Effect of infusion time on risk of bloodstream infections in patients administered with BFLUID amino acid infusions via peripheral venous catheters.

Comprehensive electrolyte infusions containing amino acids, including BFLUID, are a source of nosocomial infections caused by . It is recommended that clinicians finish the administration of BFLUID within 6 h; however, this recommendation currently lacks supporting empirical evidence. Accordingly, the present study aimed to investigate the risk of infection associated with BFLUID infusion according to the administration time.

Smoking-induced suppression of β-casein in milk is associated with an increase in miR-210-5p expression in mammary epithelia.

Smoking during lactation harmfully affects the amount and constituents of breast milk. Infants who consume breast milk containing miR-210-5p may have a higher risk of brain-related diseases. We investigated whether smoking during lactation decreases β-casein concentrations in milk and whether miR-210-5p expression is involved in smoking-induced β-casein suppression.

Pork Liver Decomposition Product May Improve Frontal Lobe Function in Humans-Open Trial.

Porcine Liver Decomposition Product (PLDP) was obtained by treating pig liver homogenate with protease and filling it into capsules. We have already confirmed from three clinical trials that PLDP enhances visual memory and delays memory recall, and we believe that its activity is due to various phospholipids, including phosphatidylcholine (PC). In this study, we clinically evaluated PLDP for depressive symptoms caused by a decline in cognitive function.

Human Milk Exosomes Induce ZO-1 Expression via Inhibition of REDD1 Expression in Human Intestinal Epithelial Cells.

Human milk exosomes (HMEs) enhance intestinal barrier function and contribute to an improvement in inflammation and mucosal injury, such as necrotizing enteritis (NEC), in infants. Here, we aimed to elucidate the intracellular factors involved in HME-induced expression of zonula occludens-1 (ZO-1), a tight junction protein, in Caco-2 human intestinal epithelial cells. HME treatment for 72 h significantly increased transepithelial electrical resistance in these cells.

Cre/LoxP Genetic Recombination Sustains Cartilage Anabolic Factor Expression in Hyaluronan Encapsulated MSCs Alleviates Intervertebral Disc Degeneration.

(1) Background: Inexplicable low back and neck pain frequently results from spinal disc degeneration with an imbalanced intervertebral disc (IVD) cell homeostasis. We hypothesize that introducing MSC expressing a sustained cartilage-anabolic factor in the IVD may stimulate the mucoid materials secreted from the IVD cells, promote the MSC's chondrogenesis and maintain the hydration content providing mechanical strength to decelerate the disc degeneration progression; (2) Methods: This study expressed a cartilage-anabolic factor runx1 by a baculoviral vector (BV) transduced MSCs through a Cre/LoxP gene editing and recombination system for sustained recombinant runx1 transcription factor production. The Cre/LoxP BV modified MSCs were encapsulated by hyaluronan hydrogel, due to its' vital composition in ECM of a healthy disc and transplanted to a punctured coccygeal disc in rats through micro-injection, followed by X-ray radiography and histological analysis at the 4- and 12-weeks post-transplantation; (3) Results: Data reveals the Cre/LoxP BV system-mediated long-termed runx1 gene expression, possessing good biosafety characteristics in the in vitro cell transduction and in vivo MSCs transplantation, and maintained superior hydration content in the disc than that of mock transduced MSCs; (4) Conclusions: This proof-of-concept study fulfills the need of implanting therapeutic cells accompanied with microinjection in the disc, such as a discography and paves a road to manufacture composite hyaluronan, such as peptide modified hyaluronan as an MSC carrier for IVD regeneration in the future study.

[Efficacy of the Extract from Fermentation of Soybean and Rice Bran on Hyperglycemia].

In recent years, lifestyle-related diseases such as hypertension and diabetes have been on the rise. These conditions can cause serious conditions such as myocardial and cerebral infarctions. Therefore, proper control of blood pressure and blood glucose levels is important issues in preventive medicine.

Runx1 Messenger RNA Delivered by Polyplex Nanomicelles Alleviate Spinal Disc Hydration Loss in a Rat Disc Degeneration Model.

Vertebral disc degenerative disease (DDD) affects millions of people worldwide and is a critical factor leading to low back and neck pain and consequent disability. Currently, no strategy has addressed curing DDD from fundamental aspects, because the pathological mechanism leading to DDD is still controversial. One possible mechanism points to the homeostatic status of extracellular matrix (ECM) anabolism, and catabolism in the disc may play a vital role in the disease's progression.

