Revisiting Pauline Oliveros
Authors: Quaranta Daniel Eduardo , David Pedro Leal
Published: June 2024

In this article, two forms of dialogue are proposed: one is direct, in the form of an exclusive interview with the composer Pauline Oliveros, conducted shortly before her death and rediscovered on an old hard drive. From this material the second dialogue emerges, an essay that attempts to construct a network of resonances between Oliveros’s thought and work and that of other authors such as Pierre Schaeffer, Michel Chion, Denis Smalley, and R. Murray Schafer. The limitless world of sonic possibilities introduced by contemporary and electroacoustic music since the second half of the last century is closely linked to extensive reflection on listening. Pauline Oliveros is one of the pioneers and most significant composers to contemplate this issue. Her ideas, conveyed through works, meditative practices, interviews, and texts, provide substantial material for examining the listening relationships that humans establish or can establish with the world around them.

Flemingia macrophylla has traditionally been applied to relieve inflammation, diabetes, and circulatory complications. The leaf extract of F. macrophylla and its fractions were investigated for their in-vitro antioxidant and anti-diabetic properties. The phytochemical screening showed valuable phytochemicals, including glycosides, flavonoids, saponins, etc. GC‒MS analysis of the phytochemicals in the methanol extract detected 19 bioactive compounds. Among the diverse fractions, the ethyl acetate fraction (EFM) exhibited the highest phenol and flavonoid contents of 557 mg GAE/g and 326 mg QCE/g, respectively. The total antioxidant content of EFM was found to be 292.41±19.16 mg AAE/g, while its antidiabetic study showed the greatest level of α -glucosidase (IC50: 11.27±1.25 µg/mL) and α -amylase (IC50: 10.04±0.63 µg/mL) inhibitory effects. The docking results showed that C6 had the highest binding scores of -9.0, -7.4, and -7.6 kcal/mol against antioxidant (6NGJ), α-glucosidase (5NN5), and α-amylase (4GQR) proteins, respectively. The dynamics simulation disclosed that C6-receptor protein complexes remained stable at the binding pocket under human body conditions and retained their stiff morphology for 100 nanoseconds (ns). ADMET results demonstrated their noncarcinogenic and well-absorbed properties, where PASS prediction data confirmed their efficacy as an antioxidant, antiulcerative, thrombolytic, and antidiabetic. Therefore, F. macrophylla has potential health benefits.

В історичному аспекті представлено аналіз досліджень генетичного різноманіття лісотвірних деревних видів. В їх розвитку виділено чотири важливих напрями: еколого-географічний; фенотипічний з відбором кращих плюс-варіантів; генетико-популяційний; морфолого-фізіологічний.
Запровадження цих напрямів у практику лісового господарства здійснюється на основі як традиційних, так і новітніх підходів до селекційної оцінки деревних рослин. Традиційні способи ідентифікації дерев базуються на використанні різноманітних морфолого-анатомічних, фізіологічних і біохімічних показників дерев. До нетрадиційних підходів відносять використання показників вмісту терпенових вуглеводнів, ізоферментний аналіз, дослідження генетичної мінливості рослин на рівні ДНК.       
На сьогодні бурхливо розвивається новий науковий напрям генетичних досліджень – геноміка, яка дає змогу отримати важливу генетичну інформацію і розробити високоінформативні молекурно-генетичні маркери – мікросателіти та однонуклеотидні поліморфізми. Вони можуть бути ефективно використані для вивчення генетичної мінливості лісів, їх адаптації до зміни клімату, для створення селекційних програм. До останніх досягнень в області лісової геноміки відносять повногеномне секвенування, збірку та анотування геномів Picea abies (L.) Karst., Picea glauca Voss., Pinus taeda L., Pinus sylvestris L., Larix sibirica Ledeb., Pinus sibirica Du Tour. та інших видів хвойних.
Водночас, поряд з методами біохімічної генетики, а також традиційними способами досліджень, необхідні нові підходи до вирішення генетико-селекційних задач у лісовому господарстві, які враховують тривалість онтогенезу деревних видів, вікові зміни у їхньому розвитку, механізми реалізації генотипу в конкретних умовах середовища.

