PURPOSE: To obtain a composition for oral administration for lowering blood cholesterol level, containing psyllium seed gum and non-absorbing non-digestive polyol polyester. CONSTITUTION: This composition contains (A) psyllium seed gum or psyllium seed gum source (e.g. immersed and softened seed coat of psyllium seed) and (B) a non-absorbing non-digestive polyol polyester which is an esterfied polyol having at least four fatty acid ester groups and <=2 unesterfied hydroxyl groups (e.g. octaoleic acid scrose, octalinolic acid scrose or octaparmitic acid scrose). The effect is further enhanced by compounding a fat-soluble vitamin. The dose of the component A is 1-30g and the dose of the component B is 5-50g. In long- term ingestion, the daily dose of the component A is 5-15g and the component B is 15-50g.
Tolvaptan is a selective vasopressin V2-receptor antagonist with an affinity for the V2-receptor that is 1.8 times that of native arginine vasopressin (AVP). Tolvaptan affinity for the V2-receptor is 29 times that for the V1a-receptor. Decreased binding of vasopressin to the V2-receptor in the kidney lowers adenylate cyclase activity resulting in a decrease in intracellular adenosine 3′, 5′-cyclic monophosphate (cAMP) concentrations. Decreased cAMP concentrations prevent aquaporin 2 containing vesicles from fusing with the plasma membrane, which in turn causes an increase in urine water excretion, an increase in free water clearance (aquaresis) and a decrease in urine osmolality. In human ADPKD cyst epithelial cells, tolvaptan inhibited AVP-stimulated in vitro cyst growth and chloride-dependent fluid secretion into cysts. In animal models, decreased cAMP concentrations were associated with decreases in the rate of growth of total kidney volume and the rate of formation and enlargement of kidney cysts. Tolvaptan metabolites have no or weak antagonist activity for human V2-receptors compared with tolvaptan.
PURPOSE: To explore whether circadian clock genes contribute to elicit inflammation in experimental dry eye (EDE).
METHODS: RNA sequencing analyzed mRNA expression patterns in EDE model. RT-qPCR and/or Western blot determined the expression of inflammatory factors and circadian genes during EDE. MethylTarget™ assays determined the promoter methylation levels of Per genes in vivo. Per2 or Per3 knockdown assessed their effects on inflammatory factors in vitro.
RESULTS: We utilized an intelligently controlled environmental system (ICES) to establish a mouse EDE model. The significant upregulated genes were enriched for circadian rhythms. Therein lied oscillatory and time-dependent upregulation of PER2 and PER3, as well as their promoter hypomethylation during EDE. Silencing PER2 or PER3 significantly decreased inflammatory factor expression and also reversed such increased inflammatory response in azacitidine (AZA) treatment in vitro model.
CONCLUSIONS: Our findings suggest that DNA methylation mediated the upregulation of PER2 and PER3, leading to inflammatory response in EDE.
Infantile hemangiomas (IH) are among the most common, benign vascular tumors of infancy with an estimated prevalence of 4-5% of the population. IH are not found at birth but become evident within the first few weeks of life. They are characterized by a rapid proliferative phase that can last up to 4-6 months or longer and then a period of minimal or absent growth before an involutive phase where they may resolve with minimal or no scarring over multiple years. Although frequently thought of as benign lesions, hemangiomas can occur in locations to cause functional impairment of vital organs, can lead to ulcerations, scarring or disfigurement, and can lead to life-threatening complications. Management of these problematic IH includes laser, long-term systemic corticosteroids, interferon, Vincristine, surgery, and most recently systemic propranolol. Pulsed-dye laser is the only treatment approved by the FDA; it has been useful for superficial hemangiomas but has little effect on subcutaneous or deep-seated hemangiomas. The proposed therapeutic effects of propranolol are vasoconstriction, decreased expression of vascular endothelial growth factor (VEGR) and basic fibroblast growth factors (bFGF) genes through downregulation of Raf/mitogen-activated protein kinase pathway, and apoptosis of capillary endothelial cells. For periorbital lesions that may cause amblyopia or anisometropia, topical Timolol has been reported to be of benefit. There is one retrospective review that is proof of concept that shows that topical timolol is safe and effective treatment for 6 cases of IH.

The advantage of a topical therapy is the decreased risk of systemic side effects compared with oral or intravenous administration. The disadvantage is that limited penetration may preclude effectiveness for the thicker or deeper lesions.

Being of low birth weight as well as prematurity are known risk factors for IH. In the premature infant development clinic at the University of Texas Health Science Center in San Antonio infants less than 1500 grams birth weight are followed for three years following discharge from the Newborn Intensive Care Unit (NICU); approximately 16% of these infants have hemangiomas. Therefore the investigators find it reasonable to start treatment with a topical beta blocker at an early stage of hemangioma to prevent the growth and proliferation and hence the possible severe effects associated with growth and thus impairment of vital organs/tissues.
