BACKGROUND: The overgrowth of Desulfovibrio, an inflammation promoting flagellated bacteria, has been found in ulcerative colitis (UC) patients. However, the molecular mechanism in promoting colitis remains unestablished.
METHODS: The relative abundance Desulfovibrio vulgaris (D. vulgaris) in stool samples of UC patients was detected. Mice were treated with dextran sulfate sodium to induce colitis with or without administration of D. vulgaris or D. vulgaris flagellin (DVF), and the severity of colitis and the leucine-rich repeat containing 19 (LRRC19) signaling were assessed. The interaction between DVF and LRRC19 was identified by surface plasmon resonance and intestinal organoid culture. Lrrc19-/- and Tlr5-/- mice were used to investigate the indispensable role of LRRC19. Finally, the blockade of DVF-LRRC19 interaction was selected through virtual screening and the efficacy in colitis was assessed.
RESULTS: D. vulgaris was enriched in fecal samples of UC patients and was correlated with the disease severity. D. vulgaris or DVF treatment significantly exacerbated colitis in germ-free mice and conventional mice. Mechanistically, DVF could interact with LRRC19 (rather than TLR5) in colitis mice and organoids, and then induce the production of pro-inflammatory cytokines. Lrrc19 knockdown blunted the severity of colitis. Furthermore, typhaneoside, a blockade of binding interfaces, blocked DVF-LRRC19 interaction and dramatically ameliorated DVF-induced colitis.
CONCLUSIONS: D. vulgaris could promote colitis through DVF-LRRC19 interaction. Targeting DVF-LRRC19 interaction might be a new therapeutic strategy for UC therapy. Video Abstract.
Women assigned to prophylactic NPWT will have the Prevena device applied and secured with fixation adhesion strips. The device will be monitored while the patient is in the hospital to confirm that it is functioning well. The device will be removed prior to discharge, typically on postoperative day 4, but longer for up to 7 days for patients who remain hospitalized.
Participants in this group will start the intervention 10 weeks after the randomization. Participants in the waiting list control group will be randomly distributed by the fixed standardised and self-tailored arms. This arm will follow the exact same procedure of the active arms.
1,210,938. Radio-active materials. UNION CARBIDE CORP. 31 Jan., 1968, No. 5006/68. Heading G6R. A saline solution containing a constant concentration of a radio-active gas, for use in radiopharmaceutical diagnosis, is prepared by condensing a radio-active gas into an evacuated zone containing sodium chloride, entirely filling the zone with water to form an isotonic solution, displacing the solution by means of an insoluble silicone oil, and dispensing the solution into sealable cartridges. The gas may be Xe-133 or Kr-85. In a modification, the radio-active gas is condensed in the dissolution zone in the absence of sodium chloride, and saline solution is admitted subsequently instead of water. A method is described of transferring the solution from a cartridge into a hypodermic syringe.
Patients receive lutetium texaphyrin IV over 10-15 minutes 3-24 hours before photodynamic therapy (PDT). Optical fibers attached to a laser are inserted through a catheter into the prostate. The laser delivers 730 nm light to the prostate until the specified fluence is delivered. Patients undergo biopsy of the prostate and bladder before and after PDT. Cohorts of 3-6 patients receive escalating doses of lutetium texaphyrin and light fluence until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose limiting toxicity.
This study requires two visits. Once determined eligible by the study criteria, during the first visit the participant will be randomly placed to receive one of two high-fat meals. The participant will receive the other study meal during the second visit. At each visit, brachial artery ultrasounds will be performed before and 3 hours after the meal is eaten. The sample size is 50 subjects. This study will be conducted at the Clinical Research Center at Tufts Medical Center.
General anesthesia is thought to suppress the immune system and negatively affect postoperative infection and the long-term prognosis of cancer. However, the mechanism underlying immunosuppression induced by general anesthetics remains unclear. In this study, we focused on propofol, which is widely used for sedation under general anesthesia and intensive care and examined its effects on the T cell function and T cell-dependent immune responses. We found that propofol suppressed T cell glycolytic metabolism, differentiation into effector T cells, and cytokine production by effector T cells. CD8 T cells activated and differentiated into effector cells in the presence of propofol in vitro showed reduced antitumor activity. Furthermore, propofol treatment suppressed the increase in the number of antigen-specific CD8 T cells during Listeria infection. In contrast, the administration of propofol improved inflammatory conditions in mouse models of inflammatory diseases, such as OVA-induced allergic airway inflammation, hapten-induced contact dermatitis, and experimental allergic encephalomyelitis. These results suggest that propofol may reduce tumor and infectious immunity by suppressing the T cell function and T cell-dependent immune responses while improving the pathogenesis and prognosis of chronic inflammatory diseases by suppressing inflammation.