Northern part of Bekasi Regency (Pantura Bekasi) has diverse land: a port area, fisheries, marine tourism, agriculture, residential, industrial and government. Various types of development are occured to support the  community welfare. Developments occur without considering sustainability will result in a decline of environmental conditions, and each region will have its own ability to anticipate the impacts of changes that occurs. This research studied coastal vulnerability in the Pantura Bekasi and the relationship between their coastal physical parameters and the vulnerability. Field observations were also conducted as field validation and perceive current conditions. The results show that vulnerability is very high in Fishery port (PPI) Muara Jaya port zone (Mekar Coast), and low vulnerability occurred in Taruma Jaya port zone (Taruma Jaya Coast). Two paramaters are different in these two locations, they are coastline change and geomorphological. The coastline change at Mekar Coast is abrasion, and Taruma Jaya Coast is accretion. The geomorphological at Mekar Coast are a muddy beach and delta, while Taruma Jaya Coast is a swampy beach. Field conditions show that Mekar Coast has low mangrove density, while Taruma Jaya Coast has high mangrove density. These results hopefully can be used as policy consideration for the local government in optimizing coastal management planning, where the spatial plan for Pantai Mekar Beach is designated as a conservation area and demersal fisheries, while on Pantai Taruma Jaya as a public use area such as for Gas and Steam Power Plant (PLTGU) Muara Tawar, PPI Paljaya and port zone.

Published: June 2024

Cryopreservation is an effective method for long-term storage of sperm. It is essential to investigate the optimal conditions for preserving semen for the purpose of artificial insemination. Cysteine has been proven to reduce the extent of sperm damage caused by oxidative stress during cryopreservation. The aim of this study was to determine the concentration of cysteine required for cryopreservation of goat semen. The experiment was carried out on 2 bucks with 4 treatments, each treatment repeated 8 times. Goat semen was diluted with cryopreservation medium supplemented with cysteine at 4 concentrations: 0 mM, 2 mM, 5 mM, and 10 mM. The sample was transferred to a straw at 0.5 mL, then stored in a liquid nitrogen container. The samples were then thawed, and the sperm quality was evaluated after 72 hours of storage. The results showed that the treatment with 5 mM cysteine showed the best sperm quality results, and the difference was statistically significant with the rest of the treatments (P < 0.05). Specifically, the overall motility, viability, and membrane integrity of spermatozoa in the most optimal treatment were: 82.21%, 90.71%, and 76.09%, respectively. In summary, the study showed that adding a 5 mM concentration of cysteine to the cryopreservation medium significantly enhanced sperm quality

Published: June 2024

This article presents an exploratory study that examines how 11 first-year writing instructors’ conceptualizations of information literacy evolved over the course of their participation in an inquiry group co-developed and co-facilitated by the Libraries’ teaching faculty and the Director of Composition & Rhetoric at a public university in the United States. The authors developed a coding schema to identify the presence of information literacy-related themes and practices in pre- and post-program course syllabi and in reflective pieces submitted by instructors. The findings revealed that instructors’ use and applications of the ACRL Framework increased after the program, showing greater personal engagement as evidenced by more preferential application of frames most relevant to their learning goals. Moreover, instructors integrated those frames more fully into their instructional practices. The authors’ analysis of instructor-created artifacts provides a unique lens into disciplinary instructors’ conceptualizations of and approaches to information literacy while examining the impact of one path for collaboration and scalability of information literacy integration within a curriculum.

Published: June 2024

Abstract Studies regarding cytotoxic effects attributed to the use of adhesive bonding agents on pulp tissue are not conclusive. To point out whether these materials are safe for clinical use, in vivo exposure of dental pulp to adhesive bonding agents was simulated using an experimental setup in which Human Dental Pulp Stem Cells (hDPSC) are exposed to the action of two kinds of adhesives: self-etching adhesives and two-step bonding agents through a dentine barrier. Cytotoxic effects on these cells were evaluated by MTT assay protocol and fluorescence microscopy, and their results were contrasted to those obtained through Raman spectra taken on single hDPSCs. Overall, no significant cytotoxic effects were observed by combining all the techniques, and cell viability close to 90% was achieved for a dentine barrier of at least 1 mm thick. Moreover, Raman spectroscopy was able to detect structural DNA damage in some dental pulp cells when exposed to two-step bonding agents, suggesting that this technique could be considered a complementary tool with the potential to evaluate cell toxicity beyond cell viability.

