We investigated the microbial contamination of suction tubes attached to wall-type suction instrument. Microbial contamination of suction tubes used for endoscopy or sputum suction in wards was examined before and after their disinfection. In addition, disinfection and washing methods for suction tubes were evaluated. Suction tubes (N=33) before disinfection were contaminated with 102-108 colon...

Background: Different types of endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA) techniques are used in clinical practice; the best method in terms of outcome is not standardized. Objectives: To compare diagnostic adequacy of aspirated material, cytopathologic and EUS morphological features among capillary action, suction, and no suction FNA methods. Methods: A prospective, single...

Suction is produced during prey capture by most teleost fishes. Here, we ask two questions about the functional basis of suction feeding. First, is there variation in the kinematic pattern produced by different species while suction feeding? Second, do species termed 'suction specialists' demonstrate similar modifications to their feeding behavior? We used 10 kinematic variables in a principal ...

Suction-feeding fishes exhibit diverse prey-capture strategies that vary in their relative use of suction and predator approach (ram), which is often referred to as the ram-suction continuum. Previous research has found that ram varies more than suction distance among species, such that ram accounts for most differences in prey-capture behaviors. To determine whether these findings hold at broa...

The nurse shark, Ginglymostoma cirratum, is an obligate suction feeder that preys on benthic invertebrates and fish. Its cranial morphology exhibits a suite of structural and functional modifications that facilitate this mode of prey capture. During suction-feeding, subambient pressure is generated by the ventral expansion of the hyoid apparatus and the floor of its buccopharyngeal cavity. As i...

Suction-based end effectors are widely used in industry and are often preferred over parallel-jaw and multifinger grippers due to their ability to lift objects with a single point of contact. This ability simplifies planning, and handcoded heuristics such as targeting planar surfaces are often used to select suction grasps based on point cloud data. In this paper, we propose a compliant suction...

Dear Editors, Suction blister roof grafting, a method of grafting the epidermis, has been used in the treatment of vitiligo and skin ulcers. Despite damage to keratinocytes and cell death during the suction procedure, application of suction blister roof to wounds appears to aid wound healing, possibly because of the production of cytokines such as TGF-α, PDGF, bFGF, VEGF, IL-1 and IL-6 (1). In ...

We review the origins, prominent innovations, and major patterns of diversification in suction feeding by vertebrates. Non-vertebrate chordates and larval lamprey suspension-feed by capturing small particles in pharyngeal mucous. In most of these lineages the gentle flows that transport particles are generated by buccal cilia, although larval lamprey and thaliacean urochordates have independent...
