In this study, we report the directed assembly of hydrogel blocks mediated by electrostatic interactions. We compared two different assembly mechanisms, one mediated by microgel particles and another mediated by direct interaction between oppositely charged blocks. The system consisted in hydrogel blocks made of an interpenetrated network of (hydroxyethyl)methacrylate-poly(ethyleneglycol)dimethacrylate (HEMA-PEGDMA) and either positively charged polyethyleneimine (PEI) or negatively charged hyaluronic acid (HA)...

BACKGROUND: Botulinum toxin type A remains the most popular nonsurgical aesthetic treatment worldwide. Previous consensus statements have focused on Caucasians and on Koreans as generally representative of Asians. However, indications and dosages vary among different ethnic groups. This publication reports the results of a multidisciplinary, pan-Asian consensus focusing on incobotulinumtoxinA. METHODS: A consensus group of plastic surgeons and dermatologists from Asia, Europe, and the United States convened for a live meeting in Asia, followed by a questionnaire-based Delphi procedure...

Degradable poly(2-hydroxyethyl methacrylate) hydrogels were prepared from a linear copolymer (Mw = 49 kDa) of 2-hydroxyethyl methacrylate (HEMA), 2-(acethylthio)ethyl methacrylate (ATEMA), and zwitterionic 2-methacryloyloxyethyl phosphorylcholine (MPC). The deprotection of ATEMA thiol groups by triethylamine followed by their gentle oxidation with 2,2'-dithiodipyridine resulted in the formation of reductively degradable polymers with disulfide bridges. Finally, a hydrogel 3D structure with an oriented porosity was obtained by gelation of the polymer in the presence of needle-like sodium acetate crystals...

Chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma (SLL) are different manifestations of the same disease and managed in much the same way. The advent of novel CD20 monoclonal antibodies led to the development of effective chemoimmunotherapy regimens. More recently, small molecule inhibitors targeting kinases involved in a number of critical signaling pathways and a small molecule inhibitor of the BCL-2 family of proteins have demonstrated activity for the treatment of patients with CLL/SLL. These NCCN Guidelines Insights highlight important updates to the NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for CLL/SLL for the treatment of patients with newly diagnosed or relapsed/refractory CLL/SLL...

The Neu-Laxova syndrome is a rare autosomal recessive condition associated with neuro-ectodermal abnormalities and other patterns of severe malformations leading to prenatal or early postnatal lethality. Association with kyphosis is an extremely rare finding. A fetus born from a 25-year-old gravida at 30 weeks gestation was diagnosed with Dandy Walker syndrome with severe intrauterine growth restriction on ultrasonography. On post-mortem examination after termination of pregnancy, the fetus showed facial dysmorphology with microcephaly, smooth shiny skin and kyphosis...

Many studies have shown the role of agriculture in the selection and spread of resistance of Anopheles gambiae s.l. to insecticides. However, no study has directly demonstrated the presence of insecticides in breeding sources as a source of selection for this resistance. It is in this context that we investigated the presence of pesticide residues in breeding habitats and their formal involvement in vector resistance to insecticides in areas of West Africa with intensive farming. This study was carried out from June to November 2013 in Dano, southwest Burkina Faso in areas of conventional (CC) and biological cotton (BC) growing...

Abnormalities in resting and event-related brain oscillations are known to be associated with cognitive deficits in schizophrenia. Transcranial alternating current stimulation (tACS) modulates these rhythms across the neuronal circuits and could have a potential therapeutic role in psychiatric disorders. In this report, we describe, for the first time, application of online tACS in a schizophrenia patient with working memory deficits. This case report supports the feasibility and potential utility of online tACS in schizophrenia, which needs further systematic research...

BACKGROUND: The surfaces of the bones in the knee are covered with articular cartilage, a rubber-like substance that is very smooth, allowing frictionless movement in the joint and acting as a shock absorber. The cells that form the cartilage are called chondrocytes. Natural cartilage is called hyaline cartilage. Articular cartilage has very little capacity for self-repair, so damage may be permanent. Various methods have been used to try to repair cartilage. Autologous chondrocyte implantation (ACI) involves laboratory culture of cartilage-producing cells from the knee and then implanting them into the chondral defect...

BACKGROUND: Cyclooxygenase (COX-2) inhibitors have been developed to provide better anti-inflammatory and analgesic efficacy than those of traditional NSAIDs. Several compounds having selective COX-2 inhibitors such as SC-558, Celecoxib, Rofecoxib, Valdecoxib and Etoricoxib are marketed as new generation NSAIDs and block the production of prostaglandins (PGs) in inflammatory cells. New anti-inflammatory dynamic agents with improved potency and safety profile are still needed. OBJECTIVE: As a part of our continuation research work towards the synthesis of anti-inflammatory agents, the synthesis of N-substituted aryl/heteroaryl-pyrazole-1yl benzene sulfonamide (Celecoxib) derivatives, and evaluated their anti-inflammatory activity in both methods in vitro and in vivo, and molecular docking study on COX-2 enzyme will be discussed in this study...

DDE (1,1-bis-(4-chlorophenyl)-2,2-dichloroethene), which is a commonly used pesticides in agriculture, has harmful effects on human health. Therefore, the removal of this substance from the drinking water and the soil is essential. Since DDT (1,1″-(2,2,2-Trichloroethane-1,1-diyl) bis(4-chlorobenzene)) is derivation of DDE, the presence of DDT can be monitored by the detection of DDE present in the environment. Herein, we report on the development of aspartic acid-incorporated poly(2-hydroxyethyl methacrylate-L-aspartic acid) [poly(HEMA-MAsp)] cryogel for the removal of DDE from aqueous solutions for the first time in the literature...
