Authors: Becerra Marina
Published: March 2023

En este artículo se analizan los posicionamientos de las escritoras y maestras Angélica Mendoza -militante comunista- y Herminia Brumana -afín al ideario anarquista-, en relación a los derechos de las mujeres y a las relaciones afectivas en tanto problemas sociales, en la Argentina de los años veinte. Por fuera de los feminismos y en consonancia con las políticas de emancipación femenina de la Rusia soviética, Brumana y Mendoza defendieron el amor libre, la maternidad consciente, la interrupción voluntaria de los embarazos y el goce sexual femenino, además de la autonomía económica y, en el caso de Mendoza, el sufragio femenino. Participaron así, en los debates sobre el lugar de la emancipación femenina en relación con la revolución social. También cuestionaron las representaciones hegemónicas sobre los géneros, imaginando protagonistas mujeres que fueran sujetos de sus textos y contextos.

O conto de Psiquê e Cupido (Apuleio, Metamorfoses, IV, 28-VI, 24), por sua natureza simbólica, apresenta uma série de níveis interpretativos, que ultrapassam a justificativa textual de sua inserção na obra, explicitada, no passo que antecede o relato, pelo uso de auocare (“afastar pela palavra, desviar, distrair”). Nosso propósito aqui é discutir uma dessas camadas significativas da narrativa, a partir da bipartição de Vênus em duas deusas (Venus uulgaria e Venus caeles), tal como apresentada por Apuleio em sua Apologia (12, 1-5), associando-a às figuras da própria Vênus e à de Psiquê, bem como à representação paródica dos deuses do panteão tradicional grego, em especial de Cupido, com ênfase no desfecho da fabula.
Hermias de Alexandria In Platonis Phaedrum Scholia 164-167
Authors: Campos Rogério de
Published: March 2023

Hermias de Alexandria em Platonis Phaedrum Scholia 164,16 – 167,12 apresenta algumas certezas e algumas dúvidas acerca de como interpretar a escala das almas encontradas no Fedro 248c-d. Hermias é o comentador sistemático mais antigo desse diálogo (séc. V. d.C.), mas as duas soluções interpretativas que ele apresenta, apesar de agregar elementos interessantes, não abarcam uma explicação plena nem definitiva do trecho. Hermias apresenta duas interpretações possíveis, cada uma delas de acordo com parâmetros distintos e como, ao cabo desse percurso, põe em dúvida como Platão harmonizava, ou punha em sinfonia, os nove níveis das vidas apresentadas na escala. Apresentaremos também a tradução completa do trecho estudado.
No evidence for a negative association between bovine leukemia virus status and fertility in Kansas beef herds: a cross-sectional study
Authors: Larson Robert L. , Huser Shaun M. , Amrine David E. , White Brad J. , Taxis Tasia M. , Almaraz Juan M. , Weaver Bryan M. , Reif Kathryn E.
Published: March 2023

OBJECTIVE

Determine the association between bovine leukemia virus (BLV) status and fertility in beef cows. BLV-status was defined using 3 different testing strategies (ELISA-, quantitative polymerase chain reaction- [qPCR], and high proviral load [PVL]-status). Fertility was defined as the overall probability of pregnancy as well as the probability of becoming pregnant in the first 21 days of the breeding season.

ANIMALS

Convenience sample of 2,820 cows from 43 beef herds.

PROCEDURES

The association of BLV-status with the probability of becoming pregnant was evaluated with a multivariable logistic regression analysis that used pregnancy status as a binary outcome, herd nested within ranch as a random effect, and BLV-status (ELISA-, qPCR-, and PVL-status as separate models) and potential covariates (eg, age, Body Condition Score [BCS] category, and interactions) as fixed effects.

