Interestingly, selective activation of aryl halides has been demonstrated by adding reactive aryl halides to the η(2) -coordination complexes. The product distribution can be controlled by the concentration of the reactants and/or the presence of excess phosphine.One of the main challenges posed by the emergence of new psychoactive substances is their identification in human biological samples. Trying to detect the parent drug could lead to false-negative results when the delay between consumption and sampling has been too long. The identification of their metabolites could then improve their detection window in biological matrices. Oxidative metabolism by cytochromes P450 and glucuronidation are two major detoxification pathways in humans. In order to characterize possible CYP- and UGT-dependent metabolites of the 2-(4-bromo-2,5-dimethoxy-phenyl)-N-[(2-methoxyphenyl)methyl]ethanamine (25B-NBOMe), a synthetic psychoactive drug, analyses of human liver microsome (HLM) incubates were performed using an ultra-high performance liquid chromatography system coupled with a quadrupole-time of flight mass spectrometry detector (UHPLC-Q-TOF/MS). On-line analyses were performed using a Waters OASIS HLB column (30 x 2.1 mm, 20 µm) for the automatic sample loading and a Waters ACQUITY HSS C18 column (150 x 2 mm, 1.8 µm) for the chromatographic separation. Twenty-one metabolites, consisting of 12 CYP-derived and 9 UGT-derived metabolites, were identified. O-Desmethyl metabolites were the most abundant compounds after the phase I process, which appears to be in accordance with data from previously published NBOMe-intoxication case reports. Although other important metabolic transformations, such as sulfation, acetylation, methylation or glutathione conjugation, were not studied and artefactual metabolites might have been produced during the HLM incubation process, the record of all the metabolite MS spectra in our library should enable us to characterize relevant metabolites of 25B-NBOMe and allow us to detect 25B-MBOMe users.

This study aimed to explore relatives' perceptions of violent episodes and their suggestions on managing violence.

Qualitative design with focus groups including relatives (n = 8) was carried out. Data were analyzed using inductive content analysis.

The relatives described patient violence in different contexts at home, in a psychiatric hospital, and after discharge from the psychiatric hospital. They suggested interventions to achieve safer and more humane management of violent episodes.

Relatives are a valuable source of information in developing strategies to manage patient violence humanely. Their views on developing the quality of psychiatric care merit more attention.

We have analyzed the functional role of TTG15/UGT80B1 gene of Arabidopsis thaliana in freeze/thaw and heat shock stress using T-DNA insertional sgt knockout mutants. Quantitative study of spatial as well as temporal gene expression showed tissue-specific and dynamic expression patterns throughout the growth stages. Comparative responses of Col-0, TTG15/UGT80B1 knockout mutant and p35STTG15/UGT80B1 restored lines were analyzed under heat and freeze stress conditions. Heat tolerance was determined by survival of plants at 42°C for 3 h, MDA analysis and chlorophyll fluorescence image (CFI) analysis. Freezing tolerance was determined by survival of the plants at -1°C temperature in non-acclimatized (NA) and cold acclimatized (CA) conditions and also by CFI analysis, which revealed that, p35STTG15/UGT80B1 restored plants were more adapted to freeze stress than TTG15/UGT80B1 knockout mutant under CA condition. HPLC analysis of the plants showed reduced sterol glycoside in mutant seedlings as compared to other genotypes. Following CA condition, both β-sitosterol and sitosterol glycoside quantity was more in Col-0 and p35STTG15/UGT80B1 restored lines, whereas it was significantly less in TTG15/UGT80B1 knockout mutants. From these results, it may be concluded that due to low content of free sterols and sterol glycosides, the physiology of mutant plants was more affected during both, the chilling and heat stress.The fruit body of Lasiosphaera fenzlii was found to show cytotoxicity on cancer cells during a preliminary screening. Repeated column chromatography of the fungal methanol extract resulted in the isolation of six compounds identified as 5α,8α-epidioxy-ergosta-6,22-dien-3β-ol (1), 5α,8α-epidioxy-ergosta-6,9(11),22-trien-3β-ol (2), 5α-ergosta-7,22-dien-3β-ol (3), 5α-ergosta-7,22-dien-3-one (4), ergosta-7,22-dien-3β,5α,6β-triol (5) and 6-dihydroxy-2,3-dihydro-1H-isoindol-1-one (6). The two peroxide compounds, 1 and 2, showed cytotoxic activity and compound 1 was selectively cytotoxic to cancer cells. Furthermore, compound 1 synergised the cytotoxicity of paclitaxel on Hela cells by increasing intracellular accumulation of paclitaxel in cancer cells but not in normal cells.

In this radiographic and microbiologic split-mouth clinical trial, efficacy of a diode laser as an adjunct to conventional scaling in the nonsurgical treatment of peri-implantitis was investigated.

Eradication of pathogenic bacteria and infected sulcular epithelium presents a significant challenge in the nonsurgical treatment of peri-implantitis.

