Published: September 2019

Introduction: Varicoceles account for the most common correctable cause of male infertility, with varicocele repair leading to improvements in semen quality. However, there is little evidence to establish the durability of varicocele repair. We analyzed the durability of improvements in postoperative semen parameters following microsurgical subinguinal varicocele repair.
Methods: We evaluated all men who underwent microscopic subinguinal varicocelectomy from 2015‒2019. Patients were included if they desired fertility and had a followup of at least 12 months. We assessed the baseline characteristics of these patients, as well as semen volume, total motile sperm count (TMSC), concentration, percent motility, and morphology. Semen parameters were analyzed at baseline (preoperative), approximately three months and ≥12 months postoperatively.
Results: Of 105 men who underwent varicocelectomy, 18 men had a followup of at least 12 months. These men presented with median age 34.5 (27–38] years for a median followup duration of 14.5 (13–22.5) months. TMSC levels increased from 6.4 (1.1–24.5) million at baseline to 11.1 (2.4–38.4) million at approximately three months and remained similar at 12.5 (1.6–31.5) million at ≥12 months. The study is limited by its retrospective nature and limited sample size.
Conclusions: Microscopic subinguinal varicocele repairs can result in durable improvements of semen quality beyond one year, as demonstrated by upgrade in median TMSC. Further studies should be performed to confirm our findings.
Descartes on the Highest Good
Authors: Svensson Frans ,   Philosophy Documentation Center
Published: September 2019

What is the highest good? In the ethics of René Descartes, we can distinguish between at least seven different answers to this question: (a) God; (b) the sum of all the different goods that “we either possess . . . or have the power to acquire” (CSMK, 324/AT 5, 82); (c) free will; (d) virtue; (e) love of God; (f) wisdom; and (g) supernatural beatitude. In this paper, I argue that each of these answers, in Descartes’s view, provides the correct particular conception, relative to a distinct sense or concept of the highest good. Just as there are seven different conceptions of the highest good, according to Descartes, there are thus also seven different senses or concepts of the highest good.
Du « capital culturel » au savoir
Authors: Glevarec Hervé 
Published: September 2019

Introduit par P. Bourdieu et J.-C. Passeron dans les années 1960, le terme capital, appliqué à la culture, est devenu une notion d’usage courant en sociologie. Il représente la conceptualisation, d’une part, du facteur explicatif de la reproduction sociale, par l’école, et, d’autre part, de la distribution sociale des goûts et des pratiques culturelles et, enfin, d’une dimension de l’être des individus (un des fondements, avec le « capital économique », de l’habitus). La notion se veut critique par sa considération des usages et fonctions sociales de la culture, son fonctionnement dans une relation de domination. Le capital culturel est censé prendre son contenu sociologique, selon P. Bourdieu, en relation au concept de « champ », soit sa définition proprement relationnelle. Cet article s’attache à montrer la signification universelle que cette notion a prise et qui se traduit dorénavant par un usage générique, une indistinction des dimensions de domination et de cognition et un emploi au-delà du processus de socialisation initialement à son fondement. C’est le statut épistémologique de l’analogie en sociologie qui est examiné. Nous soutenons que la notion de capital culturel devrait être réservée à la description des usages sociaux de la culture dans un rapport social arbitraire et être remplacée par celle de savoirs, déclinés au pluriel, chaque fois qu’il s’agit de désigner une connaissance ou une compétence pratique adéquate à son objet dans une situation qui le requiert.
Os limites da percepção interna e a idolatria do autoconhecimento em Scheler
Authors: Ramos Daniel Rodrigues 
Published: September 2019

O artigo pretende discutir a possiblidade da percepção interna, delimitando-a do compreender da pessoa, que pode ser tanto compreensão do próximo como autocompreensão. Do mesmo modo, a percepção interna poder ser a percepção de si mesmo como percepção do outro. Parte-se, portanto, de uma indicação recorrente na fenomenologia de Scheler, de acordo com a qual a percepção interna não pode ser reduzida à autopercepção, entendida, sobretudo, no sentido de autoconsciência. Nesta direção, primeiramente, tenta-se uma definição fenomenológica do ato em questão, visando, sobretudo, libertá-lo das determinações idealistas enquanto autoconsciência e das compreensões subjetivistas, tais como a auto-observação e meio de autoconhecimento. Para tanto, demonstra-se que a percepção interna é uma direção de um único ato perceptivo e que o seu objeto não é uma forma lógica pura e vazia, mas sim a apreensão do eu material, concreto e singular. A intuição imediata e direta deste eu, então, aparecerá como a base sobre a qual se rompe com as duas interpretações supracitadas. Por fim, discute-se os elementos internos que contribuem para estes limites, em especial a fisiologia do sentido interno e os interesses do corpo-próprio (Leib), o que permite entender positivamente os limites e descrever os seus primeiros significados. A partir deste ganho fenomenológico, a investigação detém-se nos fatores externos, responsáveis por transformar a percepção interna em mero instrumento do autoconhecimento e por subjugá-la às metas e interpretações da cosmovisão natural, analisando brevemente as fontes da idolatria do autoconhecimento. Conclui-se que, na delimitação de sua possibilidade essencial, a desconsideração do papel psicofisiológico do sentido interno, a transladação das leis e relações espaço-temporais próprias da esfera física para a psíquica e, consequentemente, a superposição da percepção externa sobre a interna em consonância com a interpretação sensualista da última são as principais fontes da ilusão denominada idolatria do autoconhecimento.

