Fruit peels as sources of bioactive compounds with antioxidant and antimicrobial properties

Recently, a major interest in searching for phytochemicals with nutritional and pharmaceutical purposes has arisen. In this regard, it is known that polyphenols present antioxidant properties as well as an inhibitory effect against some kinds of microorganisms. The aim of this study was to obtain aqueous-ethanolic extracts from peels of avocado, cocoa bean, coconut and cactus pear by ultrasound-assisted extraction. The extracts were characterized in terms of phenolics (Folin-Ciocalteu reagent), antioxidant potential (ferric reducing/antioxidant power assay), radical-scavenging ability (2,2-diphenyl-2-picrylhydrazyl free radical assay), and antimicrobial activity against Staphylococcus aureus, Shigella dysenteriae and Candida albicans (disk diffusion test). The results revealed that the avocado peel extract had the highest phenol content (36.5 mg EAG g-1 dry weight), the highest antioxidant activity (141.2 mME Trolox g-1 dry weight) and the lowest IC50 value (59 ppm). Furthermore, avocado and coconut peels demonstrated an inhibitory effect against the tested microorganisms. Highlights Bioactive compounds from fruit by-products were obtained by ultrasound-assisted extraction. A positive correlation between phenolics and antioxidant activity was observed. Extracts with higher antioxidant activity were more active against the tested microorganisms. Fruit by-products could represent an important source of compounds with antioxidant and antimicrobial properties.Recently, a major interest in searching for phytochemicals with nutritional and pharmaceutical purposes has arisen.

A whole genome duplication drives the genome evolution of Phytophthora betacei, a closely related species to Phytophthora infestans

BACKGROUND: Pathogens of the genus Phytophthora are the etiological agents of many devastating diseases in several high-value crops and forestry species such as potato, tomato, cocoa, and oak, among many others. Phytophthora betacei is a recently described species that causes late blight almost exclusively in tree tomatoes, and it is closely related to Phytophthora infestans that causes the disease in potato crops and other Solanaceae. This study reports the assembly and annotation of the genomes of P. betacei P8084, the first of its species, and P. infestans RC1-10, a Colombian strain from the EC-1 lineage, using long-read SMRT sequencing technology. RESULTS: Our results show that P. betacei has the largest sequenced genome size of the Phytophthora genus so far with 270 Mb. A moderate transposable element invasion and a whole genome duplication likely explain its genome size expansion when compared to P. infestans, whereas P. infestans RC1-10 has expanded its genome under the activity of transposable elements. The high diversity and abundance (in terms of copy number) of classified and unclassified transposable elements in P. infestans RC1-10 relative to P. betacei bears testimony of the power of long-read technologies to discover novel repetitive elements in the genomes of organisms. Our data also provides support for the phylogenetic placement of P. betacei as a standalone species and as a sister group of P. infestans. Finally, we found no evidence to support the idea that the genome of P. betacei P8084 follows the same gene-dense/gense-sparse architecture proposed for P. infestans and other filamentous plant pathogens. CONCLUSIONS: This study provides the first genome-wide picture of P. betacei and expands the genomic resources available for P. infestans. This is a contribution towards the understanding of the genome biology and evolutionary history of Phytophthora species belonging to the subclade 1c

A pilot study applying the plant Anchored Hybrid Enrichment method to New World sages (Salvia subgenus Calosphace; Lamiaceae)

We conducted a pilot study using Anchored Hybrid Enrichment to resolve relationships among a mostly Neotropical sage lineage that may have undergone a recent evolutionary radiation. Conventional markers (ITS, trnL-trnF and trnH-psbA) have not been able to resolve the relationships among species nor within portions of the backbone of the lineage. We sampled 12 representative species of subgenus Calosphace and included one species of Salvia´s s.l. closest relative, Lepechinia, as outgroup. Hybrid enrichment and sequencing were successful, yielding 448 alignments of individual loci with an average length of 704. bp. The performance of the phylogenomic data in phylogenetic reconstruction was superior to that of conventional markers, increasing both support and resolution. Because the captured loci vary in the amount of net phylogenetic informativeness at different phylogenetic depths, these data are promising in phylogenetic reconstruction of this group and likely other lineages within Lamiales. However, special attention should be placed on the amount of phylogenetic noise that the data could potentially contain. A prior exploration step using phylogenetic informativeness profiles to detect loci with sites with disproportionately high substitution rates (showing "phantom" spikes) and, if required, the ensuing filtering of the problematic data is recommended. In our dataset, filtering resulted in increased support and resolution for the shallow nodes in maximum likelihood phylogenetic trees resulting from concatenated analyses of all the loci. Additionally, it is expected that an increase in sampling (loci and taxa) will aid in resolving weakly supported, short deep internal branches.Fil: Fragoso Martínez, Itzi.

