Generation of Replication-Competent Hepatitis B Virus Harboring Tagged Polymerase for Visualization and Quantification of the Infection.

Hepatitis B virus (HBV) infection is a serious global health problem causing acute and chronic hepatitis and related diseases. Approximately, 296 million patients have been chronically infected with the virus, leading to cirrhosis and hepatocellular carcinoma. Although HBV polymerase (HBVpol, pol) plays a pivotal role in HBV replication and must be a definite therapeutic target.

Development of Worksheets for Immunomodulator Shared Decision-Making to Facilitate Patient-Clinician Communication: A Quality Improvement Project Employing Design Thinking Principles.

Background: Shared decision-making (SDM) is a principle of humanistic, patient-centered health care within the field of rheumatology. However, clear communication between patients and their clinicians regarding the benefits and risks of immunomodulators may be challenging in a clinical setting. The design-thinking process is a human-centered approach to quality improvement that can help to identify insights to uphold high-quality communication.

Analysis of the Effector Functions of Vδ2 γδ T Cells and NK Cells against Cholangiocarcinoma Cells.

Cholangiocarcinoma (CCA) is a rare disease characterized by malignant cells derived from the epithelial cells of the biliary duct system. Despite extensive treatments, the prognosis for CCA remains poor, emphasizing the critical need for the development of novel treatments. Considerable attention has been directed towards innate immune effector cells, which can recognize tumor cells independently of the major histocompatibility complex, laying the foundation for the development of off-the-shelf drugs.

Efficacy of first-line immune checkpoint inhibitor and anti-angiogenic agent combination therapy for Kirsten rat sarcoma viral antigen-mutant advanced non-small-cell lung cancer: a systematic review and network meta-analysis.

Background: Recent advancements in advanced non-small-cell lung cancer (NSCLC) treatment have significantly improved primary therapy outcomes owing to the emergence of various molecular targeted therapies and immune checkpoint inhibitors (ICIs). However, for Kirsten rat sarcoma viral antigen (KRAS) mutations, molecular targeted drugs, such as sotorasib, are not applicable as first-line treatments, and the optimal primary treatment remains unclear. Therefore, we aimed to investigate the efficacy of ICI combination therapy as first-line treatment for KRAS-mutant NSCLC.

Background: Resistance training adaptively increases muscle strength and mass, contributing to athletic performance and health promotion. Dietary intervention with natural foods provides nutrients that help accelerate muscle adaptation to training. Matcha green tea contains several bioactive factors such as antioxidants, amino acids, and dietary fibers; however, its effect on muscle adaptation is unclear.

Effects of integrated hospital treatment on the default mode, salience, and frontal-parietal networks in anorexia nervosa: A longitudinal resting-state functional magnetic resonance imaging study.

The psychopathology of patients with anorexia nervosa has been hypothesized to involve inappropriate self-referential processing, disturbed interoceptive awareness, and excessive cognitive control, including distorted self-concern, disregard of their own starvation state, and extreme weight-control behavior. We hypothesized that the resting-state brain networks, including the default mode, salience and frontal-parietal networks, might be altered in such patients, and that treatment might normalize neural functional connectivity, with improvement of inappropriate self-cognition. We measured resting-state functional magnetic resonance images from 18 patients with anorexia nervosa and 18 healthy subjects before and after integrated hospital treatment (nourishment and psychological therapy).

Difficult removal after bronchial filling of an endobronchial Watanabe spigot with N-butyl-2-cyanoacrylate for intractable pneumothorax: A case report.

A 52-year-old man developed a right pneumothorax during treatment for COVID-19. In a previous case report concerning this patient, his recovery was achieved through implanting four endobronchial Watanabe spigots (EWS) in the right B1 and B3 in two phases and spraying N-butyl-2-cyanoacrylate (NBCA). One year later, EWS removal was planned.

A case of a thoracic mass negative on thoracentesis diagnosed by cryobiopsy from the visceral pleura.

Thoracoscopy under local anaesthesia is recommended for malignant tumours with negative pleural effusion cytology. Cryobiopsy from the visceral pleura by thoracoscopy under local anaesthesia can provide more diagnostic options for patients with thoracentesis-negative malignant effusions. Here we present the first case in which this technique was used.

Investigation of radical scavenging effects of acetaminophen, p-aminophenol and their O-sulfated conjugates.

Acetaminophen (APAP) and p-aminophenol (p-AP) are the analogous simple phenolic compounds that undergo sulfate conjugation (sulfation) by cytosolic sulfotransferases. Sulfation is generally thought to lead to the inactivation and disposal of endogenous as well as xenobiotic compounds. This study aimed to investigate the antioxidative effects of O-sulfated form of APAP and p-AP, i.

We herein report a case of hemorrhagic shock due to intercostal artery injury that occurred during initial trauma care (ITC) treated by resuscitative thoracotomy (RT) and transcatheter arterial embolization (TAE) with multiple displaced rib fractures (RFs) and traumatic head injury (THI). A man in his 50s who was injured in a traffic accident was transferred to our institution by helicopter for emergency medical treatment.

Combined treatment with endobronchial Watanabe spigot and -butyl-2-cyanoacrylate for refractory pneumothorax in COVID-19.

Coronavirus disease 2019 (COVID-19) causes pneumothorax or mediastinal emphysema in approximately 1% of patients. According to the British Thoracic Society guidelines, the next treatment option for patients with persistent pneumothorax despite chest drainage is pleurodesis or surgery. In fact, there are reports of autologous blood pleurodesis or surgery for the treatment of pneumothorax caused by COVID-19.

Development of dentition: From initiation to occlusion and related diseases.

Background: The development of dentition begins in the embryonic oral cavity and progresses in the branchial arches and alveolar bone. Continuous cellular and molecular crosstalk occurs during crown formation, after which the tooth germ begins to migrate apically through the alveolar process into the oral cavity. It eventually comes in contact with its antagonist in the contralateral jaw to establish functional occlusion.

Sequential HBV treatment with tenofovir alafenamide for patients with chronic hepatitis B: week 96 results from a real-world, multicenter cohort study.

Background: Coronavirus disease 2019 (COVID-19), which is caused by severe acute respiratory syndrome coronavirus 2, has been a significant concern worldwide since its outbreak in December 2019. Various treatments are being researched and developed, and there are reports that dexamethasone has reduced the mortality rate and improved the clinical course of critically ill patients with COVID-19. In this study, we examined the clinical efficacy of corticosteroid therapy for patients with COVID-19 in our hospital during the first wave of infections.

PD-1 checkpoint blockade enhances adoptive immunotherapy by human Vγ2Vδ2 T cells against human prostate cancer.

Human Vγ2Vδ2 (also termed Vγ9Vδ2) T cells play important roles in microbial and tumor immunity by monitoring foreign- and self-prenyl pyrophosphate metabolites in isoprenoid biosynthesis. Accumulation of isoprenoid metabolites after bisphosphonate treatment allows Vγ2Vδ2 T cells to recognize and kill tumors independently of their MHC expression or burden of non-synonymous mutations. Clinical trials with more than 400 patients show that adoptive immunotherapy with Vγ2Vδ2 T cells has few side effects but has resulted in only a few partial and complete remissions.
