Investigation of Process Induced Defects Using a LTO Process

The effects of process induced defects, such as dislocations and/or oxide induced stacking faults, were investigated for a bipolar process employing solid diffusion sources. Carborundum BN975 Boron Sources have a low temperature oxide (LTD) step to minimize defects. Two bipolar processes, one with and one without LTD were run and electrical tests done to evaluate device characteristics. ~t this point results were inconclusive

Patient Perceptions of Clinician\u27s Empathy: Measurement and Psychometrics.

The prominence of reciprocal understanding in patient–doctor empathic engagement implies that patient perception of clinician’s empathy has an important role in the assessment of the patient–clinician relationship. In response to a need for an assessment tool to measure patient’s views of clinician empathy, we developed a brief (5-item) instrument, the Jefferson Scale of Patient Perceptions of Physician Empathy (JSPPPE). This review article reports evidence in support of the validity and reliability of the JSPPPE

Three-Dimensional Reconstructions of Tadpole Chondrocrania from Historical Sections

Reconstructing three dimensional structures (3DR) from histological sections has always been difficult but is becoming more accessible with the assistance of digital imaging. We sought to assemble a low cost system using readily available hardware and software to generate 3DR for a study of tadpole chondrocrania. We found that a combination of RGB can1era, stereomicro­scope, and Apple Macintosh PowerPC computers running NIH Image, Object Image, Rotater, and SURFdriver software provided acceptable reconstruc­tions. These are limited in quality primarily by the distortions arising from histological protocols rather than hardware or software

Influence of Primary Care Physician Availability and Socioeconomic Deprivation on Breast Cancer from 1988 to 2008: A Spatio-Temporal Analysis

Breast cancer is the most commonly diagnosed cancer and the second leading cause of cancer death among women in the United States. It is unclear how county-level primary care physician (PCP) availability and socioeconomic deprivation affect the spatial and temporal variation of breast cancer incidence and mortality.We used the 1988-2008 public-use county-based data from nine Surveillance, Epidemiology, and End Results (SEER) programs to analyze the temporal and spatial disparity of PCP availability and socioeconomic deprivation on early-stage incidence, advanced-stage incidence and breast cancer mortality. The spatio-temporal analysis was implemented by a novel structural additive modeling approach.Greater PCP availability was significantly associated with higher early-stage incidence, advanced-stage incidence and mortality during the entire study period while socioeconomic deprivation was significantly negatively associated with early-stage incidence, advanced-stage incidence, and mortality up to 1992. However, the observed influence of PCP availability and socioeconomic deprivation varied by county.We showed important associations of PCP availability and socioeconomic deprivation with the three breast cancer indicators. However, the effect of these associations varied over time and across counties. The association of PCP availability and socioeconomic deprivation was stronger in selected counties

The effect of Humanitude care methodology on improving empathy: a six-year longitudinal study of medical students in Japan.

BACKGROUND: Empathy, which involves understanding another person\u27s experiences and concerns, is an important component for developing physicians\u27 overall competence. This longitudinal study was designed to test the hypothesis that medical students\u27 empathy can be enhanced and sustained by Humanitude Care Methodology, which focuses on perception, emotion and speech. METHODS: This six-year longitudinal observational study examined 115 students who entered Okayama University Medical School in 2013. The study participants were exposed to two empathy-enhancing programs: (1) a communication skills training program (involving medical interviews) and (2) a Humanitude training program aimed at enhancing their empathy. They completed the Jefferson Scale of Empathy (JSE) seven times: when they entered medical school, before participation in the first program (medical interview), immediately after the first program, before the second program (Humanitude exercise), immediately after the second program, and in the 5th and 6th year (last year) of medical school. A total of 79 students (69% of the cohort) completed all seven test administrations of the JSE. RESULTS: The mean JSE scores improved significantly after participation in the medical interview program (p \u3c 0.01) and the Humanitude training program (p = 0.001). However, neither program showed a sustained effect. CONCLUSIONS: The Humanitude training program as well as medical interview training program, had significant short-term positive effects for improving empathy among medical students. Additional reinforcements may be necessary for a long-term sustained effect

T Cell Cancer Therapy Requires CD40-CD40L Activation of Tumor Necrosis Factor and Inducible Nitric-Oxide-Synthase-Producing Dendritic Cells

Effective cancer immunotherapy requires overcoming immunosuppressive tumor microenvironments. We\ua0found that local nitric oxide (NO) production by tumor-infiltrating myeloid cells is important for adoptively transferred CD8(+) cytotoxic T\ua0cells to destroy tumors. These myeloid cells are phenotypically similar to inducible nitric oxide synthase (NOS2)- and tumor necrosis factor (TNF)-producing dendritic cells (DC), or Tip-DCs. Depletion of immunosuppressive, colony stimulating factor 1 receptor (CSF-1R)-dependent arginase 1(+) myeloid cells enhanced NO-dependent tumor killing. Tumor elimination via NOS2 required the CD40-CD40L pathway. We also uncovered a strong correlation between survival of colorectal cancer patients and NOS2, CD40, and TNF expression in their tumors. Our results identify a network of pro-tumor factors that can be targeted to boost cancer immunotherapies

Executive Summary of the Early-Onset Breast Cancer Evidence Review Conference.

The Centers for Disease Control and Prevention launched the Bring Your Brave campaign to increase knowledge about early-onset breast cancer, defined as breast cancer in women aged 18-45 years. The American College of Obstetricians and Gynecologists convened a panel of experts in breast disease from the Society for Academic Specialists in General Obstetrics and Gynecology to review relevant literature, validated tools, best practices, and practice guidelines as a first step toward developing educational materials for women\u27s health care providers about early-onset breast cancer. Panel members conducted structured literature reviews, which were then reviewed by other panel members and discussed at an in-person meeting of stakeholder professional and patient advocacy organizations in April 2019. This article summarizes the relevant literature, existing guidance, and validated tools to guide health care providers in the prevention, early detection, and special considerations of early-onset breast cancer. Substantive knowledge gaps were noted and summarized to provide guidance for future research
