Online chicken carcass volume estimation using depth imaging and 3-D reconstruction.

Variability in the size of slaughtered chickens remains a longstanding challenge in the standardization of the poultry industry. To address this issue, we present a novel approach that uses volume as a grading metric for chicken carcasses. This innovative method, unexplored in existing studies, employs real-time data capture of moving chicken carcasses on a production line using Kinect v2 depth imaging and 3-D reconstruction technologies. The captured depth images are processed into point clouds followed by 3-D reconstruction. Volume is calculated from the reconstructed models using the surface integration method, and additional 2-D and 3-D features are extracted as input parameters for machine learning models. Multiple regression models were evaluated, with the bagged tree model demonstrating superior performance, achieving an R² value of 0.9988, RMSE of 5.335, and ARE of 2.125%. Furthermore, our method showed remarkable efficiency with an average processing time of less than 1.6 seconds per carcass. These results indicate that our novel approach fills a critical gap in existing automated grading methodologies by offering both accuracy and efficiency. This validates the applicability of depth imaging, 3-D reconstruction, and machine learning for estimating chicken carcass volume with high precision, thereby enabling a more comprehensive, efficient, and reliable chicken carcass grading system.

Review of the role of pyroptosis in benign prostatic hyperplasia in old males / 上海交通大学学报（医学版）

Pyroptosis,a new mode of programmed cell death,is primarily characterized by persistent cellular swelling that culminates in cell rupture.This process results in the release of large amounts of inflammatory factors,subsequently triggering an inflammatory response.Benign prostatic hyperplasia(BPH)is the most frequent urological disease in old males and is closely associated with changes in hormones and inflammation response.In recent years,the role of pyroptosis in the occurrence and development of BPH has also received increasing attention.This article summarizes the mechanisms of pyroptosis,concludes the pathogenesis associated with BPH in old males,and outlines the role of pyroptosis in BPH,to provide new ideas for finding more effective therapeutic measures for BPH through pyroptosis.

Role and Significance of Bioactive Substances in Sputum in the Diagnosis of Lung Cancer / 中国肺癌杂志

The incidence rate of lung cancer is one of the highest incidence of malignancies in China. The gold standard for diagnosis requires pathological examination or cytological examination of biopsy. The invasive and sensitive nature of the two limits their use. Sputum contains a large number of nucleic acids and proteins, which is a good reflection of lung function. Lung cancer tissue will also affect the biological components in sputum. The detection of bioactive substances in sputum can contribute to the diagnosis of lung cancer. Based on the current research results at home and abroad, this paper reviews the bioactive substances in sputum that can be used for the diagnosis of lung cancer.

Correlation between serum miR-320b and carotid atherosclerosis in patients with acute ischemic stroke / 国际脑血管病杂志

Objective To investigate the correlation between serum miR-320b and carotid atherosclerosis in patients with acute ischemic stroke.Methods From January 2017 to December 2017,patients with acute ischemic stroke visited the Department of Neurology,the Affiliated Hospital of Yangzhou University were enrolled.According to the findings of carotid artery ultrasonography,they were divided into plaque group and plaque-free group.The baseline clinical data such as demographic data,vascular risk factors,and blood biochemical indicators were collected.Reverse transcription quantitative polymerase chain reaction was used to detect the expression level of serum miR-320b.Multivariatelogistic regression analysis was used to determine the independent risk factors for carotid atherosclerosis.Results A total of 135 patients with acute ischemic stroke were enrolled in this study,including 58 females and 77 males,aged 58.4 ± 10.6 years.There were 85 patients in the plaque group and 50 in the plaque-free group.The total cholesterol (t =5.523,P =0.023) and low-density lipoprotein cholesterol (t =4.415,P =0.044) in the plaque group were significantly higher than those in the plaque-free group,while high-density lipoprotein cholesterol (t =5.849,P=0.017) and serum miR-320b (t =4.331,P=0.039) were significantly lower than those in the plaque-free group.Multivariate logistic regression analysis showed that referring to the highest quartile group,the low serum miR-320b level might be an independent risk factor for carotid atherosclerosis (the first quartile group:odds ratio 2.701,95％ confidence interval 1.154-6.321,P =0.022;the second quartile group:odds ratio 2.521,95％ confidence interval 1.249-5.091,P =0.010;and the third quartile group:odds ratio 1.849,95％ confidence interval 1.041-3.283,P=0.036).Conclusion The low serum miR-320b level might be an independent risk factor for carotid atherosclerosis in patients with acute ischemic stroke.

Dynamic changes of ATP binding cassette transporter A1 expression in perihematomal tissue of mouse cerebral hemorrhage model induced by collagenase / 国际脑血管病杂志

Objective To investigate the ATP binding cassette transporter A1 (ABCA1) expression in perihematomal tissue of mouse cerebral hemorrhage model induced by collagenase. Methods Stereotactic injection of type Ⅳ collagenase was used to induce a model of caudate putamen intracerebral hemorrhage in mice. The behavioral scores were use to assess neurological deficits at 24 h, 48 h and 72 h after model making. Neisserian staining was used to detect the morphology of neurons around hematomas.Immunohistochemical staining and Western blot analysis were used to detect the expression of ABCA1 around hematomas. Results Nissl bodies reduction, atrophy, necrosis of perihematomal neurons were observed and aggravated over time. Immunohistochemical staining and Western blot analysis showed that the expression level of ABCA1 in the perihematomal tissue was significantly higher than that in the sham operation group (all P < 0. 05), and the expression level increased significantly with time (all P < 0. 05 ).Conclusion ABCA1 was up-regulated after cerebral hemorrhage, suggesting that it might be involved in the pathological process of cerebral hemorrhage.
