Anesthesia is one of the most valued discoveries in all of history. Almost immediately after the first public demonstration of ether anesthesia, a search for a better drug began. Ether, despite its flammability, persisted as the primary inhalation agent for over a hundred years. The breakthrough came with the introduction of a non-flammable volatile anesthetic called halothane in 1955. The drug was approved by the FDA in 1958 and quickly became the most commonly used agent in the United States. It was a quantum leap forward in the safety of anesthetic drugs. It became obsolete in 1988 because of hepatotoxicity. Three eminent anesthesiologists: Drs. Abajian of Vermont, Siker of Pittsburgh and Stephen of Duke could have been the first to use halothane in the USA. My review of the documents and writings of the three confirm that Dr. C. Ronald Stephen of Duke University was indeed the first to use and publish on halothane anesthesia in the USA.

Background: Giant cell arteritis (GCA) is the most common vasculitis in patients older than 50 years and is considered a "do not miss" diagnosis. However, it remains a diagnostic challenge given overlapping clinical syndromes such as non-arteritic anterior ischemic optic neuropathy (NAION) and poorly explored imaging findings.
Materials And Methods: In this retrospective study between the time period of January 2013 and December 2021, a total of 13 consecutive patients with a pathological diagnosis of GCA and 8 patients with clinical diagnosis of NAION were isolated.

While the content of subjective (personal) experience is inaccessible to external observers, behavioral proxies can frame the nature of that experience and suggest its cognitive requirements. Directed attention is widely recognized as a feature of animal awareness. This descriptive study used the frequency of gaze shifts in lizards and birds as an indicator of the rate at which the animals change the perceptual segmentation of their ongoing experience.

We introduce two Korean-named yet transcultural feelings, and , to fill gaps in neuroscientific understanding of mammalian bondedness, loss, and aggression. is a visceral sense of connectedness to a person, place, or thing that may arise after proximity, yet does not require intimacy. The brain opioid theory of social attachment (BOTSA) supports the idea that involves increased activity of enkephalins and beta-endorphins.

This study investigates the acquisition of sentence focus in Russian by adult English-Russian bilinguals, while paying special attention to the relative contribution of constituent order and prosodic expression. It aims to understand how these factors influence perceived word-level prominence and focus assignment during listening. We present results of two listening tasks designed to examine the influence of pitch cues and constituent order on perceived word prominence (Experiment 1) and focus assignment (Experiment 2) during the auditory comprehension of SV[O] and OV[S] sentences in Russian.
