Environmental tolerance of a species has been shown to correlate positively with its geographical range. On the Ordos Plateau, three Caragana species are distributed sequentially along the precipitation gradient. We hypothesized that this geographical distribution pattern is related to environmental tolerances of the three Caragana species during seed germination and seedling emergence stages. ...

Rhizobia are soil bacteria with the capacity to induce nitrogen-fixing nodules on the roots or stems of legume plants. A total of 40 bacterial isolates from the root nodules of Caragana microphylla growing in desert soil in Ningxia, China, were analyzed for genetic diversity and phylogenetic position. These isolates were classified into 7 types of 16S ribosomal DNA (rDNA) using polymerase...

Agilent Captiva Premium PES syringe filters are evaluated and compared to other suppliers’ PES and PVDF syringe filters for the risk of losing protein during filtration. Captiva Premium PES syringe filters demonstrate low protein binding with excellent recovery for biological samples, especially for ‘sticky’ proteins at low concentrations. In addition, an assessment of filter extractables on LC...

BACKGROUND Sterile syringe access is a critical component of HIV prevention programs. Although retail pharmacies provide convenient outlets for syringe access, injection drug users (IDUs) may encounter barriers to syringe purchase even where purchase without a prescription is legal. We sought to obtain an objective measure of syringe access in Tijuana, Mexico, where IDUs report being denied or ...

From the petroleum ether extract of the aereal part of Condalia microphylla Cav, hydrocarbons, sterols, alcohols, and fatty acids were isolated. From fruits of the same plant anthocyanins were also isolated and characterized by chromatographic and spectroscopic methods. Introduction Condalia microphylla Cav. Species belongs to the Ramnaceae family, and its common name is “Piquillín”. It general...

The authors present in this brief note a technique to facilitate the introduction of high viscosity bone cement into a cement syringe for retrograde high pressure cementing during total hip or revision knee arthroplasty. The nozzle part of the syringe is connected to the suction device used intra-operatively, to achieve a negative pressure in the syringe. Introduction of the cement into the syr...

Fit the nozzle of a 4 oz. or 8 oz. glass syringe into a Jacques' catheter of the required size and charge the catheter and the syringe with weak iodine solution. Introduce the catheter into the bottom of the cavity to be drained. Inject the solution slowly into it and draw the contents of the cavity into the syringe. Take the syringe out, leaving the catheter still in the cavity, and throw out ...

Objective(s): Our present study sought to evaluate hepatoprotective and antioxidant effects of methanol extract of Azolla microphylla phytochemically synthesized gold nanoparticles (GNaP) in acetaminophen (APAP) - induced hepatotoxicity of fresh water common carp fish.Materials and Methods: GNaP were prepared by green synthesis method using methanol extract of Azolla microphylla.  Twenty four f...
