Unlabelled: To examine the value of surfactant protein D and KL-6 as markers for the diagnosis and the severity of interstitial pneumonia caused by measles infection, surfactant protein D, KL-6 and lactic acid dehydrogenase were measured serially in three patients with measles complicated by interstitial pneumonia as compared to ten measles infected patients without interstitial pneumonia. The serum surfactant protein D and KL-6 levels were higher in patients with measles and interstitial pneumonia as compared to those with measles without interstitial pneumonia. In patients with measles and interstitial pneumonia, the respiratory distress and the alveolar-arterial oxygen differences improved after steroid pulse therapy while the serum surfactant protein D level decreased dramatically under the cut-off level and earlier than the KL-6 level. On the contrary, the serum KL-6 level increased transiently and it took longer to decrease below the cut-off level as compared to the pattern observed for serum surfactant protein D. The serum lactic acid dehydrogenase level changes were between those of the surfactant protein D and KL-6 levels.
Conclusion: Surfactant protein D and KL-6 are easily measured and useful markers for the diagnosis of interstitial pneumonia caused by measles infection. Early decrease of surfactant protein D contrasts with the transient increase of KL-6 levels after prednisolone pulse therapy.

Groundnut fodder was utilized as a bioresource for the production of cellulases through solid state fermentation (SSF). Aspergillus unguis was initially grown on modified groundnut fodder for cellulase production and the fodder was hydrolyzed by the crude cellulase extract into fermentable hydrolyzate. The highest titer of Filter paperase (FPase), Carboxymethyl cellulase (CMCase), β-glucosidase, and protein content were found to be 11.

Background: In biomanufacturing of surface-active agents, such as rhamnolipids, excessive foaming is a significant obstacle for the development of high-performing bioprocesses. The exploitation of the inherent tolerance of Pseudomonas putida KT2440, an obligate aerobic bacterium, to microaerobic conditions has received little attention so far. Here low-oxygen inducible promoters were characterized in biosensor strains and exploited for process control under reduction of foam formation by low aeration and stirring rates during biosynthesis of rhamnolipids.

Background: Neonatal respiratory distress syndrome (NRDS), one of the main causes of neonatal death, is clinically characterized by progressive dyspnea and cyanosis 1 to 2 h after birth. Corticosteroids are commonly used to prevent NRDS in clinical. However, the protective mechanism of the corticosteroids remains largely unclear.

Modification of silica interfaces by covalent attachment of functional ligands is a primary means of controlling the interfacial chemistry of porous silicas used in separations, environmental cleanup, and biosensing. Recently, modification of hydrophobic, -alkyl-silane-functionalized interfaces has been achieved through self-assembly of zwitterionic phospholipids or mixed-charged surfactants to form "hybrid bilayers", producing interfaces that mimic lipid-bilayer partitioning and provide shape-selective partitioning of aromatic hydrocarbons. Charged headgroups, however, introduce electrostatic interactions that strongly influence the retention of ionizable solutes and require careful control over pH and ionic strength in the solution phase.
