Formation and crystalline structure of spherulites from pea and high amylose maize starches.

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.

Administration of AICAR, an AMPK Activator, Prevents and Reverses Diabetic Polyneuropathy (DPN) by Regulating Mitophagy.

Diabetic peripheral neuropathy (DPN) is a common complication of diabetes in both Type 1 (T1D) and Type 2 (T2D). While there are no specific medications to prevent or treat DPN, certain strategies can help halt its progression. In T1D, maintaining tight glycemic control through insulin therapy can effectively prevent or delay the onset of DPN.

Ethical considerations for referral partnerships in clinical research.

Recruitment challenges in clinical research are widespread, particularly for traditionally under-represented groups. Referral relationships-in which research partners and clinical partners agree to collaborate on selected research studies or programmes, with the expectation that the clinical partners refer appropriate patients as potential participants-may help alleviate these challenges. Referral relationships allow research partners access to expanded and more diverse pools of participants by increasing the engagement of medical providers, leveraging providers' connections with patients and providing structural support for study participation.

CAR-T cell therapy in developing countries: how long should we wait?

Low- and middle-income countries (LMICs) face a significant burden of cancer prevalence and incidence. However, the survival rates for patients with cancer in these regions are notably lower than those in high-income countries, primarily due to late diagnosis and limited access to advanced treatments. Chimeric antigen receptor (CAR) T-cell therapy has demonstrated promising outcomes in certain terminally ill patients with cancer, yet access to this treatment remains limited in LMICs, including Nepal.

In order to add to prior research conducted with the scale, this study provides the first formal evaluation of the validity and reliability of the four-item, cancer-focused Information Seeking Experience (ISEE) scale in a cross-sectional, nationally representative health survey of U.

Lentivirus-mediated gene therapy for Fabry disease: 5-year End-of-Study results from the Canadian FACTs trial.

Background: Fabry disease is an X-linked lysosomal storage disorder due to a deficiency of α-galactosidase A (α-gal A) activity. Our goal was to correct the enzyme deficiency in Fabry patients by transferring the cDNA for α-gal A into their CD34+ hematopoietic stem/progenitor cells (HSPCs). Overexpression of α-gal A leads to secretion of the hydrolase; which can be taken up and used by uncorrected bystander cells.

Leisure-Time Physical Activity, Sedentary Behavior, and Biological Aging: Evidence From Genetic Correlation and Mendelian Randomization Analyses.
