Escalamiento de producto en polvo con fórmula vegana para niños de 1 a 3 años

Como objetivo del PAP 4F04, programa para mejoramiento de la calidad, productividad y logistica en la industria regional, se realizaron estudios y pruebas piloto e industrial en apoyo al Organismo de Nutrición Infantil para lograr el escalamiento de una fórmula de leche en polvo, la cual fue diseñada por parte de alumnos PAP de ITESO en primavera del 2022, dicha fórmula fue diseñada para niños de 1 a 3 años los cuales padezcan de intolerancia a la lactosa o diabetes de tipo 1 (Farjado & Prado, 2022). Los objetivos por parte de este proyecto realizado en verano eran inicialmente llevar a cabo pruebas piloto a nivel laboratorio y nivel industrial donde fueran determinados los tiempos de mezclado óptimos para una futrua producción de fórmula ONI vegana. No obstante, debido a complicaciones con la obtención de materias primas requeridas para realizar dichas pruebas, se optó por diseñar una guía experimental donde se especificara a detalle el procedimiento para llevar a cabo el escalamiento de la fórmula vegana, buscando beneficiar a futuros alumnos PAP y a ONI para nuevos escalamientos de fórmulas en polvo.ITESO, A.C

Prótesis unicondílea de rodilla: Valoración clínica preliminar

Los pacientes afectados de artrosis unicompartimetal de rodilla pueden ser tratados con diferentes métodos quirúrgicos. Los más habituales son la osteonomía tibial en jóvenes y la prótesis total de rodilla en ancianos. Una alternativa que va adquiriendo adeptos es la prótesis unicondílea. Tras un período inicial de gran euforia se pasó a otro de escepticismo, dando los resultados. El propósito del presente estudio es evaluar un nuevo diseño de prótesis de rodilla unicondílea (Alpina, IQL) a corto plazo siguiendo criterios clínicos y de calidad de vida. Se revisan 13 pacientes intervenidos entre Junio de 2000 a Marzo del 2002. Siete eran varones y seis mujeres. La edad media fue de 65 años (r=55-72ª). En doce casos la etiología fue artrosis y en uno necrosis del cóndilo interno. La evaluación clínica se realizó mediante el cuestionario sobre la calidad de vida SF-12. Todos los pacientes consiguieron una flexión de 110º y extensión completa. Sólo un paciente presentó molestias leves.Patients who have unicompartimental knee osteoarthritis can be manager by different surgical techniques. Young people are usually treated by tibial osteotomy and elderly people by total knee replacement. Unicondylar knee prosthesis is becoming an attractive recognized alternative. After a period of enthusiastic regarding this technique, scepticism took place based on the clinical results. The aim of this study is to evaluate, in firs instance, a new knee unicondylar knee prosthesis design (Alpine, IQL) following clinical criteria and quality of life. Thirteen patients, managed in between June 2000 and March 2002, are reviewed. Seven were males and six females. The mean age was 65 years (range 55-77 years). Osteoarthritis was the aetiology in twelve cases and necrosis of the medial condyle in one patient. The clinical evaluation was based on quality of life through a questionnaire SF-12. All patients improved a knee flexion of 110º and a complete extension. Only one patient had slight pain and had some limitation

Reaction of inbred lines of habanero hot pepper (Capsicum chinense Jacq.) to inoculation of Fusarium oxysporum

Objective: To evaluate the reaction of five inbred lines of habanero pepper (Capsicum chinense Jacq.) To the inoculation of Fusarium oxisporum and to identify genotypes with possible levels of resistance to this pathogen. Design/methodology/approach: Samples of stems of chili plants with typical symptoms of vascular wilting disease were obtained, due to their morphological characteristics of mycelium and conidia at the microscopic level it was identified as Fusarium oxisporum. By immersion of roots, at a concentration of 1x106 conidia per ml, five inoculated lines of habanero pepper were inoculated, in addition to the serrano-type cultivar Criollo de Morelos 334 (CM-334). The percentage disease index and the Area Under the Disease Progress Curve (AUDPC) were estimated in a randomized complete block design, with three repetitions. Results: Significant differences (p?0.05) were observed for disease index and ABCPE in the evaluated genotypes, evidencing the existing difference in the genetic base of the genotypes and the resistance or susceptibility to Fusarium oxisporum. The cultivar CM-334, the Habanero 5 and Habanero 8 lines presented the lowest percentage of incidence of the disease (10, 20 and 30%, respectively) and ABCPE of 300, 560 and 880. In turn, the Habanero 9 and Habanero 6 lines presented the highest ABCPE values with 2220 and 2190, respectively. Limitations on study/implications: The disease resistance response in plants is complex and contains multiple interactions between genes, proteins, and metabolites. Findings/conclusions: The grouping of genotypes based on their reaction to Fusarium wilt disease facilitated the identification of resistant and susceptible lines, which can be considered in subsequent genetic improvement works for the cultivation of chili.Objective: To evaluate the reaction of five inbred lines of habanero pepper (Capsicum chinense Jacq.) to the inoculation of Fusarium oxisporum and to identify genotypes with possible levels of resistance to this pathogen.

