Recent research indicates that the human microbiota play key roles in maintaining health by providing essential nutrients, providing immune education, and preventing pathogen expansion. Processes underlying the transition from a healthy human microbiome to a disease-associated microbiome are poorly understood, partially because of the potential influences from a wide diversity of bacterium-derived compounds that are illy defined. Here, we present the analysis of peptidic small molecules (SMs) secreted from bacteria and viewed from a temporal perspective...

Stephen P Newman
Pulmonary drug delivery is relatively complex because the respiratory tract has evolved defense mechanisms to keep inhaled drug particles out of the lungs and to remove or inactivate them once deposited. In addition to these mechanical, chemical and immunological barriers, pulmonary drug delivery is adversely affected by the behavioral barriers of poor adherence and poor inhaler technique. Strategies to mitigate the effects of these barriers include use of inhaler devices and formulations that deliver drug to the lungs efficiently, appropriate inhaler technique and improved education of patients...

REVIEW
Jeff C Leggit
Paronychia is inflammation of the fingers or toes in one or more of the three nail folds. Acute paronychia is caused by polymicrobial infections after the protective nail barrier has been breached. Treatment consists of warm soaks with or without Burow solution or 1% acetic acid. Topical antibiotics should be used with or without topical steroids when simple soaks do not relieve the inflammation. The presence of an abscess should be determined, which mandates drainage. There are a variety of options for drainage, ranging from instrumentation with a hypodermic needle to a wide incision with a scalpel...

Drug design and discovery remains a popular topic of study to many students interested in visible, real-world applications of the chemical sciences. It is important that laboratory experiments detailing the early stages of drug discovery incorporate both compound design and an exploration of ligand/receptor interactions. Molecular modeling is widely employed in research endeavors seeking to predict the activity of potential compounds prior to synthesis and can therefore be used to illustrate these concepts...

Environmental education has long been recognized as critical for achieving environmental awareness, values and attitudes, skills and behaviour consistent with sustainable development and for effective participation in environmental decision-making. Since the Declaration of the 1972 United Nations Conference on the Human Environment concerns about marine pollution and ecotoxicology, among other environmental challenges, should be included in environmental education. However, in the more than forty years since this significant environmental Declaration, marine education has struggled to find a place in the school curriculum of most countries, even though issues such as climate change, chemical contamination of marine environments, coastal eutrophication, and seafood safety continue to threaten human and other species' well-being...

RATIONALE: Impact of ambient pollution upon children's asthma may differ by sex, and exposure dose and timing. Psychosocial stress can also modify pollutant effects. These associations have not been examined for in utero ambient nitrate exposure. OBJECTIVES: We implemented Bayesian distributed lag interaction models (BDLIMs), to identify sensitive prenatal windows for the influence of NO3- on child asthma, accounting for effect modification by sex and stress. METHODS: Analyses included 752 mother-child dyads...
