Hybrid Organic-Inorganic Perovskite Halide Materials for Photovoltaics towards Their Commercialization.

Hybrid organic-inorganic perovskite (HOIP) photovoltaics have emerged as a promising new technology for the next generation of photovoltaics since their first development 10 years ago, and show a high-power conversion efficiency (PCE) of about 29.3%. The power-conversion efficiency of these perovskite photovoltaics depends on the base materials used in their development, and methylammonium lead iodide is generally used as the main component.

Region-Specific Cell Membrane N-Glycome of Functional Mouse Brain Areas Revealed by nanoLC-MS Analysis.

N-glycosylation is a ubiquitous posttranslational modification that affects protein structure and function, including those of the central nervous system. N-glycans attached to cell membrane proteins play crucial roles in all aspects of biology, including embryogenesis, development, cell-cell recognition and adhesion, and cell signaling and communication. Although brain function and behavior are known to be regulated by the N-glycosylation state of numerous cell surface glycoproteins, our current understanding of brain glycosylation is limited, and glycan variations associated with functional brain regions remain largely unknown.

Asystole in Orthognathic Surgery: A Case Report.

A previously healthy 26-year-old man presented for elective Le Fort I osteotomy, bilateral mandibular osteotomy, and genioplasty. During the intraoperative course, the patient developed sudden bradycardia and asystole on placement of a bite block. Asystole is an extremely rare consequence of the trigeminocardiac reflex, and awareness of this potentially life-threatening complication is pivotal in its management.
