ABSTRACT

The use of copper-based artificial nucleases as potential anticancer agents has been hampered by their poor selectivity in the oxidative DNA cleavage process. An alternative strategy to solve this problem is to design systems capable of selectively damaging noncanonical DNA structures that play crucial roles in the cell cycle. We designed an oligocationic CuII peptide helicate that selectively binds and cleaves DNA three-way junctions (3WJs) and induces oxidative DNA damage via a ROS-mediated pathway both in vitro and in cellulo, specifically at DNA replication foci of the cell nucleus, where this DNA structure is transiently generated. To our knowledge, this is the first example of a targeted chemical nuclease that can discriminate with high selectivity 3WJs from other forms of DNA both in vitro and in mammalian cells. Since the DNA replication process is deregulated in cancer cells, this approach may pave the way for the development of a new class of anticancer agents based on copper-based artificial nucleases.

ABSTRACT

The development of compounds that can selectively bind with non-canonical DNA structures has expanded in recent years. Junction DNA, including three-way junctions (3WJs) and four-way Holliday junctions (HJs), offer an intriguing target for developmental therapeutics as both 3WJs and HJs are involved in DNA replication and repair processes. However, there are a limited number of assays available for the analysis of junction DNA binding. Here, we describe the design and execution of multiplex fluorescent polyacrylamide gel electrophoresis (PAGE) and microscale thermophoresis (MST) assays that enable evaluation of junction-binding compounds. Two well characterised junction-binding compounds-a C6 linked bis-acridine ligand and an iron(II)-bound peptide helicate, which recognise HJs and 3WJs, respectively-were employed as probes for both MST and PAGE experiments. The multiplex PAGE assay expands beyond previously reported fluorescent PAGE as it uses four individual fluorophores that can be combined to visualise single-strands, pseudo-duplexes, and junction DNA present during 3WJ and HJ formation. The use of MST to identify the binding affinity of junction binding agents is, to our knowledge, first reported example of this technique. The combined use of PAGE and MST provides complementary results for the visualisation of 3WJ and HJ formation and the direct binding affinity (Kd and EC50) of these agents. These assays can be used to aid the discovery and design of new therapeutics targeting non-canonical nucleic acid structures.

ABSTRACT

PURPOSE: To discuss diagnosis and management in the case of a patient presenting with bilateral ischemic retinal vasculopathy associated with a previously undiagnosed IgA nephropathy. CASE REPORT: In 2021, a 35-year-old male presented with a sudden onset asymmetric bilateral (OU) visual loss. Best-corrected visual acuity (BCVA) was 20/200 OD, and no light perception (NLP) OS with an associated relative afferent pupillary defect (RAPD). Slit-lamp examination (SLE) confirmed normal anterior segment anatomy OU. Indirect ophthalmoscopy and subsequent fluorescein angiography (FA) confirmed the presence of bilateral arterial attenuation, telangiectatic lesions, associated perivascular sheathing, and capillary leakage. Spectral domain optical coherence tomography (OCT) showed multiple areas of thinning of the inner retina. This constellation of diagnostic findings was highly suggestive of a bilateral ischemic retinal vasculopathy with an inflammatory vasculitis. Based on a high index of suspicion for a systemic etiology, nephrology was consulted, and a diagnosis of IgA nephropathy was confirmed by renal biopsy. Systemic immunomodulatory therapy was initiated. CONCLUSION: Although it is among the most commonly occurring forms of glomerulonephritis leading to renal failure, IgA nephropathy rarely presents with a bilateral retinal vasculopathy. Schölein - Henoch purpura, the other primary disease associated with glomerular IgA deposition, may be indistinguishable from primary IgA nephropathy. A comprehensive retinal examination with multimodal functional and structural ophthalmic diagnostic testing in conjunction with renal biopsy was needed to confirm the diagnosis. It is critical to include primary renal pathology when formulating a differential diagnosis for cases of bilateral retinal vasculitis, particularly in young otherwise healthy patients.

