LiCoO2 is used as a cathode material for lithium-ion batteries, however, cationic/anodic-redox-induced unstable phase transitions, oxygen escape, and side reactions with electrolytes always occur when charging LiCoO2 to voltages higher than 4.35 V, resulting in severe capacity fade. Reported here is Mg-pillared LiCoO2 . Dopant Mg ions, serving as pillars in the Li-slab of LiCoO2 , prevent slab sliding in a delithiated state, thereby suppressing unfavorable phase transitions. Moreover, the resulting Li-Mg mixing structure at the surface of Mg-pillared LiCoO2 is beneficial for eliminating the cathode-electrolyte interphase overgrowth and phase transformation in the close-to-surface region. Mg-pillared LiCoO2 exhibits a high capacity of 204 mAh g-1 at 0.2 C and an enhanced capacity retention of 84 % at 1.0 C over 100 cycles within the voltage window of 3.0-4.6 V. In contrast, pristine LiCoO2 has a capacity retention of 14 % within the same voltage window.

Orally administered angiotensin II receptor blockers (ARBs) decrease intraocular pressure (IOP). Topical administration may reduce systemic side effects and result in a useful glaucoma drug. The aim of this study is to test the ocular delivery and pharmacologic effect of nanoparticle eye drops containing ARBs (e.g. irbesartan and candesartan).

1.5% irbesartan and 0.15% candesartan eye drops were applied to rabbits. The pharmacokinetics in cornea and aqueous humour after single eye drop application were studied in 49 rabbits. The effect of the eye drops on IOP was studied in 10 rabbits using an iCare (® TonoVet Plus, iCare, Finland) tonometer and compared with 0.5% timolol eye drops.

Candesartan lowered IOP from 24.6±5.1mmHg at baseline to 19.0±2.9mmHg (mean±SD, p=0.030, n=10) 4hr after application. Irbesartan lowered IOP from 24.2±1.7mmHg to 20.2±0.9mmHg (p=0.14, n=10). Timolol decreased the IOP from 24.9±4.2mmHg to 20.4±4.8mmHg (mean±SD, p=0.036, n=10). The pharmacokinetics data show that both formulations deliver effective amounts of drug into the intraocular tissues, with irbesartan and candesartan reaching concentrations of 121±69 and 30.43±13.93ng/g (mean±SD), respectively, in the aqueous humour 3hr after a single-dose administration.

Topical application of irbesartan and candesartan eye drops delivers effective drug concentrations to the anterior segment of the eye in rabbits, achieving drug concentrations 100 times above the IC50 for angiotensin II receptor and showing an IOP-lowering effect. Angiotensin receptor blocker (ARB) eye drops have potential as a new class of glaucoma drugs.

Here, the emergence and tuning of topological Hall effect (THE) from a CaMnO3 /CaIrO3 /CaMnO3 trilayer structure are studied in detail, which suggests the presence of magnetic Skyrmion-like bubbles. First, by tilting the magnetic field direction, the evolution of the Hall signal suggests a transformation of Skyrmions into topologically-trivial stripe domains, consistent with behaviors predicted by micromagnetic simulations. Second, by varying the thickness of CaMnO3 , the optimal thicknesses for the THE signal emergence are found, which allow identification of the source of Dzyaloshinskii-Moriya interaction (DMI) and its competition with antiferromagnetic superexchange. Employing high-resolution transmission electron microscopy, randomly distributed stacking faults are identified only at the bottom interface and may avoid mutual cancellation of DMI. Last, a spin-transfer torque experiment also reveals a low threshold current density of ≈109 A m-2 for initiating the bubbles’ motion. This discovery sheds light on a possible strategy for integrating Skyrmions with antiferromagnetic spintronics.

To clarify the incidence of lymphatic drainage disorders (LLD) after treatment for cervical cancer (CC) and to establish univariate models for their occurrence.

A total of 263 eligible patients with CC were identified between 2010 and 2019. We conducted a case-control study and divided the study population into two subsamples of 12 and 251 CC survivors based on the presence/absence of LLD, respectively. The cumulative incidence was evaluated using the Kaplan-Meier method. Univariate models based on Pearson correlation coefficient were used to evaluate associations between explanatory variables and LLD.

The cumulative incidence of LLD began at 3.3% after the 7-month follow-up, reaching a plateau of 21.2% between 130 and 250 months of follow-up. We detected correlation between LLD and number of removed para-aortic lymph nodes (r = -0.39), number of pelvic lymphadenopathies (r = 0.16), pelvic lymphadenectomy (PL) (r = 0.16), age at diagnosis of CC (r = -0.1) and primary surgery (r = 0.1).

We observed a cumulative incidence of LLD of 21.2%, which is in accord with other retrospective studies. Number of removed para-aortic lymph nodes, number of pelvic lymphadenopathies, PL, age at diagnosis of CC and primary surgery were the most influential clinical factors associated with the occurrence of LLD in CC survivors.

MSA-2 solubility dmso However, the expression and role of HN1L in breast cancer remain to be investigated. Here, bioinformatics, western blot and immunohistochemistry were used to detect the expression of HN1L in breast cancer. Wound healing, transwell assay, immunofluorescence assay and mass spectrum were used to explore the role and mechanism of HN1L on the migration and invasion of breast cancer, which was confirmed in vivo using a nude mice model. Results showed that HN1L was significantly over-expressed in breast cancer tissues, which was positively correlated with M metastasis of breast cancer patients. Silencing HN1L significantly inhibited the invasion and metastasis of breast cancer cells in vitro and lung metastasis in nude mice metastasis model of breast cancer. Mechanistically, HN1L interacted with HSPA9 and affected the expression of HMGB1, playing a key role in promoting the invasion and metastasis of breast cancer cell.
