Stress is a major risk factor for psychiatric disorders, such as depression, posttraumatic stress disorder, and schizophrenia. Early life stress, such as maternal separation, can have long-term effects on the development of the central nervous system and pathogenesis of psychiatric disorders. In the present study, we found that maternal separation increased the susceptibility to stress in adolescent rats, increased the expression of Na(+)/K(+)/2Cl(-) cotransporter 1 (NKCC1) on postnatal day 14, and increased the expression of K(+)/2Cl(-) cotransporter 2 (KCC2) and γ-aminobutyric acid A (GABAA) receptor subunits on postnatal day 40 in the hippocampus...

BACKGROUND: Few data are available regarding the use of metolazone in infants in cardiac intensive care. Researchers need to carry out further evaluation to characterise the effects of this treatment in this population. METHODS: This is a descriptive, retrospective study carried out in patients less than a year old. These infants had received metolazone over a 2-year period in the paediatric cardiac intensive care unit at our institution. The primary goal was to measure the change in urine output from 24 hours before the start of metolazone therapy to 24 hours after...

The cortical collecting duct (CCD) forms part of the aldosterone-sensitive distal nephron and plays an essential role in maintaining the NaCl balance and acid-base status. The CCD epithelium comprises principal cells as well as different types of intercalated cells. Until recently, transcellular Na+ transport was thought to be restricted to principal cells, while (acid-secreting) type A and (bicarbonate-secreting) type B intercalated cells were associated with the regulation of acid-base homeostasis. This review describes how this traditional view has been upended by several discoveries in the last decade...

BACKGROUND/AIM: The aim of this study was to determine whether the addition of bumetanide (BU), a glycolytic metabolism pathway inhibitor, to arterial embolization improves tumor necrosis of N1-S1 hepatocellular carcinoma in a rat model. MATERIALS AND METHODS: N1-S1 tumors were surgically implanted in the liver of 14 Sprague-Dawley rats. The rats were divided into three groups: In control group (n = 5), 1 ml of normal saline was injected intra-arterially. The tumor in the transarterial embolization group (TAE, n = 4) was embolized using 10 mg of 50-150 μ polyvinyl alcohol (PVA) particles and embolization plus BU group (TAE + BU, n = 5) were embolized with 10 mg of PVA plus 0...

Several reports have described excitatory GABA transmission in the suprachiasmatic nucleus (SCN), the master pacemaker of circadian physiology. However, there is disagreement regarding the prevalence, timing, and neuronal location of excitatory GABA transmission in the SCN. Whether GABA is inhibitory or excitatory depends, in part, on the intracellular concentration of chloride ([Cl(-)]i). Here, using ratiometric Cl(-) imaging, we have investigated intracellular chloride regulation in AVP and VIP-expressing SCN neurons and found evidence suggesting that [Cl(-)]i is higher during the day than during the night in both AVP+ and VIP+ neurons...

In this study we have used an antibody that specifically detects the phosphorylation status of the Sodium/Potassium/2 Chloride Cotransporter (NKCC1) to study whether the activity of NKCC1 can be regulated in organ cultured bovine lenses. Western blotting was first used to confirm the expression of NKCC1, phosphorylated NKCC1 (NKCC1-P) and the regulatory kinases WNK/SPAK and phosphatases PP1/PP2A in bovine lenses at the protein level. Changes to NKCC1-P status were then assessed by organ culturing bovine lenses in either isotonic, hypertonic or hypotonic solutions in the presence or absence of the NKCC inhibitor, bumetanide, or phosphatase inhibitors okadaic acid and calyculin A...

In physiological conditions, adult neurons have low intracellular Cl(-) [(Cl(-))I] levels underlying the γ-aminobutyric acid (GABA)ergic inhibitory drive. In contrast, neurons have high (Cl(-))I levels and excitatory GABA actions in a wide range of pathological conditions including spinal cord lesions, chronic pain, brain trauma, cerebrovascular infarcts, autism, Rett and Down syndrome, various types of epilepsies, and other genetic or environmental insults. The diuretic highly specific NKCC1 chloride importer antagonist bumetanide (PubChem CID: 2461) efficiently restores low (Cl(-))I levels and attenuates many disorders in experimental conditions and in some clinical trials...

