Amphisbaenians are legless reptiles that differ significantly from other vertebrate lineages. Most species dig underground galleries of similar diameter to that of the animal. We studied the muscle physiology and morphological attributes of digging effort in the Brazilian amphisbaenid Leposternon microcephalum (Squamata; Amphisbaenia), which burrows by compressing soil against the upper wall of...

the use of resistant cultivars remains one of the most reliable methods to manage the pests. in this study the mechanism of resistance in 10 lines of rice for 3 kinds of resistance (antixenoses, antibioses and tolerance) was studied. the egg set of striped stem borer on the leaf of considered lines for antixenoses and larva weight mean and survival percentage of larva were evaluated for antibio...

There is increasing global awareness of adverse reactions to metal debris and elevated serum metal ion concentrations following the use of second generation metal-on-metal total hip arthroplasties. The high incidence of these complications can be largely attributed to corrosion at the head-neck interface. Severe corrosion of the taper is identified most commonly in association with larger diame...

A low head recirculating aquaculture system has been designed, constructed, and is being tested at the Vriginia Tech Aquaculture Lab. Each recirculating system contains two grow-out tanks; a filtration vessel containing a microscreen drum filter; and four rotating biological contactor (RBC) biofilters; sixteen airlift pumps (eight per tank); a regenerative blower with air lines, vacuum lines, a...

Introduction: Knowledge about the different diameters of the head and neck of femur is essential in orthopedic surgery for prosthesis and nail application. The aim of this study was to evaluate the average FNA in the young Egyptians and the effect of age on it. Also, matching sex and side differences of the angle were done by using CT. In addition, the different growth parameters of the proxima...

OBJECTIVE To construct charts offetal biometries at Sukhothai Hospital. MATERIAL AND METHOD One hundred and fifty-one pregnant women attending the antenatal care clinic, Sukhothai Hospital were recruited and received ultrasonographic examinations every four weeks until delivery. RESULTS Biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC), and femur length (FL) w...

With the aim of determining fetal growth kinetics, prenatal data were analysed which had been longitudinally collected in the framework of a perinatal growth survey. The sample comprised 238 singleton normal pregnancies, selected in Genoa and Turin (between 1987 and 1990), and repeatedly assessed by ultrasound scans (five to nine per pregnancy). Five morphometric traits were considered: BPD (bi...

Indications for resection of branch duct intraductal papillary mucinous neoplasms (IPMNs) remain controversial because of their low tendency to be malignant. Surgical resection should be recommended if any factors indicating malignancy are present. However, preoperative differentiation between benign and malignant tumors is very difficult, especially in cases of branch duct IPMNs. We herein rep...