1439398 Flavanone derivative H TROM. MSDORFF 28 Nov 1973 [8 Dec 1972] 55278/73 Heading C2C A novel flavanone derivative obtainable from succus liquiritrae, having the empirical formula the presumed structural formula (in which the 3-position side change is that of a dimeric methylated hexuronic acid) exhibiting an Rf value of 0.79 in a thin-layer chromatogram on silica gel in a 2 : 1.5 water (saturated with chloroform)-glacial acetic acid system, is obtained from an aqueous dispersion prepared from a mixture extracted from roots of glycyrrhiza glabra by treating with a solvent thereby dissolving the undesired red dyestuff, adjusting the pH of the reaction mixture to a moderately acidic value by addition of water or dilute acid thus precipitating a glycyrrhizinic acid contaminated with yellow dyestuff, separating and discarding the supernatant solution containing the red dyestuff, dissolving the precipitate in dilute alcoholic acid and subjecting to an alcoholysis with simultaneous methylation, discarding the precipitated glycyrrhetinic acid and obtaining the flavanone by boiling down and drying the remaining solution. The starting material may be an extract from succus liquiritrae. Alternatively, instead of the aqueous dispersion, there may be used as starting material a commercial dyestuff-containing ammoniacal glycyrrhizine dissolved in concentrated nitric acid. The solvent used to dissolve the red dyestuff is preferably ethyl urethane. Pharmaceutical compositions, suitable for treating various diseases of the gastric and intestinal tract, wound cicatrization and for treatment of inflammation, comprise a flavanone as described above, together with one or more conventional solid or liquid adjuvants or carriers, in forms suitable for administration orally, topically or intramuscularly.

OBJECTIVES: To summarize the clinical characteristics and prognosis of children with nasolabial fold rhabdomyosarcoma (RMS).
METHODS: Retrospective review of children treated for nasolabial fold RMS from January 2014 to September 2019.
RESULTS: Of 21 patients with nasolabial fold RMS, 90.48% were alveolar subtype, in which PAX3/7-FOXO1 fusion positive accounted for 87.5%. Ten patients (47.62%) had nodals invasion. Almost all patients received comprehensive treatment (chemotherapy [100%], radiation therapy [100%], and surgery [95.24%]). The median follow-up time was 34.3 months. The 3-year overall survival (OS) and event-free survival (EFS) was 67.7% ± 14.1% and 42.1% ± 13.5%, respectively. Four patients had regional lymph node relapse (NR), all in the ipsilateral submandibular lymph node region.
CONCLUSION: Majority of the patients with RMS in the nasolabial fold area were alveolar subtype and had positive PAX3/7-FOXO1 gene fusion. In addition, the nasolabial fold RMS had a high probability of regional lymph node metastasis in the submandibular area. To maintain the facial aesthetics and functions, the surgical area for nasolabial fold RMS is often very conservative and restricted. This could be one of the contributors for the poor prognosis of nasolabial fold RMS beside its worse pathological subtype and gene fusion.
Phospholipid scramblase 3 (PLS3) is a newly recognized member of a family of proteins responsible for phospholipid translocation between two lipid compartments. A novel isoform of PLS3 is identified and characterized herein. The function of PLS3 in mitochondria was disrupted, yielding an inactive mutant PLS3(F258V). Cells transfected with PLS3(F258V) exhibited reduced proliferative capacity that was unaffected by the presence of Na 3 N. PLS3(F258V)-expressing cells exhibit abnormal mitochondrial metabolism and structure and were associated with decreased sensitivity to UV- and tBid-induced apoptosis, and diminished translocation of cardiolipin to the outer mitochondrial membrane. Cells transfected with wild-type PLS3 displayed increased sensitivity to apoptosis and enhanced cardiolipin translocation. These studies identify PLS3 as a regulator of mitochondrial structure and respiration, and cardiolipin transport in apoptosis.
With the advances in modern neonatal intensive care medicine in the last 20 years, survival of extremely preterm infants weighing less than 1500g (\< 3 lbs, 5 oz) has risen markedly. However, with this increased survival has come a marked increase in the number of infants with serious neurodevelopmental disabilities: Premature infants with birth weights less than 1500g who survive to go home are at significant risk for serious neurodevelopmental problems: cognitive and motor delays, blindness, deafness, and cerebral palsy. In a recent randomized, placebo-controlled clinical trial, we assessed whether giving mechanically ventilated preterm infants inhaled nitric oxide gas (iNO) for 1 week after birth decreased the incidence of death and chronic lung disease. An unanticipated outcome of that study (Schreiber et. al. 2003) and a subsequent study of those infants at 2 years of age (Mestan et. al. 2005) was that premature infants treated with inhaled nitric oxide (iNO) have improved neurodevelopmental outcomes and physical growth at 2 years corrected age, compared with placebo-treated infants (Mestan et. al. 2005). INO therapy, therefore, appears to be a new treatment to protect the premature brain during development outside the womb. The overall goal of this application is understand the efficacy of iNO treatment in improving neurodevelopmental outcomes in at-risk premature infants.
