The hidden/flying dragon : an exploration of the Book of Changes (I Ching) in terms of Nietzscheâs philosophy
The ancient Chinese I Ching, the Book of Changes, and the philosophy of the German philosopher Friedrich Nietzsche (1844-1900) both assert that the universe exists in a state of change. The I Ching, originally a book of divination, illustrates the changing phenomena of the natural world in terms of sixty-four hexagrams, which are figures composed of six lines yielding and firm lines, representing actual conditions and relationships existing in the world and caused by the interplay between two primordial forces, yin and yang. The I Ching shows that on the macro level the Tao works in the universe, in heaven and on earth, and on the micro level it applies to man. The I Ching teaches harmony with Tao and its power (natural law and moral law), so that its reader may take appropriate action in any given situation with reference to the hexagrams and their appended judgments as revealed by the oracle. Nietzsche, however, regards the world as the Will to Power, âa monster of energyâ, like a storming and flooding ocean eternally changing, where harmony and order seems impossible. His mouthpiece, Zarathustra, who teaches the Ăbermensch, encourages a war-like attitude towards life. Zarathustraâs second metamorphosis of an evolving spirit, the warrior lion, marks the difference between the Nietzschean Ăbermensch and the Chinese sage who attains harmony and balance within and without, a mysterious union with heaven. Zarathustraâs third metamorphosis, a playing child, creates itself as its own âbridgeâ through a process of self-overcoming, whereas the I Ching indicates order to be the âbridgeâ over chaos, the order of the human world being expressed in the five cardinal relationships. Whereas the I Ching advises its reader to follow their own nature and fate in order to lead a harmonious moral life, Nietzscheâs Ăbermensch is âthe annihilator of moralityâ and paradoxically âthe designation of a type of supreme achievementâ (EH Books 1). With his idea of the Ăbermensch, Nietzsche indicates that morality is a pose (BGE 216). He seeks to make us become aware that we should invent our own virtue and create our own way in order to become what we are. He criticizes Christian morality, calling himself âthe first immoralistâ. His shocking approach attempts to make us become aware of the possibility that a ânoble moralityâ and âhigher moralitiesâ ought to be possible. His Ăbermensch represents such a higher mode of existence. Zarathustra also teaches the doctrine of eternal recurrence, implying that moment is eternity, changelessness within change. Multifarious manifestations are the expression of the Tao. Everything is interconnected and interdependent. Whereas ordinary men see the continuity of phenomena as real, enlightened beings are aware of the transitory and illusive nature of the self and all things. The Nietzschean Ăbermensch embodies the characteristics of an enlightened being, a Buddha or Bodhisattva in Buddhist terms, characteristics such as wisdom and compassion. Therefore, the practice of the Bodhisattva is explored as a feasible way for actualizing the Nietzschean hypothetical Ăbermensch.Thesis (DPhil)--University of Pretoria, 2009.Philosophyunrestricte
Where does morality come from? Aspects of Nietzscheâs genealogical critique of morality and his idea of the Ăbermensch
With this dissertation, firstly, I address the issue of Friedrich Nietzscheâs (1844-1900) so-called âimmoralismâ. When he calls himself an âimmoralistâ and even âthe first immoralistâ (EH Destiny 2), he seems to be the first philosopher to consider morality as something negative, something we had better got rid of. Yet, he favours ânoble moralityâ and âhigher moralitiesâ which he insists ought to be possible (BGE 202). I shall interpret Nietzscheâs explicit claim of âimmoralismâ and his âcampaign against moralityâ as a rejection of a particular kind of morality Ÿ Christian morality âthat has become prevalent and predominant as morality itselfâ (EH Destiny 4). His âimmoralismâ does not reject the idea of an ethical life. Nietzsche favours a âsupra-moralâ version of life (GM II 2&BGE 257). The move from a moral to a supra-moral orientation to life implies a kind of self-overcoming, a process which has both a ânegativeâ (âdestructiveâ) and a âpositiveâ (âproductiveâ) side. Firstly, I shall give an account of the ânegativeâ side, which involves Nietzscheâs genealogical critique of morality. In his Genealogy, Nietzsche criticizes the man of ressentiment, the metaphysical two-worlds distinction: âtrue worldâ and âapparent worldâ, and the ascetic ideal of the will to truth, which he considers as a will to nothingness (GM III 28). His notion of perspectivism advocates a plurality of values and perspectives as opposed to any notion of an absolute truth. Then, I shall look into his âpositiveâ ethic, as exemplified in the figures of Zarathustra and the Ăbermensch, and the paradox of the Ăbermenschas âthe annihilator of moralityâ (EH Books 1) and as âthe designation of a type of supreme achievementâ (EH Books 1). By proclaiming a process of âself-overcoming of moralityâ (BGE 32), I believe that Nietzsche proposes an experimental morality in order