Recent studies have identified a number of transcriptional regulators, including E2A, early B-cell factor 1 (EBF1), FOXO1, and paired box gene 5 (PAX5), that promote early B-cell development. However, how this ensemble of regulators mechanistically promotes B-cell fate remains poorly understood. Here we demonstrate that B-cell development in FOXO1-deficient mice is arrested in the common lymphoid

Two series of C3-benzamido and O2-anion-substituted galactopyranosides were synthesized and studied as binders to arginine-rich proteins galectin-1, -3, -7, -8N (N-terminal domain), and -9N (N-terminal domain). The first series had a 4-methylbenzamide at C3 and the anionic O2-substituent was varied. The second series varied the 4-substituent of the C3-benzamide, whereas the anionic O2 substituent

Hereditary complete deficiency of complement component C1q is associated with a high prevalence of systemic lupus erythematosus and increased susceptibility to severe recurrent infections. An 11-year-old girl was screened for immunodeficiency due to a history of recurrent meningitis and pneumonia. Immunologic studies revealed absence of classic pathway hemolytic activity and undetectable levels of

This paper provides a systematic review of scholarly literature concerning the enforcement of children’s rights in the classroom context and school management. The literature review is based on a systematic review methodology the authors developed drawing on the methods and guidelines used in the medical sciences over the last 15 years. Forty-two articles published between 1990 and 2014 were selec

Even though recent studies suggest that a high intake of heme iron is associated with several types of cancer, epidemiological studies in relation to gastric cancer (GC) are lacking. Our previous results show a positive association between red and processed meat and non cardia gastric cancer, especially in Helicobacter pylori infected subjects. The aim of the study is to investigate the associatio

Aging of the hematopoietic stem cell compartment is believed to contribute to the onset of a variety of age-dependent blood cell pathophysiologies. Mechanistic drivers of hematopoietic stem cell (HSC) aging include DNA damage accumulation and induction of tumor suppressor pathways that combine to reduce the regenerative capacity of aged HSCs. Such mechanisms do not however account for the change i

The diagnosis of pulmonary tuberculosis (TB) relies on the bacteriological examination of sputum. However, microscopy of smears made directly from sputum has a low sensitivity and there is an urgent need for improved methods. We have compared microscopy of smears made directly from sputum with microscopy after liquefaction of sputum with household bleach (NaOCl) and concentration of bacteria by ce

The lack of human resources is one of the main bottlenecks to achieving the Millennium Development Goals on maternal and child health. A coherent national policy, recognized across government, needs to be in place to overcome this especially in countries severely affected by HIV/AIDS. Such a policy should cover selection of pre-service students, the qualifications of trainers and training sites, s

The binding of a nitroxide spin-labeled analog of N-acetyllactosamine to galectin-3, a mammalian lectin of 26 kD size, is studied to map the binding sites of this small oligosaccharide on the protein surface. Perturbation of intensities of cross-peaks in the (15)N heteronuclear single quantum coherence (HSQC) spectrum of full-length galectin-3 owing to the bound spin label is used qualitatively to

Insulin sensitivity and secretion are related in a curvilinear inverse asymptotic function. However, the signaling factors mediating this relation are not known. In this study, we explored whether circulating glucose, lipids or two adipocyte-derived hormones, leptin and adiponectin, are related to the curvilinear function between insulin sensitivity and secretion in subjects with normal glucose to

In cystic fibrosis (CF) colonization of the airways with Pseudomonas aeruginosa is a major cause of deterioration and death. Host defence fails to clear the invading bacteria, which results in a chronic destructive inflammatory process. This thesis deals with factors in the interaction between bacteria and host defence that determine the extent of tissue damage caused by the bacteria. (I) Autoant

Cells of the exocrine pancreas produce digestive enzymes potentially harmful to the intestinal mucosa. Dopamine has been reported to protect against mucosal injury. In looking for the source of dopamine in the small intestine, we found that the duodenal juice contains high levels of dopamine and that the pancreas itself has a high dopamine [and dihydroxyphenylalanine (dopa)] content that does not

Chronic obstructive pulmonary disease (COPD) is a debilitating respiratory disease and one of the leading causes of morbidity and mortality worldwide. It is characterized by persistent respiratory symptoms and airflow limitation due to abnormalities in the lower airway following consistent exposure to noxious particles or gases. Acute exacerbations of COPD (AECOPD) are characterized by increased c

Climate warming is expected to accelerate glacier retreat and shift hydrological regime, which poses great threat to regional water resources in terms of amount, variability, and quality. This is especially true in arid regions with glaciers such as the Central Asia. However, few models manage to mimic both glacier runoff and surface changes with adequate performance. To narrow this gap, we integ
