Malaria is caused by protozoan parasites of the genus Plasmodium and remains a global health concern. The parasite has a highly adaptable life cycle comprising successive rounds of asexual replication in a vertebrate host and sexual maturation in the mosquito vector Anopheles. Genetic manipulation of the parasite has been instrumental for deciphering the function of Plasmodium genes.

The brainstem plays a vital role in regulating blood pressure, and disruptions to its neural pathways have been linked to hypertension. However, it remains unclear whether subtle microstructural changes in the brainstem are associated with an individual's blood pressure status. This exploratory, cross-sectional study investigated the relationship between brainstem microstructure, myelination, and hypertensive status in 116 cognitively unimpaired adults (aged 22-94 years).

Positional downbeat nystagmus (pDBN) is a common finding in dizzy patients, with etiologies ranging from benign paroxysmal positional vertigo (BPPV) to central vestibular lesions. Although peripheral pDBN often presents with distinct clinical features that differentiate it from BPPV, diagnosing its etiology can be challenging. A thorough clinical evaluation, including the physical characteristics of the nystagmus, response to positional maneuvers, and neurological findings, is often sufficient to diagnose conditions that provoke pDBN such as anterior canal BPPV, atypical posterior canal BPPV, and central causes.

Genetic diversity is crucial to secure the survival and sustainability of ecosystems. Given anthropogenic pressure, as well as the projected alterations connected with the level and circulation of water, riparian forests are of particular concern. In this paper, we assessed the genetic variation of black poplar - one of the keystone tree species of riverine forests.

From the Department of Neuroradiology (G.B., N.H., F.D.v.D., A.B., Z.K.), University Hospital Zürich, Zürich, Switzerland.
Background And Purpose: Whether differences in the O-methylguanine-DNA methyltransferase () promoter methylation status of glioblastoma (GBM) are reflected in MRI markers remains largely unknown. In this work, we analyze the ADC in the perienhancing infiltration zone of GBM according to the corresponding status by using a novel distance-resolved 3D evaluation.
Materials And Methods: One hundred one patients with wild-type GBM were retrospectively analyzed.
