    This work provides a comprehensive large-scale quantitative foundation for studying neuron-astrocyte interactions. MAIN POINTS Large scale detection of 3D astrocytic domains following CLARITY. Different distributions of neuronal content in CA1 and BLA astrocytic domains. SST neurons are located in close proximity to neighboring astrocytes, relative to PV, and VIP neurons.

    The hybrid glycophorins of MNS blood group system express a series of low incidence antigens including Mi

    , which are commonly found in Southeast Asian populations. In this study, the molecular basis of Mi

    -positive hybrid glycophorins was firstly clarified in the Chinese Southern Han population. RNA transcripts of GYPB gene in the homozygous GP.Mur individuals were also analyzed.

    DNAs were extracted from the whole blood samples of 111 Mi

    -positive donors. Then, high-resolution melting (HRM) analysis for GYP(B-A-B) was used to analyze the genotypes. Sequencing of GYPB pseudoexon 3 was conducted in the samples with variant melting curves. TA-cloning and subsequent sequencing of GYPA exons 2-4 were performed in the Mi

    -positive samples with normal GYPB/GYPB genotype by HRM. The transcript analysis of GYPB was conducted in homozygous GP.Mur and wild-type glycophorin B (GPB) individuals using RNA extracted from the cultured erythroblast.

    The heterozygous GYP*Mur/GYPB (n= 101), homozygous GYP*Mur/GYP*Mur (n= 7) including one novel GYP*Mur allele with an extra GYPA/GYPE specific nucleotide substitution (c.229+110A>T), heterozygous GYP*Bun/GYPB (n= 1) and GYP*Vw/GYPA (n= 2) with two novel GYP*Vw alleles were identified. RNA transcript analysis revealed multiple transcripts of GYPB existing in both homozygous GP.Mur and normal GPB individuals.

    The results showed the genetic diversity of hybrid glycophorins in the Chinese population. Besides, the successful analysis of GYPB transcripts indicates that the cultured erythroblast is a good source for RNA transcript analysis for the protein only expressed on the red blood cells.

    The primary objective was to demonstrate the relationship between lung ultrasound (LUS) manifestations and the outcomes of intensive care unit (ICU) patients. The secondary objective was to determine the characteristics of LUS manifestations in different subgroups of ICU patients.

    This prospective multi-center cohort study was conducted in 17 ICUs. A total of 1702 patients admitted between August 31, 2017 and February 16, 2019 were included. LUS was performed according to the bedside lung ultrasound in emergency (BLUE)-plus protocol, and LUS scores were calculated. Data on the outcomes and oxygenation indices were analyzed and compared between different primary indication groups.

    The LUS scores were significantly higher for non-survivors than for survivors and were significantly different between the oxygenation index groups, with higher scores in the lower oxygenation index groups. The LUS score was an independent risk factor for the 28-day mortality. The area under the receiver operating characteristic curve was 0.663 for prediction of the 28-day mortality and 0.748 for prediction of an oxygenation index ≤100.

    The LUS score based on the BLUE-plus protocol was an independent risk factor for the 28-day mortality and was important for the prediction of an oxygenation index ≤100. An early LUS score within 24 hours of ICU admission helps predicting the outcome of ICU patients.

    Outcome after ST-elevation myocardial infarction (STEMI) can be most reliably estimated by cardiac magnetic resonance (CMR) imaging. However, CMR is expensive, laborious, and has only limited availability. In comparison, transthoracic echocardiography (TTE) is widely available and cost-efficient.

    TTE strain parameters can be used as surrogate markers for CMR-measured parameters after STEMI.

    TTE strain analysis was performed of patients included in a controlled, prospective STEMI trial (NCT01777750) 4 ± 2 days after the event. Longitudinal peak strain (LPS), post-systolic shortening, early systolic lengthening, early systolic lengthening time, and time to peak shortening were measured, and index parameters were computed. Global longitudinal strain (GLS) and ejection fraction (EF) were compiled. Parameters were correlated with CMR-measured variables 4± 2 days after STEMI.

    In 70 STEMI patients, high quality CMR and TTE data were available. Highest correlation with CMR-measured infarct size was observed with GLS (r=0.577, p < 0.0001), LPS (r=0.571, p < 0.0001), and EF (r=-0.533, p < 0.0001). Highest correlation with CMR-measured area at risk was observed with GLS (r=0.666, p < 0.0001), LPS (0.661, p < 0.0001) and early systolic lengthening index (r=0.540, p < 0.0001). Receiver operating characteristics for the detection of large infarcts (quartile with highest infarct size) showed the highest area under the curve for LPS, GLS, EF, and myocardial dysfunction index. Multiple linear regression displayed the best association between GLS and infarct size.

    Exploratory strain parameters significantly correlate with CMR-measured area at risk and infarct size and are of potential interest as endpoint variables in clinical trials.

Harbouring such expectations may interfere with RCT participation experiences, particularly among marginalised populations, such as people with substance use disorders (PSUD) who may experience social and structural barriers to participation that also increase their vulnerability to therapeutic optimism. However, little research explores therapeutic optimism within substance use trials. Thus, we conducted a nested qualitative study within an RCT testing a treatment for alcohol and opioid use disorders in HIV clinics. Using interviews with 22 participants in Vancouver, Canada, analysis revealed themes relevant to therapeutic optimism, that were specifically linked to intrinsic (e.g. health-related) or extrinsic motivations (e.g. stipend). selleck products First, compared to extrinsically motivated participants, intrinsically motivated participants held high expectations for the trial and attributed greater agency to the study medication.
