In this review, we summarise the present state of knowledge on the anaerobic biodegradation process for phenol, a typical target compound employed in toxicity studies on industrial wastewater treatment. The objective of this article is to provide an overview on the microbiological and technological aspects of anaerobic phenol degradation and on the research needs to fill the gaps still hindering the diffusion of the anaerobic process. The first part is focused on the microbiology and extensively presents and characterises phenol-degrading bacteria and biodegradation pathways. In the second part, dedicated to process feasibility, anaerobic and aerobic biodegradation kinetics are analysed and compared, and strategies to enhance process performance, i.e. advanced technologies, bioaugmentation, and biostimulation, are critically analysed and discussed. The final section provides a summary of the research needs. Literature data analysis shows the feasibility of anaerobic phenol biodegradation at laboratory and pilot scale, but there is still a consistent gap between achieved aerobic and anaerobic performance. This is why current research demand is mainly related to the development and optimisation of powerful technologies and effective operation strategies able to enhance the competitiveness of the anaerobic process. Research efforts are strongly justified because the anaerobic process is a step forward to a more sustainable approach in wastewater treatment.Key points• Review of phenol-degraders bacteria and biodegradation pathways.• Anaerobic phenol biodegradation kinetics for metabolic and co-metabolic processes.• Microbial and technological strategies to enhance process performance.Alkyl hydroperoxide reductase (AhP), catalase G (KatG), and catalase E (KatE) are the main enzymes to scavenge the excessive hydrogen peroxide in E. coli. It was found the concentration of endogenous H2O2 was submicromolar in a mutant strain E. coli MG1655/ΔAhpΔKatEΔKatG, which was enough to cause damage to DNA and proteins as well as concomitant cell growth and metabolism. However, few studies explored how submicromolar intracellular hydrogen peroxide alters protein function and regulates the signaling pathways at the proteome level. In order to study the effect of endogenous oxidative stress caused by submicromolar hydrogen peroxide, this study first constructed a mutant strain E. coli MG1655/ΔAhpΔKatEΔKatG. Then, label-free quantitative proteomic analysis was used to quantify the differentially expressed proteins between the wild-type strain and the mutant strain. A total of 265 proteins were observed as differentially expressed proteins including 108 upregulated proteins and 157 downregulated proteins. Amxpressed proteins were quantified and enriched in metabolic pathways and antioxidant systems by using label-free proteomics analysis. • The findings of this study demonstrate that the mutant E. coli may serve as an effective tool to investigate the endogenous oxidative stress.
The aim of excimer laser-assisted deep anterior lamellar keratoplasty (excimer-DALK) is, as in mechanical DALK, the treatment of keratectasia (keratoconus and pellucid marginal degeneration), stromal scars or stromal corneal dystrophy. A prerequisite for surgery is the absence of (pre‑) Descemet's scars and an intact endothelium.

After excimer laser-assisted trephination to 80% of the corneal thickness at the trephination site, intrastromal air injection (so-called big bubble) and lamellar corneal preparation, alamellar anterior transplantation of the endothelium-free donor tissue is performed. The technique combines the advantages of DALK and excimer laser trephination. We describe the steps of an excimer-DALK from the Homburg Keratoconus Center (HKC).

Excimer-DALK is aviable treatment option for patients with intact endothelium. In cases of intraoperative perforation, conversion to excimer-perforating keratoplasty (PKP) with all the advantages of excimer laser trephination remains feasible.

