Resistant starch (RS) has been shown to modulate intestinal microbiota in animal models in ways that could reduce the effects of dysbiosis-related diseases. However, the mechanism of how this is achieved is not understood. The present study aimed to reveal the mechanism of how RS mitigates dextran sulfate sodium (DSS)-induced colitis in mice by using a starch-lipid complex (RS type 5), with an RS type 2 from high-amylose maize starch as a comparison.

The effects of complexing conditions on the formation of amylose-lipid-protein complexes and relationships between structure and digestion of amylose-lipid and amylose-lipid-protein complexes were poorly understood. The objective of this study was to investigate the effects of complexing time (0, 0.5, 2, 4 and 6 h) and temperature (60, 70, 80, 90 and 100 °C) on the structure and in vitro amylolysis of amylose-lauric acid (AM-LA) and amylose-lauric acid-β-lactoglobulin (AM-LA-βLG) complexes, and to understand the relationships between structure and in vitro digestiblity of these complexes.

Slow-digesting starch with bioactive functionality has been attracting much interest with the increasing incidence of type-2 diabetes and other diet-related illnesses. The present study demonstrates a simple method for preparing a starch inclusion complex with reduced enzymic digestion and enhanced antioxidant activities using debranched pea starch (PS) and 10-gingerol (10G). Enzymically debranched starch complexed more 10G and formed more structurally ordered starch-10G complexes compared to PS that had not been debranched.

Objective: To identify characteristics associated with long-term progression-free survival (≥2 years) in patients with advanced ovarian cancer treated with niraparib first-line maintenance therapy in the phase III PRIMA/ENGOT-OV26/GOG-3012 study.

Methods: In this post hoc analysis of PRIMA, patients randomized to niraparib were grouped based on investigator-assessed progression-free survival (progressive disease/censoring <2 years or ≥2 years after randomization). Variables assessed for predictive value were Eastern Cooperative Oncology Group performance status, International Federation of Gynecology and Obstetrics (FIGO) stage at diagnosis, clinical response to platinum-based chemotherapy, number of prior chemotherapy cycles, primary tumor location, body mass index, categorical age, debulking surgery type, number of baseline target lesions, number of baseline non-target lesions, /homologous recombination-deficiency status, residual disease status, and duration from end of chemotherapy to randomization.

Article Synopsis
  • Structural factors affecting how starch-lipid complexes break down have been unclear, but understanding this relationship is key for creating complexes with predictable digestibility.
  • This study examined how different temperatures and times influenced the formation and stability of complexes made from debranched high-amylose starch and various fatty acids, revealing that higher temperatures and longer times generally increased stability.
  • Molecular dynamics simulations indicated that DHAMS-lauric acid complexes were less stable than others due to lower binding free energy, and overall, the rate of enzyme digestion of these starch-lipid complexes was slower compared to gelatinized starch, primarily linked to the perfection of their crystallites.

With the increasing number of diabetic patients in the world, there is an urgent requirement to reduce the incidence of diabetes. It is considered that a viable prophylactic treatment for type 2 diabetes mellitus is to reduce starch digestibility and oxidative stress. In this study, a novel type of slowly digested starch [pea starch (PS)-gingerol complex] was fabricated to evaluate its in vitro enzymatic digestibility and antioxidant activities.

A quantitative method was developed to characterize the short-range order in non-crystalline starch by Raman spectroscopy. The Raman spectra of three forms of non-crystalline starches (just-gelatinized starch, which was heated to the point of having just lost its long-range order but still retaining essentially all of its short-range order, gelatinized starch and amorphous starch) were resolved into subspectra to calculate the short-range ordered phases. By deducting the spectra of amorphous starch using a subtraction technique, the areas of subspectra for short-range ordered phases in just-gelatinized and gelatinized starches were obtained.

Article Synopsis
  • This study examined how donor heart characteristics, specifically left ventricular ejection fraction (EF) and wall thickness (LVWT), affect survival rates in heart transplant (HTx) recipients using data from the UNOS registry between 2006-2022.
  • A total of 21,012 adult HTx recipients were analyzed, separated into four groups based on donor EF and LVWT, revealing no significant differences in mortality rates at 30 days, 1 year, or 5 years.
  • The findings suggest that broadening donor selection criteria could help increase the donor pool and potentially lower waitlist mortality for those needing heart transplants.

Article Synopsis
  • The study looked at how well different combinations of drugs work for treating a type of ovarian cancer that comes back after treatment.
  • Researchers compared patients who received a specific drug combination called carboplatin and pegylated liposomal doxorubicin with those who got other drug combinations before they started maintenance therapy with a drug called PARP inhibitor.
  • The results showed that, although there were some differences in how long patients stayed cancer-free, the overall survival times were not significantly different, meaning more research is needed to understand which drug combination is better.

A model system of gelatinized wheat starch (GWS) and lauric acid (LA) was used to examine the effect of residual short-range molecular order in GWS on the formation of starch-lipid complexes. The extent of residual short-range molecular order, as determined by Raman spectroscopy, decreased with increasing water content or heating duration of gelatinization. The enthalpy changes, crystallinity, short-range molecular order and the in vitro enzymic digestion of GWS-LA complexes increased initially to a maximum and then declined as the short-range molecular order in GWS decreased, showing that there was an optimal amount of residual short-range molecular order in GWS for maximizing GWS-LA complexes formation.

Currently, the prevalence of autism spectrum disorder (henceforth "autism") is 1 in 36, an increasing trend from previous estimates. In 2015, the United States adopted a new version (International Classification of Diseases, 10th Revision) of the World Health Organization coding system, a standard for classifying medical conditions. Our goal was to examine how the transition to this new coding system impacted autism diagnoses in 10 healthcare systems.
