Accumulation of GSK-3β in Interneurons Impairs Adult Hippocampal Neurogenesis by Inhibiting GABAergic Transmission.

The activation of glycogen synthase kinase 3β (GSK-3β) and the deterioration of spatial memory represent prominent pathological and clinical manifestations of Alzheimer's disease (AD). Nevertheless, the precise intrinsic mechanisms linking these pathological features remain poorly elucidated. In this study, we identified significant upregulation of GSK-3β activity in inhibitory interneurons within the hippocampal dentate gyrus (DG) of 3×Tg-AD mice.

Ultrasonic features of automated breast volume scanner (ABVS) and handheld ultrasound (HHUS) combined with molecular biomarkers in predicting axillary lymph node metastasis of clinical T1-T2 breast cancer.

Background: In the post-American College of Surgeons Oncology Group Z0011 trial era, clinicians are attempting to preoperatively evaluate axillary lymph node (ALN) status using ultrasound. However, the value of preoperative ultrasound examination remains uncertain. The study aimed to investigate the ultrasonic features of automated breast volume scanner (ABVS) and handheld ultrasound (HHUS), in combination with molecular biomarkers, to predict the risk of ALN metastasis (ALNM) in clinical T1-T2 breast cancer.

[Erratum] Oxidative stress, autophagy and pyroptosis in the neovascularization of oxygen‑induced retinopathy in mice.

Subsequently to the publication of this paper, the authors have realized that Figs. 2 and 5 have been published containing the same GAPDH control protein bands. After having examined the final proofs of this article, the control blots were indeed different comparing between the figures, and regrettably an error concerning Fig.

Tanshinone IIA Suppresses Hypoxia-induced Apoptosis in Medial Vestibular Nucleus Cells a Skp2/BKCa Axis.

Background: The aim of the present study was to investigate the protective effects of Tanshinone IIA (Tan IIA) on hypoxia-induced injury in the medial vestibular nucleus (MVN) cells.

Methods: An in vitro hypoxia model was established using MVN cells exposed to hypoxia. The hypoxia-induced cell damage was confirmed by assessing cell viability, apoptosis and expression of apoptosis-associated proteins.

Ablation of Immunoproteasome β5i Subunit Suppresses Hypertensive Retinopathy by Blocking ATRAP Degradation in Mice.

Inflammation is associated with retinal diseases. Our recent data demonstrate that immunoproteasome catalytic subunit β2i contributes to angiotensin II (Ang II)-induced retinopathy in mice. Here, we investigated the role of another catalytic subunit β5i in regulating retinopathy and its underlying mechanisms.

Oxidative stress, autophagy and pyroptosis in the neovascularization of oxygen‑induced retinopathy in mice.

Retinal neovascularization (RNV) is a principal cause of visual impairment and blindness worldwide. The present study aimed to investigate how oxidative stress, autophagy and pyroptosis alter in RNV. The oxygen‑induced retinopathy (OIR) model was established in C57BL/6J mice by exposing them to a high concentration of oxygen.

Cytotoxic effect of interleukin-8 in retinal ganglion cells and its possible mechanisms.

Aim: To investigate the effect of interleukin-8 (IL-8) on neural retinal ganglion cells (RGCs) and whether it can be alleviated by G31P.

Methods: RGC-5 cells were exposed to IL-8 with or without its specific receptor antagonist G31P for 24h, and the cell viability was assessed by Cell Counting Kit 8 (CCK-8). Apoptosis was measured by examining nuclear morphology and quantifying with flow cytometry.

Dihydroartemisinin alleviates oxidative stress in bleomycin-induced pulmonary fibrosis.

Aims: Dihydroartemisinin has been shown to inhibit the development of pulmonary fibrosis in rats, but its mechanism has yet to be elucidated. This study aimed to determine the mechanisms of dihydroartemisinin in bleomycin-induced pulmonary fibrosis in a rat model.

Main Methods: Morphological changes and collagen deposition were analyzed via hematoxylin-eosin staining and Masson staining and the expression of biotic-factor-related oxidative stress in lung tissues was assayed with standard assay kits.

