Ltc1 is an ER-localized sterol transporter and a component of ER-mitochondria and ER-vacuole contacts.
Organelle contact sites perform fundamental functions in cells, including lipid and ion homeostasis, membrane dynamics, and signaling. Using a forward proteomics approach in yeast, we identified new ER-mitochondria and ER-vacuole contacts specified by an uncharacterized protein, Ylr072w. Ylr072w is a conserved protein with GRAM and VASt domains that selectively transports sterols and is thus termed Ltc1, for Lipid transfer at contact site 1. Ltc1 localized to ER-mitochondria and ER-vacuole contacts via the mitochondrial import receptors Tom70/71 and the vacuolar protein Vac8, respectively. At mitochondria, Ltc1 was required for cell viability in the absence of Mdm34, a subunit of the ER-mitochondria encounter structure. At vacuoles, Ltc1 was required for sterol-enriched membrane domain formation in response to stress. Increasing the proportion of Ltc1 at vacuoles was sufficient to induce sterol-enriched vacuolar domains without stress. Thus, our data support a model in which Ltc1 is a sterol-dependent regulator of organelle and cellular homeostasis via its dual localization to ER-mitochondria and ER-vacuole contact sites
“Mejoramiento de la educación médica en la Universidad Nacional de Cuyo”
La Universidad Nacional de Cuyo, después de un proceso de autoevaluación en 1994-95, realizó un cambio curricular muy importante en su carrera de medicina, que se inició en el ciclo lectivo 1997. Los principios que guiaron el nuevo diseño curricular fueron: Enfoque científico-antropológico-social, Integración, Significación, Flexibilización, Protagonismo en el aprendizaje y Evaluación continua. El curriculum incluye: Cursos Biomédicos intensivos, integrados por varias disciplinas y trabajado con la metodología de Aprendizaje Basado Sobre Problemas; Cursos Longitudinales de formación humanística; Rotaciones Clínicas intensivas y un año de Práctica Final Obligatoria en internación, atención ambulatoria y emergencias. La mayor parte del tiempo de clases se trabaja en grupos pequeños de alumnos y hasta en una relación docente/alumno = 1/1, sin haber aumentado la planta de personal docente. El Plan de Estudios incluye dos Pruebas Globales: una al finalizar el ciclo básico de tres años –sin aprobar la cual, el alumno no puede ingresar al ciclo clínico- y otra al finalizar el ciclo clínico, cuya aprobación es indispensable para obtener el diploma. El rendimiento de los alumnos en el nuevo curriculum es superior (diferencias altamente significativas) al que se observaba en el tradicional, dado que un muy alto porcentaje de alumnos comienza cada año de la carrera habiendo aprobado todas las asignaturas del año anterior. En marzo de 2003 han recibido su diploma de Médico los primeros 46 egresados del nuevo Plan de Estudios (37,40 % de los ingresantes en 1997). De los restantes, el 28,45 % rendirán la Prueba Global final el próximo octubre, cuando sumarán un 65,85 % los estudiantes graduados durante el año siguiente a la finalización teórica de la carrera. Estas cifras reducen el desgranamiento de la cohorte a un 34,15 % y mejoran por amplio margen las cifras de duración real de la carrera, desgranamiento y deserción, obtenidas durante la autoevaluación de 1994-95. Por otra parte, las Pruebas Globales son instancias integradoras, que evalúan las estructuras de conocimiento, trabajadas en redes, a través de la necesidad de recuperar la información y aplicarla a la solución de casos clínicos complejos. Además, la Prueba Global de Ciclo Clínico incluye una instancia oral estructurada con pacientes estandarizados, que evalúa las habilidades clínicas, actitudes y destrezas de los alumnos. De modo que estas pruebas son, además, garantía de calidad de los futuros médicos
Incidence and Predictors of Mortality among Preterm Neonates Admitted to the Neonatal Intensive Care Unit at Debre Markos Referral Hospital, Northwest Ethiopia.
Background: Prematurity is the most frequent cause of neonatal death and the second leading cause of under-five mortality. Preterm related complications accounts for 35 % of neonatal deaths within the first week after birth. So far, most studies done in Ethiopia have focused on estimating the prevalence and determinant factors of premature neonatal death. The current study aimed to assess the incidence and predictors of mortality among preterm neonates admitted to neonatal intensive care unit at Debre Markos Referral Hospital. Methods: An institution-based retrospective follow up study was conducted among premature neonates admitted to Neonatal Intensive Care Unit at Debre Markos Referral Hospital from July 2019 to October 2019. Around 498 patients were selected randomly. A multivariable cox proportional hazards model was fitted to identify predictors of mortality. Results: A total of 498 preterm babies were followed, and the mean age for follow up at the time of admission to NICU was 15 hours ± 38 SD. Death rate in preterm was estimated to be 27.11% (95% CI: 23.3%, 31.1%). Preterm neonates with gestational age of less than 32 weeks (AHR=1.51; 95% CI: 1.02, 2.24), respiratory distress syndrome (AHR=1.49; 95% CI: 1.03, 2.17), perinatal asphyxia (AHR=1.74, 95% CI: 1.01, 2.76) and congenital malformation (AHR=3.38, 95% CI: 1.21, 8.77) were statistically significant predictors of mortality among preterms. Conclusion: The incidence of death in preterm neonates is relatively low. Gestational age less than 32 weeks, perinatal asphyxia, respiratory distress syndrome and congenital malformation were found as predictors

Social Anxiety Disorder Among Undergraduate Students of Hawassa University, College of Medicine and Health Sciences, Ethiopia.
