Shin Fujimaki, Tomoko Kuwabara
Diabetes mellitus is one of the most common metabolic diseases spread all over the world, which results in hyperglycemia caused by the breakdown of insulin secretion or insulin action or both. Diabetes has been reported to disrupt the functions and dynamics of mitochondria, which play a fundamental role in regulating metabolic pathways and are crucial to maintain appropriate energy balance. Similar to mitochondria, the functions and the abilities of stem cells are attenuated under diabetic condition in several tissues...

Instruments to measure movement abilities from a patient's perspective are generally unavailable across diverse cultures and languages. The aim of this study was to translate, culturally adapt, and validate the Italian version of the Outpatient Physical Therapy Improvement in Movement Assessment Log (OPTIMAL) confidence scale. This study was an observational multicenter study. The Italian version of the OPTIMAL confidence scale (OPTIMAL-I) was developed following forward-backward translation and pretesting with a small group of patients...

Molecules provide versatile building blocks, with a vast palette of functionalities and an ability to assemble via supramolecular and covalent bonding to generate remarkably diverse macromolecular systems. This is abundantly displayed by natural systems that have evolved on Earth, which exploit both supramolecular and covalent protocols to create the machinery of life. Importantly, these molecular assemblies deliver functions that are reproducible, adaptable, finessed and responsive. There is now a real need to translate complex molecular systems to surfaces and interfaces in order to engineer 21st century nanotechnology...

BACKGROUND: Motor performance is an important factor for health. Already in childhood, motor performance is associated with, e.g., obesity and risk factors for cardiovascular diseases. It is widely believed that the motor performance of children has declined over recent years. However, this belief is lacking clear evidence. The objective of this study was to examine trends in motor performance of first grade students during a period of 10 years (2006-2015). We examined trends in (a) aerobic fitness, (b) strength, (c) speed, and (d) balance for boys and girls separately and considered body mass index (BMI) as a potential confounder...

It was previously demonstrated that differentiation of some established breast epithelial cell lines requires confluence and stimulation with hydrocortisone, insulin and prolactin inducers. We and others previously demonstrated that E-cadherin engagement, which is favored under conditions of confluence, increases the levels and activity of the Rac small GTPase. To investigate the functional relationship between the transforming ability of Rac and its role as an integral component of the differentiative E-cadherin signaling pathway, we introduced a mutationally activated form of Rac, Rac(V12), into the mouse breast epithelium-derived cell line, HC11...

The kidneys play a major role in the regulation of acid-base balance by reabsorbing bicarbonate filtered by the glomeruli and excreting titratable acids and ammonia into the urine. In CKD, with declining kidney function, acid retention and metabolic acidosis occur, but the extent of acid retention depends not only on the degree of kidney impairment but also on the dietary acid load. Acid retention can occur even when the serum bicarbonate level is apparently normal. With reduced kidney function, acid transport processes in the surviving nephrons are augmented but as disease progresses ammonia excretion and, in some individuals, the ability to reabsorb bicarbonate falls, whereas titratable acid excretion is preserved until kidney function is severely impaired...

Older adults 65 years of age and older compose a great portion of the US population. Physiologic changes of aging that limit function and general quality of life occur at a faster rate as we get older. There is high-quality evidence that exercise activity has many favorable benefits for older adults. The ideal exercise program in older adults should include aerobic, resistance, flexibility, and balance training. The exercise recommendations should be individually tailored to the abilities, precautions, and goals of each person...

BACKGROUND: The effects of a stroke, such as hemiparesis, can severely hamper the ability to walk and to maintain balance during gait. Providing support to stroke survivors through a robotic exoskeleton, either to provide training or daily-life support, requires an understanding of the balance impairments that result from a stroke. Here, we investigate the differences between the paretic and non-paretic leg in making recovery steps to restore balance following a disturbance during walking...

Dietary plant cell wall carbohydrates are important in modulating the composition and metabolism of the complex gut microbiota, which can impact on health. Pectin is a major component of plant cell walls. Based on studies in model systems and available bacterial isolates and genomes, the capacity to utilize pectins for growth is widespread among colonic Bacteroidetes but relatively uncommon among Firmicutes. One Firmicutes species promoted by pectin is Eubacterium eligens. E. eligens DSM3376 utilizes apple pectin and encodes a broad repertoire of pectinolytic enzymes, including a highly abundant pectate lyase of around 200 kDa that is expressed constitutively...

