A 77-year-old Caucasian male was diagnosed with squamous cell cancer of the right ear. The patient elected to take part in the first-in-man phase I TPCS based bleomycin photochemical internalization (PCI). On Day 0, The patient received the photosensitiser [Amphinex (TPCS)], by slow intravenous injection. Four days later, surface illumination based (PCI) was implemented 3 h after the slow infusion of Bleomycin. Four weeks following the infusion of the photosensitiser, the cancerous area turned into black rigid mass with clear demarcation from the macroscopically normal skin. The size of the treated area has been substantially reduced. Histopathologic assessment of the excised necrotic mass revealed no viable tumour and the excised margins (PCI-treated margins) were tumour-free. This case was a clear indication that PCI is a clinically relevant technique that has potential in the treatment of such cancers to avoid radical intervention.

Early childhood caries (ECC), a severe form of dental caries, is exacerbated by the synergistic interaction between Streptococcus mutans and Candida albicans, leading to greater disease severity than their individual effects. This underscores the need for more targeted and potent therapeutic alternatives. Given the promising anti-infective properties of quaternary ammonium surfactants (QAS), this study explores the microbicidal properties of one such QAS, cetyltrimethylammonium chloride (CTAC), against both individual- and dual-species cultures of S.

Introduction: ICAM-1 is an adhesion molecule expressed on the endothelial cells and is involved in regulating leukocyte recruitment to the site of inflammation. Elevated ICAM-1 mRNA expression was found in the serum of mothers with chorioamnionitis. This study aimed to determine the expression of ICAM-1 in the placenta and umbilical cord of pregnancy with chorioamnionitis, and its association with adverse neonatal outcome.

Mental disorders are complex illnesses with multifactorial etiologies involving genetic and environmental components. This review focuses on cellular models derived from the olfactory epithelium as a promising tool to study the molecular mechanisms of some neuropsychiatric diseases. The authors consider cell lines allowing the identification of potential biomarkers and pathogenetic mechanisms of schizophrenia, bipolar disorder, and Alzheimer's disease.

We explored whether analysis using total cfDNA is efficacious for Japanese patients with oral squamous cell carcinoma (OSCC).
Methods: We collected total cfDNA from nine patients with OSCC preoperatively, 1 month postoperatively, and every 3 months thereafter to analyze this association.

Background: Increased reactive oxygen species (ROS) are involved in the pathological process of dry eye disease. Our previous results suggested that norepinephrine (NE) has a protective effect on dry eye.
Purpose: This study explored the potential therapeutic role and underlying mechanisms of NE in benzalkonium chloride (BAC)-induced dry eye disease.
