Genome-wide association meta-analysis identifies two novel loci associated with dental caries.

Background: Tooth loss significantly impacts oral function and overall health deterioration. Dental caries and periodontal disease are major contributors to tooth loss, emphasizing the critical need to prevent these conditions. Genetic studies have played a crucial role in deepening our understanding of the underlying mechanisms of these diseases.

Efficacy of hard gummy candy chewing in improving masticatory function in Japanese children aged 6-12 years: A clinical trial.

Objectives: Japanese children have been shown to exhibit decreased masticatory function; however, limited evidence is available regarding the efficacy of certain food items in improving this issue. Therefore, this study examined the effects of chewing hard gummy candy on the masticatory function of Japanese children aged 6-12 years.

Methods: The study included 26 participants (10 boys and 16 girls; mean age ± standard error = 9.

Decreased Frequency of Mental Workload-Induced Subjective Hot Flashes Through Gum Massage: An Open-Label, Self-Controlled Crossover Trial.

Objective: Hot flashes, a symptom of menopause, can decrease women's quality of life. Sympathetic nervous system activation has been identified as an important factor in the occurrence of hot flashes. Given that somatosensory stimulation of the oral cavity can affect autonomic nervous activity, we aimed to investigate the possibility that somatosensory stimulation of the gums (, gum massage) could improve hot flashes.

The inhibitory effects of toothpaste and mouthwash ingredients on the interaction between the SARS-CoV-2 spike protein and ACE2, and the protease activity of TMPRSS2 in vitro.

SARS-CoV-2 enters host cells when the viral spike protein is cleaved by transmembrane protease serine 2 (TMPRSS2) after binding to the host angiotensin-converting enzyme 2 (ACE2). Since ACE2 and TMPRSS2 are expressed in the tongue and gingival mucosa, the oral cavity is a potential entry point for SARS-CoV-2. This study evaluated the inhibitory effects of general ingredients of toothpastes and mouthwashes on the spike protein-ACE2 interaction and the TMPRSS2 protease activity using an in vitro assay.

Effects of aerobic, resistance, and mixed exercises on quality of life in patients with cancer: A systematic review and meta-analysis.

Background: Quality of life has multiple aspects, but little is known about the effects of exercise on each domain of it. This systematic review aimed to determine the effects of aerobic, resistance, and mixed exercise on multiple aspects of quality of life in patients with cancer through a meta-analysis.

Methods: Randomized controlled trials with quality of life were collected, and 20 studies were analyzed.

Effects of transcutaneous electrical nerve stimulation on physical symptoms in advanced cancer patients receiving palliative care.

Transcutaneous electrical nerve stimulation (TENS) is primarily used for pain, but might be useful for various other physical symptoms, including nausea, fatigue, dyspnea, and constipation. However, few studies have used TENS for treating the physical symptoms of patients with advanced cancer. In this crossover trial, we assess the effects of TENS on pain and other physical symptoms in 20 in-patients with advanced cancer receiving palliative care.

Naldemedine-induced Opioid Withdrawal Syndrome in a Patient with Breast Cancer without Brain Metastasis.

Opioid-induced-constipation (OIC) can be treated by naldemedine and other peripherally acting mu-opioid receptor antagonists (PAMORA) via a novel mechanism. We describe the case of a 52-year-old female outpatient who developed OIC while receiving oxycodone for pain due to cancer with multiple bone metastases. Although she did not have brain metastasis, opioid withdrawal syndrome (OWS) developed after taking naldemedine orally.

Novel effects of rooibos extract on tear and saliva secretion mediated by the muscarinic acetylcholine receptor 3 in mice.

Objectives: Sicca syndrome is characterized by dry mouth and eyes and results in a reduction of the patient's quality of life. Various natural plants, including certain herbs, have long been employed to alleviate such symptoms. Rooibos grown in South Africa is one of the potent herbal plants used for the treating dry mouth.

Effects of Aerobic and Resistance Exercises on Physical Symptoms in Cancer Patients: A Meta-analysis.

Objective: This study aimed to conduct a meta-analysis to establish the effect of exercise interventions on physical symptoms, including fatigue, nausea/vomiting, pain, dyspnea, insomnia, loss of appetite, constipation, and diarrhea in cancer patients and survivors.

Methods: We searched articles published before April 2017 using the following databases: Cochrane Library, PubMed/MEDLINE, CINAHL, Scopus, PEDro, Health & Medical Collection, and Psychology Database. Randomized controlled trials (RCTs) of exercise intervention in cancer patients, which evaluated cancer-related physical symptoms using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-C30, were included.

Bovine lactoferrin promotes energy expenditure via the cAMP-PKA signaling pathway in human reprogrammed brown adipocytes.

