Abstract: El mal plegamiento, agregación y acumulación de la proteína Tau en el sistema nervioso es un evento anormal que es responsable de la pérdida sináptica generalizada y la neurodegeneración; puede ocurrir espontáneamente o puede desencadenarse por un plegamiento incorrecto de la proteína β amiloide. La presente invención se refiere al uso del hexapéptido Aβ1-6A2V(D) en el tratamiento de una familia de enfermedades neurodegenerativas relacionadas con la patología tau. En los presentes estudios, se muestra que Aβ1-6A2V(D) es capaz de interferir con la proteína tau en diferentes niveles. Esta propiedad, en asociación con actividades neuroprotectoras adicionales de Aβ1-6A2V(D), ofrece en su conjunto un excelente activo terapéutico contra enfermedades relacionadas con la proteína tau. Además, la administración intranasal de Aβ1-6A2V(D) consigue niveles notables de permeación de este péptido a través de la barrera hematoencefálica, con una amplia distribución del mismo entre las áreas cerebrales más importantes implicadas en la patología tau.

Abstract: The invention relates to an artificial knee-joint 10 with a clamping body 13 which has a journal 11 for securing onto a femoral shaft 12 and which can swing against a brake element situated in the knee-joint housing 14 and there, upon vertical knee-joint loading 44, can bear so as to block the continuation of the swing movement, and a part 36 with a recess 40 for receiving the lower-leg tube of a leg prosthesis, and also a stretching device 36 driving the knee-joint 10 back into the extended position. 
<??>In order to prevent uncontrolled bending of the artificial knee-joint 10, particularly in the event of stumbling, it is proposed to mount rotatably in the knee-joint housing a rotationally-secured roller body connected to the said part 26, and also to mount the clamping body 13 pivotably in such a way that, upon vertical loading of the clamping body 13, the latter swings towards the roller body in such a way that the clamping body 13 and the roller body 19 take up a locking position preventing flexion.

Abstract: A system for subband coding of a digital audio signal x(k) includes in the coder (1) a filter bank (3) for splitting the audio signal band, with sampling rate reduction, into subbands (p = 1, ....P) of approximately critical bandwidth and in the decoder (2) a filter bank (5) for merging these subbands, with sampling rate increase. For each subband (p) the coder (1) comprises a detector (7(p)) for determining a parameter G(p;m) representative of the signal level in a block (p;m) of M samples of the subband signal xp(k) as well as a quantizer (8(p)) for adaptively block quantizing this subband signal in response to parameter G(p;m), and the decoder (2) comprises a dequantizer (9(p)) for adaptively block dequantizing the quantized subband signal sp(k)in response to parameter G(p;m). The quantizing characteristics are related to the noise-masking curve of the human auditory system, owing to which a high-quality of the replica x/< ANd >(k) of audio signal x(k) is attained with an average number of approximately 2.5 bits per sample for representing the output signals of the coder (1). The occasional audibility of quantizing noise in this replica x/< ANd >(k) is reduced effectively in that the coder (1) and decoder (2) contain identical bit allocation means (23, 24) responsive to a set of parameters G(p;m) for the higher group of subbands (pim</=p</=P) within an allocation window (Fig. 5) for allocating a number of B(p;m) bits per sample from a fixed predetermined number of B bits for this allocation window to the quantizer (8(p)) and the dequantizer (9(p)) for the block (p;m) of subband signal xp(k) and sp(k), respectively.

Abstract: In a packaging container (1), for bulk products, made of flexible material in the form of a sack or bag, a removal device having an outlet part for the product is provided for portion-wise removal of product from the filling space. The outlet part forms an outlet path for the product from the filling space to carry out a removal operation via a linear predetermined opening in the packaging material. The opening in the packaging material is predetermined by a material weakening line (15) in one (11) of the package walls. When the material weakening line is separated, a tab of material (18) can be detached at least partially from the packaging material. The outlet part is formed by an inner flexible blank (20) of flat material which is connected to the inside of the packaging wall (11) forming the opening, overlaps the material weakening line (15) substantially and whose upper end part can be pulled out of the packaging wall (11), when the material weakening line (15) has been separated, with formation of a pouring spout. <IMAGE>

Abstract: The system has a specific number (i = 1 to I) of measuring channels, each measuring signal (x<(i)>) having a channel-independent component(s) which is weighted with a channel-dependent compensation coefficient (A<(i)>), and an additive, channel-dependent interfering component (u<(i)>). Initially, a preliminary compensation value (sum) is formed from the measuring signals and the compensation coefficients and preliminary compensated measuring signal values (sk<(i)>) are formed with said compensation value. Measuring channels (j = 1 to J) with a high degree of interference are then sought. For these channels a respective approximation value (ñ) of the interference signal is determined and used to form a correction value (@). A final compensation value (sum'), with which the final compensated measuring signal values (sk') are calculated is formed using the correction values (@).
