Kırmızı biber, kadife çiçeği ve sentetik astaksantin' in Penaeus semisulcatus' un pigmentasyon, Büyüme ve besin bileşenleri üzerine etkisi

Başlangıç ağırlığı 11,10 ± 0,26 g olan karidesler her biri 100 mg/kg karotenoyit içeren % 6,6 kırmızı biber (RP), % 2,4 kadife çiçeği (MF), 100 mg/kg sentetik astaksantin (SA) ve karotenoyit içermeyen kontrol grubu (BD) diyetleriyle 60 gün beslenmişlerdir. Karotenoyit kaynaklarının karideslerin büyümesi üzerine bir etkisi olmamıştır (P > 0,05). En yüksek yaşama oranını SA diyeti (% 92) göstermiş ve bunu sırasıyla RP (% 82) ve diğer diyetler (% 75) izlemiştir (P 0,05). RP ve SA karideslerin kas dokusunda MF' ye göre daha fazla bir protein artışına neden olmuştur (P 0,05).Shrimps with an initial weight of 11.10 ± 0.26 g were fed diets supplemented with 6.6% red pepper (RP), 2.4% marigold flower (MF), and 100 mg/kg synthetic astaxanthin (SA), each of which contained 100 mg/kg total carotenoid, and a control diet (BD), without carotenoid supplement for 60 days. Dietary carotenoid sources did not significantly affect the growth of the shrimps (P > 0.05). SA supplementation yielded the highest survival rate (92%), followed by RP (82%) and the other diets (75%) (P 0.05). RP and SA resulted in a greater protein increase in shrimp muscle than MF (P 0.05)

The Anaesthetic Effects of Quinaldine Sulphate, Muscle Relaxant Diazepam and Their Combination on Convict Cichlid, Cichlasoma nigrofasciatum (Gunther, 1867) Juveniles

WOS: 000275982700021The goal of this study was to determine the safety dosage of anaesthetic Quinaldine Sulphate (QS) alone and together with a muscle relaxant, Diazepam (D) on Convict cichlid, Cichlasoma nigrofasciatum (0.54+/-0.01 g) juveniles for ornamental fish sector. The trial showed that the QS with D administration significantly increased the anaesthesia level in the Convict cichlid. The fish entered light anaesthesia at 9.75 ppm QS+0.5 ppm D (0.83+/-0.02 min). Moreover, a deep anaesthesia level was reached at 9.75 ppm QS+1 ppm D (1.20+/-0.09 min) as compared to 13 ppm of QS (6.40+/-0.28 min). When used together with QS and D eliminated the excitement and hyperactivity of the fish compared to QS alone. In addition, no mortality occurred in any anaesthesia levels except high concentrations (40-54 ppm QS). This study indicate that the advisable light and deep phases of anaesthesia for experimental treatments, handling, immobilization and transportation of the convict cichlid juveniles were achieved with dosages of 9.75 ppm QS+0.5 ppm D and 9.75 ppm QS+1 ppm D, respectively

Delayed colorectal cancer care during covid-19 pandemic (decor-19). Global perspective from an international survey

Background The widespread nature of coronavirus disease 2019 (COVID-19) has been unprecedented. We sought to analyze its global impact with a survey on colorectal cancer (CRC) care during the pandemic. Methods The impact of COVID-19 on preoperative assessment, elective surgery, and postoperative management of CRC patients was explored by a 35-item survey, which was distributed worldwide to members of surgical societies with an interest in CRC care. Respondents were divided into two comparator groups: 1) ‘delay’ group: CRC care affected by the pandemic; 2) ‘no delay’ group: unaltered CRC practice. Results A total of 1,051 respondents from 84 countries completed the survey. No substantial differences in demographics were found between the ‘delay’ (745, 70.9%) and ‘no delay’ (306, 29.1%) groups. Suspension of multidisciplinary team meetings, staff members quarantined or relocated to COVID-19 units, units fully dedicated to COVID-19 care, personal protective equipment not readily available were factors significantly associated to delays in endoscopy, radiology, surgery, histopathology and prolonged chemoradiation therapy-to-surgery intervals. In the ‘delay’ group, 48.9% of respondents reported a change in the initial surgical plan and 26.3% reported a shift from elective to urgent operations. Recovery of CRC care was associated with the status of the outbreak. Practicing in COVID-free units, no change in operative slots and staff members not relocated to COVID-19 units were statistically associated with unaltered CRC care in the ‘no delay’ group, while the geographical distribution was not. Conclusions Global changes in diagnostic and therapeutic CRC practices were evident. Changes were associated with differences in health-care delivery systems, hospital’s preparedness, resources availability, and local COVID-19 prevalence rather than geographical factors. Strategic planning is required to optimize CRC care
