Vitamin K Insufficiency in the Indian Population: Pilot Observational Epidemiology Study.

Background: The fat-soluble K vitamins K1 and K2 play an essential role in the blood coagulation cascade and are made available predominantly through selective dietary intakes. They are less known for their nonessential roles in a family of vitamin K-dependent proteins that promote various functions of organs and systems in the body. A lack of vitamin K can characterize vitamin and nutritional element insufficiency, which is different from a clinically apparent vitamin deficiency.

Evaluation of a Sclerotinia homoeocarpa Population with Multiple Fungicide Resistance Phenotypes Under Differing Selection Pressures.

Dollar spot, caused by Sclerotinia homoeocarpa, is one of the most significant diseases of cool-season turfgrass on golf courses. Resistance to the benzimidazole, dicarboximide, and succinate dehydrogenase inhibitor (SDHI) classes and reduced sensitivity to the sterol-demethylation inhibitor (DMI) in S. homoeocarpa populations have been widely reported in the United States.

The aim of the current study was to evaluate vitamin D and K status in children with low-energy fractures and in children without fractures.

Methods: The study group of 20 children (14 boys, 6 girls) aged 5 to 15 years old, with radiologically confirmed low-energy fractures was compared with the control group of 19 healthy children (9 boys, 10 girls), aged 7 to 17 years old, without fractures.

Differential effect of platelet-rich plasma fractions on β1-integrin signaling, collagen biosynthesis, and prolidase activity in human skin fibroblasts.

The study was conducted to evaluate the effects of platelet-rich plasma (PRP), supernatant of PRP (SPRP) obtained by centrifugation, and supernatant of activated PRP (SActi-PRP) obtained by Ca solution-treated PRP on collagen biosynthesis, prolidase activity, and β1-integrin signaling in cultured human skin fibroblasts. Incubation of fibroblasts with 5% PRP for 24 h contributed to ~5-fold increase in collagen biosynthesis compared to the control. In the cells treated with 5% of SPRP or SActi-PRP, collagen biosynthesis showed a 3-fold increase of the control.

Roles of Vitamins D and K, Nutrition, and Lifestyle in Low-Energy Bone Fractures in Children and Young Adults.

The research on skeletal system health in children and young adults, while recognizing the important role of calcium and vitamin D, goes beyond these nutritional standards. This review focuses on the role of vitamin K in combination with vitamin D and other factors in bone health. The current understanding is that maintaining bone health and prevention of low-energy fractures in any pediatric population includes nutritional factors combined with an active lifestyle.

Analysis of the lipid body proteome of the oleaginous alga Lobosphaera incisa.

Background: Lobosphaera incisa (L. incisa) is an oleaginous microalga that stores triacylglycerol (TAG) rich in arachidonic acid in lipid bodies (LBs). This organelle is gaining attention in algal research, since evidence is accumulating that proteins attached to its surface fulfill important functions in TAG storage and metabolism.

Evaluation of Treatment of Low-energy Distal Radial Fractures in Postmenopausal Women.

Background: Distal radial fractures are one of the most common injuries seen in traumatology. Most are treated conservatively with closed reduction and immobilisation in a plaster cast. However, this method does not always allow for achieving and maintaining normal fracture reduction in unstable fractures.

Antifungal mechanisms of ZnO and Ag nanoparticles to Sclerotinia homoeocarpa.

Fungicides have extensively been used to effectively combat fungal diseases on a range of plant species, but resistance to multiple active ingredients has developed in pathogens such as Sclerotinia homoeocarpa, the causal agent of dollar spot on cool-season turfgrasses. Recently, ZnO and Ag nanoparticles (NPs) have received increased attention due to their antimicrobial activities. In this study, the NPs' toxicity and mechanisms of action were investigated as alternative antifungal agents against S.

Association between Vitamin D Receptor Polymorphism and Serum Vitamin D Levels in Children with Low-Energy Fractures.

Objective: Fractures of bones, especially forearm fractures, are very common in children and their number is increasing. This study was designed to determine the impact of vitamin D serum levels and vitamin D receptor (VDR) polymorphisms on the occurrence of low-energy fractures in children.

Metabolome Analysis Reveals Betaine Lipids as Major Source for Triglyceride Formation, and the Accumulation of Sedoheptulose during Nitrogen-Starvation of Phaeodactylum tricornutum.

Oleaginous microalgae are considered as a promising resource for the production of biofuels. Especially diatoms arouse interest as biofuel producers since they are most productive in carbon fixation and very flexible to environmental changes in the nature. Naturally, triacylglycerol (TAG) accumulation in algae only occurs under stress conditions like nitrogen-limitation.

Molecular Mechanisms Involved in Qualitative and Quantitative Resistance to the Dicarboximide Fungicide Iprodione in Sclerotinia homoeocarpa Field Isolates.

The dicarboximide fungicide class is commonly used to control Sclerotinia homoeocarpa, the causal agent of dollar spot on turfgrass. Despite frequent occurrences of S. homoeocarpa field resistance to iprodione (dicarboximide active ingredient), the genetic mechanisms of iprodione resistance have not been elucidated.

Inhibition of TNF-α, IL-1α, and IL-1β by Pretreatment of Human Monocyte-Derived Macrophages with Menaquinone-7 and Cell Activation with TLR Agonists In Vitro.

