Authors: Jayana Rena , Fadlilah Ilma , Prasadi Oto 
Published: June 2024

Penelitian ini bertujuan untuk mengetahui karakteristik zeolit sintesis dari pemanfaatan limbah daun nipah (Nypa frutycans wurmb) dan alumunium foil bekas. Berdasarkan hasil uji FTIR menunjukkan Zeolit Sintesis Rasio 1 (ZSR-1) dan Zeolit Sintesis Rasio 2 (ZSR-2) telah memenuhi semua spektra pada daerah serapan indikator terbentuknya zeolit sintesis. Karakteristik zeolit sintesis berdasarkan SEM menunjukkan ZSR-1 masuk kategori zeolit NaX sedangkan ZSR-2 merupakan zeolit NaY. Hasil uji EDX menunjukkan ZSR-1 dan ZSR-2 merupakan jenis zeolit kaya akan alumunium dengan nilai rasio Si/Al 0,07 % untuk ZSR-1 serta 0,25 % untuk ZSR-2. Karateristik ZSR-2 lebih optimum jika dibandingkan ZSR-1. Hasil uji FTIR menunjukkan bahwa panjang gelombang ZSR-2 pada vibrasi ulur simetri internal O-Si-O/O-Al-O lebih tinggi yaitu 725,23 cm-1 jika dibandingkan ZSR-1 yang hanya 663,51 cm-1. Hal ini menunjukkan indikasi bahwa ZSR-2 memiliki rasio Si/Al lebih tinggi jika dibandingkan ZSR-1. Hal ini dikonfirmasi oleh hasil EDX yang menunjukkan hasil rasio Si/Al untuk ZSR-2 lebih besar yaitu 0,25 % jika dibandingkan rasio Si/Al dari ZSR-1 yang hanya 0,07 %. Hasil uji SEM menunjukkan Zeolit NaY (ZSR-2 berbentuk kubus) memiliki pori lebih besar dibandingkan zeolit NaX (ZSR-1 berbentuk tidak beraturan) serta pada temperatur tinggi zeolit NaY lebih stabil dan lebih aktif dibandingkan zeolit NaX. The purpose of this study was to determine the characteristics of synthetic zeolite from the utilization of nipah leaf waste (Nypa frutycans wurmb) and used aluminum foil. Based on the results of the FTIR test, it was shown that the Synthetic Zeolite Ratio 1 (ZSR-1) and the Synthetic Zeolite Ratio 2 (ZSR-2) fulfilled all the spectra in the indicator absorption area for the formation of synthetic zeolite. The characteristics of synthetic zeolite based on SEM showed that ZSR-1 was categorized as NaX zeolite, while ZSR-2 was NaY zeolite. The results of the EDX test showed that ZSR-1 and ZSR-2 were types of zeolite rich in aluminum with a Si/Al ratio of 0.07% for ZSR-1 and 0.25% for ZSR-2. The characteristics of ZSR-2 are more optimum when compared to ZSR-1. The FTIR test results showed that the wavelength of ZSR-2 in the stretching vibration of internal symmetry O-Si-O/O-Al-O was higher, namely 725,23 cm-1 compared to ZSR-1 which was only 663,51 cm-1. This indicates that ZSR-2 has a higher Si/Al ratio than ZSR-1. This was confirmed by the EDX results which showed that the Si/Al ratio for ZSR-2 was greater, namely 0.25%, compared to the Si/Al ratio for ZSR-1 which was only 0.07%. SEM test results showed that NaY Zeolite (cuboid ZSR-2) has larger pores than NaX zeolite (ZSR-1 irregular shape) and at high temperatures NaY zeolite is more stable and more active than NaX zeolite.

