The prevalence of non-alcoholic fatty liver disease (NAFLD) has sharply increased over the past several decades in Korea. In most cases of NAFLD, metabolic stress and cellular apoptosis are often driven by metabolic abnormality, eventually leading to inflammation and fibrosis . Along with a dramatic surge in the obesity epidemic, 10-20% of NAFLD patients ultimately progress to non-alcoholic steatohepatitis (NASH), a precursor to cirrhosis and hepatocellular carcinoma, as well as multi-organ systemic diseases...

A panel of experts drawn from neurology, psychiatry, geropsychiatry, geriatrics, and pharmacy representatives of 3 health plans convened in New York City on July 30, 2016, with the objective of sharing opinions, ideas, and information regarding the optimal management of Parkinson's disease psychosis (PDP). Three key points emerged from the discussion: (1) Because of the nature of Parkinson's disease and PDP, finding appropriate treatment can prove challenging; (2) emerging therapies may present an opportunity for effective disease management; and (3) moving forward, provider and patient education regarding PDP and available treatment options is essential for well-managed symptoms and better quality of life...

Asthma is an airway disease characterised by chronic inflammation with intermittent or permanent symptoms including wheezing, shortness of breath, chest tightness, and cough, which vary in terms of their occurrence, frequency, and intensity. The most common associated feature in the airways of patients with asthma is airway inflammation. In recent decades, efforts have been made to characterise the heterogeneous clinical nature of asthma. The interest in improving the definitions of asthma phenotypes and endotypes is growing, although these classifications do not always correlate with prognosis nor are always appropriate therapeutic approaches...

SIGNIFICANCE: Pyridine dinucleotides, NAD and NADP, were discovered over 100 years ago as necessary cofactors for fermentation in yeast extracts. Since that time, these molecules have been recognized as fundamental players in a variety of cellular processes, including energy metabolism, redox homeostasis, cellular signaling, and gene transcription, among many others. Given their critical role as mediators of cellular responses to metabolic perturbations, it is unsurprising that dysregulation of NAD and NADP metabolism has been associated with the pathobiology of many chronic human diseases...

Antisense oligonucleotides (ODNs) are therapeutic molecules that hybridize to complementary target mRNA sequences. To further overcome the poor cellular uptake of ODNs, we proposed a novel strategy to deliver ODNs by conjugating the anti-influenza A virus (IAV) ODN with a peptide showing high affinity to the haemagglutinin (HA) on the surface of IAV particles or the IAV infected host cells. The HA-specific binding peptides were selected by phage display and the individual binding clones are characterized by DNA sequencing, and the selected phage was further assayed by ELISA...

PURPOSE OF REVIEW: Osteogenesis is a complex process involving the specification of multiple progenitor cells and their maturation and differentiation into matrix-secreting osteoblasts. Osteogenesis occurs not only during embryogenesis but also during growth, after an injury, and in normal homeostatic maintenance. While much is known about osteogenesis-associated regulatory genes, the role of microRNAs (miRNAs), which are epigenetic regulators of protein expression, is just beginning to be explored...

Life is mechanobiological: mechanical stimuli play a pivotal role in the formation of structurally and functionally appropriate body templates through mechanobiologically-driven cellular and tissue re/modeling. The body responds to mechanical stimuli engendered through physical movement in an integrated fashion, internalizing and transferring forces from organ, through tissue and cellular length scales. In the context of rehabilitation and therapeutic outcomes, such mechanical stimuli are referred to as mechanotherapy...

MicroRNAs are important cellular mediators of mRNA degradation and translation repression, which in turn can have an impact on various processes and, if their function is perturbed, can cause disease. Here, we summarise the recent manuscript by Zhong et al., which explores microRNA-146a and how it may play an indirect yet vital role in the proliferation of osteoarthritis (OA) chondrocytes. The data presented by the authors could have important implications for future OA therapies.

BACKGROUND: Retinoblastoma (Rb) is the most common primary intraocular tumor in children. Local treatment of the intraocular disease is usually effective if diagnosed early; however advanced Rb can metastasize through routes that involve invasion of the choroid, sclera and optic nerve or more broadly via the ocular vasculature. Metastatic Rb patients have very high mortality rates. While current therapy for Rb is directed toward blocking tumor cell division and tumor growth, there are no specific treatments targeted to block Rb metastasis...

