Anemia is a common complication of chronic kidney disease (CKD). Recombinant human erythropoietin (rHu-EPO) is used extensively in patients with CKD. However, anti-erythropoietin (anti-EPO) antibody has been reported during rHu-EPO treatment, which causes pure red cell aplasia (PRCA). We presented a case of 75-year-old man, who underwent hemodialysis for 2 years. He developed PRCA during rHu-EPO treatment. The rHu-EPO was immediately discontinued, and the patient was given roxadustat treatment. After 6 months of roxadustat treatment, the anti-EPO antibody was disappeared, and hemoglobin recovered normal range. The results suggest that roxadustat can be used to treat patients with anti-EPO antibody-mediated PRCA without immunosuppressive therapy.
There are particular challenges in the implantation of malformed cochleae, such as in cases of facial nerve anomalies, cerebrospinal fluid (CSF) leaks, erroneous electrode insertion, or facial stimulation, and the outcomes may differ depending on the severity of the malformation. The aim of this study was to assess the impact of inner ear malformations (IEMs) on surgical complications and outcomes of cochlear implantation.

In order to assess the impact of IEMs on cochlear implant (CI) outcomes, 2 groups of patients with similar epidemiological parameters were selected from among 863 patients. Both the study group (patients with an IEM) and control group (patients with a normal inner ear) included 25 patients who received a CI and completed at least 1 year of follow-up. Auditory performance, receptive and expressive language skills, and production and use of speech were evaluated preoperatively and at least 1 year after implantation. Types of surgical complications and rates of revision surgeries were dete is possible to improve communication skills with CIs in patients with IEMs despite the variations in postoperative performances. Patients with EVA, incomplete partition type 2, and cochlear hypoplasia type 2 were the best performers in terms of auditory-verbal skills. Patients with IEMs scored poorly compared to patients with normal cochleae. CSF leak (gusher or oozing) was the most common complication during surgery, which is highly likely in cases of incomplete partition type 3.
The aim of this study was to study the relationship between the formation of gastric fundic gland polyp and gastric hyperplastic polyp (HP) and the changes of gastric juice microenvironment.

The proton-pump inhibitor (PPI) applications to patients were recorded. Gastric juices and biopsy polyps were collected for pathological examination, H. pylori tests, biomarkers, and MUC1, MUC2, MUC5AC expression measurement.

Among 34,892 patients, the detection rate of gastric fundic gland polyps was significantly higher than that of gastric HPs (p < 0.01). The incidence rate of gastric fundic gland polyp and gastric HP in PPI users (n = 3,886) was higher than that of non-PPI users (p < 0.01). The occurrence of polyp was positively related to the duration of PPI application and the H. pylori-positive rate. Ciforadenant antagonist The bile reflux rate between fundic gland polys group (17.61%) and HPs (28.67%) was significantly different (p < 0.01). The levels of gastric juice Gastrin-17, epidermal growth factor (EGF) and MUC2 from patients with gastric fundic gland polyps and gastric HPs were higher than those in the control group (p < 0.01). However, patients with gastric fundic gland polyps and HPs had significantly lower gastric juice PGE2 and MUC5AC (p < 0.01).

PPI application, H. pylori infection, and bile reflux are the potential risk factors for formation of fundic gland polyps and HPs. The potential mechanism of polyps' formation can be related to the levels of Gastrin-17, EGF, MUC2, PGE2, and MUC5AC in gastric juice.

