In the heat of a relentless summer, Ned Racine, an inept South Florida lawyer, meets and begins an affair with Matty Walker. Matty's wealthy husband, Edmund, is always away on business during the week. Late one night, Ned arrives at the Walker mansion and, seeing Matty in the gazebo, playfully propositions her. The woman is actually Mary Ann Simpson, Matty's old high school friend who physically resembles her and who is briefly in town. Soon after, Matty tells Ned she wants a divorce, but a prenuptial agreement would leave her almost nothing. When she wishes Edmund was dead, Ned suggests murdering him so Matty can inherit his wealth. Ned consults a shady former client, Teddy Lewis, an explosives expert, who provides Ned a small incendiary device though he advises Ned to abandon his plans.
After murdering Edmund, Ned and Matty move his body to an abandoned building that Edmund owns. Ned detonates the bomb to make it appear as if Edmund accidentally died during a botched arson attempt. Soon after, Edmund's lawyer contacts Ned about a new will that Ned supposedly drafted for Edmund and which was witnessed by Mary Ann Simpson. The new will was improperly prepared, making it null and void and results in Matty inheriting Edmund's entire fortune, while disinheriting his sister. Despite Ned's previous warning against making any estate changes, Matty had forged the new will, exploiting Ned's past malpractice issues, knowing it would be nullified and leaving her the sole beneficiary. Ned knows the police will consider the new will suspicious. A prominent plot point centers on a complicated and often misunderstood legal rule known as the rule against perpetuities.
Matty calls Ned and says that Edmund's glasses are in her boathouse. Ned arrives late that night and spots a wire attached to the boathouse door. Matty arrives, and, following a confrontation, Ned asks her to retrieve the glasses. Meanwhile, Oscar Grace arrives and observes their interaction. To prove herself, Matty walks toward the boathouse and disappears from view; the boathouse then explodes. A body found inside is identified as Matty Walker (née Tyler). Now in prison, Ned, having realized Matty duped him, tries to convince Oscar Grace that she is still alive. He believes that "Matty" assumed the real Matty Tyler's identity in order to marry and murder Edmund. Ned surmises the "Mary Ann Simpson" that Ned previously met had discovered the scheme and was blackmailing Matty, only to be murdered and her body used to identify her as Edmund's wife. Had Ned been killed in the boathouse explosion as Matty likely intended, he reasons the police would have found both suspects' bodies.
In their experiment, the researchers knocked out the mosquito gene responsible for producing the IR21a receptor. They then placed about 60 of the mutant insects into a shoebox-sized container with a plate on its back wall heated to near core body temperature, 98.6 degrees, and gave the mosquitoes a puff of carbon dioxide to mimic human breath.
While non-mutant mosquitoes rapidly congregated on the body temperature plate, trying to feed, the mutant mosquitoes largely ignored the plate. Without the IR21a receptor, they could no longer direct themselves to the hottest spot in their vicinity.
In a second experiment, the mosquitoes were placed in a small mesh cage. Above the cage, the researchers placed two vials full of human blood, with one heated to 73 degrees (room temperature) and the other to 88 degrees (the surface temperature of a human hand). Compared to non-mutant mosquitoes run through the same setup, the mutants showed a reduced preference for the 88-degree blood.
Hypothermia is a medical emergency that occurs when your body loses heat faster than it can produce heat, causing a dangerously low body temperature. Normal body temperature is around 98.6 F (37 C). Hypothermia (hi-poe-THUR-me-uh) occurs as your body temperature falls below 95 F (35 C).
When your body temperature drops, your heart, nervous system and other organs can't work normally. Left untreated, hypothermia can lead to complete failure of your heart and respiratory system and eventually to death.
Hypothermia occurs when your body loses heat faster than it produces it. The most common causes of hypothermia are exposure to cold-weather conditions or cold water. But prolonged exposure to any environment colder than your body can lead to hypothermia if you aren't dressed appropriately or can't control the conditions.
Alcohol and drug use. Alcohol may make your body feel warm inside, but it causes your blood vessels to expand, resulting in more rapid heat loss from the surface of your skin. The body's natural shivering response is diminished in people who've been drinking alcohol.
