Lunar Lithium-7 Sensing (7Li): Spectral Patterns and Artificial Intelligence Techniques.

Lithium, a critical natural resource integral to modern technology, has influenced diverse industries since its discovery in the 1950s. Of particular interest is lithium-7, the most prevalent lithium isotope on Earth, playing a vital role in applications such as batteries, metal alloys, medicine, and nuclear research. However, its extraction presents significant environmental and logistical challenges.

Stromal markers of activated tumor associated fibroblasts predict poor survival and are associated with necrosis in non-small cell lung cancer.

Objectives: Tumor associated fibroblasts (TAFs) are essential contributors of the progression of non-small cell lung cancer (NSCLC). Most lung TAFs exhibit an activated phenotype characterized by the expression of α-SMA and fibrillar collagens. However, the prognostic value of these activation markers in NSCLC remains unclear.

Spontaneous pneumomediastinum in a patient with facial rash.

A 38-year-old male nonsmoker presented with constitutional symptoms, polyarthritis, facial rash, and progressive dyspnea of more than 1-year duration. Chest radiology revealed bilateral reticular and ground glass infiltrates. Connective tissue disease investigation was unrevealing.

Lung cancer survival in Spain and prognostic factors: a prospective, multiregional study.

Lung cancer survival varies greatly from one European country to another. Differences in data collection may account for some of the variations observed. The aim of this work was to ascertain the survival rate in diverse Spanish regions and to analyse the influence of age and other prognostic factors.

Association between habitual naps and sleep apnea.

Study Objectives: Taking an afternoon nap (siesta) is a common habit. A number of studies have shown an increased cardiovascular mortality in habitual nappers. Afternoon nappers have anthropometric characteristics similar to those of patients with sleep apnea.
