The new generation of metal-on-metal hip resurfacing is becoming an increasingly popular alternative to total hip replacement in the younger and more active patient. Mid-term survivorship figures for osteoarthritic patients are comparable to that of patients receiving a total hip arthroplasty. However, individuals receiving a hip resurfacing for aetiologies other than OA, such as avascular necr...

Traumatic cleft earlobes are a common problem encountered by plastic and reconstructive surgeons. Various techniques have been reported for the repair of traumatic cleft earlobes. Usually, the techniques of split earlobe repair are divided into two categories, namely straight- and broken-line repairs. Straight-line repair is simple and easy, but scar contracture frequently results in notching o...

This paper presents a feed-forward control scheme for rejecting stochastic narrow band disturbances. The effect of this scheme manifests itself as a tunable notch on the sensitivity transfer function frequency response, where the target frequency, width, and depth of the notch can be set by prescribed design parameters. This approach is based on employing least mean square adaptive control that...

This paper has been focused on the problem of analysis of notching occurring in electric power systems. Especially a choice of appropriate sampling frequency and its consequence for results of the analysis have been considered. Moreover, the problem of wavelet filter length and, in some respect, wavelet family has been analyzed as well. All analyses have been based on the real voltage samples, ...

Adult neural stem cells (NSCs) are perceived as a homogeneous population of cells that divide infrequently and are capable of multi-lineage differentiation. However, recent data revealed that independent stem cell lineages act in parallel to maintain neurogenesis and provide a cellular source for tissue repair. In addition, even within the same lineage, the stem and progenitor cells are strikin...

Introduction Early repolarization pattern (ERP) in the electrocardiogram (ECG) refers to ST-segment elevation above the isoelectric line in the absence of chest pain and/or to terminal QRS slurring or notching in 2 contiguous inferior and/or lateral leads. The underlying electrophysiologic mechanism of ERP remains elusive and is likely heterogeneous. The latter is supported by the fact that alt...

OBJECTIVE To create a library enriched in cDNAs from preeclamptic placentas to print onto microarrays for placental profiling of preeclampsia (PE) and high risk pregnancies. DESIGN Prospective study. SETTING University women's clinic and academic research laboratory. PATIENT(S) Ten patients with PE, 5 with PE and bilateral notching, 5 with bilateral notching without PE, and 15 normotensiv...

We conducted a retrospective study of 36 patients with reverse shoulder prostheses to assess whether placement of the glenoid component affected development of scapular notches. Minimum follow-up was 2 years. Glenosphere position and its relation to scapular notching was analyzed radiographically. The glenosphere overhung the inferior glenoid rim in 19 cases (52.8%) and was flush with the rim i...

The electrocardiogram (ECG) is a commonly available basic diagnostic modality in in-patient, out-patient, and emergency departments. In patients with coronary artery disease (CAD), the presence of a fragmented QRS (f-QRS), which is an extra R wave (R'), notching of the single R wave, notching of the S wave in at least two contiguous leads on the 12-lead ECG, is associated with a myocardial scar...
