3D hierarchical SnO architectures were synthesized via a one-step dissolution-precipitation route under room temperature using SnCl22H2O and Na2CO3 as initial reagents. The morphology and size of the prepared SnO structures could be easily tailored by alternating the solvent from deionized water with absolute ethanol. The SEM observation shows that the prepared 3D SnO hierarchical architectures were consisted of nanosheets. And the size of the SnO hierarchical architectures could be effectively reduced from 4 - 10 μm to 1 - 2 μm when the solvent was changed from water to ethanol while the thickness of the assembling nanosheets will be reduced from 200 - 500 nm to 20 - 30 nm at the same time...

The prorenin receptor (PRR) was originally proposed to be a member of the renin-angiotensin system (RAS), however recent work questioned their association. The present paper describes a functional link between the PRR and RAS in the renal juxtaglomerular apparatus (JGA), a classic anatomical site of the RAS. PRR expression was found in the sensory cells of the JGA, the macula densa (MD), and immunohistochemistry localized PRR to the MD basolateral cell membrane in mouse, rat, and human kidneys. MD cell PRR activation led to MAP kinase ERK1/2 signaling and stimulation of PGE2 release, the classic pathway of MD-mediated renin release...

The exfoliation energy, the energy required to peel off an atomic layer from the surface of a bulk material, is of fundamental importance in the science and engineering of two-dimensional materials. Traditionally, the exfoliation energy of a material has been obtained from first-principles by calculating the difference in the ground-state energy between (i) a slab of N atomic layers ( N ≫ 1) and (ii) a slab of N - 1 atomic layers plus an atomic layer separated from the slab. In this paper, we prove that the exfoliation energy can be obtained exactly as the difference in the ground-state energy between a bulk material (per atomic layer) and a single isolated layer...

Herein we report the efficient one- and two-carbon homologation of 1° and 2° alcohols to their corresponding homologated esters via the Mitsunobu reaction using β-carbonyl benzothiazole (BT) sulfone intermediates. The one-carbon homologation approach uses standard Mitsunobu C-S bond formation, oxidation and subsequent alkylation, while the two-carbon homologation uses a less common C-C bond forming Mitsunobu reaction. In this latter case, the use of β-BT sulfone bearing esters lowers the pKa sufficiently enough for the substrate to be used as a carbon-based nucleophile and deliver the homologated β-BT sulfone ester, this superfluous sulfone group can then be cleaved...

BACKGROUND: Topical photodynamic therapy is an established treatment modality for various dermatological conditions, including actinic keratosis. In Europe, the approved protocols for photodynamic therapy of actinic keratosis involve irradiation with either an Aktilite CL 128 lamp or daylight, whereas irradiation with the Blu-U illuminator is approved in the United States. Many other protocols using irradiation by a variety of light sources are also clinically efficient. OBJECTIVES: This paper aims to compare 10 different protocols with clinically proven efficacy for photodynamic therapy of actinic keratosis and the available spectral irradiance of the light source...

Over the past 30 years, the advent of fluoroscopically guided interventional procedures has resulted in dramatic increments in both X-ray exposure and physical demands that predispose interventionists to distinct occupational health hazards. The hazards of accumulated radiation exposure have been known for years, but until recently the other potential risks have been ill-defined and under-appreciated. The physical stresses inherent in this career choice appear to be associated with a predilection to orthopedic injuries, attributable in great part to the cumulative adverse effects of bearing the weight and design of personal protective apparel worn to reduce radiation risk and to the poor ergonomic design of interventional suites...

In the printing, coating and ink industries, photocurable systems are becoming increasingly popular and multi-functional acrylates are one of the most commonly used monomers due to their high reactivity (fast curing). In this paper, we use molecular dynamics and graph theory tools to investigate the thermo-mechanical properties and topology of hexanediol diacrylate (HDDA) polymer networks. The gel point was determined as the point where a giant component was formed. For the conditions of our simulations, we found the gel point to be around 0...

This perspective reviews our recent efforts towards the self-assembly of polynuclear clusters with ditopic and tritopic multidentate ligands HL1 (2-phenyl-4,5-bis{6-(3,5-dimethylpyrazol-1-yl)pyrid-2-yl}-1H-imidazole) and H2L2 (2,6-bis-[5-(2-pyridinyl)-1H-pyrazole-3-yl]pyridine), both of which are planar and rigid molecules. HL1 was found to be an excellent support for tetranuclear [Fe4] complexes, [FeII4(L1)4](BF4)4 ([FeII4]) and [FeIII2FeII2(L1)4](BF4)6 ([FeIII2FeII2]). The homovalent system was found to exhibit multistep spin crossover (SCO), while the mixed-valence [FeIII2FeII2] complex shows wavelength-dependent tuneable light-induced excited spin state trapping (LIESST)...

REVIEW
Donald L Trump, Jeanny B Aragon-Ching
Signaling through the vitamin D receptor has been shown to be biologically active and important in a number of preclinical studies in prostate and other cancers. Epidemiologic data also indicate that vitamin D signaling may be important in the cause and prognosis of prostate and other cancers. These data indicate that perturbation of vitamin D signaling may be a target for the prevention and treatment of prostate cancer. Large studies of vitamin D supplementation will be required to determine whether these observations can be translated into prevention strategies...

INTRODUCTION: The specificity of personnel exposure, which distinguishes nuclear medicine, is associated with the form of the radiation source used, and this often requires performing manual procedures while using radioactive isotopes. The variety of radionuclides and medical procedures, and the yearly increase in the number of patients, as well as the change of the individual dose limit for the lens of the eye from a value of 150 mSv per year to a level of 20 mSv, means that issues of eye lens routine dosimetry become interesting from the radiation protection point of view...

ABSTRACTBackground:There is limited evidence regarding how the decision evolves about whether and when it is best for a person with dementia to move to a care home. The factors leading to the timing of the decision remain particularly unclear. This systematic review of existing literature aims to gain an understanding of the decision-making timing and process to distinguish the drivers of these decisions, and to identify if there is an "optimal" or best time (if any) for a person with dementia to move to a care home...

Recent evidences suggest that hypogonadism is an important risk factor for lower urinary tract symptoms and benign prostatic hyperplasia. Several papers have discussed the role of chronic inflammation in the development of BPH, which may be modulated by the hypogonadal state. Soluble urokinase-type plasminogen activator receptor (suPAR), known protein marker of systemic inflammation, can be assayed in the seminal plasma and represents a reliable and sensitive marker of inflammation for the male accessory gland inflammation (MAGI)...

Most existing signal timing models are aimed to minimize the total delay and stops at intersections, without considering environmental factors. This paper analyzes the trade-off between vehicle emission and traffic efficiencies on the basis of the field data. First, considering the different operating modes of cruising, acceleration, deceleration, and idling, the field data of emissions and GPS are collected to estimate emission rates for the heavy-duty and light-duty vehicles. Second, multi-objective signal timing optimization model is established based on a genetic algorithm to minimize delay, stops, and emissions...
