How interpersonal distance varies throughout the lifespan.

Interpersonal Distance (IPD) is defined as the physical distance that individuals maintain between themselves and others during social interactions. While literature has extensively focused on this everyday social behavior, how IPD changes throughout the lifespan remains an open question. In this study, 864 participants, aged 3-89 years, performed the Stop Distance Paradigm in their real-life environments, and we measured the distance they kept from both familiar and unfamiliar others during social interactions.

Ultra-fast and automated immunohistofluorescent multistaining using a microfluidic tissue processor.

Multistaining of a tissue section targeting multiple markers allows to reveal complex interplays in a tumor environment. However, the resource-intensive and impractically long nature of iterative multiplexed immunostainings prohibits its practical implementation in daily routine, even when using work-flow automation systems. Here, we report a fully automated and ultra-fast multistaining using a microfluidic tissue processor (MTP) in as short as 20 minutes per marker, by immunofluorescent staining employing commercially available tyramide signal amplification polymer precipitation by horse-radish peroxidase (HRP) activation.

A microfluidic platform towards automated multiplexed in situ sequencing.

Advancements in multiplexed in situ RNA profiling techniques have given unprecedented insight into spatial organization of tissues by enabling single-molecule quantification and sub-micron localization of dozens to thousands of RNA species simultaneously in cells and entire tissue sections. However, the lack of automation of the associated complex experimental procedures represents a potential hurdle towards their routine use in laboratories. Here, we demonstrate an approach towards automated generation and sequencing of barcoded mRNA amplicons in situ, directly in fixed cells.

Label-free detection of tobramycin in serum by transmission-localized surface plasmon resonance.

In order to improve the efficacy and safety of treatments, drug dosage needs to be adjusted to the actual needs of each patient in a truly personalized medicine approach. Key for widespread dosage adjustment is the availability of point-of-care devices able to measure plasma drug concentration in a simple, automated, and cost-effective fashion. In the present work, we introduce and test a portable, palm-sized transmission-localized surface plasmon resonance (T-LSPR) setup, comprised of off-the-shelf components and coupled with DNA-based aptamers specific to the antibiotic tobramycin (467 Da).

[Italian multicenter study for the verification of the efficacy and tolerability of short-term substitution hormone therapy using conjugated estrogens and progestagens administered orally in the postmenopausal a period].

Three hundred and sixty-three postmenopausal women received 6 months of cyclic hormone replacement therapy with conjugated estrogens in differing doses (0.625 mg and 1.25 mg) associated in a sequential pattern lasting 12 days with progestagens (medroxyprogesterone acetate or medrogestone) in 16 italian health centres.
