Assessing smoking-cessation programs – Does the 5A program work?

A comprehensive assessment of smoking cessation services found substantial clinician compliance with guidelines, with most smokers reporting they wanted doctors to discuss cessation at medical visits. However, only a third of motivated smokers asked for help, highlighting the need for improved patient engagement and encouragement.

Regular yoga practice may help prevent middle-age spread

A study of 15,500 middle-aged men and women found that regular yoga practice was associated with a lower weight gain between ages 45 and 55. Those who were already normal weight at age 45 and practiced yoga regularly lost about 3 fewer pounds compared to non-practitioners.

Biased reporting found in cancer prognostic studies

A study analyzed data from 18 published studies on TP53 protein and mortality rates, finding selective reporting biases that may have fabricated strong associations. The authors caution that the findings highlight limitations of current research methods and call for more transparent reporting and better study design.

Study reveals trigger for insulin resistance in liver, potential drug targets

A recent study has identified mitochondrial acyl-CoA:glycerol-sn-3-phosphate acyltransferase 1 (mtGPAT1) as a trigger for insulin resistance in the liver. The researchers found that mice lacking this enzyme were protected from fatty liver and liver insulin resistance, suggesting mtGPAT1 as a potential therapeutic target.

Insulin pulses keep the liver lean

New study reveals that acute insulin pulses limit fat synthesis in the liver by activating a key molecule called CEACAM1. Regular periods of fasting between meals help maintain a healthy liver by allowing insulin levels to fluctuate.

UCI researchers define estrogen's role in limiting heart disease in women

Researchers found that estrogen triggers molecular activity blocking cardiac hypertrophy, a common cause of heart enlargement and heart failure. The study suggests that estrogen supplements may prevent cardiac hypertrophy in postmenopausal women, continuing a debate on the hormone's role in limiting cardiovascular disease.

Object recognition improves when other objects appear in the same orientation

Researchers found that recognizing familiar objects is easier when they appear at the same angle, as this allows for temporary adjustments to the coordinate system. This can lead to improved recognition of misoriented objects, such as a dog shown in the same orientation as another object.
