Feasibility of Enzymatic Protein Extraction from a Dehydrated Fish Biomass Obtained from Unsorted Canned Yellowfin Tuna Side Streams: Part II.

The enzymatic extraction of proteins from fish biomasses is being widely investigated. However, little or almost no research has paid attention to the exploitation of unsorted fishery biomasses. This work is part of a larger study, Part I of which has already been published, and focuses on an extensive characterization of two collagenous samples, namely gelatin (G) and hydrolyzed gelatin peptides (HGPs), extracted from a dehydrated fish biomass coming from unsorted canned yellowfin tuna side streams.

Bio-Based Packaging: Materials, Modifications, Industrial Applications and Sustainability.

Environmental impacts and consumer concerns have necessitated the study of bio-based materials as alternatives to petrochemicals for packaging applications. The purpose of this review is to summarize synthetic and non-synthetic materials feasible for packaging and textile applications, routes of upscaling, (industrial) applications, evaluation of sustainability, and end-of-life options. The outlined bio-based materials include polylactic acid, polyethylene furanoate, polybutylene succinate, and non-synthetically produced polymers such as polyhydrodyalkanoate, cellulose, starch, proteins, lipids, and waxes.

Ocular disorders in users of H2 antagonists and of omeprazole.

We have conducted a cohort study of users of omeprazole and H(2) antagonists in Italy to investigate whether the peroral use of these drugs may be associated with an increased incidence of ocular disorders leading to loss of vision. We have used the Sistema Informativo Sanitario Regionale (SISR database) in Friuli-Venezia-Giulia to identify all subjects who received at least one prescription for cimetidine, famotidine, niperotidine, nizatidine, omeprazole, ranitidine or roxatidine between 1 January 1991 and 31 December 1994. We have identified all hospital admissions for serious vascular or inflammatory ocular disorders following any such prescription, reviewed and validated all medical records.

Use of amoxicillin and amoxicillin-clavulanic acid and hospitalization for acute liver injury.

Increase of acute liver injury in patients taking amoxicillin-clavulanic acid (co-amoxiclav) as compared to those taking amoxicillin has been suggested. To further investigate the potential hepatotoxicity of the two drugs a historical cohort study was conducted in the Italian region of Friuli-Venezia Giulia. One hundred and eighteen potential cases of acute liver injury were identified through the regional hospital information system and medical records were reviewed for all of them.

Characteristics of users of inhaled long-acting beta 2-agonists in a southern European population.

We characterized the population of users of inhaled long-acting beta 2-agonists in the region of Friuli-Venezia Giulia, in Italy, and assessed changes in asthma treatment and control after initiating long-acting beta 2-agonists. All residents using formoterol or salmeterol between 1992 and 1996 were identified in the regional Health Databases. Utilization rates of asthma medications and hospitalization rates for asthma were computed for the year before and after the date of the first long-acting beta 2-agonist prescription.
