Membrane fusion, one of the most fundamental processes in life, occurs when two separate lipid membranes merge into a single continuous bilayer. Fusion reactions share common features, but are catalyzed by diverse proteins. These proteins mediate the initial recognition of the membranes that are destined for fusion and pull the membranes close together

We discuss when and how the Verlinde dimensions of a rational conformal field theory can be expressed as correlation functions in a topological LG theory. It is seen that a necessary condition is that the RCFT fusion rules must exhibit an extra symmetry. We consider two particular perturbations of the Grassmannian superpotentials.

Selective cell fusion is a natural part of development. It is found in sexually reproducing organisms that require fertilization to propagate and in muscles, placenta, bones, lens of the eye and stem cells. Cell fusion is particularly important in the development of C. elegans: in addition to 300 sperm and oocytes that fuse during fertilization, 300 of

Fusion of biological membranes is governed by physical principles but it is unclear whether the transition states are primarily determined by lipid physics or by protein-lipid interactions. Recent advances in the field include the physical description of bilayer fusion, particularly new models beyond continuum models and the role of the SNARE proteins.

There are many advantages to writing functional programs in a compositional style, such as clarity and modularity. However, the intermediate data structures produced may mean that the resulting program is inefficient in terms of space. These may be removed using deforestation techniques, but whether the space performance is actually improved depends ...

Summary: Lisfranc injuries remain a frequently missed pathology and may present as an isolated injury or as a component of a polytrauma case. Weight-bearing films or advanced imaging such as CT may be imperative in identifying or further classifying the injury.

Radioscapholunate Fusions [PDF]
Radiocarpal fusions are performed for a variety of indications, most commonly for debilitating painful arthritis. The goal of a wrist fusion is to fuse the painful, diseased joints and to preserve motion through the healthy joints. Depending on the extent of the disease process, radiocarpal fusions may take the form of radiolunate, radioscapholunate ...

We report a case of an 11-year-old boy who presented with a painless left scrotal mass of one year's duration. Clinical examination and diagnostic modalities indicated a solid left testicular mass. Exploration was done and a complete splenogonadal fusion was found.

Subcellular compartmentalization, cell growth, hormone secretion and neurotransmission require rapid, targeted, and regulated membrane fusion. Fusion entails extensive lipid rearrangements by two apposed (docked) membrane vesicles, joining their membrane proteins and lipids and mixing their luminal contents without lysis.
