The rapid increase in the number of genetically modified (GM) varieties has led to a demand for high-throughput methods to detect genetically modified organisms (GMOs). We describe a new dynamic array-based high throughput method to simultaneously detect 48 targets in 48 samples on a Fludigm system. The test targets included species-specific genes, common screening elements, most of the Chinese...

Two new 5-oxomilbemycins, 27-aldehyde-5-oxomilbemycin β12 (1) and 2-hydroxymilbemycin K (2), were isolated from a genetically engineered strain Streptomyces bingchenggensis BCJ60. Their structures were determined by comprehensive analyses of its 1 H and 13 C NMR, COSY, HMQC, and HMBC spectroscopic, HRESI-MS mass spectrometric and comparison with data from the literature. Preliminary studies sho...

background: artificial stimulation of mouse oocyte, in the absence of sperm contribution, can induce its parthenogenic activation of oocyte. ultrasound is one of the newest methods for artificial activation of mammal oocytes, and its successful utilization in pig oocyte activation has been recently reported. our objective was to assess the effect of ultrasound on mouse oocyte activation. materi...

background: nasal fracture is a common fracture due to trauma. gold standard method in diagnosis of nasal fracture is clinical examination and radiography is used in legal situation. recently, ultrasound is recommended as a noninvasive and simple method in diagnosis of nasal fracture. this study investigates the role of ultrasound in diagnosis of nasal fracture. methods: 126 cases with suspecte...

PURPOSE Surgical excision is the definitive treatment for localized recurrence of papillary thyroid carcinoma. Reoperation for recurrence, however, is challenging and associated with increased operative times and complication rates. For safe and effective reoperation, ultrasound-guided charcoal tattooing localization can be used. The aim of this study was to investigate the feasibility and safe...

Biosafety of genetically modified organisms (GMOs) and their derivatives is still a major topic in the agenda of government and societies worldwide. The aim of this review is to bring into light that data that supported the decision taken back in 1998 as an exercise to stimulate criticism from the scientific community for upcoming discussions and to avoid emotional and senseless arguments that ...

OBJECTIVE To evaluate in-vivo placental perfusion fraction, estimated by magnetic resonance imaging (MRI), as a marker of placental function. METHODS A study population of 35 pregnant women, of whom 13 had pre-eclampsia (PE), were examined at 22-40 weeks' gestation. Within a 24-h period, each woman underwent an MRI diffusion-weighted sequence (from which we calculated the placental perfusion ...
