The monocyte-derived cytokine response in whole blood from preterm newborns against sepsis-related bacteria is similar to term newborns and adults.

Introduction: Sepsis is characterized by a dysregulated innate immune response. It is a leading cause of morbidity and mortality in newborns, in particular for newborns that are born premature. Although previous literature indicate that the pro-inflammatory response may be impaired in preterm newborns, serum levels of monocyte-derived cytokines, such as TNF-α and IL-6, vary highly between newborns and can reach adult-like concentrations during sepsis.

Capsaicin for non-allergic rhinitis.

Background: There are many forms of rhinitis. Patients are diagnosed with non-allergic rhinitis when anatomic, infectious and allergic aetiologies have been excluded. The symptoms, including nasal congestion, blockage or obstruction, clear rhinorrhoea, sneezing and, less frequently, nasal itching, can range from mild to debilitating.

The Na+/H+ exchanger present in trout erythrocyte membranes is not responsible for the amiloride-insensitive Na+/Li+ exchange activity.

The protein responsible for the Na+/Li+ exchange activity across the erythrocyte membrane has not been cloned or isolated. It has been suggested that a Na+/H+ exchanger could be responsible for the Na+/Li+ exchange activity across the erythrocyte membrane. Previously, we reported that in the trout erythrocyte, the Li+/H+ exchange activity (mediated by the Na+/H+ exchanger beta NHE) and the Na+/Li+ exchange activity respond differently to cAMP, DMA (dimethyl-amiloride) and O2.

The effect of 2-O-stearoyl-glycerol 1,3-bisphosphate on the demineralization of dental enamel in vitro.

Parts of the buccal and lingual enamel surfaces of sound human third molars were treated with a test compound, and the non-treated parts served as control. After the treatment both parts were demineralized, and the artificial caries lesions were analyzed by means of quantitative microradiography. Treatment during only 1 minute with an aqueous solution of 1.

Radiochemical determination of the metabolic activity of collagen in mature dentin.

Tritiated proline was administered to domestic cats during the development of their permanent premolars. The metabolic activity of collagen in the mature premolar dentin was determined by quantitating the amount of tritiated hydroxyproline in the dentin as a function of time. It has been demonstrated that the metabolic activity of the dentinal collagen was extremely low and remained within the experimental error for a period of 45 weeks.
