Diaphragmatic pheochromocytoma: Two case reports and a review of the literature.

Rationale: Pheochromocytomas typically arise in the adrenal medulla, whereas ectopic pheochromocytomas/paragangliomas commonly occur near the abdominal aorta, bladder, mediastinum, and head. Diaphragmatic pheochromocytomas are exceedingly rare, and there is limited surgical experience with their treatment.

Patient Concerns: In Case A, the subject is a 45-year-old male, while in Case B, the subject is a 59-year-old female.

Renal myopericytoma: A case report with a literature review.

Myopericytoma is a rare soft tissue tumor characterized by differentiation into perivascular muscle-like cells or perimuscular cells. This tumor primarily affects adults and is uncommon in children. It is predominantly found in the subcutaneous soft tissues of the distal limbs, and cases originating in the kidney are exceedingly rare.

Effects of Ginsenoside Rg1 on the Biological Activity of Human Periodontal Ligament Cells.

Stabilization of microtubules improves cognitive functions and axonal transport of mitochondria in Alzheimer's disease model mice.

One major pathological process in Alzheimer's disease is mediated by hyperphosphorylated tau, which includes altered microtubules (MTs) and functions associated with tau. A potential way to compensate for altered MT function is to use an MT stabilizer, such as epothilone D (EpoD). Previous studies have demonstrated improved cognitive functions and axonal transport by EpoD in tau-mutation mice.

Chinese Herbal Medicine Xueshuantong Enhances Cerebral Blood Flow and Improves Neural Functions in Alzheimer's Disease Mice.

Reduced cerebral blood flow in Alzheimer's disease (AD) may occur in early AD, which contributes to the pathogenesis and/or pathological progression of AD. Reversing this deficit may have therapeutic potential. Certain traditional Chinese herbal medicines (e.

Interaction network analysis of differentially expressed genes and screening of cancer marker in the urine of patients with invasive bladder cancer.

Objective: To detect the expression profile of bladder cancer and to delineate the interaction network of these genes in invasive bladder cancer.

Methods: A total of 126 differentially expressed genes were identified, and input into STRING online database to delineate interaction network. The network data were screened with central nodes.

Screening and identification of specific markers for bladder transitional cell carcinoma from urine urothelial cells with suppressive subtractive hybridization and cDNA microarray.

Objective: The objective of this study was to screen and identify differentially expressed genes in invasive bladder transitional cell carcinoma (BTCC).

Methods: Voided urine samples were collected from consecutive patients with BTCC and patients under surveillance for bladder cancer recurrence; voided urine samples from patients with non-malignant diseases served as control. We identified the differentially expressed genes by comparing urine samples of bladder carcinoma to that of the control group with suppressive subtractive hybridization (SSH) and cDNA microarray.

[Tumor necrosis factor alpha-308 polymorphism and asthenospermia].

Objective: To investigate the relationship between -308 genotype polymorphism in the promoter region of the tumor necrosis factor alpha (TNFalpha) gene and asthenospermia in infertile men.

Methods: Allele-specific polymerase chain reaction (ASPCR) and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) were used to analyze the genotype at position -308 in the promoter region of the TNFalpha gene in 187 infertile male patients, who were divided into Groups A (asthenospermia, n = 60), B (oligoasthenozoospermia, n = 65) and C (infertile patients with normal sperm, n = 62). The levels of TNFalpha in the seminal plasma from these patients were measured by radioimmunoassay, and all the data were statistically analyzed by SPSS16.
