| Commercially available medicinal plant extracts such as Ginkgo biloba leaf extract show no consistent pattern of clinical benefit for people with dementia or cognitive impairment, and have been suggested to be toxic to cells at higher doses. However, medicinal plants may contain other more efficient bioactive molecules apart from the well-known flavonoids and terpenoids. Therapeutic recombinant plant-made copper chaperone for superoxide dismutase (CCS) derived from Ginkgo biloba leaves may establish and maintain physiologic Cu levels through restoration and modulation of biometal metabolism in organ systems of younger Alzheimer patients (> 50 years). Medications developed from plant-made copper chaperone proteins may delay progression during early... |

Medications developed from plant-made copper chaperone proteins may delay progression during early disease stages or even be a basis for a possible causal treatment of preclinical stages of Alzheimer’s disease by restoring cellular function of the CCS-SOD-1 mechanism and by preventing formation of Aβ plaques, a major putative factor involved in Alzheimer’s disease pathogenesis. |

| Age has long been known as the primary population 'risk factor' for cancer. We suggest that the observed disparities in hormonal cancers by ethnicity, gender, and other indices of social structure and power relationships, imply a differential aging by psychosocial and environmental exposures, in the context of cross-generational epigenetic heritage. A relatively simple model of malignancy regulation illuminates the cellular root of induced aging, and explains the decline in cancer rate with extreme old age via telomere shortening. We find that the multifactorial determinants of the disorder cannot be effectively addressed by 'small molecule' interventions at the individual level, but must involve comprehensive prevention... |

| Terpenoids, traditionally used for cosmetic and medicinal purposes, are currently being explored as cancer chemopreventive as well as chemotherapeutic agent in clinical trials. α-(-)-bisabolol, a naturally occurring monocyclic sesquiterpene alcohol is a major component of essential oil of chamomile (Matricaria recutita L., Chamomilla recutita L., Matricaria chamomilla; Family Asteraceae). As substantiated previously, α-(-)-bisabolol is known to have antimicrobial, anti-irritant, anti-inflammatory and anti-allergic properties. It also affects cell viability and growth of various human and murine cell lines by either inducing apoptosis or suppressing Akt activation or down regulating expression of some genes implicated in carcinogenesis.... |

| A critical overview of recent clinical trials in cancer is presented focused on signaling pathways blockers or inhibitors with a view to developing successful clinical trials employing personalized cancer therapies. Rational, pharmacogenomic strategies in cancer trials should be adopted that include specific molecular targeting based on adequate data for, and detailed modeling of, cancer cell genomes, modifications of cancer signaling pathways and epigenetic mechanisms. Novel translational oncogenomics research is rapidly expanding through the application of highly sensitive and specific advanced technology, research findings and computational tools and complex models to both pharmaceutical and clinical problems. Multiple sample analyses from several... |

| Within 24 hrs after injecting botulinum neurotoxin A (BoNT/A) into the hindlimb, mice lost the toe spread reflex and developed progressive muscle weakness. At the same time, the compound muscle action potential amplitude decreased. Injection of capsaicin before BoNT/A significantly reduced these affects and protected the muscle twitch tension of the Extensor digitorum longus (EDL) nerve muscle preparation. Acute in vitro exposure of isolated nerve muscle preparations, as well as Neuro 2a cells, to capsaicin prevented uptake of Alexa 647 BoNT/A. Motor nerve endings as well as Neuro 2a cells express the capsaicin receptor, a transient receptor potential channel of the vanilloid family (TRPV1). Capsaicin as well as disruption of clathrin coated pits (CCPs)... |

| Background: There exists a sub group of patients with uremic cardiomyopathy who experience resolution of heart failure following hemodialysis. It has been hypothesized that these patients are fluid overloaded, and following hemodialysis, show improvements in cardiac geometry and function. We wanted to study their clinical, biochemical and echocardiographic features to define any other additional characteristics.

Aim: To define characteristics of reversible systolic dysfunction.

Methods: We studied 72 patients with chronic kidney disease on hemodialysis of whom 52 presented with congestive heart failure, over a period of 190 days. We studied their echocardiographic profile and blood... |

| Assessing the relative reward value of cocaine and how it changes with repeated use represents a long-standing goal in addiction research. Surprisingly, recent experimental research in rats – the most frequently used animal model in the field – suggests that the reward value of cocaine may in fact be relatively weak at least in the majority of individuals. Here, we provide strong additional evidence that confirms and extends the validity and generality of this research. Specifically, we demonstrate that no matter how heavy is past cocaine self-administration, most rats value cocaine poorly and readily decide to quit when offered the opportunity of making a different choice (i.e., drinking water sweetened with saccharin, an otherwise... |

| Fenugreek (Trigonella foenum- graecum) is both herb (leaves) and a spice (seed) belonging to the family Fabaceae. Fenugreek leaves and seeds are used in the cuisine of India. Fenugreek also has medicinal value. Fenugreek seeds are known to reduce serum glucose and improve glucose tolerance and hence are prescribed to diabetic patients. In the recent past supplemental Chromium is being prescribed to diabetic patients to activate (increased- insulin binding, insulin receptor number, insulin receptor phosphorylation) insulin. Plants can uptake substantial quantities of toxic metals from contaminated soils if these soils are well ameliorated. 

It is then probable that the medicinal efficacy of Fenugreek in the case of... |

| _Chromobacterium violaceum_ is an opportunistic human pathogen causing a range of gastric infections and occasionally septicemia. This Gram-negative bacillus is a common inhabitant of soil and water in tropical and subtropical areas of the world. Infection occurs after contamination of damaged skin exposed to soil or environmental water. Alternatively, systemic infection can follow the aspiration or ingestion of contaminated water. The major features of infections by _C. violaceum_ are, in generally, rapid clinical course, multiple visceral abscesses, and high mortality. Genomic data on the type strain ATCC 12472 has provided a comprehensive basis for detailed studies of pathogenicity, virulence and drug resistance genes. In this study, the susceptibility... |

| Cocaine inhibits high-affinity neurotransmitter uptake at the presynaptic nerve terminals to increase synaptic levels of dopamine, norepinephrine and serotonin^1^. This increase of synaptic dopamine may cause neurotoxicity^2,3^. At least two different mechanisms have been proposed for the development of dopamine-related neurotoxicity: 1) dopamine produces a free radical that may induce cell toxicity^2,3^ and 2) dopamine reduces glutamate transport at its presynaptic sites to increase synaptic levels of this amino acid^4^ and augments glutamate transmission by activating dopamine D1 receptors in different areas of the brain^5-7^. Increase in glutamatergic transmission mediated by the activation on N-methyl dextro-aspartate (NMDA) receptors has been shown to... |
