Nature is a source of many plant-based molecules used as pro- or drugs. Eleutherococcus species are native to Asia and the North Russia, and are traditionally used to treat various diseases. In turn, neither secondary metabolites of the species cultivated in the West Europe nor the bioactivity is known. No differences in the phenols and flavonoids content in the inflorescences were found. The richest in polyphenols was E. giraldii (5.18 mg/g), while in flavonoids it was E. gracilistylus (1.80 mg/g). Using LC-ESI-MS/MS, protocatechuic and trans-caffeic acids have been identified as the most abundant compounds in E...

Aberrant pH is characteristic of many pathologies such as ischemia, inflammation or cancer. Therefore, a non-invasive and spatially resolved pH determination is valuable for disease diagnosis, characterization of response to treatment and the design of pH-sensitive drug delivery systems. We recently introduced hyperpolarized zymonic acid (ZA) as a novel MRI probe of extracellular pH utilizing dissolution dynamic polarization (DNP) for a more than 10,000-fold NMR signal enhancement. Here we present a strategy to enhance the sensitivity of this approach by deuteration of ZA (ZAd)...

Bisphosphonates are antibone resorptive drugs that are used to prevent bone tissue resorption in several skeletal diseases. The aim of this study was to examine the effects of systemic and local applications of zoledronic acid (ZA) on newly regenerated bone in a model of experimental distraction osteogenesis (DO). To do this mandibular DO was applied to 30 adult female Sprague Dawley rats, which were randomly divided into 3 groups: control, DO only, systemic zoledronic acid (SZA), and local zoledronic acid (LZA)...

The early detection and thus treatment of breast cancer bone metastasis remain a big challenge clinically. As the most abundant cells within bone tissue, osteocytes have been found to manipulate the activity of early cancer bone metastasis by its crosstalk with cancer cells and osteoclasts. However, conventional bone-targeting nanomedicine has limited bone-lesion specificity and ignores the vital role of osteocytes during breast cancer bone metastasis. Also, it lacks detailed insight into the therapeutic mechanisms, which hinders the following translational practice...

Upland cotton (Gossypium hirsutum L.) is one of the world's most important fiber crops, accounting for more than 90% of all cotton production. While their wild progenitors have relatively short and coarse, often tan-colored fibers, modern cotton cultivars possess longer, finer, stronger, and whiter fiber. In this study, the wild and cultivated cottons (YU-3 and TM-1) selected show significant differences on fibers at 10 day post-anthesis (DPA), 20 DPA and mature stages at the morphological level. In order to explore the effects of domestication, reveal molecular mechanisms underlying these phenotypic differences and better inform our efforts to further enhance cotton fiber quality, an iTRAQ-facilitated proteomic methods were performed on developing fibers...

Forensic medicine experts are well aware of blunt abdominal trauma, which often lead to death because of serious internal organ injury with severe blood loss. Sometimes careful examination of such cases may reveal some other underlying conditions, such as an existing disease that had contributed to the death or life-threatening complications. Our article presents a rare case of spontaneous hepatic rupture and intraperitoneal hemorrhage in a 32-year-old primigravida and her 29-week fetus, which was a result of hemolysis, elevated liver enzymes, and low platelet count syndrome...

BACKGROUND: Modic changes (MC) are associated with low back pain (LBP). In this study, we compared changes in size and type of MC, after a single intravenous infusion of 5 mg zoledronic acid (ZA) or placebo, among chronic LBP patients with MC on magnetic resonance imaging (MRI), and evaluated whether the MRI changes correlate with symptoms. METHODS: All patients (N = 19 in ZA, 20 in placebo) had MRI at baseline (0.23-1.5 T) and at one year (1.5-3 T). We evaluated the level, type and volume of all the MC...

