Human body contains diverse microbes. Different microbes are identified at different organs. Urine was thought as sterile, but according to progression in important technologies like 16S rRNA gene sequencing and expanded quantitative urine culture, it is known that diverse microbes exist in genitourinary tract. Microbiome contains the microbes and surrounding microenvironments. In addition to urologic difficulties like interstitial cystitis or chronic prostatitis, malignancies are thought to be related to microbiomes. In this review, we summarized several studies in urologic malignancies, especially prostate cancer and kidney cancer.

5.Role of the Epithelial-Mesenchymal Transition in Bladder Cancer: From Prognosis to Therapeutic Target.
Korean Journal of Urology 2013;54(10):645-650
Bladder cancer (BC) is the second most common malignancy of urological organs. However, patients with non-muscle-invasive BC are at high risk of recurrence and progression into muscle-invasive BC, and the prognosis of patients with muscle-invasive BC is limited by the high rate of metastasis. The epithelial-mesenchymal transition (EMT) is characterized by loss of cell-to-cell adhesion and cell polarity and is closely associated with the invasion and metastasis of several cancers. Given the multifocality and high rates of relapse, progression, and metastasis of BC, the EMT is likely to participate in BC as well. Numerous factors associate with the EMT, and the key regulators of the EMT are E-cadherin, N-cadherin, Twist, Snail, Slug, Zeb-1, Zeb-2, vimentin, and microRNAs. This review focuses on the current concepts regarding the EMT in cancer and the evidence for involvement of the EMT in BC. Several potential EMT targets that may be useful in the treatment of BC are also described.

The purpose of this study is to provide a fundamental basis for defining measures to prevent suicide by specifically examining the relationship between suicide and alcohol consumption, which is thought to be a key factor in suicide. This study reviewed 426 suicide autopsies diagnosed by the department of forensic medicine, National Forensic Service (2007-2009) and analyzed the preliminary data on variables such as gender, age, and cause of death, with particular focus on the relationship between these variables and blood alcohol concentration. The relationship between each variable and alcohol consumption was as follows. First, alcohol was present in 48.4% of suicides. Second, blood alcohol concentration wrere twice as high in women as in men. Third, the relationship between suicide and alcohol consumption was greater in people in their 30s and 40s. The correlation between suicide and alcohol intake was evident this age group. These results are more specific and practical than the results of previous studies on the correlation between suicide and alcohol intake. The results of this study will help define measures to facilitate suicide prevention as an important reference and may eventually help lower the suicide rate in Korea.

PURPOSE: Forkhead transcription factor FKHR (FOXO1) is one member of the Forkhead transcription factor family, and it is thought to regulate the glucose metabolism in human and to be related to both cell cycle progression and cell apoptosis. Herein, we investigated the expression level of FOXO1 and its clinical implications in bladder cancer. MATERIALS AND METHODS: From June 1992 to June 2005, 145 specimens were harvested from primary bladder cancer and 102 specimens were harvested from normal-looking tissue surrounding the tumor mass; these specimens were investigated for determining the mRNA expression levels of FOXO1 with using the real-time PCR method. The expression levels of FOXO1 were compared statistically with such clinical variables as stage, grade, recurrence and progression. Survival analysis was performed using the Kaplan-Meier model. RESULTS: The expression levels of FOXO1 in the bladder cancer specimens (28.19pg/ml) were significantly higher than those of the corresponding normal bladder tissues (8.87pg/ml) that surrounded the tumor mass (p<0.001), and the expression levels of FOXO1 were significantly correlated with stage and the progression of superficial disease (p<0.05 each). Also, the expressions of FOXO1 of the patients who remained alive during the study period were higher than those of the nonsurviving patients (p<0.001). A higher expression of FOXO1 in the patients with superficial bladder tumor showed more survival benefit than a lower expression (p=0.004). But the recurrence and differentiation of bladder cancer were not correlated with the expression level of FOXO1. CONCLUSIONS: This data indicate that the expression level of FOXO1 can be recommended as a useful marker to predict disease occurrence as well as the progression and survival of patients with superficial bladder cancer.

The fine structure of cells in the trigeminal mesencephalic (Me5) nucleus in the rat was studied by transmission electron microscopy. This nucleus located in the mid-brain and the rostral portion of the pons, most neurons in the caudal part of Me5 nucleus were sufficiently large (40~50micrometer) and appeared as round-shaped unipolar cells. The Me5 neurons had a large, round, centrally located nucleus, and their cytoplasm contained numerous mitochondria, dense granular endoplasmic reticulum, abundant Golgi apparatus, groups of free ribosomes, some heterogeneous particles and neurofilaments. Cell surfaces were studded irregularly with small spinouts processes, and they contained a few fine irregularly arranged neurofilaments and some granular endoplasmic reticulum. Boutons contacting the soma of Me5 neurons were defined as axosomatic synapses and bostons contacting dendrites located between the Me5 neurons were defined as axodendritic synapses. Based on differences in bouton and vesicle morphology, the four synaptic bouton types were identified. 1. Asymmetrical as well as symmetrical synapses with small round vesicles. 2. Asymmetrical synapses with pleomorphic admixture contained predominantlyspherical vesicles. 3. Symmetrical synapses with pleomorphic vesicles of flattened, spherical and dense-core vesicles. 4. Asymmetrical as well as symmetrical synapses with heterogeneous and large dense-core vesicles. Synaptic boutons containing round vesicles and large dense-core vesicles were most frequently observed.

PURPOSE: Urolithiasis develops more frequently in patients with a family history (FHx). However, little is known about risk factors in stone formers with a FHx. The aim of this study was to examine the clinico-metabolic characteristics of urinary stone formers according to FHx. MATERIALS AND METHODS: A database of 1,068 stone formers who underwent a complete metabolic evaluation was reviewed. The patients were divided into two groups on the basis of the presence of a FHx. Clinical factors and metabolic parameters were compared between the two groups. RESULTS: There were no significant differences in clinical characteristics, such as gender, age, body mass index, stone episodes, or multiple stones, between the two groups (p>0.05, respectively). Compared with stone formers without a FHx, however, serum calcium concentrations were more elevated in stone formers with a FHx. Also, the urinary excretion of calcium was higher in stone formers with a FHx than in those without a FHx. Other urinary metabolites showed no significant differences between the two groups (p>0.05, respectively). CONCLUSIONS: Our study revealed that stone formers with a FHx had increased urinary calcium excretion as well as elevated concentrations of serum calcium. This finding suggests that urolithiasis in stone formers with a FHx may be associated with calcium metabolic abnormalities.
