Trochopus martydeveneyi n. sp., a large, elegant species is described from the dorsal surface of the pectoral fins of captive Cape gurnard, Chelidonichthys capensis (Cuvier), at Two Oceans Aquarium, Cape Town, originally collected from Table Bay, South Africa in 2007.

Design: Multiple learner algorithms, including penalized regressions, random forests, gradient boosting machine, linear discriminant analysis and bootstrap aggregating decision trees were used. Data were split into training and test datasets. Patient demographics, medical and fertility diagnoses, partner information and geographic locations were analysed.
Article Synopsis
- The study aimed to analyze cognitive and psychological issues in patients at a First Seizure Clinic, hypothesizing that those with epilepsy would show more impairments.
- 201 patients underwent cognitive and psychological screening before their diagnostic assessment, and the results were compared to 35 matched controls.
- Individuals diagnosed with epilepsy experienced the most significant cognitive impairments, especially in learning and memory, while mood issues like depressive symptoms were common across all patient groups, highlighting the importance of early detection.
Article Synopsis
- After a first seizure, anti-seizure medications (ASMs) can influence the likelihood of additional seizures, leading to a study that analyzes brain network changes using fMRI data from 28 participants before and during ASM therapy.
- The research found that ASM treatment increased the clustering coefficient and decreased network path length, indicating more efficient brain connections, with the greatest changes observed in specific brain regions linked to seizure activity.
- The findings suggest that individuals with recurrent seizures exhibit more significant network changes after ASM treatment, highlighting the need for larger studies to better understand the relationship between ASM effects and long-term seizure outcomes.
Article Synopsis
- Vascular epiphytes in tropical montane cloud forests are at risk due to climate change, as rising cloud bases limit moisture and atmospheric inputs, particularly for those growing on isolated pasture trees.
- Researchers studied the water relations of these epiphytes in Monteverde, Costa Rica, measuring sap velocity and microclimate variables across different seasons and sites.
- Results showed that drought conditions increased the turgor loss point of the epiphytes, with significant correlations between microclimate and sap velocity in the wet season, highlighting potential vulnerabilities in pasture trees compared to those in the forest.
