LARP6 regulates the mRNA translation of fibrogenic genes in liver fibrosis.

Unlabelled: Metabolic syndrome and excessive alcohol consumption result in liver injury and fibrosis, which is characterized by increased collagen production by activated Hepatic Stellate Cells (HSCs). LARP6, an RNA-binding protein, was shown to facilitate collagen production. However, LARP6 expression and functionality as a regulator of fibrosis development in a disease relevant model remains elusive.

Inhibition of RNA splicing triggers CHMP7 nuclear entry, impacting TDP-43 function and leading to the onset of ALS cellular phenotypes.

Amyotrophic lateral sclerosis (ALS) is linked to the reduction of certain nucleoporins in neurons. Increased nuclear localization of charged multivesicular body protein 7 (CHMP7), a protein involved in nuclear pore surveillance, has been identified as a key factor damaging nuclear pores and disrupting transport. Using CRISPR-based microRaft, followed by gRNA identification (CRaft-ID), we discovered 55 RNA-binding proteins (RBPs) that influence CHMP7 localization, including SmD1, a survival of motor neuron (SMN) complex component.

Experimental measurements of the granular density of modes via impact.

The jamming transition is an important feature of granular materials, with prior work showing an excess of low-frequency modes in the granular analog to the density of states, the granular density of modes. In this work, we present an experimental method for acoustically measuring the granular density of modes using a single impact event to excite vibrational modes in an experimental, three-dimensional, granular material. We test three different granular materials, all of which are composed of spherical beads.

Double dosing ulipristal acetate emergency contraception for individuals with obesity: a randomised crossover trial.

Objective: To determine whether increasing the dose of ulipristal acetate (UPA)-containing emergency contraception (EC) improves pharmacodynamic outcomes in individuals with obesity.

Study Design: We enrolled healthy, regularly-cycling, confirmed ovulatory, reproductive-age individuals with body mass index (BMI) >30 kg/m and weight >80 kg in a randomised crossover study. We monitored participants with transvaginal ultrasound and blood sampling for progesterone, luteinising hormone (LH), and estradiol every other day until a dominant follicle measuring >15 mm was visualised.
