introduction fishing is a leisure activity for some people around the world. accidently the fish hook can get hooked in the hand. if the hook is barbed, removal becomes difficult. we report a case of such a injury in the hand and discuss the technique for its removal with a brief review of the literature. case presentation a thirty-two year old male accidently suffered a fishhook injury to his ...

Hooks of the flagella of Salmonella typhimurium were purified from an flaL mutant. Hook-associated proteins, namely HAP1, HAP2, and HAP3, were separated from them, and the antibody against each HAP was prepared. By immunoelectron microscopic observation, these three kinds of antiHAP antibodies were found to bind on the distal ends of hooks of filamentless mutants consistently with their composi...

Aiming to achieve better results in microlumbar discectomy and foraminotomy, a double-hook retractor has been designed to retract lumbar paraspinal muscles away from the spinous process. A double-hook retractor obviates the limitations of single-hook systems.

Dark-grown dicotyledonous seedlings form a hook-like structure at the top of the hypocotyl, which is controlled by the hormones auxin and ethylene. Hook formation is dependent on an auxin signal gradient, whereas hook exaggeration is part of the triple response provoked by ethylene in dark-grown Arabidopsis seedlings. Several other hormones and light are also known to be involved in hook develo...

The bacterial flagellum is a motile organelle driven by a rotary motor, and its axial portions function as a drive shaft (rod), a universal joint (hook) and a helical propeller (filament). The rod and hook are directly connected to each other, with their subunit proteins FlgG and FlgE having 39% sequence identity, but show distinct mechanical properties; the rod is straight and rigid as a drive...

In [6] Schensted constructed the Schensted algorithm, which gives a bijection between permutations and pairs of standard tableaux of the same shape. Stanton and White [8] gave analog of the Schensted algorithm for rim hook tableaux. In this paper we give a generalization of Stanton and White’s Schensted algorithm for rim hook tableaux. If k is a fixed positive integer, it shows a one-to-one cor...

Abstract. The original motivation for study for hook length polynomials was to find a combinatorial proof for a hook length formula for binary trees given by Postnikov, as well as a proof for a hook length polynomial formula conjectured by Lascoux. In this paper, we define the hook length polynomial for plane forests of a given degree sequence type and show it can be factored into a product of ...

OBJECTIVE Echinococcus granulosus is a globally important cestode parasite causing remarkable medical and economical losses in the world. Ten genotypes (G1-G10) have been identified within this complex species. Protoscoleces rostellar hook characters e.g. total large and small hook lengths may be useful to differentiate genotypes. This study investigates the value of rostellar hook morphometry ...

When penetrating the soil during germination, dicotyledonous plants protect their shoot apical meristem through the formation of an apical hook. Apical hook formation is a dynamic process that can be subdivided into hook formation, maintenance and opening. It has previously been established that these processes require the transport and signaling of the phytohormone auxin, as well as the biosyn...

Early closure of the growth plate after fixing a slipped upper femoral epiphysis is often regarded as favourable since, if growth of the femoral neck continues, the metal may lose its grip on the epiphysis with the possibility of further slipping. However, in the young child early fusion may result in leg length discrepancy and limited motion. The hook-pin (Hansson 1982) permits continued growt...
