Stem cells are becoming increasingly more important in the field of regenerative medicine. Adult mesenchymal stem cells (MSCs) are harvested predominantly from bone marrow or adipose tissue, are already being used in the clinical setting and have a low potential for side effects. In orthopedics, experience has been gained in the treatment of bone defects, non-unions, cartilage defects, osteoarthritis and tendon pathologies. The current data are derived from case studies and randomized controlled trials are missing; therefore, there are many open questions concerning the optimal cell source, number of cells, administration technique (e...

Focal cartilage lesions are a cause of long-term disability and morbidity. After cartilage repair, it is crucial to evaluate long-term progression or failure in a reproducible, standardized manner. This article provides an overview of the different cartilage repair procedures and important characteristics to look for in cartilage repair imaging. Specifics and pitfalls are pointed out alongside general aspects. After successful cartilage repair, a complete, but not hypertrophic filling of the defect is the primary criterion of treatment success...

As the formation of pyridoxal phosphate, the active cofactor of vitamin B6, is dependent on riboflavin 5-phosphate, we propose a fast and simple ultra-high performance liquid chromatography method for the simultaneous determination of the native B6 vitamers pyridoxal, pyridoxine, pyridoxamine, their mono phosphorus esters and 4-pyridoxic acid as well as vitamin B2 as riboflavin and its phosphorus ester riboflavin 5-phosphate in milk. Separation was achieved under 6.0min by reversed-phase and pH gradient elution...

Primary intravascular synovial sarcoma is a rare malignancy with only a few cases documented in the literature. On presentation, this tumour usually resembles a deep venous thrombosis (dvt) or pulmonary embolism (pe). Here, we report the case of a 20-year-old woman complaining of shortness of breath who had a history of dvt 6 weeks before presentation at our institution. Vascular ultrasound detected a suspicious mass in the right groin, which was identified as a monophasic synovial sarcoma by surgical biopsy...

A new set-up for improved monitoring of atmospheric corrosion processes in situ and in real-time is presented. To characterize chemical structures of thin films on metal surfaces surface sensitive analytical techniques are required. One possible technique is Infrared Reflection Absorption Spectroscopy (IRRAS) which has become an established method to investigate surface corrosion films of thicknesses less than 200 nm. However, there are limitations related to the sensitivity of these measurements, in case of investigating ultrathin films or absorption bands of interest, surface species are superimposed by atmospheric background absorption, which changes during in situ measurements in ambient atmospheres...

BACKGROUND: Understanding the clinical pharmacology of the antifibrinolytic epsilon-aminocaproic acid (EACA) is necessary for rational drug administration in children. The aim of this study is to determine the pharmacokinetics (PKs) of EACA in infants aged 6-24 months undergoing craniofacial reconstruction surgery. METHODS: Cohorts of six infants were enrolled sequentially to one of the three escalating loading dose-continuous i.v. infusion (CIVI) regimens: 25 mg kg(-1), 10 mg kg(-1) h(-1); 50 mg kg(-1), 20 mg kg(-1) h(-1); 100 mg kg(-1), 40 mg kg(-1) h(-1)...

Plants contain variable chemical compositions which play a role in direct defense against phytophagous insects. Glucosinolates (GSs) are the predominant secondary metabolites and defense compounds in brassicaceous species. As a consequence of co-evolution between adapted crucifer-feeding specialists and their associated host-plants, specific plant-insect interactions have developed in a divergent manner from non-adapted generalists. Therefore, generalist and specialist insects may provoke different insect-inducible plant responses...

Increased feed costs affect the livelihoods of dairy sheep farmers in the Middle East. Farmers endure high risks with large fluctuations in the price of grain used as animal feed, which is further affected by drought and declining range productivity. Using agricultural by-products and treated straw or vetch grazing for supplementing sheep diets would provide resource-poor dairy farmers with increased options to reduce feed costs, but the effects of such feeds on the quality of yogurt (the main product) need to be better understood...