Aim: The aim of this study is to assess fermented parkia infusion in feed as organic strategy to improve feed quality and immune system of African catfish (Clarias gariepinus) fingerlings.
Place and Duration of Study: Department of Biochemistry, Ibrahim Badamasi Babangida University, Lapai, Niger State, Nigeria, between 1st January 2017 and 25th March 2017.
Methodology: In the present study, feed ingredients were fermented for 72 hrs with probiotic starter culture from Parkia biglobosa (TF diet) in comparison to a control diet with similar ingredients to the experimental diets but totally unfermented (CF diet) and used to make feed pellets. The experimental feeds were fed at 5% of body weight of each dietary treatment to triplicate groups of 20 fish per tank (100 Liter capacity), two times daily for 10 weeks. Proximate composition and mineral content of diets and whole fish, Feed efficiency, growth performance and Biochemical parameters of the fish were evaluated.
Results: The result of proximate compositions of experimental diets revealed a significantly higher protein and ash contents in TF compared to the CF. Carbohydrate content was significantly lower in TF diet while crude fibre, moisture and fat contents were not significantly higher in CF compared to TF. The highest values of some minerals such as sodium (Na), potassium (K), phosphorus (P) and magnesium (Mg) were also recorded in the TF while the least was recorded in CF. The result of feed efficiency and growth performance indicated similar feed acceptance and intake between fish fed the fermented diet and the control. The activities of serum antioxidant enzymes activities of superoxide dismutase and catalase were significantly (P < 0.05) higher in serum of fish fed TF compared to that in fish fed CF diet.
Conclusion: It can be deduced from this study that the fermented diet improved the immunity of fish and does not adversely affect the growth performance.

Multi-junction photovoltaic cells composed of III-V semiconductor materials are widely used in photovoltaic systems. They offer very high efficiencies compared to single-junction photovoltaic cells. Knowledge of the behavior of their electrical parameters in real operating conditions is essential for their best use. This work presents an analytical model for predicting the behavior of the output electrical parameters of the sub-cells composing the Ga0.67In0.33P/GaAs/Ga0.70In0.30As triple junction photovoltaic cell, operating under the actual conditions of two selected sites. The dependence of the external quantum efficiency at the wavelengths corresponding to the absorption ranges of the top (Ga0.67In0.33P), middle (GaAs) and bottom (Ga0.70In0.30As)$$ sub-cells is analyzed and discussed. The influence of temperature and irradiation on the V oc ,J sc, F F and η parameters is discussed taking into account the meteorological characteristics of two selected locations. An average daily conversion efficiency of the Triple-Junction solar cell of 37.24% and a daily electrical power of 1613.1 W/m2 for the typical day(TD) of the sunniest month of the Bujumbura site were found. Similarly, under the same conditions, for the Bugarama site, we found an average daily efficiency of 37.28% and a daily electrical power of 1619.7 W/m2. The developed model can also be used to design a more suitable Photovoltaic system at any specified place, provided that local weather data is available.

