BACKGROUND Emergency surgical patients account for around half of all NHS surgical workload and 80 % of surgical deaths. Few trainees opt to CCT in General Surgery, and there is no recognised subspecialty training program in Emergency General Surgery (EGS). Despite this lack of training and relevant assessment by examination, there appears to be an increasing number of EGS posts advertised. Thi...
A drift collection calorimeter having a combined radiator and field shaping structure made of lead glass tubing is described. With the aid of the EGS Monte Carlo code we show that such a device, when pressurized to 10 atmospheres, will give a resolution of a/E = 9.6%/E1j2 provided that the shower is contained at a 99% level. Track length restriction and Landau sampling have been included in the...
External guide sequences (EGSs), which are RNA molecules derived from natural tRNAs, bind to a target mRNA and render the mRNA susceptible to hydrolysis by RNase P, a tRNA processing enzyme. Using an in vitro selection procedure, we have previously generated EGS variants that efficiently direct human RNase P to cleave a target mRNA in vitro. In this study, a variant was used to target the overl...
Phenylpropenes, a large group of plant volatile compounds that serve in multiple roles in defense and pollinator attraction, contain a propenyl side chain. Eugenol synthase (EGS) catalyzes the reductive displacement of acetate from the propenyl side chain of the substrate coniferyl acetate to produce the allyl-phenylpropene eugenol. We report here the structure determination of EGS from basil (...
An external guide sequence (EGS) is a RNA sequence which can interact with a target mRNA to form a tertiary structure like a pre-tRNA and recruit intracellular ribonuclease P (RNase P), a tRNA processing enzyme, to degrade target mRNA. Previously, an in vitro selection procedure has been used by us to engineer new EGSs that are more robust in inducing human RNase P to cleave their targeted mRNA...
External guide sequences (EGSs) represent a new class of RNA-based gene-targeting agents, consist of a sequence complementary to a target mRNA, and render the target RNA susceptible to degradation by ribonuclease P (RNase P). In this study, EGSs were constructed to target the mRNA encoding human CC-chemokine receptor 5 (CCR5), one of the primary coreceptors for HIV. An EGS RNA, C1, efficiently ...
Equine grass sickness (EGS) remains a debilitating and frequently fatal neurodegenerative disease of horses. Although the disease was first recognised in the early 1900s, the definitive cause still remains to be elucidated. A peer-reviewed survey by Mellor et al. (2001) ranked EGS as the most important disease of horses within Scotland and northern England, suggesting that research priorities s...
We present a public catalog of galaxy groups constructed from the spectroscopic sample of galaxies in the fourth data release from the DEEP2 Galaxy Redshift Survey, including the Extended Groth Strip (EGS). The catalog contains 1165 groups with two or more members in the EGS over the redshift range 0 < z < 1.5 and 1295 groups at z > 0.6 in the rest of DEEP2. 25% of EGS galaxies and 14% of high-...
رز از مهمترین گیاهان زینتی و معطر دنیا محسوب می شود و به دلیل دارا بودن ترکیبات معطر؛کاربردهای فراوان در صنایع غذایی، داروسازی، آرایشی بهداشتی و عطرسازی دارد. عطر گل رز متشکل از بیش از 500 ترکیب مختلف است که متعلق به سه گروه ترپنوئیدها، فنیل پروپانوئیدها و مشتقات اسید چرب می باشند. مطالعه تفاوت ژن های بیان شده در رز های معطر و غیر معطر منجر به شناسایی چندین ژن کد کننده آنزیم های دخیل در سنتز مو...
Fractures and fracture networks are the principal pathways for migration of water and contaminants in groundwater systems, fluids in enhanced geothermal systems (EGS), oil and gas in petroleum reservoirs, carbon dioxide leakage from geological carbon sequestration, and radioactive and toxic industrial wastes from underground storage repositories. When dealing with EGS fracture networks, there a...