Orthotopic Ileal Neobladder Reconstruction for Bladder Cancer: Is Adjuvant Chemotherapy Safe?

ABSTRACT Objective: We examined our database of patients undergoing radical cystectomy (RC) with orthotopic neobladder (NB) to determine whether adjuvant chemotherapy in this group is safe. Materials and Methods: We performed a retrospective analysis of patients who underwent radical cystectomy and urinary diversion between 1992 and 2004. Relevant clinical and therapeutic data were entered into a database. High-risk bladder cancer patients who underwent NB were identified. They were stratified into 2 groups, those who received adjuvant chemotherapy and those who did not. The incidence of complications between the 2 groups was analyzed and compared. Results: Over the 12-year period, 136 patients underwent RC and NB construction for bladder cancer. Of these, 83 patients were at high risk for recurrence. Nineteen patients received adjuvant chemotherapy and 64 did not. The complication rate in the adjuvant chemotherapy group was 53% and it was 23% in those who did not receive chemotherapy. There were no perioperative or treatment related death. There were 2 patients with grade 4 toxicity in the adjuvant chemotherapy group. There was a statistical difference between these two groups with regard to the incidence of complications. However, none of these complications was life-threatening, required only conservative treatment and caused no long-term disability. Conclusions: Adjuvant chemotherapy is a safe treatment for patients undergoing RC and NB substitution. Hence, the option of orthotopic NB should not be denied in selected bladder cancer patients with high risk for recurrent disease

Caloric reductions needed to achieve obesity goals in Mexico for 2030 and 2040: A modeling study

Background In Mexico, obesity prevalence among adults increased from 23% in 2000 to 36% in 2018, approximately. Mexico has not defined short- or long-term obesity goals, obscuring the level of effort required to achieve a relevant impact. We aimed to explore potential obesity goals for 2030 and 2040 in Mexico and to estimate the required caloric reductions to achieve them. Methods and findings We obtained anthropometric and demographic information on the Mexican adult population (age ≥20 years) from the Health and Nutrition Surveys conducted in 2000, 2006, 2012, 2016, and 2018 (n = 137,907). Each survey wave is cross-sectional, multistage, and representative of the Mexican population at the national, regional, and urban/rural levels. Obesity prevalence was projected for 2030 and 2040 by combining population projections of energy intake by socioeconomic status (SES) with a weight-change microsimulation model taking into account individual-level information on sex, age, physical activity, and initial body weight and height. If current trends continue, Mexico’s obesity prevalence is expected to increase from 36% (95% CI 35% to 37%) in 2018 to 45% (uncertainty interval [UI] 41% to 48%) in 2030 and to 48% (UI 41% to 55%) in 2040. Based on expert opinion, we identified 3 obesity goals scenarios: (1) plausible (38% in 2030 and 36% in 2040); (2) intermediate (33% in 2030 and 29% in 2040); and (3) ideal based on the average prevalence of Organization for Economic Co-operation and Development countries (OECD; 19%). We estimated the caloric reductions needed to achieve the goal scenarios using the microsimulation model. Obesity was projected to increase more rapidly in the low SES (around 34% in 2018 to 48% (UI 41% to 55%) in 2040), than in the middle (around 38% to 52% (UI 45% to 56%)), or high SES group (around 36% to 45% (UI 36% to 54%)). Caloric reductions of 40 (UI 13 to 60), 75 (UI 49 to 95), and 190 (UI 163 to 215) kcal/person/day would be needed to reach the plausible, intermediate, and the ideal (OECD) average scenarios for 2030, respectively. To reach the 2040 goals, caloric reductions of 74 (UI 28 to 114), 124 (UI 78 to 169), and 209 (UI 163 to 254) kcal/person/day would be required, respectively. Study limitations include assuming a constant and sedentary physical activity level, not considering cohort-specific differences that could occur in the future, and assuming the same caloric trends under no intervention and the obesity goal scenarios. Conclusions To reach the 3 obesity goals in 2040, caloric reductions between 74 and 209 kcal/day/person would be needed in Mexico. A package of new and stronger interventions should be added to existing efforts such as food taxes and warning labels on non-nutritious food

