Antitumor immunostimulatory effect via cell-killing action of a novel extracorporeal blood circulating photodynamic therapy system using 5-aminolevulinic acid.

This study investigated whether intravenous administration of tumor cells killed by photodynamic therapy (PDT) with 5-aminolevulinic acid (5-ALA) had antitumor effects on distal tumors. Furthermore, a novel extracorporeal blood circulating 5-ALA/PDT system was developed. 5-ALA/PDT- (low or high irradiation) or anticancer drug-treated cells were intravenously administered to rats in a glioma cancer model.

Cribriform Pattern Is a Predictive Factor of PSA Recurrence in Patients Receiving Radiotherapy After Prostatectomy.

Background/aim: In prostate cancer, robotic total prostatectomy is a popular treatment modality. However, prostate-specific antigen (PSA) recurrence after prostate cancer surgery remains a concern. Salvage radiotherapy is commonly used to treat PSA recurrence, but the recurrence rate after salvage radiotherapy is high, highlighting the need for better predictive markers.

Efficacy of Paclitaxel and Cetuximab in Recurrent/Metastatic Oral Cancer Cases Following Superselective Intraarterial Chemoradiotherapy: A Retrospective Cohort Study.

Background/aim: The therapeutic efficacy of the paclitaxel (PTX) + cetuximab (Cmab) combination regimen was investigated in patients with recurrence or metastasis after superselective intraarterial chemoradiotherapy (SSIACRT) for oral cancer, and the safety was retrospectively examined.

Patients And Methods: All enrolled patients with advanced oral cancer or who had refused surgery over 10 years from December 2012 to December 2022 underwent SSIACRT for 6 to 9 weeks [cisplatin (CDDP): total 160-630 mg/m and radiotherapy: total 50-70 Gy]. Nine cases (tongue cancer, maxillary gingival cancer, and mandibular gingival cancer; three cases each) were subjected to PTX + Cmab therapy.

Safety, pharmacokinetics, and pharmacodynamics of ART-648, a PDE4 inhibitor in healthy subjects: A randomized, placebo-controlled phase I study.

Phosphodiesterase 4 (PDE4) inhibitor is associated with a broad-spectrum anti-inflammatory mechanism. However, securing clinically efficacious doses with sufficient safety margins remains challenging due to class specific adverse events that are often unavoidable in the clinic. ART-648 is an orally available PDE4 inhibitor being developed for the treatment of inflammatory diseases.

Studies on the antifungal effects of Hinokitiol on Candida albicans: inhibition of germ tube formation and synergistic pharmacological effects of miconazole.

One of the goals of oral healthcare management is to manage dry mouth. Thus, moisturizers containing antimicrobial ingredients, such as hinokitiol (HT), are applied to the oral mucosa after oral care. In this study, we investigated the preventive effect of HT against the growth of Candida albicans (C.

Intracellular signaling pathways involved in the regulation of gene expression by pilocarpine.

Objectives: Pilocarpine is commonly used clinically to treat dry mouth. The long-term administration of pilocarpine reportedly improves salivary secretion more effectively than short-term administration. Therefore, we hypothesized that pilocarpine alters gene expression in salivary glands via muscarinic receptor stimulation.

Basal differentiation and expression status of SOX2 and KLF4 in basal layers are prognostic factors for disease-specific survival in oral squamous cell carcinoma.

Background: Basal differentiation in oral squamous cell carcinoma is usually detected at invasive sites. However, its significance as a prognostic value has been poorly investigated.

Methods: COL17 was selected as a basal differentiation marker because of its stable expression in the basal-like cells of oral squamous cell carcinoma.

Three-dimensional sensing of surfaces by projection of invisible electroluminescence from organic light-emitting diodes.

Organic light-emitting diodes (OLEDs) that efficiently emit near-infrared (NIR) light and consume little power will create valuable applications for OLEDs beyond just displays. Here, we report such a NIR-OLED with high operational stability that can be used as a light source for three-dimensional sensing of object's surfaces. Using a narrow-energy-gap material as a host for producing NIR hyperfluorescence system, we fabricated a NIR-OLED exhibiting intense emission at 930 nm with a high external electroluminescence quantum efficiency of more than 1% at a current density of 100 milliamperes per square meter without any degradation even after more than 300 hours of operation.

Relationship between dietary fiber to carbohydrate ratio and mortality risk in US adults: NHANES 2007-2018.

Background And Aims: The evidence is inconsistent regarding associations between relative proportions of macronutrient intake and disease risk, potentially due to limitations in accounting for differential effects of simple sugars and dietary fiber, grouped as "carbohydrates." We examined the association between the ratio of dietary fiber to carbohydrate intake (FC-R) measure, the relative proportion of macronutrients, and mortality risk in a nationally representative sample of U.S.

A case of primary lung adenocarcinoma mimicking metastatic papillary thyroid carcinoma.

