Summary of the best evidence for preventing the occurrence of subcutaneous emphysema in laparoscopic surgery.

To retrieve, analyze, and extract evidence related to subcutaneous emphysema in patients undergoing laparoscopic surgery systematically, and provide evidence-based recommendations for reducing its incidence. By browsing the websites of the National Institute for Health and Clinical Excellence, the International Guideline Collaboration Network, the National Guideline Library of the United States, the Registered Nurses Association of Ontario, the Scottish Intercollegiate Guideline Network, the Clinical Practice Guidelines website of the Canadian Medical Association, UpToDate, Web of Science, PubMed, OVID, Cochrane Library, Embase, Chinese Biomedical Database, CNKI, VIP, and Wanfang Database, relevant literatures, guidelines, systematic reviews, evidence summaries, expert consensus, randomized controlled trials, etc. about subcutaneous emphysema in patients undergoing laparoscopic surgery were retrieved.

Crystal structure, assembly process, and single-molecule magnet behavior of a triangular prismatic {Co} cluster.

Using the polydentate ligand of HL with the Co ion, a triangular prism-type nine-nucleus cluster [Co(L)(CHOCHOH)]·3.5HO ({Co9}-Eg, HL = 6,6'-(1,1'-[3,3'-bi(1,2,4-triazole)]-5,5'-diyl)dipicolinic acid) was constructed. Ion fragmentation during the formation of the {Co9}-Eg cluster was tracked using time-dependent electrospray ionization mass spectrometry.

Lactulose attenuates METH-induced neurotoxicity by alleviating the impaired autophagy, stabilizing the perturbed antioxidant system and suppressing apoptosis in rat striatum.

Methamphetamine (METH) is a widely abused psychostimulant. Lactulose is a non-absorbable sugar, which effectively decreases METH-induced neurotoxicity in rat. However, the exact mechanisms need further investigation.

Methamphetamine induces hepatotoxicity via inhibiting cell division, arresting cell cycle and activating apoptosis: In vivo and in vitro studies.

Methamphetamine (METH) resulted in acute hepatic injury. However, the underlying mechanisms have not been fully clarified. In the present study, rats were treated with METH (15 mg/kg B.

Solvent effects on the structures and magnetic properties of two doubly interpenetrated metal-organic frameworks.

Two doubly interpenetrated coordination polymers [Co2(BDC)2(bpt)2]·nSolvent based on dimeric secondary building units and crystallizing with distinct solvent molecules (-H2O and -MeOH for nSolvent = 2H2O and MeOH·H2O, respectively) were obtained by employing 1,4-benzenedicarboxylate (BDC) and 1H-3,5-bis(4-pyridyl)-1,2,4-triazole) (bpt) as linkers. The structures consist of a square grid of dimers bridged by BDC and pillared by bpt. Thermogravimetry and PXRD indicate that the frameworks are stable and are retained up to 400 °C, but the structures are modified irreversibly.

Samarium(III)-catalyzed C(sp3)-H bond activation: synthesis of indolizines via C-C and C-N coupling between 2-alkylazaarenes and propargylic alcohols.

A new rare earth metal and samarium-catalyzed C(sp(3))-H bond activation is reported in which 2-alkylazaarenes and propargylic alcohols were converted to indolizines. This process operates under mild conditions and solvent-free conditions. A broad scope of coupling partners has been established, and a likely mechanism has also been suggested.

Diaqua-bis(2,2'-biimidazole)cobalt(II) 4,4'-dicarboxy-biphenyl-3,3'-di-car-boxylate.

In the title compound, [Co(C(6)H(6)N(4))(2)(H(2)O)(2)](C(16)H(8)O(8)), the Co(II) cation and the organic anion occupy different crystallographic inversion centres and, as a consequence, the asymmetric unit comprises two half-mol-ecules. The benzene groups are coplanar. The four coordinating N atoms of the two bidentate biimidazole ligands define the equatorial plane of a slightly distorted octa-hedral CoO(2)N(4) geometry, and the water O atoms lie in the axial coordination sites.
