Reduction of fibromyalgia symptoms through intravenous nutrient therapy: results of a pilot clinical trial.

Objective: To evaluate the effectiveness of a modified Myers' formula of intravenous nutrient therapy (IVNT) on the symptoms of fibromyalgia (FM) in therapy-resistant FM patients.

Methods: In this pilot clinical trial, 7 participants with therapy resistant FM were given IVNT once per week for 8 weeks. Patient's pain levels, fatigue, and activities of daily living were evaluated weekly.

Long-term depression: multiple forms and implications for brain function.

Long-term potentiation (LTP) and long-term depression (LTD) remain widely accepted vertebrate models for the cellular and molecular mechanisms that underlie synaptic changes during learning and memory. Although LTD is a phenomenon that occurs in many regions of the CNS, it is clear that the mechanisms recruited in its induction and expression can vary, depending on many factors, including brain region and developmental time point. LTD in the hippocampus and cerebellum is probably the best characterized, although there are also other brain areas where mechanisms of LTD are well understood, and where it is thought to have a functional role.

Pandemic planning at the coal face: responsibilities of the public health unit.

Responding to an infectious disease pandemic requires a coordinated approach from all essential services. Public health units across NSW will play an important role in a range of control activities. These include: surveillance, education, communication, case ascertainment, case management (excluding clinical management), infection control, contact tracing, monitoring contacts in home quarantine, surveillance at borders, epidemiological studies and immunisation.

Intravenous nutrient therapy eliminated androgen deprivation therapy-induced hot flashes in two men with prostate cancer.

Androgen deprivation therapy (ADT) is commonly used for the treatment of prostate cancer. For many undergoing ADT, hot flashes can affect and significantly reduce quality of life. Traditional medications for hot flashes are limited by both clinical effectiveness and side effects.

Impact of sentinel lymph node biopsy on the evolution of breast reconstruction.

Background: Although sentinel lymph node biopsy is rapidly replacing complete axillary lymph node dissection for lymph node staging in women with clinically node-negative breast cancer, it is unclear what impact the transition to sentinel lymph node biopsy will have on the practice of breast reconstruction.

Methods: To determine the effect of the transition from complete axillary lymph node dissection to sentinel lymph node biopsy on their practice of breast reconstruction, the authors reviewed the records of 717 patients with breast cancer who underwent sentinel lymph node biopsy and 1887 breast reconstructions-487 were performed in patients who also underwent sentinel lymph node biopsy at The University of Texas M. D.

Differential roles of NR2A and NR2B-containing NMDA receptors in LTP and LTD in the CA1 region of two-week old rat hippocampus.

The role of NMDA receptors in the induction of long-term potentiation (LTP) and long-term depression (LTD) is well established but which particular NR2 subunits are involved in these plasticity processes is still a matter of controversy. We have studied the effects of subtype selective NMDA receptor antagonists on LTP induced by high frequency stimulation (100 Hz for 1s) and LTD induced by low frequency stimulation (1 Hz for 15 min) in the CA1 region of hippocampal slices from 14 day old Wistar rats. Against recombinant receptors in HEK293 cells NVP-AAM077 (NVP) was approximately 14-fold selective for NR2A vs NR2B receptors, whilst Ro 25-6981 (Ro) was highly selective for NR2B receptors.

Randomized pilot test of a lifestyle physical activity intervention for breast cancer survivors.

Objective: This paper will report the results of a pilot test of a 6-month, 21-session intervention to increase breast cancer survivors' physical activity by teaching them to incorporate short periods of moderate activity into their daily routines (lifestyle intervention). The effect of the intervention on physical performance, quality of life, and physical activity are reported.

Methods: Sixty breast cancer survivors were randomized to either a lifestyle intervention or a standard care control group.

Steroid myopathy in patients with acute graft-versus-host disease treated with high-dose steroid therapy.

High-dose steroids are the first line of treatment for acute graft-versus-host disease (aGVHD). Steroid myopathy is a debilitating steroid-induced complication that significantly impairs a patient's performance status. To determine the frequency and severity of steroid myopathy and other steroid related complications in patients with acute myeloid leukemia (AML)/myelodysplastic syndrome (MDS) who developed grade >or=2 aGVHD after allogeneic hematopoietic stem cell transplantation (HSCT), we performed a retrospective analysis.

Human-competitive evolution of quantum computing artefacts by Genetic Programming.

We show how Genetic Programming (GP) can be used to evolve useful quantum computing artefacts of increasing sophistication and usefulness: firstly specific quantum circuits, then quantum programs, and finally system-independent quantum algorithms. We conclude the paper by presenting a human-competitive Quantum Fourier Transform (QFT) algorithm evolved by GP.

Active for Life After Cancer: a randomized trial examining a lifestyle physical activity program for prostate cancer patients.

Background: Active for Life After Cancer is a randomized trial evaluating the efficacy of a 6-month group-based lifestyle physical activity program (Lifestyle) for prostate cancer patients to improve quality of life (QOL) including physical and emotional functioning compared to a group-based Educational Support Program and a Standard Care Program (no group).

Method: A total of 134 prostate cancer patients receiving continuous androgen-ablation were randomly assigned to one of the three study conditions.

Results: Results indicated no significant improvements in QOL at 6 or 12 months.

Experience-dependent modification of mechanisms of long-term depression.

