Article Abstract
The CSP, EMP2/MESA, MSP2, MSP3, MSP5, RAP1, RAP2, RESA1, SERA1 and SSP2/TRAP genes of Plasmodium falciparum are vaccine candidates. The hepatic phase of the infection is of major interest due to the protection induced by immunization with radiation-attenuated sporozoites. We therefore performed RT-PCR experiments to determine whether these genes are transcribed during this phase. Whereas transcripts of the CSP gene were detectable only in sporozoites, transcripts of the MSP2, MSP5, RAP1, RAP2, SERA1 and SSP2/TRAP genes were present in both sporozoites and infected hepatocytes. Transcripts of the EMP2/MESA gene were detectable only in infected hepatocytes. Transcripts of the MSP3 and RESA1 genes were not detectable in sporozoites or in infected hepatocytes. Genes presently identified as being transcribed during the hepatic phase may be of interest with respect to the design of preventative vaccination strategies.
Objectives: To investigate the feasibility of radiomics models for predicting the source of hepatic metastases from gastrointestinal (GI) vs. non-gastrointestinal (non-GI) primary tumors on contrast enhanced CT(CECT).
Methods: 347 patients with liver metastases (180 from GI and 167 from non-GI) and abdominal CECT including arterial, portal venous, and delayed phases were divided into training (221) and validation (96) sets at a ratio of 7:3 and an independent testing set (30).

Background & Aims: Owing to unexplained interpatient variation and treatment failure in hepatocellular carcinoma (HCC), novel therapeutic approaches remain an urgent clinical need. Hepatic neurons, belonging to the autonomic nervous system (ANS), mediate liver/whole body crosstalk. Pathological innervation of the ANS has been identified in cancer, nurturing tumor stroma and conferring stronger carcinogenic properties.
Background And Objectives: Epcoritamab is a CD3xCD20 bispecific antibody approved for the treatment of adults with different types of relapsed or refractory (R/R) B cell non-Hodgkin lymphoma (B-NHL) after ≥ 2 lines of systemic therapy. Here we report the first results from a population pharmacokinetic model-based analysis using data from 2 phase 1/2 clinical trials (EPCORE NHL-1, NCT03625037 and EPCORE NHL-3, NCT04542824) evaluating epcoritamab in patients with R/R B-NHL.
Methods: Plasma concentration-time data included 6819 quantifiable pharmacokinetic samples from 327 patients with R/R B-NHL.
Background: Interleukin-23 inhibition is effective in treating ulcerative colitis. Guselkumab is a dual-acting, human IgG1, interleukin-23p19 subunit inhibitor that potently neutralises interleukin-23 and can bind to CD64. We aimed to evaluate the efficacy and safety of guselkumab as induction and maintenance therapy in patients with ulcerative colitis.

Background: Not all malignant tumors, especially in hepatocellular carcinoma (HCC) patients with cirrhosis, can be detected by preoperative imaging methods. Therefore, it is urgently necessary to improve the intraoperative detectability of HCCs. Contrast-enhanced intraoperative ultrasonography (CE-IOUS) is an effective technique for detecting and characterizing occulting HCC lesions.
