Minimally invasive balloon-assisted sinus floor elevation vs. conventional transcrestal procedure in terms of new bone formation in a split-mouth Goettingen minipig model.

Purpose: Currently, maxillary sinus floor (SF) elevation is based on off-the-shelf allogeneic, xenogeneic or synthetic bone augmentation materials (BAM) that are implanted via an open lateral sinus wall approach (OSFE). However, this invasive method is associated with postoperative complications caused by an inadequate blood supply of the alveolar ridge. Balloon-assisted procedures are minimal invasive alternatives with lower complication rates.

The Effects of Daily Consumption of Functionalized Yogurts with Sacha Inchi Oil and Interspecific Hybrid Palm Oil on the Lipid Profile and ApoB/ApoA1 Ratio of Healthy Adult Subjects.

Sacha Inchi oil (SIO) and hybrid palm oil (HPO) are potential sources of unsaturated fatty acids to improve the lipid profile of dairy products. This study evaluated, for the first time, the effects of the daily consumption of yogurts with enhanced fatty acid profiles on plasma lipids related to cardiovascular disease (CVD) risk factors. A pilot, randomized, double-blind, parallel-controlled trial was conducted with 47 participants assigned to three groups: SIO-enriched yogurt (Group A), HPO-enriched yogurt (Group B), and plain yogurt (Group C).

Super-hydrophilic and super-lubricating Zwitterionic hydrogel coatings coupled with polyurethane to reduce postoperative dura mater adhesions and infections.

The dura trauma or large defects due to neurosurgical procedures can result in potential complications. Dural replacements have proven effective to reduce the risk of seizures, meningitis, cerebrospinal fluid leakage, cerebral herniation, and infection. Although various artificial dural patches have been developed, addressing iatrogenic infections and cerebral adhesions resulting from patches implantation remains a challenge.

Impact of a brief series of soccer matches on vascular conditions in youth women.

Background: Accumulative excessive physical load elevates central arterial stiffness and smooth muscular tone of peripheral vascular beds in endurance athletes. The aim of this study was to test the hypothesis that a brief series of soccer matches would increase central arterial stiffness and arterial wave reflection from the periphery in young female football players.

Methods: Fifteen subjects (17.

Physicochemical, medicinal chemistry, and ADMET characteristics of bee antimicrobial peptides as natural bio-preservatives to extend food shelf life: a roadmap for food safety regulation.

Antimicrobial peptides (AMPs) are gaining popularity as potential substitutes for conventional antibiotics and bio-preservatives in response to an increase in antimicrobial resistance cases. However, their poor pharmacokinetic profiles limit their applicability. This study using ADMETlab, OECD QSAR toolbox, and VEGA HUB virtual environments profiled 82 peptide sequences of seven bee antimicrobial peptides (BAMPs: abaecin, apamin, apisimin, apidaecin, defensin, hymenoptaecin, and melittin) using 81 descriptors combining physicochemical, medicinal chemistry, ADMET, and toxicophore criteria.

Effects of prebiotic and multispecies probiotic supplementation on the gut microbiota, immune function, and growth performance of weaned piglets.

In this study, we evaluated the impact of yeast cell wall prebiotics and multispecies probiotics on the gut microbiota, immune response, and growth performance of weaned piglets, as alternatives to antibiotics as growth promoters (AGPs). A randomized complete block design was employed, involving 160 piglets divided into four treatment groups during the nursery phase. The treatments applied throughout the experimental period were as follows: CONT+ = basal diet with halquinol (AGP); YCW = basal diet with yeast cell wall (cell wall of Saccharomyces cerevisiae yeast); SIM+ = basal diet with yeast cell wall + multispecies probiotic (Bacillus subtilis (2.

Lost in translation: the lack of agreement between surgeons and scientists regarding biomaterials research and innovation for treating bone defects.

Background: With over 2 million grafts performed annually, bone ranks second only to blood in the frequency of transplants. This high demand is primarily driven by the persistent challenges posed by bone defects, particularly following trauma or surgical interventions such as tumour excision. The demand for effective and efficient treatments has increased exponentially in the twenty-first century.

Therapeutic utility of Perfluorocarbon Oxygent in limiting the severity of subarachnoid hemorrhage in mice.

Subarachnoid hemorrhage (SAH) is the deadliest form of hemorrhagic stroke; however, effective therapies are still lacking. Perfluorocarbons (PFCs) are lipid emulsion particles with great flexibility and their much smaller size as compared to red blood cells (RBCs) allows them to flow more efficiently within the blood circulation. Due to their ability to carry oxygen, a specific PFC-based emulsion, PFC-Oxygent, has been used as a blood substitute; however, its role in cerebral blood flow regulation is unknown.

Scalable Production and Biophysical Characterization of High-Molecular-Weight Relaxed and Tense Quaternary State Polymerized Human Hemoglobin as Potential Red Blood Cell Substitutes.

High-molecular-weight (HMW) (>500 kDa) glutaraldehyde-polymerized human hemoglobin (PolyhHb) is a promising hemoglobin-based oxygen carrier (HBOC) due to its decreased risk of vasoconstriction and oxidative tissue injury. Previously, HMW tense (T) quaternary state PolyhHb was synthesized at the pilot scale with tangential flow filtration (TFF) for the removal of low-molecular-weight species. However, T-state PolyhHb is limited to specific biomedical applications due to its low oxygen affinity, thus motivating the need to produce high oxygen affinity relaxed (R) quaternary state PolyhHb at the pilot scale.

Evaluation of Two Anorganic Bovine Xenogenous Grafts in Bone Healing of Critical Defect in Rats Calvaria.

The purpose of this study was to provide an evaluation of two different xenogeneic bone substitutes in bone healing of critical-sized bone defects (Ø =5mm) created in rats calvaria. Thirty animals were randomized into 3 groups with one of the following treatments. In the control group (n=10), the defects were filled with blood clots; BO group (n=10), the defects were filled with bovine medullary bone substitute (Bio-Oss®); BF group (n=10), the defects were filled with bovine cortical bone substitute (Bonefill®).

The Biological Effect of Enriching the Plasma Content in Platelet-Rich Plasma: An In Vitro Study.

Background: Platelet-rich plasma (PRP) formulations have become valuable therapeutic tools in regenerative medicine. In addition, these blood derivates have been successfully included in cell therapy as fetal bovine serum substitutes, due to the real need to avoid the risk of host immunologic reactions and the animal disease transmission associated with reagents from animal origin. However, the protocols for obtaining them should be optimized to improve their biological potential.

Safe Food Coloring Agent as an Alternative to Eosin Stain.

Introduction Eosin stain is a commonly used histological dye that selectively binds to acidic structures in cells, imparting a color between pink and red. Eosin stain can be harmful due to its chemical composition. Inhaling eosin stain in powder form or as aerosolized droplets can cause irritation in the respiratory tract.
