Herbal medicine: the magic way crouching microbial resistance
No full textBacterial resistance to antibiotics poses a high level of danger worldwide. Bacterial resistance mechanisms are spreading globally, impeding our ability to treat common infectious diseases. Misuse and overuse of antibiotics accelerate microbial resistance
to antibiotics. Despite the exerted efforts, none of the newly developed antibiotics are expected to be effective against the dangerous forms of antibiotic-resistant bacteria. Since many plants have been shown to contain powerful antimicrobial compounds
that can act synergistically or alternatively to antibiotics, the demand for herbal medicines has recently increased to cotreat microbes that are resistant to antibiotics. Maximum benefit can be achieved when the pharmacokinetics and pharmacodynamics
of natural products match the antibiotic. This review article refers to nine highly effective and key herbs to use alongside antibiotics to overcome crises of antibiotic resistance. Their unique molecular mechanisms of action have been highlighted

Dibenzyl ferrocene-1,1′-dicarboxylate
No full textIn the title compound, [Fe(C13H11O2)2], there are markedly different orientations of the two phenylmethoxycarbonyl substituents [O—C—C—C torsion angles = 84.5 (3) and 139.6 (2)°]. These orientations are mediated by a number of intermolecular C—H...O interactions, which result in a one-dimensional hydrogen-bonded network of molecules
Online conductivity monitoring of dialysis adequacy versus Kt/V derived from urea reduction ratio: A prospective study from a Saudi center

No full textThe purpose of this article is to analyze and compare the novel by the Spanish writer Camilo José Cela and the Egyptian author Alaa al-Aswany, emphasizing the features of poverty and sex in the two novels: La colmena (1951) and The Yacobian building (2002). We also highlight the causes and circumstances that led some characters to resort to sex as their only alternative and escape route in one society as in the other. Therefore, this research work approach both the Spanish and the Egyptian reality to which the author refers.Este trabajo de investigación consiste en el análisis y la comparación de la novela del escritor español Camilo José Cela y el egipcio Alaa al-Aswany haciendo hincapié en los rasgos de pobreza y sexo en las dos novelas: La colmena (1951) y El edificio Yacobian (2002). También subrayamos las causas y circunstancias que llevaron a algunos personajes en recurrir al sexo como su única alternativa y vía de escape tanto en una sociedad como en la otra.

Methodology to Improve Energy Efficiency of Heritage Buildings Using HBIM-Sabil Qaitbay: A Case Study from Egypt
No full textOver the last few decades, reducing energy consumption in existing buildings became vital. Although architectural heritage values do not allow typical retrofit interventions, research and practice have demonstrated that heritage buildings can be energy efficient without compromising the building’s heritage values. This article shows the results of energy analysis performed on heritage buildings with HBIM-based simulations such as Revit, Insight, and Green Building Studio. These tools were used to study the energy performance and thermal comfort of Sabil Qaitbay in Cairo, a heritage building built in the fifteenth century, and it is currently used as a library and school for cinema and television. The building history and the conservation values of the current project were studied. Then, the methodology to improve the energy efficiency of heritage buildings using HBIM was discussed. Moreover, two proposals were applied to the current base case, and the potential energy saving for each proposed intervention was investigated. The simulation confirmed a possible reduction of 18.7% in energy consumption with the lowest-cost interventions and 33% with the highest-cost interventions
Online conductivity monitoring of dialysis adequacy versus Kt/V derived from urea reduction ratio: A prospective study from a Saudi center
No full textKhalid Al Saran1, Alaa Sabry2, Mamdouh Abdulghafour1, Ahmed Yehia11Prince Salman Center for Kidney Disease, Riyadh, Kingdom of Saudi Arabia; 2Mansoura Urology and Nephrology Center, Mansoura University, Mansoura, EgyptIntroduction: Ad equate delivered dose of solute removal (as assessed by urea reduction and calculation of Kt/V) is an important determinant of clinical outcome in chronic hemodialysis (HD) patients. This requires both prescription of an adequate dose of HD and regular assessment that the delivered treatments are also adequate. Online conductivity monitoring using sodium flux as a surrogate for urea allows the repeated noninvasive measurement of Kt/V on each HD treatment.Methods: We prospectively studied 17 (9 males, 8 females) established chronic HD patients over an eight-week period (408 treatments). A pre- and post-dialyzer measurement of the conductivity is performed by two mutually independent temperature-compensated conductivity cells equipped with Fresenius 4008 S® dialysis machines. Urea reduction was measured (once a week) by a single pool calculation using immediate post-treatment sampling. No changes were made to any of the dialysis prescriptions over the study period. Values of calculated Kt/V and simultaneously obtained online Kt/V were compared.Results: There was a statistically significant difference between calculated Kt/V and online Kt/V over the study period. The mean calculated Kt/V was 1.37 ± 0.09, and mean online Kt/V 1.02 ± 0.15 (P = 0.000), calculated Kt/V ≥ 1.2 was achieved in all our patients while online Kt/V ≥ 1.2 was achieved in only 17.64 %. Yet there was moderate correlation between calculated Kt/V and online Kt/V (r2 = 0.48).Conclusions: Online conductivity monitoring results underestimates dialysis efficiency compared to calculated Kt/V readings. This difference has to be considered when applying Kt/V to clinical practice.Keywords: Kt/V, hemodialysis, online conductivity monitorin
Epic of the palm tree in Los Angeles
No full textThesis: M. Arch., Massachusetts Institute of Technology, Department of Architecture, 2018.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Cataloged from student-submitted PDF version of thesis.Includes bibliographical references (pages 84-85).The Palm Tree of Los Angeles is it's own entity. It is spelled with a capital P and T. It is also inherently contranymic. (A contranym is defined as a word with two opposite meanings.) Although referred to as "tree," it biologically is not. It is a monocot, similar to grass. Although it is completely embedded into the making of Los Angeles, it is not native to the city at all. Different palm trees from around the world, along with their stories, have participated in constructing myths continuously perpetuated in and by Los Angeles. Current myth making, however, perpetuates a flat, simple narrative. This thesis brings multiple dimensions of positive and negative narratives forward in one continual experience, collapsing these into an alternative mythology. The proposal moves from a flat representation to a collapsed representation. Flat representation is when the myth references only a single story, whereas collapsed representation allows the myth to reference multiple stories. This shift is a new approach on reading the city's history, creating an alternative mythology. By using an aesthetic of Persian miniatures, the thesis re-orientalizes representations of the palm tree. I use the term re-orientalize intentionally, also calling to a re-orienting of the interpreter. This thesis uses a flat aesthetic, but tells a collapsed mythology. The proposal is architecturalized through a series of interventions in the city that can be approached either on their own, or as a constructed loop. The series of interventions are put together as a "nameh," which is a book from a Persian tradition that tells a type of history through painting and verse. This is the Palmnameh: The Epic of The Palm.by Alaa Quraishi.M. Arch
