Rice Yellow Mottle Virus (RYMV): A Review.

Rice ( spp.) is mostly grown directly from seed and sown on wet or dry seed beds or usually used as transplants on nursery beds. Among all the economically important viral diseases in the world, rice yellow mottle virus (RYMV) is only prevalent in rice-growing countries in Africa.

An Alarming Eastward Front of Cassava Mosaic Disease in Development in West Africa.

Begomoviruses are a major threat to cassava production in Africa. Indeed, during the 1990s, the emergence of a recombinant begomovirus (East African cassava mosaic virus-Uganda, EACMV-Ug) resulted in crop devastation and severe famine in Uganda. In 2023, during a pre-survey of cassava farms at Forécariah, South-West Guinea, 22 samples showing peculiar cassava mosaic disease (CMD) symptoms were collected, and subsequent laboratory analysis confirmed the presence of EACMV-Ug in the samples.

Molecular Diversity and Distribution of Whiteflies () in Cassava Fields Across South West and North Central, Nigeria.

Whitefly (Gennadium, Hemiptera) causes severe damage to cassava plants through excessive feeding on leaves and transmitting viruses, such as (ACMV), (EACMV), and ipomoviruses that cause cassava brown streak disease. Currently, little is known about the molecular diversity and distribution of whitefly species in the major cassava-growing zones of Nigeria. This study aimed to address the knowledge gap by assessing the genetic diversity, distribution, and associated cassava mosaic begomoviruses (CMBs) in whiteflies across South West and North Central, Nigeria.

Knowledge, opinions and experiences of nurses and nursing students in Portugal regarding the use of medical Cannabis.

Background: The opening up of the laws to medicinal cannabis in recent years is a key factor in the growth of this therapy, but there is little information about what nurses know and think about it. The present paper seeks to analyze the knowledge, opinions, and experiences of nurses and nursing students in Portugal regarding the use of cannabis and to understand gender differences.

Methods: A self-completion questionnaire was drawn up and published online.

Constitutive Pleiotrophin Deletion Results in a Phenotype with an Altered Pancreatic Morphology and Function in Old Mice.

Pleiotrophin (PTN) is crucial for embryonic development and pancreas organogenesis as it regulates metainflammation, metabolic homeostasis, thermogenesis, and glucose tolerance. Pleiotrophin deletion is associated with a lipodystrophic phenotype in which adipose tissue plasticity is altered in late life. This study explored the impact of pleiotrophin deletion on pancreatic morphology and function in later life.
