Intestinal stem cells in intestinal homeostasis and colorectal tumorigenesis.

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.

Integrated transcriptomic analysis reveals dysregulated immune infiltration and pro-inflammatory cytokines in the secretory endometrium of recurrent implantation failure patients.

Recurrent implantation failure (RIF) is a leading impediment to assisted reproductive technology, yet the underlying pathogenesis of RIF remains elusive. Recent studies have sought to uncover novel biomarkers and etiological factors of RIF by profiling transcriptomes of endometrial samples. Nonetheless, the inherent heterogeneity among published studies and a scarcity of experimental validations hinder the identification of robust markers of RIF.

Physical symptoms distress and demoralization among haemodialysis patients; the mediating effect of spirituality and self-compassion. A cross-sectional questionnaire survey.

Background: Long-term haemodialysis patients often experience physical symptom distress (PSD) and varying levels of demoralization. Spirituality and self-compassion can help patients to cope these challenges. However, the interrelations between these variables remain underexplored, necessitating further investigation.

Objective: To analyze the degree of technological acceptance and use within nurses in two Latin American university hospitals.

Autotransplantation of a Third Molar to Replace Compromised Molar With the Individual Three-Dimensional Printed Ultrasonic Osteotome: A Case Report.

Tooth autotransplantation is widely used to replace congenitally missing teeth or teeth with irreversible damage. This case report presents a personalized ultrasonic osteotome that enables precise preparation, minimizes bone trauma, enhances the initial stability of the transplanted tooth, and contributes to a favorable prognosis. The procedure is as follows: a 25-year-old female patient presented with a porcelain-fused-to-metal crown on Tooth #19, which had detached due to severe decay, rendering the tooth unsalvageable.

Population imaging of internal state circuits relevant to psychiatric disease: a review.

Internal states involve brain-wide changes that subserve coordinated behavioral and physiological responses for adaptation to changing environments and body states. Investigations of single neurons or small populations have yielded exciting discoveries for the field of neuroscience, but it has been increasingly clear that the encoding of internal states involves the simultaneous representation of multiple different variables in distributed neural ensembles. Thus, an understanding of the representation and regulation of internal states requires capturing large population activity and benefits from approaches that allow for parsing intermingled, genetically defined cell populations.

When synthetic biology meets medicine.

In recent years, the world has faced significant challenges with the coronavirus disease 2019 (COVID-19) pandemic, as well as other infectious diseases such as Zika and Ebola. Furthermore, the rapid rise of non-communicable diseases such as diabetes, heart disease, and cancer has placed tremendous strain on healthcare resources and systems. Unfortunately, advancements in drug development, diagnostics, and therapeutics have struggled to keep pace with the emergence and progression of diseases, necessitating the exploration of new technologies for the discovery and development of biomedicines and biotherapies.

Follicular fluid-derived exosomes rejuvenate ovarian aging through miR-320a-3p-mediated FOXQ1 inhibition.

Ovarian aging is mainly characterized by a progressive decline in oocyte quantity and quality, which ultimately leads to female infertility. Various therapies have been established to cope with ovarian aging, among which exosome-based therapy is considered a promising strategy that can benefit ovarian functions via multiple pathways. Here, we isolated and characterized exosomes derived from ovarian follicular fluid and profiled the differential expression patterns of noncoding exosomal RNAs in young and aged women.

A biomarker framework for liver aging: the Aging Biomarker Consortium consensus statement.

In human aging, liver aging per se not only increases susceptibility to liver diseases but also increases vulnerability of other organs given its central role in regulating metabolism. Total liver function tends to be well maintained in the healthy elderly, so liver aging is generally difficult to identify early. In response to this critical challenge, the Aging Biomarker Consortium of China has formulated an expert consensus on biomarkers of liver aging by synthesizing the latest scientific literature, comprising insights from both scientists and clinicians.

Brensocatib in patients with bronchiectasis: subgroup analyses from the WILLOW trial.

Introduction: Bronchiectasis is a chronic inflammatory airway disease. Brensocatib, an oral, reversible inhibitor of dipeptidyl peptidase 1 (DPP1), reduces pulmonary inflammation by preventing the activation of neutrophil serine proteases. In the phase II WILLOW trial, brensocatib prolonged time to first exacerbation in patients with bronchiectasis.

The gut microbiome and cross-reactivity of food allergens: current understanding, insights, and future directions.

This mini-review examines the emerging role of the gut microbiome in influencing food allergen cross-reactivity. It specifically focuses on how microbial diversity, antigens, and metabolites impact IgE-mediated allergic responses. Cross-reactivity occurs when structurally similar food and microbial antigens trigger hypersensitivities, affecting millions of people worldwide.

Nurses' Experience With End-of-Life Care in Geriatric Centers: A Systematic Review.

Background: Geriatric nurses provide end-of-life care based on the five pillars of aging. This systematic review assesses the emotions and feelings of geriatric nurses during end-of-life care. It considers the prevalence, triggers, and intensity of emotional responses among geriatric nurses.

Biochemical mechanisms and molecular interactions of vitamins in cancer therapy.

Recently, the potential role of vitamins in cancer therapy has attracted considerable research attention. However, the reported findings are inconsistent, with limited information on the biochemical and molecular interactions of different vitamins in various cancer cells. Importantly, the presence of vitamin receptors in tumor cells suggests that vitamins play a significant role in the molecular and biochemical interactions in cancers.

Integrative analysis of cuproptosis-related lncRNAs: Unveiling prognostic significance, immune microenvironment, and copper-induced mechanisms in prostate cancer.

Background: Long non-coding ribonucleic acids (lncRNAs) regulate messenger RNA (mRNA) expression and influence cancer development and progression. Cuproptosis, a newly discovered form of cell death, plays an important role in cancer. Nonetheless, additional research investigating the association between cuproptosis-related lncRNAs and prostate cancer (PCa) prognosis is required.

Loss of phosphatase and tensin homolog () increases Lysyl oxidase-like 2 () expression enhancing the growth of fallopian tube epithelial cells as three-dimensional spheroids.

Background: High-grade serous ovarian cancer (HGSOC) accounts for 70-80% of all ovarian cancer-related deaths. Multiple studies have suggested that the fallopian tube epithelium (FTE) serves as the cell of origin of HGSOC. Phosphatase and tensin homolog () is a tumor suppressor and its loss is sufficient to induce numerous tumorigenic changes in FTE, including increased migration, formation of multicellular tumor spheroids (MTSs), and ovarian colonization.
