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

The epidemiology of reverse transmission of COVID-19 in Gansu Province, China.

Travel Med Infect Dis 2020 Sep-Oct;37:101741. Epub 2020 May 12.

School of Public Health, Gansu University of Chinese Medicine, No. 35 Dingxi East Road, Lanzhou, 730000, Gansu Province, China; Discipline of Pathology, School of Medical Sciences and Bosch Institute, Charles Perkins Centre, The University of Sydney, NSW, 2006, Sydney, Australia. Electronic address:

Background: The transmission of COVID-19 is about to come under control within China, however, an emerging challenge to the Chinese authorities is reverse transmission due to COVID-19 patients/carriers evacuating from overseas to China.

Methods: We analysed the epidemiological characteristics of 311 Chinese citizens evacuated from Iran. All confirmed COVID-19 cases amongst the returnees were displayed by the spatial distribution pattern of the extent of COVID-19 infection. Read More

A quantitative assessment of atmospheric emissions and spatial distribution of trace elements from natural sources in China.

Environ Pollut 2020 Apr 8;259:113918. Epub 2020 Jan 8.

State Key Joint Laboratory of Environmental Simulation & Pollution Control, School of Environment, Beijing Normal University, Beijing, 100875, China; Center for Atmospheric Environmental Studies, Beijing Normal University, Beijing, 100875, China.

Natural sources, such as soil and wind-erosion dust (SWD), biomass open burning (BOB), sea salt spray (SSAS) and biogenic source (BIO), are major contributors to atmospheric emissions of trace elements (TEs) globally. In this study, we used a comprehensive approach to account for area-, production- and biofuel consumption-based emission factor calculation methods, and thus developed an integrated high-resolution emission inventory for 15 types of TEs (As, B, Cd, Co, Cr, Cu, Hg, Mn, Mo, Ni, Pb, Sb, Se, V and Zn) originated from natural sources in China for the year 2015. The results show that national emissions of TEs in 2015 range from 7. Read More

Influence of river discharge on abundance and composition of phytoplankton in the western coastal Bay of Bengal during peak discharge period.

Mar Pollut Bull 2018 Aug 19;133:671-683. Epub 2018 Jun 19.

National Institute of Oceanography, Council of Scientific and Industrial Research, Regional Centre, 176 Lawsons Bay Colony, Visakhapatnam, India; National Centre for Antarctic and Ocean Research (NCAOR), MoES, Government of India.

To understand the influence of river discharge on phytoplankton composition along western coastal Bay of Bengal (BoB), surface water samples were collected during peak discharge period. River discharge from the Ganges influences northwest (NW) coastal BoB whereas peninsular rivers (Godavari and Krishna) discharge to the southwest (SW) coastal Bay. River discharge from the Ganges is an order of magnitude higher than peninsular river resulting in low saline, less suspended matter and lower nutrients concentrations in the NW and contrasting to that was observed in the SW.

Pain and compression neuropathy in primary inguinal hernia.

Hernia 2017 10 17;21(5):715-722. Epub 2017 Aug 17.

University of Denver, Denver, USA.

Purpose: Enlargement of the ilioinguinal nerve at the external inguinal ring is observed in 34% of patients undergoing primary open inguinal herniorrhaphy; in 88% of patients it occurs at the fascial edge where the hernia mushrooms with abdominal pressure. Compression neuropathy occurs near many anatomical nerve constriction sites and is associated with enlargement of the peripheral nerve accompanied by sensory changes.

Methods: In this prospective study, Carolina Comfort Scale (CCS) questionnaire data was collected for 35 primary hernia repairs. Read More

Why do inguinal hernia patients have pain? Histology points to compression neuropathy.

Am J Surg 2017 May 22;213(5):975-982. Epub 2017 Mar 22.

University of Denver, Denver, CO USA. Electronic address:

Purpose: The purpose of this study is to describe the known soft tissue neuro-histology factors associated with compression neuropathy in relation to the incidence of preoperative pain in primary inguinal hernia. Enlargement of the ilioinguinal nerve occurs in 63% of patients with primary inguinal hernia; compression neuropathy has similar gross features.

Methods: Patients completed pain questionnaires pertaining to preoperative pain and the quality of pain experienced. Read More

Assessment of genetic diversity among barley cultivars and breeding lines adapted to the US Pacific Northwest, and its implications in breeding barley for imidazolinone-resistance.

PLoS One 2014 26;9(6):e100998. Epub 2014 Jun 26.

Department of Crop & Soil Sciences, Washington State University, Pullman, Washington, United States of America; School of Molecular Biosciences, Washington State University, Pullman, Washington, United States of America; Centre for Reproductive Biology, Washington State University, Pullman, Washington, United States of America.

Extensive application of imidazolinone (IMI) herbicides had a significant impact on barley productivity contributing to a continuous decline in its acreage over the last two decades. A possible solution to this problem is to transfer IMI-resistance from a recently characterized mutation in the 'Bob' barley AHAS (acetohydroxy acid synthase) gene to other food, feed and malting barley cultivars. We focused our efforts on transferring IMI-resistance to barley varieties adapted to the US Pacific Northwest (PNW), since it comprises ∼23% (335,000 ha) of the US agricultural land under barley production.

New method for evaluating irreversible adsorption and stationary phase bleed in gas chromatographic capillary columns.

J Chromatogr A 2012 Oct 13;1261:142-50. Epub 2012 Jun 13.

Pacific Northwest National Laboratory, Richland, WA 99352, USA.

A novel method is described for the evaluation of irreversible adsorption and column bleed in gas chromatographic (GC) columns using a tandem GC approach. This work specifically determined the degree of irreversible adsorption behavior of specific sulfur and phosphorous containing test probe compounds at levels ranging from approximately 50 picograms (pg) to 1 nanogram (ng) on selected gas chromatographic columns. This method does not replace existing evaluation methods that characterize reversible adsorption but provides an additional tool. Read More

Estimating vertebrate, benthic macroinvertebrate, and diatom taxa richness in raftable Pacific Northwest rivers for bioassessment purposes.

Environ Monit Assess 2012 May 29;184(5):3185-98. Epub 2011 Jun 29.

Department of Fisheries and Wildlife, Oregon State University, Corvallis, OR 97333, USA.

The number of sites sampled must be considered when determining the effort necessary for adequately assessing taxa richness in an ecosystem for bioassessment purposes; however, there have been few studies concerning the number of sites necessary for bioassessment of large rivers. We evaluated the effect of sample size (i.e. Read More

Using Biowin, Bayes, and batteries to predict ready biodegradability.

Environ Toxicol Chem 2004 Apr;23(4):911-20

US Environmental Protection Agency, Office of Pollution Prevention and Toxics, 1200 Pennsylvania Avenue, Northwest, Washington, DC 20460, USA.

Whether or not a given chemical substance is readily biodegradable is an important piece of information in risk screening for both new and existing chemicals. Despite the relatively low cost of Organization for Economic Cooperation and Development tests, data are often unavailable and biodegradability must be estimated. In this paper, we focus on the predictive value of selected Biowin models and model batteries using Bayesian analysis. Read More