Ten patients (mean age, 55.1 years; SD, 11.4) with 48 two piece, rough-surface implants and diagnosed with peri-implantitis were recruited (NCT02362854). In addition to conventional scaling and debridement (control group), crevicular sulci and the corresponding surfaces of 24 random implants were lased by a diode laser running at 1.0 W power at the pulsed mode (λ, 810 nm; energy density, 3 J/cm(2); time, 1 min; power density, 400 mW/cm2; energy, 1.5 J; and spot diameter, 1 mm); (laser group). Healing was assessed via periodontal indexes (baseline and after 1 and 6 months after the intervention), microbiologic specimens (baseline and after 1 month), and radiographs (baseline and after 6 months).

Baseline mean pocket depths (4.71, SD, 0.67; and 4.38, SD 0.42 mm) and marginal bone loss (2.71, SD 0.11; and 2.88, SD 0.18 mm) were similar (p = 0.09 and p = 0.12) between the control and laser groups, respectively. After 6 months, the laser group revealed higher marginal bone loss (2.79, SD 0.48) than the control groups (2.63, SD 0.53) (p < 0.0001). However, in both groups, the microbiota of the implants was found unchanged after 1 month.

In this clinical trial, adjunct use of diode laser did not yield any additional positive influence on the peri-implant healing compared with conventional scaling alone.

The relationship between moderate/severe traumatic brain injury (TBI) and cognitive deficits is well known. The nature, duration and predictors of cognitive difficulties post-mild TBI remain unclear. This study examined cognitive, mood and post-concussion outcomes of mild TBI over 1-year post-injury.

Adults (>15 years) with mild TBI (n = 260) completed neuropsychological (CNS-Vital Signs, Behavioural Dyscontrol Scale), mood (Hospital Anxiety Depression Scale) and behavioural assessments (Cognitive Failures Questionnaire, Rivermead Post-Concussion Questionnaire) at baseline, 1-, 6- and 12-months post-injury.

Over the 12-months post-injury self-reported cognition (p = 0.027), post-concussion symptoms (p < 0.001), depression (p < 0.001), anxiety (p < 0.001) and dyscontrol (p = 0.025) improved significantly. Assessments of memory, processing speed, executive function, psychomotor speed/reaction time, complex attention and flexibility also improved significantly. At baseline >20% of individualo post-concussion symptoms, mood and self-reported cognitive outcomes. This implies a longer trajectory for recovery than has previously been suggested, which has implications for provision of assessment and rehabilitation services for more extended periods.

There is no consensus regarding the best treatment for intestinal follicular lymphoma (FL). We used "watch and wait" for patients with intestinal FL with low-tumor-burden (LTB) criteria and without mass formation causing bowel obstruction. We investigated the overall survival (OS) and time to treatment required (TTR).

Thirty-three intestinal FL patients [clinical stage (CS) I16, II10, II27, IV10; median observation period 45.5 months, range 13-110 months] were diagnosed via endoscopy. Detailed clinical and pathological examinations were performed, and neoplastic process behavior was monitored.

All of the 33 patients were WHO grade 1. Sodium palmitate cell line FL lesions in the digestive tract were found frequently in the second-fourth portion of the duodenum in 91% of the patients; 87% of those patients had lesions in a broader area including the small intestine. Two patients had an enlargement of the area of the lesions and a worsening of the macroscopic findings. Three patients had CS progression; however, these remained within the indication for "watch and wait." Two patients with transformation into diffuse large B-cell lymphoma received rituximab and chemotherapy, which led to complete remission. The OS was 100%. The time to treatment required (TTR) was 49 months in one patient and 37 months in one patient.

Intestinal FL in CS I-IV with broad infiltration of the digestive tract meeting the criteria for LTB had a remarkably slow course. This study suggests that "watch and wait" is appropriate for the treatment of LTB intestinal FL even in the era of rituximab.

Pre-eclampsia is the result of impaired trophoblast invasion and spiral artery remodeling managed by inflammatory response in its etiology and physiopathology. The aim of this study was to compare serum molecules including IL-33, ADAMTS12, ADAMTS16 and ADAMTS18 levels between pre-eclampsia and control groups and to investigate the role of these molecules in pre-eclampsia.

Forty-one women diagnosed as pre-eclampsia between 30 and 40 weeks of gestation and 41 non-complicated pregnant women were enrolled in this cross-sectional, case-control prospective study. ELISA method was used to determine IL-33, ADAMTS12, ADAMTS16 and ADAMTS18 levels within serums in two groups.

Serum ADAMTS12 and IL-33 levels were significantly lower in pre-eclampsia group (p < 0.001 and p 0.028, respectively), however, in sub-group analysis, no significant difference was observed (p > 0.05). The cut-off value of ADAMTS12 levels to discriminate pre-eclampsia with %73.17 sensitivity and %92.68 specificity was 8.27 ng/ml while the cut-off value for IL-33 was 0.
