In preclinical experiments, cyclic fasting-mimicking diets (FMDs) showed broad anticancer effects in combination with chemotherapy. Among different tumor types, triple-negative breast cancer (TNBC) is exquisitely sensitive to FMD. However, the antitumor activity and efficacy of cyclic FMD in TNBC patients remain unclear.

Colorectal cancer (CRC) remains challenging to diagnose, necessitating the identification of a noninvasive biomarker that can differentiate it from other conditions such as inflammatory bowel diseases (IBD) and diverticular disease (DD). Raman spectroscopy (RS) stands out as a promising technique for monitoring blood biochemical profiles, with the potential to identify distinct signatures identifying CRC subjects. We performed RS analysis on dried plasma from 120 subjects: 32 CRC patients, 37 IBD patients, 20 DD patients, and 31 healthy controls.

The widespread use of synthetic composite materials has raised environmental concerns due to their non-biodegradability and energy-intensive production. This paper explores the potential of natural composites, specifically flax-polypropylene, as a sustainable alternative to traditional composites for semi-structural applications. In fact, the mechanical properties of flax-polypropylene composites are similar to synthetic ones (such as those made with E-glass fibers).

Article Synopsis
  • Colorectal cancer (CRC) is linked to factors like obesity and inflammation, which may disrupt immune response by accumulating foam cells (FC) in tumors, potentially impacting cancer progression.*
  • The study involved analyzing tumor samples from CRC patients to investigate the relationship between FC and immune cell dynamics, highlighting the presence of reduced CD8 T cells and increased regulatory T cells in tumors with high FC accumulation.*
  • Results indicated that higher levels of FC are associated with worse outcomes, including lower disease-free survival rates in CRC, and in vitro experiments showed that FC suppress CD8 T cell activity through mechanisms involving TGF-β.*

Purpose: Anastomotic leak (AL) remains the most important complication after left-sided colic anastomoses and technical complications during anastomotic construction are responsible of higher leakage incidence. Powered circular stapler (PCS) in colorectal surgery has been introduced in order to reduce technical errors and post-operative complications due to the manual circular stapler (MCS).

Methods: A systematic review and meta-analysis were performed.

Aim: Improvement in oncological survival for rectal cancer increases attention to anorectal dysfunction. Diagnostic questionnaires can evaluate quality of life but are subjective and dependent on patients' compliance. Anorectal manometry can objectively assess the continence mechanism and identify functional sphincter weakness and rectal compliance.

Locally recurrent rectal cancer is resected with clear margins in only 50% of cases, and these patients achieve a three-year survival rate of 50%. Outcomes and therapeutic strategies for nonresectable locally recurrent rectal cancer have been much less explored. The aim of the study was to assess the three-year progression-free survival and the three-year overall survival in locally recurrent rectal cancer patients treated by chemotherapy/chemoradiation only vs.

Locally recurrent rectal cancer (LRRC) involving the lateral pelvic sidewall requires a complex approach to maximize the likelihood of R0 resection, which is the only predictor of survival. The purpose of this report is to describe a novel technique to resect a localized lateral pelvic sidewall LRRC. A 63-year-old male patient was referred for a 15-mm LRRC near the right internal iliac vessels.

Introduction: Fast and accurate diagnosis of acute stroke is crucial to timely initiate reperfusion therapies. Conventional high-field (HF) MRI yields the highest accuracy in discriminating early ischaemia from haemorrhages and mimics. Rapid access to HF-MRI is often limited by contraindications or unavailability.

Metal lattice structures manufactured utilising additive techniques are attracting increasing attention thanks to the high structural efficiency they can offer. Although many studies exist on the characterisation of massive parts in Ti6Al4V processed by Electron Beam Melting (EBM), several investigations are necessary to characterise the Ti6Al4V lattice structures made by the EBM process. The objective of this paper is to develop a measurement method to assess the dimensional accuracy of Ti6Al4V octet truss lattice structures manufactured by EBM technology.

In this work, a dual objective is carried out on composite materials in flax fiber and bio-based epoxy resin: to determine the process parameters and to develop a numerical model for highlighting the potential of and the limits in the production of "green" laminates through a RIFT process (Resin Infusion under Flexible Tool). For these reasons, compressibility tests were performed in order to evaluate the behavior of commercial flax woven under the vacuum bag. Subsequently, permeability tests were performed in order to evaluate the permeability curves necessary for the numerical study of the infusion process.

Antimicrobial resistance (AMR) poses a serious threat to our society from both the medical and economic point of view, while the antibiotic discovery pipeline has been dwindling over the last decades. Targeting non-essential bacterial pathways, such as those leading to antibiotic persistence, a bacterial bet-hedging strategy, will lead to new molecular entities displaying low selective pressure, thereby reducing the insurgence of AMR. Here, we describe a way to target (p)ppGpp (guanosine tetra- or penta-phosphate) signaling, a non-essential pathway involved in the formation of persisters, with a structure-based approach.

Inhibitors of apoptosis proteins (IAPs) are validated onco-targets, as their overexpression correlates with cancer onset, progression, diffusion and chemoresistance. IAPs regulate cell death survival pathways, inflammation, and immunity. Targeting IAPs, by impairing their protein-protein interaction surfaces, can affect events occurring at different stages of cancer development.
