Abstract
It has long been recognised that there are differences between human milk and infant formulas which lead to differences in health and nutrition for the neonate. In this study we examine and compare the peptide profile of human milk and an exemplar infant formula. The study identifies both similarities and differences in the endogenous and postdigestion peptide profiles of human milk and infant formula. This includes differences in the protein source of these peptides but also with the region within the protein producing the dominant proteins. Clustering of similar peptides around regions of high sequence identity and known bioactivity was also observed. Together the data may explain some of the functional differences between human milk and infant formula, while identifying some aspects of conserved function between bovine and human milks which contribute to the effectiveness of modern infant formula as a substitute for human milk.

Abstract
UNLABELLED The mechanisms underlying resistance to challenge by gastrointestinal nematode parasites in sheep are complex. Using DIGE, we profiled ovine lymph proteins in lambs with host resistance (R), resilience (Ri) or susceptibility (S) to a daily trickle challenge with the nematode Trichostrongylus colubriformis. Efferent intestinal lymph was collected prior to infection (day 1) and on days 5 and 10 post-infection. Eight proteins identified by LC-MS/MS, showed differences relating to host genotype. Of these, Serpin A3-3 and Serpin A3-7 have not been reported previously in the lymph proteome. Three acute phase proteins showed significant differences relating to interactions between breeding line and parasite challenge, including complement C3β, C3α and haptoglobin (Hp) β. In the R lambs C3α was significantly up regulated (P<0.05) on day 10, while in the Ri lambs Hp β was significantly down regulated (P<0.05). In the S lambs, levels of C3β were up regulated and levels of Hp β down regulated (both P<0.05) on day 10. Hence we demonstrate that acute phase inflammation proteins contribute to differences in the innate immune response of sheep to challenge by T. colubriformis. The findings may lead to the development of new approaches to combat nematode infestations in sheep production systems. BIOLOGICAL SIGNIFICANCE Breeding lines of sheep with resistance (R), resilience (Ri) or susceptibility (S) to nematode infections provide an experimental model to examine the biological mechanisms underlying the ability of some sheep to expel worms and remain healthy without the use of an anthelmintic. Using proteomics we identified differences in the expression of acute phase lymph proteins in the R, Ri and S lambs. The results will assist the development of alternative control strategies to manage nematode infections in livestock.

Abstract
Lipids are an amazingly diverse group of biomolecules with an array of biological functions including protecting and maintaining key properties and structure. Oxidative insult in the form of UV, hydrothermal, or other damage leads to compromised lipid function and can be linked to a wide range of consumer complaints. This proof-of-principle study applied and evaluated redox lipidomic approaches for the characterization and profiling of selected lipids and their oxidation products in human hair. It was observed that cholesterol and cholesterol derivatives regions appeared to be the most susceptible to oxidative damage and this leads to further experiments, including the systematic characterization of oxidative products, and correlation of modifications with damage protocol.

Abstract
PCBs are known as neurotoxic compounds. Part of this neurotoxicity could be due to an alteration of the expression of TH-regulated genes in brain. To identify such genes, brain protein extracts of hypo- and hyperthyroid as well as PCB-treated embryos were compared by fluorescent 2D-DIGE. In total, we observed 109 differentially expressed proteins, of which 17 differed with both PCB and hypo- or hyperthyroid treatment. It was found that the interaction of PCBs with the expression of TH-regulated genes is congener-specific and that both hyperthyroidism- and hypothyroidism-related effects occur.

Abstract
The pars intercerebralis-corpora cardiaca complex in insects is the functional equivalent of the vertebrate brain-pituitary axis. During the past few decades more than 40 neuropeptides have been isolated from the locust brain-corpus cardiacum complex. Tedious and time-consuming successive purification rounds of large tissue extracts were necessary to achieve the purification and sequencing of most of these signal molecules. Nowadays, the combination of nanoscale liquid chromatography and the very sensitive tandem mass spectrometry allows us to identify and sequence peptides in very low concentration directly from tissue extracts. In this manuscript, we review previous data on the peptidome analysis of the locust corpora cardiaca, with emphasis on AKH processing. In addition, we report the peptide profiling of a single corpus cardiacum from Locusta migratoria. 23 peptides were isolated and sequenced in a single nano-LC-MS/MS experiment, demonstrating the sensitivity and effectiveness of mass spectrometry in peptide research.

Abstract
In the course of producing monoclonal antibodies to turkey prolactin, three monoclonal antibodies to turkey chromogranin A (CgA) were also produced, apparently arising from minor contamination of the turkey prolactin immunogen with peptide fragments of CgA. The identity of the antigen recognized by these antibodies was established by tandem mass spectrometry de novo sequencing of seven tryptic peptides from a turkey pituitary protein purified by immunoaffinity chromatography. These peptides showed high homology with distinctly separate regions of mammalian and ostrich CgA, and in silico cloned chicken CgA sequences. Chromogranin A immunostaining patterns on Western blots and pituitary tissue sections differed from those of prolactin, growth hormone, or luteinizing hormone (LH). Dual-label fluorescent immunohistochemistry revealed that CgA was co-localized with LH in most avian gonadotrophs in young chickens and turkeys, but not in adult, laying birds. Conversely, CgA was found in a majority of somatotrophs in laying birds but was absent from somatotrophs in young, growing chickens and turkeys. Lactotrophs contained no detectable CgA immunoreactivity in the tissues studied. These results suggest that CgA may modulate hormone secretion by gonadotrophs and somatotrophs in a manner that differs between cell type with age or reproductive state.

Abstract
Chromogranin B (CgB) is a regulated secretory protein that is stored in endocrine and neuroendocrine cells. It can be processed proteolytically to small peptide fragments. In the present study three proteolytic products of porcine CgB were obtained after size-exclusion, immunoaffinity, and reversed-phase chromatography, and then identified by electrospray tandem MS. One novel peptide was identified as S586-R602 (SR-17) and is phosphorylated at one or two serine residues. Another novel peptide H603-Q636 (HQ-34), with molecular mass 3815.56 Da, was found to be oxidized at the methionine residue. In addition, a secretolytin-like peptide fragment (KR-11), which is two amino acids shorter than the bovine secretolytin, was found. This is the first report that the C-terminal region of CgB, the homologue of human CCB, is proteolytically processed further into three small peptide fragments.
