PROBLEM TO BE SOLVED: To obtain a composition for the oral cavity capable of preserving an aromatic ingredient in the composition before the use, emitting the aroma only at the time of use when an enzyme in the oral cavity acts and carrying out the deodorizing, masking, etc., of the halitosis. SOLUTION: This composition for the oral cavity comprises a glycoside, having a compound residue having an aroma as a constituent element and capable of producing the compound having the aroma by hydrolysis with an enzyme in the oral cavity. The saccharide residue which is the constituent element of the glycoside is preferably a residue of oligosaccharides of monosaccharides and/or di- or polysaccharides and the compound having the aroma is preferably an alcoholic aromatic compound (e.g. a monoterpene alcohol). The glycoside is obtained by enzymically or chemically carrying out the condensation reaction of saccharides with an aromatic compound or extracting the glycoside from a plant body. A usually used ingredient other than the glycoside can suitably be blended therewith to prepare a food such as a chewing gum or a candy or a quasi-drug such as a mouthwash or a dentifrice.
Malignant melanoma, the most aggressive form of skin cancer, is often incurable once metastatic dissemination of cancer cells to distant organs has occurred. We investigated the role of Transcription Factor Activating Enhancer-Binding Protein 2ε (AP2ε) in the progression of metastatic melanoma. Here, we observed that AP2ε is a potent activator of metastasis and newly revealed AP2ε to be an important player in melanoma plasticity. High levels of AP2ε lead to worsened prognosis of melanoma patients. Using a transgenic melanoma mouse model with a specific loss of AP2ε expression, we confirmed the impact of AP2ε to modulate the dynamic switch from a migratory to a proliferative phenotype. AP2ε deficient melanoma cells show a severely reduced migratory potential in vitro and reduced metastatic behavior in vivo. Consistently, we revealed increased activity of AP2ε in quiescent and migratory cells compared to heterogeneously proliferating cells in bioprinted 3D models. In conclusion, these findings disclose a yet-unknown role of AP2ε in maintaining plasticity and migration in malignant melanoma cells.
Patients with knee osteoarthritis will perform the 30 seconds chair stand test as a self test twice at home to evaluate intra rater reliability. Same patients will be tested with the same performance test by a physical therapist to evaluate the inter rater reliability.
Sepsis is one of the most significant challenges in critical care. Septic shock (SS) is the most severe form of sepsis and is associated with higher mortality, significant financial expenses and longer lengths of stay. Pathophysiological mechanisms of SS include 3 key components: 1) bacterial overgrowth, 2) spill of bacterial product into the blood causing hemodynamic insufficiency, and 3) both lead to tissue hypoxia (TH). To date the biomarkers of sepsis/SS are limited to hemodynamic parameters. However, aggressive fluid resuscitation does not fully prevent development of tissue hypoxia (TH). To date the investigators are limited in appreciating TH by measurement of lactic acid (LA), which is neither an early nor an accurate marker. Unfortunately, LA has limited predictive value in SS due to its complex metabolism. Thus, there is an acute need for biomarkers that would aid diagnosis and prognosis of sepsis/septic shock.

Cellular responses/adaptations to hypoxia rely on the transcription hypoxia-inducible factor HIF, a heterodimeric protein composed of a constitutively expressed subunit and an inducible (types 1, 2, and 3) subunit. More recently HIF was identified in diverse tissues including blood; it has been also shown that HIF expression in blood cells is representative of systemic tissues in hypoxic conditions.
BACKGROUND: Fabry nephropathy is a consequence of the deposition of globotriaosylceramide, caused by deficient GLA enzyme activity in all types of kidney cells. These deposits are perceived as damage signals leading to activation of inflammation resulting in renal fibrosis. There are few studies related to immunophenotype characterization of the renal infiltrate in kidneys in patients with Fabry disease and its relationship to mechanisms of fibrosis. This work aims to quantify TGF-β1 and active caspase 3 expression and to analyze the profile of cells in inflammatory infiltration in kidney biopsies from Fabry naïve-patients, and to investigate correlations with clinical parameters.
METHODS: Renal biopsies from 15 treatment-naïve Fabry patients were included in this study. Immunostaining was performed to analyze active caspase 3, TGF-β1, TNF-α, CD3, CD20, CD68 and CD163. Clinical data were retrospectively gathered at time of kidney biopsy.
RESULTS: Our results suggest the production of TNFα and TGFβ1 by tubular cells, in Fabry patients. Active caspase 3 staining revealed that tubular cells are in apoptosis, and apoptotic levels correlated with clinical signs of chronic kidney disease, proteinuria, and inversely with glomerular filtration rate. The cell infiltrates consisted of macrophages, T and B cells. CD163 macrophages were found in biopsy specimens and their number correlates with TGFβ1 and active caspase 3 tubular expression.
