Article Synopsis
  • Low and middle-income countries face healthcare challenges due to limited resources, which could potentially be alleviated through telemedicine strategies.
  • A study in Istanbul analyzes the impact of telemedicine on patient travel, calculating the distance and time patients travel to receive care at cardiovascular clinics.
  • Implementing telemedicine could save significant travel distances, reduce carbon footprints by about 30%, and prevent substantial wage losses, ultimately improving access and reducing the burden on patients.

Background: Furan is an organic compound that occurs as a result of heat treatment during the processing and cooking of many food products. Furthermore, the environment contains furan in tobacco smoke and vehicle exhaust gases, and it serves as an intermediate molecule in the synthesis of various pharmaceutical and chemical agents, pesticides, and stabilizers. Studies on the male reproductive system have not been able to elucidate the pathway through which furan exerts its negative effects.

Background: Triple negative breast cancer (TNBC) is an aggressive subtype with poor prognosis. We aimed to determine whether circulating tumor DNA (ctDNA) and circulating tumor cell (CTC) could predict response and long-term outcomes to neoadjuvant chemotherapy (NAC).

Methods: Patients with TNBC were enrolled between 2017-2021 at The University of Texas MD Anderson Cancer Center (Houston, TX).

Article Synopsis
  • Triple-negative breast cancer (TNBC) patients often undergo neoadjuvant systemic therapy (NAST) to improve treatment outcomes.
  • A study analyzed multiparametric MRI scans from 163 TNBC patients at different stages of NAST to see if radiomic models could predict the likelihood of achieving a pathologic complete response (pCR).
  • The best predictive model, based on changes in MRI features after two cycles of treatment, showed a strong ability to forecast pCR with high accuracy, indicating that MRI could be useful for early treatment response assessments in TNBC.

Background: Interactions among tumor, immune, and vascular niches play major roles in driving glioblastoma (GBM) malignancy and treatment responses. The composition, heterogeneity, and localization of extracellular core matrix proteins (CMPs) that mediate such interactions, however, are not well understood.

Methods: Here, through computational genomics and proteomics approaches, we analyzed the functional and clinical relevance of CMP expression in GBM at bulk, single cell, and spatial anatomical resolution.

Importance: Biliary tract cancers (BTCs) contain several actionable molecular alterations, including FGFR2, IDH1, ERBB2 (formerly HER2), and KRAS. KRAS allelic variants are found in 20% to 30% of BTCs, and multiple KRAS inhibitors are currently under clinical investigation.

Objectives: To describe the genomic landscape, co-sequence variations, immunophenotype, genomic ancestry, and survival outcomes of KRAS-mutated BTCs and to calculate the median overall survival (mOS) for the most common allelic variants.

Purpose: Isocitrate dehydrogenase ()/ genomic alterations (GA) occur in 20% of intrahepatic cholangiocarcinoma (iCCA); however, the immunogenomic landscape of mutated iCCA is largely unknown.

Methods: Comprehensive genomic profiling (CGP) was performed on 3,067 cases of advanced iCCA. Tumor mutational burden (TMB), PD-L1 expression (Dako 22C3), microsatellite instability (MSI), and genomic loss of heterozygosity (gLOH) as a surrogate marker for homologous recombination deficiency were examined.

Since is a genus with many important medicinal plant species, the present work aimed to investigate the phytochemical composition and some biological activities of . The methanolic fractions of four organs (stems, flowers, leaves, root and whole plant) were quantified and identified by Liquid Chromatography Electrospray Ionization Tandem Mass Spectrometry (LC-ESI-MS/MS) analysis. Hesperidin, hyperoside, -hydroxybenzoic acid, protocatechuic acid and -coumaric acid were identified as main compounds among the extracts.

