Inflammation of the uterus and oviduct is associated with reduced reproductive performance in humans and domestic animals. Toll-like receptors are expressed in various immune and non-immune cells and play a crucial role in innate immunity. Toll-like receptor - 4 (TLR4) can detect lipopolysaccharide (LPS) from Gram-negative bacteria leading to the secretion of pro-inflammatory cytokines, chemokines, antimicrobial peptides and other inflammatory mediators. To investigate the effects of a local inflammation on the expression levels of TLR4 and pro-inflammatory cytokines, 12 female rabbits received an intracervical infusion with either saline solution endotoxin-free (carrier, 2 mL; n = 6) or LPS (500 μg diluted in 2 mL of saline solution; n = 6)...

BACKGROUND: Extracellular volume (ECV) by T1 mapping requires the contrast agent distribution to be at equilibrium. This can be achieved either definitively with a primed contrast infusion (infusion ECV), or sufficiently with a delay postbolus (bolus-only ECV). For large ECV, the bolus-only approach measures higher than the infusion ECV, causing some uncertainty in diseases such as amyloidosis. PURPOSE: To characterize the relationship between the bolus-only and current gold-standard infusion ECV in patients with amyloidosis...

PURPOSE: Great heterogeneity exists in the ability of adults with cancer to tolerate chemotherapy. Variability in body composition may affect rates of metabolism of cytotoxic agents and contribute to the variable chemotherapy toxicity observed. The objective of this exploratory study was to examine the association of low skeletal muscle, commonly known as sarcopenia, on the pharmacokinetics (PKs) of 5-fluorouracil (5FU) in patients receiving FOLFOX for colorectal cancer. METHODS: We performed a secondary analysis of a completed multicenter trial that investigated PK-guided 5FU dosing in patients receiving mFOLFOX6 +/- bevacizumab for colorectal cancer...

Neuropeptide S (NPS) is a regulatory peptide that has anxiolytic and arousal-promoting effects in rodents. We used an animal model of posttraumatic stress disorder (PTSD) to assess long-term behavioral effects of a single dose of NPS, microinjected into the basolateral amygdala (BLA) 1h following exposure to predator-scent stress (PSS). To elucidate the molecular mechanism by which NPS attenuates behavioral stress responses, expression levels of neuropeptide Y (NPY), NPY-Y1 receptor (NPY-Y1R), and brain-derived neurotrophic factor (BDNF) were evaluated in the hippocampus...

The objective of this consensus-based S1 Guideline for perioperative fluid therapy in children is to maintain or re-establish the child's homeostasis. Therefore, the perioperative fasting times should be as short as possible to prevent patient discomfort, dehydration, and ketoacidosis. For the intraoperative background infusion a physiologically composed balanced isotonic electrolyte solution (BS) with 1 - 2.5% glucose is recommended to maintain normal glucose concentrations and to avoid hyponatremia, hyperchloremia, and lipolysis...

Dysbiosis plays a major role in the etiology of inflammatory bowel disease (IBD). Fecal microbiota transplantation (FMT) is a new promising option for IBD treatment. We aimed to assess the effectiveness of a two-week FMT course in children with IBD. Ten patients, 10-17 years of age with moderate to severe IBD received a course of eight doses of freshly prepared FMT via a naso-duodenal tube or gastroscopy. All of the patients had pancolitis. There were eight cases of ulcerative colitis (UC) and two of Crohn's disease (CD)...

INTRODUCTION: During brain tumour surgery, vasopressor drugs are commonly administered to increase mean arterial blood pressure with the aim of maintaining sufficient cerebral perfusion pressure. Studies of the commonly used vasopressors show that brain oxygen saturation is reduced after phenylephrine administration, but unaltered by ephedrine administration. These findings may be explained by different effects of phenylephrine and ephedrine on the cerebral microcirculation, in particular the capillary transit-time heterogeneity, which determines oxygen extraction efficacy...

CONTEXT: Since the banning of dextropropoxyphene from the market, overdoses, and fatalities attributed to tramadol, a WHO step-2 opioid analgesic, have increased markedly. Tramadol overdose results not only in central nervous system (CNS) depression attributed to its opioid properties but also in seizures, possibly related to non-opioidergic pathways, thus questioning the efficiency of naloxone to reverse tramadol-induced CNS toxicity. OBJECTIVE: To investigate the most efficient antidote to reverse tramadol-induced seizures and respiratory depression in overdose...
