Article Synopsis
- Dyslipidemia is a common health issue linked to various diseases, with a notable connection to ferroptosis, which is driven by iron levels in the body.
- A study conducted in Taizhou, China, involving 1,917 residents, found a significant positive correlation between whole blood iron levels and parameters such as total cholesterol, triglycerides, and low-density lipoprotein cholesterol, particularly in men.
- The findings suggest that managing whole blood iron levels could be an effective strategy for controlling dyslipidemia, especially in terms of triglycerides and cholesterol among the population.
Objective: To estimate proton density fat fraction (PDFF) from chemical shift encoded (CSE) MR images using a deep learning (DL)-based method that is precise and robust to different MR scanners and acquisition echo times (TEs).
Methods: Variable echo times neural network (VET-Net) is a two-stage framework that first estimates nonlinear variables of the CSE-MR signal model, to posteriorly estimate water/fat signal components using the least-squares method. VET-Net incorporates a vector with TEs as an auxiliary input, therefore enabling PDFF calculation with any TE setting.
Article Synopsis
- This study investigated how physiological status (PS) and days of pregnancy (DOP) impact weight changes, food intake, and digestion in beef heifers, using 12 zebu heifers (7 pregnant and 5 non-pregnant).
- Over the course of the study, pregnant heifers gained body reserves initially but lost weight later; their dry matter and organic matter intake increased with pregnancy, while some digestibility measures decreased.
- Key findings include higher crude protein digestibility in later stages of pregnancy compared to non-pregnant heifers, along with lower overall digestibility of certain components in pregnant heifers.
Purpose: To describe an experimental surgical model in rats using a dual-plane technique for evaluation of biomaterials in an in-vivo silicone implant coverage.
Methods: This study was developed following the ISO 10993-6 standard. In this study, 40 male Wistar rats weighing between 250 and 350 g were used, distributed into two groups: experimental, biomaterial superimposed on the minimammary prosthesis (MP); and control, MP without implantation of the biomaterial, with eight animals at each biological point: 1, 2, 4, 12, and 26 weeks.
This study aimed to evaluate the effects of a blend of different sources of magnesium oxide associated or not with monensin, on productive, ruminal, and nutritional parameters of steers. Eighty-four Nellore steers with an initial body weight (BW) of 367.3 ± 37.
