In this work, 31 native Peruvian chili peppers were evaluated for their agro-morphological characteristics and sensory attributes. The descriptive sensory analysis (DSA) was used to evaluate the 31 chili pepper samples based on their acid, bell pepper, sweet, tomato, apple, citrus, fruity, herbal, oregano and passion fruit attributes. The data obtained from the DSA enabled the grouping of these 31 chili peppers into six groups based on their different sensory attributes, such as fruity, bell pepper and herbal. The most abundant group (12 of the 31) had the bell pepper, apple, herbal, fruity and sweet attributes. Each group contained different species and different physical appearances, indicating that species or different forms of chili pepper do not define that sensory attribute. Considering the fact that Peruvian peppers are in high demand, the results achieved would be useful for grow...

The volatiles were characterised by headspace solid phase micro extraction (HS-SPME), gas chromatography mass spectrometry (GC-FID/MS). A total of 127 compounds were identified with terpenes, esters and hydrocarbons were the predominant volatile compounds. Principal component analysis (PCA) of the volatile compounds yielded 2 significant PC's, and the scatter plot generated between PC1 and PC2 successfully segregated the 50 chili pepper samples into 7 groups. Clusters of hydrocarbons, esters, terpenes, aldehyde and ketones formed the major determinants of the difference.

Purpose. The purpose of this study is to examine the impact of economic growth, trade openness and manufacturing on CO2 emissions in India. Design/methodology/approach. The study employed autoregressive distributive lag (ARDL) bounds test approach and uses CO2 emissions, trade, manufacturing and GDP per capita to examine the relationship using an annual time series data from World Development Indicators during 1971 to 2016. Findings. Results depict that there exists a long-run relationship between CO2 emissions and other variables. Trade openness significantly reduces CO2 emissions, whereas manufacturing and GDP have a significant and positive impact on CO2 in the long run. Research limitations/implications. The findings of the study contribute to the body of knowledge by providing new evidence on the relationship between developmental metrics and the environment. These findings are crit...

We explored the concentration patterns of the bioactive metabolite plumericin produced by Himatanthus tarapotensis (Apocynaceae) under different edaphic conditions and variations in rainfall intensity, as well as its potential role in the chemical defense against insect herbivores. Values of plumericin concentration from leaves were obtained by High-Performance Liquid Chromatography, and evaluated as a function of differences in soil types, variation of precipitation, and variation of the abundance of insect herbivores, using first a Repeated Measures Correlation (rmcorr) and then a Generalized Linear Mixed Model (GLMM) analysis. Plumericin concentration is highly variable among plants, but with a significantly higher concentration in plants growing on clay soil compared to that of the white-sand soil habitat (p < 0.001). Plumericin concentration is not affected by precipitation. The cat...

Purpose: Kaposi's sarcoma (KS) is a multifocal angioproliferative disease. In Peru, the implementation of the highly active antiretroviral treatment (HAART) program was in 2005, the model for treating patients with HIV-positive KS shifted to a potential cure. In this study, we aim to compare clinicopathological characteristics and prognostic factors associated with outcomes in patients with HIV-positive KS. Methods: We developed a retrospective cohort study that includes patients with HIV/AIDS and KS seen in the Instituto Nacional de Enfermedades Neoplasicas between 1987 and 2017. Patients were divided into two groups according to the implementation of HAART in our country: the non-HAART group and those treated with HAART after 2005. Multivariate analysis for overall survival (OS) was performed with the Cox proportional hazard regression model. Results: There was a greater visceral compr...

Las Plantas de Tratamiento de Aguas Residuales (PTAR) son ambientes ideales para la recombinación de genes de resistencia a antibióticos (GRA) entre bacterias: colectan heces de miles de personas y las mezclan bajo condiciones que promueven el crecimiento bacteriano para convertir materia orgánica en inorgánica, usualmente en presencia de antibióticos de uso clínico y veterinario. Las aguas tratadas son descargadas en ríos y océanos o utilizados para la irrigación de cultivos y áreas verdes en la ciudad, promoviendo la reintroducción de bacterias resistentes y GRAs en el ambiente y en poblaciones humanas. Es así como los microbiomas de aguas residuales se convierten en potenciales reservorios de GRAs disponibles para patógenos humanos. Entre 2013 y 2015, realizamos muestreos mensuales de aguas pre y post-tratamiento de una PTAR de Lima que procesa residuos de casi un millón...

Background: The COVID‐19 outbreak has resulted in collision between patients infected with SARS‐CoV‐2 and those with cancer on different fronts. Patients with cancer have been impacted by deferral, modification, and even cessation of therapy. Adaptive measures to minimize hospital exposure, following the precautionary principle, have been proposed for cancer care during COVID‐19 era. We present here a consensus on prioritizing recommendations across the continuum of sarcoma patient care. Material and Methods: A total of 125 recommendations were proposed in soft‐tissue, bone, and visceral sarcoma care. Recommendations were assigned as higher or lower priority if they cannot or can be postponed at least 2–3 months, respectively. The consensus level for each recommendation was classified as “strongly recommended” (SR) if more than 90% of experts agreed, “recommended” (R)...

Bone sarcoma are infrequent diseases, representing < 0.2% of all adult neoplasms. A multidisciplinary management within reference centers for sarcoma, with discussion of the diagnostic and therapeutic strategies within an expert multidisciplinary tumour board, is essential for these patients, given its heterogeneity and low frequency. This approach leads to an improvement in patient's outcome, as demonstrated in several studies. The Sarcoma European Latin-American Network (SELNET), aims to improve clinical outcome in sarcoma care, with a special focus in Latin-American countries. These Clinical Practice Guidelines (CPG) have been developed and agreed by a multidisciplinary expert group (including medical and radiation oncologist, surgical oncologist, orthopaedic surgeons, radiologist, pathologist, molecular biologist and representatives of patients advocacy groups) of the SELNET consorti...

Soft tissue sarcoma (STS) and gastrointestinal tumors (GIST) encompass > 80 different histologic subtypes. Clinical practice guidelines for STS and GIST still lack in Latin-American countries. Tailored clinical guidelines are instrumental to improve outcome in sarcoma patients in LatinAmerican countries. This is the first review establishing STS and GIST guidelines for the purpose of LatinAmerican clinical practices to our knowledge.
