Measuring induction period for calcium sulfate dihydrate precipitation

Homogeneous nucleation of CaSO{sub 4}{center_dot}2H{sub 2}O (gypsum) based on an optical diagnostic technique was studied within a supersaturation range of 1--4 at 25--90 C. The experiments were carried out using an experimental apparatus consisting of a batch crystallizer with the related measurement devices. Signals of scattered and transmitted light coming from a He-Ne laser source were analyzed to measure the induction period (t{sub ind}), that is, the time delay necessary for homogeneous nucleation to take place. As expected from theory, it was found that t{sub ind} decreases when either temperature or supersaturation increase; from the dependence of t{sub ind} on supersaturation, it was possible to distinguish between the mechanisms of homogeneous and heterogeneous nucleation. From the experimental data relative to homogeneous nucleation, the interfacial tension ({gamma}{sub s}) between CaSO{sub 4}{center_dot}2H{sub 2}O and the surrounding aqueous solution and the activation energy (E{sub att}) for CaSO{sub 4}{center_dot}2H{sub 2}O crystallization were evaluated. In particular, the dependence of t{sub ind} on temperature made it possible to evaluate E{sub att} at 30 kJ/mol and the dependence of t{sub ind} on supersaturation offered the value of {gamma}{sub s} to be about 37 mJ/m{sup 2}, which does not vary with temperature in the interval explored.
Regulation of the conserved 3′‐5′ exoribonuclease EXOSC10/Rrp6 during cell division, development and cancer

The conserved 3′‐5′ exoribonuclease EXOSC10/Rrp6 processes and degrades RNA, regulates gene expression and participates in DNA double‐strand break repair and control of telomere maintenance via degradation of the telomerase RNA component. EXOSC10/Rrp6 is part of the multimeric nuclear RNA exosome and interacts with numerous proteins. Previous clinical, genetic, biochemical and genomic studies revealed the protein's essential functions in cell division and differentiation, its RNA substrates and its relevance to autoimmune disorders and oncology. However, little is known about the regulatory mechanisms that control the transcription, translation and stability of EXOSC10/Rrp6 during cell growth, development and disease and how these mechanisms evolved from yeast to human. Herein, we provide an overview of the RNA‐ and protein expression profiles of EXOSC10/Rrp6 during cell division, development and nutritional stress, and we summarize interaction networks and post‐translational modifications across species. Additionally, we discuss how known and predicted protein interactions and post‐translational modifications influence the stability of EXOSC10/Rrp6. Finally, we explore the idea that different EXOSC10/Rrp6 alleles, which potentially alter cellular protein levels or affect protein function, might influence human development and disease progression. In this review we interpret information from the literature together with genomic data from knowledgebases to inspire future work on the regulation of this essential protein's stability in normal and malignant cells.
Benefit of a more extended pelvic lymph node dissection among patients undergoing radical prostatectomy for localized prostate cancer: A causal mediation analysis

The therapeutic role of extended (ePLND) versus nonextended pelvic lymph node dissection (nePLND) to remove occult micrometastases in men undergoing radical prostatectomy for localized prostate cancer (PC) is conflicting. Therefore, our aim was to quantify the direct effect of ePLND versus nePLND (removal of occult micrometastases), which is not mediated through the detection of nodal disease and potential adjuvant therapy (indirect effect).
Anthracycline-Induced Cardiotoxicity: The Role of Endothelial Dysfunction

