Effects of Replacing Skipped Meals With Oral Nutritional Supplement on Nutritional Status and Physical Function in Older Adults.

Unlabelled: This study evaluated the effects of replacing skipped meals with oral nutritional supplements (ONS) on the nutritional status and functional health of older adults. A total of 29 participants aged ≥ 65 years who regularly skipped at least one meal per day were included in this single-arm study. For 8 weeks, participants consumed two packs of ONS daily (150 mL each, providing 400 kcal and 18 g of protein) as a substitute for skipped meals.

Acupuncture and Herbal Medicine for Nausea and Vomiting in Pregnancy: An Overview and Quality Assessment of Systematic Reviews.

Background: Up to 85% of pregnant women experience nausea and vomiting in pregnancy (NVP), which can impact both the pregnant woman and developing fetus. Traditional East Asian Medicine (TEAM) including acupuncture and herbal medicine has been used to treat NVP; however, its effectiveness remains under debate. This study aimed to systematically review the existing evidence from systematic reviews on the effectiveness of TEAM for NVP and to critically evaluate the quality of these reviews.

Novel Risk Score for 30-Day Adverse Events Following Colonoscopy in Older Adults.

Background/aims: Physicians are challenged with balancing benefits and risks of performing colonoscopies in older adults. We identified adverse event risk factors in this population and developed a predictive risk score for colonoscopy-related adverse events.

Methods: From August 2017 to August 2022, 8,154 patients aged ≥60 years who underwent screening or diagnostic colonoscopies were enrolled at Gangnam Severance Hospital.

Analysis of Retinal Thickness in Patients With Chronic Diseases Using Standardized Optical Coherence Tomography Data: Database Study Based on the Radiology Common Data Model.

Background: The Observational Medical Outcome Partners-Common Data Model (OMOP-CDM) is an international standard for harmonizing electronic medical record (EMR) data. However, since it does not standardize unstructured data, such as medical imaging, using this data in multi-institutional collaborative research becomes challenging. To overcome this limitation, extensions such as the Radiology Common Data Model (R-CDM) have emerged to include and standardize these data types.

High-fat diet triggers transcriptomic changes in the olfactory bulb.

Metabolic imbalance contributes to cognitive impairment, anxiety, depressive behavior, and impaired olfactory perception. Recent studies have focused on olfactory dysfunction in patients with obesity and diabetes accompanied by cognitive dysfunction, considering that the synaptic signal from the olfactory bulb is directly transmitted to memory consolidation-related brain regions. This study investigated transcriptomic changes in the olfactory bulb in high-fat diet (HFD)-fed mice compared to that in normal-diet-fed mice.

Ovarian Cancer and the Microbiome: Connecting the Dots for Early Diagnosis and Therapeutic Innovations-A Review.

Ovarian cancer, which ranks eighth among global female cancers and fifth in fatality, poses a significant health challenge owing to its asymptomatic early stages. Understanding the pathogenesis requires extensive research. Recent studies have emphasized the role of the gut and cervicovaginal microbiota in ovarian cancer.

Oligonol ameliorates liver function and brain function in the 5 × FAD mouse model: transcriptional and cellular analysis.

Alzheimer's disease (AD) is a common neurodegenerative disease worldwide and is accompanied by memory deficits, personality changes, anxiety, depression, and social difficulties. For treatment of AD, many researchers have attempted to find medicinal resources with high effectiveness and without side effects. Oligonol is a low molecular weight polypeptide derived from lychee fruit extract.

The Research of Toxicity and Sensitization Potential of PEGylated Silver and Gold Nanomaterials.

Polyethylene glycol (PEG) is a polymer used for surface modification of important substances in the modern pharmaceutical industry and biopharmaceutical fields. Despite the many benefits of PEGylation, there is also the possibility that the application and exposure of the substance may cause adverse effects in the body, such as an immune response. Therefore, we aimed to evaluate the sensitization responses that could be induced through the intercomparison of nanomaterials of the PEG-coated group with the original group.

Skin Sensitization Potential and Cellular ROS-Induced Cytotoxicity of Silica Nanoparticles.

Nowadays, various industries using nanomaterials are growing rapidly, and in particular, as the commercialization and use of nanomaterials increase in the cosmetic field, the possibility of exposure of nanomaterials to the skin of product producers and consumers is increasing. Due to the unique properties of nanomaterials with a very small size, they can act as hapten and induce immune responses and skin sensitization, so accurate identification of toxicity is required. Therefore, we selected silica nanomaterials used in various fields such as cosmetics and biomaterials and evaluated the skin sensitization potential step-by-step according to in-vitro and in-vivo alternative test methods.

Characterization of the Caenorhabditis elegans HIM-6/BLM helicase: unwinding recombination intermediates.

Mutations in three human RecQ genes are implicated in heritable human syndromes. Mutations in BLM, a RecQ gene, cause Bloom syndrome (BS), which is characterized by short stature, cancer predisposition, and sensitivity to sunlight. BLM is a RecQ DNA helicase that, with interacting proteins, is able to dissolve various DNA structures including double Holliday junctions.

Piperine reverses high fat diet-induced hepatic steatosis and insulin resistance in mice.

This study examined the effect of piperine on hepatic steatosis and insulin resistance induced in mice by feeding a high-fat diet (HFD) for 13 weeks and elucidated potential underlying molecular mechanisms. Administration of piperine (50 mg/kg body weight) to mice with HFD-induced hepatic steatosis resulted in a significant increase in plasma adiponectin levels. Also, elevated plasma concentrations of insulin and glucose and hepatic lipid levels induced by feeding a HFD were reversed in mice when they were administered piperine.

Dietary camphene attenuates hepatic steatosis and insulin resistance in mice.

Objective: The aim of this study was to investigate the protective effects of camphene on high-fat diet (HFD)-induced hepatic steatosis and insulin resistance in mice and to elucidate its mechanism of action.

Design And Methods: Male C57BL/6N mice were fed with a normal diet, HFD (20% fat and 1% cholesterol of total diet), or HFD supplemented with 0.2% camphene (CPND) for 10 weeks.
