This study aimed to describe the morphological alterations that occur in the midgut and mesentery over time during the herniated phase of the midgut. The primary loop, a single hairpin-shaped loop, becomes recognizable at Carnegie stage (CS) 16. This loop projects toward the umbilical cord and subsequently gives rise to four secondary loops in the midgut of human embryos.

Since their origin, sauropodomorphs have undergone numerous anatomical changes from small and bipedal early sauropodomorphs towards massive-bodied and quadrupedal sauropods. However, the timing of these changes in the evolution of the group is unclear. Here, we describe the appendicular skeleton of the early diverging eusauropod Bagualia alba from the late Early Jurassic of Patagonia, Argentina, and conduct a morphological disparity analysis based on a phylogenetic dataset of Sauropoda.

Studying avian embryology necessitates reliable and precise staging tables-descriptions of embryonic features appearing during development that are used to approximate the extent of embryonic development from fertilisation to hatching. Staging tables for waterfowl (Anseriformes) have previously been established based on morphological features from fertilisation to approximately 10 days before hatching. Embryonic changes over the final 10 days of pre-hatching development have also been documented and proposed as useful staging criteria.

Plant-growth-promoting microorganisms are extensively studied and employed as alternatives to toxic agrochemicals to enhance plant health. However, one of the main concerns regarding their use is their limited capacity to colonize plant tissues after initial application. Understanding the molecular mechanisms involved during plant colonization could help to develop strategies to improve the efficacy of beneficial microbes in the field.

Intrinsic biophysical and morphological features are essential for the label-free identification of different cell types. Indeed, apart from object size, density could represent a key parameter for single-cell analysis. However, the measurement of such a parameter is challenging.
