Using ambient seismic noise to monitor ocean bottom pressure
Authors: Luo Bingxu , Zhang Shuo , Takeuchi Nozomu , Lumley David , Zhu Hejun 
Published: March 2024

Ambient seismic noise (ASN) recorded by ocean bottom seismometers allows
us to perform coda wave interferometry without using active sources. We
analyzed two-year ASN recordings from five ocean bottom stations in the
northwestern Pacific Ocean basin (depth > 5,500 m), and
measured the relative velocity variation (δv/v)
near the seafloor. The most important finding is an extremely low
variation in δv/v (around
-0.05\%), which likely responds to a significant
pressure drop at sea level and subsequently affects an anomaly at the
ocean bottom (over -400 Pa) in December 2013. Furthermore, several major
phases of the velocity change show delayed-correlation with the sea
level pressure variations. A poroelastic simulation with adjusted ocean
bottom variables supports the pressure factor mainly drives the
variation in δv/v. Our study suggests the
potential use of seismic signals to monitor oceanic and atmospheric
processes by tracking variations in the oceanic pressure field.

Published: March 2024

Kawasan Indo Pasifik menjadi penyumbang sampah plastik laut terbesar dunia. Sampah plastik ini terbawa aliran sungai besar negara Asia Tenggara yang kemudian membendung di Samudera Hindia dan Pasifik. Permasalahan sampah plastik laut cukup kompleks karena menyebabkan kerusakan lingkungan, dampak ekonomi, penurunan kesehatan biota laut, dan mengancam kesehatan manusia yang mengonsumsi. Jepang dan ASEAN bekerjasama untuk mengatasi masalah ini dalam salah satu proyek Joint Statement Japan Cooperation on ASEAN Outlook on the Indo Pacific (AOIP). Penelitian ini berfokus pada kerjasama Jepang dan ASEAN dalam mengatasi sampah plastik laut (Plastic Marine Debris) dalam teori kerjasama keamanan maritim dan Regional Security Complex. Penelitian ini menggunakan metode kualitatif dengan tipe penelitian deskriptif yang menghasilkan kerjasama Jepang-ASEAN berupa pelatihan, pengelolaan limbah, promosi penanggulangan sampah laut, koordinasi berbagai pihak, dan aksi kolaborasi UNEP. Kerjasama ini melahirkan penguatan kesadaran, edukasi, dan (amity) Jepang-ASEAN yang mendukung keamanan maritim dan ekonomi kawasan Indo Pasifik. The Indo Pacific region is the world's larger contributor to marine plastic debris. This plastic waste is carried by the flow of large rivers of Southeast Asian countries which then stem in the Indian and Pacific Oceans. The problem of marine plastic debris is quite complex because it causes environmental damage, economic impact, decreases the health of maritime biota, and threatens the health of humans who consume. Japan and ASEAN are working together to address this issue in one of the Joint Statement Japan Cooperation on ASEAN Outlook on the Indo Pacific (AOIP) projects. This research focuses on Japan and ASEAN cooperation in overcoming plastic marine debris in the theory of maritime security cooperation and Regional Security Complex. This research uses qualitative methods with descriptive research types that result in Japan-ASEAN cooperation in athe form of training, waste management, promotion of marine debris prevention, coordination of various parties, and UNEP collaborative actions. This cooperation resulted in the strengthening of Japan-ASEAN awareness, education, and (amity) that supports the maritime and economic security of the Indo Pacific region.
Information about life expectancy related to obesity is most important to cat owners when deciding whether to act on a veterinarian's weight loss recommendation
Authors: Sutherland Katja A. , Coe Jason B. , Groves Catherine N. H. , Shepherd Megan L. , Grant Lauren E. 
Published: March 2024

Abstract

OBJECTIVE
To determine the relative importance of information communicated to cat owners during veterinarian-client obesity-related conversations.

SAMPLE
Cat owner participants recruited via snowball sampling.

METHODS
A cross-sectional online questionnaire was distributed to cat owners who owned cats of any weight status. A discrete choice experiment design was used to determine the relative importance of obesity-related attributes to cat owners when receiving information from a veterinarian.

RESULTS
A total of 1,095 questionnaires were analyzed. Participating cat owners resided primarily in Canada and the US. Impact on life expectancy was the most important attribute that would encourage participants to pursue weight management for a cat with obesity (relative importance, 32.66%), followed by change to cost of food (20.40%), future quality of life (20.38%), future mobility (14.40%), and risk of developing diabetes (12.15%).

