Homodispersed 1.8 nm gold nanoparticles were obtained reproducibly in high yields using the classical Turkevich protocol at a high concentration in a continuous flow capillary reactor. The microfluidic reactor made from commercially available items permitted short mixing, heating and quenching times which are the key parameters of this synthesis.

Suaeda aralocaspica is an annual halophyte in the Amaranthaceae saline deserts of central Asia. This plant has succulent leaves and grape-like fruits a potential horticultural plant. To obtain efficient sterilization method optimal culture conditions, two types seeds produced from single S. were treated with 75% ethanol for different time durations first, then sodium hypochlorite (NaClO) or mer...

BACKGROUND AND PURPOSE Hyperglycemia after acute ischemic stroke (AIS) is associated with poor outcomes. However, there is no consensus as to the optimal method for glycemic control. We designed an insulin infusion protocol for aggressive glucose control and investigated its efficacy and safety. METHODS We applied our protocol to patients within 48 hours after AIS or transient ischemic attack...

Wildfires produce smoke, which can then encounter wine grapes, causing the fruit to absorb smoke-related volatile organic compounds. These compounds impact sensorial profiles of resulting wines, introducing an uncharacteristic smokey flavor and ashy finish. Since these off-flavor attributes are observed have longer-lasting perception, a proper inter-stimulus protocol is necessary ensure accurat...

The regenerative endodontic procedure (REP) is an alternative solution for treatment of permanent teeth with incomplete root apex development. It results in angiogenesis, reinnervation, and further formation. Indications REP include immature necrotic pulp inflammatory lesions the periapical tissues. main contraindications comprise significant destruction tooth tissues a lack patient cooperation...

a capillary electrophoresis method was used for assay of some degradation products of carvedilol. the optimized parameters were as; running buffer 80 mm acetate dissolved in methanol/ethanol mixture (65:35 v/v), applied voltage of 19 kv, temperature is 20 ºc and the wavelength range of 200-350 nm. the results indicate that the proposed ce method could effectively separate carvedilol from its de...

objectives: periodontal pathogens need acidic environments to proliferate in periodontium, and their growth is affected by the salivary flow rate and ph of the mouth. alterations in flow and acidity of saliva have an important effect on oral diseases such as periodontitis. this study was designed to compare salivary ph and flow rate before and after using green tea, black tea and coffee in pati...

BACKGROUND The effect of mouth rinsing with a carbohydrate (CHO) solution on exercise performance is inconclusive with no benefits observed in the fed state. This study examined the effect of CHO mouth rinse or CHO ingestion on performance in 9 moderately trained male cyclists. METHODS Four trials were undertaken, separated by 7 days, in a randomized, counterbalanced design. Each trial includ...
