A Copper-Binding Peptide with Therapeutic Potential against Alzheimer's Disease: From the Blood-Brain Barrier to Metal Competition.

Alzheimer's disease (AD) is the most common form of dementia worldwide. AD brains are characterized by the accumulation of amyloid-β peptides (Aβ) that bind Cu and have been associated with several neurotoxic mechanisms. Although the use of copper chelators to prevent the formation of Cu-Aβ complexes has been proposed as a therapeutic strategy, recent studies show that copper is an important neuromodulator that is essential for a neuroprotective mechanism mediated by Cu binding to the cellular prion protein (PrP).

Haematopoietic gene therapy of non-conditioned patients with Fanconi anaemia-A: results from open-label phase 1/2 (FANCOLEN-1) and long-term clinical trials.

Background: Allogeneic haematopoietic stem-cell transplantation is the standard treatment for bone marrow failure (BMF) in patients with Fanconi anaemia, but transplantation-associated complications such as an increased incidence of subsequent cancer are frequent. The aim of this study was to evaluate the safety and efficacy of the infusion of autologous gene-corrected haematopoietic stem cells as an alternative therapy for these patients.

Methods: This was an open-label, investigator-initiated phase 1/2 clinical trial (FANCOLEN-1) and long-term follow-up trial (up to 7 years post-treatment) in Spain.

Analysis of the heterologous expression, localization, and cellular response to the Zika virus E protein in vitro.

Zika virus (ZIKV) infection has been associated with damage to neural stem cells in microcephaly in newborns. The virus possesses specific tropism for glioma stem cells mediated by the ZIKV E protein. This infection causes endoplasmic reticulum stress and activation of the unfolded protein response (UPR).

Undifferentiated sarcoma arising from fibrous dysplasia in a young adult.

Fibrous dysplasia (FD) is a skeletal disorder characterized by the replacement of normal bone by fibrous tissue. Malignant transformation of FD is extremely rare and has been reported in both monostotic and polyostotic forms of FD. The most frequently reported malignant transformation is osteosarcoma.

European Society for Organ Transplantation (ESOT) Consensus Statement on the Use of Non-invasive Biomarkers for Cardiothoracic Transplant Rejection Surveillance.

While allograft rejection (AR) continues to threaten the success of cardiothoracic transplantation, lack of accurate and repeatable surveillance tools to diagnose AR is a major unmet need in the clinical management of cardiothoracic transplant recipients. Endomyocardial biopsy (EMB) and transbronchial biopsy (TBBx) have been the cornerstone of rejection monitoring since the field's incipience, but both suffer from significant limitations, including poor concordance of biopsy interpretation among pathologists. In recent years, novel molecular tools for AR monitoring have emerged and their performance characteristics have been evaluated in multiple studies.

Effect of virgin olive oil as spreadable preparation on atherosclerosis compared to dairy butter in Apoe-deficient mice.

Unlabelled: Olive oil is the main source of lipid energy in the Mediterranean diet and there is strong evidence of its health benefits. The effect of extra virgin olive oil (EVOO) in the form of a preparation of spreadable virgin olive oil (S-VO) on the progression of atheroma plaques was investigated in Apoe-deficient mice, a model of accelerated atherosclerosis.

Methods: Two isocaloric Western purified diets containing 20% fat, either as S-VO or as dairy butter, were used to feed 28 males and 16 females of two-month-old Apoe-deficient mice for 12 weeks.

The study employs Anderson's Behavioral Model of Healthcare Utilization Model to guide the exploration of alcohol use, help-seeking and healthcare utilization.

Methods: The present qualitative study explored help-seeking and alcohol treatment utilization for Hispanic men of Mexican ethnicity.

Restored glyoxylate metabolism after AGXT gene correction and direct reprogramming of primary hyperoxaluria type 1 fibroblasts.

Primary hyperoxaluria type 1 (PH1) is a rare inherited metabolic disorder characterized by oxalate overproduction in the liver, resulting in renal damage. It is caused by mutations in the gene. Combined liver and kidney transplantation is currently the only permanent curative treatment.

Successful long-term management of metastatic clear cell renal cell carcinoma with nivolumab: a case report and literature review.

In Colombia, renal cancer is a rare condition, with clear cell renal cell carcinoma (ccRCC) being the most prevalent neoplasm. In recent years, immune checkpoint inhibitors (ICI) have been proposed for the management of metastatic disease, as they have shown improved rates of response and long-term survival. Furthermore, they exhibit a favourable tolerance profile, and adverse events causing significant morbidity are infrequent.

Modulation of DR Splicing, Signaling, and Expression by DR through PKA→PTB Phosphorylation.

The DR and DR receptors functionally and synergistically interact in striatonigral neurons. Dopaminergic denervation turns this interaction antagonistic, which is correlated with a decrement in Dnf isoform and an increment in DR membranal expression. The mechanisms of such changes in DR are attributed to the dysregulation of the expression of their isoforms.

