Summary: The Gondwana formations in Pranhita-Godavari Valley in central India contain fossils of early dinosaurs, providing important information for understanding dinosaur assemblages. Through detailed description of the anatomy of an early dinosaur, it is found that the dispersal of early sauropodomorph dinosaurs between the Southern Hemisphere and Europe may have occurred earlier than previously inferred.

Summary: During anatomical dissection, a unilateral duplication of the uterine artery was found in a Korean female cadaver. The duplication included two branches supplying different parts of the uterus, with the left uterine artery having a smaller diameter. This variation is noteworthy and can have implications for surgical procedures.

Summary: A novel image processing method based on scanning electron microscopy images and ellipse fitting is developed to quantitatively characterize the shape and orientation of enamel prisms. Color coded orientation maps provide quick insight into the microstructure of enamel and allow for statistical analysis of prism arrangement. This method contributes to the quantitative investigation of prism arrangement in dentistry research and evolution biology.

Summary: The aim of this study was to determine the location, variations, and connections of the zygomaticofacial foramina. A total of 171 zygomatic bones of unknown gender were examined. The number of zygomaticofacial foramina was found to be 299, with single, double, three, four, five, and six foramina being present in different proportions. Additionally, connections with the zygomatico-orbital and zygomaticotemporal foramina were observed. The distances between the zygomaticofacial foramen and various anatomical landmarks were also measured.

Summary: This study aimed to characterize the origin and course of the zygomaticus major muscle (Zmj) and its topographic relationships with the nasal ala, tragus, philtrum, and lateral canthus. By combining dissection with image analysis, the study provided positional information for predicting the location of the Zmj origin and course, as well as its related structures.

Summary: This study demonstrates the reliability and validity of three-dimensional freehand ultrasound in assessing the muscle structure and volume of the lumbar multifidus. The measurements obtained using this technique showed a moderately good correlation with magnetic resonance imaging, although the volume measured by three-dimensional freehand ultrasound was systematically smaller. These findings are significant for research and clinical treatment of patients with low back pain.

Summary: Capturing data on fossorial vertebrates is challenging due to limited access to the subterranean environment. However, indirect information from preserved specimens and reports can provide insights into their biology and behavior. Studying the adaptations and evolutionary strategies of these animals is of great importance.

Summary: Juniper species contain abundant compounds that have various applications and protect the plants from stress. This study investigated the cytochemical and histochemical traits of Juniperus seravschanica, revealing the composition and distribution of different compounds in leaves, stems, and female cones. The high levels of various compounds in the female cones contribute to their resistance and medicinal role.

Summary: This study found that Troponin-I (TnI) is expressed in future gut cells and regulates gastrulation in sea urchin embryos. Blocking the function of TnI inhibited invagination, indicating its involvement in nonmuscular actin-myosin interactions. The results suggest a new evolutionary and functional scenario of the Troponin system in nonmuscular cell behaviors.

Summary: This study investigated the involvement of dorsal and ventral subdivisions of the Inferior Frontal Occipital Fasciculus (IFOF) in response inhibition tasks, revealing that the integrity of both branches in the left hemisphere were associated with inhibitory performance, especially when the signals to stop were meaningful and presented as written words. The results suggest that the left dorsal IFOF is implicated in the domain-general control of visually-guided behavior, while the left ventral branch might interface with the semantic system to support action control based on meaning.

Summary: Physical exercise, particularly coordinative exercises, can induce changes in brain structure that are beneficial for brain health. This study demonstrated that engaging in regular physical exercise breaks, with a focus on juggling tasks, led to alterations in brain structures involved in visuomotor processes related to hand and arm movements.

Summary: This study aimed to morphologically differentiate the masticatory muscles in black-tip sharks and shovelnose ray fish. Through anatomical dissection, the position and function of each muscle were identified. Different muscles were involved in the feeding process of each species, with adductor mandibulae and intermandibularis muscles responsible for closing the mouth and muscles like levator palatoquadrati, levator hyomandibulae, and coracomandibularis contributing as well.

Summary: New material of the procolophonid Libognathus sheddi from the Upper Triassic Cooper Canyon Formation in West Texas reveals new information about its cranial anatomy. Through phylogenetic analysis, this study demonstrates that Libognathus is a highly derived leptopleuronine procolophonid closely related to other southwest USA Revueltian leptopleuronines.

Summary: In this study, the diffusible, iodine-based contrast-enhanced computed tomography (DiceCT) method was used to preserve three-dimensional fascicle orientation and tortuosity across a functional comparative sample, exploring the relationship between feeding ecology and masticatory muscle microanatomy. The results show that fascicle properties derived from digital analyses generally agree with those measured from gross-dissected conspecifics. These findings highlight the importance of muscle architecture in relation to dietary ecology and suggest that future research should explore this relationship across larger samples.

Summary: Patients with Anorexia Nervosa and athletes have similar pituitary gland structure alterations, where absolute and relative undernutrition lead to a decreased anterior pituitary gland volume. This alteration can be reversed with weight gain and is correlated with low bodyweight and blockade of the hypothalamic-pituitary-gonadal axis.
