Stress in learning is a feeling faced by a person when there are pressures on him. The pressures in question are related to learning and school activities, such as the grace period of the task, on the eve of exams and thesis. The purpose of the study was to find out if there was any effect of providing progressive muscle relaxation techniques on students' stress levels during the covid-19 pandemic at the Muslim University of Indonesia. This type of research is a type of quantitative research. The research design used is a pre-experimental method with the One Group Pretest-Posttest Design approach. The determination of samples was done by purposive sampling technique with a large sample of 52 respondents. The comparison test is conducted using a paired t-test sample. The results of this study showed that before being given progressive muscle relaxation techniques to 52 students, stress was in the mild category of 35 students, while as many as 17 students while after being given progressive muscle relaxation techniques to 52 students obtained stress levels all students were in the normal category as many as 52 students. It can be concluded that there is an influence between progressive muscle relaxation techniques on stress levels with a significance value of 0.000 < 0.05, which is then expected to be more research on stress in students during the covid-19 pandemic so that more references, further research needs to be done with other methods and more samples in order to get more accurate results, because covid-19 causes the process of providing proresive muscle relaxation techniques that are It should be more effective face-to-face but because it is still a pandemic so researchers have to provide action online and only a small percentage of respondents can come face to face for the provision of progressive muscle relaxation techniques.

Abstrak Amfiteater Ciletuh merupakan bentang alam unik berbentuk tapal kuda yang terbuka ke arah barat dengan dimensi panjang sekitar 15km dan lebar 9km. Bentang alam ini berada di kawasan Geopark Ciletuh-Palabuhanratu, kabupaten Sukabumi. Teori pembentukan amfiteater ini menyebutkan bentukan ini terbentuk akibat keruntuhan yang dipicu tumbukan meteorit dan ada pula yang menyebutkan akibat gravity collapse. Metode analisis kekasaran citra digunakan untuk melihat garis patah di dinding amfiteater. Analisis inverse paleostress digunakan untuk mengetahui fase tektonik di daerah penelitian. Bentuk amfiteater tidak sirkular sempurna, namun mengikuti pola-pola kelurusan yang searah dengan sesar yang ada. Nilai indeks kekasaran pada DEM menunjukan nilai tinggi sepanjang amfiteater yang diartikan sebagai garis patah dari keruntuhan. Penampang lereng amfiteater menunjukan adanya perbedaan bentuk lereng yang mengindikasikan pengaruh struktur geologi yang berbeda di sepanjang lereng. Hasil analisis inverse paleostress menunjukan setidaknya ada dua fase tektonik yang mempengaruhi pembentukan amfiteater diantaranya fase “rezim tegasan strike-slip” dan fase “rezim tegasan ekstensional”.

Introduction:Bacillus species are known for their ability to produce nanoparticles with various potential applications.Methods: In this study, we present a facile approach for the green synthesis of selenium nanoparticles (Se NPs) using the biogenic selenate-reducing bacterium Bacillus paramycoides 24522. We optimized the growth conditions and sodium selenite reduction efficiency (SSRE) of B. paramycoides 24522 using a response surface approach.Results: Se NPs were synthesized by reducing selenite ions with B. paramycoides 24522 at 37 °C, pH 6, and 140 r/min, resulting in stable red-colored Se NPs and maximal SSRE (99.12%). The synthesized Se NPs demonstrated lethality against Staphylococcus aureus and Escherichia coli with MICs of 400 and 600 μg/mL, and MBCs of 600 and 800 μg/mL, respectively, indicating the potential of Se NPs as antibacterial agents. Furthermore, the Se NPs showed promising antioxidant capabilities through scavenging DPPH radicals and reducing power.Discussion: This study highlights the environmentally friendly production of Se NPs using B. paramycoides 24522 and their possible applications in addressing selenium pollution, as well as in the fields of environment and biotechnology.

Published: August 2023

This paper explores human observer preferences for various sky-like interior lighting scenarios realized by a combination of a blue-enriched indirect uplight component with a correlated color temperature (CCT) of 6,500 K up to 30,000 K and a 4,000 K or 5,500 K direct downlight component. Variations in the natural sky were mimicked by the indirect uplight component reflected from the ceiling of the experimental room. The settings for the direct lighting component, on the other hand, were selected based on the reported outcomes of previous preference studies in the field of interior lighting. The resulting lighting conditions were evaluated by a total of 29 observers, from which subjective ratings of brightness, sky-likeness, satisfaction, pleasantness, and general appeal were collected in an office workplace environment. In this experimental setting, the most preferred lighting conditions exhibited a direct-to-indirect lighting ratio of 50:50 with a CCT of 4,000 K in the direct component and 6,500, 7,500, and 9,000 K in the indirect component. For all examined combinations, none was rated as truly sky-like. Nonetheless, the study results showed that only the combination of a warmer CCT in the direct component and a cooler, blue-enriched CCT in the indirect lighting component leads to a maximum in the subjects’ preference ratings. In summary, the subjects preferred light settings with a white appearance on the work surface without any intense or noticeable blue cast or tint.