RESULTS

Raw data revealed that 55% (1,552/2,820) of cows were classified as BLV-positive by ELISA, and 95.3% (41/43) of herds had a least 1 ELISA-positive cow. Classification as BLV ELISA-positive was positively associated with the probability of being pregnant; however, when qPCR or PVL were used to classify BLV-status, there was no association with the probability of being pregnant. None of the methods of classifying BLV-status were associated with the probability of becoming pregnant in the first 21 days of the breeding season.

CLINICAL RELEVANCE

This study did not find evidence that testing beef cows for BLV-status using ELISA, qPCR, or a cut-off of 0.9 PVL and removing test-positive cows will improve cowherd fertility as described by the probability of becoming pregnant during the breeding season or becoming pregnant during the first 21 days of the breeding season.
Bead size has a greater effect on in vitro elution from antimicrobial-impregnated calcium sulfate beads than drug concentration
Authors: Olsen Ronald S. , Sawyere Dominique M. , Davis Jennifer L. , Lanz Otto I. , Werre Stephen R.
Published: March 2023

OBJECTIVE

To compare the elution characteristics of amikacin-impregnated calcium sulfate (CaSO4) beads based on different drug concentrations and bead size configurations.

SAMPLE

Six groups of amikacin-impregnated CaSO4 beads and one negative control group.

PROCEDURES

Amikacin-impregnated CaSO4 beads were formed with either 500 mg (low-concentration) or 1 g (high-concentration) of amikacin per 15 g CaSO4 hemihydrate powder. The number of beads necessary to approximate 150 mg of amikacin for each of the 3 bead sizes (3 mm, 5 mm, and 7 mm) at both low and high concentrations were placed in 6 mL of phosphate-buffered saline. The saline was sampled at 14 time points over 28 days. Amikacin concentrations were determined using liquid chromatography-mass spectrometry.

RESULTS

Smaller beads reached higher mean peak concentrations than larger beads (P < .0006). Peak concentrations for the low- and high-concentration groups were 20.5 mg/mL and 27.4 mg/mL, 13.1 mg/mL and 14.0 mg/mL, and 8.85 mg/mL and 6.75 mg/mL for the 3 mm, 5 mm, and 7 mm beads, respectively. Bead size also affected the length of therapeutic duration, lasting 6 days for the 3 mm and 5 mm beads and 9 days for the 7 mm beads. However, this was only statistically evident among the high-concentration beads (P < .044). Antimicrobial concentration within the same bead sizes did not affect elution.

CLINICAL RELEVANCE

Amikacin-impregnated CaSO4 beads achieved extreme supratherapeutic eluent concentrations. While additional studies are needed, bead size significantly affected elution with smaller beads reaching higher peak concentrations and 7 mm, high-concentration beads demonstrating a longer therapeutic duration than smaller beads.

Published: March 2023

Background: Happiness at work is an important factor in employee satisfaction, productivity and retention. This study aimed to investigate the relationship between perceived manager’s emotional intelligence and happiness at work, and whether job satisfaction and affective organizational commitment mediate this relationship.

Method: A questionnaire was distributed online to a random sample of 350 schoolteachers in Saudi public schools teaching different majors.

Results: Structural equation modelling results showed that satisfaction and affective organizational commitment fully mediated the relationship between perceived manager’s emotional intelligence and happiness at work.

Conclusion: Our results support the hypothesis that perceived manager’s emotional intelligence influences employee happiness through its influence on increasing or decreasing job satisfaction and affective organizational commitment. These findings therefore provide insight into employee’s wellbeing and potentially how to promote it.

