BACKGROUND We developed three types of new atrial retractors that facilitate totally endoscopic mitral valve surgery. METHODS Tornado Retractor: This retractor, which is made of rigid thick wire has a unique appearance, and can be inserted atraumatically through a 3-mm skin incision. Butterfly

Nocturnal Hedyloidea butterflies possess ultrasound-sensitive ears that mediate evasive flight maneuvers. Tympanal ear morphology, auditory physiology and behavioural responses to ultrasound are described for Macrosoma heliconiaria, and evidence for hearing is described for eight other hedylid

OBJECTIVE To study the value of choroid plexus dysmorphology as a screening tool for the first-trimester sonographic diagnosis of holoprosencephaly in a high-risk population. METHODS A total of 378 consecutive pregnancies undergoing chorionic villus sampling between 11 and 14 weeks' gestation were

The Massouras Duck's Foot (MDF) IUD and the Butterfly IUD have been clinically evaluated. The MDF, which is Y-shaped, has 2 or 3 horizontal arms on a vertical stem and 2 triangular wings, in between the 'V'. When inserted after curettage, it prevents intrauterine or intracervical adhesions. The

In this paper, we report counter-clockwise, clockwise, and, for the first time to our knowledge, butterfly bistability in 1550 nm Vertical Cavity Semiconductor Optical Amplifiers (VCSOA). Bistable operation is experimentally observed for bias currents ranging from 66-122% of threshold with switching

Though the microscope has helped a lot in otological surgical procedure but it has same optical properties for the last three decades.1 Thus, it has its own limitation as it provides a magnified image along a straight line (Fig 1).2 Meanwhile, the introduction of endoscope in other area of medical

This study reports the design of a novel Butterfly Lamb wave resonator (LWR) employing S0 mode in AlN plate, and for the first time, its ultra-high parallel-resonance quality factor (Qp) of 4,021 is demonstrated, indicating an ultra-low acoustic loss. Although the series resonance quality factor

Fluid accumulations present in the lesser omental bursa and the greater peritoneal cavity simultaneously outline a pattern resembling a butterfly. This "butterfly sign" can contribute to a more accurate diagnosis in evaluation of acute pancreatic processes and, more generally, acute abdominal

OBJECTIVE The aim of this study was to determine whether choroid plexus morphology ('butterfly' sign) and biparietal diameter (BPD) are effective sonographic screening tools for holoprosencephaly (HPE) in the first trimester. METHODS An axial view of the fetal head was obtained routinely to

We develop a mechanistic model for nectar feeding in butterflies that integrates the two basic components of the feeding process: the fluid dynamics of nectar flow through the food canal and the contractile mechanics of the muscular, cibarial pump. We use the model to predict the relation between

Background The endoscopes have better optics and magnification with wide angle of view due to angled lenses. It provides the excellent resolution of image in surgeries having many difficult anatomic nooks and corners like; antero-inferior recess of external auditory canal, middle ear cavity and
