We treated 16 patients with acute and chronic acromioclavicular dislocations type III and V by open reduction and fixation using a Hook plate (AO). Plate removal was performed 7 months later on average (range 3 1/2 - 13). A clinical and radiological follow-up was performed after a mean time interval of 29 months (range, 11-40) from the date of plate removal. The L'Insalata scoring system was us...

11 1951, Paul S. Dwyer pnblishcd I,inenr Comptntions, perhaps the first hook dcvoted cntirely to numerical linear algebra.' Digital conipiiting was in its infancy, and Dwyer focused on computation with tncchanical calculators. Nonctheless, the hook was state of the art. Figurc 1 reproduces a pagc of thc book dealing with Gaussian elimination. In 1954, Alston S. Householder published Prim+ p b n...

Effects of the kampo medicine yokukansan on gene expression of the cystine/glutamate antiporter system Xc-, which protects against glutamate-induced cytotoxicity, were examined in Pheochromocytoma cells (PC12 cells). Yokukansan inhibited glutamate-induced PC12 cell death. Similar cytoprotective effects were found in Uncaria hook. Experiments to clarify the active compounds revealed that geissos...

This study describes a new technique called the "fish hook" technique for the treatment of bony mallet finger. This technique catches the dorsal fragment with a bent K-wire shaped like a fish hook. Transarticular fixation is performed with another K-wire. This technique does not directly penetrate the bone fragment to prevent fragment comminution. This study included 26 patients with mallet fin...

UNLABELLED Boden et al. suggested syndesmosis fixation was not necessary in distal pronation external rotation (PER) ankle fractures if rigid bimalleolar fracture fixation is achieved and was not necessary with deltoid ligament injury if the fibular fracture is no higher than 4.5 cm of the tibiotalar joint. We asked whether height of the fibular fracture with or without medial stability predict...

The transformation-associated recombination (TAR) cloning technique allows selective and accurate isolation of chromosomal regions and genes from complex genomes. The technique is based on in vivo recombination between genomic DNA and a linearized vector containing homologous sequences, or hooks, to the gene of interest. The recombination occurs during transformation of yeast spheroplasts that ...

BACKGROUND Hook plates are used to treat acromioclavicular joint dislocations. Our study took into consideration the patients' outcome following treatment with clavicular hook plates retained for more than five months. OBJECTIVES Our aim was to assess the response to treatment of acromioclavicular joint dislocation by clavicular hook plate when retained for more than five months. PATIENTS A...

Mycoplasma mobile binds to solid surfaces and glides smoothly and continuously by a unique mechanism. A huge protein, Gli521 (521 kDa), is involved in the gliding machinery, and it is localized in the cell neck, the base of the membrane protrusion. This protein is thought to have the role of force transmission. In this study, the Gli521 protein was purified from M. mobile cells, and its molecul...

The phenomenon of the etiolated hook is not restricted to the hypocotyl of the dicotyledenous plant (e.g., Phaseolus) but appears to serve a similar, adaptive function in the petioles of certain rhizomatous plants. The commonly employed regulants of hypocotyl hook opening were tested for their effect on the petiolar hook of Dentaria diphylla. The hook was found to require both light (red light ...

The apical hook is an essential structure that enables epigeal plants to protrude through the soil. Arabidopsis thaliana HOOKLESS1 (HLS1) is reported to be a key regulator of hook development and a direct target gene of the ethylene (ET)-activated transcription factors ETHYLENE INSENSITIVE3 (EIN3) and its close homolog EIN3-Like1. Previous research has shown that the phytohormones jasmonate (JA...