Published: June 2024

Abstract Rehabilitation of edentulous atrophic mandibles involves the placement of implants in the anterior segment of the mandible. The primary stability of these implants can be improved using the base of the mandible as complementary anchorage (bicorticalization). This study aimed to analyze the biomechanics of atrophic mandibles rehabilitated with monocortical or bicortical implants. Two three-dimensional virtual models of edentulous mandibles with severe atrophy were prepared. Four monocortical implants were placed in one model (McMM), and four bicortical implants were placed in the other (BcMM). An implant-supported total prosthesis was prepared for each model. Then, a total axial load of 600 N was applied to the posterior teeth, and its effects on the models were analyzed using finite element analysis. The highest compressive stresses were concentrated in the cervical region of the implants in the McMM (-32.562 Mpa); in the BcMM, compressive stresses were distributed in the upper and lower cortex of the mandible, with increased compressive stresses at the distal implants (-63.792 Mpa). Thus, we conclude that axial loading forces are more uniformly distributed in the peri-implant bone when using monocortical implants and concentrated in the apical and cervical regions of the peri-implant bone when using bicortical implants.

ABSTRACT Objective: Assess complications and risks in staged femoral shaft fracture treatment using external fixation and intramedullary nailing (DCO). Methods: Analysis involved 37 patients with 40 fractures, mostly male (87.5%), average age 32.9 years. Data included ASA score, AO/OTA and Gustilo classifications, Glasgow Coma Score, Injury Severity Score, times to external fixation and conversion, ICU duration, nail type, and reaming status. Complications tracked were mortality, deep infection, and non-union. Results: Predominant fracture type was AO/OTA A (45%), with 40% open (Gustilo A, 93.8%). Average ISS was 21; GCS was 12.7. Median ICU stay was 3 days; average time to conversion was 10.2 days. Retrograde nails were used in 50% of cases, with reaming in 67.5%. Complications included deep infections in 5% and non-union in 2.5%. Conclusion: DCO strategy resulted in low infection and non-union rates, associated with lower GCS and longer ICU stays.

Published: June 2024

Abstract Global biodiversity is under substantial threat due to biological invasions, a problem exacerbated by climate change. Such invasions have detrimental effects on the environment, economy, and human health, resulting in significant financial burdens. Recently, understanding these challenges has become a highlighted priority within the scientific community. This study focuses on the evaluation of Schinus terebinthifolia, native to South America, and its invasive spread into North and Central America, which has resulted in wide distribution and considerable impact. The primary objectives of this study include analyzing the potential distribution of the species under current and future climate scenarios, identifying the areas where its climatic niche is changing. Data collection encompassed a vast dataset of over 30,000 occurrence records of this species, from the following databases: (1) The Global Biodiversity Information Facility provided 22,163 records (GBIF), (2) The virtual Herbarium Reflora contributed 1,438 records, and NeoTropTree made available 6,591 records. Following a rigorous filtering process, 992 occurrences were considered for modeling. In this process, we utilized climate data and climate projections, employing various algorithms, with an emphasis on the consensus model methodology. The research results reveal a clear trend of reduced habitat suitability for S. terebinthifolia, especially under scenarios of high global warming. This accentuates the urgency of implementing emission control measures and mitigation strategies. Additionally, the study underscores the crucial importance of continuous monitoring, as well as actions for controlling and restoring affected ecosystems. The significant role played by S. terebinthifolia in both its native and invaded areas highlights the need for comprehensive management approaches. In the face of climate change and biodiversity threats, this study provides insightful observations on the dynamics of biological invasions. Success in addressing these issues relies on close cooperation between the scientific community, policymakers, land managers, and local communities. This collaboration is essential for guiding and conducting conservation and biodiversity management efforts in an ever-evolving world.

ABSTRACT Ophidic accidents caused by snakes of the genus Bothrops are responsible for 70% of notifications in the country. The antiophidic serum is the specific antidote against envenomation caused by these snakes. Aiming to evaluate the health status of horses producing antibotropic serum, the hematological variables and serum iron were delineated along the protocol of three immunizations. The animals were evaluated at 17 experimental moments, being: control (before the immunogen application), four hours, 24h, 48h, 72h and seven days after inoculations, for each immunization. There was a significant decrease in erythrocyte, hemoglobin, and hematocrit values after the second immunization. Serum iron values showed significant decreases during the three immunizations. Significant decreases in lymphocyte values were noted in the first two immunizations, while there was a significant increase in neutrophil values during all three immunizations. Eosinophils, monocytes, and basophils did not show significant difference throughout the three immunizations. The immunization protocol described in this study caused an inflammatory reaction at the site of immunogen application and transient changes in hematological parameters and iron levels, as by the end of the immunization protocol, the variable values returned the reference levels.

