Menthol cigarettes, tobacco dependence, and smoking persistence: The need to examine enhanced cognitive functioning as a neuropsychological mechanism.

Nicotine Tob Res 2018 Dec 14. Epub 2018 Dec 14.

Department of Preventive Medicine, Northwestern University Feinberg School of Medicine, Chicago, Illinois, USA.

Introduction: Despite the overall decline in the prevalence of cigarette use in the United States, menthol cigarette use among smokers is rising, and evidence shows that it may lead to more detrimental effects on public health than regular cigarette use. One of the mechanisms by which nicotine sustains tobacco use and dependence is due to its cognitive enhancing properties, and basic science literature suggests that menthol may also enhance nicotine's acute effect on cognition.

Aims And Methods: The purpose of this review is to suggest that the cognitive enhancing effects of menthol may be a potentially important neuropsychological mechanism that has yet to be examined. Read More

Environ Pollut 2018 Dec 5;246:198-206. Epub 2018 Dec 5.

Institute of Applied Geosciences, Technical University of Darmstadt, Schnittspahnstrasse 9, 64287, Darmstadt, Germany; IWW Water Centre, Moritzstrasse 26, 45476, Mülheim an der Ruhr, Germany. Electronic address:

In the present work, we analyzed the concentration patterns of 20 Polycyclic Aromatic Hydrocarbons (PAHs) in 25 surface sediments and 11 sediment cores from the northern part of Taihu Lake, China. Three of the cores were dated based on Cs activity for the deposition age of the sediment. The spatial distributions of the PAH concentrations show that the inflow rivers into Zhushan Bay and Meiliang Bay were the main pathway for PAHs and sediment input to the northern part of the lake.

Odorous compounds sources and transport from a swine deep-pit finishing operation: A case study.

J Environ Manage 2018 Dec 11;233:12-23. Epub 2018 Dec 11.

USDA Agricultural Research Service, National Laboratory for Agriculture and the Environment, 1015 N. University Boulevard, Ames, IA, 50011, United States.

Odor emissions from swine finishing operations are an air quality issue that affects residents at the local level. A study was conducted at a commercial swine deep-pit finishing operation in central Iowa to monitor odorous compounds emitted and transported offsite. Gaseous compounds were sampled using either sorbent tubes or canisters with GC/MS analysis, and particulates matter (PM) were sampled with high volume samplers and thermally extracted onto sorbent tubes for GC/MS analysis.

Can catchment-scale urban stormwater management measures benefit the stream hydraulic environment?

J Environ Manage 2018 Dec 11;233:1-11. Epub 2018 Dec 11.

Waterway Ecosystem Research Group, School of Ecosystem and Forest Science, The University of Melbourne, Burnley, Victoria, 3121, Australia.

The potential for catchment-scale stormwater control measures (SCMs) to mitigate the impact of stormwater runoff issues and excess stormwater volume is increasingly recognised. There is, however, limited understanding about their potential in reducing in-channel disturbance and improving hydraulic conditions for stream ecosystem benefits. This study investigates the benefits that SCM application in a catchment have on in-stream hydraulics. Read More

Pre-harvest internalization and surface survival of Salmonella and Escherichia coli O157:H7 sprayed onto different lettuce cultivars under field and growth chamber conditions.

Int J Food Microbiol 2018 Dec 4;291:197-204. Epub 2018 Dec 4.

Department of Horticulture, University of Georgia, 2360 Rainwater Rd., Tifton, GA 31793-5766, USA.

Plant genotype has been advocated to have an important role in the fate of enteric pathogens residing in lettuce foliage. This study was therefore undertaken under the premise that different pathogen responses could occur in lettuce cultivars with cultivar selection being one of several hurdles in an overall strategy for controlling foodborne pathogens on field-grown produce. Up to eight lettuce cultivars ('Gabriella', 'Green Star', 'Muir', 'New Red Fire', 'Coastal Star', 'Starfighter', 'Tropicana', and 'Two Star') were examined in these experiments in which the plants were subjected to spray contamination of their foliage with pathogens.

Prolonging food shelf-life by dual actives release from multi-layered polymer particles.

Colloids Surf B Biointerfaces 2018 Dec 4;175:281-290. Epub 2018 Dec 4.

Department of Materials Science and Engineering, Indian Institute of Technology, Delhi, 110016, India. Electronic address:

Biodegradable polymer based 'controlled release packaging' technology has ability to release packaging actives in controlled manner to prolong the food shelf-life. Currently available systems are not sufficiently capable of releasing multiple actives in sustainable fashion. Hence, the purpose of this study was to develop dual actives (antioxidant and antibacterial) loaded multilayered microparticles in one step and to release them at rates suitable for long-term inhibition of bacterial growth as well as lipid oxidation in food.