Cardiovascular disease remains the leading cause of mortality accounting up to 40% of all deaths, but, currently, cancer is prominent cause of death globally. Anthracyclines are the cornerstone of chemotherapy in women with breast cancer. However, its clinical use is limited by their cardiotoxic effects that can trigger heart failure development. Vascular toxicity of chemotherapy may be linked with endothelial dysfunction because anthracycline damage of endothelial cells can lead to the development and progression of cardiomyopathy by decreasing the release and activity of endothelial factors and, ultimately, endothelial cell death. These processes suppress anti-inflammatory and vascular reparative functions and initiate the development of future cardiovascular events. Recent studies have shown that chemotherapy may induce toxicity in the vascular endothelium and is accompanied by systemic endothelial dysfunction in patients with diagnosed cardiovascular diseases. Because the initial endothelial cell insult is likely asymptomatic, there is often a long delay between the termination of doxorubicin therapy and the onset of vascular disorders. In this case, genetic susceptibility factor will help to identify susceptible patients in the future. The objectives of this study were to evaluate prognostic role of molecular (endothelin-1) and genetic factors (gene polymorphisms of endothelial nitric oxide (NO) synthase (NOS3, rs1799983), endothelin-1 receptor type A (EDNRA, C+70G, rs5335) and NADPH oxidase (C242T, rs4673) in development of endothelial dysfunction and anthracycline-induced cardiotoxicity in women without cardiovascular diseases.
An unusual ophthalmic presentation of Wolf-Hirschhorn syndrome

ABSTRACT Purpose: Wolf-Hirschhorn syndrome (WHS) is a rare inherited disease caused by the deletion in short arm of 4th chromosome. Various ocular manifestations in WHS have been described previously. We present an extraordinary clinical case of WHS associated with optic nerve head malformation and optic nerve sheath enlargement in the same eye. Methods: Case report Results: A male infant was delivered by Caesarean section at 38 weeks with a birth weight of 2040 gr and admitted to neonatal intensive care unit due to multi-systemic abnormalities. The infant had multiple congenital anomalies; a cleft palate, microcephalia, micrognathia, renal pelvicalyceal ectasia, atrial septal defect, transvers arcus hypoplasia, patent ductus arteriosus, hypospadias and undescended testicle. Fundus examination revealed optic disc coloboma of both eyes. Two weeks later, at the second examination, the left optic disc margins were indistinct with vessels radiating from the disc margins which resembles morning glory disc anomaly (MGDA). The MRI demonstrated corpus callosum agenesis and a T1 hypointense, T2 hyperintense, 12 × 9 mm optic nerve sheath enlargement in the retrobulbar area. Conclusion: The case presented here demonstrates that, the optic nerve head malformations and optic nerve sheath enlargement may be due to incomplete closure of choroidal fissure and subsequent accumulation of cerebrospinal fluid may result in a spectrum of optic nerve head malformations.

Vitamin C Is an Ideal Substitute for Hydrazine in the Reduction of Graphene Oxide Suspensions

The preparation of solution-processable graphene from graphite oxide typically involves a hydrazine reduction step, but the use of such a reagent in the large-scale implementation of this approach is not desirable due to its high toxicity. Here, we compare the deoxygenation efficiency of graphene oxide suspensions by different reductants (sodium borohydride, pyrogallol, and vitamin C, in addition to hydrazine), as well as by heating the suspensions under alkaline conditions. In almost all cases, the degree of reduction attainable and the subsequent restoration of relevant properties (e.g., electrical conductivity) lag significantly behind those achieved with hydrazine. Only vitamin C is found to yield highly reduced suspensions in a way comparable to those provided by hydrazine. Stable suspensions of vitamin C-reduced graphene oxide can be prepared not only in water but also in common organic solvents, such as N,N-dimethylformamide (DMF) or N-methyl-2-pyrrolidone (NMP). These results open the perspective .
Iron, coronary artery calcification, and mortality in patients undergoing hemodialysis

