Research review (peer-reviewed)abstract
- Although the world is shifting toward using more renewable energy resources, combustion systems will still play an important role in the immediate future of global energy. To follow a sustainable path to the future and reduce global warming impacts, it is important to improve the efficiency and performance of combustion processes and minimize their emissions. Machine learning techniques are a cost-effective solution for improving the sustainability of combustion systems through modeling, prediction, forecasting, optimization, fault detection, and control of processes. The objective of this study is to provide a review and discussion regarding the current state of research on the applications of machine learning techniques in different combustion processes related to power generation. Depending on the type of combustion process, the applications of machine learning techniques are categorized into three main groups: (1) coal and natural gas power plants, (2) biomass combustion, and (3) carbon capture systems. This study discusses the potential benefits and challenges of machine learning in the combustion area and provides some research directions for future studies. Overall, the conducted review demonstrates that machine learning techniques can play a substantial role to shift combustion systems towards lower emission processes with improved operational flexibility and reduced operating cost.

Journal article (peer-reviewed)abstract
- Serum levels of relaxin in 25 women with premenstrual dysphoria and 25 age-matched controls were determined at three time points during the menstrual cycle. At the same time, levels of estradiol, progesterone, 17-beta-OH-progesterone, free testosterone, total testosterone, sex hormone binding hormone, androstenedione, dehydroepiandrosterone sulphate, and 3-alpha-androstanediol glucuronide were determined. Detectable levels of relaxin were found in all women in both the follicular and luteal phase as well as around ovulation, the inter-individual variations being larger than intra-individual differences. The levels of relaxin were not influenced by the fluctuation of the other reproductive hormones. A significant difference between the two groups of women was observed, subjects with premenstrual dysphoria displaying reduced levels of relaxin (p < 0.05) compared to controls. Also, when analysed with respect to a variable number of tandem repeats polymorphism (CT repeats followed by GT repeats) in the promotor region of the relaxin H2 gene, women with premenstrual dysphoria (n = 29) were found to display significantly longer GT repeats than controls (n = 35).

THE EFFECT OF 3 DIFFERENT EXERCISE APPROACHES ON NECK MUSCLE ENDURANCE, KINESIOPHOBIA, EXERCISE COMPLIANCE, AND PATIENT SATISFACTION IN CHRONIC WHIPLASH
- 2015
-
In: Journal of Manipulative and Physiological Therapeutics. - : MOSBY-ELSEVIER. - 0161-4754 .- 1532-6586. ; 38:7, s. 465-746.e4

Journal article (peer-reviewed)abstract
- Objective: The purpose of this study was to compare the effects of 3 different exercise approaches on neck muscle endurance (NME), kinesiophobia, exercise compliance, and patient satisfaction in patients with chronic whiplash. Methods: This prospective randomized clinical trial included 216 individuals with chronic whiplash. Participants were randomized to 1 of 3 exercise interventions: neck-specific exercise (NSE), NSE combined with a behavioral approach (NSEB), or prescribed physical activity (PPA). Measures of ventral and dorsal NME (endurance time in seconds), perceived pain after NME testing, kinesiophobia, exercise compliance, and patient satisfaction were recorded at baseline and at the 3- and 6-month follow-ups. Results: Compared with individuals in the prescribed physical activity group, participants in the NSE and NSEB groups exhibited greater gains in dorsal NME (P = .003), greater reductions in pain after NME testing (P = .03), and more satisfaction with treatment (P less than .001). Kinesiophobia and exercise compliance did not significantly differ between groups (P greater than .07). Conclusion: Among patients with chronic whiplash, a neck-specific exercise intervention (with or without a behavioral approach) appears to improve NME. Participants were more satisfied with intervention including neck-specific exercises than with the prescription of general exercise.

The Immune Functions of Keratinocytes in Skin Wound Healing
- 2020

In: International journal of molecular sciences. - : MDPI AG. - 1422-0067. ; 21:22

Journal article (peer-reviewed)abstract
- As the most dominant cell type in the skin, keratinocytes play critical roles in wound repair not only as structural cells but also exerting important immune functions. This review focuses on the communications between keratinocytes and immune cells in wound healing, which are mediated by various cytokines, chemokines, and extracellular vesicles. Keratinocytes can also directly interact with T cells via antigen presentation. Moreover, keratinocytes produce antimicrobial peptides that can directly kill the invading pathogens and contribute to wound repair in many aspects. We also reviewed the epigenetic mechanisms known to regulate keratinocyte immune functions, including histone modifications, non-protein-coding RNAs (e.g., microRNAs, and long noncoding RNAs), and chromatin dynamics. Lastly, we summarized the current evidence on the dysregulated immune functions of keratinocytes in chronic nonhealing wounds. Based on their crucial immune functions in skin wound healing, we propose that keratinocytes significantly contribute to the pathogenesis of chronic wound inflammation. We hope this review will trigger an interest in investigating the immune roles of keratinocytes in chronic wound pathology, which may open up new avenues for developing innovative wound treatments.
