Serum TARC Level as a Predictive Marker of Severe Disease in COVID-19 During the Omicron Variant Period of the Pandemic.

Objectives Thymus and activation-regulated chemokine (TARC) can predict severe disease in patients with coronavirus disease 2019 (COVID-19). However, no reports have addressed the predictive value of TARC with the widespread use of vaccines and medications for COVID-19 during the Omicron variant period of the pandemic. Methods This single-center prospective cohort study enrolled COVID-19 patients admitted to our institution between December 1, 2021, and August 15, 2022.

Analysis of immune checkpoint inhibitors for advanced non-small cell lung cancer in patients receiving antacids.

Background: Proton pump inhibitors (PPIs) are reported to decrease the efficacy of immune checkpoint inhibitors (ICIs), but there are few reports on the association between ICI efficacy and antacids other than PPIs, and simultaneous examination of the effects of antacids, corticosteroids, and non-steroidal anti-inflammatory drugs (NSAIDs) on ICI therapy.

Methods: We conducted a retrospective study of 381 patients with non-small cell lung cancer who received ICI therapy from January 1, 2016 to December 31, 2022. The primary endpoint was overall survival (OS) and the secondary endpoint was progression-free survival (PFS).

Embryonic stem cells maintain high origin activity and slow forks to coordinate replication with cell cycle progression.

Embryonic stem (ES) cells are pluripotent stem cells that can produce all cell types of an organism. ES cells proliferate rapidly and are thought to experience high levels of intrinsic replication stress. Here, by investigating replication fork dynamics in substages of S phase, we show that mammalian pluripotent stem cells maintain a slow fork speed and high active origin density throughout the S phase, with little sign of fork pausing.

Ferromagnetic Fluctuations in the Heavily Overdoped Regime of Single-Layer High- Cuprate Superconductors.

To investigate proposed ferromagnetic fluctuations in the so-called single-layer Bi-2201 and La-214 high- cuprates, we performed magnetization and electrical resistivity measurements using single-layer Tl-2201 cuprates TlBaCuO and La-214 LaSrCuO in the heavily overdoped regime. Magnetization of TlBaCuO and LaSrCuO exhibited the tendency to be saturated in high magnetic fields at low temperatures, suggesting the precursor behavior toward the formation of a ferromagnetic order. It was found that the power of temperature obtained from the temperature dependence of the electrical resistivity is ~4/3 and ~5/3 for Bi-2201 and LaSrCuO, respectively, and is ~4/3 at high temperatures and ~5/3 at low temperatures in TlBaCuO.

Cancer Stem Cells of Hepatocellular Carcinoma Are Suppressed by the Voltage-gated Calcium Channel Inhibitor Amlodipine.

Background/aim: The membrane transporters activated in cancer stem cells (CSCs) are the target of novel cancer therapies for hepatocellular carcinoma (HCC). The present investigation demonstrated the expression profiles of ion channels in CSCs of HCC.

Materials And Methods: Cells that highly expressed aldehyde dehydrogenase 1 family member A1 (ALDH1A1) were separated from HepG2 cells, a human HCC cell line, by fluorescence-activated cell sorting, and CSCs were identified based on the formation of tumorspheres.

Normothermic ex vivo perfusion of deceased donor kidneys and its clinical potential in kidney transplantation outcomes.

In recent years, normothermic machine perfusion (NMP) has emerged in conversation surrounding organ preservation and transplantation techniques with the goal of improving patient and clinical outcomes. This is in great attempt to address the rate of non-utilization and the shortage of available organs in kidney transplantation. This focus in mind, normothermic perfusion presents itself as a potential tool to mimic physiological conditions and improve current preservation methods, such as static cold storage.

Findings from a discontinued clinical trial of favipiravir in high-risk patients with early-onset COVID-19.

Introduction: Favipiravir terminates severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) replication. Accordingly, early administration of favipiravir to SARS-CoV-2-infected coronavirus disease 2019 (COVID-19) patients may be expected to suppress disease progression.

Methods: A randomized double-blind placebo-controlled trial was conducted to demonstrate efficacy of favipiravir in reducing disease progression in patients with mild COVID-19.

The Effects of Utilizing Cartilage Conduction Hearing Aids among Patients with Conductive Hearing Loss.

The cartilage-conduction hearing aid (CC-HA) is a new hearing device that is suitable for use in patients with conductive hearing loss. It has been 5 years since the introduction of the CC-HA. Although the number of users has increased, the CC-HA is not yet widely known.