Continuous renal replacement therapy (CRRT) in critically ill patients has significant impact on one's ability to provide efficient nutritional therapy. CRRT may help in the prevention of intestinal oedema and the maintenance of the proper function of the gastrointestinal tract by enabling strict control of the fluid balance. It facilitates early introduction of nutrition via the enteral route, as well as allowing for the composition of high-volume feeding mixtures. It is necessary to take into consideration that during CRRT, together with blood purification of toxic substances, nutritive elements are also eliminated to some extent (micro- and macronutrients)...

In recent years, graphene (G) and graphene oxide (GO) nanoparticles have begun to be applied in surgical implant surface modification. However, biosafety and antibacterial ability of G and GO are still unclear. In this study, the biosafety of G and GO in vitro was evaluated by co-culture with bone marrow mesenchymal stem cells (BMSCs) and biosafety in vivo was observed by implanting materials into mice muscle tissue. Biosafety results showed that 10 μg/ml was the safety critical concentration for G and GO...

Polylactic acid (PLA), dicalcium phosphate dihydrate (DCPD) and/or hydraulic calcium silicate (CaSi) have been used to prepare highly-porous scaffolds by thermally induced phase separation technique (TIPS). Three experimental mineral-doped formulations were prepared (PLA-10CaSi, PLA-5CaSi-5DCPD, PLA-10CaSi-10DCPD). Pure PLA scaffolds constituted the control group. Scaffolds were tested for their chemical-physical and biological properties, namely calcium release, alkalinizing activity, surface microchemistry and micromorphology by ESEM, apatite-forming ability by EDX, micro-Raman and IR spectroscopy, thermal properties by differential scanning calorimetry, mechanical properties by quasi-static parallel-plates compression testing, porosity by a standard water-absorption method and direct-contact cytotoxicity...

Background Until now, many studies have investigated the link between motor development and visual-spatial abilities in infancy and childhood. Most of these studies found evidence that there is such a link in typically developing children or children with locomotor delay. Only a few studies have tested the consequences of this link in children with abnormal visual development because of infantile esotropia. Moreover, little is known about the effects of late surgery on motor development. Patients and Methods We assessed the motor abilities of 3- to 7-year old children with severe deficits in stereopsis due to infantile esotropia (angle ≥ 12°) and typically developing children prior to and 12 to 16 months after surgery...

An important goal of human immunodeficiency virus (HIV) vaccine design is identification of strategies that elicit effective antiviral humoral immunity. One novel approach comprises priming with DNA and boosting with modified vaccinia Ankara (MVA) expressing HIV-1 Env on virus like particles. Here we evaluated whether the addition of a gp120 protein in alum or MVA expressed secreted gp140 (MVAgp140) could improve immunogenicity of a DNA prime - MVA boost vaccine. Five rhesus macaques per group received two DNA primes at weeks 0 and 8 followed by three MVA boosts (with or without additional protein or MVAgp140) at weeks 18, 26 and 40...

Balance ability among the elderly is a key component in the activities of daily living and is divided into two types: static and dynamic. For clinicians who wish to assess the risk of falling among their elderly patients, it is unclear if more than one type of balance test can be used to measure their balance impairment. In this study, we examined the association between static balance measures and two dynamic balance field tests. One hundred and twelve community-dwelling older adults (mean age 74.6) participated in the study...

The effect of vestibular rehabilitation (VR) on anxiety, dizziness and poor balance that developed after cochlear implant (CI) surgery is described. A 54-year-old woman, with profound hearing loss since the age of 2 years, underwent right CI surgery 2 years previously. On implant activation, the patient immediately felt dizziness and imbalance, which affected the ability to perform activities of daily living and increased anxiety to where the patient considered the CI removal. Prior to VR the patient was evaluated with the Dizziness Handicap Inventory and the Visual Vertigo Dizziness Questionnaire and clinically with the Zur Balance Scale and Video Head Impulse Test...
