Machine learning for temporary stoma after intestinal resection in surgical decision-making of Crohn's disease.

Background: Crohn's disease (CD) often necessitates surgical intervention, with temporary stoma creation after intestinal resection (IR) being a crucial decision. This study aimed to construct novel models based on machine learning (ML) to predict temporary stoma formation after IR for CD.

Methods: Patient data who underwent IR for CD at our center between July 2017 and March 2023 were collected for inclusion in this retrospective study.

Carbon and nitrogen stoichiometry across plant-soil system accounts for the degradation of multi-year alfalfa grassland.

Alfalfa ( L.) grassland is prone to degradation following multi-year maintenance. Yet, its mechanism regarding the stoichiometry of carbon (C) and nitrogen (N) across plant-soil system is still unclear.

The role of the CXCR6/CXCL16 axis in the pathogenesis of fibrotic disease.

CXC chemokine receptor 6 (CXCR6), a seven-transmembrane domain G-protein-coupled receptor, plays a pivotal regulatory role in inflammation and tissue damage through its interaction with CXC chemokine ligand 16 (CXCL16). This axis is implicated in the pathogenesis of various fibrotic diseases and correlates with clinical parameters that indicate disease severity, activity, and prognosis in organ fibrosis, including afflictions of the liver, kidney, lung, cardiovascular system, skin, and intestines. Soluble CXCL16 (sCXCL16) serves as a chemokine, facilitating the migration and recruitment of CXCR6-expressing cells, while membrane-bound CXCL16 (mCXCL16) functions as a transmembrane protein with adhesion properties, facilitating intercellular interactions by binding to CXCR6.

Novel insight into anthocyanin metabolism and molecular characterization of its key regulators in Camellia sasanqua.

Flower color is a trait that affects the ornamental value of a plant. Camellia sasanqua is a horticultural plant with rich flower color, but little is known about the regulatory mechanism of color diversity in this plant. Here, the anthocyanin profile of 20 C.

Ancient DNA from Tubo Kingdom-related tombs in northeastern Tibetan Plateau revealed their genetic affinity to both Tibeto-Burman and Altaic populations.

The rise of the Tubo Kingdom is considered as the key period for the formation of modern groups on the Tibetan Plateau. The ethnic origin of the residents of the Tubo Kingdom is quite complex, and their genetic structure remains unclear. The tombs of the Tubo Kingdom period in Dulan County, Qinghai Province, dating back to the seventh century, are considered to be the remains left by Tubo conquerors or the Tuyuhun people dominated by the Tubo Kingdom.

The complete chloroplast genome of Craib 1914, an economically valuable oil crop.

Craib 1914 is an industrially valuable oil crop from southern China for which little genetic information is available. Here, we found that its complete chloroplast genome is a circular sequence (156,905 bp) with a large single-copy region (LSC) of 67,724 bp, a small single copy region (SSC) of 18,400 bp, and two inverted repeats (IRs). In total, 130 genes were identified, including 86 protein-coding genes, 36 transfer RNAs, and 8 rRNA genes.

[The effect of transcranial direct current stimulation on dysfunction of bilateral posterior cingulate cortex after sleep deprivation: a preliminary study].

To investigate the effects of transcranial direct current stimulation (tDCS) on the disturbance of brain network dysfunction after sleep deprivation (SD). The experimental design of self-control was used in the study. All 16 subjects received 2 times of 24 h SD with an interval of 3 weeks.

Postoperative Cognitive Dysfunction Induced by Different Surgical Methods and Its Risk Factors.

The aim of the present study was to compare the effect of different surgical methods on postoperative cognitive function in patients undergoing abdominal surgery, determine the risk factors of postoperative cognitive dysfunction (POCD) by logistic regression, and investigate these risk factors through different surgical methods. A total of 70 patients undergoing selective abdominal surgery were selected into this study. The age of these patients ranged within 32 to 85 years.

[Spectroscopic Study on a Direct-Current Driving Plasma Jet in Argon at Atmospheric Pressure].

With a discharge device in a hollow-needle and plate electrode configurations, an atmospheric pressure uniform plasma plume is generated by DC voltage excitation in the ambient air with argon as working gas. The plasma plume is a pulsed discharge despite a direct current voltage is applied through measurements by optical and electrical methods. In order to explain the formation mechanism of the pulse, spatially resolved signals emitted from the plume were detected.

[Investigation on the Spectral Characteristics of a Plasma Jet in Atmospheric Argon Glow Discharge].

Plasma jet is a kind of important plasma source at atmospheric pressure. In recent years, it becomes an important hot topic in the field of low temperature plasma. In this paper, using a tungsten needle and a tungsten wire mesh, a direct-current excited jet is developed to operate in argon at atmospheric pressure.

Overexpression of long non-coding RNA UCA1 predicts a poor prognosis in patients with esophageal squamous cell carcinoma.

Introduction: Long non-coding RNAs (lncRNAs) have been shown to have important regulatory roles in cancer biology, and the lncRNA UCA1 is upregulated in several cancers such as bladder cancer, breast cancer and colorectal cancer, however, the contributions of UCA1 to esophageal cancer remain largely unknown.

Methods: Expression levels of lncRNA UCA1 in esophageal squamous cell carcinoma (ESCC) patients and esophageal cancer cell lines were evaluated by quantitative real-time PCR (qRT-PCR), and its association with overall survival of patients was analyzed by statistical analysis. Small interfering RNA was used to suppress UCA1 expression in esophageal cancer cell line.

[Population structure and spatial distribution pattern of Camellia azalea in E' huangzhang Nature Reserve of Guangdong, China].

This paper studied the structures of basal diameter, height and canopy width of Camellia azalea population in E' huangzhang Nature Reserve of Guangdong. The spatial distribution patterns and dynamics of the population were measured by applying aggregate indices including disperse coefficient, negative binomial distribution, Cassie index, clumping index, mean crowding, patch index and Green index. The results showed that in the natural distribution region, the population was mainly composed of adult trees, and was in declining due to seriously lack of seedlings.

Functional analyses of a flavonol synthase-like gene from Camellia nitidissima reveal its roles in flavonoid metabolism during floral pigmentation.

The flavonoids metabolic pathway plays central roles in floral coloration, in which anthocyanins and flavonols are derived from common precursors, dihydroflavonols. Flavonol synthase (FLS) catalyses dihydroflavonols into flavonols, which presents a key branch of anthocyanins biosynthesis. The yellow flower of Camellia nitidissima Chi.

Ultradian rhythms and the nutritional importance of caecotrophy in captive Brandt's voles (Lasiopodomys brandtii).

Ingestion of soft faeces derived from caecal contents, caecotrophy, in herbivorous small mammals is considered an adaptation to the metabolic disadvantage of small body size, especially when feeding on diets of low quality. We investigated daily activity patterns in captive Brandt's voles (Lasiopodomys brandtii), including feeding, locomotion, caecotrophy, and defaecation, by continuous 24 h visual observation; and estimated the contribution of soft faeces ingestion (caecotrophy) to intake of protein and energy. Brandt's voles ingested 68.
