Inhibiting nuclear factor-kappaB (NF-kB) activation in anticancer and antiinflammatory therapy is of topical interest. Current research in molecular biology has dramatically advanced in the understanding of the cellular events involved in NF-kB induction. Dithiocarbamates, in particular diethyldithiocarbamate and pyrrolidinedithiocarbamate, have been known and widely used as strong inhibitors of NF-kB signaling pathway for more than ten years. Their activity is frequently thought to be due to chelating of zinc or copper present in serum supplemented in the culture medium. Zinc(II) diethyldithiocarbamate (Et2Zn) and zinc(II) dibenzyldithiocarbamate (Bz2Zn) were prepared by direct synthesis in aqueous millieu. They were structurally characterized by X-ray... |

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... |

Pentylenetetrazole (PTZ) has recently been found to ameliorate cognitive impairment in rodent models of Down syndrome (DS). The mechanism underlying PTZ’s therapeutic effect is however not clear. Microarray profiling has previously reported differential expression of genes in DS. No mammalian transcriptomic data on PTZ treatment however exists. Nevertheless, a _Drosophila_ model inspired by rodent models of PTZ induced kindling plasticity has recently been described. Microarray profiling has shown PTZ’s downregulatory effect on gene expression in fly heads. In a comparative transcriptomics approach, I have analyzed the available microarray data in order to identify potential mechanism of PTZ action in DS. I find that transcriptomic... |

*Background*
It has been previously reported that most mammalian genes display a circadian oscillation in their baseline expression. Consequently, the phase and amplitude of each component of a signal transduction cascade has downstream consequences. 

*Results*
We report our analysis of alternative transcripts in the leptin signaling pathway which is responsible for the systemic regulation of macronutrient storage and energy balance. We focused on the circadian expression pattern of a critical component of the leptin signaling system, suppressor of cytokine signaling 3 (SOCS3). On an Affymetrix GeneChip 430A2 microarray, this gene is represented by three probe sets targeting different... |

Reports of the beneficial effects of the hypnotic imidazopyridine, zolpidem, described in persistent vegetative state^1, 2^ have been replicated recently in brain-injured and cognitively impaired patients^3-7^. Previous single photon emission computed tomography (SPECT) studies have suggested that sub-sedative doses of zolpidem increased regional cerebral perfusion in affected areas^5, 8^, implying enhanced neuronal metabolic activity; which has led to speculation that zolpidem 'reawakens' functionally dormant cortex. However, a neuronal mechanism by which this hypnotic drug affords benefits to brain injured patients has yet to be demonstrated. Here, we report the action of sub-sedative doses of zolpidem on neuronal network oscillatory... |

Asparagus racemosus Willd., one of the most important medicinal plants, is regarded as a ‘rasayana’ in the Ayurvedic system of medicine and has been recommended for use as a galactagogue, aphrodisiac, anodyne, diuretic and nerve tonic since time immemorial, necessitating its incorporation into a number of important Ayurvedic formulations like Shatavarikalpa, Phalaghrita and Vishnutaila. However, data regarding safety or toxicity of Asparagus racemosus in animal systems is lacking. Hence, the present experiment envisaged acute and sub-acute toxicity of Asparagus racemosus root aqueous extract in adult Charles Foster rats following the guidelines of OECD including parameters like observational, hematological, biochemical and... |

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... |

Women who inherit a defective BRCA1 or BRCA2 gene have risks for breast and ovarian cancer that are so high and seem so selective that many mutation carriers choose to have prophylactic surgery. There has been much conjecture to explain such apparently striking tissue specificity. All these suggestions share the assumption that some disabled function of normal tumor suppressor genes leads to a tissue specific cancer response. Here the idea is proposed and tested that major determinants of where BRCA1/2 hereditary cancers occur are related to tissue specificity of the cancer pathogen, the agent that causes chronic inflammation or the carcinogen. The target tissue may have receptors for the pathogen, become selectively exposed to an inflammatory process... |

