Rheumatoid arthritis(RA) is a chronic autoimmune disease, belonging to the "Arthromyodynia (Bi Zheng)" category in traditional Chinese medicine. However, the ethnomedicine has a unique understanding of RA, with a long-term clinical experience accumulation and significant efficacy in the treatment of RA, and it has now become one of the important means in treatment of RA. On the basis of literature research, the understanding of RA and commonly used Tibetan medicine, Mongolian medicine, Hui medicine and other herbs and preparations were reviewed in this paper, with the aim of providing a reference for its clinical treatment of RA and research and development of innovative drugs...

Current analgesic therapies for treatment of neuropathic pain are unsatisfactory. Neuropathic pain is, therefore, undertreated and there is a significant need for a better pharmacotherapy. Increasing evidence indicate that histone deacetylation is a critical step in nerve injury pain. To obtain an innovative treatment for the management of neuropathic pain, we investigated the pharmacological effects produced by the new histone deacetylase (HDAC)-1 selective inhibitor, LG325, in a mouse model of trauma-induced peripheral mononeuropathy provoked by spared nerve injury (SNI)...

Innovative drug delivery technologies based on smart hydrogels for localized on-demand drug delivery had aroused great interest. To acquire smart UV-crosslinkable chitosan hydrogel for NIR-triggered localized on-demanded drug release, a novel UV-crosslinkable and thermo-responsive chitosan was first designed and synthesized by grafting with poly N-isopropylacrylamide, acetylation of methacryloyl groups and embedding with photothermal carbon. The UV-crosslinkable unit (methacryloyl groups) endowed chitosan with gelation via UV irradiation...

Highly hydrophilic and biocompatible nanocarriers based on polysaccharide hydrogels (nanohydrogels, NHs) were shown to be promising systems for drug delivery applications. Following the idea of these emerging drug carriers, the aim of the present work was to develop self-assembled hydrogel nanoparticles based on amphiphilic derivatives of hyaluronic acid (HA) and riboflavin (Rfv), synthesized by "click" Copper(I)-catalyzed Azide-Alkyne Cycloaddition (CuAAC) reaction. The obtained amphiphilic product (HA-c-Rfv) was able to form nanohydrogels in aqueous environments, in particular by applying an innovative autoclave-based method...

The present contribution aims at describing the fabrication of coacervates in the nano-size range starting from a 1-deoxylactit-1-yl chitosan (in this manuscript termed as CTL60) and the multivalent anion tripolyphosphate (TPP). Colloidal coacervates have been obtained for precise values of the molar ratio of TPP to CTL60 repeating unit. Coacervation is ensured only at pH 4.5 and not at 7.4, thus demonstrating the key role of electrostatic interactions in the stabilization of the coacervates. At a variance with chitosan, CTL60 favors the formation of highly homogeneous coacervates with very low values of the polydispersity index (PDI)...

REVIEW
Olga Genilloud
Covering: 2006 to 2017Actinomycetes have been, for decades, one of the most important sources for the discovery of new antibiotics with an important number of drugs and analogs successfully introduced in the market and still used today in clinical practice. The intensive antibacterial discovery effort that generated the large number of highly potent broad-spectrum antibiotics, has seen a dramatic decline in the large pharma industry in the last two decades resulting in a lack of new classes of antibiotics with novel mechanisms of action reaching the clinic...

Rationale The early detection of primary tumours and metastatic disease is vital for successful therapy and is contingent upon highly specific molecular markers and sensitive, non-invasive imaging techniques. We hypothesized that the accumulation of activated platelets within tumours is a general phenomenon and thus represents a novel means for the molecular imaging of cancer. Here we investigate a unique single chain antibody (scFv), which specifically targets activated platelets, as a novel biotechnological tool for molecular imaging of cancer...

Health care professionals involved in the clinical management of children have long appreciated the limited number of therapies suitably evaluated for their optimal use in the pediatric population. In the past century, advances in regulatory policy significantly evolved adult drug evaluation. The scarcity of available patient populations, practical complexities of drug development research, and minimal financial returns have hampered pharmaceutical investment in the study of therapies for children. More recently, pediatric policy and legislation in the United States and Europe have instituted a system of obligations and incentives to stimulate investment in pediatric drug development...

The development of in vitro protein misfolding amplification assays for the detection and analysis of abnormally folded proteins, such as proteinase K resistant prion protein (PrP(res)) was a major innovation in the prion field. In prion diseases, these types of assays imitate the pathological conversion of the cellular PrP (PrP(C)) into a proteinase resistant associated conformer or amyloid, called PrP(res). Areas covered: The most prominent protein misfolding amplification assays are the protein misfolding cyclic amplification (PMCA), which is based on sonication and the real-time quaking-induced conversion (RT-QuIC) technique based on shaking...

Amyotrophic lateral sclerosis (ALS) is a progressive fatal neurodegenerative disease that is characterized by the death of motor neurons in the spinal cord, brain stem, and motor cortex that are responsible for voluntary movement. For unknown reasons, military veterans are approximately twice as likely as the public to be given a diagnosis of ALS. Currently, there is no cure for ALS. The only US Food and Drug Administration-approved disease-modifying medication is riluzole (Rilutek), which may slow ALS progression but only minimally increases survival time...

Applications of omics systems biology technologies have enormous promise for radiology and diagnostics in surgical fields. In this context, the emerging fields of radiomics (a systems scale approach to radiology using a host of technologies, including omics) and pharmacometabolomics (use of metabolomics for patient and disease stratification and guiding precision medicine) offer much synergy for diagnostic innovation in surgery, particularly in neurosurgery. This synthesis of omics fields and applications is timely because diagnostic accuracy in central nervous system tumors still challenges decision-making...

Depression, anxiety and other affective disorders are globally widespread and severely debilitating human brain diseases. Despite their high prevalence and mental health impact, affective pathogenesis is poorly understood, and often remains recurrent and resistant to treatment. The lack of efficient antidepressants and presently limited conceptual innovation necessitate novel approaches and new drug targets in the field of antidepressant therapy. Areas covered: Herein, the authors discuss the emerging role of neuro-immune interactions in affective pathogenesis, which can become useful targets for CNS drug discovery, including modulating neuroinflammatory pathways to alleviate affective pathogenesis...

Cancer metastasis accompanies irreversible proteolysis. Malignant cells that abnormally express extracellular proteases usually lead to a poor outcome during cancer progression. The development of protease-activated drugs is an important goal. Moreover, the specific proteolytic mechanism can be used as a diagnostic strategy. Currently, nanotechnology for use in medication has been extensively developed to exploit the physical and chemical properties of nanoparticles. For example, to improve the efficacy of cancer therapy drugs, targeted delivery has been attempted by combining a targeting ligand with a nanoparticle...
