LPL-RH suppresses bone loss in ovariectomised rat models.

Background: Evidence has revealed that oestrogen deprivation-induced osteolysis is microbiota-dependent and can be treated by probiotics. However, the underlying mechanism require further investigation. This study aims to provide additional evidence supporting the use of probiotics as an adjuvant treatment and to explore the pathophysiology of oestrogen-deprived osteolysis.

Photothermal-manipulatable shape memory polyacrylamide/gelatin Janus hydrogel with drug carrier array for invasive wound closure and responsive drug release.

Traditional wound closure methods often present several issues, including additional puncture wounds, adverse effects from anesthesia, and noticeable scarring. Inspired by embryonic wound healing, a Janus hydrogel (PG/Au-Asp@PCM) is designed to manipulate non-invasive wound closure by photothermal-responsive self-contraction of PG/Au-Asp@PCM, which is attributed to the shape memory behavior of PG/Au-Asp@PCM under near-infrared (NIR). Wherein, gelatin acts as a thermally reversible "switch" and polyacrylamide creates stable and cross-linked "net-points".

Computed Tomography Coronary Angiography Is Feasible and Reliable for Proximal Coronary Segment Interpretation in Patients with Elevated Body Mass Index.

Computed tomography coronary angiography (CTCA) is under-utilised in detecting coronary artery disease (CAD) in obese patients due to concerns about non-evaluable testing. We hypothesise that these concerns are predominantly related to smaller and branch coronary vessels, and CTCA remains adequate for proximal segment stenosis interpretation, which has significant clinical implications. This retrospective cohort study, on consecutive patients referred for CTCA for suspected CAD, grouped patients by body mass index.

Improved efficacy of therapeutic HPV DNA vaccine using intramuscular injection with electroporation compared to conventional needle and needle-free jet injector methods.

Background: We have previously developed a candidate therapeutic HPV DNA vaccine (pBI-11) encoding mycobacteria heat shock protein 70 linked to HPV16/18 E6/E7 proteins for the control of advanced HPV-associated oropharyngeal cancer (NCT05799144). While naked DNA vaccines are readily produced, stable, and well tolerated, their potency is limited by the delivery efficiency. Here we compared three different IM delivery strategies, including intramuscular (IM) injection, either with a needle alone or with electroporation at the injection site, and a needle-free injection system (NFIS), for their ability to elicit gene expression and to improve the potency of pBI-11 DNA vaccine.

PEARL: A Multicenter Phase 2 Study of Lorlatinib in Patients with ALK-Rearranged NSCLC and Central Nervous System Disease.

Background: Patients with ALK-rearranged non-small cell lung cancer (ALK+ NSCLC) with symptomatic brain (BM) and leptomeningeal (LM) metastases are underrepresented in clinical trials due to poor performance status. Additionally, the need for improved and validated assessment criteria for evaluating central nervous system (CNS) response remains critical. Lorlatinib has demonstrated systemic activity in patients with ALK+ NSCLC.
