Background: The Lori-Bakhtiari sheep breed is one of the most common native breed in the south-western parts of Iran. The peri-parturition period (2 weeks before to, 2 weeks after parturition), is generally of critical importance regarding the health, production and profitability of the ewes. OBJECTIVES: This study was carried out to compare the serum concentrations of glucose, non-esterified f...

cystic fibrosis is an inheritant autosomal recessive disease. it is associated with mutations in cystic fibrosis trans regulator gene (cftr) and has different presentations.we report two 2 month old female patients, products of a twin delivery presented with anemia, edema, hypoalbuminemia and pneumonia.after some work ups, diagnosis of cystic fibrosis was confirmed. this is an uncommon and inte...

The purpose of this study was to determine the effect of twin-to-twin delivery interval on umbilical artery acid-base status of the second twin at birth. This was a retrospective cohort study of all live-born twins with measured acid-base status in umbilical arterial blood who were delivered after 34 weeks' gestation from June 2003 to February 2006. Twins with any maternal or fetal complication...

OBJECTIVE The objective of the study was to determine the incidence, origin, and character of cerebral lesions in monochorionic twins with twin-to-twin transfusion syndrome treated with fetoscopic laser surgery. STUDY DESIGN This was a prospective study of monochorionic twins with twin-to-twin transfusion syndrome treated with fetoscopic laser surgery and monochorionic twins without twin-to-t...

Intermeshing co-rotating twin-screw extruders are very versatile because their screw configurations can be tailored both to the application and properties of materials used. Finding best configuration is one main purposes extrusion modeling, requires models that accurately predict conveying power consumption. The better process predicted, requirements final product met. We present novel predict...

Fetus in fetu is an extremely rare condition embryologically arising in monozygotic diamniotic twins with an incidence of 1:500,000 births. To the best of our knowledge, number of reported cases should not be more than 100 with majority of cases presenting in post natal life with only 5 cases detected prenatally. We are presenting a case diagnosed at 24 weeks of gestation on ultrasound with pre...

We conducted an AX-discrimination task to test for differences in perceived auditory similarity in monozygotic (MZ) and dizygotic (DZ) twin pairs and unrelated speakers. In addition, we performed acoustic analyses to find acoustic correlates that explain the differences in perceived similarity. Results indicate that unrelated speakers are significantly easier to distinguish than twins, but zygo...

A possibility of measuring water vapor column from diffuse irradiance, and thus the extension of optical retrievals to cloudy days, was investigated. The data from the Rotating Shadowband Spectroradiometer (RSS) during its winter deployment at the North Slope of Alaska (NSA) site is used. The initial analysis covers 20 days in March 1999 that include clear, partly cloudy, and overcast days. Dur...

To determine If patients with rest angina have more severe regional Isehemla than padents with exertlonal aiigln., we compared the severity of left coronary artery (LCA) stenods In 29 patIents with transient anterior chemIc S’ -T changes at rest, and 30 patIents with anterior ST changes only during exertion. The percentage diameter stenosis w measured with Vernier calIpers (2 X lesion diameter ...
