BACKGROUND: The potent antiplasmodial activity of 1-hydroxy-5,6,7-trimethoxyxanthone (HTX), isolated from Mammea siamensis T. Anders. flowers, has previously been demonstrated in vitro. However, its in vivo activity has not been reported. Therefore, this study aimed to investigate the antimalarial activity and acute toxicity of HTX in a mouse model and to evaluate the pharmacokinetic profile of HTX following a single intraperitoneal administration.
METHODS: The in vivo antimalarial activity of HTX was evaluated using a 4-day suppressive test. Mice were intraperitoneally injected with Plasmodium berghei ANKA strain and given HTX daily for 4 days. To detect acute toxicity, mice received a single dose of HTX and were observed for 14 days. Additionally, the biochemical parameters of the liver and kidney functions as well as the histopathology of liver and kidney tissues were examined. HTX pharmacokinetics after intraperitoneal administration was also investigated in a mouse model. Liquid chromatography triple quadrupole mass spectrometry was used to quantify plasma HTX and calculate pharmacokinetic parameters with the PKSolver software.
RESULTS: HTX at 10 mg/kg body weight significantly suppressed parasitemia in malaria-infected mice by 74.26%. Mice treated with 3 mg/kg HTX showed 46.88% suppression, whereas mice treated with 1 mg/kg displayed 34.56% suppression. Additionally, no symptoms of acute toxicity were observed in the HTX-treated groups. There were no significant alterations in the biochemical parameters of the liver and kidney functions and no histological changes in liver or kidney tissues. Following intraperitoneal HTX administration, the pharmacokinetic profile exhibited a maximum concentration (Cmax) of 94.02 ng/mL, time to attain Cmax (Tmax) of 0.5 h, mean resident time of 14.80 h, and elimination half-life of 13.88 h.
CONCLUSIONS: HTX has in vivo antimalarial properties against P. berghei infection. Acute toxicity studies of HTX did not show behavioral changes or mortality. The median lethal dose was greater than 50 mg/kg body weight. Pharmacokinetic studies showed that HTX has a long elimination half-life; hence, shortening the duration of malaria treatment may be required to minimize toxicity.
Background: one of the major clinical concerns of prosthetic haemodialysis access is the risk of possible restenosis after stenosis dilatation. Only 25% of dilated prosthetic haemodialysis vascular accesses remain patent at one year. No available pharmacological agents can yet effectively prevent it. After stenosis dilatation the vascular wall responds to mechanical injury in a standardized manner: intimal smooth-muscle cells migrate and proliferate, a neointima gradually begins to form and the cell phenotype changes from contractile to secretory. One way to inhibit the neointimal proliferation responsible for restenosis is to induce cell apoptosis by delivering ionizing radiations to the dilated area after the endovascular procedure. Experimental studies and multicenter clinical trials have reported the beneficial effects of endovascular beta or gamma ionizing radiation on vascular restenosis. Experimental studies in animals and recent clinical trials clearly show that external irradiation also reduces neointimal proliferation after arterial injury thus opening the way for the clinical assessment of ionizing radiations on arteries. In a previous experimental study, we reported that irradiation has a dose-dependent effect on the prevention of restenosis: a dose larger than 10 Gy is needed to obtain a significant reduction of intimal hyperplasia.

Objective: the main objective is to assess external ionizing radiation for restenosis prevention on prosthetic haemodialysis vascular accesses after angioplasty. A secondary objective is to assess the treatment safety.

