    mTORC2 promotes pancreatic cancer progression and parp inhibitor resistance

    CHIWEN BU1,2, LIGANG ZHAO1, LISHAN WANG1, ZEQIAN YU1, JIAHUA ZHOU1,*

    Oncology Research, Vol.31, No.4, pp. 495-503, 2023, DOI:10.32604/or.2023.029309

    Abstract Pancreatic cancer is one of the most aggressive cancers with a median survival time of less than 5 months, and conventional chemotherapeutics are the main treatment strategy. Poly(ADP-ribose) polymerase (PARP) inhibitors have been recently approved for BRCA1/2-mutant pancreatic cancer, opening a new era for targeted therapy for this disease. However, most pancreatic cancer patients carry wild-type BRCA1/2 with resistance to PARP inhibitors. Here, we reported that mammalian target of rapamycin complex 2 (mTORC2) kinase is overexpressed in pancreatic cancer tissues and promotes pancreatic cancer cell growth and invasion. Moreover, we found that knockdown of the More > Graphic Abstract

    Targeting DNA repair for cancer treatment: Lessons from PARP inhibitor trials

    DHANYA K. NAMBIAR1, DEEPALI MISHRA2, RANA P. SINGH2,3,*

    Oncology Research, Vol.31, No.4, pp. 405-421, 2023, DOI:10.32604/or.2023.028310

    Abstract Ionizing radiation is frequently used to treat solid tumors, as it causes DNA damage and kill cancer cells. However, damaged DNA is repaired involving poly-(ADP-ribose) polymerase-1 (PARP-1) causing resistance to radiation therapy. Thus, PARP-1 represents an important target in multiple cancer types, including prostate cancer. PARP is a nuclear enzyme essential for single-strand DNA breaks repair. Inhibiting PARP-1 is lethal in a wide range of cancer cells that lack the homologous recombination repair (HR) pathway. This article provides a concise and simplified overview of the development of PARP inhibitors in the laboratory and their clinical More > Graphic Abstract

    “Treat-Repair-Treat”: Management of Left Main Coronary Compression by a Pulmonary Artery Aneurysm in a Patient with Atrial Septal Defect and Significant Pulmonary Hypertension

    Andrei George Iosifescu1,2,*, Roxana Enache1,3, Ioana Marinică4, Corina Radu2, Vlad Anton Iliescu1,2

    Congenital Heart Disease, Vol.18, No.1, pp. 67-72, 2023, DOI:10.32604/chd.2023.026598

    Abstract Left main coronary compression syndrome (LMCS) may complicate pulmonary artery aneurysms (PAA), usually developed in the context of pulmonary arterial hypertension (PAH). We report the case of a 51-year-old female patient with an atrial septal defect (unsuitable for device closure) complicated by a PAA generating a 90% left main stenosis. The significant PAH held us back from immediate surgery. After specific dual PAH-targeted therapy (sildenafil and bosentan), the atrial septal defect could be closed with a unidirectional valved patch; the PAA-induced LMCS was treated by reductive arterioplasty. The postoperative course was uneventful. Follow-up showed clinical More > Graphic Abstract

    Interventricular Septal Hematoma after Congenital Cardiac Defects Repair at a Single Institution

    Yuan Hu1, Xiaohui Yang2, Jie Dong3, Peng Huang2, Jinwen Luo2, Guangxian Yang2, James D. St. Louis4, Xicheng Deng2,*

    Congenital Heart Disease, Vol.17, No.6, pp. 687-695, 2022, DOI:10.32604/chd.2022.024333

    Abstract Background: Interventricular septal hematoma is a rare complication after congenital cardiac repair. The management varies according to the literature. We present our experience with this rare complication. Methods: Echocardiography database were reviewed with the term ‘‘hematoma’’ or “hypoechoic mass” for patients who underwent congenital heart surgery from January 2018 to December 2021 at our institution to identify potential interventricular septal hematoma cases. Relevant data of the patients identified were collected. Focus was put on the presentation, management, outcomes according to patent medical charts and serial echocardiographic report data. Results: In total, there were 5 patients included. The… More > Graphic Abstract