CONCLUSIONS: These results suggest that CD163+ cells could be relevant mediators of fibrosis in Fabry nephropathy, playing a role in the induction of TGFβ1 and apoptotic cell death by tubular cells. These cells may represent a new player in the pathogenic mechanisms of Fabry nephropathy.

Premature infants are at risk for a devastating infection of the intestines due to the immaturity of their intestines and immune system. Probiotics are bacteria with healthful qualities that are taken by mouth to improve the number of healthy bacteria in the intestines. Probiotics have been shown in several studies outside the U.S. to decrease the risk of serious intestinal infection and in one small study to improve the rate of weight gain in premature infants. Prebiotics are food supplements that stimulate the growth of healthy bacteria and suppress the growth of unhealthy bacteria. Prebiotics have been shown to improve the numbers of healthy bacteria in the stool of premature babies. Our study is designed to compare two over the counter probiotic/prebiotic combinations to each other and to a control group. Infants less than 35 weeks with a birthweight of 750-2000 gm are eligible and must be enrolled in the study within the first week of life. The babies are randomly assigned to either a control group (no probiotic/prebiotic, just a placebo), a group which receives Culturelle (Lactobacillus rhamnosus GG plus fructo-oligosaccharide, ConAgra), or a group which receives ProBioPlus (three strains of Bifidobacteria plus Lactobacillus acidophilus plus fructo-oligosaccharide, UAS Laboratories). The babies receive the study product by mouth twice daily for 28 days or until discharge (whichever comes first). Weekly measurements (weight, length, head size) and stool cultures are performed. Clinical progress is closely monitored and any episodes of infection are recorded.
Periprosthetic joint infections (PJI) pose a significant challenge in orthopaedic surgery, often requiring extensive surgical debridement and prolonged antibiotic treatment to eliminate the causative pathogens. Rifampin, known for its potent activity against biofilms, has been crucial in managing PJI by penetrating and disrupting these formations, thereby improving treatment efficacy. In this sense, antibiotic protocols lacking rifampin have shown increased failure rates. Consequently, the development of rifampin resistance could severely influence the prognosis of PJI. The aim of this clinical study was to assess how rifampin resistance affects the functional outcome in patients with PJI. In this single-centre comparative cohort study, we systematically documented all patients who presented with a PJI during the period spanning from 2018 to 2020. Two distinct groups were established for the study: Group 1 comprised 35 patients with a PJI caused by rifampin-susceptible pathogens and group 2 consisted of 28 patients with PJI caused by rifampin-resistant pathogens. A total of 63 patients (34 females) with a mean age of 68 years and a mean follow up of 37 months were included. The examination of patient-specific parameters did not reveal any identified risk factors as influential. Patients with a rifampin-resistant pathogen underwent a greater number of surgical revisions (6.9 ± 5.1 compared to 3.59 ± 3.39, p = 0.0011) and had extended durations of antibiotic treatment (p = 0.0052). The results of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score revealed significant differences in clinical outcome between both groups in every domain, even when stratified by acute and chronic entities. In total the WOMAC increased significantly from 21.57 ± 14.9 points in group 1 to 71.47 ± 62.7 points in group 2 (p < 0.001). The higher failure rates observed in group 2 were not statistically significant (p = 0.44). The current study demonstrates that PJI caused by rifampin-resistant bacteria are associated with a significantly worse functional outcome in both acute and chronic infection types without significantly affecting total failure rates.
PURPOSE:To provide the title composition containing an oil-soluble vitamin included in a hydrogenated phospholipid matrix in a state to have high stability and transcutaneous absorbability, by dissolving an oil-soluble vitamin in an organic solvent solution of a hydrogenated phospholipid, and drying and pulverizing the solution. CONSTITUTION:The titled composition composed of an oil-soluble vitamin included in a hydrogenated phospholipid matrix is produced by dissolving or dispersing an oil-soluble vitamin (e.g. vitamin/A,D,E, fatty acid ester of vitamin C, etc.) in an organic solvent (e.g. hexane, heptane, etc.) solution of a hydrogenated phospholipid, and drying and pulverizing the solution or dispersion. The hydrogenated phospholipid is produced by hydrogenating a phospholipid originated from yolk, soybean, etc., and preferably has an iodine value of 0-60. Since the oil-soluble vitamin is included in the matrix structure of the phospholipid, the stability and the transcutaneous of the phospholipid, the stability and the transcutaneous absorbability of the vitamin can be improved.
BACKGROUND: Venous thromboembolism is a sudden cardiovascular disease that can lead to death, and its pathologic development is closely related to vascular viscosity and inflammation. However, direct evidence from in vivo is really scarce. The key limitation is that the combined probes cannot detect multiple markers simultaneously, which may lead to unreliable results. Therefore, to develop a single probe that can simultaneously monitor the variations of viscosity in the vascular microenvironment as well as inflammation level during venous thrombosis.
