Epidermis and Re-epithelialization in <i>Schmidtea mediterranea</i>
… its ability to close the wound is essential for tissue recovery. Planarian epidermis enables animal recovery and survival after virtually any body part amputation. Nevertheless, neither the epidermis nor the mechanisms endowing such a remarkable wound healing capacity is described in detail in …

Ecosystem Reboot : How scientists are building an inside-out Noah’s Ark for Florida’s vanished coral reefs
… a deadly marine plague called stony coral tissue loss disease has inspired an unprecedented conservation plan: to rescue affected corals from the wild, and keep them alive in captivity, indefinitely. The idea was to make a Noah’s Ark turned inside out, evacuating corals from an inhospitable …

Naturally Derived Scaffolds for Treatment of Volumetric Muscle Loss
Volumetric muscle loss (VML) is defined as the irrecoverable loss of function in skeletal muscle as a result of tissue loss. Herein, cell and growth factor loaded keratin hydrogels and Tissue Engineered Muscle Repair (TEMR) constructs consisting of cell seeded, cyclic stretched bladder acellular …

Audit of acute limb ischaemia in a paediatric intensive care unit
… 8.7% poor and in 21.7% no responses. Documented tissue loss related to the ischaemia occurred in six (21.4%) of the 28 patients. Conclusions: Iatrogenic acute limb ischaemia in children are usually managed without surgical intervention. Pharmacological sympathectomies lead to increased blood flow …

Examining coral reef ecosystem dynamics using microorganisms and metabolites
… to corals afflicted with the lethal stony coral tissue loss disease and identified specific microorganisms which were biological indicators of the disease. In Chapter 3, I investigated the dynamics of microorganisms over short temporal tidal and diurnal cycles, as well as spatially across US …

Age-Dependent Effects Of Chronic GABAA Receptor Blockade In Barrel Cortex
… of GABAA receptors resulted in substantial tissue loss and neuron loss. The greater loss of neurons in young rats supports the hypothesis that a high density of GABAA receptors protects neurons from excessive excitatory input during a sensitive period in development.

Femoro-distal bypass surgery at Groote Schuur Hospital: a 4-year retrospective study
… presentation, these patients frequently exhibit tissue loss, gangrene, ischemic ulceration and forefoot infection. Critical limb ischemia represents the end stage of lower limb atherosclerotic disease, and multi-segmented arterial occlusion is the rule on angiogram.

Assessment of in vitro engineered microvascular networks and their application in the treatment of chronic wounds
As the number of individuals suffering from tissue loss and end-stage organ failure continues to grow, researchers are turning to tissue engineering to provide better methods of treatment. The field, however, still faces many technical challenges that are limiting its applications. One challenge …

Injectable chemokine-releasing gelatin matrices for enhancing endogenous regenerative responses in the injured rat brain
… worldwide each year and often cause irreversible loss of neural tissue that disrupts vital neurological functions. Cell transplantation has traditionally been the strategy for achieving neuroregeneration but endogenous regenerative responses such as neurogenesis and neovascularization are …

Metabolic profile and post-operative outcomes in contemporary patients with peripheral arterial disease and critical limb ischaemia
… (23.3%) had rest pain and 56 (76.7%) had tissue loss [Minor tissue loss was 47 (64.4%) and major tissue loss was 9 (12.3%)]. Current smokers and previous smokers constituted 86% of the sample population with a male to female ratio of approximately 1:1. Our study population was generally …

A self-powered single-chip wireless sensor platform
… frequencies within the window for minimum tissue loss and bio-compatibility This thesis describes a low power and low-cost internet of things system suitable for implant applications that is implemented in its entirety on a single standard CMOS chip with an area smaller than 0.5 mm2. The …

EFFECTS OF HYPERTONIC SALINE ON RECOVERY OF FUNCTION FOLLOWING CONTROLLED CORTICAL IMPACT BRAIN INJURY
… animals lost significantly more cortical tissue than either the NAM or Vehicle-treated animals. HS-treated animals showed a greater loss of hippocampal tissue compared to the other groups. In general, NAM showed a faster rate of recovery than HS without this associated tissue loss. Study 1 …

Neuropsychological Functioning and Regional Cerebral Blood Flow: A Comparison Between Aged Normals and Alzheimer’s Type Dementia.
… agreement on focal areas of functional brain tissue loss. Nine subjects with Alzheimer’s disease were compared to nine normal subjects who had been matched on the basis of age, sex, race, and education. Discriminant analysis revealed 100% correct classification of all patients and normals …

Foraging Ecology of Parrotfishes in the Greater Caribbean: Impacts of Specialization and Dietary Preferences on Marine Benthic Communities
… acute and generally associated with the loss of key herbivores and an increase in algae. Herbivorous fishes such as parrotfishes can positively impact coral reefs by removing algae that compete with corals for light and space. However, many parrotfishes are also important coral predators. …

THE ROLE OF INNERVATION IN ENGINEERED MUSCLE
… deficits each year, including volumetric muscle loss (VML) resulting from ballistic trauma, blast injury, surgical resection, and accidental damage. Such injuries are not restricted to any specific age group and often lead to long-term or permanent reductions in mobility, physical strength, and …

Nutrient sensing by the mTORC1 pathway in physiology
… Sestrin1 and Sestrin2 fail to inhibit mTORC1 in tissues when deprived of dietary leucine. These mice suffer from severe loss of white adipose tissue and skeletal muscle when deprived of leucine, but not other essential amino acids. We showed that their white adipose tissue loss results from …

Biochemical changes associated with embryonic and larval development in the American lobster Homarus americanus Milne Edwards
… which could be catabolized without concomitant tissue loss. P. ethanolamine and sterols were primarily associated with cellular membranes. During tissue catabolism (starvation), P. ethanolamine was catabolized but sterol was conserved. On average, P. ethanolamine fatty acids were the most …

Characterization and Fabrication of Scaffold Materials for Tissue Engineering
Tissue loss and end-stage organ failure has been a significant health challenge for millions of Americans, with the total national health cost exceeding $400 billion per year. Tissue engineering aims to address this challenge. During the process of tissue engineering, scaffolds and matrices are …
