Starch spherulite is a unique form of resistant starch characterized by a spherical structure with crystalline lamellae that are radially oriented and may find applications in delivery of nutrients and bioactives to the lower gastrointestinal tract. Formation of starch spherulites generally requires heating to a high temperature followed by quenching and long crystallization time. The objectives of this study were to gain a deeper understanding of the factors influencing spherulite formation from pea starch (PS) and high-amylose maize starch (HAMS) and investigate if spherulites could be formed by a slow cooling rate and determine the crystalline structure and morphology of the spherulites formed.

Background And Objective: The white blood cell-to-haemoglobin ratio (WHR) is a comprehensive indicator of inflammation and anaemia status. However, the relationship between the WHR and the risk of 30-day mortality among intensive care unit (ICU) patients with pulmonary hypertension (PH) remains unclear. The purpose of this study was to investigate the association between the WHR and 30-day mortality in critically ill patients with PH.

Article Synopsis
  • - Ficolins are proteins linked to immune system function and are being studied in relation to interstitial lung diseases, particularly focusing on ficolin-1's unclear role in pulmonary fibrosis.
  • - Research found that ficolin-1 levels are lower in patients with idiopathic pulmonary fibrosis (IPF) and connective tissue disease-related interstitial lung disease (CTD-ILD), and in a mouse model, lack of ficolin-B worsened lung damage while overproduction helped protect against it.
  • - Ficolin-1 directly interacts with TGF-β1, a key factor in fibrosis, suggesting that targeting ficolin-1 could provide new therapeutic options for treating lung fibrosis.

Article Synopsis
  • Metabolic dysfunction-associated steatohepatitis (MASH) is a serious health concern and a severe form of liver disease, but progress in finding effective drugs has been slow, with only one drug approved recently.
  • The review discusses the challenges faced in current clinical trials for MASH, such as low drug response rates and poor trial designs, which make drug development difficult.
  • It highlights the importance of integrating MASH treatment with management of related conditions and suggests that exploring non-invasive testing and combination therapies could lead to better treatment options for patients.

Article Synopsis
  • - The study focused on modifying high-amylose maize starch by debranching it to enhance linear molecule formation and create spherulites, which are specific crystalline structures.
  • - After heating the starch at 180 °C and crystallizing it at various temperatures, researchers found that crystallization at 150 °C resulted in less stable spherulites with negative birefringence, indicating molecular degradation and reduced digestion resistance.
  • - In contrast, spherulites crystallized at temperatures between 25 to 120 °C displayed strong positive birefringence, a more stable structure, and high levels of resistant starch, as α-amylase could not penetrate these structures effectively.

Background: The potential impact of pre-existing coronary artery stenosis (CAS) on acute pulmonary embolism (PE) episodes remains underexplored. This study aimed to investigate the association between pre-existing CAS and the elevation of high-sensitivity cardiac troponin I (hs-cTnI) levels in patients with PE.

Methods: In this multicenter, prospective case-control study, 88 cases and 163 controls matched for age, sex, and study center were enrolled.

Lung squamous cell carcinoma (LSCC) is a deadly cancer in the world. Histone demethylase Jmjd2c is a key epigenetic regulator in various tumors, while the molecular mechanism underlying Jmjd2c regulatory in LSCC is still unclear. We used the aldehyde dehydrogenasebright (ALDH) subtype as a research model for cancer stem cells (CSCs) in LSCC and detected the sphere formation ability and the proportion of ALDH CSCs with Jmjd2c interference and caffeic acid (CA) treatment.

Background: Rapamycin has been extensively utilized for coating coronary artery stents to reduce the occurrence of restenosis, yet there has been limited research on the potential harms of rapamycin-eluting stents. Herein, We report a case of eosinophilia and interstitial pneumonia caused by a cobalt-based alloy stent eluted with rapamycin.

Case Presentation: The patient was admitted due to fever, cough, and expectoration symptoms.

Background: With the implementation of the 11th edition of the International Classification of Diseases (ICD-11) and the publication of the metabolic dysfunction-associated fatty liver disease (MAFLD) nomenclature in 2020, it is important to establish consensus for the coding of MAFLD in ICD-11. This will inform subsequent revisions of ICD-11.

Methods: Using the Qualtrics XM and WJX platforms, questionnaires were sent online to MAFLD-ICD-11 coding collaborators, authors of papers, and relevant association members.

Chitin nanofibrils (ChNF) sourced from discarded marine biomass are shown as effective stabilizers of carbon nanomaterials in aqueous media. Such stabilization is evaluated for carbon nanotubes (CNT) considering spatial and temporal perspectives by using experimental (small-angle X-ray scattering, among others) and theoretical (atomistic simulation) approaches. We reveal that the coassembly of ChNF and CNT is governed by hydrophobic interactions, while electrostatic repulsion drives the colloidal stabilization of the hybrid ChNF/CNT system.

Maintaining food safety and quality is critical for public health and food security. Conventional food preservation methods, such as pasteurization and dehydration, often change the overall organoleptic quality of the food products. Herein, we demonstrate a method that affects only a thin surface layer of the food, using beef as a model.

Landslide susceptibility assessment (LSA) is fundamental for managing landslide geological disasters. This study presents a deep learning approach (DNN-MSFM) designed to enhance LSA modeling, particularly addressing limitations caused by the unbalanced distribution of data samples in applied datasets. DNN-MSFM approach combines a deep neural network (DNN) and a mean squared false misclassification loss function (MSFM) to handle unbalanced samples from the algorithmic perspective.

Recently, hydrogel-based soft materials have demonstrated huge potential in soft robotics, flexible electronics as well as artificial skins. Although various methods are developed to prepare tough and strong hydrogels, it is still challenging to simultaneously enhance the strength and toughness of hydrogels, especially for protein-based hydrogels. Herein, a biomimetic "salting out-alignment-locking" tactic (SALT) is introduced for enhancing mechanical properties through the synergy of alignment and the salting out effect.

Drug-induced liver injury (DILI) is an important adverse drug reaction that can lead to acute liver failure or even death in severe cases. Currently, the diagnosis of DILI still follows the strategy of exclusion. Therefore, a detailed history taking and a thorough and careful exclusion of other potential causes of liver injury is the key to correct diagnosis.

Azarshahr County in the northwest of Iran is predominantly covered by Azarshahr travertine, a prevailing sedimentary rock. This geological composition has led to extensive open-pit mining activities, particularly in the western and southwestern parts of the county. The rock's drillability and resistance to excavation play a pivotal role in determining its overall durability and hardness, crucial factors that influence the mining process.