Advanced gastric cancer that has not invaded the greater curvature is a good indication for total gastrectomy (TG) with spleen-preserving suprapancreatic and splenic hilar lymph node dissection (LND). However, the suprapancreatic and splenic hilar LND increases the area of dissection of the pancreas, and prolonged pressure drainage of the pancreas is required to maintain a clear operative view. This can lead to an increased risk of postoperative pancreatic complications. To report the efficacy of our novel preemptive retropancreatic approach (PRA) for the suprapancreatic and splenic hilar LND in robotic TG (RTG). We report our experience with nine patients with gastric cancer who underwent spleen-preserving splenic hilar LND using PRA during RTG at Hokkaido University from October 2018 to November 2021. The PRA involves initial dissection of the left side of the retropancreatic space, followed by the release of the adherence between the retroperitoneum surface and the pancreas (fusion fascia), which provides a good operative field and prevents contact with the pancreas during the suprapancreatic and splenic hilar LND in RTG. The median operating time was 488 min (254-564 min). The median intraoperative bleeding was 55 mL (0-115 mL). One patient had postoperative complications (above grade II of the Clavien-Dindo classification), but there were no postoperative pancreatic complications. The spleen-preserving suprapancreatic and splenic hilar LND using PRA could help to reduce the postoperative pancreatic complications associated with RTG.Trial registration number and date of registration The Hokkaido University Hospital institutional review board approved the data collection and analysis. The trial registration number and date of registration are No. 021-0022 and July 26, retrospectively registered.

BACKGROUND: The study aimed to evaluate the agreement of prescribed drug dosages with renal dosing recommendations and describe adverse drug events (ADEs) contributing to hospital admissions of patients with chronic kidney disease (CKD).
METHODS: This cross-sectional study focused on CKD patients admitted to University Hospital Hradec Králové, with an estimated glomerular filtration rate below 60 ml/min. The necessity for renal dosage adjustments was determined using the Summary of Product Characteristics (SmPC). For medications requiring renal dosage adjustment according to SmPC, agreement between the prescribed and recommended renal dosage was assessed. ADEs were adjudicated using the OPERAM drug-related hospital admissions adjudication guide.
RESULTS: Of 375 CKD patients, 112 (30%, 95% CI 25-34) were prescribed drug dosages in disagreement with SmPC renal dosage recommendations. Perindopril, metformin, and ramipril were most frequently dosed in disagreement with SmPC. ADE-related hospital admissions occurred in 20% (95% CI 16-24) of CKD patients.
CONCLUSION: CKD patients are often prescribed medication dosages in disagreement with SmPC renal dosing recommendations. Besides explicit factors, treatment goals, feasibility of monitoring and alternative treatment must be weighed when assessing drug and dosage appropriateness. Gastrointestinal bleeding was the most frequent ADE that contributed to hospital admissions of CKD patients.
An injection formula for relieving virus symptoms is characterized by being prepared from the following raw materials in percentage by weight: 0.5-30% of zinc-containing compound, 0.0001-5% of target virus inactivated strain and 65-99.4999% of distilled water. The zinc-containing compound is a chemical substance containing zinc element which is soluble in water. The target virus inactivated strain is a protein set after target virus inactivation. The present invention provides a formulation that reduces the symptoms of a virus or novel virus infection when the immune system is able to function properly. The invention can be used in the severe stage of a new virus, but with the immune system still able to immunize normally, for the purpose of alleviating or eliminating symptoms. The present invention can reduce the toxicity and the speed of a virus when the immune system of the human body can produce correct and effective antibodies.
