A novel Gram-negative bacterial strain BT320T was isolated from soil collected in Uijeongbu city, Korea. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain BT320T belong to a distinct lineage within the genus Flavisolibacter (family Chitinophagaceae, order Chitinophagales, class Chitinophagia). The strain BT320T was closely related to Flavisolibacter galbus 17J28-26T (97.6% 16S rRNA gene similarity), Flavisolibacter nicotianae X7XT (96.7%), Flavisolibacter ginsengiterrae Gsoil 492T (96.2%), and Flavisolibacter ginsengisoli Gsoil 643 T (96.1%). The genome size of strain BT320T was 5,664,094 bp. Bacterial growth was observed at 10-37 °C (optimum 25 °C) and pH 6.0-8.0 (optimum pH 7.0) on R2A agar. The major cellular fatty acids of strain BT320T were iso-C150, summed feature 3 (C161 ω6c/C161 ω7c), and summed feature 1 (iso-C151 H/C130 3OH). Its predominant respiratory quinone was MK-7. The major polar lipid of strain BT320T was identified to be phosphatidylethanolamine (PE). Based on the biochemical, chemotaxonomic, and phylogenetic analysis, strain BT320T can be suggested as a novel bacterial species within the genus Flavisolibacter and the proposed name is Flavisolibacter longurius. The type strain of Flavisolibacter longurius is BT320T (= KCTC 72422T = NBRC 114375T).Since its first introduction in 2003 by Kamisawa et al., IgG4-related disease has gained wide interest in the imaging community, and several manuscripts have been published regarding its imaging features. In addition to initial observations in the pancreaticobiliary system, it is now well known that the disease may involve every organ system in the body. selleck chemicals llc There is not much information in the imaging literature about the involvement of mesentery, omentum, and peritoneum in this disease. This article aims to provide more information about the imaging findings of IgG4-related disease regarding these areas by making radiopathological correlations and discussing the possible differential diagnoses.Pancreatic cystic neoplasms (PCN) comprise of a diverse array of pancreatic cysts, including intraductal papillary mucinous neoplasms (IPMN), mucinous cystic neoplasms (MCN), serous cystic neoplasms (SCN), cystic neuroendocrine tumors (cNET), and many others. Increasing use of cross-sectional imaging has resulted in greater numbers of PCNs discovered incidentally. The overall risk of malignancy is low, but can vary considerably between different classes of PCNs. Furthermore, many pancreatic cysts are indeterminate on imaging, and the inability to reliably predict the course of disease remains a challenge for radiologists. Due to the variability in disease course and a lack of high-quality studies on PCNs, there is no universal consensus when it comes to balancing optimal surveillance while avoiding the risk for overtreatment. Currently, there are three widely accepted international guidelines outlining guidelines for surveillance and management of PCNs the American Gastroenterological Association (AGA) in 2015, the International Association of Pancreatology (IAP) last revised in 2017, and the European Study Group on Cystic Tumours of the Pancreas (European) last revised in 2018. In 2017, the American College of Radiology released its own comprehensive set of recommendations for managing indeterminate pancreatic cysts that are detected incidentally on CT or MRI. The purpose of this paper is to describe the key differences between the ACR recommendations and the aforementioned three sets of guidelines regarding cyst management, imaging surveillance, performance, and cost-effectiveness.
To assess the risk of nephrogenic systemic fibrosis (NSF) in patients with renal impairment undergoing gadoxetic acid-enhanced magnetic resonance imaging.

This retrospective study included patients who had an estimated glomerular filtration rate (eGFR) below 60mL/min per 1.73m
or had undergone dialysis around the time of gadoxetic acid exposure from January 2010 to November 2019. All patients received at least one intravenous injection of gadoxetic acid at a fixed dose of 2.5mmol. The primary endpoint was the development of NSF after exposure to gadoxetic acid based on Girardi's clinicopathological scoring system.

A total of 204 patients with renal impairment received 424 injections of gadoxetic acid, of which 131 and 54 had an eGFR of 30-59 and < 30mL/min per 1.73m
, respectively, and 19 had undergone hemodialysis. Eighty-two patients received multiple injections, with 23 receiving five or more injections. The dose of each exposure ranged from 0.02 to 0.07mmol/kg and the cumulative doses ranged from 0.02 to 0.45mmol/kg. Thirty-three patients had concomitant Child-Pugh class B or C cirrhosis. No NSF was detected during follow-up (median 20months; range 6days to 111months). The upper bound of the 95% confidence interval for NSF risk was 2.2% and 1.1% per patient and examination, respectively.

No NSF was detected in this study. However, it is premature to ascertain the risk of NSF using gadoxetic acid in patients with renal impairment and further studies are warranted.

We report a 38-year-old male HCS patient with a history of multiple pathologic fractures, poor bone stock under intermittent antiresorptive therapy, and secondary osteoarthritis (OA) of the knee, in which we successfully performed total knee arthroplasty (TKA). Next to a detailed skeletal assessment including laboratory bone metabolism markers, dual energy X-ray absorptiometry (DXA), and high-resolution peripheral quantitative computed tomography (HR-pQCT), undecalcified histologic and histomorphometric analysis was performed on intraoperatively obtained tibial cut sections. This multiscale assessment revealed a severe, combined trabecular-cortical microarchitectural deterioration, increased bone turnover indices, and advanced cartilage degeneration, thus demonstrating the crucial role of Notch2 in skeletal and cartilage homeostasis, which is in line with the findings of previous mouse models.
