Abstract
This paper proposes a new method for an automatic detection of a resolution of a scale or a ruler with graduation marks in the shoeprint images. The method creates a vector of the correlations estimated from the co-occurrence matrices for every row in a shoeprint image. The scale resolution is estimated from maxima in Fourier spectrum of the correlations' vectors. The proposed method is evaluated on over 500 images taken at crime scenes and in a forensics laboratory. The experimental results indicate the possibility of applying the proposed method to automatically estimate the scale resolution in forensic images. The automatic detection of a scale resolution could be used to automatically rescale a forensic image before the printing this image in "one-to-one" scale. Furthermore, the proposed method could be used to automatically rescale images to an equal scale thus allowing to compare the images digitally.

Abstract
A new NMR experiment (Destruction of Interfering Satellites by Perfect Echo Low-pass filtration, DISPEL) is introduced that facilitates the analysis of low-level components in high dynamic range mixtures by suppressing one-bond 13C satellite signals in 1H spectra. Since the natural abundance of 13C is around 1.1%, these satellites appear at 0.54% of the intensity of a parent peak, mimicking and often masking impurity signals. The new experiment suppresses one-bond 13C satellite signals, with high efficiency, at negligible cost in signal-to-noise ratio, and over a wide range of one-bond coupling constants, without the need for broadband 13C decoupling.

Abstract
Intrinsic Optical Signal (IOS) imaging has been used extensively to examine activity-related changes within the cerebral cortex. A significant technical challenge with IOS imaging is the presence of large noise, artefact components and periodic interference. Signal processing is therefore important in obtaining quality IOS imaging results. Several signal processing techniques have been deployed, however, the performance of these approaches for IOS imaging has never been directly compared. The current study aims to compare signal processing techniques that can be used when quantifying stimuli-response IOS imaging data. Data were gathered from the somatosensory cortex of mice following piezoelectric stimulation of the hindlimb. The effectiveness of each technique to remove noise and extract the IOS signal was compared for both spatial and temporal responses. Careful analysis of the advantages and disadvantages of each method were carried out to inform the choice of signal processing for IOS imaging. We conclude that spatial Gaussian filtering is the most effective choices for improving the spatial IOS response, whilst temporal low pass and bandpass filtering produce the best results for producing temporal responses when periodic stimuli are an option. Global signal regression and truncated difference also work well and do not require periodic stimuli.

Abstract
BACKGROUND Hip fractures cause increased mortality and disability and consume enormous healthcare resources. Only 46% of hip fracture patients have osteoporosis at the total hip according to dual-energy X-ray absorptiometry (DXA) measurement. Cortical porosity increases with ageing and is believed to be important for bone strength. OBJECTIVE To investigate whether older women with hip fracture have higher cortical porosity than controls, and if so whether this difference is independent of clinical risk factors and areal bone mineral density (aBMD). METHODS From an ongoing population-based study, we identified 46 women with a prevalent X-ray-verified hip fracture and 361 control subjects without any fractures. aBMD was measured with DXA. High-resolution peripheral quantitative computed tomography was used to measure bone microstructure at the standard (ultradistal) site and at 14% (distal) of the tibial length. RESULTS Women with a previous hip fracture had lower aBMD at the femoral neck (-11.8%) and total hip (-14.6%) as well as higher cortical porosity at the ultradistal (32.1%) and distal (29.3%) tibia compared with controls. In multivariable logistic regression analysis, with adjustment for covariates (age, height, weight, smoking, calcium intake, physical activity, walk time, oral glucocorticoids, parental hip fracture, rheumatoid arthritis, previous fall, current bisphosphonate treatment and femoral neck aBMD), cortical porosity at the ultradistal [odds ratio per standard deviation increase (95% confidence interval) 2.61 (1.77-3.85)] and distal [1.57 (1.12-2.20)] sites was associated with prevalent hip fracture. CONCLUSION Cortical porosity was associated with prevalent hip fracture in older women independently of femoral neck aBMD and clinical risk factors.

Abstract
NMR is the most versatile tool for the analysis of organic compounds and, in combination with Diffusion-Ordered Spectroscopy ('DOSY'), can give information on compounds in complex mixtures without the need for physical separation. In mixtures where the components' diffusion coefficients are nearly identical, for example because of similar sizes, Matrix-Assisted DOSY ('MAD') can help separate the signals of different constituents, resolving their spectra. Unfortunately, DOSY (including MAD) typically fails where signals overlap, as is common in 1 H NMR. Using 19 F NMR avoids such problems, because the great sensitivity of the 19 F chemical shift to local environment leads to very well-dispersed spectra. Another advantage is the absence of any 19 F background signals from the matrices typically used, avoiding interference with the analyte signals. In this study, differentiation among fluorophenol and fluoroaniline isomers was evaluated using normal and reverse micelles-of sodium dodecyl sulfate (SDS), cetyltrimethylammonium bromide (CTAB) and dioctyl sodium sulfosuccinate (AOT)-as matrices. These surfactants provide useful diffusion separation in these difficult mixtures, with all the solutes interacting with the matrices to different extents, in some cases leading to differences in diffusion coefficient of more than 30%. The best matrices for separating the signals of both acid and basic species were shown to be AOT and CTAB, which are useful over a wide range of surfactant concentration.

