Installation of a carbanionic substituent, that is strongly stabilized by two (trifluoromethyl)sulfonyl (Tf=SO2 CF3 ) groups, into several fluorescence dyes including boron-dipyrromethenes (BODIPYs), fluoresceins, and aminocoumarins has been achieved by the 2,2-bis(triflyl)ethylation reaction of the dye frameworks with highly electrophilic Tf2 C=CH2 , followed by neutralization with NaHCO3 . Despite the contradiction between water solubility and lipophilicity, the carbanion-decorated dyes thus obtained showed significant enhancement of not only water solubility but also lipophilicity. This work clearly demonstrates that the fluorinated, highly stabilized carbanionic substituent is a new option for controlling the macroscopic property of chemical materials.The loss of myelinating oligodendrocytes is a key characteristic of many neurological diseases, including Multiple Sclerosis (MS). In progressive MS, where effective treatment options are limited, peripheral immune cells can be found at the site of demyelination and are suggested to play a functional role during disease progression. In this study, we hypothesize that metabolic oligodendrocyte injury, caused by feeding the copper chelator cuprizone, is a potent trigger for peripheral immune cell recruitment into the central nervous system (CNS). We used immunohistochemistry and flow cytometry to evaluate the composition, density, and activation status of infiltrating T lymphocytes in cuprizone-intoxicated mice and post-mortem progressive MS tissues. Mitoquinone Our results demonstrate a predominance of CD8+ T cells along with high proliferation rates and cytotoxic granule expression, indicating an antigenic and pro-inflammatory milieu in the CNS of cuprizone-intoxicated mice. Numbers of recruited T cells and the composition of lymphocytic infiltrates in cuprizone-intoxicated mice were found to be comparable to those found in progressive MS lesions. Finally, amelioration of the cuprizone-induced pathology by treating mice with laquinimod significantly reduces the number of recruited T cells. Overall, this study provides strong evidence that toxic demyelination is a sufficient trigger for T cells to infiltrate the demyelinated CNS. Further investigation of the mode of action and functional consequence of T cell recruitment might offer promising new therapeutic approaches for progressive MS.

This study compared prevalence and hospital use among individuals frequently admitted to hospital in England with wholly attributable alcohol-related diagnoses (WAAD), known as alcohol-related frequent attenders (ARFAs), with those of non-alcohol frequent attenders (NAFAs), non-frequent alcohol attenders (ARNFAs) and non-alcohol non-frequent attenders (NANFAs).

Cross-sectional and longitudinal analyses of 5years of England's Hospital Episode Statistics (HES).

Hospital inpatients in England, UK, 2011-16.

Two cohorts (2011/12=489 580/7 654 944 patients and 2015/16=490 384/7 660 108 patients) were selected from all adult patients aged ≥18years, treated in English hospitals between 1 April 2011 and 31 March 2016. Patients were categorized as having alcohol-related admissions if diagnoses included a WAAD (ICD-10 classification, WHO, 2016) and frequent admissions if they had more than three hospital admissions during a single HES year.

Prevalence of ARFA, number of admissions (spells), occupied bed-days (epeated admissions for alcohol-related problems in England appear to be a high-cost, high-need, complex group of patients that makes up more than a quarter of the country's alcohol admissions.

To estimate 12-month prevalence and severity of mental disorders in the Saudi National Mental Health Survey (SNMHS).

The SNMHS is a face-to-face community epidemiological survey in a nationally representative household sample of citizens aged 15 to 65 in the Kingdom of Saudi Arabia (KSA) (n = 4,004). The World Health Organization (WHO) Composite International Diagnostic Interview (CIDI) was used to estimate 12-month prevalence of common DSM-IV mental disorders.

Twelve-month prevalence of any DSM-IV/CIDI disorder is 20.2%. Most common are anxiety disorders (12.3%) followed by mood (6.8%), disruptive behavior (5.4%), eating (3.2%), and substance use (1.9%) disorders. The proportion of 12-month cases rated serious (39.0% of all cases) is high across virtually all disorders relative to the proportions found in CIDI surveys in other high-income countries. Younger people have significantly elevated odds of mood and disruptive behavior disorders and serious disorders. Women have significantly elevated odds of anxiety and mood disorders and serious disorders. Previously married people have significantly elevated odds of most disorder classes and serious disorders.

Both 12-month prevalence and severity of DSM-IV/CIDI disorders are high in Saudi Arabia compared to other high-income countries that carried out comparable surveys.

To evaluate pregnancy-compatible phenotypic and functional changes in peripheral blood natural killer (pNK) cells during frozen embryo transfer (FET) cycles.

Peripheral blood was collected from patients undergoing frozen embryo transfer cycles at three separate time points in the cycle. pNK cell phenotype was analyzed by flow cytometry. Impact of pregnancy status on pNK cell cytotoxicity was characterized by two methods (1) a three-dimensional endovascular tube formation approach and (2) a NK cell-specific K562 cell kill assay.

A total of 35 patients were enrolled, 15 with clinical pregnancies and 20 with negative serum β-hCG levels. Overall percentage of CD45

pNK cell population on the day of serum β-hCG. pNK cells from non-pregnant patients caused significant tube disruption when compared to pregnant patients. Addition of serum from pregnant women reduced the tube disruption by pNK cells from non-pregnant patients. pNK cells from pregnant patients showed significantly lower cytotoxicity toward K562 cells in serum-free conditions. The addition of pregnancy serum decreased non-pregnant pNK cell cytotoxicity. Pregnancy status had no impact on VEGF-A and VEGF-C serum levels. Recombinant hCG added to non-pregnant serum resulted in a significant reduction in non-pregnant pNK cell-mediated K562 cell kill.

There was no difference in pNK cell populations based on timing of the FET cycle. However, pregnancy increased the percentage of CD45

pNK cells. Additionally, pNK cells from pregnant women have reduced cytotoxicity and this is possibly mediated by hCG.
