The Arg92Cys colipase polymorphism impairs function and secretion by increasing protein misfolding
Journal of Lipid Research, 2013 Colipase is essential for efficient fat digestion. An arginine-to-cysteine polymorphism at position 92 of colipase (Arg92Cys) associates with an increased risk for developing type-2 diabetes through an undefined mechanism. To test our hypothesis that the

The flux-dependent X-ray time lags in NGC 4051 [PDF]
, 2013 We present an analysis of the X-ray time lags for the highly variable Seyfert 1 galaxy NGC 4051, based on a series of XMM-Newton observations taken in 2009. We investigate the Fourier frequency dependent time lags in the light curves between the 0.3--1.0

The changing X-ray time lag in MCG-6-30-15 [PDF]
, 2014 MCG-6-30-15 is one of the most observed Narrow Line Seyfert 1 galaxies in the X-ray band. In this paper we examine the X-ray time lags in this source using a total of 600 ks in observations (440 ks exposure) taken with the XMM-Newton telescope (300 ks in

Exploiting Kinetic Features of ORAC Assay for Evaluation of Radical Scavenging Capacity
Antioxidants, 2023 The analysis and interpretation of data retrieved from Oxygen Radical Absorbance Capacity (ORAC) assays represent a challenging task. ORAC indexes originate from different mathematical approaches often lacking correct elucidation of kinetic features ...

Journal for the Anthropology of North America, 2019 AbstractThis article draws on ethnographic fieldwork with emergency responders in southern Arizona and northern Sonora that I conducted between 2015 and 2017 and my professional training and volunteer service as a paramedic. In retelling an episode when an aspiring wildland firefighter collapsed and died in a remote desert in the southwestern United ...

Revealing the X-ray source in IRAS 13224-3809 through flux-dependent reverberation lags [PDF]
, 2013 IRAS 13224-3809 was observed in 2011 for 500 ks with the XMM-Newton observatory. We detect highly significant X-ray lags between soft (0.3 - 1 keV) and hard (1.2 - 5 keV) energies. The hard band lags the soft at low frequencies (i.e. hard lag), while the