Abstract Objective A high coronary artery calcification score (CACS) may be associated with high mortality in patients undergoing hemodialysis (HD). Recently, effects of iron on vascular smooth muscle cell calcification have been described. We aimed to investigate the relationships between iron, CACS, and mortality in HD patients. Methods We studied 173 consecutive patients who were undergoing maintenance HD. Laboratory data and Agatston’s CACS were obtained at baseline for two groups of patients: those with CACS ≥400 (n = 109) and those with CACS <400 (n = 64). Logistic regression analyses for CACS ≥400 and Cox proportional hazard analyses for mortality were conducted. Results The median (interquartile range) age and duration of dialysis of the participants were 67 (60–75) years and 73 (37–138) months, respectively. Serum iron (Fe) and transferrin saturation (TSAT) levels were significantly lower in participants with CACS ≥400 than in those with CACS <400, although the serum ferritin concentration did not differ between the groups. TSAT ≥21% was significantly associated with CACS ≥400 (odds ratio 0.46, p<0.05). TSAT ≥17%, Fe ≥63 µg/dL, and ferritin ≥200 ng/mL appear to protect against 5-year all-cause mortality in HD patients, independent of conventional risk factors of all-cause mortality (p < 0.05). Conclusion We have identified associations between iron, CACS, and mortality in HD patients. Lower TSAT was found to be an independent predictor of CACS ≥400, and iron deficiency (low TSAT, iron, or ferritin) was a significant predictor of 5-year all-cause mortality in HD patients.
Modulation of the Canonical Wnt Signaling Pathway by Dietary Polyphenols, an Opportunity for Colorectal Cancer Chemoprevention and Treatment

Abstract In the last few decades there has been a rise in the worldwide incidence of colorectal cancer which can be traced back to the influence of well-known modifiable risk factors such as lifestyle, diet and obesity. Conversely, the consumption of fruits, vegetables and fiber decreases the risk of CRC, which is why dietary polyphenols have aroused interest in recent years as potentially anti-carcinogenic compounds. One of the driving forces of colorectal carcinogenesis, in both sporadic and hereditary CRC, is the aberrant activation/regulation of the Wnt/β-catenin pathway. This review discusses reports of modulation of the Wnt/β-Catenin signaling pathway by dietary polyphenols (resveratrol, avenanthramides, epigallocatechinin, curcumin, quercetin, silibinin, genistein and mangiferin) specifically focusing on CRC, and proposes a model as to how this modulation occurs. There is potential for implementing these dietary polyphenols into preventative and therapeutic therapies for CRC as evidenced by some clinical trials that have been carried out with promising results.
Magnetic field and surface influences on double injection phenomena in semiconductors. I. The magnetodiode effect theory for the semiconductor and insulator regimes

The general context of the magnetodiode effect is analysed according to an original theory. This effect is the superposition of the magnetoconcentration effect and of double injection phenomena: the electrons and holes injected by the end contacts are submitted to a magnetic deflection towards the same surface of the semiconductor, where the recombination process is responsible for the carrier density modulation; the resulting transverse carrier gradient directly influences the current magnitude. The behaviour of semiconductor plates provided with one or two injecting contacts is studied with the same twodimensional formalism. The successive steady-state reg imesof the magnetodiode teffect are analysed for various parameters: external fields, bulk and surface recombination mechanisms, doping, and dimensions. It is shown that the classical current—voltage laws of the semiconductor and insulator regimes are subjected to considerable qualitative and quantitative modifications owing to both, the Lorentz forces and the recombination velocities. These parameters can be included in a carrier effective lifetime, the value of which is governed, for low inductions, by the longitudinal drift current and, for high inductions, by the transverse diffusion current. One of the main motivations of this work is to show that the p+nn+ magnetodiodes are ultrasensitive devices; hen the appropriate conditions allowing their optimum operating will be carefully defined. Nous proposons une theorie generale de l'effet magnetodiode, qui represente la superposition de l'effet de magnetoconcentration aux phenomenes de double injection: lee electrons et les trous injectes par les contacts sont soumis e une deflection magnetique vers la měme surface du semiconducteur, ou le taux d'accumulation depend des processus de recombinaison; le gradient transversal de porteurs qui en resulte agit fortement sur la conduction electrique. Un formalisme bidimensionnel nous permet de decrire le comportement des structures a un ou deux contacts injectants. Les differents reimes permanents de l'effet magnetodiode sont analyses pour plusieurs parametres: champs exterieurs, recombinaisons en volume et sur les surfaces, dopage et dimensions. Nous montrons que les lois courant-tension classiques des regimes semiconducteur et isolant sont notablement modifiees par les forces de Lorentz et par les vitesses de recombinaison. Ces parametres sont inch dans une duree de vie effective des porhurs, dont la valeur est gouvernee, a faible induction magnetique, par les courants longitudinaux de derive et, a forte induction, par les courants transversaux de diffusion. Ce travail etant egalement motive par les tres hautes sensibilites des magnetodiodes p+nn+, nous definirons soigneusement les conditions optimales de fonctionnement.
Standalone iStent Trabecular Micro-bypass Glaucoma Surgery: A Systematic Review and Meta-Analysis

