Tropical foliage is an alternative source for protein enrichment in the dairy ration. However, due to expensive, laborious, and time-consuming data-gathering method, its degradability database inclusion ration formulation still lacking. This study aims estimate tropical foliage's situ (RDP) using chemical compositions, vitro digestibilities, near infrared reflectance spectroscopy (NIRS) methods...

Near-infrared reflectance spectroscopy (NIRS) was used to predict the chemical composition, apparent digestibility and digestible nutrients and energy content of commercial extruded compound foods for dogs. Fifty-six foods of known chemical composition and in vivo apparent digestibility were analysed overall and 51 foods were used to predict gross energy digestibility and digestible energy cont...

We have developed a computational model to simulate hypoxia-ischaemia (HI) in the neonatal piglet brain. It has been extended from a previous model by adding the simulation of carotid artery occlusion and including pH changes in the cytoplasm. Here, simulations from the model are compared with near-infrared spectroscopy (NIRS) and phosphorus magnetic resonance spectroscopy (MRS) measurements fr...

Near-infrared spectroscopy (NIRS) has potential as a non-invasive brain monitor in a wide range of clinical scenarios. In the last decade, there has been a rapid expansion of clinical experience using NIRS to monitor cerebral oxygenation, particularly in cardiac surgery, where there is some evidence that NIRS-guided brain protection protocols might lead to a reduction in peri-operative neurolog...

BACKGROUND Working memory (WM) is a key function for various cognitive processes. Near-infrared spectroscopy (NIRS) is a powerful technique for noninvasive functional imaging. However, a study has yet to be published on the application of NIRS for evaluating WM performance. The objective was to evaluate NIRS for measuring WM performance. METHODS Subjects were trained to perform a visuospatial...

Introduction: Near Infrared Spectroscopy (NIRS) and BOLD fMRI measure complementary quantities relating to changes in the concentration of oxyand deoxyhemoglobin (HbO and HbR respectively) [1]. NIRS offers superior temporal resolution (40ms versus 2000ms), whereas BOLD offers superior spatial resolution and whole brain coverage. We are exploring the NIRS and BOLD relationship through simultaneo...

The attractive possibility of near infrared spectroscopy (NIRS) to noninvasively assess cerebral blood volume and oxygenation is challenged by the possible interference from extracranial tissues. However, to what extent this may affect cerebral NIRS monitoring during standard clinical tests is ignored. To address this issue, 29 healthy subjects underwent a randomized sequence of three maneuvers...

The periplasmic cytochrome cd1 nitrite reductase NirS occurring in denitrifying bacteria such as the human pathogen Pseudomonas aeruginosa contains the essential tetrapyrrole cofactors haem c and haem d1. Whereas the haem c is incorporated into NirS by the cytochrome c maturation system I, nothing is known about the insertion of the haem d1 into NirS. Here, we show by co-immunoprecipitation tha...

UNLABELLED Near infrared spectroscopy (NIRS) measures tissue oxygenation continuously at the bedside. Major disturbances of cerebral oxygenation can be detected by using NIRS, but the ability to observe smaller changes is poorly documented. Although anesthetics generally depress cerebral metabolism and enhance oxygen delivery, the administration of etomidate has been associated with cerebral de...

Group classification of tobacco blends is commonly performed using several different types of compositional data including tobacco compounds, additive or process components. But all of these wet chemistry methods are relatively time-consuming. A need exists for a fast and reliable procedure in order to determine the blend type. The purpose of this study was to assess the ability of near infrare...
