Colorectal cancer (CRC) is a common human malignancy worldwide and increasing studies have attributed its malignant progression to abnormal molecular changes in cancer cells. Nuclear division cycle 80 (NDC80) is a newly discovered oncoprotein that regulates cell proliferation and cycle in numerous malignancies. However, its clinical significance and biological role in CRC remain unclear. Therefore, in this study, we firstly analyze its expression in a retrospective cohort enrolling 224 CRC patients and find its overexpression is significantly correlated with advanced tumor stage and poor prognosis in CRC patients...

Objectives: In recent years, the application of radiopharmaceuticals in nuclear medicine has increased substantially. Following the diagnostic procedures performed in nuclear medicine departments, such as myocardial perfusion imaging, patients generally receive considerable doses of radiation. Normally, radiation-induced DNA damages are expected following exposure to a low-dose ionizing radiation. In order to detect molecular changes, high-sensitivity techniques must be utilized. The aim of this study was to assess the effect of a low-dose (below 10 mSv) gamma ray on gene expression using quantitative real-time polymerase chain reaction (qRT-PCR)...

Cystoisospora is responsible for morbidity in immunocompromised patients. PCR is sensitive for diagnosing Cystoisospora; however, it needs reevaluation for differential molecular diagnosis of cystoisosporiasis. We aimed at evaluating melting curve analysis (MCA) after real-time PCR (qPCR) in diagnosis and genotyping of Cystoisospora as an alternative to conventional PCR. We included 293 diarrheic stool samples of patients attending the Department of Clinical Oncology and Nuclear Medicine of Cairo University Hospitals, Egypt...

In the high volume general practitioner setting, there is a need for triaging clinical questions pertaining to specific patients into ones that are readily answered, and those that would more effectively and efficiently be answered by the subspecialist. In this way, the nuclear medicine consultation provides the general practitioner a physiologic imaging specialist's perspective for answering complex clinical questions. A formal nuclear medicine consultation can be a valuable tool in identifying a targeted molecular imaging approach to answering a specific clinical question and can prove useful in both appropriate diagnostic study selection as well as accurate image interpretation...

Molecular checkpoints that trigger the onset of islet autoimmunity or progression to human type 1 diabetes (T1D) are incompletely understood. Using T cells from children at an early stage of islet autoimmunity without clinical T1D, we find that a microRNA181a (miRNA181a)-mediated increase in signal strength of stimulation and costimulation links nuclear factor of activated T cells 5 (NFAT5) with impaired tolerance induction and autoimmune activation. We show that enhancing miRNA181a activity increases NFAT5 expression while inhibiting FOXP3+ regulatory T cell (Treg) induction in vitro...

Conformational diseases represent a new aspect of proteomic medicine where diagnostic and therapeutic paradigms are evolving. In this context, the early biomarkers for target cell failure (neurons, β-cells, etc.) represent a challenge to translational medicine and play a multidimensional role as biomarkers and potential therapeutic targets. This systematic review, which follows the PICO and Prisma methods, analyses this new-fangled multidimensionality, its strengths and limitations, and presents the future possibilities it opens up...

Many natural products from medicinal plants are small molecular weight compounds with enormous structural diversity and show various biological activities. Magnolol is a biphenol compound rich in the stem bark of Magnolia officinalis Rehd et Wils., and is able to suppress viral replication in GCRV-infected grass carp (Ctenopharyngodon idella) kidney (CIK) cells in the previous study. In this study, in vivo studies demonstrated that magnolol was efficient to restrain the replication of GCRV and repair the low level of superoxide dismutase and total antioxidant capacity in serum at the non-toxic concentration in vivo...

Molecular imaging technologists are faced with statistics on a daily basis because they image patients who have been selected for diagnostic testing based on analysis of how well the test performs, and because technical factors can influence the performance of any diagnostic test. Choosing what test procedure to perform on which patient is a matter of understanding the patient's pretest likelihood of disease, the performance characteristics of the diagnostic test, and other clinical factors which may impact the usefulness of the results...

Ultraviolet A (UVA) irradiation is toxic to skin as it penetrates deep into the dermis and damages cellular components through excessive reactive oxygen species (ROS) production, which accelerates photoaging and skin cancer. We evaluated the dermato-protective efficacies of zerumbone (natural sesquiterpene of Zingiber zerumbet) in UVA-irradiated human skin keratinocyte (HaCaT) cells and mouse epidermis. Zerumbone pretreatment (2-10 μM) substantially suppressed UVA (15 J/cm2)-induced HaCaT cell death and lactate dehydrogenase release in a dose-dependent manner...

Cardiac transthyretin-related (ATTR) amyloidosis is a severe cardiomyopathy for which therapeutic approaches are currently under development. Because non-invasive imaging techniques such as cardiac magnetic resonance imaging and echocardiography are non-specific, the diagnosis of ATTR amyloidosis is still based on myocardial biopsy. Thus, diagnosis of ATTR amyloidosis is difficult in patients refusing myocardial biopsy. Furthermore, myocardial biopsy does not allow 3D-mapping and quantification of myocardial ATTR amyloid...

Acute myeloid leukemia (AML) is a heterogeneous disease characterized by the accumulation of immature myeloid progenitor cells in the bone marrow, compromising of normal blood cell production and ultimately resulting in bone marrow failure. With a 20% overall survival rate at 5 years and 50% in the 18- to 65-year-old age group, new medicines are needed. It is proposed that development of repurposed drugs may be a part of the new therapy needed. AML is subdivided into recurrent molecular entities based on molecular genetics increasingly accessible for precision medicine...

Background: While recent genome wide association studies have suggested novel low-grade glioma (LGG) stratification models based on a molecular classification, we explored the potential clinical utility of patient-derived cells. Specifically, we assayed glioma-associated stem cells (GASC) that are patient-derived stem cells representative of the glioma microenvironment. Methods: By next generation sequencing, we analyzed the transcriptional profile of GASC derived from patients that underwent anaplastic transformation either within 48 months (GASC-BAD) or ≥7 years (GASC-GOOD) after surgery...

Owing to their success in clinical practice, the prevalence of cardiovascular implants is continuously increasing. Implant infection is a relevant complication but remains a diagnostic challenge because echocardiography as a first-line test may be limited. Accordingly, a multimodality approach is increasingly used for diagnostic workup and supported by recent guidelines. As reviewed here, computed tomography and nuclear imaging provide incremental diagnostic value and may be combined in a single hybrid imaging session using positron emission tomography/computed tomography or single photon emission computed tomography/computed tomography...
