Abstract Standard Carnation flowers (Dianthus caryophyllus cv. Dover) were harvested at the paint brush stage in early morning, pre-cooled 4° C for 6-h then moved under dry conditions to laboratory. Flowers weighted and treated 24-h with silver nanoparticles (AgNPs) 0, 5 or 10 ppm plastic buckets. After pulsing treatments, cut transferred 500 mL glass jars containing 300 of preservation solutio...

PURPOSE Epithelial disorders after eye surgery can result in visual deterioration and patient discomfort. Such disorders may be caused by drug toxicity. In the present study, we evaluated the toxicity of ophthalmic solutions, with or without benzalkonium chloride (BAK) as the preservative, used for postoperative care. METHODS A range of commercially available antibiotic and anti-inflammatory ...

CONTEXT Botulinum A exotoxin is used for various indications, including the treatment of dynamic forehead lines. OBJECTIVE To determine whether injection with botulinum A exotoxin reconstituted with preservative-containing normal saline (isotonic sodium chloride) is less painful than injection with exotoxin that has been reconstituted with preservative-free saline. DESIGN Two arms: (1) retr...

Abstract Carnation (Dianthus caryophyllus ‘Servantes’) is a popular and economically cut flower widely used in the florist industry. However, post-harvest senescence occurs few days limits carnation flowers’ commercialization. Therefore, this research was performed to investigate impact of essential oils such as tea tree oil (TTO), pumpkin seed (PSO), Moringa (MEO), Eucalyptus (EEO), eco-friend...

Green mussels (Perna viridis) are one of the prospective aquatic resources that can be developed into a high-value commodity. Their shells, on other hand, rarely used and discarded; despite fact shells contain chitosan, which as food preservative.The purpose this study is to examine effect chitosan administration from green mussel Sonneratia caseolaris mangrove syrup at various concentrations. ...

We have compared the reactivity to carbachol and high potassium of circular smooth muscle isolated from segments of human colon which was freeze-stored in different preservative solutions for more than one month following surgical resection. Concentration-dependent contractions in response to carbachol were reduced in terms of both their sensitivity (pEC50) and reactivity (Emax), depending on t...

leaf yellowing is a major problem in postharvest of alstroemeria cut flowers. for delaying of leaf yellowing and increasing flower quality a completely randomized factorial design was carried out on the alstroemeria cut flowers (‘fuji’ cultivar). in this research ethanol (0, 2, 4, 6%), ga3 (0, 50, 100, 150 mg/litre) in two methods (pulse and continuous) were investigated on the flower vese life...

Sucralose is a commonly employed artificial sweetener that appears to destabilize protein native structures. This is in direct contrast to the bio-preservative nature of its natural counterpart, sucrose, which enhances the stability of biomolecules against environmental stress. We have further explored the molecular interactions of sucralose as compared to sucrose to illuminate the origin of th...