Mechanisms of long-term potentiation and depression (LTP and LTD) change considerably during development, but the importance of these changes and the factors that control them is not clear. We found that visual experience triggered a switch in mechanisms of LTD in rat perirhinal cortex, an area critical for visual recognition memory. Thus, changes in synaptic plasticity mechanisms were correlated with the changing physiological demands on the CNS.

cAMP responsive element-binding protein phosphorylation is necessary for perirhinal long-term potentiation and recognition memory.

We established the importance of phosphorylation of cAMP responsive element-binding protein (CREB) to both the familiarity discrimination component of long-term recognition memory and plasticity within the perirhinal cortex of the temporal lobe. Adenoviral transduction of perirhinal cortex (and adjacent visual association cortex) with a dominant-negative inhibitor of CREB impaired the preferential exploration of novel over familiar objects at a long (24 h) but not a short (15 min) delay, disrupted the normal reduced activation of perirhinal neurons to familiar compared with novel pictures, and impaired long-term potentiation of synaptic transmission in perirhinal slices. The consistency of these effects across the behavioral, systems, and cellular levels of analysis provides strong evidence for involvement of CREB phosphorylation in synaptic plastic processes within perirhinal cortex necessary for long-term recognition memory.

Differential roles of NR2A and NR2B-containing NMDA receptors in cortical long-term potentiation and long-term depression.

It is widely believed that long-term depression (LTD) and its counterpart, long-term potentiation (LTP), involve mechanisms that are crucial for learning and memory. However, LTD is difficult to induce in adult cortex for reasons that are not known. Here we show that LTD can be readily induced in adult cortex by the activation of NMDA receptors (NMDARs), after inhibition of glutamate uptake.

Improved vascular gene transfer with a helper-dependent adenoviral vector.

Background: Adenoviral vectors are the most widely used agents for vascular gene transfer. However, the utility of adenoviral vectors for vascular gene transfer is limited by brevity of expression and by the induction of a significant host inflammatory response. Third-generation or "helper-dependent" adenoviral vectors have achieved prolonged recombinant gene expression in liver and muscle with minimal associated inflammation; however, they have never been tested for vascular gene transfer.

Cholinergic neurotransmission is essential for perirhinal cortical plasticity and recognition memory.

We establish the importance of cholinergic neurotransmission to both recognition memory and plasticity within the perirhinal cortex of the temporal lobe. The muscarinic receptor antagonist scopolamine impaired the preferential exploration of novel over familiar objects, disrupted the normal reduced activation of perirhinal neurones to familiar compared to novel pictures, and blocked production of long-term depression (LTD) but not long-term potentiation (LTP) of synaptic transmission in perirhinal slices. The consistency of these effects across the behavioral, systems, and cellular levels of analysis provides strong evidence for the involvement of cholinergic mechanisms in synaptic plastic processes within perirhinal cortex that are necessary for recognition memory.

Galanin regulates spatial memory but not visual recognition memory or synaptic plasticity in perirhinal cortex.

It has previously been shown that the neuropeptide galanin plays a role in the age-dependent regulation of hippocampal synaptic plasticity and spatial memory. Here, we further extend these studies by demonstrating that galanin knockout mice also have deficits in an object-in-place spatial memory task. In contrast however, there is no deficit in single item object recognition memory, a memory that depends on perirhinal cortex.

Chronic suppression of insulin by diazoxide alters the activities of key enzymes regulating hepatic gluconeogenesis in Zucker rats.

Objectives: Chronic attenuation of hyperinsulinemia by diazoxide (DZ), an inhibitor of glucose-mediated insulin secretion, improved insulin sensitivity and glucose tolerance and caused down-regulation of lipid metabolizing enzymes in adipose tissue and decreased the rate of weight gain in mildly hyperglycemic obese Zucker rats. Since the liver plays a central role in glucose homeostasis, we studied the effect of chronic insulin suppression on key insulin-sensitive enzymes regulating hepatic gluconeogenesis.

Methods: DZ (150 mg/kg per day) or vehicle (control) was administered to 7-week-old female obese and lean Zucker rats for a period of 4 weeks.

Dietary supplements.

The amount of published information on dietary supplements mushroomed in the 1990s. In fewer than 5 years, publications increased at least 100-fold in the medical literature alone. Dietary supplements are an uncharted territory that warrants complete and accurate exploration.

Activation of muscarinic receptors induces protein synthesis-dependent long-lasting depression in the perirhinal cortex.

There is strong evidence that decrements in neuronal activation in perirhinal cortex when a novel stimulus is repeated provide a neural substrate of visual recognition memory. There is also strong evidence that muscarinic acetylcholine (ACh) receptors are involved in learning and memory. However, the mechanisms underlying neuronal decrements in the perirhinal cortex and the basis of ACh involvement in learning and memory are not understood.

A single case report of healing through specific martial art therapy: comparison of MRI to clinical resolution in severe cervical stenosis: a case report.

Objectives: A 76-year-old patient with chronic and severe spinal cord compression secondary to cervical stenosis, a cervical osteophyte, and a herniated intervertebral cervical disk had lasting resolution of symptoms after completing a specific, martial art-based, physical therapy program. We wanted to determine if there were structural changes in the cervical spine that could account for the prompt resolution of symptoms.

Design: A 76-year-old female completed 8 weeks of a specific, martial art-based, physical therapy.
