This study presents the novel Traction-free Posture orthosis,designed to address wrist stiffness without the use of traditional traction *** orthosis employs a velcro system to stabilize the position of the wrist in flexion or extension,thereby avoiding the compression and rotational disadvantages associated with non-perpendicular traction ***-shaped cuts in the brace allow for plastic material flexibility,ensuring movement and *** is the absence of a traction strap,which traditionally reduces the support surface and could create pressure points leading to patient discomfort or treatment *** design facilitates a wide contact surface with the hand,optimal load distribution,and the capacity to adjust dual traction straps independently,adapting to the natural wrist *** single-piece base orthosis offers a stable,cost-effective,and patientfriendly alternative to conventional ***,patients with stiffness in both flexion and extension may require two separate orthoses,potentially increasing costs and patient ***,the Traction-free Posture orthosis represents an innovative step in wrist rehabilitation,providing a quick-to-construct,easy-to-wear solution with the promise of enhanced patient compliance and comfort.

The research on the collapse of stars, due to Gravity, after the depletion of the fusion fuel, engaged a number of famous guys as Eddington, Chandrasekhar, Schwarzschild and oppenheimer in the years around 1910-1050. During this period, Einstein was writing his field equation of general relativity (1923), fermi, in a famous letter to Pauli, proposed the neutrino in beta decay theory (1930), Chadwick found the neutron, that granted him the Nobel price (1935) and Hubble (1929) proved that the Universe was expanding. As a result of that golden age, we remain with a lot of unsolved questions, due to the poor knowledge of the nature of the strong Nuclear Interaction of Gravity that controls the whole Universe. We have made an investigation on the nature of nuclear bond and gravitational attraction on the basis of available data and as a follow-up of fermi famous research on Neutrino. Using this background, we hope to be able to explain or give some light to the evolution of stars, to the strange objects and phenomena captured or perceived by astronomers in the sky and speculated by theoretical physicists.

Glyphosate-based herbicides are widely used around the world, making it likely that most humans have significant exposure. Because of habitual exposure, there are concerns about toxicity including neurotoxicity that could result in neurological, psychiatric, or cognitive impairment. We recently found that a single injection of glyphosate inhibits long-term potentiation, a cellular model of learning and memory, in rat hippocampal slices dissected 1 day after injection, indicating that glyphosate-based herbicides can alter cognitive function. Glyphosate-based herbicides could adversely affect cognitive function either indirectly and/or directly. Indirectly, glyphosate could affect gut microbiota, and if dysbiosis results in endotoxemia(leaky gut), infiltrated bacterial by-products such as lipopolysaccharides could activate pro-inflammatory cascades. Glyphosate can also directly trigger pro-inflammatory cascades. Indeed, we observed that acute glyphosate exposure inhibits long-term potentiation in rat hippocampal slices. Interestingly, direct inhibition of long-term potentiation by glyphosate appears to be similar to that of lipopolysaccharides. There are several possible measures to control dysbiosis and neuroinflammation caused by glyphosate. Dietary intake of polyphenols, such as quercetin, which overcome the inhibitory effect of glyphosate on long-term potentiation, could be one effective strategy. The aim of this narrative review is to discuss possible mechanisms underlying neurotoxicity following glyphosate exposure as a means to identify potential treatments.

An innovative approach was introduced for the development of a AA6063 recrystallization model. This method incorporated a regression-based technique for the determination of material constants and introduced novel equations for assessing the grain size evolution. Calibration and validation of this methodology involved a combination of experimentally acquired microstructural data from the extrusion of three different AA6063 profiles and results from the simulation using the Qform Extrusion UK finite element code. The outcomes proved the agreement between experimental findings and numerical prediction of the microstructural evolution. The trend of the grain size variation based on different process parameters has been accurately simulated， both after dynamic and static recrystallization， with an error rate of less than 25% in almost the whole sampling computations.

Chitin powder and chitin-aerogel were prepared from shrimp wastes and used to uptake Y^(3+)from aqueous solutions and concentrate this rare earth element from phosphogypsum(PG).Chitin aerogel displays a specific surface area of 945 m^(2)/g,while chitin powder is 3.6 m^(2)/g,which largely influences its adsorption *** the adsorption in synthetic solutions,the effect of pH on Y^(3+)removal is strong for chitin powder *** contrast,no big pH influence was detected for chitin *** interactions and chelation can highlight the proposed mechanism of Y^(3+)on chitin adsorbents for the powder and ***,in addition to these interactions,pore filling/pore diffusion is the main mechanism of Y^(3+)removal in the chitin *** aerogel is efficient in concentrating 8 times the Y^(3+)from PG,a very complex *** complex chitin aerogel-Y^(3+)can be a secondary source of rare earth elements for other applications.
