Proton beam radiation therapy is known to spare surrounding normal tissues from radiation. Proton beam radiation delivers less radiation beyond the area of the target tissues. This may reduce side effects that patients would normally experience with standard (photon) radiation therapy which tends to unavoidably include more normal tissue along with tumor target tissue. In this research study, the investigators are looking to determine if proton beam radiation is effective in controlling your cancer growth. The investigators are also looking to see if proton beam radiation can reduce side effects when compared to standard radiation treatment (photon radiation).

It is unknown whether beta cell dysfunction and insulin resistance in Gestational Diabetes Mellitus (GDM) is representative of a chronic maternal defect, unmasked by pregnancy, or whether it is the result of an imbalance of a placental hormones. Undiscovered placental factors which vary between pregnancies likely contribute to the pathogenesis of GDM. To elucidate the pathophysiology underlying GDM, the investigators will attempt to discover these factors and characterize pregnancy-associated changes in insulin secretion and sensitivity in women with and without GDM.

This study is a Pilot clinical trial. Pilot clinical trials test the safety of an investigational combination of drugs. Pilot studies provide information on what effects, both good and bad, the Investigational agent might have on your disease. "Investigational" means that the intervention is still being studied and that research doctors are trying to find out more about it. It also means that the FDA has not approved the treatment for your type of cancer. The main purposes of this study are to determine: - The amount of vaccine that can be made for your colorectal tumor cells - If the vaccine can be given safely - What the effects of the vaccine are, both good and bad - How the vaccine affects your immune system - Whether this vaccine might have any effect on the return of your cancer in the liver after surgical removal This study is being done because there are currently no treatments which have demonstrated to cure diseae which has progressed, or moved beyond the site of the primary site of disease (colon or rectum). These vaccinations will be given after you have completed the standard of care treatment as determined by your doctor. Laboratory research has made vaccines from cancer cells by inserting genetic material from a protein called granulocyte-macrophage colony stimulating factor (GM-CSF) into the cancer cell. Once complete, the cancer cells are able to produce large amounts of GM-CSF. The vaccine made form these cells has a greater anti-tumor effect than cancer cells without GM-CSF. The purpose of this research study is to determine the safety of an investigational vaccine that will be made using your own colorectal cancer cells in the manner described above. This vaccine has been used in several other research studies for treatment for other cancers (skin, lung, ovarian, sarcoma and leukemia.) Information from these other research studies suggests that this vaccine may help to reduce the risk of your colorectal cancer returning after you have your colorectal cancer surgery. Due to these results in melanoma and several other tumors we are encouraged to use this vaccine approach in patients with liver metastases from colorectal cancer, after the cancer in the liver has been removed by surgery.

The purpose of this study is to explore the effects of synthetic gonadotropin-releasing hormone (GnRH) upon the pituitary and ovaries of women with infertility. Women diagnosed with GnRH deficiency, hypothalamic amenorrhea or acquired hypogonadic hypogonadism, will participate in this study. It is hoped that administration of GnRH will lead to proper stimulation of the pituitary gland and to normal ovulation and menstruation. **WE ARE CURRENTLY RECRUITING ONLY WOMEN WITH A DIAGNOSIS OF IDIOPATHIC HYPOGONADIC HYPOGONADISM (IHH)** Pulsatile GnRH has been approved by the FDA for use in women with primary amenorrhea due to complete GnRH deficiency. The overall goals of this protocol are to continue to use pulsatile GnRH in GnRH-deficient and other anovulatory women for ovulation induction and to examine specific physiologic hypotheses, which can only be addressed in this patient population.

The purpose of this study is to see if repeat bacillus Calmette-Guérin (BCG) vaccinations can confer a beneficial immune and metabolic effect on Type 1 diabetes. Published Phase I data on repeat BCG vaccinations in long term diabetics showed specific death of some of the disease causing bad white blood cells and also showed a short and small pancreas effect of restored insulin secretion. In this Phase II study, the investigators will attempt to vaccinate more frequently to see if these desirable effects can be more sustained. Eligible volunteers will either be vaccinated with BCG in a repeat fashion over a period of four years or receive a placebo treatment. The investigators hypothesize that each BCG vaccination will eliminate more and more of the disease causing white blood cells that could offer relief to the pancreas for increased survival and restoration of insulin secretion from the pancreas.

The main purpose of this study is to examine the outcome of a combined bone marrow and kidney transplant from a partially matched related (haploidentical or "haplo") donor. This is a pilot study, you are being asked to participate because you have a blood disorder and kidney disease. The aim of the combined transplant is to treat both your underlying blood disorder and kidney disease. We expect to have about 10 people participate in this study. Additionally, because the same person who is donating the kidney will also be donating the bone marrow, there may be a smaller chance of kidney rejection and less need for long-term use of anti-rejection drugs. Traditionally, very strong cancer treatment drugs (chemotherapy) and radiation are used to prepare a subject's body for bone marrow transplant. This is associated with a high risk for serious complications, even in subjects without kidney disease. This therapy can be toxic to the liver, lungs, mucous membranes, and intestines. Additionally, it is believed that standard therapy may be associated with a higher risk of a complication called graft versus host disease (GVHD) where the new donor cells attack the recipient's normal body. Recently, less intense chemotherapy and radiation regimens have been employed (these are called reduced intensity regimens) which cause less injury and GVHD to patients, and thus, have allowed older and less healthy patients to undergo bone marrow transplant. In this study, a reduced intensity regimen of chemotherapy and radiation will be used with the intent of producing fewer toxicities than standard therapy. Typical therapy following a standard kidney transplant includes multiple lifelong medications that aim to prevent the recipient's body from attacking or rejecting the donated kidney. These are called immunosuppressant drugs and they work by "quieting" the recipient's immune system to allow the donated kidney to function properly. One goal in our study is to decrease the duration you will need to be on immunosuppressant drugs following your kidney transplant as the bone marrow transplant will provide you with the donor's immune system which should not attack the donor kidney.

The purpose of the study is to explore the way in which gonadotropins (pituitary hormones) are released into the body. The knowledge acquired in this study will be used for the diagnosis and treatment of reproductive endocrine disorders. We seek to investigate the baseline characteristics of the GnRH-induced gonadotropin pulsations of patients with the following diagnoses: - Hypothalamic Amenorrhea (HA) - Idiopathic hypogonadotropic hypogonadism (IHH) - Polycystic ovarian disease (PCOD) - Acquired hypogonadotropic hypogonadism (AHH) - Premature Ovarian Failure (POF) **WE ARE CURRENTLY RECRUITING ONLY SUBJECTS WITH A DIAGNOSIS OF IHH.** This has been an extremely productive and pivotal protocol in the studies of female reproductive physiology and pathophysiology and continues to be critical for defining the neuroendocrine abnormalities in patients with reproductive disorders. In some cases, it is also helpful in the planning of subsequent therapy if so desired. It is important to note that minors have been included in this protocol, as many patients are extremely anxious to know more about their neuroendocrine disorder. With minors who would like to know if their disorder is correctable, this protocol may be followed up with administration of pulsatile gonadotropin-releasing hormone (GnRH).
