Uric acid metabolism was investigated in 27 overweight subjects, 11 men (176 +/- 30 percent of ideal body weight) and 16 women (169 +/- 20 percent of ideal body weight). They were all hospitalized and treated with low-calorie diets (1,500-800 kcal/day) with gradual reduction of total calorie intake; exercise therapy (walking, and riding a bicycle ergometer) was added to this regimen afterwards. On admission, serum levels of uric acid were significantly elevated to 9.2 +/- 1.9 mg/dl in males (con

Early studies suggested androgen receptor (AR) splice variants might contribute to the progression of prostate cancer (PCa) into castration resistance. However, the therapeutic strategy to target these AR splice variants still remains unresolved. Through tissue survey of tumors from the same patients before and after castration resistance, we found that the expression of AR3, a major AR splice variant that lacks the AR ligand-binding domain, was substantially increased after castration resistanc

M-PLA2 is closely related to the malignant potential of breast cancers, and the M-PLA2 contents in breast cancer tissues could be a new valuable prognostic factor, other than the hormone receptor, in delineating the status of human breast cancer.

Our study demonstrated that thoracoscopic segmentectomy was feasible with regard to peri-operative and oncological outcomes for Stage IA NSCLC, especially T1a and carefully selected T1b descriptor.

Survivin is an indicator of the recurrence of early-stage breast cancer. Survivin might be used as a new marker to stratify early-stage breast cancer patients for more optimal treatment modalities, or it could be a promising target for therapy.

The morphological subtyping of PRCC is significantly associated with clinicopathological features and the prognosis. Our results provide evidence of the clinical utility of dividing PRCC into two subtypes.

Most intravesical recurrences occur around the site of bladder mucosal injury within 1 year after radical nephroureterectomy, providing important insight into the mechanism of intravesical recurrence. Intravesical recurrence after radical nephroureterectomy had an impact on oncological outcomes of patients with non-muscle invasive upper urinary tract urothelial carcinoma.

Patients with high DYRK2 expression could be good candidates for chemotherapy.

Ki-67 LI after VATS segmentectomy was a prognostic factor of disease-free survival in NSCLC and the treatment of choice for patients with positive LI may be considered, in addition to adjuvant chemotherapy, or lobectomy.

Expression levels of IL-6 in the MPG were increased in the acute phase following CN injury. Inhibition of IL-6 bioactivity attenuated ED following CN dissection. Thus, the suppression of excess inflammatory responses in the acute phase may lead to improvements in ED occurring after nerve-sparing radical prostatectomy.

Testicular cancer occurs in the testes of the male reproductive system and is the most common cancer in adolescent and young adult (AYA) men. However, recently, there have been more cases of testicular cancer in men older than 40 years. Therefore, trends of testicular cancer during the past 40 years were retrospectively examined, focusing on age and histology. Patients who were diagnosed with testicular cancer at our institution between 1980 and 2019 were enrolled in this study. The patients wer
