  • Steroid hormone receptors are important drug targets and have been the focus of basic and applied research for decades. Steroid hormone receptors act as ligand-dependent transcription factors. Upon ligand binding, the receptors bind to hormone responsive cis-acting DNA elements (HREs) in the nucleus and regulate the expression of target genes by recruiting chromatin-modifying activities that either promote or deny access to the basal transcription machinery.

  • This book brings together core text from the traditional subject areas of oral surgery, oral medicine, oral pathology and radiology to help readers to organise their knowledge in a useful way to solve clinical problems. We believe that this core text of knowledge is essential reading for university final examination success and will also be of help to graduates undertaking vocational training, their trainers and those preparing for postgraduate professional examinations such as MFDS.

  • Hair Follicle Growth and Differentiation Hair can be categorized as either vellus (fine, soft, and not pigmented) or terminal (long, coarse, and pigmented). The number of hair follicles does not change over an individual's lifetime, but the follicle size and type of hair can change in response to numerous factors, particularly androgens. Androgens are necessary for terminal hair and sebaceous gland development and mediate differentiation of pilosebaceous units (PSUs) into either a terminal hair follicle or a sebaceous gland.

  • From the epididymis, sperm move into the vas deferens, the begin- ning of their pathway out of the body. As sperm move through the vas deferens, a number of glands add fluids. Sperm and these added fluids make up the semen. In fact, most of the semen is not sperm. Instead, it consists mostly of fructose, a sugar that provides an additional source of energy for the sperm. Prostaglandins are also found in the semen. Prostaglandins are chemicals that cause muscle contractions to occur in the female reproductive system. These contractions help move the sperm toward the egg.

  • Most cancers found in the adrenal gland did not start there and are not adrenal cancers. Instead, they start in other organs or tissues and then spread (metastasize) through the bloodstream to the adrenal glands. For example, lung cancers, melanomas, and breast cancers often spread to the adrenals. Even when other cancers spread to the adrenals; however, they are still named after the place they started and are treated like other cancers that start in the same place. They are not considered adrenal cancer. Their treatment is described in our documents on these cancers. ...

  • A similar effort may well be in order targeting the gay and bisexual men who are most at risk, particularly those who are living with HIV. Further research is needed to determine the prevalence and incidence of ASIL in the general population of gay and bisexual men outside of major urban centers. Programs are needed to train colposcopists in the skills of identifying and biopsying ASIL; training of colorectal surgeons is needed to optimize identification and treat- ment of ASIL.

  • Two tests are available to screen for prostate cancer: prostate-specific antigen (PSA) and digital rectal examination (DRE). The first of these is a blood test, and the second is a physical examination by a doctor where a finger is passed into the rectum to directly feel for enlargement or a nodule in the prostate gland. The subsequent diagnostic test is a prostatic biopsy taken through the rectum. This paper will discuss the use of PSA as part of a screening program. In clinical practice DRE is used to supplement rather than replace PSA. Wilson and Jungner described a...

  • Pathology The noninvasive proliferation of epithelial cells within ducts is termed prostatic intraepithelial neoplasia. PIN is a precursor of cancer, but not all PIN lesions develop into invasive cancers. Of the cancers identified, 95% are adenocarcinomas; the remainder are squamous or transitional cell tumors or, rarely, carcinosarcomas. Metastases to the prostate are rare, but in some cases colon cancers or transitional cell tumors of the bladder invade the gland by direct extension.

  • Physical Features Patients with AN typically have few physical complaints but may note cold intolerance. Gastrointestinal motility is diminished, leading to reduced gastric emptying and constipation. Some women who develop AN after menarche report that their menses ceased before significant weight loss occurred. Weight and height should be measured to allow calculation of body mass index (BMI; kg/m2). Vital signs may reveal bradycardia, hypotension, and mild hypothermia. Soft, downy hair growth (lanugo) sometimes occurs, and alopecia may be seen.

  • Gonococcal Infections in Females Gonococcal Cervicitis Mucopurulent cervicitis is the most common STI diagnosis in American women and may be caused by N. gonorrhoeae, C. trachomatis, and other organisms. Cervicitis may coexist with candidal or trichomonal vaginitis. N. gonorrhoeae primarily infects the columnar epithelium of the cervical os. Bartholin's glands occasionally become infected. Women infected with N. gonorrhoeae usually develop symptoms. However, the women who either remain asymptomatic or have only minor symptoms may delay in seeking medical attention.

  • With increasing number of cores came the concept of saturation biopsy, a term coined by Stewart et al. (Stewart et al., 2001), in which 20 or more systematic cores were taken. Djavan et al. developed tables to recommend more cores for larger glands, but these met with little clinical acceptance (Djavan et al., 1999). These saturation biopsies have been offered to those who have had previous negative biopsies but continue to have clinical suspicion for prostate cancer.

  • Common household products –detergents, disinfectants, plastics, and pesticides– contain chemical ingredients that enter the body, disrupt hormones and cause adverse developmental, disease, and reproductive problems.
