Conventional prenatal screening tests, such as maternal serum tests and ultrasound scan, have limited resolution and accuracy. We developed an advanced noninvasive prenatal diagnosis method based on massively parallel sequencing. The Noninvasive Fetal Trisomy (NIFTY) test, combines an optimized Student’s t-test with a locally weighted polynomial regression(More)
The applications of massively parallel sequencing technology to fetal cell-free DNA (cff-DNA) have brought new insight to non-invasive prenatal diagnosis. However, most previous research based on maternal plasma sequencing has been restricted to fetal aneuploidies. To detect specific parentally inherited mutations, invasive approaches to obtain fetal DNA(More)
The rising demand for bioethanol, the most common alternative to petroleum-derived fuel used worldwide, has encouraged a feedstock shift to non-food crops to reduce the competition for resources between food and energy production. Sweet sorghum has become one of the most promising non-food energy crops because of its high output and strong adaptive ability.(More)
Angiographically occult cerebrovascular malformation (AOVM) is a type of complex cerebrovascular malformation that is not visible on digital subtraction angiography (DSA). Vascular malformation coexisting with glioma is clinically rare, and glioma coexisting with AOVM is even more rare. To the best of our knowledge, the present study is the first to report(More)
Chronic ossified epidural hematoma is an uncommon complication of ventricular shunt operation, and bilateral chronic ossified epidural hematoma was rare to reported in the literature. We report a 35-year-old man with triventricular hydrocephalus was treated with a ventriculoperitoneal shunt but presenting with chronic epidural hematoma at 3 days(More)
Arteriovenous malformations (AVMs) associated with aneurysm have rarely been reported in the literature. The present study reports the case of a 21-year-old pregnant female patient who presented with a subarachnoid hemorrhage and an intracranial hematoma located in the anterior end of the corpus callosum. Furthermore, an anterior cerebral aneurysm and an(More)
To develop a novel preimplantation genetic screening (PGS) test using next generation sequencing(NGS) as a alternative to current array comparative genomic hybridization (array CGH) method for detection of small segmental translocations in two patients with repeated implantation failure (RIF) and recurrent miscarriage (RM). Inconsistent results were(More)
