Tumour-induced osteomalacia (TIO), also known as oncogenic osteomalacia, is a rare paraneoplastic syndrome mediated by the overproduction of phosphaturic hormone fibroblast growth factor 23. TIO is most commonly caused by mesenchymal tumours (PMTs), which are typically small, slow-growing and often undetectable on physical examination and conventional imaging techniques. Patients with TIO typically undergo a protracted period of diagnostic workup and medical treatment due to presentation with nonspecific symptoms and difficulty in localising the culprit tumour.

Article Synopsis
  • The study investigates the link between high HbA1c levels and the severity of coronary artery disease (CAD) in patients diagnosed with acute coronary syndrome (ACS).
  • It involved 120 patients with different types of ACS who were also diagnosed with diabetes, measuring their HbA1c levels and performing coronary angiography to assess CAD severity.
  • Results showed that higher HbA1c levels (especially above 10.5%) were associated with more severe forms of CAD, suggesting the need for optimal glycemic control to reduce cardiovascular risks.

Article Synopsis
  • * The study analyzed blood samples from 54 nonmetastatic BC patients, 46 metastatic BC patients, and 50 healthy individuals to investigate the relationship between specific biomarkers (miR-200a, lncRNA H-19, IL-6) and gene expression related to cancer metastasis.
  • * Findings revealed that levels of lncRNA H-19, miR-200a, and IL-6 were significantly higher in BC patients, particularly in those with metastatic disease, while SIRT-1 levels were lower, indicating a potential diagnostic role for these biomarkers

Food security is contingent upon increasing crop yields but also upon reducing crop losses to post-harvest pests and diseases. Weevils are particularly important agents of post-harvest losses in grain crops. A long-term evaluation of a biocontrol agent, Strain MS-8, at a single dose of 2 × 10 conidia kg of grain was formulated in kaolin as a carrier at levels of 1, 2, 3, and 4 g kg of grain and screened against the maize weevil, .

Several studies have linked Cancer stem cells (CSCs) to cancer resistance development to chemotherapy and radiotherapy. ALDH1A1 is a key enzyme that regulates the gene expression of CSCs and creates an immunosuppressive tumor microenvironment. It was reported that quercetin and resveratrol were among the inhibitors of ALDH1A1.

Background/aim: Artemisinin and its derivatives are not only approved antimalarial drugs but also exert strong anticancer activity. Based on the clinical activity of artesunate (ART) that has been previously reported in cervix carcinoma, we investigated a panel of 12 different biomarkers and identified the Wilms Tumor 1 (WT1) protein as a potential target of ART.

Patients And Methods: Matched biopsies of cervical carcinoma before, during, and after therapy from patients treated with ART were investigated for induction of apoptosis (TUNEL assay) and expression of Wilms Tumor protein 1 (WT1), 14-3-3 ζ, cluster of differentiation markers (CD4, CD8, CD56), ATP-binding cassette transporter B5 (ABCB5), glutathione S-transferase P1 (GSTP1), inducible nitric oxide synthase (iNOS), translationally controlled tumor protein (TCTP), eukaryotic elongation factor 3 (eIF3), and ADP/ATP translocase by immunohistochemistry.

Thyroid eye disease (TED) involves several pathogenic pathways and a battery of infiltrating mononuclear cells, cytokines, and chemokines in the orbit. Revealing the main molecules, which play a major role in the pathogenesis of TED, will help developing novel treatment strategies. In a multicenter, single-blind, case-control study, 60 tissue samples were collected during orbital decompression (44 TED patients) or non-TED related oculoplastic (16 controls) surgeries.

Background/aim: Multiple myeloma (MM) is characterized by accumulation of a malignant clone of plasma cells in the bone marrow. Curative treatments are not yet available. Therefore, we undertook a drug repurposing approach to identify possible candidates from a chemical library of 1,230 FDA-approved drugs by virtual drug screening.

Anti-angiogenesis targeting vascular endothelial growth factor receptor 2 (VEGFR2) has been considered an important strategy for cancer therapy. VEGFR2 inhibitors targeting tumor angiogenic pathways have been widely used in clinical cancer treatment. However, inherent or acquired resistance to anti-angiogenic drugs may occur and thus limit their clinical application.

Background/aim: Patients with metastatic tumors commonly have a poor prognosis. Frequently, patients suffering from progressive tumors have a high willingness for the compassionate use of non-approved medications. One of these medications is the antimalarial drug artesunate (ART) which also showed profound anticancer activity in vitro, in vivo, and in preliminary clinical pilot studies.

Background: Small cell vaginal carcinoma is a very rare gynecological cancer and treatments including chemo- and radiotherapy have had limited success.

Case Report: We report the case of a 37-year-old female, where intensive treatment with the combination of paclitaxel, carboplatin, irinotecan, and camptothecin with and without irradiation did not avoid metastasis of the tumor and the death of the patient. In an attempt to develop a strategy for individualized tumor therapy, we performed immunohistochemistry of 19 cancer-related proteins using a biopsy sample.

The design, fabrication, and characterization of wafer-scale, zero-bias power detectors based on 2D MoS field-effect transistors (FETs) are demonstrated. The MoS FETs are fabricated using a wafer-scale process on 8 μm-thick polyimide film, which, in principle, serves as a flexible substrate. The performances of two chemical vapor deposition MoS sheets, grown with different processes and showing different thicknesses, are analyzed and compared from the single device fabrication and characterization steps to the circuit level.

Crizotinib was a first generation of ALK tyrosine kinase inhibitor approved for the treatment of -positive non-small-cell lung carcinoma (NSCLC) patients. COMPARE and cluster analyses of transcriptomic data of the NCI cell line panel indicated that genes with different cellular functions regulated the sensitivity or resistance of cancer cells to crizotinib. Transcription factor binding motif analyses in gene promoters divulged two transcription factors possibly regulating the expression of these genes, i.

A series of eleven celastrol derivatives was designed, synthesized, and evaluated for their in vitro cytotoxic activities against six human cancer cell lines (A549, HepG2, HepAD38, PC3, DLD-1 Bax-Bak WT and DKO) and three human normal cells (LO, BEAS-2B, CCD19Lu). To our knowledge, six derivatives were the first example of dipeptide celastrol derivatives. Among them, compound 3 was the most promising derivative, as it exhibited a remarkable anti-proliferative activity and improved selectivity in liver cancer HepAD38 versus human normal hepatocytes, LO.
