COPD: Iron Deficiency and Clinical Characteristics in Patients With and Without Chronic Respiratory Failure.

Background: The prevalence of iron deficiency in patients with chronic obstructive pulmonary disease (COPD) varies in previous studies. We aimed to assess its prevalence according to 3 well-known criteria for iron deficiency, its associations with clinical characteristics of COPD, and mortality.

Methods: In a cohort study consisting of 84 COPD patients, of which 21 had chronic respiratory failure, and 59 were non-COPD controls, ferritin, transferrin saturation (TSat), and mortality across 6.

Systematic rare Earth doping to adopt an 32 type huntite structure in NdSc(BO) crystals.

This study is focused on determining the type and quantity of REE impurities responsible for converting the structure of NdSc(BO) into an 32 polymorph. According to the single crystal X-ray diffraction of RNdSc(BO) (R = Sm-Lu, + + = 4) the samples probably contain several polymorphic modifications. However, the predominant structure has been defined as 32 for R = Eu, Er, Tm, and Yb and 321 for R = Sm, Gd, Tb, Dy, and Ho.

Autophagy and vesicular trafficking in human uveal melanoma: A histopathological study.

Uveal melanoma is an ocular tumor with a high risk of developing metastases. The endo-lysosomal system can affect the melanoma progression by accelerating and facilitating invasion or metastasis. This study aims to conduct comparative analysis of normal choroidal melanocytes and uveal melanoma cells ultrastructure with a focus on intracellular transport system, and to examine the patterns of autophagy- and vesicular trafficking-related proteins expression in a case series of uveal melanomas.

It is unlikely that oxygen supplementation in COPD patients with chronic respiratory failure reduce cardiac troponin level.

Background: Cardiac troponin T (cTnT) is a biomarker of myocardial injury frequently elevated in COPD patients, potentially because of hypoxemia. This non-randomised observational study investigates whether long-term oxygen treatment (LTOT) reduces the cTnT level.

Methods: We compared cTnT between COPD patients who were candidates for LTOT (n = 20) with two reference groups.

Synthesis and Growth of Rare Earth Borates NaSrR(BO) (R = Ho-Lu, Y, Sc).

NaSrR(BO) (R = Ho-Lu, Y, Sc) compounds were obtained for the first time. Their structures exhibit disordered positions of Sr and Na atoms while RO polyhedra are connected through the BO groups. Large distances between R atoms and high transparency in the range of 250-900 nm make them promising for phosphor applications.
