Radial motion of the auditory image (approach or withdrawal) was modeled with the help of two loud-speakers placed at different distances from the listener in the anechoic chamber. The thresholds of sound duration for image motion and differential thresholds for its velocity at various azimuthal angles were studied. At azimuthal angles of 0 degrees, 30 degrees, 45 degrees, and 60 degrees, the threshold values of the stimulus durations were 150-200 ms. At an azimuthal angle of 90 degrees from the head midline, it increased by about 25-30% as compared to other angles. In the case of monaural listening to the signals by unilaterally deaf subjects, the threshold durations of the sound signals were two to three times higher as compared to healthy subjects. Differential thresholds for calculated velocity of the radial motion have been measured within the range 0.4-1.0 m/s, increasing with increase of the standard velocity from 3.4 to 6.9 m/s.

Lysosomal storage disorders (LSDs) are rare inherited metabolic disorders characterized by defects in the function of specific enzymes responsible for breaking down substrates within cellular organelles (lysosomes) essential for the processing of macromolecules. Undigested substrate accumulates within lysosomes, leading to cellular dysfunction, tissue damage, and clinical manifestations. Clinical features vary depending on the degree and type of enzyme deficiency, the type and extent of substrate accumulated, and the tissues affected.

Purpose: To investigate the relationship between obstructive sleep apnea hypopnea syndrome (OSAHS) severity and fat, bone, and muscle indices.
Methods: This study included 102 patients with OSAHS and retrospectively reviewed their physical examination data. All patients underwent polysomnography, body composition analysis, dual-energy X-ray absorptiometry, computed tomography (CT) and blood test.

Citrullus lanatus is an important vegetable crop, but it is heavily polluted by cadmium. In this study, we used C. Lanatus as experimental material to investigate effects of different concentrations (0, 50, 100, 200, 400 µmolL) of exogenous melatonin, and grafting on the physiological growth index and anatomical structure of seedlings were studied by simulating Cd (180 mg L) stress environment.

Morphea is a chronic inflammatory fibrosing disorder. Since fibrosis is the hallmark of both scars and morphea, our attention was raised for the possible use of Fractional Ablative CO lasers and microneedling as treatment modalities for morphea. To compare the efficacy and safety of Fractional Ablative CO lasers and microneedling in the treatment of morphea.

Context: "Nanostructure of graphene-reinforced with polymethyl methacrylate" (PMMA-G), and vice versa, is investigated using its molecular structure, in the present work. The PMMA-G nanostructure was constructed by bonding PMMA with graphene nanosheet in a sense to get three different configurations. Each configuration consisted of polymeric structures with three degrees of polymerization (such as monomers, dimers, and trimers polymers, respectively).
