The transcription factor farnesoid X receptor (FXR) regulates energy metabolism. Specifically, FXR functions to regulate cystic fibrosis transmembrane conductance regulator (CFTR)-mediated Cl- secretion in intestinal epithelial cells. Therefore, this study aimed to investigate the role of FXR in CFTR-mediated Cl- secretion in renal tubular cells and to further elucidate its effects on renal cyst formation and growth. CFTR-mediated Cl- transport was evaluated via short-circuit current (ISC) measurements in Madin-Darby canine kidney (MDCK) cell monolayers and primary rat inner medullary collecting duct cells. The role of FXR in renal cyst formation and growth was determined by the MDCK cell-derived cyst model. Incubation with synthesized (GW4064) and endogenous (CDCA) FXR ligands reduced CFTR-mediated Cl- secretion in a concentration- and time-dependent manner. The inhibitory effect of FXR ligands was not due to the result of reduced cell viability and was attenuated by cotreatment with an FXR antagonist. FXR activation significantly decreased CFTR protein but not its mRNA. In addition, FXR activation inhibited CFTR-mediated Cl- secretion in primary renal collecting duct cells. FXR activation decreased ouabain-sensitive ISC without altering Na+-K+-ATPase mRNA and protein levels. Furthermore, FXR activation significantly reduced the number of cysts and renal cyst expansion. These inhibitory effects were correlated with a decrease in the expression of protein synthesis regulators mammalian target of rapamycin/S6 kinase. This study shows that FXR activation inhibits Cl- secretion in renal cells via inhibition of CFTR expression and retards renal cyst formation and growth. The discoveries point to a physiological role of FXR in the regulation of CFTR and a potential therapeutic application in polycystic kidney disease treatment.NEW & NOTEWORTHY The present study reveals that farnesoid X receptor (FXR) activation reduces microcyst formation and enlargement. This inhibitory effect of FXR activation is involved with decreased cell proliferation and cystic fibrosis transmembrane conductance regulator-mediated Cl- secretion in renal collecting duct cells. FXR might represent a novel target for the treatment of autosomal dominant polycystic kidney disease.

The lateral line is critical for prey detection, predator avoidance, schooling, and rheotaxis behavior in fish. As similar to hair cells in the mammalian inner ear, the lateral line sensory organ called neuromasts is a popular model for hair cell regeneration. However, the mechanism of lateral line development has not been fully understood. In this study, we showed for the first time that hypoxia-inducible factor (HIF) signaling is involved in lateral line development in zebrafish. hif1ab and epas1b were highly expressed in neuromasts during lateral line development. Hypoxia response induced by a prolyl hydroxylase domain-containing proteins (PHD) inhibitor treatment or vhl gene knockout significantly reduced hair cells and support cells in neuromast during lateral line development. In addition, inhibition of Hif-1α or Epas1 could partially rescue hair cells in the larvae with increased HIF activity, respectively. Moreover, the support cell proliferation and the expression of Wnt target genes decreased in vhl mutants which suggests that Wnt signaling mediated the role of HIF signaling in lateral line development. Collectively, our results demonstrate that HIF signaling overactivation inhibits lateral line development in zebrafish and suggest that inhibition of HIF signaling might be a potential therapeutic method for hair cell death.
Alcohol-associated hepatitis (AH) is an acute-on-chronic liver injury that occurs in patients with chronic alcohol-associated liver disease (ALD). Patients with severe AH have high short-term mortality and lack effective pharmacologic therapies. Inflammation is believed to be one of the key factors promoting AH progression and has been actively investigated as therapeutic targets over the last several decades, but no effective inflammatory targets have been identified so far. In this review, we discuss how inflammatory cells and the inflammatory mediators produced by these cells contribute to the development and progression of AH, with focus on neutrophils and macrophages. The crosstalk between inflammatory cells and liver nonparenchymal cells in the pathogenesis of AH is elaborated. We also deliberate the application of recent cutting-edge technologies in characterizing liver inflammation in AH. Finally, the potential therapeutic targets of inflammatory mediators for AH are briefly summarized.
Monthly Plasmapheresis (plasma exchange machine: Haemonetics, model TCS2, USA) 25 ml/kg for 5 cycles, with replacement of 0.9% saline and 5% human serum albumin followed by monthly IV infusion of 12 mg/m2 mitoxantrone (EBEWE Pharma, Amsterdam, The Netherlands) at the end of each Plasmapheresis course for three successive months. Then, treatment is continued by adding two more 6 mg/m2 doses of mitoxantrone in 3-month intervals.
AIM: The trial (NCT04016974) investigated the pharmacokinetics, pharmacodynamics, safety and tolerability of oral semaglutide, the first orally administered glucagon-like peptide-1 analogue for type 2 diabetes, in healthy Chinese subjects.