Oxidative stress and inflammation play a fundamental role in the beginning and advancement of silicosis. Hence, questing active phytocompounds (APCs) with anti-oxidative and anti-inflammatory properties such as diosgenin (DG) and emodin (ED) can be a therapeutic intervention targeting silica-induced pulmonary inflammation and fibrosis. Hydrophobicity and low bioavailability are the barriers that restrict the therapeutic efficacy of DG and ED against pulmonary defects. Encapsulating these APCs in polymeric nanoparticles can overcome this limitation. The present study has thus explored the anti-inflammatory and anti-fibrotic effects of polylactic-co-glycolic acid (PLGA) nanoparticles (NPs) individually loaded with DG (DGn) or ED (EDn) and in combine DG+ED [(DG+ED)n] in respirable silica dust (RSD)-induced pulmonary fibrosis silicosis rat model. Our study found that individual and combined NPs revealed physiochemical characteristics appropriate for IV administration with sustained-drug release purposes. Physiological evaluations of RSD-induced silicosis rats suggested that no treatment could improve the body weight. Still, they reduced the lung coefficient by maintaining lung moisture. Only (DG+ED)n significantly cleared free lung silica. All interventions were found to attribute the increased per cent cell viability in BALF, reduce cytotoxicity via minimizing LDH levels, and balance the oxidant-antioxidant status in silicotic rats. The expression of inflammatory cytokines (TNF-α, IL-1β, IL-6, MCP-1, and TGF-β1) were efficiently down-regulated with NPs interventions compared to pure (DG+ED) treatment. All drug treatments significantly declined, the 8-HdG and HYP productions indicate that RSD-induced oxidative DNA damage and collagen deposition were successfully repaired. Moreover, histopathological investigations proposed that individual or combined drugs NPs interventions could decrease the fibrosis and alveolitis grades in RSD-induced silicosis rats. However, (DG+ED)n intervention significantly inhibited pulmonary fibrosis and alveolitis compared to pure (DG+ED) treatment. In conclusion, the RSD can induce oxidative stress and inflammation in rats, producing reactive oxygen species (ROS)-mediated cytotoxicity to pulmonary cells and leading to silicosis development. The IV administration of combined NP suppressed lung inflammation and collagen formation by maintaining oxidant-antioxidant status and effectively interrupting the fibrosis-silicosis progression. These results may be attributed to the improved bioavailability of DG and ED through their combined nano-encapsulation-mediated targeted drug delivery.

Mexico has the highest diversity of snake species in the world, following Australia when considering just venomous snakes. Specifically, in Sonora, the second largest state in the country, more than 15 highly venomous species occur, including the northern black-tailed rattlesnake (Crotalus molossus). This specie's venom has not been as thoroughly researched in contrast with other Mexican vipers, nevertheless some studies report its biological activity and even pharmacological potential with antibacterial and cytotoxic activity. In this study we identified the main protein components from a pool of C. molossus venom through a gel-free proteomics approach, reporting ∼140 proteins belonging to the SVMP (38.76%), PLA2 (28.75%), CTL (11.93%), SVSP (6.03%) and LAAO (5.67%) toxin families. To study its biological activities, we evaluated its hemolytic, antibacterial, and cytotoxic activity in red blood cells, Gram positive and negative bacteria and a luminal A breast carcinoma cell line (T47D), respectively, in vitro. We report that concentrations <100 μg/mL are potentially not hemolytic and reduced the bacteria viability of E. coli and S. aureus with an IC50 of 10.27 and 11.51 μg/mL, respectively. Finally, we determined the C. molossus venom as cytotoxic against the T47D breast carcinoma cell line, with an IC50 of 1.55 μg/mL. We suggest that the evaluated cytotoxicity was due to a high abundance of SVMPs and PLA2s, since it's been reported that they affect the extracellular matrix and membrane permeation. This may provide a useful tool for pharmaceutical screening in the future.
INTRODUCTION: Penile squamous cell carcinoma (PSCC) can develop from human papillomavirus (HPV) infection. This study investigates if the prognostic value of the TNM stage groups or the components tumor stage (pT), grade of differentiation (Grade), lymphovascular invasion (LVI), and nodular stage (pN) depend on HPV status. Also, whether the value of tumor parameters (pT, Grade, and LVI) for predicting node-positive disease depends on HPV status was investigated.
PATIENTS AND METHODS: Stored tumor tissue from 226 patients treated for PSCC in Western Norway between 1973 and 2023 was investigated for HPV DNA. Histopathological variables were reevaluated according to the current TNM classification. Disease course was registered from hospital records. Inclusion of an interaction term between HPV and TNM stage groups in Cox regression enabled analysis of whether cancer-specific survival (CSS) of the stage groups depended on HPV status. This was also done separately for pT, Grade, LVI, and pN. Logistic regression with interaction terms between HPV and the tumor parameters were used to investigate if their predictive value depended on HPV status.
RESULTS: HPV DNA was detected in 43% of the tumors. Stratified by HPV status, there was no significant interaction term in the Cox regression between HPV status and TNM stage groups (P = .74). Similar results were found for pT (P = .94), Grade (P = .08), LVI (P = .91) and pN (P = .77). Moreover, there were no significant interaction terms in the logistic regression between HPV status and the tumor parameters pT, Grade, and LVI (all P > .2).
CONCLUSIONS: This study found that prognosis of the TNM stage groups and the components pT, Grade, LVI, and pN were not modified by HPV in PSCC. The value of pT, Grade, and LVI for predicting lymph node-positive disease was not affected by HPV status.