ImportanceHypertension is a risk factor for the development and progression of chronic kidney disease (CKD). It is unclear whether different thiazide diuretics have a differential impact on kidney outcomes.ObjectiveTo compare kidney outcomes in patients with hypertension taking chlorthalidone and hydrochlorothiazide.Design, Setting, and ParticipantsThis prespecified secondary analysis of the Diuretic Comparison Project, a randomized clinical trial comparing chlorthalidone and hydrochlorothiazide for the treatment of hypertension, was conducted between June 1, 2016, and June 1, 2022, through Veterans Affairs facilities nationwide. This analysis extended follow-up to December 31, 2023. Veterans 65 years or older with hypertension who were taking hydrochlorothiazide were included.InterventionThe Diuretic Comparison Project randomized 13 523 participants to continue hydrochlorothiazide or switch to chlorthalidone.Main Outcome and MeasuresThe main kidney outcome was CKD progression, defined as doubling of serum creatinine level from baseline, a terminal estimated glomerular filtration rate (eGFR) less than 15 mL/min, or dialysis initiation.ResultsAnalysis included 12 265 participants (90.7%) with a baseline and 1 or more follow-up creatinine measurements (median [IQR] age, 71 [69-75] years; 3.2% female and 96.8% male). The mean (SD) study duration was 3.9 (1.3) years. Chlorthalidone was not superior to hydrochlorothiazide at preventing kidney outcomes (369 of 6118 [6.0%] vs 396 of 6147 [6.4%]; hazard ratio [HR], 0.94; 95% CI, 0.81-1.08; P = .37). Similar results were observed when a 40% or greater reduction of eGFR was substituted for doubling of creatinine in the above outcome, as well as any of the components of the primary composite outcome. There was no difference in the incidence of CKD (961 of 4520 [21.3%] for chlorthalidone vs 939 of 4518 [20.8%] for hydrochlorothiazide; P = .59) or acute kidney injury requiring hospitalization (391 [6.4%] for chlorthalidone vs 379 [6.2%] for hydrochlorothiazide; P = .63) between groups. However, a statistically significant increased incidence of hypokalemia for chlorthalidone vs hydrochlorothiazide was observed (545 [8.9%] vs 426 [6.9%]; P &amp;lt; .001).Conclusions and RelevanceChlorthalidone was not superior to hydrochlorothiazide for kidney outcomes but was associated with an increased risk for hypokalemia. Given these findings, clinicians should feel confident using either agent for the treatment of hypertension and kidney outcomes.Trial RegistrationClinicalTrials.gov Identifier: NCT02185417

Published: December 2024

AbstractHybrid and heterostructures exhibit intriguing and significant properties that can endow unique properties to high‐performance batteries. However, their applications are often hampered by limited structural stability due to inevitable material agglomeration and structural collapse during repeated electrochemical cycles. Here, an efficient strategy to utilize an intermediate nanoglue to bond the substrate and heterojunction phase and increase the overall structural stability is reported. After screening the possible Fe‐based oxides, tunnel‐type FeOOH satisfies the principle of relatively high affinity to both Ti3C2Ox support and Fe3O4 phase, thus strengthening heterostructure stability. Furthermore, functional FeOOH quantum dots as nanoglue and graft them onto high‐surface‐area Ti3C2Ox support is experimentally utilized, then load high‐capacity Fe3O4 nanoparticles onto the nanoglue. The designed heterostructured nanoglue not only yields abundant heterojunctions with continuous channels for ion/electron transfer but maintains excellent electrochemical reversibility. Serving as anode for lithium storage, Ti3C2Ox/FeOOH/Fe3O4 hybrid enables a high discharging capacity of 790.4 mAh g−1 at 1.0 A g−1 after 500 cycles and superior cycling stability. The design principle is general and can be expanded to other hybrid materials.

AbstractAmmonia, with high hydrogen content and carbon neutrality, is an ideal fuel for protonic ceramic fuel cells (PCFCs). However, the limited electrochemical efficiency and durability of ammonia‐based PCFCs have posed challenges for broader implementation. Herein, a novel anode material, Ni‐Ba(Zr0.1Ce0.7Y0.1Yb0.1)0.94Ru0.03Fe0.03O3‐δ (BZCYYbRF), developed by co‐doping with Ru and Fe is introduced, which promotes the exsolution of RuFe nanoparticles under reducing conditions. A secondary redox process further enhances nanoparticle redistribution, increasing catalytic activity and improving ammonia decomposition and hydrogen oxidation, as well as the charge transfer at the heterointerface, leading to a marked improvement in the electrochemical performance of the PCFC under both hydrogen and ammonia fuel conditions. A single cell utilizing BZCYYbRF as the anode achieves a peak power density of 700 mW cm⁻2 at 650 °C under NH3 fuel, with stable operation for up to 150 h. Additionally, secondary redox treatment improved performance to 807 mW cm⁻2 at 650 °C. The innovation lies in the co‐doping and redox‐driven nanoparticle exsolution strategy, significantly boosting PCFC performance and stability, positioning this anode as a breakthrough for direct ammonia fuel cells.

