Heart rate variability and fractal dimension during orthostatic challenges.

• Gary C. Butler, Yoshitaka Yamamoto, Hua Cheng Xing, David R. Northey, Richard L. Hughson
• Journal of applied physiology
• 1993

Heart rate variability (HRV) spectral analysis has been used as a tool for short-term assessment of parasympathetic (PNS) and sympathetic nervous system (SNS) control of heart rate. However, it has… (More)

Kinetics of ventilation and gas exchange during supine and upright cycle exercise

• Richard L. Hughson, Hua Cheng Xing, Cornelia M. Borkhoff, Gary C. Butler
• European Journal of Applied Physiology and…
• 1991

The dynamics of ventilation (VE), oxygen uptake (VO2), carbon dioxide output (VCO2), and heart rate (f c) were studied in 12 healthy young men during upright and supine exercise. Responses to maximal… (More)

Arachidonic acid offsets the effects on mouse brain and behavior of a diet with a low (n-6):(n-3) ratio and very high levels of docosahexaenoic acid.

• Patricia E. Wainwright, Hua Cheng Xing, L. M Mutsaers, Dawn McCutcheon, David Kyle
• The Journal of nutrition
• 1997

This study investigated the effects of varying dietary levels of very long-chain polyunsaturated fatty acids on growth, brain fatty acid composition and behavior in mice. Five groups of pregnant and… (More)

Adrenocortical response to stress in fasted and unfasted artificially reared 12-day-old rat pups.

• Glenn R. Ward, Hua Cheng Xing, Nancy Carnide, Jane Slivchak, Patricia E. Wainwright
• Developmental psychobiology
• 2004

Recent studies have compared artificially reared (AR) rats with dam-reared rats on behavioral outcomes but, despite the fact that they are deprived of their mothers during the stress hyporesponsive… (More)

Water maze performance is unaffected in artificially reared rats fed diets supplemented with arachidonic acid and docosahexaenoic acid.

• Patricia E. Wainwright, Hua Cheng Xing, +4 authors Massimo Montalto
• The Journal of nutrition
• 1999

Four groups of male Long-Evans rats were reared artificially from postnatal d 5 to 18 by being fed through a gastrostomy tube with rat milk substitutes containing oils providing 10% linoleic acid and… (More)

Alignment of ventilation and gas fraction for breath-by-breath respiratory gas exchange calculations in exercise.

• Richard L. Hughson, David R. Northey, Hua Cheng Xing, Bruce H. Dietrich, J E Cochrane
• Computers and biomedical research, an…
• 1991

The effects of correct alignment of the ventilation and fractional gas concentration during breath-by-breath calculation of oxygen uptake (VO2) have been examined during exercise in four subjects, at… (More)

Cardiovascular response to 4 hours of 6 degrees head-down tilt or of 30 degrees head-up tilt bed rest.

• Gary C. Butler, Hua Cheng Xing, Richard L. Hughson
• Aviation, space, and environmental medicine
• 1990

The cardiovascular responses to 4 h of 6 degrees head-down tilt (HDT) were compared to those of 4 h of 30 degrees head-up tilt (HUT) following a period of 1 h baseline in the 30 degrees HUT position.… (More)

Time domain analysis of oxygen uptake during pseudorandom binary sequence exercise tests.

• Richard L. Hughson, L A Cuervo, +4 authors George D. Swanson
• Journal of applied physiology
• 1991

Pseudorandom binary sequence (PRBS) exercise tests involve repeated switching between two work rates (WR) according to a computer-generated pattern. This paper presents an approach to analysis of O2… (More)

Probing heart rate and blood pressure control mechanisms during graded levels of lower body negative pressure (LBNP).

• Gary C. Butler, Yoshitaka Yamamoto, Hua Cheng Xing, David R. Northey, Richard L. Hughson
• Microgravity quarterly : MGQ
• 1992

Following space flight or head down tilt bed rest, cardiovascular deconditioning is often observed as a failure to maintain arterial blood pressure with symptoms of presyncope or syncope. LBNP can be… (More)

Dietary trans fatty acids combined with a marginal essential fatty acid status during the pre- and postnatal periods do not affect growth or brain fatty acids but may alter behavioral development in…

• Ine P. M. Wauben, Hua Cheng Xing, Dawn McCutcheon, Patricia E. Wainwright
• The Journal of nutrition
• 2001

The objective of this study was to investigate whether dietary trans fatty acids (TFA) during the pre- and postnatal periods would exacerbate the effects of marginal essential fatty acid (EFA) status… (More)
