Life, death and burial: multifaceted impact of autophagy.
Macroautophagy, often referred to as autophagy, designates the process by which portions of the cytoplasm, intracellular organelles and long-lived proteins are engulfed in double-membraned vacuoles (autophagosomes) and sent for lysosomal degradation. Basal levels of autophagy contribute to the maintenance of intracellular homoeostasis by ensuring the turnover of supernumerary, aged and/or damag...
متن کاملGreen Genes—Comparative Genomics of the Green Branch of Life
As more plant genome sequences become available, researchers are increasingly using comparative genomics to address some of the major questions in plant biology. Such questions include the evolution of photosynthesis and multicellularity, the developmental genetic changes responsible for alterations in body plan, and the origin of important plant innovations such as roots, leaves, and vascular ...

This paper aimed to determine the required competencies for training medical students to acquire lifelong learning. Methods: In this qualitative study, purposeful sampling method and open-ended semi-structured interview were employed for ...
متن کاملLong-distance life rafting
Ordering and disordering electrons When a liquid is cooled rapidly, it can form a glass, a state stuck between liquid and solid. Two groups looked in detail into analogous dynamics in electronic systems. Sato et al. and Sasaki et al. studied layered organic materials with a triangular in-plane lattice. These materials can assume a state in which their charge distribution has a regular pattern—a...
متن کاملBedforms and Mine Burial
The generation and migration of bedforms (eg, ripples, megaripples and sand bars) on sandy bottoms in the nearshore (0-8 m water depths) provides a mechanism for objects on the seafloor to become buried. As a bedform migrates past a mine, the mine will fall to the low point of the bedform trough before subsequently being buried by the passage of the following bedform crest. The statistics of mi...
