Construction of Isoquinolone Scaffolds on DNA via Rhodium(III)-Catalyzed C-H Activation.

Isoquinolone is one of the most common heterocyclic core structures in countless natural products and many bioactive compounds. Here, a highly efficient approach to synthesize isoquinolone scaffolds on DNA via rhodium(III)-catalyzed C-H activation has been described. This chemistry transformation is robust and has shown good compatibility with DNA, which is suitable for DNA-encoded library synthesis.

Iodine-Catalyzed Aerobic Oxidation of Spirovinylcyclopropyl Oxindoles to Form Spiro-1,2-dioxolanes Diastereoselectively.

A novel method of iodine-catalyzed aerobic oxidation with spirovinylcyclopropyl oxindoles under mild conditions has been described. A series of spiro-1,2-dioxolanes were prepared in good to excellent yields and considerable diastereoselectivities. The new approach is operationally simple, scalable, and tolerant of various functional groups.

Application of a clustered countercurrent-flow micro-channel reactor in the preparation of KMnF perovskite for asymmetric supercapacitors.

A clustered countercurrent-flow micro-channel reactor (C-CFMCR) with adjustable magnification times was constructed for the preparation of KMnF perovskite fluoride by a co-precipitation process, in which the concentrations and feed rates of reactants were precisely controlled. Benefitting from the enhanced micromixing efficiency of the microreactor, the KMnF particles prepared in C-CFMCR were smaller and less aggregated than those produced with traditional stirred reactors (STR). The prepared KMnF was applied as the electrode material in supercapacitors, and the electrochemical measurements showed that the KMnF obtained under optimal conditions had a discharge specific capacitance of ∼442 F g at a current density of 1 A g, with a decline of ∼5.

Application of micro-impinging stream reactors in the preparation of Co and Al co-doped Ni(OH) nanocomposites for supercapacitors and their modification with reduced graphene oxide.

A micro-impinging stream reactor (MISR) consisting of a commercial T-junction and steel capillaries, which is of intensified micromixing efficiency as compared with traditional stirred reactors (STR), was applied for the preparation of Co and Al co-doped Ni(OH) nanocomposites and their modification with reduced graphene oxide (RGO). The co-precipitation preparation process was conducted under precisely controlled proportions and concentrations of reactants in the MISR. Therefore, element analysis showed a higher uniform distribution of metal ions within the nanocomposites obtained through the MISR.

Micromixing Study of a Clustered Countercurrent-Flow Micro-Channel Reactor and Its Application in the Precipitation of Ultrafine Manganese Dioxide.

A clustered countercurrent-flow micro-channel reactor (C-CFMCR) has been assembled by the numbering-up of its single counterpart (S-CFMCR). Its micromixing performance was then studied experimentally using a competitive parallel reaction system, and the micromixing time was calculated as the micromixing performance index. It was found that the micromixing time of C-CFMCR was ranged from 0.

Synthesis and cytotoxicity evaluation of 3-amino-2-hydroxypropoxygenistein derivatives.

Soy isoflavones exhibit various biological activities, such as antioxidant, anti-tumor, anti-inflammatory, and cardiovascular protective effects. The present study was designed to investigate the effects of sixteen synthesized 3-amino-2-hydroxypropoxy genistein derivatives on cell proliferation and activation of Nrf2 (Nuclear factor erythroid 2-related factor 2)/ARE (antioxidant response elements) pathway in human cancer cell lines. Most of the tested compounds exerted greater cytotoxic activity than genistein, as measured by MTT assay.

X-11-5-27, a daidzein derivative, inhibits NLRP3 inflammasome activity via promoting autophagy.

NLRP3 inflammasome is a cytoplasmic multiprotein complex which plays a critical role in response to infection or injury, however, aberrant NLRP3 inflammasome activation is deleterious. In our study, we investigate the inhibitory effect of X-11-5-27, a daidzein derivative, on the NLRP3 inflammasome. The results showed that the activation of NLRP3 inflammasome was inhibited by X-11-5-27 in a dose-dependent manner, followed by a decrease in the cleavage of caspase-1 and maturation of IL-1β.

Uniportal video-assisted thoracoscopic lobectomy: An alternative surgical method for pulmonary carcinoma.

Objectives: To explore the effects and feasibility of single-port video-assisted thoracic surgery (VATS) on lobectomy for pulmonary carcinoma.

Methods: A total of 67 patients were enrolled in this study, in which 21 patients were treated by single-port VATS (Sing-port Group) and 46 patients by double-port VATS (Double-port Group). Blood loss, duration of thoracic drainage, length of post-operative hospital stay and post-operative pain ratings were compared between the two groups.

Thoracoscopic excision of two bronchogenic cysts located in highest upper mediastinum: Report of two cases.

Bronchogenic cysts are rare congenital malformation that need surgical removal. To date, bronchogenic cysts located in highest upper mediastinum excised by thoracoscopy have not been reported, though complete thoracoscopic extirpation of a bronchogenic cyst has been reported before. We excised two highest upper bronchogenic cysts by thoracoscopy successfully without any postoperative complication, demonstrating thoracoscopy could be a first-line therapeutic option even for highest upper mediastinum brochogenic cysts.
