Aim was to study the early impact of acuity circle-based allocation implementation system on liver transplantation for hepatocellular carcinoma (HCC) patients.

We assessed characteristics of HCC and non-HCC deceased donor orthotopic liver transplants (OLT) in the year before (2/2019-2/2020) and after (3/2020-2/2021) introduction of the acuity circle policy using the Organ Procurement and Transplantation Network (OPTN)/United Network for Organ Sharing (UNOS) database.

Total OLTs reduced from 6699 in the preacuity circle era to 6660 in the postacuity circle era (-.6%); this decrease is mostly driven by a decrease in HCC transplants (1529 to 1351; -11.6%). Six out of 11 regions had a reduction in the absolute number and percentage of HCC transplants with significant reductions in regions 2 (-37.8%, p<.001) and 4 (-28.3%, p=.001).

The introduction of median model for end-stage liver disease (MELD) at transplant minus 3 (MMaT-3) exception points, has created differential opportunities for HCC patients, in low-MELD as opposed to high-MELD areas, despite having the same disease. This effect has become more prominent following the implementation of acuity circle-based allocation system. Ongoing investigation of these trends is needed to ensure that HCC patients are not disparately disadvantaged due to their location.

To evaluate postoperative complications following robot-assisted radical cystectomy in patients diagnosed with bladder cancer and reveal if there are predictors for postoperative complications.

Prospectively collected medical records of 730 robot-assisted radical cystectomy patients between 2007/04 and 2019/05 in 13 tertiary referral centers were reviewed. Perioperative outcomes were compared between two groups by postoperative complications (complication vs non-complication). We assessed recurrence-free survival, cancer-specific survival, and overall survival between groups. Regression analyses were implemented to identify factors associated with postoperative complications.

Any total and high-grade complication (Clavien-Dindo grade ≥3) rates were 57.8% and 21.1%, respectively. Patients in complication group had significantly higher proportion of diabetes mellitus (P = 0.048), chronic kidney disease (P = 0.011), dyslipidemia (P < 0.001), longer operation time (P = 0.001), more estimated blood loss (demia, or a relatively large intraoperatively infused fluid volume are more likely to develop postoperative complications. Patients with postoperative complications might have a possibility of lower cancer-specific survival rate.Rechargeable aqueous Zn-Mn batteries have garnered extensive attention for next-generation high-safety energy storage. However, the charge-storage chemistry of Zn-Mn batteries remains controversial. Prevailing mechanisms include conversion reaction and cation (de)intercalation in mild acid or neutral electrolytes, and a MnO2 /Mn2+ dissolution-deposition reaction in strong acidic electrolytes. Herein, a Zn4 SO4 ·(OH)6 ·xH2 O (ZSH)-assisted deposition-dissolution model is proposed to elucidate the reaction mechanism and capacity origin in Zn-Mn batteries based on mild acidic sulfate electrolytes. In this new model, the reversible capacity originates from a reversible conversion reaction between ZSH and Znx MnO(OH)2 nanosheets in which the MnO2 initiates the formation of ZSH but contributes negligibly to the apparent capacity. The role of ZSH in this new model is confirmed by a series of operando characterizations and by constructing Zn batteries using other cathode materials (including ZSH, ZnO, MgO, and CaO). This research may refresh the understanding of the most promising Zn-Mn batteries and guide the design of high-capacity aqueous Zn batteries.

The laboratory test results and serum-specific antibodies of patients with acute brucellosis initial infection were followed up and analyzed.

70 patients in Hohhot City, Inner Mongolia Autonomous Region, with acute brucellosis were followed up for 360days. Serum samples were collected at 0, 15, 30, 60, 90, 180, and 360days after diagnosis and analyzed by Rose Bengal plate test (RBPT), colloidal gold test paper (GICA), and test tube agglutination test (SAT). The serum-specific antibodies IgG and IgM were detected.

RBPT results False negative (-) gradually increased with the extension of the course of disease, with the largest change in 30-60days after diagnosis, and the constituent ratio increased by 12.9%. GICA results The false negative increased with the course of disease, and the constituent ratio of false negative was 20.0% after 180days of diagnosis. SAT results 1100 positive showed a ladder like decrease with the increase in the course of disease, and the largest decrease was 90-180days, with a decrease of 34.3% in the constituent ratio. 360days after diagnosis, the constituent ratio of positive was only 14.3%. During the follow-up period, the IgG average value fluctuated and the average IgM value decreased.

The false-negative results of RBPT, GICA, and SAT increased with the course of disease, and the false-negative rates were higher than 20% after half a year. IgM level is beneficial to the early diagnosis of brucellosis, while IgG level is helpful to the judgment of brucellosis stage.

