Personality disorders, violence and antisocial behaviour: updated systematic review and meta-regression analysis.

Background: Links between personality disorders and antisocial outcomes has not examined individual personality disorders, and the contribution of comorbidities remain uncertain. Previous systematic reviews are dated.

Aims: To synthesise evidence from observational studies on the risk of antisocial outcomes and recidivism associated with personality disorders.

An umbrella review of adverse effects associated with antipsychotic medications: the need for complementary study designs.

Antipsychotic medications are widely prescribed in psychotic illnesses and other mental disorders. Effectiveness is well-established, particularly for reducing symptoms such as delusions and hallucinations, but can be impacted by tolerability. Adverse effects are wide-ranging, and vary between antipsychotics, which is clinically important.

Single-cell analysis of human basal cell carcinoma reveals novel regulators of tumor growth and the tumor microenvironment.

How basal cell carcinoma (BCC) interacts with its tumor microenvironment to promote growth is unclear. We use singe-cell RNA sequencing to define the human BCC ecosystem and discriminate between normal and malignant epithelial cells. We identify spatial biomarkers of tumors and their surrounding stroma that reinforce the heterogeneity of each tissue type.

PI3K Promotes Basal Cell Carcinoma Growth Through Kinase-Induced p21 Degradation.

Basal cell carcinoma (BCC) is a locally invasive epithelial cancer that is primarily driven by the Hedgehog (HH) pathway. Advanced BCCs are a critical subset of BCCs that frequently acquire resistance to Smoothened (SMO) inhibitors and identifying pathways that bypass SMO could provide alternative treatments for patients with advanced or metastatic BCC. Here, we use a combination of RNA-sequencing analysis of advanced human BCC tumor-normal pairs and immunostaining of human and mouse BCC samples to identify a PI3K pathway expression signature in BCC.

MTOR promotes basal cell carcinoma growth through atypical PKC.

Advanced basal cell carcinomas (BCCs) are driven by the Hedgehog (HH) pathway and often possess inherent resistance to SMO inhibitors. Identifying and targeting pathways that bypass SMO could provide alternative treatments for patients with advanced or metastatic BCC. Here, we use a combination of RNA-sequencing analysis of advanced human BCC tumor-normal pairs and immunostaining of human and mouse BCC samples to identify an MTOR expression signature in BCC.

PKC-ε pseudosubstrate and catalytic activity are necessary for membrane delivery during IgG-mediated phagocytosis.

In RAW 264.7 cells, PKC-ε regulates FcγR-mediated phagocytosis. BMDM behave similarly; PKC-ε concentrates at phagosomes and internalization are reduced in PKC-ε⁻/⁻ cells.

Genetic characterization of four Austronesian-speaking populations.

Ascertaining the genetic relationships between Austronesian populations is paramount to understanding their dispersal throughout the islands of the Pacific and Indian Oceans. The start of the Austronesian expansion has been dated to approximately 6,000 years ago, and from linguistic and archeological evidence, the origin of this dispersal may have been the island of Formosa. Consequently, the Taiwanese aboriginal populations and their phylogenetic relationship to the Austronesian-speaking groups from Madagascar at the occidental fringes of the expansion are of great interest.

High-frequency acoustic emissions generated by a 20 kHz sonochemical horn processor detected using a novel broadband acoustic sensor: a preliminary study.

This paper describes the application of a novel broadband acoustic sensor to evaluating the acoustic emissions from cavitation produced by a typical commercial 20 kHz sonochemical horn processor. Investigations of the reproducibility of the processor, and of the variation in cavitation emissions as a function of output setting and sensor location are described, and resulting trends discussed in terms of the broadband integrated power in the megahertz frequency range. Companion studies with a conventional membrane hydrophone have illustrated for the first time that cavitation emissions produced by a sonochemical horn processor can extend to frequencies beyond 20 MHz, and the sensor shows that significant nonlinearity can be seen in measured cavitation activity with increasing nominal output power.

The microscopic visualisation of the sonocrystallisation of ice using a novel ultrasonic cold stage.

This work reports dynamic video images of the influence of ultrasonic cavitation on the sonocrystallisation of ice at a microscopic level. This has been achieved through the construction of a unique ultrasonic system for an optical microscope. The system consists of (1).

The sonocrystallisation of ice in sucrose solutions: primary and secondary nucleation.

Two investigations of the sonocrystallisation of ice are reported for solutions in the concentration range of 0-45 wt.% sucrose. The first, carried out at 20 kHz using a commercial sonicator shows clear evidence of the stimulation of primary nucleation, by increasing the temperature at which nucleation takes place.