Published: June 2024

AbstractThis crossover study evaluated DNA methylation changes in human salivary samples following single sprint interval training sessions performed in hypoxia, with blood flow restriction (BFR), or with gravity‐induced BFR. Global DNA methylation levels were evaluated with an enzyme‐linked immunosorbent assay. Methylation‐sensitive restriction enzymes were used to determine the percentage methylation in a part of the promoter of the gene‐inducible nitric oxide synthase (p‐iNOS), as well as an enhancer (e‐iNOS). Global methylation increased after exercise (p < 0.001; dz = 0.50). A tendency was observed for exercise × condition interaction (p = 0.070). Post hoc analyses revealed a significant increase in global methylation between pre‐ (7.2 ± 2.6%) and postexercise (10.7 ± 2.1%) with BFR (p = 0.025; dz = 0.69). Methylation of p‐iNOS was unchanged (p > 0.05). Conversely, the methylation of e‐iNOS increased from 0.6 ± 0.4% to 0.9 ± 0.8% after exercise (p = 0.025; dz = 0.41), independently of the condition (p > 0.05). Global methylation correlated with muscle oxygenation during exercise (r = 0.37, p = 0.042), while e‐iNOS methylation showed an opposite association (r = −0.60, p = 0.025). Furthermore, p‐iNOS methylation was linked to heart rate (r = 0.49, p = 0.028). Hence, a single sprint interval training increases global methylation in saliva, and adding BFR tends to increase it further. Lower muscle oxygenation is associated with augmented e‐iNOS methylation. Finally, increased cardiovascular strain results in increased p‐iNOS methylation.

Published: June 2024

AbstractHypertension disproportionately affects African Americans and is a risk factor for Alzheimer's disease (AD). We investigated the relationship of blood pressure (BP) with medial temporal lobe (MTL) dynamic network flexibility (a novel AD biomarker) and cognitive generalization in older African Americans. In a cross‐sectional study, 37 normotensive (systolic BP <130 mmHg, 82.5% F, 64.4 ± 4.9 years; 14.3 ± 2.1 years of education) versus 79 hypertensive (systolic BP ≥130 mmHg, 79.5% F, 66.8 ± 4.1 years; 14.0 ± 0.2 years of education) participants were enrolled. All participants completed a 10‐min resting‐state functional magnetic resonance imaging scan to assess MTL dynamic network flexibility and two generalization tasks to assess cognition. Anthropometrics and aerobic fitness (via 6‐min walk test) were also determined. There was no difference in BMI (29.7 ± 6.4 vs. 31.9 ± 6.3 kg/m2, p = 0.083) or aerobic fitness (15.5 ± 2.6 vs. 15.1 ± 2.6 mL/kg/min; p = 0.445) between normotensive and hypertensive groups. However, normotensive participants had higher MTL dynamic network flexibility compared to hypertensive participants (0.42 ± 0.23 vs. 0.32 ± 0.25 mL, p = 0.040), and this was associated with higher mean arterial blood pressure (r = −0.21, p = 0.036). Therefore, hypertensive older African Americans demonstrated lower MTL dynamic network flexibility compared to their normotensive counterparts independent of BMI and aerobic fitness. Further studies are required to determine how blood pressure mediates AD risk in African Americans.

Published: June 2024

AbstractJuly 2023 has been confirmed as Earth's hottest month on record, and it was characterized by extraordinary heatwaves across southern Europe. Field data collected under real heatwave periods could add important evidence to understand human adaptability to extreme heat. However, field studies on human physiological responses to heatwave periods remain limited. We performed field thermo‐physiological measurements in a healthy 37‐years male undergoing resting and physical activity in an outdoor environment in the capital of Sicily, Palermo, during (July 21; highest level of local heat‐health alert) and following (August 10; lowest level of local heat‐health alert) the peak of Sicily's July 2023 heatwave. Results indicated that ~40 min of outdoor walking and light running in 33.8°C Wet Bulb Globe Temperature (WBGT) conditions (July 21) resulted in significant physiological stress (i.e., peak heart rate: 209 bpm; core temperature: 39.13°C; mean skin temperature: 37.2°C; whole‐body sweat losses: 1.7 kg). Importantly, significant physiological stress was also observed during less severe heat conditions (August 10; WBGT: 29.1°C; peak heart rate: 190 bpm; core temperature: 38.48°C; whole‐body sweat losses: 2 kg). These observations highlight the physiological strain that current heatwave conditions pose on healthy young individuals. This ecologically‐valid empirical evidence could inform more accurate heat‐health planning.