Abstract
BACKGROUND Chronic nonhealing or recurrent inflammatory lesions, reminiscent of infection but recalcitrant to antibiotic therapy, generally characterize biofilm-driven diseases. Chronic lesions of hidradenitis suppurativa (HS) exhibit several characteristics, which are compatible with well-known biofilm infections. OBJECTIVES To determine and quantify the potential presence of bacterial aggregates in chronic HS lesions. METHODS In 42 consecutive patients with HS suffering from chronic lesions, biopsies were obtained from lesional as well as from perilesional skin. Samples were investigated using peptide nucleic acid-fluorescence in situ hybridization in combination with confocal laser scanning microscopy. In addition, corresponding histopathological analysis on haematoxylin and eosin slides was performed. RESULTS Biofilms were seen in 67% of the samples of chronic lesions and in 75% of the perilesional samples. The mean diameter of aggregates in lesional skin was significantly greater than in perilesional skin (P = 0·01). Large biofilms (aggregates > 50 μm in diameter) were found in 42% of lesional samples and in only 5% of the perilesional samples (P = 0·009). The majority of the large biofilms were situated in sinus tracts (63%) or in the infundibulum (37%). The majority of the sinus tract samples (73%) contained active bacterial cells, which were associated with inflammation. CONCLUSIONS This study suggests that biofilm formation is associated with inflammation of chronic HS lesions. The aggregates most likely occur as a secondary event, possibly due to predisposing local anatomical changes such as sinus tracts (tunnels), keratinous detritus and dilated hair follicles.

Abstract
Abstract
Increasing evidence supports the benefit of identifying the BRCA1 and BRCA2 germline mutation status in early breast cancer. Germline mutations in these two genes are treatment predictive for the benefit of risk reducing surgical interventions of the contralateral breast and the ovaries and fallopian tubes, in early breast cancer (Metcalf 2014; Domchek 2010). Furthermore, they may possibly also be treatment predictive for the effect of certain types of medical interventions (Tutt SABCS 2014).
In order to provide the patient with the opportunity to take BRCA test results into account already when planning primary treatment, BRCA testing and cancer genetic counseling needs to be initiated and performed early during the diagnostic and treatment related process in newly diagnosed breast cancer cases. Special attention needs to be taken to the fact that the test results may affect not only the patient, but also her or his relatives. We have observed that the clinical efficacy of BRCA-screening criteria may be surprisingly low, leaving a substantial number of BRCA-carriers undetected in spite of intense contacts with health care providers (Unpublished results).
BRCAsearch (ClinicalTrials.gov Identifier: NCT02557776) is a population based study including new invasive breast cancer cases at three hospitals in the South of Sweden. Patients are invited to perform BRCA1 and BRCA2 germline mutation analysis at time of primary treatment after written study information and written genetic counseling, irrespective of family history, age or clinical phenotype. The primary end-points of the study include the rate of BRCA mutations in newly diagnosed breast cancer in South Sweden, the fraction of patients that accept inclusion in the study, and the rate of mutation positive patients that do not fulfill clinical criteria for BRCA mutation screening. Secondary end-points include the perception among patient of the intervention and testing procedures, the types of questions the patients present during the process and psychosocial outcome among carriers and non-carriers.
In May 2016 about 400 patients have been included in the study, whereof 333 have been analyzed for BRCA germline mutations. The accrual target of the study is 500 patients, which will be reached during the fall of 2016. At the meeting, the BRCA1 and BRCA2 mutation rates will be presented, as well as the acceptance rate of the study among patients approached, and the fraction of mutation positive patients that do not fulfill current BRCA1 and BRCA2 mutation screening criteria, and whose positive mutation status therefore would have been missed if clinical selection criteria had been applied.
The results of the study will be used to define selection criteria for BRCA-mutation screening in new breast cancer cases, and the design of screening procedures with an appropriate clinical effectiveness.Increasing evidence supports the benefit of identifying the BRCA1 and BRCA2 germline mutation status in early breast cancer.

Abstract
Peptide dendrimers are a novel class of precisely defined macromolecules of emerging interest. Here, we describe the synthesis, structure, binding affinity, receptor selectivity, functional activity, and antinociceptive properties of oxytocin-related dendrimers containing up to 16 copies of [Lys8]-oxytocin or LVT. These were generated using a copper(i)-catalyzed azide–alkyne cycloaddition (CuAAc) reaction with azido-pegylated LVT peptides on an alkyne–polylysine scaffold. 2D NMR analysis demonstrated that each attached LVT ligand was freely rotating and maintained identical 3D structures in each dendrimeric macromolecule. The binding affinity Ki at the oxytocin receptor increased approximately 17-, 12-, 3-, and 1.5-fold respectively for the 2-, 4-, 8-, and 16-mer dendrimeric LVT conjugates, compared with monomer azido-pegylated LVT (Ki = 9.5 nM), consistent with a multivalency effect. A similar trend in affinity was also observed at the related human V1a, V1b, and V2 receptors, with no significant selectivity change observed across this family of receptors. All LVT dendrimers were functionally active in vitro on human oxytocin receptors and inhibited colonic nociceptors potently in a mouse model of chronic abdominal pain.