Introduction:Social anxiety disorder (SAD), also called social phobia, is an uncontrollable fear of social situations, which involve fear of observation or making contact with strangers. So, helping individuals with social anxiety, which is among the factors affecting mental health, can significantly influence a students' mental health and prevent other problems. Objective:The study aimed at assessing the magnitude of SAD and its determinants among undergraduate students of Hawassa University, College of Medicine and Health Sciences. Methods:An institution based cross-sectional study was conducted from April 1 to May 30, 2018, in Hawassa University, College of Medicine and Health Sciences. We selected participants by a stratified random sampling method, and we collected data independently from each stratum (department) using a 17 item self-rating Social Phobia Inventory (SPIN) scale to assess SAD. We performed multiple logistic regression analysis to find factors associated with SAD. Results:Out of 304 students, 293 completed the questionnaire, with a response rate of 96.3%. The mean age of the participants was 22.13 years with a standard deviation of ± 2.176, and 172 (58.7%) were males. The prevalence of SAD was 32.8%. Family history of mental illness (AOR=4.72, 95% CI (1.25, 17.74)), being a 3rd-year student (AOR=0.178, 95% CI (0.055, 0.57)) and being a 4th year student (AOR=0.15, 95% CI (0.049, 0.49)) were significantly associated with SAD. Conclusion:This study showed a high prevalence of SAD among medicine and health science students of Hawassa University. Therefore, the Ethiopian Ministry of Higher Education and university officials need to draw up a plan to reduce social phobia
Three hypothesis algorithm with occlusion reasoning for multiple people tracking
This work proposes a detection-based tracking algorithm able to locate and keep the identity of multiple
people, who may be occluded, in uncontrolled stationary environments. Our algorithm builds a tracking graph
that models spatio-temporal relationships among attributes of interacting people to predict and resolve partial
and total occlusions. When a total occlusion occurs, the algorithm generates various hypotheses about the
location of the occluded person considering three cases: (a) the person keeps the same direction and speed,
(b) the person follows the direction and speed of the occluder, and (c) the person remains motionless during
occlusion. By analyzing the graph, our algorithm can detect trajectories produced by false alarms and estimate
the location of missing or occluded people. Our algorithm performs acceptably under complex conditions, such
as partial visibility of individuals getting inside or outside the scene, continuous interactions and occlusions
among people, wrong or missing information on the detection of persons, as well as variation of the person’s
appearance due to illumination changes and background-clutter distracters. Our algorithm was evaluated on
test sequences in the field of intelligent surveillance achieving an overall precision of 93%. Results show
that our tracking algorithm outperforms even trajectory-based state-of-the-art algorithms
TECHNOLOGICAL ASPECTS OF RYE CULTIVATED IN THE CONDITIONS OF SANDY SOILS IN SOUTHERN OLTENIA
Rye (Secale cereale L.) is an important crop in Europe, where it occupies about 90% of the world's area cultivated with this cereal (FAOSTAT, 2018), mainly in the countries of Central and Eastern Europe. The main research highlights the mechanisms of adaptation of rye culture to climate change, aimed at identifying genotypes that have a good behavior in culture under conditions of abiotic (thermohydric) and biotic stress (pathogens and pests) in order of restoring the production capacity and protection of agroecosystems in the area of sandy soils by promoting in culture some genotypes tolerant to thermohydric stress. In the two experimented years of 2020 and 2021 the obtained results prove the new genotypes promoted on the market had a higher capacity of production than the Control (Suceveana variety), with an average yield of over 4555 kg/ha registered at Serafino genotype in the conditions of a sandy soil with a low natural fertility, poorly supplied with total nitrogen (0.05-0.07%). In average, during the tested years, the attack frequencies of pests manifested in the comparative rye culture, as well as the attack intensities did not show significant differences from one variety to another, significant differences compared to the control variety (Suceveana) being observed only in the case of Serafino variety.
AntVideoRecord: Autonomous system to capture the locomotor activity of leafcutter ants
The leafcutter ants (LCA) are considered plague in a great part of the American continent,
causing great damage in production fields. Knowing the locomotion and foraging rhythm in
LCA on a continuous basis would imply a significant advance for ecological studies, fundamentally
of animal behavior. However, studying the forage rhythm of LCA in the field
involves a significant human effort. This also adds a risk of subjective results due to the
operator fatigue. In this work a new development named ‘AntVideoRecord’ is proposed
to address this issue. This device is a low-cost autonomous system that records videos of
the LCA path in a fixed position. The device can be easily reproduced using the freely accessible
source code provided. The evaluation of this novel device was successful because it
has exceeded all the basic requirements in the field: record continuously for at least seven
days, withstand high and low temperatures, capture acceptable videos during the day and
night, and have a simple configuration protocol by mobile devices and laptops. It was possible
to confirm the correct operation of the device, being able to record more than 1900 h
in the field at different climate conditions and times of the day.
