Polysaccharide immunization and colorectal cancer: A systematic review and network meta-analysis
Polysaccharides have a variety of biological activities, and in the anti-tumor field, they produce tumor suppressive effects by regulating the polarization of tumor-associated macrophages (TAMs). In immunotherapy, it has significant activities in modulating cytokines and antibody production. We reviewed them and selected CD24, an immune target, for meta-analysis with colorectal cancer (CRC) to investigate the correlation between CD24 expression and CRC. Correlation of CD24 positive expression with clinical-pathological features: age, sex, Duke’s stage, diameter, depth of invasion, degree of differentiation, and lymph node metastasis. It showed that: CD24 expression in CRC was significantly correlated with advanced nuclear grade of CRC, lymph node metastasis, Duke’s stage of CRC and age of CRC patients, while there was no significant correlation with gender, tumor diameter and invasion depth. The aim is to clarify the specific mechanism of polysaccharide immune anti-tumor, combined with targeted site-specific anti-solid tumor
BASIC STUDY FOR COAL MOISTURE CONTROL INTEGRATING PNEUMATIC CLASSIFICATION TECHNIQUE
A technique of coal moisture control integrating pneumatic classification with flue gas as heating medium was put forward. With this technique, refined coal moisture control can be realized accompanying classification in one process, and considerable high-quality energy can be saved in coking and milling procedure. In this paper, coal classification and moisture control behaviors was investigated at different conditions. Based on experimental results, the basic parameters for the technique were worked out accordingly
Studi Pengetahuan Tentang Menstruasi Dengan Upaya Penanganan Dismenore Pada Mahasiswa Pendidikan Biologi
. Dysmenorrhea is a condition of pain during menstruation experienced by women. There are heavy and light of menstruation pain, knowledge of menstruation disorder will determine of the dysmenorrhea holding efforts. The purpose of this study was to determine the relationship of knowledge about menstruation and dysmenorrhea holding efforts. The population of this study was all students of Biology Education 6th semester who are taking the course of Human Anatomy and Physiology, while samples were taken by purposive sampling, with the criteria of female students who experience dysmenorrhea. Data of knowledge about menstruation collected by a multiple choice test, whereas the holding of dysmenorrhea collected using questionnaires. Furthermore, the relationship of knowledge of menstruation and the holding of dysmenorrhea was analyzed by Product Moment. The results showed that the students with good knowledge of menstruation were 72.7%, insufficient knowledge were 27.3% and less knowledge were 0%. Dysmenorrhea treatment efforts are chosen by the students are varied, students who choose to pharmacological and non-pharmacological simultaneously is 2 ( 6.06% ) , non-pharmacological means only 31 people ( 93.94 % ) . Product moment correlation test results obtained rcount = 0.014 < rtable 0.05: 33 = 0.344, meaning there is no relationship between student knowledge about menstruation and preventing dysmenorrhea . The conclusion of this study are : a) the student\u27s knowledge about menstruation mostly categorized as good , b ) The handling of dysmenorrhea by students mostly by way of non-pharmacological; c ). Student knowledge about menstruation does not specify the handling of dysmenorrhe
Structural and Functional Alterations in Visual Pathway After Optic Neuritis in MOG Antibody Disease: A Comparative Study With AQP4 Seropositive NMOSD
Background: Optic neuritis (ON) is an important clinical manifestation of neuromyelitis optic spectrum disease (NMOSD). Myelin oligodendrocyte glycoprotein (MOG) antibody-related and aquaporin 4 (AQP4) antibody-related ON show different disease patterns. The aim of this study was to explore the differences in structure and function of the visual pathway in patients with ON associated with MOG and AQP4 antibodies.Methods: In this prospective study, we recruited 52 subjects at Beijing Tiantan Hospital, including 11 with MOG Ig+ ON (MOG-ON), 13 with AQP4 Ig+ ON (AQP4-ON), and 28 healthy controls (HCs). Fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (AD), and radial diffusivity (RD) of optic radiation (OR), primary visual cortex volume (V1), brain volume, and visual acuity (VA) were compared among groups. A multiple linear regression was used to explore associations between VA and predicted factors. In addition, we used optical coherence tomography (OCT) to examine thickness of the peripapillary retinal nerve fiber layer (pRNFL) and retinal ganglion cell complex (GCC) in a separate cohort consisting of 15 patients with ON (8 MOG-ON and 7 AQP4-ON) and 28 HCs.Results: Diffusion tensor imaging showed that the FA of OR was lower than controls in patients with AQP4-ON (p = 0.001) but not those with MOG-ON (p = 0.329) and was significantly different between the latter two groups (p = 0.005), while V1 was similar in patients with MOG-ON and AQP4-ON (p = 0.122), but was lower than controls in AQP4-ON (p = 0.002) but not those with MOG-ON (p = 0.210). The VA outcomes were better in MOG-ON than AQP4-ON, and linear regression analysis revealed that VA in MOG-ON and AQP4-ON was both predicted by the FA of OR (standard β = −0.467 and −0.521, p = 0.036 and 0.034). Both patients of MOG-ON and AQP4-ON showed neuroaxonal damage in the form of pRNFL and GCC thinning but showed no statistically significant difference (p = 0.556, 0.817).Conclusion: The structural integrity of OR in patients with MOG-ON, which is different from the imaging manifestations of AQP4-ON, may be a reason for the better visual outcomes of patients with MOG-ON
Evaluating the Potential of Leading Large Language Models in Reasoning Biology Questions
Recent advances in Large Language Models (LLMs) have presented new
opportunities for integrating Artificial General Intelligence (AGI) into
biological research and education. This study evaluated the capabilities of
leading LLMs, including GPT-4, GPT-3.5, PaLM2, Claude2, and SenseNova, in
answering conceptual biology questions. The models were tested on a
108-question multiple-choice exam covering biology topics in molecular biology,
biological techniques, metabolic engineering, and synthetic biology. Among the
models, GPT-4 achieved the highest average score of 90 and demonstrated the
greatest consistency across trials with different prompts. The results
indicated GPT-4's proficiency in logical reasoning and its potential to aid
biology research through capabilities like data analysis, hypothesis
generation, and knowledge integration. However, further development and
validation are still required before the promise of LLMs in accelerating
biological discovery can be realized
