Flavonoids as promising anticancer therapeutics: Contemporary research, nanoantioxidant potential, and future scope
Phytother Res. 2023 Sep 5. doi: 10.1002/ptr.7975. Online ahead of print.ABSTRACTFlavonoids are natural polyphenolic compounds considered safe, pleiotropic, and readily available molecules. It is widely distributed in various food products such as fruits and vegetables and beverages such as green tea, wine, and coca-based products. Many studies have reported the anticancer potential of flavonoids against different types of cancers, including solid tumors. The chemopreventive effect of flavonoids is attributed to various mechanisms, including modulation of autophagy, induction of cell cycle arrest, apoptosis, and antioxidant...

Transcranial Direct Current Stimulation in Nicotine Use: Nursing Implications for Patient Outcomes
J Addict Nurs. 2023 Jul-Sep 01;34(3):E74-E78. doi: 10.1097/JAN.0000000000000542.ABSTRACTTobacco use is a leading cause of cancer, cardiovascular and respiratory disease, and preventable death in the United States. The brains of individuals with nicotine dependence are characterized by damaged mesolimbic pathways in the medial portion of the limbic and frontal lobes, creating positive reinforcing mechanisms. Transcranial direct current stimulation (tDCS) targets this neuroadaptation to improve smokers' nicotine-related outcomes, such as craving and smoking behavior, by depolarizing or hyperpolarizing the neurons of the brai...

Toward Precision Oncology in Glioblastoma with a Personalized Cancer Genome Reporting Tool and Genetic Changes Identified by Whole Exome Sequencing
This study demonstrates the prospects of precision/personalized medicine in GBM specifically, and neurosurgical oncology more generally, including the potential for genomic profiling coupled with personalized cancer genome reporting. Further research and larger studies are warranted to validate these findings and advance the treatment options and outcomes for patients with GBM.PMID:37669106 | DOI:10.1089/omi.2023.0117

Synthesis and in Vitro Cytotoxicity Evaluation of Jadomycins
In this study, we achieved the total synthesis of jadomycin T and jadomycin aglycons using L-threonine and 1-amino-2-propanol as nitrogen sources. Additionally, we evaluated the cytotoxic activity of eight compounds, including glycosides, jadomycin T, and their corresponding aglycons, in eight types of tumor cells. The evaluated jadomycins tended to exhibit stronger cytotoxic activity as aglycons than as glycosides. Although the presence of a 1,3-oxazolidine ring derived from an amino acid was not essential, the presence of the 1,3-oxazolidine ring showed strong activity when the ring had a carboxyl group. Furthermore, com...

Multilevel chitosan-gelatin particles loaded with P4HA1 siRNA suppress glioma development
Drug Deliv Transl Res. 2023 Sep 4. doi: 10.1007/s13346-023-01422-8. Online ahead of print.ABSTRACTIt has been reported that prolyl 4-hydroxylase subunit alpha 1 (P4HA1) promoted tumor growth and metastasis of glioma; thus, targeting P4HA1 may be a promising therapeutic strategy against glioma. In consideration of the instability of siRNA in vivo, the chitosan-gelatin microspheres loaded with P4HA1 siRNA (P4HA1 siRNA@CGM) were employed. Firstly, the gel electrophoresis and hemolytic test were performed to assess the stability and blood compatibility of P4HA1 siRNA@CGM. Then, methyl thiazolyl tetrazolium (MTT), cell colony f...

Anti-SOX-1 Antibody-Positive Paraneoplastic Limbic Encephalitis Diagnosed During Small Cell Lung Cancer Treatment
We present a case of anti-Sry-like high mobility group box 1 (SOX-1) antibody-positive PNS diagnosed during the treatment of small-cell lung cancer (SCLC). A 65-year-old woman with a history of smoking and SCLC (T3N1M0) was hospitalized to receive chemo-radiation therapy. On day 14, the course was complicated by left mastitis associated with febrile neutropenia. Drainage was performed for the left mastitis, and cefepime was initiated. The fever subsided within a few days, but the patient became agitated accompanied by logorrhea. With the exception of mental status, her neurological examination was unremarkable. Due to mild...

Hippocampal Inflammation and Gene Expression Changes in Peripheral Lipopolysaccharide Challenged Mice Showing Sickness and Anxiety-Like Behaviors
We examined the hippocampal inflammation-related gene expression changes over time. The expression of interleukin-1β (Il1b) and tumor necrosis factor α (Tnfa) was rapidly enhanced and sustained until 24 h after LPS administration, whereas the expression of Il6 was transiently induced at approx. 6 h. IL-6-dependent downstream signaling of transducer and activator of transcription 3 (STAT3) was also activated approx. 3-6 h after LPS treatment. The expression of innate immune genes including interferon-induced transmembrane proteins such as interferon-induced transmembrane protein 1 (Ifitm1) and Ifitm3 and complement factor...

Overexpression of CD2/CD27 could inhibit the activation of nitrogen metabolism pathways and suppress M2 polarization of macrophages, thereby preventing brain metastasis of breast cancer
CONCLUSION: In the tumor microenvironment, overexpression of CD2/CD27 inhibited the activation of nitrogen metabolism pathways and suppressed M2 polarization of macrophages, thereby preventing brain metastasis of breast cancer.PMID:37666207 | DOI:10.1016/j.tranon.2023.101768

Management Paradigm of Central Nervous System Metastases in NSCLC: An Australian Perspective
JTO Clin Res Rep. 2023 Jul 26;4(9):100553. doi: 10.1016/j.jtocrr.2023.100553. eCollection 2023 Sep.ABSTRACTLife-prolonging central nervous system active systemic therapies for metastatic NSCLC have increased the complexity of managing brain metastases (BMs). Australian medical oncologists, radiation oncologists, and neurosurgeons discussed the evidence guiding the diverse clinical approaches to the management of BM in NSCLC. The Australian context is broadly applicable to other jurisdictions; therefore, we have documented these discussions as principles with broader applications. Patient management was stratified according...