Patients with stage IA inoperable peripheral lung tumor will be performed ablation. cfDNA methylation would be monitored at different times(before surgery , after surgery 1month, 3month, and every 3month in the first year and every 6 months in the second ). Meanwhile, post-treatment response will be evaluated and follow up will be carried out according to the standard procedure.

We will invite approximately 50 adult patients with PKU who were or are still being managed in the PPB clinic of the Pediatric Clinic of the University Medical Center Ljubljana. It is estimated that half of the patients still fully or at least partially follow the dietary treatment.
OBJECTIVES: Despite the difficulty in distinguishing between squamous cell carcinoma (SCC) and medication-related osteonecrosis of the jaw (MRONJ) on the basis of medical imaging examinations, the two conditions have completely different treatment methods and prognoses. Therefore, differentiation of SCC from MRONJ on imaging examinations is very important. This study aimed to distinguish SCC from MRONJ by performing texture analysis using magnetic resonance imaging (MRI) short-tau inversion recovery images.
METHODS: This retrospective case-control study included 14 patients with SCC of the lower gingiva and 35 with MRONJ of the mandible who underwent MRI and computed tomography (CT) for suspected SCC or MRONJ. SCC was identified by histopathological examination of tissues excised during surgery. The radiomics features of SCC and MRONJ were analyzed using the open-access software MaZda version 3.3 (Technical University of Lodz, Institute of Electronics, Poland). CT was used to evaluate the presence or absence of qualitative findings (sclerosis, sequestrum, osteolysis, periosteal reaction, and cellulitis) of SCC and MRONJ.
RESULTS: Among the 19 texture features selected using MaZda feature-reduction methods, SCC of the gingiva and MRONJ of the mandible revealed differences in two histogram features, one absolute gradient feature, and 16 Gy level co-occurrence matrix features. In particular, the percentile, angular second moment, entropy, and difference entropy exhibited excellent diagnostic performance.
CONCLUSION: Non-contrast-enhanced MRI texture analysis revealed differences in texture parameters between mandibular SCC and mandibular MRONJ. MRI texture analysis can be a new noninvasive quantitative method for distinguishing between SCC and MRONJ.
PURPOSE: To assess the long-term cosmetic outcomes of the "slit-slide procedure", designed to provide a more natural appearance for umbilical hernia repair, as perceived by the patients and their parents.
METHODS: A total of 149 patients with umbilical hernia underwent the slit-slide procedure at our hospital. The slit-slide procedure allows for the creation of an umbilicus with a more natural and integrated appearance. The patient satisfaction survey questionnaire was mailed to the families (n = 139), and there were 74 (53.2%) respondents. A questionnaire survey on postoperative appearance was also distributed to pediatric surgeons.
RESULTS: The median age at the time of operation was 2.5 years (range, 2 months to 14 years) and the average median age at the time of answering the questionnaire was 6.25 years old (range, 2.5-14.8 years). The average median period of observation was 3.2 years (range, 4 months to 8.97 years). Most patients (89.2%) and parents (93.2%) were satisfied with the appearance of the umbilicus. Twenty-seven patients reported improved satisfaction after surgery (36.2%). Surgeons tended to score the elongated-oval shape highly; however, there was no difference in satisfaction among the shapes.
CONCLUSION: The slit-slide procedure is not only effective and safe, but it achieves a satisfactory aesthetic outcome.
Unilateral nociceptive stimulation is associated with subtle signs of pupil asymmetry that may reflect lateralized activity in the locus coeruleus. To explore drivers of this pupil asymmetry, electrical stimuli, delivered alone or 200 ms before or after an acoustic startle stimulus, were administered to one ankle under four experimental conditions: with or without a 1.6 s anticipatory period, or while the forearm ipsilateral or contralateral to the electrical stimulus was heated tonically to induce moderate pain (15 healthy participants in each condition). Pupil diameter was measured at the start of each trial, at stimulus delivery, and each second for 5 s after stimulus delivery. At the start of the first trial, the pupil ipsilateral to the side on which electric shocks were later delivered was larger than the contralateral pupil. Both pupils dilated robustly during the anticipatory period and dilated further during single- and dual-stimulus trials. However, pupil asymmetry persisted throughout the experiment. Tonically-applied forearm heat-pain modulated the pupillary response to phasic electrical stimuli, with a slight trend for dilatation to be greater contralateral to the forearm being heated. Together, these findings suggest that focusing anxiously on the expected site of noxious stimulation was associated with dilatation of the ipsilateral pupil whereas phasic nociceptive stimuli and psychological arousal triggered bilateral pupillary dilatation. It was concluded that preparatory cognitive activity rather than phasic afferent nociceptive input is associated with pupillary signs of lateralized activity in the locus coeruleus.
