Due to short treatment time, the quality change of food caused by heat can be reduced, high-intensity pulsed electric field (PEF) has been widely used, especially in food industry. PEF system consists of PEF generator, treatment chamber, pump, cooling coil, container and monitoring system. The research status of PEF generator, pulses waveforms, treatment chamber and electrodes were discussed. And the application of PEF on food processing was summarized.

Under ambient pressure, an aqueous solution may not enter the nanopores of a hydrophobic ZSM-5 zeolite, which imposes difficulties to cation-exchange treatment. In the current study, a high-pressure cation-exchange technique is developed. With a relatively short treatment time, the degree of hydrophobicity is significantly increased.

Binderless zeolite macrostructures in the form of ZK-4 microspheres were prepared using anion-exchange resin beads as shape-directing macrotemplates. The particles were synthesized under hydrothermal conditions at different temperatures and treatment times. The influence of the different synthesis parameters was investigated by X-ray diffraction, scanning electron microscopy, fluorescence X, nitrogen adsorption measurements and 29Si solid-state NMR. Fully crystalline spheres similar in size and shape to the original resin beads were obtained by a hydrothermal treatment at the highest temperatures (150–180 °C) for a short treatment time of 24 h. The synthesized microspheres showed to be promising in the molecular decontamination of volatile organic compounds (VOCs).

A case report is presented with Class I malocclusion, moderate lower anterior crowding, maxillary dental midline shift with missing right lateral incisor. The adult orthodontic case was treated comprehensively with the extractions of lower lateral incisor, and upper and lower left first premolars as the balancing extraction. Remarkable improvements were achieved in facial profile, axial anterior inclination, esthetic smile and midline correction in short treatment time. Thus, it is concluded that lower incisor extraction in moderate lower anterior crowding and midline shift yield better and stable results with minimal intervention in select cases.

Stroke is the leading cause of disability and the third cause of death in the United States. About 20% of acute ischemic strokes (AIS) are caused by a large artery occlusion, and restoration of blood flow in a reasonable time is the principle goal of treatment. FDA-approved recombinant tissue plasminogen activator (tPA) administration for treatment of stroke is efficacious, but it has short treatment time window and risk of symptomatic hemorrhage that result in only 3–5% patients of who receive this treatment. Alternatively, endovascular treatment using thrombectomy devices, MERCI and Penumbra systems, has been cleared by the FDA. Without adjunctive therapies, the recanalization rate and clinical outcome associated with these devices could be improved.

Background: Different approaches were proposed in the literature for the treatment of malpositioned ankylosed teeth. The present case report describes a modification of Orthodontic Bone Stretching Technique (OBS) for the repositioning of ankylosed teeth, consisting of dentoalveolar segmental osteotomies performed with piezoelectric instruments followed by orthodontic and orthopedic traction. Case Report: A 22-year-old female in good general health was referred by her orthodontist due to an infraoccluded and ankylosed maxillary upper left canine. Attempts of conventional and corticotomy-assisted orthodontic alignment of the tooth were previously performed with no success. After elevating a full-thickness flap, three osteotomies were performed by using piezoelectric inserts (Piezotome Cube, Acteon, Merignac, France). Mesial and distal cuts were full-thickness osteotomies, parallel to the long axis of the tooth, through the buccal and palatal cortical plates. The apical osseous incision was a horizontal corticotomy, involving only the buccal plate, and connecting the vertical osteotomies two millimetres over the apex of the tooth. Heavy orthodontic forces were immediately applied by using both dental and skeletal anchorage. The initial movement of the dentoalveolar segment was observed three weeks after surgery and case finishing has been completed in two months. At a one-year follow-up, the repositioned canine showed good periodontal conditions, no discoloration and positive pulp response to the electric test. Conclusion: Modified OBS technique was effective in repositioning an infraoccluded and ankylosed maxillary canine, providing satisfactory function and esthetics with short treatment time.

This study evaluated the efficacy of rational-emotive imagery as a component of rational-emotive therapy in reduction of college students' test anxiety. 11 volunteers met for 6 1-hr. group treatment sessions over a 3-wk. period. After 2 initial treatment sessions subjects were randomly assigned to groups given either rational-emotive therapy with rational-emotive imagery or rational-emotive therapy without imagery. Contrary to predictions, improvement between groups on self-report and performance measures was nonsignificant. Failure to obtain differences was attributed to similarities in content of treatment sessions and short treatment time. Combined groups reported significant improvement on all dependent measures. Although the study did not yield the predicted benefits of the imagery, results lend further support to the efficacy of rational-emotive therapy procedures in the reduction of test anxiety.
