Squamate ventricular cardiomyocytes: Ploidy, proliferation, and heart muscle cell size in the leopard gecko (Eublepharis macularius)

Developmental Dynamics, EarlyView.
Abstract Background While heart function is broadly conserved across vertebrates, the cellular phenotype of muscle cells (cardiomyocytes) varies across taxa and throughout ontogeny. Emerging evidence suggests that some attributes may correlate with the capacity for spontaneous cardiomyocyte replacement following injury.

Histological investigation of the interthalamic adhesion and periventricular region: Evidence for midline neural connectivity

Ibrain, EarlyView.
This study investigated the interthalamic adhesion histology in human adult South African cadavers, revealing random cytoarchitecture with abundant microglia and widespread neurons observed via Cresyl Violet staining. Findings suggest the interthalamic adhesion may serve as a neural bridge between thalami, offering insights into midline brain ...

Hominin and carnivore roles during the formation of the early Middle Pleistocene site of Loreto (Venosa Basin, southern Italy)

Journal of Quaternary Science, EarlyView.
ABSTRACT The site of Loreto (Venosa Basin, Italy) was first discovered in 1929 and subsequently excavated during the latter half of the 20th century. The excavation revealed three archaeo‐palaeontological levels, with the lowermost level (Level A) yielding the largest number of remains.

Spatial properties of neurons in the monkey striate cortex

Proceedings of the Royal Society of London. Series B. Biological Sciences, 1987
Contrast sensitivity as a function of spatial frequency was determined for 138 neurons in the foveal region of primate striate cortex. The accuracy of three models in describing these functions was assessed by the method of least squares. Models based on difference-of-Gaussians (DOG) functions were shown to be superior to those based on the Gabor ...

Management of Anxiety in Parkinson's Disease

Movement Disorders Clinical Practice, EarlyView.
ABSTRACT Background Anxiety is a common, distressing, hard‐to‐diagnose and hard‐to‐treat symptom in Parkinson's disease. No formal guidelines exist to assist management. Objective We provide a pragmatic guide to detecting and managing anxiety in Parkinson's disease.

Sparse coding in striate and extrastriate visual cortex

Journal of Neurophysiology, 2011
Theoretical studies of mammalian cortex argue that efficient neural codes should be sparse. However, theoretical and experimental studies have used different definitions of the term “sparse” leading to three assumptions about the nature of sparse codes. First, codes that have high lifetime sparseness require few action potentials.

Block‐interleaved segmented echo‐planar imaging for improved activity detection in submillimeter high‐resolution functional MRI at 7 T

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose Isotropic submillimeter high‐resolution functional MRI (fMRI) facilitates noninvasive investigation of neuronal activities at the mesoscale level, including cortical columns and laminae. However, the task‐evoked functional activity becomes less detectable when using single‐shot echo planar imaging (EPI) with parallel imaging techniques

Leaf anatomy of species of Calea sect. Lemmatium (Asteraceae) with a taxonomic emphasis

Nordic Journal of Botany, EarlyView.
Calea sect. Lemmatium is one of five sections of Calea (Neurolaeneae, Asteraceae), containing 12 species that are morphologically similar, which makes their identification difficult to non‐experts. The current study aimed to provide an anatomical characterization of species from Calea sect.

Quality Control Strategies for Differentiation of Kalanchoe Species

Phytochemical Analysis, EarlyView.
ABSTRACT Kalanchoe species products are commercially available in local markets and by internationally accessible online retailers and may exhibit quality issues because of misidentification from similar common names and anatomical similarities among related species used as feedstock. This study proposes an approach using UPLC‐MS/MSE and HPTLC, coupled

Mining Alzheimer's Interactomes, Macromolecular Complexes and Pathways for Drug Discovery

PROTEOMICS, EarlyView.
ABSTRACT Alzheimer's disease (AD) is a progressive neurodegenerative disorder that leads to dementia. Many cases are diagnosed annually and there is no currently available cure. Understanding the underlying disease biology of AD through the study of molecular networks, particularly by mapping clinical variants to tissue‐specific interactomes and ...
