Internet radio and broadcast method

Abstract: Using a large database (160), users may indicate their general or specific preferences with regards to song, artist, or albums. A playlist is created that combines all of the user's preferences as well as any applicable statuatory regulations. The user is then able to enjoy music generally of his or her choosing, while additionally being exposed to new music. Every individual then is like the manager of his or her own radio station.

Flavonoid analyses and antimicrobial activity of various parts of Phaleria macrocarpa (Scheff.) Boerl fruit.

Abstract: Phaleria macrocarpa (Scheff.) Boerl (Thymelaceae) is commonly known as ‘Crown of God’, ‘Mahkota Dewa’, and ‘Pau’. It originates from Papua Island, Indonesia and it grows in tropical areas. Empirically, it is potent in treating the hypertensive,diabetic, cancer and diuretic patients. It has a long history of ethnopharmacological usage, and the lack of information about its biological activities led us to investigate the possible biological activities by characterisation of flavonoids and antimicrobial activity of various part of P. macrocarpa against pathogenic bacteria and fungi. The results showed that kaempferol, myricetin, naringin, and rutin were the major flavonoids present in the pericarp while naringin and quercetin were found in the mesocarp and seed. Furthermore, the antibacterial activity of different parts of P. macrocarpa fruit showed a weak ability to moderate antibacterial activity against pathogenic tested bacteria (inhibition range: 0.93–2.17 cm) at concentration of 0.3 mg/disc. The anti fungi activity was only found in seed extract against Aspergillus niger (1.87 cm) at concentration of 0.3 mg/well. From the results obtained, P. macrocarpa fruit could be considered as a natural antimicrobial source due to the presence of flavonoid compounds.

Management of Bone Loss Associated With Recurrent Anterior Glenohumeral Instability

Abstract: The diagnosis and treatment of osseous deficiencies associated with anterior shoulder instability have been a challenge to physicians for centuries. Whereas historical goals centered on the stable reduction and prevention of recurrent dislocation, current standards of success are predicated on the restoration of motion and strength and the return to functional activities, including competitive athletics. Reestablishment of anterior shoulder stability thus requires the recognition of osseous defects of the humeral head and glenoid, as well as a thorough understanding of the available treatment options in the context of a disciplined treatment algorithm. Although many surgical procedures have been described for the management of osseous deficiencies in association with anterior shoulder instability, in the authors' experience, such procedures are seldom necessary. The purpose of this summary is to review treatment options as well as indications and techniques to address these bony deficiencies.

Vitamin C and vitamin E protect the rat testes from cadmium-induced reactive oxygen species.

Abstract: Cadmium is an environmental and industrial pollutant that affects the male reproductive system of humans and animals However, the mechanism of its adverse effect on Leydig cell steroidogenesis remains unknown The present study points to the possible involvement of oxidative stress in the suppression of steroidogenesis Cadmium administration caused an increase in reactive oxygen species (ROS) by elevating testicular malondialdehyde (MDA) and decreasing the activities of testicular antioxidant enzymes such as glutathione peroxidase and superoxide dismutase The mRNA of Steroid Acute Regulatory (StAR) protein was substantially reduced The activities of testicular delta5-3beta and 17-beta-hydroxysteroid dehydrogenases (HSD) as well as serum testosterone level were also lowered, suggesting that cadmium-induced ROS inhibit testicular steroidogenesis Supplementation with vitamin C (VC) and or vitamin E (VE) reduced testicular ROS and restored normal testicular function in Cd-exposed rats We conclude that VC and VE prevent oxidative stress and play vital roles in co-regulating StAR gene expression and steroid production in cadmium-exposed rats
