In the title compound, C12H9NO3, the benzoate and furan rings are almost coplanar, making a dihedral angle of 11.68 (9)°. The twist angle between the -COO group and the benzene ring is only 2.79 (16)°. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds, forming chains along [100]. The mol-ecules stack in a herringbone fashion and inversion-related chains are linked by offset π-π inter-actions [inter-centroid distance = 3.931 (1) Å], forming ribbons propagating along the a-axis direction...

Optical differentiation is a promising tool in biomedical diagnosis mainly because of its safety. The optical parameters' values of biological tissues differ according to the histopathology of the tissue and hence could be used for differentiation. The optical fluence rate distribution on tissue boundaries depends on the optical parameters. So, providing image displays of such distributions can provide a visual means of biomedical diagnosis. In this work, an experimental setup was implemented to measure the spatially-resolved steady state diffuse reflectance and transmittance of native and coagulated chicken liver and native and boiled breast chicken skin at 635 and 808 nm wavelengths laser irradiation...

B cells are essential players in the pathogenic mechanisms of systemic lupus erythematosus (SLE). Although CD5+ B cells have been considered to play a paradoxical role in preventing, rather than inducing autoimmunity, there is no consensus agreement about the proportions of CD5+ B cells population in SLE patients. So, the aim of the present study was to assess blood concentration of CD5+ B cells in patients with SLE and to evaluate their relationship with disease activity and organ damage. We recruited 100 SLE patients and 100 healthy control subjects...

Acanthamoeba species are free-living amoebae widely distributed in the environment and which cause serious human infections. The treatment of Acanthamoeba infections is always very difficult and not constantly effective. More efficient drugs against Acanthamoeba must be developed and medicinal plants can be useful in this case. Our research focused on the examination of the anti-Acanthamoeba activity of the essential oil and the ethanolic-aqueous extract from Thymus capitatus L. The essential oil showed best activity with an IC50 of 2...

We created different TiO₂-based coatings on silicon nanowires (SiNWs) by using either thermal metallization or atomic layer deposition (ALD). The fabricated surfaces were characterized by X-ray photoelectron spectroscopy (XPS), energy dispersive X-ray spectroscopy (EDX), and reflectivity measurements. Surfaces with different TiO₂ based coating thicknesses were then used for phosphopeptide enrichment and subsequent detection by laser desorption/ionization mass spectrometry (LDI-MS). Results showed that the best enrichment and LDI-MS detection were obtained using the silicon nanowires covered with 10 nm of oxidized Ti deposited by means of thermal evaporation...

Choices are often difficult to make by patients with Alzheimer Dementia. They often become acutely confused when faced with too many options because they are not able to retain in their working memory enough information about the various individual choices available. In this case study, we describe how an essentially simple benign task (choosing a dress to wear) can rapidly escalate and result in a catastrophic outcome. We examine what went wrong in the patient/caregiver interaction and how that potentially catastrophic situation could have been avoided or defused...

The management of high-energy pilon fractures is still controversial. Open reduction and internal fixation are often associated with serious complications. Various methods have been used to treat these injuries, with variable results. The aim of this retrospective study was to analyze the clinical and radiographic outcome of the ILIZAROV technique in patients with high-energy pilon fractures. Thirty cases of distal tibia epiphysis fractures (pilon fractures) were managed from 1999 to 2012. The study group included 5 cases of open fractures...

BACKGROUND: Brain metastasis (BM) is a life-threatening event in breast cancer patients. Identifying patients at a high risk for BM can help to adopt screening programs and test preventive interventions. We tried to identify the incidence of BM in different stages and subtypes of breast cancer. PATIENTS AND METHODS: We reviewed the clinical records of 2193 consecutive breast cancer patients who presented between January 1999 and December 2010. We explored the incidence of BM in relation to standard clinicopathological factors, and determined the cumulative risk of BM according to the disease stage and phenotype...

Since 1998, the U.S. has mandated folic acid (FA) fortification of certain grain products to reduce the risk of neural tube defects. Folate intake and red blood cell (RBC) folate concentrations increased substantially post-intervention, although recent studies raise concerns about the level of ongoing benefit. This study investigated blood folate level determinants in healthy young adults, including intake of naturally occurring food folate, synthetic FA, and the interaction of naturally occurring food folate with a common missense variant in the FOLH1 gene thought to affect absorption...

We examined time of day and verbal instruction separate and combined effects on knee extensor neuromuscular adjustments, with special reference to rapid muscle force production capacity. Ten healthy male participants performed four experimental trials in counterbalanced order: morning-"hard-and-fast" instruction, evening-"hard-and-fast" instruction, morning-"fast" instruction and evening-"fast" instruction. During each experimental trial, neuromuscular performance was assessed from the completion of six maximal isometric voluntary contractions (rest = 2 minutes) of the knee extensors with concomitant quadriceps surface EMG recordings...

Microbiome projects are currently booming around the globe, enabled by advances in culture-independent microbial community analysis and high-throughput sequencing. One emerging application of microbiome science involves exploring microbial diversity in built environments, and one unexplored built environment is the pharmaceutical factory, notably factories producing antibiotics, as they could be enriched in antibiotic-resistant microbes. To examine the drug factory microbiome, we launched this interdisciplinary hypothesis-generating study to benchmark culture-independent microbiome analysis in drug manufacturing units producing antibiotics and nonantibiotic drugs, against traditional microbial identification and quantification techniques...
