Long-term zinc treatment alters the mechanical properties and metabolism of prostate cancer cells.

The failure of intracellular zinc accumulation is a key process in prostate carcinogenesis. Although prostate cancer cells can accumulate zinc after long-term exposure, chronic zinc oversupply may accelerate prostate carcinogenesis or chemoresistance. Because cancer progression is associated with energetically demanding cytoskeletal rearrangements, we investigated the effect of long-term zinc presence on biophysical parameters, ATP production, and EMT characteristics of two prostate cancer cell lines (PC-3, 22Rv1).

Logistic regression analysis and machine learning for predicting post-stroke gait independence: a retrospective study.

This study investigated whether machine learning (ML) has better predictive accuracy than logistic regression analysis (LR) for gait independence at discharge in subacute stroke patients (n = 843) who could not walk independently at admission. We developed prediction models using LR and five ML algorithms-specifically, the decision tree (DT), support vector machine, artificial neural network, ensemble learning, and k-nearest neighbor methods. Functional Independence Measure sub-items were used to evaluate the ability to walk independently.

Levodopa-resistant parkinsonism developing after ventriculoperitoneal shunting for obstructive hydrocephalus and improving after endoscopic third ventriculostomy, with specific consideration of brainstem morphology: illustrative case.

Background: Parkinsonism has been reported in patients with obstructive hydrocephalus (OH) following ventriculoperitoneal shunting (VPS). While levodopa works well, some cases are drug resistant. A few case series have reported that endoscopic third ventriculostomy (ETV) is beneficial, though its mechanism remains unclear.

Prior coronary stent does not exclude major pulmonary resection regardless of antiplatelet therapy.

Purpose: We assessed the safety of general thoracic surgery in patients with prior coronary stents undergoing lung resection, based on differences in perioperative antiplatelet therapy management.

Methods: We retrospectively examined 150 patients with coronary artery stents who underwent pulmonary resection between July 2009 and July 2018. The impact of the antiplatelet agent on thoracic surgery safety was assessed by comparing perioperative outcomes, including major adverse cardiac and cerebrovascular events, among the discontinued antiplatelet therapy (group D), heparin bridging (group H), and continuous antiplatelet therapy (group C) groups.

Implementation of an Electronic Medical Record Alert Significantly Increases Lung Cancer Screening Uptake.

Introduction: Lung cancer survival is significantly improved with early detection. However, lung cancer screening (LCS) uptake remains low despite national recommendations. Our aim was to determine whether implementation of an electronic medical record (EMR) alert and order set would increase LCS uptake.

Relationship Between Calcified Plaque Burden, Vascular Inflammation, and Plaque Vulnerability in Patients With Coronary Atherosclerosis.

Background: Coronary artery calcification is an integral part of atherosclerosis. It has been suggested that early coronary artery calcification is associated with active inflammation, and advanced calcification forms as inflammation subsides. Inflammation is also an important factor in plaque vulnerability.

Luminal progenitor and mature cells are more susceptible than basal cells to radiation-induced DNA double-strand breaks in rat mammary tissue.

Ionizing radiation promotes mammary carcinogenesis. Induction of DNA double-strand breaks (DSBs) is the initial event after radiation exposure, which can potentially lead to carcinogenesis, but the dynamics of DSB induction and repair are not well understood at the tissue level. In this study, we used female rats, which have been recognized as a useful experimental model for studying radiation effects on the mammary gland.

Transesophageal ultrasound-guided bronchoscopic Acquire TBNB versus Vizishot2 TBNA needles for neoplastic lesions: A retrospective study.

Background: Lung cancer is often diagnosed at an advanced stage; however, it has shown improved therapeutic efficacy with the introduction of molecularly targeted drugs and immune checkpoint inhibitors, necessitating accurate molecular diagnosis for effective treatment planning. Traditional sampling techniques, including endobronchial ultrasound-guided transbronchial needle aspiration, frequently require multiple biopsies to obtain sufficient tissues for multiplex testing, highlighting the need for more efficient methods. Therefore, we explored the diagnostic utility of endoscopic ultrasound with bronchoscope-guided fine-needle biopsy (EUS-B-FNB) versus fine-needle aspiration (EUS-B-FNA) in patients with lung cancer, focusing on tissue sample collection for molecular testing.

Parameters of 150 temperate and boreal tree species and provenances for an individual-based forest landscape and disturbance model.

Understanding the impacts of changing climate and disturbance regimes on forest ecosystems is greatly aided by the use of process-based models. Such models simulate processes based on first principles of ecology, which requires parameterization. Parameterization is an important step in model development and application, defining the characteristics of trees and their responses to the environment, i.

