Bei Wang, Rongju Sun, Wei Chen, Tanshi Li
 Despite recent advances, treatment of acute superior mesenteric artery embolism (SMAE) in emergency is still very difficult. The comparative rarity, the difficulty of early diagnosis, and the extremely high mortality of SMAE give us the sufficient reasons to report our successful experience in curing a patient with acute SMAE. In the present case, the patient was diagnosed early without evidence of intestinal necrosis. The diagnosis of SMAE was verified by computed tomography angiography (CTA). A comprehensive treatment was immediately employed including a combination of intra-arterial thrombolysis and embolectomy operation with emergent laparotomy...

Herba Epimedii (Yinyanghuo or Horny Goat Weed) is a traditional Chinese medicine widely used in treating osteoporosis. As the major active component, icariin is intensively investigated in the prevention and treatment of osteoporosis in ovariectomized rats. However, misleading conclusions can be generated in animal studies with various experimental designs. Therefore, a systematic review and meta-analysis was performed to evaluate the efficacy of icariin against osteoporosis in ovariectomized rats. PubMed, EMBASE and Chinese National Knowledge Infrastructure databases were searched to identify studies of icariin in ovariectomized rats...

Thiobacillus is a genus of Gram-negative, rod-shaped and autotrophic Betaproteobacteria. They catalyze the dissimilatory oxidation of elemental sulfur and reduced inorganic sulfur compounds. Whereas more than 30 species have been known in this genus, most were never reliably or effectively published. The rest were either reclassified into Thiomonas, Paracoccus, Starkeya, Sulfuriferula, Halothiobacillus, Thermithiobacillus or Acidithiobacillus, were lost from culture. Most of Thiobacillus species are obligate autotrophs via elementary sulfur, thiosulfate or polythionates as energy sources...

Major hurdle faced by many physicians in treating various respiratory tract infections and lung carcinomas is their late or mis-diagnosis. In most respiratory tract infections the manner of infection is not completely understood. Similarly, various lung carcinomas are diagnosed at advance stages at which not only the treatment possibilities are narrowed but the chances of survival are also reduced. So, for the sake of better treatment, the quick and improved diagnostic strategies are suggested. Protein biomarkers fully fit the description in this regard as they have shown great potential in specific diagnosis of many respiratory diseases and also have shown capability in timely pin pointing different stages of lung carcinomas...

Melanoma is the most malignant skin cancer. Curcumin has shown to have therapeutic effects when used in the treatment of malignant diseases. However, the precise molecular mechanisms of its action are not fully elucidated. In this research, we hypothesized that reactive oxygen species (ROS) play a key role in curcumin induced DNA damage, apoptosis and cell dead. To test our hypothesis, cytotoxic, genotoxic, apoptotic, ROS generating and mitochondrial membrane potential (MMP) of curcumin on mouse melanoma cancer cells (B16-F10) and fibroblastic normal cells (L-929) were investigated...
