Fully automated segmentation of brain and scalp blood vessels on multi-parametric magnetic resonance imaging using multi-view cascaded networks.

Background And Objective: Neurosurgical navigation is a critical element of brain surgery, and accurate segmentation of brain and scalp blood vessels is crucial for surgical planning and treatment. However, conventional methods for segmenting blood vessels based on statistical or thresholding techniques have limitations. In recent years, deep learning-based methods have emerged as a promising solution for blood vessel segmentation, but the segmentation of small blood vessels and scalp blood vessels remains challenging.

Effect of Anterior Chamber Air Injection on Intraocular Lens Stability after Phacovitrectomy with Gas/Air Tamponade.

Purpose: Anterior chamber air injection (ACAI) is a surgical technique used to decrease the occurrence of postoperative intraocular lens (IOL) haptic dislocation following phacovitrectomy with gas/air tamponade. The impact of this technique on IOL stability remains uncertain, prompting the design of this study to investigate further.

Methods: This study included 51 eyes of 51 patients who underwent phacovitrectomy with gas/air tamponade.

LBNP: Learning features between neighboring points for point cloud classification.

Inspired by classical works, when constructing local relationships in point clouds, there is always a geometric description of the central point and its neighboring points. However, the basic geometric representation of the central point and its neighborhood is insufficient. Drawing inspiration from local binary pattern algorithms used in image processing, we propose a novel method for representing point cloud neighborhoods, which we call Point Cloud Local Auxiliary Block (PLAB).

Efficacy and mechanism of cyprosulfamide in alleviating the phytotoxicity of clomazone residue on maize seedling.

Introduction: The residues of clomazone (Clo) can lead to phytotoxic symptoms such as foliar bleaching, reduced plant height, and decreased maize yields. Herbicide safener represent one of the most economically efficient strategies for mitigating herbicide-induced damage.

Methods: In this study, various seed treatments were implemented, including the immersion of maize seeds in water (CK), immersion in Cyprosulfamide (CSA), soil supplemented with clomazone (ClO) and CSA+ClO, evaluated physiological indicators, chlorophyll content, and qRT-PCR analyses of the maize plants were evaluated under the different treatments.

Global, regional, and national burden of myocarditis in children aged 0-14 years, 1990-2021: analysis for the global burden of disease study 2021.

Objective: There are limited epidemiological data on myocarditis in children aged 0-14 years. This study aims to investigate the trends in incidence, mortality, disability-adjusted life years (DALYs), and corresponding estimated annual percentage change (EAPC) of myocarditis in children aged 0-14 years from 1990 to 2021.

Methods: We utilized the 2021 Global Burden of Disease, Injuries, and Risk Factors Study (GBD) analytical tools to examine the incidence, mortality, and DALYs of myocarditis in children aged 0-14 years, considering factors such as age, sex, region, sociodemographic index (SDI), and data from 204 countries or regions.
