The aim of this study was to evaluate the association of blood lead, mercury, and cadmium concentrations with developmental delays and to explore the association of these concentrations with the health status of children. This study recruited 89 children with developmental delays and 89 age- and sex-matched children with typical development. Their health status was evaluated using the Pediatric Quality of Life (PedsQL) Inventory for health-related quality of life (HRQOL) and the Pediatric Outcomes Data Collection Instrument for function. Family function was also evaluated. Blood lead, mercury, and cadmium concentrations were measured using inductively coupled mass spectrometry. The children with developmental delays had a considerably poorer HRQOL, lower functional performance and family function, and a higher blood lead concentration than those with typical development. The blood lead concentration had a significantly positive association with developmental delays [odds ratio (OR) = 1.54, p < 0.01] in a dose-response manner, and it negatively correlated with PedsQL scores (regression coefficient: -0. 47 to -0.53, p < 0.05) in all the children studied. The higher blood cadmium concentration showed a significantly positive association with developmental delays (OR = 2.24, for >1.0 μg/L vs. <0.6 μg/L, p < 0.05). The blood mercury concentration was not associated with developmental delays and health status.

Excessive accumulation of auxin inhibits protocorm development during germination of Paphiopedilum spicerianum.

Excessive auxin accumulation inhibits protocorm development during germination of Paphiopedilum spicerianum, delaying shoot meristem formation by downregulating boundary genes (CUC1, CUC2, CLV3) and promoting fungal colonization, essential for seedling establishment. Paphiopedilum, possess high horticultural and conservational value. Asymbiotic germination is a common propagation method, but high rates of protocorm developmental arrest hinder seedling establishment.

White-Sutton syndrome (WHSUS) is a rare neurodevelopmental disorder caused by heterozygous variants in the POGZ gene. With slightly over 100 reported cases, the diagnosis of WHSUS remains challenging due to its variable and non-specific clinical features. We report a novel case of WHSUS carrying a heterozygous de novo variant in the POGZ gene and with characteristic clinical features including global developmental delay, autism spectrum disorder, generalised myoclonic epilepsy, hypotonia and distinct dysmorphic features.

Intrauterine growth restriction (IUGR) induced by utero-placental insufficiency (UPI) results in delayed neural development and impaired brain growth. This study investigates the effects of Naringin (Nar) on memory, learning, cholinergic activity, oxidative stress markers, hippocampal CREB/BDNF signal pathway and cell damage in offspring of rats exposed to UPI. Twenty pregnant Wistar rats were randomly assigned to four groups: control, sham surgery, UPI + NS (UPI + normal saline as a vehicle), and UPI + Nar (UPI + Nar at 100 mg/kg/day).

Importance: Intraventricular hemorrhage (IVH) has proven to be a challenging and enduring complication of prematurity. However, its association with neurodevelopment across the spectrum of IVH severity, independent of prematurity, and in the context of contemporary care remains uncertain.
Objective: To evaluate national trends in IVH diagnosis and the association with survival and neurodevelopmental outcomes at 2 years of age.
