  1. 1. Safety and efficacy of intracameral mydriatics in cataract surgery

    Author : Björn Lundberg; Anders Behndig; Charlotta Zetterström; Umeå universitet; []
    Keywords : Ophtalmology; intracameral; mydriatics; pupil; cataract; phacoemulsification; lidocaine; phenylephrine; cyclopentolate; epinephrine; endothelial cell loss; Oftalmiatrik; oftalmiatrik; Ophtalmology;

    Abstract : Background: In order to perform cataract surgery, adequate dilatation of the pupil is essential. This is traditionally achieved by preoperative topical mydriatic eye-drops, commonly cyclopentolate and phenylephrine. This routine has several disadvantages. First, the slow penetration through the cornea delays the onset of mydriasis. READ MORE

  2. 2. Actions of Antimicrobial Peptides and Bacterial Components in Inflammation

    Author : Thorgerdur Sigurdardottir; Anestesiologi och intensivvård; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sepsis; LL-37; M1 protein; S. pyogenes; Toll-like receptors; phenylephrine; nitr1c oxide; antimicrobial peptides;

    Abstract : Antimicrobial peptides are evolutionally ancient parts of the innate immune system and their primary role is to protect us from infections. The human cathelicidin-derived antimicrobial peptide, LL-37, not only possesses broad spectrum antimicrobial activities but is also able to bind and neutralize bacterial lipopolysaccharide (LPS), an important trigger of the widespread inflammatory response contributing to septic shock.

  3. 3. Conctraction-mediating receptors in human peripheral vessels with special reference to veins and lymphatics

    Author : Trygve Sjöberg; Thoraxkirurgi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Human; arteries; veins; lymphatis; contraction; in vitro; in vivo; adrenergic receptors; noradrenaline; cirazoline; phenylephrine; clonidine; calcium antagonists; nifedipine; diltiazem; prostaglandins; thromboxane A2; U-46619; BM-13.505; indomethacin;

    Abstract : By means of a myograph, postjunctional alpha-adrenoceptors were characterized in human superficial epigastric arteries and veins obtained from health subjects. The rank order of potency of subtype selective agonists could not be used for receptor characterization in these vessels, whereas antagonists gave distinct results. READ MORE

  4. 4. Cataract surgery in patients with diabetes mellitus : clinical studies

    Author : Anna Zaczek; Karolinska Institutet; Karolinska Institutet; []
    Keywords : diabetic retinopathy; clinically significant macular edema; miosis; mydriasis; neuropathy; phenylephrine; pilocarpine; visual acuity; laser flare intensity; cataract surgery; phacoemulsification; blood-aqueous barrier; postoperative inflammation; posterior capsule opacification; intraocular lens; Scheimflug camera;

    Abstract : The aim was to evaluate phacoemulsification cataract extraction with small incision and implantation of heparin-coated intraocular lens (IOL) in the capsular bag in patients with diabetes mellitus (DM). The aqueous flare intensity, which reflects the protein concentration in the aqueous humor, was used to evaluate blood-aqueous function in patients with DM type I and type II. READ MORE

  5. 5. Vasopressors and intestinal mucosal perfusion. Studies in cardiac surgical and critically ill patients

    Author : Andreas Nygren; Göteborgs universitet; []
    Keywords : ;

    Abstract : During trauma, surgery and critically illness, splanchnic ischemia and reperfusion damage maythreaten the barrier function of the intestinal mucosa, leading to bacterial translocation, immuneactivation and subsequent development of systemic inflammatory response syndrome. Detection,prevention and treatment of intestinal mucosal hypoperfusion are therefore important forprevention of complications in critically ill patients. READ MORE
