The infection of susceptible plant hosts by single-stranded DNA viruses in the geminivirus group depends on the interaction of host and viral factors for the replication of viral DNA, the expression of viral genes, and the movement of virus throughout the plant. This paper reports that two strains of the geminivirus, beet curly top virus (BCTV) differ in their ability to infect certain ecotypes of Arabidopsis thaliana. Symptoms appeared on susceptible plants approximately 2-3 weeks after inocula

To test the carcinostatic effects of ascorbic acid, we challenged the mice of seven experimental groups with 1.7 x 10(-4) mol high dose concentration ascorbic acid after intraperitoneal administrating them with sarcoma S-180 cells. The survival rate was increased by 20% in the group that received high dose concentration ascorbic acid, compared to the control. The highest survival rate was observed in the group in which 1.7 x 10(-4) mol ascorbic acid had been continuously injected before and afte

Abstract L -Ascorbic acid (vitamin C, AA) exhibits anti-cancer effects with high-dose treatment through the generation of reactive oxygen species (ROS) and selective damage to cancer cells. The anti-cancer effects of L -ascorbic acid are determined by sodium-dependent vitamin C transporter 2 (SVCT-2), a transporter of L -ascorbic acid. In this study, we demonstrate that L -ascorbic acid treatment showed efficient anti-cancer activity in cell lines with high expression levels of SVCT-2 for a grad

Tomato leaf curl New Delhi virus (ToLCNDV) is a bipartite begomovirus affecting tomato cultivation on the Indian subcontinent. Recently, however, a new strain of the virus, named ToLCNDV-ES, has spread to Mediterranean countries such as Spain, Italy, and Tunisia, and occurred in Cucurbita crops, causing economic damage. Although ToLCNDV is spread by the sweet potato whitefly (Bemisia tabaci), like other begomoviruses, it has not been clear how ToLCNDV suddenly spread from the Indian subcontinent

STUDY DESIGN: Case report. OBJECTIVE: To illustrate a rare cause of thoracic spinal cord compression, its diagnosis, and its management. SUMMARY OF BACKGROUND DATA: Asymptomatic vertebral hemangiomas are common, but extraosseous extension causing spinal cord compression with neurologic symptoms is rare, and few cases appear in the English-language literature. METHOD: A previously asymptomatic 63-year-old man sought medical attention for acute back pain and thoracic myelopathy of 6 week's duratio

Pear black necrotic leaf spot (PBNLS) is a disease of pears caused by capillovirus-like particles, which can be observed under the electron microscope. The disease was analyzed by Western blot analysis with antisera raised against apple stem grooving virus (ASGV) coat protein. cDNAs covering the entire genome were synthesized by RT-PCR and RACE using RNA isolated from Chenopodium quinoa infected with sap extracted from pear leaves carrying black necrotic spot disease. The complete genome sequenc

Tomato yellow leaf curl virus (TYLCV) dispersed across different countries, specifically to subtropical regions, associated with more severe symptoms. Since TYLCV was first isolated in 1931, it has been a menace to tomato industrial production worldwide over the past century. Three groups were newly isolated from TYLCV-resistant tomatoes in 2022; however, their functions are unknown. The development of machine learning (ML)-based models using characterized sequences and evaluating blind predicti

Oxaliplatin is a platinum-based anticancer drug used to treat metastatic colorectal, breast, and lung cancers. While oxaliplatin kills cancer cells effectively, it exhibits several side effects of varying severity. Neuropathic pain is commonly experienced during treatment with oxaliplatin. Patients describe symptoms of paresthesias or dysesthesias that are triggered by cold (acute neuropathy), or as abnormal sensory or motor function (chronic neuropathy). In particular, we found that aluminum le
