Pressure serves as a fundamental tuning parameter capable of drastically modifying all properties of matter. The advent of diamond anvil cells (DACs) has enabled a compact and tabletop platform for generating extreme pressure conditions in laboratory settings. However, the limited spatial dimensions and ultrahigh pressures within these environments present significant challenges for conventional spectroscopy techniques.

Mitochondria are multifunctional organelles that convert the potential energy stored in nutrients and intermediary metabolites into both heat and an electrochemical proton-motive force. However, how these outputs are synchronized in cells remains an enduring question. In this work, leveraging multiplexed nanodiamond quantum sensors to monitor both changes in temperature and magnetic field fluctuations in single primary cells obtained from diverse tissues in adult mice, we identified thermomagnetic correlation profiles uncovering a regulatory feedback loop in which the cell draws upon available intracellular iron to maintain the mitochondrial electrochemical gradient.

Background: Postoperative complications may lower the quality of life of patients, consequently leading to a reduction in their overall survival (OS). In our previous investigations, we found that patients with gastric cancer (GC) with postoperative complications who underwent direct surgery had a significantly lower OS than patients without complications. We observed no significant difference in OS among patients who underwent neoadjuvant chemotherapy (NAC), regardless of complications.

Probing electrical and magnetic properties in aqueous environments remains a frontier challenge in nanoscale sensing. Our inability to do so with quantitative accuracy imposes severe limitations, for example, on our understanding of the ionic environments in a diverse array of systems, ranging from novel materials to the living cell. The Nitrogen-Vacancy (NV) center in fluorescent nanodiamonds (FNDs) has emerged as a good candidate to sense temperature, pH, and the concentration of paramagnetic species at the nanoscale, but comes with several hurdles such as particle-to-particle variation which render calibrated measurements difficult, and the challenge to tightly confine and precisely position sensors in aqueous environment.

To investigate the value of retrograde thyroidectomy from top to bottom in the operation of retrosternal thyroid surgery. Retrospective analysis was performed on the cases of retrosternal goiter excised by our surgeons from January 2017 to June 2022,the technical points, feasibility and advantages of the operation were summarized. A total of 15 cases of retrosternal goiter treated by retrograde thyroidectomy were collected, including 5 cases of type Ⅰ retrosternal goiter and 10 cases of type Ⅱ retrosternal goiter.

Blood-brain barrier (BBB) function deteriorates during aging, contributing to cognitive impairment and neurodegeneration. It is unclear what drives BBB leakage in aging and how it can be prevented. Using single-nucleus transcriptomics, we identified decreased connexin 43 (CX43) expression in cadherin-5 (Cdh5) cerebral vascular cells in naturally aging mice and confirmed it in human brain samples.

Hepatocellular carcinoma (HCC) is the fourth leading cause of cancer-associated death worldwide. Angiogenesis, the process of formation of new blood vessels, is required for cancer cells to obtain nutrients and oxygen. HCC is a typical hypervascular solid tumor with an aberrant vascular network and angiogenesis that contribute to its growth, progression, invasion, and metastasis.

Hepatocellular carcinoma (HCC) remains an important disease for health care systems in view of its high morbidity, mortality, and increasing incidence worldwide. Radiofrequency ablation (RFA) is preferred to surgery as a local treatment for HCC because it is safer, less traumatic, less painful, better tolerated, causes fewer adverse reactions, and allows more rapid postoperative recovery. The biggest shortcoming of RFA when used to treat HCC is the high incidence of residual tumor, which is often attributed to the vascular thermal deposition effect, the wide infiltration zone of peripheral venules, and the distance between satellite foci and the main focus of the cancer.

Purpose: To determine the efficacy of transcutaneous electrical acupoint stimulation (TEAS) combined with proton pump inhibitor (PPI) therapy on symptoms and signs of patients with suspected laryngopharyngeal reflux disease (LPRD).

Methods: This was a prospective randomized controlled study. Seventy patients with reflux symptom index (RSI) > 13 and reflux finding score (RFS) > 7 were recruited and received PPI alone (control group) or TEAS combined with PPI (experimental group) for 12 weeks.

Background: As one of the most devastating cancers, head and neck squamous cell carcinoma (HNSCC) has a short survival time and poor prognosis. Pescadillo ribosomal biogenesis factor 1 (PES1) plays a critical role in the progression of numerous cancers. However, its role and underlying mechanisms in HNSCC remain unclear.

Epithelial membrane protein (EMP1), a member of the peripheral myelin protein (PMP22) family, is involved in the development of various human malignancies. However, the expression level of EMP1 and its functional role in head and neck squamous cell carcinoma (HNSCC) remain unclear to date. Ferroptosis, a newly characterized form of regulated cell death, plays an essential role in tumorigenesis.

Wallerian degeneration (WD) involves the recruitment of macrophages for debris clearance and nerve regeneration, and the cause of the foamy macrophages that are frequently observed in peripheral transection injuries is unknown. Recent studies indicated that these foamy cells are generated by gasdermin D (GSDMD) via membrane perforation. However, whether these foamy cells are pyroptotic macrophages and whether their cell death elicits immunogenicity in peripheral nerve regeneration (PNR) remain unknown.

Radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC) often leads to aggressive local recurrence and increased metastasis, and vascular integrity and platelets are implicated in tumor metastasis. However, whether interactions between endothelial cells and platelets induce endothelial permeability in HCC after insufficient RFA remains unclear. Here, significantly increased CD62P-positive platelets and sP-selectin in plasma are observed in HCC patients after RFA, and tumor-associated endothelial cells (TAECs) activate platelets and are susceptible to permeability after heat treatment in the presence of platelets in vitro.

To explore the significance of preoperative cervical thoracic enhancement CT and CTA in the selection of different tumor surgical methods at the base of the neck to minimize complications. Analysing the clinical data of 51 patients who had cervical root tumor surgery, including 24 benign lesions and 27 malignant tumors. Enhanced CT and/or CTA examinations were used before surgery to understand the relationship between tumors and/ or recurrent or metastatic lesions and the unnamed arteriovenous, internal jugular arteriovenous, clavicular arteriovenous, thyroid neck, and cone arteries of the cervical root.

Platelets play important roles in tumorigenesis, angiogenesis and metastatic dissemination of tumor cells. Radiofrequency ablation (RFA) could increase the circulating tumor cells in patients with primary or metastatic lung tumors. Whether platelet lysates in hepatocellular carcinoma (HCC) after RFA promote tumor progression has not been elaborated.

Article Synopsis
  • The study aimed to assess vitamin D levels and regulatory T cell frequencies in children undergoing adenotonsillectomies compared to a control group.
  • Results showed that a high percentage of children undergoing T&As were either vitamin D deficient or insufficient, and they also had significantly lower levels of %Tregs compared to controls.
  • The findings indicated that lower vitamin D levels were associated with greater sizes of tonsils and adenoids, as well as higher OSA-18 scores, suggesting a link between vitamin D, Tregs, and adenotonsillar hypertrophy in these children.

Despite its rarity, insulinoma is the most common type of pancreatic endocrine neoplasm, with an occurrence of 1 to 5 per million per year in the population. Surgical resection or enucleation is the first line of curative treatment choice for insulinoma. Eight patients with symptomatic insulinomas treated by radiofrequency ablation have been described since 2009.