Ethnobotanical Survey on Skin Whitening Prescriptions of Traditional Chinese Medicine in Taiwan.

The increasing interest and demand for skin whitening products globally, particularly in Asia, have necessitated rapid advances in research on skin whitening products used in traditional Chinese medicine (TCM). Herein, we investigated 74 skin whitening prescriptions sold in TCM pharmacies in Taiwan. Commonly used medicinal materials were defined as those with a relative frequency of citation (RFC) > 0.

Population Pharmacokinetics of Teicoplanin and Its Dosing Recommendations for Neutropenic Patients With Augmented Renal Clearance for Hematological Malignancies.

Background: Plasma teicoplanin concentrations do not reach the therapeutic range in several patients with hematological malignancies. Nevertheless, the characteristics of the population pharmacokinetic (PPK) models have not been clarified for malignancy. The decrease in the teicoplanin concentration in patients with cancer has been attributed to augmented renal clearance (ARC).

Ethnobotanical Survey of Natural Galactagogues Prescribed in Traditional Chinese Medicine Pharmacies in Taiwan.

Natural medicinal materials have been used to promote breast milk secretion. Here, we investigated the natural medicinal materials prescribed in traditional Chinese medicine (TCM) pharmacies across Taiwan to induce lactation. We collected medicinal materials from 87 TCM pharmacies, identified them in the prescriptions, and analyzed their drug contents.

Norepinephrine transporter expressed on mammary epithelial cells incorporates norepinephrine in milk into the cells.

Mammary epithelial cells synthesize and secrete norepinephrine (NE) into breast milk to regulate β-casein expression through the adrenergic β receptor. We investigated the expression, localization, and roles of NE transporter (NET) in the mammary epithelium during lactation. mRNA and protein levels of NET were determined in primary normal human mammary epithelial cells (pHMECs) and non-malignant human mammary epithelial MCF-12A cells.

Dictamnine delivered by PLGA nanocarriers ameliorated inflammation in an oxazolone-induced dermatitis mouse model.

Dictamnine is an active pharmaceutical ingredient in Dictamnus dasycarpus, a Chinese herbal medicine widely used for the treatment of skin inflammations such as atopic dermatitis (AD). Oxazolone has been demonstrated to induce significant skin inflammation and produce inflammatory cytokine expression identical to that of AD. An in vitro HaCaT inflammation model treated with dictamnine, which efficiently scavenged the reactive oxygen species (ROS) and mitochondrial ROS (mROS), and it reduced interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α) expression, NLRP3 inflammasome activation, and NF-κB expression.

Physiologic changes in serotonin concentrations in breast milk during lactation.

Objectives: Serotonin (5-hydroxytryptamine; 5-HT) plays an important role in milk volume homeostasis in the mammary glands during lactation, and 5-HT in milk also may affect infant development. The aim of this study was to investigate changes in 5-HT concentration in breast milk according to the duration of lactation and evaluate whether the 5-HT concentration varied before and after nursing.

Methods: Healthy nursing Japanese women who had a natural delivery or underwent a cesarean delivery at Iwate Medical University Hospital were included in this study.

Engulfment of Toxic Amyloid β-protein in Neurons and Astrocytes Mediated by MEGF10.

Amyloid-β proteins (A β), including Aβ42 and A β 43, are known pathogenesis factors of Alzheimer's disease (AD). Unwanted substances in the brain, including A β, are generally removed by microglia, astrocytes, or neurons via a phagocytosis receptor. We observed that neurons and astrocytes engulfed A β 42 and A β 43, which are more neurotoxic than A β 40.

Interaction between Angiotensin Receptor and β-Adrenergic Receptor Regulates the Production of Amyloid β-Protein.

Alzheimer's disease (AD) is characterized by the formation of extracellular amyloid plaques containing the amyloid β-protein (Aβ) within the parenchyma of the brain. Aβ is considered to be the key pathogenic factor of AD. Recently, we showed that Angiotensin II type 1 receptor (ATR), which regulates blood pressure, is involved in Aβ production, and that telmisartan (Telm), which is an angiotensin II receptor blocker (ARB), increased Aβ production via ATR.

Stress-Induced Suppression of Milk Protein Is Involved in a Noradrenergic Mechanism in the Mammary Gland.

