Despite increasing interest in the role played by global South receiving organizations of development volunteers, their agency and efforts are rarely investigated in detail. Our qualitative study explores the involvement of receiving partners in international volunteering spaces, using the German Weltwärts programme in Mexico as an example. By applying decolonial theory, and politics and ethics of care lens to our data, we explore how these organizations are ‘weaving’ a dense assistance and safety web around the volunteers. Such assistance is usually not monetized and mainly invisible in the discussion of volunteering for development. Our findings challenge the development discourse and the positionality of northern volunteers within the development architecture.

The pathogenesis of obesity and dyslipidemia involves genetic factors, such as polymorphisms related to lipid metabolism alterations predisposing their development. This study aimed to evaluate the effect of a nutrigenetic intervention on the blood lipid levels, body composition, and inflammation markers of adults with obesity and overweight. Eleven genetic variants associated with dyslipidemias in Mexicans were selected, and specific nutrigenetic recommendations for these polymorphisms were found. One hundred and one adults were recruited and assigned to follow either a standard or nutrigenetic diet for eight weeks. Anthropometric, biochemical, body composition, and inflammation markers were evaluated through standardized methods. Weighted genetic risk scores (wGRSs) were computed using the study polymorphisms. After intervention, both diets significantly decreased the anthropometric parameters and body composition (p < 0.05). Only the nutrigenetic diet group showed significant reductions in VLDL-c (p = 0.001), triglycerides (p = 0.002), TG:HDL (p = 0.002), IL-6 (p = 0.002), and TNF-α (p = 0.04). wGRSs had a high impact on the ΔTGs and ΔVLDL-c of both groups (standard diet: ΔTGs: Adj R2 = 0.69, p = 0.03; ΔVLDL-c: Adj R2 = 0.71, p = 0.02; nutrigenetic diet: ΔTGs: Adj R2 = 0.49, p = 0.03 and ΔVLDL-c: R2 = 0.29, p = 0.04). This nutrigenetic intervention improved lipid abnormalities in patients with excessive body weight. Hence, nutrigenetic strategies could be coadjuvant tools and enhance the standard dietary treatment for cardiometabolic diseases.

El artículo aborda el sentido de la precariedad del trabajo, especialmente del femenino, dadas las condiciones mercantiles de valorar la productividad. En especial, se aborda la precarización de los trabajos doméstico y extradoméstico (referido a la población económicamente activa), resultantes del proceso de liberalización económica.

Kuautlan (2021) es una videoinstalación performática de Patricia Henríquez realizada en condiciones de aislamiento debido a la pandemia del Covid-19 y transmitida en vivo por el Museo Universitario del Chopo como cierre del proyectoMalinche, Malinches 2020/2021 de La máquina del teatro. La acción de la artista consistió en una intervención plástica sobre la proyección de un archivo audiovisual integrado por cientos de testimonios de mujeres que construían una biografía colectiva. El presente ensayo se deriva de una experiencia situada en la recepción diferida del acontecimiento que se pregunta, a la luz de los aportes de Fischer-Lichte, si la pieza de Henríquez puede ser considerada performática a pesar de su virtualidad.

Dyslipidemias are known risk factors for chronic diseases. Precision nutrition interventions are designed according to characteristics, such as diet, phenotype, and genotype. This systematic review aimed to define a panel of genetic variants associated with lipid abnormalities that could be later used in nutrigenetic intervention studies. A systematic review was conducted following the PRISMA-P. Studies published from January 2010 to December 2020 in English language and humans were included from PubMed and ScienceDirect databases. Articles that demonstrated a strong association between polymorphisms (single nucleotide variation) of genes involved in lipid metabolism and increased risk for dyslipidemia were included. A total of 3031 articles were screened, but only 51 articles fulfilled the inclusion criteria. The genes included were FABP2, MTTP related to CM synthesis and secretion; LPL, LIPC involved in triglyceride hydrolysis; CETP, APOA1, LCAT, ABCA1, and APOA5 related to lipoprotein metabolism and APOE, LDLR, SCARB1, APOC3 involved in lipid clearance. In this systematic review, genetic variants related to chylomicron synthesis, triglyceride hydrolysis, lipoprotein metabolism, and lipid clearance demonstrated a strong association with lipid abnormalities, which can be used to design precision nutrition interventions that may help to prevent and treat dyslipidemia effectively.

