The primary aim of the present study is to test the effect of alpha-tocopherol supplementation on the progression of carotid atherosclerosis in patients with coronary artery disease
This study is testing the safety and effectiveness of acupuncture in controlling pain related to the removal of partially impacted mandibular third molars. Acupuncture is the Chinese art of healing by inserting needles into the skin. Participants ages 18 - 40 are given an initial x-ray to determine if one lower molar is partially bony impacted. Eligible participants will then undergo standard oral surgery to remove the impacted molar. A local anesthetic will be used prior to surgery. Directly after surgery the participant will be assigned to one of three groups. Participants will not be able to select which group they are assigned. Participants will receive either real or sham (fake) acupuncture as a treatment for post-extraction pain. After the initial acupuncture treatment, participants are required to remain for six hours at the dental site to be monitored. If a participants discomfort is measured as moderate or higher then a second acupuncture treatment will be administered. All participants will be administered questionnaires during the day of surgery. Participants will also be required to complete two diaries during the seven days following surgery. On the seventh day, participants return to have stitches removed and hand in completed diaries.
The purpose of this study is to test how the body's immune system responds to the vaccine ALVAC-HIV vCP1452 and to determine if the vaccine is safe when given alone and with MN rgp120. HIV infection and AIDS have no cure, in spite of recent advances in anti-HIV drugs. Many worldwide populations cannot afford the antiviral treatments for infected people. HIV vaccines offer hope for disease prevention. In this trial, 2 experimental HIV vaccines called ALVAC vCP1452 and MN rgp120 will be given to volunteers in Haiti, Brazil, Peru, and Trinidad and Tobago. The study will determine how volunteers' immune systems respond to the vaccines. (This protocol has been changed by adding new international sites.)
The etiology of immune-mediated diabetes mellitus (IMD) remains unclear. However, previous studies indicate that autoimmunity may be a result of dysfunction of natural killer T cells (NK-T cells). Newly diagnoses patients with IMD have been shown in our laboratory to have significantly lower NK-T cells than normal controls. Other studies have shown that oral administration of lactobacillus can boost NK-T cell activity in children with HIV without side effects. Our objective is to evaluate the effect of lactobacillus administration on NK-T cell activity in patients with IMD
White blood cells can cause liver damage if they inappropriately accumulate in the liver in large numbers. Such an event can occur if an individual's blood is exposed to endotoxin, a substance released from the cell walls of many species of bacteria. The purpose of this study is to isolate neutrophils, an important white blood cell, from the blood of normal volunteers, and put them in tissue culture with isolated liver cells. The experiments will determine how endotoxin can increase the ability of neutrophils to damage liver cells. All studies supported by this grant will be done with isolated cells in tissue culture. This experimental model will reveal possible mechanisms that can in the future be evaluated in human diseases such as bacterial sepsis.
This study will evaluate a safe and useful medication for outpatient detoxification that is as effective as benzodiazepines in the short-term, and more effective in the protracted withdrawal period. Gabapentin (Neurontin) will be compared to a standard benzodiazepine, lorazepam (Ativan), for its effectiveness in treating alcohol withdrawal.
This project is examining the reproductive effects of exposure to certain compounds that are suspected to act on the endocrine system, e.g. they may act like or interfere with hormones such as estrogen. The study is being conducted among Laotian women, as it is suspected that they may have higher exposures to the compounds of interest (pesticides and PCBs) from their homeland and from consumption of fish caught in the San Francisco Bay. Fifty Laotian immigrants were recruited by community workers to collect urine daily during 3 menstrual cycles for measurement of steroid hormones (estrogen and progesterone). Additionally, they provided a blood sample to measure exposure levels, and completed 2 interviews in their native language. These measured levels, as well as the self-reported data on a number of factors including fish consumption, will be examined for possible effects on hormone levels and menstrual function.
The purpose of this study is to measure blood levels of abacavir in children and adolescents over a period of time following a single dose so that a dosage for adolescents can be determined. Little is known about how abacavir is cleared by the body in adolescents. It has been shown that young children require a higher abacavir dose based on weight than adults. Older children, or adolescents, may not require as high a dose. This study may provide information as to whether the children's dose or the adult dose is better for HIV-infected adolescents.
This proposal is a pilot study to describe the variations of blood sugar in pregnant women with various degrees of glucose intolerance, and how they relate to standardized meals. Blood sugar control during pregnancy is important to prevent complications for the newborn. The variation and timing of the blood sugar measurements in gestational diabetics and how this relates to the baby's outcome is controversial. We will use an FDA approved device called Minimed Glucose Continuous Monitor, which is used in clinical practice for certain diabetics. It is very small, similar to a beeper, and is connected to the patient through a small plastic catheter subcutaneously. This measures blood sugar every five minutes for a total of 288 readings a day with minimum discomfort. The hypothesis of this study is that use of the Minimed glucose monitor will provide information about variations of blood sugar in gestational diabetics that is missed by capillary glucose monitors. Our conclusions will allow us to compare blood glucose trends among the groups. After the data is analyzed in this pilot study, we plan to design a bigger study involving more subjects to study the impact of the blood sugar variations in the outcome of the newborn, and to obtain generalizable results for the population in general.
Both ritonavir (RTV) and indinavir (IDV) are approved by the FDA to treat HIV, but IDV has not been approved for use in children and the doses for the combination of the two drugs has not been studied in children. The purpose of this study is to find a combination of RTV and IDV that is safe, well tolerated, and produces drug levels in the blood of children that are comparable to effective drug levels in the blood of adults. The effectiveness of the drug combination in decreasing the amount of virus in the body will also be studied. The children enrolled in this study will have high HIV viral loads despite taking anti-HIV drugs.