The immunoproteasome subunit LMP10 mediates angiotensin II-induced retinopathy in mice.

Inflammation has been implicated in a variety of retinal diseases. The immunoproteasome plays a critical role in controlling inflammatory responses, but whether activation of immunoproteasome contributes to angiotensin II (Ang II)-induced retinopathy remains unclear. Hypertensive retinopathy (HR) was induced by infusion of Ang II (3000 ng/kg/min) in wild-type (WT) and immunoproteasome subunit LMP10 knockout (KO) mice for 3 weeks.

[Comparison of the clinical effects of selective laser melting deposition basal crowns and cobalt chromium alloy base crowns].

Purpose: To evaluate the clinical effects of selective laser melting (SLM) deposition basal crowns and cobalt chromium alloy casting base crowns.

Methods: One hundred and sixty eight patients treated with either SLM deposition basal crowns (110 teeth) or cobalt chromium alloy casting basal crowns (110 teeth) were followed-up for 1 month, 6 months, 12 months and 24 months. The revised standard of American Public Health Association was used to evaluate the clinical effect of restoration, including the color of porcelain crowns, gingival inflammation, gingival margin discoloration, and crack or fracture.

Oral malignant acanthosis nigricans associated with endometrial adenocarcinoma.

We report a 59-year-old patient with malignant acanthosis nigricans associated with metastasis of endometrial carcinoma. The patient presented papillomatosis lesions that appeared to be benign on multiple skins of body folds, particularly on lips. The lesions in lips and axilla had histological characteristic appearances of acanthosis nigricans, while the masses in abdomen and pelvis were metastasis endometrial adenocarcinoma.

Microchannel refill: a new method for fabricating 2D nanochannels in polymer substrates.

In this paper, we present a new approach that is capable of fabricating nanochannels in a poly(methyl methacrylate) (PMMA) substrate. This method, which we call microchannel refill (MR), utilizes the refilling of glassy thermoplastics under thermal compression to reduce a microscopic channel to a nanochannel. It only has two main steps.

Chemoresistance to temozolomide in human glioma cell line U251 is associated with increased activity of O6-methylguanine-DNA methyltransferase and can be overcome by metronomic temozolomide regimen.

Temozolomide (TMZ) is a novel cytotoxic alkylating agent for chemotherapy of malignant gliomas. However, intrinsic or acquired resistance to TMZ often defines poor efficacy of chemotherapy in malignant gliomas. A growing number of studies indicate that expression of O(6)-methylguanine-DNA methyltransferase (MGMT) is one of the principal mechanisms responsible for this chemoresistance.

A bio-inspired micropump based on stomatal transpiration in plants.

Stomatal transpiration, which is an efficient way to carry water from the roots up to the leaves, can be described by "diameter-law". According to the law, the flow rate induced by micropore transpiration far exceeded that induced by macroscale evaporation, and it can be controlled by opening (or closing) some micropores. In this research, a bio-inspired micropump based on stomatal transpiration is presented.

Fracture mechanism of metal electrode integrated on a chip and fabrication of a poly(ethylene terephthalate) electrophoresis microchip.

Thermal bonding is an important technique to fabricate polymer electrophoresis microchip. However, the metal electrodes deposited on polymer substrate can readily fracture during the thermal bonding. In this paper, poly(ethylene terephthalate) (PET) was exploited to fabricate the electrophoresis microchip with an integrated gold electrode for amperometric detection.

The promoting angiogenesis and anti-inflammation effect of scutellarin on polyglycolic acid scaffold of balb/c mice model.

Engineering artificial implantable tissues require rapid induction of angiogenesis to meet the significant oxygen and nutrient demands of the cell during tissue repair. In this study, we investigated the role of a Chinese medicine, scutellarin (1), in the tissue engineering scaffold of balb/c mice model. The trial groups of balb/c mice were given an intraperitoneal injection of 1 at 20, 60, and 100 mg/kg per ml, respectively.
