Early functional and morphological changes of calf muscles in delayed onset muscle soreness (DOMS) assessed with 7T MRI

Rafael Heiss, Svenja A. Hoeger, Michael Uder, Thilo Hotfiel, Jannis Hanspach, Frederik B. Laun, Armin M. Nagel, Frank W. Roemer

Summary: This study utilized 7 Tesla magnetic resonance imaging (MRI) to assess morphological and functional changes in skeletal muscle during exercise-induced delayed onset muscle soreness (DOMS). The results showed significant alterations in T2 signal intensity and T2 values immediately after exercise and 60 hours later. These findings suggest the potential use of ultra-high field MRI in sports medicine to monitor microstructural muscle damage and guide appropriate therapeutic strategies.

Development of the human primary and secondary jaw joints

E. M. Fernandez-Rubio, R. J. Radlanski

Summary: This study investigates the development of the primary and secondary temporomandibular joints in humans, focusing on their coexistence and subsequent separation. The findings reveal that both joints develop simultaneously and remain connected for over 6 weeks before separating at around the 18th to 24th week. Understanding the precise timing and functional movements involved in the development of these joints is crucial for comprehending the overall development of the temporomandibular joint.

Clinical anatomy of the spina musculi recti lateralis: A frequently overlooked variation of the greater wing of the sphenoid

Denise Bonente, Virginia Barone, Vitaliano Francesco Muzii, Sara Ottolenghi, Miriam Durante, Sandra Bracco, Claudio Nicoletti, Eugenio Bertelli

Summary: This study characterizes the morphology and topography of the spina musculi recti lateralis (SMRL) and compares it to known bony landmarks. The results show that the SMRL is a process of the sphenoidal orbital plate and serves as a reliable landmark for the insertion of the tendinous ring and lateral rectus. This is an important variation for orbital surgeons to be aware of.

Effects of Tulp4 deficiency on murine embryonic development and adult phenotype

Roland Jaeger, Stefan H. Geyer, Anoop Kavirayani, Mate G. Kiss, Elisabeth Waltenberger, Thomas Ruelicke, Christoph J. Binder, Wolfgang J. Weninger, Robert Kralovics

Summary: Genetically engineered mouse models have the potential to uncover basic biological processes and provide mechanistic insights into human disease pathogenesis. This study reveals the impact of TULP4 deficiency on embryonic development and the clinical characteristics of myeloproliferative neoplasms. It also suggests the potential role of TULP4 in organ system abnormalities and obesity-related phenotypes.

Testing the reliability of the rearticulation of osteological primate pelves in comparative morphological studies

Nicole Torres-Tamayo, Todd C. Rae, Eishi Hirasaki, Lia Betti

Summary: By comparing virtual and actual rearticulated pelvic models, this study found that rearticulating pelvic bones does not substantially affect the biological signal in comparative morphological studies. However, species with wide pubic gaps should be preferentially included in these studies.

Prostate-specific antigen: An unfamiliar protein in the human salivary glands

Michela Isola, Cristina Maxia, Daniela Murtas, Joergen Ekstroem, Raffaella Isola, Francesco Loy

Summary: The presence and distribution of prostate-specific antigen (PSA) in the salivary glands were investigated. PSA expression was found in serous secretory acini and striated ducts of the parotid and submandibular glands. Immunocytochemical analysis revealed PSA localization in the cytoplasmic vesicles and rough endoplasmic reticulum, as well as in the acini lumen. These findings support the involvement of salivary glands in the secretion of PSA, possibly through minor regulated secretory or constitutive-like secretory pathways.

Comparing age- and bone-related differences in collagen fiber orientation: A case study of bats and laboratory mice using quantitative polarized light microscopy

Tobin Lee Hieronymus, David A. Waugh, Hope C. Ball, Christopher J. Vinyard, Alex Galazyuk, Lisa Noelle Cooper

Summary: This study compares the changes in collagen fiber orientations (CFO) in wing bones of big brown bats and laboratory mice. The results show that big brown bats have unique patterns of CFO, with longitudinally arranged and more anisotropic bone tissue in older individuals. In contrast, mice did not show consistent age-related changes in bone tissue. This study provides a methodological foundation for future quantitative evaluation of bone tissue architecture in different mammals.

Testicular regression and recrudescence in the bat Eptesicus furinalis: Morpho-physiological variations and hormonal signaling pathways

Larissa Mayumi Bueno, Emilia M. Soares, Juliana F. Ferraz, Cornelio S. Santiago, Manuela Tosi Comelis-Martins, Sebastiao Roberto Taboga, Eliana Morielle-Versute, Mateus Rodrigues Beguelini

Summary: This study analyzed the morphological variations and hormonal control of the testes of Eptesicus furinalis bats during their reproductive cycle. The results showed that the regression and recrudescence of the testes are regulated by pituitary, androgen, and estrogen hormones through the activation and cross signaling of certain receptors in Sertoli and Leydig cells. Testicular regression is activated by a decrease in androgen receptor expression in Sertoli cells, while testicular recrudescence is initiated by an increase in luteinizing hormone receptor expression in Leydig cells, as well as androgen and follicle-stimulating hormone receptor expression in Sertoli cells.

Bone histology supports gregarious behavior and an early ontogenetic stage to Decuriasuchus quartacolonia (Pseudosuchia: Loricata) from the Middle-Late Triassic of Brazil

Brodsky Dantas Macedo de Farias, Julia Brenda Desojo, Ignacio Alejandro Cerda, Ana Maria Ribeiro, Jorge Ferigolo, Thiago Carlisbino, Cesar Leandro Schultz, Bianca Martins Mastrantonio, Marina Bento Soares

Summary: This study examines the osteohistology of Decuriasuchus quartacolonia, a fossil reptile from Brazil, and infers its growth patterns and ontogeny. The findings suggest an early ontogenetic stage for all specimens studied and provide evidence of gregarious behavior in Decuriasuchus. Additionally, it is proposed that Decuriasuchus may represent an earlier growth stage of Prestosuchus chiniquensis.
