Inflammatory bowel disease (IBD) is a recurrent bowel disease that usually requires magnetic resonance enterography (MRE) for diagnosis and monitoring. However, recognition of bowel segments from MRE images by a radiologist is challenging and time-consuming. Deep learning-based medical image segmentation has shown the potential to reduce manual effort and provide automated tools to assist in disease management; however, it requires a large-scale fine-annotated dataset for training.

The combined toxicity of antibiotics and their regulatory effects on microorganisms are areas that warrant significant attention. In this study, doxycycline hydrochloride (DXC), sulfamethoxazole (SMX) and sulfamethazine (SMZ) were used as the research objects, and Scenedesmus obliquus was used as the indicator organism to study their toxicity and action laws at different exposure times (4d and 8d).

This retrospective study analyzed the clinical data of 159 children with eczema admitted to the hospital from May 2023 to October 2024 as the experimental group. The patients were divided into groups according to the severity of the disease: mild group(≤ 25 points, n = 45), moderate group(25-50 points, n = 72) and severe group(>50 points, n = 42).

This study aimed to elicit preferences regarding HIV testing among community residents to identify a model of community-based HIV testing services that would appeal to this population.
Methods: A discrete-choice experiment (DCE) was conducted in the communities of Yunnan Province, China.
Pillar stability has garnered significant attention owing to the effects of pillars on coal resource recovery rate, coal pillar stability, and coal bump risk. This study examined the roadway stability control principles of conventional and yield coal pillars. The conventional coal pillars were designed as load-bearing structures with a high load-bearing capacity to carry most of the abutment load, while yield coal pillars were designed as buffer structures for transferring rapidly increasing abutment loads to adjacent solid coal ribs by progressive deformation.

While the compilation of predictive descriptors is pivotal for in silico model development, key features specifically tailored for predicting lung fibrosis remain elusive. This study aimed to uncover the essential predictive descriptors governing nanoparticle-induced pulmonary fibrosis.

Our previous study found that polyether K-41A and its analog K-41Am, derived from a marine Streptomyces strain, exhibit anti-HIV activity by suppressing the activities of HIV-1 reverse transcriptase (RT) and its integrase (IN). Among the K-41A derivatives, two disaccharide-bearing polyethers-K-41B and K-41Bm-were found to have potent anti-HIV-1 activity in vitro.

Objective: To conduct a comprehensive review of reversible factors associated with breast cancer, with the aim of offering insights for the creation of early intervention strategies for breast cancer prevention.
Methods: The PubMed, EMBASE, and Scopus databases were systematically searched to collect systematic reviews and meta-analyses related to breast cancer risk. Searches were limited to literature published from the inception of each database up to May 1, 2024.
Background: Acute pulmonary embolism (APE) is a critical disease with a high mortality rate, some of the surviving patients may develop chronic thromboembolic pulmonary disease (CTEPD), which affects the patient's prognosis. However, the research on the early diagnosis of CTEPD is limited. This study aimed to establish a prediction model for earlier identification of CTEPD.

While analyses are commonly employed for chemical risk assessments, predicting chronic lung toxicity induced by engineered nanoparticles (ENMs) still faces many challenges due to complex interactions at multiple nanobio interfaces. In this study, we developed a rigorous method to compile published evidence on the lung toxicity of metal oxide nanoparticles (MeONPs) and revealed previously overlooked -to- extrapolation (IVIVE) relationships. A comprehensive multidimensional data set containing 1102 data points, 75 pulmonary toxicological biomarkers, and 20 features (covering effects, physicochemical properties, and exposure conditions) was constructed.

We aimed to develop a VAT fingerprint index (VAT-FI) using radiomics and deep learning features extracted from computed tomography (CT) images of 1,135 CD patients across six hospitals (training cohort, = 600; testing cohort, = 535) for predicting BD, and to compare it with a subcutaneous adipose tissue (SAT)-FI. VAT-FI exhibited greater predictive accuracy than SAT-FI in both training (area under the receiver operating characteristic curve [AUC] = 0.

In this article, a pruning idea of routing integrated with Dijkstra's shortest path searching is utilized to accelerate the process of routing in large-scale multi-domain elastic optical networks (EONs). The layered-graph approach is adopted in the spectrum allocation stage.

Management of giant complex thrombosed aneurysms of the middle cerebral artery (MCA) is challenging. Most giant MCA aneurysms possess some unfavorable features, such as incorporation of key MCA branches, efferent or perforating vessels originating from the sac, mural calcifications, intraluminal thrombi, or fusiform configurations. Due to these peculiar features, traditional clipping or simple endovascular coiling is generally not able to treat these aneurysms.

Deleting the mechanosensitive ion channel Piezo1 from Dmp1-Cre-targeted cells, which include both osteoblasts and osteocytes, resulted in reduced bone mass and impaired skeletal responses to mechanical stimuli. To specifically isolate Piezo1's role in osteocytes, we used Sost-Cre mice to generate mice with Piezo1 deletion exclusively in mature osteocytes.

We investigated the potential application of deep learning reconstruction (DLR) in CTE to reduce radiation dose and improve image quality in IBD.
Methods: Thirty-six patients with known or suspected IBD were prospectively recruited to the low-dose CTE (LDCTE) group, while forty patients were retrospectively selected from previous clinical standard-dose CTE (STDCTE) scans as controls.
The limited number of organic micropollutants (OMPs) investigated in aquaculture seawater may underestimate the risk to marine organisms. It is critical to comprehensively investigate the occurrence of diverse OMPs in mariculture area and assess their joint risks to coastal marine organisms. Herein, the joint risks caused by multiple substances were assessed based on the screened results of approximately 1300 non-polar to polar OMPs in the seawater of mariculture ponds and raft culture areas around Liaodong Peninsula.
