New Research on Sexual Orientation and Gender Identity Discrimination: Effect of State Policy on Charges Filed at the EEOC.

In 2013, the Equal Employment Opportunity Commission (EEOC) began allowing anyone who believed that they experienced sexual orientation or gender identity (SOGI) discrimination to file charges of sex discrimination under Title VII of the Civil Rights Act. Very little is known about the impact of the EEOC's decision and whether it has enhanced protections for LGBT people. In this brief report, we present preliminary findings on trends and patterns in charge filing, paying particular attention to differences that emerge in charges filed in states with and without SOGI employment nondiscrimination laws.

Predicting the HILIC Retention Behavior of the N-Linked Glycopeptides Produced by Trypsin Digestion of Immunoglobulin Gs (IgGs).

The prediction of the retention behavior/time would facilitate the identification and characterization of glycoproteins, particularly the analytical challenges, such as the characterization of low-abundance glycoforms. This task is essential in the biotherapeutics industry, where the type and amount of glycosylation on recombinant IgG alter the efficacy, function, and immunogenicity. Models exist for the prediction of the hydrophilic interaction liquid chromatography retention of peptides and glycans.

Proteomics reveals localization of cuticular proteins in Anopheles gambiae.

Anopheles gambiae devotes over 2% of its protein coding genes to its 298 structural cuticular proteins (CPs). This paper provides new LC-MS/MS data on two adult structures, proboscises and palps, as well as three larval samples - 4th instar larvae, just their terminal segment, and a preparation enriched in their tracheae. These data were combined with our previously published results of proteins from five other adult structures, whole adults, and two preparations chosen for their relatively clean cuticle, the larval head capsules left behind after ecdysis and the pupal cuticles left behind after adult eclosion.

Peptide retention prediction using hydrophilic interaction liquid chromatography coupled to mass spectrometry.

A model that predicts retention for peptides using a HALO penta-HILIC column and gradient elution was created. Coefficients for each amino acid were derived using linear regression analysis and these coefficients can be summed to predict the retention of peptides. This model has a high correlation between experimental and predicted retention times (0.

Predicting the Retention Behavior of Specific -Linked Glycopeptides.

-Linked glycosylation is a common post-translational modification that can alter the overall structure, polarity, and function of proteins. Reverse-phase (RP) chromatography is the most common chromatographic approach to analyze -glycosylated peptides and their unmodified counterparts, even though this approach often does not provide adequate separation of these two species. Hydrophilic interaction liquid chromatography (HILIC) can be a solution to this problem, as the polar glycan interacts with the polar stationary phase and potentially offers the ability to resolve the peptide from its modified form(s).
