BACKGROUND: Little information is available regarding penetrance of the 1q21.1 copy number variants (CNVs). We explored the clinical significance of 1q21.1 microdeletion or microduplication. METHODS: In four families, chromosome karyotype was analyzed using G-banding karyotype analysis technology, CNVs were detected using array-comparative genomic hybridization (aCGH), and then quantitative polymerase chain reaction (qPCR) was used to validate candidate CNVs. Sequence signature in the breakpoint region was analyzed using UCSC databases...

Microcystins are a group of cyclic heptapeptide toxins produced by cyanobacteria. More than 100 microcystin analogues have been detected, among which microcystin-LR is the most abundant and toxic variant. Present study was designed to reveal whether potential human carcinogen microcystin-LR could imbalance the glycolytic-oxidative-nitrosative status of heart, kidney and spleen of mice and also to explore the amelioratory effect of coenzyme Q10 on microcystin-LR induced toxicity. Microcystin-LR was administered at a dose of 10 μg/kg bw/day, ip for 14 days in male mice...

BACKGROUND: Aging human skin undergoes significant morphological and functional changes such as wrinkle formation, reduced wound healing capacity, and altered epidermal barrier function. Besides known age-related alterations like DNA-methylation changes, metabolic adaptations have been recently linked to impaired skin function in elder humans. Understanding of these metabolic adaptations in aged skin is of special interest to devise topical treatments that potentially reverse or alleviate age-dependent skin deterioration and the occurrence of skin disorders...

OBJECTIVE: The hip-joint capsule is exposed to increased tension forces during canine hip dysplasia, resulting in inflammation of the capsular tissue. It has been postulated that inflammation is associated with an increased nerve-distribution density. Therefore, it could be supposed that the nerve-distribution density in the hip-joint capsule is higher in dogs with dysplastic hip compared to healthy dogs. MATERIAL AND METHODS: In 16 Labrador Retriever dogs that had been euthanised due to unrelated reasons, the hip joints were classified as normoplastic (group 1, n = 18) or dysplastic (group 2, n = 14) based on radiography...

The International Council for Harmonisation Quality Guideline 10 (ICH Q10) describes the Pharmaceutical Quality System (PQS), indicating it is intended to apply throughout a product's lifecycle, in conjunction with good manufacturing practice (GMP) requirements, in order to achieve quality in a consistent and reproducible manner. Implementation of an effective PQS is essential for a company to achieve product realization, establish and maintain a state of control, and facilitate continual improvement (1). When changes are made during the commercial life of a product, an effective PQS, product and process understanding, and use of quality risk management should ensure that product quality, patient safety, and adequate supply to patients are maintained; this, according to ICH Q10-Annex 1, should provide companies the opportunity to manage post-approval changes (PAC) with reduced regulatory oversight (1)...

Metabolic cold adaptation (MCA) is a controversial hypothesis suggesting that cold adapted species display an elevated metabolic rate (MR) compared to their warm climate relatives. Here we test for the presence of MCA within 65 species of drosophilid flies reared under common garden conditions. MR was measured at both 10 and 20°C for both sexes and data was analyzed in relation to the natural thermal environment of these species. We found considerable interspecific variation in MR ranging from 1.34 to 8.99 µW mg(-1) at 10°C...

Aging may enhance both oxidative stress and bone-marrow mesenchymal stem-cell (MSC) differentiation into adipocytes. That reduces osteoblastogenesis, thus favoring bone-mass loss and fracture, representing an important worldwide health-issue, mainly in countries with aging populations. Intake of antioxidant products may help to retain bone-mass density. Interestingly, a novel olive-pomace physical treatment to generate olive oil also yields by-products rich in functional antioxidants. Thus, diet of postmenopausal women was supplemented for two months with one of such by-products (distillate 6; D6), being rich in squalene...

BACKGROUND: Gaucher disease (GD) is caused by mutations in the GBA1 gene which encodes lysosomal β-glucocerebrosidase (GCase). In GD, partial or complete loss of GCase activity causes the accumulation of the glycolipids glucosylceramide (GlcCer) and glucosylsphingosine in the lysosomes of macrophages. In this manuscript, we investigated the effects of glycolipids accumulation on lysosomal and mitochondrial function, inflammasome activation and efferocytosis capacity in a THP-1 macrophage model of Gaucher disease...

The percentage of the plasma oxidized form of coenzyme Q10 in the total amount of coenzyme Q10 (%CoQ10) is a useful marker of oxidative stress in the circulation. Plasma free fatty acids and their composition can be used as markers of tissue oxidative damage, as demonstrated in patients suffering from a wide variety of diseases and in humans and rats under oxidative stress. Edaravone was approved for the treatment of stroke in Japan in 2001 and its mechanism of action is based on scavenging lipid peroxyl radicals...

Early spring phytoplankton blooms can occur at very low water temperatures but they are often decoupled from bacterial growth, which is assumed to be often temperature controlled. In a previous mesocosm study with Baltic Sea plankton communities, an early diatom bloom was associated with a high relative abundance of Glaciecola sequences (Gammaproteobacteria), at both low (2°C) and elevated (8°C) temperatures, suggesting an important role for this genus in phytoplankton-bacteria coupling. In this study, the temperature-dependent dynamics of free-living Glaciecola spp...

The polyol pathway called as sorbitol way is a small part of glycose metabolism. The pathway is regarded as an important element in the pathogenesis of various diabetic complications in individuals with diabetes mellitus. The pathway plays a crucial role in hyperglycemia. The polyol pathway contains two enzymes as aldose reductase (AR) and sorbitol dehydrogenase (SDH). In the present study, AR and SDH were purified from sheep liver by using simple chromatographic methods. AR was purified with a yield of 2.11% and approximately 162 fold and SDH was purified with a yield of 0...
