Ultrasound-mediated gene transfection in vitro: effect of ultrasonic parameters on efficiency and cell viability.

Ultrasound (US)-mediated gene transfection in the presence of microbubbles is a recently developed and promising non-viral gene delivery method. Optimising the parameters used in ultrasonic transfection is urgently required in order to realise higher transfection efficiencies in clinical settings. This study examined the effect of ultrasound exposure parameters on plasmid DNA transfection in mouse embryonic fibroblast cell lines using perfluorobutane bubbles.

A case of congenital dyserythropoietic anemia type 1 in a Japanese adult with a CDAN1 gene mutation and an inappropriately low serum hepcidin-25 level.

We describe the first case of genetically diagnosed congenital dyserythropoietic anemia (CDA) type 1 in a Japanese man. The patient had hemolytic anemia since he was a child, and he developed diabetes, hypogonadism, and liver dysfunction in his thirties, presumably from systemic iron overload. When he was 48 years old a diagnosis was finally made by genetic analysis that revealed a homozygous mutation of CDAN1 gene (Pro1129Leu).

The role of interleukin-6 in a patient with polyclonal hairy B-cell lymphoproliferative disorder: a case report.

An 80-year-old female patient showed persistent lymphocytosis morphologically resembling the Japanese variant of hairy cell leukemia (HCL). However, flow cytometric analysis determined that these lymphocytes were of polyclonal B-cell origin, showing CD5-, CD10(-), CD11c(+), CD19(+), CD20(+), CD23(-), CD103(-), FMC7(-), HLA-DR(+) and surface membrane immunoglobulin (smIg) G(+) phenotype. The female patient also showed polyclonal hypergammaglobulinemia with bone marrow plasmacytosis.

[Improvement of thrombocytopenia with normalization of thyroid function in a patient with Graves disease].

A 39-year-old man was admitted to our hospital because of hyperthyroidism complicated with fever, atrial fibrillation with rapid ventricular response and congestive heart failure. Laboratory data revealed pancytopenia with a white blood cell count of 3360/microl, Hb 9.6 g/dl, and a platelet count of 88000/ul.

Cytotoxic T-cell non-Hodgkin's lymphoma of the thyroid gland.

An 86-year-old female was diagnosed with peripheral T-cell lymphoma, unspecified, which affected only her thyroid gland. Lymphoma cells were TIA-1(+), suggesting cytotoxic T-cell origin. She had not suffered from autoimmune thyroiditis and showed normal thyroid function.

Quinine-resistant severe falciparum malaria effectively treated with atovaquone and proguanil hydrochloride combination therapy.

A 22-year-old Japanese man noticed pyrexia and diarrhea after travel to Guinea. Notable physical findings included hepatosplenomegaly. Treatment with oral quinine and minocycline was started after definitive diagnosis of falciparum malaria by blood smear.

Electro-spinning and electro-blowing of hyaluronic acid.

In this study, hyaluronic acid (HA) was electro-spun and electro-blown to prepare nonwoven nanofibrous membranes. Critical parameters for processing and corresponding effects on the membrane morphology were investigated using the methods of rheology and scanning electron microscopy (SEM). During electro-spinning, the optimal HA concentration window for nanofibrous formation was determined within a narrow range of 1.

Asymmetrical-flow field-flow fractionation with on-line multiangle light scattering detection. 1. Application to wormlike chain analysis of weakly stiff polymer chains.

Four samples of hyaluronan in the sodium form, ranging in weight-average molecular weight, M(w), from 6.67 x 10(5) to 4.23 x 10(6) were investigated by asymmetrical-flow field-flow fractionation coupled to multiangle light scattering (FlFFF-MALS) in 0.

Infusion of a high number of CD34+ cells provides a rapid hematopoietic recovery and cost savings in autologous peripheral blood stem cell transplantation.

Background: The objectives of this study were to evaluate the effect of the number of infused CD34+ cells on hematopoietic recovery and on the cost in autologous peripheral blood stem cell transplantation (PBSCT).

Methods: Sixty-nine patients who received autologous PBSCT (ABSCT) were divided into three groups defined by the number of infused CD34+ cells. The number of days until 0.
