We consider the evolution of viscous fluids in a 2D horizontally periodic slab bounded above by a free top surface and below by a fixed fiat bottom. This is a free boundary problem. The dynamics of the fluid are governed by the incompressible stationary Navier-Stokes equations under the influence of gravity and the effect of surface tension. We develop the global theory of solutions in low regularity Sobolev spaces for small data by nonlinear energy estimates.

BACKGROUND In clinical practice, community-acquired pneumonia(CAP) can be complicated by rhabdomyolysis(RM), and RM symptoms are mild and easily missed during diagnosis. Moreover, available data on RM induced by CAP are mainly from case reports. Due to the relatively low incidence of CAP-induced RM, more systematic studies are required to understand the characteristics of CAP-induced RM to improve its diagnosis and *** To investigate the clinical characteristics of patients with CAP-induced *** This was a retrospective study of 11 patients with CAP-induced RM. Baseline characteristics, diagnostic work-up, and laboratory test results were summarized and compared with those of 48 patients with exercise-induced RM admitted during the same *** CAP-induced RM was more common in men, and affected older patients compared to those with exercise-induced RM. However, the average age of the patients in this study was lower than the age of peak incidence of CAP in adults in China. The major clinical manifestations were high fever and respiratory symptoms. RM symptoms were mild and often overlooked. Patients with CAP-induced RM had elevated inflammatory parameters, respiratory alkalosis,relatively low serum potassium levels and often had abnormalities in hepatic and renal function and cardiac enzymes. Compared with the exercise group, the pneumonia group had lower levels of creatine kinase and myoglobin, a higher incidence of acute kidney injury, and worse renal function and *** events were mainly related to the severity of *** CAP-induced RM has different clinical characteristics from those of exerciseinduced RM. Early detection and treatment could reduce complications and consequently shorten the treatment course.

Distributions of triplet separator lengths for two bacterial complete genomes are analyzed. The theoretical distributions for the independent random sequence and the first-order Markov chain are derived and compared with the distributions of the bacterial genomes. A prominent double band structure, which does not exist in the theoretical distributions, is observed in the bacterial distributions for most triplets.

MicroRNAs （miRNAs） play important roles in post-transcriptional gene silencing by directing target mRNA cleavage or translational inhibition. Currently, hundreds of miRNAs have been identified in plants, but no report has been published of wild soybean （Glycine soja Sieb）. We constructed a small-RNA library consisting of 2 880 sequences with high quality, in which 1 347 were 19-24 nt in length. By utilizing the miRNA, Rfam and domesticated soybean expressed sequence tag database, we have analyzed and predicted the secondary structure of these small RNAs. As a result, t5 conserved miRNA candidates belonging to eight different families and nine novel miRNA candidates comprising eight families were identified in wild soybean seedlings. All these miRNA candidates were validated by northern blot and the novel candidates expressed in a tissue-specific manner. Furthermore, putative target genes were predicted for novel miRNA candidates and two of them were verified by 5＇-rapid amplification of cDNA ends experiments. These results provided useful information for miRNA research in wild soybean and plants.

In vivo imaging is creating great opportunities for disease diagnosis as a research tool. Probes are usually used to observe physiological structures in vivo clearly. Recent progresses of nanoprobes are important for the generation of high resolution and high contrast images required by accurate and precision disease diagnosis. In vivo self-assembled peptide(SAP) nanoprobes are playing major roles in in vivo imaging by modularity of design, high imaging contrast, response to the location of the lesion, and long-time retention in the lesion. And the response to lesion and long-term retention in there can enhance imaging sensitivity and specificity of in vivo SAP nanoprobes. Therefore, in vivo SAP nanoprobes are simple ancillary contrast entities to optimize the imaging effect. In this review, the recent progress of in vivo SAP nanoprobes for in vivo imaging, from molecular design of peptides to biomedical and clinical applications including disease diagnosis and disease-related molecular imaging is systematically summarized. We evaluate their ability, including sensitivity and specificity to provide relevant information under preoperative and during surgery circumstances and critically their likelihood to be clinically translated. Finally, a brief outlook on remaining challenges and potential directions for future research in this area is presented.
