    Abstract Depuis une trentaine dannées, létude des ordres militaires au Moyen Âge a enregistré un profond renouvellement auquel Alain Demurger a particulièrement œuvré. Derrière lhistoire politique, par-delà les rouages institutionnels, la recherche sest toujours plus attachée à considérer les hommes. Pourtant, la question des élites, sagissant des frères, na jamais été analysée sinon de façon ponctuelle. En considérant à la fois les élites sociales, nobles ou citadines, les élites de pouvoir et de gouvernement et les propres élites des ordres militaires, ce livre napporte pas seulement un nouvel éclairage sur lhistoire des frères. Il contribue plus largement à la connaissance des sociétés médiévales, du xiie au xve siècle, depuis la péninsule Ibérique jusquà la Baltique et à lOrient méditerranéen

    Abstract The broadband absorption coefficient spectrum of the rabbit lung presents some particular characteristics that allow the identification of the chromophores in this tissue. By performing a weighted combination of the absorption spectra of water, hemoglobin, DNA, proteins and the pigments melanin and lipofuscin, it was possible to obtain a good match to the experimental absorption spectrum of the lung. Such reconstruction provided reasonable information about the contents of the tissue components in the lung tissue, and allowed to identify a similar accumulation of melanin and lipofuscin.

    Abstract This paper addresses some elements regarding the zero hour employment contract (ZHC), introduced by Law no. 13.467 of 2017 in Brazil. To this end, it performs a characterization of these employees, and compares them with other workers in the formal and informal sector. It then presents the recent evolution ZHC workers admissions in the Brazilian labor market. Although there is little evidence regarding the hours and salary received by these workers, it is noted that ZHC workers are more concentrated in specific activities than other workers. Furthermore, they are no different, in terms of average qualification, from other formal workers. Finally these results are stable in terms of disaggregation into knowledge, skills and attitudes. These arguments, together with the existing labor protection in the country, favor the understanding that there is decent of work due the recent legal framework in the country.

    Abstract Keratoconus (KC) is a bilateral ectatic corneal disease which results in changes in the corneal architecture and can lead to severe visual impairment. Treatment options depend on the stage of the disease, and they aim either at improving vision or arrest progression. The Bowman layer transplantation (BLT) is a recent surgical option in patients with KC and may postpone corneal transplantation in some patients. We present a case of a 22-year-old patient with a 10-year follow-up history of progressing KC. A first attempt for an intracorneal ring segment (ICRS) implantation when he was 13 years old was unsuccessful due to a superficially implanted segment. At that time, collagen cross-linking was unavailable, and his young age raised concerns about performing a penetrating keratoplasty/lamellar keratoplasty. A BLT was performed with further ICRS implantation with relative disease stability and visual improvement. ICRS implantation in KC patients with BLT has not previously been described in literature and can be an option in selected patients.

    Abstract Background: Bile acids (BAs) are steroid molecules synthesized exclusively in the liver, being end products of cholesterol catabolism. BAs are known to be involved in several metabolic alterations, including metabolic syndrome and type 2 diabetes mellitus (DM2). DM2 is a chronic degenerative disease characterized by insulin resistance, insulin deficiency due to insufficient production of pancreatic ß-cells, and elevated serum glucose levels leading to multiple complications.
    Objective: The objective of this study is to investigate the role of BAs in the pathophysiology of DM2, highlighting the possibilities in the development of therapeutic procedures targeting BAs as an optional pathway in the treatment of DM2.
    Methods: The research was carried out through narrative review and publications on the relationship between BAs and DM2. The databases used for the search include PubMed, Scopus, and Web of Science. The keywords used for the search include bile acids, type 2 diabetes mellitus, metabolic syndrome, and metabolic disorders.
    Results: The studies have reported the involvement of BAs in the pathophysiology of DM2. BAs act as a ligand for the nuclear farnesoid X receptor, regulating glucose metabolism, lipid metabolism, and cellular energy production. Additionally, BAs modulate the production, elimination, and mobilization of BAs through the farnesoid X receptor. BAs also act as a signaling pathway through Takeda G protein-coupled receptor 5, further contributing to metabolic regulation. These findings suggest that targeting BAs may offer a novel therapeutic approach in the treatment of DM2.
    Conclusion: This study highlights the important role of BAs in DM2, specifically through their interactions with key metabolic pathways. Targeting BAs may represent an innovative and effective approach to the treatment of DM2.

    Abstract The increase of tissue transparency through sequential optical immersion clearing treatments and treatment reversibility have high interest for clinical applications. To evaluate the clearing reversibility in a broad spectral range and the magnitude of the transparency created by a second treatment, the present study consisted on measuring the spectral collimated transmittance of lung tissues during a sequence of two treatments with electronic cigarette (e-cig) fluid, which was intercalated with an immersion in saline. The saline immersion clearly reverted the clearing effect in the lung tissue in the spectral range between 220 and 1000 nm. By a later application of a second treatment with the e-cig fluid, the magnitude of the optical clearing effect was observed to be about the double as the one observed in the first treatment, showing that the molecules of the optical clearing agent might have converted some bound water into mobile water during the first treatment.
