In this study, 2 types of solidified noncentrifugal brown sugars (W-NCS and P-NCS) were prepared from the whole stalk and separated pith, respectively, of raw sugarcane (Saccharum officinarum L.). These products were discriminated in terms of their quality attributes, including color, sugars and minerals composition, taste, aroma, and antioxidant activity. The brown color of P-NCS was clearly different compared with that of W-NCS with a color difference value (ΔE(*) ) of 9.36. There was no difference in the sugars and minerals composition between the 2 types of sugar, which led to very similar taste profiles...

We developed two new FRET imaging measures for intramolecular FRET biosensors, called linearly proportional (LP) and highly contrasting (HC) measures, which can be easily calculated by the fluorescence intensities of donor and acceptor as a ratio between their weighted sums. As an alternative to the conventional ratiometric measure, which non-linearly depends on the fraction of active molecule, we first developed the LP measure, which is linearly proportional to the fraction of active molecules. The LP measure inherently unmixes bleed-through signals and is robust against fluorescence noise...

Forest regeneration following timber harvest is a principal source of habitat for early-successional birds and characterized by influxes of early-successional vegetation and residual downed woody material. Early-successional birds may use harvest residues for communication, cover, foraging, and nesting. Yet, increased market viability of woody biomass as bioenergy feedstock may intensify harvest residue removal. Our objectives were to: 1) evaluate effects of varying intensities of woody biomass harvest on the early-successional bird community; and (2) document early-successional bird use of harvest residues in regenerating stands...

BACKGROUND: Neonatal hypoglycaemia is common, affecting up to 15% of newborns, and can cause brain damage. Currently, there are no strategies, beyond early feeding, to prevent neonatal hypoglycaemia. Our aim was to determine a dose of 40% oral dextrose gel that will prevent neonatal hypoglycaemia in newborn babies at risk. METHODS AND FINDINGS: We conducted a randomised, double-blind, placebo-controlled dose-finding trial of buccal dextrose gel to prevent neonatal hypoglycaemia at two hospitals in New Zealand...

BACKGROUND: Whilst causes of hepatic artery thrombosis (HAT) after liver transplantation (LT) are multifactorial, early HAT (E-HAT) remains pertinent complication impacting on graft and patient survival. Currently there is no screening tool that would identify patients with increased risk of developing E-HAT. METHODS: We analyzed the native procoagulant state of LT recipients, identified through pretransplant thromboelastographic (TEG) data among other known risk factors, to identify risk factors for E-HAT...

Ketamine is often added to opioids in patient-controlled analgesia devices. We tested whether in surgical patients, ketamine added to an opioid patient-controlled analgesia decreased pain intensity by ≥25%, cumulative opioid consumption by ≥30%, the risk of postoperative nausea and vomiting by ≥30%, the risk of respiratory adverse effects by ≥50%, and increased the risk of hallucination not more than 2-fold. In addition, we searched for evidence of dose-responsiveness. Nineteen randomized trials (1349 adults, 104 children) testing different ketamine regimens added to various opioids were identified through searches in databases and bibliographies (to 04...

A model was set up to predict the differentiation patterns based on the data extracted from FTIR spectroscopy. For this reason, bone marrow stem cells (BMSCs) were differentiated to primordial germ cells (PGCs). Changes in cellular macromolecules in the time of 0, 24, 48, 72, and 96h of differentiation, as different steps of the differentiation procedure were investigated by using FTIR spectroscopy. Also, the expression of pluripotency (Oct-4, Nanog and c-Myc) and specific genes (Mvh, Stella and Fragilis) were investigated by real-time PCR...

As an integral glycoprotein on the surface of endothelial cells, thrombomodulin (TM) has very high affinity for thrombin. TM has been regarded to be a marker of endothelial damage since it can be released during endothelial cell injury. In this work, a highly sensitive fluorescence method for the quantitative detection of TM was developed. TM antibody (Ab) and bovine serum albumin (BSA) were bound on gold nanoparticles (AuNPs) to construct BSA-AuNPs-Ab nanocomposites and they were characterized by transmission electron microscope and UV-vis spectrophotometry...

Color is famous for not existing in the external world: our brains create the perception of color from the spatial and temporal patterns of the wavelength and intensity of light. For an intangible quality, we have detailed knowledge of its origins and consequences. Much is known about the organization and evolution of the first phases of color processing, the filtering of light in the eye and processing in the retina, and about the final phases, the roles of color in behavior and natural selection. To understand how color processing in the central brain has evolved, we need well-defined pathways or circuitry where we can gauge how color contributes to the computations involved in specific behaviors...

