The role of local non-tetragonal polar displacements in the temperature- and pressure-induced phase transitions in PbTiO-BiMeO ferroelectrics.

In situ high-pressure/high-temperature Raman-scattering analyses on PbTiO , 0.92PbTiO 0.08Bi(Zn Ti )O and 0.

Influence of pemphigoid gestationis on pregnancy outcome: A case report and review of the literature.

Pemphigoid gestationis is considered to be a rare pregnancy exclusive bullous disease, which modifies the course of the pregnancy, with difficulties in the management of the pruritus and skin lesions as well as a possible change in the neonatal outcome. Differential diagnosis of skin lesions and pruritus in pregnancy is challenging, and complementary investigations such as skin biopsy or laboratory tests are indispensable. The correct diagnosis and proper treatment could change the natural course of a pregnancy at risk and could improve maternal and fetal morbidity.

Granulomatous slack skin - seven years follow-up of a case with features of "parapsoriasis en plaques", muscle involvement, granulomatous vasculitis, and necrobiotic changes.

Granulomatous slack skin (GSS) represents an extremely rare variant of mycosis fungoides with only 70 cases reported in the literature to date. It is characterized clinically by the occurrence of bulky, pendulous skinfolds, usually located in flexural areas and histologically by an infiltrate composed of small neoplastic T-lymphocytes joined by granulomatous inflammation with scattered multinucleated giant cells containing nuclei arranged in a wreath-like fashion. Since its first description, very rare cases of GSS with muscle involvement, large vessels involvement, or necrobiotic changes have been reported.

Desmoplastic melanoma--challenges in the diagnosis and management of a rare cutaneous tumor.

Desmoplastic melanoma (DM) represents a distinctive rare variant of spindle cell melanoma with a predilection for chronically sun-exposed skin of the elderly. This neoplasm is notoriously difficult to diagnose, both clinically and histopathologically. Therefore, DM is deeply infiltrative at the time of presentation.

Completely regressed primary cutaneous melanoma - difficulties in diagnosis and classification.

Complete regression of primary cutaneous melanoma is a very rare phenomenon. Only 49 cases of well-documented completely regressed primary cutaneous melanoma have been reported to date. The clinical picture and histological findings may vary considerably.

Determination of the relative level of detection of a Qualitative microbiological measurement method with respect to a reference measurement method.

Performance of qualitative microbiological measurement methods where the results are either "O" (microorganism not detected) or "1" (microorganism detected) is described by their probability of detection (POD) function, i.e., the POD as a function of the level of contamination of the sample, expressed as CFU/g or CFU/mL, or by the level of detection (LODp), i.

A study assessing the feasibility and diagnostic accuracy of real-time teledermatopathology.

Dermatopathology represents the gold standard for the diagnosis of skin diseases and neoplasms that cannot be diagnosed on clinical grounds alone. The aim of this study was to test the feasibility and to assess the accuracy of an Internet-based real-time (live) teledermatopathology consultation. Twenty teaching cases and 10 randomly selected routine cases were presented to four expert dermatopathologists, first by real-time teledermatopathology and, subsequently, in a blinded fashion, using light microscopy.

Serum markers in skin melanoma--preliminary study.

Skin melanoma presents the strongest metastatic capacity and the highest mortality rate of all types of skin cancer, being one of the most aggressive forms of human cancer. Although melanoma represents only 4% of skin cancers, it accounts for 80% of skin cancer deaths. The aim of this study was the investigation of two specific serum markers for melanoma: S100B and melanoma inhibitory activity in relation to disease development.

Biomarkers of metastatic melanoma.

Melanoma, one of the most aggressive forms of human cancer, has undergone an alarming increase in incidence in recent years. Early detection is a prerequisite for proper diagnosis and therapy orientation. Soluble biomarkers are an important tool for early diagnosis.

Cell investigations simultaneously with exposure to 2.45 GHz microwaves.

The paper presents two microwave (MW) exposure systems (MWESs) that permit observations and measurements on cell cultures during their exposure to MW of 2.45 GHz: MWES-1 and MWES-2. MWES-1 is designed for the measurement of the cell membrane fluorescence anisotropies (MFA) simultaneously with MW exposure.

Combined microwave and electron beam exposure facilities for medical studies and applications.

The paper presents two radiation exposure facilities (REFs) which permit separate and simultaneous irradiation with microwaves (MW) of 2.45 GHz and electron beams (EB) of 6.23 MeV for malignant melanoma (MM) cell investigations, in vitro (MW+EB-REF-vitro) and in vivo (MW+EB-REF-vivo).
