Introduction: Voxel based morphometry is a type of statistical parametric mapping that can be used to investigate the effect of diseases such as epilepsy, Alzheimer's disease and Parkinson's disease or other agent such as skills on brain structure (white matter, gray matter and cerebrospinal fluid). The aim of this study is evaluate the effectiveness of this method in detection of differen...

hottentotta is one of the most widely distributed genera of the family buthidae, with species present throughout africa, the arabian peninsula, and in asia to pakistan and india. recently, kovarik (2007) revised genus of hottentotta in the world and reported 29 different species-group name in the genus of hottentotta. hottentotta is one of the six medical important scorpions of iran that distri...

We report the development of chimeric DNA binding peptides comprising a DNA binding fragment of natural transcription factors (the basic region of a bZIP protein or a monomeric zinc finger module) and an AT-Hook peptide motif. The resulting peptide conjugates display high DNA affinity and excellent sequence selectivity. Furthermore, the AT-Hook motif also favors the cell internalization of the ...

The hook-basal body complex of Salmonella typhimurium, a major component of its flagellar apparatus, was subjected to detailed analysis by electron microscopy and gel electrophoresis. The study was facilitated by the development of an improved protocol for isolation of the complexes in high yield and purity. Nine proteins were identified with the structure. These proteins had apparent molecular...

The Mre11 complex (Mre11, Rad50, and Nbs1) is a central component of the DNA damage response (DDR), governing both double-strand break repair and DDR signaling. Rad50 contains a highly conserved Zn(2+)-dependent homodimerization interface, the Rad50 hook domain. Mutations that inactivate the hook domain produce a null phenotype. In this study, we analyzed mutants with reduced hook domain functi...

In order to explore how the high-dose Hook effect is dependent on the parameters used in our model, we repeated the simulations done for the figure entitled “Reduced hook effect in cooperative (wt) calmodulin” with a range of parameter values. First, we varied all dissociation constants by factors of 10. The results (see figure 1) show that a high-dose Hook effect is observed in all the cases. ...

OBJECTIVE To compare the cost and performance of 2 types of laparoscopic instrumentation: reusable laparoscopic hook cautery instruments and curved scissors, or limited-reuse laparoscopic hook cautery instruments and curved scissors. DESIGN A randomized trial. SETTING The operating room of a tertiary care hospital. METHOD All general surgeons performing laparoscopic procedures at the hosp...

The apical hook of dark-grown dicotyledonous seedlings is a protective structure resulting from an inhibition of cell elongation on the inner portion of the hook. This differential growth response is mediated by ethylene. Expression of the gene encoding 1-aminocyclopropane-1-carboxylate oxidase (ACO), the terminal enzyme in ethylene biosynthesis, is induced by ethylene via a positive feedback l...

BACKGROUND The aim of this study is to investigate the anatomic changes in the shoulder joints responsible for omalgia after the clavicular hook plate fixation under arthroscope. METHODS Arthroscopic examination was carried out for 12 omalgia patients who underwent clavicular hook plate fixation due to distal clavicle fractures. Functional outcome of shoulder was measured by the Japanese Orth...
