Progressive myoclonus epilepsy (PME) comprises a group of rare heterogeneous genetic disorders that are generally manifested as a combination of myoclonic and tonic-clonic seizures with cognitive impairment, ataxia and other cerebellar signs, and other neurologic deficits. They are often encompassed under the broader term "catastrophic epilepsies", which are invariably associated with significant neurological morbidity and often early mortality. This group also include epileptic encephalopathies [1].

Publication date: Available online 17 April 2019Source: Neurochemistry InternationalAuthor(s): Debapriya Garabadu, Jaya VermaAbstractAlzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by memory loss, disorientation and gradual deterioration of intellectual ability. In the pharmacotherapy of AD, the mitochondrial protective activity of Exendin-4 in experimental studies is yet to be established though its effectiveness is demonstrated in these patients. Therefore, the mitochondria protective activity of Exendin-4 (5 μg/kg, i.p.) was investigated in hippocampus and pre-frontal cortex (PFC)...

Conclusion The m.10191T>C mutation in the mtDNA of the complex I (CI) subunit of MTND3 results in the substitution of a highly conserved amino acid (p.Ser45Pro) within the ND3 protein, leading to CI dysfunction through impaired enzyme catalysis rather than impaired stability or assembly, causing a broad clinical spectrum of disorders (26). Patients with the m.10191T>C mutation are rare. In the present study, we report on a family of patients with the extremely rare adult-onset Leigh-like syndrome with the m.10191T>C mutation. Including the two patients from our reported family, the m.10191T>C mutation has bee...

In this study we show that different level of the neuronal activity can trigger Ca2+ dynamics in astrocyte with various spatio-temporal characteristics which can lead to different astrocytic-induced regulatory effects on synaptic transmission. The minimal synaptic activity causes the fast and local Ca2+ elevation in astrocytic process. This small Ca2+ signal triggers the gliotransmission in the active synapse induces localized regulatory astrocytic feedback of the synapse (Figure 6). Increasing frequency of synaptic activity can produce Ca2+ signal which can spread to another astrocytic process (Figure 7) and to the whole ...

In this study, we: (1) estimated the incidence of CML in our study sample; (2) identified indicators of cognitive reserve (e.g., indicators of educational attainment, social support); and (3) determined whether CML is associated with cognitive reserve level, stratified by PSTD status. First, we described demographics of the study sample (n = 14,574) and probable PTSD status, also stratifying by CML. Next, we conducted a latent class analysis on two groups: those with probable PTSD and those without probable PTSD, creating classes with varying cognitive reserve levels. Finally, using adjusted log binomial models, we predict...
