Choroidal Metastasis as First Presenting Sign of Renal Cell Carcinoma without Evidence of Primary Tumour - A Case Report
Authors: Mohd Feendi Bin Mohd Fauzi Yap  , Othmaliza Othman  , Rona Asnida Nasaruddin  
Published: June 2022

Renal cell carcinoma (RCC) is a rare malignancy characterized by a variety of clinical features. It represents approximately 3 % of all adult malignancies and ranks 13th in frequency of all carcinomas.[1,2] RCC has been documented to metastasize to every organ in the body although metastasis to the eye and orbit is uncommon. Metastases may present decades after the removal of the primary disease. However, it is uncommon for patients who present with ocular metastasis before primary RCC is identified. We report a rare and unique case of metastatic renal cell carcinoma presenting as a choroidal mass despite no evidence of a primary tumour.
We present a case of a 65-year-old Chinese man who had sought treatment for a right-sided painful blind eye for 2 years which progressively worsened over time. His vision was poor since the age of 15 years and he was unsure of the cause. Initially, he was treated for the painful blind eye secondary to glaucoma and went for evisceration. Intraoperatively, we noticed that his vitreous cavity was filled with hard fibrotic mass. Histopathological examination was reported as right eye metastatic renal cell carcinoma with clear cell variant. Further investigation was done and he underwent exenteration in view of right optic nerve bulkiness which was also related to renal cell carcinoma. Interestingly, no tumour marker was positive and computed tomography (CT) thorax, abdomen and pelvis did not reveal any primary tumour. He did not complain of any adverse urinary symptoms and there were no signs and symptoms to suggest a concurrent renal pathology.
We report a rare and unique case of metastatic renal cell carcinoma presenting as a choroidal mass as the first presenting sign without evidence of primary tumour. Differential diagnosis of metastases must be considered in patients who present with an ocular mass, despite being asymptomatic of any primary malignancy. This is to ensure that this condition is promptly identified and treatment initiated as soon as possible. By highlighting this case, we seek to bring awareness to this condition and hopefully improve on its current dismal prognosis by early diagnosis.

Dispatchable power supply from beam down solar point concentrator coupled to thermal energy storage and a Stirling engine
Authors: Boretti Alberto , al Maaitah Ayman 
Published: June 2022

Abstract
A high concentration high-temperature beam down solar point concentrator is proposed, coupled to thermal energy storage and a Stirling engine to deliver fully dispatchable electricity over 24 h. Full 24 h operation at nominal power is permitted during the month of maximum solar energy collection while in the month of minimum solar energy collection, the full power production is limited to 17.06 h. The monthly average capacity factors oscillate between 71 and 100%, with an average of 87.5%. Thanks to an electric heater for the heat storage fluid, the system can accept excess electricity from the grid to compensate for the loss of the solar energy collected every other month versus the solar energy collected during the best summer month, to operate at rated power 24 h a day in every day of the year. In this case, the capacity factor can reach 100% every month. By further increasing the size of the thermal energy storage and the power of the engine, the electric thermal energy storage capability of the system can be enhanced, increasing the amount of electricity otherwise wasted that could be collected from the grid to be then returned when needed.
Does the ontological proof of God’s existence really contain all the probative force of the cosmological argument? The early criticisms of Kant’s thesis by Flatt, Abel and Eberhard
Authors: Rovira Rogelio 
Published: June 2022

Abstract
Shortly after the appearance of the Critique of Pure Reason, Kant’s claim that the ontological proof of God’s existence contains all the probative force of the cosmological argument was discussed at great length by J. F. Flatt, J. F. v. Abel and J. A. Eberhard. These early criticisms do not seem to have received the attention they deserve, even though they are extremely relevant, cogent, and difficult to dispute. Regardless of whether their assumptions are accepted, these objections point out certain obscurities and flaws in Kant’s argument, casting doubt, from a logical standpoint, on the success of the main Kantian criticism of the cosmological proof.
Achtung in Kant and Smith
Authors: Walschots Michael 
Published: June 2022