A 61-year-old woman, who had a history of total thyroidectomy for follicular variant of papillary thyroid carcinoma (PTC), visited our hospital for assessment of an enlarging nodule which appeared in the lung with multiple metastatic lesions of PTC which had been stable for 17 years. Wedge resection of the lung was performed. Miliary nodules were confirmed to be metastatic PTCs based on their morphological as well as immunohistochemical findings.

Body weight reduction by exercise increases the urinary 3-methylhistidine excretion level with relatively positive nitrogen, sodium, and potassium balances when compared to dietary restriction.

Background: Regarding changes in muscle mass, differences due to types of exercise and/or nutritional interventions, and associations with nutrient balances are still unclear.

Methods: To estimate changes in muscle mass during a body weight loss program using either a diet or exercise regimen, we investigated levels of muscle mass-related indices, and body contents of nitrogen, sodium, and potassium as measured by the balance method. Six healthy young adult male volunteers participated in two 10-day crossover experiments (20 days total).

RNA-binding protein 14 promotes phase separation to sustain prostate specific antigen expression under androgen deprivation in human prostate cancer.

Castration-resistant prostate cancer (CRPC) is a big challenge in managing prostate cancer patients. The androgen receptor (AR) pathway is a major driver even in CRPC under androgen deprivation. The mechanism in maintaining of the AR pathway under androgen deprivation remains elusive.

Sodium Valproate Use in Japanese Patients with Schizophrenia and Coronavirus Disease Is Associated with an Increased Risk of Pneumonia.

Schizophrenia is a known risk factor for coronavirus disease (COVID-19) infection and severity, and certain psychotropic drugs have been linked to increased mortality in infected patients with schizophrenia. However, little evidence exists regarding this risk. We retrospectively examined the association between mood stabilizers and the risk of pneumonia in patients with schizophrenia.

The ECAS system can superselectively administer anticancer drugs to numerous feeding arteries from the superficial temporal artery: A case report and literature review.

Superselective intra-arterial chemoradiotherapy (SSIACRT) is one of the curative treatments for advanced oral cancer. SSIACRT can reportedly treat cervical lymph node metastases in the level I-IIA area by super selectively catheterizing the facial artery (FA) and infusing drugs. However, since advanced oral cancer lesions involve a number of feeding vessels, retrograde treatment requires the placement of catheters from the superficial temporal artery (STA) and occipital artery (OA).

A randomized, placebo-controlled study to evaluate safety and pharmacokinetics of ART-001 with a novel oral pediatric formulation in healthy subjects.

ART-001 is an orally available selective PI3Kα inhibitor currently being developed for the treatment of slow-flow vascular malformations (SFVMs). ART-001 used to be developed for advanced solid tumors, but was suspended largely due to significant pharmacokinetic (PK) variability in its phase I studies. This phase I, randomized, double-blinded, placebo-controlled study evaluated safety, tolerability and PK of ART-001 with a newly developed dry syrup formulation, which was designed to optimize PK properties of ART-001 and to be compliant with the pediatric population.

Open surgical treatment for aortic arch and coronary artery aneurysms associated with immunoglobulin G4-related disease: a case report.

Background: Immunoglobulin G4-related disease (IgG4RD) is a systemic autoimmune disease characterized by a dense lymphoplasmacytic infiltrate containing IgG4-positive plasma cells that can cause aneurysms in various organs and tissues. There have been many reports of IgG4RD aneurysms; however, the surgical procedures adopted remain controversial. Herein, we report a case in which surgical treatment for IgG4-related aneurysms was successful.

Extensive chronic perianal pyoderma associated with persistent inflammation caused by wearing the same unwashed underwear for more than ten years.

Key Clinical Message: Poor personal hygiene wearing the same unwashed briefs, and prolonged sitting have led to the development of chronic perianal pyoderma. This can be confused with hidradenitis suppurativa and must be differentiated as their treatments are different.

Abstract: There are potential risks of persistent inflammation resulting from poor personal hygiene.

Examination of age-related changes in the submandibular glands of male mice.

Salivary gland hypofunction adversely affects the oral environment and daily life by causing dry mouth (xerostomia). Senescence-related atrophy of salivary gland tissues is one cause of xerostomia, and it is particularly common among the elderly. However, the underlying mechanism is poorly understood, and no treatment has been established.

Postprandial fatty acid metabolism with coconut oil in young females: a randomized, single-blind, crossover trial.

Background: Approximately 84% of the fatty acids contained in coconut oil (CO) are saturated fatty acids (SFAs), and approximately 47% of the SFA are lauric acid with 12 carbon atoms. Lauric acid carbon chain length is intermediate between medium and long-chain fatty acids (LCFAs). We examined how CO acts on lipid-related substances in the blood to determine whether its properties were similar to medium-chain fatty acids (MCFAs) or LCFAs.