CLINICAL RELEVANCE
Findings suggest that cat owners consider the impact on life expectancy to be most important when considering whether to follow a veterinarian's recommendation for their cat to lose weight. When veterinary professionals are communicating about obesity in practice, there is the potential to increase owner engagement in weight management efforts for cats by emphasizing the obesity-related information owners prefer to receive.
The role of TIM3+ NK and TIM3- NK cells in the immune pathogenesis of severe aplastic anemia
Authors: Ding Shaoxue , Zhang Tian , Lei Yingying , Liu Chunyan , Liu Zhaoyun , Fu Rong 
Published: March 2024

Abstract

Background
Natural killer (NK) cells play important immunoregulatory roles in the immune pathogenesis of severe aplastic anemia (SAA). Our previous research showed that SAA caused a decrease in T cell immunoglobulin mucin-3 (TIM3) expression on NK cells. Here we investigated the expression of surface receptors, and the cytotoxicity of peripheral TIM3+ NK and TIM3- NK cells in patients with SAA.

Methods
The expressions of surface receptors and cytoplasmic protein of TIM3+ NK and TIM3- NK cells from peripheral blood were detected by FCM. The functions of mDCs, and apoptosis rate of K562 cells after co-culture with TIM3+ NK and TIM3- NK cells were maesured by FCM. Westren-blot was used to detect the changes of TIM3+ NK and TIM3- NK signaling pathway proteins (AKT, P-AKT) and compare the functional activity of the two groups.

Results
Activating receptors NKG2D and Granzyme B were higher, while inhibiting receptors NKG2A, CD158a and CD158b were lower on TIM3- NK cells compared with TIM3+ NK cells in patients with SAA. In SAA, the expression of CD80 and CD86 on mDCs (Myeloid dendritic cells) was significantly decreased after incubation with TIM3- NK cells. The apoptosis rate (AR) of K562 cells was significantly increased after being incubated with TIM3- NK cells in SAA. The level of signal pathway protein AKT of TIM3- NK cells in SAA was similar to that of TIM3+ NK cells, and the levels of P-AKT and P-AKT/AKT ratio of TIM3- NK cells were significantly higher than those of TIM3+ NK cells.

Conclusions
Therefore, TIM3 exerts its inhibitory effect on NK cells and participates in the immune pathogenesis of SAA. Low expression of TIM3 contributes to the enhancement of NK cell activity which in turn inhibits the immune activation state of SAA and improves the disease state. Our research may aid the development of new therapeutic strategies based on TIM3-NK cells infusion for the treatment of SAA.
Spatiotemporal analysis of the effects of exercise on the hemodynamics of the aorta in hypertensive rats using fluid-structure interaction simulation
Authors: Wang Yueshen , Yu Haiyi , Shi Quanyou , Xu Ming , Gao Wei 
Published: March 2024

Abstract

Background and Objective
Hemodynamic changes that lead to increased blood pressure represent the main drivers of organ damage in hypertension. Prolonged increases to blood pressure can lead to vascular remodeling, which also affects vascular hemodynamics during the pathogenesis of hypertension. Exercise is beneficial for relieving hypertension, however the mechanistic link between exercise training and how it influences hemodynamics in the context of hypertension is not well understood.

Methods
n exercise model was developed using spontaneously hypertensive rats (SHR) subject to a 12-week treadmill training regime. The heart rates and blood pressures of rats were measured using the tail cuff method, while micro-computed tomography (CT) scanning was used to develop three-dimensional structures of rat aorta, and ultrasound was used to detect rat aortic blood flow and changes to vessel wall structures. Computational fluid dynamics (CFD) and fluid-structure interaction (FSI) models were used to simulate and measure hemodynamic parameters of the rat aortic vessels. In parallel, Masson staining was performed on fixed samples of blood vessels to investigate collagen volume fraction. Hypertensive rats in the sedentary and long-term exercise training groups were subjected to a single bout exercise training, and their aortic hemodynamic parameters were analyzed before, 5 min, 24 h, and 72 h after the single bout exercise.

Results
Of the two models, in comparison to actual ultrasonic measurement values recorded, we found that numerical simulation results from the FSI model could more accurately model blood flow in the ascending aorta of hypertensive rats, compared to the CFD model. Moreover, longterm exercise training improved local hemodynamic parameters of blood vessels, and led to improvements in adverse hemodynamic features documented, including time-averaged wall shear stress (TAWSS), oscillatory shear index (OSI), and relative residence time (RRT). Longterm exercise training of SHR also improved local vascular collagen deposition in the aorta, while improvements in vascular remodeling were also correlated with favorable hemodynamic parameters. Compared with sedentary SHR, signals for low TAWSS regions of the aortic arch in SHR on the long-term exercise regime shifted to the position of the ascending aorta after a single bout of exercise.

Conclusions
This study demonstrates that FSI is informative to study the spatiotemporal effects of long-term exercise training on hemodynamic changes within the aortas of hypertensive rats, and that long-term exercise is beneficial through its effects to modulate vascular hemodynamics in hypertension.
