A new mouse model of neurofibromatosis 1 closely replicates the human condition, allowing for more extensive and accurate preclinical testing of potential therapies. The model has been used to test chemotherapy agents and experimental drugs, revealing promising results and shedding light on their effects.
A new study found that methylphenidate treatment improved sleep parameters in adults with ADHD, including increased sleep efficiency and a feeling of improved restorative value. The study also showed that objective and subjective sleep problems in adults with ADHD are identical to those in children with ADHD.
Researchers at UT Southwestern Medical Center have found that arsenic linked to a cancer-homing drug provides a powerful imaging agent for detecting hard-to-find tumors. The technique allows physicians to detect early tumor deposits and monitor cancer's response to therapy with clear images.
A new study found that stimulant treatment for children with ADHD has no effect on their future risk of substance abuse. The 10-year follow-up study analyzed over 100 young men and controlled for conditions like conduct disorder, which are associated with substance abuse.
A new international study has found that increasing the intensity of chemotherapy can reduce mortality rates for children with severe Langerhans cell histiocytosis (LCH) by up to 20 percent. The study, which involved 193 pre-identified patients, demonstrated a statistically significant improvement in prognosis and survival rates.
Researchers discovered that bats can generate a leading-edge vortex, increasing lift by up to 40%, allowing them to hover in mid-air. This finding challenges quasi-steady state aerodynamic theory and has implications for the design of slow-flying surveillance planes.
A study published in SLEEP found that children with obstructive sleep apnea (OSA) exhibit abnormal respiratory-related evoked potentials, indicating reduced protective responses to upper airway collapse. This may explain why children with OSA develop the condition despite normal arousals to non-respiratory stimuli.
A new study published in the journal Sleep reveals that narcolepsy patients have a high prevalence of eating disorders, with half reporting persistent cravings and binge eating. The study also found no correlation between weight gain and binge eating, suggesting metabolic alterations may be involved.
Loud snoring with breathing pauses is associated with an increased risk of hypertension, heart attacks, and strokes. Quiet snoring is linked only to an increased risk for hypertension in women. The study found that loud snoring carries a significantly increased risk for cardiovascular disease.
A study published in the journal SLEEP found that both insomnia patients and normal sleepers define sleep quality by tiredness upon waking and throughout the day. Individuals with insomnia have more requirements for judging sleep to be of good quality, including a greater need for restful nights and fewer allowed awakenings.
Researchers compared three leading dietary guides, finding consistent messages on eating more fruits, vegetables, and whole grains. A study also found that cancer survivors are more likely to use supplements, with a diagnosis of cancer being closely associated with vitamin use.
