A combination of metabolic modifications by light stimulus and photodynamic action is very attractive. Photobiomodulation therapy (PBMT) comprehends a vast range of applications and has been shown to be suitable to ease morbidities caused by chemotherapy and radiation, such as mucositis and dermatitis. The current study investigates the effects of near-infrared PBMT combined with porphyrin-based photodynamic therapy (PDT) in squamous cell carcinoma cell lines SCC-25 and SCC-4. The aim is to evaluate the potential of this combination to improve PDT outcome by increasing cell toxicity. Many techniques were used to verify the combined effect. Photobiomodulation (PBM) enhanced PDT action in SCC-25 cells by increasing photosensitizer (PS) uptake and production of reactive oxygen species (ROS). The equivalent was not seen in SCC-4 cells compared to the PDT only group. We believe these effects are strongly related to the interval of application between PBMT, PS incubation and PDT. Additionally, the effect of ascorbic acid on preventing PBM effects in PDT shows that ROS play an important role in the early mechanisms of PBM-PDT. Therefore, we believe PBM-PDT combination is worth exploring, for its benefit-cost ratio and simple protocols, along with the possibility of improvement in treatment resuts.
Although epidemiological studies on the effect of chronic fine particulate matter (PM
) exposure on lipid disorders have been conducted, it is unclear if improved air quality is associated with beneficial changes in the blood lipid profile. In China, clean air actions introduced in 2013 have rapidly reduced the concentration of ambient PM
.

We conducted a change-by-change study, based on two waves (2011 and 2015) of a national survey of the same 5111 Chinese adults before and after implementation of the clean air actions. Long-term PM
exposure was assessed using a state-of-the-art estimator at the city level. Based on the within-individual differences between the two waves, we associated PM
changes with the variations of four lipid biomarkers-triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C)-using a mixed-effects regression model. The robustness and homogeneity of the association were tested via sensitivity analycing LDL-C and TC levels. Clean air policies should be implemented as public health measures in countries with aging societies, especially developing ones with a high air pollution burden.
The prevalence of obstructive sleep apnea (OSA) among professional truck drivers has varied from 28 to 78% in previous studies. In this study we wanted to estimate the prevalence of OSA and OSA with both subjectively measured sleepiness and objectively measured ability to stay awake (ie obstructive sleep apnea syndrome, OSAS) among professional truck drivers in Finland.

Altogether 2066 professional truck drivers received a structured questionnaire. 175 drivers had a clinical examination and sleep laboratory studies, which included respiratory polygraphy (RP) and maintenance of wakefulness test (MWT). Three groups were formed 75 subjects with suspected sleep apnea, 75 healthy controls and a random sample of 25 subjects.

1095 drivers answered the questionnaire. RP was performed on 172 drivers and 167 drivers participated in MWT. The mean age was 40.7 years and the mean BMI was 27.7kgm
. The prevalence of sleep apnea in professional truck drivers using various criteria were AHI ≥5 40.1%, AHI≥ 15 16.2% and, AHI≥ 30 7.2%. The prevalence depended on clinical history. Prevalence of AHI≥5 varied between 20 and 56.9% and prevalence of AHI≥15 was 4.3-25%. selleck inhibitor Altogether 4.8% of subjects with AHI ≥15 had abnormally short sleep latency in MWT (<19.4min).

Moderate sleep apnea is common among professional truck drivers but significant inability to stay awake, defined as MWT <19.4min, is found in about one of twenty professional drivers.

This study examined changes due to COVID-19 lockdown in young and older adults' self-reported sleep quality and dysfunctional sleep-related beliefs.

Adults involved in studies prior to the pandemic were contacted during the COVID-19 lockdown. Seventeen young adults (age range 18-35 years) and 21 older adults (age range 65-90 years) agreed to participate. Participants were interviewed by phone (between 27th April and 4
May, 2020) to complete the Pittsburgh Sleep Quality Index (PSQI) and the Dysfunctional Beliefs About Sleep (DBAS) questionnaire they had been administered before the pandemic.

In terms of mean changes, the results showed null effect sizes for changes in self-reported sleep quality for both age groups. In young adults, a medium effect size emerged for changes in sleep latency, which increased during lockdown. No changes in any of the self-reported sleep quality dimensions emerged in older adults. In both age groups, the effect sizes for changes in dysfunctional sleep-related beliefs were negligible. In older adults, however, changes in self-reported sleep quality were largely associated with changes in dysfunctional sleep-related beliefs.

Our results suggest that self-reported sleep quality and dysfunctional sleep-related beliefs were not affected by the COVID-19 lockdown in young or older adults. They also suggest that it might be useful to consider changes in dysfunctional sleep-related beliefs to better capture the impact of stressful events (such as a period of quarantine) on sleep quality, especially where older adults are concerned.
