Published: January 2012

Pulmonary surfactant is a complex surface-active substance comprised of key phospholipids and proteins that has many essential functions. Surfactant's unique composition is integrally related to its surface-active properties, its critical role in host defense, and emerging immunomodulatory activities ascribed to surfactant lipids. Together these effector functions provide for lung stability and protection from a barrage of potentially virulent infectious pathogens.

The severe climate change has caused a drastic water level disparity around the globe, which eventually has been one of the biggest problems of this era related to land degradation. This has caused the multidimensional impact on ecology, the environment, and their components. Algae, one of the ancient micro-engineers, are involved in the functioning of soil microcosm.

Pulmonary alveolar proteinosis (PAP) is a rare disease characterised by excessive accumulation of surfactant components in alveolar macrophages, alveoli, and peripheral airways. The accumulation of surfactant is associated with only a minimal inflammatory response but can lead to the development of pulmonary fibrosis. Three clinical forms of PAP are distinguished - primary, secondary and congenital.

Background: The conversion of primary bile acids to secondary bile acids by the gut microbiota has been implicated in colonic inflammation. This study investigated the role of gut microbiota related bile acid metabolism in colonic inflammation in both patients with inflammatory bowel disease (IBD) and a murine model of dextran sulfate sodium (DSS)-induced colitis.

Methods: Bile acids in fecal samples from patients with IBD and DSS-induced colitis mice, with and without antibiotic treatment, were analyzed using ultraperformance liquid chromatography-mass spectrometry (UPLC-MS).

Unlabelled: Fibroblasts are considered a key player in the wound healing process. Although this cellular family is constituted by several distinct subtypes, dermal fibroblasts are crucial thanks to their ability to secrete pro-regenerative growth factors, extracellular matrix (ECM) proteins and their immune and anti-inflammatory role. Sophorolipids (SL), sophorosides (SS) and glucolipids (G), mono-unsaturated (C18:1) or saturated (C18:0), glycolipids derived from microbial fermentation of wild type or engineered yeast , constitute a novel sustainable class of bio-based chemicals with interesting physicochemical characteristics, which allow them to form soft diverse structures from hydrogels to vesicles, micelles or complex coacervates with potential interest in skin regeneration applications.

The continuous contamination of heavy metals (HMs) in our ecosystem due to industrialization, urbanization and other anthropogenic activities has become a serious environmental constraint to successful crop production. Lead (Pb) toxicity causes ionic, oxidative and osmotic injuries which induce various morphological, physiological, metabolic and molecular abnormalities in plants. Polyethylene glycol (PEG) is widely used to elucidate drought stress induction and alleviation mechanisms in treated plants.