El Sistema de Mercado de Cacao en El Salvador: Oportunidades para apoyar la renovación y la rehabilitación

El proyecto Maximizando las Oportunidades en Café y Cacao en las Américas (MOCCA) es una iniciativa del Departamento de Agricultura de los Estados Unidos (USDA) e implementado por el consorcio liderado por TechnoServe, en colaboración con Lutheran World Relief, Initiative for Smallholder Finance, y World Coffee Research. Esta iniciativa regional aplicará un enfoque de sistemas de mercado para mejorar los medios de vida de 120,000 agricultores en los sectores de café y cacao en Ecuador, El Salvador, Guatemala, Honduras, Nicaragua y Perú (en adelante, referidos como países MOCCA) a través de una mayor productividad y comercio. Dada la complejidad del diseño del proyecto MOCCA, la evaluación de impacto evaluará los resultados a dos niveles: 1) a nivel del sistema de mercado para evaluar los cambios en el comportamiento de los actores clave del sistema de mercado, y 2) a nivel del agricultor para evaluar los cambios en los beneficios proporcionados a los agricultores dentro del sistema de mercado. Este reporte describe los resultados de la primera parte de la evaluación de línea de base a nivel de sistemas de mercado, que será utilizada por el equipo de MOCCA para informar la estrategia del programa. Esta evaluación utilizó métodos cualitativos, incluyendo entrevistas semiestructuradas y grupos focales con actores ubicados en diferentes posiciones dentro del sector, para construir una imagen sólida de cómo funciona actualmente cada sistema a nivel nacional. La atención se centró en identificar a los actores presentes y comprender su comportamiento actual dentro del sistema frente a otros actores y ante los agricultores. Siguiendo la Teoría del Cambio de MOCCA, el estudio se centró en los comportamientos relacionados con la provisión de servicios a los agricultores, incluida la asistencia técnica, el material genético, la investigación y las finanzas, con especial énfasis en estos servicios en relación con procesos de rehabilitación y renovación (R&R). Trescientos actores participaron como informantes en los once sectores estudiados (5 países para café, 6 países para cacao). Los datos fueron recolectados entre abril y junio de 2019. Este reporte describe el sistema de mercado de CACAO en EL SALVADOR en el momento de la investigación

The Cacao Market System in Honduras: Opportunities for Supporting Renovation and Rehabilitation

The Maximizing Opportunities in Coffee and Cacao in the Americas (MOCCA) project is a five-year initiative funded by the United States Department of Agriculture (USDA) and implemented by a consortium led by TechnoServe, in collaboration with Lutheran World Relief, the Initiative for Smallholder Finance, and World Coffee Research. This regional initiative will apply a market systems approach to improve the livelihoods of 120,000 farmers in the coffee and cocoa sectors in Ecuador, El Salvador, Guatemala, Honduras, Nicaragua and Peru (henceforth MOCCA countries) through increased productivity and trade. Given the complexity of MOCCA’s design, the impact evaluation will evaluate outcomes at two levels - 1) at the market system level to assess changes in the behavior of key market system actors and 2) at the farmer level to assess changes in the benefits provided to farmers within the market system. This report is an extract from the results of the first part of the baseline evaluation, at the market systems level, which will be used by the MOCCA team to inform the Program's strategy. This assessment used qualitative methods, including semi-structured interviews and focus groups with actors from different positions within the sector in order to build a robust image of how each system is currently functioning at the national level. The focus was on identifying current actors and understanding their current behavior within the system vis-a-vis other actors, and vis-a-vis farmers. Following MOCCA’s Theory of Change, we focused on behaviors related to provision of services to farmers including technical assistance, genetic material, finance and research, with particular emphasis on these services as they relate to rehabilitation and renovation (R&R). Three hundred different actors were engaged as informants across the eleven sectors studied (5 countries for coffee, 6 countries for cacao). Data was collected during April to June 2019.
