A typical ion beam treatment facility has multiple treatment rooms and may treat with more than one ion species, thus requiring a significant quality assurance (QA) effort. The goal of this work was to perform daily QA using a single irradiation per ion species to obtain the beam dosimetry parameters of dose per monitor unit (D/MU), range, and spot position. The X-ray alignment system should also be checked and the entire procedure performed by therapists.

This goal was achieved by designing a jig for the Sun Nuclear Daily QA™ 3 device and combining it with specific brass boluses, a standard QA plan, and a cuboid polyethylene phantom for positioning/repositioning tests. The design of the plan used for each ion species delivery ensured that there was no interference between the tests of the various characteristics.

The 1-year monitoring results showed the proposed daily QA procedure was reliable and able to reflect each of the specified QA items of the proton and carbon ion beams. To simplify the daily analysis, the tolerances for the D/MU, beam range, and spot position (±1.5%, ±0.3mm, ±1.5mm, respectively) are checked using only the detector readings without the need for additional data processing.

The proposed daily QA procedure was clinically implemented in our facility in April 2019 and has run smoothly for the first 2 years of operation. The total daily QA time for the four-room facility decreased from 1 to 1.5h to 30 to 40 min and was achieved not by reducing QA tests but rather by implementing new technology and procedures permitting acquisition of multiple beam information.

However, the fusion protein strategy usually requires expensive proteases to perform in vitro proteolysis and additional chromatographic steps to obtain tag-free recombinant proteins. Poly(vinylalcohol) Expression systems based on intracellular processing of solubility tags in Escherichia coli, through co-expression of a site-specific protease, simplify the recombinant protein purification process, and promote the screening of molecules that fail to remain soluble after tag removal. High yields of soluble target proteins have already been achieved using these protease co-expression systems. Herein, we review approaches for controlled intracellular processing systems tailored to produce soluble untagged proteins in E. coli. We discuss the different genetic systems available for intracellular processing of recombinant proteins regarding system design features, advantages, and limitations of the various strategies.Data regarding transthoracic echocardiography (TTE) application to obstetric patients are scant. Often, anaesthetists preparing for caesarean section are unaware of the proportion of obstetric patients who have relevant cardiac disease. This audit aimed at undertaking a retrospective analysis of TTE performed in intensive care unit patients after caesarean section. Over five years, 56 women were eligible. Echocardiographic abnormalities were deemed relevant if graded as of moderate severity. The most common reason was dyspnoea (41%). Echocardiography demonstrated structural abnormality in 29% or functional abnormality in 38%. It may be appropriate to undertake preoperative echocardiography more commonly in high-risk obstetric patients.Microfluidic impedance cytometry is a powerful system to measure micro and nano-sized particles and is routinely used in point-of-care disease diagnostics and other biomedical applications. However, small objects near a sensor's detection limit are plagued with relatively significant background noise and are difficult to identify for every case. While many data processing techniques can be utilized to reduce noise and improve signal quality, frequently they are still inadequate to push sensor detection limits. Here, we report the first demonstration of a novel signal averaging algorithm effective in noise reduction of microfluidic impedance cytometry data, improving enumeration accuracy, and reducing detection limits. Our device uses a 22 µm tall × 100 µm wide (with 30 µm wide focused aperture) microchannel and gold coplanar microelectrodes that generate an electric field, recording bipolar pulses from polystyrene microparticles flowing through the channel. In addition to outlining a modified moving signal averaging technique theoretically and with a model data set, we also performed a compendium of characterization experiments including variations in flow rate, input voltage, and particle size. Multivariate metrics from each experiment are compared including signal amplitude, pulse width, background noise, and signal-to-noise ratio (SNR). Incorporating our technique resulted in improved SNR and counting accuracy across all experiments conducted, and the limit of detection improved from 5 to 1 µm particles without modifying microchannel dimensions. Succeeding this, we envision implementing our modified moving average technique to develop next-generation microfluidic impedance cytometry devices with an expanded dynamic range and improved enumeration accuracy. This can be exceedingly useful for many biomedical applications, such as infectious disease diagnostics where devices may enumerate larger-scale immune cells alongside sub-micron bacterium in the same sample.

Emerging evidence supports a strong association between the skin and the gut. The association between seborrheic dermatitis (SD) and peptic ulcer disease (PUD) was largely unknown. This study aimed to investigate the association of SD and PUD.

