RESUMO
A clinical case of a penile fracture as a result of an unsuccessful sexual intercourse, which later required surgical treatment in the form of corporoplasty with opening and draining of the hematoma, is discussed in the article. Penile fracture is a rare urological emergency that requires immediate medical attention to avoid long-term complications, including penile curvature and erectile dysfunction.

The natural occurrence of arsenic (As) in groundwater & soils and its bioaccumulation in rice grains is a major health concern worldwide. To combat the problem, best combination of irrigation management and suitable rice variety altering As content in grains must be ensured. With this aim, a field trial was conducted with two rice varieties and water management including alternate wetting and drying (AWD) and continuous flooding (CF) irrigation regimes with As contaminated groundwater (AsW) and temporarily stored groundwater (TSG) and river water for only CF (as control). Results revealed that As content in different portions of paddy plant was significantly different (P < 0.001) with irrigation practices and rice varieties. AWD irrigation with TSG accumulated lower As in rice grains compared with CF-AsW for both varieties. Data showed that AWD-TSG practice led to 61.37% and 60.34% grain As reduction for BRRI dhan28 and BRRI dhan29, respectively, compared with CF-AsW. For Principle Component Analysis (PCA), first principle component (PC1) explained 91.7% of the variability and irrigation water As, soil total and available As, straw As, root As and husk As were the dominating parameters. With significant (P < 0.05) variation in yields between the genotypes, AWD increased grain yield by 29.25% in BRRI dhan29 Compared with CF. However, translocation factor (TF) and bioconcentration factor (BCF) for both varieties were less than one for all the treatments. The addition of this study to our knowledge base is that, AWD-TSG with BRRI dhan29 can be an As-safe practice without compromising yields.

OBJECTIVE: This study aimed to explore the expression and clinical significance of LINC01197 in serum of patients with pancreatic cancer (PC). PATIENTS AND METHODS: Fifty PC patients (patient group) treated in our hospital from March 2012 to April 2014 were collected, and another 50 normal people (normal group) were collected for physical examination. The LINC01197 expression in serum of the two groups was detected by qRT-PCR method, and the CA 19.9 expression in serum was detected by Roche automatic biochemistry. The expression and diagnostic value of CA 19.9 and LINC01197 in PC were analyzed, and the relationship between LINC01197 and prognosis of PC patients was observed. RESULTS: The CA 19.9 expression in the patient group was significantly higher than that in the normal group (p<0.001). Their area under the curve was 0.791 and 0.944 respectively. The incidence of phases III+IV, lymphatic invasion, and distant metastasis in patients with low expression of LINC01197 is significantly higher than that in those with high expression, and has higher diagnostic value. With the progress of clinical staging, the TNM expression decreased gradually and there were differences between groups (p<0.001). Spearman's test analysis found that the decreased TNM staging of LINC01197 increased gradually (r=-0.816, p<0.001), and the area under the curve of LINC01197 distinguishing phase I and phase II+phase+III+phase IV was 0.930. The 1-year survival rate and 5-year survival rate of patients in low expression group were lower than those in high expression group (p1 year =0.037, p5 year =0.014). Distant metastasis is an independent prognostic factor for PC patients to survive for 1 to 5 years. Differentiation, TNM staging, and LINC01197 are independent prognostic factors for PC patients to survive for 5 years. CONCLUSIONS: The low expression of LINC01197 in PC patients indicates poor prognosis of patients and is expected to be a potential diagnostic and prognostic indicator of PC.

The electrochemical behavior of thallium was studied on glassy carbon electrodes in sulfate solutions. Cyclic voltammetry was used to study the kinetics of the electrode processes and to determine the nature of the limiting step of the cathodic reduction of thallium ions. According to the dependence of current on stirring rate and scan rate, this process is diffusion limited. Chronocoulometry showed that the electrodeposition can be performed with a current efficiency of up to 96% in the absence of oxygen.