Mixed gangliocytoma-pituitary adenoma (MGPA) is a rare clinical entity in which gangliomatous cells are intermixed with adenomatous cells. This tumor has been estimated to account for 0.52-1.26% of all pituitary tumors. We report a rare case of MGPA in a patient with MEN1. A retrospective chart review was conducted on a patient with MEN1 diagnosed with MGPA in 2019 at a single tertiary academic medical center. A review of the literature was performed on MGPA and pituitary adenoma in MEN1. MGPA is rare, with only 174 cases previously reported in the literature and only three prior case reported in a patient with MEN1. There are multiple hypotheses regarding their pathogenesis, and it is unclear whether the MEN1 gene (menin) plays a role in the pathogenesis of MGPA. This tumor in MEN1 is a rare clinical entity of unknown etiology. Further studies are required with difficulty due to its low incidence.

In the development of commercial quadrupole mass spectrometers, there is an interest in understanding the factors that affect the transmission and peak shape of ions passing through the mass filter. These include the ion collection effects of the ion optics that lead to the presence of a peak structure.

The peak structure can be observed by increasing the ion’s axial kinetic energy and reducing the mass step size in a mass spectrum. The calculation of the maxima in the peak structure can be achieved by first obtaining the Mathieu characteristic parameter β

from the scan lines for each mass. The ion’s secular frequency, ω

, along with the ion’s transit time through the mass filter can then be used to calculate the location of the maxima in the peak structure.

Experimentally, a peak structure has been observed for m/z 42, m/z 118 and m/z 622 in the Q1 scan mode of a triple quadrupole mass spectrometer. The peak structure has shown a dependency on the ion’s axial kinetic energy, but, a mass independency with regard to the number of maxima is observed in the peak structure. In the Q3 scan mode, there is an absence of the peak structure due to the ion collection efficiency of the HED detection system.

Under the right conditions, the peak structure due to ion collection effects can be observed with a quadrupole mass filter operated in the Mathieu first stability region. The presence of the peak structure has been shown to depend upon the ion collection effects at the exit of the mass filter.

To determine whether the surface treatment of zirconia affects biofilm formation in an in vitro three-species biofilm model and in situ.

Zirconia surfaces considered for the transmucosal portion of a zirconia implant were compared with polished pure titanium grade 4 (Tp). Disks 13mm in diameter of either polished (Zp), polished and heat-treated (Zpt), machined (Zm), machined and heat-treated (Zmt) and sandblasted, etched and heat-treated (Z14) zirconia were fabricated. Surface roughness and wettability of specimens was measured. Biofilm formation was evaluated by safranin staining and scanning electron microscopy (SEM) using a three-species model, and intraorally with 16 volunteers carrying oral splints in two independent experiments. Relative biofilm formation was compared with Kruskal-Wallis followed by Bonferroni post hoc test (α=0.05).

In vitro biofilm formation with optical density values on Zp (0.14±0.01), Zpt (0.14±0.02), Zm (0.13±0.01) and Zmt (0.13±0.01) was significantly lower than on Tp (0.21±0.05) and Z14 (0.20±0.04) (p<.05). Ac-FLTD-CMK concentration In situ biofilm formation was significantly higher on Z14 (0.56±0.45) (p<.05), while no significant differences in optical density were observed among Zp (0.25±0.20), Zm (0.36±0.34) and Tp (0.28±0.22). SEM analysis supported quantitative findings.

In the in vitro, three-species biofilm model differences in material and surface roughness affected biofilm formation. In situ biofilm formation was mainly affected by the surface roughness of the specimens. Polishing of zirconia is recommended to reduce biofilm formation, while heat treatment has no significant effect.

However, realizing these materials (especially lifetime over 0.1 s) is a challenge, mainly because of non-radiative quenching of their long-lived excitons. Herein, a universal strategy of stepwise Förster resonance energy transfer (FRET) for a bright NIR system with remarkable persistent luminescence (up to 0.2 s at 810 nm) is presented, based on a new triphenylene-dye-doped polymer (triphenylene-2-ylboronic acid@poly(vinyl alcohol) (TP@PVA)) with a persistent blue phosphorescence of 3.29 s. This persistent NIR luminescence is demonstrated for application not only in NIR anti-counterfeiting but also NIR bioimaging with penetrating a piece of skin as thick as 2.0 mm. By co-doping a red dye (such as Nile red) and an NIR dye Cyanine 7 (Cy7) into this doped PVA film, the shortage of spectral overlap between TP emission and Cy7 absorbance is successfully solved, through a stepwise FRET process involving triplet to singlet (TS)-FRET from TP to the intermediate red dye and then singlet to singlet (SS)-FRET to Cy7.
