#1
Max M Hansmann, Mohand Melaimi, Guy Bertrand
Readily available room temperature stable organic mixed valence compounds are prepared by one-electron reduction of cyclic bis(iminium) salts [derived from cyclic (alkyl)(amino)carbenes] bridged by various spacers. These compounds show characteristic intervalence charge transfer (IV-CT) bands in the near-infrared (NIR). Cyclic voltammetry, EPR, IR, UV-VIS and X-ray studies, as well as DFT calculations, show that depending on the nature of the spacer, these mixed valence compounds range from class III to borderline class I/II...

BACKGROUND: This study sought to compare the prevalence of bullying victimization between adolescents with and without a disability and between adolescents with and without borderline intellectual functioning or intellectual disability (BIF/ID). We also sought to assess whether the relationships between either disability or BIF/ID and bullying victimization vary by gender and parental education. METHODS: The sample included 3,956 12- to 13-year-old adolescents who participated in Wave 5 of the Longitudinal Study of Australian Children...

Borderline resectable pancreatic cancer (BRPC) is an advanced tumor in contact with the surrounding major vessels, making R0 resection difficult to achieve. Neoadjuvant treatment is expected to provide substantial local control and prolong survival. However, there is no standard treatment. I therefore conducted a strategic literature search from January 2013 to September 2017 and identified 37 clinical studies of pancreatic cancer, including BRPC, to evaluate treatment interventions. Twenty (54%) studies were prospective...

BACKGROUND: Difficulty in controlling emotional impulses is a crucial component of borderline personality disorder (BPD) that often leads to destructive, impulsive behaviours against others. In line with recent findings in aggressive individuals, deficits in prefrontal amygdala coupling during emotional action control may account for these symptoms. METHODS: To study the neurobiological correlates of altered emotional action control in individuals with BPD, we asked medication-free, anger-prone, female patients with BPD and age- and intelligence-matched healthy women to take part in an approach-avoidance task while lying in an MRI scanner...

Sotos syndrome is a congenital overgrowth disorder, associated with intellectual disability. Previous research suggests that Sotos syndrome may be associated with relative strength in verbal ability and relative weakness in non-verbal reasoning ability but this has not been explicitly assessed. To date, the cognitive profile of Sotos syndrome is unknown. Cognitive abilities of a large and representative sample of individuals with Sotos syndrome (N = 52) were assessed using the British Ability Scales (BAS3)...

Current technologies for removing heavy metal ions are typically metal ion specific. Herein we report the development of a broad-spectrum heavy metal ion trap by incorporation of ethylenediaminetetraacetic acid into a robust metal-organic framework. The capture experiments for a total of 22 heavy metal ions, covering hard, soft, and borderline Lewis metal ions, show that the trap is very effective, with removal efficiencies of >99% for single-component adsorption, multi-component adsorption, or in breakthrough processes...

Mothers suffering from borderline conditions are overwhelmed by emotions. Their interactions are tainted with qualitative discontinuities, unpredictable for infants. These high-risk situations must not be trivialised. They are characterised by the importance of providing rapid support to the baby and by the existence of maternal suffering. The infant's basic needs guide the professionals working with these families.

BACKGROUND: The correlation between the atherogenic index of plasma (AIP) and waist circumference (WC) remains unknown. METHODS: A total of 5351 middle-aged men living in Southeastern China were surveyed using the random stratified cluster sampling method. A WC of 90 cm or greater was indicative of abdominal obesity, and AIP was calculated as follows: log [triglyceride (TG)/high-density lipoprotein-cholesterol (HDL-C)]. RESULTS: (1) A significantly higher AIP was observed in subjects with abdominal obesity than in those without abdominal obesity (P < 0·001)...

BACKGROUND: While associated with obesity, the cause of the rapid rise in prevalence of nonalcoholic fatty liver disease (NAFLD) in children, which is highest among Hispanics, is not well understood. Animal experiments have demonstrated that arsenic exposure contributes to liver injury. Our objective was to examine the association between arsenic exposure and NAFLD in humans and to determine if race/ethnicity modifies the association. METHODS: Urinary inorganic arsenic concentrations among those ≥12 years in the National Health and Nutrition Examination Survey, 2005-2014 were used to assess the cross-sectional association with serum alanine aminotransferase (ALT) levels, a marker of liver dysfunction...

Pancreatic cancer is known to be the deadliest of all common cancers. Despite all efforts in pancreatic cancer treatment, the five-year survival rates at diagnosis over the past 20 years have only increased from 5% to 8%. Assuming that pancreatic cancer is going to become the second most frequent cause of cancer related death in the next 20 years, we are all encouraged to treat patients in clinical trials to gain improvements in this devastating disease. Areas covered: This review will provide a summary of pancreatic cancer treatment over the last 20 years, starting with the pivotal study in 1997 which showed the superiority of gemcitabine over 5-FU in advanced pancreatic cancer and is marked as the beginning of a new era in pancreatic cancer treatment...

Intravenous thrombolysis (IVT) is a standard treatment for anterior (ACS) and posterior circulation stroke (PCS). However, due to the low occurrence of PCS and of intracranial hemorrhage (ICH) in PCS, the knowledge about ICH predictors following IVT in PCS is sparse. Our aim was to identify predictors for ICH following IVT in PCS. The set consisted of 1281 consecutive ischemic stroke (IS) patients treated with IVT, out of which 158 (103 males; mean age 65.6 ± 12.3 years) had PCS. Collected data include baseline characteristics, common stroke risk factors, pre-medication, stroke severity, admission blood glucose level, blood pressure and treatment with intravenous antihypertensive therapy before and during IVT, occlusion of arteries, recanalization rate, time to treatment, and clinical outcome at day 90...

We present a case of multiple osteolytic lesions in a 28-year-old adult who presented with headache, back pain, and hip pain of 6 months. There was no history of localized swelling or rise of temperature, no history of weight loss or evening rise of temperature. On examination, there were no focal neurological deficits. Routine laboratory investigations, including total leukocyte counts, differential leukocyte counts, hemoglobin, and platelet counts, were within normal limits. There was a borderline elevation of erythrocyte sedimentation rate...

Borderline and antisocial personality features relate to multiple externalizing behaviors, including intimate partner violence (IPV). However, not all individuals with borderline and antisocial traits perpetrate IPV. The strength of the personality-IPV link may be related to problematic substance use. We examined borderline and antisocial personality features, problematic substance use, and IPV in a community sample of couples. Positive relations between both borderline and antisocial features and IPV were stronger in conditions of high problematic alcohol use relative to low problematic alcohol use...

BACKGROUND: Phyllodes tumors (PT) are uncommon biphasic tumors, accounting for less than 1% of all breast primary neoplasms. They form a wide variety of tumors ranging from benign to malignant. Several histological features are used to grade PT into 3 categories: benign (grade I), borderline (grade II) and malignant (grade III) tumors. The aim of our study was to analyse histolopathological, radiological and clinical features of PT from an experience of a single center. METHODS: It was a retrospective study including 106 patients diagnosed with phyllodes tumors on surgical specimens at the department of pathology, of Hassan II university hospital (Fez, Morocco), from 2009 to 2016...
