Article Synopsis
  • - The study focused on analyzing the occurrence and timing of growth in subsolid nodules (SSNs) that had been stable for five years, investigating their clinical significance and determining an effective follow-up strategy.
  • - Out of 235 SSNs followed for up to 181 months after initial stability, only 14 (6.0%) showed growth, and no metastases were found, indicating a very low growth incidence.
  • - The proposed follow-up with CT scans every five years post-initial stability could effectively detect most of the growing nodules and any clinical stage shifts.

Infect Dis Ther

December 2024

Institute of Clinical Pharmacy and Pharmaceutical Sciences, College of Medicine, National Cheng Kung University, No.1, University Road, Tainan City, 701, Taiwan.

Article Synopsis
  • This study evaluates how vancomycin is processed in critically ill patients, particularly those undergoing continuous renal replacement therapy (CRRT) or temporary mechanical circulatory support (tMCS).
  • The research involved 25 patients and focused on how factors like serum creatinine and body weight influence drug clearance and distribution.
  • It concludes that vancomycin dosing should consider both renal function and body weight, suggesting modified initial and maintenance doses for patients on CRRT, while also noting that tMCS can complicate dosing adjustments due to altered drug clearance.

Releasing a sugar brake generates sweeter tomato without yield penalty.

Nature

November 2024

National Key Laboratory of Tropical Crop Breeding, Shenzhen Branch, Guangdong Laboratory of Lingnan Modern Agriculture, Genome Analysis Laboratory of the Ministry of Agriculture and Rural Affairs, Agricultural Genomics Institute at Shenzhen, Chinese Academy of Agricultural Sciences, Shenzhen, China.

In tomato, sugar content is highly correlated with consumer preferences, with most consumers preferring sweeter fruit. However, the sugar content of commercial varieties is generally low, as it is inversely correlated with fruit size, and growers prioritize yield over flavour quality. Here we identified two genes, tomato (Solanum lycopersicum) calcium-dependent protein kinase 27 (SlCDPK27; also known as SlCPK27) and its paralogue SlCDPK26, that control fruit sugar content.

Behavioral neuroscience faces two conflicting demands: long-duration recordings from large neural populations and unimpeded animal behavior. To meet this challenge we developed ONIX, an open-source data acquisition system with high data throughput (2 GB s) and low closed-loop latencies (<1 ms) that uses a 0.3-mm thin tether to minimize behavioral impact.

Article Synopsis
  • Weekly artificial insemination (AI) affects stress levels and immune responses in turkey hens throughout their laying cycle, with notable differences observed between hens inseminated with semen and those given only an extender.
  • The study found that semen-inseminated hens had higher stress markers and increased numbers of specific immune cells (like CD3+ T cells) in their reproductive tract by the end of the laying cycle, indicating altered immune activity.
  • Overall, the research highlights that the presence of sperm during AI influences the immune response in the oviduct, suggesting potential avenues for improving reproductive performance in turkey breeding through immune modulation.

Aims: The CHA2DS2VASc score is recommended for stroke risk stratification in patients with atrial fibrillation (AF). This score assigns one extra point to female sex based on evidence from the early 2000s, suggesting higher thromboembolic risk in women. This incremental risk of thromboembolism in women has decreased over time between 2007 and 2018, becoming non-significant in recent years.

A significant challenge for chimeric antigen receptor (CAR) T cell therapy against glioblastoma (GBM) is its immunosuppressive microenvironment, which is densely populated by protumoral glioma-associated microglia and macrophages (GAMs). Myeloid immune checkpoint therapy targeting the CD47-signal regulatory protein alpha (SIRPα) axis induces GAM phagocytic function, but CD47 blockade monotherapy is associated with toxicity and low bioavailability in solid tumors. In this work, we engineer a CAR T cell against epidermal growth factor receptor variant III (EGFRvIII), constitutively secreting a signal regulatory protein gamma-related protein (SGRP) with high affinity to CD47.

Electronic address:

Article Synopsis
  • Immune checkpoint blockade (ICB) can induce tumor ferroptosis, but many patients don't respond because tumors evade this process within the tumor microenvironment (TME).
  • Researchers found that SLC13A3 acts as a transporter for itaconate in tumor cells, contributing to resistance against ferroptosis, which weakens tumor immunity and reduces ICB effectiveness.
  • Targeting SLC13A3 through various methods, like genetic alteration or using a specific inhibitor, can sensitize tumors to ferroptosis, slow down tumor growth, and enhance the effectiveness of ICB treatments, highlighting SLC13A3 as a potential target for cancer therapy.