ABSTRACT

RESUMEN Introducción: La reestenosis de los stents liberadores de paclitaxel utilizados en Cuba no ha sido estudiada. Objetivo: Evaluar la reestenosis de los stents liberadores de paclitaxel y los convencionales. Métodos: Se incluyeron 64 pacientes con reestenosis de stent, de un estudio prospectivo previo; en 318 pacientes seguidos por 3 años luego de intervención coronaria percutánea; 25 con stent liberador de paclitaxel y 39 stent metálico convencional. Se consideró reestenosis como nueva lesión ≥ 50 % de la luz del vaso con isquemia demostrada. Se describió el tiempo de aparición, patrón angiográfico y alternativa de revascularización. Resultados: La reestenosis en el grupo de stents liberadores de paclitaxel fue 15,7 % con tiempo medio de supervivencia sin reestenosis de 32,4 meses vs. 24,5 % en stents convencionales, con supervivencia sin reestenosis de 29,8 meses, (p= 0,047). En el grupo de stents liberadores de paclitaxel predominó el patrón IB, (30,3 %) y stent convencional el III (28,3 %). En el 28,0 % del grupo de stents liberadores de paclitaxel, se recurrió a la cirugía de revascularización vs. 5,1 % en el grupo de stent convencional. Conclusiones: El stent liberador de paclitaxel logra una supervivencia libre de reestenosis superior y más perdurable que el stent convencional. La reestenosis en los de stents liberadores de paclitaxel es focal, con mayor frecuencia de nueva revascularización por cirugía y en los stents convencionales es mayormente difusa.


ABSTRACT Introduction: The restenosis of the paclitaxel-eluting stents used in Cuba has not been studied. Objective: To evaluate the restenosis of paclitaxel-eluting stents and conventional stents. Methods: 64 patients with stent restenosis were included, from a previous prospective study; in 318 patients followed up for 3 years after percutaneous coronary intervention; 25 with a paclitaxel-eluting stent and 39 conventional metal stent. Restenosis was considered as a new lesion ≥ 50 % of the vessel lumen with proven ischemia. The time to onset, angiographic pattern and alternative revascularization were described. Results: Restenosis in the group with paclitaxel-eluting stents was 15.7 % with a mean survival time without restenosis of 32.4 months vs. 24.5 % in conventional stents, with restenosis-free survival of 29.8 months, (p = 0.047). In the group with paclitaxel-eluting stents, the IB pattern predominated (30.3 %) and the conventional stent III (28.3 %). In 28.0 % of the paclitaxel-eluting stent group, revascularization surgery was used vs. 5.1 % in the conventional stent group. Conclusions: The paclitaxel-eluting stent achieves a superior and more durable restenosis-free survival than the conventional stent. Restenosis in paclitaxel-eluting stents is focal, with a higher frequency of revascularization by surgery, and in conventional stents it is mostly diffuse.

ABSTRACT

Here we have employed SynCon(R) design technology to construct a DNA vaccine expressing a pan-Spike immunogen (INO-4802) to induce broad immunity across SARS-CoV-2 variants of concern (VOC). Compared to WT and VOC-matched vaccines which showed reduced cross-neutralizing activity, INO-4802 induced potent neutralizing antibodies and T cell responses against WT as well as B.1.1.7, P.1, and B.1.351 VOCs in a murine model. In addition, a hamster challenge model demonstrated that INO-4802 conferred superior protection following intranasal B.1.351 challenge. Protection against weight loss associated with WT, B.1.1.7, P.1 and B.1.617.2 challenge was also demonstrated. Vaccinated hamsters showed enhanced humoral responses against VOC in a heterologous WT vaccine prime and INO-4802 boost setting. These results demonstrate the potential of the pan-SARS-CoV-2 vaccine, INO-4802 to induce cross-reactive immune responses against emerging VOC as either a standalone vaccine, or as a potential boost for individuals previously immunized with WT-matched vaccines.

