The thirty-six-month immunogenicity evaluation of Quadrivalent HPV (Types 6, 11, 16, 18) L1 Virus-Like Particle (VLP) Vaccine in Chinese female subjects aged 9 to 45 years and male subjects aged 9 to 15 years.

Back pain is a common hormonal disorder in men that may affect the phases of male sexual function. The investigators investigated sexual function in male patients with back pain. A total of 54 men with back pain and 27 age matched voluntary healthy men who served as the as control group were evaluated with a detailed medical and sexual history, including a international erectile function index (IEFI) questionnaire and the Beck Depression Inventory. Serum prolactin, dehydroepiandrosterone sulfate, free testosterone, androstenedione, 17alpha-hydroxyprogesterone, estradiol, free thyroxin and thyrotropin were measured. These variables were compared statistically between the 2 groups.

This prospective study will assess thoroughly functional deficits and their significance in the light of rehabilitation in spinal cord injured patients.

The registry study is to obtain the state of the art of the percutaneous coronary intervention state treatment for coronary heart disease in Beijing area of P.R.China in a real world. The data are collected from 48 hospitals in Beijing area using an uploading system through internet.

The investigators have previously shown that a frequency of 15.95-16.00 Hz protects against acute myocardial infarction in rats. In the current study the investigators would like to investigate whether this frequency enables cardiac patients with exercise-induced chest pain to exercise at higher workload and heart rate. Therefore, patients will undergo two exercise stress tests, one test after being exposed to 30 minutes of the above mentioned frequency and another test after being exposed to sham (no frequency is turned ON). The investigators will measure changes in the electrocardiogram (ECG), workload, exercise time, and subjective measure of chest pain (angina).

The important character of acute lung injury (ALI) is alveolar capillary membrane damage caused by different diseases, such as sepsis, trauma and shock. One of the important pathological stages is the varying degrees of interstitial fibrosis and semi-permeable alveolar membrane fibrosis. It has been proved that CXCL12/SDF-1 (stromal cell-derived factor-1) induces fibrocyte migration, and promotes fibrosis progression. Study indicated that inhibition of TLR4 receptor signaling pathway improves fibrosis progression induced by ALI, however, the role of fibrocyte in ALI is still unclear. The fibrocytes was significantly increased in asthmatic patients with pulmonary fibrosis, which companies with increased CTGF expression. Therefore, this project assumes that fibrocyte will differentiation to fibroblast/myofibroblast in patient with acute lung injury, which in turn leads to progression of fibrosis. The central hypothesis of this project is that peripheral progenitor cell fibrocytes play an important role in alveolitis caused by acute lung injury. The overall objective of this project is to study the role of fibrocytes in acute lung injury.

The investigators previously developed approaches to SNP-, CNV- and haplo-type single human cells (Vanneste et al. 2009, Nature Medicine). These methods open the possibility to be developed into a novel generic diagnostic technique which broadens the spectrum of disease-alleles that can be selected against during preimplantation genetic diagnosis (PGD) and which enables to help those couples that cannot be supported by PGD yet. PGD is the genetic analysis of a single blastomere from an in vitro fertilized (IVF) embryo and it is offered to couples to avoid the transmission of heritable genetic disorders to their offspring. PGD analyses are performed for (1) autosomal dominant or recessive monogenic diseases, (2) X-linked disorders and (3) chromosomal aberrations that may result in aneuploid conceptions. This novel method is likely to outperform and hence, replace current techniques for preimplantation genetic diagnosis. In this project the investigators will bring the technology from a proof-of-principle to the clinical application. To this end the investigators will make computational improvements for accurate single blastomere SNP-, CNV- and haplo-typing and perform a large validation study. For the validation studythe investigators will analyse the genomes of the blastomeres derived from 60 spare embryos of different origin: (1) Embryos diagnosed as genetically abnormal using current PCR- and FISH-protocols. (2) Embryos diagnosed as normal for the investigated region using current PCR- and FISH-protocols, but not of sufficient quality to be transferred or frozen. (3) Embryos of the sex that is selected against following PGD based sex-selection, or embryos of the sex that is selected for but of insufficient quality to be transferred or frozen. (4) Embryos that were not biopsied in a PGD cycle since they suffer a slight growth delay. This validation study will allow us to evaluate (1) the clinical validity (false positive and negative rate) and (2) clinical applicability (in terms of ease of use, success rate, etc.). In addition, it will bring us essential further fundamental insights in the origins and mechanisms of chromosomal instability operating during early embryogenesis and its consequences for clinical applications of PGD. Finally, following the validation study, this project will clinically implement the technique to treat 10 families.

The biological basis for insulin resistance associated with obesity is unknown. By studying equally-overweight/obese individuals who are either insulin resistant or insulin sensitive, the investigators will compare characteristics of fat tissue to test several hypotheses: 1) impaired differentiation and fat storage in the subcutaneous fat depot characterize insulin resistant individuals, who have, as a result, fat in other tissues like liver and muscle, as well as more fat circulating in the blood; 2) inflammation is greater in visceral and/or subcutaneous adipose tissue depots in insulin resistant individuals as compared with insulin sensitive individuals.

3,6-bis(1-methyl-4-vinylpyridinium) carbazole diiodide (BMVC) is an inorganic chemical compound (Figure1). The uptake of BMVC in cancer cells and normal cells are different. Recently, a simple handheld device (Figure1) based on the fluorescence analysis of stained cells was established to instantly differentiate cancer cells from normal cells. The investigators want to quantitatively measure the fluorescence expression of BMVC in normal and cancer cells and explore the usefulness of this staining in head and neck lumps.

The purpose of this study is to evaluate the improvement in severity of Atopic Dermatitis and quality of life after 4 weeks of treatment in the Dead Sea.
