Embryos with morphologically non-good-quality blastocytes and those from women aged ≥ 35 years showed lower rates of implantation, clinical pregnancy, ongoing pregnancy, and live births after blastocyst shrinkage. Post-warming blastocyst shrinkage adversely affects ART outcomes.
A new study reveals FGF18 as a key inducer of hepatic stellate cell proliferation and liver fibrosis. FGF18 levels are dramatically elevated in fibrotic livers, and its overexpression induces liver fibrosis in mice.
A recent study found that over 70% of ALS patients and their caregivers are not disaster-prepared, highlighting the need for improved measures. The research also revealed significant gaps in equipment and knowledge among respondents, including ventilator users.
A cross-sectional study in Tokyo, Japan assessed whether information on COVID-19 prevention measures reached the target audience. The study found that eating and drinking services had challenges disseminating accurate information to their staff.
A study published in iScience reveals that fibroblasts cooperate with myeloid cells to produce IL-11, protecting the mucosal epithelium from damage during acute colitis. The interaction between fibroblasts and myeloid cells is crucial for maintaining intestinal homeostasis.
A retrospective study found that multidisciplinary care for ALS significantly decreases multiple emergency hospitalizations and improves survival rates. The study compared patients with ALS treated at a multidisciplinary clinic versus a traditional General Neurology Clinic and showed improved outcomes.
Researchers developed a FRET-based biosensor SMART to visualize necroptosis in living mice, enabling monitoring of this form of regulated cell death in various pathological models. The study successfully characterized necroptosis in vivo using transgenic mice with the FRET biosensor.
Gut epithelial cells control mutualism between host immune system and gut microbiome by regulating SFB and Th17 cell levels. Lack of IκBζ gene impairs defense mechanisms against pathogens, leading to inflammatory diseases.
Researchers developed a new rehabilitation method using filter paper discs to improve taste sensitivity in healthy individuals. The four-step training method increased sensitivity to all four tastes, with significant improvements seen at day 4.
A study investigated the frequency and characteristics of non-motor symptoms in ALS patients, finding over 90% experienced symptoms such as fatigue, pain, and sleep disorders. These symptoms reduced QoL even when motor symptoms were mild, highlighting their importance to consider.
A study led by Toho University identified a glycan structure, Lewis glycans, on the cell surface that makes cancer cells vulnerable to TRAIL-induced death. Cancer cells highly expressing this structure are more sensitive to TRAIL therapy and can serve as a predictive biomarker.
The Hybrid Assistive Limb (HAL) robot has been shown to improve gait ability in patients with amyotrophic lateral sclerosis (ALS), allowing them to walk longer distances with reduced assistance. The therapy sessions, lasting only 20-40 minutes per day for four weeks, also demonstrated preservation of other vital functions.
A new surgical procedure, Conjunctivoductivo-dacryocystorhinostomy, has been developed to treat intractable canalicular obstruction and watery eyes. The procedure creates a new passage for tear fluid to flow, eliminating facial scarring and foreign matter.
A new AI-based scoring model for testis images has been developed to assess patients with severe male infertility, simplifying the diagnosis process. The model achieved high accuracy in classifying histological images of the testis, with an average precision of 82.6% and recall of 60.96%, without requiring programming expertise.
A new study has identified interleukin 11 as a key player in the development of colorectal cancer. IL-11-producing cells, known as cancer-associated fibroblasts, were found to promote tumor growth and support the disease microenvironment.
A new study suggests that Earth's oxygen-rich atmosphere will likely persist for around one billion years, with a high degree of uncertainty. The researchers used a numerical model to simulate climate and biogeochemical processes, finding that the atmosphere will probably decline in oxygen levels due to CO2 scarcity.
Researchers found similar properties between deep neural networks and primate visual cortices, providing insights into attention mechanisms. The study may accelerate AI development by understanding the neural basis of attention.
Researchers found that Mind bomb-2 (MIB2) ubiquitinates and stabilizes the anti-apoptotic protein cFLIP, preventing excessive cell death. This discovery may lead to new therapeutic strategies for treating cancers and neurodegenerative diseases.
Researchers at Toho University found that mice lacking JunB develop severe autoimmune disorders due to reduced Treg cell number. Injecting high doses of IL-2 can mitigate colitis by expanding Treg cells, suggesting a potential novel strategy for treating inflammatory diseases.
