Sequential STING and CD40 agonism drives massive expansion of tumor-specific T cells in liposomal peptide vaccines.

The clinical use of cancer vaccines is hampered by the low magnitude of induced T-cell responses and the need for repetitive antigen stimulation. Here, we demonstrate that liposomal formulations with incorporated STING agonists are optimally suited to deliver peptide antigens to dendritic cells in vivo and to activate dendritic cells in secondary lymphoid organs. One week after liposomal priming, systemic administration of peptides and a costimulatory agonistic CD40 antibody enables ultrarapid expansion of T cells, resulting in massive expansion of tumor-specific T cells in the peripheral blood two weeks after priming.

Assessment of the internal connection of an angled screw channel system.

Statement Of Problem: The angled screw channel (ASC) design has been well accepted for implant prostheses. However, investigation into the behavior of the ASC connection is sparse.

Antitumor Activity of the PD-1/PD-L1 Inhibitor SCL-1 in Various Mouse Tumor Models.

Background/aim: Immune checkpoint blockade has achieved great success as a targeted immunotherapy for solid cancers. However, small molecules that inhibit programmed death 1/programmed death ligand 1 (PD-1/PD-L1) binding are still being developed and have several advantages, such as high bioavailability. Previously, we reported a novel PD-1/PD-L1-inhibiting small compound, SCL-1, which showed potent antitumor effects on PD-L1 tumors.

A Narrative Review of the Role of Immunotherapy in Metastatic Carcinoma of the Colon Harboring a BRAF Mutation.

Patients affected by metastatic carcinoma of the colon/rectum (mCRC) harboring mutations in the BRAF gene (MBRAF) respond poorly to conventional therapy and have a prognosis worse than that of patients without mutations. Despite the promising outcomes of targeted therapy utilizing multi-targeted inhibition of the mitogen-activated protein kinase (MAPK) signaling system, the therapeutic efficacy, especially for the microsatellite stable/DNA proficient mismatch repair (MSS/PMMR) subtype, remains inadequate. Patients with MBRAF/mCRC and high microsatellite instability or DNA deficient mismatch repair (MSI-H/DMMR) exhibit a substantial tumor mutation burden, suggesting a high probability of response to immunotherapy.

Comparison of Cell-death Kinetics of Recombinant Methioninase (rMETase)-treated Cancer and Normal Cells: Only Cancer Cells Undergo Methionine-depletion Catastrophe at Low rMETase Concentrations.

Background/aim: Methionine addiction, known as the Hoffman effect, makes cancer cells more sensitive to methionine restriction than normal cells. However, the long-term effects of methionine restriction on cancer and normal cells have not been thoroughly studied.

Materials And Methods: HCT-116 human colorectal-cancer cells and Hs27 normal skin fibroblasts were treated with 0-8 U/ml of recombinant methioninase (rMETase) for 12 days.

Altering phosphorylation of dystrophin S3059 to attenuate cancer cachexia.

Aims: Cancer cachexia affects up to 80 % of patients with advanced cancer and accounts for >20 % of all cancer-related deaths. Sarcolemmal localization of dystrophin, a key protein within the dystrophin-glycoprotein complex (DGC), is perturbed in multiple muscle wasting conditions, including cancer cachexia, indicating a potential role for dystrophin in the maintenance of muscle mass. Strategies to preserve dystrophin expression at the sarcolemma might therefore combat muscle wasting.

Comparative analysis of functional end-to-end and end-to-side anastomosis in laparoscopic right hemicolectomy for colon cancer.

Background: Despite advancements in laparoscopic right hemicolectomy for right-sided colon cancer, the choice between functional end-to-end anastomosis and end-to-side anastomosis remains a topic of debate. This study aimed to compare these 2 techniques in terms of postoperative complications and disease-free survival.

Methods: This retrospective analysis included 1,202 patients who underwent laparoscopic right hemicolectomy for nonmetastatic colon cancer at Samsung Medical Center between January 2007 and February 2016.

Evaluation of ChatGPT-4 for the detection of surgical site infections from electronic health records after colorectal surgery: A pilot diagnostic accuracy study.

Sciatic hernia, a rare type of pelvic floor hernia, presents significant diagnostic and therapeutic challenges. We report the first totally extraperitoneal (TEP) repair of a sciatic hernia, which was performed in a 63-year-old woman who presented with vomiting and poor dietary intake. Computed tomography revealed a strangulated femoral hernia and an incidental herniation of the sigmoid colon through the right sciatic foramen.

Common Iliac Vein Injury Due to a Rectal Impalement Wound Treated Conservatively.

BACKGROUND Iliac vein injuries usually require surgical intervention due to their high mortality rates.