ABSTRACT

OBJECTIVE: To evaluate the impact of a cervical cancer (CC) diagnosis on use of health care and prescription drugs. METHODS: This population-based register-study included Danish women aged 23-59 years and diagnosed with CC in 2001-2005. Women with a cervical screening outcome were used as comparison group. We obtained number of contacts to general practitioners (GPs), hospitals, psychologists/psychiatrists and defined daily doses (DDD) of analgesic/psychotropic prescription drugs. A difference-in-differences-design was used to estimate effect of a CC diagnosis on health-care use from five-year periods before and after the diagnosis/screening outcome. RESULTS: In total, 926 women with CC and 1,004,759 women without cancer were included. In five years following the date of CC diagnosis, CC patients had increased their use of GPs with 8.6 (95% CI 4.8-12.4) contacts more than women in the comparison group, and with 4.12 (95% CI 3.99-4.25) more hospital contacts. In contrast, use of psychologists/psychiatrists was low and largely unaffected by the CC diagnosis. For use of prescription drugs, analgesics increased with 80 (95% CI 60-100) DDD more in CC patients than in comparison women, and for psychotropics with 304 (95% CI 261-347) DDD more. CONCLUSIONS: A CC diagnosis was followed by an increase in use of GPs, hospitals, and analgesic/psychotropic prescription drugs, while use of psychologist/psychiatrist was largely unaffected. This pattern may indicate that pain/mental health concerns after CC either persisted or were alleviated by other means only.

ABSTRACT

We propose a new analytical method for determining the response threshold in electroretinogram (ERG) in which the wave shows a biphasic slow dc-potential shift. This method uses the recorded wave to the highest intensity stimuli in each wavelength tested as a template wave f(t), and it was compared with other recorded waves obtained under lower intensities g(t). Our test recordings in medaka Oryzias latipes were analogous between the template and the compared waveforms, although there were differences in amplitude and time lag (τ, peak time difference) which occurred as a result of the difference in stimulus intensity. Cross-correlation analysis was applied. Based on the obtained cross-correlation function Cfg(τ) in each comparison, τ was determined as the time lag at which the cross-correlation coefficient Rfg(τ) showed the maximum value. Determined thresholds that were based on both the experimenter's visual inspection and this new method agreed well when the adoption condition was set to satisfy R(τ) ≥ 0.7 and τ ≤ 150 ms in scotopic or τ ≤ 120 ms in photopic conditions. We concluded that this "template wave matching method" is a quick and reliable objective assessment that can be used to determine the threshold. This study analyzed ERG recordings in response to 6 kinds of wavelength light stimuli (380 nm to 620 nm) at different photon flux densities. We report the threshold levels and relative spectral sensitivities in scotopic and photopic vision of medaka.

ABSTRACT

We describe a large-scale community effort to build an open-access, interoperable, and computable repository of COVID-19 molecular mechanisms - the COVID-19 Disease Map. We discuss the tools, platforms, and guidelines necessary for the distributed development of its contents by a multi-faceted community of biocurators, domain experts, bioinformaticians, and computational biologists. We highlight the role of relevant databases and text mining approaches in enrichment and validation of the curated mechanisms. We describe the contents of the Map and their relevance to the molecular pathophysiology of COVID-19 and the analytical and computational modelling approaches that can be applied for mechanistic data interpretation and predictions. We conclude by demonstrating concrete applications of our work through several use cases and highlight new testable hypotheses.

ABSTRACT

We report the first Ru(ii) coordination compounds that interact with DNA through a canonical minor groove insertion mode and with selectivity for A/T rich sites. This was made possible by integrating a bis-benzamidine minor groove DNA-binding agent with a ruthenium(ii) complex. Importantly, one of the enantiomers (Δ-[Ru(bpy)2 b4bpy]2+, Δ-4Ru) shows a considerably higher DNA affinity than the parent organic ligand and the other enantiomer, particularly for the AATT sequence, while the other enantiomer preferentially targets long AAATTT sites with overall lower affinity. Finally, we demonstrate that the photophysical properties of these new binders can be exploited for DNA cleavage using visible light.

ABSTRACT

OBJECTIVE: This study aimed to assess the long-term use of health care services in women with abnormal cytology results compared to women with normal cytology results. METHODS: We did a nationwide population-based study, using women aged 23 to 59years participating in the national organized cervical cancer screening program. We included a study population of 40,153 women with abnormal cytology (exposed) and 752,627 women with normal cytology (non-exposed). We retrieved data from the Danish Civil Registration System, the Danish Pathology Data Bank, the National Health Service, the National Patient and the National Prescription Register. We calculated the frequencies of contacts to general practitioner (GP), to private psychiatrist and/or psychologist, admissions to hospitals and use of prescription drugs. These frequencies were calculated separately in the 5-year period "before" the cytology result and for the 5-year period "after" the result. RESULTS: During the "before" period exposed women had more contacts to GPs, more contacts to psychologists/psychiatrist, and more hospital admissions than non-exposed women. In both exposed and non-exposed women, health care use increased from the "before" to the "after" period. This increase was significantly higher for exposed than non-exposed women regarding contacts to GP, admissions to hospitals, and drug use. CONCLUSION: Women with abnormal cytology results constitute a selected group with a higher health care use than other women even before they have the abnormal cytology. This difference is further enhanced after the abnormal cytology result.

