Attitudes to illness and the use of health services by economic immigrants in Slovenia.

Aim: To analyze the attitudes of immigrants from former Yugoslav republics to Slovenia toward illness, concerns about and perception of health status, and factors that influence their use of health services for the prevention and treatment of illness.

Methods: We used a qualitative approach, employing the ETHNIC (Explain, Treatment, Healers, Negotiation, Intervention, Collaboration) questionnaire. We analyzed data from interviews with 27 economic immigrants who consecutively came to a general practice office from May 15 to August 15, 2005.

Sixteen novel mutations identified in COL4A3, COL4A4, and COL4A5 genes in Slovenian families with Alport syndrome and benign familial hematuria.

Alport syndrome (ATS) and benign familial hematuria (BFH) are type IV collagen inherited disorders. Mutations in COL4A5 are generally believed to cause X-linked ATS, whereas mutations in COL4A3 and COL4A4 genes can be associated with the autosomal-recessive and -dominant type of ATS or BFH. In view of the wide spectrum of phenotypes, an exact diagnosis is sometimes difficult to achieve.

The importance of non-invasive genetic analysis in the initial diagnostics of Alport syndrome in young patients.

Alport syndrome is an important hereditary disorder characterized by nephritis and sometimes accompanied by impairment or loss of vision and hearing. The most common form of Alport syndrome is an X-linked dominant trait that has been associated with the gene COL4A5, one of the six types of IV collagen genes. More than 300 different mutations have been identified in the COL4A5 gene, and appear randomly along the whole gene.

G-protein coupled progesterone receptors in the plasma membrane of fungus Rhizopus nigricans.

We have demonstrated simultaneous existence of progesterone receptors and GTPase activity in the membranes prepared from the filamentous fungus Rhizopus nigricans. The results obtained with pertussis toxin treated fungal mycelium suggest that these receptors do not couple to Gi-Go-proteins and play a role in the induction of steroid hydroxylating enzyme system by steroid substrates in the fungus.

Characterization of plasma membrane fraction from filamentous fungus Rhizopus nigricans.

In the filamentous fungus Rhizopus nigricans a steroid hydroxylating multienzyme system is inducible by progesterone and by several other steroids. The biological signal carried by progesterone might be mediated by receptors, located either in the plasma membrane or inside the cell. To elucidate the first possibility, plasma membrane fraction was examined for the presence of progesterone receptors.
