Objective- To evaluate the clinical safety and superiority of monopolar and bipolar electrocauter in laparoscopic ovariohysterectomy in dogs. Design-Elective experimental study Animals- Twenty four mixed breed healthy adult female dogs. Procedures-The dogs divided into two equal groups. Laparoscopic ovariohysterectomy performed using either monopolar (n=12) or bipolar (n=12) electrocoagulati...

BACKGROUND In certain medical applications, it is necessary to be able to determine the position of a needle inside the body, specifically with regards to identifying certain tissue types. By measuring the electrical impedance of specific tissue types, it is possible to determine the type of tissue the tip of the needle (or probe) is at. MATERIALS AND METHODS Two methods have been investigate...

OBJECTIVE To compare the rate, severity, need for intervention, and blood transfusion requirement in post-tonsillectomy bleeding following the use of either cold dissection or the monopolar microdissection needle method. METHODS A prospective randomized study conducted at Abha Private Hospital, Abha, Kingdom of Saudi Arabia, on patients undergoing tonsillectomy between June 2006 and December ...

Cortex-muscle coherence (CMC) reflects coupling between magnetoencephalography (MEG) and surface electromyography (sEMG), being strongest during isometric contraction but absent, for unknown reasons, in some individuals. We used a novel nonmagnetic high-density sEMG (HD-sEMG) electrode grid (36 mm × 12 mm; 60 electrodes separated by 3 mm) to study effects of sEMG recording site, electrode deriv...

OBJECTIVE To compare the efficacy of intraturbinate monopolar cautery, bipolar cautery, high frequency monopolar and high frequency bipolar cautery in inferior turbinate hypertrophy. STUDY DESIGN Prospective randomized single blinded clinical study METHOD The study comprised of 80 patients divided in 4 groups each of 20 patients who underwent monopolar cautery, Bipolar cautery, high frequen...

BACKGROUND AND OBJECTIVES To determine if surgery using ultrasonic energy for dissection results in less adhesion formation than monopolar electrosurgical energy in the late (8 weeks) postoperative period. METHODS Injuries were induced in rabbits by using ultrasonic energy on one uterine horn and the adjacent pelvic sidewall and using monopolar energy on the opposite side. Eight weeks postope...

OBJECTIVE To compare the histologic appearance of canine skin biopsies collected by use of a scalpel, skin biopsy punch, monopolar electrosurgery, CO2 laser, and radio wave radiosurgery in fully rectified wave form (RWRS). STUDY DESIGN Experimental, randomized design. ANIMALS Healthy adult grayhounds (n=4). METHODS Skin biopsies were collected using 5 techniques. Cut margins of biopsy spe...

Polar and monopolar graphs are natural generalizations of bipartite or split graphs. A graph G = (V,E) is polar if its vertex set admits a partition V = A∪B such thatA induces a complete multipartite and B the complement of a complete multipartite graph. If A is even a stable set then G is called monopolar. Recognizing general polar or monopolar graphs is NP-complete and, as yet, efficient reco...

During cytokinesis, a specialized set of proteins is recruited to the equatorial region between spindle poles by microtubules and actin filaments, enabling furrow assembly and ingression before cell division. We investigate the mechanisms underlying regional specialization of the cytoskeleton in HeLa cells undergoing drug-synchronized monopolar cytokinesis. After forced mitotic exit, the cytosk...
