Diagnosis and Therapy of Vulnerable Atherosclerotic Plaque
The aim of the present study is to examine the atherosclerotic plaque stability using in vivo and in vitro techniques and to investigate the influence of exercise, anti-diabetic, lipid-lowering and cannabinoids receptor antagonists on atherosclerotic plaque texture in patients with cardiovascular risk and animals prone to atherosclerosis.

A Glycemic Control Evaluation of Glimepiride Versus Rimonabant on Top of Metformin in Type 2 Diabetes
The primary objective is to demonstrate, after 52 weeks of treatment, the non-inferiority of rimonabant 20 mg once daily (od) versus glimepiride od in reducing glycosylated haemoglobin (HbA1c) in overweight/obese patients with type 2 diabetes not adequately controlled with metformin at a stable dose (≥ 1500 mg/day) for at least 3 months.
The main secondary objectives are to assess the effect of rimonabant in comparison with glimepiride on body weight and HDL-Cholesterol and the long-term safety and tolerability of rimonabant in comparison with glimepiride.

China Cognition and Aging Study
The aim of this study is to establish and perfect the China Cognition and Aging Study (China COAST) cohort, to clarify the epidemiology, influencing factors, genetic characteristics, pathogenesis, disease characteristics and diagnosis and treatment status of dementia and its subtypes in China. It is of great significance to establish a relatively comprehensive national database of cognitive disorders, improve the clinical diagnosis and treatment level of cognitive disorders, and formulate prevention and treatment strategies for dementia. The primary aims of China COAST are as follows:
To use the prospective cohort to establish a large database research platform, so as to provide comprehensive epidemiological data, clinical and neuropsychological evaluation data, biological samples, and laboratory tests and imaging data.
To update the prevalence and incidence rate of dementia and its subtypes every 2-3 years, and clarify the conversion pattern from normal elderly to MCI and from MCI to dementia.
To explore the known or unknown protective and risk factors of dementia and its major subtypes (AD, VaD, other dementia).
To discover new pathogenic genes and susceptible genes of dementia and its major subtypes (AD and VaD), as well as new mutation sites of known pathogenic genes. To study the genetic variation, mutation and polymorphism of PSEN1, PSEN2, APP and APOE genes in dementia patients, and to understand their distribution and roles in the pathogenesis.
To study the biomarkers (body fluid, genetics, imaging) with diagnostic value of MCI, AD (sporadic and familial) and VaD, to define their cut-off values, and to establish prediction models.
To study the diagnostic criteria of cognitive normal, MCI, dementia and their subtypes (clinical and molecular subtypes) in the cohort, and to make psychological assessment scales with high sensitivity and specificity, and in line with the characteristics of Chinese people.
To find potentially modifiable risk factors for dementia and to study the prevention and intervention effect of non-pharmacological treatment on APOE ε4 carriers, MCI and AD or other dementia patients，which included improvements in education, nutrition, health care, and lifestyle changes. This needs a long time follow-up.
To explore the relationship between dementia as well as its major subtype AD and cerebral and systemetic circulatory disorders (for example, mixed dmentia), as well as potential therapeutic strategies.
To carry out investigation and researches about dementia related education, improve the awareness of dementia, and strengthen the management of dementia.

Studies of Skin Microbes in Healthy People and in People With Skin Conditions
This study will examine microbes (e.g., bacteria, fungi, viruses) that live on human skin and how microbes contribute to health and disease. It will analyze healthy human skin and how the these microorganisms might change in patients with atopic dermatitis (AD), a skin condition also known as eczema.
Healthy volunteers, as well as patients with moderate to severe eczema (AD), between 2 and 40 years of age may be eligible for this study.
We also wish to enroll children and adults aged 2-40 who have been diagnosed with inherited immune disorders known as HIES (hyperimmunoglobulin-E syndrome), WAS (Wiskott-Aldrich syndrome), or DOCK8 immunodeficiency because they frequently have skin problems similar to AD.
Eligible participants undergo the following tests and procedures:
Medical family and medication history
Blood tests (research blood as well as serum IgE, and complete blood count)
Skin samples to analyze microbes. Samples are obtained by the following methods: swabbing the skin with a cotton swab; scraping (scratching) the skin gently with a blade to remove only the outermost skin layers; and, only in adults, biopsy (surgical removal) of a small skin sample less than 1/4-inch (5 mm) in diameter.
Nose swabs to analyze microbes.
Patients with eczema may have photographs of their skin taken to help monitor the skin rashes.
Participants may be contacted periodically for follow-up studies. Patients with atopic dermatitis may have additional skin samples collected to examine changes in the skin bacteria over time and during all of the stages of eczema. In addition, patients who have a flare of their eczema are asked to undergo a skin sample collection as soon as possible.

Dyskinesia in Parkinson's Disease (Study P04501)
The purpose of the study is to assess the efficacy and safety of a range of doses of SCH 420814 (preladenant) when used together with a stable dose of L-dopa/dopa decarboxylase inhibitor to treat Parkinson's disease. In this study, we will be comparing 3 doses (1 mg, 2 mg, and 5 mg taken twice a day) of preladenant with placebo (sugar pill). Following an Interim Analysis (temporary hold for new enrollment-ongoing subjects will continue on treatment) to review drug safety, a new dose group of 10 mg (taken twice a day) may be added.
Approximately 160 participants will be randomized in this study in approximately 22 study centers worldwide for the first part of this study. Following the Interim Analysis, 40 new participants may be added, for a total of 200 participants. The study is double blind, which means neither you nor your study doctor will know whether you are receiving the study medication or placebo.
