Cerebral amyloid angiopathy (CAA) is characterized by the pathologic deposition of amyloid-beta within cortical and leptomeningeal arteries, arterioles, capillaries and, in rare cases, the venules of the brain. It is often associated with the development of lobar intracerebral hemorrhages but may cause other neurologic symptoms or be asymptomatic. Magnetic resonance imaging characteristics, such as lobar microbleeds, support a diagnosis of CAA and assist with hemorrhage risk assessments. Immunosuppressants are used to treat rarer inflammatory forms of CAA...

BACKGROUND: Chronic respiratory diseases, whose one of the hallmarks is oxidative stress, are still incurable and need novel therapeutic tools and pharmaceutical agents. The phenolic compounds contained in grape are endowed with well-recognized anti-oxidant, anti-inflammatory, anti-cancer, and anti-aging activities. Considering that natural anti-oxidants, such as proanthocyanidins, have poor water solubility and oral bioavailability, we have developed a drug delivery system based on solid lipid nanoparticles (SLN), apt to encapsulate grape seed extract (GSE), containing proanthocyanidins...

Crocus sativus is a spice with various pharmacological properties. Crocin, picrocrocin, and safranal are the main compositions of saffron that have recently been considered in the therapy of many diseases. High-performance liquid chromatography analysis revealed presence of these compounds in our saffron extract. This study was carried out to evaluate the effect of saffron on burn wound healing at an in vivo model. Saffron was topically applied on burn wounds in rats; the percentage of wound closure, wound contraction, and the levels of main cytokines and growth factors were measured...

The optimal management of recurrent painful episodes in individuals living with sickle cell disease (SCD) remains unclear. Currently, the primary treatment for these episodes remains supportive, using fluids and intravenous opioid and anti-inflammatory medications. Few reports have described the use of adjunct subanesthetic doses of ketamine to opioids for treatment of refractory pain in SCD. This article reports a retrospective case series of five patients admitted to the intensive care unit (ICU) with prolonged vaso-occlusive episodes (VOEs)...

Fundamental cures of central nervous system (CNS) diseases are rarely achieved due to the low regenerative ability of the CNS. Recently, cell-based therapy using mesenchymal stem cells (MSCs) has been explored as effective treatments for CNS diseases. Among the various tissue-derived MSCs, we have isolated human cranial bone-derived MSCs (cMSCs) in our laboratory. In addition, we have focused on simulated microgravity (MG) as a valuable culture environment of MSCs. However, the detailed mechanisms underlying functional recovery from the transplantation of MSCs cultured under MG conditions remain unclear...

Despite of tremendous development in CNS research, current treatment is suboptimal especially in severe mental disorders. In medicine, there are two main methods of improving the healthcare provided: seeking new treatment procedures and perfecting (optimizing) the existing ones. Optimization of treatment includes not only practical tools such as therapeutic drug monitoring, but also implementation of general trends into the clinical practice. New pharmacological options include drugs aimed at other than monoaminergic systems and old drugs used before the psychopharmacological era...

Renal fibrosis is the final manifestation of various chronic kidney diseases, and no effective therapy is available to prevent or reverse it. Celastrol, a triterpene that derived from traditional Chinese medicine, is a known potent anti-fibrotic agent. However, the underlying mechanisms of action of celastrol on renal fibrosis remain unknown. In this study, we found that celastrol treatment remarkably attenuated unilateral ureteral obstruction (UUO)-induced mouse renal fibrosis. This was evidenced by the significant reduction in tubular injury; collagen deposition; accumulation of fibronectin, collagen I, and α-smooth muscle actin; and the expression levels of pro-fibrotic factors Vim, Cola1, and TGF-β1 mRNA, as well as inflammatory responses...

BACKGROUND: Immune activation, specifically activation of macrophages and resident microglia, leading to inflammation is a key component in the progression of spinal cord injury (SCI). Macrophages/microglia exist in two states-the classically activated M1 phenotype that confers pro-inflammatory effects or the alternatively activated M2 phenotype that confers anti-inflammatory effects. Ecto-5'-nucleotidase (CD73) is an immunosuppressive molecule intricately involved in adaptive and innate immune responses and is able to dephosphorylate AMP to adenosine...

