Our findings open the possibility for a major change in how the Eyes Test is used to inform diagnosis in ASD. LAY SUMMARY The Eyes Test is used worldwide to inform autism spectrum disorders (ASD) diagnosis. We show here that ASD and neurotypical adults show the most difference in performance on subgroups of items ASD adults do not improve as expected when comparing easy and difficult items, and they do not show an improvement for items displaying a positive feeling. We advise clinicians to focus on these comparisons to increase the property of the test to distinguish people with ASD from neurotypical adults.
Despite many efforts, reliable biomarkers for the prediction and diagnosis of colorectal cancer (CRC) are still missing. Insulin-like growth factor 1 (IGF-1) and E-cadherin are recognized as potential biomarkers, but their diagnostic capacity is largely unexplored in CRC. The aim of this work is to investigate IGF-1 and E-cadherin levels with respect to various characteristics of CRC and to estimate their diagnostic potential.

Seventy CRC patients and 75 healthy individuals were enrolled. IGF-1 and E-cadherin were determined using enzyme-linked immunosorbent assay. The predictive and diagnostic capacities of IGF-1 and E-cadherin were estimated by logistic regression analysis and by determination of the area under the receiver operating characteristic (ROC) curve (AUC).

Concentrations of IGF-1 were lower (P=0.019) while levels of E-cadherin were higher (P<0.001) in CRC patients than in controls. IGF-1 concentration decreased in parallel with age and progression of CRC (P=0.023). Also, IGF-1 was higherle E-cadherin demonstrated high diagnostic accuracy.
Caesarean delivery on maternal request (CDMR) is considered a significant contributor to the unprecedented increase in caesarean deliveries (CDs) for nonclinical reasons. Current literature lacks a reliable assessment of the rate of CDMR, which hinders the planning and delivery of appropriate interventions for reducing CDMR rates.

To conduct a systematic review of the literature and meta-regression to explore the global incidence of CDMR.

PubMed, Embase, CINAHL, Medline, Google scholar and grey literature were searched from January 1985 to May 2019.

Observational studies that report CDMR data were included. We excluded non-English articles, case notes, editorial reviews and articles reporting elective CDs from pregnancy risk factors.

Two reviewers independently conducted the screening and quality appraisal using a validated tool. The weighted average of CDMR over total deliveries (absolute proportion) and by total CDs (relative proportion) were generated. Quality-effects meta-regression was used to explain the variability of the CDMR estimates by moderators, including study methodology and demography of study participants.

We identified 31 articles from 14 countries that include 5million total births. The absolute proportion of CDMR varies between 0.2 and 42.0%, with significant variations across studies and subgroups. The economic status of the country and study year together explained 84% of the absolute and 76% of the relative proportion of CDMR variation.

An appropriate reporting of CDMR should be a key priority in maternal health policies and practices.

Globally, the proportion of maternal requested caesarean delivery has mostly been influenced by the economic status of the country.

Constructing heterostructure and oxygen vacancies have demonstrated great promises to boost the OER performance. Herein, we report a facile strategy to fabricate hetero-structured NiFe2 O4 /Ni3 S4 nanorods, where NiFe2 O4 can be derived from Fe-based metal-organic frameworks (MOFs). The NiFe2 O4 /Ni3 S4 catalyst exhibited excellent OER performance, evidenced by an overpotential value of 357 mV at the current density of 20 mA cm-2 , and a small Tafel slope of 87.46 mV dec-1 in 1 M KOH, superior to the benchmark IrO2 catalyst. Moreover, NiFe2 O4 /Ni3 S4 outperformed with regard to long-term durability for OER than IrO2 . Actinomycin D in vitro Such outstanding OER performance is mainly accounted by the interface between NiFe2 O4 and Ni3 S4 , and the presence of rich oxygen vacancies. When employed as air-cathode in zinc-air batteries, the NiFe2 O4 /Ni3 S4 decorated battery had a high round-trip efficiency of 62.1% at 10 h, and possessed long-term stability of >50 h. This study may pave the way for fabricating non-noble-metal-based cost-effective, efficient and durable electrocatalysts for OER, zinc-air batteries, and beyond.Cell penetrating peptides (CPPs), known as protein translocation domains, have emerged as efficient molecular transporters to overcome biological barriers and deliver cell-impermeable cargoes into cells. The conjugation of CPPs to polymeric nanoplatforms enhances the drug delivery efficiency thus increasing their therapeutic efficacy. However, conventional CPPs are generally lack of cell specificity and could be easily degraded in vivo. These limitations lead to the development of new CPPs with superior properties. To address the issue of cell specificity, activatable CPPs have been designed to be activated at desired site through different stimuli. On the other hand, macrocyclization has been used to constrain linear CPPs into their cyclic forms. This chemical optimization of peptides endows CPPs with enhanced stability and cell permeability. This brief review will cover recent advances in terms of different types of CPPs for enhanced cell penetration. In addition, the modification chemistry used to functionalize polymeric nanoplatforms with CPPs and their recent applications for drug delivery will also be discussed.
