For the first time, data on the in vitro metabolic fates of dichotomitin were revealed in this work, which would be helpful for us to understand the disposition of this bioactive constituent.Artificial insemination (AI) with cryopreserved semen is an important tool to preserve endangered species, including European donkey breeds. Sperm vitrification is an alternative method to conventional freezing using high cooling rates and non-permeable cryoprotectant agents (CPAs). In donkeys, sperm vitrification was firstly developed in spheres by directly dropping the sperm (30 µl) into the liquid nitrogen. The vitrification media contained a combination of sucrose and bovine serum albumin as non-permeable CPAs and resulted in better sperm parameters after warming than extenders containing glycerol. Thereafter, sperm vitrification was optimized using an aseptic protocol, which consists of volumes up to 160 µl vitrified at 300 million sperm/ml using 0.25-ml straws with outer covers, obtaining similar sperm parameters as conventional freezing for total motility (52.7 ± 15.6% versus. 3-Amino-9-ethylcarbazole ic50 58.2 ± 16.1%), progressive motility (44.3 ± 15.0% versus. 44.7 ± 18.2%) and plasma membrane integrity (49.2 ± 11.2% versus. 55.4 ± 9.0%), respectively. In order to vitrify larger volumes of sperm, a procedure using 0.5-ml straws was evaluated; however, this methodology failed when compared to conventional freezing or other vitrification protocols, obtaining poor sperm quality after warming. Recently, a new methodology was developed for warming 0.25-ml straws in a water bath and after AI using the vitrified sperm, the uterine inflammatory response solved faster, and pregnancy rates were greater (22%) than frozen semen (10%) but not statistically different. In conclusion, all these findings confirm that sperm vitrification can be performed in donkeys as an alternative to conventional freezing for AI in jennies.The goal of this study was to assess the feasibility of across-country genomic predictions in Norwegian White Sheep (NWS) and New Zealand Composite (NZC) sheep populations with similar development history. Different training populations were evaluated (i.e., including only NWS or NZC, or combining both populations). Predictions were performed using the actual phenotypes (normalized) and the single-step GBLUP via Bayesian inference. Genotyped NWS animals born in 2016 (N = 267) were used to assess the accuracy and bias of genomic estimated breeding values (GEBVs) predicted for birth weight (BW), weaning weight (WW), carcass weight (CW), EUROP carcass classification (EUC), and EUROP fat grading (EUF). The accuracy and bias of GEBVs differed across traits and training population used. For instance, the GEBV accuracies ranged from 0.13 (BW) to 0.44 (EUC) for GEBVs predicted including only NWS, from 0.06 (BW) to 0.15 (CW) when including only NZC, and from 0.10 (BW) to 0.41 (EUC) when including both NWS and NZC animals in the training population. The regression coefficients used to assess the spread of GEBVs (bias) ranged from 0.26 (BW) to 0.64 (EUF) for only NWS, 0.10 (EUC) to 0.52 (CW) for only NZC, and from 0.42 (WW) to 2.23 (EUC) for both NWS and NZC in the training population. Our findings suggest that across-country genomic predictions based on ssGBLUP might be possible for NWS and NZC, especially for novel traits.
Having multiple renal arteries (MRA) has been linked to hypertension development. Whether kidney donors who are left with MRA in the non-donated kidney incur a higher risk of hypertension has not been studied.

We compared the development of hypertension, reduced estimated glomerular filtration rate (eGFR), cardiovascular disease, and mortality in 2624 normotensive kidney donors with MRA in the non-donated kidney and to 2624 propensity score matched normotensive donor controls with a single renal artery.

In total, 35% of donors had MRA. Donors with MRA were less likely to have undergone a left nephrectomy (51% vs. 83%). Post-donation hypertension was associated with age, male gender, non-white ethnicity, obesity and family history of hypertension. Having MRA was not associated with risk of hypertension; aHR 0.92 (95% CI 0.82-1.03), p = 0.16. After 17±11 years from donation, a similar proportion of donors with and without MRA developed cardiovascular disease, proteinuria and eGFR <30, <45 and <60 ml/min/1.73m
and the multivariable risks of developing these outcomes were similar in the two groups.

Our study did not show increased risk for hypertension, reduced eGFR, proteinuria or cardiovascular disease in donors with multiple renal arteries in the remaining kidney and without hypertension at donation.

