作者： frank.c. Fan Sam choi c. c. Jiang AFc Technology co. Ltd. Shenzhen 518104 China

A novel method for a full-parallax three-dimensional （3D） holographic display by means of a lens array and a holographic functional screen is proposed. The process of acquisition, coding, restoration, and display is described in detail. It provides an efficient way to transfer the two-dimensional redundant information for human vision to the identifiable 3D display for human eyes. A holo-video system based on a commercial 4 K fiat-panel displayer is demonstrated as the result.

良性嗜铬细胞瘤和副神经节瘤通常可以通过手术切除治愈,但转移性疾病的治疗在疾病控制和症状控制方面都存在挑战。幸运的是,有几种治疗方式可用于转移性疾病的治疗,包括化疗、放射治疗和外科手术。放射性核素标记的间碘苄胍(MIBG)和生长抑素受体显像为将这些放射性药物用作诊疗剂奠定了基础。^(131)I-MIBG治疗神经内分泌肿瘤历史悠久,美国食品与药品监督管理局最近批准将高比活度^(131)I-MIBG用于治疗转移性或不可手术的嗜铬细胞瘤或副神经节瘤,使^(131)I-MIBG的治疗应用更加广泛,并重新引起人们的兴趣。尽管已有文献报道使用90Y-或177Lu-1,4,7,10-四氮杂环十二烷-1,4,7,10-四乙酸(DOTA)偶联的生长抑素类似物对嗜铬细胞瘤和副神经节瘤进行多肽受体放射性核素治疗,但随着177Lu-DOTA-D-苯丙氨酸1-酪氨酸3-苏氨酸8-奥曲肽(DOTATATE)在美国和欧洲获批,以及美国国家综合癌症网络指南建议将其用于转移性或不可手术的嗜铬细胞瘤和副神经节瘤患者,这些药物引起了人们新的兴趣。已有证据表明这些放射性药物是对转移性或无法手术的嗜铬细胞瘤或副神经节瘤患者有效的姑息治疗方法。在该篇继续医学教育文章中,作者讨论了使用^(131)I-MIBG和90Y-或177Lu-DOTA生长抑素类似物治疗嗜铬细胞瘤和副神经节瘤。

Background The study objective was to test the hypothesis that low crude protein(cP)diet with crystalline amino acids(cAA)supplementation improves Lys utilization efficiency for milk production and reduces protein turnover and muscle protein *** lactating multiparous Yorkshire sows were allotted to 1 of 2 isocaloric diets(10.80 MJ/kg net energy):control(cON;19.24%cP)and reduced cP with“optimal”AA profile(OPT;14.00%cP).Sow body weight and backfat were recorded on d 1 and 21 of lactation and piglets were weighed on d 1,14,18,and 21 of *** d 14 and 18,a subset of 9 sows(cON=4,OPT=5)was infused with a mixed solution of 3-[methyl-2H3]histidine(bolus injection)and[13c]bicarbonate(priming dose)first,then a constant 2-h[13c]bicarbonate infusion followed by a 6-h primed constant[1-13c]lysine *** blood and milk sampling were performed to determine plasma and milk Lys enrichment,Lys oxidation rate,whole body protein turnover,and muscle protein *** Over the 21-d lactation period,compared to cON,sows fed OPT had greater litter growth rate(Pcompared to cON,sows fed OPT had greater efficiency of Lys(Pciency(Pcompared to cON,sows fed OPT tended to have lower whole body protein breakdown rate(P=0.069).Muscle protein breakdown rate did not differ between OPT and cON(P=0.197).conclusion Feeding an improved AA balance diet increased efficiency of Lys and reduced whole-body protein turnover and protein *** results imply that the lower maternal N retention observed in lactating sows fed improved AA balance diets in previous studies may be a result of greater partitioning of AA towards milk rather than greater body protein breakdown.

We assessed the global incidence, mortality, and disability-adjusted life years(DALYs) associated with various liver diseases, including alcohol-related liver disease(ALD), hepatitis B/c virus infections(HBV or HcV), liver cancer, metabolic dysfunction-associated steatotic liver disease(MASLD), and other chronic liver diseases, from the 2019 Global Burden of Disease study. Additionally, we analyzed the global trends in hepatology research and drug development. From 2000 to 2019, prevalence rates increased for ALD, MASLD and other liver diseases, while they decreased for HBV, HcV, and liver cancer. countries with a high socio-demographic index(SDI) exhibited the lowest mortality rates and DALYs. The burden of liver diseases varied due to factors like sex and region. In nine representative countries, MASLD,along with hepatobiliary cancer, showed highest increase in funding in hepatology research. Globally, the major research categories in hepatology papers from 2000 to 2019 were cancer, pathobiology, and MASLD. The United States(U.S.) was at the forefront of hepatology research, with china gradually increasing its influence over time. Hepatologists worldwide are increasingly focusing on studying the communication between the liver and other organs, while underestimating the research on ALD. cancer, HcV, and MASLD were the primary diseases targeted for therapeutic development in clinical trials. However, the proportion of new drugs approved for the treatment of liver diseases was relatively low among all newly approved drugs in the U.S., china, Japan, and the European Union. Notably, there were no approved drug for the treatment of ALD in the world.
