Daily oscillation of the excitation/inhibition ratio is disrupted in two mouse models of autism.

Alterations to the excitation/inhibition (E/I) ratio are postulated to underlie behavioral phenotypes in autism spectrum disorder (ASD) patients and mouse models. However, in wild type mice the E/I ratio is not constant, but instead oscillates across the 24-h day. Therefore, we tested whether E/I regulation, rather than the overall E/I ratio, is disrupted in two ASD-related mouse lines: KO and BTBR, models of syndromic and idiopathic ASD, respectively.

Evaluation of the neuroprotective effect of antipsychotics by serum quantification of protein S100B.

Objective: This research delves into the intricate interplay between antipsychotic medications and neuroprotection focusing on the S100B protein, a central player in the regulation of neuroapoptotic activity.

Method: Blood samples were collected to assess serum S100B protein levels using an immunoassay of immunoelectrochemiluminescence. The first two samples were collected with a 3-month interval between each, and the third sample was obtained 6 months after the previous one.

Dendrimer nanotherapy targeting of glial dysfunction improves inflammation and neurobehavioral phenotype in adult female Mecp2-heterozygous mouse model of Rett syndrome.

Rett syndrome is an X-linked neurodevelopmental disorder caused by mutation of Mecp2 gene and primarily affects females. Glial cell dysfunction has been implicated in in Rett syndrome (RTT) both in patients and in mouse models of this disorder and can affect synaptogenesis, glial metabolism and inflammation. Here we assessed whether treatment of adult (5-6 months old) symptomatic Mecp2-heterozygous female mice with N-acetyl cysteine conjugated to dendrimer (D-NAC), which is known to target glia and modulate inflammation and oxidative injury, results in improved behavioral phenotype, sleep and glial inflammatory profile.

Motivational interviewing: Validation of a proposed NIC nursing intervention in persons with a severe mental illness.

Introduction: Low adherence to treatment is a common problem in the care of patients with severe mental illnesses. Motivational interviewing is a directive, client-centered counseling therapeutic approach designed to elicit behavior change by helping clients to explore and resolve ambivalence. Nurses use motivational interviewing, although it has not been defined from a nursing perspective nor with nursing language.

Fabrication of patterned DNA surfaces.

Two photolithographic methods are described for the formation of patterned single or multiple DNA species on SiO2 substrates. In the first approach, substrates are treated with a photochemically labile organosilane monolayer film. Irradiation of these surfaces with patterned deep UV (193 nm) light results in patterned chemically reactive groups which are then reacted with heterobifunctional crosslinking molecules.
