DNA repair activity may be associated with risk of lung cancer

Measuring DNA repair enzyme OGG activity found a significant association with lung cancer risk. Smokers and nonsmokers with low OGG activity had higher lung cancer risk compared to those with normal activity levels, with smokers being at greater risk due to smoking alone.

World first for Swedish researchers – mice born from transplanted wombs

Researchers have successfully transplanted uteri into mice, paving the way for future womb transplants in humans. The study found that transplanted uteri can harbour pregnancies and rejection patterns are similar to other organs.

A new view of the crayfish brain

Researchers at Emory University Health Sciences Center have developed a new MRI technique using manganese-enhanced imaging to study the neural circuitry of aggression in crayfish. This breakthrough enables scientists to analyze entire patterns of brain activation, providing insights into complex social behaviors.

FOSRENOL (TM) (lanthanum carbonate) shows favourable effects in 12-month bone biopsy study

A 12-month study comparing FOSRENOL and calcium carbonate found that FOSRENOL led to a 'considerably better outcome' on bone histology, with halved rates of patients with osteomalacia, adynamic bone disease, or hyperparathyroidism. This contrasts with the calcium carbonate group, which showed an increase in these conditions.

Other highlights of the April 16 JNCI

A study published in the Journal of the National Cancer Institute found that only 40% of patients with superficial bladder cancer had regular follow-up examinations, despite recommended guidelines. Patient characteristics such as age, ethnicity, and socioeconomic status were independently associated with low-intensity surveillance.

New genetic screening method predicts behaviour of Wilms' tumour in children

A new genetic screening method has been developed to predict the behaviour of Wilms' tumour in children. Genes on chromosome 1q are overexpressed in tumours that relapse, suggesting that identifying subgroups at presentation could improve treatment outcomes.

Ovarian carcinoma, ethnicity, and survival

Research found that African-American women with ovarian cancer are at a 30% increased risk of death from any cause compared to Caucasian women. The study also revealed significant differences in tumor stage, lymph node involvement, and surgery rates between the two ethnic groups. Median survival times were also shorter for African-Amer...

Malnutrition In AIDS Patients

Researchers investigated enteral supplements' impact on AIDS patients, finding net increases in protein and energy intakes. However, fat-free mass did not increase for the group as a whole, but was inversely correlated with baseline synthesis of fat.
