Abstract	Quantifying axonal branching is crucial for understanding neural circuit function, developmental and regeneration processes and disease mechanisms. Factors that regulate patterns of axonal arborization and tune neuronal circuits are investigated for their implication in various disorders in brain connectivity. The lack of a reliable and user-friendly method makes the quantitative analysis of axon morphology difficult. Specifically, methods to visualize and quantify the complex axon arborization are challenging to implement and apply practically. Our study was aimed at developing a robust but simple method of quantification that used ImageJ 2D analysis and compared it with Imaris visualization and analysis of 3D images. We used zebrafish fluorescent transgenic lines to perform in vivo imaging of developing motor neuron axons that adequately reflected the complexity of axonal networks. Our new method, developed on ImageJ, is easy and fast, giving access to new information such as collateral distribution along the axonal shaft. This study describes step-by-step procedures that can be easily applied to a variety of organisms and in vitro systems. Our study provides a basis for further exploration of neural circuits to gain new insights into neuronal disorders and potential therapeutic interventions.

Article: Phylogenetic and morphologic survey of orbicules in angiosperms

Abstract	Orbicules are granules of sporopollenin or polymorphic sporopollenin‐elements produced by the tapetum, associated with pollen grains and tapetum cells. In angiosperms, they are common in the ANA grade and monocots, but are absent in late‐branching clades such as the majority of Asteraceae and the majority of Lamiaceae, revealing an evolutionary trend from presence to absence along the phylogenetic tree. However, for several orders of angiosperms, no data on orbicules is available. We investigated orbicules in 34 species from 29 different genera and 14 orders, for which limited or no data was available (Acorales, Arecales, Buxales, Celastrales, Crossosomatales, Dilleniales, Escalloniales, Fagales, Garryales, Gunnerales, Paracryphiales, Santalales, Trochodendrales, Zygophyllales). We photographed pollen sacs and pollen grains with a SEM, then described selected orbicule traits and measured their size. We then calculated: (1) the phylogenetic signals for (a) orbicule size in a selected group of species and (b) presence/absence of orbicules in all angiosperm groups until now recorded in the literature; (2) the ancestral state of orbicule size; (3) origin, loss and transition rate for presence/absence of orbicules in angiosperms. Orbicule traits are supported both by a strong phylogenetic signal and by a significant evolutionary trait value. The evolutionary rate for the presence of orbicules confirms that it is a plesiomorphic trait showing adaptive radiation with a significant increase in origins and diversification, while the phylogenetic signal for size of the orbicules indicates evolutionary convergence. Furthermore, we detected an evolutionary trend towards a reduction in the size of orbicules, that might have led to their absence in most late‐branching clades.

Abstract	Objective: To investigate the relationship between perception of craniofacial deformity, geometric head features, and 3D head shape analyzed by statistical shape modeling (SSM). Patients: A total of 18 unoperated patients with scaphocephaly (age = 5.2 ± 1.1m)-6 were followed-up after spring-assisted cranioplasty (SAC) (age = 9.6 ± 1.5m)-and 6 controls (age = 6.7 ± 2.5m). Main outcome measures: 3D head shapes were retrieved from 3D scans or computed tomography (CTs). Various geometrical features were measured: anterior and posterior prominence, take-off angle, average anterior and posterior lateral and horizontal curvatures, cranial index (CI) (cranial width over length), and turricephaly index (TI) (cranial height over length). SSM and principal component analysis (PCA) described shape variability. All models were 3D printed; the perception of deformity was blindly scored by 9 surgeons and 1 radiologist in terms of frontal bossing (FB), occipital bulleting (OB), biparietal narrowing (BN), low posterior vertex (LPV), and overall head shape (OHS). Results: A moderate correlation was found between FB and anterior prominence (r = 0.56, Conclusions: Esthetic cranial appearance in craniofacial patients is correlated to specific geometric parameters and could be estimated using automated methods such as SSM.

