Multifidus muscles maintain the stability of the lumbar spine and play a crucial role in the pathogenesis of nonspecific lower back pain. Previous studies have shown that electroacupuncture (EA) can relieve the symptoms of low back pain and reduce injury to the lumbar multifidus muscles. In this study, a rat model of lumbar multifidus muscle injury was established by 0.05% bupivacaine injection and subsequently treated with EA at bilateral "Weizhong" (BL40) acupoints. Disruption of the function and structure of multifidus muscles, increased cytosolic Ca2+ in multifidus myocytes, and reduced mitochondrial fission and ATP production were observed in the model group. Additionally, increased expression of the mitochondrial calcium uniporter (MCU) promoted mitochondrial reuptake of Ca2+ , reversing the excessive increase in cytoplasmic Ca2+ . However, the excessive increase in MCU not only aggravated the increased cytoplasmic Ca2+ but also decreased the expression of the mitochondrial division proteins dynamin-related protein 1 (Drp1) and mitochondrial fission factor (MFF). EA inhibited the overexpression of MCU, promoted mitochondrial reuptake of Ca2+ , and reversed cytosolic Ca2+ overload. Furthermore, EA regulated the expression of the mitochondrial fission proteins Drp1 and MFF and promoted the production of ATP, helping the recovery of mitochondrial function after multifidus injury. Therefore, EA can protect against bupivacaine-induced mitochondrial dysfunction, possibly by attenuating MCU overexpression in the inner mitochondrial membrane and reducing Ca2+ overloading in muscle cells, thereby protecting mitochondrial function and maintaining the normal energy demand of muscle cells.腰多裂肌维持腰椎的稳定性，在非特异性下腰痛发病中发挥重要作用。前期研究表明电针(EA)能够缓解腰痛症状，减轻腰多裂肌损伤。本研究通过0.05%布比卡因注射制备腰多裂肌损伤大鼠模型，并在“委中”(BL40)穴进行EA干预。结果显示，模型组多裂肌的结构和功能异常，肌细胞胞浆Ca2+ 增加，线粒体分裂和ATP的产生能力降低。本研究还发现一定程度的线粒体钙单向转运体(MCU)增加，可促使线粒体重摄取Ca2+ ,从而逆转胞浆Ca2+ 过度升高；而MCU的过度增加不仅会加剧胞浆Ca2+ 增高，还会减少线粒体分裂蛋白Drp1和MFF。EA干预后可以抑制MCU的过度表达，促进线粒体重摄取Ca2+ ,逆转胞浆Ca2+ 超载。此外，EA还可以调控线粒体分裂蛋白Drp1和MFF的表达，促进ATP的产生，这有利于多裂肌损伤后线粒体功能的恢复。因此，我们得出结论，EA对布比卡因引起的线粒体功能障碍具有保护作用，这些保护机制可能是通过抑制线粒体内膜的MCU的过度表达，减少肌细胞Ca2+ 超载现象，保护线粒体功能，从而维持肌细胞正常能量需求来实现。.

Abstract The sympathetic nervous system inhibits gut motility, secretion, and blood flow in the gut microvasculature and can modulate gastrointestinal inflammation. Sympathetic neurons signal via catecholamines, neuropeptides, and gas mediators. In the current review, we summarize the current understanding of the mature sympathetic innervation of the gastrointestinal tract with a focus mainly on the prevertebral sympathetic ganglia as the main output to the gut. We also highlight recent work regarding the developmental processes of sympathetic innervation. The anatomy, neurochemistry, and connections of the sympathetic prevertebral ganglia with different parts of the gut are considered in adult organisms during prenatal and postnatal development and aging. The processes and mechanisms that control the development of sympathetic neurons, including their migratory pathways, neuronal differentiation, and aging, are reviewed.

