December 2024

Stazione Sperimentale Per L'industria Delle Pelli E Delle Materie Concianti S.R.L., 80143, Napoli, Italy.

Leather manufacturing is the process of converting raw animal hides or skins into finished leather. The complex industrial procedures result in a tanning effluent composed of chemical compounds with potentially hazardous impacts on humans and ecosystems. Among the traditional and efficient wastewater treatments, adsorption is an effective and well-known approach, able to manage a wide range of contaminants from wastewater.

Department of Agricultural Science, University of Naples, via Università, 100, Portici 80055, Italy; Centro Interdipartimentale di Ricerca per la Risonanza Magnetica Nucleare per l'Ambiente, l'Agroalimentare, ed i Nuovi Materiali (CERMANU), Università di Napoli Federico II, Via Università 100, 80055 Portici, Italy.

Coffee husks have been valorised by isolating humic materials before (HLS-Raw) or after (HS-Comp) composting them. Such substrates were reacted with chitosan at different ratios to synthesize novel nanoparticles (NP) with radical scavenging properties. Size and antioxidant activity of nanomaterials increased at higher HS/chitosan ratio, while zeta potential decreased.

Diverse tissues in vivo present varying degrees of confinement, constriction, and compression to migrating cells in both homeostasis and disease. The nucleus in particular is subjected to external forces by the physical environment during confined migration. While many systems have been developed to induce nuclear deformation and analyze resultant functional changes, much remains unclear about dynamic volume regulation in confinement due to limitations in time resolution and difficulty imaging in PDMS-based microfluidic chips.

X-ray radiation treatments are largely adopted in radiotherapy, and Fourier-transform infrared microspectroscopy (μ-FTIR) has already been demonstrated to be a useful instrument for monitoring radiotherapy effects. Previous works in this field have focused on studying the changes occurring in cells when they are fixed immediately after the irradiation or 24 and 48 h later. In the present paper, changes occurring in SH-SY5Y neuroblastoma cells in the first hours after the irradiation are examined to obtain information on the processes taking place in this not-yet-investigated time window by using μ-FTIR.

Carbapenem-resistant Enterobacterales (CREs) are globally considered to be a major threat to public health. National and international guidelines emphasize the importance of routine active surveillance policies to prevent their transmission. Consequently, screening for the evaluation of the status of colonization by CREs in hospitalized patients in Italy is considered essential to contain and control the spread of these microorganisms and their evolution towards infection.

Water confined in nanoscale cavities plays a crucial role in everyday phenomena in geology and biology, as well as technological applications at the water-energy nexus. However, even understanding the basic properties of nano-confined water is extremely challenging for theory, simulations, and experiments. In particular, determining the melting temperature of quasi-one-dimensional ice polymorphs confined in carbon nanotubes has proven to be an exceptionally difficult task, with previous experimental and classical simulation approaches reporting values ranging from ∼180 K up to ∼450 K at ambient pressure.

Endocrinology Unit, Department of Clinical and Molecular Medicine, Sant'Andrea Hospital, European Neuroendocrine Tumor Society (ENETS) Center of Excellence, Sapienza University of Rome, Rome, Italy.

Neuroendocrine neoplasms (NENs) originating in the gastroenteropancreatic (GEP) tract are rare tumors often associated with significant metabolic disturbances and nutritional challenges. This review explores the intricate relationship between nutritional status and the development, progression, and prognosis of GEP-NENs. Through an extensive literature search encompassing studies up to April 2024, we examined various factors, including obesity, malnutrition, metabolic syndrome and type 2 diabetes mellitus, and their roles in the development and progression of GEP-NENs.

Optical tweezers exploit light-matter interactions to trap particles ranging from single atoms to micrometer-sized eukaryotic cells. For this reason, optical tweezers are a ubiquitous tool in physics, biology, and nanotechnology. Recently, the use of deep learning has started to enhance optical tweezers by improving their design, calibration, and real-time control as well as the tracking and analysis of the trapped objects, often outperforming classical methods thanks to the higher computational speed and versatility of deep learning.

The Ross Ice Shelf floats above the southern sector of the Ross Sea and creates a cavity where critical ocean-ice interactions take place. Crucial processes occurring in this cavity include the formation of Ice Shelf Water, the coldest ocean water, and the intrusion of Antarctic Surface Water, the main driver of frontal and basal melting. During the winter, a polynya forms along the Ross Ice Shelf edge, producing a precursor to Antarctic Bottom Water known as High Salinity Shelf Water.

Effects of Nanofat and PRP on Type I Collagen Production in Striae Distensae: Preliminary Findings from a Prospective, Randomized Single-Blind Study.

Aesthetic Plast Surg

December 2024

Department of Plastic, Reconstructive and Maxillo facial Surgery, Henri Mondor Hospital, University Paris XII, 51 Avenue du Maréchal de Lattre de Tassigny, 94000, Créteil, France.

Introduction: Striae distensae (SD) appear clinically as parallel striae, lying perpendicular to the tension lines of the skin. SD evolve into two clinical phases, an initial inflammatory phase in which they are called "striae rubrae" (SR) and a chronic phase in which they are called striae albae (SA). This study investigates the synergistic effect of nanofat and platelet-rich plasma (PRP) injections on collagen production in fibroblasts derived from SA (SAF).
