TL;DR: The official International Dairy Federation method for determination of the peroxide value of anhydrous milk fat was extended to poultry, meat, fish, and vegetable oils and the ferrous oxidation-xylenol orange method was modified to make it simpler and more rapid.
Abstract: The official International Dairy Federation method for determination of the peroxide value of anhydrous milk fat was extended to poultry, meat, fish, and vegetable oils. The ferrous oxidation-xylenol orange method for determination of peroxide values of liposomes and lipoproteins was modified to make it simpler and more rapid. These 2 spectrophotometric methods were used successfully to determine the peroxide values of beef, chicken, butter, fish, and vegetable products. The results in most cases were consistent with those obtained by using the AOAC Official Method. The spectrophotometric methods have an assay time of less than 10 min, require < or = 0.3 g fat, and are capable of determining peroxide values as low as 0.1 mequiv/kg of sample.

TL;DR: The aspergilli comprise a diverse group of filamentous fungi spanning over 200 million years of evolution, and a comparative study with Aspergillus fumigatus and As pergillus oryzae, used in the production of sake, miso and soy sauce, provides new insight into eukaryotic genome evolution and gene regulation.
Abstract: The aspergilli comprise a diverse group of filamentous fungi spanning over 200 million years of evolution. Here we report the genome sequence of the model organism Aspergillus nidulans, and a comparative study with Aspergillus fumigatus, a serious human pathogen, and Aspergillus oryzae, used in the production of sake, miso and soy sauce. Our analysis of genome structure provided a quantitative evaluation of forces driving long-term eukaryotic genome evolution. It also led to an experimentally validated model of mating-type locus evolution, suggesting the potential for sexual reproduction in A. fumigatus and A. oryzae. Our analysis of sequence conservation revealed over 5,000 non-coding regions actively conserved across all three species. Within these regions, we identified potential functional elements including a previously uncharacterized TPP riboswitch and motifs suggesting regulation in filamentous fungi by Puf family genes. We further obtained comparative and experimental evidence indicating widespread translational regulation by upstream open reading frames. These results enhance our understanding of these widely studied fungi as well as provide new insight into eukaryotic genome evolution and gene regulation.

TL;DR: These findings suggest that vascular RAGE is a target for inhibiting pathogenic consequences of Aβ-vascular interactions, including development of cerebral amyloidosis.
Abstract: Amyloid-β peptide (Aβ) interacts with the vasculature to influence Aβ levels in the brain and cerebral blood flow, providing a means of amplifying the Aβ-induced cellular stress underlying neuronal dysfunction and dementia. Systemic Aβ infusion and studies in genetically manipulated mice show that Aβ interaction with receptor for advanced glycation end products (RAGE)-bearing cells in the vessel wall results in transport of Aβ across the blood-brain barrier (BBB) and expression of proinflammatory cytokines and endothelin-1 (ET-1), the latter mediating Aβ-induced vasoconstriction. Inhibition of RAGE-ligand interaction suppresses accumulation of Aβ in brain parenchyma in a mouse transgenic model. These findings suggest that vascular RAGE is a target for inhibiting pathogenic consequences of Aβ-vascular interactions, including development of cerebral amyloidosis.

TL;DR: At comparable sedation levels, dexmedetomidine-treated patients spent less time on the ventilator, experienced less delirium, and developed less tachycardia and hypertension.
Abstract: Context γ-Aminobutyric acid receptor agonist medications are the most commonly used sedatives for intensive care unit (ICU) patients, yet preliminary evidence indicates that the α 2 agonist dexmedetomidine may have distinct advantages Objective To compare the efficacy and safety of prolonged sedation with dexmedetomidine vs midazolam for mechanically ventilated patients Design, Setting, and Patients Prospective, double-blind, randomized trial conducted in 68 centers in 5 countries between March 2005 and August 2007 among 375 medical/surgical ICU patients with expected mechanical ventilation for more than 24 hours Sedation level and delirium were assessed using the Richmond Agitation-Sedation Scale (RASS) and the Confusion Assessment Method for the ICU Interventions Dexmedetomidine (02-14 μg/kg per hour [n = 244]) or midazolam (002-01 mg/kg per hour [n = 122]) titrated to achieve light sedation (RASS scores between −2 and +1) from enrollment until extubation or 30 days Main Outcome Measures Percentage of time within target RASS range Secondary end points included prevalence and duration of delirium, use of fentanyl and open-label midazolam, and nursing assessments Additional outcomes included duration of mechanical ventilation, ICU length of stay, and adverse events Results There was no difference in percentage of time within the target RASS range (773% for dexmedetomidine group vs 751% for midazolam group; difference, 22% [95% confidence interval {CI}, −32% to 75%]; P = 18) The prevalence of delirium during treatment was 54% (n = 132/244) in dexmedetomidine-treated patients vs 766% (n = 93/122) in midazolam-treated patients (difference, 226% [95% CI, 14% to 33%]; P Conclusions There was no difference between dexmedetomidine and midazolam in time at targeted sedation level in mechanically ventilated ICU patients At comparable sedation levels, dexmedetomidine-treated patients spent less time on the ventilator, experienced less delirium, and developed less tachycardia and hypertension The most notable adverse effect of dexmedetomidine was bradycardia Trial Registration clinicaltrialsgov Identifier: NCT00216190Published online February 2, 2009 (doi:101001/jama200956)

TL;DR: It is demonstrated that increased plasma concentrations of Ang II have profound and rapid effects on vascular pathology when combined with hyperlipidemia, in the absence of hemodynamic influences.
Abstract: Increased plasma concentrations of angiotension II (Ang II) have been implicated in atherogenesis. To examine this relationship directly, we infused Ang II or vehicle for 1 month via osmotic minipumps into mature apoE(-/-) mice. These doses of Ang II did not alter arterial blood pressure, body weight, serum cholesterol concentrations, or distribution of lipoprotein cholesterol. However, Ang II infusions promoted an increased severity of aortic atherosclerotic lesions. These Ang II-induced lesions were predominantly lipid-laden macrophages and lymphocytes; moreover, Ang II promoted a marked increase in the number of macrophages present in the adventitial tissue underlying lesions. Unexpectedly, pronounced abdominal aortic aneurysms were present in apoE(-/-) mice infused with Ang II. Sequential sectioning of aneurysmal abdominal aorta revealed two major characteristics: an intact artery that is surrounded by a large remodeled adventitia, and a medial break with pronounced dilation and more modestly remodeled adventitial tissue. Although no atherosclerotic lesions were visible at the medial break point, the presence of hyperlipidemia was required because infusions of Ang II into apoE(+/+) mice failed to generate aneurysms. These results demonstrate that increased plasma concentrations of Ang II have profound and rapid effects on vascular pathology when combined with hyperlipidemia, in the absence of hemodynamic influences.
