Objectives To report a case in where a mural endocarditis caused by Candida parapsilosis was successfully treated with the combination of 2 antifungal agents, caspofungin and voriconazole, in an extremely premature infant. Description A female infant born at 30.7 weeks with weight 925 g. The infant had a pneumothorax and respiratory distress syndrome, requiring prolonged mechanical ventilation, 1 venous umbilical and 3 central catheters, and broad-spectrum antibiotics. At 51 days of life, an echocardiogram showed an image compatible with fungal vegetation on the junction of the superior vena cava to the right atrium. Blood cultures grew Candida parapsilosis in various sequential samples, despite treatment with fluconazole and amphotericin-B and in vitro sensitivity to these drugs. A treatment of combined voriconazole and caspofungin was initiated resulting in clinical improvement and no need for surgical removal of vegetation. Comments Combined therapy with newer antifungal agents can be life-saving in premature infants with Candida parapsilosis complicated sepsis.

Metaphase chromosomes from human and mouse cells in vitro are isolated by micrurgy, fixed, and placed on grids for electron microscopy. Interpretations of electron micrographs by current methods indicate the following structural features.Chromosomal spindle fibrils about 200Å thick form fascicles about 600Å thick, wrapped by dense spiraling fibrils (DSF) less than 100Å thick as they near the kinomere. Such a fascicle joins the future daughter kinomere of each metaphase chromatid with those of adjacent non-homologous chromatids to either side. Thus, four fascicles (SF, 1-4) attach to each metaphase kinomere (K). It is thought that fascicles extend from the kinomere poleward, fray out to let chromosomal fibrils act as traction fibrils against polar fibrils, then regroup to join the adjacent kinomere.

SummaryDespite the use of potent anticoagulants such as r-hirudin and argatroban, the morbidity and mortality in heparin-induced thrombocytopenia (HIT) patients remains unacceptable. Data from our in vitro investigations show that thrombin inhibitors do not block platelet activation induced by heparin antibodies and heparin but that GPIIb/IIIa receptor inhibitors do block this process. We have treated four HIT positive patients with a combined therapy of thrombin inhibitor and GPIIb/IIIa receptor inhibitor when treatment with thrombin inhibitor alone failed to alleviate acute thrombosis. Combination therapies included r-hirudin (Refludan®) with tirofiban (Aggrastat®) and argatroban (Novastan®) with abciximab (ReoPro®). A reduced dose of the thrombin inhibitor was used with the standard dose of the anti-platelet drug. In all cases, there was no overt bleeding which required intervention, and all patients exhibited clinical improvement or full recovery. These case studies suggest that treatment of active thrombosis in HIT patients with adjunct GPIIb/IIIa receptor inhibitor therapy may be more effective than thrombin inhibitor treatment alone.

Interfering Rna

A genetikában új korszak kezdődött 17 éve, amikor a petúniában felfedezték a koszuppressziót. Később a koszuppressziót azonosították a növényekben és alacsonyabb rendű eukariótákban megfigyelt RNS-interferenciával (RNSi). Bár a növényekben ez ősi vírusellenes gazdaszervezeti védekezőmechanizmus, emlősökben az RNSi élettani szerepe még nincs teljesen tisztázva. Az RNSi-t rövid kettős szálú interferáló RNS-ek (short interfering RNA, siRNS) irányítják. A jelen cikkben összefoglaljuk az RNSi történetét és mechanizmusát, az siRNS-ek szerkezete és hatékonysága közötti összefüggéseket, a célsejtbe való bejuttatás virális és nem virális módjait. Az siRNS-ek klinikai alkalmazásának legfontosabb akadálya az in vivo alkalmazás. Bár a hidrodinamikus kezelés állatokban hatékony, embereknél nem alkalmazható. Lehetőséget jelent viszont a szervspecifikus katéterezés. A szintetizált siRNS-ek ismert mellékhatásait szintén tárgyaljuk. Bár a génterápia ezen új területén számos problémával kell szembenézni, a sikeres in vitro és in vivo kísérletek reményt jelentenek emberi betegségek siRNS-sel történő kezelésére.

Sporotrichosis is a serious public health problem in Brazil that affects human patients and domestic animals, mainly cats. Thus, the search for new antifungal agents is required also due to the emergence and to the lack of effective drugs available in the therapeutic arsenal. The aim of this study was to evaluate the in vitro antifungal profile of two synthetic series of coumarin derivatives against Sporothrix schenckii and Sporothrix brasiliensis. The three-components synthetic routes used for the preparation of coumarin derivatives have proved to be quite efficient and compounds 16 and 17 have been prepared in good yields. The inhibitory activity of nineteen synthetic coumarins derivatives 16a-i and 17a-j were evaluated against Sporothrix spp. yeasts and the most potent compounds were 16b and 17i. However, according to concentrations able to inhibit (minimum inhibitory concentrations) and kill (minimum fungicidal concentrations) the cells, 17i was more effective than 16b against Sporothrix spp. Thus, 17i exhibited good antifungal activity against S. brasiliensis and S. schenckii, suggesting that it is an important scaffold for the development of novel antifungal agents.

Aims: The aim of this review is to survey the recent progress made in developing the nanoparticles as antifungal agents especially the nano-based formulations being exploited for the management of Candida infections. Discussion: In the last few decades, there has been many-fold increase in fungal infections including candidiasis due to the increased number of immunocompromised patients worldwide. The efficacy of available antifungal drugs is limited due to its associated toxicity and drug resistance in clinical strains. The recent advancements in nanobiotechnology have opened a new hope for the development of novel formulations with enhanced therapeutic efficacy, improved drug delivery and low toxicity. Conclusion: Metal nanoparticles have shown to possess promising in vitro antifungal activities and could be effectively used for enhanced and targeted delivery of conventionally used drugs. The synergistic interaction between nanoparticles and various antifungal agents have also been reported with enhanced antifungal activity.
