The locomotory behaviour of ciliated protozoa results from the activity of the cell's cilia. The major variables in the protozoan's ciliary activity are the orientation of the effective stroke and the beating frequency. Ciliary orientation as used here is the direction of ciliary beat, or more specifically, the direction of the effective or power stroke. The effective stroke is defined as that ...

surgery and MVS. We concluded that the beating heart method was a safe alternative to conventional surgery in redo operations in high-risk groups in particular w15x. Re-operation via the right thoracotomy has become popular because of the difficulties stated above concerning re-operations. We preferred thoracotomy in patients requiring re-operative sternotomy as the right anterolateral thora-co...

Background Autoantibodies against the 81-adrenoceptor have been detected in the sera of patients with idiopathic dilated cardiomyopathy (DCM). The mechanisms by which these autoantibodies can alter normal receptor function are investigated, and the results are interpreted in the light of the beneficial effects of P1-blockade in some of these patients. Methods and Results Autoantibodies against ...

The current work describes an anthropomorphic beating heart phantom constructed as a tool for the assessment of technological advances in cardiac x-ray computed tomography (CT). The phantom is comprised of a thorax, a compressor system, an ECG system, a beating heart with tortuous coronary arteries, and the option to add or remove pathologies such as aberrant beats, stents, and plaques. Initial...

Introduction: Kaposi sarcoma (KS) is an HIV associated skin lesion. Kaposi sarcoma is rare in HIV negative patients and is associated with HHV-8 infection. Clinically it presents as a pink nodular mass, single or multiple which can mimic pyogenic granuloma and bacillary angiomatosis. The etiology associated with HHV-8. Treatment options modalities can vary between from electrocuatery to surgica...

A non-destructive method of collecting cultured cells after identifying their in situ functional characteristics is proposed. In this method, cells are cultivated on an alginate layer in a culture dish and released by spot application of a calcium chelate buffer that locally melts the alginate layer and enables the collection of cultured cells at the single-cell level. Primary hippocampal neuro...

Mitral valve reoperation, through a median sternotomy, for a patient with patent coronary bypass grafts is technically challenging and carries higher postoperative morbidity and mortality than a primary operation. We present a case of mitral valve repair using a beating heart technique under normothermic cardiopulmonary bypass that was performed 3 years after a coronary artery bypass operation....

Coordinated beating of cilia in the trachea generates a directional flow of mucus required to clear the airways. Each cilium originates from a barrel-shaped basal body, from the side of which protrudes a structure known as the basal foot. We generated mice in which exons 6 and 7 of Odf2, encoding a basal body and centrosome-associated protein Odf2/cenexin, are disrupted. Although Odf2(ΔEx6,7/ΔE...

Minimally invasive surgeries (MIS) have been perpetually evolving due to their potential high impact on improving patient management and overall cost effectiveness. Currently, MIS are further strengthened by the incorporation of magnetic resonance imaging (MRI) for amended visualization and high precision. Motivated by the fact that real-time MRI is emerging as a feasible modality especially fo...

We analyze the beating between intrinsic frequencies that are simultaneously generated by a modulation (Turing) instability in a nonlinear extended system. The model studied is that of a coherently driven photonic crystal fiber cavity. Beating in the form of a slow modulation of fast intensity oscillations is found to be stable for a wide range of parameters. We find that such beating can also ...