Water doesn't have to be extremely cold to cause hypothermia. Any water that's colder than normal body temperature causes heat loss. The following tips may increase your survival time in cold water if you accidentally fall in:
The development of isothermal amplification platforms for nucleic acid detection has the potential to increase access to molecular diagnostics in low resource settings; however, simple, low-cost methods for heating samples are required to perform reactions. In this study, we demonstrated that human body heat may be harnessed to incubate recombinase polymerase amplification (RPA) reactions for isothermal amplification of HIV-1 DNA. After measuring the temperature of mock reactions at 4 body locations, the axilla was chosen as the ideal site for comfortable, convenient incubation. Using commonly available materials, 3 methods for securing RPA reactions to the body were characterized. Finally, RPA reactions were incubated using body heat while control RPA reactions were incubated in a heat block. At room temperature, all reactions with 10 copies of HIV-1 DNA and 90% of reactions with 100 copies of HIV-1 DNA tested positive when incubated with body heat. In a cold room with an ambient temperature of 10 degrees Celsius, all reactions containing 10 copies or 100 copies of HIV-1 DNA tested positive when incubated with body heat. These results suggest that human body heat may provide an extremely low-cost solution for incubating RPA reactions in low resource settings.
One such isothermal platform, recombinase polymerase amplification (RPA), offers significant advantages for both instrumentation and assay development. RPA is tolerant to impure samples, amplifies DNA to detectable levels in as few as 5 minutes, and is available in a lyophilized form that can be transported to the point of care without requiring cold chain storage [7], [13], [14]. Lateral flow strips may be used for detection of amplified RPA products in low resource settings. In addition, RPA operates at a wide range of temperatures [7]. TwistDx recommends an incubation temperature of 37 degrees Celsius (the temperature of the human body) but notes that amplification may occur at temperatures as low as 25 degrees Celsius by using additional magnesium acetate, extending incubation time, and agitating reactions later in the incubation period [13]. Others have shown that even without adjusting the biochemistry of reactions, RPA retains reliable functionality between 31 and 43 degrees Celsius [15]. Although the possibility of incubating RPA reactions using body heat has been mentioned in previous work [5], [16], to the best of our knowledge, there are no examples of harnessing body heat to perform RPA in the literature.
In this paper, we explored the feasibility of using body heat to incubate RPA reactions for amplification of HIV-1 DNA. We chose this assay because detection of HIV-1 proviral DNA is an established method for early infant diagnosis [17], and the HIV-1 DNA RPA assay used here has been well-characterized elsewhere [18]. First we measured the temperature of mock reactions incubated at 4 body locations chosen to allow comfortable, convenient incubation. After demonstrating that the axilla is the ideal location for incubation, we investigated 3 commonly available materials to secure RPA reactions to the body. We also studied the effect of ambient conditions on incubation temperature to determine the ambient temperature range for which incubation with body heat may be feasible. Finally, RPA reactions were incubated using body heat while control RPA reactions were incubated in a heat block to demonstrate that body heat may be harnessed to enable isothermal amplification of HIV-1 DNA.
To allow convenient incubation of RPA reactions under the arm, several methods were tested for securing tubes to the body. Mock reactions were secured by wrapping a 10 cm wide bandage ($12, CVS Pharmacy, USA), applying a 5 cm wide elastic sweat band ($1, Academy Sports and Outdoors, USA), and tying an 8 cm wide strip of cotton cloth (African chitenje fabric, approximately $4 per yard, outdoor market, Malawi) over the shoulder and under the arm (Figure 1). Volunteers incubated a tube containing 50 µL of water for 45 minutes using each method while the temperature was measured as previously described. These measurements were taken for five volunteers.
The temperature of mock RPA reactions was measured at various body locations to estimate the temperature that an RPA reaction would reach if incubated using body heat. Figure 2 shows the temperature traces of mock RPA reactions incubated by 5 volunteers at 4 body locations. Mock reactions held in the axilla outside of clothing (Fig. 2A), taped to the abdomen under clothing (Fig. 2B), placed in a rear trouser pocket (Fig. 2C), and held in a closed fist (Fig. 2D) had average temperatures of 34.80.6, 31.31.7, 33.10.5, and 33.42.7 degrees Celsius, respectively. In less than three minutes, all mock reactions reached a temperature of 31 degrees Celsius, the temperature required for all RPA reactions to amplify DNA to detectable levels [15]. Because the temperature of mock reactions was closest to the temperature recommended for RPA (37 degrees Celsius) when incubated in the axilla, this site was chosen as the site of incubation for all following experiments.