Lactoferrin (LF) is a multifunctional protein in mammalian milk. We previously reported that enteric-coated bovine LF reduced the visceral fat in a double-blind clinical study. We further demonstrated that bovine LF (bLF) inhibited adipogenesis and promoted lipolysis in white adipocytes, but the effect of bLF on brown adipocytes has not been clarified.

Lactoferrin interacts with bile acids and increases fecal cholesterol excretion in rats.

Lactoferrin (LF) is a multifunctional cationic protein (pI 8.2-8.9) in mammalian milk.

Enteric lactoferrin attenuates the development of high-fat and high-cholesterol diet-induced hypercholesterolemia and atherosclerosis in Microminipigs.

Previously, we found that enteric lactoferrin (eLF) could reduce the visceral fat accumulation known to associate strongly with metabolic syndrome symptoms and consequently with an increased risk of atherosclerosis. In this study, the atherosclerosis-preventive potential of LF was assessed in a high-fat and high-cholesterol diet (HFCD)-induced hypercholesterolemia and atherosclerosis model using Microminipig™. Eight-week orally administered eLF remarkably reduced the HFCD-induced serum total and low-density lipoprotein cholesterol levels but not high-density lipoprotein cholesterol levels.

Role of LRP1 and ERK and cAMP Signaling Pathways in Lactoferrin-Induced Lipolysis in Mature Rat Adipocytes.

Lactoferrin (LF) is a multifunctional glycoprotein present in milk. A clinical study showed that enteric-coated bovine LF tablets decrease visceral fat accumulation. Furthermore, animal studies revealed that ingested LF is partially delivered to mesenteric fat, and in vitro studies showed that LF promotes lipolysis in mature adipocytes.

Lactoferrin attenuates fatty acid-induced lipotoxicity via Akt signaling in hepatocarcinoma cells.

Nonalcoholic fatty liver disease (NAFLD) describes a spectrum of lesions ranging from simple steatosis to non-alcoholic steatohepatitis (NASH). The excess influx of fatty acids (FAs) into the liver is recognized as a main cause of simple steatosis formation and progression to NASH. Recently, administration of lactoferrin (LF), a glycoprotein present in milk, was suggested to prevent NAFLD development.

Potent lipolytic activity of lactoferrin in mature adipocytes.

Lactoferrin (LF) is a multifunctional glycoprotein found in mammalian milk. We have shown in a previous clinical study that enteric-coated bovine LF tablets decreased visceral fat accumulation. To address the underlying mechanism, we conducted in vitro studies and revealed the anti-adipogenic action of LF in pre-adipocytes.

Bovine lactoferrin reduces visceral fat and liver triglycerides in ICR mice.

Lactoferrin (LF) is a multi-functional glycoprotein found in milk. In a previous clinical trial, we showed that enteric-coated bovine LF (bLF) tablets could reduce visceral fat accumulation. We also showed that bLF had anti-adipogenic activity in vitro.

Effects of Enteric-coated Lactoferrin Tablets Containing Lactobacillus brevis subsp. coagulans on Fecal Properties, Defecation Frequency and Intestinal Microbiota of Japanese Women with a Tendency for Constipation: a Randomized Placebo-controlled Crossover Study.

The effects of oral administration of enteric-coated tablets containing lactoferrin (LF; 100 mg/tablet) and heat-killed Lactobacillus brevis subsp. coagulans FREM BP-4693 (LB; 6×10(9) bacteria/tablet) on fecal properties were examined in 32 Japanese women (20-60 years of age) with a tendency for constipation (defecation frequency at equal to or less than 10 times/2 weeks) by a double-blind placebo-controlled crossover design. A significant increase in defecation days per week was obserbed in the subjects who ingested the tablets containing LF and LB compared with the placebo group.

Effects of pepsin and trypsin on the anti-adipogenic action of lactoferrin against pre-adipocytes derived from rat mesenteric fat.

Lactoferrin (LF) is a multifunctional glycoprotein in mammalian milk. In a previous report, we showed that enteric-coated bovine LF tablets can decrease visceral fat accumulation, hypothesising that the enteric coating is critical to the functional peptides reaching the visceral fat tissue and exerting their anti-adipogenic activity. The aim of the present study was to assess whether ingested LF can retain its anti-adipogenic activity.

Establishment of a primary culture method for mouse intestinal epithelial cells by organ culture of fetal small intestine.

Studies of the physiological functions of intestinal epithelial cells (IECs) have been limited by the difficulty of primary culture of IEC. We established a method for primary culture of mouse IEC by culturing fragments of fetal small intestines pretreated with EDTA. This method reproducibly resulted in the expansion of cytokeratin-positive epithelial cells, and vigorous expansion of the epithelial cells was observed only from intestinal fragments of embryonic days 15-16.