Towards a Protective Condictio? The Bank M Case in the Prism of Restitutory Remedies: A Reconstructive Proposal
Authors: Corletto Francesca 
Published: June 2024

Abstract
The aim of the paper is to provide a reconstructive reading of the case Bank M in the light of the core principles of the system of protection established by Directive 93/13, as well as, more generally, the regulation of restitutionary remedies derivable from national laws and the general principles of EU law. The analysis takes particularly into account the Italian civil lawyer’s point of view, as before the advent of Bank M, the Italian Supreme Court had already ruled on the same subject, establishing an unprecedented version of the condictio: an asymmetrical condictio, which has been defined, with a significant expression, as ‘protective condictio indebiti’. Since both Courts allow the non professional party to pursue restitutory claims to which the professional party is not entitled as well, one might be led to believe that the same starting question was resolved in the same way in both cases, and therefore that, as a result of the case Bank M, a ‘protective condictio indebiti’ such as that established by the Italian Supreme Court can be said to have been established (also) in European contract law. However, for the reasons to be explained below, it is believed that the CJEU did not intend to introduce a unilateral or asymmetrical claim for recovery of undue payment, but merely permitted the consumer to demand what, under domestic law, he or she would have obtained by exercising the general action of unjust enrichment. It will be seen how the general content of restitutory protection is articulated in the system established by the UCTD, in the light of the most relevant ECJ’s case-law on this subject, with the ultimate aim of verifying whether the ‘protective condictio indebiti’ outlined by Italian case-law can enter fully into European contract law.156
Moisture distribution change and quality characteristics of ultrasound enhanced heat pump drying on carrot
Authors: Wang Xueqing , Han Meng , Peng Chengnuo , Xie Anguo , Fan Xiaoyan , Liu Yunhong 
Published: June 2024

Abstract
The study aims at investigating the impact of ultrasound enhancement on the water change and quality characteristics of dried carrots by heat pump drying (HPD). The results showed that ultrasound had obvious strengthening effect on the drying and dehydration process of HPD, but there was an attenuation effect of ultrasound in the propagation process of materials, and the magnetic resonance imaging results could visually demonstrate the change and migration of moisture inside carrot slices. Higher drying temperature and ultrasonic power could cause more micropores and higher content of polyphenols, flavonoids and niacin of carrot slices. Conversely, the elevated drying temperature reduced rehydration ratio. β-carotene content showed a trend of increasing first and then decreasing due to excessive temperature and ultrasonic power. Based on AHP-CRTITC method, the highest comprehensive score was attained at drying temperature of 60 °C and ultrasonic power of 80 W. Therefore, the reinforcement effect of ultrasound on HPD process could significantly enhance dehydration rate and improve product quality.
Questionable accuracy of four ELISA kits in serum Netrin-1 measurement
Authors: Cai Minqi , Zheng Qian , Chen Yiqiang , Liu Siyuan , Zhu Huimin , Bai Bing 
Published: June 2024

Abstract

Objectives
Altered serum Netrin-1 levels have been widely reported in cancer and other clinical diseases and they are often measured by commercial ELISA kits. However, we found the questionable results using these kits and therefore performed this simple study to evaluate their accuracy in detection of serum Netrin-1.

Methods
Four commonly used commercial kits were collected. The kit standards were serially diluted or spiked into serum samples. The cells with confirmed expression of Netrin-1 and their culture medium, as well as the Netrin-1 controls of each kit were used for the kits to detect. The cell lysate samples and the kit controls were also blotted on a nitrocellulose membrane for detection antibodies of each kit to probe.

Results
Detection of the Netrin-1 standards in serum by each kit were all affected. Only one kit was able to detect Netrin-1 in the cell lysate or medium. No ELISA kits could detect all Netrin-1 controls of the four kits. None of the detection antibodies correctly probed Netrin-1 in the dot blot.

