Morphological Changes in Compressible Foams
We introduce a model free energy, assuming the bubbles in the foam to come in just two sizes and calculate its global minimum for different values of the parameters. We then consider the transition in more detail and show how some subtle factors of the foam's structure and the parameters of the …

Morphological Changes in Alveolar Bone Following Orthodontic Space Closure
<p><em>Introduction: </em>Changes occurring in anterior alveolar bone following orthodontic tooth movement are controversial. Some research has shown that orthodontic tooth movement results in the adaptation of cortical bone; others have shown that it results in dehiscence and fenestrations.</p> …

Experimental investigation of wave-induced morphological changes of gravel beaches
Gravel beaches are widespread around the North-Atlantic Ocean shorelines and can also be found along the coastlines of New Zealand, Russia and the Pacific shore of USA. Over the past decades, researchers in coastal morphodynamics have placed their emphasis on studying sand beaches but gravel …

Grey matter morphological changes in late life using magnetic resonance imaging technique
This PhD thesis examines grey matter (GM) morphological changes in an elderly non‐demented population, and is divided into three broad topic areas. While a few structural MRI studies have examined the relationship between cognitive function and brain morphology using regions of interest …

Ontogenesis of Peptide Transport and Morphological Changes in the Ovine Gastrointestinal Tract
… in all stages of life. As the diet of an animal changes from birth on, morphological and biochemical adaptation can be anticipated in order to accommodate changing demands. The main focus of the present study was to examine the relationship between age and diet on the potential for peptide …

Toxicity, morphological changes, and dissipation of oil sands naphthenic acids in Chlamydomonas reinhardtii
… physiological effects. Exposure to NAFCs induced changes in cell surface protein structure and protein confirmations in WT and CC-400, and altered the diversity and composition of their phospholipid and lipid pools. CC-3395 had minor changes in phospholipid/lipid pools. Exposed WT cells showed …

CBCT Evaluation of Morphological Changes to Alveolar Bone Due to Orthodontic Tooth Movement
… tooth movement. Methods: This study compared changes in area (mm2) and buccal/lingual linear variation of the anterior mandibular process on CBCT images acquired before (T1) and after (T2) orthodontic treatment. Initial (T1) and final (T2) digital imaging and communications in medicine (DICOM) …

Role of ICAM-1, a cell adhesion molecule, in morphological changes of BV2 microglial cell
… one of the major activator of microglia induces morphological changes and activation of the microglial cells. There are a series of cell adhesion molecules (CAM) related with these changes. In our present study, we studied the role of adhesion molecules including Intracellular adhesion molecule-1 …

An analysis of morphological changes in visual cortical neurons after knocking down scaffolding proteins of glutamate receptors
NMDA receptor subunit changes have an important implication in synaptic development, learning, memory, and neuronal disorders. Previous studies have suggested that two membrane-associated guanylate kinase (MAGUK) family scaffolding proteins, SAP102 and PSD-95, are involved in the switch from …

Analysis of the Relationship Between Growth Hormone Receptor Polymorphism rs6180 and Craniofacial Morphological Changes Associated with Herbst Appliance Therapy
… identify mandibular and craniofacial morphologic changes. Changes in Z-scores based on standards from the Michigan Growth Study were then converted to slow or normal growth status by slow being when the Z-score difference between the initial and final measurements is less than zero. The number of …

The effects of magnesium administration on cardiac ventricular function, heart rate variability, and myocardial morphological changes in a chronic diabetes disease model in rats
… on the cardiac histological structure or on the changes in coronary perfusion. Moreover, the overall effects of Mg2+ in diabetes were independent of its effects on the blood glucose level or the alteration of plasma Mg2+ level. Thus, Mg2+ treatment may have long-lasting therapeutic effects on …

The role of tubulin in ganglioside-induced ramifications in cultured rat brain microglia
"In addition to functional changes, activated microglia undergo morphological changes from a resting, ramified morphology to an activated, amoeboid shape. Gangliosides, despite their role as microglial activators, induce microglial ramifications. To identify the cytoskeletal components involved in …

Changes in the Morphology of Hypoglossal Motor Neurons in the Brainstem of Developing Rats
… studies in rodents have demonstrated significant changes in breathing control during the first three weeks of life, with a sensitive period at 10 to 13 days post-birth (P10–P13) characterized by pronounced changes in neurotransmitters, receptors, excitation-inhibition balance, and breathing. …

Comparative analysis of wild and long term captive bred Partula snails using morphometrics and population data
… concern about how this species may be adapting morphologically to their captive environment as they are known to be sensitive to environmental changes. This study focused on ten species of Partula with multiple generations in captivity, which made it possible to compare the morphology of wild to …

Development of Quantitative Optical Coherence Tomography Methods for Cell Death Detection
… induced cancer cell death occurs before changes in tumour volume. Cell death is characterized by a series of predictable and organized subcellular morphological changes. Light scattering theory predicts that changes in the size, shape, number density and spatial organization of …