Circulatory markers of low-grade inflammation such as tumor necrosis factor-alpha (TNF-α), interleukin-1 alpha (IL-1α), and interleukin-1 beta (IL-1β) positively correlate with endothelial damage, atheroma formation, cardiovascular disease, and aging. The natural vitamin K2-menaquinone-7 (MK-7) added to the cell culture of human monocyte-derived macrophages (hMDMs) at the same time as toll-like receptor (TLR) agonists did not influence the production of TNF-α. When the cells were pretreated up to 6 h with MK-7 before treatment with TLR agonists, MK-7 did not inhibit significantly the production of TNF-α after the TLR activation.

Assessment of Idiopathic Scoliosis Patients' Satisfaction with Thoracolumbar Brace Treatment.

Background: Bracing is the most efficient non-surgical method of treatment for idiopathic scoliosis patients with 25-45° curvature according to Cobb. The aim of the present study was to assess compliance of idiopathic scoliosis patients with medical instructions concerning the time patients should spend wearing orthopedic braces, patients' self-perceived health status and problems occurring in patients with idiopathic scoliosis.

Material And Methods: A total of 51 patients aged between 9 to 18 years (84% females) treated for adolescent idiopathic scoliosis with a thoracolumbar brace were asked to complete a survey titled ''The profile of quality of life with spine deformity".

Study of the protective effects of nootropic agents against neuronal damage induced by amyloid-beta (fragment 25-35) in cultured hippocampal neurons.

Background: Alzheimer's disease (AD) is a common neurodegenerative disorder, in which progressive neuron loss, mainly in the hippocampus, is observed. The critical events in the pathogenesis of AD are associated with accumulation of β-amyloid (Aβ) peptides in the brain. Deposits of Aβ initiate a neurotoxic "cascade" leading to apoptotic death of neurons.

Objectives: Lyme disease (LB) relatively commonly causes arthritis among patients, especially in LB endemic area. The aim of the study was to analyze the prevalence of LB in children with hip and knee effusion in the North Eastern region of Poland. Conclusions from our study should justify the need of taking into account LB in the diagnosis of hip or knee effusion in children.

A pleiotropic drug resistance transporter is involved in reduced sensitivity to multiple fungicide classes in Sclerotinia homoeocarpa (F.T. Bennett).

Dollar spot, caused by Sclerotinia homoeocarpa, is a prevalent turfgrass disease, and the fungus exhibits widespread fungicide resistance in North America. In a previous study, an ABC-G transporter, ShatrD, was associated with practical field resistance to demethylation inhibitor (DMI) fungicides. Mining of ABC-G transporters, also known as pleiotropic drug resistance (PDR) transporters, from RNA-Seq data gave an assortment of transcripts, several with high sequence similarity to functionally characterized transporters from Botrytis cinerea, and others with closest blastx hits from Aspergillus and Monilinia.

[Congenital insensitivity to pain].

Congenital insensitivity to pain belongs to rare diseases called hereditary sensory neuropathy (HSN). The disturbance of sense and secondary harms are creating clinical picture. The aim of this report was to describe therapeutic problems with which we met with a three siblings with congenital insensitivity to pain.

Epileptiform stimulus increases Homer 1a expression to modulate synapse number and activity in hippocampal cultures.

Neurons adapt to seizure activity structurally and functionally to attenuate hyperactive neural circuits. Homer proteins provide a scaffold in the postsynaptic density (PSD) by binding to ligands through an EVH1 domain and to other Homer proteins by a coiled-coil domain. The short Homer isoform 1a (H1a) has a ligand-binding domain but lacks a coiled-coil domain and thus acts in a dominant-negative manner to uncouple Homer scaffolds.

SUCROSE TRANSPORTER 5 supplies Arabidopsis embryos with biotin and affects triacylglycerol accumulation.

The Arabidopsis SUC5 protein represents a classical sucrose/H(+) symporter. Functional analyses previously revealed that SUC5 also transports biotin, an essential co-factor for fatty acid synthesis. However, evidence for a dual role in transport of the structurally unrelated compounds sucrose and biotin in plants was lacking.

Overexpression of ShCYP51B and ShatrD in Sclerotinia homoeocarpa isolates exhibiting practical field resistance to a demethylation inhibitor fungicide.

We investigated genetic factors that govern the reduced propiconazole sensitivity of Sclerotinia homoeocarpa field isolates collected during a 2-year field efficacy study on dollar spot disease of turf in five New England sites. These isolates displayed a >50-fold range of in vitro sensitivity to a sterol demethylation inhibitor (DMI) fungicide, propiconazole, making them ideal for investigations of genetic mechanisms of reduced DMI sensitivity. The CYP51 gene homolog in S.

The Association Between In Vitro Propiconazole Sensitivity and Field Efficacy of Five New England Sclerotinia homoeocarpa Populations.

Dollar spot (Sclerotinia homoeocarpa) is a major turfgrass disease requiring fungicide application to maintain acceptable conditions for golf. A 2-year field experiment was conducted to determine the association between field efficacy of propiconazole and in vitro fungicide sensitivity of isolates from five S. homoeocarpa populations.

Glycoconjugate markers of joint diseases.

A number of different types of glycoconjugate are found associated with joint tissue and fluids, comprising glycoproteins, glycolipids and glycosaminoglycans. Oligosaccharide chains of glycoconjugates are degraded by exoglycosidases, and the dominant exoglycosidase found in human blood, synovial fluid, the synovial membrane and chondrocytes of articular cartilage is HEX (N-acetyl-β-hexosaminidase). HEX is localized mostly intracellularly in synovial cells.
