Horticulturists are interested in evaluating how cultivar,environment,or production system inputs can affect postharvest *** mass spectrometry approaches enable analysis of minimally processed samples under ambient conditions and offer an attractive high-throughput alternative for assessing quality characteristics in plant ***,we evaluate direct analysis in real time(DART-mS)mass spectrometry and rapid evaporative ionization-mass spectrometry(REImS)to assess quality characteristics in various pepper(Capsicum annuum L.)***-mS exhibited the ability to discriminate between pod colors and pungency based on chemical fingerprints,while REImS could distinguish pepper market class(e.g.,bell,lunchbox,and popper).Furthermore,DART-mS analysis resulted in the putative detection of important bioactive compounds in human diet such as vitamin C,p-coumaric acid,and *** results of this study demonstrate the potential for these approaches as accessible and reliable tools for high throughput screening of pepper quality.

Introduction: Open surgery is gradually being supplanted by minimally invasive surgical techniques worldwide. Our study aimed to describe the place of minimally invasive surgery at the Hôpital Général Idrissa Pouye (HOGIP) in Dakar. materials and methods: This is a descriptive cross-sectional study over a 20-years period from 1st June 2000 to 31st December 2021 in the urology department of HOGIP in Dakar. The list of all surgical procedures performed was computed. We evaluated the distribution of minimally invasive procedures (endoscopy, PCNL, laparoscopy) overall and over the years. We made calculations of proportions and statistical significance was considered for alpha = 0.05. Results: In 20 years, 14,855 surgical procedures were performed, of which 5344 (36%) were minimally invasive surgeries. The average age of men was 53.19 years (standard deviation: 21.77) vs 47.32 years (standard deviation: 18.43) for women. minimally invasive procedures in the lower urinary tract accounted for 71.93% and involved 1033 cystoscopies (26.87%), 1020 Trans Urethral Resection of Prostate (TURP) (26.53%), 931 Direct Vision Internal Urethrotomy (DVIU) (24.21%, and 612 Trans Urethral Resection of the Bladder (TURB) (15.92%). In the upper urinary tract, 1461 (28.07%) minimally invasive procedures were performed, including PCNL in 193 cases (3.61%), laser endopyelotomy in 104 cases (1.95%), ureteroscopy in 486 cases (1.7%) and laparoscopy in 39 cases (0.46%). The proportion of minimally invasive surgery has gradually increased. Among the 5344 minimally invasive procedures, 333 (5.23%) were performed in 2000-2004 and 2332 (43.63%) in 2015-2019. Conclusion: minimally invasive surgery represents an important part of the activity of the HOGIP urology department. Its development has improved over the years offering its advantages to the patients.