MATERIALS AND METHODS: This single-centre, multiple-dose, placebo-controlled trial randomized 32 healthy Chinese adults to once-daily oral semaglutide (3 mg escalating to 14 mg) or placebo for 12 weeks. Blood samples were collected regularly during treatment and follow-up. The primary endpoint was the area under the semaglutide concentration-time curve over a dosing interval (0-24 h) at steady state (AUC0-24h,sema,SS). Secondary pharmacokinetic endpoints included the maximum observed semaglutide plasma concentration at steady state (Cmax,sema,SS). Supportive secondary pharmacodynamics endpoints included changes in body weight and fasting plasma glucose.
RESULTS: Treatment with all oral semaglutide doses showed dose-dependent increases in semaglutide exposure in healthy Chinese subjects at steady state, determined by AUC0-24h,sema,SS (233, 552 and 1288 h·nmol/L for 3, 7 and 14 mg of oral semaglutide, respectively) and Cmax,sema,SS. Oral semaglutide treatment was associated with significant reductions in body weight (p = .0001) and fasting plasma glucose (p = .0011) versus placebo at the end of treatment. The safety and tolerability of oral semaglutide were consistent with the known profile of glucagon-like peptide-1 receptor agonists, with no severe or blood-glucose-confirmed symptomatic hypoglycaemic events, serious adverse events or deaths. The most frequent adverse events were gastrointestinal disorders.
CONCLUSIONS: At steady state, oral semaglutide exposure was dose dependent and close to dose proportionality in healthy Chinese subjects. This is consistent with previous clinical pharmacology results for oral semaglutide.
Cancer-associated fibroblasts (CAFs) assist in breast cancer (BRCA) invasion and immune resistance by overproduction of extracellular matrix (ECM). Herein, we develop FPC@S, a photodynamic immunomodulator that targets the ECM, to improve the photodynamic immunotherapy for fibrotic BRCA. FPC@S combines a tumor ECM-targeting peptide, a photosensitizer (protoporphyrin IX) and an antifibrotic drug (SIS3). After anchoring to the ECM, FPC@S causes ECM remodeling and BRCA cell death by generating reactive oxygen species (ROS) in situ. Interestingly, the ROS-mediated ECM remodeling can normalize the tumor blood vessel to improve hypoxia and in turn facilitate more ROS production. Besides, upon the acidic tumor microenvironment, FPC@S will release SIS3 for reprograming CAFs to reduce their activity but not kill them, thus inhibiting fibrosis while preventing BRCA metastasis. The natural physical barrier formed by the dense ECM is consequently eliminated in fibrotic BRCA, allowing the drugs and immune cells to penetrate deep into tumors and have better efficacy. Furthermore, FPC@S can stimulate the immune system and effectively suppress primary, distant and metastatic tumors by combining with immune checkpoint blockade therapy. This study provides different insights for the development of fibrotic tumor targeted delivery systems and exploration of synergistic immunotherapeutic mechanisms against aggressive BRCA.
Ataxia with anti-regulator of G-protein signaling 8 autoantibodies (RGS8-Abs) is an autoimmune disease recently described in four patients. The present study aimed to identify other patients with RGS8-Abs, describe their clinical features, including the link between RGS8-related autoimmune cerebellar ataxia (ACA) and cancer. Patients with RGS8-Abs were identified retrospectively in the biological collections of the French Reference Center for Paraneoplastic Neurological Syndrome and the University of California San Francisco Center for Encephalitis and Meningitis. Clinical data were collected, and cerebrospinal fluid, serum, and tumor pathological samples were retrieved to characterize the autoantibodies and the associated malignancies. Only three patients with RGS8-Abs were identified. All of them presented with a pure cerebellar ataxia of mild to severe course, unresponsive to current immunotherapy regimens for ACA. Two patients presented with a Hodgkin lymphoma of the rare specific subtype called nodular lymphocyte-predominant Hodgkin lymphoma, with very mild extension. Autoantibodies detected in all patients enriched the same epitope on the RGS8 protein, which is an intracellular protein physiologically expressed in Purkinje cells but also ectopically expressed specifically in lymphoma cells of patients with RGS8-related ACA. The present results and those of the four cases previously described suggest that RGS8-Abs define a new paraneoplastic neurological syndrome of extreme rarity found mostly in middle-aged males that associates pure cerebellar ataxia and a particular lymphoma specifically expressing the RGS8 antigen. As in other paraneoplastic ACA with intracellular antigen, the disease course is severe, and patients tend to exhibit a poor response to immune therapy.
