Analysis of endonasal sinus surgery in a private outpatient setting in a tropical environment: A STROBE analysis.

Objectives: To evaluate results and failure factors in endonasal surgery in a private outpatient setting in a tropical environment.

Material And Method: A single-center observational study included 337 patients consecutively undergoing endonasal surgery in a private hospital on Réunion Island, a French overseas administrative Département in the Indian Ocean between 2019 and 2021. The main objective was to assess the success rate of the outpatient pathway.

Concentrates of DHA from fish oil by selective esterification of cholesterol by immobilized isoforms of lipase from Candida rugosa.

Two lipases (Lip A and Lip B), were purified from a commercial lipase preparation produced by Candida rugosa and partially characterized. The purified lipases were immobilized on Duolite A 568 and used in the selective esterification of cholesterol with free fatty acids from sardine fish oil. The results showed that Lip A and Lip B preferentially esterified saturated and monounsaturated fatty acids allowing a 3.

Purification and characterization of an extracellular lipase from a thermophilic Rhizopus oryzae strain isolated from palm fruit.

We have isolated a lipolytic strain from palm fruit that was identified as a Rhizopus oryzae. Culture conditions were optimized and highest lipase production amounting to 120 U/ml was achieved after 4 days of cultivation. The extracellular lipase was purified 1200-fold by ammonium sulfate precipitation, sulphopropyl-Sepharose chromatography, Sephadex G 75 gel filtration and a second sulphopropyl-Sepharose chromatography.
