Background: Diabetes has been proposed to be a risk factor for and a consequence of pancreatic cancer (PC). The relationship between recent-onset diabetes and PC is not well understood, and data in minorities are sparse. We examined the relationships between recent-onset diabetes and PC incidence in African Americans and Latinos in the Multiethnic Cohort. Methods: A total of 48 995 African Americans and Latinos without prior diabetes and cancer at baseline (1993-1996) were included in the study...

MiR-30d-5p, a member of the microRNA family, was recently reported to regulate androgen receptor signaling in prostate cancer (PCa). Ecto-5'-nucleotidase (NT5E/CD73) is a pivotal regulator of tumor migration and has angiogenetic properties. However, the undiscovered function of miR-30d-5p and whether it targeted NT5E in PCa remain uncertain. In this study, the authors observed miR-30d-5p was significantly downregulated in PCa tissues and cell lines compared with the adjacent normal tissues and normal prostate cells, respectively...

Owing to the lack of databases of blood flow distributions in the external carotid branches, surgeons currently rely on per-operative imaging and on their experience to choose the recipient vessels for microsurgical facial reconstructions. But, thanks to three-dimensional phase contrast angiography (PCA) and kinematic CINE phase contrast (PC) sequences, MRI technologies have the potential to provide quantitative anatomical and hemodynamic information without injection of contrast agent. Having developed and optimized PC-MRI sequences for the small facial vessels, our objective was to investigate the haemodynamic and blood flow distribution in the external carotid branches...

OBJECTIVES: L'applicazione del metodo della Probability of Causation (PC) è certamente ampio poiché è oggi lo strumento riconosciuto per la individuazione del nesso di causa non solo nelle richieste di indennizzo in ambito assicurativo (per il quale è stata utilizzato inizialmente) ma anche per dirimere contenziosi giuridici in ambito civilistico e penalistico. METHODS: Thanks to the Italian Association of Medical Radiation Protection (AIRM), PC method has been recently proposed as an aid for the radiation protection occupational physician in medical assessments involving both the mandatory actions that, in case of suspicion of occupational disease, the physician needs to perform (report / complaint / reporting) and the expression of the fitness evaluation in case of return to work after cancer and clinical recovery...

OBJECTIVES: The Probability of Causation (PC) was introduced to compensate objectively and more possible legally the U.S. diseased subjects involved in the nuclear armament activities. METHODS: The methodology is related to the attributable risk concept, but it is widely different from it, since it doesn't evaluate the "attributablity" from a collective point of view, but from a "personalistic" point, that is from the particular exposure condition, from the specific physical parameters and from the biological individual features of the single exposed subject...

OBJECTIVES: The continuous scientific advances against neoplastic diseases affecting all areas of oncology biomedical research. Age is an extremely important factor in cancer development, since the incidence of cancer increases significantly with age. Because of aging of the Italian population, although the incidence is kept constant, the number of cancer diagnosis is inevitably going to increase over time only to increasing age. METHODS: Survival after the diagnosis of cancer is one of the main indicators that allow to evaluate the effectiveness of the health system against the cancer disease...

Prostate cancer and osteosarcoma are the second most common type of cancer affecting men and the fifth most common malignancy among adolescents, respectively. The use of non-toxic natural or natural-derived products has been one of the current strategies for cancer therapy, owing to the reduced risks of induced-chemoresistance development and the absence of secondary effects. In this perspective, lactoferrin (Lf), a natural protein derived from milk, emerges as a promising anticancer agent due to its well-recognized cytotoxicity and anti-metastatic activity...

BACKGROUND: Pancreatic ductal adenocarcinoma (PDAC) early diagnosis is  crucial  and new, cheap and user-friendly techniques for biomarker identification  are  needed. "Protein corona" (PC) is emerging a new bio-interface potentially useful in tumor early diagnosis. In a previous investigation, we showed that relevant differences between the  protein patterns of  PCs formed on lipid NPs after exposure to PDAC and non-cancer plasma  samples exist. To extend that research, We performed this pilot study to investigate the effect of PDAC tumor size and distant metastases on PC composition...

