Exploring the Possible Relationship Between Mother's Dietary Intake of Tryptophan and Melatonin Levels in Her Breast Milk.

Tryptophan is an essential amino acid that is not produced in the body and can only be consumed through diet. Tryptophan is a precursor for serotonin, which, in turn, helps produce melatonin. Melatonin exhibits a circadian rhythm, peaking at night and dissipating during the day, with basal levels significantly differing between mothers.

Ultrasound Screening of Achilles Tendon, Patellar Tendon, and Plantar Fascia for Pain Development in Collegiate Athletes: A Multi-institutional Prospective Evaluation.

Background: Diagnostic ultrasound can evaluate musculoskeletal structures for abnormalities that correlate with tendinopathy and fasciopathy. Previous literature suggests that sonographic screening of tendons and fascia can identify structures that are at risk for developing pain, although this has not been evaluated in collegiate athletes competing in a variety of sports.

Purpose: To evaluate the use of ultrasound for screening the patellar tendon, Achilles tendon, and plantar fascia for time-loss injury in collegiate athletes during a full year.
