Chiral Phase Change Nanomaterials

Advanced Functional Materials, EarlyView.
This work demonstrates reversible, non‐volatile phase transitions in chiral Ge2${\rm Ge}_2$Sb2${\rm Sb}_2$Te5${\rm Te}_5$ (GST) nanohelices for high‐speed optical modulation of chirality and dynamic control of the state of polarization (SOP). The chiral nanostructures are fabricated using a highly directional, wafer‐scale physical vapor deposition ...

Pull‐and‐Push Nanotherapeutic Hydrogels: Scavenging Inflammatory Triggers While Driving Tissue Regeneration in Burn Wounds

Advanced Functional Materials, EarlyView.
A nanounit‐assembled hydrogel employing a “pull‐and‐push” strategy simultaneously scavenges pro‐inflammatory cell‐free DNA (cfDNA) and delivers regenerative therapeutics in response to burn‐induced hyperthermia. By repolarizing macrophages and promoting angiogenesis, this multifunctional platform accelerates burn wound healing, offering a blueprint for

Macrophage and epithelioid cell nuclear morphology in leprosy

Pathology Research and Practice, 1992
The spectrum of disease in leprosy is characterised by the presence of macrophages in lepromatous lesions and epithelioid cells in tuberculoid granulomas. Since changes in nuclear shape occur during macrophage activation, we have measured nuclear morphology by planimetry in biopsies across the leprosy spectrum.

Freeze-fracture morphology of nuclear pockets

Virchows Archiv B Cell Pathology Including Molecular Pathology, 1991
Nuclear pockets (NP) are found in numerous human tumours and in certain non-neoplastic cells. This study concerns the structure of NP in cells from two malignant rhabdoid tumours, one embryonal rhabdomyosarcoma, two centroblastic/centrocytic lymphomas, one centrocytic lymphoma and one Ki-1 lymphoma, as well as in normal neutrophils.

Nuclear Morphology of Human Spermatozoa

Nature, 1960
THIS communication concerns observations on dried, unstained smears of human spermatozoa in phase contrast. These were made in an attempt to gain more insight into the basis for the known differential in conception and birth sex ratios.

Nuclear morphology during the S phase

Microscopy Research and Technique, 1998
In order to evaluate at the ultrastructural level the chromatin arrangement during the S phase of the cell cycle, the detection of Bromodeoxyuridine (BrdU) by immunogold has been performed in synchronized 3T3 fibroblasts, regenerating liver, and Friend Leukemia Cells (FLC).

The composition and morphology of yeast nuclear scaffolds

Journal of Cell Science, 1990
ABSTRACT The yeast nuclear scaffold has been shown to bind with high affinity to genomic sequences that permit autonomous DNA replication of plasmids (ARS elements). We describe here conditions for the isolation of a histone-free nuclear substructure, the nuclear scaffold, from Saccharomyces cerevisiae. We examine the protein composition

p300 Modulates Nuclear Morphology in Prostate Cancer

Cancer Research, 2005
Abstract Alterations in nuclear structure distinguish cancer cells from noncancer cells. These nuclear alterations can be translated into quantifiable features by digital image analysis in a process known as quantitative nuclear morphometry.
