A portable optical detection system for rapid quantification of two rheumatoid arthritis biomarkers.

Background: Rheumatoid arthritis (RA) is a chronic autoimmune disease that causes joint damage and progressive destruction of adjacent cartilage and bones. Quick and accurate detection of rheumatoid factors (RF) and anti-cyclic citrullinated peptide antibodies (anti-CCP) in serum is effective in diagnosing RA and preventing its progression. However, current methods for detecting these two biomarkers are costly, time-consuming, labor-intensive, and require specialized equipment.

Chlorophyllides repress gain-of-function p53 mutated HNSCC cell proliferation via activation of p73 and repression of p53 aggregation in vitro and in vivo.

Head and neck squamous cell carcinoma (HNSCC) cells have a high p53 mutation rate, but there were rare reported about the p53 gain of function through the prion-like aggregated form in p53 mutated HNSCC cells. Thioflavin T (ThT) is used to stain prion-like proteins in cells. Previously, we found that ThT and p53 staining were co-localized in HNSCC cells (Detroit 562 cells) with homozygous p53 R175H mutation.

Telocinobufagin suppresses malignant metastasis of undifferentiated thyroid carcinoma via modulation of the LARP1-mTOR pathway.

Metastasis is the trigger of death in anaplastic thyroid cancer (ATC) patients, yet the specific mechanisms at play are still largely enigmatic. While the involvement of LARP1 in the metastatic process of various cancers has been documented, there is a noticeable gap in the literature regarding its potential influence on ATC metastasis. Molecular studies probed LARP1 expression within ATC cells, with subsequent in vitro experiments examining the effects of LARP1 on ATC cell metastasis and the mTOR signaling cascade.

Hyperbaric oxygen therapy attenuates brain radiation-induced cognitive deficits in rats.

Effective therapies for cognitive impairments induced by brain irradiation are currently lacking. This study investigated the therapeutic potential of hyperbaric oxygen therapy (HBOT) for radiation-induced brain injury in a randomized controlled experimental model using adult male Wistar rats. Adult male Wistar rats were divided into four experimental groups: 0 Gy whole brain radiotherapy (WBRT) with normal baric air (NBA) treatment, 0 Gy WBRT with HBOT, 10 Gy WBRT with NBA, and 10 Gy WBRT with HBOT.

Delayed open-heart operation to remove migrated intracardiac inferior vena cava stents in a living donor liver transplantation recipient: a case report.

Intracardiac migration of inferior vena cava (IVC) filter or stent is a rare but potentially fatal complication of endovascular venous device placement. There is no consensus whether migrated stents should be surgically removed by open cardiac surgery or retrieved by the percutaneous endovascular route and whether an intervention should be performed immediately or expectantly. Herein, we report a 39-year-old female who received emergent left lobe living donor liver transplantation (LDLT) owing to posthepatectomy liver failure.

Distal augmentation in unstable distal clavicle fractures: a retrospective cohort study of 101 cases.

Introduction: The optimal management strategy for unstable distal clavicular fractures remains controversial. Recent studies on plate techniques have reported good-to-excellent outcomes with no serious complications. The questions are that: (1) Does the use of wire augmentation with locking plate in distal part (distal wire augmentation) reduce radiographic loss of reduction (RLOR) and get earlier bony union in distal clavicular fractures? (2) Which fixation methods are associated with a higher incidence of acromioclavicular (AC) joints arthritis or subluxation? We collected and analyzed clinical studies on different plate fixation methods for unstable fractures to identify the best surgical modality.