to improve mankind. He considers morality as a pose, as progress (BGE 216), and âmere symptomatologyâ (TI âImproversâ of Mankind 1). Morality is the effect, or symptom of a continuous improvement within an individual. Nietzsche seeks to make us become aware of our continuous self-improvement, that we should invent our own virtue (A 11) in order to become what we are. Nietzsche envisions the possibility of evolving a magnanimous and courageous human type who is capable of giving style to his character (GS 290), the supreme human achievement Ÿ the Ăbermensch. His idea of the Ăbermensch implies a never-ending struggle for self-perfection and self-fulfilment. There are affinities between Nietzscheâs philosophy and Buddhism, such as emphasizing practice, the recognition of the transient nature of human existence, and an emphasis on impermanence. Buddhist teachings show various feasible ways to attain enlightenment and buddhahood. The path to enlightenment and buddhahood can be shown to share some features with Nietzscheâs process of self-overcoming, which leads to self-transformation and self-perfection. The emphasis on the practice of the spirit of Bodhisattva by Humanistic Buddhism seems to lend itself as complement to Nietzscheâs philosophy, a notion I explore in the concluding chapter of the dissertation.Dissertation (MA (Philosophy))--University of Pretoria, 2005.Philosophyunrestricte

Selective predisposition to bacterial infections in IRAK-4âdeficient children: IRAK-4âdependent TLRs are otherwise redundant in protective immunity
Human interleukin (IL) 1 receptorâassociated kinase 4 (IRAK-4) deficiency is a recently discovered primary immunodeficiency that impairs Toll/IL-1R immunity, except for the Toll-like receptor (TLR) 3â and TLR4âinterferon (IFN)-a/b pathways. The clinical and immunological phenotype remains largely unknown. We diagnosed up to 28 patients with IRAK-4 deficiency, tested blood TLR responses for individual leukocyte subsets, and TLR responses for multiple cytokines. The patients' peripheral blood mononuclear cells (PBMCs) did not induce the 11 non-IFN cytokines tested upon activation with TLR agonists other than the nonspecific TLR3 agonist poly(I:C). The patients' individual cell subsets from both myeloid (granulocytes, monocytes, monocyte-derived dendritic cells [MDDCs], myeloid DCs [MDCs], and plasmacytoid DCs) and lymphoid (B, T, and NK cells) lineages did not respond to the TLR agonists that stimulated control cells, with the exception of residual responses to poly(I:C) and lipopolysaccharide in MDCs and MDDCs. Most patients (22 out of 28; 79%) suffered from invasive pneumococcal disease, which was often recurrent (13 out of 22; 59%). Other infections were rare, with the exception of severe staphylococcal disease (9 out of 28; 32%). Almost half of the patients died (12 out of 28; 43%). No death and no invasive infection occurred in patients older than 8 and 14 yr, respectively. The IRAK-4âdependent TLRs and IL-1Rs are therefore vital for childhood immunity to pyogenic bacteria, particularly Streptococcus pneumoniae. Conversely, IRAK-4âdependent human TLRs appear to play a redundant role in protective immunity to most infections, at most limited to childhood immunity to some pyogenic bacteria
Evaluation of six CTLA-4 polymorphisms in high-risk melanoma patients receiving adjuvant interferon therapy in the He13A/98 multicenter trial
<p>ABSTRACT</p> <p>Purpose</p> <p>Interferon is approved for adjuvant treatment of patients with stage IIb/III melanoma. The toxicity and uncertainty regarding survival benefits of interferon have qualified its acceptance, despite significant durable relapse prevention in a fraction of patients. Predictive biomarkers that would enable selection of patients for therapy would have a large impact upon clinical practice. Specific CTLA-4 polymorphisms have previously shown an association with response to CTLA-4 blockade in patients with metastatic melanoma and the development of autoimmunity.</p> <p>Experimental design</p> <p>286 melanoma patients and 288 healthy controls were genotyped for six CTLA-4 polymorphisms previously suggested to be important (AG 49, CT 318, CT 60, JO 27, JO30 and JO 31). Specific allele frequencies were compared between the healthy and patient populations, as well as presence or absence of these in relation to recurrence. Alleles related to autoimmune disease were also investigated.</p> <p>Results</p> <p>No significant differences were found between the distributions of CTLA-4 polymorphisms in the melanoma population compared with healthy controls. Relapse free survival (RFS) and overall survival (OS) did not differ significantly between patients with the alleles represented by these polymorphisms. No correlation between autoimmunity and specific alleles was shown. The six polymorphisms evaluated where strongly associated (Fisher's exact p-values < 0.001 for all associations) and significant linkage disequilibrium among these was indicated.</p> <p>Conclusion</p> <p>No polymorphisms of CTLA-4 defined by the SNPs studied were correlated with improved RFS, OS, or autoimmunity in this high-risk group of melanoma patients.</p
Discovery of a novel dominant mutation in the REN gene after forty years of renal disease: a case report.
