PURPOSE: To clarify the relationship between whole body sagittal radiographic parameters and health related quality of life (HRQOL) in patients with spinal disease, and further analyse such relationship based on the pelvic incidence (PI) value. METHODS: 100 patients (mean age: 64.4 years, M/F = 50/50) with lumbar degenerative disease or spinal deformity were prospectively investigated. Following Oswestry Disability Index (ODI) and Scoliosis Research Society Score 22 (SRS-22) questionnaire, whole body sagittal x-ray parameters were measured using a slot-scanning 3D x-ray imager (EOS)...

BACKGROUND/PURPOSE: Ankle sprains are common and potentially disabling musculoskeletal injuries that often lead to chronic ankle instability (CAI). CAI has been linked to impairments in postural and neuromuscular control; however, inconsistent findings have been reported. Individuals who experience a lateral ankle sprain, but do not develop instability, termed copers, may adapt different neuromuscular control strategies after injury. This study aimed to compare postural control and electromyographic (EMG) activity of hip and ankle muscles during the performance of the Star Excursion Balance Test (SEBT) in subjects with and without CAI...

Two kinds of clinoptilolite-rich tuffs from the state of Sonora (Mexico), previously treated with NaCl solution and then modified with thiourea, were investigated to remove Cd2+ from aqueous solution in a fixed-bed column system. Experiments were conducted with a 30 mg L-1 Cd2+ solution at a pH value of 5 and three-bed heights of sodium- and thiourea-modified clinoptilolite-rich tuffs. The experimental data were examined with the Bed Depth Service Time model (BDST), the Thomas model, and a mass balance approach...

Vortex storm overflow is an interesting and useful technical solution, especially important in storm and combined sewage systems. However, there are no methods of this device dimensioning, which would be mathematically simple and properly precise physically. Such a method has been proposed in this paper, on the basis of investigations performed for the vortex separators and vortex flow controls. The essence of this method relies on the kinematic model of the velocity field and energy balance of the inflowing stream and dissipation...

The response of tumor intracellular pH to a pharmacological challenge could help identify aggressive cancer. Chemical exchange saturation transfer (CEST) is an MRI contrast mechanism that is dependent on intracellular pH (pHi ). pHi is important in the maintenance of normal cell function and is normally maintained within a narrow range by the activity of transporters located at the plasma membrane. In cancer, changes in pHi have been correlated with both cell proliferation and cell death. Quercetin is a bioflavonoid and monocarboxylate transporter (MCT) inhibitor...

Neurological complications of cardiac surgery have a large effect on patient outcomes. In this review, the value of several modes of central nervous system monitoring for improving perioperative care is critiqued. The electroencephalogram (EEG) has been used as a means for detecting brain ischemia. Even though EEG changes are specific for ischemia, the reliability is tempered by many confounding factors. The effectiveness of the processed EEG for ensuring amnesia during surgery is controversial, but it may have value for optimizing anesthetic dose and thus reducing the risk for delirium...

Measurements of the center of pressure (CoP) acquired with a person positioned on a force plate is one of the most commonly used tool to investigate a balance. Several studies show a significant degradation of the body stability after the age of 60 years, however, these conclusions were based on a limited number of indicators. Also, these studies don't take into consideration the change in stability in very old age groups and sex of subjects.In our study, not all parameters lead to the same conclusions. The vast majority of the results didn't show any statistically significant difference when considering the age groups...

Serotonin (5-HT) plays a regulatory role in coordinating the neural circuits regulating energy balance, with differences in both 5-HT availability at the synapse and the activity of 5-HT receptors mediating anorectic (via POMC/CART activation) and orexigenic (via NPY/AgRP activation) responses. In conditions of overweight and obesity the control of energy balance is clearly deregulated, and serotonergic modulation appears to make a significant contribution to weight gain. Fluoxetine (FLX), a selective serotonin reuptake inhibitor (SSRI) that increases 5-HT availability in the synaptic cleft may thus have potential effects on energy balance...

OBJECTIVE: The management of Women With Epilepsy (WWE) in pregnancy is a challenge that demands balancing the risks of Major Congenital Malformation (MCM) on one hand with adequate seizure control on the other. While most studies have analysed the risks of Anti-Epileptic Drugs (AED) exposure in the first trimester, AED changes during the second and third trimester and their effects on fetal outcome has not been studied adequately. MATERIALS AND METHODS: Data of WWE who were prospectively followed up and completed pregnancy with live birth under the Kerala registry of epilepsy and pregnancy (KREP) between 1998 and 2014 were analysed...

