The effect of hesperidin added to quail diets on blood gas, serum biochemistry and Hsp70 in heat stress

El objetivo de este estudio fue determinar los efectos del flavonoide, que es un producto de la producción de cítricos, sobre los parámetros sanguíneos y la concentración de HSP70 en codornices aplicado en condiciones termoneutrales y de estrés por calor. En este contexto, 160 codornices (Coturnix coturnix japonica, macho), de 6 semanas de edad y 150-200 g de peso vivo, se alojaron en jaulas durante 1 semana de ejercicio y 5 semanas de período de ensayo. El diseño del estudio constó de 4 grupos de 40 animales y 4 subgrupos con 10 animales en cada grupo. La agrupación se realizó en forma de 2x2. Los grupos termoneutrales (24 ± 0.1 °C) son NC (0 g de hesperidina/kg de alimento base) y NHES3 (3 g de hesperidina/kg de alimento base) y los grupos bajo estrés por calor (34 ± 0.1 °C) son HC (0 g de hesperidina/kg de alimento base) y HHES3 (3 g de hesperidina/kg de alimento base), y se generaron aleatoriamente. En el caso de estrés por calor, las concentraciones de pO2, pH, HCO3 y Cl disminuyeron en el grupo HHES3 en comparación con el grupo HC (P<0.05). La concentración de enzimas ALP mostró una disminución significativa en el grupo HHES3 en comparación con el grupo HC en la condición de estrés por calor. El nivel de proteínas de choque térmico (Hsp70) aumentó en el suero sanguíneo, tejidos del riñón, hígado y pecho en el grupo HC con estrés celular durante el estrés por calor; sin embargo, la concentración de Hsp70 disminuyó significativamente en el grupo HHES3. Como resultado, se encontraron efectos positivos de la suplementación con hesperidina en la dieta tanto en condiciones de estrés por calor como en termoneutrales.The aim of this study was to determine the effects of flavonoid, which is a product of citrus production, on blood parameters and HSP 70 concentration in quails applied at thermoneutral and heat stress. In this study, 160 quails (Coturnix coturnix japonica, male), 6 wk old and 150-200 g live weight, were housed in cages for 1 wk of exercise and 5 wk of trial period. The study design consists of 4 groups of 40 animals and 4 subgroups with 10 animals in each group. Thermoneutral (24 ± 0.1 o C) groups are NC (0 g hesperidin/kg basal feed) and NHES3 (3 g hesperidin /kg basal feed) and heat stress (34 ± 0.1 oC) groups are HC (0 g hesperidin/kg basal feed) and HHES3 (3 g hesperidin /kg basal feed) were randomly generated. In the case of heat stress, pO2, pH, HCO3, Cl concentrations decreased in the HHES3 group compared to the HC group (P<0.05). ALP enzyme concentration showed a significant decrease in the HHES3 group compared to the HC group in the heat stress condition. Heat shock protein (HSP70) protein level increased in blood serum, kidney, liver and thigh tissues in HC group with cellular stress during heat stress; however, HSP70 concentration decreased significantly in the HHES3 group. As a result, positive effects of hesperidin supplementation in the diet were found in both heat stress and thermoneutral conditions

Real-World Outcomes of Anti-VEGF Treatment for Neovascular Age-Related Macular Degeneration in Turkey: A Multicenter Retrospective Study, Bosphorus Retina Study Group Report No: 1

Objectives: To evaluate the real-world outcomes of intravitreal anti-vascular endothelial growth factor (anti-VEGF) treatment in neovascular age-related macular degeneration (nAMD) patients. Materials and Methods: Multicenter, retrospective, interventional, non-comparative study. The records of nAMD patients treated with an anti-VEGF agent on a pro re nata treatment regimen basis between January 2013 and December 2015 were reviewed. The patients who completed a follow-up period of 12 months were included. Primary outcome measures of this study were the visit and injection numbers during the first year. Results: Eight hundred eighty eyes of 783 patients met the inclusion criteria for the study. Mean number of visits at month 12 was 6.9±2.5 (range: 1-15). Mean number of injections at month 12 was 4.1±1.9 (range: 1-11). Mean visual acuity at baseline and months 3, 6, and 12 was 0.90±0.63 LogMAR (range: 0.0-3.0), 0.79±0.57 LogMAR (range: 0.0-3.0), 0.76±0.57 LogMAR (range: 0.0-3.0), and 0.79±0.59 LogMAR (range: 0.0-3.0), respectively. Mean central retinal thickness at baseline and months 6 and 12 was 395±153 μm (range: 91-1582), 330±115 μm (range: 99-975), and 332±114 μm (range: 106-1191), respectively. Conclusion: The numbers of visits and injections were much lower than ideal and were insufficient with the pro re nata treatment regimen

