    Role of Proteome Physical Chemistry in Cell Behavior.

    We review how major cell behaviors, such as bacterial growth laws, are derived from the physical chemistry of the cell's proteins. On one hand, cell actions depend on the individual biological functionalities of their many genes and proteins. On the other hand, the common physics among proteins can be as important as the unique biology that distinguishes them. For example, bacterial growth rates depend strongly on temperature. This dependence can be explained by the folding stabilities across a cell's proteome. Such modeling explains how thermophilic and mesophilic organisms differ, and how oxidative damage of highly charged proteins can lead to unfolding and aggregation in aging cells. Cells have characteristic time scales. For example, E. coli can duplicate as fast as 2-3 times per hour. These time scales can be explained by protein dynamics (the rates of synthesis and degradation, folding, and diffusional transport). It rationalizes how bacterial growth is slowed down by added salt. In the same way that the behaviors of inanimate materials can be expressed in terms of the statistical distributions of atoms and molecules, some cell behaviors can be expressed in terms of distributions of protein properties, giving insights into the microscopic basis of growth laws in simple cells

    Assessment of Metabolic Parameters For Autism Spectrum Disorders

    Get PDF
    Autism is a brain development disorder that first appears during infancy or childhood, and generally follows a steady course without remission. Impairments result from maturation-related changes in various systems of the brain. Autism is one of the five pervasive developmental disorders (PDD), which are characterized by widespread abnormalities of social interactions and communication, and severely restricted interests and highly repetitive behavior. The reported incidence of autism spectrum disorders (ASDs) has increased markedly over the past decade. The Centre for Disease Control and Prevention has recently estimated the prevalence of ASDs in the United States at approximately 5.6 per 1000 (1 of 155 to 1 of 160) children. Several metabolic defects, such as phenylketonuria, are associated with autistic symptoms. In deciding upon the appropriate evaluation scheme a clinician must consider a host of different factors. The guidelines in this article have been developed to assist the clinician in the consideration of these factors

    On colouring point visibility graphs

    In this paper we show that it can be decided in polynomial time whether or not the visibility graph of a given point set is 4-colourable, and such a 4-colouring, if it exists, can also be constructed in polynomial time. We show that the problem of deciding whether the visibility graph of a point set is 5-colourable, is NP-complete. We give an example of a point visibility graph that has chromatic number 6 while its clique number is only 4

    This study examines and discusses the overview of the contributions made by the Indian Universities that signed MOU to the Open Access repository with INFLIBNET namely Shodhganga. 463 universities are contributing 247285 theses in Shodhganga in the INFLIBNET list as of 24.04.2020 where the State Universities contributed 195913 theses (79.22percent). Tamil Nadu contributed the highest number of theses 46416 where a maximum of 11908 theses was contributed by the individual university from Calcutta University, West Bengal. A total of 463 universities, 187 of the state universities, 140 of those are private universities, 88 of which are deemed universities and 3 of which are CFTI universities and the remaining 45 of which are central universities, that all keep e-theses in the Shodhganga repository. Tamil Nadu has the largest number (46) of universities depositing these into the repository. The investigator also examined that a total of 31 states use plagiarism detection software through the INFLIBNET-initiated Shodhshuddhi project with 1032 institutes/universities

    An Event Study Approach to Analyse the Impact of Novel Coronavirus Disease (Covid-19) on Indian Hotel & Tourism Stocks Performance

    Get PDF
    Covid 19 or the Novel Corona Virus outbreak in 2020 has disrupted the world and Indian economy. Tourism industry has suffered the most due to this outbreak. The hotel industry stocks have experience an average fall of twenty three percent within a month of the Covid 19 outbreak. With the help of event-study approach, an attempt has been made to analyse the effect of Covid 19 on Indian hotel stock price movements. Six publicly traded hotel and tourism companies experience a steep fall in their stock prices during the Covid 19 outbreak period. On and after the day the World Health Organisation declared Covid 19 a pandemic, Indian hotel stocks exhibited significant negative cumulative mean abnormal returns, indicating a significant impact of the Covid 19 outbreak on hotel stock performance. Empirical finding can enable Businesses to prepare themselves for alternate uses like isolation wards and save themselves from economic plight

    Sentinel node detection in early breast cancer with intraoperative portable gamma camera: UK experience.

    Get PDF
    PURPOSE: Access to nuclear medicine department for sentinel node imaging remains an issue in number of hospitals in the UK and many parts of the world. Sentinella(®) is a portable imaging camera used intra-operatively to produce real time visual localisation of sentinel lymph nodes. METHODS: Sentinella(®) was tested in a controlled laboratory environment at our centre and we report our experience on the first use of this technology from UK. Moreover, preoperative scintigrams of the axilla were obtained in 144 patients undergoing sentinel node biopsy using conventional gamma camera. Sentinella(®) scans were done intra-operatively to correlate with the pre-operative scintigram and to determine presence of any residual hot node after the axilla was deemed to be clear based on the silence of the hand held gamma probe. RESULTS: Sentinella(®) detected significantly more nodes compared with CGC (p < 0.0001). Sentinella(®) picked up extra nodes in 5/144 cases after the axilla was found silent using hand held gamma probe. In 2/144 cases, extra nodes detected by Sentinella(®) confirmed presence of tumour cells that led to a complete axillary clearance. CONCLUSIONS: Sentinella(®) is a reliable technique for intra-operative localisation of radioactive nodes. It provides increased nodal visualisation rates compared to static scintigram imaging and proves to be an important tool for harvesting all hot sentinel nodes. This portable gamma camera can definitely replace the use of conventional lymphoscintigrams saving time and money both for patients and the health system

    Back reaction, emission spectrum and entropy spectroscopy

    Full text link
    Recently, an interesting work, which reformulates the tunneling framework to directly produce the Hawking emission spectrum and entropy spectroscopy in the tunneling picture, has been received a broad attention. However, during the emission process, most related observations have not incorporated the effects of back reaction on the background spacetime, whose derivations are therefore not the desiring results for the real physical process. With this point as a central motivation, in this paper we suitably adapt the \emph{reformulated} tunneling framework so that it can well accommodate the effects of back reaction to produce the Hawking emission spectrum and entropy spectroscopy. Consequently, we interestingly find that, when back reaction is considered, the Parikh-Wilczek's outstanding observations that, an isolated radiating black hole has an unitary-evolving emission spectrum that is \emph{not} precisely thermal, but is related to the change of the Bekenstein-Hawking entropy, can also be reproduced in the reformulated tunneling framework, meanwhile the entropy spectrum has the same form as that without inclusion of back reaction, which demonstrates the entropy quantum is \emph{independent} of the effects of back reaction. As our final analysis, we concentrate on the issues of the black hole information, but \emph{unfortunately} find that, even including the effects of back reaction and higher-order quantum corrections, such tunneling formalism can still not provide a mechanism for preserving the black hole information.Comment: 16 pages, no figure, use JHEP3.cls. to be published in JHE
