Central venous catheter insertion in the internal jugular vein(IJV)is frequently performed in acute care settings,facilitated by its easy availability and increased use of ultrasound in healthcare settings.Despite the increased safety profile and insertion convenience,it has complications.Herein,we aim to inform readers about the existing literature on the plethora of complications with potentially disastrous consequences for patients undergoing IJV cannulation.

Betalains are natural coloring pigments with betalamic acid as the core structure of all subclasses.Besides their coloring properties,betalains exhibit various biological activities,including antioxidant and anti-inflammatory properties,which are highly imperative.Further in-vivo studies reported that betalains protect various body organs,leading to health enhancement.Body organs,including the heart,liver,kidney,lung,etc.,are important for a healthy life.However,these organs can be affected or damaged by various stress factors,toxicants,and harmful substances.Recent studies have claimed that betalains could protect all vital organs of the body through antioxidant and anti-inflammatory mechanisms.This review article described the in-vivo antioxidant and anti-inflammatory activities of betalains in various cell-line or animal models.A comprehensive discussion has been provided on the mechanism of action of betalains in protecting various body organs,including cardio-protective effect,hepato-protective ability,renal protection capacity,repro-protective ability,neuro-protective effect,lung protection,and gut protection ability.Finally,future research directions and conclusions have been outlined.

The transition metal manganese （Mn） is indispensable for photoautotrophic growth since photosystem II （PSII） employs an inorganic Mn4CaOs cluster for water splitting. Here, we show that the Arabidopsis membrane protein CHLOROPLAST MANGANESE TRANSPORTER1 （CMT1） is involved in chloroplast Mn homeostasis. CMT1 is the closest homolog of the previously characterized thylakoid Mn transporter PHOTOSYNTHESIS-AFFECTED MUTANT71 （PAM71）. In contrast to PAM71, CMT1 resides at the chloro- plast envelope and is ubiquitously expressed. Nonetheless, like PAM71, the expression of CMT1 can also alleviate the Mn-sensitive phenotype of yeast mutant qomrl. The cmtl mutant is severely suppressed in growth, chloroplast ultrastructure, and PSII activity owing to a decrease in the amounts of pigments and thylakoid membrane proteins. The importance of CMT1 for chloroplast Mn homeostasis is demonstratedby the significant reduction in chloroplast Mn concentrations in cmtl-1, which exhibited reduced Mn binding in PSII complexes. Moreover, CMT1 expression is downregulated in Mn-surplus conditions. The pam71 cmtl-ldouble mutant resembles the cmtl-f single mutant rather than pare71 in most respects. Taken together, our results suggest that CMT1 mediates Mn2 uptake into the chloroplast stroma, and that CMT1 and PAM71 function sequentially in Mn delivery to PSII across the chloroplast envelope and the thylakoid membrane.

引言:在临床中,牙龈退缩和膜龈异常是最常遇到的问题。数年来,人们对牙龈退缩和膜龈异常的治疗采取了各种不同的治疗方式,其中游离软组织移植术被广泛应用。众所周知,腭部具有与角化龈相似的组织结构,最适合进行游离软组织移植术（口腔内自体移植）。游离软组织移植术最常用的两种术式是游离龈移植术和结缔组织移植术。尽管游离软组织移植术已经被证明在治疗膜龈异常和牙龈退缩问题方面有益,但自体移植会造成第二个创口,局部并发症的发生和术后不适的可能性增加,这会导致患者可接受程度较低。因此,本研究的目的是通过系统地评价已发表的文献,探究有或无辅助手段的情况下最有效的移植获取技术,以最大限度减少腭部供区术后并发症的发生。材料和方法:在PubMed,Cochrane图书馆和Embase数据库使用相关关键词进行仅限英语的全面检索,检索时限为2000年1月至2020年12月。纳入的研究为随机对照试验,比较在有或无辅助手段的情况下不同类型的移植获取技术,辅助材料如透明质酸,富血小板纤维蛋白,血小板浓缩液,药用植物提取物,止血胶原蛋白,氰基丙烯酸酯和低水平激光治疗。研究仅限人体试验,随访时间至少一周。通过Cochrane协作工具对选定的文献进行质量评估,以评估偏差的风险。结果:共找到来自PubMed的1428篇文献,Cochrane图书馆的27篇文献和Embase数据库的23篇文献。此外,通过筛选所选文献的目录,发现数据库中缺少3篇文献。使用endnote x7.***.1.0软件删除了重复和不相关的文献,并对38篇文献进行了全文审查。最终纳入24篇文献。研究发现,结缔组织移植术更为保守,可显著降低术后并发症的发生。此外,各种辅助材料与游离龈移植术一起使用可显著降低术后一周并发症的发生。然而,在获取移植物后用低水平激光治疗进行光生物调节,没有明显降低供区部位的术后并发症发生。结论:供区创面覆盖2mm以上的软组织或辅助材料可显著降低术后一周并发症的发生。

Introduction: The incidence of head and neck cancers has increased markedly over the last decade. A Danish study of the costs of head and neck cancers has not been undertaken. Such studies have again become relevant due to the development of the HPV vaccines, as some cases are attributable to high-risk HPV 16 or 18. The objective of study was to estimate the incidence of head and neck cancers and their health care costs. Methods: Data on incidence and health care use related to head and neck cancer were obtained from Danish health care registers. New cancer patients were identified in the Danish National Cancer Register. Resource use per year in the hospital sector was estimated using data from the National Patient Register applying charges as cost estimates. Health care consumption by cancer patients was compared with that by an age- and sex-matched cohort without cancer. Results: We found that nearly 1000 new cases of oral cavity, oropharyngeal, hypopharyngeal and laryngeal cancer are diagnosed annually. In total the cost of these cancers to the Danish hospital sector constituted 31.6 million Euros per year, with the majority of costs (74%) occurring in men. The total costs associated with HPV16/18-related head and neck cancers were estimated to be 6.1 million Euros per year. Conclusion: This study provides the first Danish estimates of the costs associated with non-cervical and non-genital HPV-related cancers based on very reliable, individual-based data. It is expected that the current HPV vaccination programme will reduce this burden.
