Olive oil production generates substantial quantities of pomace, which are often disposed of in soil, leading to adverse effects on agriculture and the environment. Furthermore, climate change exacerbates plant diseases and promotes the use of toxic phytochemicals in agriculture. However, olive mill wastes can have high potential as reusable and valuable bioresources.

The immunization of mice with the sterile culture medium supernatants of (Mtb) H37Rv permitted the production of several monoclonal antibodies (mAbs) specific for secreted and/or released antigens. Two mAbs bound and immunoprecipitated an 80-kDa protein that was identified by mass spectrometry as Rv1133c, the methionine synthase MetE. The protein MetE is ubiquitous among prokaryota and shows a significant sequence homology in many bacteria.

The iron-based KFeSe superconductor displays chemical, structural and electronic phase separation at nanoscale to microscale, leading to the coexisting metallic phase embedded in an antiferromagnetic host matrix. The metallic character of the system is believed to arise from a percolative granular network affecting its transport in the normal as well as in the superconducting state. This percolative network can be manipulated and controlled through thermal treatments.

  • In the TOPAZ-1 trial, patients with biliary tract cancers (BTC) who had recurrence within 6 months of surgery were excluded, which often happens in practice. This study looked into the effectiveness of cisplatin-gemcitabine-durvalumab (CGD) in patients who did experience early recurrence.
  • The study enrolled 178 BTC patients who had surgery and then underwent treatment with CGD after experiencing either early or late disease recurrence. Key goals were to measure overall survival (OS) and progression-free survival (PFS).
  • Results showed no significant differences in OS and PFS between early and late relapse groups, suggesting CGD is effective regardless of when the cancer

Various machine learning (ML) and deep learning (DL) techniques have been recently applied to the forecasting of laboratory earthquakes from friction experiments. The magnitude and timing of shear failures in stick-slip cycles are predicted using features extracted from the recorded ultrasonic or acoustic emission (AE) signals. In addition, the Rate and State Friction (RSF) constitutive laws are extensively used to model the frictional behavior of faults.

  • - Berberine (BBR) is a natural molecule with potential to prevent antibiotic resistance in Gram-negative bacteria, but its effectiveness is limited by poor oral bioavailability and absorption in humans.
  • - The study proposes encapsulating BBR in liposomes, which can improve drug delivery and minimize side effects; experimental and computational methods were used to optimize liposome membrane compositions for better BBR encapsulation.
  • - Results show that using negatively charged lipids, such as cholesteryl hemisuccinate, enhances the efficiency of BBR delivery, providing a new strategy for developing effective treatment systems against antibiotic resistance.

A search for collective effects inside jets produced in proton-proton collisions is performed via correlation measurements of charged particles using the CMS detector at the CERN LHC. The analysis uses data collected at a center-of-mass energy of sqrt[s]=13  TeV, corresponding to an integrated luminosity of 138  fb^{-1}. Jets are reconstructed with the anti-k_{T} algorithm with a distance parameter of 0.

  • The study investigates the associated production of Higgs and W bosons, focusing on how the relative signs of the Higgs couplings to W and Z bosons impact the process.
  • Two specific searches were conducted using large amounts of collision data from the LHC to analyze different coupling scenarios: one for opposite-sign couplings and another for same-sign (standard model-like) couplings.
  • The results significantly exclude the opposite-sign coupling hypothesis and set a strict upper limit on the production rate of this process compared to standard model predictions.

Obesity is a chronic disease associated with increased morbidity and mortality and reduced quality of life. Pharmacotherapy can be associated with life style changes in increasing and maintaining weight loss and ameliorating obesity-related complications and comorbidities. In patients affected by obesity and uncontrolled obesity-associated complications or high degrees of BMI (> 40 Kg/m), metabolic bariatric surgery can be a valid therapeutic option.

Background: Within the framework of sustainable and effective control methods for Aedes albopictus, two different conidial suspensions, BbCS-1 and BbCS-2 (respectively without and with nutrients), were used as solvents for the biopolymers water-soluble 2-hydroxyethylcellulose (HEC) and sodium alginate (SA). In this way, two different classes of hydrogels were prepared for each polymer (previously shown to attract tiger mosquito oviposition) to produce HEC-based and SA-based Bb/Gel systems with and without nutrients. The aim was to achieve a long-lasting and cost-effective lure-and-kill oviposition substrate useful for lethal ovitraps.

Chimeric antigen receptor (CAR) T-cell therapy has achieved notable success in treating hematological cancers but faces significant challenges in solid-tumor treatment and overall efficacy. Key limitations include T-cell exhaustion, tumor relapse, immunosuppressive tumor microenvironments (TME), immunogenicity, and antigen heterogeneity. To address these issues, various genetic engineering strategies have been proposed.

The low-density lipoprotein cholesterol (LDL-C) lowering decreases the risk to develop major adverse cardiovascular events (MACE) in patients with acute coronary syndrome (ACS). Therefore, the "fast track" use of PCSK9 inhibitors (PCSK9i) has been introduced in ACS patients not achieving LDL-C target (70 mg/dl) despite an ongoing lipid lowering therapy with statin at maximum tolerated dosage plus ezetimibe or stain-naïve (LDL-C > 130 mg/dl). PCSK9i "fast track" use has shown to achieve the regression of "non-culprit" atherosclerotic plaques leading to a further MACE decrease.
