Background: Morphological and functional cardiac involvement is rarely described in patients with inflammatory bowel disease (IBD) but there is evidence that they have an increased risk of cardiovascular (CV) events despite the lower prevalence of traditional CV risk factors.
Objectives: Our systematic review and meta-analysis examined the relationship between IBD and cardiac function, namely the incidence of heart failure (HF) and subclinical echocardiographic changes.
Data Sources And Methods: Two medical databases, PubMed and Scopus, were systematically searched up to September 2022 to identify all studies reporting HF and/or echocardiographic changes in IBD patients.

Aim: To evaluate in vitro the effect of laser photobiomodulation (PBM) combined or not with 30-nm hydroxyapatite nanoparticles (HANp), on the osteogenic differentiation of human umbilical cord mesenchymal stem cells (hUC-MSCs) by morphometric analysis using artificial intelligence programs (TensorFlow and ArcGIS).
Methods: UC-MSCs were isolated and cultured until 80% confluence was reached. The cells were then plated according to the following experimental groups: G1 -control (DMEM), G2 -BMP-2, G3 -BMP-7, G4 -PBM (660 nm, 10 mW, 2.

Background: Motion sickness (kinetosis) is a common and temporarily incapacitant ailment, manageable with behavioral as well as pharmacological measures.
Objective: To assess the effectiveness and safety of a combination of gamma-aminobutyric acid, glutamic acid, calcium, thiamine, pyridoxine, and cyanocobalamin (Group A) (n = 170) and extract of (ginger) (Group B) (n = 165) in the management of chronic complaints consistent with motion sickness.
Methods: Both groups were tested according to the following end points, under self-paired as well as comparative study designs: reduction of ≥20 score points in the total motion sickness assessment questionnaire (MSAQ) score, percentage of patients presenting a reduction of the total MSAQ score, absolute MSAQ score reduction, physician's assessment scores, final overall assessment of study medication, and willingness to continue treatment.

Aflatoxin B (AFB), ochratoxin A (OTA) and fumonisin B (FB) are among the most relevant agricultural mycotoxins, as they can induce various toxic processes in humans and animals. To detect AFB, OTA and FB in the most varied matrices, chromatographic and immunological methods are primarily used; however, these techniques are time-consuming and expensive.

Elderly IBD patients present specific challenges to the treating physician, as they have comorbidities, lower functional reserves, and higher risk of treatment-related complications. The diagnosis of IBD in the elderly may be difficult due to a more subtle disease presentation and to a wide range of differential diagnosis.

MicroRNA-9 (miR-9) modulates gene expression and demonstrates high structural conservation and wide expression in the central nervous system. Bioinformatics analysis predicts almost 100 ion channels, membrane transporters and receptors, including genes linked to primary familial brain calcification (PFBC), as possible miR-9-5p targets. PFBC is a neurodegenerative disorder, characterized by bilateral and symmetrical calcifications in the brain, associated with motor and behavioral disturbances.

One viable therapeutic modality for overcoming bacterial resistance can be photodynamic inactivation (PDI), a therapeutic modality for bacterial infection treatment. One of the main factors that can lead to an efficient PDI process is the association of metallic nanoparticles in the close vicinity of photosensitizers, which has shown promising results due to localized surface plasmon resonance phenomena.

Background: Since 1985, the author has been using the single central block technique for breast reduction and mastopexy, prioritizing the good relation between the final breast shape and the length of the scars, different from other authors who emphasize only the shape of the breast (Peixoto in Plast Reconstr Surg 65(2):217-225, 1980; Aesthet Plast Surg 8:231-236, 1984) and others who have drawn attention to the length of the scars (Arié in Rev Latinoam Cir Plast 3:23-31, 1957; Bozola in Plast Reconstr Surg 85:728-738, 1990; Sepúlveda in Rev Bras Cir 71(1):11-18, 1981). In this study, the author describes the use of a single central block of the mammary tissue and the nipple-areolar complex (NAC), dissected from the skin flaps and based on the superior vascular pedicle for reduction mammoplasty and mastopexy (Erfon et al. in Annals of the international symposium recent advances in plastic surgery, São Paulo, 1989; Hinderer (ed) Plastic surgery, Elsevier, Madrid, 1992; Proceedings of the 65th annual scientific meeting of the American society of plastic and reconstructive surgeons, Dallas, 1996).

δ-Toxin is a 26 amino acid peptide capable of lysing several mammalian cell types and subcellular structures. Structurally, δ-toxin predominantly exhibits a α-helical secondary structure in membranes but, in aqueous solution, it adopts varying helical content. As no atomic-level data is available for this peptide in aqueous solutions and for the water-to-membrane transition, this work aims to characterize δ-toxin behavior in these conditions through molecular dynamics simulations in triplicates employing four different parameter sets.
