original article   mental fatigue (mf) is considered as a contributor factor in incident, even catastrophic one. electroencephalography measurement has been the most acceptable method to assess mf by neurologists. however, this method could be hardly feasible in real work setting. flicker fusion device, by contrast, is more usable at work setting. the purpose of this study was to compare the cr...

background: controlling the hemodynamic situation of patients who have spinal operation is of prime importance, and maintaining the heart rate and blood pressure in normal or low- normal levels in these patients can reduce their bleeding loss. one of the commonly used drugs for this purpose is remifentanil. another sedative-hypnotic-analgesic drug, with acceptable effects is dexmedetomidine. th...

Extending and improving the concepts: woven frame and fusion frames, we introduce the notion of woven fusion frames in Hilbert spaces. We clarify our extension and generalization by some examples of woven frames and woven fusion frames. Also, we present some properties of woven fusion frames, especially we show that for given two woven frames of sequences, one can build woven fusion frames and ...

We establish a set of general results to study how the Galois action on modular tensor categories interacts with fusion subcategories. This includes characterization subcategories which are closed under action, and classification factor as product pointed transitive in terms pseudoinvertible objects. As an application, we classify two orbits simple objects nontrivial grading group.

Sexual reproduction is almost universal in eukaryotic life and involves the fusion of male and female haploid gametes into a diploid cell. The sperm-restricted single-pass transmembrane protein HAP2-GCS1 has been postulated to function in membrane merger. Its presence in the major eukaryotic taxa-animals, plants, and protists (including important human pathogens like Plasmodium)-suggests that m...

The two universally required components of the intracellular membrane fusion machinery, SNARE and SM (Sec1/Munc18-like) proteins, play complementary roles in fusion. Vesicular and target membrane-localized SNARE proteins zipper up into an alpha-helical bundle that pulls the two membranes tightly together to exert the force required for fusion. SM proteins, shaped like clasps, bind to trans-SNAR...

Cadherins are transmembrane glycoproteins that mediate Ca(2+)-dependent homophilic cell-cell adhesion and play crucial role during skeletal myogenesis. M-cadherin is required for myoblast fusion into myotubes, but its mechanisms of action remain unknown. The goal of this study was to cast some light on the nature of the M-cadherin-mediated signals involved in myoblast fusion into myotubes. We f...

Fast neuronal signalling relies on highly regulated vesicle fusion and recycling at specialized presynaptic terminals. Recently, examples of non-classical neurotransmission have also been reported, where fusion of vesicles can occur at sites remote from conventional synapses. This has potentially broad biological implications, but the underlying mechanisms are not well established. Here we show...