Unlabelled: Zanidatamab is a bispecific human epidermal growth factor receptor 2 (HER2)-targeted antibody that has demonstrated antitumor activity in a broad range of HER2-amplified/expressing solid tumors. We determined the antitumor activity of zanidatamab in patient-derived xenograft (PDX) models developed from pretreatment or postprogression biopsies on the first-in-human zanidatamab phase I study (NCT02892123). Of 36 tumors implanted, 19 PDX models were established (52.

The tumor suppressor gene is mutated early in most of the patients with triple-negative breast cancer (TNBC). The most frequent alterations are missense mutations that contribute to tumor aggressiveness. Here, we used an autochthonous somatic TNBC mouse model, in which mutant p53 can be toggled on and off genetically while leaving the tumor microenvironment intact and wild-type for p53 to identify physiological dependencies on mutant p53.

Article Synopsis
  • The study investigates the use of diffusion tensor imaging (DTI) to assess treatment response in women with triple-negative breast cancer (TNBC) undergoing neoadjuvant systemic treatment (NAST).
  • Out of 86 participants, 47% achieved a pathologic complete response (pCR), and DTI parameters showed significant differences between pCR and non-pCR patients during treatment.
  • Findings suggest that DTI measurements, particularly of the peritumoral region, could be valuable in predicting treatment outcomes for TNBC patients.

Article Synopsis
  • Early prediction of response to neoadjuvant systemic therapy (NAST) in patients with triple-negative breast cancer (TNBC) can help tailor treatments and prevent unnecessary side effects from ineffective therapies.
  • The study analyzed 163 TNBC patients using dynamic contrast-enhanced MRI to identify radiomic features that could indicate treatment response, focusing on areas around and within the tumors at different treatment stages.
  • Results showed promising predictive capabilities with certain radiomic features, as well as multivariate models, demonstrating significant accuracy in distinguishing between patients who achieved pathologic complete response (pCR) and those who did not, potentially enhancing early, non-invasive treatment assessments.

Determining concise sets of genomic markers that identify cell types and states within tissue ecosystems remains challenging. To address this challenge, we developed Recurrent Composite Markers for Biological Identities with Neighborhood Enrichment (RECOMBINE). Validations of RECOMBINE with simulation and transcriptomics data in bulk, single-cell and spatial resolutions demonstrated the method's ability for unbiased selection of composite markers that characterize biological subpopulations.

The interactions between tumor intrinsic processes and immune checkpoints can mediate immune evasion by cancer cells and responses to immunotherapy. It is, however, challenging to identify functional interactions due to the prohibitively complex molecular landscape of the tumor-immune interfaces. We address this challenge with a statistical analysis framework, immuno-oncology gene interaction maps (ImogiMap).

The large specific surface area and high conductivity of reduced graphene oxide (RGO) make it a promising material for supercapacitors. However, aggregation of graphene sheets into graphitic domains upon drying hampers supercapacitor performance by drastically impeding ion transport inside electrodes. Here, we present a facile approach to optimize charge storage performance in RGO-based supercapacitors by systematically tuning their micropore structure.

Article Synopsis
  • Early assessment of neoadjuvant systemic therapy (NAST) response is important for triple-negative breast cancer (TNBC) patients to prevent harmful side effects from ineffective treatments.
  • The study evaluated functional tumor volumes (FTVs) using dynamic contrast-enhanced (DCE) MRI after the 2nd and 4th cycles of NAST in 100 patients, finding FTVs at these points could indicate treatment response.
  • Results showed that 49% of patients achieved a pathologic complete response (pCR), with FTV at the 4th cycle having the best predictive accuracy (AUC = 0.84), while baseline FTV did not distinguish between pCR and non-pCR.

Therapeutic options for treatment of basal-like breast cancers remain limited. Here, we demonstrate that bromodomain and extra-terminal (BET) inhibition induces an adaptive response leading to MCL1 protein-driven evasion of apoptosis in breast cancer cells. Consequently, co-targeting MCL1 and BET is highly synergistic in breast cancer models.
