The maintenance of extracellular fluid (ECF) osmolality and sodium concentration ([Na]) near optimal "set point" values sustains physiological functions and prevents pathological states such as hypo- and hypernatremia. The peptide hormones vasopressin (antidiuretic hormone) and oxytocin (a natriuretic hormone in rats) play key roles in this process. These hormones are synthesized by hypothalamic magnocellular neurosecretory cells (MNCs) that project to the neurohypophysis and are released into the systemic circulation in response to rises in ECF osmolality or [Na].

Department of Anesthesiology and Pain Management, Facultad de Ciencias Veterinarias, Universidad de Buenos Aires, Buenos Aires, Argentina.
Objective: To evaluate the effect of 5 cmHO positive end-expiratory pressure (PEEP) and end-inspiratory pause (EIP) on airway dead space (V) and its resultant effects on alveolar tidal volume (V) and physiological dead space-to-tidal volume ratio (V/V) in dorsally recumbent anesthetized dogs.
Study Design: Prospective, controlled clinical study.
Animals: Healthy adult dogs (n = 20, > 20 kg) undergoing elective surgery.

Statement Of Problem: The reproducibility of positioning the maxillary occlusal plane in an articulator with a facebow remains debated. Its clinical use is widespread, yet its reliability and clinical outcomes compared to other transfer methods under standardized conditions remain uncertain.
Purpose: The purpose of this in vitro study was to compare the intra-operator reproducibility of maxillary positioning on an articulator using a facebow compared to a standardized transfer table.

There is surprisingly little age-critical research on Ernest Hemingway's The Old Man and the Sea (1952), even though the novella seems like an obvious choice for age studies. This article reviews foundational concepts and approaches in age studies on gender, performativity, creativity and space and brings them into dialog with The Old Man and the Sea. In the first part, the representation of older age and gender is emphasized through an analysis of the intersectional and performative nature of the old man's aging masculinity, including a focus on the aesthetic choices which contribute to the novella's semantic complexity.

On the other hand, patients with severe dental phobias or with intellectual disability who have a severe gag reflex often require deeper levels of anesthesia. Thus, achieving an optimal level of anesthesia can be difficult in patients with cardiovascular compromise because of the relatively narrow range of sedative dosing capable of providing sufficient sedation to prevent the gag reflex without compromising hemodynamics.
