CASE REPORT A 55-year-old patient with non-smallcell lung cancer suffered from productive cough due to bronchopulmonary fistula (BPF) following pneumectomy (figure 1A,B). First, we used vascular occlusion coils (Tornado Platin Embolization Coils, Cook, Limerick, Ireland, traditionally used for embolisation of selective vessel supply to arteriovenous malformations) placed endobronchially in conj...

A CMOS widely tunable second-order Gm-C bandpass filter (BPF), intended to be used in multi-sine bioimpedance applications, is presented. The incorporates a transconductor which the responses of two linearized voltage-to-current converters are subtracted. As result, effective transconductance can continuously adjusted over nearly three decades, allows corresponding programmability center freque...

BACKGROUND AND PURPOSE While brain MR imaging is routinely performed, the MR imaging assessment of spinal cord pathology in multiple sclerosis (MS) is less frequent in clinical practice. The purpose of this study was to determine whether measurements of medulla oblongata volume (MOV) on routine brain MR imaging could serve as a biomarker of spinal cord damage and disability in MS. MATERIALS A...

The buccal pad of fat (BPF) is an important structure found in the orofacial region of humans. It is larger in infants and gradually becomes smaller in adults. We present twenty seven (27) cases with an average age of 60 years, with a variety of pathological lesions in which we have used the BPF to reconstruct the defects following resection of tumours. Twenty (74%) patients were diagnosed with...

This study was conducted to evaluate the effects of bio-oil incorporation on properties of bio-oil-phenol formaldehyde (BPF) resol resins along with the optimization of petro-phenol substitution level. Crude bio-oil prepared from endocarp shells of Ziziphus mauritiana by direct solvolytic liquefaction (ethanol-water 1:1 wt./wt. at 300 °C) was used to partially substitute the petro-phenol (30% t...

Objectives: Bronchpleural fistula (BPF) after pneumonectomy is a serious complication, occurring in 1-15% of the cases. Study aim was to evaluate the incidence of BPFs between hand sutured and stapled bronchus closure. Methods: Hospital records of 549 consecutive pneumonectomy patients were reviewed retrospectively. The bronchial stump was closed in 510 patients using a uniform interrupted hand...

Algorithms have been developed for image reconstruction within a region-of-interest (ROI) from fan-beam data less than that required for reconstructing the entire image. However, these algorithms do not admit truncated data. In this work, we investigate exact ROI-image reconstruction from fan-beam data containing truncations by use of the so-called fan-beam backprojection-filtration (BPF) algor...

In this paper one coplanar wide band bandpass filter (BPF) is designed with end-coupled λ/4 open-stub resonator. This coplanar waveguide (CPW) BPF is designed for passband centre frequency 2.5GHz and 100% fractional bandwidth (FBW) at 3dB. The proposed structure exhibits negligible passband insertion loss, sharp transition from passband to stopband, wide attenuation bandwidth, simple fabricatio...

OBJECTIVE To determine whether magnetic resonance imaging (MRI) white matter hyperintensities (WMH), whole-brain atrophy, and cardiovascular risk factors predict the development of cognitive decline and dementia. DESIGN Subjects were recruited into this prospective cohort study and followed for incident cognitive decline for mean (SD) 6.0 (4.1) years. Magnetic resonance imaging dual-echo sequ...