Published: June 2024

ABSTRACT Insects of the Ephemeroptera order have been used as bioindicators of water quality as they respond to countless anthropic impacts. In this study, we assessed the use of Ephemeroptera as bioindicators of streams impacted by agricultural activities. We collected Ephemeroptera nymphs in six streams with different uses and soil cover in their drainage areas located in the northern region of the Brazilian state of Rio Grande do Sul. Based on soil use and cover analysis, we categorized the streams as ‘natural’ (drainage area with >42% native arboreal vegetation) and ‘agricultural’ (drainage area with >72% agricultural use). We collected a total of 2,767 organisms, distributed into four families and eleven genera. We observed greater abundance (68%) and taxonomic richness (11 genera) of Ephemeroptera in the agricultural streams. The natural streams comprise 32% of the fauna collected, with eight genera. That pattern was especially determined by the Baetidae and Leptohyphidae families. The genera Caenis, Cloeodes, and Tricorythopsis were abundant in the agricultural streams. In this study, we observed that genera of Ephemeroptera are tolerant to environmental changes, particularly those caused by agricultural activities. Therefore, the use of the order in studies to assess water quality must be carried out with caution.
Can remote voting mitigate agency problems?
Authors: Marasca Letícia , Sonza Igor Bernardi
Published: June 2024

ABSTRACT Purpose: Board members are critical in resolving agency conflicts. How- ever, many are unable to perform their function due to their distance, as they are not present at board meetings. As of Instruction no. 561, the Brazilian Securities and Exchange Commission (CVM) regulated remote voting for Boards of Directors, allowing for greater attendance at meet- ings and, as a result, increased involvement. In this context, this research examines the effect of remote voting by Boards of Directors on execu- tive compensation and financial performance of publicly traded firms in Brazil. Originality/value: This research is innovative in the sense that it exam- ines the effect of the Board of Directors remote voting on the CEO com- pensation and financial performance of the firm, using an innovative methodology. Design/methodology/approach: We applied a quasi-experimental method (difference-in-differences) to assess the effects of a given group (treat- ment) before and after the event, significantly reducing endogeneity when considering an exogenous shock to the system. Findings: As a result, the estimation of the main model reveals statisti- cally significant differences between the effects of treatment and control on profitability and executive remuneration, indicating that remote vot- ing mitigated agency problems by generating a substitution effect for explicit incentives (as evidenced by the decrease in executive remunera- tion) and by providing greater accounting performance for companies.

Authors: Gaspar Natália Morais
Published: June 2024

Resumo Os dispositivos estatais para o governo das águas no Brasil vêm sendo fortemente influenciados pelo discurso do desenvolvimento, tendo como principal instituição multilateral promotora o Banco Mundial, cujas diretrizes convergem para o afastamento das instituições estatais do papel de provedoras dos serviços de água e promovem a perda do controle sobre as águas por populações locais. Neste artigo, analiso a trajetória das políticas governamentais para a gestão das águas no Brasil a partir da instituição da Política Nacional de Recursos Hídricos (PNRH) à luz da literatura antropológica sobre grandes projetos de desenvolvimento, administração pública e o campo autodenominado de antropologia da água, observando o processo de criação e implementação de dispositivos institucionais que abrem caminho para a transformação da água em uma commodity. A pesquisa foi realizada por meio de observação participante em avaliação oficial da PNRH e análise de relatórios de projetos do Banco Mundial.

ABSTRACT Objective: To analyze the relationship between the emotional intelligence of healthcare workers in a hospital environment and their perception of the safety climate in the COVID-19 pandemic. Method: Cross-sectional, analytical study, carried out with 81 health workers who worked in hospitals during the pandemic, between September and November 2021. Data collection was carried out using an electronic form, which included a sociodemographic/occupational questionnaire and the Brazilian versions of the Safety Attitudes Questionnaire and the Schutte Self Test. Spearman's correlation test and simple and multiple linear regression analyses were applied. Results: An increase of 1 point in emotional intelligence levels resulted in an increase of 0.487 points in the perception of the safety climate. The most significant predictor of this perception was the ability to manage other people’s emotions (β=0.334; p=0.003; R2=0.168). Conclusion: A higher level of emotional intelligence in hospital healthcare workers was related to a greater perception of the safety climate during the COVID-19 pandemic.