Methods: Single blind randomized clinical trial on two parallel groups of 53 patients each. Patients with chronic renal failure treated by dialysis will be included after a successful angioplasty on a stenosis of the vein adjacent to their prosthetic haemodialysis vascular access. One group will be treated by a single dose of ionizing radiations (14 Gy) at day 1 after angioplasty. The control group will not receive any preventive treatment. The primary outcome is the one-year vascular access patency failure. Secondary outcomes are the one-year delay of occurrence of a restenosis and the treatment safety. Outcomes will be assessed by a clinical and ultrasonographic (at 1, 3, 6 and 12 months, or at other time points in case of stenosis suspicion) follow-up.
BACKGROUND: Previous research has reported that prenatal exposure to dexamethasone (PDE) results in organ dysplasia and increased disease susceptibility in offspring. This study aimed to investigate the epigenetic mechanism of metabolic syndrome induced by PDE in offspring.
METHODS: Pregnant Wistar rats were administered dexamethasone, and their offspring's serum and liver tissues were analyzed. The hepatocyte differentiation model was established to unveil the molecular mechanism. Neonatal cord blood samples were collected to validate the phenomenon and mechanism.
RESULTS: The findings demonstrated that PDE leads to insulin resistance and typical metabolic syndrome traits in adult offspring rats, which originated from fetal liver dysplasia. Additionally, PDE reduced serum corticosterone level and inhibited hepatic insulin-like growth factor 1 (IGF1) signaling in fetal rats. It further revealed that liver dysplasia and functional impairment induced by PDE persist after birth, driven by the continuous downregulation of serum corticosterone and hepatic IGF1 signaling. Both in vitro and in vivo experiments confirmed that low endogenous corticosterone reduces the histone 3 lysine 9 acetylation (H3K27ac) level of IGF1 and its expression by blocking glucocorticoid receptor α, special protein 1, and P300 into the nucleus, resulting in hepatocyte differentiation inhibition and liver dysplasia. Intriguingly, neonatal cord blood samples validated the link between reduced liver function in neonates induced by PDE and decreased serum cortisol and IGF1 levels.
CONCLUSIONS: This study demonstrated that low endogenous glucocorticoid level under PDE lead to liver dysplasia by downregulating the H3K27ac level of IGF1 and its expression, ultimately contributing to metabolic syndrome in adult offspring.
China is the country with the second highest Tuberculosis (TB) burden in the world. Most of the retreatment TB patients may develop multi-drug resistant. The resistant rate of any of the anti-TB drug is 35.9%, and the multi-drug resistant rate is 15.4%. Retreatment TB becomes one of the factors which inhibit the decrease of morbidity and mortality of TB. It is also a tuff work in TB control. At present the standardized regimen for retreatment TB is 2SHREZ/6HRE or 3HREZ/6HRE. The drugs in the regimen are all first-line anti-TB drugs which are unsuitable for the high drug resistance prevalence, because the cure rate of this regimen is low and the adverse reaction is severe.

Our study is a national multi-center, prospective trail to investigate the efficacy of a new super-short regimen for retreatment TB patients. The new regimen consists of 5 drugs lasting 5 months. The cure rate and success rate of the new regimen is compared with standardized regimen usually 8-9 months in order to obtain the optimized regimen.
Premedication represents an important part in the perioperative management of children and is used to reduce pre-operative stress as well as to facilitate induction of inhaled anaesthesia. Midazolam is the drug most often used for premedication in infants and children because it provides good sedation, anxiolytic and amnestic effects and few side effects. Oral intake of the drug is the most preferred route of administration by paediatric patients, whereas the majority of existing oral Midazolam solutions involve the use of i.v. Midazolam formulation given orally, unregistered or off-label. Moreover i.v. Midazolam solutions are often not well accepted by children because of their bitter taste. Considering the lack of available oral medications for moderate sedation in children in most European countries, ADV6209, an innovative 0.2% (w/v) oral solution of Midazolam for children from six months of age, was developed. The formation of a γ-Cyclodextrin -Midazolam complex, representing a new chemical formula, was used to improve the solubility and the palatability of the Midazolam formulation. A pharmacokinetic (PK) study has been executed in adults, children and adolescents, whereas ADV6209 showed improvements to current extemporaneous oral solutions of midazolam (EOM) preparations in terms of taste and easiness of use while presenting a similar PK profile. Satisfying sedation, measured with the Observer Assessment of Alertness/Sedation Scale (OAA score / S≤17) was observed in 78.4% of paediatric patients 30 minutes after ADV6209 administration. Anxiety score (modified Yale Preoperative Anxiety Scale - mYPAS) was decreased by 18.3% on average over baseline, 30 minutes after ADV6209 with a more pronounced effect in the youngest children who were also the most anxious prior to administration of the drug. In general the treatment was well accepted by all children and did not induce more crying and nausea / vomiting than before Midazolam. ADV6209 seems a very promising premedication drug. It has been licensed by the EU regulatory authorities to become the first licensed paediatric sedative in the EU (September 2018). It may help to avoid unregistered and off label use of EOM. Consequently, we want to evaluate the efficacy and safety of ADV6209 on preoperative anxiety and sedation levels in paediatric anaesthesia in daily clinical routine in this randomized, controlled, double blinded study.

