The cell length of the short siblings of dividing pairs formed in the absence of replication by two strains of Escherichia coli, OV-25-9 [dnaA46 wee(Am)] and OV-25-10 [dnaA46 wee(AM) supF] was measured. In the presence of Wee, the length of these cells increased to those values expected for newborn wild-type cells growing under similar conditions. In its absence, cell length remained at values near the minimum unit length possible for newborn cells. Our results show that both cell elongation and the action of Wee are independent of DNA replication, being compatible with the role proposed for Wee in coordination between cell elongation and division.

Background: The Japanese eel (Anguilla japonica) holds significant economic value in East Asia, but limitations in understanding its reproductive biology have hindered advancements in artificial breeding techniques. Previous research has primarily focused on conserved sex differentiation genes, offering limited insights into the broader molecular mechanisms driving gonadal development and sexual dimorphism. To address these limitations, this study aims to investigate key genes and pathways involved in gonadal development through a comprehensive transcriptomic analysis of male and female eel gonads.

Objective: This study aims to investigate the correlation between the development of diabetic retinopathy (DR) and the changes in corneal sub-basal nerve plexus (SNP) and corneal dendritic cells (DCs).
Methods: 58 patients with type 2 diabetes mellitus (T2DM) and 30 age- and sex-matched healthy participants underwent assessment of the corneal nerve. The DR group was divided into no diabetic retinopathy (NDR) and 29 eyes with mild to moderate non-proliferative diabetic retinopathy (NPDR).

We previously demonstrated that the inability of primary endothelial cilia to sense fluid shear stress can lead to nitric oxide (NO) deficiency and cause hypertension (HTN). Decreased biosynthesis of NO contributes to cerebral amyloid angiopathy in Alzheimer's disease (AD) patients through increased deposition of amyloid beta (Aβ). However, the molecular mechanisms underlying the pathogenesis of HTN and AD are incompletely understood.

Both acute kidney injury and chronic kidney disease are risk factors for many outcomes of gastrointestinal bleeding (GIB). These are associated with higher mortality, longer hospitalisation, and greater need for transfusion in case of overt GIB. Our study aimed to further evaluate the role of kidney function in several clinical outcomes of GIB patients.

Twenty-nine GRAS genes were identified in passion fruit, the N-terminal regions and 3D (three-dimensional) structures were closely related with their tissue-specific expression patterns. Candidate PeGRASs for enhancing stress resistance were identified. Passion fruit (Passiflora edulis Sims) is a tropical fruit crop with significant edible and ornamental value, but its growth and development are highly sensitive to environmental conditions.
