Abstract
The present paper describes the generation of derivatives from the hybrid peptide called Ent35-MccV, active against Gram-positive and Gram-negative bacteria. This peptide has a triple glycine hinge region between enterocin CRL35 and microcin V. In order to obtain variants of Ent35-MccV with greater biotechnological potential, a saturation mutagenesis was carried out in the hinge region. As a result, we obtained a bank of E. coli strains expressing different mutated hybrid bacteriocins in the central position of the hinge region. From all these variants, we found that the one bearing a tyrosine in the central region of the hinge (Ent35-GYG-MccV) is 2-fold more active against E. coli and 4-fold more active against Listeria than the original peptide Ent35-MccV. This derivative was purified and characterized. The development and evaluation of alternative hinges for Ent35-MccV represents a step forward in the bioengineering of antimicrobial peptides. This approach fosters the rational design of peptides with enhanced antimicrobial activity.

Abstract
This work aimed to study the opioid peptide β-casomorphin-7 (BCM7) degradation or stability during digestion using human gastrointestinal (GI) juices and porcine jejunal brush border membrane (BBM) peptidases. Synthetic BCM7 was subjected to in vitro digestion by GI fluids obtained from human volunteers for 180 min, and to downstream degradation with porcine BBM vesicles. The BCM7 was sampled at 4 time points over 24 h after BBM addition. The digests were profiled by HPLC-electrospray ionization mass spectrometry (ESI/MS) to monitor BCM7 during GI digestion, and intact BCM7 through BBM digestion was quantified by reverse-phase (RP)-HPLC. We found that BCM7 was partly digested with human GI enzymes, as 3 proteolytic fragments in addition to f(60-66) YPFPGPI were detected: f(62-66) FPGPI, f(60-65) YPFPGP and f(61-66) PFPGPI. The RP-HPLC analysis revealed that 42% of the initial peptide was degraded after only 2 h of BBM digestion, and as much as 79% was degraded after 4-h digestion with supplementation of BBM. In conclusion, this study showed that most of BCM7 was degraded during GI and BBM digestion, although a small amount (5%) was still detected after 24-h digestion. It remains to be studied whether the small amount of intact BCM7 detected after in vitro digestion is transported via active transceptors in the human intestinal epithelial cells and enters blood circulation.

Abstract
Prolonged exposure (>90 days) of bovine beta-lactoglobulin (BLG) to subdenaturing concentrations of either urea or potassium thiocyanate resulted in the formation of ordered polymers in the form of fibrils. The fibrils obtained with each chaotrope showed major differences in morphology, surface properties, thiol accessibility, and stability to dissociating agents as a consequence of the different chemical bonds involved in their stabilization. Hydrophobic interactions between BLG monomers are predominant in thiocyanate-formed fibrils, whereas urea-formed fibrils are stabilized by intermolecular disulfides generated through a thiol-disulfide exchange reaction. The different features of fibrils obtained with each chaotrope relate to the peculiar structural features and chemical properties of the "active" monomers generated by subdenaturing chaotrope concentrations in the early phases of the polymerization process, as detected by spectroscopic and limited proteolysis/mass spectrometry studies in the earliest stages of the action of individual chaotropes. The chaotrope-specific features of these early intermediates in turn affect the polymerization mechanism, whose intermediates were studied by size-exclusion chromatography on the soluble fraction at different times of fibril formation. The potential of these findings for the production of protein-derived nanostructures having different and controlled geometries and chemical properties is also discussed.

Abstract
There is a general agreement that the experimentally determined molecular weight (MW) of caseinomacropeptide (CMP) is greater than the theoretical MW. Some studies suggest that this is due to a pH-dependent aggregation of monomeric CMP. How this aggregation is influenced by pH is not understood. This study was carried out to study the nature of CMP aggregates and to clarify which conditions affect aggregation of CMP. The apparent MW of CMP at different pH values was determined using size-exclusion chromatography. Caseinomacropeptide was further characterized by immunochemical analysis, sodium dodecyl sulfate-PAGE, N-terminal sequencing, and mass spectrometry. The hydrophobicity of CMP was studied by means of 1-anilino-naphthalene-8-sulfonic acid binding experiments. Four CMP products prepared by different methods were studied: CMP produced by enzymatic (chymosin or pepsin) hydrolysis of kappa-casein (CN), and 2 commercial CMP products. Both commercial products and CMP resulting from chymosin-hydrolysis of kappa-CN (at pH 6.6) had elution volumes with a MW corresponding to 35 kDA at pH 8.0 and 3.4. Caseinomacropeptide prepared from pepsin-hydrolysis of kappa-CN (at pH 2.5) eluted as multiple peaks with apparent MW of 35, 18, and 9 kDa, again independently of pH. Hydrolysis of kappa-CN with chymosin or pepsin at different pH values (pH 2.5, 3.4, and 6.6) produced differently sized aggregates of CMP, largely depending on the pH of the hydrolysis. These results indicate that, whereas CMP molecules are irreversibly associated, CMP in kappa-CN may associate reversibly in a pH-dependent manner. We suggest that interactions between para-kappa-CN parts of the kappa-CN molecules may be a requisite for the pH-dependent dissociation/association.

Abstract
In traditional geriatric medicine, comprehensive assessment is considered crucial to the care of frail older patients. The principles of geriatric assessment--identifying high-risk patients and targeting them for preventive interventions--are also practiced by managed care organizations (MCOs). Self-reported health surveys and administrative data are two methods used by MCOs to identify members at high risk for adverse health outcomes and functional decline who may benefit from geriatric case management. For a successful partnership with primary care physicians, it is very important that geriatric care managers should be knowledgeable in the principles of geriatric medicine.