In a newly described _Drosophila_ model, two of the five antiepileptic drugs (AEDs) tested, sodium valproate (NaVP) and levetiracetam (LEV), not ethosuximide (ETH), gabapentin (GBP) and vigabatrin (VGB), ameliorate development of chronic pentylenetetrazole (PTZ) induced locomotor alteration. To further characterize the model, we analyze here the microarray expression profile of heads of flies treated with depolarizing compound potassium chloride (KCl). Surprisingly, microarray clustering showed unexpected similarity among KCl, LEV and NaVP. Further, like the two effective AEDs in the fly model, KCl regulated genes overrepresented ribosomal pathway. Interestingly, KCl also ameliorated development of locomotor deficit in the chronic PTZ model. Both... |

Many scientific efforts have been well done to investigate the effects of anti inflammatory agents on the degenerative brain diseases such as Parkinson’s (PD) or Alzheimer’s disease and their affiliated sings. Previously we showed the effectiveness of steroids on rigidity of PD and in the study for further mechanistic investigation of that observation the microdialysis technique was employed to determine the striatal dopamine changes in parkinsonian rats after administration of betamethasone (0.12, 0.24 mg/kg) respectively. Our findings showed us the significant increase in the striatal dopaminergic neurotransmission (P<0.05) after administration of betamethasone comparing to the controls. These observations suggest a new... |

The present study was undertaken to evaluate the antihyperglycemic, antihyperlipidemic and hepatoprotective effect of a traditional unani formulation “Qurs Tabasheer” in streptozotocin (STZ) induced diabetic wistar rats. Up until now, no study was undertaken to appraise the efficacy of “Qurs Tabasheer” in the diabetic rats. Qurs Tabasheer is a unani formulation restraining preparations from six various herbs namely Tukhme Khurfa (Portulaca oleracea seed), Gule Surkh (Rosa damascena flower), Gile armani (Arminium bole), Gulnar (Punica granatum flower), Tabasheer (Bambusa arundinasia dried exudate on node), Tukhme Kahu (Lactuca sativa Linn seed). The effect of Qurs Tabasheer was assessed in STZ (60 mg/kg, i.p... |

Rodent kindling induced by pentylenetetrazole (PTZ) is an established model of epileptogenesis and antiepileptic drug (AED) testing. Recently, a Drosophila systems model has been described in which chronic PTZ causes a decreased climbing speed in adult males on 7th day. Some AEDs ameliorate development of this locomotor deficit. Time-series of microarray expression profiles of heads of flies treated with PTZ has been found to resemble transcriptomic alterations associated with epileptogenesis. In the fly model, withdrawal from seven day long PTZ treatment causes an increased climbing speed on 7th consequent day. Here, we present a systems model of the post-PTZ withdrawal regime. Unlike AED-untreated individuals, flies treated with any of the five AEDs... |

The Ugi reaction has proved to be a convenient way to quickly create diverse libraries of compounds. It involves the reaction of an amine, an aldehyde, a carboxylic acid and an isonitrile typically in methanol at room temperature. The Ugi reaction has often been used as a tool in the synthesis of pharmacologically active molecules. It has been observed that Ugi products sometimes precipitate in pure form from the reaction mixture. This is a very fortunate outcome since the reaction can then be easily scaled up without requiring costly purification procedures such as chromatography. It would be most beneficial to optimize the Ugi product yield as obtained directly from filtering the reaction mixture without further treatment. To this end we utilized a... |

New molecule discovery from natural sources, such as that of actinobacteria, has proved to be an interesting area in antibiotic research, as most of these antibiotics are difficult to synthesize. Out of 30 actinobacterial cultures screened for antimicrobial activity, 28 cultures were found to produce active products against various pathogenic microorganisms such as Gram-negative, Gram-positive bacteria and yeast, using a ‘modified cross streak method.' The modified method helped in easy quantification of results and also in ruling out probable mutual antibiosis. 53%, 13% and 10% of tested actinobacterial strains belonging to Streptomyces, Micromonospora and Actinomadura genera, respectively, showed the ability of producing antimicrobial... |