Conclusion: Organizations should consider the impact of employee CSR perceptions on creative performance, indirectly through extrinsic and intrinsic job satisfaction and organizational citizenship behavior to achieve higher levels of creative performance within their organizations.
LA LIMITE SANS LIMITES QUELQUES RREMARQUES SUE LE PRINCIPE PHENOMENOLOGIQUE DE LA GEGEBENHEIT A L’EPREUVE DU NEOKANTISME
Authors: Mariani Emanuele
Published: March 2023

What, if any, are the limits of the Husserlian concept of Gegebenheit? Is there a limit beyond which nothing can be seen by the phenomenologist? In asking these questions, we allude to a distinction typical of Kantian criticism: “Grenze” or “Schranke”, limit or boundary? These same questions are reformulated in a famous review of Ideen I by Paul Natorp, a Marburg neo-Kantian who directly attacks the unlimited scope Husserl gives to the phenomenological principle of intuition. From a phenomenological point of view, however, the Achilles’ heel of the critical method lies in the impossibility of accessing by intuition, beyond phenomena, the thing-in-itself. A major consequence is that the phenomenological dissolution of the “Grenze” prescribes a limitless opening to the horizon of phenomena. But if we can speak of a limitless openness, it is because in a certain way everything gives itself to be seen. What kind of vision is this? And what kind of Gegebenheit is at work here? The Husserlian answer lies in the recovery of a concept, the “idea in the Kantian sense”, without its counterpart, the “limit”, whereas for Kant as well as for Natorp it is precisely the concept of “limit” that characterizes the gnoseological status of the “idea”.

This article is based on a case study of a Romanian company named SC Mecanica Ceahlău SA. The main aim of the paper is to present the development perspectives of the Romanian economy and the agricultural machinery industry. Determining the external and internal context of the organization's operations required determining its relationship to the organization's environment, including the company's strengths, weaknesses, opportunities, and threats in SWOT analysis and, positioning the organization in the competitive environment specific to the field in which it operates. Particular attention was paid to examining the development context of the Romanian economy and the strategic directions developed in the production and sale of agricultural machinery and equipment. In an agriculture undergoing technical and social restructuring as Romanian agriculture is currently presented, the increase of the endowment with technical equipment depends on the capacity of the existing producer organizations on the market to cover the demand for them, both in terms of quantity and from a qualitative point of view.
SUSTAINABLE MANAGEMENT IN THE GIG ECONOMY: TRADITIONAL VS. GIG BUSINESS MODEL IN THE DELIVERY SECTOR
Authors:   Bucharest University of Economic Studies, Romania, IANCU Adriana Lavinia
Published: March 2023

In a global energy and natural gas crisis and high inflation rate caused by geopolitical tensions and war, the question of achieving sustainability arises. In the stringent needs of today’s lives and future ones, governments and privately-held company managers have to prioritise, choosing between the transitions towards the old and the new, between opening coal mines and implementing renewable energy systems, between people and profit, between profit and planet, between planet and people. Thus, the current article explores sustainable management principles by looking at the delivery sector, one of the most affected by the increasing fuel price and technological advancement, in which traditional and GIG economy models coexist and challenge the people, planet and profit status quo. Navigating through the main theories in the field of sustainability from governmental, non-governmental, and environmental perspectives, this article clarifies the GIG economy principles, thriving to find a compiling business model for the delivery sector. The theoretical analysis has served to design a quantitative questionnaire dedicated to GIG workers, which revealed that sustainable management in the GIG economy, applied to the delivery sector, has a long way to go towards respecting the independence criteria imposed by legislation and balancing the fair payment and incentivising eco-practices.

The current economy's flow is given by the dynamism of the multinational companies which are acting globally, increasing the openness of the countries regarding trade through foreign direct investment. With the international financial institutions leading backing them up, privatization, greenfield investments and mergers & acquisitions were strongly promoted as a tool to reduce the budgetary burden caused by state enterprise, bad private management, or other private and public sector inefficiencies, so that FDI inflows can contribute to the increase rate of GDP and also can have a positive impact on the exports flow. In order to see how well this purpose has been achieved by some countries, some economic indicators need to be addressed. That is why the purpose of this study is to presents the economic evolution of those countries which had arrangements with the IMF, from different regions of Europe, Latin America and Asia during the past 30 year, from 1990- 2020, analyzing their Gross Domestic Product, Foreign Direct Investments, and Export with the Compound Annual Growth Rate metric. All the statistical data is taken from the UNCTAD, and the numbers of IMF agreements or arrangements are taken from the IMF website.

