Instruct 3D-to-3D: Text Instruction Guided 3D-to-3D conversion

We propose a high-quality 3D-to-3D conversion method, Instruct 3D-to-3D. Our method is designed for a novel task, which is to convert a given 3D scene to another scene according to text instructions. Instruct 3D-to-3D applies pretrained Image-to-Image diffusion models for 3D-to-3D conversion. This enables the likelihood maximization of each viewpoint image and high-quality 3D generation. In addition, our proposed method explicitly inputs the source 3D scene as a condition, which enhances 3D consistency and controllability of how much of the source 3D scene structure is reflected. We also propose dynamic scaling, which allows the intensity of the geometry transformation to be adjusted. We performed quantitative and qualitative evaluations and showed that our proposed method achieves higher quality 3D-to-3D conversions than baseline methods.Comment: Project page: https://sony.github.io/Instruct3Dto3D-doc

Three-year-old traumatic liver injury patient treated successfully using transcatheter arterial embolization

Introduction Liver injury is the most vulnerable to blunt abdominal trauma. Diagnostic evaluation and treatment of blunt liver trauma in children have changed essentially over the last decades. Presentation of case A 3-year-old girl, weighing 10 kg was run over by a car and admitted to our hospital.　Due to the liver injury and increased intra-abdominal hemorrhage confirmed by computed tomography, emergent transcatheter arterial embolization (TAE) was performed. Hemostasis was successfully obtained without complications. The patient had a good postoperative course and was discharged on the 9th day after admission. Discussion To the best of our knowledge, this case is the youngest and lowest weight emergency TAE success cases of childhood liver injury. TAE is an alternative to laparotomy and a useful procedure to accomplish nonsurgical management in adult who are hemodynamically stable and have no other associated injury requiring laparotomy. On the other hand, TAE is considered to have some complications in child cases because of the small diameter of the artery and the tendency to spasm. Our case showed that TAE can be a safe option for emergency hemostasis in pediatric trauma cases weighing 10 kg. Conclusion Emergency physicians must be aware that radiological intervention is an important adjunct to management of childhood liver injury

Evolution of Nonlinear Acoustics during Creep in ASME Grade 91 Steel Welded Joint

ASME Grade 91 (9Cr-1Mo-MnVNb) has been used for boiler components in ultra-supercritical (USC) thermal power plants at approximately 873 K. The creep life of the welded joints in this steel decreased as a result of Type IV creep damage that forms in the heat-affected zone (HAZ) under long-term use at high temperatures [1]. In this study, we investigated the relationship between microstructural change and the evolutions of two nonlinear acoustic characterizations with electromagnetic acoustic resonance (EMAR) [2] throughout the creep life in the welded joints and the correlation between two nonlinear acoustic characterizations. One was resonant frequency shift [3] and other three-wave mixing [4, 5]. EMAR was a combination of the resonant acoustic technique with a non-contact electromagnetic acoustic transducer (EMAT) [2]. We used a bulk-wave EMAT, which transmits and receives shear wave propagating in thickness direction of a plate specimen. Creep tests of thick welded joints specimens were interrupted at several time steps at 873 K and 90 MPa. Two nonlinear acoustic parameters and ultrasonic attenuation decreased from the start to 20% of creep life. They gradually increased from 50% of creep life to rupture. We interpreted these phenomena in terms of dislocation recovery, recrystallization, and restructuring related to the initiation and growth of creep void, with support from the SEM and TEM observation. This noncontact resonance-EMAT measurement can monitor the evolution of nonlinear acoustics throughout the creep life and has a potential to assess the Type IV creep damage advance and to predict the creep life of high Cr ferritic heat resisting steels

RN7SL1 may be translated under oncogenic conditions

Hara T., Meng S., Tsuji Y., et al. RN7SL1 may be translated under oncogenic conditions. Proceedings of the National Academy of Sciences of the United States of America 121, (2024); https://doi.org/10.1073/pnas.2312322121.RN7SL1 (RNA component of signal recognition particle 7SL1), a component of the signal recognition particle, is a non-coding RNA possessing a small ORF (smORF). However, whether it is translated into peptides is unknown. Here, we generated the RN7SL1-Green Fluorescent Protein (GFP) gene, in which the smORF of RN7SL1 was replaced by GFP, introduced it into 293T cells, and observed cells emitting GFP fluorescence. Furthermore, RNA-seq of GFP-positive cells revealed that they were in an oncogenic state, suggesting that RN7SL1 smORF may be translated under special conditions

CXCL14 Deficiency in Mice Attenuates Obesity and Inhibits Feeding Behavior in a Novel Environment

BACKGROUND: CXCL14 is a chemoattractant for macrophages and immature dendritic cells. We recently reported that CXCL14-deficient (CXCL14(-/-)) female mice in the mixed background are protected from obesity-induced hyperglycemia and insulin resistance. The decreased macrophage infiltration into visceral adipose tissues and the increased insulin sensitivity of skeletal muscle contributed to these phenotypes. METHODOLOGY/PRINCIPAL FINDINGS: In this study, we performed a comprehensive study for the body weight control of CXCL14(-/-) mice in the C57BL/6 background. We show that both male and female CXCL14(-/-) mice have a 7-11% lower body weight compared to CXCL14(+/-) and CXCL14(+/+) mice in adulthood. This is mainly caused by decreased food intake, and not by increased energy expenditure or locomotor activity. Reduced body weight resulting from the CXCL14 deficiency was more pronounced in double mutant CXCL14(-/-)ob/ob and CXCL14(-/-)A(y) mice. In the case of CXCL14(-/-)A(y) mice, oxygen consumption was increased compared to CXCL14(+/-)A(y) mice, in addition to the reduced food intake. In CXCL14(-/-) mice, fasting-induced up-regulation of Npy and Agrp mRNAs in the hypothalamus was blunted. As intracerebroventricular injection of recombinant CXCL14 did not change the food intake of CXCL14(-/-) mice, CXCL14 could indirectly regulate appetite. Intriguingly, the food intake of CXCL14(-/-) mice was significantly repressed when mice were transferred to a novel environment. CONCLUSIONS/SIGNIFICANCE: We demonstrated that CXCL14 is involved in the body weight control leading to the fully obese phenotype in leptin-deficient or A(y) mutant mice. In addition, we obtained evidence indicating that CXCL14 may play an important role in central nervous system regulation of feeding behavior
