33 vs 4.47 ± 3.83 μg/mL, p = 0.568). While first trimester copper concentrations were higher among diabetic women (187.26 ± 34.78 vs 175.17 ± 30.40 μg/L, p = 0.088), this was not statistically significant. The other element levels (zinc, selenium, and magnesium) were found to be similar between the two groups (p = 0.624, p = 0.088, p = 0.254, p = 0.872, respectively). The results of our study demonstrated that mean levels of afamin, vitamin E, and copper were higher in women with GDM compared to controls. Additionally, first trimester maternal zinc, selenium, and magnesium levels were similar between diabetic and healthy pregnant women. However, more studies are needed to clarify the relationship between blood trace concentrations and GDM.

During Covid-19 pandemic, the Italian government adopted restrictive limitations and declared a national lockdown on March 9, which lasted until May 4 and produced dramatic consequences on people's lives. The aim of our study was to assess the impact of prolonged lockdown on behavioral and psychological symptoms of dementia (BPSD).

Between April 30 and June 8, 2020, we interviewed with a telephone-based questionnaire the caregivers of the community-dwelling patients with dementia who had their follow-up visit scheduled from March 9 to May 15 and canceled due to lockdown. Among the information collected, patients' BPSDs were assessed by the Neuropsychiatric Inventory (NPI). Non-parametric tests to compare differences between NPI scores over time and logistic regression models to explore the impact of different factors on BPSD worsening were performed.

A total of 109 visits were canceled and 94/109 caregivers completed the interview. bpV clinical trial Apathy, irritability, agitation and aggression, and depression were the most common neuropsychiatric symptoms experienced by patients both at baseline and during Covid-19 pandemic. Changes in total NPI and caregiver distress scores between baseline and during lockdown, although statistically significant, were overall modest. The logistic regression model failed to determine predictors of BPSD worsening during lockdown.

This is one of the first studies to investigate the presence of BPSD during SARS-CoV-2 outbreak and related nationwide lockdown, showing only slight, likely not clinically relevant, differences in BPSD burden, concerning mostly agitation and aggression, anxiety, apathy and indifference, and irritability.

The mild cognitive impairment (MCI) is a neurocognitive disorder which involves cognitive impairments beyond those expected for the age and education of the subject but are not significant enough to interfere with instrumental activities of daily living. The identification of individuals with MCI is particularly important for those who might benefit from new therapies. The aim of this work is to propose a comprehensive neuropsychological protocol to achieve early diagnosis of MCI.

A neuropsychological battery was created and administered to a sample of patients with MCI (n = 25) and healthy matched controls (n = 25).

Although memory decline is often the first sign preceding the appearance of MCI, significant differences in visuospatial tasks, naming abilities, and executive function can be demonstrated as well between MCI and controls.

A proper selection of cognitive measures within those included in the already-available neuropsychological batteries may provide a thorough assessment of MCI and allow its timely diagnosis.

The defect-laden boron nitride (D-BN) was synthesized by a thermal polymerization route, in which melamine borate was used as a precursor. The defect microstructure was confirmed by photoluminescence (PL) and x-ray diffraction (XRD) techniques. As compared with h-BN, the D-BN-modified glassy carbon electrode (GCE) showed an enhanced electrochemical response towards Pb2+ peaking at - 0.551 V (vs. SCE), which was evidenced by linear sweep anodic stripping voltammetry (LSASV) results. The point defect plays a pivotal role in the electrocatalytic reaction process, which can mediate the electronic structure and surface properties of h-BN. Accordingly, the sensor presented a low detection limit of 0.15 μg/L towards Pb2+ and a wide linear response concentration range from 0.5 to 400 μg/L (correlation coefficient = 0.995). In view of its superior selectivity, stability, and reproducibility, the proposed method was applied for Pb2+ determination in real samples and exhibited satisfactory results. This work provides insight for the construction of electrochemical sensor with high-performance by engineering defects of modifying materials. Defect-loaden h-BN exhibited enhanced electrocatalytic redox reaction towards lead ions and thus a novel Pb2+ sensor with high performances was constructed.Metabotropic GABAB receptors (GABABRs) mediate slow inhibition and modulate synaptic plasticity throughout the brain. Dysfunction of GABABRs has been associated with psychiatric illnesses and addiction. Drugs of abuse alter GABAB receptor (GABABR) signaling in multiple brain regions, which partly contributes to the development of drug addiction. Recently, GABABR ligands and positive allosteric modulators (PAMs) have been shown to attenuate the initial rewarding effect of addictive substances, inhibit seeking and taking of these drugs, and in some cases, ameliorate drug withdrawal symptoms. The majority of the anti-addiction effects seen with GABABR modulation can be localized to ventral tegmental area (VTA) dopamine neurons, which receive complex inhibitory and excitatory inputs that are modified by drugs of abuse. Preclinical research suggests that GABABR PAMs are emerging as promising candidates for the treatment of drug addiction. Clinical studies on drug dependence have shown positive results with GABABR ligands but more are needed, and compounds with better pharmacokinetics and fewer side effects are critically needed.
