ABSTRACT The commensal bacterium Alistipes shahii is a core microbe of the human gut microbiome and its abundance negatively correlated with inflammatory bowel diseases (IBDs). However, fundamental role in regulating response remains unknown. Using dextran sulfate sodium (DSS)-induced colitis mouse model, we examined effect A. strain As360 intervention on host found that alleviated disease activity index, colon shortening, colonic histopathological lesion. levels tight junction proteins...

Abstract Sea fog is frequently observed over the Yellow Sea, with an average of 50 days on Chinese coast during April–July. The season characterized by abrupt onset in April southern Shandong Peninsula and abrupt, basin-wide termination August. This study investigates mechanisms for such steplike evolution that inexplicable from gradual change solar radiation. From March to northwestern a temperature inversion forms layer 100–350 m above sea surface, prevailing surface winds switch...

Abstract A concise and objective definition of monsoon rainy season characteristics is proposed for worldwide regions. The result highlights six major summer domains the mean dates local onset, peak withdrawal phases season. onset occur progressively later poleward in continental but primarily eastward oceanic retreats equatorward over length decreases shorter can also be found outskirts warm water. Some exceptions exist terms season, e.g. westward advance North Africa an apparently...

A new cocculinid species collected from a dolphin skull in the East China Sea is described and assigned to genus Cocculina Dall, 1882. This species, delphinicula sp. nov., has medium sized, depressed shell sculptured with regularly spaced concentric growth lines fine radial threads. The radula formula of (ca. 20)+5+1+5+(ca. 20) vestigial rachidian, lateral 1 weak but well defined, having an outline that frequently terminates into small beak-like cusp, laterals 2 3 3–4 cusps, 4 large primary...

During research dives by the submersible ROV Faxian, two margaritid species were collected in Okinawa Trough and Manus Back-Arc Basin. In present study, we describe illustrate them as Margarites similis sp. nov. manusensis nov., respectively. The generic allocation is based on shell morphology radula features. Phylogenetic reconstruction using cytochrome c oxidase subunit I (COI) gene also supports their placements within Margarites.

During an investigation carried out by the Institute of Oceanology, Chinese Academy Sciences (IOCAS), two living buccinid specimens were collected from a deep-sea methane seep area in South China Sea. Observations shell, gross anatomy and radular morphology reveal that they represent undescribed species genus Enigmaticolus. In this paper, we describe illustrate as Enigmaticolus inflatus sp. nov. The new is general shell shape most similar to marshalli Fraussen & Stahlschmidt, 2016...

Abstract. Marine aerosol affects the global energy budget and regional weather. The production of marine is primarily driven by wind at sea–air interface. Previous studies have explored effects on aerosol, mostly examining relationships between optical depth (AOD) surface speed. In this paper, utilizing synergy observations from Aeolus, properties 355 nm instantaneous co-located speeds remote oceans are investigated two vertical layers (within above atmospheric boundary layer (MABL))....

Dental pulp stem cells hold significant prospects for tooth regeneration and repair. However, a comprehensive understanding of the molecular differences between dental (DPSC, from permanent teeth) human exfoliated deciduous teeth (SHED, remains elusive, which is crucial optimizing their therapeutic potential. To address this gap, we employed novel data-independent acquisition (DIA) proteomics approach to compare protein expression profiles DPSC SHED. Based on nano-LC-MS/MS DIA proteomics,...

The microphysics and visibility (Vis) of a sea fog event with precipitation were measured at the Baguan Hill Meteorological Station (BGMS) (36.07° N, 120.33° E; 86 m above level) from 27 June to 28 2022. duration process was 880 min. mean value number concentration (Nd) 190.62 cm−3, liquid water content (LWC) 0.026 g m−3. Small droplets contributed 81% Nd had greater impact on attenuation, while larger accounted for 58% total LWC. observed droplet size distribution (DSD) better represented...

The Northwest Pacific (NWP) is a region with the highest frequency of sea fog occurrence and most widely distributed area in world oceans. prone located mid-latitudes where ocean navigations are getting more active. Sea heavy obstacles for navigation due to low visibility fog. techniques forecasting NWP still remains unsatisfactory compared marginal seas so far. Using observations from ICOADS ERA5 data 2013 2021, this study tried make prediction model based on machine learnings....

The Okhotsk Sea is renowned as one of the world's most foggy regions. Previous studies have identified that sea fog occurring under south winds is mainly advection fog. However, formation mechanism north remains unclear. On August 21, 2019, research vessel "Xiangyanghong 01" observed a phenomenon where low clouds transformed into in waters Kuril Islands north wind . Analysis shipborne observations, reanalysis data, and simulation results...

Abstract Effects of the sea surface temperature (SST) front along East China Sea Kuroshio on winds at different time scales are investigated. In winter and spring, climatological vector wind is strongest SST while scalar speed reaches a maximum warm flank collocated with difference between air (SST − SAT). The distinction due to change in relative importance two physical processes SST–wind interaction scales. front–induced level pressure (SLP) adjustment (SF–SLP) contributes strong above...

Abstract An extended three-dimensional variational data assimilation (3DVAR) method based on the Weather Research and Forecasting Model (WRF) is developed to assimilate satellite-derived humidity from sea fog at its initial stage over Yellow Sea.
