Technological characteristics of the robotic platform may play a role in decreasing challenges minimally invasive left colectomy for benign or malignant diseases. The literature regarding is scarce and focuses mainly on approach complicated diverticular disease, showing good clinical results. Robotic performed with three instruments (a monopolar hook scissor; bipolar forceps Cadiere forceps) on...

Clinical benign prostatic hyperplasia (BPH) is one of the most common cause of lower urinary tract symptoms and transurethral resection of prostate (TURP) has been the gold standard technique for surgical treatment of benign prostate obstruction (BPO) over the last 2 decades. Although monopolar TURP is considered a safe and effective option for surgical management of BPO, there are some disadva...

Neural stem and progenitor cells giving rise to neurons in developing mammalian neocortex fall into two principal classes with regard to location of mitosis-apical and basal, and into three principal classes in terms of cell polarity during mitosis-bipolar, monopolar, and nonpolar. Insight has been gained into how inheritance of polarized, apical and basal, cell constituents is related to symme...

OBJECTIVE To perform a prospective, randomized, long-term comparison between bipolar plasma vaporization of the prostate (BPVP), bipolar transurethral resection in saline (TURis), and monopolar transurethral resection of the prostate (TURP) concerning the perioperative and follow-up parameters. METHODS A total of 510 patients with benign prostatic hyperplasia (BPH), Q(max) <10 mL/s, Internati...

In retinal neuroprostheses, spatial interaction between electric fields from various electrodes - electric crosstalk - may occur in multielectrode arrays during simultaneous stimulation of the retina. Depending on the electrode design and placement, this crosstalk can either enhance or degrade the functional characteristics of a visual prosthesis. To optimize the device performance, a balance m...

OBJECTIVE This study aims to compare radiofrequency (RF) heat lesion size across electrodes and generator settings available for interventional pain management. METHODS Monopolar lesions are generated ex vivo in animal tissue using sharp cannulae with tip diameters 23, 22, 20, 18, 16 gauge; tip lengths 5, 6, 10, 15 mm; set temperatures 60, 70, 80, 90°C; set times 1, 1.5, 2, 3, 5, 10 minutes. ...

Cell polarity is essential for various cellular functions during both proliferative and developmental stages, and it displays dynamic alterations in response to intracellular and extracellular cues. However, the molecular mechanisms underlying spatiotemporal control of polarity transition are poorly understood. Here, we show that fission yeast Cki3 (a casein kinase 1γ homolog) is a critical reg...

Segregation of homologs at the first meiotic division (MI) is facilitated by crossovers and by a physical constraint imposed on sister kinetochores that facilitates monopolar attachment to the MI spindle. Recombination failure or premature separation of homologs results in univalent chromosomes at MI, and univalents constrained to form monopolar attachments should be inherently unstable and tri...