High feed costs are major obstacles for resource-poor dairy sheep farmers in West Asia, along with large fluctuation in grain and straw prices. Farmers need low-cost diets using locally available feeds that can provide sufficient milk of good quality. Two experimental trials were conducted on Awassi milking ewes to evaluate nonconventional and balanced low-cost diets against the traditional unbalanced diet used by farmers (control) on the total yields (milk, fat, protein, and total solids) and milk composition (fat, protein, total solids, and lactose), an important indicator of milk quality...

We review the current knowledge on alterations of the major basement membrane (BM) components and their cellular integrin receptors in benign and malignant tumors of epithelial and mesenchymal origin. While benign tumors usually exhibit a continous BM, recent analyses provide evidence that invasive growth of carcinomas coincides with (a) a loss in a proper BM, (b) changes in the type of integrin receptor expression and (c) the retained ability of certain tumor cells to synthesize matrix components. This latter aspect has been regarded as a potentially beneficial 'host' mechanism against invasive growth...

BACKGROUND: An increasing number of modern imaging procedures are being applied for the diagnosis of appendicitis. We compared one hundred consecutive appendectomies of the years 1988, 1998 and 2008 concerning reliability of preoperative diagnosis and resulting costs. METHODS: We analysed the first one hundred consecutive patients undergoing appendectomy during the years 1988, 1998 and 2008, 59 % were female and 41 % male. The average age was 26 years, the average BMI 21...

BACKGROUND AND OBJECTIVES: A high concentration of large size polymers in intravenous immunoglobulin preparations was always correlated with high anticomplementary activity (ACA). In former days, high ACA was also linked to adverse reactions in patients. The goal of this study was to scrutinize critical parameters of the ACA assay and the influence of different polymer variants of IgG on the complement consumption. MATERIALS AND METHODS: Critical reagents as the complement and the preparation of erythrocytes were investigated...

The knowledge available regarding the influence of ultraviolet (UV) light on the atmospheric corrosion of materials is very rudimentary. Therefore, a new experimental setup consisting of a cell for studying in situ reactions occurring at the metal/atmosphere interface by simultaneously applying infrared reflection absorption spectroscopy (IRRAS) and quartz crystal microbalance (QCM) measurements was designed and built. The cell presented consists of an acrylic glass body with a UV-light-transparent window mounted in such a way that the sample can be irradiated and weathered under controlled atmospheric conditions under a grazing angle of incidence of the IR beam...

Silver-coated quartz crystal microbalance (QCM) disks were treated under different environmental conditions (including changes in parameters such as relative humidity (%RH) and SO(2)/H(2)S content) in atmospheres of synthetic air and pure N(2) for 24 h in a weathering chamber. The corroded surfaces were subjected to depth profiling by a time of flight (TOF) secondary ion mass spectrometry (SIMS) instrument, equipped with a Bi(+) analysis gun and Cs(+) sputter gun. The evaluation of the in-depth distribution of several elements and species provides evidence for the formation of a corrosion layer containing Ag(2)SO(3), even in the absence of oxidizing agents, such as H(2)O(2) or NO(2)...

Glucosinolates of broccoli and cauliflower florets were assessed to determine the effect of modified-atmosphere packaging on postharvest glucosinolate dynamics in mixed florets of Brassica vegetables. Mixed-packaged broccoli and cauliflower florets stored in food trays sealed with 2 different microperforated biaxial-oriented polypropylene films for up to 7 d at 8 degrees C were analyzed. Both applied modified atmospheres (1% O(2)+ 21% CO(2); 8% O(2)+ 14% CO(2)) maintained aliphatic glucosinolates in cauliflower florets, whereas in broccoli florets, the aliphatic glucosinolate concentration decreased slightly in each modified atmosphere...

Protection against contact allergy begins with the collection of reliable data about the sensitizing potential of chemicals. Today, the local lymph node assay (LLNA) in mice is widely used to identify sensitizing substances. For several reasons, an in vitro assay could be preferable to animal experiments. We propose an in vitro test for the detection of a sensitizing potential of a chemical composed of a single layer of human nondifferentiating keratinocytes and of allogenic floating monocytes which are cocultured in serum-free medium in the presence of a cytokine cocktail...
