Surgical tables employing lordosis adjustment subassemblies connected by hinge portions to rigid support frames, and related systems and methods are disclosed. A surgical table includes a frame supporting a patient in a prone position through subassemblies including body and leg pads. Relative positions of the pads determine a lumbar sagittal lordosis for the patient, and movements of the frame may disrupt a sterile field during surgery and increase opportunities for infections. By rotatably coupling the leg pad as part of a lordosis adjustment subassembly to the frame, a distal end of the leg pad may pass through an inner space defined by the frame to change the relative position of the pads according to the surgical procedures performed while minimizing frame movement. In this manner, post-operative long-term patient outcomes may be improved by providing optimal degrees of lordosis for the surgical procedures occurring during a surgical visit while minimizing infections.

The invention provides methods and related products for extracting nucleic acids such as DNA from prokaryotic spores. The invention also encompasses methods for identifying the source of such spores via analysis of the isolated nucleic acids.

Disclosed herein is a composition comprising a substrate with functionalized surface covalently bound to an anti-infective agent, such as a quaternary phosphonium compound with anti-bacterial activity against a broad range of bacteria, methods of synthesizing an anti-infective composition, and its resultant antimicrobial performance.

In one or more embodiments, the present invention provides a method of forming compact, flexible, stable and biocompatible conducting polymer coating for bioelectronics devices. In one or more embodiments, the present invention relates to a novel method of synthesizing a sulfobetaine-functionalized conjugated polymer platform using 3,4-ethylenedioxythiophene (EDOT) as the conducting backbone (SBEDOT). This SBEDOT monomer is highly water-soluble and can be directly polymerized to form a densely packed film / coating on conductive or semi-conductive surfaces through electro-polymerization in a 100% aqueous solution without the need for organic solvents or surfactants. These polySBEDOT (PSBEDOT) coated surfaces have been shown to have electro-switchable antimicrobial / antifouling properties and excellent electrically conducting properties, which minimize infection, increase biocompatibility, and improve the performance of bioelectronics.

A method and an apparatus for applying an anesthetic include an elongated tubular housing having an upper end, a substantially hollow interior, and a lower end having an injection needle extending therefrom. A first chamber is formed within the housing interior for holding an anesthetic cartridge therein. A second chamber receives a cannister containing an endothermic gas that rapidly absorbs heat when released to the atmosphere. The cartridge is penetrated by a plunger that forces the anesthetic through the injection needle. A depressible trigger propels the gas through an outlet nozzle that is oriented to project a stream of gas along a delivery axis that intersects a delivery axis of the needle; therefore, the gas and anesthetic can be successively delivered to an injection site with minimal repositioning of the housing. Accordingly, a dental practitioner can initially disperse the endothermic gas onto the injection site to minimize any pain and discomfort associated with an injection. Subsequently, the practitioner inserts the needle into the deadened site and injects the anesthetic.