Conclusions
The accuracy of these four Netrin-1 ELISA kits is under question. Reported serum Netrin-1 levels based on measurements by these kits need be carefully interpreted.
Enhancing cooperativity of molecular J-aggregates by resonantly coupled dielectric metasurfaces
Authors: Marangi Marco , Wang Yutao , Wu Mengfei , Tjiptoharsono Febiana , Kuznetsov Arseniy I. , Adamo Giorgio , Soci Cesare 
Published: June 2024

Abstract
J-aggregates are supramolecular assemblies of dyes exhibiting strong absorption and fluorescence with narrow linewidths, as well as large optical nonlinearities, induced by the formation of largely delocalized molecular excitons. The degree of cooperativity achievable in J-aggregates ensembles, however, is limited by local disorder and thermally induced decoherence effects. A way to overcome these limitations and increase molecular exciton delocalization and coherence is to couple the ensemble of highly ordered molecular dipoles to a common electromagnetic mode in an optical resonator. In this work, we use dielectric metasurfaces to alter the radiative properties of coupled J-aggregate films and demonstrate a 5-fold Purcell enhancement of the luminesce intensity and narrowing of the emission directivity down to ∼300 mrad around the normal. These results highlight the potential of designer dielectric metasurfaces to foster the emergence of cooperative phenomena in excitonic systems, including optical nonlinearities and superradiance.

Abstract

Objectives
There are few data on Pressurized IntraPeritoneal Aerosol Chemotherapy with cisplatin and doxorubicin (PIPAC C/D) in women with primary unresectable or recurrent platinum-resistant peritoneal metastasis (PM) from ovarian cancer (OC). We evaluated survival, histological and cytological response, Quality of Life (QoL) and toxicity after PIPAC C/D in these patients.

Methods
Retrospective analysis of patients from the prospective PIPAC-OPC1 and -OPC2 studies. The histological response was evaluated by the Peritoneal Regression Grading Score (PRGS). QoL questionnaires were collected at baseline and after third PIPAC or 60 days. Adverse events were collected until 30 days after the last PIPAC. Demographic and survival data were analysed based on intention to treat. Response, QoL and toxicity were analysed per protocol (≥1 PIPAC).

Results
Twenty-nine patients were included. Five patients (17 %) were non-accessible at PIPAC 1. One patient was excluded due to liver metastases at PIPAC 1. Thus, 23 patients had 76 PIPACs (median 2, range 1–12). Median overall survival was 8.2 months (95 % CI 4.4–10.3) from PIPAC 1. Biopsy data were available for 22 patients, and seven (32 %) patients had a major/complete histological response (PRGS≤2) at PIPAC 3. No cytological conversions were registered. Symptoms and function scores worsened, while emotional scores improved. Three patients had severe adverse reactions (two ileus, one pulmonary embolism); no life-threatening reactions or treatment-related mortality was observed.

Conclusions
PIPAC C/D was feasible and induced histological regression in a substantial proportion of patients with platinum-resistant PM from OC. Larger studies are needed to evaluate impact on survival.
Botanical Portraits: On a 1935 Argentinean Book by Ilse von Rentzell with Photographs by Anatole Saderman
Authors: Pestarino Julieta 
Published: June 2024

Abstract
In 1935, the Argentine-German botanist Ilse von Rentzell (1893–1985) published the book “Maravillas de nuestras plantas indígenas y algunas exóticas” (Wonders of our Indigenous Plants and Some Exotic Plants) in Buenos Aires, Argentina, illustrated with photographs taken by the Russian photographer Anatole Saderman (1904–1993). The publication of this book was entirely selffinanced by Von Rentzell herself, and it is one of the first in Argentina to include such a large number of photographs with this much prominence. The collaborative photographic work developed by these authors goes beyond the images included in the book. Working together, they created a corpus of photographs that each of them used in the following years to enhance their personal careers. At the time, these photographs of plants represented a break in Argentine photography, building bridges with the genealogy of botanical photographic publications in other parts of the world.