Can robotic-based top-down rehabilitation therapies improve motor control in children with cerebral palsy? A perspective on the CPWalker project

[EN] Cerebral Palsy (CP) is one of the most severe disabilities in childhood, and it demands important costs in health, education, and social services. CP is caused by damage to or abnormalities inside the developing brain that disrupt the brain's ability to control movement and maintain posture. Furthermore, CP is often associated with sensory deficits, cognition impairments, communication and motor disabilities, behavior issues, seizure disorder, pain, and secondary musculoskeletal problems. According to the literature, motor modules are peripheral measurements related to automatic motor control. There is a lack of evidence of change in motor modules in children with CP when different treatment approaches have been evaluated. Thus, new strategies are needed to improve motor control in this population. Robotic-based therapies are emerging as an effective intervention for gait rehabilitation in motor disorders such as stroke, spinal cord injury, and CP. There is vast clinical evidence that neural plasticity is the central core of motor recovery and development, and on-going studies suggest that robot-mediated intensive therapy could be beneficial for improved functional recovery. However, current robotic strategies are focused on the peripheral neural system (PNS) facilitating the performance of repetitive movements (a bottom-up approach). Since CP affects primarily brain structures, both the PNS and the central nervous system (CNS) should to be integrated in a physical and cognitive rehabilitation therapy (a top-down approach). This paper discusses perspectives of the top-down approach based on a novel robot-assisted rehabilitative system. Accordingly, the CPWalker robotic platform was developed to support novel therapies for CP rehabilitation. This robotic platform (Smart Walker + exoskeleton) is controlled by a multimodal interface enabling the interaction of CP infants with robot-based therapies. The aim of these therapies is to improve the physical skills of infants with CP using a top-down approach, in which motor related brain activity is used to drive robotic physical rehabilitation therapies. Our hypothesis is that the CPWalker concept will promote motor learning and this improvement will lead to significant improvements in automatic motor control.Lerma Lara, S.; Martínez Caballero, I.; Bayón, C.; Del Castillo, M.; Serrano, I.; Raya, R.; Belda Lois, JM....

Dung beetles (Coleoptera: Scarabaeidae) in grazing lands of the Neotropics: A review of patterns and research trends of taxonomic and functional diversity, and functions

Dung beetles are one of the most representative groups of insects associated with livestock, as they take advantage of the manure of livestock for food and reproduction. They have been widely used as a bio-indicator group to evaluate their responses to land-use change and other environmental disturbances by analyzing species diversity at different spatial and temporal scales. However, the impacts of livestock management practices, forms, and history on dung beetle diversity are still poorly understood. This paper is an exhaustive and systematic review of the existing peer-reviewed and indexed literature on the taxonomic diversity (species richness and composition), functional diversity, and ecological functions of dung beetles from different provinces and biogeographic domains in tropical grazing lands of the Neotropics. We analyzed the timeline of the studies conducted so far, and we detected increasing literature produced mainly in South America. We included the most frequent objectives, tendencies, software, and statistical analyses. Given the significant heterogeneity of livestock landscapes in the Neotropics, the reviewed studies have conceptualized broadly what a pasture is, and the authors have used different descriptions of other grazing lands. Additionally, management data and livestock practices vary widely among studies, and management history is poorly described. In future research, it is relevant to include as much information as possible and the consequences of different livestock management practices on additional ecological attributes of dung beetle assemblages at different landscape scales (spatial and temporal) to predict how ecological processes change in Neotropical landscapes. Considering the importance of the data to be included in future work, we propose a collection format to unify the information collected in the field when conducting ecological studies in grazing lands. Moreover, we define a classification system to homogenize the features that distinguish the multiple tropical grazing lands reported in the literature. Preserving dung beetle diversity and associated ecological functions is urgent for maintaining ecosystem services in grazing lands. The challenge for research institutions is to continue filling gaps in knowledge to help those who work in transferring knowledge, to help ranchers exercise better options for more sustainable livestock farming, and to publish results for conservation decision-making

Characterization of Tajogaite volcanic plumes detected over the Iberian Peninsula from a set of satellite and ground-based remote sensing instrumentation

Three volcanic plumes were detected during the Tajogaite volcano eruptive activity (Canary Islands, Spain, September–December 2021) over the Iberian Peninsula. The spatiotemporal evolution of these events is characterised by combining passive satellite remote sensing and ground-based lidar and sun-photometer systems. The inversion algorithm GRASP is used with a suite of ground-based remote sensing instruments such as lidar/ ceilometer and sun-photometer from eight sites at different locations throughout the Iberian Peninsula. Satellite observations showed that the volcanic ash plumes remained nearby the Canary Islands covering a mean area of 120 ± 202 km2 during the whole period of eruptive activity and that sulphur dioxide plumes reached the Iberian Peninsula
