Effect of theophylline on the warm-up phenomenon.

Published: November 1999

This study examined whether the adenosine receptor antagonist theophylline prevents the warm-up phenomenon in patients with stable angina undergoing serial exercise tests. Our findings offer evidence that adenosine does not play a role in the warm-up phenomenon, and indirectly suggest that the warm-up phenomenon does not represent ischemic preconditioning in humans.

Background: Health misinformation is abundant online and becoming an increasingly pressing concern for both oncology practitioners and patients with cancer. On social media platforms, including the popular audiovisual app TikTok, the flourishing alternative health industry is further contributing to the spread of misleading and often harmful information, endangering patients' health and outcomes and sowing distrust of the medical community. The prevalence of false and potentially dangerous treatments on a platform that is used as a quasi-search engine by young people poses a serious risk to the health of patients with cancer.

The high concentration of oxygenated haemoglobin (OHb) in the prefrontal cortex (PFC) during exercise improves cognitive performance. In this study, we aimed to elucidate the relationship of cognitive function with the OHb concentration difference between the left and right PFC (L-PFC and R-PFC, respectively) during sustained exercise. We enrolled 12 healthy adult males who, after a 4-min rest and warm-up, performed a 40-min exercise regime at a workload corresponding to 50% maximal oxygen consumption.

Article Synopsis
  • Systemic sclerosis (SSc) is a rare disease that can affect different parts of the body, and this case is about a 51-year-old woman who had swelling in her eyelid.
  • Doctors found she had an enlarged lacrimal gland and inflammatory symptoms that didn’t get better with regular treatments, which led them to explore further possible conditions.
  • This case is important because it shows that SSc, specifically CREST syndrome, can have unusual symptoms like swelling in the eyes, and doctors need to think about different diagnoses when they see such signs.

Acute partial sleep deprivation attenuates blood pressure responses to cycling exercise.

Am J Physiol Heart Circ Physiol

October 2024

Human Cardiovascular Physiology Laboratory, Department of Human Health and Nutritional Sciences, University of Guelph, Guelph, Ontario, Canada.

Exaggerated blood pressure (BP) responses during exercise are independently associated with future development of hypertension. Partial sleep deprivation (PSD) can increase 24-h ambulatory BP, but the effects on exercise BP are unclear. We hypothesized that acute PSD would augment the BP response to constant load cycling exercise and a 20-min time trial.

Localized Evaporative Cooling Explains Observed Ocular Surface-Temperature Patterns.

Invest Ophthalmol Vis Sci

August 2024

Herbert Wertheim School of Optometry & Vision Science, University of California - Berkeley, Berkeley California, United States.

Purpose: We determined interblink corneal surface-temperature decline and tear-film evaporation rates of localized tear breakup cold regions (LCRs) and localized tear unbroken warm regions (LWRs) of the corneal surface, as well as that of the overall average corneal surface.

Methods: Each subject underwent 4 inter-day visits where the interblink corneal surface-temperature history of the right eye was measured using a FLIR A655sc infrared thermographer. Corneal surface temperature history was analyzed to determine the overall, LCR, and LWR temperature-decline rates.
