Intracellular membrane fusion requires SNARE proteins in a trans-complex, anchored to apposed membranes. Proteoliposome studies have suggested that SNAREs drive fusion by stressing the lipid bilayer via their transmembrane domains (TMDs), and that SNARE complexes require a TMD in each docked membrane to promote fusion. Yeast vacuole fusion is believed to require three Q-SNAREs from one vacuole ...

Various types of stem cells have been shown to have beneficial effects on cardiac function. It is still debated whether fusion of injected stem cells with local resident cardiomyocytes is one of the mechanisms. To better understand the role of fusion in stem cell-based myocardial regeneration, the present study was designed to investigate the fate of human adipose tissue-derived stem cells (hAS...

Splenogonadal fusion is a rare entity with approximately 150 reported cases until the year 2005. The entity is a rare congenital anomaly in which there is fusion of splenic and gonadal anlagen or mesonephric derivatives. Splenogonadal fusion has two continuous and discontinuous types. About ten cases have been reported to be associated with bilateral cryptorchidism in literature. Very few cases...

Traditional semantic models are disembodied from the human perception and action. In this work, we attempt to address this problem by grounding semantic representations of words to the acoustic and visual modalities. Specifically we estimate multimodal word representations via the fusion of auditory and visual modalities with the text modality. We employ middle and late fusion of representation...

Human parainfluenza viruses cause several serious respiratory diseases in children for which there is no effective prevention or therapy. Parainfluenza viruses initiate infection by binding to cell surface receptors and then, via coordinated action of the 2 viral surface glycoproteins, fuse directly with the cell membrane to release the viral replication machinery into the host cell's cytoplasm...

The Paramyxoviridae family of enveloped viruses enters cells through the concerted action of two viral glycoproteins. The receptor-binding protein, hemagglutinin-neuraminidase (HN), H, or G, binds its cellular receptor and activates the fusion protein, F, which, through an extensive refolding event, brings viral and cellular membranes together, mediating virus-cell fusion. However, the underlyi...

Analyses of the conformational dynamics of the numerous cellular ribonucleoprotein particles (RNP) significantly contribute to the understanding of their modes of action. Here, we tested whether ribonuclease fusion proteins incorporated into RNPs can be used as molecular probes to characterize the local RNA environment of these proteins. Fusion proteins of micrococcal nuclease (MNase) with ribo...
