Article Synopsis
  • The study investigates the impact of polystyrene (PS) nanoplastics on the larvae of Chironomus riparius, focusing on DNA damage and gene expression related to various stress responses after 24-hour exposure to environmentally relevant doses of PS NPs.
  • Results indicated a significant genotoxic effect, evidenced by increased DNA strand breaks and decreased expression of genes responsible for DNA repair and other crucial biological processes like cellular stress, development, and oxygen transport.
  • The findings suggest that PS NPs may disrupt the endocrine system and inhibit critical physiological functions in these aquatic organisms, highlighting potential ecological risks stemming from plastic pollution in water bodies.

Background: Ossifying fibromyxoid tumor of soft parts (OFMT), is a rare but morphologically distinctive neoplasm of uncertain histogenesis that most frequently affects middle-aged male adults. Clinically, it usually presents as a slowly enlarging, small, circumscribed mass, which in most cases is painless. OFMT is most frequently found within the subcutaneous tissues of extremities or trunk, and rarely in the oral/head and neck region.

Background: Three-dimensional (3D) printing is relatively a new technology with clinical applications, which enable us to create rapid accurate prototype of the selected anatomic region, making it possible to plan complex surgery and pre-bend hardware for individual surgical cases. This study aimed to express our experience with the use of medical rapid prototype (MRP) of the maxillofacial region created by desktop 3D printer and its application in maxillofacial reconstructive surgeries.

Material And Methods: Three patients with benign mandible tumors were included in this study after obtaining informed consent.

Background: Dental procedures in the maxilla typically require multiple injections and may inadvertently anesthetize facial structures and affect the smile line. To minimize these inconveniences and reduce the number of total injections, a relatively new injection technique has been proposed for maxillary procedures, the anterior and middle superior alveolar (AMSA) nerve block, which achieves pulpal anesthesia from the central incisor to second premolar through palatal approach with a single injection. The purpose of this article is to provide background information on the anterior and middle superior alveolar nerve block and demonstrate its success rates of pulpal anesthesia using the conventional syringe.

The simple bone cyst, as newly classified by WHO in 2005, is a lesion related to the jawbones. Therefore, it is not a cyst, since it is a cavity devoid of epithelial tissue. It is a rare pathology affecting the mandible more than the maxilla.

Objectives: Treated HIV-1-infected patients with lipodystrophy often develop insulin resistance and proatherogenic dyslipidaemia. Zinc alpha-2 glycoprotein (ZAG) is a recently characterized adipokine which has been shown to be involved in the development of obesity and metabolic syndrome in uninfected subjects. We assessed the relationship between circulating ZAG levels and metabolic derangements in HIV-1-infected patients receiving antiretroviral drugs.

Article Synopsis
  • - The study investigates how prior experience with audiovisual stimuli affects our ability to perceive simultaneity in language, specifically comparing English and Spanish speakers.
  • - Results showed that when listening to sentences in their native language, participants needed to see visual speech precede the audio by a longer time compared to when listening in a non-native language.
  • - As participants gain more experience with a non-native language, the differences in how they process visual and auditory signals tend to lessen, highlighting how visual information influences our perception of timing in audiovisual communication.
