The value of predicting the invasiveness and degree of infiltration of pulmonary ground-glass nodules based on computed tomography features and enhanced quantitative analysis.

Background: The incidence and mortality rate of lung cancer are the highest in the world among all malignant tumors. Accurate assessment of ground-glass nodules (GGNs) is crucial in reducing lung cancer mortality. This study aimed to explore the value of computed tomography (CT) features and quantitative parameters in predicting the invasiveness and degree of infiltration of GGNs.

Deep learning models for separate segmentations of intracerebral and intraventricular hemorrhage on head CT and segmentation quality assessment.

Background: The volume measurement of intracerebral hemorrhage (ICH) and intraventricular hemorrhage (IVH) provides critical information for precise treatment of patients with spontaneous ICH but remains a big challenge, especially for IVH segmentation. However, the previously proposed ICH and IVH segmentation tools lack external validation and segmentation quality assessment.

Purpose: This study aimed to develop a robust deep learning model for the segmentation of ICH and IVH with external validation, and to provide quality assessment for IVH segmentation.

Effects of Six Natural Compounds and Their Derivatives on the Control of Coccidiosis in Chickens.

Chicken coccidiosis costs the poultry industry over GBP 10 billion per year. The main method of preventing and controlling coccidiosis in chickens continues to be the use of drugs. Unfortunately, the prevalence of drug resistance in the field reduces or even eliminates the effectiveness of drugs, and drug residues in the food supply chain can also can be harmful to humans.

Computerized Tomography (CT) Updates and Challenges in Diagnosis of Bone Metastases During Prostate Cancer.

Prostate cancer is one of the most common cancers in men. This cancer is often associated with indolent tumors with little or no lethal potential. Some of the patients with aggressive prostate cancer have increased morbidity and early deaths.

Clinical and Dynamic Computed Tomography Features of 24 Patients With Coronavirus Disease 2019.

Purpose: To explore the clinical and dynamic computed tomography features of coronavirus disease 2019.

Methods: We enrolled 24 patients with coronavirus disease 2019 treated at a regional center in Dezhou, China, from January 22 to February 5, 2020, and analyzed data retrospectively.

Results: Nineteen cases had close contact with people with coronavirus disease 2019, and five patients denied a travel history in Wuhan City or contact with patients having coronavirus disease 2019.

MRI Combined with Magnetic Resonance Cholangiopancreatography for Diagnosis of Benign and Malignant Pancreatic Intraductal Papillary Mucinous Neoplasms.

Background: Intraductal papillary mucinous neoplasms (IPMNs) are among the important premalignant lesions. Early detection and intervention are critical to positive patient outcomes. Magnetic resonance imaging (MRI) can be used to evaluate the malignancy of IPMNs, and magnetic resonance cholangiopancreatography (MRCP) is recommended for follow-up of pancreatic cystic lesions.

Population ecology of rhesus monkeys (Macaca mulatta) at Nanwan Nature Reserve, Hainan, China.

Rhesus monkeys (Macaca mulatta) at the Nanwan peninsula of Hainan Island, China, have been observed in the field for 25 years, and have been studied intensively for eight years, beginning in 1981. There were about 115 monkeys in 5 natural groups when the Nanwan Reserve was founded in 1965. From 1965 to 1984, the number of groups increased from 5 to 19, and the total population increased from 115 to 930 individuals, an annual population increase of 12.

Population structure of Hylobates concolor in Bawanglin Nature Reserve, Hainan, China.

The Hainan gibbon continues to survive in Bawanglin Nature Reserve in four social groups totalling 21 individuals. Twelve births have occurred since 1982, and 11 of these individuals survive in 1989. Only three of these 12 births have been females, however.
