“…As shown in Figure A, the following genes were enriched in clusters: Gnas , Gprasp1 , Krt7 , Gcp4 , Esyt1 , Krt15 , Diras2 , Celf4 , Cp ; these may be the genes related to Tipe1 that regulate β cell function. The roles of Gnas , Gprasp1 , Krt7 , and Gcp4 have been reported in glycolipid metabolism, [ 41–44 ] among which Gnas plays a key role in regulating β cell function and has been listed as a candidate gene for T2D pathogenesis. [ 28,29,40 ] Krt7 is a constituent of the keratin network in mouse islets; however, Krt7 is not expressed in human pancreatic islets under basal conditions.…”

[ 45 ] Gcp4 is located in the membrane, [ 44 ] indicating an indirect interaction and regulation between Tipe1 and Gcp4. We next determined the interaction of Tipe1 with Gαs (encoded by Gnas ) or GΑSP1 (encoded by Gprasp1 ) (Figure 3B; Figure S8A, Supporting Information).…”

Inadequate β‐cell mass and insulin secretion are essential for the development of type 2 diabetes (T2D). TNF‐α‐induced protein 8‐like 1 (Tipe1) plays a crucial role in multiple diseases, however, a specific role in T2D pathogenesis remains largely unexplored. Herein, Tipe1 as a key regulator in T2D, contributing to the maintenance of β cell homeostasis is identified. The results show that the β‐cell‐specific knockout of Tipe1 (termed Ins2‐Tipe1BKO) aggravated diabetic phenotypes in db/db mice or in mice with high‐fat diet‐induced diabetes. Notably, Tipe1 improves β cell mass and function, a process that depends on Gαs, the α subunit of the G‐stimulating protein. Mechanistically, Tipe1 inhibited the K48‐linked ubiquitination degradation of Gαs by recruiting the deubiquitinase USP5. Consequently, Gαs or cAMP agonists almost completely restored the dysfunction of β cells observed in Ins2‐Tipe1BKO mice. The findings characterize Tipe1 as a regulator of β cell function through the Gαs/cAMP pathway, suggesting that Tipe1 may emerge as a novel target for T2D intervention.

Acoustic microfluidic chips, fabricated by combining lithium niobate (LiNbO3) with polydimethylsiloxane (PDMS), practically find applications in biomedicine. However, high‐strength direct bonding of LiNbO3 substrate with PDMS microchannel remains a challenge due to the large mismatching of thermal expansion coefficient at the interface and the lack of bonding theory. This paper elaborately reveals the bonding mechanisms of PDMS and LiNbO3, demonstrating an irreversible bonding method for PDMS‐LiNbO3 heterostructures using oxygen plasma modification. An in‐situ monitoring strategy by using resonant devices is proposed for oxygen plasma, including quartz crystal microbalance (QCM) covered with PDMS and surface acoustic wave (SAW) fabricated by LiNbO3. When oxygen plasma exposure occurs, surfaces are cleaned, oxygen ions are implanted, and hydroxyl groups (‐OH) are formed. Upon interfaces bonding, the interface will form niobium‐oxygen‐silicon covalent bonds to realize an irreversible connection. A champion bonding strength is obtained of 1.1 MPa, and the PDMS‐LiNbO3 acoustic microfluidic chip excels in leakage tests, withstanding pressures exceeding 60 psi, outperforming many previously reported devices. This work addresses the gap in PDMS‐LiNbO3 bonding theory and advances its practical application in the acoustic microfluidic field.

Microplastics in Malaysia's Aquatic Environment: Current Overview and Future Perspectives

Microplastic pollution has adversely affected the aquatic ecosystem, living creatures, and human health. Several studies in Malaysia have provided baseline information on the existence of microplastics in surface water, ingestion by marine life and sediment. Also, humans are exposed to microplastic due to consumption of contaminated abiotic and biotic products, such as processed seafood. Nonetheless, knowledge is still scarce among Malaysian on the potential remediation and pollution management of microplastics, which poses a significant challenge to preserve a good environmental status. Green technologies also other alternative to mitigate the contamination of microplastics for sustainable future. Hence, this review aims to provide an overview of microplastic's occurrence, fate, and implications in Malaysia's aquatic environment. Detection of microplastics from the water surface, ingestion by aquatics, and sediment samples are highlighted. Available different treatment processes toward microplastic remediation are also discussed. Additionally, the potential challenges, current perspective for plastic management in Malaysia, as well as green strategies for reducing microplastic contamination are also put forward. The goal of this work is to improve the understanding of the seriousness of microplastic contamination in aquatic environments, thus encouraging key concerns that need to be investigated further.

On the pulsating (m,c)-Fibonacci sequence

Abstract: In this paper, we study new ideas in the generalization of additive and multiplicative pulsating Fibonacci sequences. Then, we construct two types of pulsating Fibonacci sequences of the m th order. Moreover, the closed forms of the two sequences are derived by basic linear algebra.
