Development of small, cost-efficient scintillating fiber detectors for automated synthesis of positron emission tomography radiopharmaceuticals.

Background: Radiolabeling is critical in complex chemical reactions involving positron emission tomography (PET) radiotracer production. The process is now automated within a synthesis module to enhance efficiency and reduce radiation exposure. The key to this automation is the use of radiation detectors to monitor radioactivity transfer and ensure the progression of reactions.

Association Between Body Mass Index and Clinical Outcomes of Gender-Affirming Masculinizing Chest Reconstruction.

Introduction: Body mass index (BMI) is often used in surgical settings to determine patients' risk of complications. In the context of gender-affirming care, BMI requirements for surgery can limit access to necessary care for larger-bodied people. There is a critical need to understand the association between BMI and postoperative outcomes for this population.

Therapeutic activity of retroviral replicating vector-mediated gene therapy in combination with anti-PD-1 antibody in a murine pancreatic cancer model.

Toca 511, a tumor-selective retroviral replicating vector encoding the yeast cytosine deaminase (yCD) gene, exerts direct antitumor effects through intratumoral prodrug 5-fluorocytosine (5-FC) conversion to active drug 5-fluorouracil by yCD, and has demonstrated therapeutic efficacy in preclinical and clinical trials of various cancers. Toca 511/5-FC treatment may also induce antitumor immunity. Here, we first examined antitumor immune responses activated by Toca 511/5-FC treatment in an immunocompetent murine pancreatic cancer model.

Long-term benefits to psychological health and well-being after ceremonial use of Ayahuasca in Middle Eastern and North African immigrants and refugees.

Background: Refugees and immigrants can experience complex stressors from the process of immigration that can have lasting and severe long-term mental health consequences. Experiences after ayahuasca ingestion are shown to produce positive effects on psychological wellbeing and mental health, including anecdotal reports of improved symptoms of trauma and related disorders. However, data on the longitudinal health impact of naturalistic ayahuasca use in Middle Eastern and North African (MENA) immigrant and refugee populations is limited.