    Appropriate Heart Rate in a Patient with Repaired Tetralogy of Fallot

    Aya Miyazaki1,2,*, Hideki Uemura2, Yasuyo Takeuchi3, Junya Tomida4, Yasuo Ono1, Yoshifumi Fujimoto1, Norie Mitsushita1, Akio Ikai1

    Congenital Heart Disease, Vol.17, No.6, pp. 647-652, 2022, DOI:10.32604/chd.2022.021837

    Abstract Appropriate heart rate in a failing pulmonary ventricle remains unknown, particularly in congenital heart disease with unique hemodynamics. A 71-year-old male with repaired tetralogy of Fallot and a pacemaker for a sinus node dysfunction suffered from heart failure symptoms with preserved left ventricular function. Simply changing the pacemaker’s lower rate from 60 to 75 bpm, New York Heart Association classification improved from III to II, and hemodynamic parameters drastically improved. We regarded this case as informative. Appropriate heart rate could be higher in congenital patients with failing right and non-failing left ventricles than in adults More > Graphic Abstract

    Development of a prognostic signature for esophageal cancer based on a novel 7-DNA damage repair genes signature

    BIOCELL, Vol.46, No.12, pp. 2601-2613, 2022, DOI:10.32604/biocell.2022.021300

    Abstract Esophageal cancer (EC) was an aggressive malignant neoplasm characterized by high morbidity and poor prognosis. Identifying the changes in DNA damage repair genes helps to better understand the mechanisms of carcinoma progression. In this study, by comparing EC samples and normal samples, we found a total of 132 DDR expression with a significant difference. Moreover, we revealed higher expression of POLN, PALB2, ATM, PER1, TOP3B and lower expression of HMGB1, UBE2B were correlated to longer OS in EC. In addition, a prognostic risk score based on 7 DDR gene expression (POLN, HMGB1, TOP3B, PER1, UBE2B,… More >

    CLEC: Combination Locality Based Erasure Code for Permissioned Blockchain Storage

    Jiabin Wu1,3, Boai Yang2, Yang Liu1, Fang Liu3,*, Nong Xiao1, Shuo Li4

    CMC-Computers, Materials & Continua, Vol.73, No.3, pp. 5137-5150, 2022, DOI:10.32604/cmc.2022.028305

    Abstract Building a new decentralized domain name system based on blockchain technology is helping to solve problems, such as load imbalance and over-dependence on the trust of the central node. However, in the existing blockchain storage system, the storage overhead is very high due to its full-replication data storage mechanism. The total storage consumption for each block is up to O(n) with n nodes. Erasure code applied to blockchains can significantly reduce the storage overhead, but also greatly lower the read performance. In this study, we propose a novel coding scheme for blockchain storage, Combination Locality… More >

    Construction of Customized Bio Incubator and Designing of Tailored Scaffolds for Bone Tissue Engineering from Laboratory Scale Up to Clinical Scale

    Soliman Abdalla1,2,*, Shiref Kandil2

    Journal of Renewable Materials, Vol.10, No.11, pp. 2699-2716, 2022, DOI:10.32604/jrm.2022.022334

    Abstract In order to obtain larger, clinical-scale and practical-scale bone grafts, we have designed both tailored scaffolds and tailored bio incubator with optimal bio-production characteristics. Using DIC files to Simpleware Scan-IP (Simple-ware-exeter United Kingdom), we have digitally reconstructed segmental additive bone-tissue in order to perform images processing. Both hydroxyapatite and tannin composites have been used in order to get the final bone modules combined for retexturing of segmental bone defect. We have found that sectioning of bone segment deficiency reorganizations into well disk-shaped design permits one to standardize the cell culture and seeding protocol, to get More >

    Congenital Heart Disease, Vol.17, No.3, pp. 245-267, 2022, DOI:10.32604/chd.2022.021778

    Abstract Background: Studies on predictors of health-related quality of life (HRQOL) in pediatric patients with cyanotic heart disease who are waiting for the next stage and those who have undergone total repair are scarce. Therefore, we aimed to identify such predictors in children who received the modified Blalock–Taussig shunt (MBTS) and those who underwent total repair. Methods: In this historical cohort and concurrent follow-up study, data of children who underwent MBTS at the age of 0–3 years between January 2005 and December 2016 at a super-tertiary care hospital in Southern Thailand were obtained. Children who were alive… More > Graphic Abstract
