Cultural adaptation has become central in the context of accelerated global change with authors increasingly acknowledging the importance of understanding multilevel processes that operate as adaptation takes place. We explore the importance of multilevel processes in explaining cultural adaptation by describing how processes leading to cultural (mis)adaptation are linked through a complex nested hierarchy, where the lower levels combine into new units with new organizations, functions, and emergent properties or collective behaviours...

Human carbonic anhydrase XIV (CA XIV), a transmembrane protein, highly expressed in the central nervous system, is difficult to recombinantly express and purify in large scale for the measurements of inhibitor binding and drug design. CA XIV belongs to the family of twelve catalytically active CA isoforms in the human body. Disorders in the expression of CA XIV cause serious diseases and CA XIV has been described as a possible drug target for the treatment of epilepsy, some retinopathies, and skin tumors. In this study, the effect of different promoters, E...

A simple approach to fabricating hydroxyxapatite/titanium dioxide (HA/TiO2) coating on porous titanium (Ti) scaffolds was developed in the present study. Surface TiO2 layer was firstly formed on porous Ti scaffolds with multi-scale pores by acid-alkali (AA) treatment. The outer HA layer was then formed on the TiO2 layer by subsequent pulse electrochemical deposition (ED) technique. All the three main process parameters, i.e. deposition times, current density and mass transfer mode affected the properties of the HA coating notably...

Optically pure hinckdentine A was synthesized on a 300 mg scale via an asymmetric catalysis-based strategy. The key steps to the first asymmetric synthesis involved i) enantioselective dearomative cyclization of an achiral N-acyl indole that allowed for the efficient construction of the key polycyclic indoline intermediate with a crucial tetrasubstituted stereogenic carbon center, ii) Beckmann fragmentation-mediated ring expansion, iii) rearrangement-based introduction of an anilinic nitrogen atom, iv) regioselective tribromination, and v) final closure of the cyclic amidine moiety...

Concept mapping served as the starting point for the aim of capturing the comprehensive structure of the construct of 'health literacy.' Ideas about health literacy were generated by 99 experts and resulted in 105 statements that were subsequently organized by 27 experts in an unstructured card sorting. Multidimensional scaling was applied to the sorting data and a two and three-dimensional solution was computed. The three dimensional solution was used in subsequent cluster analysis and resulted in a concept map of nine "clusters": (1) self-regulation, (2) self-perception, (3) proactive approach to health, (4) basic literacy and numeracy skills, (5) information appraisal, (6) information search, (7) health care system knowledge and acting, (8) communication and cooperation, and (9) beneficial personality traits...

The visible-light-promoted diastereodivergent intramolecular oxyamination of alkenes and amination of unactivated C(Sp3)-H bonds is described to construct oxazolindinones, pyrrolidinones and imidazolidones via mild generation of primary amidyl radicals from functionalized hydroxylamines. A unique phenomenon on highly diastereoselective ring-opening of aziridines controlled by electron sacrifices was observed. High diastereoselective amino alcohols derivatives were obtained efficiently through this protocol in gram scales...

Anaerobic clostridial infection is the most severe form of paraproctitis. The incubation period is very short, from 3 to 6 hours, sometimes lasting for 1-2 days. Clostridial infection spreads rapidly and induces gas gangrene, causes destruction of cells and other intermediate substances, and impedes blood circulation. This paper presents a case study of an extremely severe form of anaerobic infection with spontaneous gas gangrene, cellulitis, fasciomyositic necrosis, severe intoxication and septic shock on the abdominal front and lateral surfaces...

Three different flow regimes were carried out in a pilot-scale horizontal subsurface flow constructed wetland-treating sulfate rich wastewater contaminated with monochlorobenzene (MCB) and perchloroethene (PCE). The three regimes were continuous flow, 7-day cycle discontinuous flow, and 2.5-day cycle discontinuous flow. The results show that intensifying the tidal regime (2.5-day cycle) significantly enhanced MCB removal before 2 m from the inlet and increasing PCE removal efficiency at 0.5 m. The PCE dechlorination process was promoted with tidal operation, especially under the 2...