Store-and-forward teledermatology is a simple and effective approach which enables remote dermatological diagnosis and treatment. Implementing store-and-forward technology in rural Mississippi has the potential to expand access to dermatology services at locations, where an in-person dermatologist is not available including emergency rooms, urgent care centers, and primary care practices. A survey study was conducted to assess perceived obstacles and attitudes about store-and-forward teledermatology among primary care providers in Mississippi's rural areas. WS6 modulator Most providers are very interested in the telehealth program and the opportunities it provides them to best treat their patients. Key barriers to engagement in teledermatology were (1) primary non-adherence this is rooted in misconception about teledermatology, the investment in time required to master the technology and establish digital links between primary care provider and consultant; and, (2) secondary non-adherence this is related to the time required to submit a teledermatology consult which disrupts busy offices. Emphasizing the benefits of teledermatology to primary care physicians and simplification of the teledermatology consult submission process may increase the use of teledermatology in rural Mississippi and serve as a model for other academic teledermatology programs throughout the United States.
This study retrospectively investigated the clinical utility of 2-deoxy-18F-fluorodeoxyglucose (
F-FDG) positron emission tomography/computed tomography (PET/CT) and circulating tumor cells (CTCs) in the diagnosis and prognosis of treatment-naive patients with non-small-cell lung cancer (NSCLC).

The blood samples of treatment-naive patients with NSCLC were collected for CTCs detection, and the tumor metabolic parameters of
F-FDG PET/CT, including maximum standard uptake value (SUVmax), metabolic tumor volume of primary lesion (MTV-P) and combination of primary lesion and metastases (MTV-C), and total lesion glycolysis of primary lesion (TLG-P) and combination of primary lesion and metastases (TLG-C), were analyzed. Age, sex, smoking, serum tumor markers, tumor size, location, TNM stage, and genetic mutations were also reviewed. link2 Moreover, progression-free survival (PFS) and overall survival (OS) of these patients were analyzed.

A total of 309 patients with NSCLC (200 men, 109 women; mean age 61 ± 9yea tumor glucose metabolism in NSCLC. Metabolic parameters of
F-FDG PET/CT and CTCs could separately predict the outcomes of treatment-naive patients with NSCLC.
18F-FDG PET/CT was superior to CTCs in the diagnosis of treatment-naive patients with NSCLC. link3 The levels of CTCs in the peripheral blood were associated with tumor glucose metabolism in NSCLC. Metabolic parameters of 18F-FDG PET/CT and CTCs could separately predict the outcomes of treatment-naive patients with NSCLC.

To evaluate whether GI symptoms and quality of life in patients with SSc demonstrate longitudinal stability. Consecutive patients with SSc (n = 100) completed the validated university of California at Los Angeles scleroderma clinical trial consortium gastrointestinal tract 2.0 (GIT) instrument and completed the same instrument approximately 5 years later. Comparison was made between patients with diffuse (dcSSc) and limited (lcSSc) subtypes and duration of disease of less than or greater than 5 years. GIT scores were calculated and analyzed for differences. 37 patients with dcSSc and 63 patients with lcSSc were included. Social functioning score significantly improved over time [0.44 (0.59)-0.31 (0.47); P = 0.003]. Total GIT scores were lower in patients with diffuse [0.51 (0.41)] compared with limited [(0.72 (0.53); P = 0.029] disease at both baseline and follow-up. Social functioning improved similarly in both dcSSc and lcSSc over time (P = 0.004). GIT Total scores increased in 27% (27/100) of patients and did not change or improved in 73% (73/100). Patients with worsening GI status had significantly increased scores on all GIT subscales. A lower body-mass index at baseline was significantly associated with worsening GIT Total score (OR 1.22; 95% CI 1.07-1.39; P  less then  0.001). Patients with SSc generally demonstrate longitudinal stability or improvement in their GI symptoms, but a subset of patients experience worsening of GI symptoms and negative impacts on GI-related quality of life.It has been proposed that motivating participants to perform well on a cognitive task ought to lead to decreases in rates of intentional, but not unintentional, task-unrelated thought (TUT; a commonly studied variety of mind wandering). However, at odds with this prediction, research has found that increasing motivation results in decreases in both intentional and unintentional TUTs. One possible explanation for this surprising finding is that standard assessments of TUT may inadvertently conflate TUTs with another variety of mind wandering unconstrained thought. If so, then deconfounding task-unrelated and unconstrained varieties of mind wandering might produce the predicted effect of a decrease in intentional, but not unintentional, TUT when motivation is increased. To explore this possibility, in the present study, participants completed a sustained-attention task after receiving standard instructions (normal-motivation condition) or instructions informing them that they could leave the study early if they achieved a certain level of performance (motivated condition).
