Haploinsufficiency of Lipin3 leads to hypertriglyceridemia and obesity by disrupting the expression andhypertriglyceridemia and obesity by disrupting the expression and nucleocytoplasmic localization of Lipin1

Frontiers of Medicine doi: 10.1007/s11684-023-1003-0

Abstract: Lipin proteins including Lipin 1–3 act as transcriptional co-activators and phosphatidic acid phosphohydrolaseHence, we generated Lipin3 heterozygous knockout (Lipin3-heKO) mice and cultured primary hepatocytesthe overexpression and abnormal distribution of Lipin1 in cytosol and nucleoplasm.The increased expression of Lipin1 in cytosol may contribute to TG anabolism, and the decreased Lipin1in nucleoplasm can reduce PGC1α, further leading to mitochondrial dysfunction and reduced TG catabolism

Frontiers of Information Technology & Electronic Engineering 2021, Volume 22, Issue 10,   Pages 1370-1378 doi: 10.1631/FITEE.2000330

Abstract: Multicomponent oxide (GaIn)O films are prepared on (0001) sapphire substrates to realize a tunable band-gap by technology followed by thermal annealing. The optical properties and band structure evolution over the whole range of compositions in ternary compounds (GaIn)O are investigated in detail. The X-ray diffraction spectra clearly indicate that (GaIn)O films with Ga content varying from 0.11 to 0.55 have both cubic and monoclinic structures, and that for films with Ga content higher than 0.74, only the monoclinic structure appears. The transmittance of all films is greater than 86% in the visible range with sharp absorption edges and clear fringes. In addition, a blue shift of ultraviolet absorption edges from 380 to 250 nm is noted with increasing Ga content, indicating increasing band-gap energy from 3.61 to 4.64 eV. The experimental results lay a foundation for the application of transparent conductive compound (GaIn)O thin films in photoelectric and photovoltaic industry, especially in display, light-emitting diode, and solar cell applications.

Frontiers of Information Technology & Electronic Engineering 2021, Volume 22, Issue 11,   Pages 1505-1516 doi: 10.1631/FITEE.2000688

Abstract: In this era of pervasive computing, low-resource devices have been deployed in various fields. is a designed for low latency, and is suitable for pervasive computing applications. In this paper, we propose new circuit structures for components by sharing and simplifying logic circuits, to achieve the goal of using a smaller number of logic gates to obtain the same result. Based on the new circuit structures of components and the best sharing among components, we propose three new hardware architectures for . The architectures are simulated and synthesized on different programmable gate array devices. The results on Virtex-6 show that compared with existing architectures, the resource consumption of the unrolled, , and two-cycle architectures is reduced by 73, 119, and 380 slices, respectively. The architecture costs only 137 slices. The unrolled architecture costs 409 slices and has a throughput of 5.34 Gb/s. To our knowledge, for the hardware implementation of , the new architecture sets new area records, and the new unrolled architecture sets new throughput records. Therefore, the newly proposed architectures are more resource-efficient and suitable for lightweight, latency-critical applications.