As a result the vacuum fluctuations, induced by virtual photons, can occur in a volume much lower than the free-space diffraction limit. In this work we show that, for a single doped graphene plane inside a microcavity, these enhanced vacuum interactions can produce a significant reduction in the Fermi velocity of the electrons. The effect arises because the energies of the photons are much larger than the energies of the electrons in graphene, which implies that the vacuum exchange interaction is repulsive around the Fermi level. Consequently the quasiparticle Fermi velocity decreases, in contrast with the enhancement obtained in Hartree-Fock. For THz cavities, the reduction is highly localized around the Fermi level, and is practically independent of the carrier density in graphene.The quantum confinement effect and interesting optical properties of cesium lead halide (CsPbX3; X=Cl, Br, I) perovskite quantum dots (QDs) and nanocrystals (NCs) have given a new horizon to lighting and photonic applications. Given the exponential rate at which scientific results on CsPbX3 NCs are published in the last few years, it can be expected that the research in CsPbX3 NCs will further receive increasing scientific interests in the near future and possibly lead to great commercial opportunities to realize these materials based practical applications. With the rapid progress in the single-photon emitting CsPbX3 QDs and NCs, practical applications of the quantum technologies such as single-photon emitting LED, quantum lasers, quantum computing might soon be possible. But to reach at cutting edge of stable perovskite QDs/NCs, the study of fundamental insight and theoretical aspects of crystal design is yet insufficient. Even more, it has aroused many unanswered questions related to the stability, optical and electronic properties of the CsPbX3 QDs. Aim of the present review is to illustrate didactically a precise study of recent progress in the synthesis, properties and applications of CsPbX3 QDs and NCs. Critical issues that currently restrict the applicability of these QDs will be identified and advanced methodologies currently in the developing queue, to overcome the roadblock, will be presented. And finally, the prospects for future directions will be provided.Quercetin (QCT) is an effective antioxidant, antifibrotic and wound healing agent. Silver nanoparticles (AgNPs) are an effective antimicrobial and wound healing agent and considered as gold standard for wound treatment especially diabetic and burn wounds. The present study aimed to investigate QCT loaded AgNPs in hydrogel matrices (QCT-AgNPs hydrogel) as synergistic treatment paradigms for diabetic wound. Quality by Design (QbD) approach was employed for the optimization of hydrogel preparation using carbopol-934 and aloe-vera. The developed QCT-AgNPs hydrogel was characterized for particle size, %entrapment efficiency (%EE), surface morphology, texture analysis, in-vitro drug release, skin irritation study, ex-vivo permeation study (confocal study), and antimicrobial efficacy. The optimized formulation showed particle size of ~44.1nm with smooth spherical surface morphology and ~92.09% of QCT was entrapped in QCT-AgNPs hydrogel matrices. The antimicrobial study revealed superior therapeutic efficacy of QCT-AgNPs hydrogel in comparison to marketed (MRKT) gel on S. aureus and E. coli. Moreover, in-vivo results demonstrated QCT-AgNPs hydrogel significantly (p less then 0.001) reduced the wound and increased % re-epithelization compared with diabetic control after 18 days of treatment in excision diabetic wound model. In conclusion, this study opened an avenue for the treatment of diabetic wound.A highly dispersed Mn/TiO2 catalyst, which has high efficiency for NO conversion with CO and almost completed N2 selectivity at a low-temperature range (350 - 550K), was investigated using experimental and DFT theoretical calculation. The characterization results illustrated that the catalyst assembled with nanoparticles and the Mn doping into the TiO2 surface lattice led to the formation of Mn-O-Ti configuration, which enhanced the dispersion of Mn on the body of TiO2. The DFT study mapped out the complete catalytic cycle, including reactants adsorption, oxygen vacancy generation, N2O intermediates formation, N2 formation in Eley-Rideal (ER), Langmuir-Hinshelwood (LH), and termolecular Eley-Rideal (TER) mechanisms. With thermodynamic and kinetic analysis combined with experimental results, the ER reaction process was considered to be the fundamental mechanism over the highly dispersed Mn/TiO2 catalyst. The calculation results indicated that N2O was a significant intermediate. However, the rapid N2O reduction process led to high N2 selectivity. The rate-limiting step was the deoxygenation step of NO-MnOv/TiO2 from N-O bond scission. The active site Mn-Ov pair embedded in Mn/TiO2 was responsible not only for the formation of N-Mn/TiO2 in the ER-1 step but also for the N2O deoxygenation process to make the final product N2 in the ER-2 step. The synergetic effect between Mn 3d electron and the oxygen vacancy of TiO2 were responsible for the catalytic activity of Mn/TiO2.Several chemical compounds are considered to be promising as adjuvants in the treatment of periodontitis. Antimicrobials, anti-inflammatory drugs or, more recently, pro-regenerative or antioxidant molecules have shown a very interesting potential to improve the outcomes of mechanical biofilm removal and promote the healing of the damaged tissues. However, their clinical effect is often limited by the challenge of achieving effective and prolonged drug delivery within the periodontal lesion, while limiting the risk of toxicity. In-situ forming implants are "implantable" drug-delivery systems that have gained considerable attention over the last few decades due to their multiple biomedical applications. They are liquids that, when injected at the site to be treated, form a semi-solid or solid dosage form that provides safe and locally controlled drug release. This review discusses current data and future prospects for the use of in-situ forming implants in periodontal treatment.Using numerical renormalization group calculation, we construct a dataset with 100 K samples, and train six different neural networks for the prediction of spectral functions from density of states (DOS) of the host material. We find that a combination of gated recurrent unit (GRU) network and bidirectional GRU (BiGRU) performances the best among all the six neural networks. The mean absolute error of the GRU + BiGRU network can reach 0.052 and 0.043 when this network is evaluated on the original dataset and two other independent datasets. The average time of spectral function predictions from machine learning is on the scale of 10-5-10-6that of traditional impurity solvers for Anderson impurity model. This investigation pave the way for the application of recurrent neural network and convolutional neural network in the prediction of spectral functions from DOSs in machine learning solvers of magnetic impurity problems.
