Nowadays, mostly vegetable fat blends are used in infant formula, but the use of bovine milk fat is increasing. In terms of fat structure, bovine milk fat and vegetable fats differ. Bovine milk fat has a higher percentage of palmitic acid attached to the sn-2 position of the glycerol backbone compared to vegetable fat blend. Also bovine milk fat contains milk fat globular membranes, as opposed to vegetable fat. With this study the investigators want to examine the effects of a vegetable fat blend versus bovine milk fat without globular membranes and bovine milk fat with globular membranes on underlying mechanistic, immune and metabolic responses.
This study is to explore the driving genes and the molecular mechanism of malignant transformation of adenomyosis. This study acquired the formalin fixed paraffin-embedded (FFPE) tissue of patients pathologically conformed endometrial carcinoma arising in adenomyosis (EC-AIA) treated at Peking Union Medical College Hospital from July 15, 2017 to July 15, 2019. The formalin fixed paraffin-embedded tissues from patients pathologically diagnosed with adenomyosis during this time period were also included as control specimens. The eutopic endometrium, normal adenomyosis tissue, and EC-AIA tissue were harvested from the FFPE tissue from patients with EC-AIA. The normal eutopic endometrium and normal adenomyosis tissue were obtained by laser microdissection. The driving genes and potential molecular mechanism of EC-AIA will be found by the technology of whole exome sequencing and transcriptomics (RNA-sequencing).
This study aims to analyze the multi-omics results between eutopic endometrium, adenomyosis and endometriosis of patients diagnosed of adenomyosis with and without endometriosis. The multi-omics profiles include whole exome sequencing, analysis of transcriptomics and metabolomics. A comprehensive multi-omics will reveal the pathogenesis of adenomyosis.
Background: - People with sickle cell disease and other blood disorders sometimes get chronic leg ulcers. These are wounds that develop on the skin and don t go away. Current treatments do not work very well, so researchers want to learn more about why the ulcers happen. They want to find out which bacteria may cause it, and if external factors play a role. Objective: - To study social and environmental factors of sickle cell disease and the causes of sickle cell disease leg ulcers. Eligibility: - People age 18 and older who have sickle cell disease or another red cell disorder, with or without an active leg ulcer. Design: - Participants will have a medical history and clinical evaluation. They will also have blood drawn. - Participants will complete questionnaires about their life, health, environment, stress, and other topics. - Participants may provide a small sample of hair. - Participants will be asked to collect a small amount of saliva. - Participants with leg ulcers will have their skin microbiome sampled. The microbiome is all of the microbes (bacteria and and/or fungi) and their genes in and on the body. Researchers will use swabs to collect skin samples. Photographs will be taken of the skin sample area. - Some participants without leg ulcers also will have their skin microbiome sampled. - Some participants who have their skin microbiome sampled will return for a second visit. At this visit, their microbiome will be resampled. It will take place more than 30 days after the first visit.