ABSTRACT The objective of this article is to evaluate whether the tumoricidal activity of mouse IFN R −/− nature killer (NK) cells is induced by Newcastle disease virus hemagglutinin‐neuraminidase (NDV‐HN) stimulation, and to investigate what is the mechanism of the HN‐stimulated NK cells to kill mouse hepatoma cell line in vitro . The mouse IFN R −/− NK cells were stimulated for 16 hr with 500 ng/mL NDV‐HN in 1640 medium. Quantify the cytotoxic activities of NK cells against mouse hepatoma cells (Hepa1‐6) by flow cytometry. Granzymes B (GrB) and Fas/FasL concentrations in the supernatants of IFN R −/− NK cells medium were determined by specific ELISA assay. The expression of cell surface GrB and Fas was determined by Western blot. NDV‐HN stimulation enhanced tumoricidal activity of IFN R −/− NK cells toward Hepa1‐6 in vitro . Treating with anti‐HN neutralizing mAb induced significant decline in the cytotoxicity of IFN R −/− NK cells toward Hepa1‐6 cell line ( P &lt; 0.05). After treating with anti‐HN protein (1 μL/mL), Syk‐specific inhibitor Herbimycin A(250 ng/mL) and NF‐κB inhibitor PDTC (500 ng/mL) downregulated the tumoricidal activity of HN‐stimulated IFN R −/− NK cells ( P &lt; 0.05). Moreover, significant suppressions in the production of GrB and Fas/FasL were observed in HN‐stimulated IFN R −/− NK cells ( P &lt; 0.05). Thus, we concluded that killer activation receptors pathway is involved in the IFN‐γ‐independent GrB and Fas/FasL expression of NDV‐HN‐stimulated IFN R −/− NK cells, and these are activated by Syk and NF‐κB.

Abstract The fine structures, enzyme histochemical, and immunohistochemical characterization of liver in zebrafish were investigated using light microscopy and electron microscopy. The results showed that liver was separated into three lobes and each lobe had a central vessel comparable to the mammalian central vein. However typical hepatic lobules, portal areas, and hepatic arteries were not observed. A portal vein entered the liver and its tributaries were connected directly to the sinusoids, which then converged to the central vessel. Three central vessels in lobes finally carried the blood out of liver. The polygonal and bilayered hepatocytes were arranged as twisting, branching, and anastomosing cords. Ultrastructurally, they showed apparent morphological features of protein synthesis and secretion. Bile entered the biliary tree through the intracellular canaliculus, the ramifications of intercellular canaliculi that originated near the hepatic nucleus and then extended to the hepatocyte surface where two adjacent hepatocyte membranes formed intercellular canaliculi, and then ran sequentially through bile preductules, bile ductules, and bile ducts to be secreted out of the liver. Bile preductular epithelial cells (BPs) were cells located between bilayered hepatocytes in one hepatic cord. Occasionally, some tight junctions were detected forming the link between BPs and hepatocytes, which led us to assume that BPs might have a close relationship with hepatocytes during evolution. The present results indicate that zebrafish liver has its own specific fine structure. Anat Rec, 2012. © 2012 Wiley Periodicals, Inc.

Fine Structure, Enzyme Histochemistry, and Immunohistochemistry of Liver in Zebrafish

Pseudosuchia, one of the two main clades of Archosauria, is today only represented by some 20 extant species, the crocodilians, representing only a fraction of its extinct diversity. Extant crocodilians are ectotherms but present morphological and anatomical features usually associated with endothermy. In 2004, it was proposed that pseudosuchians were ancestrally endothermic and the features observed in extant crocodilians are the remains of this lost legacy. This contribution has two parts: the first part covers 20 years of studies on this subject, first exploring the evidence for a loss of endothermy in extant crocodilians, before covering the variety of proxies used to infer the thermophymetabolic regime of extinct pseudosuchians. In the second part, the quantitative results of these previous studies are integrated into a comprehensive ancestral state reconstruction to discuss a potential scenario for the evolution of thermometabolism. Pseudosuchian endothermy would then have been lost close to the node Crocodylomorpha. The end-Triassic mass extinction is proposed to have played the role of a filter, leading to the extinction of endothermic pseudosuchians and the survival of ectothermic ones. This difference in survival in Pseudosuchia is compared to those of dinosaurs, and difference in their metabolism is also considered. Pseudosuchian endothermy might have been of a different level than the dinosaurian one and more studies are expected to clarify this question.

