Laryngeal cancer occurs more frequently in head and neck cancers, so there are a number of reports regarding the treatment results,wherein the therapeutic strategy and results are stable to some extent. However, due to the spread of chemoradiotherapy, there are differences in the larynx preservation rates for T2 and T3 cases, depending on the facility. Our department has been administering chemoradiotherapy for advanced cancer based on the perspective of conserving the organ and the function. We herein report our examination of 20 laryngeal cancer cases receiving concomitant therapy with S-1, Nedaplatin, and radiation (hereinafter, referred to as SN therapy) in our department from April 2005 to December 2008. The resulting complete response (CR) rate for the SN therapy was 82.4%, excluding T4 cases. Due to their refusal of surgery, 2 of 3 cases in which the SN therapy had been administered for T4 cases receiving SN therapy showed CR, wherein the CR rate in all cases after the SN therapy was 80. 0%. The larynx preservation rate after the SN therapy was 94.1%.

Drug repurposing is a promising strategy for managing cardiovascular disease (CVD) in geriatric populations, offering efficient and cost-effective solutions. CVDs are prevalent across all age groups, with a significant increase in prevalence among geriatric populations. The middle-age period (40-65 years) is critical due to factors like obesity, sedentary lifestyle, and psychosocial stress.

Claudins (CLDNs) play a crucial and indispensable role as fundamental components within the structure of tight junctions. Due to the distinct and unique distribution pattern exhibited by CLDNs in both normal and malignant tissues, these proteins have garnered significant attention as pivotal targets for systemic anti-cancer therapy and as noteworthy diagnostic markers. This review provides a comprehensive and detailed elucidation of the fundamental understanding surrounding CLDNs, their intricate expression patterns, the potential role they play in cancer diagnosis and therapeutic potentials; all encapsulated within a succinct summary of the cutting-edge advancements and the information derived from various clinical trials.

Introduction: Herpes encephalitis is known to affect patients undergoing brain radiotherapy, but early diagnosis and treatment, the foremost determinants of disease outcome, remain challenging in this patient population. This can be due to attribution of symptoms to the brain tumor and radiation side effects, as well as patients' atypical clinical presentation. Here we sought to highlight pearls and pitfalls in the clinical course and diagnostic workup which may facilitate timely diagnosis and improve disease outcome.

Significant progress has been made in cancer therapy with protein-based nanocarriers targeted directly to surface receptors for drug delivery. The nanocarriers are a potentially effective solution for the potential drawbacks of traditional chemotherapy, such as lack of specificity, side effects, and development resistance. Peptides as nanocarriers have been designed based on their biocompatible, biodegradable, and versatile functions to deliver therapeutic agents into cancer cells, reduce systemic toxicity, and maximize therapy efficacy through utilizing targeted ligands such as antibodies, amino acids, vitamins, and other small molecules onto protein-based nanocarriers and thus ensuring that drugs selectively accumulate in the cancer cells instead of healthy organs/drug release at a target site without effects on normal cells, which inherently caused less systemic toxicity/off-target effect.

Background: Patients with Crohn's disease face an elevated risk of colorectal cancer, in part due to underlying chronic inflammation. Biologic therapy is the mainstay of medical treatment; however, the impact of treatment on colorectal cancer-related outcomes remains unclear.
Objective: To investigate the association between prior exposure to biologic treatment and colorectal cancer-related outcomes in patients with underlying Crohn's disease.