RESULTS: A dual-responsive two-photon fluorescent probe, Cou-ONOO, was designed and synthesized. Cou-ONOO provides a visualization tool for monitoring the viscosity of the vascular as well as the inflammatory marker ONOO‾ during thromboembolism via dual-channel simultaneous imaging. As a single probe that can recognize dual targets, Cou-ONOO effectively avoids the problems from unreliable results caused by complex synthesis and differences in intracellular localization, diffusion, and metabolism of different dyes as using combinatorial probes. Using Cou-ONOO, simultaneous imaging the variations of viscosity and ONOO‾at the cellular and tissue levels was successfully performed. In addition, Cou-ONOO also successfully visualized and tracked the viscosity of the vascular microenvironment and ONOO‾ during venous embolism in mice.
SIGNIFICANCE: Experimental results show that both viscosity and inflammation are abnormally overexpressed in the microenvironment at the thrombus site during venous thrombosis. An intuitive visualization tool to elucidate the variations of viscosity as well as inflammation level in the vascular microenvironment during thrombosis was provided, which will facilitate a better clinical understanding of the pathological process of thrombosis.
Women between the ages of 30 and 60 years of age who work in positions that require them to be seated at desks for a large portion of each day, are capable of following the protocol for one year, have a t-score \>- 2.5 (do not have osteoporosis), and respond to plantar stimulation will be asked to participate. Women will be excluded who are receiving medications for osteoporosis, taking hormone replacement therapy, taking steroids (either oral or inhaled), have metal implants in the tibia, hip and spine that interfere with DEXA (bone density) scanning, are professional or semi-professional athletes, have hyperparathyroidism, have a history of pulmonary embolism, deep vein thrombosis, peripheral vascular disease or varicose veins, have a Body Mass Index greater than 40 Kg/m2, have any type of neuromuscular disease, or are pregnant . Once the inclusion and exclusion criteria are met, 45 subjects will be randomized into 3 groups including 1) a group of 15 subjects who will use the device (stimulation) for up to 4 hours a day, 2) a group of 15 subjects that will use the device for up to 8 hours a day, and 3) a control group who will not use the device. Subjects in the two treatment groups will be asked to place their feet on a mechanical device that will deliver a slight vibration while they are seated at work. Vibrations between 30-60 Hz has been shown to stimulate the Meissner's corpuscles which in turn stimulate contraction of the deep muscles of the calves. This contraction has been shown to increase venous and lymphatic return from the lower extremities thus improve bone metabolism. Bone density readings and venous circulation will be measured at the onset of this research and will be repeated after 12 months of using the device.
Motopsin, a serine protease encoded by PRSS12, is secreted by neuronal cells into the synaptic clefts in an activity-dependent manner, where it induces synaptogenesis by modulating Na+/K+-ATPase activity. In humans, motopsin deficiency leads to severe intellectual disability and, in mice, it disturbs spatial memory and social behavior. In this study, we investigated mice that overexpressed motopsin in the forebrain using the Tet-Off system (DTG-OE mice). The elevated agrin cleavage or the reduced Na+/K+-ATPase activity was not detected. However, motopsin overexpression led to a reduction in spine density in hippocampal CA1 basal dendrites. While motopsin overexpression decreased the ratio of mature mushroom spines in the DG, it increased the ratio of immature thin spines in CA1 apical dendrites. Female DTG-OE mice showed elevated locomotor activity in their home cages. DTG-OE mice showed aberrant behaviors, such as delayed latency to the target hole in the Barnes maze test and prolonged duration of sniffing objects in the novel object recognition test (NOR), although they retained memory comparable to that of TRE-motopsin littermates, which normally express motopsin. After NOR, c-Fos-positive cells increased in the dentate gyrus (DG) of DTG-OE mice compared with that of DTG-SO littermates, in which motopsin overexpression was suppressed by the administration of doxycycline, and TRE-motopsin littermates. Notably, the numbers of doublecortin- and 5-bromo-2'-deoxyuridine-labeled cells significantly increased in the DG of DTG-OE mice, suggesting increased adult neurogenesis. Importantly, our results revealed a new function in addition to modulating neuronal responsiveness and spine morphology in the DG: the regulation of neurogenesis.
The present invention concerns fusion of Fc domains with biologically active peptides and a process for preparing pharmaceutical agents using biologically active peptides.

