pCR and 2-Year Disease-Free Survival: A Combination of the Two Endpoints as a New Classification for Locally Advanced Rectal Cancer Patients-An Updated Pooled Analysis of Eleven International Randomized Trials.

LARC is managed by multimodal treatments whose intensity can be highly modulated. In this context, we need surrogate endpoints to help predict long-term outcomes and better personalize treatments. A previous study identified 2yDFS as a stronger predictor of OS than pCR in LARC patients undergoing neoadjuvant RT.

Delta Radiomic Analysis of Mesorectum to Predict Treatment Response and Prognosis in Locally Advanced Rectal Cancer.

Background: The aim of this study is to evaluate the delta radiomics approach based on mesorectal radiomic features to develop a model for predicting pathological complete response (pCR) and 2-year disease-free survival (2yDFS) in locally advanced rectal cancer (LARC) patients undergoing neoadjuvant chemoradiotherapy (nCRT).

Methods: Pre- and post-nCRT MRIs of LARC patients treated at a single institution from May 2008 to November 2016 were retrospectively collected. Radiomic features were extracted from the GTV and mesorectum.

Mirage of Luminal Modified Gravitational-Wave Propagation.

Using conformal invariance of gravitational waves, we show that for a luminal modified gravity theory, the gravitational-wave propagation and luminosity distance are the same as in general relativity. The relation between the gravitational-wave and electromagnetic-wave luminosity distance gets modified, however, for electromagnetism minimally coupled to the Jordan frame metric. Using effective field theory we show that the modified relation obtained for luminal theories is also valid for nonluminal theories with Jordan frame matter-gravity coupling.

Wing morphology covaries with migration distance in a highly aerial insectivorous songbird.

According to classical prediction of aerodynamic theory, birds and other powered fliers that migrate over long distances should have longer and more pointed wings than those that migrate less. However, the association between wing morphology and migratory behavior can be masked by contrasting selective pressures related to foraging behavior, habitat selection and predator avoidance, possibly at the cost of lower flight energetic efficiency. We studied the handwing morphology of Eurasian barn swallows from four populations representing a migration distance gradient.

The impact of labyrinthine magnetic resonance signal alterations on the treatment of sudden sensory-neural hearing loss.

Background: Sudden sensory-neural hearing loss SSNHL), with positive findings on magnetic resonance imaging (MRI), possibly related to labyrinthine hemorrhage, is a rare condition and difficult to be diagnosed.

Methods: A prospective study was held between January and June 2022.

Daily SARS-CoV-2 Nasal Antigen Tests Miss Infected and Presumably Infectious People Due to Viral Load Differences among Specimen Types.

In a recent household transmission study of SARS-CoV-2, we found extreme differences in SARS-CoV-2 viral loads among paired saliva, anterior nares swab (ANS), and oropharyngeal swab specimens collected from the same time point. We hypothesized these differences may hinder low-analytical-sensitivity assays (including antigen rapid diagnostic tests [Ag-RDTs]) by using a single specimen type (e.g.

Pediatric low-grade glioma and neurofibromatosis type 1: A single-institution experience.

Background: Neurofibromatosis type 1 (NF1)-related gliomas appear to have a clinical behavior different from that of sporadic cases. The purpose of the study was to investigate the role of different factors in influencing the tumor response rate of children receiving chemotherapy for their symptomatic glioma.

Methods: Between 1995 and 2015, 60 patients with low-grade glioma (42 sporadic cases and 18 cases with NF1) were treated.

The impact of adipose tissue distribution on endometrial cancer: a systematic review.

Introduction: Endometrial cancer (EC) is the most common gynecological cancer with a rising incidence, attributed to advanced life expectancy and obesity.

An aqueous olive leaf extract (OLE) ameliorates parameters of oxidative stress associated with lipid accumulation and induces lipophagy in human hepatic cells.

Fatty liver is a disease characterized by a buildup of lipids in the liver, often resulting from excessive consumption of high-fat-containing foods. Fatty liver can degenerate, over time, into more severe forms of liver diseases, especially when oxidative stress occurs. Olive leaf extract (OLE) is a reliable source of polyphenols with antioxidant and hypolipidemic properties that have been successfully used in medicine, cosmetics, and pharmaceutical products.

Levulinic Acid-Based "Green" Solvents for Lignocellulose Fractionation: On the Superior Extraction Yield and Selectivity toward Lignin.

The high potential use of lignin in novel biomaterials and chemicals represents an important opportunity for the valorization of the most abundant natural resource of aromatic molecules. From an environmental perspective, it is highly desirable replacing the hazardous methods currently used to extract lignin from lignocellulosic biomass and develop more sustainable and environmentally friendly approaches. Therefore, in this work, levulinic acid (a "green" solvent obtained from biomass) was successfully used, for the first time, to selectively extract high-quality lignin from pine wood sawdust residues at 200 °C for 6 h (at atmospheric pressure).

Results of Liver Retransplantation After Rescue Hepatectomy: A Single-Center Study.

BACKGROUND Liver retransplantation (reLT) is a well-accepted treatment for liver graft failure in selected patients. A rescue hepatectomy (RH), on the contrary, is a rare and controversial procedure in which a deteriorating liver graft causing failure of other organ systems is removed to stabilize the patient's condition before a new liver graft is available. MATERIAL AND METHODS In this retrospective cohort study, we evaluated the outcomes of the 104 patients who were listed for a first single-organ reLT in our center during the period 2000-2019, to compare the results after RH to other reLTs.

Natural deep eutectic solvents as thermostabilizer for Humicola insolens cutinase.

As a new generation of green solvents, deep eutectic solvents (DESs) are considered a promising alternative to current harsh organic solvents and find application in many chemical processing methods such as extraction and synthesis. DESs, normally formed by two or more components via various hydrogen bond interactions, offer high potential as medium for biocatalysis reactions where they can improve efficiency by enhancing substrate solubility and the activity and stability of the enzymes. In the current study, the stabilization of Humicola insolens cutinase (HiC) in natural deep eutectic solvents (NADESs) was assessed.

Dural Tail Sign and Middle Meningeal Artery Hypertrophy in Glioblastoma: A Rarity?

Background: Dural tail sign and increased caliber of branches of the external carotid artery (ECA) are common findings in meningioma and they have been rarely reported in intra-axial lesions. Anyway, some cases of glioblastoma (GBM) are reported in the literature, mostly superficially localized, characterized by these 2 findings and therefore, misdiagnosed with meningioma. The aim of this study is to verify the prevalence of dural tail sign and hypertrophy of middle meningeal artery (MMA) in a large cohort of GBMs.

Targeting the formation of estrogens for treatment of hormone dependent diseases-current status.

Local formation and action of estrogens have crucial roles in hormone dependent cancers and benign diseases like endometriosis. Drugs that are currently used for the treatment of these diseases act at the receptor and at the pre-receptor levels, targeting the local formation of estrogens. Since 1980s the local formation of estrogens has been targeted by inhibitors of aromatase that catalyses their formation from androgens.