Abstract Introduction: Identifying risk factors for autosomal dominant polycystic kidney disease (ADPKD) progression is important. However, studies that have evaluated this subject using a Brazilian sample is sparce. Therefore, the aim of this study was to identify risk factors for renal outcomes and death in a Brazilian cohort of ADPKD patients. Methods: Patients had the first medical appointment between January 2002 and December 2014, and were followed up until December 2019. Associations between clinical and laboratory variables with the primary outcome (sustained decrease of at least 57% in the eGFR from baseline, need for dialysis or renal transplantation) and the secondary outcome (death from any cause) were analyzed using a multiple Cox regression model. Among 80 ADPKD patients, those under 18 years, with glomerular filtration rate <30 mL/min/1.73 m2, and/or those with missing data were excluded. There were 70 patients followed. Results: The factors independently associated with the renal outcomes were total kidney length – adjusted Hazard Ratio (HR) with a 95% confidence interval (95% CI): 1.137 (1.057–1.224), glomerular filtration rate – HR (95% CI): 0.970 (0.949–0.992), and serum uric acid level – HR (95% CI): 1.643 (1.118–2.415). Diabetes mellitus - HR (95% CI): 8.115 (1.985–33.180) and glomerular filtration rate - HR (95% CI): 0.957 (0.919–0.997) were associated with the secondary outcome. Conclusions: These findings corroborate the hypothesis that total kidney length, glomerular filtration rate and serum uric acid level may be important prognostic predictors of ADPKD in a Brazilian cohort, which could help to select patients who require closer follow up.
Tuberous Sclerosis Complex and the kidneys: what nephrologists need to know
Authors: Monich Aline Grosskopf , Bissler John J. , Barreto Fellype Carvalho
Published: June 2024

Abstract Tuberous sclerosis complex (TSC) is an autosomal dominant disease characterized by the development of hamartomas in the central nervous system, heart, skin, lungs, and kidneys and other manifestations including seizures, cortical tubers, radial migration lines, autism and cognitive disability. The disease is associated with pathogenic variants in the TSC1 or TSC2 genes, resulting in the hyperactivation of the mTOR pathway, a key regulator of cell growth and metabolism. Consequently, the hyperactivation of the mTOR pathway leads to abnormal tissue proliferation and the development of solid tumors. Kidney involvement in TSC is characterized by the development of cystic lesions, renal cell carcinoma and renal angiomyolipomas, which may progress and cause pain, bleeding, and loss of kidney function. Over the past years, there has been a notable shift in the therapeutic approach to TSC, particularly in addressing renal manifestations. mTOR inhibitors have emerged as the primary therapeutic option, whereas surgical interventions like nephrectomy and embolization being reserved primarily for complications unresponsive to clinical treatment, such as severe renal hemorrhage. This review focuses on the main clinical characteristics of TSC, the mechanisms underlying kidney involvement, the recent advances in therapy for kidney lesions, and the future perspectives.
Interoception and pediatric occupational therapy practice: a protocol for a scoping review
Authors: Clark Emma , Yu Mong-Lin , Brown Ted
Published: June 2024

Abstract Introduction Interoception is relatively new within pediatric occupational therapy practice. Interoception allows us to feel and interpret internal body sensations and is related to our ability to regulate emotions and behavior. It is associated with other functions including sensory processing, self-regulation and executive functioning, making it important for everyday participation in life activities. Pediatric occupational therapists are considering interoception as part of intervention but there is limited research to understand how and why occupational therapists use interoception in clinical practice. Objectives The aim of this protocol is to describe the methodology and analyses to be used to undertake a scoping review. Method This paper presents the protocol for a scoping review. A search of literature from ten electronic databases (Ovid Medline, Ovid Embase, Ovid PsycINFO, ERIC, Scopus, CINAHL, ProQuest Dissertations & Theses Global, AMED, OTDBASE and Google Scholar), grey literature and article reference searching was conducted. Title and abstract screening was completed before full-text review. Selected articles met stringent inclusion criteria. The PRISMA-ScR Checklist was used alongside the Crowe Critical Appraisal Tool to ensure robust data extraction and synthesis from selected studies. Results A total of 2449 articles were retrieved. Eighteen articles were included in the review. A narrative synthesis approach will be used to synthesise data. Conclusion Findings from this scoping review will inform future research related to interoception and pediatric occupational therapy practice to support clinicians to consider evidence to underpin practice.

