Article Synopsis
  • The study compared three types of bioreactors for producing L-asparaginase, an enzyme linked to treating leukemia and lymphoma.
  • Cunninghamella echinulata DSM1905 was identified as the best strain for producing L-ASNase during initial screenings.
  • Among the bioreactors tested, the hybrid fixed-bed airlift (FB-ALR) system resulted in the highest enzyme activity, suggesting it is the most effective method for enzyme production.

The aim of this study was to evaluate the prevalence and length of the anterior loop (AL) of the inferior alveolar nerve, nerve emergence from the mental foramen, and prevalence of sensory disorders after implant placement in the interforaminal region. Four hundred and fifty hemimandibles (225 patients) were evaluated using cone beam computed tomography and panoramic radiographs. Information on the presence of sensory disorders was obtained from the medical records.

Background & Aims: The symptoms of xerostomia and taste alteration are adverse effects which frequently occur in patients under chemotherapy and once associated they can potentially impair their nutritional status. The aim of this study was to investigate the association of xerostomia and taste alterations in patients being treated by neoplastic chemotherapy.

Methods: Fifty patients scheduled to receive neoplastic chemotherapy were followed for their first two chemotherapy cycles for solid tumors and the Chemotherapy-Induced Taste Alteration Scale (CiTAS) was adopted.

Objective: The objective of this study was to assess inflammatory cytologic alterations in the oral epithelium of patients on human immunodeficiency virus pre-exposure prophylaxis (PrEP).

Material And Methods: Epithelial cells from the buccal mucosa of 30 patients were collected by exfoliative cytology and were evaluated according to inflammatory cellular alterations: karyomegaly, bi- or multinucleation, karyopyknosis, karyorrhexis, perinuclear halo formation, metachromasia, cytoplasmic vacuolization, indistinct cytoplasmic border, keratinization, and atrophy. Epithelial cells were collected initially before PrEP onset (T1) and then after 30 days of PrEP use (T2).

Background: During dental implants placement and bone augmentation procedures, it is important to determine the presence and location of mandibular canal anatomical variation in order to avoid injuries to inferior alveolar bundle. This study aimed to describe the prevalence and configuration of mandibular canal branching in the posterior region of the mandible using cone beam computed tomography (CBCT).

Methods: The interpretation of the images was conducted according to the presence, classification and location of the mandibular canal.

Urine has been a biological matrix of choice for drug screening, but recent advances in technology and the introduction of commercial oral fluid assays have effectively established oral fluid as a viable alternative matrix. This systematic review aimed to evaluate the sensitivity of oral fluid in detecting some illicit drugs compared to urine, and to compare the initial and final detection times of these drugs in both fluids. The electronic search in MEDLINE, Cochrane Library, Scopus, and Web of Science was carried out covering studies published from January 2003 and June 2019, in order to find all valid studies that detected drugs in oral fluid and urine in the same patient.

Rugby is played by more than 3 million people in over 100 countries on 5 continents. Playing rugby can result in 2-3 times more dental and facial trauma than American football or other contact sports. Facial trauma in sports has been associated with the development of temporomandibular disorders (TMDs).

Objective: This study was conducted to correlate and compare the immunoexpression of sex-determining region Y-box 2 (SOX-2) in oral leukoplakia (OL) lesions with that in normal buccal mucosa (control).

Materials And Methods: In this observational study, OL with low-risk (n = 34) and high-risk (n = 33) dysplasia and control samples (n = 25) were subjected to immunohistochemical analysis for SOX-2. In the epithelium, SOX-2 positive and negative cells, as well as semiautomatic segmentation of the immunopositive nuclear area were counted.

Purpose: This retrospective chart review study assessed patient records to determine implant insertion torque (IT) and implant stability quotient (ISQ) values during implant placement to evaluate the correlation with cortical bone anchorage (mono- or bicortical).

Methods: Primary stability data (IT during implant placement surgery and ISQ values immediately after implant placement) and cone beam computed tomography of 33 patients (165 implants) were assessed. Patients were divided into the following groups: G1, implants with apical cortical bone contact; G2, implants with bicortical bone contact (apical and cervical regions); and G3, implants with cervical cortical bone contact.

Unlabelled: Although some morphological investigations on aged human sublingual glands (HSG) found eventual phenomena identified as autolysis and mucous extravasation, the exact meaning of these findings has not been elucidated.

Objective: The aim of this work is to investigate whether acinar autolysis and mucous extravasation are related to the aging process in human sublingual glands. We also speculate if autolytic changes may assist forensic pathologists in determining time of death.
