Lower lateral crural turnover flap combined with alar batten graft for the long-term result of the treatment of alar convexities.

Introduction: Concave lower lateral cartilages not only cause an esthetic defect but can also lead to external nasal valve insufficiency. The objective of this article is to analyze the combination of two well-known surgical techniques: turning over the alar cartilages as well as the addition of grafts in order to obtain satisfying esthetic and functional long term results.

Materials And Methods: From August 2016 to July 2018, 62 rhinoplasties, a combination of both primary and revision cases, were performed at the Rouen University Hospital in France.

Fluorescent Biomolecules Capped ZnSe Quantum Dots and Their Photocatalytic Activities.

The preparation of semiconductor Quantum Dots (QDs) with controllable size, shape and doping remains a biggest challenge, especially the size below 10 nm. To date, only scarce attempts have been made on the synthesis of ZnSe QDs using biomolecule-assisted hydrothermal approach. Hence the current research work examines the influence of some amino acids namely L-cysteine, methionine and tyrosine as stabilizing agents in the synthesis of ZnSe nanocrystals.

Fast glycorrhachia and cerebrospinal fluid protein as predictors of sensory block in anesthesia with subarachnoid Ropivacaine.

Background: Identify if glycorrhachia and cerebrospinal fluid protein could influence the time of sensory block to T10, the duration and the metameric block's level, after a standard dose of Ropivacaine.

Methods: 80 patients, ASA I - III undergoing to transurethral prostate resection with spinal anesthesia in a prospected open study were recruited. A 0.

New C26 delta-lactones from the Dufour's gland of the urticating ant Tetramorium aculeatum.

(6R*)-[(2S*)-2-hydroxyheneicos-12-enyl]-5,6-dihydro-2H-pyran-2-one (1) degree is the major constituent of the secretion of freshly dissected Dufour's gland of the urticating ant Tetramorium aculeatum. In solution, compound 1 is slowly transformed into (1S*,5R*,7S*)-7-(nonadec-10-enyl)-2,6-dioxabicyclo[3.3.

Evaluation of health and productivity of small ruminants in Africa: the example of Senegal.

The authors describe a system of investigation introduced into Senegal in 1983; their purpose is to extend knowledge about the farming of small ruminants and the epidemiological relevance of such farming. The investigations are conducted in the traditional livestock sector by using a multidisciplinary approach. The precision and reliability of the information depend on the recording and processing of data on individual animals.

Endocrine, hematological and immunological changes in surgical patients undergoing general anesthesia.

Some hematological endocrine, and immunological reactions in surgical patients under general anesthesia were studied. While serum cortisol, fT4, T4, rT3 levels increased, TBG, TSH, fT3 and T3 decreased. Cortisol increase and T3 and fT3 decrease were still significant three days after surgery.

Tetraponerines, toxic alkaloids in the venom of the Neo-Guinean pseudomyrmecine antTetraponera sp.

The Neo-Guinean pseudomyrmecine ant,Tetraponera sp. utilizes its modified sting to smear upon enemies a contact poison with strong deterring and toxic properties. The venom, which originates from the poison gland, contains a mixture of eight closely related, alkaloids (tetraponerine-1 to -8).