Abstract
This paper argues that Kant’s concept of ‘respect’ (Achtung) for the moral law has roots in Adam Smith’s concept of ‘regard’ for the general rules of conduct, which was translated as Achtung in the first German translation of the Theory of Moral Sentiments. After illustrating that Kant’s technical understanding of respect appeared relatively late in his intellectual development, I argue that Kant’s concept of respect and Smith’s concept of regard share a basic similarity: they are both a single complex phenomenon with two core aspects, namely an attitude and a feeling. I then suggest that the concept of regard offered Kant a way to deal a problem concerning moral motivation that he was trying to solve at the time he likely first read Smith. I conclude by drawing some implications from the account I have offered for our understanding of Kant’s relation to Smith more generally.
Der „erste Satz“ in Grundlegung I
Authors: Steigleder Klaus 
Published: June 2022

Abstract
In this article, I try to show that the question of what the “first proposition” in Groundwork I is can be answered by textual evidence. At the end of paragraph 15 of GMS I, Kant recapitulates the “first proposition”. It is: “Eine Handlung aus Pflicht sondert den Einfluss der Neigung ganz ab.“ (“An action from duty puts aside entirely the influence of inclination.”). It is also shown that this “proposition” summarizes an important result of Kant’s argument in the preceding paragraphs 8–13 and is presupposed by the “second proposition” and by Kant’s whole argument in the paragraphs 14 and 15, which he recapitulates in the last sentence of paragraph 15.

n

(1), (cyipH2 = 5-(3-carboxybenzyloxy)-isophthalic acid, bpe = 1,2-bis(4-pyridyl)ethane), has been synthesized under hydrothermal conditions. Its structure was determined by single-crystal X-ray diffraction analysis and further characterized by elemental analysis and IR spectra. Complex 1 crystallizes in the monoclinic space group I2/a. In 1, the [cyip]2– ligand bridges the Zn(II) cations to form infinite chains, which are connected through O–H···O hydrogen bonds into layers in the form of 2-fold interpenetrated nets.
Managerhaftung auf Kartellschadensersatz
Authors: Otto Jannik 
Published: June 2022

Zusammenfassung
Im Fokus kartellschadensersatzrechtlicher Klagen stehen die kartellbeteiligten Unternehmen. Dieser Beitrag beleuchtet hingegen die kartellzivilrechtliche Haftung der handelnden natürlichen Personen. Auch wenn diese in wirtschaftlicher Hinsicht in den allermeisten Fällen hinter der Haftung der kartellbeteiligten Unternehmen zurücksteht, kann ihr gleichwohl taktische Bedeutung zukommen, etwa in Vergleichsverhandlungen, insbesondere wenn die handelnden Personen noch im Unternehmen sind. Im Gesamtgefüge kartellzivilrechtlicher Haftung kann die persönliche Außenhaftung einen Beitrag leisten zu einer Verhaltenssteuerung, die unmittelbar auf der persönlichen Ebene ansetzt. In dogmatischer Hinsicht ist das Verhältnis zur persönlichen Bußgeldverantwortlichkeit interessant. Dieser Beitrag entwickelt einen Ansatz, der eine durchaus weitgehende persönliche Außenhaftung von Leitungspersonen im geltenden Recht begründet, die gleichwohl aus allgemeinen haftungsrechtlichen Gründen hinter der persönlichen Bußgeldverantwortlichkeit und auch in Bezug auf Beseitigungs- und Unterlassungsansprüche hinter dem gegen das Unternehmen gerichteten Anspruch zurückbleibt.
Über private Selbstregulierung, Verbandsprivilegien und die Rechtfertigung von Wettbewerbsbeschränkungen durch nicht-wirtschaftliche Ziele
Authors: Wimmer Alexander 
Published: June 2022