Heterozygous mutations in the gene encoding renin (REN) cause autosomal dominant tubulointerstitial kidney disease (ADTKD), early-onset anaemia and hyperuricaemia; only four different mutations have been described in the published literature to date. We report a novel dominant REN mutation discovered in an individual after forty years of renal disease.This article is freely available via Open Access.

Autoantibodies against type I IFNs in patients with critical influenza pneumonia
In an international cohort of 279 patients with hypoxemic influenza pneumonia, we identified 13 patients (4.6%) with autoantibodies neutralizing IFN-alpha and/or -omega, which were previously reported to underlie 15% cases of life-threatening COVID-19 pneumonia and one third of severe adverse reactions to live-attenuated yellow fever vaccine. Autoantibodies neutralizing type I interferons (IFNs) can underlie critical COVID-19 pneumonia and yellow fever vaccine disease. We report here on 13 patients harboring autoantibodies neutralizing IFN-alpha 2 alone (five patients) or with IFN-omega (eight patients) from a cohort of 279 patients (4.7%) aged 6-73 yr with critical influenza pneumonia. Nine and four patients had antibodies neutralizing high and low concentrations, respectively, of IFN-alpha 2, and six and two patients had antibodies neutralizing high and low concentrations, respectively, of IFN-omega. The patients' autoantibodies increased influenza A virus replication in both A549 cells and reconstituted human airway epithelia. The prevalence of these antibodies was significantly higher than that in the general population for patients 70 yr of age (3.1 vs. 4.4%, P = 0.68). The risk of critical influenza was highest in patients with antibodies neutralizing high concentrations of both IFN-alpha 2 and IFN-omega (OR = 11.7, P = 1.3 x 10(-5)), especially those <70 yr old (OR = 139.9, P = 3.1 x 10(-10)). We also identified 10 patients in additional influenza patient cohorts. Autoantibodies neutralizing type I IFNs account for similar to 5% of cases of life-threatening influenza pneumonia in patients <70 yr old
Higher COVID-19 pneumonia risk associated with anti-IFN-α than with anti-IFN-Ï auto-Abs in children
We found that 19 (10.4%) of 183 unvaccinated children hospitalized for COVID-19 pneumonia had autoantibodies (auto-Abs) neutralizing type I IFNs (IFN-alpha 2 in 10 patients: IFN-alpha 2 only in three, IFN-alpha 2 plus IFN-omega in five, and IFN-alpha 2, IFN-omega plus IFN-beta in two; IFN-omega only in nine patients). Seven children (3.8%) had Abs neutralizing at least 10 ng/ml of one IFN, whereas the other 12 (6.6%) had Abs neutralizing only 100 pg/ml. The auto-Abs neutralized both unglycosylated and glycosylated IFNs. We also detected auto-Abs neutralizing 100 pg/ml IFN-alpha 2 in 4 of 2,267 uninfected children (0.2%) and auto-Abs neutralizing IFN-omega in 45 children (2%). The odds ratios (ORs) for life-threatening COVID-19 pneumonia were, therefore, higher for auto-Abs neutralizing IFN-alpha 2 only (OR [95% CI] = 67.6 [5.7-9,196.6]) than for auto-Abs neutralizing IFN-. only (OR [95% CI] = 2.6 [1.2-5.3]). ORs were also higher for auto-Abs neutralizing high concentrations (OR [95% CI] = 12.9 [4.6-35.9]) than for those neutralizing low concentrations (OR [95% CI] = 5.5 [3.1-9.6]) of IFN-omega and/or IFN-alpha 2

Robust estimation of bacterial cell count from optical density
Optical density (OD) is widely used to estimate the density of cells in liquid culture, but cannot be compared between instruments without a standardized calibration protocol and is challenging to relate to actual cell count. We address this with an interlaboratory study comparing three simple, low-cost, and highly accessible OD calibration protocols across 244 laboratories, applied to eight strains of constitutive GFP-expressing E. coli. Based on our results, we recommend calibrating OD to estimated cell count using serial dilution of silica microspheres, which produces highly precise calibration (95.5% of residuals <1.2-fold), is easily assessed for quality control, also assesses instrument effective linear range, and can be combined with fluorescence calibration to obtain units of Molecules of Equivalent Fluorescein (MEFL) per cell, allowing direct comparison and data fusion with flow cytometry measurements: in our study, fluorescence per cell measurements showed only a 1.07-fold mean difference between plate reader and flow cytometry data