BACKGROUND: Acute type A aortic intramural hematoma (ATAIMH) is a variant of acute type A aortic dissection (ATAAD), exhibiting an increased risk of hemopericardium and cardiac tamponade. It can be life-threatening without emergency treatment. However, comprehensive studies of the clinical features and surgical outcomes of preoperative hemopericardium in patients with ATAIMH remain scarce. This retrospective study aims to investigate the clinical features and early and late outcomes of patients who underwent aortic repair surgery for ATAIMH complicated with preoperative hemopericardium.
METHODS: We investigated 132 consecutive patients who underwent emergency ATAIMH repair at this institution between February 2007 and August 2020. These patients were dichotomized into the hemopericardium (n = 58; 43.9%) and non-hemopericardium groups (n = 74; 56.1%). We compared the clinical demographics, surgical information, postoperative complications, 5-year cumulative survival rates, and freedom from reoperation rates. Furthermore, multivariable logistic regression analysis was utilized to identify independent risk factors for patients who underwent re-exploration for bleeding.
RESULTS: In the hemopericardium group, 36.2% of patients presented with cardiac tamponade before surgery. Moreover, the hemopericardium group showed higher rates of preoperative shock and endotracheal intubation and was associated with an elevated incidence of intractable perioperative bleeding, necessitating delayed sternal closure for hemostasis. The hemopericardium group exhibited higher blood transfusion volumes and rates of re-exploration for bleeding following surgery. However, the 5-year survival (59.5% vs. 75.0%; P = 0.077) and freedom from reoperation rates (93.3% vs. 85.5%; P = 0.416) were comparable between both groups. Multivariable analysis revealed that hemopericardium, cardiopulmonary bypass time, and delayed sternal closure were the risk factors for bleeding re-exploration.
CONCLUSIONS: The presence of hemopericardium in patients with ATAIMH is associated with an elevated incidence of cardiac tamponade and unstable preoperative hemodynamics, which could lead to perioperative bleeding tendencies and high complication rates. However, patients of ATAIMH complicated with hemopericardium undergoing aggressive surgical intervention exhibited long-term surgical outcomes comparable to those without hemopericardium.

Potential subjects will undergo Screening for eligibility based on Inclusion/Exclusion criteria. Screening will include an x-ray of the injured knee and evaluation of an MRI of the injured knee within 6 months prior to the scheduled procedure. During the procedure, the meniscal tear will be evaluated by arthroscopy to determine if the tear meets study requirements. If the meniscal tear is determined to meet inclusion/exclusion criteria, the subject will be considered enrolled. If any inclusion/exclusion criteria is not met, the subject will be considered a screen failure and will not be enrolled. For enrolled subjects, specific information regarding the repair and repair technique will be collected during the procedure, including still and video images.

Subjects will be contacted 7-15 days post-procedure for safety follow-up. Subjects will return for follow-up visits at approximately post-procedure Days 90, 185, 365 and 730. Identical questionnaires will be completed at each visit to assess knee pain and knee function. Safety information will be collected at each post-procedure visit. Additionally, an in-office arthroscopy of the treated knee will be performed at participating sites at Day 185, an MRI of the treated knee will be performed at Day 365 and an X-ray of the treated knee will be performed at Day 730. The patient will exit the study at the Day 730 visit.
A primigravida in her late 20s presented to the obstetrics and gynaecology department in labour. On per speculum examination, multiple cystic lesions, 1-5 mm in size were observed occupying the anterior, posterior and lateral vaginal walls. Vaginal wet mount was normal and vaginal cultures were negative. Biopsy findings were consistent with emphysematous vaginitis. Vaginitis emphysematosa is a rare, benign self-limiting condition that presents with multiple, air-filled cysts in the vaginal or ectocervical mucosa. This condition is seen in both gravid and non gravid women, usually associated with a Trichomonas or Gardnerella infection.

Intervention/Procedure: Rapid maxillary expansion. When RME was in situ, patients started the screw activation (Snap-lock expander screw, Forestadent, Pforzheim, Germany) of one-quarter turn a day (0.22 mm) until overcorrection was achieved (ie, the occlusal surface of the first maxillary palatal cusp contacted the occlusal surface of the mandibular first molar facial cusp), and the RME remained in place for 10 months. The screw was turned for 41 ± 8 days, and the average treatment time was 12 ± 1.3 months.
Individuals with disabilities rely heavily on unpaid family caregivers to help perform necessary occupations. The emotional and physical demands of caregiving often contribute to caregivers experiencing burden. Caregivers with burden are at-risk for poor health and a heightened risk of mortality. This is likely, in turn, to negatively impact care-recipient quality of life. The proposed study refines a behavioral intervention that teaches caregivers to facilitate problem solving over the course of daily activities. The long-term goal for this project is to establish an effective rehabilitation intervention that promotes caregiver health and well-being, which ultimately influences care-recipient health. This study will use an open-case series and a single-arm clinical trial to refine the intervention and examine caregiver and care-recipient response to the intervention. This research applies to the priorities and objectives of this research initiative through examination of a caregiver-centered, standardized intervention that is based on occupational theories and principles, investigating outcomes experienced by caregivers of individuals with cognitive deficits after stroke. Data from this pilot project will be used to design and obtain federal funding for a randomized controlled trial to examine the efficacy of the refined intervention on caregiver and care-recipient health outcomes.

