A Note On ℓ\ell-Rauzy Graphs for the Infinite Fibonacci Word

The $\ell$-Rauzy graph of order $k$ for any infinite word is a directed graph in which an arc $(v_1,v_2)$ is formed if the concatenation of the word $v_1$ and the suffix of $v_2$ of length $k-\ell$ is a subword of the infinite word. In this paper, we consider one of the important aperiodic recurrent words, the infinite Fibonacci word for discussion. We prove a few basic properties of the $\ell$-Rauzy graph of the infinite Fibonacci word. We also prove that the $\ell$-Rauzy graphs for the infinite Fibonacci word are strongly connected.Comment: 10 pages, 4 figure

URL ATTACKS: Classification of URLs via Analysis and Learning

Social Networks such as Twitter, Facebook play a remarkable growth in recent years. The ratio of tweets or messages in the form of URLs increases day by day. As the number of URL increases, the probability of fabrication also gets increased using their HTML content as well as by the usage of tiny URLs. It is important to classify the URLs by means of some modern techniques. Conditional redirection method is used here by which the URLs get classified and also the target page that the user needs is achieved. Learning methods also introduced to differentiate the URLs and there by the fabrication is not possible. Also the classifiers will efficiently detect the suspicious URLs using link analysis algorithm

AN ASSESSMENT OF POTENTIAL DRUG-DRUG INTERACTIONS IN HYPERTENSIVE PATIENTS IN A TERTIARY CARE HOSPITAL

Objective: To an assessment of potential drug-drug interactions in hypertensive patients in a tertiary care hospital. Methods: A prospective, observational study was conducted at a tertiary care hospital, Erode for a period of 8 mo. A sample of 480 patients was assessed for PDDIs using drug checker in Micromedex®-2.7. Results: A total of 430 patients were analyzed and it was found to be 396 (82.50%) hypertensive patients had PDDIs, and a sum total of 1160 PDDIs were observed. Potential drug-drug interactions (PDDIs) higher in female hypertensive patients [255 (64.39%)] compared to males. Incidences of PDDIs were found to be higher in the age group of 60-70 y were [177 (44.69%)] and incidences of interactions based on the duration of (4-6 d) hospital stays were 272 (68.68%). Moreover, 49.24% of patients were found to be prescribed with more than 7 drugs, with higher incidences of PDDIs. Some of the most common drug interacting pair was between aspirin and clopidogrel combination observed in 325 PDDIs in the major, with pharmacodynamics in nature. Conclusion: Clinical pharmacist ought to have the role of regular monitoring of drug therapy in identifying and preventing the medications that have the potential to cause drug-drug interactions, thereby minimizing the undesirable outcomes in drug medical care and improving the quality of care

A review on the genus Calophyllum (Clusiaceae): a potential medicinal tree species

Calophyllum is the genus of evergreen tropical flowering plants in the Clusiaceae family. They are predominantly located in Asia with some of its genus distributed in the Pacific Islands, Americas, Australasia and Africa. Plants of the genus are well known for their chemical properties with lots of secondary metabolites such as triterpenes, flavonoids, coumarins and xanthones. Compounds from Calophyllum have been reported to have cytoprotective, anti-HIV, anti-secretory, cytotoxic, antinociceptive, molluscicidal and antimicrobial properties. Some of the plants in Calophyllum are used in folk medicine to treat conditions like peptic ulcers, tumours, inflammation, infections and pain. Calophyllum genus is important with respect to their ecological as well as their medicinal properties. But in India, some species located in Western Ghats are in vulnerable stage. Even so, there is no remarkable studies carried out about this genus. So, for a sustainable environment, we should focus on the conservation, restoration and rehabilitation of the genus that makes huge differences in their population. This article reviews the genus Calophyllum of Western Ghats as a potential medicinal tree species

A critical review of anticancer properties of Withania somnifera (L.) Dunal with respect to the biochemical mechanisms of its phytochemical constituents

