This study investigated the impact of adding hydroxyapatite nanoparticles to implant surfaces treated with zirconia blasting and acid etching (ZiHa), focusing on structural changes and bone healing parameters in low-density bone sites. The topographical characterization of titanium discs with a ZiHa surface and a commercially modified zirconia-blasted and acid-etched surface (Zi) was performed using scanning electron microscopy, profilometry, and surface-free energy. For the in vivo assessment, 22 female rats were ovariectomized and kept for 90 days, after which one implant from each group was randomly placed in each tibial metaphysis of the animals.

The digestive tract of fish has many morphological adaptations related to habitat and nutrition. Intestinal biometry may reflect these adaptations. Here, we aimed to describe histometric patterns in farmed fish and their relationship with feeding by using a standardized protocol considering cell density by tissue area.

Premise: Gall-inducing organisms change the development of their host plant organs, resulting in ontogenetic patterns not observed in the non-galled plants. Distinct taxa induce galls on Schinus spp., manipulating meristematic patterns in the host plant in distinct ways.

Article Synopsis
- Sclerotherapy is a treatment that involves injecting a chemical to close blood vessels, and this study investigates a new device, Flebogrif, for treating venous conditions in sheep.
- Nine Polish Merino sheep were divided into three groups (two experimental using Flebogrif with and without a sclerosant, and a control group) to assess how effective this method was in occluding veins.
- The results showed that using Flebogrif with a sclerosant led to significantly better outcomes in vein obstruction and wall changes compared to the other methods tested.