Published: March 2023

The aim of this research is to contribute to the literature in the field, filling the gap concerning how logistics impacts the relationship between pollution and economic complexity worldwide. Investigating the weights of the multiple dimensions of logistic performance appears very relevant and strengthens the literature in the field in terms of studies carried out in abnormal times that impact society and the economy at their core. From a methodological standpoint, this study uses a structural equations approach, revealing a complex mediating chain linking pollution with logistics performances. Our results show that logistics is a net contributor to pollution and further investment in supply chain green innovation is needed to achieve the objectives of green logistics.

Published: March 2023

In this paper, we apply Data Envelopment Analysis with constant and variable returns to scale to study the technical efficiency of 42 countries for 2019 starting from 12 inputs and 3 outputs. The inputs represent the features of entrepreneurial framework conditions, which can be managed by governments to enhance or hinder new business creation, i.e., the outputs of total entrepreneurial activity (TEA) and the ratio of male-female TEA together with (iii) entrepreneurial intentions. The two models show that for the VRS approach, the number of efficient entities is larger than in the case of the CRS approach. The results show that the mean values of the CRS and VRS models reveal that the countries have entrepreneurial activities on the efficient frontier if the use of the input may be reduced by 7.73%, and by 3.17% under CRS and VRS models, respectively, without any decrease in the outputs.
Development of an Antimicrobial Topical Skin Cream with Using Wood Apple (Limonia acidissima L.) Pulp Against Staphylococcus aureus, Pseudomonas aeruginosa and Candida albicans
Authors: Fasha Fathima , Yapa Neelamanie
Published: March 2023

Skin inhabiting microbes mostly non-pathogenic and commensals on the skin. Among them Staphylococcus aureus, Pseudomonas aeruginosa, and Candida albicans often responsible for symptomatic skin infections. Cellulites, impetigo, ecthyma, red lesions and candidiasis are some of the common microbial skin diseases caused by skin pathogens. Wood apple (Limonia acidissima L.) is an underutilized fruit in Sri Lanka and, all parts of this plant have medicinal value. Considering the high therapeutic value, the aqueous extract of wood apple pulp was used. Antibacterial activity against Staphylococcus aureus, Pseudomonas aeruginosa and antifungal activity against Candida albicans was evaluated by using the standard well diffusion method. Above tested bacterial and fungal species were suspended in 3 mL of sterile distilled water separately and 108 CFU/mL population count was prepared. Aliquots of 100 µL of each suspension were inoculated and uniformly spread on Muller Hinton agar plates separately in triplicates. Wells were filled aseptically placing 50 µL of wood apple extracts, antimicrobial compounds specifically as the positive control for bacteria and fungi and sterile distilled water as the negative control. The plates were incubated at 37 °C for 24 - 48 hours and the diameter of the growth inhibition zones around the wells were measured. Furthermore, minimum inhibition concentrations of each extract were also evaluated. Comparisons were performed using one-way ANOVA followed by Tukey’s Pairwise Comparisons. The antimicrobial topical skin cream was prepared using 0.5 g mL-1 of wood apple pulp with sterile distilled water, mixed with the formulated standard ingredients. The results revealed that the aqueous extracts of wood apple pulp concentrations range from 0.15 g mL-1 to 1g mL-1 showed the antimicrobial potential of above skin pathogens variably ranged inhibition zone diameter 16 mm to 34 mm. The antimicrobial effect of the formulated cream against these pathogens was repeatedly tested. Further testing procedures needed to be followed before recommending wood apple topical antimicrobial skin cream as a marketable product.
Effect of Red Pepper (Capsicum annuum L.) Oil Addition to Growing Quail Diets on the Performance, Slaughtering and Some Serum Characteristics
Authors: Gül İlker , Cufadar Yusuf
Published: March 2023

