Radical-Scavenging and Anti-Oxidative Activities of TBN in Cell-Free System and Murine H9c2 Cardiomyoblast Cells

Abstract:

Reactive oxygen species (ROS) and reactive nitrogen species are believed to be one of the most important culprits in the pathogenesis of cardio/cerebrovascular diseases. Intensive researches have been conducted to target free radicals as potential treatment for cardio/cerebrovascular diseases. The 2-(((1,1-dimethylethyl) oxidoimino)-methyl)-3,5,6-trimethylpyrazine (TBN), a novel nitrone derivative of tetramethylpyrazine, has been demonstrated to exhibit significant therapeutic effects in ischemic stroke and Parkinson’s models due to its multiple functions, including calcium overload blockade and free radical-scavenging activity. In the present study, we found that TBN had significant radical trapping effect in cell-free assays. Additionally, TBN effectively blocked tert-butylhydroperoxide (t-BHP)-induced murine H9c2 cardiomyoblast cell death, suppressed H9c2 cell apoptosis and reversed the decrease in mitochondrial membrane pote...

Clinical and Immunological Beneficial Effects of Phyto V7 Consumption by HIV-1 Seropositive Individuals

Abstract:

Phytochemicals (PHT) are a large group of biologically active plant chemicals that may have positive effects on human health such as immune system stimulation, down regulation of inflammatory responses, radical scavenging activities, cell repair function, and antibacterial and antiviral activity. In this proof of principle 6 months study, the effects of supplementing a PHT mix, Phyto V7, to HIV-1 seropositive individuals and AIDS patients were examined. Individuals with CD4+ T-cells below 350 counts/mm³were assigned to one of the following treatments: CG1 - no treatment, CG2 - only highly active antiretroviral treatment (HAART), TG1 - only Phyto V7, and TG2- both Phyto V7 and HAART. After 3 months of treatment there were approximately (-)1%, 1%, 2% and 4% increase in the mean weight of the CG1, CG2, TG1 and TG2 groups, respectively. The tendency for the body mass index (BMI) was similar. The CD4+ counts increased by 13%, 39%, 53% and 35%, respectively....

Induction of Antioxidant Capacity and Hydroxymethylfurfural Content Variations by Modifications of Cooked Fruit Processing.

Abstract:

Liège syrup is a Belgian traditional cooked fruit foodstuff, produced mainly from apples and pears. The process includes several hours of heating at high temperature during which complex chemical reactions occur, such as Maillard condensation between reducing sugars and amino acids. Aiming at understanding the modifications of the fruit juices during heating, different parameters were monitored throughout the process. It was shown that hydoxymethylfurfural was formed during the first step of concentration by heating. At the end of the process, hydroxymethylfurfural had totally disappeared and the deep brown color of the product suggested that this compound was transformed into melanoidins. A parallel increase in antioxidant capacity was also observed. To determine optimal conditions to reach high melanoidin content and high antioxidant capacity, different in vitro model systems were compared. It was shown that different combinations of an amino a...

Tourette’s Syndrome: Medical, Educational and Behavior Therapy

Abstract:

The French physician, Gill de la Tourette, was the first person to define Tourette’s Syndrome (TS) in 1885 and has brought much attention to it in Western countries for the past few decades. Unfortunately, most Asian countries are not familiar with Tourette’s Syndrome. Tourette’s Syndrome is regarded as a disorder of the nerve system that often appears with involuntary tic behaviors. The purpose of this article is to give a better understanding of Tourette’s Syndrome, starting with a brief background, followed by its pathogenesis and an analysis of treatment, including medication and education. The related studies of Tourette’s syndrome are also discussed in this study.

Reduced Physical Activity Patterns in Patients with Thalassemia Compared to Healthy Controls

Abstract:

Patients with Thal (Thalassemia) are presumed to be inactive for many of the same reasons as healthy adults, though there are limited published data to support this claim. The primary aim of this study was to compare physical activity patterns in subjects with Thal to healthy controls as well as to explore the effects of transfusion therapy on physical activity in transfusion dependent patients with Thal.

Metastatic Malignant Peripheral Nerve Sheath Tumor to the Thyroid

Abstract:

It is extremely rare that sarcomas metastasize to the thyroid. We report a case of a 49 year old male with malignant peripheral nerve sheath tumor (MPNST) metastatic to the thyroid that was diagnosed by ultrasound guided fine needle aspiration (FNA). The FNA cytology showed numerous loosely cohesive pleomorphic small spindle cells, some of which were arranged in short fascicles or haphazard pattern. The nuclei were oval or spindle in shape, with hyperchromatic granular chromatin and inconspicuous nucleoli, and smooth nuclear membrane contours. The cytoplasm was scant to moderate in amount, and delicate. Some cells had long thin cytoplasmic projections. Based on the cytomorphology, a diagnosis of “consistent with metastatic MPNST from small intestine” was rendered and follow-up thyroidectomy confirmed the cytologic diagnosis. Therefore, FNA biopsy is a useful, easy to perform, cost effective, safe procedure that can diagnose secondary tumors of the thyroid, and...

Itraconazole Prophylaxis for an Outbreak of Invasive Aspergillosis in a Hematology Ward after Hospital Construction Work

Abstract:

Hospital construction work, among other environmental factors, is a risk factor for invasive aspergillosis (IA).

Factors Influencing the Effectiveness of a One-day CBT for Insomnia Workshop

Abstract:

Insomnia is highly prevalent and has severe negative consequences. Cognitive Behavioural Therapy for Insomnia (CBT-I) is an evidence-based treatment that is usually delivered individually. Given the high prevalence, accessible one-day CBT-I workshops (each for up to 30 people) were developed to be run in the community for the general public 1. These CBT-I workshops have been found to reduce levels of insomnia 23 and are now run on a routine basis. As yet, little is known about the impact of factors such as co-morbid depression or anxiety, or receipt of previous treatment, on the effectiveness of the CBT-I workshop. This study aimed to evaluate the accessibility and clinical effectiveness of a series of nine one-day CBT-I workshops (n=120) run in routine practice and to explore the impact of factors including co-morbi...