Colorectal cancer (CRC) is a leading cause of cancer-related mortality worldwide. Although CRC has been comprehensively characterized at the molecular level, the tumor heterogeneity hinders the identification of reliable diagnostic, prognostic and predictive biomarkers. Molecular stratification of CRC is based on prevalent gene mutations and transcription profiles but its significance for clinical practice remains obscure. Indeed, activating mutations in the genes KRAS, NRAS and BRAF are the only predictive biomarkers for anti-EGFR antibody therapy routinely tested the clinic for advanced stages of CRC...

Glioblastoma tumors (GBM) are very heterogeneous, being comprised of several cell subtypes, including glioblastoma stem cells (GSC). These tumors have a high rate of recurrence after initial treatment and one of the most prevalent theories to explain this is the cancer stem cell theory, which proposes that glioblastomas arise from mutations that transform normal neural stem cells (NSC) into GSC, which are highly resistant to oxidative stress and anti-cancer therapies. Sulindac is a non-steroidal anti-inflammatory drug (NSAID) that has been shown to protect the normal cells against oxidative damage by initiating a preconditioning response, but selectively sensitizes several cancer cell lines to agents that affect mitochondrial respiration, resulting in enhanced killing of the cancer cells...

REVIEW
Jihye Park, Jae Hee Cheon
Intestinal Behçet's disease is a rare, immune-mediated chronic intestinal inflammatory disease; therefore, clinical trials to optimize the management and treatment of patients are scarce. Moreover, intestinal Behçet's disease is difficult to treat and often requires surgery because of the failure of conventional medical treatment. Administration of anti-tumor necrosis factor α, a potential therapeutic strategy, is currently under active clinical investigation, and evidence of its effectiveness for both intestinal Behçet's disease and inflammatory bowel diseases has been accumulating...

Background: Although anti-adhesion therapies are a novel mainstay in the treatment of inflammatory bowel diseases (IBDs), the mechanisms controlling integrin-dependent gut homing are poorly elucidated, and the available techniques for translational functional investigations are limited. Methods: We used dynamic adhesion assays to study adhesion of CD4+ T cells, CD8+ T cells, CD19+ B cells, and granulocytes to the addressins MAdCAM-1, VCAM-1, and ICAM-1. The effects of vedolizumab, natalizumab, etrolizumab-s, anti-CD11a, and anti-CD18 antibodies were explored...

Background: Previous reports have shown differences in phenotypes among black patients with inflammatory bowel disease (IBD) compared with other racial groups, but prior studies were limited by small numbers of black patients and cross-sectional analyses. We used data from the Sinai-Helmsley Alliance for Research Excellence cohort to compare phenotypes and treatment patterns of black and white patients with IBD in a prospective study. Methods: We compared phenotypes, IBD-specific therapies, and health care utilization among black and white patients with IBD...

Epithelial-mesenchymal Transition (EMT) and migration play an important role in tumor progression, and lipoxin (LX), the 'stop signal' for inflammation, has been studied in basic research for its anti-inflammatory or inflammatory pro-resolving properties. Here, in the in vitro experiment, we showed that LXA4 could inhibit the EMT and migration in phorbol myristate acetate (PMA) or activated conditioned medium (ACM)-stimulated Hep3B cells by downregulation of integrin-linked kinase (ILK), a pseudokinase in cytoplasm and these effects were via inhibiting the phosphorylation of Akt and GSK3β...

Topical analgesics are effective and alternative means to systemic therapy, often minimizing the adverse drug effects and complications of systemic analgesic use. Despite the number of available topical analgesics, there is little direction provided in practice guidelines on their appropriate use and little is known about patterns of their prescribing. To begin understanding these knowledge gaps, we sought provider perspectives on topical analgesic use at a large academic medical center. This electronic survey seeks to explore the perceptions and prescription patterns of topical analgesics among prescribers in a large academic medical center, where the availability of topical analgesics varies...

Saeed Akkad, Christopher J Serpell
As more evidence emerges supporting the possibility that nonsteroidal anti-inflammatory drugs, especially aspirin (acetyl salicylic acid), might have a role in the prevention and management of certain types of cancer, there have been several attempts to fabricate salicylic acid-based polymers that can be employed in the targeted therapy of tumors. The primary disadvantage so far has been in use of nontherapeutic polymeric backbones that constitute the majority of the therapeutic particle's size. The focus of this research is the creation of a biodegradable polymer consisting only of salicylic acid, and its use as the main building block in targeted nanotherapeutics that would consequently provide both high local dose and sustained release of the active moiety...
