You will be shown inclusion or exclusion criteria for a clinical trial. Given these criteria, your task is to extract all unique entities of the following types: ["Observation", "Condition", "Procedure", "Drug", "Temporal", "Multiplier", "Qualifier", "Negation", "ReferencePoint", "Scope", "Value", "Mood", "Device", "Visit", "Measurement", "Person"].

Please return the output as a JSON object of the format: {"Condition" : ["breast cancer", ...], "Device" : ["ports", ...], "Drug" : ["Atenolol", ...], "Measurement" : ["blood pressure", ...], "Mood" : ["suspected", ...], "Multiplier" : ["more than two", ...], "Negation" : ["no", ...], "Observation" : ["history", ...], "Person" : ["male", ...], "Procedure" : ["surgery", ...], "Qualifier" : ["severe", ...], "ReferencePoint" : ["enrollment", ...], "Scope" : ["infection", ...], "Temporal" : ["one day", ...], "Value" : ["50%", ...], "Visit" : ["ICU", ...]}. The keys should be entity types and values should be lists of extracted entities belonging to the corresponding type. If you cannot find entities belonging to a specific type, the value should be [].

Only output the JSON object and do not include any additional text.

Abstract:

Able to provide voluntary, written informed consent with comprehension of all aspects of the protocol, prior to any study procedures. 
Healthy obese male and female volunteers aged 18 to 55 years, inclusive. Heterozygous subjects may be 18 to 65 years inclusive. 
In good general health, without significant medical history, physical examination findings, or clinical laboratory abnormalities. 
Body Mass Index of 30-40 kg/m2, inclusive. Heterozygous subjects may have a broader BMI range; to be eligible heterozygous subjects may have a BMI 27 -55 kg/ m2, inclusive. 
Stable body weight during the previous 6 months, based on Investigator judgment. 
Blood pressure <140/90 mmHg at Screening and D-1. Measurement may be repeated within 24 hours, based on Investigator judgment. 
Females must not be pregnant and must have a negative serum pregnancy test result at the Screening Visit and Day -1. 
Females of childbearing potential must agree to be abstinent or else use any two of the following medically acceptable forms of contraception from the Screening Period through the Final Study Visit: hormonal, condom with spermicidal jelly, diaphragm or cervical cap with spermicidal jelly, or IUD. Hormonal contraception must have started at least 3 months prior to screening. A female whose male partner has had a vasectomy must agree to use one additional form of medically acceptable contraception. Subjects must agree to practice the above birth control methods for 30 days from the final visit as a safety precaution. 
Females of non-childbearing potential, defined as surgically sterile (status post hysterectomy, bilateral oophorectomy, or bilateral tubal ligation) or post-menopausal for at least 12 months (and confirmed with a screening FSH level in the post-menopausal range), do not require contraception during the study. 
Males with female partners of childbearing potential must agree to use two medically acceptable forms of contraception as described above, with one of the two forms being condom with spermicide, from the Screening Period through the Final Study Visit. Males with female partners of childbearing potential who themselves are surgically sterile (status post vasectomy) must agree to use condoms with spermicide over the same period of time. Male subjects must agree to practice the above birth control methods for 30 days from the final visit as a safety precaution.
