Tri-modal death distribution towards personalized management of intraductal papillary neoplasm of the bile duct patients:Every story has its own conclusion

The concept of intraductal papillary neoplasm of the bile duct(IPNB)has gained recognition as a discrete entity[1,2],possessing many features including multiplicity[3,4],mucin production[3],slow progression[3,5],various morphology[6,7],easy sloughing and seeding[8],and having unique risk factors[2,9-11].We have previously proposed a morphologic classification[6]and a progression model of IPNB[12].

Comment on:Evaluation of retinal and choroidal thickness changes in overweight and obese adults without ocular symptoms by swept-source optical coherence tomography

Dear Editor,We have read with interest the article by Li et al[1].In the response to this article[1]which is a well thought out and written paper,I would like to draw attention to some critical points in this study and add some comments to the results and the conclusion of the study which authors have detected.In the Li et al’s[1]study,it is detected that,choroidal thickness is significantly negatively correlated with body mass index(BMI)and choroidal thickness is decreased in people with overweight or obesity.

People-Foundation of a State

Only when the foundation is strong will the state be safe and stable.THE concept that"the people are the foundation of a state"is the best expression of the people-centered philosophy of ancient China.Past Chinese sages and philosophers reached this conclusion in their study of state governance amid the rise and fall of dynasties over thousands of years.Based on the belief that the people's support of state power is vital for its success,this precept has inspired policies and practices aimed at nurturing,benefiting and enriching the people throughout Chinese history.

Osteomodulin downregulation is associated with osteoarthritis development

Abnormal subchondral bone remodeling leading to sclerosis is a main feature of osteoarthritis(OA), and osteomodulin(OMD), a proteoglycan involved in extracellular matrix mineralization, is associated with the sclerotic phenotype. However, the functions of OMD remain poorly understood, specifically in vivo. We used Omd knockout and overexpressing male mice and mutant zebrafish to study its roles in bone and cartilage metabolism and in the development of OA. The expression of Omd is deeply correlated with bone and cartilage microarchitectures affecting the bone volume and the onset of subchondral bone sclerosis and spontaneous cartilage lesions. Mechanistically, OMD binds to RANKL and inhibits osteoclastogenesis, thus controlling the balance of bone remodeling. In conclusion, OMD is a key factor in subchondral bone sclerosis associated with OA. It participates in bone and cartilage homeostasis by acting on the regulation of osteoclastogenesis. Targeting OMD may be a promising new and personalized approach for OA.

Corrigendum to“Moult intensity constraints along the complete moult sequence of the House Sparrow(Passer domesticus)”[Avian Res.14(2023)100125]

In the original version of this article,we published a figure showing a gap in the confidence intervals for body and tail due to data paucity for mid stages of moult progress.Here,we amended this problem adding data from the 2023 moulting season,during which we obtained 139 moult records from 98 individuals.The final sample size used for plotting these results are shown in the caption below.This amendment corroborates the conclusion already stated:body moult does not seem to be under physiological constraints,although primary moult appears to be tightly controlled to reduce aerodynamic losses.

Listening to the Whispers of the Universe–Detection of nHz gravitational wave background

Gravitational waves propagating at nanohertz frequencies?Do they exist?Yes.Four observational networks,from China,Australia,Europe-India,and USA,respectively,simultaneously answered on June 29,releasing results from their independent observations in the extremely low waveband of nanohertz.Consistent with each other,the results arrive at a common conclusion:our planet is immersed in a wavy spacetime ruffled by overlapping low-tone ripples.FAST,the Five-hundred-meter Aperture Spherical radio Telescope of China,is among the many giant telescopes that have played a key role in the search for this low-pitch voice.They are not the real detectors,though.

Research on Economic Impact of Super Rice on Rice Growers and Contribution to Food Security

Super rice is an essendal part of China＇s rice production. Through survey on actual situation of 1568 households of rice growers in Heilongjiang, Hunan and Zhejiang provinces, this paper focused on influence of super rice development on increase of China＇s grain yield, influence on increase of rice growers＇ economic in- come, difference in production cost and profit between the North and the South, as well as profit percentage of super rice in production, processing, and sales. It obtained following results： rice price determines rice growers＇ income; expansion of super rice extension area plays a great role in increase of China＇s grain yield; by 2015 and 2020, keeping the yield of other crops not changed, merely the extension of super rice can increase grain for 5 million tons and 11 million tons separately; super rice significantly increases rice growers＇ economic income; for production cost of super rice, the South is higher than the North, and the profit ratio of cost is up to 35.54% on average; with respect of profit in production, processing, and sales, the ratio is 1：2：1.5; with the yield of other crops unchanged, every increase of 1% in area percentage of super rice to rice will additionally produce 1 million tons of grain for China, which is equivalent to saving the yield of 133 300 hm2 farmland and can additional feed 3.5 million people. In view of importance of super rice production, at the same time of strengthening research on super rice variety, it is required to accelerate expanding production area of super rice in suitable areas. Since the development of super rice can support China＇s ration demand of increasing population, China should make effort to realize ＂one yuan for one mu＂ financial subsidy for super rice of main grain production provinces and counties. Besides, China should establish special financial plan for extension of super rice.

CRETACEOUS-TERTIARY DESERTS IN SOUTHWESTERN CHINA AND DESERT SEDIMENTOLOGY

The special issue deals with the Cretaceous-Tertiary deserts in southwestern China and relevant sedimentological problems about deserts. The study area is located between 101°10＇- 107°00＇E and 28°00＇-30°40′ N. The ancient desert study is so little in China that there has not been a systematic report about it up to now. Based on the study in many ways on Cretaceous-Tertiary deserts in southwestern China, plentiful data have been obtained. Though it is still a bit rough, the study is a good beginning of the ancient desert study in China. The main ideas and conclusions are summarized as follows.

A STEADY MODEL ON UPWELING IN A STRAIT

Hsueh and O Brien (1971) proposed a model on coastal upwelling induced by alongshore current. Their model is two - dimensional .steady , f - plane , linear and homogeneous with constant depth , in which wind effect was not considered . In the present paper, we proposed a steady model on upwelling in a strait with alongshore boundary current and wind applied on the surface. The following conclusions have been drawn.1 . Alongshore boundary current contributes more to upwelling than wind near the right coast.2. Alongshore boundary current influence can reach to about 70 km away from the right coast.3. Upwelling in the left half of the strait is mainly produced by wind .4. Under certain conditions, the combined action of wind and alongshore boundary current can produce upwelling in the middle of the strait.

Machine learning algorithms for suicide risk:a premature arms race?

INTRODUCTION Machine learning(ML)techniques1 are becoming a major area of study in psychiatry,as ML possesses the theoretical capacity to draw conclusions based on a broad range of data once the system has been taught through a process of trial and error.Specifically,and arguably most importantly,ML can do so more quickly and accurately than clinicians.2 Several studies have demonstrated accuracy through the use of ML in various populations and geographic locations,further perpetuating the perceived need to incorporate ML into ongoing studies.
