell proliferation activity of the human acidic fibroblast growth factor (hFGF1).

Dyslipidemia and Diabetic Macular Edema: A Systematic Review and Meta-Analysis.

Topic: A systematic review and meta-analysis of dyslipidemia and diabetic macular edema (DME).

Clinical Relevance: Diabetic macular edema causes impairment of vision in patients with diabetes, and dyslipidemia has been reported as a risk factor for its development. A systematic review with a meta-analysis was undertaken to examine the evidence of an association between dyslipidemia and DME.

Health behaviour mediates the relationship between Type D personality and subjective health in the general population.

Type D personality is associated with unhealthy behaviour and poor subjective health in the general population. This study investigated whether health behaviour mediates the relationship between Type D and subjective health. There were 217 participants who completed measures of Type D, health-related behaviour, physical symptoms and quality of life.

Physiological responses to 1000-m ergometer time-trial performance in outrigger canoeing.

Graded exercise tests are commonly used to assess peak physiological capacities of athletes. However, unlike time trials, these tests do not provide performance information. The aim of this study was to examine the peak physiological responses of female outrigger canoeists to a 1000-m ergometer time trial and compare the time-trial performance to two graded exercise tests performed at increments of 7.

Effects of a 12-month exercise program on cardiorespiratory health indicators of Vietnam War veterans resident in the tropics.

Objective: To measure the effect of a combined aerobic and resistance exercise program on key cardiovascular disease risk factors (i.e. body composition or anthropometry and cardiorespiratory function) of Australian male, Vietnam War veterans living in the tropics.

Comparison of physiological responses to graded exercise test performance in outrigger canoeing.

The aim of this study was to establish a graded exercise test protocol for determining the peak physiological responses of female outrigger canoeists. Seventeen trained female outrigger canoeists completed two outrigger ergometer graded exercise test protocols in random order: (1) 25 W power output for 2 min increasing by 7.5 W every minute until exhaustion; and (2) 25 W power output for 2 min increasing by 15 W every 2 min to exhaustion.

Blood lactate, heart rate and rating of perceived exertion responses of elite surf lifesavers to high-performance competition.

A paucity of empirical research exists into surf lifesaving competition from which coaches and athletes may formulate training and recovery strategies. Seventeen (male=9; female=8) high-performance surf lifesavers (21.2+/-3.

Kinematics of the field hockey penalty corner push-in.

The aims of the study were to determine those variables that significantly affect push-in execution and thereby formulate coaching recommendations specific to the push-in. Two 50 Hz video cameras recorded transverse and longitudinal views of push-in trials performed by eight experienced and nine inexperienced male push-in performers. Video footage was digitized for data analysis of ball speed, stance width, drag distance, drag time, drag speed, centre of massy displacement and segment and stick displacements and velocities.