The aim of this study is to determine the effects of adding different levels of red pepper oil to quail diets on performance, slaughtering characteristics, and some serum parameters. For this purpose, a total of 300-day-old and mixed-sex quail chicks were randomly assigned to 5 treatment groups with 6 replications of 12 chicks each. Experimental animals were fed for 35 days with 5 different diets prepared by adding 0, 300, 600, 900 or 1200 mg/kg red pepper oil. During the experiment, quails were given ad-libitum feed and water. According to the results of the experiment, the effect of adding red pepper oil to the diet on the performance, carcass traits and visceral weights of the quails was statistically insignificant. Triglyceride and TAS concentrations of serum were significantly affected by the addition of red pepper oil to the diet. The highest triglyceride and TAS levels in the group with 300 mg/kg red pepper oil added; however, the lowest triglyceride and TAS levels were obtained in the groups supplemented with 600 mg/kg and 1200 mg/kg red pepper oil, respectively. According to this study findings, it can be said that the addition of red pepper oil to the diet in growing quails has a positive effect on serum triglyceride and TAS values when used between 300 mg/kg and 600 mg/kg in the diet, without adverse effects on performance and carcass characteristics.
Some Characteristics of Breakfast Spreadable Cornelian Cherry (Cornus mas L.) Nectar Produced Using Potentially Probiotic Starter Culture
Authors: Alp Duygu , Mısır Samet
Published: March 2023

In this study, it was aimed to make a breakfast spreadable Cornelian cherry nectar similar to marmalade. Lactiplantibacillus plantarum DA100 strain, which has potential probiotic properties, was added to this nectar.  It was investigated whether this strain has an effect on various sensory properties of nectar. In the study, sensory and various chemical properties of nectar produced without probiotic microorganism were determined. Since the breakfast spreadable Cornelian cherry nectar produced in our study was not exposed to high temperatures for a long time, a very low HMF of 4.290 mg/kg was determined. Vitamin C was determined as 716.800 mg/L and total phenolic content was determined as 3156.64 mg GAE/100g. In the probiotic group, the microorganism viability, which was 1.5×1010 Log CFU/mL initially, was determined below approximately 1.5×106 Log CFU/mL at the end of 5 days. In addition, coliform bacteria and E. coli were not detected in any group during this period. Contrary to the texture score, the difference between the sensory evaluation results of the probiotic-added and the control group of breakfast spreadable Cornelian cherry nectar was significant in taste, bitterness, odor and sourness. An alternative to jams and marmalades, rich in vitamin C and phenolic content, limited HMF production, and a functional product with low sugar content were tried to be obtained, and when the results obtained are evaluated, the product is thought to be promising.

Este trabajo aborda y problematiza nuestras narrativas docentes sobre las prácticas de enseñanza llevadas a cabo en la emergencia sanitaria desatada por el Covid-19 en el año 2020 y mantenida durante el 2021. Asimismo, anuncia brevemente algunas problemáticas que advertimos sobre la vuelta a las aulas en el ciclo lectivo 2022. Como docentes universitarias, la forma de enseñanza en la virtualidad nos despertó inquietudes acerca de las herramientas digitales y su uso para lograr la finalidad esencial de la educación: el vínculo docente-estudiante-conocimiento. La estrategia metodológica se basa en la revisión de narrativas docentes de nuestras prácticas en los últimos dos años en la Universidad Provincial de Córdoba, Argentina. En base a esto, problematizamos sobre los vínculos en relación a los siguientes ejes: el espacio-tiempo, el lugar del cuerpo, y nuestro rol como profesoras.

