Addressing Antimicrobial Properties in Guided Tissue/Bone Regeneration Membrane: Enhancing Effectiveness in Periodontitis Treatment.

Guided tissue regeneration (GTR) and guided bone regeneration (GBR) are the two surgical techniques generally used for periodontitis disease treatment. These techniques are based on a barrier membrane to direct the growth of new bone and gingival tissue at sites with insufficient volumes or dimensions of bone or gingiva for proper function, esthetics, or prosthetic restoration. Numerous studies have highlighted biocompatibility, space-creation, cell-blocking, bioactivity, and proper handling as essential characteristics of a membrane's performance.

The Relationship Between Nurse's Professional Quality of Life, Mindfulness, and Hardiness: A Cross-Sectional Study During the COVID-19 Outbreak.

Background: In the pandemic of Coronavirus Disease 2019 (COVID-19) disease, various factors, such as workplace factors, and psychological variables, can affect the occupational status of nurses. This study aimed to assess the relationship between nurses' professional quality of life, mindfulness, and hardiness during the outbreak of COVID-19.

Methods: This cross-sectional study included 239 nurses from two medical centers in Rafsanjan, Iran.

Psychosocial status during the prevalence of COVID-19 disease: the comparison between healthcare workers and general population.

The prevalence of COVID-19 disease continues to be a significant psychosocial status among health care workers (HCWs) and the general population worldwide. This cross sectional study aimed to compare the psychosocial status between healthcare workers and general population during the prevalence of COVID-19 disease in southeast Iran. Totally 415 health care workers of a medical service center for COVID-19 patients and 1023 people of general population participated in the study.

Dual spinneret electrospun nanofibrous/gel structure of chitosan-gelatin/chitosan-hyaluronic acid as a wound dressing: In-vitro and in-vivo studies.

Structural and compositional similarity to the natural extracellular matrix (ECM) is a main characteristic of an ideal scaffold for tissue regeneration. In order to resemble the fibrous/gel structure of skin ECM, a multicomponent scaffold was fabricated using biopolymers with structural similarity to ECM and wound healing properties i.e.

Hyaluronic acid coated electrospun chitosan-based nanofibers prepared by simultaneous stabilizing and coating.

Chitosan (CS) and hyaluronic acid (HA) are two oppositely charged natural polysaccharides used widely for preparation of nanofibrous scaffolds for tissue engineering applications. Here, we prepared composite fibers composed of CS and HA by electrospinning and subsequent coating. In this regard, two approaches were applied for coating CS nanofibers by HA.