Fully Automated Segmentation of Renal, Cortex and Medulla

#nofulltext# --- Tulum, Gökalp (Arel Author), Artuğ, N. Tuğrul (Arel Author), Osman, Onur(Arel Author)It is assume that volumes of cortex and medulla are related with recovery of the kidney after transplantation. In this work, a fully automated segmentation and volume calculation method is proposed for determining renal volumes. 10 kidneys of 5 donors are used as a dataset. When the output volumes of the proposed system were compared to the golden standarts, Volume error rates are obtained as %03,97 +/- 0,02for total renal volume, %8,71 +/- 0,06 for cortex volume and %20,13 +/- 0,2 for medulla volume

Tulum, Gökalp (Arel Author), Osman, Onur (Arel Author)It is assume that renal volume with cortex and medulla volumes are related with recovery of the kidney after transplantation. In this study it is aim that a semi automated method is developed for renal volumes. Theise volumes can be obtaine with some tools in the developed interface. We used 10 kidneys of 5 donors in this study. The first outputs of the method were compared to the tuned ones and it is found that the first outputs are very close to the corrected contours. Volume error rates were obtained as 0.62 +/- 0.01 for total renal volume, 1.26%+/- 0.01 for cortex volume and 1.23%+/- 0.01 for medulla volume

Simulation-based training of the rapid evaluation and management of acute stroke (stream)—a prospective single-arm multicenter trial

Introduction: Acute stroke care delivered by interdisciplinary teams is time-sensitive. Simulation-based team training is a promising tool to improve team performance in medical operations. It has the potential to improve process times, team communication, patient safety, and staff satisfaction. We aim to assess whether a multi-level approach consisting of a stringent workflow revision based on peer-to-peer review and 2–3 one-day in situ simulation trainings can improve acute stroke care processing times in high volume neurocenters within a 6 months period. Methods and Analysis: The trial is being carried out in a pre-test-post-test design at 7 tertiary care university hospital neurocenters in Germany. The intervention is directed at the interdisciplinary multiprofessional stroke teams. Before and after the intervention, process times of all direct-to-center stroke patients receiving IV thrombolysis (IVT) and/or endovascular therapy (EVT) will be recorded. The primary outcome measure will be the “door-to-needle” time of all consecutive stroke patients directly admitted to the neurocenters who receive IVT. Secondary outcome measures will be intervention-related process times of the fraction of patients undergoing EVT and effects on team communication, perceived patient safety, and staff satisfaction via a staff questionnaire. Interventions: We are applying a multi-level intervention in cooperation with three “STREAM multipliers” from each center. First step is a central meeting of the multipliers at the sponsor's institution with the purposes of algorithm review in a peer-to-peer process that is recorded in a protocol and an introduction to the principles of simulation training and debriefing as well as crew resource management and team communication. Thereafter, the multipliers cooperate with the stroke team trainers from the sponsor's institution to plan and execute 2–3 one-day simulation courses in situ in the emergency department and CT room of the trial centers whereupon they receive teaching materials to perpetuate the trainings. Clinical Trial Registration: STREAM is a registered trial at https://clinicaltrials.gov/ct2/show/NCT03228251

Incidence and clinical characteristics of acute rheumatic fever in Turkey: Results of a nationwide multicentre study

© 2021 Paediatrics and Child Health Division (The Royal Australasian College of Physicians)Aim: To evaluate the incidence and clinical features of acute rheumatic fever (ARF) in Turkey, following the revised Jones criteria in 2015. Methods: This multicentre study was designed by the Acquired Heart Diseases Working Group of the Turkish Pediatric Cardiology and Pediatric Cardiac Surgery Association in 2016. The data during the first attack of 1103 ARF patients were collected from the paediatric cardiologists between 1 January 2016 and 31 December 2016. Results: Turkey National Institute of Statistics records of 2016 were used for the determination of ARF incidence with regard to various cities and regions separately. The estimated incidence rate of ARF was 8.84/100 000 in Turkey. The ARF incidence varied considerably among different regions. The highest incidence was found in the Eastern Anatolia Region as 14.4/100 000, and the lowest incidence was found in the Black Sea Region as 3.3/100 000 (P < 0.05). Clinical carditis was the most common finding. The incidence of clinical carditis, subclinical carditis, polyarthritis, aseptic monoarthritis, polyarthralgia and Sydenham's Chorea was 53.5%, 29.1%, 52.8%, 10.3%, 18.6% and 7.9%, respectively. The incidences of clinical carditis, subclinical carditis, polyarthritis and polyarthralgia were found to be significantly different among different regions (P < 0.05). Conclusion: The findings of this nationwide screening of ARF suggest that Turkey should be included in the moderate-risk group