Phase II glioblastoma (GBM) participants received the regimen established in the Phase I study (Feb 2011). Phase II participants received bevacizumab 10 mg/kg intravenously (IV) on days 1 and 15 of each 28 day cycle and LBH589 30 mg/day orally, 3x per week, every other week (Days 1, 3, 5, 15, 17, 19). Participants were treated until disease progression or unacceptable toxicity.
Antibiotic resistance is a paramount global health issue, with numerous bacterial strains continually fortifying their resistance against diverse antibiotics. This surge in resistance levels primarily stems from the overuse and misuse of antibiotics in human, animal, and environmental contexts. In this study, we advocate for exploring alternative molecules exhibiting antibacterial properties to counteract the escalating antibiotic resistance. We identified a synthetic antimicrobial peptide (AMP) by using computational search in AMP public databases and further engineering through molecular docking and dynamics. Microbiological evaluation, cytotoxicity, genotoycity, and hemolysis experiments were then performed. The designed AMP underwent rigorous testing for antibacterial and antibiofilm activities against Methicillin-Resistant Staphylococcus aureus (MRSA) and Escherichia coli (E. coli), representing gram-positive and gram-negative bacteria, respectively. Subsequently, the safety profile of the AMP was assessed in vitro using human fibroblast cells and a human blood sample. The selected AMP demonstrated robust antibacterial and antibiofilm efficacy against MRSA and E. coli, with an added assurance of non-cytotoxicity and non-genotoxicity towards human fibroblasts. Also, the AMP did not demonstrate any hemolytic activity. Our findings emphasize the considerable promise of the AMP as a viable alternative antibacterial agent, showcasing its potential to combat antibiotic resistance effectively.
OBJECTIVES: I. Determine the maximum tolerated dose of LY293111 in patients with advanced solid tumors. II. Determine the safety profile and pharmacokinetics of this regimen in these patients. III. Determine the antitumor activity of this regimen in these patients.

OUTLINE: This is a dose escalation study. Patients receive oral LY293111 twice daily. Treatment continues for a maximum of 6 months in the absence of disease progression or unacceptable toxicity. Cohorts of 3-6 patients receive escalating doses of LY293111 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 6 patients experience dose limiting toxicity. Additional patients are treated at the MTD. Patients are followed at 30 days.

PROJECTED ACCRUAL: Approximately 24 patients will be accrued for this study.
Parkinson's disease (PD) affects millions of people's lives worldwide. The main pathogenesis of PD is dopaminergic neuron necrosis and neuroinflammation mediated by activated microglia cells. In recent years, the anti-inflammatory ability and neuroprotective effects of miR-124 in PD models were well proved, but the in vivo delivery of miR-124 remains challenging. Herein, we report a protein nanosystem modified with a brain-targeting peptide ApoE that could efficiently deliver miR-124 across the blood-brain barrier (BBB). This nanosystem showed good cell viability on brain endothelial cells and microglia cells, and administration of this nanosystem significantly decreased the neuroinflammation and dopaminergic neuron loss, as well as recovered parts of neurobehavioral deficits. This ApoE peptide-based protein nanosystem holds great promise for the delivery of RNA therapeutics to the brain and for realizing neuron protection in PD treatment.

BACKGROUND: The aim of the study was to identify the variables of the internal compensatory mechanisms that differentiate the body build and posture of people with Down syndrome (DS) from the intellectual disability (ID) population. It was assumed that gaining knowledge in the abovementioned aspect will allow for a better understanding of the limitation of the kinesthetic abilities of people with ID and DS and simultaneously enable to optimize the process of planning and interventions to improve physical activity in this population with the adequate use of theirs strengths in the biomechanical and morphofunctional systems.
METHODS: The methodology of this systematic review was developed according to the PRISMA guidelines. A search of PubMed, EBSCO, Scopus databases was conducted to identify all studies on DS/ID and the body build and posture from 2003 to 2023.
RESULTS: 395 articles were assessed to determine eligibility, while 22 studies met the inclusion criteria and were subjected to detailed analysis and assessment of their methodological quality. The differentiation of the body build and posture in DS population can be induced by both internal and external compensatory mechanisms. It is difficult to confirm the direct effect of the intrinsic variables that impact the body build and posture in the ID population, excluding people with DS.
CONCLUSIONS: Compared to other ID, the intrinsic differences in the body build and posture in DS individuals were induced by gender, age, and level of ID. The tendency for diversity between DS and other ID populations in body build and posture may be determined by the presence of the third copy of chromosome 21 in DS group. Internal compensatory processes may be induced mainly by abnormalities in the structure of the cervical vertebrae and feet. IQ should not be used as the only variable that identifies the population of people with ID.

