Nitrate electroreduction reaction (NORR) to ammonia (NH) still faces fundamental and technological challenges. While Cu-based catalysts have been widely explored, their activity and stability relationship are still not fully understood. Here, we systematically monitored the dynamic alterations in the chemical and morphological characteristics of CuO nanocubes (NCs) during NORR in an alkaline electrolyte.

Objective: To analyze the effect of combined training (CT) in postural control and gait parameters in postmenopausal women.
Methods: A parallel-group, randomized, control study was conducted with 16 weeks of combined training ( = 16) versus a non-training control group ( = 12) in postmenopausal women (aged 59.3 ± 8.
Unlabelled: Circulating tumor cells (CTCs) and/or circulating tumor microemboli (CTM) from non-small cell lung cancer (NSCLC) patients may be a non-invasive tool for prognosis, acting as liquid biopsy. CTCs interact with platelets through the transforming growth factor-β/transforming growth factor-β receptor type 1 (TGF-β/TGFβRI) forming clusters. CTCs also may express the Cluster of Differentiation 47 (CD47) protein, responsible for the inhibition of phagocytosis, the "don't eat me" signal to macrophages.

Leishmaniasis is a parasitic disease found in tropical and subtropical regions around the world, caused by parasites of the genus Leishmania. The disease is a public health concern and presents clinical manifestations that can cause death, disability, and mutilation. The parasite has promastigote (vector) and amastigote (vertebrate host) forms and kinase enzymes are involved in this differentiation process.

In this study, we evaluated the direct impact of the different percentages of CNC on pectin hydrogel and the influence of HAp obtained through two methods. CNC were obtained from HCl hydrolysis following chemical functionalization through vinyl groups.
