Which came first, overall bigger brains or larger brain regions that control specialized behaviors? Neuroscientists have debated this question for decades, but a new Cornell study settles the score.Th...
Changes in skeletal muscle and organ size after a weight-loss intervention in overweight and obese type 2 diabetic patients
type 2 diabetes magnetic resonance imaging body composition skeletal muscle organ mass weight loss Look AHEAD trial
2018/11/12
Background: The effect of a weight-loss intervention on the masses of lean tissues and organs in humans is not well known.Objective: We studied the effects of a diet and exercise weight-loss intervent...
Immune function in rural Gambian children is not related to season of birth, birth size, or maternal supplementation status
maternal supplementation pregnancy children
2016/6/14
We previously showed that mortality from infectious
diseases among young adults in rural Gambia is strongly
correlated with the season of their birth. This suggests that early
life insults that inv...
Portion-size estimation training in second- and third-grade American Indian children
Portion-size estimation diet assessment dietary intake
2016/5/31
Training in portion-size estimation is known to
improve the accuracy of dietary self-reporting in adults, but
there is no comparable evidence for children. To obtain this
information, we studied 11...
Energy intake, not energy output, is a determinant of body size in infants
Obesity body size infants
2016/5/30
It has been proposed that the primary determinants
of body weight at 1 y of age are genetic background, as represented
by parental obesity, and low total energy expenditure.
Comparison of Radiological Findings of Chest X-Ray With Echocardiography in Determination of the Heart Size
Echocardiography Thoracic Radiography Enlarged Heart Cardiomegaly
2015/10/16
Background: Heart size is an important and effective parameter in chest X-ray (CXR) interpretation. Studies indicate that, especially in middle-aged men, increased cardiothoracic ratio (CTR) is associ...
Short-Term Free-Fall Landing Causes Reduced Bone Size and Bending Energy in Femora of Growing Rats
Bone mechanical load biomechanical properties post-yield energy animal model
2015/5/14
The purpose of this study was to determine the effects of a mechanical loading course (short-term free-fall landing) on femoral geometry and biomechanical properties in growing rats. Thirty-two female...
Effects of Electrostimulation with Blood Flow Restriction on Muscle Size and Strength
MUSCLE ADAPTATIONS TRAINING ELECTRICALLY EVOKED FORCE OCCLUSION KNEE EXTENSORS
2017/4/20
Purpose: Low-load voluntary exercise can induce muscle hypertrophy and strength gain in working muscles when combined with blood flow restriction (BFR). However, it is unknown whether such hypertrophy...

Can Deterministic Mechanical Size Effects Contribute to Fracture and Microdamage Accumulation in Trabecular Bone?
microdamage biomechanics fracture
2014/12/4
Failure of bone under monotonic and cyclic loading is related to the bone mineral density, the quality of the bone matrix, and the evolution of microcracks. The theory of linear elastic fracture mecha...
