The extensor hallucis longus originates from about the middle three fifths of the anterior surface of the fibula, medial to the origin of the extensor digitorum longus, and inserts into the distal phalanx of the great toe. The goal of this study was to examine the insertion of the extensor hallucis longus tendon and thus prepare its first classification in human fetuses.

Fifty spontaneously-aborted human fetuses (26 male, 24 female, 100 lower limbs), aged 18-38 weeks of gestation, were examined.

The classification comprised three types of extensor hallucis longus insertion. The most common was type I (68%), which was characterized by a single tendon that ends as an extensor hood inserting into the dorsal aspect of the base of the distal phalanx of the great toe. The second most frequent was type II (27%), which was characterized by two distal tendons the dominant one ends as an extensor hood inserting into the distal phalanx of the great toe, and the auxiliary inserts separately into the dorsal aspect of the proximal phalanx of the great toe, medial to the insertion of the extensor hallucis brevis tendon. Finally, type III (5%), the least frequent type, was characterized by two distal tendons the dominant one ends as an extensor hood inserting into the distal phalanx of the great toe, and the auxiliary connects to the tendon of the extensor hallucis brevis.

The extensor hallucis longus demonstrates great variability in the approach of its tendon to the foot, at least in fetuses, as indicated by this initial classification.

The article traces this history in the context of the political changes that occurred over six hundred and seventy-two years, giving emphasis to the history of Prague's anatomy departments, its leading anatomists and their discoveries, and historically important anatomical texts published or written in Prague. The article documents the significant contribution to anatomy made in the Czech lands, especially in the nineteenth century and during the calmer periods of the region's turbulent political history.
The use of the Pernkopf atlas of human anatomy in surgery presents ethical challenges due to the author's association with the Nazi regime and the potential depiction of victims of this regime. The atlas was of particular utility to two surgical specialties nerve surgeons and oral and maxillofacial surgeons. The representation of peripheral nerves and complex head and neck anatomy is probably unequaled in any other atlas of anatomy. While the ethical implications of the use of Pernkopf's atlas among nerve surgeons have been previously assessed, this study focuses on the volume dedicated to detailed images of head and neck dissections, and the ethical implications of using this atlas by oral and maxillofacial surgeons.

To (1) assess the role of the Pernkopf atlas in oral and maxillofacial surgeons' current practice and (2) determine whether a proposal of four conditions would provide ethical guidance for use in surgery and education.

Members of three American oral and maxillofacial surgical societies (ACs approach has implications for the future preparation and publication of anatomical atlases and their use.
Amid recent developments and controversy regarding the Pernkopf atlas, a proposal detailing conditions for an ethical approach may provide guidance in surgical planning and education. Furthermore, this approach has implications for the future preparation and publication of anatomical atlases and their use.We synthesized fluoro- and hydroxy-containing octahydro-2H-chromenes by the Prins reaction starting from a monoterpenoid (-)-isopulegol and a wide range of aromatic aldehydes in the presence of the BF3∙Et2O/H2O system acting as both an acid catalyst and a fluorine source. Activity of the produced compounds against the influenza A/Puerto Rico/8/34 (H1N1) virus was studied. The highest activity was demonstrated by fluoro- (11i) and hydroxy-containing (10i) derivatives of 2,4,6-trimethoxybenzaldehyde. The most pronounced virus-inhibiting effect of compounds 10i and 11i was observed at an early stage of infection. These compounds were supposed to be capable of binding to viral hemagglutinin, which is an agreement with data on the effect of compounds 10i and 11i on the viral fusogenic activity as well as by molecular docking studies.We report here the synthesis and characterization of a dual 5-HT7 / 5-HT2 receptor antagonist 3-(4-Fluoro-phenyl)-2-isopropyl-2,4,5,6,7,8-hexahydro-1,2,6-triaza-azulene (4j). 4j is a high affinity 5-HT7 and 5-HT2A receptor ligand having a pKi = 8.1 at both receptors. It behaves as an antagonist in an in vitro functional assay for 5-HT2A and as an inverse agonist in an in vitro functional assay for 5-HT7. In a validated in vivo model for central 5-HT7 activity in rats, blockade of 5-carboxamidotryptamine (5-CT) induced hypothermia, 4j shows efficacy at low doses (ED50 = 0.05 mg/kg, p.o., 1 h) and maximal efficacy was observed at 0.3 mg/kg p.o. with a corresponding plasma concentration of ~27 ng/ml. In a validated in vivo model for central 5-HT2A activity, blockade of 2,5-dimethoxy-4-iodoamphetamine (DOI) induced head-twitches in mice, 4j shows efficacy at low doses with an ED50 = 0.3 mg/kg p.o. Tocilizumab solubility dmso Ex vivo receptor binding studies demonstrate that 4j occupied 5-HT2A receptor binding sites in the frontal cortex of the rat brain with an ED50 in good agreement with the ED50 value for central functional effect mediated by 5-HT2A receptor (ED50 = 0.8 mg/kg, p.o., 1 h).
Allogeneic transplantation immune tolerance is currently a hot research issue and soluble CD83(sCD83) is a novel immunomodulator with great potential in inducing transplantation tolerance.

To investigate the mechanism of the immune tolerance effect of sCD83 on rat liver transplantation.

A rat liver transplantation model was established to study the effects of sCD83 on the expression levels of IL-2, IL-10, and TGF-β in peripheral blood and the mRNA expressions of foxp3, TGF-β, and Indoleamine 2,3-dioxygenase (IDO) in liver. The expression changes of costimulatory molecules CD80, CD86, and MHC-II on the surface of DC cells and the expressions of IDO
DC cell, TGF-β
CD4
T cell, and CD4

Foxp3
T cell were analyzed and compared.

sCD83 alleviated the rejection activity index (RAI) of rat liver transplantation in the early stage, increased the expressions of TGF-β, IL-10 in peripheral blood and the mRNAs of IDO, TGF-β and foxp3 in the transplanted liver, and down-regulated the expressions of MHC-II, CD86, and CD80 in DC cells, resulting in significant increased numbers of tolerogenic TGF-β
