N-glycans Profiling in Pilocarpine Induced Status Epilepticus in Immature Rats

Publicado en línea: 11 Aug 2022
Páginas: 1 - 4

Resumen

Abstract

Status epilepticus (SE) is a common neurological emergency in children and a well-known epileptogenic insult. Neonates are extremely susceptible to seizures in the neonatal period due to the higher vulnerability. Neonatal SE is associated with significant mortality and morbidity. There is an evident need for attention on neonatal SE in research due to the incredibly limited diagnostic and treatment options in current neonatology, and its serious long-term consequences. The aim of the present study was to characterize the glycoprofiles in the pilocarpine-induced SE model in immature rats to assess the overall N-glycans composition. To induce lithium-pilocarpine (Li-Pilo) SE male Wistar rat pups were pretreated with lithium chloride (127 mg/kg, n=11) on the 11th postnatal day. After 24 hours, the lithium pre-treated pups were administered either with pilocarpine intraperitoneally (i.p.) (35 kg/g, n=6) or saline (n=5) in the control group (Control). On the 19th postnatal day, serum was collected and the analytical procedures were done by mass spectrometry (MS) analytics on matrix-assisted laser desorption/ionization in combination with a time-of-flight detector (MALDI-TOF/MS). Analyzed data were processed by FlexAnalysis (Bruker Daltonics) and GlycoWorkbench software. There were 21 N-glycans that were identified, appointed, and sorted with special emphasis on their structure. We have demonstrated the significant changes in terms of N-glycans sialylation in Li-Pilo compared to the Control. We also observed some other remodelation trends in different portions of relative intenstities of N-glycan clusters according to their glycan type. Our preliminary findings have laid the foundation for additional investigation into glycosylation alterations in the SE in immature rats.

Anthocyanin-Rich Extract of Red Cabbage Attenuates Advanced Alcohol Hepatotoxicity in Rats in Association with Mitochondrial Activity Modulation

Publicado en línea: 23 Aug 2022
Páginas: 5 - 16

Resumen

Abstract Aim

The liver is the main target for alcohol-induced injury. The aims of this work were to carry out further research into the mechanisms of liver damage induced by long-term administration of high-dose ethanol to rats and to evaluate the hepatoprotective potential of red cabbage (Brassica oleracea var. capitata f. rubra) anthocyanins (RCE).

Material/Methods

Male albino Wistar rats were divided into four groups. Group 1 was the control. Groups 2 through 4 received ethanol (4 g/kg body weight, 8 weeks). Group 3 received 11 mg RCE/kg and Group 4 received 22 mg RCE/kg. Dry lyophilised RCE was prepared from fresh red cabbage and analysed. We then evaluated the liver histology, mitochondrial respiration, and biochemical and immunological parameters in these groups of rats.

Results

The rat intoxication caused steatohepatitis characterised by macro- and microvesicular steatosis, ballooning and fatty liver dystrophies, lymphocytic infiltration, neutral lipid accumulation, and elevations of the serum activities of the liver injury marker enzymes. The treatment of alcohol-administered rats with RCE (mainly, cyanidin-3-diglucoside-5-glucoside, cyanidin-3-coumaroylrutinoside-5-hexoside, cyanidin-3-feruloylrutinoside-5-hexoside, delphinidin-3-feruloylrutinoside-hexoside) dose-dependently alleviated these pathological changes: The sizes of hepatocyte lipid vacuoles and the inflammatory signs were decreased, and the levels of the rat serum biochemical markers of liver injury, proinflammatory cytokines TNFα and IL-6, and the adipokine leptin (and not TGFβ) were significantly reversed. The RCE administration during intoxication completely recovered the changed liver mitochondria respiration rates and the ADP/O coefficient, as well as the phagocytic index and neutrophil metabolic activity in the blood. In experiments in vitro, RCE (13.6 μg/ml) modulated the respiratory parameters of isolated rat liver mitochondria, dissipated mitochondrial membrane potential, and inhibited the Ca2+-induced mitochondrial permeability transition.

Conclusion

The red cabbage anthocyanins could be useful for treatment of alcoholic liver injury due to their Ca2+-ionophoric/protonophoric activity, influence on Ca2+ homeostasis, and improving mitochondrial functions and inflammatory status.

Retrospective Assessment of the Use of Pharmacotherapeutic Agents in Pregnancy with Potential Impact on Neonatal Health

Publicado en línea: 23 Aug 2022
Páginas: 17 - 25

Resumen

Abstract

This study focuses on the role of a clinical pharmacist in the optimisation of pharmacotherapy in the case of patients during pregnancy and its importance within the hospital sector in Slovakia. Retrospective evaluation of pharmacotherapy in pregnant patients with a focus on teratogenicity and appropriate drug selection was used. The hospital data were collected during 24 months from 22 female patients. The main observed outcome was health condition of the newborn, and it was expressed as healthy newborn, illness of the newborn, any congenital defect or malformation, spontaneous abortion, or unspecified information about the newborn. Based on a foetal risk assessment of used therapeutic agents from the Summary of Product Characteristics (SmPC), basal foetal and neonatal risk assessment (Briggs et al., 2017), and recommendations and related human past reports and supporting evidence studies, drugs were divided into two groups: confirmed foetal risk drugs and negative (nonconfirmed) foetal risk drugs. A total of 36.3% of the patients used two drugs. Patients most frequently used drugs during the first trimester (81.8%). During pregnancy, the most used drugs were for the nervous system (25.5%), anti-infective agents (23.6%), and respiratory therapeutic agents (14.5%). Of the 22 patients, 16 (73%) had healthy newborns, despite the use of therapeutic agents with different foetal-risk variations. In the group of therapeutic agents with confirmed risk, in some, negative effect on the newborn's health was clinically manifested. Spontaneous abortion was present after using norethisterone acetate and valproic acid; birth defect (unspecified) was present after usage of interferon β-1a and methylprednisolone sodium succinate. An illness (heart murmur) was present after the use of monohydrate sodium salt of metamizole. Another illness (Wilm's tumour) was present after the use of budesonide. Unspecified information about the newborn was observed in four cases after the use of prednisone, allopurinol, nadroparin, and fluvastatin.
