Moderate-intensity running (treadmill velocity of 21 m/min) increased blood lactate and actived transforming growth factor-β (TGF-β) concentration in rat cerebrospinal fluid (CSF). On the other hand, low-intensity running (15 m/min) did not increase blood lactate and caused no change in CSF TGF-β. Intraperitoneal (i.p.) administration of lactate to anesthetized rats caused an increase in blood lactate similar to that observed after a 21 m/min running exercise and increased the level of active TGF-β in CSF. Intraperitoneal administration of lactate at the same dose to awake and unrestricted rats caused a decrease in the respiratory exchange ratio, that is, enhancement of fatty acid oxidation and depression of spontaneous motor activity (SMA). Given that intracisternal administration of TGF-β to rats has been reported to enhance fatty acid metabolism and to depress SMA, we surmise that the observed changes caused by i.p. lactate administration in this study were mediated, at least in part, by TGF-β in the brain.

Objectives: To investigate the risk factors for plastic bronchitis (PB) in children with macrolide-unresponsive pneumonia (MUMPP) and to establish a nomogram prediction model.
Methods: A retrospective analysis was conducted on 178 children with MUMPP who underwent bronchoscopy from January to December 2023. According to the presence or absence of PB, the children were divided into a PB group (49 children) and a non-PB group (129 children).

Background: Low-volume hypertonic solutions, such as half-molar lactate (LAC), may be a potential treatment used for fluid resuscitation. This study aimed to evaluate the underlying cardiovascular effects and mechanisms of LAC infusion compared to sodium-matched hypertonic sodium chloride (SAL).
Methods: Eight healthy male participants were randomized in a controlled, single-blinded, crossover study.

Background: Our aim was to develop a quantitative model for immediately estimating the risk of death and/or brain injury in late-onset sepsis (LOS) in preterm infants, based on objective and measurable data available at the time sepsis is first suspected (i.e., time of blood culture collection).

Current hemodialysis treatments can cause adverse effects, many of which are linked to the membranes used in the process. These issues are being addressed through new materials and technologies, making it urgent to establish minimum guidelines for evaluating such membranes. This review proposes standardizing the biological tests and variables to evaluate the performance of new membranes, aiming to replicate hemodialysis conditions closely.

Drug-induced hemolytic anemia (DIHA) is a rare but significant condition characterized by the premature destruction of red blood cells (RBCs) triggered by certain medications. Ceftriaxone, a commonly used antibiotic, has been linked to DIHA, presenting diagnostic challenges due to its diverse clinical manifestations. This study examines three cases of DIHA caused by ceftriaxone therapy at our center.
