No markedly significant differences of flat foot frequencies between the Spanish and Italian series were found across centuries. However, we noticed a notable increase of the prevalence of flat foot in the contemporary collection, possibly due to the consequences of a rise in life expectancy and modern styles of footwear.This study aims to develop age-at-death standards for Valley of Mexico skeletal collections. Using 159 individuals, with a dental age-at-death between 0 to 15 years, we develop linear and quadratic inverse regression models of age-at-death estimation between dental age and the diaphyseal length of the six long bones. A blind test for both regressions was performed, also a regression developed for a Maya group was carried out. We also compared skeletal growth of our sample by applying regressions developed for Maya and North American populations to assess the magnitude of the differences among ethnically unrelated populations. Our regressions yielded a close correlation between the diaphyseal length and dental age, especially femur and radius. It is noticeable that the disparities between younger and older age categories, the latter presenting larger standard deviations. Quadratic regression fitted better than linear and Maya regressions, and the differences of age-at-death distributions are significant. The skeletal growth curve of the Valley of Mexico is statistically different from other Native American groups. We conclude that for the present standards, despite the high degree of variance, the quadratic regression is a better applicable age estimator, when it is applied to biologically close populations.Purpose Osteoporosis is the most widespread systemic disease of the skeleton. According to estimated data for Poland, it affects ca. 3 million people. Although the disease is multifactorial, with significant influence of environmental factors on the increase of the risk of its occurrence, genetic factors play an important role in its pathogenesis. The aim of this study was an analysis of the relation of the ApaI, BsmI and TaqI polymorphisms of the VDR gene, with bone mineral density measured in lumbar spine and/or in proximal femur in a group of polish women. Methods The study included 135 women at the postmenopausal age from the area of central Poland. BMD was measured at the hip and/or at the lumbar spine, using dual-energy X-ray absorptiometry. The influence of the selected VDR genotypes on bone mineral density was studied using the ApaI, the BsmI and the TaqI restriction enzymes. Lifestyle information was obtained via questionnaire. Results Women with the 'bb' genotype showed lower BMD values of the hip (Total BMD value) comparing to patients with 'BB' or 'Bb' genotypes. We did not observe similar correlation for the lumbar spine. The remaining polymorphisms (ApaI and TaqI) did not demonstrate a significant relation with the differentiation of the mean BMD values obtained from the hip nor from lumbar vertebrae. Conclusion The present study has demonstrated that the BsmI polymorphism of the vitamin D receptor gene is a factor of bone mineral density changes in postmenopausal women from Poland.Anion-π based compounds, materials, and processes have gained significant interest due to the diversity of their aesthetic non-covalent synthons, and thanks to their significance in biological systems, catalytic processes, anion binding and sensing, or the supramolecular organization of hierarchical architectures. While systems based on typical inorganic anions or organic residues have been widely reviewed in recent years, those involving anionic d metal comlexes as the main components have been treated with a rather secondary interest. However, actively exploring the new systems of the latter type we have recognized systematic advances in the field. As a result, in the current review we describe the landscape that has recently emerged. Focusing on the established groups of π-acidic species, i.e. polycarbonitirles, polyazines, polyazine N-oxides, diimide derivatives, fluoroarenes, and nitroarenes, we explore and discuss anion-π crystal engineering together with the structure-property schemes important from the standpoint of charge transfer (CT) and electron transfer (ET), magnetism, luminescence, reactivity and catalysis, and the construction of core-shell crystalline composites.Mung beans possess health benefits related to their bioactive ingredients, mainly flavonoids, which are highly concentrated in the coat. However, the anti-aging effects of mung beans are rarely reported. In this work, we found that mung bean coat extract (MBCE), rich in vitexin and isovitexin, extended the lifespan and promoted the health of Caenorhabditis elegans (C. elegans) without any disadvantages. Selleck PFI-2 Moreover, MBCE enhanced the resistance to heat and oxidation of C. elegans by reducing the accumulation of intracellular reactive oxygen species and up-regulating the expression of stress-resistant genes or proteins. Further studies demonstrated that MBCE improved longevity, stress-resistance and fitness by mediating the mitochondrial function, mimicking calorie restriction, and altering histone modification. These findings provide direct evidence for the anti-aging effects of mung beans and new insights into the innovations and applications of mung beans for the healthcare industry.Tamm-Horsfall protein (THP) is a high-abundance urinary protein. Although its functions have been studied for years, several aspects of these remain unclear. To achieve more knowledge on THP functions, an effective isolation/purification method providing a high yield and high purity is required. This is the first report that applied tandem fast protein liquid chromatography (FPLC) (by combining Mono Q anion-exchange with Superdex 200 size-exclusion columns in a tandem manner) to isolate intact THP from human urine. Its efficiency was then systematically compared with that of two conventional methods, diatomaceous earth (DE) adsorption and salt precipitation. The first ever systematic comparisons among the three methods revealed that, while Mono Q-Superdex 200 tandem FPLC offered the lowest %yield and was most time-consuming, it provided substantially high %purity and could selectively purify the monomeric and aggregated forms of urinary THP. On the other hand, DE adsorption provided the highest %yield and %purity, whereas salt precipitation offered the lowest %purity.
