When B12 therapy fails: two case reports of intravenous vitamin B12 resistance in pernicious anemia

Khyber Medical University Journal
BACKGROUND: Pernicious anemia is an autoimmune disorder causing vitamin B12 deficiency resulting from impaired absorption caused by intrinsic factor absence. Positive parietal cell and intrinsic factor antibodies confirm the diagnosis.

Consistency of objective Bayes factors as the model dimension grows

, 2010
In the class of normal regression models with a finite number of regressors, and for a wide class of prior distributions, a Bayesian model selection procedure based on the Bayes factor is consistent [Casella and Moreno J. Amer. Statist. Assoc. 104 (2009)

Self-Calibration Technique for 3-point Intrinsic Alignment Correlations in Weak Lensing Surveys

, 2011
The intrinsic alignment (IA) of galaxies has been shown to be a significant barrier to precision cosmic shear measurements. (Zhang, 2010, ApJ, 720, 1090) proposed a self-calibration technique for the power spectrum to calculate the induced gravitational ...

Intrinsic Disorder in Transcription Factors [PDF]

Biochemistry, 2006
Intrinsic disorder (ID) is highly abundant in eukaryotes, which reflect the greater need for disorder-associated signaling and transcriptional regulation in nucleated cells. Although several well-characterized examples of intrinsically disordered proteins in transcriptional regulation have been reported, no systematic analysis has been reported so far.

Coagulation Factor XII Levels and Intrinsic Thrombin Generation in Multiple Sclerosis

Frontiers in Neurology, 2018
BackgroundFactor XII (FXII) activation initiates the intrinsic (contact) coagulation pathway. It has been recently suggested that FXII could act as an autoimmunity mediator in multiple sclerosis (MS). FXII depositions nearby dentritic cells were detected
