AJNR Am J Neuroradiol 2022 May 26. Epub 2022 May 26.

From the Divisions of Radiology (V.L., B.M.A.D., Y.M., T.d.P., M.B.)

Background And Purpose: Controversy exists as to whether ADC histograms are capable to distinguish human papillomavirus-positive (HPV+) from human papillomavirus-negative (HPV-) oropharyngeal squamous cell carcinoma. We investigated how the choice of b-values influences the capability of ADC histograms to distinguish between the two tumor types.

Materials And Methods: Thirty-four consecutive patients with histologically proved primary oropharyngeal squamous cell carcinoma (11 HPV+ and 23 HPV-) underwent 3T MR imaging with a single-shot EPI DWI sequence with 6 b-values (0, 50, 100, 500, 750, 1000 s/mm). Read More

Immune determinants of endometrial receptivity: a biological perspective.

Fertil Steril 2022 Jun;117(6):1107-1120

Robinson Research Institute and Adelaide Medical School, The University of Adelaide, Adelaide, South Australia, Australia.

Immune cells are essential for endometrial receptivity to embryo implantation and early placental development. They exert tissue-remodeling and immune regulatory roles-acting to promote epithelial attachment competence, regulate the differentiation of decidual cells, remodel the uterine vasculature, control and resolve inflammatory activation, and suppress destructive immunity to paternally inherited alloantigens. From a biological perspective, the endometrial immune response exerts a form of "quality control"-it promotes implantation success when conditions are favorable but constrains receptivity when physiological circumstances are not ideal.

Center for Advanced Biomaterials for [email protected], Istituto Italiano di Tecnologia, Naples, Italy. Electronic address:

Here, we propose an immune-responsive human Microbiota-Intestine axis on-chip as a platform able to reproduce the architecture and vertical topography of the microbiota with a complex extracellular microenvironment consisting of a responsive extra cellular matrix (ECM) and a plethora of immune-modulatory mediators released from different cell populations such as epithelial, stromal, blood and microbial species in homeostatic and inflamed conditions. Firstly, we developed a three-dimensional human intestine model (3D-hI), represented by an instructive and histologically competent ECM and a well-differentiated epithelium with mucus-covered microvilli. Then, we replicated the microenvironmental anaerobic condition of human intestinal lumen by fabricating a custom-made microbiota chamber (M) on the apical side of the Microbiota-human Intestine on chip (MihI-oC), establishing the physiological oxygen gradient occurring along the thickness of human small intestine from the serosal to the luminal side.
