Functions of Astrocytes after a Brain Disease
Neurons and glia (astrocytes, radial glia, oligodendroglia, and microglia) are the neural cells of the central nervous system (CNS). Glial cells have different functions; microglia are the resident macrophages in the CNS, oligodendrocytes are responsible for myelin production, NG2-positive glia is consistent with an oligodendrocyte progenitor function, and astrocytes play an important role both in homeostasis and in diseases.

Oral Health and Schizophrenia in Advanced Age
Schizophrenia is a psychiatric disorder that makes patients incompetent to perform day-to-day activities due to their progressing mental illness. In addition to disturbances with thoughts, behavioral changes, and impaired cognitive functions, oro-systemic health also becomes compromised.

Postoperative Facial Swelling and Occlusion in Orthognathic Treatment
Orthognathic surgery (OS) is usually performed to improve functional and esthetic parameters by repositioning the maxilla, mandible and/or the symphysis, particularly among patients that have either passed the pubertal growth spurt or may be unsuitable for orthodontic camouflage.

Optimal Insertion Torque for Orthodontic Anchoring Screw Placement
Eleven original articles with orthodontic anchoring screws (OASs) placement in humans including insertion torque (IT) and success rate were selected and were used to evaluate the relationships among IT, success rates, screw design, and placement methods at different sites. The ITs and success rates ranged from 6.0 ± 3.2 to 15.7 ± 2.3 Ncm and from 62.5 to 100.0% in the upper and lower buccal alveolar areas, respectively. For the mid-palatal area, the range was 14.5 ± 1.6 to 25.6 ± 5.5 Ncm and 83.0 to 100.0%, respectively. ITs of 5–12 and 6–14 Ncm were found to be optimal for the commonly used φ1.5–1.7 mm OASs in the upper and lower interproximal areas, respectively. In the mid-palatal suture area, ITs of 11–16 and 20–25 Ncm were considered suitable for tapered φ1.5 mm and φ2.0 mm OASs, respectively. Although identified optimal IT ranges deserve the recommendations, care must be taken to monitor the IT during placement constantly.

Oral Manifestations of Graft vs. Host Disease
Graft-versus-host disease (GVHD) is a complication of hematopoietic stem cell transplantation (HSCT). GVHD may also develop following solid transplants or blood transfusions if white blood cells are transferred. GVHD affects multiple organs, including the oral tissues.

Dental Implants in Relation to Bone Density
Titanium has been the material of choice for dental implant fixtures due to its exceptional qualities, such as its excellent balance of rigidity and stiffness. Since zirconia is a soft-tissue-friendly material and caters to esthetic demands, it is an alternative to titanium for use in implants. Nevertheless, bone density plays a vital role in determining the material and design of implants. Compromised bone density leads to both early and late implant failures due to a lack of implant stability.

Oncolytic Virotherapy for Head and Neck Cancer
Head and neck cancer (HNC) is a significant global health issue, and traditional treatments such as surgery, chemotherapy, and radiation therapy often have limited success, especially in advanced cases. Oncolytic virotherapy (OVT) offers a new approach.

Application of Silver in Medicine and Pharmacy
In the context of the growing resistance of microorganisms to available, widely used antibiotics, silver plays a key role. There is only one known case of bacterial resistance to silver—the Pseudomonas stutzeri strain, which naturally occurs in silver mines. The development of research in the field of coordination chemistry offers great opportunities in the design of new substances in which silver ions can be incorporated.

Oral Complications of Eating Disorder
Eating disorders (ED) patients were found to present related incidences of oral complications. Studies have reported that the possible course of an ED and comorbidities may be an imbalance in the oral environment. The results showed an association between biological (malnutrition, etc.), behavioral (binge eating episodes, vomiting, acidic diet, poor oral hygiene), and pharmacotherapeutic (addiction, hyposalivation) factors that may threaten oral health. Early diagnosis of the past and present symptoms is essential to eliminate and take control of destructive behaviors. Oral changes need to be tackled with medical insight, and additionally, the perception of dietary interactions is recommended.

Role of Mitochondrial Dysfunction in Oral Inflammatory Diseases
Oral inflammatory diseases (OIDs) include many common diseases such as periodontitis and pulpitis. The causes of OIDs consist microorganism, trauma, occlusal factors, autoimmune dis-eases and radiation therapy. When treated unproperly, such diseases not only affect oral health but also pose threat to people’s overall health condition. Therefore, identifying OIDs at an early stage and exploring new therapeutic strategies are important tasks for oral-related research. Mitochondria are crucial organelles for many cellular activities and disruptions of mitochondrial function not only affect cellular metabolism but also indirectly influence people’s health and life span. Increasing evidence suggests that mitochondrial dysfunction plays a critical role in the development and progression of OIDs and its associated systemic diseases.
