Higher Preoperative Serum Neuropeptide Y Concentration May Be Associated with a Better Prognosis After Surgery for Colorectal Cancer.

Background: The early identification of patients at risk of peri-procedural complications and poor prognosis is particularly important. We conducted our study to determine whether serum orexigenic neuropeptide Y (NPY) concentration is associated with nutritional status and prognosis among patients undergoing surgery for colorectal cancer (CRC).

Materials And Methods: A cohort study with a 3-month follow-up was conducted with 84 consecutive inpatients who underwent elective surgery in one center between 2016 and 2019 for primary CRC.

Ex Situ Raman Mapping of LiMnO Electrodes Cycled in Lithium-Ion Batteries.

In this study, we focus on the large-scale ex situ Raman mapping of LiMnO (LMO) electrodes maintained at varying states of charge. A comprehensive statistical analysis has been conducted at an area of ca. 3660 μm on more than 3100 collected spectra for each LMO electrode sample.

Comparative study of photocatalysis with bulk and nanosheet graphitic carbon nitrides enhanced with silver.

The main goal of this research is to investigate the effectiveness of graphitic carbon nitride (g-CN, g-CN) in both bulk and nanosheet forms, which have been surface-modified with silver nanoparticles (Ag NPs), as photocatalysts for the degradation of acid orange 7 (AO7), a model dye. The photodegradation of AO7 dye molecules in water was used to test the potential photocatalytic properties of these powder materials under two different lamps with wavelengths of 368 nm (UV light) and 420 nm (VIS light). To produce Ag NPs (Ag content 0.

Optimizing Horticulture Luminescent Solar Concentrators via Enhanced Diffuse Emission Enabled by Micro-Cone Arrays.

Optimizing the photon spectrum for photosynthesis concurrently with improving crop yields presents an efficient and sustainable pathway to alleviate global food shortages. Luminescent solar concentrators (LSCs), consisting of transparent host matrices doped with fluorophores, show excellent promise to achieve the desired spectral tailoring. However, conventional LSCs are predominantly engineered for photon concentration, which results in a limited outcoupling efficiency of converted photons.
