Geological Survey of Slovenia, Dimičeva ulica 14, 1000, Ljubljana, Slovenia.

Street dust (SD) acts as a sink and a source of atmospheric particulate matter, which is especially significant in urban environments. World studies of natural and anthropogenic impacts on the elemental composition of SD are generally limited to specific areas or case studies. The objectives of this study are to determine the impacts of different anthropogenic atmospheric dust emitters and natural factors on the chemical composition of SD, and to define sources of variance in elemental composition of SD, temporal variations and geochemical associations of elements on large number of samples, collected in different time periods, anthropogenic environments and geological settings.

Ambient geochemical baselines for trace elements in Chernozems-approximation of geochemical soil transformation in an agricultural area.

Environ Monit Assess 2018 Dec 15;191(1):19. Epub 2018 Dec 15.

Wrocław University of Environmental and Life Sciences, Institute of Soil Science and Environmental Protection, Grunwaldzka 53, 50-357, Wrocław, Poland.

The legal regulatory/action levels of trace elements in soils are established at high concentrations, at which the crucial functions of soil are at risk or are eliminated. However, concentrations below these action levels, but above presumed natural levels, may also limit particular ecosystem services, including organic food production. Thus, defining the (ambient) background concentrations is an essential part of environmental or health risk assessment, e. Read More

The maternal reward system in postpartum depression.

Arch Womens Ment Health 2018 Dec 15. Epub 2018 Dec 15.

Department of Psychology, The Ohio State University, 1835 Neil Avenue, Columbus, OH, USA.

The experience of motherhood is most often emotionally positive and rewarding, but for many new mothers suffering from postpartum depression (PPD), this is not the case. Preclinical and clinical research has sought to uncover brain changes underlying PPD in order to gain a better understanding of how this disorder develops. This review focuses on the mesolimbic dopamine system, particularly the ventral tegmental area-nucleus accumbens pathway which has been implicated in the regulation of critical functions disrupted in PPD including mood, motivation, and mothering.

Department of Neurosurgery, Sanjay Gandhi Postgraduate Institute of Medical Sciences, Rae Bareli Road, Lucknow, India.

Background: Pathological laughter is inappropriate, involuntary and unmotivated laughter episodes which may or may not be associated with mirth or amusement. Though associated with many diffuse brain pathologies, its association with intracranial focal mass lesions causing ventrolateral brainstem compression like petroclival meningioma is very rare. The exact pathophysiology of this interesting and unusual clinical symptom is unknown but probably involves disinhibition and release of the so-called coordination center located in the upper brainstem due to compression by the tumor.

In this study, a novel computational solution integrating chemical-induced genomic residual effect prediction with in vitro-based risk assessment is proposed to obtain the cumulative health risk of typical chemical mixtures of particulate matters (PM).

Accuracy of IP-10 for diagnosing latent tuberculosis infection: a systematic review and meta-analysis.

Clin Microbiol Infect 2018 Dec 13. Epub 2018 Dec 13.

Department of Pediatrics, West China Second University Hospital, Sichuan University, Chengdu, China; Key Laboratory of Obstetric & Gynecologic and Pediatric Diseases and Birth Defects of Ministry of Education, Sichuan University, Chengdu, China. Electronic address:

Background: Effective diagnostic methods for detecting latent tuberculosis infection (LTBI) are important for its eradication. A number of studies have evaluated the use of interferon gamma-induced protein 10 (IP-10), which is elevated after tuberculosis infection, as a biomarker for LTBI, but conclusive results regarding its effectiveness have not been reported.

Objectives: Our objective was to assess the diagnostic value of IP-10 for LTBI. Read More

Corneal-PAMPA: A novel, non-cell-based assay for prediction of corneal drug permeability.

Eur J Pharm Sci 2018 Dec 13. Epub 2018 Dec 13.

Chemistry Department, Gedeon Richter Plc, Gyömrői út 19-21, 1107 Budapest, Hungary. Electronic address:

The present study was aimed to develop an in vitro non-cell-based method, for the measurement of corneal permeability. To this avail, the parallel artificial membrane permeability assay (PAMPA) was used for studying the effects of composition of the artificial lipid membrane, the DMSO cosolvent content of the donor phase as well as different buffer solutions in the model. Based on experimental corneal permeability values of 25 active pharmaceutical ingredients (APIs), a final model with good predictive ability (R = 0. Read More

Risk factors for admission after shoulder arthroscopy.

J Shoulder Elbow Surg 2018 Dec 13. Epub 2018 Dec 13.

Department of Orthopaedic Surgery, Feinberg School of Medicine, Northwestern University, Chicago, IL, USA.

Background: Shoulder arthroscopy is a common orthopedic procedure typically performed on an outpatient basis. Occasionally, patients require an unplanned hospital admission. An understanding of the incidence and risk factors for admission after shoulder arthroscopy may assist surgeons in determining which patients may be susceptible to unplanned admission after surgery.

Efficacy and safety of lipoprotein apheresis in children with homozygous familial hypercholesterolemia: A systematic review.

J Clin Lipidol 2018 Nov 3. Epub 2018 Nov 3.

Department of Paediatric Medicine, Amsterdam UMC, University of Amsterdam, the Netherlands.

Background: Homozygous familial hypercholesterolemia (HoFH) is a rare genetic disorder that may cause life-threatening cardiovascular disease (CVD) at childhood. Marginal effectiveness of statins in reducing low-density lipoprotein cholesterol (LDL-C) is the reason why extracorporeal removal of LDL-C by lipoprotein apheresis (LA) is recommended at the earliest possible age.

Objective: It is, however, unknown to what extent LA effectively reduces the burden of CVD in children with HoFH. Read More

Maini's Many Contributions to Mathematical Enzyme Kinetics: A Review.

J Theor Biol 2018 Dec 13. Epub 2018 Dec 13.

Department of Mathematics, Kennesaw State University, 370 Paulding Ave. NW Kennesaw. GA 30144, UK.

Modelling enzyme kinetics has a long history, as one of the earliest areas where mathematics was utilized to understand biological (in this case, biochemical) phenomena. By using differential equations and the law of mass action, many researchers have discovered information about the mechanisms of enzyme workings in the more than 100 years since Leonor Michaelis and Maud Menten published their classic paper in 1913. This work uses the laws obeyed by molecules during a reaction, translates them into mathematical equations, and then compares the results predicted by the equations to data obtained in laboratory conditions.
