Six normally reared cats were trained on a three-choice delayed response task to visual stimuli. All cats mastered 1 min delay, three cats 2 min delay and one cat 6 min delay. Learning was much better than in previously studied cats reared in laboratory cages. It was comparable to that known for auditory stimuli in normally reared cats.

Background: The carbon-13 spirulina gastric emptying breath test (GEBT) is approved to identify delayed, but not accelerated, gastric emptying (GE). We compared the utility of the GEBT to scintigraphy for diagnosing abnormal GE in patients with diabetes mellitus.
Methods: Twenty-eight patients with diabetes ate a 230-kcal test meal labeled with technetium 99 m and C-spirulina, after which 10 scintigraphic images and breath samples (baseline, 15, 30, 45, 60, 90, 120, 150, 180, 210, and 240 min) were collected on 2 occasions 1 week apart.

Background: Myelomeningocele (MMC) is the most common type of congenital spinal malformation, typically requiring surgical intervention. While prenatal repair is increasingly favored, postnatal repair remains the standard in many settings. This study aims to evaluate the antibiotics prescribed to neonates with MMC and their correlation with central nervous system (CNS) infection rates following postnatal surgical repair.

Background: Awake prone positioning (APP) can reportedly reduce the need for intubation and help improve prognosis of patients with acute hypoxemic respiratory failure (AHRF) infected with COVID-19. However, its physiological mechanism remains unclear. In this study, we evaluated the effect of APP on lung ventilation in patients with moderate-to-severe AHRF to better understand the effects on ventilation distribution and to prevent intubation in non-intubated patients.

Introduction: Prolonged or strenuous exercise leads to a temporary decrease in muscle function and performance, which interferes with activity of both prime movers and postural muscles. This effect of fatigue has been reported both for single segment movements and for locomotion. However, little is known regarding the effects of fatigue on anticipatory postural adjustments (APAs) during gait initiation, a task in which the control of focal movement should be strictly coupled to a feedforward control of posture.

Drug-induced hyponatremia is an adverse reaction with accelerated electrolyte disturbance. This study reported a rare case of delayed hyponatremia in a 68year-old female with recurrent upper tract urothelial carcinoma after Gemcitabine plus Cisplatin (GC) and Tislelizumab treatment. She had left ureter surgery, recurrence a year later with mildly abnormal kidney function (glomerular filtration rate (GFR) was 54.