Anti-Müllerian hormone type II receptor protein expression in non-small cell lung cancer and the effect of AMH/AMHR2 signaling on cancer cell proliferation.

Background: Non-small cell lung cancer (NSCLC) is the leading cause of cancer-related deaths worldwide despite advances in cancer therapeutics. In several gynecological cancers, anti-Müllerian hormone receptor type 2 (AMHR2) mediates AMH-induced growth inhibition and is expressed at high levels. Furthermore, 5%-8% of NSCLCs exhibit high AMHR2 expression, suggesting that AMH may inhibit the progression of some lung cancers.

Splenic abscess caused by successfully managed with percutaneous drainage and antibiotics: A case report.

A 29-year-old man with diabetic nephropathy presented with fever and chills 4 days postdischarge following hospitalization for hyperglycemia. Abdominal computed tomography revealed a splenic abscess. Percutaneous drainage was performed, and intravenous meropenem was administered.

Long-lasting pure topographical disorientation due to heading disorientation following left retrosplenial infarction: A report of two cases.

Topographical disorientation is linked to lesions in the right hemisphere and typically resolves within a few months post-stroke. Persistent topographical disorientation is uncommon and frequently accompanied by impairments in visual memory, complicating the analysis of the underlying mechanisms. Herein, we report two cases of sustained pure topographical disorientation following cerebral hemorrhages in the left retrosplenial region.

Preservation of functionality, immunophenotype, and recovery of HIV RNA from PBMCs cryopreserved for more than 20 years.

Background: Many research laboratories have long-term repositories of cryopreserved peripheral blood mononuclear cells (PBMC), which are costly to maintain but are of uncertain utility for immunological studies after decades in storage. This study investigated preservation of cell surface phenotypes and functional capacity of PBMC from viraemic HIV+ patients and healthy seronegative control subjects, after more than 20 years of cryopreservation.

Methods: PBMC were assessed by 18-colour flow cytometry for major lymphocyte subsets within T, B, NK, and dendritic cells and monocytes.

Effectiveness and outcomes of endoscopic resection for superficial pharyngeal squamous cell carcinomas.

Background: With the development of endoscopic imaging, superficial pharyngeal squamous cell carcinoma can now be detected during routine endoscopy. Recently, the effectiveness of endoscopic resection for superficial pharyngeal squamous cell carcinoma have been reported.

Methods: This study had a retrospective single-center design that included patients with superficial pharyngeal squamous cell carcinoma who underwent endoscopic resection.

Applications of the Third-Generation DNA Sequencing Technology to the Identification of Spoilage Microorganisms in the Brewing Industry.

A new nanopore sequencing-based method has been developed for the detection and identification of a wider range of microorganisms. This method uses universal primers to identify virtually all the bacterial or yeast/fungal species via the amplification and nucleotide sequencing of common ribosomal DNA regions. The simplicity of its protocol makes the method suitable for both small and large breweries.

Simultaneous Necking and Barreling Deformation Behaviors in Bending of Single-Crystal Gold Micro-Cantilever.

Necking and barreling deformation behaviors occurred simultaneously during the bending test of a single-crystal gold micro-cantilever (sample A) with the loading direction parallel to the [1-10] orientation and the neutral plane parallel to the [110] orientation. In contrast, for another single-crystal gold micro-cantilever, sample B, with the loading direction aligned parallel to the [0.37 -0.

A Novel Technique for Corneal Transepithelial Electrical Resistance Measurement in Mice.

We developed a technique that can measure corneal transepithelial electrical resistance (TER) in mice, which was used for evaluating corneal toxicity induced by ophthalmic drugs. We used a tissue culture well and its insert to mount the mouse globe and separated the cornea from the rest of the globe to enable corneal TER measurements to be taken. The explanted mouse eyes were divided into groups, and the corneal epithelia were exposed to different concentrations of BAC.

Identification of Nonsynonymous SNPs in Immune-Related Genes Associated with Pneumonia Severity in Pigs.

We previously showed that several polymorphisms in genes encoding pattern recognition receptors that cause amino acid substitutions alter pathogen recognition ability and disease susceptibility in pigs. In this study, we expanded our analysis to a wide range of immune-related genes and investigated polymorphism distribution and its influence on pneumonia in multiple commercial pig populations. Among the polymorphisms in 42 genes causing 634 amino acid substitutions extracted from the swine genome database, 80 in 24 genes were found to have a minor allele frequency of at least 10% in Japanese breeding stock pigs via targeted resequencing.