Published: June 2024

Abstract Introduction: Due to aging, older people become more prone to dynapenia, which increases the risk of mortality. It is therefore essential to propose low-cost tools to screen for this outcome. Objective: To analyze the predictive ability of anthropometric indicators for screening dynapenia in older people. Methods: We conducted a cross-sectional census epidemiological study of 196 older people. The predictors listed were: body mass in-dex (BMI), arm circumference (AC), calf circumference (CC), arm muscle circumference and corrected arm muscle area. Student's t or Mann-Whitney U tests (comparisons) and the receiver operating characteristic curves (predictive ability) were used in the analyses. A significance level of 5% was adopted for all analyses. Results: The prevalence of dynapenia was 26.60% in older men and 24.80% in older women. It was also observed that older people with dynapenia had lower values for anthropometric indicators compared to those without dynapenia (p < 0.05). In older men, the indicator most sensitive to dynapenia was BMI (71.43%), while the most specific was AC (93.10%). Among older women, the indicator most sensitive to dynapenia was CC (76.92%) and the most specific was AC (77.27%). Conclusion: BMI and CC were found to be better at screening older men and older women for dynapenia, respectively. In addition, AC was the indicator that best identified older people of both sexes without the outcome.
NEOLIBERALISMO, EDUCAÇÃO POSITIVA E INTELIGÊNCIA EMOCIONAL: UMA ANÁLISE A PARTIR DO PENSAMENTO DE MICHEL FOUCAULT
Authors: Benevides Pablo Severiano
Published: June 2024

O presente estudo objetiva estabelecer uma conexão entre a Educação Positiva, o conceito de Inteligência Emocional e leitura foucaultiana acerca do Neoliberalismo. Ao compreender o neoliberalismo como a racionalização da prática governamental, que se configura sob a forma das disciplinas e das biopolíticas, procuramos mostrar o quão próximas se encontram do que, hoje, chamamos de Gerenciamento das Emoções. Sob o amplo conceito de Inteligência Emocional, apresentaremos uma vasta literatura que, por distintas vias metodológicas e analíticas, se propõe a introduzir, no corpo social, um conjunto de intervenções que bem conjuguem a felicidade individual, a otimização das forças produtivas e o bem-estar coletivo. Por fim, indicamos como o campo da Educação, ao buscar lastro nos temas, conceitos e práticas próprios à Psicologia Positiva, se constitui enquanto espaço privilegiado para o Gerenciamento das Emoções que, costurando uma aliança entre os novos humanismos e o neoliberalismo, funda o atualíssimo campo da Educação Positiva.

Key Points

A K-alkali–enriched diet blunted post-uninephrectomy hypertension and facilitated acid clearance by suppressing Na+ reabsorption.

Uninephrectomy-associated proteinuria could be attributed to elevated single-nephron GFR and downregulation of megalin, which reduced fractional protein endocytosis.

Background

Losing or donating a kidney is associated with risks of developing hypertension and albuminuria. Few studies address mechanisms or interventions. We investigate the potential benefits of a K+- alkali–enriched diet and the mechanisms underlying proteinuria.

Methods

Male Sprague Dawley rats were fed either a 2% NaCl+0.95% KCl diet (HNa-LK) or a 0.74% NaCl+3% K+-alkali diet (HK-alk) for 3 weeks before uninephrectomy and then maintained on respective diets for 12 weeks. BP (by tail-cuff), urine, blood, and kidney proteins were analyzed before and after uninephrectomy.

Results

Before uninephrectomy, HK-alk–fed versus HNa-LK–fed rats exhibited similar BPs and plasma [K+], [Na+], but lower proximal (NHE3, sodium bicarbonate cotransporter 1, NaPi2) and higher distal (NCC, ENaC, and pendrin) transporter abundance, a pattern facilitating K+ and HCO3
− secretion. After uninephrectomy, single-nephron GFR increased 50% and Li+ clearance doubled with both diets; in HK-alk versus HNa-LK, the increase in BP was less and ammoniagenesis was lower, abundance of proximal tubule transporters remained lower, ENaC-α fell, and NCCp increased, consistent with K+ conservation. After uninephrectomy, independent of diet, albuminuria increased eight-fold and abundance of endocytic receptors was reduced (megalin by 44%, disabled homolog 2 by 25%–35%) and kidney injury molecule-1 was increased.

Conclusions

The K-alkali–enriched diet blunted post-uninephrectomy hypertension and facilitated acid clearance by suppressing proximal Na+ transporters and increasing K+-alkali secretion. Furthermore, uninephrectomy-associated proteinuria could be attributed, at least in part, to elevated single-nephron GFR coupled with downregulation of megalin, which reduced fractional protein endocytosis and Vmax.
