Omics approaches to explore the coffee fermentation microecosystem and its effects on cup quality.

The cultivation and postharvest processing of coffee constitute the basis of the subsistence and traditional culture for rural family-owned farms, as well as for the economic success of commercial enterprises in many coffee-producing countries worldwide. The quality of the final beverage is determined by a multitude of variables. A key post-harvest factor is the spontaneous fermentation of the coffee beans, conducted directly on the farm, to remove the mucilage that firmly adheres to the beans.

Metagenomic Analysis of Surface Waters and Wastewater in the Colombian Andean Highlands: Implications for Health and Disease.

Urban water bodies serve as critical reservoirs of microbial diversity, with major implications for public health and environmental quality. This study aimed to characterize the microbial diversity of surface waters and wastewater from the Pasto River in the Colombian Andean Highlands, offering insights that may support water quality monitoring efforts. Sampling was conducted at three river sites and one wastewater location.

High resolution mass spectrometry-based screening for the comprehensive investigation of organic micropollutants in surface water and wastewater from Pasto city, Colombian Andean highlands.

The complexity of the aquatic environment scenario, including the impact of urban wastewater, together with the huge number of potential hazardous compounds that may be present in waters, makes the comprehensive characterization of the samples an analytical challenge, particularly in relation to the presence of organic micropollutants (OMPs). Nowadays, the potential of high-resolution mass spectrometry (HRMS) for wide-scope screening in environmental samples is out of question. Considering the physicochemical characteristics of OMPs, the coupling of liquid (LC) and gas chromatography (GC) to HRMS is mandatory.

Mathematical model of interaction and Coliphages.

We propose a mathematical model based in ordinary differential equations between bacterial pathogen and Bacteriophages to describe the infection dynamics of these populations, for which we use a nonlinear function with an inhibitory effect. We study the stability of the model using the Lyapunov theory and the second additive compound matrix and perform a global sensitivity analysis to elucidate the most influential parameters in the model, besides we make a parameter estimation using growth data of bacteria in presence of Coliphages (bacteriophages that infect ) with different multiplicity of infection. We found a threshold that indicates whether the bacteriophage concentration will coexist with the bacterium (the coexistence equilibrium) or become extinct (phages extinction equilibrium), the first equilibrium is locally asymptotically stable while the other is globally asymptotically stable depending on the magnitude of this threshold.

Burden of disease of COVID-19 in the department of Nariño, Colombia, 2020-2021.

Objectives.: To estimate the burden of disease of COVID-19 in the department of Nariño, Colombia, based on the disability-adjusted life years (DALYs) between March 2020 and August 2021.

MS2 coliphage inactivation by Al/Fe PILC-activated Catalytic Wet Peroxide Oxidation: multiresponse statistical optimization.

The optimization of the Catalytic Wet Peroxide Oxidation (CWPO) assisted by an Al/Fe-pillared clay (Al/Fe-PILC) was assessed in the inactivation of the MS2 coliphage in the presence of a synthetic surrogate of natural organic matter (NOM). The simultaneous effect of two experimental factors (i) HO dose - (HO) (3.00-25.

[Family vulnerability index in the municipality of Pasto, Colombia, 2012].

This study's objective was to measure the vulnerability index of families in the municipality of Pasto, Colombia. In a sample of 270 families of all socioeconomic strata (239 urban and 31 rural), a confidential survey was conducted using the vulnerability index, consisting of five dimensions: demographic, social, economic, environmental, and geography, forecasting, and prevention. The families in strata 1 and 2 and the houses in the center, west, northwest, and northeast of the urban area showed high vulnerability, even higher than those in rural areas.

Cancer incidence and mortality in the municipality of Pasto, 1998 - 2007.

Introduction: In Colombia, information on cancer morbidity at the population level is limited. Incidence estimates for most regions are based on mortality data. To improve the validity of these estimates, it is necessary that other population-based cancer registries, as well as Cali, provide cancer risk information.