Cancer stem cells (CSCs) are a subpopulation of cancer cells that share properties of embryonic stem cells like pluripotency and self-renewal and show increased resistance to chemo- and radiotherapy. Targeting CSC, rather than cancer cells in general, is a novel and promising strategy for cancer treatment. Novel therapeutic approaches, such as photodynamic therapy (PDT) have been investigated. A promising group of phototherapeutic agents are reactive intermediates - quinone methides (QMs). This study describes preparation of QM precursor, 2-hydroxy-3-hydroxymethylanthracene (2) and a detailed photochemical and photobiological investigation on similar anthracene derivatives 3 and 4...

There have been major recent advancements in the understanding and management of multiple myeloma which in turn has led to unprecedented survival outcomes for patients. Diagnostic and response criteria have been recently revised. Our understanding of clonal progression, evolution, and clonal tides will inform therapeutic choices and appropriate treatment for patients. Response rates to initial induction with modern triplet therapies containing proteasome inhibitors and immunomodulators have made this approach the global standard for initial treatment...

Pancreatic cancer is a common cause of cancer-related mortality. Omental spread is frequent and usually represents an ominous event, leading to patient death. Omental metastasis has been studied in ovarian cancer, but data on its role in pancreatic cancer are relatively scarce and the molecular biology of this process has yet to be explored. We prepared tissue explants from human omental fat, and used conditioned medium from the explants for various in vitro and in vivo experiments designed to evaluate pancreatic cancer development, growth, and survival...

The positive role of platelet gel (PG) in tissue regeneration is well known, however, other characteristics of PG still remain to be determined. We investigated cellular and molecular changes in cultured human retinal pigment epithelial (hRPE) cells when treated with different concentrations of PG named PG1, PG2, and PG3. hRPE cells were isolated from donor eyes of two newborn children, within 24 hours after their death. The cells were treated with three concentrations of PG for 7 days: 3 × 104/ml (PG1), 6 × 104/ml (PG2), and 9 × 104/ml (PG3)...

The wonderful chemical structures and characteristics of low-dimensional carbon materials have exciting applications in life sciences. In the present study, we developed a facile strategy to conjugate C60 with graphene via host-guest chemistry for targeted phototherapy. A versatile carrier based on folic acid-functionalized graphene (GO-FA) and comprising γ-cyclodextrin (γ-CD) at its surface was assembled via π-π interaction, creating hybrid structures with drug storage and tumor targeting properties. This γ-CD-modified graphene (GO-FA/Py-γ-CD) is capable of hosting pristine C60 molecules for the fabrication of a GO-FA/Py-γ-CD/C60 nanohybrid...

Rapid advances in Ca(2+) imaging techniques enable us to simultaneously monitor the activities of hundreds of astrocytes in the intact brain, thus providing a powerful tool for understanding the functions of both host and engrafted astrocytes in sensory processing in vivo. These techniques include both improved Ca(2+) indicators and advanced optical recording methods. Astrocytes in multiple cortical and sub-cortical areas are able to respond to the corresponding sensory modalities. These sensory stimuli produce astrocytic Ca(2+) responses through different cellular mechanisms...

Carbonic anhydrase IX has emerged as a promising target for cancer therapy. It is highly up-regulated in hypoxic regions and mediates pH regulation critical for tumor cell survival as well as extracellular acidification of the tumor microenvironment which promotes tumor aggressiveness via various mechanisms, such as augmenting metastatic potential. Therefore, the aim of this study was to analyze the complex interdependency between CA IX and the tumor microenvironment in prostate tumor cells in concern of potential therapeutic implications...

With the introduction of next-generation sequencing, the genetic landscape of the complex group of B-cell lymphoid malignancies has rapidly been unravelled in recent years. This has provided important information about recurrent genetic events and identified key pathways deregulated in each lymphoma subtype. In parallel, there has been intense search and development of novel types of targeted therapy that 'hit' central mechanisms in lymphoma pathobiology, such as BTK, PI3K or BCL2 inhibitors. In this review, we will outline the current view of the genetic landscape of selected entities: follicular lymphoma, diffuse large B-cell lymphoma, mantle cell lymphoma, chronic lymphocytic leukaemia and marginal zone lymphoma...
