Objective: The primary objective of this retrospective analysis was to evaluate the incidence and lateralization value of peri-ictal yawning (PY) in people with temporal lobe epilepsy (TLE). PY has only occasionally been reported as a manifestation of focal epilepsy. We aimed to determine whether PY could serve as an indicator to help lateralize seizure onset during epileptic seizures.

Attentional control, guided by top-down processes, enables selective focus on pertinent information, while habituation, influenced by bottom-up factors and prior experiences, shapes cognitive responses by emphasizing stimulus relevance. These two fundamental processes collaborate to regulate cognitive behavior, with the prefrontal cortex and its subregions playing a pivotal role. Nevertheless, the intricate neural mechanisms underlying the interaction between attentional control and habituation are still a subject of ongoing exploration.

Background: Epilepsy stands as an intricate disorder of the central nervous system, subject to the influence of diverse risk factors and a significant genetic predisposition. Within the pathogenesis of temporal lobe epilepsy (TLE), the apoptosis of neurons and glial cells in the brain assumes pivotal importance. The identification of differentially expressed apoptosis-related genes (DEARGs) emerges as a critical imperative, providing essential guidance for informed treatment decisions.

Background: Posterior cortex epilepsy (PCE) primarily comprises seizures originating from the occipital, parietal, and/or posterior edge of the temporal lobe. Electroclinical dissociation and subtle imaging representation render the diagnosis of PCE challenging. Improved methods for accurately identifying patients with PCE are necessary.

Dravet syndrome (DS), previously known as severe myoclonic epilepsy in infancy (SMEI), is considered the most serious "epileptic encephalopathy." Here, we present a man with a de novo SCN1A mutation who was diagnosed with DS at the age of 29. In addition to pharmaco-resistant seizures and cognitive delay, he also developed moderate to severe motor and gait problems, such as crouching gait and Pisa syndrome.

We present an all-optical temperature sensor device made of an MXene VC integrated runway-type microfiber knot resonator (MKR) for the first time. MXene VC is coated on the surface of the microfiber by optical deposition. The experimental results show that the normalized temperature sensing efficiency is ∼1.

Objectives: Although hemispheric surgeries are among the most effective procedures for drug-resistant epilepsy (DRE) in the pediatric population, there is a large variability in seizure outcomes at the group level. A recently developed HOPS score provides individualized estimation of likelihood of seizure freedom to complement clinical judgement. The objective of this study was to develop a freely accessible online calculator that accurately predicts the probability of seizure freedom for any patient at 1-, 2-, and 5-years post-hemispherectomy.

The diterpenoid alkaloids are a family of extremely important natural products that have long been a research hotspot due to their myriad of intricate structures and diverse biological properties. This chapter systematically summarizes the past 11 years (2009-2019) of studies on the diterpenoid alkaloids, including the "so-called" atypical ones, covering the classification and biogenetic relationships, phytochemistry together with 444 new alkaloids covering 32 novel skeletons and the corrected structures, chemical reactions including conversion toward toxoids, synthetic studies, as well as biological activities. It should be noted that the synthetic studies, especially the total syntheses of various diterpenoid alkaloids, are for the first time reviewed in this treatise.

  • The study aimed to compare two surgical techniques—vertical parasagittal and lateral peri-insular/peri-Sylvian hemispherotomy—specifically to see which is better for achieving long-term seizure freedom in patients.* -
  • Data from 672 participants indicated that 62.4% achieved seizure freedom over 10 years, with the vertical approach showing higher long-term success rates: 88.8% at 1 year, diminishing to 85.5% at 5 and 10 years, while the lateral approach saw a decline from 89.2% to 57.2% over the same periods.* -

Article Synopsis
  • A study was conducted to create and validate a model that can predict seizure freedom in children undergoing hemispheric surgery for drug-resistant epilepsy, analyzing data from 1267 surgeries across 32 centers globally.
  • The results showed that 66% of patients achieved seizure freedom 3 months post-surgery, with a predictive model developed using factors like age at seizure onset and imaging results, achieving a moderately high predictive accuracy (area under the curve = .72).
  • The study introduced the Hemispheric Surgery Outcome Prediction Scale (HOPS), which helps identify children who will benefit from surgery and informs medical decisions, potentially avoiding unnecessary surgeries for those unlikely to gain seizure control.

The first total synthesis of liangshanone, a hexacyclic ent-kaurane diterpenoid alkaloid, has been completed. Its intricate cagelike framework was assembled through several key transformations, including an oxidative dearomatization/Diels-Alder (OD/DA) cycloaddition sequence, a tandem alkene cleavage/Mannich cyclization, a Robinson-type annulation, and an intramolecular aldol reaction. Notably, an organocatalytic enantioselective α-hydroxymethylation process allowed the preparation of an enantiomerically enriched tricyclic intermediate that should enable asymmetric access to the target natural product.

In this study, a high-concentration simulated organic wastewater, made by dissolving methyl violet in water, was degraded using dielectric barrier discharge (DBD) plasma generated in air and O respectively. The decoloration rate and chemical oxygen demand (COD) of wastewater were evaluated during plasma treatments with the initial concentration of methyl violet of 300 mg L. Results showed that the highest decoloration rate of around 100% within 10 min and the highest COD decrease of 33% within 60 min could be achieved with the O plasma treatment at the discharge voltage of 10 kV, while air plasma treatment showed lower efficiency in decolorizing the methyl violet solution and lower COD decrease (24%) after 60 min treatment.

Focal cortical dysplasia type II (FCDII) is a cerebral cortex malformation characterized by local cortical structure disorganization, neuronal dysmorphology, and refractory epilepsy. Brain somatic mutations in several genes involved in the PI3K/AKT/mTOR pathway are associated with FCDII, but they are only found in a proportion of patients with FCDII. The genetic causes underlying the development FCDII in other patients remain unclear.
