Abstract
BACKGROUND The protective role of mildly elevated bilirubin against CVD and diabetes mellitus type 2 (DMT2) is associated with a favorable lipid phenotype. As the mechanistic understanding of this protection in humans remains elusive, we aimed to assess the metabolomics profile of mildly hyperbilirubinemic (Gilbert's syndrome; GS) individuals especially targeting lipid catabolism. METHODS AND RESULTS Using NMR serum metabolomics of 56 GS individuals and 56 age and gender-matched healthy controls, GS individuals demonstrated significantly greater concentrations of acetylcarnitine (+20%, p < 0.001) and the ketone bodies, 3-hydroxybutyric acid (+132%, p < 0.001), acetoacetic acid (+95%, p < 0.001) and acetone (+46%, p < 0.001). Metabolites associated with an increased mitochondrial lipid metabolism such as citrate (+15%, p < 0.001), anaplerotic amino acid intermediates and creatinine were significantly greater and creatine significantly reduced in GS individuals. Stimulators of lipid catabolism including AMPK (+59%, p < 0.001), pPPARα (+24%, p < 0.001) and T3 (+9%, p = 0.009) supported the metabolomics data while concomitantly blood glucose and insulin (-33%, p = 0.002) levels were significantly reduced. We further showed that the increased lipid catabolism partially mediates the favorable lipid phenotype (lower triglycerides) of GS individuals. Increased trimethylamine (+35%, p < 0.001) indicated changes in trimethylamine metabolism, an emerging predictor of metabolic health. CONCLUSION We showed an enhanced lipid catabolism in mildly hyperbilirubinemic individuals, novel evidence as to why these individuals are leaner and protected against chronic metabolic diseases emphasizing bilirubin to be a promising future target in obese and dyslipidemia patients.

Abstract
![]()
We have recently
presented an Automated Quantification Algorithm
(AQuA) and demonstrated its utility for rapid and accurate absolute
metabolite quantification in 1H NMR spectra in which positions
and line widths of signals were predicted from a constant metabolite
spectral library. The AQuA quantifies based on one preselected signal
per metabolite and employs library spectra to model interferences
from other metabolite signals. However, for some types of spectra,
the interspectral deviations of signal positions and line widths can
be pronounced; hence, interferences cannot be modeled using a constant
spectral library. We here address this issue and present an improved
AQuA that handles interspectral deviations. The improved AQuA monitors
and characterizes the appearance of specific signals in each spectrum
and automatically adjusts the spectral library to model interferences
accordingly. The performance of the improved AQuA was tested on a
large data set from plasma samples collected using ethylenediaminetetraacetic
acid (EDTA) as an anticoagulant (n = 772). These
spectra provided a suitable test system for the improved AQuA since
EDTA signals (i) vary in intensity, position, and line width between
spectra and (ii) interfere with many signals from plasma metabolites
targeted for quantification (n = 54). Without the
improvement, ca. 20 out of the 54 metabolites would have been overestimated.
This included acetylcarnitine and ornithine, which are considered
particularly difficult to quantify with 1H NMR in EDTA-containing
plasma. Furthermore, the improved AQuA performed rapidly (<10 s
for all spectra). We believe that the improved AQuA provides a basis
for automated quantification in other data sets where specific signals
show interspectral deviations.

Abstract
Hemangiomas are tumours originating from the vascular endothelium and can be found throughout the body. These are relatively common in the head and neck regions but very rarely seen in sinonasal region. In the nose and sinuses tumours typically are seen on the septum or lateral nasal wall (1-4). These tumours can be quite vascular and bleed during attempted resection. Incomplete resection does result in residual disease or recurrence so the best approach to achieve complete resection is important.

