Significance Statement
Podocyte detachment is a major contributor to kidney disease progression, yet the mechanisms controlling podocyte adhesion are not well understood. We identified novel roles for Nck1 and Nck2 cytoskeletal adaptor proteins in cell adhesion through regulation of actin bundling at focal adhesions via α actinin-4. In vivo, loss of Nck1 and/or Nck2 increases basement membrane matrix deposition and renders podocytes more susceptible to damage after injury and with aging. More severe defects are observed with Nck2 deficiency, consistent with identification of distinct effector proteins. The results suggest an essential role for Nck adaptors as molecular hubs integrating multiple actin-based signals to control podocyte adhesion dynamics.

Background
Maintenance of the kidney filtration barrier requires coordinated interactions between podocytes and the underlying glomerular basement membrane (GBM). GBM ligands bind podocyte integrins, which triggers actin-based signaling events critical for adhesion. Nck1/2 adaptors have emerged as essential regulators of podocyte cytoskeletal dynamics. However, the precise signaling mechanisms mediated by Nck1/2 adaptors in podocytes remain to be fully elucidated.

Methods
We generated podocytes deficient in Nck1 and Nck2 and used transcriptomic approaches to profile expression differences. Proteomic techniques identified specific binding partners for Nck1 and Nck2 in podocytes. We used cultured podocytes and mice deficient in Nck1 and/or Nck2, along with podocyte injury models, to comprehensively verify our findings.

Results
Compound loss of Nck1/2 altered expression of genes involved in actin binding, cell adhesion, and extracellular matrix composition. Accordingly, Nck1/2-deficient podocytes showed defects in actin organization and cell adhesion in vitro, with podocyte detachment and altered GBM morphology present in vivo. We identified distinct interactomes for Nck1 and Nck2 and uncovered a mechanism by which Nck1 and Nck2 cooperate to regulate actin bundling at focal adhesions via α actinin-4. Furthermore, loss of Nck1 or Nck2 resulted in increased matrix deposition in vivo, with more prominent defects in Nck2-deficient mice, consistent with enhanced susceptibility to podocyte injury.

Conclusion
These findings reveal distinct, yet complementary, roles for Nck proteins in regulating podocyte adhesion, controlling GBM composition, and sustaining filtration barrier integrity.

This research aims to determine the factors that affect teachers’ trust in male and female leaders. The study employed a qualitative research design. The data were collected with interview technique. In this regard, 20 teachers were interviewed. The participants were determined with purposeful sampling method. The data were analyzed with inductive analysis method. Results revealed that the participant teachers trust different behaviors or characteristics of their male or female leaders. In general, teachers trust in their female leaders’ more because of their objective, idealistic, dedicated behaviors, and also their motherly, sensitive and compassionate personality. On the other hand, teachers trust in their male leaders as they are fair, trustworthy, frank, competence, more rational and strong communicators. While male leaders are believed to take initiative and implement the laws and regulations more strictly, female administrators are more interested in the administration profession, behave meticulously and work devotedly. It is recommended that school administrators should create a climate of objectivity and trust in school.
On the Limitations of Spectral Source Parameter Estimation for Minor and Microearthquakes
Authors: Parolai Stefano , Oth Adrien 
Published: July 2022

