INTRODUCTION: The impact of socioeconomic status (SES) on tooth mineralization has seldom been evaluated. This is important because SES can be used as a proxy for quantifying factors in the environmental that can impact mineralization but that can be difficult to measure directly, such as nutrition. OBJECTIVE: The objective of this study was to examine the effects of SES on third molar mineralization, using a sample of children, adolescents and young adults from Porto, Portugal...

Many national and international institutions advocate approaching violence as a problem in public health and preventive medicine, in a manner similar to the way we address other disabling and life-threatening pathologies such as cancer, diabetes, and heart disease. Prevention by a health model requires an ecological perspective. Previous work has found evidence that economic factors, including unemployment and relative poverty, as well as political culture and values, may affect violent death rates, including homicide and suicide...

Japanese Society of Radiological Technology (JSRT) standard digital image database contains many useful cases of chest X-ray images, and has been used in many state-of-the-art researches. However, the pixel values of all the images are simply digitized as relative density values by utilizing a scanned film digitizer. As a result, the pixel values are completely different from the standardized display system input value of digital imaging and communications in medicine (DICOM), called presentation value (P-value), which can maintain a visual consistency when observing images using different display luminance...

Previous human study suggested that fresh-frozen intervertebral disc allograft transplantation can relieve neurological symptoms and restore segmental kinematics. Before wide clinical application, research into the pathophysiology of the postoperative disc allograft is needed. One important question that remains to be answered in disc allografting is the healing process of the host-graft interface and the subsequent change of the endplates. With the goat model for lumbar disc allografting, histology, micro-computed tomography analysis, scanning electron microscopy and energy-dispersive X-ray spectroscopy mapping were applied to evaluate the healing of the host-graft interfaces, the remodelling of subchondral bone, and the changes of the bony and cartilaginous endplates after transplantation...

Latin America has 23 countries ranging from Mexico, Central America, South America and the Caribbean, of these 19 countries are considered by the WHO as countries with high and very high risk, one of the similarities of our countries is poor access to services health and medicine, resulting from poor government investment in health as the amount used in this sector occupies only the best 3% of the national budget and gross domestic product.Thus we know that the prevalence of hypertension varies widely from country to country and from city to city, presenting in Guatemala a prevalence of 40%, while in other countries in the area ranges between 25 and 35%, most complicated problem is that within the same country as the population this prevalence can vary greatly and have a different impact between populationsTherefore we know that the impact of cardiovascular disease within the range of non-communicable diseases occupies at least 30% and of these about 70% occupied countries of low and moderate income...

Dear Editor I read with great interest the manuscript titled "A New Panel of Blood Biomarkers for the Diagnosis of Mild Traumatic Brain Injury/Concussion in Adults" by Shan R, et al, published in the January issue of the Journal. (1) I do have some questions. The key to marker discovery studies is a precise and accurate description of how the population was identified, including controls. I have significant concerns about the control population in the manuscript. In the presentation the characteristics of the control group are unclear, described only as "not patients in the ED" and with the same exclusion criteria of the other cohorts...

Sentinel lymph node biopsy is a crucial part of staging intermediate and thick melanoma. Lymphatic drainage from a tumor site can be highly variable, especially on the head, neck, and trunk. SPECT/CT fuses nuclear medicine and x-ray CT images to produce images with high anatomic detail. At our institution, SPECT/CT is performed routinely in addition to planar imaging. This article presents examples where SPECT/CT has proven helpful in image interpretation.

The bacterium Lactococcus lactis is widely used in food production and in medical applications, and is considered safe for human and animal use. However, studies have also linked Lactococcus bacteria to infection. For example, certain variants of Lactococcus species have been associated with bovine mastitis (e.g., Lactococcus lactis and Lactococcus garvieae). In this study, we investigated an outbreak of bovine mastitis thought to be associated with Lactococcus bacteria by using microbiological and molecular techniques...

Photoaffinity labels are powerful tools for dissecting ligand-protein interactions, and have a broad utility in medicinal chemistry and drug discovery. Traditional photoaffinity labels work through non-specific C-H/X-H bond insertion reactions with the protein of interest by the highly reactive photo-generated intermediate. Herein, we report a new photo-affinity label, 2-aryl-5-carboxytetrazole (ACT) that interacts with the target protein via a unique mechanism in which the photo-generated carboxynitrile imine reacts with a proximal nucleophile near the target active site...

Zuotai (gTso thal) is one of the famous drugs containing mercury in Tibetan medicine. However, little is known about the chemical substance basis of its pharmacodynamics and the intrinsic link of different samples sources so far. Given this, energy dispersive spectrometry of X-ray (EDX), scanning electron microscopy (SEM), atomic force microscopy (AFM), and powder X-ray diffraction (XRD) were used to assay the elements, micromorphology, and phase composition of nine Zuotai samples from different regions, respectively; the XRD fingerprint features of Zuotai were analyzed by multivariate statistical analysis...

The synthesis of mono- and difunctionalized [Re(η(6)-C6H5R)(η(6)-C6H6-nRn)](+) (n = 0, 1; R = COOH, Br) complexes starting from [Re(η(6)-benzene)2](+) is described. The lithiation of [Re(η(6)-benzene)2](+) with n-BuLi leads preferentially to the neutral, alkylated product [Re(η(6)-C6H6)(η(5)-C6H6-Bu)] but not to the expected deprotonation of the arene ring. Deprotonation/lithiation with LDA gave the mono- and the dilithiated products in situ. Their reactions with 1,1,2,2-tetra-bromoethane (TBE) or with CO2, respectively, gave [Re(η(6)-C6H5Br)(η(6)-C6H6)](+), [Re(η(6)-C6H5Br)2](+), or [Re(η(6)-C6H5COOH)(η(6)-C6H6)](+), [Re(η(6)-C6H5COOH)2](+)...

Several terbium isotopes are suited for diagnosis or therapy in nuclear medicine. Tb-155 is of interest for SPECT imaging and/or Auger therapy. High radionuclide purity is mandatory for many applications in medicine. The quantification of the activity of the produced contaminants is therefore as important as that of the radionuclide of interest. The experiments performed at the ARRONAX cyclotron (Nantes, France), using the deuteron beam delivered up to 34MeV, provide an additional measurement of the excitation function of the Gd-nat(d,x)Tb-155 reaction and of the produced terbium and gadolinium contaminants...