Xenodens calminechari is a mosasaurid taxon named by Longrich et al. (2021) based on the holotype MHNM.KH.331, a left maxilla with several teeth. This holotype was obtained nonscientifically (without technical supervision) from an area in Morocco that yields many manipulated or forged specimens. Examination of Longrich et al. (2021) reveals four tooth crowns occupy what appear to be two alveoli in MHNM.KH.331, and there is potential adhesive connecting the tooth crowns to the maxilla on their lateral sides. We argue that the articulated tooth crowns of this taxon were artificially placed in the maxilla, rendering at least two apomorphies of this taxon the product of forgery. Longrich et al. (2021)'s claims of fused tooth 'roots' in MNHM.KH.331 are instead calcified periodontal ligament and alveolar bone that have ankylosed, resembling the typical mosasaurid condition. Differing tooth crown morphology does not preclude the referral of the teeth of this specimen to a younger ontogenetic stage of another mosasaur (possibly Carinodens) because many extant lizard species show drastic ontogenetic changes in the dentition. We argue that Xenodens calminechari represents a nomen dubium. This specimen constitutes a confluence of two persistent problems in vertebrate paleontology: material sourced from commercial excavations that has not been adequately tested for forgery, and taxa named from tooth-based holotypes that ignore the potential for intraspecific dental variation and interspecific convergence in dental characters, as are common in squamates. We suggest that Longrich et al. CT scan MHNM.KH.331, and we supply CT examples for identifying artificially added tooth crowns to Moroccan mosasaur jaws. Finally, we provide recommendations for the designation of mosasaurid holotypes.

In the context of an increasing interest for Pseudosuchia, we have compiled a Special Issue, comprising 14 collaborative studies that deepen our understanding of pseudosuchian evolution. These contributions range from the description of a new taxon to exhaustive reviews of thermometabolism, morphological adaptation, systematics, and detailed investigations into ontogeny, paleoneurology, paleohistology, and paleobiology. Through these papers, we explore the evolutionary history of pseudosuchian archosaurs, spotlighting their rise and diversification following the end-Permian mass extinction.

伪鳄类：生存与多样化的主宰

Abstract Crocodylians evolved a unique gular valve that is capable of creating a water‐tight seal between the oral and pharyngeal cavities, allowing the animal to safely submerge with an open mouth. The gular valve has traditionally been described as consisting of two separate parts: an active mobile ventral portion (consisting of the tongue and portions of the hyolingual apparatus) and a dorsal portion, which is a static fold on the hard palate (often termed the palatal velum). The results of the present study argue that the two portions of the gular valve are functionally integrated, not separate, and that the dorsal portion (herein the dorsal gular fold) is a dynamic element the shape and tension of which are influenced by active and passive forces. Using gross dissection, histology, and DiceCT, the present study documents a previously underscribed component of the gular valve, the velar chord, which links the hyolingual apparatus to the dorsal gular fold, functionally integrating the two halves of the gular valve. Through endoscopic videography and a variety of manipulations on living crocodylians, this study demonstrates that changes in the tension on the velar chord directly alter the shape and tension of the dorsal gular fold. The shape changes observed in the dorsal gular fold could be accommodated by a shallow depression in the ventral surface of the palatine bones, herein termed the velar fossa. The velar fossa is a prominent feature of Alligator mississippiensis and was observed in other crocodilians; however, a survey of living and fossil crocodylians demonstrated that the velar fossa is not a universal feature in this clade. Understanding the functional linkage between the dorsal and ventral portions of the gular valve has implications beyond the dive reflex of crocodylians, since active manipulation of the dorsal gular fold likely plays a role in a variety of behavioral and physiological processes such as deglutition and vocalization.

Abstract Understanding patterns of cortico‐cortical connections in both frequently and infrequently studied species advances our knowledge of cortical organization and evolution. The agouti ( Dasyprocta aguti , a medium‐size South American rodent) offers a unique opportunity, because of its large lissencephalic brain and its natural behaviors, such as gnawing and hiding seeds, that require bimanual interaction while sitting on its hindlimbs and aligning its head to receive images of the horizon on the retinal visual streak. There have been no previous studies of the intrinsic and extrinsic ipsilateral projections of the agouti's primary somatosensory cortical area (S1). In the present study, we utilized biotinylated dextran (BDA) anatomical tract‐tracer injections combined with microelectrode electrophysiological mapping, correlated with analysis of cytochrome oxidase (CO) histochemical staining, to investigate the ipsilateral corticocortical connectivity of the agouti's S1. By injecting BDA into electrophysiologically identified regions within the S1, we revealed ipsilateral intrinsic connections, as well as connections with cortical areas rostral and caudal to S1, and homotopic labeling in the second somatosensory cortical area (S2). In addition, we identified a focal cluster of labeled axons and axonal terminals adjacent to the rhinal fissure, tentatively named the parietal rhinal area (PR). The analysis of CO reactivity allowed delineation of the boundaries and subdivisions of S1, as well as the locations and limits of primary auditory and visual areas. These findings provide support for the notion of a similar pattern of somatosensory cortical organization and connectivity across mammalian species.
