Hydrodynamical simulations for the common-envelope wind model for Type Ia supernovae [PDF]
The single-degenerate (SD) model is one of the leading models for the progenitors of Type Ia supernovae (SNe Ia). Recently, a new version of the SD model, the common-envelope wind (CEW) model, has been proposed, which, in principle, has the potential to resolve most of the difficulties encountered by previous SD models.

The nuclear envelope at a glance [PDF]
The cell nucleus is the ‘mothership’ that organizes, protects and regulates the genome. The inner and outer nuclear membranes (INM and ONM, respectively) of the nuclear envelope (NE) have over 60 distinct membrane proteins, whose roles and functional sophistication might rival the cell surface.

CDK2 regulates nuclear envelope protein dynamics and telomere attachment in mouse meiotic prophase [PDF]
In most organisms, telomeres attach to the nuclear envelope at the onset of meiosis to promote the crucial processes of pairing, recombination and synapsis during prophase I.

Diffusive Nuclear Burning in Neutron Star Envelopes [PDF]
We present a new mode of hydrogen burning on neutron stars (NSs) called diffusive nuclear burning (DNB). In DNB, the burning occurs in the exponentially suppressed tail of hydrogen that extends to the hotter regions of the envelope where protons are readily captured.

Nuclear envelope remnants: fluid membranes enriched in sterols and polyphosphoinositides.
BackgroundThe cytoplasm of eukaryotic cells is a highly dynamic compartment where membranes readily undergo fission and fusion to reorganize the cytoplasmic architecture, and to import, export and transport various cargos within the cell.

GAP activity, but not subcellular targeting, is required for Arabidopsis RanGAP cellular and developmental functions [PDF]
The Ran GTPase activating protein (RanGAP) is important to Ran signaling involved in nucleocytoplasmic transport, spindle organization, and postmitotic nuclear assembly.

Diseases of the Nuclear Envelope [PDF]
In the past decade, a wide range of fascinating monogenic diseases have been linked to mutations in the LMNA gene, which encodes the A-type nuclear lamins, intermediate filament proteins of the nuclear envelope. These diseases include dilated cardiomyopathy with variable muscular dystrophy, Dunnigan-type familial partial lipodystrophy, a Charcot-Marie ...

Remodeling of the Nuclear Envelope and Lamina during Bovine Preimplantation Development and Its Functional Implications. [PDF]
The present study demonstrates a major remodeling of the nuclear envelope and its underlying lamina during bovine preimplantation development. Up to the onset of major embryonic genome activation (MGA) at the 8-cell stage nuclei showed a non-uniform ...

Deformation of the nucleus by TGFβ1 via the remodeling of nuclear envelope and histone isoforms
The cause of nuclear shape abnormalities which are often seen in pre-neoplastic and malignant tissues is not clear. In this study we report that deformation of the nucleus can be induced by TGFβ1 stimulation in several cell lines including Huh7.

Signal Transduction across the Nuclear Envelope: Role of the LINC Complex in Bidirectional Signaling
The primary functions of the nuclear envelope are to isolate the nucleoplasm and its contents from the cytoplasm as well as maintain the spatial and structural integrity of the nucleus.
