The pretherapeutic assessment of axillary lymph node status is crucial in staging early breast cancer patients, significantly influencing their further treatment and prognosis. According to current guidelines, patients with clinically unsuspicious axillary status regularly undergo a biopsy of sentinel lymph nodes (SLNs), whereby metastasis is detected in up to 20% of cases. In recent years, the use of shear wave elastography (SWE) has been studied as an additional ultrasound tool for the non-invasive assessment of tumors in the breast parenchyma and axillary lymph nodes.

December 2024

Neurosurgery, Department of Neuroscience, Psychology, Pharmacology and Child Health, University Hospital of Careggi, University of Florence, 50134 Florence, Italy.

Navigated transcranial magnetic stimulation (nTMS) has seldom been used to study visuospatial (VS) circuits so far. Our work studied (I) VS functions in neurosurgical oncological patients by using repetitive nTMS (rnTMS), (II) the possible subcortical circuits underneath, and (III) the correspondence between nTMS and direct cortical stimulation (DCS) during awake procedures. We designed a monocentric prospective study, adopting a protocol to use rnTMS for preoperative planning, including VS functions for lesions potentially involving the VS network, including neurosurgical awake and asleep procedures.

Objective: Therapeutic interventions for epithelial ovarian cancer (EOC) have increased greatly over the last decade but improvements outside of biomarker selected therapies have been limited. There remains a pressing need for more effective treatment options that can prolong survival and enhance the quality of life of patients with EOC. In contrast to the significant benefits of immunotherapy with immune checkpoint inhibitors (CPI) seen in many solid tumors, initial experience in EOC suggests limited efficacy of CPIs monotherapy.

Sodium MRI can measure sodium concentrations in people with multiple sclerosis, but the extent to which these alterations reflect metabolic dysfunction in the absence of tissue damage or neuroaxonal loss remains uncertain. Increases in total sodium concentration and extracellular sodium concentration are believed to be indicative of tissue disruption and extracellular space expansion. Conversely, increase in intracellular sodium concentration may represent early and transient responses to neuronal insult, preceding overt tissue damage.

The oxidation of Met residues in proteins is a complex process, where protein-specific structural and dynamical features play a relevant role in determining the reaction kinetics. Aiming to a full-side perspective, we report here a comprehensive characterization of Met oxidation kinetics by hydrogen peroxide in a leptin protein case study. To do that, we estimated the reaction-free energy profile of the Met oxidation via a QM/MM approach, while the kinetics of the formation of the reactive species were calculated using classical molecular dynamics (MD) simulations.

January 2025

Department of Orthopedic Surgery, NYU Langone Health, New York, NY.

Article Synopsis
  • The study analyzed preoperative data from adult spinal deformity patients to establish a threshold for T1 slope (T1S) from cervical radiographs that indicates thoracolumbar malalignment.
  • Researchers found a specific cutoff of 30 degrees for high T1S, with 50% of the patients falling above this threshold.
  • Notably, higher T1S was linked with greater thoracic kyphosis, sagittal vertical axis, T1-pelvic angle, and pelvic tilt, suggesting that this measurement could serve as a useful parameter in cervical evaluations.

De novo discovery of cyclic peptide inhibitors of IL-11 signaling.

Bioorg Med Chem

November 2024

Takeda Development Center Americas, Inc., 9625 Towne Centre Drive, San Diego, CA 92121, USA.

Interleukin-11 (IL-11), a member of the IL-6 cytokine family, has potential pro-inflammatory and pro-fibrotic roles in pulmonary, hepatic, cardiovascular, renal and intestinal disease pathogenesis, including oncogenesis. The potential for therapeutic intervention in these disease spaces has therefore made the IL-11 signaling axis an attractive target in drug discovery, and antibody inhibitors of IL-11 signaling are currently under evaluation in Phase I/II clinical trials. While lower molecular weight small molecule and peptide inhibitors may offer the potential for improved tissue penetration, developability and manufacturing cost compared with a protein therapeutic, reports of such chemical matter in the literature are limited.

FBP1 controls liver cancer evolution from senescent MASH hepatocytes.

Nature

January 2025

Laboratory of Gene Regulation and Signal Transduction, Departments of Pharmacology and Pathology, School of Medicine, University of California San Diego (UCSD), La Jolla, CA, USA.

Article Synopsis
  • Hepatocellular carcinoma (HCC) arises from liver cells (hepatocytes) that are damaged and undergoing compensatory growth, particularly due to metabolic disorders like MASH.
  • The tumor-suppressive effects of p53 and the anti-cancer role of the enzyme FBP1 are undermined in HCC, as FBP1 is commonly degraded and suppressed in tumors.
  • Key metabolic pathways involving AKT and NRF2 play a role in reversing the effects of cellular senescence, boosting the growth of HCC cells and leading to the accumulation of genetic mutations that contribute to cancer progression.

Article Synopsis
  • Endoscopic-assisted breast surgery (EABS) offers better cosmetic results for breast cancer patients, but traditional axillary lymph node dissection (ALND) requires larger incisions and more retraction.
  • The proposed single-port three-dimensional endoscopic-assisted ALND (S-P 3D E-ALND) uses a minimally invasive technique with high success rates and improved visualization, analyzed from a study of 11 patients.
  • Preliminary results show 100% success without open surgery conversion, short operative times, minimal blood loss, and no significant complications over a median follow-up of 7 months, suggesting that S-P 3D E-ALND is a viable alternative for ALND.

The N1 auditory evoked potential amplitude depends heavily on the inter-stimulus interval (ISI). Typically, shorter ISIs result in reduced N1 amplitudes, suggesting a decreased neural response with high stimulus presentation rates. However, an exception known as N1 facilitation occurs with very brief ISIs (∼150-500 ms), where the N1 amplitude increases.
