Summary: Lung cancer has the highest mortality rate among all tumor types, largely due to uncontrolled cellular proliferation. [F-18]FLT-PET offers a non-invasive method to accurately assess cell proliferation rates, improving the accuracy of diagnosis, staging, and therapy response evaluation for lung cancer.

Summary: This study evaluated the use of radiomics-based advanced textural features from F-18-FLT-PET/CT images to predict tumor response to neoadjuvant chemotherapy in locally advanced breast cancer. The results suggest that a model based on PET radiomic characteristics could potentially have good discriminatory capacity for early response monitoring before the end of treatment. The combination of SUVmax and certain textural features were identified as useful for classifying PET response, while a different combination was found useful for classifying pathological response.

Summary: A new phosphate bioisostere, [F-18]SqFLT, was designed for PET imaging and showed low tracer uptake in vitro compared to traditional bioisosteres, while effectively discriminating between different cell lines in vivo. However, the current form of the radiotracer, [F-18]SqFLT, lacked an effective tissue retention mechanism in vivo, making it unsuitable for PET imaging of proliferation.

Summary: Some EGFR-mutant, MET-amplified lung cancers may develop dependence on MET activation alone, suggesting that these patients could be treated with a single-agent MET TKI instead of the current standard-of-care EGFR and MET inhibitor combination regimens.

Summary: This study investigates the role of F-18-fluorodeoxyglucose positron emission tomography/computed tomography (F-18-FDG PET/CT) in early prediction of response and survival following EGFR-TKI therapy in patients with advanced lung adenocarcinomas and EGFR mutations. The results show that F-18-FDG PET/CT can achieve early prediction of outcomes in these patients.

Summary: C-Met, a receptor tyrosine kinase overexpressed in various cancer types, has potential as a biomarker for cancer imaging and therapy. This study synthesized and evaluated an [F-18]AlF-labelled analogue, [F-18]AlF-EMP-105, for c-Met imaging using positron emission tomography. In vitro evaluation showed high specificity of [F-18]AlF-EMP-105 for c-Met-expressing cells. PET imaging in mice demonstrated renal clearance of the tracer predominantly as [F-18]fluoride. [F-18]AlF-EMP-105 shows promise as a diagnostic tool for imaging cancer due to its high specificity for c-Met expressing cells.

Summary: MET fusions are rare in lung cancer patients, with an occurrence rate of 0.2% to 0.3%. In this study, intragenic MET fusions were found in 52.6% of the included patients. Crizotinib was effective in treating MET fusions, including a new type called EML4-MET fusion. This study sheds light on the rarity and therapeutic potential of MET fusions in lung cancer.

Summary: This study systematically evaluated the role of genetic variants in A-to-I editing genes on the prognosis of NSCLC patients receiving EGFR-TKIs therapy. The researchers identified several SNPs in the ADAR gene that were significantly associated with patient prognosis and found that silencing ADAR enhanced the sensitivity of NSCLC cells to gefitinib. These findings highlight the importance of A-to-I RNA editing in drug resistance and suggest ADAR as a potential therapeutic target for unresectable NSCLC.

Summary: Notch1 and EGFR are two different surface receptors in cancer cells, with high levels of active Notch1 leading to resistance to EGFR inhibitors by regulating the promoter activity of the EGFR gene and causing a reversible shift of driver dependence from EGFR to Notch1.

Summary: Marine toxins have a significant impact on seafood resources and human health. This study focused on screening and identifying bioactive compounds produced by Gambierdiscus balechii, a toxic microalgae species, using liquid chromatography-high resolution mass spectrometry and in vitro cell-based bioassays. The study identified CTX-like and MTX-like toxicity in fractions of the algal extract, and confirmed the presence of a putative I/C-CTX congener. This research has important implications for understanding ciguatera poisoning and developing analytical methods for its detection.

Summary: This study aimed to determine the normal pituitary size and pituitary-to-brain ratio in domestic short-haired cats using computed tomography. The study found that the normal range for pituitary dimensions is wider than previously reported and there is a low correlation between body weight, age, and pituitary dimensions. The reference values obtained from this study could help in better evaluating suspected pituitary neoplastic lesions in domestic short-haired cats.

Summary: This study aimed to assess the feasibility and standardize the modality of retrobulbar fat injection for the treatment of enophthalmos in dogs. The injection of adipose tissue-like solutions within the retrobulbar space was performed in dog cadavers using an ultrasound-guided approach. Eyeball displacement was evaluated using computed tomography (CT), and necropsy and histopathological examination were conducted to assess retrobulbar structure damage. The study concluded that retrobulbar fat injection may represent a viable treatment option for enophthalmos in dogs.