Cancer is a leading cause of mortality worldwide, the conventional chemotherapeutic drugs have been known for their toxicity and numerous side effects. A new approach to treat cancer involves phytochemical drugs. In the present review, anti-cancer activity of a class of steroidal lactones called withanolides obtained from Withania somnifera (L.) Dunal is discussed. The commonly studied bioactive compounds namely withaferin-A, withanoside IV, withanoside VI and withanolide-A among others obtained from methanolic and chloroform extract of the leaves and various alcoholic, aqueous and chloroform extract of roots have shown inhibition to various human cancer cell lines including skin, breast, colon, prostate, liver, ovary, cervical and lung. Prominent mechanisms of action include induction of apoptosis by NOS upregulation, ROS production and NBS2 or COX-2 inhibition; cytotoxicity by humoral and cell mediated immune response, activation of p53 and pRB and inhibition of various viral oncoproteins; cell cycle arrest by Cdc2 facilitated mitotic catastrophe, cyclin-D1 down-regulation and inhibition of transcription factors. Cancers are also controlled by inhibition of angiogenesis and metastasis of the tumor cells. In addition to anti-tumorogenic properties, W. somnifera also holds properties that make it a potential adjuvant in integrated cancer therapeutics and in enhancing the effectiveness of ongoing radiation therapy

Heat shock-induced phosphorylation of TAR DNA-binding protein 43 (TDP-43) by MAPK/ERK kinase regulates TDP-43 function

TAR DNA-binding protein (TDP-43) is a highly conserved and essential DNA- and RNA-binding protein that controls gene expression through RNA processing, in particular, regulation of splicing. Intracellular aggregation of TDP-43 is a hallmark of amyotrophic lateral sclerosis and ubiquitin-positive frontotemporal lobar degeneration. This TDP-43 pathology is also present in other types of neurodegeneration including Alzheimer's disease. We report here that TDP-43 is a substrate of MEK, a central kinase in the MAPK/ERK signaling pathway. TDP-43 dual phosphorylation by MEK, at threonine 153 and tyrosine 155 (p-T153/Y155), was dramatically increased by the heat shock response (HSR) in human cells. HSR promotes cell survival under proteotoxic conditions by maintaining protein homeostasis and preventing protein misfolding. MEK is activated by HSR and contributes to the regulation of proteome stability. Phosphorylated TDP-43 was not associated with TDP-43 aggregation, and p-T153/Y155 remained soluble under conditions that promote protein misfolding. We found that active MEK significantly alters TDP-43-regulated splicing and that phosphomimetic substitutions at these two residues reduce binding to GU-rich RNA. Cellular imaging using a phospho-specific p-T153/Y155 antibody showed that phosphorylated TDP-43 was specifically recruited to the nucleoli, suggesting that p-T153/Y155 regulates a previously unappreciated function of TDP-43 in the processing of nucleolar-associated RNA. These findings highlight a new mechanism that regulates TDP-43 function and homeostasis through phosphorylation and, therefore, may contribute to the development of strategies to prevent TDP-43 aggregation and to uncover previously unexplored roles of TDP-43 in cell metabolism

Management of Melon Fly, Bactrocera cucurbitae (Coquillett) Infesting Gherkin:An Areawide Control Programme Adopted in Peninsular India

An area-wide control (AWC) programme was undertaken for management of melon fly, Bactrocera cucurbitae(Coquillet), in 3 km2 area in Kashapura village of Gauribidanur taluk, Chickaballapura District, Karnataka State in peninsular India from 52nd week of 2007 to 30th week of 2010. Implementation of the AWC programme included field sanitation, male annihilation technique (MAT) through para-pheromone, Cue lure, and bait application technique (BAT). This AWC programme resulted in steady decline of melon fly population in the grid area, and corresponding reduction in per cent fruit fly infested gherkin fruits. In the AWC (grid) area, flies trapped per day (FTD) led to attaining suppression (1 to 0.1 FTD) and eradication levels (<0.1 FTD), which is acceptable to the Indian gherkin processing industry. Whereas, in the non-grid area, fruit fly populations perpetuated at infestation level (>1 FTD) during majority of weeks under observation