Temporomandibular joint inflammatory diseases are a significant subtype of temporomandibular disorders (TMD) characterized by inflammatory pain in the orofacial area. The N-methyl-D-aspartate receptor (NMDAR), specifically the NR2A subtype, was crucial in neuropathic pain. However, the exact role of NR2A in inflammatory pain in the TMJ and the molecular and cellular mechanisms mediating peripheral sensitization in the trigeminal ganglion (TG) remain unclear. This study utilized male and female mice to induce the TMJOA model by injecting Complete Freund's adjuvant (CFA) into the TMJ and achieve conditional knockout (CKO) of NR2A in the TG using Cre/Loxp technology. The Von-Frey filament test results showed that CFA-induced orofacial pain with reduced mechanical withdrawal threshold (MWT), which was not developed in NR2A CKO mice. Additionally, the up-regulation of interleukin (IL)-1β, IL-6, and nerve growth factor (NGF) in the TG induced by CFA did not occur by NR2A deficiency. In vitro, NMDA activated satellite glial cells (SGCs) with high expression of glial fibrillary acidic protein (GFAP), and both NMDA and LPS led to increased IL-1β, IL-6, and NGF in SGCs. NR2A deficiency reduced these stimulating effects of NMDA and LPS. The regulation of IL-1β involved the p38, Protein Kinase A (PKA), and Protein Kinase C (PKC) pathways, while IL-6 signaling relied on PKA and PKC pathways. NGF regulation was primarily through the p38 pathway. This study highlighted NR2A's crucial role in the TG peripheral sensitization during TMJ inflammation by mediating ILs and NGF, suggesting potential targets for orofacial inflammatory pain management.
BACKGROUND: Being overweight or obese has become a serious public health concern, and accurate assessment of body composition is particularly important. More precise indicators of body fat composition include visceral adipose tissue (VAT) mass and total body fat percentage (TBF%). Study objectives included examining the relationships between abdominal fat mass, measured by quantitative computed tomography (QCT), and the whole-body and regional fat masses, measured by dual energy X-ray absorptiometry (DXA), as well as to derive equations for the prediction of TBF% using data obtained from multiple QCT slices.
METHODS: Whole-body and regional fat percentage were quantified using DXA in Chinese males (n = 68) and females (n = 71) between the ages of 24 and 88. All the participants also underwent abdominal QCT measurement, and their VAT mass and visceral fat volume (VFV) were assessed using QCT and DXA, respectively.
RESULTS: DXA-derived TBF% closely correlated with QCT abdominal fat percentage (r = 0.89-0.93 in men and 0.76-0.88 in women). Stepwise regression showed that single-slice QCT data were the best predictors of DXA-derived TBF%, DXA android fat percentage and DXA gynoid fat percentage. Cross-validation analysis showed that TBF% and android fat percentage could be accurately predicted using QCT data in both sexes. There were close correlations between QCT-derived and DXA-derived VFV (r = 0.97 in men and 0.93 in women).
CONCLUSION: Clinicians can assess the TBF% and android and gynoid fat percentages of Chinese women and men by analysing existing abdominal CT-derived data using the QCT technique.
A method of producing an influenza virus and vaccines derived from the virus utilizes cultured vertebrate biomass aggregates comprising a plurality of cell types derived from a plurality of vertebrate tissues and is particularly suitable for use with chicken embryo cultures. The method both eliminates the necessity to use costly methods requiring whole chicken embryos and provides proteases suitable for the activation of a wide variety of viruses. After infecting the cells of the culture with an influenza virus, which is preferably modified to create a cleavage site in the hemagglutinin of the virus, a substance such as a protease is introduced that cleaves the hemagglutinin. The culture then is incubated under conditions that permit growth of the virus. The method provides also for the augmentation of virus activation in the culture by the continuous or batchwise removal of culture media, treatment of the media with substances such as proteases which increase cellular activation, attenuation of any undesired effects of the augmentation and return of the augmented media to the culture. The vaccines produced from the harvested virus therefore are free of egg proteins and are much more economical to produce. The methodology of the present invention allows the large scale continuous production of many viruses to a high titre.
BACKGROUND & AIMS: Obesity is associated with vitamin D (VitD) deficiency. However, previous studies showed mixed effects of VitD (25-hydroxyVitD/calcidiol) supplementation on body weight. The biological actions of VitD require the hydroxylation of inactive VitD into active VitD (1.25-dihydroxyVitD/calcitriol). This step is highly regulated; therefore, supplementing with inactive VitD might not be sufficient to overcome the potential adverse health effects of VitD deficiency. The objective of this study was to conduct a systematic review and individual participant data (IPD) meta-analysis of data acquired from randomised placebo-controlled calcitriol trials (RCTs) to determine the effects of calcitriol on body weight and weight-related parameters.
