Robust Fluorescent Nanoprobe for Rapid Evaluation of the Selenium Supplementation Effect and Imaging.

At present, an increasing number of people pay more attention to selenium-enriched food, but the quality of the selenium-enriched food varies. Therefore, there is an urgent need to develop a new tool to assess the effects of selenium supplementation in foods by rapidly detecting the levels of the metabolite selenium selenocysteine (Sec). In this work, a fluorescent nanoprobe was designed, synthesized, and characterized for Sec detection and imaging in living biosystems, which exhibited the advantages of good biocompatibility, excellent water solubility, high sensitivity, high selectivity, and rapid response (2.

Activatable fluorescent probes for early diagnosis and evaluation of liver injury.

With the increase in people's living standards, the number of patients suffering from liver injury keeps on increasing. Traditional diagnostic methods can no longer meet the needs of early and accurate diagnosis due to their limitations in application. However, fluorescent probes based on different fluorophores and nanomaterials have been gradually lighting up medical research due to their unique properties, such as high specificity and non-invasiveness.

The GPIHBP1-LPL complex and its role in plasma triglyceride metabolism: Insights into chylomicronemia.

GPIHBP1 is a protein found in the endothelial cells of capillaries that is anchored by glycosylphosphatidylinositol and binds to high-density lipoproteins. GPIHBP1 attaches to lipoprotein lipase (LPL), subsequently carrying the enzyme and anchoring it to the capillary lumen. Enabling lipid metabolism is essential for the marginalization of lipoproteins alongside capillaries.

Long non-coding RNA MALAT1 sponges miR-149 to promote inflammatory responses of LPS-induced acute lung injury by targeting MyD88.

Acute lung injury (ALI) caused by sepsis occurs early and the condition is severe, and is also an important reason for accelerating the death of patients. Increasing evidence has identified long non-coding RNA (lncRNA) metastasis associated in lung adenocarcinoma transcript 1 (MALAT1) as a regulator of ALI. However, the potential mechanism underlying MALAT1 on ALI still needs further identification.

Fast Cross-Validation for Kernel-Based Algorithms.

Cross-validation (CV) is a widely adopted approach for selecting the optimal model. However, the computation of empirical cross-validation error (CVE) has high complexity due to multiple times of learner training. In this paper, we develop a novel approximation theory of CVE and present an approximate approach to CV based on the Bouligand influence function (BIF) for kernel-based algorithms.

[Diagnostic value of different detection methods for Mycobacterium tuberculosis in bronchoalveolar lavage fluid from pulmonary tuberculosis patients].

To investigate the diagnostic value of different detection methods for Mycobacterium tuberculosis in bronchoalveolar lavage fluid (BALF) from patients with pulmonary tuberculosis.
 Methods: BALF from100 patients in Changsha Central Hospital from January 2013 to December 2015 was collected. Among 100 patients, 65 cases were clinically diagnosed as tuberculosis, and 35 cases served as control.