Reflexionamos sobre cómo las fronteras espaciales y temporales del aula se volvieron difusas, entremezcladas y solapadas con otras de ámbitos familiares y laborales. El cuerpo fue el gran ausente y los encuentros aúlicos se tensionaron. Aún así, durante el 2020 y el 2021 vivimos experiencias de enseñanza que suscitaron vínculos pedagógicos, enfatizando la necesidad de presencia de los educadores.
La escuela que no es
Authors: Pla Sebastián
Published: March 2023

Este trabajo ofrece una discusión sobre las actuales circunstancias que envuelven la categoría ‘escuela’ y las repercusiones que conlleva –para este tiempo/espacio educativo– la crisis derivada de la pandemia de Coronavirus y la consiguiente postpandemia. El contexto en el que se enmarca el análisis es el de la escuela latinoamericana y la posición del autor es, a la vez, de observador y observado, es decir, ubicándose desde dentro del fenómeno social estudiado y vivido. Las preguntas que rondan estas discusiones son ¿qué tipo de escuela es la “escuela pandémica? y, a su vez, ¿qué de esta “escuela pandémica” definitivamente nos aleja de lo que hemos entendido por escuela hasta ahora? El texto cierra con un conjunto de reflexiones que permitan afrontar la crisis postpandemia abordando los peligros que conlleva la permanencia de los elementos más institucionales de la escuela y el debilitamiento de sus simbolismos emancipatorios.

This study examined the association between resilience and coping strategies on post-traumatic stress symptoms in Muslim university students. The study used a cross-sectional design and gathered data from 1157 participants using four questionnaires. The results showed that higher levels of resilience were related to higher coping strategies and lessened post-traumatic stress symptoms. In comparison, higher levels of coping strategies were correlated with lower levels of post-traumatic stress symptoms. In addition, the regression analysis revealed that resilience and coping strategies were significant predictors of post-traumatic stress symptoms, with resilience predicting lower levels of post-traumatic stress symptoms and coping strategies predicting higher levels. These findings suggest that interventions focusing on improving resilience and coping strategies may help reduce post-traumatic stress symptoms among Muslim university students. However, further research is needed to confirm these findings and examine this association's underlying mechanisms.

Согласно концепции, рефлектор представляет собой тонкую композитную оболочку и имеет регулировочные узлы, для коррекции формы. Задачами цифрового двойника являются: - моделирование отклонения формы на этапах создания и эксплуатации; - расчет оптимальной коррекции для минимизации отклонения. Для решения задач представлены численные тепловая модель и модель деформирования. Первая предназначена для расчета температурного поля рефлектора от действия теплового потока на орбите. Вторая - для расчета отклонения и коррекции формы с учетом расчетного температурного поля.

According to the concept, the reflector is a thin composite shell which has several adjustment nodes for shape correction. The tasks of the digital twin are: - modeling of the shape deviation for assembly and operation stages; - calculation of the optimal correction to minimize the shape deviation. To solve these problems, the thermal and the deformation numerical models are presented. The thermal model calculates the temperature field of the reflector considering the heat flux on orbit. The deformation model calculates the shape deviation and correction, taking into account the affecting temperature field.

End-stage renal failure is a debilitating condition with a high level of mortality. One of the most effective approaches for ameliorating these conditions is hemodialysis. It saves hundreds of thousands of patients every year from premature death. Increasing dialysis efficiency is a core proponent of hemodialysis. Accordingly, an increase in dialysis efficiency means that hemodialysis is improved. A number of approaches have been taunted as effective in improving dialysis efficiency. One of these approaches is increasing the dialysate flow rate. The research, however, on the effect of dialysis flow rate on dialysis efficiency is not conclusive because some studies suggest that an increase in dialysis flow rate increases dialysis efficiency, while other researches point out that an increase in Qd has minimal to no impact on dialysis efficiency.

