Bisphosphonates and atherosclerosis: why?

2005

The increasing knowledge on bone calcification processes has revealed some similarities with vascular tissue, where calcifications of arteries and cardiac valves contribute to several cardiovascular problems, such as heart failure, systolic hypertension, and myocardial and peripheral ischemic disease. Bisphosphonates have been used extensively for over two decades for the treatment of diseases associated with excessive bone resorption, i.e., osteoporosis, osteolytic bone metastasis, hypercalcemia and Paget’s disease, by blocking osteoclastic function. Etidronate, pamidronate and clodronate has been shown to inhibit the development of experimental atherosclerosis, and proposed mechanisms fo…

Liver Function Test Abnormalities in Patients with Inflammatory Bowel Diseases: A Hospital-based Survey

2014

Background and Aims Inflammatory bowel diseases (IBD) are frequently associated with altered liver function tests (LFTs). The causal relationship between abnormal LFTs and IBD is unclear. The aim of our study was to evaluate the prevalence and etiology of LFTs abnormalities and their association with clinical variables in a cohort of IBD patients followed up in a single center. Materials and Methods A retrospective review was undertaken of all consecutive IBD in- and outpatients routinely followed up at a single referral center. Clinical and demographic parameters were recorded. Subjects were excluded if they had a previous diagnosis of chronic liver disease. LFT abnormality was defined as …

Methylene blue-aided cholangioscopy in patients with biliary strictures: feasibility and outcome analysis

2008

BACKGROUND AND STUDY AIMS: Chromoendoscopy using methylene blue is employed in the gastrointestinal tract to delineate neoplastic lesions. We tested the value of chromoendoscopy during choledochoscopy for characterization of local inflammation, neoplasias, and other alterations in patients with biliary strictures. METHODS: Patients with suspected biliary lesions were scheduled for endoscopic retrograde cholangiography with subsequent cholangioscopy. After initial inspection of the bile duct, 15 ml methylene blue (0.1 %) was administered via the working channel of the cholangioscope. Newly appearing circumscribed or unstained lesions were judged according to their macroscopic type and staini…

Die kombinierte operative und radiotherapeutische Behandlung (CORT) von Beckenwandrezidiven: Erfahrungsbericht nach 3 Jahren

1993

CORT has been developed to treat recurrent gynaecological malignancies infiltrating the pelvic wall unilaterally. The surgical part consists of: (i) staging laparotomy/lymphadenectomy, (ii) maximum tumour resection at the pelvic wall and exenteration of infiltrated central pelvic organs, (iii) implantation of guiding tubes on the residual tumour/tumour bed on the pelvic wall, (iv) pelvic wall plasty with muscle, musculocutaneous and omentum flaps, (v) operative reconstruction of bowel, bladder and perineo-vulvo-vaginal functions. Radiation is performed as interstitial high dose rate brachytherapy through the implanted tubes. Patients without prior pelvic irradiation receive in addition, who…

Ergebnisse und Komplikationen von 616 perkutanen transhepatischen Gallenwegsdrainagen

1989

During nine years, percutaneous transhepatic biliary drainage was carried out 616 times on 563 patients in the Department of Radiology, University of Mainz Medical School. 50.3% were pre-operative and 39% were palliative. More than 80% were necessitated by malignant lesions. Subsequent improvements in biochemical measurements were observed in 82.4% of patients. Complications of the procedure led to the death of five patients (0.8%) and required surgery in nine patients (1.5%). The following complications were observed: biliary peritonitis in 0.6%, sepsis in 1.9%, bleeding in 1.9% and fever higher than 38 degrees C in 16.2%.

SUBFRACTIONS AND SUBPOPULATIONS OF HDL: AN UPDATE

2014

High-density lipoproteins (HDL) are classified as atheroprotective because they are involved in transport of cholesterol to the liver, known as "reverse cholesterol transport (RCT)" exerting antioxidant and anti-inflammatory activities. There is also evidence for cytoprotective, vasodilatory, antithrombotic, and anti-infectious activities for these lipoproteins. HDLs are known by structural, metabolic and biologic heterogeneity. Thus, different methods are able to distinguish several subclasses of HDL. Different separation techniques appear to support different HDL fractions as being atheroprotective or related with lower cardiovascular (CV) risk. However, HDL particles are not always prote…

Rheological and metabolic leucocyte determinants in diabetes mellitus

1995

In diabetics of type I and 2 we examined, in resting white blood cells (WBC), the filtration parameters (Initial Relative Flow Rate - lRFR, Clogging Rate - CR) employing the St. George Filtrometer, the polymorphonuclear cells (PMN) membrane fluidity, the PMN cytosolic Ca2+ content and the PMN membrane cholesterol/phospholipid ratio (C/PL). From the obtained data, it is evident that, while the lRFR of unfractionated WBC distinguishes normals from diabetics of type 1 and 2, the fIltration parameters of the PMN and mononuclear cells (MN) do not show any significant difference. PMN membrane fluidity, PMN cytosolic Ca2+ content and PMN C/PL do not discriminate normals from diabetics of type 1 an…

Corrected whole blood biomarkers - the equation of Dill and Costill revisited.

2018

Abstract An exercise bout or a dehydration often causes a reduction in plasma volume, which should be acknowledged when considering the change in biomarkers before and after the plasma changing event. The classic equation from Dill and Costill (1974, J. Appl. Physiol., 37, 247–248) for plasma volume shift is usually utilized in such a case. Although this works well with plasma and serum biomarkers, we argue in this note that this traditional approach gives misleading results in the context of whole blood biomarkers, such as lactate, white cells, and thrombocytes. In this study, we demonstrate that to calculate the change in the total amount of circulating whole blood biomarker, one should u…

Combination of hormone replacement therapy and high physical activity is associated with differences in Achilles tendon size in monozygotic female tw…

2009

Estrogen concentration has been suggested to play a role in tendon abnormalities and injury. In physically active postmenopausal women, hormone replacement therapy (HRT) has been suggested to decrease tendon diameter. We hypothesized that HRT use and physical activity are associated with Achilles tendon size and tissue structure. The study applied cotwin analysis of fourteen 54- to 62-yr-old identical female twin pairs with current discordance for HRT use for an average of 7 yr. Achilles tendon thickness and cross-sectional areas were determined by ultrasonography, and tendon structural organization was analyzed from the images using linear discriminant analysis (LDA). Maximal voluntary and…

Crataegus laevigata decreases neutrophil elastase and has hypolipidemic effect: a randomized, double-blind, placebo-controlled trial.

2011

Crataegus laevigata is a medicinal plant most commonly used for the treatment of heart failure and psychosomatic disorders. Based on previous experimental findings, this double-blind placebo-controlled study was aimed at finding beneficial effects of C. laevigata on biomarkers of coronary heart disease (CHD). The study included 49 diabetic subjects with chronic CHD who were randomly assigned to the treatment for 6 months with either a micronized flower and leaf preparation of C. laevigata (400 mg three times a day) or a matching placebo. Blood cell count, lipid profile, C-reactive protein, neutrophil elastase (NE) and malondialdehyde were analyzed in plasma at baseline, at one month and six…