Effective disease management of wildlife relies on the strategic application of ante-mortem diagnostic tests for early identification and removal of M. bovis-infected animals. To improve diagnostic performance, interferon-gamma release assays (IGRAs) are often used in conjunction with the tuberculin skin test (TST). Since buffaloes are major maintenance hosts of M. bovis, optimal application of bovine TB diagnostic tests are especially important. We aimed to determine whether the timing of blood collection relative to the TST has an influence on IFN-γ production and diagnostic outcome in African buffaloes...

BACKGROUND: The response to temozolomide (TMZ) treatment in small-cell lung cancer (SCLC) correlated with O(6)-methylguanine -DNA methyltransferase (MGMT) promoter methylation. 1p/19q co-deletion within oligodendroglioma is a responsive predictor for TMZ. Currently, the status of MGMT promoter methylation and 1p/19q co-deletion in pulmonary carcinoid (PC) and large-cell neuroendocrine carcinoma (LCNEC) is not reported. METHODS: Nine PC [two atypical carcinoids (AC), seven typical carcinoids (TC)] and six LCNEC patients were collected retrospectively...

In the lyophilization process for injections, the shelf temperature (Ts ) and chamber pressure (Pc ) have mainly been investigated to optimize the primary drying process. The objective of this study was to show that lyophilization of protein formulations can be achieved by adopting a fast ramp rate of Ts in the beginning of the primary drying process. Bovine serum albumin was used as the model protein, and seven different lyophilized formulations obtained were stored at elevated temperature. We found that although acceptable cake appearance was confirmed by the fast ramp cycle, all formulations of lyophilized cakes obtained by the slow ramp cycle severely collapsed (macrocollapse)...

The differential expression of microRNAs (miRNAs) in plasma of pancreatic cancer (PC) patients may act as a diagnostic biomarker. A four-stage study was performed to identify plasma miRNAs with potential in detecting PC. Exiqon panels (20 PC vs. 10 normal controls (NCs)) were applied in the screening phase to obtain miRNA profiling. The identified miRNAs were further assessed in the training (40 PC vs. 40 NCs) and testing stages (112 PC vs. 116 NCs) with qRT-PCR assays. A six-miRNA signature including up-regulated miR-122-5p, miR-125b-5p, miR-192-5p, miR-193b-3p, miR-221-3p and miR-27b-3p was identified...

There is currently limited knowledge regarding the involvement of long non-coding RNAs (lncRNAs) in cancer development. We aimed to identify lncRNAs with important roles in pancreatic cancer progression. We screened for lncRNAs that were differentially expressed in pancreatic cancer tissues. Among 349 differentially expressed lncRNAs, Linc01060 showed the lowest expression in pancreatic cancer tissues compared with normal pancreatic tissues. Lower Linc01060 expression in pancreatic cancer tissues was significantly associated with a poor prognosis...

A systematic method in hydrophilic interaction chromatography (HILIC) was developed for the separation of four monophosphate nucleotides using design of experiment (DOE) approaches. Three HPLC parameters, the buffer concentration (ammonium acetate concentration), gradient time, and temperature, were evaluated within the quality design framework, and the effects on chromatographic parameters were investigated. Four zwitterionic columns (ZIC-HILIC, ZIC-cHILIC, NUCLEODUR HILIC, and PC HILIC) were used to separate four nucleotides, and the HPLC conditions for each column were successfully optimized, although PC HILIC did not give peaks that were suitable for optimization...

Almost 2.8 million men in the U.S. are living with prostate cancer (PC), accounting for 40% of all male cancer survivors. Men diagnosed with prostate cancer may experience chronic and debilitating treatment side effects, including sexual and urinary dysfunction, pain and fatigue. Side effects can be stressful and can also lead to poor psychosocial functioning. Prior trials reveal that group-based cognitive behavioral stress and self-management (CBSM) is effective in reducing stress and mitigating some of these symptoms, yet little is known about the effects of culturally-translated CBSM among Spanish-speaking men with PC...