Abstract	Three-dimensional virtual simulation of orthognathic surgery is now a well-established method in maxillo-facial surgery. The commercial software packages are still burdened by a consistent imprecision on soft tissue predictions. In this study, the authors produced an anatomically detailed patient specific numerical model for simulation of soft tissue changes in orthognathic surgery. Eight patients were prospectively enrolled. Each patient underwent CBCT and planar x-rays prior to surgery and in addition received an MRI scan. Postoperative soft-tissue change was simulated using Finite Element Modeling (FEM) relying on a patient-specific 3D models generated combining data from preoperative CBCT (hard tissue) scans and MRI scans (muscles and skin). An initial simulation was performed assuming that all the muscles and the other soft tissue had the same material properties (Homogeneous Model). This model was compared with the postoperative CBCT 3D simulation for validation purpose. Design of experiments (DoE) was used to assess the effect of the presence of the muscles considered and of their variation in stiffness. The effect of single muscles was evaluated in specific areas of the midface. The quantitative distance error between the homogeneous model and actual patient surfaces for the midface area was 0.55 mm, standard deviation 2.9 mm. In our experience, including muscles in the numerical simulation of orthognathic surgery, brought an improvement in the quality of the simulation obtained.

Abstract	This paper offers a practical overview of the contemporary management of patients with peripheral arterial disease presenting intermittent claudication (IC), including clinical and instrumental diagnosis, risk factors modification, medical management, and evidence-based revascularization indications and techniques. Decision making represents a crucial element in the management of the patient with IC; for this, we think a review of this type could be very useful, especially for non-vascular specialists.

Title translation	The role of extracellular matrix in the regeneration of motor nerves.
Abstract	The motor neurons (MN) form the ultimate route to convey the commands from the central nervous system to muscles. During development, MN extend axons that follow stereotyped trajectories to their muscle targets, guided by various attractive and repulsive molecular cues. Extracellular matrix (ECM) is a major source of guidance cues, but its role in axonal development and regeneration remains poorly documented. Regenerating axons are able to return to their synaptic target following their original trajectory. The same guidance cues could be thus involved in motor nerve regeneration. Zebrafish has become a popular model system in understanding the development of the peripheral nervous system. Thanks to the generation of fluorescent transgenic lines and the optical transparency of embryos and larvae, it allows direct visualization of axonogenesis. Additionally, and contrary to humans, its remarkable capacity to regenerate makes it well suited for the study of nerve regeneration. A laser method to ablate nerves in living zebrafish larvae has been developed in our laboratory that, combined with the use of the fluorescent mnx1:gfp zebrafish transgenic line, allows the follow up of the dynamics of the nerve regeneration process. To study the role of ECM proteins present in the axonal path, mutant lines for different ECM proteins (already available in our laboratory or generated in mnx1:gfp fish using CRISPR-Cas9 method) will be used to analyze their role during the regeneration process. These mutant lines for ECM will be crossed with existing fluorescent transgenic lines to visualize different cell types involved in the nerve regeneration, such as macrophages (mfap4:mcherry), neutrophils (mpx:gfp) or even Schwann cells (sox10:mrfp). Overall, this study will depict the role of ECM in nerve regeneration and will provide essential knowledge for the development of new biomaterials to promote the regeneration of injured motor nerves.

Abstract	The authors present the life and art of Giuseppe Dagnini, a renowned Italian physician who was born in Bologna in 1866. He was the chief of the Maggiore Hospital in Bologna and authored valuable scientific works on the trigemino-cardiac reflex which is still applied in modern clinical practice. Dr. Dagnini firstly described the reflex in 1908 postulating that stimulation of one of the 3 branches of the trigeminal nerve triggers the afferent pathway in lowering heart rate. The authors also provide a modern outlook on the clinical implications of the TCR in neurosurgery, neuroanesthesia, and other medical specialties.

Abstract	In this paper, disturbance reconstruction and robust trajectory tracking control of biped robots with hybrid dynamics in the port-Hamiltonian form is investigated. A new type of Hamiltonian function is introduced, which ensures the finite-time stability of the closed-loop system. The proposed control system consists of two loops: an inner and an outer loop. A fractional proportional-integral-derivative filter is used to achieve finite-time convergence for position tracking errors at the outer loop. A fractional-order sliding mode controller acts as a centralized controller at the inner-loop, ensuring the finite-time stability of the velocity tracking error. In this loop, the undesired effects of unknown external disturbance and parameter uncertainties are compensated using estimators. Two disturbance estimators are envisioned. The former is designed using fractional calculus. The latter is an adaptive estimator, and it is constructed using the general dynamic of biped robots. Stability analysis shows that the closed-loop system is finite-time stable in both contact-less and impact phases. Simulation studies on two types of biped robots (i.e., two-link walker and RABBIT biped robot) demonstrate the proposed controller's tracking performance and disturbance rejection capability.
