Abstract: The disclosure relates to methods, compositions, and kits for the early determination of the sex of a fetus. The disclosure also provides methods, compositions, and kits for detecting fetal nucleic acids in biological samples (e.g., cell-free fetal DNA).

Abstract: The disclosure relates to methods, compositions, and kits for the preservation of nucleic acids. The disclosure also provides methods, compositions, and kits for preserving nucleic acids in biological samples (e.g., cell-free DNA in blood or saliva).

Abstract: The disclosure relates to methods, compositions, and kits for the early determination of the sex of a fetus. The disclosure also provides methods, compositions, and kits for detecting fetal nucleic acids in biological samples (e.g., cell-free fetal DNA). An embodiment includes a method of improving the accuracy of fetal sex determination by reducing a level of contaminating DNA in a blood sample from a pregnant human subject, comprising obtaining a capillary blood sample collected from the upper arm using a push-button blood collection device, thereby reducing a level of contaminating DNA from a non-maternal and non-fetal source in the capillary blood sample as compared to a blood sample collected from a site on the finger or hand of the subject, and detecting the presence or absence of fetal Y-chromosome to determine the sex of the fetus.

Abstract: The present disclosure provides methods, compositions, and devices for the rapid and direct detection of the sex of a fetus. The disclosure also provides methods, compositions, and devices for detecting fetal nucleic acids in biological samples (e.g., blood, cervical mucus, or urine).

Abstract: A guard structure of a patient support, such as a hospital bed, is electrically unlockable. An electromechanical actuator, such as a solenoid, may be used to electrically unlock the guard structure. The guard structure may also be mechanically unlockable. The guard structure may automatically unlock during a CPR emergency. A maximum allowable height of the patient support may be adjusted based on a sensed locked state or position of the guard structure. A release for the guard structure may be positioned to be accessible to an occupant of the patient support. The release may include an access port that may be opened. The release may include a button that electrically unlocks the guard structure.