AbstractThe global energy crisis and environmental concerns are driving research into renewable energy and sustainable energy conversion and storage technologies. Solar energy, as an ideal sustainable resource, has significant potential to contribute to the goal of net‐zero carbon emissions if effectively harnessed and converted into a reliable and storable form of energy. Photocatalysts have the potential to convert sunlight into chemical energy carriers. In this respect, covalent organic frameworks (COFs) have shown great promise due to their tunable structure on different length scales, high surface areas, and beneficial optical properties such as broad visible light absorption. This review offers a comprehensive overview of the key developments in COF‐based photocatalysts for various applications, including water splitting, hydrogen peroxide generation, organic transformations, and carbon dioxide and nitrogen reduction. The underlying mechanisms, essential principles for material design, and structure‐function relationships of COFs in various photocatalytic applications are discussed. The challenges faced by COF‐based photocatalysts are also summarized and various strategies to enhance their performance are explained, such as improving crystallinity, regulating molecular structures, tailoring linkages, and incorporating cocatalysts. Finally, critical strategies are proposed for the utilization of photocatalytically generated chemicals into value‐added products.

Published: December 2024

AbstractAdditive manufacturing is critical in modern production with advanced applications across various domains. However, achieving omnidirectional printing that can adapt to varying substrate geometries is still a challenge. Moreover, multi‐material in situ printing without cross‐contamination presents another hurdle. In this study, an acoustophoretic 3D fabrication system capable of omnidirectional and multi‐material in situ 3D printing is reported using acoustic levitation. This system harnesses a phased array of transducers (PAT) to finely tune the ultrasonic field, generating acoustophoretic forces that levitate and transport objects in mid‐air. It allows omnidirectional in situ printing of materials onto complex substrates with diverse orientations in a contactless and voxel‐by‐voxel manner. It is capable of manipulating a broad spectrum of materials, including liquids with zero‐shear viscosities from 1 to 5,000,000 mPa·s, as well as solids. AcoustoFab has successfully printed structural, conductive, and biological materials in varying directions on complex substrates. Additionally, the contactless approach enables in situ printing safely on a delicate surface, as demonstrated by printing on a human hand. The flexibility and versatility of this approach demonstrate promising applications in areas ranging from biomedical engineering to industrial manufacturing.

AbstractHydrogen sulfide (H2S) serves as the third gasotransmitter, crucial in various physiological processes involving its production and metabolism. Elevated levels of H2S can result in acute or chronic poisoning, whereas lower concentrations are involved in regulating diverse physiological and pathological activities within the human body. Moreover, it actively participates in maintaining normal cellular function by exerting cell protection and anti‐apoptotic effects. In recent years, extensive research has been conducted to explore the physiological significance of H2S and its potential applications in developing prodrugs. To further unravel the biological and clinical potential of H2S, H2S donors have gained widespread utilization. These compounds facilitate our understanding of the specific functional aspects governed by H2S and hold promise as potential therapeutic agents. Therefore, it is necessary to study H2S as a delivery vehicle at the cellular and in vivo levels. This review provides an overview of advancements made over the past five years regarding H2S donors and their applications in biology, encompassing indirectly released donors of carbonyl sulfide (COS), directly released small molecule donors, Nanocomposite scaffolds, and hydrogels.

ABSTRACTAnabolic–androgenic steroids (AAS) are banned substances in both human and equine sports. They are often administered intramuscularly to horses in esterified forms for the purpose of extending their duration of action. As such, the detection of intact esters of endogenous steroids in hair is particularly advantageous, as it can provide unequivocal proof of their external origin. Compared with urine and blood matrices, hair in general allows a longer detection window as long as the administered drug can be incorporated into hair and has not degraded. This can be useful in doping control of equine sports, where the timing of sample collection may be critical due to the transient nature of AAS in other biological fluids. This paper describes the detection of AAS and/or their esters, as well as corticosteroids, in horse hair using ultra‐high‐performance liquid chromatography–high‐resolution mass spectrometry (UPLC‐HRMS) and gas chromatography–tandem mass spectrometry (GC‐MS/MS) after solid‐supported liquid extraction (SLE) at basic pH. The developed UPLC‐HRMS and GC‐MS/MS methods in combination allowed the detection of 117 AAS, corticosteroids and/or their esters with estimated limits of detection down to sub‐ppb levels and with good inter‐day precision. Method applicability has been demonstrated through the detections of (i) boldenone undecylenate, nandrolone phenylpropionate and trenbolone acetate in three proficiency testing hair samples and (ii) nandrolone as a metabolite in a post‐administration hair sample collected from a castrated horse having been administered nandrolone decanoate.
