REVIEW
Benita L McVicker, Robert G Bennett
Fibrosis is a major player in cardiovascular disease, both as a contributor to the development of disease, as well as a post-injury response that drives progression. Despite the identification of many mechanisms responsible for cardiovascular fibrosis, to date no treatments have emerged that have effectively reduced the excess deposition of extracellular matrix associated with fibrotic conditions. Novel treatments have recently been identified that hold promise as potential therapeutic agents for cardiovascular diseases associated with fibrosis, as well as other fibrotic conditions...

At present, three-dimensional (3D) printing has been applied in many aspects in the field of prosthodontics, such as dental models, wax patterns, guide plates, dental restoration and customized implants. The common forming principles include light curing, sintering and melting-condensation, the materials include pure wax, resin, metal and ceramics. However, the printing precision and the strength of multi-material integrated forming, remains to be improved. In addition, as a technology by which the internal structure of a material can be customized manufacturing, further advantage of 3D printing used in the manufacture of dental restoration lies in the customization functional bionic micro-structures, but the related research is still in its infancy...

Diabetic hepatosclerosis is a novel entity that has recently been introduced by reviewing archived liver biopsies as a non-cirrhotic form of peri-sinusoidal fibrosis with basement membrane formation. Diabetic hepatosclerosis is usually characterized by an indolent clinical course. Serum aminotransferase levels are normal or minimally elevated, but elevated alkaline phosphatase levels is usually present. Clinically relevant to DH is the co-existence of other diabetic microvascular complications in the same patient, such as ESRD on long-term dialysis or renal transplantation, retinopathy, or neuropathy...

Chronic lymphocytic leukemia (CLL) is a B lineage neoplasm, characterized by the accumulation of B lymphocytes of great longevity, and usually develops as a result of the inhibition of apoptosis. Clinical evolution is extremely variable amongst affected individuals with survival ranging from a few months in aggressive cases, to a few decades in cases of indolent CLL. The identification of new prognostic factors, apart from clinical staging, has been an important research topic aiming at a better understanding of CLL...

Despite advances in diagnosis and new treatments such as targeted therapies, breast cancer (BC) is still the most prevalent tumor in women worldwide and the leading cause of death. The principal obstacle for successful BC treatment is the acquired or de novo resistance of the tumors to the systemic therapy (chemotherapy, endocrine, and targeted therapies) that patients receive. In the era of personalized treatment, several studies have focused on the search for biomarkers capable of predicting the response to this therapy; microRNAs (miRNAs) stand out among these markers due to their broad spectrum or potential clinical applications...

BACKGROUND: Biomarkers are indispensable tools for screening, diagnosis, and prognosis in cardiovascular diseases and their clinical application increases steadily. As cardiovascular diseases include various pathophysiological processes, no single biomarker, even natriuretic peptides, can be regarded as ideal fulfilling all necessary criteria for a comprehensive diagnostic or prognostic assessment revealing optimal clinical application. Hence, the multi-marker approaches using different biomarkers reflecting different pathophysiologies were highlighted recently...

Head and neck cancer is one of the leading malignancies worldwide. Due to the lack of symptoms in the early stage of the disease, about two thirds of patients present with locally advanced disease at the time of diagnosis. Even with significantly improved survival rates over the past two decades due to advanced imaging and treatment modalities, locoregional recurrence rates in patients with advanced disease ranges from 16% to 35%. Alternative therapeutic targets are being developed to improve survival outcomes...

Survivin is a protein functionally important for cell division, apoptosis, and possibly, for micro-RNA biogenesis. It is an established marker of malignant cell transformation. In non-malignant conditions, the unique properties of survivin make it indispensable for homeostasis of the immune system. Indeed, it is required for the innate and adaptive immune responses, controlling differentiation and maintenance of CD4(+) and CD8(+) memory T-cells, and in B cell maturation. Recently, survivin has emerged as an important player in the pathogenesis of autoimmune diseases...

BACKGROUND: Discourse is fundamental to everyday communication, and is an increasing focus of clinical assessment, intervention and research. Aphasia can affect the information a speaker communicates in discourse. Little is known about the psychometrics of the tools for measuring information in discourse, which means it is unclear whether these measures are of sufficient quality to be used as clinical outcome measures or diagnostic tools. AIMS: To profile the measures used to describe information in aphasic discourse, and to assess the quality of these measures against standard psychometric criteria...

Frank P DiFilippo
PURPOSE: Tri-PET refers to high-resolution 511-keV emission tomography using a multi-pinhole collimator in conjunction with lower-resolution PET detectors operating in coincidence mode. Tri-PET is unique in that three spatial locations are associated with each event (two detector coordinates and one pinhole location). Spatial resolution and sensitivity are similar to that of 511-keV SPECT and are governed mainly by the collimator design. However because of a third spatial location in Tri-PET, the line of response is overdetermined...

Ultrasound (US) is one of the most frequently used imaging methods in the clinic. The broad spectrum of its applications can be increased by the use of gas-filled microbubbles (MB) as ultrasound contrast agents (UCA). In recent years, also nanoscale UCA like nanobubbles (NB), echogenic liposomes (ELIP) and nanodroplets have been developed, which in contrast to MB, are able to extravasate from the vessels into the tissue. New disease-specific UCA have been designed for the assessment of tissue biomarkers and advanced US to a molecular imaging modality...

Dietary phenolic compounds (PCs) have been receiving interest for their presumed roles in disease prevention. However, there is a lack of studies on the underlying molecular mechanisms. In this regard, in vitro metabolomic approaches are suitable for the investigation of the molecular changes in response to PC exposure. Up to date, the biological effects of PCs have only been examined for PCs from rosemary (Rosmarinus officinalis), olive oil, and resveratrol using cell-based metabolomic approach, although transcriptomic and/or proteomic studies have also been conducted in the same in vitro cell experiment in some cases...

Diabetic retinopathy(DR)is one of the complications of diabetes which could cause severe vision loss. Retinal ganglion cell(RGC)injury has been confirmed prior to micro-vascular damage. Over the past few decades, a number of animal and clinical studies have confirmed that RGC impairment leads to an early deterioration of vision in DR. Inhibition of aldose reductase (AR), advanced glycation end product (AGE), oxidative stress, glutamate toxicity, and an inflammatory response may play important roles in protecting RGCs in DR...