This nationwide population-based cohort study was conducted using the Taiwan's National Health Insurance Research Database. A total of 19445 participants was recruited. Each patient with a diagnosis of incident SD was matched to four patients without SD using propensity scores based on age, gender, index year, insurance amount, urbanisation level, Charlson comorbidity index (CCI), the presence of comorbidities and medication use. The primary endpoint was the development of incident PUD. Hazard ratios (HRs) and corresponding 95% confidence intervals (CIs) for PUD occurrence in relation to the presence of SD were calculated.

Overall, patients with SD had a significantly higher risk for incident PUD than those without SD in both univariable (crude HR=1.60, 95% CI 1.38-1.86, P<0.001) and multivariable (adjusted HR=1.58, 95% CI 1.36-1.83, P<0.001) Cox proportional hazard regression models. Kaplan-Meier analysis indicated that the cumulative incidence of PUD was consistently higher in individuals with SD than those without SD (log-rank test, P<0.001). A higher risk of PUD was also found in individuals with SD than those without SD in all stratified analyses by age, gender, CCI and follow-up time.

Patients with SD may have a higher risk for incident PUD. Further studies are warranted to validate our findings.

However, its beneficial effects on the hyperglycemia, hyperlipidemia, and gut microbiota composition in prediabetic mice is not fully understood. The objective of this study was to investigate the efficacy of MBC in alleviating high-fat diet and streptozotocin-induced prediabetes. Herein, compared with the model control, dietary supplementation with MBC (3%, w/w) for 12 weeks significantly decreased the fasting blood glucose (24.60%), total cholesterol (15.72%), triglyceride (14.41%), and low-density lipoprotein cholesterol (22.45%). Furthermore, the improvements in glucose tolerance were reflected in the reduction of the area under the curve (AUC) and incremental AUC by approximately 23.08% and 51.18%, respectively. 16S rRNA gene sequencing of fecal microbiota suggested that MBC promoted the enrichment of beneficial bacteria (Roseburia and Bifidobacterium) and the production of short-chain fatty acids. All of the results from this study provided a scientific reference for avoiding the functional ingredients waste of MBC and expanding its application value.HECT And RLD Domain-Containing E3 Ubiquitin Protein Ligase 2, or HERC2, codes an ubiquitin ligase that has an important role in key cellular processes including cell cycle regulation, DNA repair, mitochondrial functions, and spindle formation during mitosis. While HERC2 Neurodevelopmental Disorder in Old Order Amish is a well characterized human disorder involving HERC2, bi-allelic HERC2 loss of function has only been described in three families and results in a more severe neurodevelopmental disorder. Herein, we delineate the HERC2 loss of function phenotype by describing three previously unreported patients, and by summarizing the molecular and phenotypic information of all known HERC2 missense variants and biallelic loss of function patients. Collectively, these twelve individuals present with recurring features that define a syndrome with varying combinations of severe neurodevelopmental delay, structural brain anomalies, seizures, hypotonia, feeding difficulties, hearing and vision issues, and renal anomalies. This study describes a distinct neurodevelopmental disorder, emphasizing the importance of further characterization of HERC2-related disorders, as well as highlighting the importance of ongoing work into understanding these critical neurodevelopmental pathways.Urinary fatty acid binding protein 1 (FABP1, also known as liver-type FABP) has been implicated as a biomarker of acute kidney injury (AKI) in humans. However, the precise biological mechanisms underlying its elevation remain elusive. Here, we show that urinary FABP1 primarily reflects impaired protein reabsorption in proximal tubule epithelial cells (PTECs). Bilateral nephrectomy resulted in a marked increase in serum FABP1 levels, suggesting that the kidney is an essential organ for removing serum FABP1. Injected recombinant FABP1 was filtered through the glomeruli and robustly reabsorbed via the apical membrane of PTECs. Urinary FABP1 was significantly elevated in mice devoid of megalin, a giant endocytic receptor for protein reabsorption. Elevation of urinary FABP1 was also observed in patients with Dent disease, a rare genetic disease characterized by defective megalin function in PTECs. Urinary FABP1 levels were exponentially increased following acetaminophen overdose, with both nephrotoxicity and hepatotoxicity observed.
