Article Synopsis
  • The study aimed to analyze the histological features of vocal folds in rats at various ages, focusing particularly on older rats.
  • Researchers used different age groups of Sprague-Dawley rats and employed immunohistochemistry and staining techniques to assess cell proliferation and analyze collagen and elastin levels.
  • Findings indicated that older rats showed an increase in collagen fibers and a decrease in elastin, with significant proliferation of specific cell types, suggesting age-related changes in vocal fold structure that may have relevance to human vocal health.

Surface atom diffusion is a ubiquitous phenomenon in nanostructured metals with ultrahigh surface-to-volume ratios. However, the fundamental atomic mechanism of surface atom diffusion remains elusive. Here, we report in situ atomic-scale observations of surface pressure-driven atom diffusion in gold nanocrystals at room temperature using high-resolution transmission electron microscopy with a high-speed detection camera.

Background: Eustachian tube dysfunction (ETD) is the predominant cause of otitis media with effusion in children and adults. Balloon dilatation of the Eustachian tube (BDET) provides a new method for restoring the ventilatory function of Eustachian tube (ET). However, the differences in age-related morphological changes in the dimensions and positions of ET in children and adults are unclear.

Objective: The distribution and role of NMDA receptors is unclear in the afferent signaling complex of the cochlea. The present study aimed to examine the distribution of NMDA receptors in cochlear afferent signaling complex of the adult mouse, and their relationship with ribbon synapses of inner hair cells (IHCs) and GABAergic efferent terminals of the lateral olivocochlear (LOC).

Methods: Immunofluorescence staining in combination with confocal microscopy was used to investigate the distribution of glutamatergic NMDA and AMPA receptors in afferent terminals of SGNs, and their relationship with ribbon synapses of IHCs and GABAergic efferent terminals of LOC.

Purpose: The drug resistance and low response rates of immunotherapy limit its application. This study aimed to construct a new nanoparticle (CaCO-polydopamine-polyethylenimine, CPP) to effectively deliver interleukin-12 (IL-12) and suppress cancer progress through immunotherapy.

Methods: The size distribution of CPP and its zeta potential were measured using a Malvern Zetasizer Nano-ZS90.

Background And Aims: Duodenal perforation caused by foreign bodies (FBs) is very rare but is an urgent emergency that traditionally requires surgical intervention. Several case reports have reported the successful endoscopic removal of duodenal perforating FBs. Here we aimed to evaluate the safety and efficacy of endoscopic management of duodenal perforating FBs in adults.

To investigate the clinical characteristics and surgical treatment outcomes of children with cervical bronchogenic cysts. A retrospective study of 6 pediatric patients with bronchogenic cysts in the neck region treated in our hospital during 2014 to 2020 was performed. All children underwent complete resection of cervical mass under general anesthesia.

Introduction: As the special modality of cell death, immunogenic cell death (ICD) could activate immune response. Phototherapy in combination with chemotherapy (CT) is a particularly efficient tumor ICD inducing method that could overcome the defects of monotherapies.

Methods: In this study, new dual stimuli-responsive micelles were designed and prepared for imaging-guided mitochondrion-targeted photothermal/photodynamic/CT combination therapy through inducing ICD.

This study aimed to assess the efficacy of hepatocyte growth factor (HGF)-transfected adipose-derived mesenchymal stem cell (ADSC) transplantation in the injured vocal folds (VFs) of canines. A lentiviral vector encoding HGF was successfully produced via Gateway cloning, which was used to infect ADSCs. Four weeks after transoral laser microsurgery (type II) with CO laser, the beagles of each group were injected with HGF-transfected ADSCs or uninfected ADSCs into VFs.

Transthyrohyoid access to the larynx for endoscopic resection (TTER) for early-stage glottic cancer in patients with difficult laryngeal exposure (DLE) has recently been developed. However, little is known about the postoperative conditions of patients. Twelve early-stage glottic cancer patients with DLE who received TTER were retrospectively reviewed.

Background: MicroRNAs (miRNAs) play crucial roles in the development of various cancers. Here, we aimed to evaluate the roles of miR-138-5p in lung cancer progression and the value of miR-138-5p in lung cancer diagnosis.

Methods: Quantitative real-time PCR was performed to examine the expressions of miR-138-5p and smad nuclear interacting protein 1 (SNIP1) mRNA.

Reduced drug uptake and elevated drug efflux are two major mechanisms in cancer multidrug resistance (MDR). In the present study, a new multistage O-producing liposome with NAG/R8-dual-ligand and stimuli-responsive dePEGylation was developed to address the abovementioned issues simultaneously. The designed C-NAG-R8-PTXL/MnO-lip could also achieve magnetic resonance imaging (MRI)-guided synergistic chemodynamic/chemotherapy (CDT/CT).

The construction of high-efficiency tumor theranostic platform will be of great interest in the treatment of cancer patients; however, significant challenges are associated with developing such a platform. In this study, we developed high-efficiency nanotheranostic agent based on ferroferric oxide, manganese dioxide, hyaluronic acid and doxorubicin (FMDH-D NPs) for dual targeting and imaging guided synergetic photothermal-enhanced chemodynamic/chemotherapy for cancer, which improved the specific uptake of drugs at tumor site by the dual action of CD44 ligand hyaluronic acid and magnetic nanoparticles guided by magnetic force. Under the acidic microenvironment of cancer cells, FMDH-D could be decomposed into Mn and Fe to generate •OH radicals by triggering a Fenton-like reaction and responsively releasing doxorubicin to kill cancer cells.

Chronic myeloid leukemia (CML) is a hematological disease, and imatinib (IM) resistance represents a major problem for its clinical treatment. In the present study, the role of tribbles pseudokinase 2 (TRIB2) in IM resistance of CML and the possible mechanism were investigated. It was found that TRIB2 was highly expressed in IM‑resistant patients with CML through the Oncomine database and this conclusion was confirmed using reverse transcription‑quantitative PCR and western blot experiments.

Gastric cancer is a type of cancer that is characterized by high morbidity and mortality rates. Long non-coding RNA (lncRNA) β-1,3-galactosyltransferase 5-AS1 (B3GALT5-AS1) was previously found to be highly expressed in the serum of patients with gastric cancer. However, the regulatory effects of B3GALT5-AS1 in gastric cancer remain poorly understood.

Non-coding RNAs (ncRNAs) involve in diverse biological processes by post-transcriptional regulation of gene expression. Emerging evidence shows that miRNA-4293 plays a significant role in the development of non-small cell lung cancer. However, the oncogenic functions of miR-4293 have not been studied.
