The conundrum of lenticular oncology. A review
Chaturvedi Sunil,Mehrotra Amar,Mittal Sanjeev,Bahadur Harsh
Indian Journal of Ophthalmology , 2003,
Abstract: It is a long - accepted dogma in ophthalmology that the lens is a tumour-free tissue. Yet, in the lens, there is lifelong mitotic activity in the subcapsular epithelium. Therefore, these subcapsular epithelial cells must have the potential for cellular transformation. How then can we explain the fact that no scientist has ever seen a naturally occurring primary tumour of the lens in vivo ? This review discusses the early work of Mann, von Hallermann, Courtois and others who addressed the issue of tumour resistance of the lens.
Study of Heavy Quarkonium with Energy Dependent Potential  [PDF]
Pramila Gupta, Indira Mehrotra
Journal of Modern Physics (JMP) , 2012, DOI: 10.4236/jmp.2012.310189
Abstract: Heavy quark systems (c and b ) have been studied in the nonrelativistic framework using energy dependent interquark potential of the form harmonic oscillator with a small linear term as energy dependent as perturbation plus a inverse square potential. This potential admits exact analytical solution of the Schrodinger equation. Mass spectra, leptonic decay width, root mean square radii (), the expectation value of the radius (r) and <1/r> have been estimated for different quantum mechanical states for and systems. It is observed that energy dependent term in the potential leads to saturation of the mass spectra and degree of saturation is governed by the magnitude of perturbation. The calculated values of leptonic decay widths for 1s state are in very good agreement with the experimental data both for c and b systems.
Planning for Human Development—Experiences in Asia  [PDF]
Santosh Mehrotra, Sarthi Acharya
Theoretical Economics Letters (TEL) , 2017, DOI: 10.4236/tel.2017.76109
Abstract: The Human Development paradigm states that for workers to create value and enjoy the fruits of their labour, they have to be adequately accomplished through better education, skills, adequate nutrition and health, among other factors. It makes a case for investing in people as a precondition for progress. Recent literature on development also notes that economic growth cannot be sustained without people’s inclusion. The essence of a dynamic HD framework, therefore, is that human capital, inclusion and measures to improve people’s empowerment are paramount. Much of Asia was/is labour surplus; hence, making optimal use of the labour in the growth process until the time when labour from the low productivity sectors (read: agrarian sectors) is redeployed elsewhere would be most desirable. This follows from the standard economic theories and is not new. However, the process does not automatically happen; it has to be planned and carefully executed. This paper puts forth a case for HD-based planning: a process where human capital and the economic sectors are brought into an integrated framework. In practical terms, this implies that three factors are addressed to achieve HD: agrarian reforms, industrial policy and human capital. The paper attempts to assess how select Asian countries have progressed on these counts in the recent past. It identifies the raison d’être of the high achievers’ success and the low achievers’ lack of it in the (implicit or explicit) planning process. Finally, it presents a simple model of how an HD-planning framework might look like.
Using a GIS to Assess the Land Movements Hazard: Application on Berhoum Area, Hodna Basin, Algeria  [PDF]
Amar Guettouche
Journal of Geographic Information System (JGIS) , 2019, DOI: 10.4236/jgis.2019.112012
Abstract: Modeling land movements hazard by multi-criteria approach is a line of research to provide a methodological framework for risk mapping. This work is intended to establish a model for mapping “land movements hazard” by GIS approach based on multi-criteria analysis. The methodology is to create thematic maps by combining in GIS, determining factors (slope, lithology, water, …) in triggering landslides phenomena and shrinking-swelling soil, using the method of Weighted Sum Model (WSM). These maps are then combined to provide a hazard map of land movements. The application of this method allows the spatial distribution of different criteria and phenomena in Berhoum area, region of Hodna Basin, eastern Algeria. As a result, the study area has been divided into four different areas: 1) areas with no land movements hazard, 2) areas with a medium land movements hazard, 3) areas with a high land movements hazard, and 4) areas with very high land movements hazard.

American Journal of Plant Sciences (AJPS) , 2013, DOI: 10.4236/ajps.2013.43071
Abstract:

Genome wide analysis of Arabidopsis thaliana reveals a unique genetic arrangement of ACGT motif in the protein phosphatase 2C (PP2C) like promoter (accession number AT5G59220). In the present study, full length, 900 base pair, 500 base pair, 400 base pair and NRM deletion variants of PP2C like promoter were constructed to investigate the activity of PP2C like promoter in the presence of inducers like abscisic acid, jasmonic acid and salicylic acid. The PP2C promoter has three ACGT elements in close vicinity. They are so positioned that they are separated by a spacer of 30 base pair and 5 base pair respectively from each other. The study has shown that ACGTN30ACGT genetic architecture is essential for the promoter to be induced in response to abscisic acid. The synergistic and antagonistic effects of cis elements were observed. AACA is a positive regulatory element in endosperm and is known to act as negative regulatory element in other tissues. In this study AACA, have been found to negatively regulate the expression of reporter gene EGFP in both induced and under uninduced conditions.