ABSTRACT

Cervical screening has been one of the most successful public health prevention programmes. For 50 years, cytology formed the basis for screening, and detected cervical intraepithelial lesions (CIN) were treated surgically to prevent progression to cancer. In a high-risk country as Denmark, screening decreased the incidence of cervical cancer from 34 to 11 per 100,000, age-standardized rate (World Standard Population). Screening is, however, also expensive; Denmark (population: 5.6 million) undertakes close to half a million tests per year, and has 6-8 CIN-treated women for each prevented cancer case. The discovery of human papillomavirus (HPV) as the cause of cervical cancer dramatically changed perspectives for disease control. Screening with HPV testing was launched around 1990, and preventive HPV vaccination was licensed in 2006. Long-term randomized controlled trials (RCT) demonstrated that HPV testing provides better protection against cervical cancer than cytology, but it requires extra repeated testing. HPV vaccination RCTs, furthermore, have proved that HPV vaccination protects against vaccine-type high-grade CIN in women vaccinated prior to sexual activity, but less so in women vaccinated later. The challenge now is therefore to find an algorithm for screening of a heterogeneous population including non-vaccinated women; women vaccinated prior to start of sexual activity; and women vaccinated later.

ABSTRACT

Two new sulfonamide-type fluorescent chemosensors in organic media are reported. The two receptors, [N,N'-bis(2-tosylaminobenzylidene)-1,2-diaminoethane and N,N'-bis(2-tosylaminobenzylidene)-1,3-diamino-2-propanol], display marked changes in the fluorescence emission intensities as a result of deprotonation by basic anions, and show high selectivity for fluoride over other inorganic anions, such as acetate or dihydrogenphosphate. These results suggest that the presence of the imine group as an intramolecular H-bond acceptor enhances the selectivity of these sensors compared to previous examples in the literature. The deprotonation mechanism has been demonstrated by spectrophotometric and spectrofluorimetric titrations as well as by NMR spectroscopy. The X-ray structures of both receptors are also discussed.

ABSTRACT

The Law to Promote Personal Autonomy and Care for people dependent on continual at home treatment has had strong repercussions not only in social relationships but in scientific health forums as well. At present time, what most concerns professionals and society at large is the development of a system which includes resources and services capable to ensure treatment to those who must continually depend on someone else for their basic care-needs. But, what is happening with our health care? In this review article, the authors propose to analyze health system coverage for those who depend on others for their continuous basic care-needs in our country.

ABSTRACT

Una persona con obesidad mórbida (cuyo ÍMC es superior al 40),tiene un mayor riesgo de padecer diversas enfermedades: hipertensiónarterial, diabetes, dificultad respiratoria, etc. La intervenciónbariátrica es una intervención quirúrgica complicada, en laque se requiere una actuación multidisciplinar durante todo suproceso (cirujano, anestesiólogo, enfermera, etc.).Este trabajo expone los cuidados enfermeros en este tipo de cirugíapara evitar complicaciones potenciales. Dichos cuidados seadaptarán individualmente a cada paciente, ya que las complicacionesvariarán en función de su estado de salud general previo ala intervención, del tipo de técnica quirúrgica utilizada así como dela evolución del postoperatorio inmediato


An individual with morbid obesity and a BMI over 40 has a higherrisk of suffering from several diseases: high blood pressure, diabetes,breathing difficulty, etc. Bariatric surgery is a complex surgicalprocedure requiring a multidisciplinary action during the entireprocess (surgeon, anaesthesiologists, nurse, etc.).This article describes the nursing care required in this type ofsurgery to avoid potential complications.
