Efficacy and Tolerability of High- versus Low-dose Lenalidomide Maintenance Therapy of Multiple Myeloma after Autologous Blood Stem Cell Transplantation.

Purpose: For multiple myeloma, high-dose chemotherapy and autologous blood stem-cell transplantation (ASCT) followed by lenalidomide maintenance (LenMT) at 10-15 mg/day is considered standard of care. However, dose reductions due to side effects are common and median LenMT doses achieved over time may remain lower. Dose response during LenMT has never been investigated.

New multi protein patterns differentiate liver fibrosis stages and hepatocellular carcinoma in chronic hepatitis C serum samples.

Aim: To identify a multi serum protein pattern as well as single protein markers using surface-enhanced laser desorption/ionisation time-of-flight mass spectrometry (SELDI-TOF-MS) for detection and differentiation of liver fibrosis (F1-F2), liver cirrhosis (F4) and hepatocellular carcinoma (HCC) in patients with chronic hepatitis C virus (HCV).

Methods: Serum samples of 39 patients with F1/F2 fibrosis, 44 patients with F4 fibrosis, 34 patients with HCC were applied to CM10 arrays and analyzed using the SELDI-TOF ProteinChip System (PBS-IIc; Ciphergen Biosystems) after anion-exchange fractionation. All patients had chronic hepatitis C and histologically confirmed fibrosis stage/HCC.

[Iron as comorbid factor in chronic hepatitis C].

Hepatitis C virus infection is often associated with an elevation of iron parameters. Free liver iron causes liver damage and liver fibrosis preferentially through induction of reactive oxygen species. With an allele frequency of 5-10% for the C282Y mutation and 6-30% for the H63D mutation, there is a frequent coincidence of hemochromatosis (HFE) mutations and chronic hepatitis C.

Ds-like restless deletion derivatives occur in Tolypocladium inflatum and two foreign hosts, Neurospora crassa and Penicillium chrysogenum.

Single copies of the transposon Restless from Tolypocladium inflatum were introduced into Neurospora crassa and Penicillium chrysogenum. Excision of Restless from its donor site was investigated in N. crassa and in P.
