The article offers information associated with allergy diagnostics that help complement a patient's history and aid in the diagnosis and management of allergic diseases. Topics discussed include use of specific IgE tests aid in the diagnosis of allergen sensitization, history of allergy testing and issues associated with maximizing efficiency of component resolved diagnostics and protein families for pet allergens and their impact on clinical strategies to manage allergic sensitization.

ABSTRACT: Assessing nutrient stores in avian species is important for understanding the extent to which body condition influences success or failure in life‐history events. We evaluated predictive models using morphometric characteristics to estimate total body lipids (TBL) and total body protein (TBP), based on traditional proximate analyses, in spring migrating lesser snow geese (Anser caerulescens caerulescens) and Ross's geese (A. rossii). We also compared performance of our lipid model with a previously derived predictive equation for TBL developed for nesting lesser snow geese. We used external and internal measurements on 612 lesser snow and 125 Ross's geese collected during spring migration in 2015 and 2016 within the Central and Mississippi flyways to derive and evaluate predictive models. Using a validation data set, our best performing lipid model for snow geese better predicted TBL (root mean square error [RMSE] of 23.56) compared with a model derived from nesting individuals (RMSE = 48.60), suggesting the importance of season‐specific models for accurate lipid estimation. Models that included body mass and abdominal fat deposit best predicted TBL determined by proximate analysis in both species (lesser snow goose, R2 = 0.87, RMSE = 23.56: Ross's geese, R2 = 0.89, RMSE = 13.75). Models incorporating a combination of external structural measurements in addition to internal muscle and body mass best predicted protein values (R2 = 0.85, RMSE = 19.39 and R2 = 0.85, RMSE = 7.65, lesser snow and Ross's geese, respectively), but protein models including only body mass and body size were also competitive and provided extended utility to our equations for field applications. Therefore, our models indicated the importance of specimen dissection and measurement of the abdominal fat pad to provide the most accurate lipid estimates and provide alternative dissection‐free methods for estimating protein.

The article provides information about cholesterol. It is defined as the most highly decorated small molecule in biology. Eventhough the cells have the ability to manufacture cholesterol, the liver synthesizes most of what is present in our body, and humans derive about one-fourth of their cholesterol from dietary sources. The laboratory measurement of cholesterol is a surrogate marker for lipoprotien particles, which can be considered a proxy for the degree of atheromatous deposits.

The article offers information on a research headed by Benjamin Van Mooy, a geochemist at the Woods Hole Oceanographic Institution, on substitute lipids in relation to building cell membranes. Van Mooy states that these lipids are the most abundant membrane molecules in the sea. It indicates that scientists have believed until now that membranes surrounding cells solely depending on phospholipids which contain phosphorus and other biochemical nutrients like nitrogen.