Sarcopenia is defined as a combination of low muscle mass with low muscle function. The term was first used to designate the loss of muscle mass and performance associated with aging. Now, recognized causes of sarcopenia also include chronic disease, a physically inactive lifestyle, loss of mobility, and malnutrition. Sarcopenia should be differentiated from cachexia, which is characterized not only by low muscle mass but also by weight loss and anorexia. Sarcopenia results from complex and interdependent pathophysiological mechanisms that include aging, physical inactivity, neuromuscular compromise, resistance to postprandial anabolism, insulin resistance, lipotoxicity, endocrine factors, oxidative stress, mitochondrial dysfunction, and inflammation...

The nutritional regulation of protein and amino acid balance in human skeletal muscle carried out by the authors with Mike Rennie is reviewed in the context of a simple physiological model for the regulation of the maintenance and growth of skeletal muscle, the "Bag Theory." Beginning in London in the late 1970s the work has involved the use of stable isotopes to probe muscle protein synthesis and breakdown with two basic experimental models, primed-dose continuous tracer infusions combined with muscle biopsies and arterio-venous (A-V) studies across a limb, most often the leg, allowing both protein synthesis and breakdown as well as net balance to be measured...

BACKGROUND: Fever control plays a key role in therapy of patients with acute brain injury. The infusion of cold saline could serve as an alternative or additional method for targeted temperature management. However, it is difficult to estimate the amount of fluid required to achieve normothermia merely on the basis of body weight. There is no standardized load management regarding the administration of cold saline, and no closed-loop systems based on continuous temperature-controlled feedback are available...

While nutrient loads from anthropogenic sources upset aquatic ecosystem balance, Wolffia arrhiza (duckweed) has capacity to purge nutrient-rich water if continuously harvested. The nutrients accumulated in biomass have potential as soil fertility amendments. The objective of this study was to determine changes in release of nitrogen (N) and phosphorus (P), and the fate of P in soils after duckweed biomass amendment. An incubation experiment was conducted at 25 °C using three soils amended with proportions equivalent to 501, 1002 and 1503 mg N kg-1 and 62, 124 and 186 mg P kg-1 ...

Lipomyces starkeyi is an oil-producing yeast that can produce triacylglycerol (TAG) from glycerol as a carbon source. The TAG was mainly produced after nitrogen depletion alongside reduced cell proliferation. To obtain clues for enhancing the TAG production, cell metabolism during the TAG-producing phase was characterized by metabolomics with 13 C labeling. The turnover analysis showed that the time constants of intermediates from glycerol to pyruvate (Pyr) were large, whereas those of tricarboxylic acid (TCA) cycle intermediates were much smaller than that of Pyr...

INTRODUCTION/BACKGROUND: Osteoporosis is a common disorder and is associated with an increased risk of bone fracture. Falls are a proximate cause of a high proportion of medical costs and mortality. Improving balance can reduce the risk of falls and improve health outcomes, especially for the at-risk population of people with osteoporosis and osteopenia. The FrameWorksTM exercise program is a formal, standardized, informational and interventional 10-month exercise program. The purpose of this study was to quantitatively assess the improvement in standing balance, functional reach, and overall confidence in balance after participating in the 10-month program...

BACKGROUND: Selective serotonin reuptake inhibitors (SSRIs) are amongst the most prescribed antidepressants for adolescents with depressive symptoms and major depressive disorder. However, SSRIs have significant shortcomings as a first-line treatment considering that not all patients respond to these antidepressants. Amongst paediatric populations, meta-analyses indicate that up to approximately 40% of patients do not respond, and for those who do show benefit, there is substantial heterogeneity in response onset...

The purpose of this study was to evaluate absorbable polyethylene glycol (PEG)-based synthetic hydrogel as a sealant for retinal breaks in rhegmatogenous retinal detachment (RD). A three-port, 25-gauge vitrectomy was performed on nine Dutch pigmented rabbit eyes. Subsequently, RD was induced by creating a retinal break. The retina was then reattached by fluid-air exchange. In six of nine eyes (RD-PEG group), PEG sealant was applied to completely cover the retinal breaks, and then photopolymerized with light; thereafter, intravitreous air was replaced with balanced salt solution (BSS)...