Plant-derived compounds limiting mycotoxin contamination are currently of major interest in food and feed production. However, their potential application requires an evaluation of their effects on fungal secondary metabolism and membrane effects. In this study, different strains of Fusarium culmorum and F. graminearum sensu stricto were exposed to trans-cinnamic and chlorogenic acids on solid YES media. Fusaria produced phenolic acids, whose accumulation was lowered by exogenous phenolic compounds. In addition, fungi reduced exogenous phenolic acids, leading either to their conversion or degradation...

Titanium miniplates and screws are commonly used for fixation of jaw fractured or osteotomies. Despite the opinion of their biocompatibility, in clinical practice symptoms of chronic inflammation around the fixation develop in some patients, even many years after the application of miniplates and screws. The cause of these complications is still an unanswered question. Taking into account that oxidative stress is one of the toxic action of titanium, we have evaluated the antioxidant barrier as well as oxidative stress in the erythrocytes, plasma and periosteum covering the titanium fixation of the jaw...

Cholecystectomy is the treatment of choice for acute cholecystitis but the management of high-risk surgical patients is a difficult dilemma. Percutaneous cholecystostomy (PC) could represent a safer and less invasive option. The aim of the study was to assess the outcomes of PC in high-risk patients. This is a retrospective single-center study; data were collected from our hospital electronic record system. From February 2009 to March 2014, there were 753 patients admitted with acute cholecystitis. Of these 39 were considered high risk for surgery and underwent PC during their hospital stay...

Bone loss occurs frequently following allogeneic haematopoietic stem cell transplantation (alloSCT). The Australasian Leukaemia and Lymphoma Group conducted a prospective phase II study of pretransplant zoledronic acid (ZA) and individualised post-transplant ZA to prevent bone loss in alloSCT recipients. Patients received ZA 4 mg before conditioning. Administration of post-transplant ZA from days 100 to 365 post alloSCT was determined by a risk-adapted algorithm based on serial bone density assessments and glucocorticoid exposure...

Congenital disorders of glycosylation (CDG) are a rapidly expanding group of inherited metabolic disorders with highly variable clinical presentations caused by deficient glycosylation of proteins and/or lipids. CDG-IIh is a very rare subgroup of CDG caused by mutations in the conserved oligomeric Golgi (COG) complex gene, COG8, and so far, only two cases have been reported in the medical literature. Here, we describe an 8-year-old Korean boy with psychomotor retardation, hypotonia, failure to thrive, elevated serum liver enzymes, microcephaly, and talipes equinovarus...

Bisphosphonates are well known inhibitors of osteoclast activity and thus may be employed to influence osteoblast activity. The present study was designed to evaluate the in vivo effects of zoledronic acid (ZA) on the proliferation and osteoblastic commitment of mesenchymal stem cells (MSC) in osteoporotic patients. We studied 22 postmenopausal osteoporotic patients. Densitometric, biochemical, cellular and molecular data were collected before as well as after 6 and 12 months of ZA treatment. Peripheral blood MSC-like cells were quantified by colony-forming unit fibroblastic assay; their osteogenic differentiation potential was evaluated after 3 and 7 days of induction, respectively...

INTRODUCTION: There is an increasing number of adrenal being tumours discovered incidentally during imaging examinations performed for many different indications. Radiological findings suggesting adrenal pathology may be caused by true adrenal tumours or by other retroperitoneal masses. Generally, the larger the tumour, the higher the possibility of adrenal cancer. MATERIAL AND METHODS: Analysis of our data - 139 operations performed over 11 years (2004-2014) in patients with tumours in the adrenal area larger than 5 cm...

Specific genetic polymorphisms (SNPs) have been correlated with the development of bisphosphonate-related osteonecrosis of the jaw (BRONJ) in small series. We screened 140 myeloma patients (36 patients with and 104 without BRONJ) for the presence of previously identified SNPs in PPARG and CYP2C8 genes. All the patients received exclusively zolendronic acid (ZA) therapy and were followed prospectively for BRONJ. SNPs in both genes were associated with a higher risk of development of early BRONJ, occurring within less than 2 years of ZA therapy (59% vs...
