Laetrile, known as vitamin B17, is often used interchangeably with amygdalin. Laetrile is a semi-synthesis product of amygdalin, whereas amygdalin is a naturally occurring substance in many plants. Both compounds have a nitrile functional group that, when activated by the intestinal enzyme β-glucosidases, releases hydrogen cyanide.

Light metal-based nanomaterials are widely used for energy storage due to their high energy density and surface-to-volume ratio. However, their high reactivity is paradoxically both the source of advantageous properties and a hurdle to the fabrication of stable nanostructures. Here, we demonstrate the formation of nanoporous Mg via chemical redox agent-driven dealloying, which ensures minimized surface passivation and results in fine nanostructures with <50 nm of interconnected metallic ligament despite the labile chemical properties of Mg.

Background/purpose: The occurrence of post-vital pulp therapy (VPT) symptoms is perplexing for dentists, and root canal treatment (RCT) is preferred for such conditions. Furthermore, managing post-VPT symptoms, rather than performing RCT, would preserve pulp vitality and enhance VPT outcomes. This study aimed to evaluate the efficacy of VPT retrials in preserving pulp vitality and substituting RCT in teeth with post-VPT symptoms.

Background/purpose: Chewing difficulty can contribute to psychological stress, which reduces the quality of life for older adults. The purpose of this study was to investigate and analyze the severity of masticatory discomfort, stress response, and sleep disturbance in older patients experiencing masticatory discomfort due to tooth loss or temporomandibular disorders (TMD), to find the further treatment direction for these patients.
Materials And Methods: A total of 392 patients aged 50 years and older with mastication difficulties were analyzed.

Hemangiosarcoma is a highly malignant tumor commonly affecting canines, originating from endothelial cells that line blood vessels, underscoring the importance of early detection. This canine cancer is analogous to human angiosarcoma, and the development of liquid biopsies leveraging cell-free DNA (cfDNA) represents a promising step forward in early cancer diagnosis. In this study, we utilized Whole Genome Sequencing (WGS) to analyze fragment sizes and copy number alterations (CNAs) in cfDNA from 21 hemangiosarcoma-affected and 36 healthy dogs, aiming to enhance early cancer detection accuracy through machine learning models.

Colorectal cancer (CRC), one of the most common tumors in the world, is generally proposed to be generated from intestinal stem cells (ISCs). Leucine-rich repeat-containing G protein-coupled receptor 5 (Lgr5)-positive ISCs are located at the bottom of the crypt and harbor self-renewal and differentiation capacities, serving as the resource of all intestinal epithelial cells and CRC cells as well. Here we review recent progress in ISCs both in non-tumoral and tumoral contexts.

Immune checkpoint inhibitors (ICIs) use antibodies that block cell surface immune checkpoint proteins with great efficacy in treating immunogenic or "immune hot" tumors such as melanoma, kidney, and lung adenocarcinoma. ICIs have limited response rates to other non-immunogenic cancers. The tumor microenvironment (TME) consists of many cell types that collectively promote tumor progression.

The human gut, which contains a diverse microbiome, plays an important role in maintaining physiological balance and preserving the immune system. The complex interplay between the central nervous system (CNS) and the gut microbiome has gained significant attention due to its profound implications for overall health, particularly for gut and brain disorders. There is emerging evidence that the gut-brain axis (GBA) represents a bidirectional communication system between the CNS and the gastrointestinal tract and plays a pivotal role in regulating many aspects of human health.
