Thiourea-Mediated Stereospecific Deoxygenation of Cyanoepoxides to Access Highly Diastereopure Alkenyl Nitriles
A practical and efficient protocol
for synthesis of >99% diastereopure Z- and E-alkenyl nitriles is developed,
through tetramethylthiourea-mediated stereospecific deoxygenation
of respective cis- and trans-cyanoepoxides
in ethanol. The desired products are obtained in excellent yields

Prediction of Poor Prognosis in Breast Cancer Patients Based on MicroRNA-21 Expression: A Meta-Analysis
<div><p>Background</p><p>MicroRNA-21 (miRNA-21 or miR-21) may act as a prognostic biomarker of cancer. However, the available evidence is controversial. Therefore, the present meta-analysis summarizes this evidence and evaluates the prognostic role of this gene in breast cancer.</p><p>Methods</p><p>The meta-analysis was conducted by searching the databases of PubMed, EMBASE, Web of Science and Chinese database-China National Knowledge Infrastructure (CNKI). Data were extracted from studies that investigated the association between miR-21 expression and survival outcomes in breast cancer patients. With respect to survival outcomes, the pooled hazard ratios (HRs) of miR-21 were calculated given a 95% confidence interval (CI).</p><p>Results</p><p>Our meta-analysis identified a total of 10 studies involving 1,439 cases. Further investigation demonstrated that a high miR-21 expression can predict poor overall survival (OS) (HR = 2.57, 95% CI: 1.37—4.81, <i>P</i> = 0.003) and shortened disease-free/recurrence-free survival (DFS/RFS) (HR = 1.45, 95% CI: 1.16—1.82, <i>P</i> = 0.001) in breast cancer patients. Moreover, high miR-21 expression was significantly correlated with lowered OS in the Asian group (HR = 5.07, 95% CI: 2.89—8.92, <i>P</i> < 0.001), but not in the Caucasian cohort (HR = 1.44, 95% CI: 0.99—2.10, <i>P</i> = 0.058). Furthermore, odds ratios (ORs) showed that up-regulated miR-21 levels were associated with multiple clinical characteristics.</p><p>Conclusion</p><p>Our results indicated that miR-21 can predict unfavorable prognoses in breast cancer patients, especially in Asians.</p></div
Noninvasive Gastrointestinal Tract Imaging Using BSA-Ag<sub>2</sub>Te Quantum Dots as a CT/NIR-II Fluorescence Dual-Modal Imaging Probe in Vivo
The combination of high-resolution computed tomography
(CT) and
the real-time sensitive second near-infrared window (NIR-II) fluorescence
bioimaging can provide complementary information for the diagnosis,
progression and prognosis of gastrointestinal disorders. Ag2Te quantum dots (QDs) are a kind of promising CT/NIR-II fluorescence
dual-modal imaging probe due to their high atomic number and narrow
bandgap. However, conventional Ag2Te QDs synthesized by
oil phase approaches often suffer from complicated steps, harsh reaction
conditions, and toxic organic solvents. Herein, we report the synthesis
of bovine serum albumin (BSA)-Ag2Te QDs using a biomineralization
approach for CT/NIR-II fluorescence dual-modal imaging of the gastrointestinal
tract. The BSA-Ag2Te QDs are fabricated in a facile one-pot
approach under mild conditions and exhibit homogeneous size, favorable
monodispersity, admirable aqueous solubility, excellent X-ray attenuation
properties, and outstanding NIR-II fluorescence performance. In vivo
imaging experiments show that BSA-Ag2Te QDs can be used
in gastrointestinal tract CT/NIR-II dual-modal imaging with high spatiotemporal
resolution and sensitivity. In addition, in an intestinal obstruction
mouse model, accurate lesion positioning and imaging-guided obstruction
relief surgery are successfully realized based on BSA-Ag2Te QDs. Besides, BSA-Ag2Te QDs have outstanding biocompatibility
in vitro and in vivo. This study presents a high-performance and biosafe
CT/NIR-II fluorescence dual-modal imaging probe for visualizing the
gastrointestinal tract in vivo