Background: Administration of medications is primarily the nurse’s responsibility. This study aimed to assess intensive care nurses’ practice of safe medication administration in governmental hospitals in the Gaza Strip. Methods: This study utilized descriptive, cross-sectional, analytical design. The sample of the study consisted of 116 ICU nurses from five governmental hospitals (Al Shifa Hospital, Indonesy Hospital, Shohada Al Aqsa hospital, European Gaza Hospital, and Nasser Hospital). For data collection, the researcher used Patient Safety Assessment in Medication Administration Questionnaire and Observation Checklist. A pilot study was conducted on 20 nurses, and reliability of the Patient Safety Assessment in the Medication Administration Questionnaire was 0.908. Results: The results showed that 66.4% of study participants were male nurses and 33.6% were female nurses, mean age was 28.97 years, 85.4% have bachelor degree, mean experience was 4.18 years, mean income was 1431.64 New Shekel, and 67.2% are working mixed shifts (morning, evening, and night). The practice of safety medication administration indicated that the highest score was in right route (93.8%), the right time (91.8%), right patient (90.7%), right way (89.5%), right recording of administered medication (88.9%), right answer (86.7%), right guidance (86.5%), right dose (86%), right medication (85.3%), and the overall score was 88.6%.

Medicinal oils, including fixed and essential oils, are one of the most ancient forms of medicines. Animals and plants are the major source of fixed oils which have been reported to treat various ailments, such as urinary, nervous, respiratory, cardiovascular, musculoskeletal disorders, bacterial, fungal and protozoal infections etc. Medicinal oils, especially of animal origin are; however, ignored and rarely investigated in contemporary modern medical research. This study was aimed to investigate the various pharmacological activities of fixed oil of Gallus gallus domesticus (Egg oil, Fo.Gg). Fo.Gg was investigated for its wound healing potential by using excisional wound model, anti-arthritic activity by following turpentine oil-induced acute arthritis model, antipyretic activity by yeast-induced pyrexia, anxiolytic activity by adopting hole board, light/dark exploration and elevated plus maze models, antidepressant activity by forced swim test and tail suspension model and antiamnesic activity by Y-maze model. Fo.Gg showed significant healing potential as evident from increase in percent wound contraction and decrease in period of epithelialization and also the significant decrease in paw and ankle joint diameter in anti-arthritic activity. It showed dose-dependent (i.e. 10, 30 and 50%) decrease in rectal temperature when compared to the control group, also showed significant anxiolytic, antidepressant and anti-amnesic activities. These pharmacological activities may be attributed to the antioxidant as well as radical scavenging potential of oil components especially polyphenols, oleic acid and linoleic acid. Thus, the results of the study conclude that egg oil possesses wound healing, anti-arthritic, antipyretic, anxiolytic, antidepressant and anti-amnesic potential. The study provides scientific ground for the folkloric use of the oil in traditional system of medicine; however, further studies are required to explore the possible mechanism(s) of action.

Hypoxia-inducible factor-1alpha (HIF-1alpha) constitutes the principal mediator of cellular adaptation to hypoxia in humans. Hydroxylation of proline residues on HIF-1alpha is recognized by the E3 ligase von Hippel-Lindau (VHL), leading to ubiquitin-dependent proteasomal degradation of HIF-1alpha. In this study, we performed a structure-guided and bioactivity-driven design of new VHL inhibitors with improved cellular activity at blocking HIF-1alpha degradation. With the prototypical ligand VH298 as starting point, our iterative and combinatorial optimization strategy focused on introducing chemical variability into the phenylene unit of the VHL ligand structure and encompassed further points of diversity. The exploitation of tailored phenylene fragments combined with the stereoselective installation of the (S)-configured methyl group at the benzylic position provided VHL ligands with superior binding affinity compared to VH298. Three high-resolution structures of VHL in complex with three new ligands were determined and bioactive conformations of these ligands were explored. The most potent inhibitor (compound 30) exhibited dissociation constants (Kd) lower than 40 nM, independently determined by fluorescence polarization (FP) and surface plasmon resonance (SPR). The improved binding affinity to VHL was accompanied by enhanced cellular potency of 30, considerably exceeding the stabilization of HIF-1alpha by established VHL inhibitors. Our work is anticipated to inspire future efforts towards HIF-1alpha stabilizers and our optimized ligands to serve as an excellent starting point for proteolysis-targeting chimeras (PROTACs) hijacking VHL.
