Decadal variations in natural and anthropogenic aerosol optical depth over the Bay of Bengal: the influence of pollutants from Indo-GangeticPlain.

Environ Sci Pollut Res Int 2021 Jun 15. Epub 2021 Jun 15.

CSIR-National Institute of Oceanography, 176 Lawsons Bay Colony, Visakhapatnam, 530017, India.

Perennial increase in atmospheric pollution over the Bay of Bengal (BoB) and South China Sea is reported due to increase in human population and industrial activity in South and Southeast Asia. Based on total aerosol optical depth (AOD) derived from MODIS (moderate resolution imaging resolution imaging spectroradiometer), natural and anthropogenic fractions were derived. The seasonality and spatial variability in rate of increase in total, natural, and anthropogenic AOD fractions were examined over the BoB using data collected between 2001 and 2019. Read More

[C]PIB amyloid quantification: effect of reference region selection.

EJNMMI Res 2020 Oct 19;10(1):123. Epub 2020 Oct 19.

Department of Radiology and Nuclear Medicine, Amsterdam Neuroscience, Amsterdam UMC, Vrije Universiteit Amsterdam, De Boelelaan 1117, 1081 HV, Amsterdam, The Netherlands.

Background: The standard reference region (RR) for amyloid-beta (Aβ) PET studies is the cerebellar grey matter (GMCB), while alternative RRs have mostly been utilized without prior validation against the gold standard. This study compared five commonly used RRs to gold standard plasma input-based quantification using the GMCB.

Methods: Thirteen subjects from a test-retest (TRT) study and 30 from a longitudinal study were retrospectively included (total: 17 Alzheimer's disease, 13 mild cognitive impairment, 13 controls). Read More

Modulating the Properties of Metal-Sensing Whole-Cell Bioreporters by Interfering with Metal Homeostasis.

J Microbiol Biotechnol 2018 Feb;28(2):323-329

Department of Forest Resources, Gyeongnam National University of Science and Technology, Jinju 52725, Republic of Korea.

In , the transcription of genes related to metal homeostasis is activated by the presence of target metals. The promoter regions of those genes can be fused with reporter genes to generate whole-cell bioreporters (WCBs); these organisms sense the presence of target metals through reporter gene expression. However, the limited number of available promoters for sensing domains restricts the number of WCB targets. Read More

Simultaneous detection of bioavailable arsenic and cadmium in contaminated soils using dual-sensing bioreporters.

Appl Microbiol Biotechnol 2016 Apr 6;100(8):3713-22. Epub 2016 Feb 6.

Department of Environmental Health Science, Konkuk University, Seoul, 05029, South Korea.

Whole-cell bioreporters (WCBs) have attracted increasing attention during the last few decades because they allow fast determination of bioavailable heavy metals in contaminated sites. Various WCBs to monitor specific heavy metals such as arsenic and cadmium in diverse environmental systems are available. However, currently, no study on simultaneous analysis of arsenic and cadmium has been reported, even though soils are contaminated by diverse heavy metals and metalloids. Read More

Progressive Myelopathy Patients Who Lack Spinal Cord Monitoring Data Have the Highest Rate of Spinal Cord Deficits Following Posterior Vertebral Column Resection Surgery.

Spine Deform 2015 Jul 11;3(4):352-359. Epub 2015 Jun 11.

Department of Orthopaedic Surgery, Washington University School of Medicine, 660 S. Euclid Avenue, Campus Box 8233, St. Louis, MO 63110, USA.

Objectives: The authors analyzed patients who underwent posterior vertebral column resection (PVCR). All patients had spinal cord monitoring (SCM) attempted but some did not have predictable and usable tracings.

Summary Of Background Data: Posterior vertebral column resection is a powerful technique to correct severe spinal deformities but it has the potential for major neurologic complications. Read More

Effect of summer outdoor temperatures on work-related injuries in Quebec (Canada).

Occup Environ Med 2015 May 24;72(5):338-45. Epub 2015 Jan 24.

Department of Environmental and Occupational Health, School of Public Health, Université de Montréal, Montréal, Québec, Canada Institut de recherche Robert-Sauvé en santé et sécurité du travail (IRSST), Montréal, Québec, Canada.

Objective: To quantify the associations between occupational injury compensations and exposure to summer outdoor temperatures in Quebec (Canada).

Methods: The relationship between 374,078 injuries compensated by the Workers' Compensation Board (WCB) (between May and September, 2003-2010) and maximum daily outdoor temperatures was modelled using generalised linear models with negative binomial distributions. Pooled effect sizes for all 16 health regions of Quebec were estimated with random-effect models for meta-analyses for all compensations and by sex, age group, mechanism of injury, industrial sector and occupations (manual vs other) within each sector.

Functional GFP-metallothionein fusion protein from Tetrahymena thermophila: a potential whole-cell biosensor for monitoring heavy metal pollution and a cell model to study metallothionein overproduction effects.

Biometals 2014 Feb 16;27(1):195-205. Epub 2014 Jan 16.

Departamento de Microbiología-III, Facultad de Biología, Universidad Complutense (UCM), C/. José Antonio Novais 12, 28040, Madrid, Spain.

The significance of metal(oid)s as environmental pollutants has made them a priority in ecotoxicology, with the aim of minimizing exposure to animals or humans. Therefore, it is necessary to develop sensitive and inexpensive methods that can efficiently detect and monitor these pollutants in the environment. Conventional analytical techniques suffer from the disadvantages of high cost and complexity. Read More

Strategies of survival and resource exploitation in the Antarctic fellfield ecosystem.

Biol Rev Camb Philos Soc 2009 Aug;84(3):449-84

Biological Sciences Division, British Antarctic Survey, Natural Environment Research Council, High Cross, Madingley Road, Cambridge, CB3 OET, UK.

Antarctic fellfields present organisms with a heterogeneous habitat characterised by a wide variety of environmental stresses. These include low temperatures, limited moisture availability, frequent and often rapid freeze-thaw and hydration-dehydration cycles, exposure to high photosynthetic photon flux density and ultraviolet (uv) irradiance, seasonal snow cover, high winds, cryoturbation and, depending on location south of the Antarctic Circle, considerable daylight in summer. Most of these factors vary both predictably and unpredictably in spatial and temporal planes. Read More