Neonatal seizures constitute the most frequent presenting neurologic sign encountered in the neonatal intensive care unit. Despite limited efficacy and safety data, phenobarbital continues to be used near-universally as the first-line anti-seizure drug (ASD) in neonates. The choice of second-line ASDs varies by provider and institution, and is still not supported by sufficient scientific evidence. In this review, we discuss the available evidence supporting the efficacy, mechanism of action, potential adverse effects, key pharmacokinetic characteristics such as interaction with therapeutic hypothermia, logistical issues, and rationale for use of neonatal ASDs...

BACKGROUND: Animal models when carefully selected, designed and conducted, are important parts of any translational drug development strategy. However, research of new compounds for patients with drug-resistant epilepsies is still based on animal experiments, mostly in rodents, which are far from being a model of chronic human epilepsy and have failed to differentiate the efficacy of new compounds versus standard drug treatment. Objective The objective was identification and description of compounds in clinical development in 2016...

REVIEW

Seizures are common in neonates with moderate and severe hypoxic ischemic encephalopathy (HIE) and are associated with worse outcomes, independent of HIE severity. In contrast to adults and older children, no new drugs have been licensed for treatment of neonatal seizures over the last 50 years, because of a lack of controlled clinical trials. Hence, many antiseizure medications licensed in older children and adults are used off-label for neonatal seizure, which is associated with potential risks of adverse effects during a period when the brain is particularly vulnerable...

The choroid plexus epithelium (CPE) secretes higher volumes of fluid (cerebrospinal fluid, CSF) than any other epithelium and simultaneously functions as the blood-CSF barrier to gate immune cell entry into the central nervous system. Posthemorrhagic hydrocephalus (PHH), an expansion of the cerebral ventricles due to CSF accumulation following intraventricular hemorrhage (IVH), is a common disease usually treated by suboptimal CSF shunting techniques. PHH is classically attributed to primary impairments in CSF reabsorption, but little experimental evidence supports this concept...

Traumatic brain injury (TBI) can lead to long-term motor and cognitive dysfunction, which can be at least partly attributed to blood-brain barrier (BBB) disruption. The mechanisms underlying post-TBI BBB disruption, however, are poorly understood thus far. Na(+)-K(+)-2Cl(-) cotransporter isoform 1 (NKCC1) is a universally expressed ion transporter that maintains intracellular ion homeostasis by increasing intracellular K(+) and Cl(-). Having been characterized in stroke models, NKCC1 is activated in various cell types in the ischemic brain, and is thought to mediate BBB disruption, brain edema, and neuronal cell death...

Monocarboxylate transporter 6 (MCT6; SLC16A5) has been recognized for its role as a xenobiotic transporter, with characterized substrates probenecid, bumetanide, and nateglinide. To date, the impact of commonly ingested dietary compounds on MCT6 function has not been investigated, and therefore, the objective of this study was to evaluate a variety of flavonoids for their potential MCT6-specific interactions. Flavonoids are a large group of polyphenolic phytochemicals found in commonly consumed plant-based products that have been recognized for their dietary health benefits...

BACKGROUND: Astaxanthin (ATX) is a carotenoid pigment with pleiotropic pharmacological properties that is seen as a possible drug for treating cerebral ischemic injury and subarachnoid hemorrhage. Na(+)-K(+)-2Cl(-) co-transporter-1 (NKCC1), an intrinsic membrane protein expressed by many cell types, is activated by various insults, leading to the formation of cell swelling and brain edema. We previously established that ATX attenuated brain edema and improved neurological outcomes by modulating NKCC1 expression after traumatic brain injury in mice...

Uropathogenic Escherichia coli often produce the virulence factor α-hemolysin (HlyA), and the more severe the infection, the likelier it is to isolate HlyA-producing E. coli from patients. HlyA forms pores upon receptor-independent insertion of the toxin into biological membranes and it has been substantiated that HlyA-induced hemolysis is amplified by toxin-induced ATP release and activation of P2X receptors. Thus, hemolysis inflicted by HlyA is a protracted process involving signal transduction. It consists of early, marked cell shrinkage followed by swelling and eventually lysis...
