Localization of the greater occipital nerve through palpation of bony landmarks: A cadaveric study.

Objective: to provide anatomic confirmation that standard methods which practitioners skilled in palpation use, can reliably identify the most likely site of emergence of the greater occipital nerve in most patients. The location and frequency of subcutaneous emergence of the greater occipital nerve and occipital artery with respect to the external occipital protuberance-mastoid line are reported.

Methods: The external occipital protuberance and the mastoid processes were identified by palpation bilaterally on 57 body donors and the medial trisection point of a line connecting these bony landmarks was identified.

Drunken lipid membranes, not drunken SNARE proteins, promote fusion in a model of neurotransmitter release.

Alcohol affects many neuronal proteins that are upstream or down-stream of synaptic vesicle fusion and neurotransmitter release. Less well studied is alcohol's effect on the fusion machinery including SNARE proteins and lipid membranes. Using a SNARE-driven fusion assay we show that fusion probability is significantly increased at 0.

Closed Fracture Treatment in Adults, When is it Still Relevant?

Introduction: Fracture treatment has been documented since the times of ancient Egyptian and Greek civilization, with fracture reduction techniques and the apparatus for immobilization developed over three millennia. Over the last 150 years, aseptic technique, anesthesia, antibiotics, and internal implants have changed how orthopedic specialists approach fracture care. More recently, there has been an increased promotion in the medical literature to evaluate the clinical outcomes of nonsurgical treatment of common upper and lower extremity closed fractures.

Infection after the use of INFIX in Pelvic Ring Injuries.

Introduction: The purpose of this study is to report on infection with anterior subcutaneous internal pelvic fixation (INFIX) for pelvic ring injuries and the outcomes of treatment.

Methods: An IRB-approved retrospective study was performed using trauma databases of a level one and level two trauma center from 2012-2018. Infection after the INFIX procedure was diagnosed in 10 of 179 cases.

A review of TNP-ATP in protein binding studies: benefits and pitfalls.

We review 50 years of use of 2',3'-O-trinitrophenyl (TNP)-ATP, a fluorescently tagged ATP analog. It has been extensively used to detect binding interactions of ATP to proteins and to measure parameters of those interactions such as the dissociation constant, K, or inhibitor dissociation constant, K. TNP-ATP has also found use in other applications, for example, as a fluorescence marker in microscopy, as a FRET pair, or as an antagonist (e.