Participants in this arm receive the WE Harambee Wellness Enhancement and are enrolled in a Behavioral Health Home. WE Harambee is a 6-month peer-delivered whole health intervention intended to address the 8 dimensions of wellness and the social determinants of health.
This invention relates to a novel method of treating various inflammation-related anorectal and genitourinary conditions using various related, novel formulations. The formulations comprise, at a minimum, a corticosteroid, an antidepressant agent(s) with anti-allergic and/or anti-itch properties and a cooling/soothing agent(s). Selection of specific ingredients depends on the nature of the target tissues, the etiologies of inflammation and the severity of symptoms. To maximize its efficacy, each of the formulations has a unique combination of several active ingredients, and each of these ingredients exerts its anti-inflammatory effect at various phases of the inflammatory cascade, resulting in a synergistic effect of pain relief and healing. To minimize the side effects, the current multi-active ingredient formulations allow each of these ingredients to exist at a lower concentration than the existing single-active ingredient formulations, thus minimizing the likelihood for side effects due to systemic absorption and toxicity. The formulations are highly versatile in that the composition of the ingredients can be varied and adjusted to treat a wide array of anorectal and genitourinary conditions.
The investigators will randomize primary care providers (PCPs) at the VA Portland Health Care System to either ISOP or the control condition; patients will be nested by clinician status. All PCPs who enroll will participate in either a two-hour educational workshop or the two-hour educational workshop + nurse care manager (NCM). The NCM will maintain a registry of enrolled patients, track opioid medication-related events from the medical record, and provide decision support to PCPs for issues related to prescription opioid safety. The NCM will also meet individually with enrolled participants to discuss strategies for preventing/reducing opioid side effects, preventing diversion, and providing rationale for screening for prescription opioid misuse. The investigators will recruit patients who are already prescribed chronic opioid therapy for chronic non-cancer pain. Participants will be enrolled for one year. Outcomes will be measured at baseline, and 6 and 12 months after enrollment.
PURPOSE: To prepare a concentrate of a highly specific active antihemophilic factor(AHF) without containing a nonhuman protein by dissolving a low- temperature precipitate and successively carrying out the treatment with a PEG, viral inactivating treatment and gel filtration. CONSTITUTION: A low-temperature precipitate is recovered from a thawed pool of a fresh frozen human blood plasma by the centrifugation and water for injection(WFI) is added thereto and dissolved therein. Aluminum hydroxide is then added thereto to adsorb a vitamin K-dependent factor thereon. A polyethylene glycol(PEG) is added at 20-25 deg.C to precipitate and remove a nonAHF protein. A mixture of glycine with NaCl is added to an eluate containing the AHF to precipitate the AHF. The resultant AHF is further dissolved and viruses are inactivated by treatment with a chemical and the prepared solution is then passed through a filtration column containing a size exclusion resin to remove the chemical. The AHF is isolated to at least 35 units of factor VIII activities based on 1mL pooled concentrate.
In the IV PCA group, the surgeon performed local infiltration with 40 mL of 0.25% bupivacaine around the incisions. All patients were provided postoperative analgesia with intravenous patient-controlled analgesia (IVHKA). When pain was expressed by the patient, the patient pressed a button and the IV HKA pump was programmed to deliver a 1 ml bolus dose with a 10-minute lockout interval and no background infusion allowed. Each 1 ml of IVHKA solution contains 1 mg of morphine.
PURPOSE:To obtain a cosmetic raw material effective for the early recovery of dermatic fatigue, bleaching of pigment, prevention of aging, prevention of wrinkle, etc., by decomposing a sclero-protein conchiolin with sulfuric acid, neutralizing the product in two steps and removing the produced precipitate. CONSTITUTION:Conchiolin which is a scleroprotein existing in pearl and various shells is decomposed and subjected to the first neutralization with Ba(OH)2 to 2.5-2.7pH and then to the second neutralization with NaOH, etc., to 5-6pH. The objective cosmetic raw material is produced e.g. by cooling the neutralization product and removing the formed precipitate by centrifugal separation, filtration, etc. The sulfuric acid decomposition is carried out by using an aqueous solution of sulfuric acid having a concentration of 0.5-20% and the scleroprotein is hydrolyzed at a temperature controlled to 0-150 deg.C for 30 min-10 days. The characteristic skin-beautifying effect of the scleroprotein is maintained in the cosmetic raw material in spite of the removal of the sensitizing substance.