An optical readout is preferred for low-tech visual inspection. Here, a concept for time-temperature integrators based on colloidal crystals is introduced. Two unique features in this class of advanced materials are combined 1) the film-formation kinetics can be controlled by orders of magnitude based on mixtures of particles with distinct glass transition temperatures. 2) A gradual variation of the particle mixture along a linear gradient of the colloidal crystal enables local readout. Tailor-made latex particles of identical size but different glass transition temperatures provide a homogenous photonic stopband. The disappearance of this opalescence is directly related to the local particle ratio and the exposure to a time and temperature combination. This sensing material can be adjusted to report extended intermediate and short excessive temperature events, which makes it specifically suitable for long-term tracing and threshold applications.Hydrogels have demonstrated great potential in biomedical and engineering areas. To improve the physical performance, development of efficient physical/chemical protocols is essential. Herein, an electrochemistry functionalization strategy that is capable of enabling the functional improvements of hydrogel is reported. The electrochemistry functionalization is demonstrated on a hydrogel model of polyacrylamide (PAAm)@κ-carrageenan. The electrochemistry reaction generates metal ions (Fe3+ ) that migrate and coordinate with the sulfate groups of κ-carrageenan resulting in the prominent function improvements. In comparison with untreated PAAm@κ-carrageenan hydrogel, it can improve the mechanical strength by 7.37 times, and can increase the interfacial adhesion energy of the hydrogel on a glass surface from 0 to 1400 J m-2 , stronger than the bonding strength of tendons (adhesion energy ≈800 J m-2 ). Two pieces of hydrogel strips integrate into an intact structure by the electrochemistry functionalization, where the healing efficiency reaches 100% in comparison to the untreated hydrogel. The most significant development is that it enables functional patterning on the hydrogel by the electrode assembly, which provides the hydrogel with modular sensitivity to external pressure. Therefore, it can be a general protocol for rapid generation of multifunctional hydrogels for biomedical and engineering developments.Metal halide perovskites are emerging scintillator materials in X-ray detection and imaging. However, the vulnerable structure of perovskites triggers unreliable performance when they are utilized in X-ray detectors under cumulative dose irradiation. Herein, a self-limited growth strategy is proposed to construct CsPbBr3 nanocrystals that are embedded in a transparent amorphous network structure, featuring X-imaging with excellent resolution (≈16.8 lp mm-1 ), and fast decay time (τ = 27 ns). Interestingly, it is found that the performance degradation of the scintillator, caused by the damage from high-dose X-ray irradiation, can be fully recovered after a facile thermal treatment process. This indicates a superior recycling behavior of the explored perovskites scintillator for practical applications. The recoverability of the as-explored scintillator is attributed to the low atom-migration rate in the amorphous network with high-viscosity (1 × 1014 cP). This result highlights the practical settlement of the promising perovskites for long-term, cost-effective scintillator devices.
To investigate the significance of lymphocyte-to-monocyte ratio (LMR) combined with carbohydrate antigen (CA) 19-9 for predicting postoperative recurrence of colorectal cancer (CRC) in patients with type II diabetes.

We conducted a retrospective analysis of 106 postoperative patients with stage II-III CRC and with type II diabetes. Their clinical indexes such as LMR and CA19-9 were collected, and the patients were followed up for 5years.

The CA19-9 level was 119.7U/ml at baseline in the relapsed group, while this was 24.81U/ml in non-relapsed group (p=0.001). On the contrary, the LMR level was 5.10 and 2.57 for non-relapsed and relapsed group (p<0.001), respectively. Kaplan-Meier survival curves stratified by CA19-9 and LMR suggested that patients with lower CA19-9 had higher survival probability (p<0.001), while patients with high LMR level had higher survival probability (p<0.001). The multivariable Cox proportional hazard regression analysis with CA19-9 and LMR indicated that although the baseline CA19-9 is significantly associated with increasing risk of disease recurrence, the HR (HR=1.0, 95% CI 1.00-1.01) was small and close to 1, whereas the high baseline LMR (HR=0.44, 95% CI 0.32-0.61) was associated with decrease in disease recurrence. Model with continuous CA19-9 and LMR was able to better predict (AUC 73.17%) the disease recurrence.

LMR combined with CA19-9 may become a new index for predicting postoperative recurrence of CRC in patients with diabetes.

Native CNG channels are heterotetramers composed of homologous A and B subunits. Biallelic mutations in CNGA1 or CNGB1 genes result in autosomal recessive retinitis pigmentosa (RP). To investigate the pathogenic mechanism of CNG channel-associated retinal degeneration, we developed a mouse model of CNGA1 knock-out using CRISPR/Cas9 technology. We observed progressive retinal thinning and a concomitant functional deficit in vivo as typical phenotypes for RP. Immunofluorescence and TUNEL staining showed progressive degeneration in rods and cones. Moreover, microglial activation and oxidative stress damage occurred in parallel. RNA-sequencing analysis of the retinae suggested down-regulated synaptic transmission and phototransduction as early as 9 days postnatal, possibly inducing later photoreceptor degeneration. In addition, the down-regulated PI3K-AKT-mTOR pathway indicated upregulation of autophagic process, and chaperone-mediated autophagy was further shown to coincide with the time course of photoreceptor death. Taken together, our studies add to a growing body of research exploring the mechanisms of photoreceptor death during RP progression and provide a novel CNGA1 knockout mouse model for potential development of therapies.
