OBJECTIVES: The tumor suppressor gene SMAD4 (DPC4) is genetically inactivated in approximately half of pancreatic ductal adenocarcinomas (PDAs). We examined whether Smad4 tumor status was associated with outcomes after adjuvant chemoradiation (CRT) for resected PDAs. METHODS: Patients treated with adjuvant CRT were identified (N = 145). Smad4 status was determined by immunolabeling and graded as intact or lost. Kaplan-Meier method and multivariable competing risk analyses were performed...

BACKGROUND: Atraumatic lower limb amputation is a life-changing event for approximately 185,000 persons in the United States each year. A unilateral amputation is associated with rapid changes to the musculoskeletal system including leg and back muscle atrophy, strength loss, gait asymmetries, differential mechanical joint loading and leg length discrepancies. Even with high-quality medical care and prostheses, amputees still develop secondary musculoskeletal conditions such as chronic low back pain (LBP)...

This article concentrates on methadone maintenance as a normalizer for the impairments of opioid addiction, and the misunderstandings of it as a substitute for heroin that continues an opiate addiction. Methadone treatment was developed by Drs. Dole, Nyswander, and Kreek. Their cutting-edge theory transformed the way that opioid addiction is perceived and their work changed methadone from a narcotic to withdraw addicts to a medication that is a maintenance normalizer for a chronic condition. Their extensive research involved the physiological and sociological normalizing effects of methadone and medical safety of the medication (Dole & Nyswander, 1967)...

Under the leadership of Drs. Vincent P. Dole, Marie Nyswander, and Mary Jeanne Kreek, in collaboration with the psychologist, Norman Gordon and sociologist, Herman Joseph at The Rockefeller University beginning in the 1960s, the first medical treatment for heroin addiction was developed. Drs. Dole, Nyswander and Kreek also developed the first hypothesis of opiate addiction as a metabolic disease. This biological revolution challenged beliefs about addiction, spurred further research and challenged legal positions of the judiciary and the broader criminal justice system (Dole & Nyswander, 1967 )...

Several countries are experiencing public health crises as a result of opioid addiction. Fatal overdoses have reached record highs in many regions and Hepatitis C virus is the norm among people who inject drugs in several countries. Thus, providing for the global availability of medication-assisted treatment (MAT) for opioid addiction is more important than ever. In this article, we introduce readers to the collection of papers that appear in this special issue on MAT for opioid addiction. We describe the articles and commentaries thematically to include topics that address 1) the contemporary history of methadone maintenance, 2) the provision of and access and barriers to MAT, 3) compliance and outcomes of MAT, 4) health issues among MAT patients, 5) race, ethnicity, and social class backgrounds of MAT patients, 6) criminalization and stigma, and 7) challenges associated with the expansion of MAT...

PURPOSE: To investigate whether the vessels surrounding a nodule depicted on non-contrast, low-dose computed tomography (LDCT) can discriminate benign and malignant screen detected nodules. MATERIALS AND METHODS: We collected a dataset consisting of LDCT scans acquired on 100 subjects from the Pittsburgh Lung Screening study (PLuSS). Fifty subjects were diagnosed with lung cancer and 50 subjects had suspicious nodules later proven benign. For the lung cancer cases, the location of the malignant nodule in the LDCT scans was known; while for the benign cases, the largest nodule in the LDCT scan was used in the analysis...

Heterogeneous metal oxide catalysts are widely studied for the aerobic oxidations of C1-C4 alkanes to form olefins and oxygenates. In this review, we outline the properties of supported metal oxides, mixed-metal oxides, and zeolites and detail their most common applications as catalysts for partial oxidations of light alkanes. By doing this we establish similarities between different classes of metal oxides and identify common themes in reaction mechanisms and research strategies for catalyst improvement. For example, almost all partial alkane oxidations, regardless of the metal oxide, follow Mars-van Krevelen reaction kinetics, which utilize lattice oxygen atoms to reoxidize the reduced metal centers while the gaseous O2 reactant replenishes these lattice oxygen vacancies...

Advances in technology have enabled the delivery of high doses of radiation therapy for pancreatic ductal adenocarcinoma (PDAC) with low rates of toxicity. Although the role of radiation for pancreatic cancer continues to evolve, encouraging results with newer techniques indicate that radiation may benefit selected patient populations. Imaging has been central to the modern successes of radiation therapy for PDAC. Here, we review the role of diagnostic imaging, imaging-based planning, and image guidance in radiation oncology practice for PDAC...

Genome biology approaches have made enormous contributions to our understanding of biological rhythms, particularly in identifying outputs of the clock, including RNAs, proteins, and metabolites, whose abundance oscillates throughout the day. These methods hold significant promise for future discovery, particularly when combined with computational modeling. However, genome-scale experiments are costly and laborious, yielding "big data" that are conceptually and statistically difficult to analyze. There is no obvious consensus regarding design or analysis...

BACKGROUND: The amygdala is a central component of the neural circuitry that underlies fear learning. N-methyl-D-aspartate receptor-dependent plasticity in the amygdala is required for pavlovian fear conditioning and extinction. N-methyl-D-aspartate receptor activation requires the binding of a coagonist, D-serine, which is synthesized from L-serine by the neuronal enzyme serine racemase (SR). However, little is known about SR and D-serine function in the amygdala. METHODS: We used immunohistochemical methods to characterize the cellular localization of SR and D-serine in the mouse and human amygdala...