Humans are a remarkable species, especially because of the remarkable properties of their brain. Since the split from the chimpanzee lineage, the human brain has increased three-fold in size and has acquired abilities for vocal learning, language and intense cooperation. To better understand the molecular basis of these changes is of great biological and biomedical interest. However, all the about 16 million fixed genetic changes that occurred during human evolution are fully correlated with all molecular, cellular, anatomical and behavioral changes that occurred during this time...

Despite decades of intense study, the functions of sleep are still shrouded in mystery. The difficulty in understanding these functions can be at least partly attributed to the varied manifestations of sleep in different animals. Daily sleep duration can range from 4-20 hrs among mammals, and sleep can manifest throughout the brain, or it can alternate over time between cerebral hemispheres, depending on the species. Ecological factors are likely to have shaped these and other sleep behaviors during evolution by altering the properties of conserved arousal circuits in the brain...

The maintenance of monocytes, macrophages, and dendritic cells (DCs) involves manifold pathways of ontogeny and homeostasis that have been the subject of intense study in recent years. The concept of a peripheral mononuclear phagocyte system continually renewed by blood-borne monocytes has been modified to include specialized DC pathways of development that do not involve monocytes, and longevity through self-renewal of tissue macrophages. The study of development remains difficult owing to the plasticity of phenotypes and misconceptions about the fundamental structure of hematopoiesis...

Environmental enrichment (EE) gives laboratory animals opportunities to engage in species-specific behaviors. However, the effects of EE devices on normal physiology and scientific outcomes must be evaluated. We hypothesized that the spectral transmittance (color) of light to which rats are exposed when inside colored enrichment devices (CED) affects the circadian rhythms of various plasma markers. Pair-housed male Crl:SD rats were maintained in ventilated racks under a 12:12-h light:dark environment (265.0 lx; lights on, 0600); room lighting intensity and schedule remained constant throughout the study...

The population of the United States is predicted to age dramatically over the next few decades; as such older patients will comprise an increasing proportion of the injured populations. Due to multiple comorbidities and frailty, the old and very old are at greater risk for mortality than younger patients. To identify predictors of inhospital mortality in these patients, we performed a retrospective cohort study at our Level 1 trauma center. Between April 2009 and October 2014, we identified 193 trauma patients aged 80 years and older admitted to the intensive care unit...

Consensus is lacking for ideal management of mild traumatic brain injury (mTBI) with intracranial hemorrhage (ICH). Patients are often monitored in the intensive care unit (ICU) without additional interventions. We sought to identify admission variables associated with a favorable outcome (ICU admission for 24 hours, no neurosurgical interventions, no complications or mortality) to divert these patients to a non-ICU setting in the future. We reviewed all patients with mTBI [Glasgow Coma Scale (GCS) = 13-15] and concomitant ICH between July 1, 2012, and June 30, 2015...

Although the true incidence of postoperative dysphagia after cardiac surgery is unknown, it has been reported to occur in 3 to 21.6 per cent of patients. Historically, dysphagia has been associated with increased surgical complications and prolonged hospital stay. This study aimed to evaluate the costs and outcomes associated with dysphagia after cardiac surgery. Patients undergoing nonemergent, nontransplant cardiac operations between June 2013 and June 2014 were eligible for inclusion. Independent predictors of cost were identified through a multivariate linear regression model...

Intraosseous (IO) needle placement is an alternative for patients with difficult venous access. The purpose of this retrospective study was to examine indications and outcomes associated with IO use at a Level 1 trauma center (January 2008-May 2015). Data points included demographics, time to insertion, intravenous (IV) access points, indications, infusions, hospital and intensive care unit length of stay, and mortality. Of 68 patients with IO insertion analyzed (63.2% blunt trauma, 29.4% penetrating trauma, and 7...

Elderly trauma patients may be at increased risk for underassessment and inadequate pain control in the emergency department (ED). We sought to characterize risk factors for oligoanalgesia in the ED in elderly trauma patients and determine whether it impacts outcomes in elderly trauma patients. We included elderly patients (age ≥55 years) with Glasgow Coma Scale scores 13 to 15 and Injury Severity Score (ISS) ≥9 admitted through the ED at a Level I trauma center. Patient characteristics and outcomes were compared between those who reported pain and received analgesics medication in the ED (MED) and those who did not (NO MED)...
