Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential
FEBS Letters, EarlyView.Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Method for characterization of Si waveguide propagation loss
Optics Express, 2013 A new method for measuring waveguide propagation loss in silicon nanowires is presented. This method, based on the interplay between traveling ring modes and standing wave modes due to back-scattering from edge roughness, is accurate and can be used for on wafer measurement of test structures. Examples of loss measurements and fitting are reported.

An epithelial GPR35 isoform supports tumor‐associated transcriptional and metabolic phenotypes
FEBS Letters, EarlyView.GPR35 generates two functionally distinct isoforms with previously unresolved roles. GPR35‐short mediates immune‐cell chemotaxis, while GPR35‐long is enriched in colorectal cancer epithelium, where it supports increased metabolism, proliferation, and tumor‐associated transcriptional programs.

Propagation Losses of Slotted Photonic Crystal Waveguides
IEEE Photonics Journal, 2012 We have fabricated and characterized a set of slotted photonic crystal (SPhC) waveguides in silicon-on-insulator (SOI) with a length of up to 300 $\mu\hbox{m}$ and slot widths ranging between 115 and 145 nm. We observe an upper limit for the loss of 11 dB/cm.

Liver organoids: modelling complexity in homeostasis and disease
FEBS Letters, EarlyView.Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

Methods and algorithms for electromagnetic waves propagation in indoor environments [PDF]
, 2008 In this thesis has been discussed a model, defined to describe electromagnetic propagation phenomena, at high frequencies, in an indoor environment. The aim was to define a method useful to achieve sufficiently reliable and quick predictions of the power
