Modulation of catalase, copper and zinc in the hippocampus and the prefrontal cortex in social isolation-induced depression in male rats

depression in socially isolated people is not fully understood. In this study, we hypothesized that fourteen days of social isolation would lead to a reduction in zinc and copper levels and catalase activity in the hippocampus and prefrontal cortex that may contribute to the occurrence of depression. The prefrontal cortex is a brain region often investigated in psychiatric illnesses (Vostrikov et al., 2007). The hippocampus is also of particular importance for studying depressive and anxiety behavior

The effect of bupropion augmentation of minocycline in the treatment of depression

It was conducted using the HPLC (Shimadzu, LC-2010C HT) with FD (RF-20A-prominence, Shimadzu) method (Lakshmana and Raju, 1997; Choudhary et al., 2013; Kale et al., 2014). Approximately 1 h before euthanasia, mice were treated. After performing the TST at a 30 min interval, mice heads were dropped in 0.1 M perchloric acid at

Moderate exercise prevents the cell atrophy caused by hypothyroidism in rats

hippocampus in both rats (Alva-Sánchez et al., 2009a) and humans (Cooke et al., 2014). Hypothyroid rats show reductions in the total weight of the hippocampus and in the volume on the Ammon’s horn (Madeira et al., 1992), which is consistent with an increase in the proportion of atrophic neurons in this region (Alva-Sánchez et al., 2009b; Khordad et al., 2018) and a reduction of the number of pyramidal cells particularly in CA1 (Madeira et al., 1992). Along with this, dendritic arborization and dendritic

Briefly, under deep anesthesia by intraperitoneal injection of ketamine/xylazine (100 mg/kg and 10 mg/kg, respectively), the brains were removed and the dissected hippocampi washed in the ice-cold phosphate-buffered saline (PBS, Gibco), supplemented with 4.5 g/L

Additionally, 3 h after STZ injections, disruption of working memory has been observed followed by degenerative processes in the hippocampus at 1 and 15 days after STZ injections. Furthermore, memory disruptions increase over time (Santos et al., 2012) as demonstrated by mice that received icv-STZ and showed impairment in learning and spatial memory 21 days after STZ administration (Chen et al., 2012). Bao and coworkers (2017) also found that icv-STZ remarkably induced

Possible role of hippocampal GPR55 in spatial learning and memory in rats

Endocannabinoids (eCBs) are involved in the hippocampal mechanisms of spatial learning and memory in rats. Although eCBs exert many of their actions on spatial learning and memory via CB1 receptors, the putative cannabinoid receptor GPR55 (expressed in the hippocampus, cortex, forebrain, cerebellum and striatum) seems to be also involved. To investigate the potential role of GPR55 in spatial learning and memory, Wistar rats received bilateral infusions of lysophosphatidylinositol (LPI, GPR55

Experimental studies have confirmed the potential effects of MPH on neurodegeneration of several brain areas including the hippocampus, which is involved in cognition and anxiety (Andreazza et al., 2007; Jones and

However, the nose-pokes performed during the last (i.e., test) session that were accompanied with flat 50 kHz calls correlated positively with the number of c-Fos-positive nuclei in the CA1 region of the hippocampus (r=0.50, p<0.05). This correlation was stronger in the experimental group (r=0.84, p<0.05) and was not observed in the control rats. Finally, since short 22 kHz USV and flat 50 kHz calls seemed to follow a similar pattern and were both associated with the

Edaravone (18 mg/kg) treatment did not prevent hyperlocomotion in the mania model induced with ketamine in rats, but lithium chloride (47.5 mg/kg, i.p., positive control) did prevent hyperlocomotion. Edaravone and lithium chloride treatments were found to reduce the increase in SOD and CAT

Changes in neurogenesis with post-hatching age in the male Japanese quail (Cortunix japonica) brain

were also observed in the hippocampus and bed nucleus of stria terminalis. The density of PCNA-ir cells and DCX-ir cells in all brain areas declined with post-hatching age. In conclusion, cell proliferation appears to be restricted to the ventricular zones whereas neuronal recruitment is more widespread in the olfactory bulb, telencephalon and cerebellum. Postnatal neuronal incorporation appears to be absent in the diencephalon and mesencephalon.

Antimuscarinic-induced convulsions in fasted mice after food intake: no evidence of spontaneous seizures, behavioral changes or neuronal damage

Prolonged or repeated seizures have been shown to cause spontaneous recurrent seizures, increased anxiety-related behavior, locomotor hyperactivity, impaired functions of learning and memory, and neuronal damage in the hippocampus and other brain regions in animals. Mice and rats treated with antimuscarinic drugs after fasting for two days or less develop convulsions after being allowed to eat ad libitum. To address whether such behavioral and neuroanatomic changes occur following these

Cell-based immunofluorescence assay for screening the neurogenesis potential of new drugs in adult hippocampal neural progenitor cells

Substantial neurogenesis and continuous supplementation of newborn neurons in the hippocampus and striatum of human adults indicate that neurogenesis may have important implications for brain function (Bergmann et al., 2015; Boldrini et al., 2018). Adult neurogenesis in the hippocampus is important for memory coding and mood regulation. Furthermore, alterations in adult neurogenesis are associated with several brain diseases, such as neurodegenerative diseases, ischemic stroke, and psychiatric
