A Multiple-Model-Informed Drug-Development Approach for Optimal Regimen Selection of an Oncolytic Virus in Combination With Pembrolizumab.

The antitumor efficacy of an intratumoral injection of a genetically engineered oncolytic vaccinia virus carrying human IL-7 and murine IL-12 genes (hIL-7/mIL-12-VV) was demonstrated in CT26.WT-bearing mice. In the CT26.

Enhanced Synthesis, Purification, and Characterization of a Marine Bacterial Consortium-Derived Protease Enzyme With Destaining and Keratinolytic Activity.

Two marine-derived bacteria, Bacillus paralicheniformis (HR-1) and Bacillus haynesii (HR-5), were isolated from sediments and identified using 16S ribosomal RNA gene amplification and sequencing as well as biochemical analysis. The development of a bacterial consortium (HR-1 & HR-5) from these two bacteria was used to increase the production of the protease enzyme under various conditions, including fermentation media, carbon and nitrogen sources (1% w/v), different pH levels, incubation time, and the obtained enzyme, were detected using SDS-PAGE followed by purification. Bacterial consortium HR-1 & HR-5 exhibited maximum protease production (330.

The effect of time from surgery to commencing adjuvant radiotherapy for patients with head and neck squamous cell carcinoma.

Introduction: Studies reported inferior outcomes when radiotherapy starts >6-8 weeks post-surgery for head and neck squamous cell carcinoma (HNSCC) but are limited due to time variable dichotomization. We assessed the relationship between survival and the time between surgery and radiotherapy as a continuous variable, hypothesising there would be no change in patients' survival at 6-8 weeks post-surgery.

Methods/materials: Inclusion criteria: patients with HNSCC who underwent surgery and adjuvant (chemo)radiotherapy, Jan 2014-Dec 2020.

Healthcare providers' experiences of maternity care service delivery during the COVID-19 pandemic in the United Kingdom: a follow-up systematic review and qualitative evidence synthesis.

Problem And Background: During the COVID-19 pandemic, there was substantial reconfiguration of maternity care services, affecting both users and healthcare providers (HCPs), in the United Kingdom (UK) and globally.

Aim: To further our understanding of the impact of maternity service reconfigurations in the UK, from the perspective of maternity HCPs.

Methods: Scopus, MEDLINE, EMBASE, CINAHL, PsycINFO and the Cochrane COVID Study Register were searched for relevant studies reporting qualitative data from the UK, published in English between 01 June 2021 and 30 September 2023.

Extracellular Vesicles From Preeclampsia Disrupt the Blood-Brain Barrier by Reducing CLDN5.

Background: The physiopathology of life-threatening cerebrovascular complications in preeclampsia is unknown. We investigated whether disruption of the blood-brain barrier, generated using circulating small extracellular vesicles (sEVs) from women with preeclampsia or placentae cultured under hypoxic conditions, impairs the expression of tight junction proteins, such as CLDN5 (claudin-5), mediated by VEGF (vascular endothelial growth factor), and activation of KDR (VEGFR2 [VEGF receptor 2]).

Methods: We perform a preclinical mechanistic study using sEVs isolated from plasma of pregnant women with normal pregnancy (sEVs-NP; n=9), sEVs isolated from plasma of women with preeclampsia (sEVs-PE; n=9), or sEVs isolated from placentas cultured in normoxia (sEVs-Nor; n=10) or sEVs isolated from placentas cultured in hypoxia (sEVs-Hyp; n=10).