Traction images heavily influence lateral wall measurement in trochanteric hip fractures. A prospective study.

Introduction: hip fracture represents a global health problem, with a high morbidity and mortality rate and an increasing incidence. The treatment of trochanteric fractures is reduction and osteosynthesis, and implant selection depends mainly on the stability of the fracture and lateral wall competence. Lateral wall competence has gained relevance in recent years, which led to the modification of the AO/OTA classification.

Multidisciplinary approach to patients with heart failure and kidney disease: preliminary experience of an integrated cardiorenal unit.

Background: Cardiorenal programs have emerged to improve the management of cardiorenal disease (CRD). Evidence about the benefits of these programs is still scarce. This work aims to evaluate the performance of a novel cardiorenal program and describe the clinical profile and outcomes of patients with CRD.

A human genome editing-based MLL::AF4 ALL model recapitulates key cellular and molecular leukemogenic features.

Cellular ontogeny and MLL breakpoint site influence the capacity of MLL-edited CD34+ hematopoietic cells to initiate and recapitulate infant patients' features in pro-B-cell acute lymphoblastic leukemia (B-ALL). We provide key insights into the leukemogenic determinants of MLL-AF4+ infant B-ALL.

Por los Niños: Latine Caregivers' Reflections on Parenting in the Context of Immigration.

Immigrant families face unique challenges, most notably the active negotiation of two cultures not only at the individual level, but also in the context of family relationships. There is limited research exploring how immigrant caregivers of young children, in particular, experience this cultural negotiation in the context of parenting decisions and practices as these relate to their children's development and schooling. The current study sought to understand immigrant parenting from a phenomenological, emic ("inside-out") perspective (Hall et al.

Amazonian medicinal plants efficiently inactivate Herpes and Chikungunya viruses.

The Amazonian species investigated in this research are commonly utilized for their anti-inflammatory properties and their potential against various diseases. However, there is a lack of scientifically supported information validating their biological activities. In this study, a total of seventeen ethanolic or aqueous extracts derived from eight Amazonian medicinal plants were evaluated for their activity against Herpes Simplex type 1 (HSV-1) and Chikungunya viruses (CHIKV).

CRISPR/sgRNA-directed synergistic activation mediator (SAM) as a therapeutic tool for Parkinson´s disease.

Parkinson`s disease (PD) is the second most prevalent neurodegenerative disease, and different gene therapy strategies have been used as experimental treatments. As a proof-of-concept for the treatment of PD, we used SAM, a CRISPR gene activation system, to activate the endogenous tyrosine hydroxylase gene (th) of astrocytes to produce dopamine (DA) in the striatum of 6-OHDA-lesioned rats. Potential sgRNAs within the rat th promoter region were tested, and the expression of the Th protein was determined in the C6 glial cell line.

Soluble mutant huntingtin drives early human pathogenesis in Huntington's disease.

Huntington's disease (HD) is an incurable inherited brain disorder characterised by massive degeneration of striatal neurons, which correlates with abnormal accumulation of misfolded mutant huntingtin (mHTT) protein. Research on HD has been hampered by the inability to study early dysfunction and progressive degeneration of human striatal neurons in vivo. To investigate human pathogenesis in a physiologically relevant context, we transplanted human pluripotent stem cell-derived neural progenitor cells (hNPCs) from control and HD patients into the striatum of new-born mice.

Objective: We sought to investigate prevalence, incidence and prognostic implications of permanent pacemaker (PPM) implantation in patients with cardiac amyloidosis (CA), thereby identifying the predictors of time to PPM implantation.

Methods: Seven hundred eighty-seven patients with CA (602 men, median age 74 years, 571 transthyretin amyloidosis (ATTR), 216 light-chain amyloidosis (AL)) evaluated at two European referral centres were retrospectively included. Clinical, laboratory and instrumental data were analysed.

Evaluation of the Effects of Chia ( L.) Leaves Ethanolic Extracts Supplementation on Biochemical and Hepatic Markers on Diet-Induced Obese Mice.

Obesity is a significant health concern affecting 13% of the world's population. It is often associated with insulin resistance and metabolic-associated fatty liver disease (MAFLD), which can cause chronic inflammation in the liver and adipose tissue. Obese hepatocytes show increased lipid droplets and lipid peroxidation, which can lead to the progression of liver damage.

Specific correction of pyruvate kinase deficiency-causing point mutations by CRISPR/Cas9 and single-stranded oligodeoxynucleotides.

Pyruvate kinase deficiency (PKD) is an autosomal recessive disorder caused by mutations in the gene. PKD-erythroid cells suffer from an energy imbalance caused by a reduction of erythroid pyruvate kinase (RPK) enzyme activity. PKD is associated with reticulocytosis, splenomegaly and iron overload, and may be life-threatening in severely affected patients.