To Host or Not to Host? A Comparison Study on the Long-Run Impact of the Olympic Games
Anita Mehrotra
Michigan Journal of Business , 2012,
Abstract: Macroeconomic research on sporting mega-events, like the Olympic Games, often focuses on the short-run economic impact of individual countries. In this paper, I explore the long-run effect of the Olympics on host countries, in general. I analyze hosts in relation to "runner-up" countries, i.e. countries that come in second to the hosts in the bidding process. Upon rectifying anomalies in the data set and including control variables for the initial state of the economy and population, I find that hosts' long-run GDP per capita (GDPpc) is negative in comparison to runner-up countries' at a statistically significant level. This suggests that a one-time spike in government expenditure may lead to long-run detrimental effects: a "reverse multiplier effect" perpetuates the fall in investment demand and consumption levels back to pre-Olympic levels. My results extend the view that individual countries experience a negative economic impact, to the group of host countries in general.
Giant trochanteric pressure sore: Use of a pedicled chimeric perforator flap for cover
Mehrotra Sandeep
Indian Journal of Plastic Surgery , 2009,
Abstract: Pressure sores are increasing in frequency commensurate with an ageing population with multi-system disorders and trauma. Numerous classic options are described for providing stable wound cover. With the burgeoning knowledge on perforator anatomy, recent approaches focus on the use of perforator-based flaps in bedsore surgery. A giant neglected trochanteric pressure sore in a paraplegic is presented. Since conventional options of reconstruction appeared remote, the massive ulcer was successfully managed by a chimeric perforator-based flap. The combined muscle and fasciocutaneous flaps were raised as separate paddles based on the anterolateral thigh perforator branches and provided stable cover without complications. Perforators allow versatility in managing complex wounds without compromising on established principles.
Perforator plus flaps: Optimizing results while preserving function and esthesis
Mehrotra Sandeep
Indian Journal of Plastic Surgery , 2010,
Abstract: Background: The tenuous blood supply of traditional flaps for wound cover combined with collateral damage by sacrifice of functional muscle, truncal vessels, or nerves has been the bane of reconstructive procedures. The concept of perforator plus flaps employs dual vascular supply to flaps. By safeguarding perforators along with supply from its base, robust flaps can be raised in diverse situations. This is achieved while limiting collateral damage and preserving nerves, vessels, and functioning muscle with better function and aesthesis. Materials and Methods: The perforator plus concept was applied in seven different clinical situations. Functional muscle and fasciocutaneous flaps were employed in five and adipofascial flaps in two cases, primarily involving lower extremity defects and back. Adipofascial perforator plus flaps were employed to provide cover for tibial fracture in one patients and chronic venous ulcer in another. Results: All flaps survived without any loss and provided long-term stable cover, both over soft tissue and bone. Functional preservation was achieved in all cases where muscle flaps were employed with no clinical evidence of loss of power. There was no sensory loss or significant oedema in or distal to the flap in both cases where neurovascular continuity was preserved during flap elevation. Fracture union and consolidation were satisfactory. One patient had minimal graft loss over fascia which required application of stored grafts with subsequent take. No patient required re-operation. Conclusions: Perforator plus concept is holistic and applicable to most flap types in varied situations. It permits the exercise of many locoregional flap options while limiting collateral functional damage. Aesthetic considerations are also addressed while raising adipofascial flaps because of no appreciable donor defects. With quick operating times and low failure risk, these flaps can be a better substitute to traditional flaps and at times even free tissue transfers.

Health (Health) , 2013, DOI: 10.4236/health.2013.59203
Abstract:

Background and Objective: There is a rising concern about Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome (HIV/AIDS) related knowledge in rural communities of Sudan. This study focuses on determining the extend of knowledge, beliefs, and attitudes about HIV/ AIDS among rural communities difficult to access in the six States of Sudan. Subjects and Methods: Six thousand and one hundred twenty five respondents were interviewed through the method of house-to-house visits. A structured questionnaire was administered by research assistants recruited from the Faculty of Medicine, Khartoum University during a rural residency campaign in six states of Central, Eastern and Northern Sudan during 2008/2009. Results: Of the total interviewees, 48% were aware of the HIV/AIDS risk; 46% reported to have good health seeking behaviors for HIV/AIDS. 54.4% of women reported to have better knowledge about the disease than men (45.6%). 38% (2005) had not heard of safety use of condom whereas 16% (320) had used it. Logistic regression revealed that 5.3% of knowledge about the disease was explained by gender, education and religion adjusted over age of the respondents. Conclusions: Mass media were the most common source of information about the existent risk of HIV/AIDS in rural communities. These findings could assist Sudanese National Aids Programme (SNAP), healthcare providers and policymakers to develop informative materials and health education programs to educate rural community is about the risk of HIV/AIDS.
