Development of a bioactive glass-polymer composite for wound healing applications.

This study reports the production and characterization of a composite material for wound healing applications. A bioactive glass obtained by sol-gel process and doped with two different metal ions was investigated. Silver (Ag) and cobalt (Co) were chosen due to their antibacterial and angiogenic properties, respectively, very beneficial in the wound healing process.

Sonographic prenatal diagnosis of intracranial fetus in fetu.

A case of sonographic prenatal diagnosis of a complex intracranial mass, with features of a fetus in fetu at 17 weeks' gestation, is reported. This diagnosis is reserved for a highly organized tumor containing a vertebral column and recognizable fetal parts and should be differentiated from a teratoma.

[Receptor status (ER and PgR) determined with histochemical and biochemical methods in breast carcinoma].

Recently, a method similar to ER.ICA has been proposed for the progesterone receptor (PgR) using two monoclonal antibodies, JZB39 and KD68, specific for human PgR and characterized by a molecular weight of 95 and 120 Kd, respectively. A series of 73 breast cancer patients was studied with regards to ER and PgR using both immunocytochemical (ICA) and biochemical (DCC) assays.

[Receptor assessment of primary breast carcinoma and synchronous metastatic lymph nodes: histochemical study].

Several AA, utilizing the biochemical method (DCC) showed the presence or absence of hormonal receptor in either synchronous or metachronous metastatic nodes (N) can reproduce the receptor assessment (AR) of the primary breast tumor (T). We evaluated the AR in T and in synchronous N, by using two morphological methods, immunocytochemical and histofluorescent, to detect the nuclear Estrogen Receptor (ER1) and cytoplasmic sites of the II type (ER2 and PgR2). We studied 50 patients who underwent radical mastectomy for breast cancer N+.