BACKGROUND: Irritable bowel syndrome (IBS) and functional dyspepsia (FD) are common disorders of gut-brain interaction (DGBI). The Rome IV criteria are the gold standard for research when diagnosing DGBI. However, bothersomeness, or the degree to which symptoms are distressing or disruptive to a person's daily life, is a potential treatment-seeking motivator that is not assessed by the Rome criteria. The Rome Foundation developed and published diagnostic criteria for clinical practice that include bothersomeness. We aimed to evaluate these constructs via patient focus groups to determine what prompts healthcare-seeking as a means to assess its value in the Rome clinical criteria.
METHODS: Adults meeting Rome IV criteria for IBS, FD, or both participated in focus groups in Australia and the United States. Semi-structured interview transcripts were analyzed using Template Thematic Analysis, with three a priori and other a posteriori themes refined iteratively through team discussion and consensus.
KEY RESULTS: Participants confirmed the frequency and duration of symptoms was not sufficient to reflect illness experience. Four major themes emerged: (1) Bothersomeness should be included in assessments of IBS and FD; (2) Patients find many DGBI symptoms bothersome; (3) Bothersomeness traverses multiple domains of quality of life; (4) Patients may hesitate to seek medical advice due to past negative experiences.
CONCLUSIONS AND INFERENCES: These findings support the value of the Rome Clinical Criteria. They emphasize the importance of expanding assessments of patients with DGBI to include how bothersome they perceive symptoms to be, how much symptoms interfere with their daily life, and what may moderate their decisions to seek treatment.
The role of inflammation is increasingly understood to have a central influence on therapeutic outcomes and prognosis in lung adenocarcinoma (LUAD). However, the detailed molecular divisions involved in inflammatory responses are yet to be fully elucidated. Our study identified two main inflammation-oriented LUAD grades: the inflammation-low (INF-low) and the inflammation-high (INF-high) subtypes. Both presented with unique clinicopathological features, implications for prognosis, and distinctive tumor microenvironment profiles. Broadly, the INF-low grade, marked by its dominant immunosuppressive tumor microenvironment, was accompanied by less favorable prognostic outcomes and a heightened prevalence of oncogenic mutations. In contrast, the INF-high grade exhibited more optimistic clinical trajectories, underscored by its immune-active environment. In addition, our efforts led to the conceptualization and empirical validation of an inflammation-centric predictive model with considerable predictive potency. Our study paves the way for a refined inflammation-centric LUAD classification and fosters a deeper understanding of tumor microenvironment intricacies.
The incidence of concomitant thyroid cancer in Graves' disease varies and Graves' disease can make the diagnosis and management of thyroid nodules more challenging. Since the majority of Graves' disease patients primarily received non-surgical treatment, identifying biomarkers for concomitant thyroid cancer in patients with Graves' disease may facilitate planning the surgery. The aim of this study is to identify the biomarkers for concurrent thyroid cancer in Graves' disease patients and evaluate the impact of being overweight on cancer risk. This retrospective cohort study analyzed 122 patients with Graves' disease who underwent thyroid surgery at Seoul St. Mary's Hospital (Seoul, Korea) from May 2010 to December 2022. Body mass index (BMI), preoperative thyroid function test, and thyroid stimulating hormone receptor antibody (TR-Ab) were measured. Overweight was defined as a BMI of 25 kg/m² or higher according to the World Health Organization (WHO). Most patients (88.5%) underwent total or near-total thyroidectomy. Multivariate analysis revealed that patients who were overweight had a higher risk of malignancy (Odds ratios, 3.108; 95% confidence intervals, 1.196-8.831; p = 0.021). Lower gland weight and lower preoperative TR-Ab were also biomarkers for malignancy in Graves' disease. Overweight patients with Graves' disease had a higher risk of thyroid cancer than non-overweight patients. A comprehensive assessment of overweight patients with Graves' disease is imperative for identifying concomitant thyroid cancer.