ABSTRACTReliable estimation of earthquake source parameters is fundamental to improve our understanding of earthquake source physics and for ground-motion modeling in seismic hazard assessment. Nowadays, methods traditionally used for investigating the source parameters of earthquakes with Mw≥3, such as spectral fitting or spectral ratio approaches, are also extensively applied to smaller magnitude events because of the increase in the number of stations and the more common borehole installations. However, when working with recordings of such minor and microearthquakes, significant limitations of the usable frequency range spanned by the spectra arise. At the lower end, signal-to-noise ratio constraints limit the usage of low frequencies, whereas at the upper end, the sampling rates of typical seismological networks as well as high-frequency attenuation can be limiting factors. In addition, earthquake source parameters determined from ground-motion spectra are known to exhibit potentially serious trade-offs, in particular the corner frequency and high-frequency attenuation. In this study, we go beyond the typical discussion of these trade-offs using simplistic spectral models by investigating the impact of the background wave propagation model on the source parameter trade-offs as well as its effect on the feasibility of obtaining useful source parameters by means of spectral fitting for minor and microevents. The analysis takes advantage of ad hoc simulated synthetic seismograms with well-defined underlying background propagation models and considers increasing complications in these models (intrinsic and scattering attenuation). The results show that with given realistic background models and usable frequency bands, the source parameter estimation for minor and microevents can be significantly biased, and not surprisingly, this bias is mainly affecting the estimation of the corner frequency. We highlight the inherent limitations of joint spectral fitting approaches for the determination of source parameters from minor and microearthquakes, which should always be viewed with great caution when physically interpreted.

Background: The initial stage of plants and sunlight as the energy source are very critical for plants. A boost of biochemical reactions given by concentrating solar energy at the initial stage of plants may continue accelerated growth and yield. Rice is a high-demand crop. Therefore, in this research study, the germination of rice seeds was studied under different radiation levels using a spherical solar concentrator (SSC). Methods: The germination percentage of rice seeds was observed under different radiation levels. Experimental setup 1 consisted of 60 cm below the SSC (SSC 60 cm) and open environment (OE) whereas Experimental setup 2 consisted of 45 cm below the SSC (SSC 45 cm) and OE. Result: SSC (60 cm) and SSC (45 cm) manifested 1.2 and 1.5 times higher solar energy than the OE, respectively. In experimental setup 1, it was observed germination percentages of 65.2 and 58.8 in SSC (60 cm) and OE, respectively whereas, in the experimental setup 2, 86.9 and 77.5 in SSC (45 cm) and OE, respectively. It can be assumed that plants grown under SSC during the nursery stage, reach the fullest potential at maturity as a result of increased flux density and lower soil temperature under the SSC.

Визначення якості відтворення гравійованих штрихів та виявлення зaкономiрностей формувaння фaрбового шaру тa його зaлежностей вiд параметрів друкарських форм, виготовлених за технологією DLE, є aктуaльним нaуково-технiчним зaвдaнням, вирішення якого забезпечить надання певних наукових рекомендацій щодо технологічного процесу виготовлення DLE форм. Тому метою дослідження було встановити взаємозв'язок якості відтворення запроектованого профілю гравійованих штрихів форм інтагліодруку, отриманих прямим лазерним гравіюванням з подальшим нанесенням захисного покриття нітриду хрому напиленням, та графічної та градаційної точності відбитків інтагліодруку, виготовлених із застосуванням цих форм. Для досягнення цієї мети була виготовлена модельна форма із вигравійованими друкарськими елементами заданих геометричних параметрів, віддруковані зразки та проведено дослідження впливу різної геометрії та співвідношення сторін поперечних профілів на якість відтворення штрихів на відбитках.
Вивчення мікрошліфів, здіснене за допомогою оптичного металографічного мікроскопу Neophot-32 показало, що всі гравійовані штрихи зразка мають відхилення від заданого геометричного профілю, зазвичай є несиметричними та із різною мікрогеометрією поверхні вигравійованих елементів.
Дослідження надрукованих штрихів, здійснені за допомогою монокулярного цифрового мiкроскопa МОЦ–45 Мiкротех при збiльшеннi 45× iз системою вiзуaлiзaцiї Micam та профілографічного аналізу iз зaстосувaнням профiлометрa моделi 296, показали, що існує залежність показників якості формування фарбового шару від коефіцієнта спiввiдношення глибини до ширини гравійованих штрихів. Зокрема була досліджена залежність коефіцієнта втрати товщини фарбового шару, коефіцієнта розтікання фарби, показника шприцювання при фарбоперенесенні у інтагліо друці. У результаті проведених досліджень наведені рекомендації щодо підбору геометричних параметрів гравійованих елементів форми інтагліо друку.