Abstract
The objective of the present study was to evaluate the effect of omega-3 and omega-6 PUFA enriched diet on plasma IGF-1 and testosterone concentrations, puberty, sperm fatty acid profile and semen quality in male buffalo. Eighteen male buffalo calves were distributed randomly in three different groups and fed concentrate mixture along with green fodder and wheat straw in 50:40:10 ratios as per requirements. Basis ration of animals in group I was supplemented with 4% of prilled fat (PFA), while in group II and group III were added 4.67% of Calcium salt from Soybean (CaSFA) and Linseed oil (CaLFA), respectively. Male buffalo fed omega-3 PUFA high diet significantly increased concentrations of IGF-1 and testosterone in plasma as compared to two other diets (p<0.05). The age of puberty and scrotal circumference significantly increased by dietary fat effect (p<0.05) of which n-3 PUFA enriched diet (CaLFA) had the largest influence as compared to other diets (PFA and CaSFA). Feeding of n-3 PUFA rich diet significantly increased the DHA (C22:6n-3) content in sperm (p<0.05), which contributed to increased fluidity of plasma membrane, elevated quality of sperm (motility, viability) and in vitro fertility (plasma membrane integrity, acrosome integrity) in both fresh and post-thawing semen. These findings indicate that feeding of n-3 PUFA enriched diet increased IGF-1 and testosterone secretion, reduced pubertal age and improved both fresh and post-thawing semen quality in male buffalo.

Abstract
A convenience sample of 164 adult patients with 185 glass-caused wounds who presented to an emergency department (ED) and consented to a radiograph was prospectively studied. The purpose was to determine the characteristics of wounds at high risk for foreign body (FB) and the predictive value of patient FB sensation and probing wound exploration for FB retention. Retained glass was located in 28 (15%) wounds. Motor vehicle as a mechanism of injury (P=.003), head as a location (P=.035), and puncture as wound type (P=.002) were more likely to be associated with retained FBs (chi2 analysis). Patients with wounds with glass were more likely to have a positive perception of a foreign body (41%) than those with no glass (17%) (P=.005). The positive predictive value of patient perception was 31%; negative predictive value was 89%. In five cases, wound exploration was negative and subsequent radiograph was positive for FB. In one of these cases, a 4-mm glass FB was removed; in the other four, no FB was found. In conclusion, head wounds resulting from motor vehicle accidents or puncture wounds are more likely to harbor retained glass FBs. Patients with glass FB in wounds are more likely to have a positive perception of FB; however, a positive perception has a low predictive value of glass FB. In this series, a negative wound exploration made the presence of retained FB greater than 2 mm less likely but did not rule out the presence of retained glass.

Abstract
The effects of porcine neuropeptide Y (NPY) on electrically evoked release of [3H]norepinephrine ([3H]NE) and [3H]acetylcholine ([3H]ACh) were investigated in isolated preparations of the rat lower urinary tract. In the urethra, NPY (0.02-0.5 microM) decreased the release of [3H]NE in a dose-dependent manner (10-53%). In the bladder base the inhibitory effect of NPY on [3H]NE release was not dose dependent. A low concentration (0.1 microM) decreased the release (38%), whereas a high concentration (0.5 microM) had no effect. However, in atropine-treated preparations, 0.5 microM NPY elicited a significant inhibition (43%). These observations suggest that 0.5 microM NPY elicits two opposing actions: a direct inhibitory action on adrenergic terminals and an indirect disinhibitory action to eliminate heterosynaptic cholinergic inhibition of [3H]NE release. In both tissues the action of NPY on [3H]NE release was not significantly modified by the alpha-adrenergic blocking agent yohimbine (1 microM). [3H]ACh release in the bladder body was not altered by 0.1 microM NPY but was suppressed (39%) by 1 microM NPY. The effect of NPY (1 microM) on [3H]ACh release was dependent on the frequency of stimulation. NPY suppressed the release at 2-Hz stimulation but had no significant effect at 20 Hz. These results suggest that NPY may have an important role in the neural regulation of the lower urinary tract by exerting differential effects on the release of cholinergic and adrenergic transmitters via autoinhibition and heterosynaptic interactions.
