Recurrence of nephrotic syndrome/focal segmental glomerulosclerosis following renal transplantation in children

The incidence of recurrence of nephrotic syndrome/focal segmental glomerulosclerosis (NS/FSGS) is variable (~30%). The incidence of recurrence is less in African-Americans than in whites and Hispanics. Graft survival rates are decreased in recipients with FSGS, especially if remission of the NS is not achieved in those with recurrence. Although controversial, the use of living donor (LD) transplants are not contraindicated; however, obligatory heterozygote parental grafts with a podocin mutation should be used with caution. Optimal treatment to induce a remission post-transplant has not been delineated. Pre-transplant and/or prophylactic post-transplant pre-operative plasmapheresis (PP) for high-risk patients—especially those with recurrence in a previous graft—may be promising. An international multicenter controlled study is required to delineate the optimal approach to prevent and/or treat the recurrence of NS/FSGS

Growth following solid organ transplantation in childhood

One of the ultimate goals of successful solid organ transplantation in pediatric recipients is attaining an optimal final adult height. This manuscript will discuss growth following transplantation in pediatric recipients of kidney, liver, heart, lung or small bowel transplants. Remarkably similar factors impact growth in all of these recipients. Age is a primary factor, with younger recipients exhibiting the greatest immediate catch-up growth. Graft function is a significant contributing factor, with a reduced glomerular filtration rate correlating with poor growth in kidney recipients and the need for re-transplantation with impaired growth in liver recipients. The known adverse impact of steroids on growth has led to modification of the steroid dose and even steroid withdrawal and avoidance. In kidney and liver recipients, this strategy has been associated with the development of acute rejection. In infant heart transplantation, avoiding maintenance corticosteroid immunosuppression is associated with normal growth velocity in the majority of patients. With marked improvements in patient and graft survival rates in pediatric organ recipients, quality of life issues, such as normal adult height, should now receive paramount attention. In general, normal growth following solid organ transplantation should be an achievable goal that results in normal adult height

The Corporate Governance Debate and the ALI Proposals: Reform or Restatement?

Much of the debate concerning corporate governance centers on the American Law Institute\u27s proposed Principles of Corporate Governance [hereinafter ALI Proposals or ALI Principles].\u27 The restate the law of corporate governance without departing from the primary goal stated in the ALI\u27s charter: to promote the clarification and simplification of the law and its better adaptation to social needs. \u27 The ALI Proposals, however, have evolved into a new art form \u27 and, unlike a restatement, have proposed reforms in addition to codifying the common law. Because of the predominance of statutory corporation law, the ALI Proposals have focused selectively on those areas that usually are governed by common law. The ALI Proposals have seven parts: (1) Definitions; (2)Objectives and Conduct of the Business Corporation; (3) Structure of the Corporation; (4) Duty of Care and the Business Judgment Rule; (5) Duty of Loyalty; (6) Transactions in Control; and (7) Remedies.\u2

Reduction of Soil-Borne Plant Pathogens Using Lime and Ammonia Evolved from Broiler Litter

In laboratory and micro-plots simulations and in a commercial greenhouse, soil ammonia (NH3) and pH were manipulated as means to control soil-borne fungal pathogens and nematodes. Soil ammonification capacity was increased by applying low C/N ratio broiler litter at 1–8% (w/w). Soil pH was increased using lime at 0.5–1% (w/w). This reduced fungi (Fusarium oxysporum f. sp. dianthi and Sclerotium rolfsii) and root-knot nematode (Meloidogyne javanica) in lab tests below detection. In a commercial greenhouse, broiler litter (25 Mg ha−1) and lime (12.5 Mg ha−1) addition to soil in combination with solarization significantly reduced M. javanica induced root galling of tomato test plants from 47% in the control plots (solarization only) to 7% in treated plots. Root galling index of pepper plants, measured 178 days after planting in the treated and control plots, were 0.8 and 1.5, respectively, which was statistically significantly different. However, the numbers of nematode juveniles in the root zone soil counted 83 and 127 days after pepper planting were not significantly different between treatments. Pepper fruit yield was not different between treatments. Soil disinfection and curing was completed within one month, and by the time of bell-pepper planting the pH and ammonia values were normal

Diamonds are Forever

We defend the thesis that every necessarily true proposition is always true. Since not every proposition that is always true is necessarily true, our thesis is at odds with theories of modality and time, such as those of Kit Fine and David Kaplan, which posit a fundamental symmetry between modal and tense operators. According to such theories, just as it is a contingent matter what is true at a given time, it is likewise a temporary matter what is true at a given possible world; so a proposition that is now true at all worlds, and thus necessarily true, may yet at some past or future time be false in the actual world, and thus not always true. We reconstruct and criticize several lines of argument in favor of this picture, and then argue against the picture on the grounds that it is inconsistent with certain sorts of contingency in the structure of time

The Bell Theorem as a Special Case of a Theorem of Bass

The theorem of Bell states that certain results of quantum mechanics violate inequalities that are valid for objective local random variables. We show that the inequalities of Bell are special cases of theorems found ten years earlier by Bass and stated in full generality by Vorob'ev. This fact implies precise necessary and sufficient mathematical conditions for the validity of the Bell inequalities. We show that these precise conditions differ significantly from the definition of objective local variable spaces and as an application that the Bell inequalities may be violated even for objective local random variables.Comment: 15 pages, 2 figure

Rings of Quotients of Rings of Functions

From the original PREFACE: The rings of quotients recently introduced by Johnson and Utumi are applied to the ring $C(X)$ of all continuous real-valued functions on a completely regular space $X$. Let $Q(X)$ denote the maximal ring of quotients of $C(X)$; then $Q(X)$ may be realized as the ring of all continuous functions on the dense open sets of $X$ (modulo an obvious equivalence relation). In special cases (e.g., for metric $X$), $Q(X)$ reduces to the classical ring of quotients of $C(X)$ (formed with respect to the regular elements), but in general, the classical ring is only a proper sub-ring of $Q(X)$.Comment: 72 pages, Typeset copy of 1966 original, long out of prin

EPIGENETIC STUDY AS A NEW APPROACH FOR THERAPEUTICS AND BIOMARKER OF ATHEROSCLEROSIS IN COVID-19

Introduction : Coronavirus disease 2019 (COVID-19) has affected more than 105 million people globally and resulted in at least 2.3 million deaths. Covid-19 has highlighted the vulnerability of aging populations to emerging diseases. This susceptibility to disease and death is also a major challenge for the development of vaccines and immunotherapeutic agents. Atherosclerosis is one of the main cardiovascular disease, and this disease is one of the most common comorbid diseases affected by Covid-19 and is associated with increased risk of mortality. Biomarker are crucial in decision-making in order to facilitate efficient resource allocation. Recently many researcher develop several biomarker as a new approach in epigenetic area. The discovery of new therapeutic targets as well as biomarkers using epigenetic studies may increase its clinical usefulness. Methods: In this narrative review, a search was carried out with the help of several search engines that match the criteria, namely "Epigenetic Studies Based On Cardiovascular Disease Especially In Atherosclerosis".Results: One paper was obtained that supports and fits the criteria, namely the role of miRNA in the formation of atherosclerotic plaques.Conclusion: miR-486-5p can be used as a new therapeutic target and biomarker in atherosclerosis patients, but this requires further researc