Zusammenfassung
Das vom Unionskartellrecht intendierte Wettbewerbsprinzip ist als Funktionsvoraussetzung der Privatautonomie der Marktteilnehmer von zentraler Bedeutung für die Privatrechtsgesellschaft. Dieser Aspekt zeigt sich auch in den rechtlichen Erwägungen im jüngst ergangenen ISU-Urteil des EuG. Die Entscheidung verdeutlicht ebenso, dass im Rahmen des Unionskartellrecht nicht nur ökonomische Effizienzaspekte als Rechtfertigung für potenziell wettbewerbsbeschränkende Verhaltensweisen von Unternehmen berücksichtigt werden können. Der vorliegende Beitrag will nach Analyse dieser Gesichtspunkte des Urteils, überlegen inwiefern sich die Begründungslinien auf andere (aktuelle) Konstellationen innerhalb der Privatrechtsgesellschaft übertragen lassen.

Aim. To assess the association of vitamin D deficiency with hormonal and metabolic disorders, including with insulin resistance and leptin levels, in patients with metabolic syndrome (MS) and chronic kidney disease (CKD).Material and methods. The study included 81 patients with MS and CKD aged 45-59 years (mean age, 51±4 years). Depending on vitamin D level, the patients were divided into two groups: group 1 (n=49) — patients with reduced level (23,2±5,1 ng/ml); group 2 (n=32) — patients with an adequate level (54,8±12,1 ng/ml). Statistical processing was carried out using STATISTICA 10.0 software.Results. In patients of the first group, the following parameters were higher than in the second one: waist circumference by 9,0% (p<0,05), waist-to-hip ratio by 8,2% (p<0,05), body mass index by 15,1% (p<0,05). The groups did not differ significantly in systolic and diastolic blood pressure levels. In the first group, the level of total cholesterol by 18,6% (p<0,01), low density lipoprotein cholesterol by 11,9% (p<0,05), triglycerides by 20,8% (p<0,01), Homeostasis Model Assessment Insulin Resistance (HOMA-IR) by 42,5% (p<0,001), leptin by 30,5% (p<0,01) were higher than in the second group. More severe left ventricular diastolic dysfunction in the first group than in the second one was determined as follows: lower left ventricular early to late filling (E/A) by 13,2% (p<0,05) and deceleration time of the early transmitral flow velocity by 13,1% (p<0,05).Conclusion. The results obtained indicate that patients with MS, CKD and vitamin D deficiency are more likely to have general obesity, more pronounced carbohydrate (HOMA-IR index) and fat (levels of total cholesterol, low-density lipoprotein cholesterol, triglycerides) metabolism disorders, as well as high serum levels of leptin compared with patients with adequate levels of this vitamin.

Published: June 2022

Amid a global rush for vaccines, Indonesia has had to compete with other countries to secure vaccines to protect its people from the infection of COVID-19. For its survival, Indonesia's vaccine diplomacy deemed it necessary to remain strategically neutral to prevent Indonesia from being one side of global power. The question in this research is how Indonesia’s effort to procure COVID-19 vaccine while maintaining ‘Free and Active’ foreign policy in bilateral, regional and multilateral and why ‘Free and Active’ foreign policy became important for Indonesia in conducting vaccine diplomacy. The study's aims to examine Indonesia's effort to procure COVID-19 vaccine while maintaining free and active principles and analyze the importance of free and active vaccine diplomacy to ensure the country's independence. This study uses qualitative study methods in research design with data collection techniques from primary (official reports and government records) and secondary data (books, journals, and online media). The research shows Indonesia's effort to procure the COVID-19 vaccine in three ways, namely bilateral (Australia, China, Russia, UK, and the US), regional (ASEAN and IORA), and multilateral (UN and Covax-AMC EG) cooperation with six types of vaccines has secure in Indonesia. China readily supported Indonesia in turning into a vaccine manufacturing hub for Southeast Asia. In this regard, the pandemic would possibly, facilitate Jakarta's nearer ties with Beijing. Thus, free and active foreign policy becomes important for Indonesia in vaccine diplomacy because it balances the national interest.
