Biological Field Expedition to the Ashaninka Communities of Coriteni Tarso (Rio Tambo) & Camantavishi (Rio Ene)

The expedition to the Ashaninka communities of Coriteni Tarso, Camantavishi and Shirampari in the summer of 2004 carried out a number of studies; primarily herpetological surveys but also vegetation, soil and hunting surveys. The work was carried out in little known areas where no previous systematic studies had been completed. The expedition recorded frogs and a snake not previously found in the department of Junín1. The expedition discovered at least one new species (to be registered as Cochranella parijarensis)

Calcium and mitochondrial metabolism in ceramide-induced cardiomyocyte death

AbstractCeramides are important intermediates in the biosynthesis and degradation of sphingolipids that regulate numerous cellular processes, including cell cycle progression, cell growth, differentiation and death. In cardiomyocytes, ceramides induce apoptosis by decreasing mitochondrial membrane potential and promoting cytochrome-c release. Ca2+ overload is a common feature of all types of cell death. The aim of this study was to determine the effect of ceramides on cytoplasmic Ca2+ levels, mitochondrial function and cardiomyocyte death. Our data show that C2-ceramide induces apoptosis and necrosis in cultured cardiomyocytes by a mechanism involving increased Ca2+ influx, mitochondrial network fragmentation and loss of the mitochondrial Ca2+ buffer capacity. These biochemical events increase cytosolic Ca2+ levels and trigger cardiomyocyte death via the activation of calpains

Functionality, physical activity, fatigue and quality of life in patients with acute COVID-19 and Long COVID infection

A prominent feature of COVID-19, both in the short and long term, is the reduction in quality of life (QoL) due to low functionality scores and the presence of fatigue, which can hinder daily activities. The main objective of this study is to compare the functional status, level of physical activity, fatigue, and QoL of patients with Long COVID to other COVID-19 patients who did not develop persistent illness, and to determine whether there is a relationship between these variables and QoL. A cross-sectional study was conducted with 170 participants who had been infected with COVID-19 or had developed Long COVID. The main variables studied were functionality, physical activity, QoL and fatigue, measured using the PostCOVID-19 Functional Status Scale (PCFS), International Physical Activity Questionnaire (IPAQ), Short Form 12 (SF-12), and Fatigue Severity Scale (FSS). The main findings show a significant relationship (p < 0.001) between reduced functionality, lower physical activity levels, increased fatigue severity, and poorer QoL in Long COVID patients. Furthermore, these variables are also related to worse QoL, but only functional status predicts it. In conclusion, our results have shown highly significant correlations between the group with COVID-19 and Long COVID regarding functional status, level of physical activity, QoL, and fatigue

Identificación de Hongos Micorrízicos en Plantaciones de Melina (Gmelina arborea Roxb) en el Trópico Húmedo Ecuatoriano

This study aimed to isolate and identify arbuscular mycorrhizal fungi in melina (Gmelina arborea Roxb) plantations. Two melina plantations of 1 and 3 years old located in the central zone of the humid Ecuadorian tropics, province of Los Ríos, Valencia were sampled. Soil and root samples were collected in the dry season between June and December 2015. The results showed the presence of the arbuscular mycorrhizal fungi genera Glomus and Gigaspora. The genus with the greatest representativeness in quantity of spores per gram of soil was Glomus. The highest percentage of mycorrhizal colonization occurred in the roots of 1-year-old trees.El objetivo de esta investigación fue aislar e identificar hongos formadores de micorriza arbuscular en plantaciones de melina (Gmelina arborea Roxb). Se muestrearon dos plantaciones de melina de 1 y 3 años de edad, ubicadas en la zona central del trópico húmedo ecuatoriano, provincia de Los Ríos, cantón Valencia. Las muestras de suelo y raíces se recolectaron en la época seca entre junio y diciembre de 2015. Los resultados mostraron la presencia de los géneros de hongos micorrízicos arbusculares Glomus y Gigaspora. El género con mayor representatividad en cantidad de esporas por gramo de suelo fue Glomus. El mayor porcentaje de colonización micorrízica se presentó en las raíces de los árboles de 1 año de edad

Safe Areas for the Placement of Standard Shoulder Arthroscopy Portals: An Anatomical Study

The abundant vascular structures that surround the shoulder joint are complex and variable, complicating arthroscopy approaches. The aim of this study is to determine safe and risky areas around standard posterior and standard anterior portals, and accounting for the distribution of neurovascular structures of small and medium diameters that can lead to intra-articular bleeding during surgery. The standard posterior portal, and standard anterior portal were placed as described in the literature, and punch dissection was performed 2.5 cm around the trocar in situ. The arrangement of each identified structure was photographically documented and digitalized for each anatomic plane; the distance to the trocar and the diameter of each structure were measured. Based on each digitalized anatomic plane, safe and risky tissue areas were determined, and a clock face coordinate system was used to represent these areas. The safe area around the standard posterior portal was located between 11 and 1 o´clock for the left shoulder and 11 and 2 o´clock for the right shoulder. For the standard anterior portal, the safe area was located between 2 and 3 o´clock for the left shoulder and between 9 and 12 o´clock for the right shoulder. However, we did document a risk of injuring the cephalic vein 5 times, the axillary artery 3 times and the deltoid branch of the thoracoacromial artery once. This study reports quantitatively the total number of small diameter structures present in the two shoulder arthroscopic portals evaluated. The safe areas proposed in this study must be evaluated to propose new access points for performing arthroscopic procedures on the shoulder

Integrative development of a short screening questionnaire of highly processed food consumption (sQ-HPF)

Background: Recent lifestyle changes include increased consumption of highly processed foods (HPF), which has been associated with an increased risk of non-communicable diseases (NCDs). However, nutritional information relies on the estimation of HPF consumption from food-frequency questionnaires (FFQ) that are not explicitly developed for this purpose. We aimed to develop a short screening questionnaire of HPF consumption (sQ-HPF) that integrates criteria from the existing food classification systems. Methods: Data from 4400 participants (48.1% female and 51.9% male, 64.9 +/- 4.9 years) of the Spanish PREDIMED-Plus (PREvention with MEDiterranean DIet) trial were used for this analysis. Items from the FFQ were classified according to four main food processing-based classification systems (NOVA, IARC, IFIC and UNC). Participants were classified into tertiles of HPF consumption according to each system. Using binomial logistic regression, food groups associated with agreement in the highest tertile for at least two classification systems were chosen as items for the questionnaire. ROC analysis was used to determine cut-off points for the frequency of consumption of each item, from which a score was calculated. Internal consistency of the questionnaire was assessed through exploratory factor analysis (EFA) and Cronbach's analysis, and agreement with the four classifications was assessed with weighted kappa coefficients. Results: Regression analysis identified 14 food groups (items) associated with high HPF consumption for at least two classification systems. EFA showed that items were representative contributors of a single underlying factor, the HPF dietary pattern (factor loadings around 0.2). We constructed a questionnaire asking about the frequency of consumption of those items. The threshold frequency of consumption was selected using ROC analysis. Comparison of the four classification systems and the sQ-HPF showed a fair to high agreement. Significant changes in lifestyle characteristics were detected across tertiles of the sQ-HPF score. Longitudinal changes in HPF consumption were also detected by the sQ-HPF, concordantly with existing classification systems. Conclusions: We developed a practical tool to measure HPF consumption, the sQ-HPF. This may be a valuable instrument to study its relationship with NCDs