Precis: Standalone trabecular micro-bypass glaucoma surgery with the iStent devices is associated with clinically relevant reductions in intraocular pressure (IOP) sustained over a reasonably long-term while simultaneously reducing medication burden and a relatively favorable safety profile. Purpose: While there is a relatively large body of evidence supporting the implantation of the iStent trabecular micro-bypass devices during phacoemulsification in patients with open-angle glaucoma (OAG), its efficacy as a standalone procedure has been less widely reported. The aims of this study were to systematically identify and quantitatively evaluate the efficacy of iStent devices (iStent and iStent inject) when performed independently of cataract surgery in patients with OAG. Methods: A systematic review of the literature was undertaken in August 2019 to identify studies of standalone trabecular micro-bypass glaucoma surgery with iStent devices in patients with OAG. All randomized trials were considered and nonrandomized studies that included at least 6 months of follow-up or more than 10 eyes. Key efficacy analyses included postoperative IOP and medication use, which were used to evaluate weighted mean differences from baseline, and the proportion of eyes free of ocular medication. Postoperative adverse events were descriptively summarized. Results: A total of 13 studies were identified including 4 randomized controlled trials and 9 nonrandomized or single-arm studies providing data for 778 eyes. In eyes implanted with iStent devices, a weighted mean IOP reduction of 31.1% was observed at 6 to 12 months. In studies reporting longer-term outcomes (36 to 48 mo or 60 mo), the weighted mean IOP reduction was 30.4% and 32.9%, respectively. The pooled weighted mean reduction in IOP from baseline across all studies at 6 to 12 months and 36 to 60 months poststent implantation was 7.01 mm Hg (95% confidence interval: 5.91, 8.11) and 6.59 mm Hg (95% confidence interval: 5.55, 7.63), respectively. Medication burden was reduced by ~1.0 medication at 6 to 18 months and 1.2 medications at 36 to 60 months. Adverse events reported in more than 5% of participants were progression of pre-existing cataract/cataract surgery and loss of best-corrected visual acuity but these rates were no different to those reported in comparator medical therapy study arms. Conclusions: The results from these studies support the independent effect of the iStent trabecular bypass devices on IOP and medication burden over a duration of follow-up of up to 5 years.
Inhibition of ATM Induces Hypersensitivity to Proton Irradiation by Upregulating Toxic End Joining

Coadministration of an ATM inhibitor rewires DNA repair machinery to render cancer cells uniquely hypersensitive to DNA damage induced by the proton Bragg peak, which is characterized by higher density ionization. Proton Bragg peak irradiation has a higher ionizing density than conventional photon irradiation or the entrance of the proton beam profile. Whether targeting the DNA damage response (DDR) could enhance vulnerability to the distinct pattern of damage induced by proton Bragg peak irradiation is currently unknown. Here, we performed genetic or pharmacologic manipulation of key DDR elements and evaluated DNA damage signaling, DNA repair, and tumor control in cell lines and xenografts treated with the same physical dose across a radiotherapy linear energy transfer spectrum. Radiotherapy consisted of 6 MV photons and the entrance beam or Bragg peak of a 76.8 MeV spot scanning proton beam. More complex DNA double-strand breaks (DSB) induced by Bragg peak proton irradiation preferentially underwent resection and engaged homologous recombination (HR) machinery. Unexpectedly, the ataxia-telangiectasia mutated (ATM) inhibitor, AZD0156, but not an inhibitor of ATM and Rad3-related, rendered cells hypersensitive to more densely ionizing proton Bragg peak irradiation. ATM inhibition blocked resection and shunted more DSBs to processing by toxic ligation through nonhomologous end-joining, whereas loss of DNA ligation via XRCC4 or Lig4 knockdown rescued resection and abolished the enhanced Bragg peak cell killing. Proton Bragg peak monotherapy selectively sensitized cell lines and tumor xenografts with inherent HR defects, and the repair defect induced by ATM inhibitor coadministration showed enhanced efficacy in HR-proficient models. In summary, inherent defects in HR or administration of an ATM inhibitor in HR-proficient tumors selectively enhances the relative biological effectiveness of proton Bragg peak irradiation. Significance: Coadministration of an ATM inhibitor rewires DNA repair machinery to render cancer cells uniquely hypersensitive to DNA damage induced by the proton Bragg peak, which is characterized by higher density ionization.