Stress decreases milk components such as milk protein and milk yield. The objective of this study was to investigate whether noradrenaline (NA) in milk constituted a factor associated with stress-induced changes in milk proteins such as β-casein. Breast milk obtained from eight healthy, nursing women contained NA at concentrations ranging from 12.

A clinical dose of angiotensin-converting enzyme (ACE) inhibitor and heterozygous ACE deletion exacerbate Alzheimer's disease pathology in mice.

Inhibition of angiotensin-converting enzyme (ACE) is a strategy used worldwide for managing hypertension. In addition to converting angiotensin I to angiotensin II, ACE also converts neurotoxic β-amyloid protein 42 (Aβ42) to Aβ40. Because of its neurotoxicity, Aβ42 is believed to play a causative role in the development of Alzheimer's disease (AD), whereas Aβ40 has neuroprotective effects against Aβ42 aggregation and also against metal-induced oxidative damage.

Iron treatment inhibits Aβ42 deposition in vivo and reduces Aβ42/Aβ40 ratio.

Alzheimer's disease (AD) is characterized by the formation of extracellular amyloid plaques containing the amyloid β-protein (Aβ) within the parenchyma of the brain. Aβ42, which is 42 amino acids in length, is considered to be the key pathogenic factor in AD. Iron deposition is found abundantly in the amyloid plaques of AD patients; however, whether iron intake exacerbates amyloid deposition in vivo is unknown.

An E3 Ubiquitin Ligase, Synoviolin, Is Involved in the Degradation of Homocysteine-Inducible Endoplasmic Reticulum Protein.

Homocysteine-inducible endoplasmic reticulum (ER) protein (Herp) is an ER stress-inducible membrane protein involved in ER-associated degradation. Herp expression is maintained at low levels through a strict regulatory mechanism, but the details of this mechanism and the reasons why Herp expression is restricted in this manner remain unclear. Here, we show that Herp degradation involves synoviolin, an ER-resident E3 ubiquitin ligase.

[Endogenous Serotonin and Milk Production Regulation in the Mammary Gland].

　Intrinsic serotonin (5-hydroxytryptamine; 5-HT) synthesized within the mammary epithelium has an important physiological role in milk volume homeostasis in many species including mice, cows, and humans. During lactation, mammary epithelial cells activate 5-HT synthesis by tryptophan hydroxylase 1 (TPH1). TPH1 catalyzes the rate-limiting step in 5-HT biosynthesis within mammary glands.

Expression of MEGF10 in cholinergic and glutamatergic neurons.

Multiple-EGF like domains 10 (MEGF10) is the mammalian homologue of Draper, a Drosophila phagocytosis receptor that plays an important role in synapse elimination and cell type-specific recognition. However, the expression and function of MEGF10 in the brain remain to be elucidated. Therefore, we aimed to clarify the regions and types of neurons that express MEGF10 in the brain, and to determine whether cells expressing MEGF10 possess phagocytic abilities.

Analysis of serotonin concentrations in human milk by high-performance liquid chromatography with fluorescence detection.

Serotonin (5-hydroxytryptamine, 5-HT) plays an important role in milk volume homeostasis in the mammary gland during lactation; 5-HT in milk may also affect infant development. However, there are few reports on 5-HT concentrations in human breast milk. To address this issue, we developed a simple method based on high-performance liquid chromatography with fluorescence detection (HPLC-FD) for measuring 5-HT concentrations in human breast milk.

NAD(P)H quinone oxidoreductase 1 inhibits the proteasomal degradation of homocysteine-induced endoplasmic reticulum protein.

Homocysteine-induced endoplasmic reticulum (ER) protein (Herp) is an ER stress-inducible key regulatory component of ER-associated degradation (ERAD) that has been implicated in insulin hypersecretion in diabetic mouse models. Herp expression is tightly regulated. Additionally, Herp is a highly labile protein and interacts with various proteins, which are characteristic features of ubiquitinated protein.

Serotonin suppresses β-casein expression via PTP1B activation in human mammary epithelial cells.

Serotonin (5-hydroxytriptamine, 5-HT) has an important role in milk volume homeostasis within the mammary gland during lactation. We have previously shown that the expression of β-casein, a differentiation marker in mammary epithelial cells, is suppressed via 5-HT-mediated inhibition of signal transduction and activator of transcription 5 (STAT5) phosphorylation in the human mammary epithelial MCF-12A cell line. In addition, the reduction of β-casein in turn was associated with 5-HT7 receptor expression in the cells.
