AIM： To determine the effects of high osmolarity contrast media （HOCM） and iso-osmolar contrast media （CM） application, with or without pressure, on hepato-pancreato-biliary （HPB） system. METHODS： Sixty rats were divided into six equal groups as follows： Group i：（0.9% NaCl, control）, Group 2：（diatrizoate meglumine Na, ionic HOCM, Urographin）, Group 3：（iodixanol, iso-osmolar nonionic CM, Visipaque）; each of which was applied without pressure, whereas the animals of the remaining three groups （1p, 2p, 3p） were subjected to the same CM with pressure. We performed a duodenal puncture and introduced a catheter into the ampulla. After the catheterization, 0.2 mL CM or 0.9% NaCI was injected with or without pressure. Blood samples were taken for biochemical evaluations. The histopathological examinations of liver, common bile duct, and pancreas were performed. RESULTS： There were no significant differences between the six groups for blood amylase, alanine aminotransferases, aspartate aminotransferases, bilirubin levels （P 〉 0.05）. Alkaline phosphatase and γ glutamyl transaminase levels were higher （P 〈 0.05） in the Urographin groups （2, 2p） than the Visipaque groups （3, 3p）, or control groups （1, 1p）. Hepatocyte necrosis, portal area inflammation, and Kupffer＇s cell hyperplasia were higher （P 〈 0.05） in the study groups than the control group. However, there were no significant differences （P 〉 0.05） between HOCM （2, 2p） and iso-osmolar CM （3, 3p） groups. Bile duct proliferation and regeneration in the Urographin groups （2, 2p） were significantly higher （P 〈 0.05） than the Visipaque~ groups （3, 3p） or the control groups （1, lp）. Although CM caused minor damage to the pancreas, there were no statistically significant differences （P 〉 0.05） between the groups. Application of the CM with pressure did not cause additional damage to the HPB system. CONCLUSION： Iso-osmolar, non-ionic CM could be more reliable than the ionic HOCM, whereas the application of pressure during the

Background:The impact of the coronavirus disease 2019(COVID-19)pandemic on patient decision making remains *** study aimed to investigate the effect of the pandemic on treatment preferences of patients with proximal ureteral stones.Materials and methods:Retrospective data regarding treatment preferences of patients diagnosed with symptomatic proximal ure-teral stones between July 2018 and November 2021 at a single center were *** from 493 patients were analyzed according to 2 groups,including patients diagnosed during the COVID-19 pandemic and those diagnosed during an equivalent period of time be-fore the pandemic.Results:Preference for conservative treatment increased during the COVID-19 pandemic(p=0.009).In patients who had previously undergone shock wave lithotripsy(SWL),the preference for SWL decreased and the preference for conservative treatment increased during the COVID-19 pandemic(p=0.042).Multiple logistic regression analysis revealed a significant correlation between a preference for conservative treatment during the pandemic and no prior spontaneous stone passage(p=0.003;odds ratio[OR],2.48;95％con-fidence interval[CI],1.45-4.23),no hydronephrosis(p=0.035;OR,3.57;95％Cl,1.34-9.49),and a visual analog scale score of 4 or less(p=0.018;OR,1.97;95％Cl,1.15-3.38).Conclusions:A significant increase in the preference for conservative treatment was observed among patients diagnosed during the pandemic,and patients with a history of SWL demonstrated a preference shift from SWL to conservative treatment.

Shkorfu Serkan kurt Fatih Atalar Ali Olamat Aysel Ersoy Department of Electrical and Electronic Engineering Istanbul University-Cerrahpa&scedila Avc&imathlar Istanbul Türkiye Department of Electronics and Communication Engineering Y&imathld&imathz Technical University Istanbul Türkiye Department of Bioengineering Y&imathld&imathz Technical University Istanbul Türkiye

Background/Aims: Determining the levels of oral health and the quality of dental care are fundamental to building concepts of oral health. This study aims to assess toothbrushing techniques using a technical and physical model, clarifying how children and pre-adults learn to brush their teeth. Materials and Methods: Data were recorded from 23 participants, both male and female of various ages, using a proposed electronic toothbrush equipped with X-Y-Z axes pathways. The data, collected before and after training experiments, were processed with MATLAB to generate plots for the three axes. Results: The study revealed that most parameter values, such as Mean Difference Between Amplitudes (MAV, 6.00), Wilson Amplitude (WAMP, 179.419), and Average Amplitude Coupling (AAC, 1.270), decreased from before to after the experiments. Furthermore, the average overall epoch lengths (AVG) showed a 75% reduction in movement amplitude between the two experiments. Conclusion: Dentist observations indicated which brushing methods were acceptable or not. Analytical values suggest that individuals learn the toothbrushing technique effectively, and medical observations clearly demonstrate the success of the proposed method.

近年来,Meta一直在逐步淡化政治氛围,面对即将举行的美国总统大选,身为CEO的扎克伯格极力表现出无党派倾向,随着2024年美国大选临近,社交媒体再度陷入可能干预选举的巨大争议之中,Meta也不例外。美国共和党总统候选人、前总统唐纳德·特朗普(Donald Trump)在9月出版的新书中声称,Meta首席执行官马克·扎克伯格在2020年美国总统选举期间曾密谋阻挠他当选。特朗普还放下狠话称,如果再次这么做,扎克伯格“将在监狱中度过余生”。这是特朗普对扎克伯格的最新攻击,这位前总统曾多次秤击对方干预了上届大选。
