Nonlinear beamforming for intracardiac echocardiography: a comparative study.

Unlabelled: Intracardiac echocardiography (ICE) enables cardiac imaging with a wide field of view, deep imaging depth, and high frame rate during surgery. However, strong sidelobe and grating lobe artifacts created by the ultra-compact transducer degrade its image quality, making diagnosis and monitoring of treatment difficult. Conventionally, aperture apodization algorithms are often used to suppress sidelobe and grating lobe artifacts at the expense of lateral resolution, which is undesirable in ICE.

Detection of micro inclusions in steel sheets using high-frequency ultrasound speckle analysis.

With the increasing need for steel sheet quality assurance, the detection of micro-scaled inclusions in steel sheets has become critical. Many techniques have been explored to detect inclusions, e.g.

Real-time delay-multiply-and-sum beamforming with coherence factor for clinical photoacoustic imaging of humans.

In the clinical photoacoustic (PA) imaging, ultrasound (US) array transducers are typically used to provide B-mode images in real-time. To form a B-mode image, delay-and-sum (DAS) beamforming algorithm is the most commonly used algorithm because of its ease of implementation. However, this algorithm suffers from low image resolution and low contrast drawbacks.

Real-Time Photoacoustic Thermometry Combined With Clinical Ultrasound Imaging and High-Intensity Focused Ultrasound.

High-intensity focused ultrasound (HIFU) treatment is a promising non-invasive method for killing or destroying the diseased tissues by locally delivering thermal and mechanical energy without damaging surrounding normal tissues. In HIFU, measuring the temperature at the site of delivery is important for improving therapeutic efficacy, controlling safety, and appropriately planning a treatment. Several researchers have proposed photoacoustic thermometry for monitoring HIFU treatment, but they had many limitations, including the inability to image while the HIFU is on, inability to provide two-dimensional monitoring, and the inability to be used clinically.

Successful treatment of type I endoleak of common iliac artery with balloon expandable stent (Palmaz XL stent) during endovascular aneurysm repair.

Type 1 endoleak of common iliac artery (type I(b) endoleak) should be treated during endovascular aneurysm repair (EVAR). An 86-year-old female was diagnosed with abdominal aortic aneurysm measuring 6.6 cm in diameter and right internal iliac artery aneurysm measuring 4.

Combination treatment with intrahepatic arterial infusion and intratumoral injection chemotherapy in patients with far-advanced hepatocellular carcinoma and arterioportal or arteriovenous shunts: preliminary results.

Background/aims: Combination treatment consisting of hepatic arterial infusion chemotherapy with epirubicin and cisplatin (HAIC-EC) and systemic infusion of low-dose 5-fluorouracil (5-FU) are sometimes effective against advanced hepatocellular carcinoma (HCC). However, there is no effective treatment for advanced HCCs with arterioportal shunts (APS) or arteriovenous shunts (AVS).

Methods: We investigated a response and adverse events of a new combination protocol of repeated HAIC-EC and percutaneous intratumoral injection chemotherapy with a mixture of recombinant interferon-gamma (IFN-γ) and 5-FU (PIC-IF) in patients with far-advanced HCCs with large APSs or AVSs.

[A case of acute phlegmonous gastritis causing gastroparesis and cured with medical treatment alone].

Acute phlegmonous gastritis is an uncommon disease, often fatal condition characterized by suppurative bacterial infection of the gastric wall. It has a high mortality rate mainly because the diagnosis is usually made late. Until recently, gastrectomy in combination with antibiotics was recommended.

Antibiotic resistance profiles of Staphylococcus pseudintermedius isolates from canine patients in Korea.

In this study, the prevalence of antibiotic resistance was examined among 74 Staphylococcus pseudintermedius strains recently isolated from clinical cases of canine pyoderma and otitis externa at the veterinary teaching hospital at Konkuk University, Korea. Bacterial resistance to the nine commonly used antibiotics was evaluated by a standard disk diffusion technique based on the guidelines of the Clinical and Laboratory Standards Institute. The results demonstrated that most S.

Auto-excision of selectable marker genes from transgenic tobacco via a stress inducible FLP/FRT site-specific recombination system.

Antibiotic resistance marker genes are powerful selection tools for use in plant transformation processes. However, once transformation is accomplished, the presence of these resistance genes is no longer necessary and can even be undesirable. We herein describe the successful excision of antibiotic resistance genes from transgenic plants via the use of an oxidative stress-inducible FLP gene.

The comparison of VATS ramicotomy and VATS sympathicotomy for treating essential hyperhidrosis.

This study was undertaken to determine if better results could be achieved by comparing the results of a thoracic sympathetic ramicotomy (division of rami communicantes) with a conventional thoracic sympathicotomy (division of sympathetic trunk) for treating essential hyperhidrosis. From August 2001 to February 2002, 29 consecutive patients underwent surgery of the sympathetic nerves in order to treat severe essential hyperhidrosis. Of these patients, a ramicotomy was performed under VATS (VATS-R) in 13 patients, sympathicotomy under VATS (VATS-S) in 13, a unilateral ramicotomy and contralateral sympathicotomy under VATS (VATS-RS) in 2 and a sympathicotomy via a thoracotomy (T-S) in 1.
