Innate inflammatory responses are crucial for induction and regulation of T cell and antibody responses. Mast cell (MC)-deficient mutant mice showed impaired adaptive immunity, suggesting that MCs provide essential adjuvant activities, and pharmacological MC activation was proposed as a new adjuvant principle. However, the mutations result in complex alterations of the immune system in addition to MC deficiency.

Fourteen dogs were fed a control diet or a diet supplemented with 1% beta-glucan during 71 days. Serum concentrations of glucose, total cholesterol and lipoprotein fractions, as well as plasma concentrations of peptide YY and ghrelin, were determined.

Tissue microarrays (TMAs) are commonly used in biomarker research. To enhance the efficacy of TMAs and to avoid floating or folding of tissue cores, various improvements such as the application of carriers and melting techniques have been proposed. Compared with classical TMAs (cTMAs), carrier-based TMAs (cbTMAs) have been shown to have several advantages including sample handling and sectioning.

High-dose melphalan (HDM) and autologous blood stem cell transplantation (ABSCT) is an effective treatment for transplantation-eligible patients with systemic light chain (AL) amyloidosis. Whereas most centers use granulocyte colony-stimulating factor (G-CSF) alone for mobilization of peripheral blood stem cells (PBSC), the application of mobilization chemotherapy might offer specific advantages. We retrospectively analyzed 110 patients with AL amyloidosis who underwent PBSC collection.

It has high digestibility and high energy content and likely improves digestibility of the diet when present in greater amounts, suggesting that endogenous fat adversely affects the apparent digestibility of fat in low-fat diets. This study aimed to determine the endogenous fat loss (EFL) and true total tract digestibility (TTTD) of fat in dogs by using diets having different fat:carbohydrate ratios.

The aim of this study was to evaluate the influence of rituximab-containing chemotherapy on HCV load. Fifty-four patients with both HCV infection and NHL were identified between 2000 and 2016 at our institution.

In recent years, biosimilar agents have been approved for the same indications. The aim of this retrospective study was to compare the mobilization efficiency of the three G-CSF variants originator filgrastim, lenograstim, and the biosimilar Filgrastim Hexal in a homogeneous group of multiple myeloma (MM) patients in first-line therapy.

However, these results were obtained in young low risk patients and a reevaluation in an unselected patient cohort is warranted.
Methods: In this study, we analyzed 80 PMBCL patients treated with a CHOP-based regimen with and without rituximab.
Aims: Human papilloma virus (HPV) infection is a causative agent for approximately 5% of all new cancer cases in humans. The virus is detected in cervical, anal, vaginal, penile, vulvar and head and neck cancers and has prognostic implications. Thus, test systems are required to detect high-risk but also low-risk HPV subtypes with high specificity and sensitivity in a time-effective and cost-effective manner.

Methods: Peripheral blood stem cells (PBSCs) were mobilized with high dose cyclophosphamide (2 g/m daily on days 1 and 2) and G-CSF plus pre-emptive/rescue plerixafor in RMM patients (first to third relapse) treated within the ReLApsE trial of the German-Speaking Myeloma Multicenter Group (GMMG).
Results: Mobilization was initiated with high-dose cyclophosphamide (HD-CY) and G-CSF in 30 patients.
Background: High-dose (HD) chemotherapy with melphalan and autologous blood stem cell transplantation (ABSCT) for treatment of symptomatic multiple myeloma (MM) on an outpatient basis has been well established in the USA and Canada, whereas in Germany and Western Europe an inpatient setting is the current standard. We report on a German single-centre program to offer the procedure on an outpatient basis to selected patients.
Methods: Major requirements included: patients had to have family and/or other caregivers, had to be able to reach the hospital within 45 min and have an ECOG performance score of 0-1.
Peripheral blood stem cells (PBSCs) are widely used for autologous blood stem cell transplantation (ABSCT). These cells must be stored for months or even years, usually at temperatures ≤-140°C, until their use. Although several in vitro studies on CD34 viability and clonogenic assays of PBSCs after long-term storage have been reported, only a few publications have investigated the influence of long-term storage on in vivo hematopoietic reconstitution.

Cystic echinococcosis (CE) is a pandemic infectious disease caused by the tapeworm Echinococcus granulosus that forms cysts in different organs such as lungs and liver. Imaging examination and serological tests have some drawbacks such as low sensitivity. In this study, we used an up-to-date workflow of laser microdissection-based microproteomics and matrix-assisted laser desorption/ionization time-of-flight imaging mass spectrometry in order to depict the proteomic pattern of CE in the liver.

In advanced tumor stages, diagnosis is frequently made from metastatic tumor tissue. In some cases, the identification of the tumor of origin may be difficult by histology alone. In this setting, immunohistochemical and molecular biological methods are often required.

As a new generation of leukapheresis (LP) machines has been launched, measures of benchmarking and quality control need to be defined in order to ensure consistent collection performance.
Objectives: The goal of this project was to establish and evaluate a benchmarking system for autologous PBSC collection.
Systemic amyloid light chain (AL) amyloidosis is a life-threatening protein deposition disorder; however, effective therapy can dramatically improve the prognosis of AL patients. Therefore, accurate diagnosis of the underlying hematologic disease is important. Multi-parameter flow cytometry (MFC) is a reliable method to analyze lymphatic neoplasias and to detect even a small lymphatic clone.

These criteria include clinical and laboratory parameters.

A common adverse effect of this protocol is renal toxicity which may result in treatment discontinuation. Assuming that a lower single dose of cisplatin over several days would reduce renal toxicity, our institution has chosen to administer cisplatin in a dosage of 25 mg/m(2) per day as a 3-h infusion over 4 consecutive days.

At our center, a modified R-DHAP regimen with administration of 25 mg/m(2) cisplatin as a 3-hour infusion over 4 consecutive days, instead of a single infusion of 100 mg/m(2) over 24 hours, has been established. The aim of this study was to analyze the efficiency of this modified R-DHAP regimen plus G-CSF as a mobilization strategy.

The aim of this retrospective study was to assess the safety and efficacy of bone marrow (BM) harvesting of allogeneic donors in an outpatient setting. Data of 226 related and unrelated donors who underwent BM harvest under general anesthesia at our institution from 2002 to 2014 were analyzed. Sixteen patients were a priori planned for admission for social reasons and 210 patients underwent BM harvesting with the intention to perform this procedure on an outpatient basis.
