title: The preservation effect and mechanism of gelatin on golden pompano (Trachinotus blochii) fillets during cold storage

description: Abstract The effect of different concentrations of gelatin (0%, 2.5%, and 5%) and vacuum packaged on the preservation of golden pompano (Trachinotus blochii) fillets stored at 4 °C was studied over 14 days. The results suggested that both the gelatin groups (2.5% and 5%) showed a reduction in deterioration of colour, drip loss and texture compared to the control group (0%). In addition, the gelatin coating caused a slower reduction in the freshness indexes of the fish, such as total volatile base nitrogen (TVB-N), thiobarbituric acid reactive substances (TBARS), total viable counts and pH. During a certain storage period, the gelatin notably prevented the deterioration of the golden pompano fillet at 4 °C. The 5% gelatin group showed the best effect on preserving the freshness indexes. Thus, the application of gelatin as a preservative is highly prospective for the preservation of fish fillets.

title: Agricultural Productivity and Efficiency in the Portuguese Speaking African Countries (PALOP) and East-Timor

description: Abstract The Portuguese-Speaking African Countries (Palop) and East Timor are countries in the early stages of development with a strong presence of agricultural sector in their economies. The objective of this study is to investigate the agricultural productivity and efficiency of these countries. The Stochastic Frontier procedure was used to estimate the agricultural production frontier for Palop and East Timor, from which the Malmquist Total Factor Productivity Index (IPTF) was determined. In the Palop and East Timor, Total Agricultural Factor Productivity (TFP) is low against the technological availability in the sector worldwide. The dominance of small production makes efficiency the most important component of the sector’s performance in these countries.

title: Effect of storage on the bioactive compounds, nutritional composition and sensory acceptability of pitanga jams

description: Abstract Conventional and diet pitanga jams were prepared to assess the stability of bioactive compounds over 320 days of storage. The diet jam exhibited a higher nutritional value and bioactive compound content than the conventional jam. None of the tested jam formulations exhibited major changes in physical and nutritional characteristics during storage. However, the bioactive compound content and antioxidant activity were significantly reduced after processing pulp into jam and over the course of storage. Storage also had an effect on the sensory quality of the products. The conventional jam had higher flavour acceptance, whereas the diet jam exhibited lower scores for colour, appearance and overall acceptance.

title: ALKALINE PROTEASE PRODUCTION BY Bacillus licheniformis LBA 46 IN A BENCH REACTOR: EFFECT OF TEMPERATURE AND AGITATION

description: Abstract The production of protease from Bacillus licheniformis LBA 46 was studied in a 6 L reactor using the experimental design tool. The higher protease production was obtained in the exponential phase of growth reaching maximum activity (~3,000 U/mL) after 48 h of fermentation at 30 ºC and 300 rpm in a culture medium made of agroindustrial by-products. In the thermostability study, the semi-purified enzyme retained about 78% of the initial activity after 120 min at 50 ºC. The protease was purified 3.33 times by ammonium sulfate precipitation and DEAE-Sepharose column chromatography and had a molecular mass estimated at 40 kDa by SDS-PAGE. The purified protease showed optimum activity at 50 and 60 ºC, optimal activity in pH 8.5 and stability in the range between pH 5-10 after 24 h of incubation at 4 ºC, presenting more than 86% of the initial activity.

title: A prospective case series on surgical treatment of circumferential and semi-circumferential defects due to peri-implantitis

description: Abstract Different surgical treatment strategies for peri-implantitis with the use of graft material and membranes have been suggested without any longitudinal remarkable success rate. The present preliminary study was aimed to analyze a new clinical approach based on the disinfection of the implant connection, the disinfection of the implant surface and GBR approach in the treatment of circumferential and semi-circumferential bony defect resulting from peri-implantitis. Six consecutive patients were selected for the present study. After removal of factors that could potentially influence peri-implant pathology, the prosthetic rehabilitation was always removed and a full thickness flap was elevated to allow access to the peri-implant defect and the exposed implant surface. Once the defect was degranulated and the implant surface cleaned, a mixture (50:50) of autogenous bone and allograft was used. Guided bone regeneration technique using membranes was adopted and the flaps were closed for a submerged healing. Six months thereafter, a new re-opening procedure was performed and cleaned superstructures and crowns were repositioned. Patients were followed for one year thereafter and recalled for a customized oral hygiene every three months. Radiological and periodontal analysis was performed before surgery and every six months. The studied procedure was associated with a pronounced increase in REC and CAL with stable peri-implant conditions at 6 and 12 months. PI, BOP and PD values were significantly reduced both at 6 and 12 months. At 12 months, a mean PD gain of 4.5 mm and a bone loss reduction of 5.1 mm was obtained. Within the limitation of the present preliminary study, the proposed technique might represent a promising result for treatment of circumferential and semi-circumferential bone defects around implants affected by peri-implantitis.

