Global compilation of benthic data sets I

Approaches to quantify the organic carbon accumulation on a global scale generally do not consider the small-scale variability of sedimentary and oceanographic boundary conditions along continental margins. In this study, we present a new approach to regionalize the total organic carbon (TOC) content in surface sediments (<5 cm sediment depth). It is based on a compilation of more than 5500 single measurements from various sources. Global TOC distribution was determined by the application of a combined qualitative and quantitative-geostatistical method. Overall, 33 benthic TOC-based provinces were defined and used to process the global distribution pattern of the TOC content in surface sediments in a 1°x1° grid resolution. Regional dependencies of data points within each single province are expressed by modeled semi-variograms. Measured and estimated TOC values show good correlation, emphasizing the reasonable applicability of the method. The accumulation of organic carbon in marine surface sediments is a key parameter in the control of mineralization processes and the material exchange between the sediment and the ocean water. Our approach will help to improve global budgets of nutrient and carbon cycles.

Análise comparativa da imunoexpressão do IMP-3 e Ki-67 em queilites actínicas e carcinoma epidermóide de lábio inferior

Epithelial changes observed in actinic cheilitis (AC) and squamous cell carcinoma of the lower lip (LLSCC) are mainly caused by chronic exposure to ultraviolet rays (UV) and are studied using different immunohistochemical markers trying to evaluate the process of carcinogenesis. The objective of this study was to comparatively evaluate the expression of Ki-67 proteins and IMP-3 in AC and LLSCC to contribute with additional information on carcinogenesis in lower lip. A total of 33 cases of AC and 33 cases of LLSCC were studied, analyzed the clinical and pathological features and immunostaining of Ki-67 and IMP-3. Immunohistochemical analysis of Ki-67 was made through the determination of the proliferation index (PI) and subsequent classification of the cases according to the scores: 0 (0% positive cells) +1 (≤30%) + 2 (> 30% and ≤60%) and +3 (> 60%). For statistical tests cases were classified as unmarked (score 0), low expression (score +1) and high expression (scores +2 and +3). For the expression of IMP-3, the percentage of immunostained epithelial cells was established, and assigned scores: 0 (corresponding to 0%), +1 (up to 30% of positive cells); +2 (From 30% to 60% of immunostained cells) and +3 (over 60% of positive cells). Statistical tests chi-square test, Mann-Whitney and Wilcoxon were used. The significance level was 5%. Most AC chaos was male (78.8%) with mean age of 50 years and cases of LLSCC also were male (69.89%) with an average of 62 years. The Ki-67 was expressed in all cases of AC and in cases of LLSCC, predominantly in the two injuries the score 2, corresponding to 81.8% of cases in ACs and 54.5% in the CELI. The expression of IMP-3 in ACs occurred in 72.7% of cases, predominantly in 36.3% of LLSCC cases score 1. Already in the IMP-3 was expressed in 60.6% of cases, especially in 27.3% of the score of the cases 3. These results allow us to conclude that the expression of IMP3 and proliferative activity are early events in carcinogenesis independently lower lip state of change.
