Lengthy non-coding RNA RP11-84C13.A single stimulates osteogenic difference associated with bone tissue mesenchymal base tissues and reduces brittle bones progression using the miR-23b-3p/RUNX2 axis.
Cyanide is a rapid acting, lethal, metabolic poison and remains a significant threat. Current FDA-approved antidotes are not amenable or efficient enough for a mass casualty incident.

The objective of this study is to evaluate short and long-term efficacy of intramuscular aqueous dimethyl trisulfide (DMTS) on survival and clinical outcomes in a swine model of cyanide exposure.

Anesthetized swine were instrumented and acclimated until breathing spontaneously. Potassium cyanide infusion was initiated and continued until 5 min after the onset of apnea. Subsequently, animals were treated with intramuscular DMTS (
 = 11) or saline control (
 = 10). Laboratory values and DMTS blood concentrations were assessed at various time points and physiological parameters were monitored continuously until the end of the experiment unless death occurred. A subset of animals treated with DMTS (
 = 5) were survived for 7 days to evaluate muscle integrity by repeat biopsy and neurobehavioral outcomes.

Physiological par aqueous DMTS improves survival following cyanide poisoning with no observed long-term effects on muscle integrity at the injection site or adverse neurobehavioral outcomes.
In cognitive behavioral therapy (CBT) for social anxiety disorder (SAD), avoidance behavior (AB) and cognitions (COG) are two important targets of intervention, but so far no studies have directly examined their relative importance. By means of cross-lagged panel models (CLPM), we examined their temporal associations and impacts on outcome in clients with symptoms of SAD while addressing typical methodological challenges.

We used data from the first six therapy sessions in a sample of 428 primary care clients (mean [SD] age = 34.6 [12.2], 34.3% men), participating in the Prompt Mental Health Care trial. Session-by-session data was collected on AB, COG, depression and general anxiety. Competing multiple indicator CLPMs were tested.

The Random Intercept-CLPM provided best fit, and indicated that AB predicted COG at subsequent time points (.39 ≤ 
  ≤ .42 for T2-T5,
  < .05), but not vice versa. In addition, AB, but not COG, predicted clients' general anxiety score at subsequent time points. Results were both robust to the inclusion of depressive symptoms as a within-level covariate, and sensitivity tests for stationarity and missing data assumptions.

Targeting avoidance behavior for primary care clients with symptoms of SAD may be more vital for the optimal effect of CBT than targeting cognitions. Methodological considerations and limitations of the study are discussed.