Land subsidence in the Aguascalientes Valley, documented since the 1980s, has developed a large number of discontinuities that damage infrastructure. There is currently no methodology to accurately predict the site and time at which a discontinuity will occur, making it difficult to make decisions in urban planning or risk management. However, it is possible to determine the susceptibility of an area to the generation of fractures based on the factors associated with their formation. This study presents a zoning method based on the ground failure susceptibility index (GFSI) in the city of Aguascalientes, using the frequency ratio (FR) method and employing the depth of the basement, the subsidence rate, the subsidence gradient, and the groundwater level drawdown as variables. The zoning method included three categories of land subsidence susceptibility to fracturing, moderate, high, and very high, which were divided using the first (3.76) and second (4.24) quartiles of the GFSI. The zoning method was created with the discontinuities reported in 2010 and was validated with data from 2022. The results obtained show that 11.19% of the discontinuities developed between 2010 and 2022 were located in a zone of moderate susceptibility, 41.97% were located in a zone of high susceptibility, and 46.87% were located in a zone classified as having very high susceptibility.

It is often read that industrial microalgal biotechnology could contribute to carbon capture through photosynthesis. While technically accurate, this claim is rarely supported by sound figures nor put in regard to the carbon emissions associated with said processes. In this view, this work provides a quantitative assessment of the extent microalgal processes compensation for their carbon dioxide emissions. To do so, microalgae were cultivated under photolimited conditions. Their growth dynamic and photosynthetic apparatus status were monitored by daily cell density measurement and fluorescence assays. Ultimate analyses were used to determine microalgal carbon content. Simultaneously, the power consumption of the process was recorded, and the associated carbon dioxide emissions were computed using European electrical production carbon intensity. All in all, the recorded values confirmed microalgae growth under good physiological conditions and allowed computing the carbon capture rate, the energy storing rate, and the carbon dioxide emissions of the process. The process captured 0.72 ± 0.19 gCO2/day while emitting 182 gCO2/day, on average (over 15 days). The photoconversion efficiency was 4.34 ± 0.68%. Even if it were highly optimized (red/blue LED instead of white, for example), the process could only capture 1.02 ± 0.40% of its emissions. From these figures, the claim stating that a biotechnological microalgal production process could partly compensate for its emission seems rather bold. Authors should, therefore, emphasize other ecosystemic benefits of microalgal cultivation, such as phosphorous intake. Finally, we were also able to evaluate Chlorella vulgaris light and dark respiration (0.0388 ± 0.00179 day−1 and 7.42 × 10−3 ± 3.33 × 10−3 day−1), which could help to assess carbon emission by biomass respiratory activity.

Las mujeres en contexto de movilidad humana por la ruta Centro-Norte del Occidente de México es un perfil migratorio del que se tiene poca visibilidad. Las causas y motivaciones para salir del lugar de origen, al igual que las preocupaciones, dinámicas, necesidades y responsabilidades al momento de realizar el trayecto hacia Estados Unidos son muy diferentes a las de los hombres. Por ello, el presente recoge los principales hallazgos tras el análisis de la base de datos de la investigación “Movilidad humana por la ruta Centro - Norte del Occidente de México: Vulnerabilidades, alternativas y políticas públicas” desde las causas de salida y las vivencias de los trayectos vividos por las mujeres que fueron entrevistadas durante el trabajo de campo en cinco estados de la ruta Guanajuato, Jalisco, Nayarit, Sonora y Baja California.

<strong>Background:</strong> There has been increased interest in identifying the associated factors to Type 2 Diabetes Mellitus (T2DM) remission after bariatric surgery. One of these factors is the BP limb length. The objective of our study was to evaluate the T2DM remission rate in patients subjected to Roux -en- Y gastric bypass (RYGB) who had different Biliopancreatic (BP) limbs length. <strong>Methods: </strong>48 patients with obesity grade II, and T2DM diagnosis, were subjected to RYGB and completed a one year of surgical follow up. All patients were grouped according to the BP limb length: In group A (n= 24) patients with BP limbs of 100 cm or less; in group B (n= 24) patients with BP limb from 150 to 170 cm in length. <strong>Results: </strong>Both groups presented an elevated remission rate of T2DM (83% full remission in the population studied). In group A 18 patients (75%) presented a full remission, while 2 patients (8.3%) showed a partial remission and only 4 patients (16.7%) were considered without remission at the one year follow up. In group B all patients had some remission: 22 patients (91.7%) presented a full remission (91.7%) and the rest of the patients showed a partial remission (8.3%), no significant difference was found between the two groups. <strong> </strong> <strong>Conclusions:</strong> Bariatric surgery remains as the best long term treatment for obesity and its comorbidities, despite some differences in the RYGB technique, BP limb length from 50 to 170 cm did not affect post RYGB glycemic control.
