To verify the idea that extracellular free oligosaccharides might be able to reflect the functional status of the endoplasmic reticulum (ER) and lysosomal-endosomal system, HPLC-profiles of serum-derived free oligosaccharides (FOS) in human healthy aging, acute myeloproliferative neoplasms, and cardiovascular pathologies were compared with intracellular glycans. After plasma deproteinization and FOS purification the oligosaccharides were labelled with anthranilic acid, separated into the neutral and charged with QAE Sephadex (Q25-120) chromatography and analysed using high-performance liquid chromatography (HPLC)...

INTRODUCTION: Moderate to heavy alcohol consumption is a risk factor for all-cause mortality and cancer incidence. Although cross-sectional data are available through national surveys, data on alcohol consumption in Alberta from a large prospective cohort were not previously available. The goal of these analyses was to characterize the levels of alcohol consumption among adults from the Alberta's Tomorrow Project in the context of cancer prevention guidelines. Furthermore, we conducted analyses to examine the relationships between alcohol consumption and other high-risk or risk-related behaviours...

Diabetes, as a chronic metabolic disease, can impair the immune function of monocytes/macrophages (MMs). However, it is unclear how MMs immune response to inflammation with the development of diabetes, and whether immune response around the inflammatory foci depends on the depth in tissue. Footpad provides a classical physiological site for monitoring cellular behavior during inflammation, but limited to the superficial dermis due to the strong scattering of footpad. Herein, we used confocal microscopy to monitor the motility of MMs in deeper tissue around inflammatory foci with the development of type 1 diabetic (T1D) mice through a swithable footpad skin optical clearing window...

BACKGROUND: Influenza A virus in swine (IAV-S) causes an acute respiratory disease of swine which results in great economic losses in pig production. Major control strategies include the use of killed vaccines (KV) in breeding females to confer passive immunity to their offspring. A bivalent H1N1 and H3N2 NS1-truncated live attenuated IAV-S vaccine has recently become available, which showed promising results in young pigs. OBJECTIVE: The aim of this study was to investigate the effect of an intranasal vaccination of newborn pigs with or without maternally derived antibodies (MDA) on virus shedding (via nasal swabs tested by virus isolation)...

Paroxysmal nocturnal hemoglobinuria (PNH) arises as a consequence of the non-malignant clonal expansion of one or more hematopoietic stem cells with an acquired somatic mutation of the PIGA gene.(1) Progeny of affected stem cells are deficient in glycosyl phosphatidylinositol-anchored proteins (GPI-APs). This deficiency is readily detected by flow cytometry. Though this seems straightforward, the clinical utility of this testing requires that the ordering clinician understand not only the characteristics of the test, but also the biology of the underlying disease, and the clinical and laboratory manifestations in the individual patient...

Glia scar is a pathological marker in late phase of brain ischemia disease, which constitutes a major physical biochemical barrier to impede axonal regrowth. Astrocytes are known to be critically involved in the formation of glial scar. However, their response to ischemia and their role in neuroprotection after central nervous system (CNS) injury are not completely clear. Recently, we have demonstrated for the first time that Ski was up-regulated in reactive astrocytes after spinal cord injury in vivo and in vitro, which indicates Ski may be a new molecule that control astrocytes biologic properties after CNS injury...

Osteosarcoma (OS) is the most common cancer of bone in children and young adults. Despite extensive research efforts, there has been no significant improvement in patient outcome for many years. An improved understanding of the biology of this cancer and how genes frequently mutated contribute to OS may help improve outcomes for patients. Whilst our knowledge of the mutational burden of OS is approaching saturation, our understanding of how these mutations contribute to OS initiation and maintenance is less clear...

Osteoarthritis (OA) is the most prevalent degenerative joint disease with multifactorial etiology caused by risk factors. The degradation of aggrecan by upregulated ADAMTS (a disintegrin and metalloproteinase with thrombospondin motifs) is the key event in the development of OA. ADAMTS-4 contributes to aggrecan degradation in human OA. Cysteine-rich angiogenic inducer 61 (Cyr61), which is associated with diseases related to chronic inflammation, is found in articular cartilage from patients with osteoarthritis and appears to suppress ADAMTS-4 activity, possibly leading to chondrocyte cloning...

Depression is known as one of important psychiatric disorders which could be associated with disability among various populations. Diagnostic and statistical manual of mental disorders, 4th edition (DSM-IV) and international statistical classification of diseases and related health problems (ICD-10) could be used as subjective diagnostic schemes for identification of mental disorders such as depression. Utilization of subjective diagnostic schemes are associated with limitations. Hence, it seems that employing of new diagnosis platforms is required...

Pesticides are widely used in agricultural fields to control plant diseases, weeds and pests, however, the unforeseeable consequences of releasing these compounds into the soil and their effects on terrestrial invertebrates are a matter of grave concern. The aim of this study was to determine the direct impact of two pesticides, KRAFT® 36 EC (an insecticide; a.i abamectin) and SCORE® (a fungicide; a.i. difenoconazole), on non-target terrestrial invertebrates. Ecotoxicological tests were performed to evaluate the chronic and acute toxicity of these compounds to a potworm (Enchytraeus crypticus), a collembolan (Folsomia candida) and a mite (Hypoaspis aculeifer)...
