BACKGROUND: Sleeve gastrectomy is a relatively new procedure that developed as a result of rapid innovation in the field of bariatric surgery. As with any newly developed operation, there is a learning curve that potentially can be associated with higher morbidity. Real-time surgical mentoring reduces the learning curve effect but can be time intensive for the mentor. The aim of this initiative was to evaluate the feasibility, effectiveness, and satisfaction of surgical telementoring for laparoscopic sleeve gastrectomy...

STAT3 is considered to be a key molecule to mediating tumor-induced immunosuppression in various manners at tumor sites, by acting through immune-regulatory cytokines derived from the tumor cells. Specific anti-STAT3 inhibitors have been developed using nude mouse models transplanted with human tumor cells. However, mouse systems cannot accurately represent the human immune response induced by STAT3 inhibitors, and more humanized therapeutic model based on human immune cells and tumors are needed. In the present study, an immune-deficient NOG mouse with the deletion of both MHC-class I and class II genes, an MHC-double knockout mouse (dKO-NOG), was developed and used to establish humanized immunotherapeutic model...

Marine oil spills are typically followed by complex clean-up and monitoring operations of the shorelines affected. In this regard, determination of the changes in the chemical composition of the spilled product is crucial for evaluation purposes. The "GC-MS fingerprint" approach requires the identification of several key parameters in order to differentiate between weathering processes. In this context, we performed a 900-day study (eight sampling campaigns) of natural attenuation on a rocky shore affected by a heavy fuel oil spill...

Climate change is rapidly altering many aquatic systems, and life history traits and physiological diversity create differences in organism responses. In addition to biological diversity, habitat diversity may be expressed on small spatial scales, and it is therefore necessary to account for variation among both species and locations when evaluating climate impacts on biological communities. Here, we investigated the effects of temperature and spatial heterogeneity on long-term community composition in a large boreal lake...

BACKGROUND: Currently, most patients undergoing laparoscopic cholecystectomy (LC) in Switzerland are inpatients for 2-3 days. Due to a lack of available hospital beds, we asked whether day-case surgery would be an option for patients in central Switzerland. The questions of acceptability of outpatient LC and factors contributing to the acceptability thus arose. METHODS: Hundred patients suffering from symptomatic cholecystolithiasis, capable of communicating in German, and between 18 and 65 years old, were included...

Mannose receptor is considered as a hallmark of M2-oriented tumor-associated macrophages (TAMs), but its utility in TAMs was rarely reported. Therefore, deoxymannose (DM), a high-affinity ligand of mannose receptor, was labeled with near-infrared dye cyanine 7 (Cy7), and its feasibility of targeted imaging on TAMs was evaluated in vitro and in vivo. The Cy7-DM was synthesized, and its binding affinity with induced TAMs in vitro, whole-body imaging in xenograft tumor mouse model in vivo, and the cellular localization in dissected tissues were evaluated...

To overcome the deficiency of rapid elimination from blood, the truncated human recombinant ciliary neurotrophic factor was formulated by site-specific attachment of different-sized PEG-maleimide or by cross-linking with human transferrin through a hetero-bi-functional PEG linker (NHS-PEG5k-MAL). The PEGylated CNTF was purified by a two-step chromatography procedure and the transferrin coupling CNTF conjugate was separated through an elegant protocol. The conjugation site on CNTF was identified by peptide mapping analysis and validated that the linkage of the conjugates was specifically happened to Cys17 residue...

Influenza and other acute respiratory infections are of great concern for public health, causing excessive morbidity and mortality throughout the world. Influenza virus A(H2N2), which caused a pandemic of so called "Asian flu" in 1957 was expelled from the human population by the new pandemic virus subtype H3N2 in 1968, however, influenza A(H2) viruses continue to circulate in wild birds and poultry. The lack of immunity in human population and the continued circulation of influenza A(H2) among animals makes emergence of a new pandemic virus possible...

BACKGROUND: Policy-makers argue that emergency department (ED) visits for conditions preventable with high-quality outpatient care contribute to waste in the healthcare system. However, access to ambulatory care is uneven, especially for vulnerable populations like minorities, the poor and those with limited health literacy. The impact of limited health literacy on ED visits that are preventable with timely, high-quality ambulatory care is unknown. OBJECTIVE: To determine the association of health literacy and preventable ED visits...

Bone morphogenetic protein-2 (BMP-2) is an osteoinductive growth factor used clinically to induce bone regeneration and fusion. Some complications associated with BMP-2 treatment have been attributed to rapid release of BMP-2 from conventional collagen scaffolds, motivating the development of tunable sustained-release strategies. We incorporated BMP-2-binding heparin microparticles (HMPs) into a hydrogel scaffold to improve spatiotemporal control of BMP-2 delivery to large bone defects. HMPs pre-loaded with BMP-2 were mixed into alginate hydrogels and compared to hydrogels containing BMP-2 alone...
