Hyperbaric Oxygen Therapy Improves Cognition in Patients Severe TBI; A Prospective Study

Cognitive impairment post TBI is an important factor in rehabilitation outcomes. Pharmacological and therapeutic services do not directly address damage to the cortical infrastructure. Hyperbaric Oxygen Therapy is known to improve brain function and healing.

Computer Simulations of Brain Oxygenation at the Microvascular Level Validating a New Role of the Arterioles

Brain physiology critically depends on constant oxygen supply to the neurons to ensure various energy–dependent functions of the central nervous system. A volume of latest experimental data on oxygen metabolism obtained with high temporal and spatial resolution, with both invasive and non-invasive methods, and the use of technologies of various degrees of sophistication, strongly suggests arteriole involvement in brain oxygenation. This new approach challenges the traditional views on brain oxygenation according to which oxygen supply to the brain tissues occurs by diffusion at the capillary level.

Computer Modeling of Convective Mass Transfer of Glucose, Oxygen and Carbon Dioxide in the Neurovascular Unit

Glucose and oxygen are obligatory energy substrates for the brain and their continuous supply to the neurons, as well as the elimination of the end product – carbon dioxide, is of paramount importance for brain physiology and survival. Transport of these substrates from the brain capillaries to the neurons presents a challenging issue.

Oxygen Balance Homeostasis and Tissue Metabolic Score (TMS) of Patients in Emergency and Critical Care Medicine

Patients admitted to the emergency room or intensive care units (ICUs) need real-time monitoring of body oxygen balance. As of today, the availability of monitoring devices that provide real-time data on tissue level of oxygen homeostasis is very limited. The involvement of mitochondrial dysfunction in many pathological states such as stroke, sepsis or heart failure is calling for a real-time evaluation of this intracellular organelle. In order to avoid the deterioration of the most vital organs in the body (brain and heart), we are proposing to monitor a less vital organ, such as the urethral wall, that serves as an early warning signal for the deterioration of body oxygen balance.

Macrocystis of the Lung in a Preterm Neonate: Case Report

Thoracic ultrasonography has been used to evaluate pulmonary parenchyma and the macrocystis of the lung in a preterm with congenital cystic adenomatoid malformation type I. The images gained have been important for diagnosis and therapeutic strategies in our case. An infant was prematurely born with congenital cystic adenomatoid malformation type I. The chest X-ray and computerized tomography showed a great opaque area in the entire right lung, we considered performing a pneumonectomy. This opaque area hampered the expansion of left lung. After draining the macrocystis by ultrasonography-guided puncture, it was possible considering and performing the lobectomy due to the reduction of the volume of macrocystis. During follow up at 4 months, the infant did not show complications and the chest X-ray revealed the reduction of volume of the dense area in parenchyma of right lung.

Intramural Abscesses: A Sequela of Infective Endocarditis in a Patient with HIV

Infective Endocarditis (IE) is associated with significant morbidity and mortality, with in-hospital mortality having been reported as ranging from 19-26%. Commonly documented complications of IE include valvular and chordae destruction and resultant regurgitations, embolic events, peri-valvular abscesses, fistulae, and congestive heart failure.

Mitochondrial Actions for Fat Browning and Energy Expenditure in White Adipose Tissue

White adipose tissue (WAT) is an endocrine organ with crucial role in the development of obesity and related diseases. White adipocytes have less mitochondria than brown adipocytes; nevertheless, there is an increasing body of evidence showing that mitochondrial parameters play a relevant role in WAT physiology, such as proliferation, differentiation and triacylglycerol storage levels.

Mesenchymal Stem Cells from Different Tissues: Immune Status and Activity

Mesenchymal stem cells (MSCs) have been found in almost all tissues and due to their regenerative properties represent promising tools in cell-based therapy. Role of MSCs in tissue repair is strongly governed by their interplay with immune cells and regulating factors.

The Role of Nutrition in Fighting Free Radicals

This paper aims to review in literature the main mechanisms of oxidative stress, pointing out the major formed metabolites, the mechanisms of cell damage and major antioxidants. Oxygen is essential to human life. The formation of free radicals (FR) is closely related to oxygen consumption, a mechanism that occurs with an incomplete reduction of this molecule.

A New Bi-Functional Derivative of Polyethylene Glycol as Molecular Carrier for Eugenol and Ibuprofen

Eugenol (EU) and ibuprofene (IBU) were covalently bound to a bi-functionalized PEG, used as molecular carrier of drugs and the release kinetics of the two bioactive molecules was studied in vitro in buffer solution at pH 7.4, in simulated gastric fluid and in mouse plasma.

Toxic Effect of Titanium (Tio2) on Wistar Rat (Rattus Norvegicus) Injected by Intravenously

Titanium dioxide (TiO2) (<100 nm) has been widely used in the production of paints, paper, and plastics, as well as in food additives and colorants .It has been classified as biologically inert in both humans and animals. Here we studied the toxicity of TiO2 on Wister rat. Main exposure area of NPs is caudal vein of Wistar rat.

Penetrating Arrow Wound of the Chest - A Case Report

In ancient India arrow injury was prevalent as it was a one of the most frequently used weapon. With passage of time use of bow and arrow became restricted to tribal area and its use became limited mostly to hunting. But in the recent years with progressively increasing terrorist activity in some areas arrow injuries are becoming more and more frequent.

Complex Traumatic Facial Degloving Injury

By definition, degloving is detachment of skin and subcutaneous tissue, most often affecting the limbs and extremities and occasionally the scalp. Degloving generally occurs from high-energy trauma. This paper describes an extreme case of traumatic facial degloving injury. This is an extremely rare condition, as the patient survived despite the risk of imminent death. This case report addresses the decisions made regarding the emergency management, prevention of necrosis and infection by surgical debridement and timely repair of the vital soft tissue structures that guided the management.