The analysis on the human protein domain targets and host-like interacting motifs for the MERS-CoV and SARS-CoV/CoV-2 infers the molecular mimicry of coronavirus

The MERS-CoV, SARS-CoV, and SARS-CoV-2 are highly pathogenic viruses that can cause severe pneumonic diseases in humans. Unfortunately, there is a non-available effective treatment to combat these viruses. Domain-motif interactions (DMIs) are an essential means by which viruses mimic and hijack the biological processes of host cells. To disentangle how viruses achieve this process can help to develop new rational therapies. Data mining was performed to obtain DMIs stored as regular expressions (regexp) in 3DID and ELM databases. The mined regexp information was mapped on the coronaviruses’ proteomes. Most motifs on viral protein that could interact with human proteins are shared across the coronavirus species, indicating that molecular mimicry is a common strategy for coronavirus infection. Enrichment ontology analysis for protein domains showed a shared biological process and molecular function terms related to carbon source utilization and potassium channel regulation. Some of the mapped motifs were nested on B, and T cell epitopes, suggesting that it could be as an alternative way for reverse vaccinology. The information obtained in this study could be used for further theoretic and experimental explorations on coronavirus infection mechanism and development of medicines for treatment.
Joint Statement (DZK, DGRh, DDG) on the Tuberculosis Risk with Treatment Using Novel Non-TNF-Alpha Biologicals

Abstract Background While the risk of tuberculosis (TB) reactivation is adequately documented in relation to TNF-alpha inhibitors (TNFi), the question of what the tuberculosis risk is for newer, non-TNF biologics (non-TNFi) has not been thoroughly addressed. Methods We conducted a systematic review of randomized phase 2 and phase 3 studies, and long-term extensions of same, published through March 2019. Of interest was information pertaining to screening and treating of latent tuberculosis (LTBI) in association with the use of 12 particular non-TNFi. Only rituximab was excluded. We searched MEDLINE and the ClinicalTrial.gov database for any and all candidate studies meeting these criteria. Results 677 citations were retrieved; 127 studies comprising a total of 34,293 patients who received non-TNFi were eligible for evaluation. Only 80 out of the 127 studies, or 63 %, captured active TB (or at least opportunistic diseases) as potential outcomes and 25 TB cases were reported. More than two thirds of publications (86/127, 68 %) mentioned LTBI screening prior to inclusion of study participants in the respective trial, whereas in only 4 studies LTBI screening was explicitly considered redundant. In 21 studies, patients with LTBI were generally excluded from the trials and in 42 out of the 127 trials, or 33 %, latently infected patients were reported to receive preventive therapy (PT) at least 3 weeks prior to non-TNFi treatment. Conclusions The lack of information in many non-TNFi studies on the number of patients with LTBI who were either excluded prior to participating or had been offered PT hampers assessment of the actual TB risk when applying the novel biologics. Therefore, in case of insufficient information about drugs or drug classes, the existing recommendations of the German Central Committee against Tuberculosis should be applied in the same way as is done prior to administering TNFi. Well designed, long-term “real world” register studies on TB progression risk in relation to individual substances for IGRA-positive cases without prior or concomitant PT may help to reduce selection bias and to achieve valid conclusions in the future.
