Angiogenesis is a crucial component of lung pathophysiology, not only in cancer but also in other disorders, such as chronic obstructive pulmonary disease (COPD). In COPD angiogenesis is definitely able to control and orchestrate the progression of airway remodeling. Herein, we provide several remarkable translational aspects of angiogenesis in COPD, exploring both basic and clinical research in this field. Indeed, we present a number of pro- and anti-angiogenic factors, which can be also used as potential biomarkers to monitor disease progression.

Cancer, one of the leading causes of death worldwide, is an abnormal cell proliferation that fails to respond to the normal signals. In an effort to eradicate the growing menace of cancer, a clear understanding of fundamental biology and molecular mechanism of carcinogenesis is essential for targeted therapies. Among the devised strategies in use for cancer treatment, the one that is of immense interest is the development of plant based novel anticancer agents. Due to their tremendous availability, biological activity and efficacy, the phytochemicals deemed a gibbous future in chemoprevention. In the present study, several phenolics based structurally related compounds of steroidal and non-steroidal skeleton were synthesized and tested for their... |

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... |

Contradictory results have been reported regarding the anti-viral activity of (E)-cinnamaldehyde, a major constituent (~69%) of cinnamon. Here we show that (E)-cinnamaldehyde alone has very low antiviral property contrary to the belief of commoners. There are early sporadic reports in ancient medicinal practices that fine sand was used for increasing the efficacy of antiviral drugs. Can we increase the efficacy of (E)-cinnamaldehyde marginally by using one of the major constituents of sand like silica? Yes, when nanosilica is used as a carrier during (E)-cinnamaldehyde administration, the antiviral efficacy of the resultant cocktail increases marginally. Therefore, (E)-cinnamaldehyde consumed for centuries in tribal therapy as well as in alternative... |

Pain initiated or caused by a primary lesion or dysfunction in the nervous system is defined as neuropathic pain. It results from direct injury to nerves in the peripheral or central nervous system and is associated with several clinical symptoms. Neuropathic pain treatment is extremely difficult, as it is a very complex disease, involving several molecular pathways. Excitatory or inhibitory pathways controlling neuropathic pain development show altered gene expression, caused by peripheral nerve injury.
This study used several experimental pain models to demonstrate the occurrence of programmed cell death in the centers controlling pain induction and maintenance, such as spinal cord and pre-frontal cortex. We combined behavioural,... |

Chemical imaging is a technique for the simultaneous measurement of spectra (chemical information) and images or pictures (spatial information)^1,2^. The technique is most often applied to either solid or gel samples, and has applications in chemistry, biology^3-8^, medicine^9,10^, pharmacy^11^ (see also for example: Chemical Imaging Without Dyeing), food science, Food Physical Chemistry, Biotechnology^12,13^, Agriculture and industry. NIR, IR and Raman chemical imaging is also referred to as hyperspectral, spectroscopic, spectral or multi-spectral imaging (also see micro-spectroscopy). However, other ultra-sensitive and selective, chemical imaging techniques are also in use that involve either UV-visible or fluorescence microspectroscopy. |

The Crown gall tumour assay (CGTA) is one of several bench top bioassays recommended for the rapid screening of plants with anti-cancer activity. The rationale for the use of the bioassay is that the tumorogenic mechanism initiated in plant tissues by _Agrobacterium tumefaciens_ is in many ways similar to that of animals. Several plant species with anti-cancer activity have already been discovered using this bioassay. However till date no explicit test of an association between anti-cancer activity of plants and their resistance to crown gall formation has been demonstrated. Demonstration of an association could have exploratory potential when searching for plants with anti-cancer activity. In this paper, we determined whether or not a statistically... |

OBJECTIVES: This study was designed to simulate standard and optimized dosing regimens for intravenous antibiotics against contemporary populations of Escherichia coli, Klebsiella pneumoniae, Acinetobacter baumannii, and Pseudomonas aeruginosa using MIC distribution data to determine which of the tested carbapenem regimens provided the greatest opportunity for obtaining maximal pharmacodynamic (PD) activity. METHODS: The isolates studied were obtained from the COMPACT-COLOMBIA surveillance program conducted between February and November 2009. Antimicrobial susceptibility testing was conducted by broth microdilution method according to the CLSI guidelines. Doripenem, imipenem-cilastatin, and meropenem, were the modeled antibiotics. A 5,000 patient Monte... |

Changes in the molecular topology of glycan/lectin interaction may explain observed reaction punctuation driven by experimental gradients in reactant concentration. Adoption of a 'biological renormalization' perspective from statistical physics for the analysis of such phase transitions suggests, in marked contrast to conventional physical systems, a broad spectrum of possible universality class behaviors. This spectrum may, in typical perverse biological manner, be of central scientific interest. Generalization, via formalism abducted from coevolutionary theory, suggests that glycan/lectin molecular switches instantiate logic gates that may be as sophisticated as those characterizing basic neural process, if on a different scale. |

Sumac is the common name for a genus (Rhus) that contains over 250 individual species of flowering plants in the family Anacardiaceae. These plants are found in temperate and tropical regions worldwide, often grow in areas of marginal agricultural capacity, and have a long history of use by indigenous peoples for medicinal and other uses. The research efforts on sumac extracts to date indicate a promising potential for this plant family to provide renewable bioproducts with the following reported desirable bioactivities: antifibrogenic, antifungal, antiinflammatory, antimalarial, antimicrobial, antimutagenic, antioxidant, antithrombin, antitumorigenic, antiviral, cytotoxic, hypoglycaemic, and leukopenic. As well, the bioactive components can be extracted... |

The discovery of secondary metabolites produced by microorganisms (e.g., penicillin in 1928) and the beginning of their industrial application (1940) opened new doors to what has been the main medication source for the treatment of infectious diseases and tumors. In fact, approximately 80 years after the discovery of the first antibiotic compound, and despite all of the warnings about the failure of the "goose that laid the golden egg," the potential of this wealth is still inexorable: simply adjust the focus from "micro" to "nano", that means changing the look from microorganisms to nanograms of DNA. Then, the search for new drugs, driven by genetic engineering combined with metagenomic strategies, shows us a way to bypass the barriers imposed by... |

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 proteins, 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... |
