Effects of Steroids

The kind of binding the steroids have to hormones determines the immediate effects of steroids in the brain. Androgen (male sex hormone) and estrogen (female sex hormone) receptors on the surface of a cell attract steroids. The steroid–receptor complex affects the cell nucleus and can influence patterns of gene expression. Because of this, the acute effects of steroids in the brain are substantially different from those of other drugs. Steroids are not euphorigenic, and do not trigger rapid increases in the neurotransmitter dopamine, which is responsible for the high that often drives substance abuse behaviors. However, long term steroid use eventually influences the same brain pathways and affects chemicals such as dopamine, serotonin and opioid systems. Considering the combined effect of their complex direct and indirect actions, it is not surprising that Steroids can affect mood and behavior in significant ways.

Y chromosome

The Y chromosome is the sex-determining chromosome in most mammals, including humans. In mammals, it contains the gene SRY, which triggers testis development, thus determining sex. The human Y chromosome is composed of about 60 million base pairs. Most mammals have one pair of sex chromosomes in each cell (though the platypus has five pairs). Males have one Y chromosome and one X chromosome, while females have two X chromosomes. In mammals, the Y chromosome contains the gene that triggers embryonic development as a male. This gene is SRY. Normal sperm production needs other genes, in addition to SRY, on the Y chromosome.

Melanoma

Melanoma is a malignant tumor of melanocytes, which present in skin but also in the bowel and the eyes. It is one of the more rare types of skin cancer, but causes the majority of skin cancer-related deaths. Malignant melanoma is a serious type of skin cancer. Uncontrolled growth of pigment cells, called melanocytes cause cancer. Despite many years of intensive laboratory and clinical research, the sole effective cure for melanoma is surgical resection of the primary tumor before it achieves a Breslow thickness greater than 1mm. Each year doctors diagnose around 160,000 new cases of melanoma and it presents more frequently in males and Caucasians. It is more common in Caucasian populations living in sunny climates than other groups. According to a WHO report, about 48,000 melanoma-related deaths occur worldwide per annum.

Hollywood

Hollywood is a neighborhood in Los Angeles, California that is situated west-northwest of Downtown Los Angeles. Due to its fame and cultural identity as the historical center of movie studios and movie stars, the word "Hollywood" is a metonym of American cinema, and people often use it interchangeably to refer to the greater Los Angeles area in general. The nicknames Star Struck Town and Tinsel Town refer to Hollywood and its movie industry. In 1853, one adobe hut stood in Nopalera, named for the Mexican Nopal cactus indigenous to the area. By 1870, an agricultural community flourished in the area with thriving crops of many common and exotic varieties. The residents called this area the Cahuenga Valley, after the pass in the Santa Monica Mountains immediately to the north. Soon thereafter, land speculation would lead to subdivision of the large plots and an influx of homeowners. Hollywood incorporated as a municipality on November 14, 1903. The vote was 88 for incorporation and 77 against it. On January 30, 1904, the voters in Hollywood decided, by a vote of 113 to 96, for the banishment of liquor in the city, except when it was for medicinal purposes. Neither hotels nor restaurants served wine or liquor before or after meals. By 1910, because of an ongoing struggle to secure an adequate water supply, town officials voted for Hollywood to annex into the City of Los Angeles for its water system. Los Angeles was a growing city and had opened the Los Angeles Aqueduct that was piping water down from the Owens River in the Owens Valley. Another reason for the vote was that Hollywood could have access to drainage through Los Angeles' sewer system. With annexation, the name of Prospect Avenue changed to Hollywood Boulevard and all the street numbers in the new district changed.
