One of the main reasons we have not been able to cure cancers is that treatments select for drug-resistant cells. Pest managers face similar challenges with pesticides selecting for pesticide-resistant insects, resulting in similar mechanisms of resistance. Pest managers have developed 10 principles that could be translated to controlling cancers: (i) prevent onset, (ii) monitor continuously, (iii) identify thresholds below which there will be no intervention, (iv) change interventions in response to burden, (v) preferentially select nonchemical control methods, (vi) use target-specific drugs, (vii) use the lowest effective dose, (viii) reduce cross-resistance, (ix) evaluate success based on long-term management, and (x) forecast growth and response.

Fruit and vegetable intake (FVI), moderate-to-vigorous physical activity (MVPA), and sleep duration are each independently associated with cancer-related and general health outcomes among cancer survivors. Past research suggests that health behaviors cluster among cancer survivors, with caregivers demonstrating similar patterns. This analysis examined co-occurrence of FVI, MVPA, and sleep duration among cancer survivors and informal cancer caregivers and identified sociodemographic and clinical correlates of health behavior engagement.

  • 2-Arachidonoylglycerol (2-AG) is a chemical in the brain that helps keep it balanced and healthy.
  • Researchers found that blocking the enzyme that breaks down 2-AG can help with brain diseases, but focusing only on the neurons can actually hurt learning and memory in mice.
  • The study shows that too much 2-AG in neurons can harm brain connections, but balancing it with help from other brain cells called astrocytes can improve cognitive function.

Article Synopsis
  • The study aimed to measure the impact of plate shape (curvilinear vs. linear) on deltoid muscle disruption during surgery for proximal humeral fractures.
  • Using cadaveric shoulders, researchers tested 4 different plate types and found that the curvilinear plate required significantly less deltoid release compared to the linear plates.
  • Results showed a clear correlation between plate length and the level of deltoid disruption, indicating that both plate shape and length play a role in minimizing muscle damage during surgical procedures.

Mitochondria as a primary determinant of angiogenic modality in pulmonary arterial hypertension.

J Exp Med

November 2024

Division of Pulmonary, Critical Care, Sleep and Occupational Medicine, Department of Medicine, Indiana University, Indianapolis, IN, USA.

Impaired pulmonary angiogenesis plays a pivotal role in the progression of pulmonary arterial hypertension (PAH) and patient mortality, yet the molecular mechanisms driving this process remain enigmatic. Our study uncovered a striking connection between mitochondrial dysfunction (MD), caused by a humanized mutation in the NFU1 gene, and severely disrupted pulmonary angiogenesis in adult lungs. Restoring the bioavailability of the NFU1 downstream target, lipoic acid (LA), alleviated MD and angiogenic deficiency and rescued the progressive PAH phenotype in the NFU1G206C model.
