The current study aimed to evaluate different CBCT exposure protocols and influencing factors affecting the subjective image quality of scans taken for endodontic indications.

Twelve extracted teeth, comprising of two sets of maxillary molars, premolars, canines and incisors, mandibular premolars, and molars, were endodontically treated, and either received a fiber or metal post. The teeth were scanned by CBCT imaging before and after root canal treatment, and after post insertion. Each scan was performed thrice, using an ultra low dose (ULD), standard (SM), and high-resolution mode (HR), respectively. read more Twelve observers-4 endodontists, 4 periodontists, and 4 radiologists-assessed the subjective image quality using visual analogue scales (VAS). Potential influencing factors were evaluated including acquisition mode, observer specialty, stage of treatment, type of post, and type of tooth, using one-way ANOVA and T test.

Teeth scanned with the ULD had the highest average VAS score (72.5), followed by HR (70.2), and SM (69.0) for values pooled from all teeth and observers. CBCT acquisition mode was not a significant influencing factor on the VAS scores. Observer specialty, stage of treatment, type of post, and type of tooth were significant influencing factors.

Based on the present in vitro data, a low-dose CBCT mode seems not to negatively affect the perception of image quality.

The findings from this in vitro study demonstrate that a low-dose CBCT mode might have potential for diagnostics prior to or following endodontic treatment.

With the population aging, there is an associated rise in the prevalence of adult degenerative scoliosis (ADS). However, limited data were found to elaborate the trend of ADS research. Our study aims to investigate the global trend of ADS research in this decade.

ADS-related publications from 2010 to 2019 were extracted from the Web of Science and Medline database. Excel 2016, GraphPad Prism 6, and VOSviewer software were adopted to analyze the search results for number of publications, citation, and H-index.

A total of 1282 papers were included and were cited 16,770 times. The USA accounted for 40.41% of the articles, 60.35% of the citations, and the highest H-index of 51. China ranked second in total number of articles, third in citation frequency (1373), and fourth with an H-index of 18. The journal Spine (IF = 2.903, 2019) had the highest number of publications. Shaffery CI published the most articles in this field (40). Key words of ADS research were classified into three clusters "Surgical technique," "Mechanism," and "Radiological parameter." The "Radiological parameter" cluster became the most popular, and it came with the latest hot spots of "slope," "cervical lordosis," "mismatch," and "PI-LL."

Literature growth in ADS was rapidly expanding in this decade. The USA was the most productive country and also had a largest quantity of top authors and institutes, so that scholars can keep following and cooperated with. Radiological parameter was an emerging topic and might also be a hot spot in the near future.

Of particular interest was the presence of electrolytes containing ions which are prone to present solute-solute interactions or to crystallize. Without and at low concentration of glucose (≤ 5 g/L), the increasing concentration of electrolytes (nominal ionic strength 0-0.43 M), up to a critical value, enhanced the volumetric mass transfer coefficient (kLa) and the availability of specific interfacial area (a), due to the inhibition of bubble coalescence. As the glucose concentration increased (10-40 g/L), the enhancing effects of electrolytes were gradually lost. The glucose interacted with electrolytes, reducing their ability to inhibit coalescence and to enhance the kLa. Salt crystallization occurred independently of the addition of glucose; however, it did not have significant effect on mass transfer. Finally, the changes in physicochemical properties were highly collinear with composition variables.
Disrupted intracellular Ca
handling is known to play a role in diabetic cardiomyopathy but it has also been postulated to contribute to obesity- and type 2 diabetes-associated skeletal muscle dysfunction. Still, there is so far very limited functional insight into whether, and if so to what extent, muscular Ca
homeostasis is affected in this situation, so as to potentially determine or contribute to muscle weakness. In differentiated muscle, force production is under the control of the excitation-contraction coupling process upon plasma membrane electrical activity, the Ca
1.1 voltage sensor/Ca
channel in the plasma membrane triggers opening of the ryanodine receptor Ca
release channel in the sarcoplasmic reticulum (SR) membrane. Opening of the ryanodine receptor triggers the rise in cytosolic Ca
, which activates contraction while Ca
uptake by the SR ATPase Ca
-pump promotes relaxation. These are the core mechanisms underlying the tight control of muscle force by neuronal electrical activity. llular Ca2+ handling and excitation-contraction coupling in skeletal muscle fibres are not primary targets of obesity and type 2 diabetes. Graphical abstract.Epidemiologists have for many decades reported on the patterns and distributions of diabetes within and between populations and have helped to elucidate the aetiology of the disease. This has helped raise awareness of the tremendous burden the disease places on individuals and societies; it has also identified key risk factors that have become the focus of diabetes prevention trials and helped shape public health recommendations. Recent developments in affordable high-throughput genetic and molecular phenotyping technologies have driven the emergence of a new type of epidemiology with a more mechanistic focus than ever before. Studies employing these technologies have identified gene variants or causal loci, and linked these to other omics data that help define the molecular processes mediating the effects of genetic variation in the expression of clinical phenotypes. The scale of these epidemiological studies is rapidly growing; a trend that is set to continue as the public and private sectors invest heavily in omics data generation.
