Tomato yellow leaf curl Guangdong virus (TYLCGdV), a monopartite begomovirus first identified in 2004, remains poorly characterised. In this study, we demonstrate that TYLCGdV associates with a betasatellite, TYLCGdB, and the βC1 protein encoded by TYLCGdB is essential for symptom development. We also explore the role of TYLCGdV C4 protein by generating a C4-deficient infectious clone (TYLCGdV), revealing a dynamic role for TYLCGdV C4.

A series of Dehydroabietylamine (DHAA) C-ring Schiff derivatives, L3-L20, were synthesized and their in vitro cytotoxic activity against the human tumor cell lines cervix HeLa, breast MCF-7, lung A549, liver HepG2, and the nonmalignant cell line umbilical vein HUVEC was investigated. Most of the compounds showed varying degrees of anticancer activity against HeLa cell lines while demonstrating lower toxicity to normal HUVEC cells compared to DHAA and doxorubicin (DOX), especially compound L19, which not only enhanced the anticancer activity of DHAA, but also significantly reduced the toxicity to normal cells, achieving a selectivity index (SI) 118 times higher than that of DHAA and 245 times higher than that of DOX. In addition, compound L19 induced apoptosis in HeLa cells in a dose-dependent manner and arrested the cell cycle in S phase.

Department of Medical Laboratory Sciences, College of Medicine and Health Sciences, Wollo University, Dessie, Ethiopia.
Background: The increased occurrence of malaria among Africa's displaced communities poses a new humanitarian problem. Understanding malaria epidemiology among the displaced population in African refugee camps is a vital step for implementing effective malaria control and elimination measures. As a result, this study aimed to generate comprehensive and conclusive data from diverse investigations undertaken in Africa.

Background: Aedes aegypti is the primary vector of dengue, chikungunya, and Zika viruses in Colombia. Various insecticides, including pyrethroid, organophosphate, and carbamate insecticides; growth regulators; and biological insecticides, such as Bacillus thuringiensis var. israelensis, have been used to control Ae.

Department of Biomedical and Biotechnological Sciences, Division of Medical Biochemistry, University of Catania, Catania, Italy.
Background: Clonal myeloproliferation and fibrotic transformation of the bone marrow (BM) are the pathogenetic events most commonly occurring in myelofibrosis (MF). There is great evidence indicating that tumor microenvironment is characterized by high lactate levels, acting not only as an energetic source, but also as a signaling molecule.
Methods: To test the involvement of lactate in MF milieu transformation, we measured its levels in MF patients' sera, eventually finding a massive accumulation of this metabolite, which we showed to promote the expansion of immunosuppressive subsets.
