Background: Clinically significant macular edema (CME) is the leading cause of visual loss after ophthalmologic surgery due to the release of inflammatory mediators promoted by the procedures. We aimed to evaluate the outcomes of intravitreal Ozurdex (700 µg dexamethasone) implants as a primary therapeutical option for post-surgical macular edema cases.

Methods: Patients with post-surgical macular edema diagnosed by optical coherence tomography (Cirrus SD-OCT) and treated with Ozudex were selected for the current study.

This study focuses on the analysis of a unique composition between two well-established models, known as the Logistic-Gauss map. The investigation cohesively transitions to an exploration of parameter space, essential for unraveling the complexity of dissipative mappings and understanding the intricate relationships between periodic structures and chaotic regions. By manipulating control parameters, our approach reveals intriguing patterns, with findings enriched by extreme orbits, trajectories that connect local maximum and minimum values of one-dimensional maps.

Background: Chronic low-grade inflammation in obesity is linked to white adipose tissue (WAT) dysfunction. Plasma lipopolysaccharide (LPS) activates Toll-like receptor 4 (TLR4), triggering NF-κB and worsening these disturbances. Previously, we showed that histone H3 lysine 27 (H3K27) epigenetic modifications affect WAT gene expression in high-fat-diet mice, identifying key pathways in adipose-derived stem cells (ASCs).

Classical preimplantation embryo culture is performed in static fluid environments. Whether a dynamic fluid environment, like the fallopian tube, is beneficial for embryo development remains to be determined across mammalian species. Objectives of these proof-of-concept studies were to determine if controllable dynamic microfluidic culture would enhance preimplantation murine, bovine, and human embryo development compared to static culture.

Introduction: Anthropometric, demographic, genetic, and clinical features may affect cognitive, behavioral, and functional decline, while clinical trials seldom consider minimal clinically important differences (MCIDs) in their analyses.

Methods: MCIDs were reviewed taking into account features that may affect cognitive, behavioral, or functional decline in clinical trials of new disease-modifying therapies.

Results: The higher the number of comparisons of different confounders in statistical analyses, the lower values will be significant.

This study aims to use superparamagnetic iron oxide nanoparticles (SPIONs), specifically magnetite (FeO), to deliver deflazacort (DFZ) and ibuprofen (IBU) to Duchenne muscular dystrophy-affected (DMD) mouse muscles using an external magnetic field. The SPIONs are synthesized by the co-precipitation method, and their surfaces are functionalized with L-cysteine to anchor the drugs, considering that the cysteine on the surface of the SPIONs in the solid state dimerizes to form the cystine molecule, creating the FeO-(Cys)-DFZ and FeO-(Cys)-IBU systems for tests. The FeO nanoparticles (NPs) were characterized by Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, powder X-ray diffraction (PXRD), transmission electron microscopy (TEM), dynamic light scattering (DLS), and magnetic measurements.

Introduction And Objective:  This study presents and analyzes the content of an online Evidence Gap Map (EGM), "", which graphically represents evidence from systematic reviews (SRs) of human clinical trials in homeopathy that were published from 1991 to 2021. The EGM was built according to the guidelines of the International Initiative for Impact Evaluation (3ie), adapted for complex interventions, to represent visually relevant evidence and research gaps.

Presentation Of Evidence Gap Map Content:  The interventions, classified as rows, are characterized in the EGM not only by the homeopathic therapeutic strategy but also by individual medicines and potencies.

In obesity, C-C chemokine ligand 2 (CCL2) plays a critical role in recruiting macrophages to white adipose tissue (WAT), contributing to chronic inflammation. In this study, we sought to explore the effects of fish oil (FO) on CCL2 expression and histone (H3K27)-modifying enzymes in both human model of preadipocytes and primary adipose-derived stem cells (ASCs). Present findings in preadipocytes lineage evidenced that lipopolysaccharide (LPS) increased (∼5.

Purpose: One of the main causes of chronic wounds is diabetes mellitus (DM), a metabolic disease characterized by chronic hyperglycemia. In this context, hydrogels have been used as a promising treatment for stimulating tissue ingrowth and healing in these injuries. This systematic review aimed to evaluate the findings of studies that investigated the effects of injectable hydrogels of various origins on skin wound healing using in vivo experimental models in diabetic rats.

Skin wounds are extremely frequent injuries related to many etiologies. They are a burden on healthcare systems worldwide. Skin dressings are the most popular therapy, and collagen is the most commonly used biomaterial, although new sources of collagen have been studied, especially spongin-like from marine sponges (SPG), as a promising source due to a similar composition to vertebrates and the ability to function as a cell-matrix adhesion framework.

Immunogenic recombinant Mayaro virus-like particles present natively assembled glycoprotein.

NPJ Vaccines

December 2024

Instituto Politécnico Nacional, IPN. Av. Luis Enrique Erro s/n. Unidad Adolfo López Mateos, Mexico City, Mexico.

Virus-like particles (VLPs) are an established vaccine platform and can be strong immunogens capable of eliciting both humoral and cellular immune responses against a range of pathogens. Here, we show by cryo-electron microscopy that VLPs of Mayaro virus, which contain envelope glycoproteins E1-E2 and capsid, exhibit an architecture that closely resembles native virus. In contrast to monomeric and soluble envelope 2 (E2) glycoprotein, both VLPs as well as the adenovirus and modified vaccinia virus Ankara (MVA) vaccine platforms expressing the equivalent envelope glycoproteins E1-E2, and capsid induced highly neutralising antibodies after immunisation.

Electronic address:

This mini-review explores the potential of precision medicine and personalized nutrition in addressing health challenges faced by perimenopausal women, focusing on the role of genetic polymorphisms in key metabolic pathways. Specifically focus on the single nucleotide polymorphisms (SNPs) in the COMT, FUT2, and MTHFR genes, which influence neurotransmitter metabolism, gut microbiota composition, and folate homeostasis, respectively. These polymorphisms are critical in modulating hormonal fluctuations, metabolic imbalances, and nutrient absorption during perimenopause.
