STANDARDS There is insufficient evidence to support treatment standards. GUIDELINES There is insufficient evidence to support treatment guidelines. OPTIONS Treatment of atlas-axis combination fractures based primarily on the specific characteristics of the axis fracture is recommended. External immobilization of most C1--C2 combination fractures is recommended. C1--Type II odontoid combinat...

A snake (of length L) is a (continuous) piecewise C1-curve S : [0, L] → R, parameterized by arc-length and whose “tail” is at the origin (S(0) = 0). Charming a snake consists in having it move in such a way that its “snout” S(L) follows a chosen C1-curve γ(t). The snake charmer algorithm, initiated in [Ha2] for polygonal snakes and developed in [Ro] in the general case, works as follows. The in...

To determine whether corneal input is processed similarly at rostral and caudal levels of the spinal trigeminal nucleus, the response properties of second-order neurons at the transition between trigeminal subnucleus interpolaris and subnucleus caudalis (Vi/Vc) and at the transition between subnucleus caudalis and the cervical spinal cord (Vc/C1) were compared. Extracellular single units were r...

UNLABELLED A benzene-poly-carboxylic acid complex with cis-diammineplatinum(II) dihydrocholride, BP-C1 is currently used in clinical trials in treating metastatic breast cancer. BP-C1 controls tumor growth with a few mild side-effects, improving quality of life. METHODS The data consisted of prospectively collected laboratory results from 47 patients in two controlled clinical trials of daily...

Here we describe the phenomenon of symmetry breaking within a series of M4L6 container molecules. These containers were synthesized using planar rigid bis-bidentate ligands based on 2,6-substituted naphthalene, anthracene, or anthraquinone spacers and Fe(II) ions. The planarity of the ligand spacer favors a stereochemical configuration in which each cage contains two metal centers of opposite h...

STUDY DESIGN A retrospective comparative study. OBJECTIVE The aim of this study was to compare the outcomes of anterior screw fixation and posterior temporary-fixation in the treatment of Anderson-D'Alonzo type II odontoid fractures. SUMMARY OF BACKGROUND DATA Posterior C1-C2 temporary-fixation can spare the motion of C1-C2 in the treatment of odontoid fractures. However, it is unknown whet...

Soil organic carbon (SOC) plays a crucial role in controlling the nitrate-dependent Fe(II) oxidation (NDFO) process, especially for saline-alkaline soils. The effects of straw returning combined with Nitrogen (N) fertilizer application on soil NO3−-N content, form and nirK genes were studied five-year field experiment to explore regulatory mechanism SOC NDFO process. Six treatments designed two...

Background Hereditary angioedema (HAE) types I and II (due to quantitative and qualitative C1-INH deficiency, respectively) is a rare autosomal dominant condition in which more than 300 different mutations in the entire C1-INH gene (SERPING1) have been described. The objective of this study is to identify and characterize the mutation in the SERPING1 gene in a family of HAE outpatients from the...

(L1) C causes E iff C stands in the ancestral of influence to E. (L2) C influences E iff (i) C and E are actual distinct events and (ii) there is a substantial range of C1, C2, ... of different not-toodistant alterations of C and a range E1, E2, of alterations of E, at least some of which differ, such that if C1 had occurred, E1 would have occurred, if C2 had occurred, E2 would have occurred an...