The (pro)renin receptor ((P)RR; also known as ATP6AP2) is a multifunctional receptor. The (P)RR activates the tissue renin-angiotensin system (RAS) and is also involved in regulating integral intracellular pathways such as V-ATPase and Wnt/β-catenin signalling. Given this, the (P)RR may be associated with essential pathways in placentation, however its role within the context of pregnancy remains poorly characterised. The first trimester/extravillous trophoblast cell line, HTR-8/SVneo, underwent an siRNA knockdown where they were incubated for 24 h with a negative control siRNA or siRNA targeting ATP6AP2 mRNA. xCELLigence real-time cell analysis was performed to assess the effect of ATP6AP2 mRNA knockdown on HTR-8/SVneo cell proliferation, migration, and invasion. In subsequent experiments, GFP-encoding lentiviral packaged gene-constructs were used to knockdown (P)RR expression in the trophectoderm of C57/BL6/CBA-F1 mouse blastocysts. Blastocysts were incubated for 6 h with vehicle (no-virus), control virus (non-targeting shRNA and GFP), or (P)RR-knockdown virus ((P)RR shRNA and GFP) before transfer into recipient pseudo-pregnant Swiss CD1 female mice. Fetal and placental tissues were collected and assessed at embryonic age (EA) 10 and 18. (P)RR levels were measured in the labyrinth zone of day 18 placentae and stereological Merz grid analysis was performed to determine the volumetric distribution of trophoblasts, fetal capillaries, and the maternal blood space. We showed that a reduction of ATP6AP2 expression in HTR-8/SVneo cells in vitro, impaired trophoblast proliferation, migration, and invasion. In vivo, decreasing placental labyrinth (P)RR expression adversely effected placental physiology, decreasing placental trophoblast number and total surface area available for exchange, while also increasing maternal blood space. Additionally, decreased (P)RR affected placental efficacy evident by the reduced fetal-placental weight ratio. Our study shows that the (P)RR is necessary for appropriate placental development and function.

BackgroundAcute myocardial infarction (AMI) is the major cause of cardiovascular mortality worldwide. Most ischemic episodes are triggered by an increase in heart rate, which induces an imbalance between myocardial oxygen delivery and consumption. Developing drugs that selectively reduce heart rate by inhibiting ion channels involved in heart rate control could provide more clinical benefits. The Cav1.3-mediated L-type Ca2+ current (ICav1.3) play important roles in the generation of heart rate. Therefore, they can constitute relevant targets for selective control of heart rate and cardioprotection during AMI.ObjectiveWe aimed to investigate the relationship between heart rate and infarct size using mouse strains knockout for Cav1.3 (Cav1.3−/−) L-type calcium channel and of the cardiac G protein gated potassium channel (Girk4−/−) in association with the funny (f)-channel inhibitor ivabradine.MethodsWild-type (WT), Cav1.3+/−, Cav1.3−/− and Girk4−/− mice were used as models of respectively normal heart rate, moderate heart rate reduction, bradycardia, and mild tachycardia, respectively. Mice underwent a surgical protocol of myocardial IR (40 min ischemia and 60 min reperfusion). Heart rate was recorded by one-lead surface ECG recording, and infarct size measured by triphenyl tetrazolium chloride staining. In addition, Cav1.3−/− and WT hearts perfused on a Langendorff system were subjected to the same ischemia-reperfusion protocol ex vivo, without or with atrial pacing, and the coronary flow was recorded.ResultsCav1.3−/− mice presented reduced infarct size (−29%), while Girk4−/− displayed increased infarct size (+30%) compared to WT mice. Consistently, heart rate reduction in Cav1.3+/− or by the f-channel blocker ivabradine was associated with significant decrease in infarct size (−27% and −32%, respectively) in comparison to WT mice.ConclusionOur results show that decreasing heart rate allows to protect the myocardium against IR injury in vivo and reveal a close relationship between basal heart rate and IR injury. In addition, this study suggests that targeting Cav1.3 channels could constitute a relevant target for reducing infarct size, since maximal heart rate dependent cardioprotective effect is already observed in Cav1.3+/− mice.

Published: August 2023

Pumpkin (Cucurbita moschata Duch.) productivity is severely hindered by powdery mildew (PM) worldwide. The causative agent of pumpkin PM is Podosphaera xanthii, a biotrophic fungus. Pathogenesis-related protein 1 (PR1) homolog was previously identified from transcriptomic analysis of a PM-resistant pumpkin. Here, we investigated the effects of CmPR1 gene from pumpkin for resistance to PM. Subcellular localization assay revealed that CmPR1 is a cytoplasmic protein in plants. The expression of CmPR1 gene was strongly induced by P. xanthii inoculation at 48 h and exogenous ethylene (ET), jasmonic acid (JA) and NaCl treatments, but repressed by H2O2 and salicylic acid (SA) treatments. Visual disease symptoms, histological observations of fungal growth and host cell death, and accumulation of H2O2 in transgenic tobacco plants indicated that CmPR1 overexpression significantly enhanced the resistance to Golovinomyces cichoracearum compared to wild type plants during PM pathogens infection, possibly due to inducing cell death and H2O2 accumulation near infected sites. The expression of PR1a was significantly induced in transgenic tobacco plants in response to G. cichoracearum, suggesting that CmPR1 overexpression positively modulates the resistance to PM via the SA signaling pathway. These findings indicate that CmPR1 is a defense response gene in C. moschata and can be exploited to develop disease-resistant crop varieties.
