An experiment is conducted to investigate the effects of selenium (Se) source and level on growth performance, tissue Se concentrations, antioxidation, and immune functions of heat-stressed broilers from 22 to 42 days of age. A total of 210 22-day-old Arbor Acres commercial male chicks were assigned by body weight to one of seven treatments with six(More)
MicroRNAs (miRNAs) are small non-coding RNAs that participate in the spatiotemporal regulation of messenger RNA (mRNA) and protein synthesis. Recent studies have shown that some miRNAs are involved in the progression of nasopharyngeal carcinoma (NPC). However, the aberrant miRNAs implicated in different clinical stages of NPC remain unknown and their(More)
An experiment was conducted to investigate the bioavailability of organic manganese proteinate (Mn) relative to inorganic Mn sulfate for broilers fed a conventional corn–soybean meal basal diet. A total of 448-day-old Arbor Acres commercial male chicks were fed the Mn-unsupplemented basal diet (control) or basal diet supplemented with 60, 120, or 180 mg(More)
miR-124 and miR-506 are reportedly down-regulated and associated with tumor progression in many cancers, but little is known about their intrinsic regulatory mechanisms in colorectal cancer (CRC). In this study, we found that the miR-124 and miR-506 levels were significantly lower in human CRC tissues than in controls, as indicated by qRT-PCR and in situ(More)
Two experiments were conducted to investigate the kinetics of manganese (Mn) transport in Caco-2 cell monolayers and the gene expressions of Mn transport carriers in apical (AP) and basolateral (BL) membranes. In experiment 1, the cells were treated with the medium containing 146 μmol/L of Mn (MnSO4·H2O). Both the uptake and transport of Mn from AP–BL or(More)
An experiment was conducted to investigate the bioavailability of organic copper (Cu) proteinate relative to inorganic Cu sulfate for broiler chicks fed a conventional corn–soybean meal basal diet. A total of 320 day-old Arbor Acres commercial male chicks were assigned to one of five treatments in a completely randomized design involving a 2 × 2 factorial(More)
Bone marrow-derived mesenchymal stem cells (BMSCs, also known as bone marrow-derived mesenchymal stromal cells) are known to be a component of the tumor microenvironment. BMSCs are multipotent stromal cells that can differentiate into a variety of cell types, including osteocytes, chondrocytes, adipocytes, epithelial cells and endothelial cells. Stem cells(More)
Paragangliomas are neoplasms that arise from extra-adrenal chromaffin cells. Pancreatic paragangliomas are rare, and few are malignant. To the best of our knowledge, no cases of functional pancreatic paragangliomas have been reported in the literature to date. We present two cases of pancreatic paragangliomas with pathological confirmation. In the case 1,(More)
BACKGROUND Central lymph node metastasis of papillary thyroid microcarcinoma (PTMC) is common; however, prophylactic central lymph node dissection (CLND) is still controversial because of the possible increased morbidity. The purpose of this study is to determine the clinical outcome of patients with cN0 PTMC by central neck dissection. METHODS A(More)
The objective of this study was to develop a procedure for estimating the standardized mineral (calcium, Ca; phosphorus, P; copper, Cu; manganese, Mn; zinc, Zn) availabilities (SMA) in soybean meal for broilers. In experiment 1, twelve 24-day-old male chicks were used to determine the length of the pre-experimental fasting period needed to empty the total(More)