METHODS: Studies were identified from MEDLINE, EMBASE, and CENTRAL databases up to January 27, 2024, and excluded those involving dialysis or cancer patients. We obtained IPD from eligible trials and assessed bias using the Cochrane Collaboration risk-of-bias tool and methodological quality using the Heyland Methodological Quality Score. The study was prospectively registered with PROSPERO (CRD42017076202).
RESULTS: Although none of the studies reported information regarding our primary objective, we obtained IPD for 411 patients, with 206 randomised to receive calcitriol and 205 to placebo. This dataset enabled us to conduct an IPD meta-analysis with 17,084 person-months of follow-up (median: 11 months). Meta-analysis showed that calcitriol does not alter body weight, BMI, waist circumference, fat mass or lean body mass compared to placebo. Adjusting for age and sex did not alter the outcomes.
CONCLUSIONS: In conclusion, this systematic review and IPD meta-analysis indicate that calcitriol does not affect body weight in normal-weight postmenopausal women and lean patients with type 1 diabetes nor in people suffering from obesity, type 2 diabetes and chronic kidney disease. Whether calcitriol lowers body weight in VitD-sufficient people with obesity remains to be elucidated.
The invention relates to a radio frequency identification device (RFID) system powered by a lithium ion battery and used for storing individual tuberculosis information and belongs to the technical field of application of internet of things. Chest X-ray examination and a chest computed tomography (CT) examination are conducted on an individual in an iconographical examination room. A result showing whether a tuberculosis focus exits is transmitted out through a first wireless transmission antenna, and a result of checking tubercle bacillus in sputum under a microscope for checking the tubercle bacillus is transmitted out through a second wireless transmission antenna. A built-in antenna in an electronic label receives the information transmitted by the first wireless transmission antenna and the second wireless transmission antenna and inputs the information into an integrated circuit (IC) chip to be stored. An RFID reader-writer powered by the lithium ion battery through a conductor wire forms an electromagnetic field on the periphery through the antennas. The electronic label is triggered in the electromagnetic field, after the RFID reader-writer obtains tubercle bacillus check result information in the electronic label, the information is input into a computer for managing tuberculosis treatment through a data line to be analyzed, processed and stored, and the information is input into a printer through a data line to print a paper tubercle bacillus check report.
Protein aggregation plays a crucial role in the development of several neurodegenerative diseases. It is important to understand the aggregation process for the detection of the onset of these diseases. Alzheimer's Disease (AD) is one of the most prevalent neurodegenerative diseases caused by the aggregation of Aβ-40 and Aβ-42 peptides. The smaller oligomers lead to the formation of protein plaque at the neural membranes leading to memory loss and other disorders. Interestingly, aggregation takes place at the neural membranes, therefore the membrane composition seems to play an important role in the aggregation process. Despite a large number of literatures on the effect of lipid composition on protein aggregation, there are very few concise reviews that highlight the role of membrane composition in protein aggregation. In this review, we have discussed the implication of membrane composition on the aggregation of amyloid beta peptide with a special emphasis on cholesterol. We have further discussed the role of the degree of unsaturation of fatty acids and the participation of apolipoprotein E4 (ApoE4) in the onset of AD.
A 6-month-old female infant with megalophthalmos was referred with the suspicion of congenital glaucoma. Refractive measurements obtained with handheld autorefractometry were -7.00 -2.00 × 90° in the right eye and -6.00 -2.00 × 100° in the left eye and ultrasonic axial lengths were 22.50 mm in both eyes. Intraocular pressures and vertical and horizontal corneal diameters of the proband were 11 mm Hg, 11 mm, and 11.50 mm in both eyes, respectively. She was diagnosed as having early-onset high myopia. Her father also had degenerative high myopia (-12.00 diopters) in the right eye, bilateral congenital lens opacities, and retinal detachment in the left eye. Her mother was emmetropic with normal eye examination results. Clinical exome sequencing analysis revealed a novel ENST00000380518.3 c.3528_3530 delins GACCATTAGCA (Chr12:48369813: GCA > TGCTAATGGTC) variant in the collagen type II alpha 1 chain (COL2A1) on chromosome 12q13 (OMIM 108300), consistent with the Stickler syndrome type 1. Subsequent segregation analysis revealed paternal inheritance. Although many pathogenic null variants have been described within the COL2A1 gene, there is currently no documented literature pertaining to this specific variant, making this the inaugural report of its manifestation in scientific discourse.