title: Additive manufacturing of titanium alloy could modify the pathogenic microbial profile: an in vitro study

description: Abstract Additive manufacturing (AM) is an emerging process for biomaterials and medical devices. Direct Laser Metal Sintering (DLMS) is an AM technique used to fabricate Ti–6Al–4V implant materials with enhanced surface-related properties compared with wrought samples; thus, this technique could influence microbial adsorption and colonization. Therefore, this in vitro study was conducted to evaluate the impact of different implant production processes on microbial adhesion of periodontal pathogens. Titanium discs produced using two different processes—conventional and AM—were divided into three groups: conventional titanium discs with machined surface (G1), AM titanium discs with chemical treatment (G2) and AM titanium discs without chemical treatment (G3). Subgingival biofilm composed of 32 species was formed on the titanium discs, and positioned vertically in 96-well plates, for 7 days. The proportions of microbial complexes and the microbial profiles were analyzed using a DNA–DNA hybridization technique, and data were evaluated using Kruskal–Wallis and Dunnett tests (p &lt; 0.05). Lower proportions of the red complex species were observed in the biofilm formed in G2 compared with that in G1 (p &lt; 0.05). Moreover, the proportions of the microbial complexes were similar between G2 and G3 (p &gt; 0.05). Compared with G1, G2 showed reduced levels of Porphyromonas gingvalis , Actinomyces gerencseriae, and Streptococcus intermedius , and increased levels of Parvimonas micra , Actinomyces odontolyticus, and Eikenella corrodens (p &lt; 0.05). The microbial profile of G3 did not differ from G1 and G2 (p &gt; 0.05). The results of this in vitro study showed that titanium discs produced via AM could alter the microbial profile of the biofilm formed around them. Further clinical studies should be conducted to confirm these findings.

title: Does subgingival bacterial colonization differ between implants and teeth? A systematic review

description: Abstract The aim was of this study was to determine the current weight of evidence for the existence of specific differences between the microbiota of healthy teeth and healthy implants, or of teeth with periodontitis and implants with peri-implantitis. A systematic review was conducted according to the PRISMA statement. The MEDLINE, EMBASE and Cochrane databases were searched up to February 2018 for studies comparing microbiological data of biofilm samples collected from healthy teeth and implants or from teeth with periodontitis and implants with peri-implantitis. The weight of evidence was defined in three categories (strong, moderate and mild/some), according to the difference in number of studies showing statistically significantly higher counts and/or proportions and/or abundance and/or prevalence of microorganisms in health or in disease. Of the 132 articles identified, 8 were included. A wide range of microorganisms were present in different conditions but no microorganisms showed strong, moderate or mild/some evidence for a specific association with either teeth or implants. The results of this systematic review indicated that there is insufficient evidence in the literature to support specific differences between microorganisms colonizing teeth and implants, either in health or in disease.

title: Microbiological and clinical effects of adjunctive systemic metronidazole and amoxicillin in the non-surgical treatment of peri-implantitis: 1 year follow-up

description: Abstract The aim of this study was to evaluate the effects of adjunct systemic antibiotic treatment with metronidazole (MTZ) and amoxicillin (AMX) in patients receiving non-surgical subgingival debridement (NSD) for peri-implantitis. Forty subjects presenting with at least one implant with severe peri-implantitis were randomized into an experimental group [treated with NSD plus MTZ (400 mg) and AMX (500 mg) three times a day for 14 days] and a control group treated with NSD plus placebo. Clinical parameters and submucosal biofilm profiles were evaluated up to 1 year post-treatment. Overall, both treatments improved clinical parameters over time. At 1 year, mean probing depth (PD), mean clinical attachment (CA) level and proportions of red complex pathogens did not differ significantly between the two groups. In addition, mean PD and CA changes to 1-year posttreatment did not differ significantly between the two groups between baseline and 1-year post-treatment. These results suggest that the addition of MTZ and AMX to the treatment protocol of patients undergoing NSD for with severe peri-implantitis does not improve the clinical and microbiological outcomes of NSD. The fact that half of the implants in both groups did not achieve clinical success (PD &lt; 5 mm, no BoP, no bone loss) suggest that neither of the tested protocols were effective for treating severe peri-implantitis.

title: Accelerated Aging as a Vigor Test in Encholirium spectabile Seeds

description: ABSTRACT The objective was to verify how differences in the accelerated aging test, traditional method (water) or saturated NaCl solution influence the differentiation of the physiological potential of Encholirium spectabile seeds from two geographic regions of Brazil (Graça-CE and Serra Talhada-PE). The experimental design was completely randomized in a 2 × 2 × 5 factorial scheme, in which two methods (water and saturated NaCl solution), seeds from two geographic regions and five aging periods (0 h, 24 h, 48 h, 72 h and 96 h) were evaluated. Results indicated that seeds from Graça-CE were less vigorous than those from Serra Talhada-PE. However, both aging methods (water and saturated NaCl solution) increased the physiological potential of seeds harvested from Graça-CE. E. spectabile seeds presented different levels of physiological potential by the accelerated aging test.

title: Technical efficiency and technological heterogeneity in agriculture in the semi-arid and non-semi-arid regions of northeastern Brazil

description: Abstract This study aims to analyze the technological differences in agricultural production between the municipalities in the semiarid and non-semiarid Northeast Brazil. It uses the technological meta-frontier model proposed by Battese, Rao e O’Donnell (2004), and O’Donnell, Rao e Battese (2008), for responding to what extent these regional differences influence the efficiency of production. It was observed that the hypothesis that the municipalities belonging to the semiarid and non-semiarid face with different production opportunities. The results indicated, that comparing both regions, the non-semiarid region has the highest average technical efficiency with reference to meta-frontier.