Gut Microbiota Modulation of Short Bowel Syndrome and the Gut-Brain Axis.

Short bowel syndrome (SBS) is a condition that results from a reduction in the length of the intestine or its functional capacity. SBS patients can have significant side effects and complications, the etiology of which remains ill-defined. Thus, facilitating intestinal adaptation in SBS remains a major research focus.

Development of Magnetocardiograph without Magnetically Shielded Room Using High-Detectivity TMR Sensors.

A magnetocardiograph that enables the clear observation of heart magnetic field mappings without magnetically shielded rooms at room temperatures has been successfully manufactured. Compared to widespread electrocardiographs, magnetocardiographs commonly have a higher spatial resolution, which is expected to lead to early diagnoses of ischemic heart disease and high diagnostic accuracy of ventricular arrhythmia, which involves the risk of sudden death. However, as the conventional superconducting quantum interference device (SQUID) magnetocardiographs require large magnetically shielded rooms and huge running costs to cool the SQUID sensors, magnetocardiography is still unfamiliar technology.

Novel Therapeutic Approaches for Mitigating Complications in Short Bowel Syndrome.

Short bowel syndrome (SBS) is a particularly serious condition in which the small intestine does not absorb sufficient nutrients for biological needs, resulting in severe illness and potentially death if not treated. Given the important role of the gut in many signaling cascades throughout the body, SBS results in disruption of many pathways and imbalances in various hormones. Due to the inability to meet sufficient nutritional needs, an intravenous form of nutrition, total parental nutrition (TPN), is administered.

Antibody titers among healthcare workers for coronavirus disease 2019 at 6 months after BNT162b2 vaccination.

Background: Antibody levels decrease substantially at 6 months after the BNT162b2 vaccine. The factors influencing titer of antibodies against severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) among healthcare workers for coronavirus disease 2019 (COVID-19) is unclear.

Methods: We conducted a 6-month longitudinal prospective study in Japanese healthcare workers in a tertiary care hospital for COVID-19.

Roles of voltage‑gated potassium channels in the maintenance of pancreatic cancer stem cells.

The targeting of membrane proteins that are activated in cancer stem cells (CSCs) represents one of the key recent strategies in cancer therapy. The present study analyzed ion channel expression profiles and functions in pancreatic CSCs (PCSCs). Cells strongly expressing aldehyde dehydrogenase 1 family member A1 (ALDH1A1) were isolated from the human pancreatic PK59 cell line using fluorescence‑activated cell sorting, and PCSCs were identified based on tumorsphere formation.

LRRC8A influences the growth of gastric cancer cells via the p53 signaling pathway.

Background: Leucin-rich repeat containing protein A (LRRC8A), a component of the volume-regulated anion channel (VRAC), is activated by cell swelling and mediates regulatory volume decrease. We previously reported the expression of and important roles for several ion transporters in various gastrointestinal cancers, which have potential as novel targets for cancer treatment; however, the significance of LRRC8A in gastric cancer (GC) remains unclear.

Materials And Methods: Knockdown experiments were performed by transfecting human GC cell lines with LRRC8A siRNA.

A retrospective analysis of pembrolizumab plus chemotherapy versus pembrolizumab monotherapy for advanced or recurrent non-small cell lung cancer.

Methods: We conducted a retrospective study of 71 NSCLC patients including 33 treated with pembrolizumab plus chemotherapy (combination therapy group) and 38 treated with pembrolizumab monotherapy (monotherapy group) from 1 May 2016 to 31 August 2020.

Results: Eleven of 33 (33.

Outcome and risk factor of immune-related adverse events and pneumonitis in patients with advanced or postoperative recurrent non-small cell lung cancer treated with immune checkpoint inhibitors.

Background: Non-small cell lung cancer (NSCLC) patients with pre-existing respiratory diseases have been excluded in clinical trials of immune checkpoint inhibitor (ICI) therapy, and it is unknown whether the same degree of response can be expected as that in patients without pre-existing respiratory diseases and if they are associated with increased risk for various immune-related adverse events (irAEs) and ICI pneumonitis. This study aimed to evaluate predictive factors of clinical response, prognostic factors, risk factors of irAEs, and ICI pneumonitis in NSCLC patients with or without pre-existing respiratory diseases.

Methods: We conducted a retrospective study of 180 NSCLC patients who received ICI monotherapy of nivolumab, pembrolizumab, or atezolizumab from 1 January 2016 to 31 March 2019.
