Article Synopsis
- The diagnosis of systemic amyloidosis typically involves detecting amyloid deposits in tissue samples, often taken from abdominal skin due to the non-invasive nature of the procedure.
- Various staining techniques, including Thioflavin T (ThT), Congo Red, and Direct Fast Scarlet (DFS), are used for visualization, but ThT can produce false-positive results when lipomembranous fat necrosis (LFN) is present.
- To avoid misdiagnosis, it's important to know that LFN can interfere with amyloid screening tests, hence skin samples should be taken from areas not affected by such changes and using multiple stains is advisable for more accurate results.
We have investigated the influence of multiple scattering on the magnetic small-angle neutron scattering (SANS) from a Nd-Fe-B nanocrystalline magnet. We performed sample-thickness- and neutron-wavelength-dependent SANS measurements, and observed the scattering vector dependence of the multiple magnetic scattering. It is revealed that significant multiple scattering exists in the magnetic scattering rather than the nuclear scattering of Nd-Fe-B nanocrystalline magnet.

In this study, structural analyses were performed on L1(0)-FePd/α-Fe NCMs with various hard/soft volume fractions, which were formed by annealing Pd/γ-Fe(2)O(3) heterostructured nanoparticles and pure Pd nanoparticles. The sample with a hard/soft volume ratio of 82/18 formed by annealing at 773 K had the largest maximum energy product (BH(max) = 10.

We report a case of linear scleroderma with this process. Histopathology of the lesion showed numerous solid and cystic epithelial structures with squamous metaplasia within typical sclerodermatous skin lesions.
View Article and Find Full Text PDFApoptosis is a physiological form of cell death that is responsible for the deletion of cells. Epidermal keratinocytes are supposed to be regulated by cell proliferation and cell death leading to structural homeostasis. Psoriatic skin shows marked thickening of the epidermis, suggesting the imbalance of the homeostasis, which might be related to abnormal apoptotic process.
