The relation between test conditions such as medium composition or pH on silver nanoparticle (AgNP) behavior and its link to toxicity is one of the major topics in nanoecotoxicological research in the last years. In addition, the adaptation of the ecotoxicological standard tests for nanomaterials is intensely discussed to increase comparability and reliability of results. Due to the limitation of test material production volumes and the need for high-throughput screening, miniaturization has been proposed for several test designs...

While eye drops account for the majority of ophthalmic formulation for drug delivery, their efficiency is limited by rapid pre-corneal loss. In this study, we investigate nanogel suspensions in order to improve the topical ocular therapy by reducing dosage and frequency of administration. We synthesized self-assembling nanogels of 140 nm by grafting side chains of poly(N-tert-butylacrylamide) (PNtBAm) on methylcellulose via cerium ammonium nitrate. Successful grafting of PNtBAm onto methylcellulose (MC) was confirmed by both NMR and ATR...

BACKGROUND: The membrane processes are interesting and economical techniques for reuse of municipal and industrial wastewater as well as seawater desalination. However their drawbacks can be resumed in the fouling and biofouling due to the deposition and adsorption phenomenon of the components and the development of biofilm on membrane surface. Several studies have focused on the effect of the incorporation of nanoparticles in polymeric membrane matrix on the biofouling properties. Few relevant patents to the topic have been reviewed and cited...

The most common causes of umbilical discharge in infancy are infection and umbilical granuloma that may be treated by antibiotics and topical application of silver nitrate subsequently. If the umbilical discharge persists or if there is any abnormal discoloration around the umbilicus, it is important to investigate for underlying congenital abnormality that may be cured by surgical intervention. Unusual presentation of omphalomesenteric duct cyst has been reported in literature. We report, for the first time as far as our search is concerned, a case of a 16-month-old infant who presented initially with persistent umbilical discharge and finally with bruising around the umbilicus in keeping with Cullen's sign...

The long-range influence of ions in solution on the water hydrogen-bond (H-bond) network remains a topic of vigorous debate. Recent spectroscopic and theoretical studies have, for the most part, reached the consensus that weakly coordinating ions only affect water molecules in the first hydration shell. Here, we apply ultrafast broadband two-dimensional infrared (2D IR) spectroscopy to aqueous nitrate and carbonate in neat H2O to study the solvation structure and dynamics of ions on opposite ends of the Hofmeister series...

Effective topical therapy of cutaneous fungal diseases requires the delivery of the active agent to the target site in adequate concentrations to produce a pharmacological effect and inhibit the growth of the pathogen. In addition, it is important to determine the concentration of the drug in the skin in order to evaluate the subsequent efficacy and potential toxicity for topical formulations. For this purpose, an anhydrous gel containing sertaconazole nitrate as a model drug was formulated and the amount of the drug in the skin was determined by in vitro tape stripping...

Mitigation of arsenic (As) pollution is a topical environmental issue of high R&D priority. The present investigation was carried out to isolate As resistant endophytes from the roots of Indian ecotype Pteris vittata and characterize their As transformation and tolerance ability, plant growth promoting characteristics and their role to facilitate As uptake by the plant. A total of 8 root endophytes were isolated from plants grown in As amended soil (25 mg As kg(-1)). These isolates were studied for minimum inhibitory concentration (MIC), arsenite As(III) - arsenate As(V) transformation ability, plant growth promoting (PGP) characteristics through siderophore, indole acetic acid (IAA) production, phosphatase, ACC deaminase activity, and presence of arsenite oxidase (aox) and arsenite transporter (arsB) genes...

l-Arginine is the common substrate for nitric oxide synthases (NOS) and arginase. Whereas the contribution of NOS to collateral artery growth (arteriogenesis) has been demonstrated, the functional role of arginase remains to be elucidated and was topic of the present study. Arteriogenesis was induced in mice by ligation of the femoral artery. Laser Doppler perfusion measurements demonstrated a significant reduction in arteriogenesis in mice treated with the arginase inhibitor nor-NOHA (N(ω)-hydroxy-nor-arginine)...
