The study aimed to establish a bioassay for total bioactivity of Atractylodes lancea (AL) in human serum samples. Inhibition of bacterial growth (Staphylococcus aureus ATCC 25923) was assessed using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. The calibration curve (0, 0.39, 0.78, 1.56, 3.13, 2.56, and 50 ng/μl) was linear with correlation coefficients >0.990. The limit of quantification (LOQ) was 1.66 mg/ml using 20-ml serum sample. The developed bioassay method meets the standard of the bioanalytical method for determination of serum bioactivity of AL.

Staphylococcus aureus resides naturally in the nasal cavity of healthy individuals, including those working in restaurants, so they may be a source for spreading this bacterium to restaurant customers directly or indirectly through cooked meals. This bacterium has several virulence factors enabling it to cause many diseases in different parts of the body. It has also the capability to resist conventional antibiotics including methicillin. To investigate methicillin-resistant S. aureus (MRSA), 170 nasal swabs were collected from food preparation workers in 30 restaurants (5-6 workers in each restaurant) in Kirkuk city. After collection, the samples were directly transferred to the laboratory and cultured on selective media like mannitol salt agar (MSA). Microbiological examination including morphological, biochemical, and confirmatory tests showed that 24/170 of collected samples were positive for S. aureus with a rate of 14.12%. Among 24 isolates, 20 (83.3%) belonged to MRSA. All isolates were resistant to oxacillin and penicillin (100%), whereas sensitive to other antibiotics (gentamicin, chloramphenicol, and rifampicin). Polymerase chain reaction exhibited that 13 (65%) of MRSA isolates have toxic shock syndrome toxin-1 gene and only 4 (20%) have Panton-Valentine leukocidin gene.

Chromolaena odorata is an invasive plant with a broad spectrum of medicinal properties, including wound healing. This study aimed to evaluate the interaction of the already identified bioactive phytoconstituents from ethanolic extracts of C. odorata leaves with two angiogenesis-related proteins - vascular endothelial growth factor (VEGF) and cyclooxygenase-2 (COX-2) in silico. A molecular docking protocol was performed on AutoDock Vina employing the molecular structure of VEGF (3HNG) and COX-2 (3LN1) downloaded from the Protein Data Bank. The results reveal that most of the phytoconstituents possess strong binding affinity, where β-tocopherol and squalene have the highest values. In conclusion, it is highly possible that the phytoconstituents of C. odorata from the ethanolic leaf extract perform an interaction with VEGF and COX-2 and affect their activities.

The surface area determination has a vital role in measuring the properties of liquid and solid substances. Fluoride is a potent remineralizing agent of the teeth. The surface area is measured using a goniometer. The main aim of this study is to estimate the wettability of topical fluoride gel on the anterior and posterior teeth surfaces. Topical acidulated phosphate fluoride (APF) gel was taken in small quantities. Anterior and posterior teeth were collected, and their superficial unaltered enamel sections were used as the surface where the contact angle (CA) is determined. The surface wettability is determined using Ossila goniometer to measure CA. Each stage was mounted on a mechanical stage of the goniometer. A calibrated microsyringe was used to dispense drops of the APF gel over the surface of the specimen Group A (anterior tooth cut section) and Group B (posterior tooth cut section). This procedure is repeated for all specimen samples. The mean of CAs of the anterior teeth (88.41°) was greater when compared with the mean of posterior teeth (80.36°) CA. P value found using the paired t-test of SPSS software is found to be 0.271 (>0.05), hence statistically not significant. The greater the CA, the lower is the degree of wettability on the teeth surfaces. The mean CA of the topical fluoride APF gel on the anterior tooth surface is greater when compared to the posterior tooth surface. This signifies that greater wettability is seen on posterior tooth surfaces.

The current study's objective is to learn more about how patients, depending on their gender, perceive, feel, and know about orthodontic therapy.There was a cross-sectional survey among 100 patients to evaluate their knowledge and attitude toward orthodontic treatment. The questionnaire was prepared and circulated among patients using online google forms. The online responses were collected and tabulation of the data was done in excel sheets. Data was analysed using statistical software. Chi square test to compare the association of gender and patients knowledge regarding orthodontic treatment. In the current study 53% of the study population had visited an orthodontist. 79.6% of the patients are conscious that their teeth can be aligned properly by an orthodontist. 73.5% think that teeth should be properly positioned for a better facial appearance. According to the findings in the present study, it is evident that there is awareness and understanding regarding the orthodontic treatment among patients.

The aim is to create awareness about Patterson syndrome among dental students. Patterson-Stevenson-Fontaine syndrome is a very rare condition marked by irregular facial bone and tissue growth (mandibulofacial dysostosis) as well as limb abnormalities. A recessed jaw (retrognathism), cleft palate, and external ear defects are all possible symptoms of this disorder. A total of 112 undergraduate dental students participated in a longitudinal cross-sectional sample. To assess college students' awareness about Patterson syndrome, a self-administered, closed-ended questionnaire was developed and distributed. The only language allowed was English. The results were analyzed in SPSS software version 23. 10.71% of females and 14.29% of males were aware about Patterson syndrome. 32.14% of females and 38.39% of males were aware that Patterson syndrome was a rare adrenal disorder. We can conclude that very few of the population which was only 25% of the dental students were aware about Patterson syndrome and this survey helped in creating awareness about this syndrome.