This approach enabled the authors to successfully treat VHs of uncertain aetiology with cholinesterase inhibitors because the content of the hallucinations suggested dysfunction in cholinergic modulated networks.Methods We utilise the single case report to describe the nature and content of chronic VHs experienced by a 49-year-old woman following a prolonged admission to ITU. Despite extensive investigation, no clear cause was identified for these hallucinations and the patient did not respond to rationalisation of medications or trials of antipsychotics. We therefore adopted the neurophenomenological approach to classifying and treating her VHs.Results After several years of distressing visual hallucinations, a course of Rivastigmine was trialed despite no evidence suggestive of a Parkinsonian syndrome. Nevertheless, the patient reported a dose-effect response with significant reduction in the frequency and intensity of her hallucinations, almost to complete resolution.Conclusions At present there is limited evidence about the medical management of visual hallucinations. This case report suggests that cholinesterase inhibitors may be of benefit, even in the absence of clear parkinsonsian features, if the form and content of the VHs suggest dysfunction in cholinergic modulated attentional networks.This study aims to shed light on the phytochemical composition and the biological effect of two members of family Aizoaceae, Lampranthus glaucus and Lampranthus aurantiacus. Gas chromatography coupled to mass spectrometry (GC-MS) and high-performance liquid chromatography (HPLC) was used to investigate the lipoidal matter and the phenolic content, respectively. The MTT assay was used to evaluate the cytotoxic activity against MCF-7 (breast cancer), HepG2 (liver cancer) and HCT-116 (colorectal cancer) cell lines. The total phenolic acids and the total flavonoid content of L. glaucus were found to be higher than that of L. aurantiacus. Phytol, hexadecanoic acid, p-coumaric, ferulic and p- hydroxybenzoic acids were the major detected compounds. Both the petroleum ether and the ethyl acetate extracts of the two plants showed significant cytotoxic activity (IC50 ranging from 15to 27 µg/mL) against the tested cell lines compared to 5-fluorouracil used as a reference standard.Gastric cancer (GC) remains a major public health problem. Ursolic acid (UA) is reported to be effective in inhibiting GC; however, its low solubility and poor biocompatibility have greatly hindered its clinical application. Herein, an innovative reactive oxygen species (ROS)-sensitive UA dimeric prodrug is developed by coupling two UA molecules via a ROS-cleavable linkage, which can self-assemble into stable nanoparticles in the presence of surfactant. This new UA-based delivery system comprises the following major components (I) dimeric prodrug inner core that can achieve high drug-loading (55%, w/w) and undergo rapid and selective conversion into intact drug molecules in response to ROS; (II) a polyethylene glycol (PEG) shell to improve colloid stability and extend blood circulation, and (III) surface-modified internalizing RGD (iRGD) to increase tumor targeting. Enhancement of the antitumor effect of this delivery system was demonstrated against GC tumors in vitro and in vivo. This novel approach offers the potential for clinical applications of UA.The main culprit behind most cancers is the accumulation of reactive oxygen species. Glyoxal (GO) and methylglyoxal (MGO) are reactive intermediates created by food processing and they are precursors of advanced glycation end products (AGE) that cause glycative stress. We aimed to evaluate the relationship between AGE levels of healthy volunteers and treatment-naive patients diagnosed with colorectal cancer. The study consisted of patients diagnosed with colorectal cancer and healthy volunteers who underwent routine colonoscopy. The study was conducted with a total of 42 cases, 47.6% (n = 20) female. The ages of the participants in the study ranged from 41 to 82 years, and the mean was 60.57 ± 10.78 years. The GO and MGO values of the patient group were found to be significantly higher than those of the control group (p = 0.007, p = 0.001, respectively). The risk of colorectal cancer was 22 and 57 times higher in individuals with GO and MGO values above 1.25 μg/mL and 0.0095 μg/mL, respectively. The blood AGE level is closely related to diet, and it can be decreased through the appropriate improvement of diet. Thus, the measurement of AGE can be used to predict whether a person's nutrition is healthy or unhealthy and prevent increased risk of colorectal cancer.Quercetin-loaded nanosuspensions (Que-NSps) added metabolic inhibitors were evaluated as drug delivery system to promote the oral bioavailability of quercetin. Que-NSps were prepared respectively using d-alpha tocopherol acid polyethylene glycol succinate (TPGS) or Soybean Lecithin (SPC) as stabilizer. On the basis, Piperine (Pip) or sodium oleate (SO) was, respectively, encapsulated in Que-NSps as phase II metabolic inhibitors. The resulting Que-NSps all displayed a mean particle size of about 200 nm and drug loading content was in the range of 22.3-27.8%. The release of quercetin from Que-NSps was slow and sustained. After oral administration of 50 mg/kg different Que-NSps, the levels of free quercetin in plasma were significantly promoted, the concentration of quercetin metabolites (isorhamnetin and quercetin 3-O-β-d-Glucuronide) were decreased. The absolute bioavailability was, respectively 15.55%, 6.93%, 12.38%, and 23.58% for TPGS-Que-NSps, TPGS-SO-Que-NSps, SPC-Que-NSps, and SPC-Pip-Que-NSps, and 3.61% for quercetin water suspension. SPC-Pip-Que-NSps turned out to an ideal nanocarrier combined nano drug delivery system together with metabolic inhibitor to promote oral absorption of quercetin.Daratumumab, pomalidomide, and dexamethasone (DPd) is an FDA-approved 3rd or later line of therapy for myeloma. However, as there are limited published data on the efficacy of 2nd-line DPd, we conducted a retrospective analysis (n = 33). Herein, we report our center's data for 2nd-line DPd. Our patient population had a high amount of high risk cytogenetics (45.5%). The overall response rate (ORR) was 84.9% with a 1-year Progression Free Survival (PFS) of 37.7%. In standard risk myeloma (n = 18), the ORR was 88.9% and 1-year PFS was 61.1% (95% CI 42.3-88.3%). click here In high risk myeloma (45.5%, n = 15), the ORR was 80% with a 1-year PFS of 7.3% (95% CI 1.1-47.9%). This suggests that the efficacy of 2nd-line DPd in myeloma with high risk cytogenetics should be further investigated.Introduction Blood coagulation factor XII (FXII) is an emerging and potentially safe drug target, which dysregulation is associated with thrombosis, hereditary angioedema, and (neuro)inflammation. At the same time, FXII-deficiency is practically asymptomatic. Industrial and academic institutions have developed a number of potential therapeutic agents targeting either FXII zymogen or its active form FXIIa for the treatment of thrombotic and inflammatory conditions associated with the activity of this enzyme.Areas covered A short overview of the FXII(a) structure and function, underlining its suitability as a drug target, is given. The article reviews patents reported over the last three decades on FXII(a)-targeting therapeutic agents. These agents include small molecules, proteins, peptides, oligonucleotides, siRNAs, and monoclonal antibodies.Expert opinion The performed analysis of patents revealed that many FXII(a) inhibitors are in the early preclinical stage, while several already showed efficacy in vivo animal models of thrombosis, sepsis, hereditary angioedema, and multiple sclerosis. Two anti-FXIIa agents namely tick protein Ir-CPI and monoclonal antibody CSL312 are currently in human clinical trials. The results of these trials and further studies of FXII(a) pathophysiological functions will encourage the development of new FXII(a) inhibitors.Brain drug delivery remains a major difficulty for several challenges including the blood-brain barrier, lesion spot targeting, and stability during circulation. Blood cells including erythrocytes, platelets, and various subpopulations of leukocytes have distinct features such as long-circulation, natural targeting, and chemotaxis. The development of biomimetic drug delivery systems based on blood cells for brain drug delivery is growing fast by using living cells, membrane coating nanotechnology, or cell membrane-derived nanovesicles. Blood cell-based vehicles are superior delivery systems for their engineering feasibility and versatile delivery ability of chemicals, proteins, and all kinds of nanoparticles. Here, we focus on advances of blood cell-based biomimetic carriers for from blood to brain drug delivery and discuss their translational challenges in the future.
