A drill system for forming a curved tunnel in a bone includes a drill bit guidance device. The drill bit guidance device includes an elongated stationary outer tube extending along a first axis and an elongated inner tube. The elongated inner tube is configured to slidably move within the elongated stationary outer tube along the first axis and to exit from a distal end of the elongated outer tube. The elongated inner tube has a partially slotted distal end portion including a plurality of semi-cross-sectional slots extending perpendicular to the first axis. Each slot is configured to collapse inward in the slot direction when exiting the distal end of the elongated outer tube, thereby curving the distal end portion of the elongated inner tube.

An apparatus that includes a first read shield and a second read shield and a reader stack between the first and second read shields. The first and second read shields each include a tilted magnetization layer closest to the reader stack to control magnetic field flux lines in a free layer of the reader stack and thereby improve a selectivity of the reader to independently sense and isolate media transitions.

A motor vehicle including a structure including a bottom and which bears a motor powered by a removable power supply battery, the structure further including an element for receiving the battery and an attachment mechanism for attaching the battery onto the receiving element. The receiving element and the attachment mechanism are adapted to enable installation of the battery in the receiving element from the underside of the structure by an upward movement towards the structure, and removal of the battery under the structure by a downward movement in a direction opposite to the structure.

Systems and methods for obtaining target elevation information are disclosed. The systems and methods use multiple vertical transmitters and one or more receivers to infer changes in the elevation plane and the height of objects. Changes in elevation and heights of objects are inferred from path length differences between the transmitters and a particular backscattering point. Using known geometric information regarding the configuration of the transmitters, propagation time differences can be estimated via time delay estimation methods in either the time or frequency domain. Appropriate modulation schemes are used such that the multiple signals transmitted are separable upon reception.

The invention relates to hyaluronic acid nanoparticles for the administration of at least one active ingredient. The inventive nanoparticles comprise hyaluronic acid in salt form a positively-charged polymer, a polyanionic salt and at least one active ingredient. The method of obtaining the aforementioned nanoparticles comprises the following steps consisting in: preparing an aqueous solution of a hyaluronic acid salt, preparing an aqueous solution of a cationic polymer, adding a polyanionic salt to the solution of the hyaluronic acid salt, and stir-mixing said solutions such as to produce the nanoparticles, the active ingredient being dissolved in one of the initial solutions or in the suspension of nanoparticles obtained in order to be absorbed on the nanoparticles. The invention also relates to pharmaceutical and cosmetic compositions comprising the above-mentioned nanoparticles.

The present invention has determined that exogenously added glycosylceramide (GlcCer) and other neutral glycolipids such as the homologous Glc-containing globotriaosylceramide (Gb3Cer), dose-dependently prolonged clotting times of normal plasma in the presence but not absence of APC:protein S, indicating GlcCer or Gb3Cer can enhance protein C pathway anticoagulant activity. In studies using purified proteins, inactivation of factor Va by APC:protein S was enhanced by GlcCer alone and by GlcCer, globotriaosylceramide, lactosylceramide, and galactosylceramide in multicomponent vesicles containing phosphatidylserine and phosphatidylcholine. Thus, the present invention provides neutral glycolipids such as GlcCer and Gb3Cer, as anticoagulant cofactors that contribute to the antithrombotic activity of the protein C pathway. The present invention has also determined that a deficiency of plasma GlcCer is a risk factor for thrombosis. Methods are provided to determine individuals at risk for thrombosis, methods of treatment as well as methods of screening for antithrombotic factors from neutral glycolipids.