BACKGROUND: No previous studies have examined the association between attitudes and beliefs of chiropractors and their adherence to low back pain (LBP) guidelines. The aim of this study is: (1) to assess the attitudes and beliefs towards the management of LBP of Dutch and Belgian chiropractors; and (2) to investigate the association of these attitudes and beliefs on the use of diagnostic imaging and on the adherence to diagnostic guidelines and guidelines in the management of patients with LBP.
METHODS: STUDY DESIGN: Cross-sectional study using a web-based questionnaire in chiropractic private practices in the Netherlands and Belgium. The survey included sociodemographic characteristics, use of diagnostic imaging, the Pain Attitude and Beliefs Scale-Physiotherapists (PABS.PT) and 6 vignettes (3 acute and 3 chronic LBP patients). We used Latent Profile Analysis (LPA) to categorise the chiropractors into clusters depending on their PABS.PT outcome, whereby the classes differed primarily on the biomedical score. We used linear, logistic, and mixed models to examine the associations between these clusters, and adherence to the recommendations of guidelines on: (1) diagnostic imaging use, and (2) management of LBP (i.e. advice on activity, treatment, return-to-work, and bedrest).
RESULTS: The response rate of the Dutch and Belgian chiropractors was 61% (n = 149/245) and 57% (n = 54/95), respectively. The majority of chiropractors scored midrange of the biomedical scale of the PABS.PT. Three clusters were identified using LPA: (1) high biomedical class (n = 18), (2) mid biomedical class (n = 117) and (3) low biomedical class (n = 23). Results from the vignettes suggest that chiropractors in the high biomedical class better adhere to diagnostic imaging guidelines and to LBP guidelines when it concerns advice on return-to-work and activity compared to the other two classes. However, no differences were identified between the classes for treatment of LBP. All chiropractors adhered to the guidelines' recommendation on bedrest.
CONCLUSION: The high biomedical class demonstrated better overall adherence to the practice guidelines for the management of LBP and diagnostic imaging than the other classes. Due to the small numbers for the high and low biomedical classes, these results should be interpreted with caution.
There is no study that has investigated the impact of exercise in a combined hypoxic and hot environment on endothelial function. Therefore, we tested whether aerobic exercise in a combined hypoxic and hot conditions induces further enhancement of endothelial function. Twelve healthy males cycled at a constant workload (50% of their maximal oxygen uptake under normoxic/thermoneutral conditions) for 30 min in four different environments: exercise under normoxic condition (NOR: fraction of inspiratory oxygen or FiO2 = 20.9%, 20°C), exercise under hypoxic condition (HYP: FiO2 = 14.5%, 20°C), exercise under hot condition (HOT: FiO2 = 20.9%, 30°C), and exercise under combined hypoxia and hot conditions (HH: FiO2 = 14.5%, 30°C). Before, during, and after exercise, cardiovascular variables (e.g., heart rate, blood flow, and shear rate), blood variables, and endothelial function evaluated by flow-mediated dilation (FMD) were assessed. Heart rates were significantly higher throughout the HH trial's experimental period than the other trials (p < 0.05). However, in the HH trial, brachial artery blood flow and shear rate did not differ from those in other trials after exercise. Plasma catecholamines (epinephrine, norepinephrine, and dopamine) elevations in response to exercise were significantly higher in the HH trial than in the other three trials (p < 0.05). No considerable differences were observed in FMD responses among trials before and after the exercise. In conclusion, aerobic exercise in a combined hot and hypoxic environment further activated sympathetic nervous activity but did not considerably enhance blood flow, shear rate, or endothelial function.

The quantity and quality of the adipose tissue is altered in obesity: hypertrophy of adipocytes, decrease in expandability, fibrosis, production of pro-inflammatory cytokines and adipokines, inflammatory infiltration by pro-inflammatory M1 macrophages and T lymphocytes. Excess adipose tissue and obesity are associated with low-grade inflammation that can aggravate chronic inflammatory diseases, decrease treatment efficacy, contribute to the development of comorbidities, and of the disease in its preclinical phase. Obesity increases the incidence of rheumatoid arthritis (RA), psoriasis, psoriatic arthritis with a weight-dose effect. It is also a predictor of worse response to treatment, in particular TNF inhibitors. Weight loss induced by bariatric surgery decreases the risk of psoriasis and psoriatic arthritis and improves disease activity and remission in RA. A 5% weight loss through a low-calorie diet improves the response to TNF inhibitors in psoriatic arthritis, losing even more weight improves the response even more. In RA, the beneficial effect of weight loss from a low-calorie diet on disease activity has been reported in a few observational studies but has not been demonstrated in a randomized controlled trial. Screening and management of obesity are part of the dietary recommendations of the French Society for Rheumatology in patients with chronic inflammatory rheumatic diseases. Of course, this should be combined with other lifestyle modifications such as smoking cessation, higher food quality, increased physical activity and reduced sedentary behavior.
