Assessment of tobacco heating product THP1.0. Part 4: Characterisation of indoor air quality and odour

Publication date: March 2018 Source:Regulatory Toxicology and Pharmacology, Volume 93 Author(s): Mark Forster, John McAughey, Krishna Prasad, Eleni Mavropoulou, Christopher Proctor The tobacco heating product THP1.0, which heats but does not burn tobacco, was tested as part of a modified-risk tobacco product assessment framework for its impacts on indoor air quality and residual tobacco smoke odour. THP1.0 heats the tobacco to less than 240 °C ± 5 °C during puffs. An environmentally controlled room was used to simulate ventilation conditions corresponding to residential, office and hospitality environments. An analysis of known tobacco smoke constituents, included CO, CO2, NO, NO2, nicotine, glycerol, 3-ethenyl pyridine, sixteen polycyclic aromatic hydrocarbons, eight volatile organic compounds, four carbonyls, four tobacco-specific nitrosamines and total aerosol particulate matter. Significant emissions reductions in comparison to conventional cigarettes were measured for THP1.0. Levels of nicotine, acetaldehyde, formaldehyde and particulate matter emitted from THP1.0 exceeded ambient air measurements, but were more than 90% reduced relative to cigarette smoke emissions within the laboratory conditions defined Residual tobacco smoke odour was assessed by trained sensory panels after exposure of cloth, hair and skin to both mainstream and environmental emissions from the test products. Residual tobacco smoke odour was significantly lower from THP1.0 ...

Publication date: September 2018 Source:Protein Expression and Purification, Volume 149 Author(s): Shijie Li, Linlin Li, Zhuo Chen, Guangpu Xue, Longguang Jiang, Ke Zheng, Jincan Chen, Rui Li, Cai Yuan, Mingdong Huang Plasma-derived human serum albumin (pHSA) has important applications in many clinical indications, including blood loss, serious burn, or hemorrhagic shock. The limited supply and potential infectious pathogen contamination of pHSA have stimulated the development of recombinant human serum albumin (rHSA). However, rHSA often entraps endogenous or exogenous impurities, including color pigments and polysacchar...

Dear Carol: My Dad cared for Mom for seven years until she died from Alzheimer’s. Now, Dad needs a little help. He knows how hard caregiving can be, and with my working full time, he's worried that I’ll burn out or get sick if I take on his care. He has money to pay for some hired help at home which is where he wants to stay. He has a personal alarm and is safety conscious. I live with depression, though I’m treated. Still, I have kids at home so I do have limits in what I can do for Dad. When I read about caregiver burnout I worry about that happening to me. I don’t want to get so that I hate ...

“Put me out of my misery!” I’ve pleaded to anyone within earshot in the throes of a grueling day, a rant from one feeling burnt out. There are days I want to pull my hair out, even the ones that aren’t gray. One night I caught myself grunting, “I hate my life,” while heading out the door at 12 a.m., after an already exhausting day in the OR. No sane person should ever say that. But the world of medicine nowadays is far from sane. After returning home for two hours of sleep, I drag myself to the office with a full patient-load, which is not bad in itself if it weren’t for that unset...

Conclusions These results demonstrate significantly shorter cSP in the burned arm in patients with upper limb burn sustained <2years ago, those with partial thickness burns, those with upper limb burns only, and those with burns of less than 10% TBSA. The results are consistent with the existing literature, which demonstrates a reduction in cSP duration in patients with a range of peripheral nerve injuries. There is a strong suggestion that cortical inhibition is altered following burn injury, and that TMS is a useful and sensitive method for investigating changes in cortical inhibition in burn patients.

Conclusions Based on the data from our unit, sustaining a burn as an elderly person does not reduce life expectancy. Medical and surgical complications, immediate, early and late, although higher with greater frailty and TBSA of burn, but do not adversely affect survival in this population.

Conclusion Taken together, SOE noticeably inhibited replication and antigen secretion of HBV, which was at least in part attributed to ziyuglycoside II, thus presenting the possibility of developing therapeutic candidates for the treatment of HBV-related diseases.

Labouring in water may reduce the number of women having an epidural but does not appear to affect mode of birth or serious perineal tears.Water immersion during labour and birth is increasingly popular and is becoming widely accepted across many countries, and particularly in midwifery-led care settings. However, there are concerns around neonatal water inhalation, increased requirement for admission to neonatal intensive care unit (NICU), maternal and/or neonatal infection, and obstetric anal sphincter injuries (OASIS).A team of Cochrane authors based in the United Kingdom worked withCochrane Pregnancy and Childbirth to ...
