This article proposes a streamlined approach for the development of ligand-oncotarget bioaffinity systems via integrated structural modeling and MD simulations, making use of proteomics, genomic, and X-ray crystallographic resources, to support targeted diagnosis and treatment of cancers and tumors.The mce1 operon of Mycobacterium tuberculosis, important for lipid metabolism/transport, host cell invasion, modulation of host immune response and pathogenicity, is under the transcriptional control of Mce1R. Hence characterizing Mce1R is an important step for novel anti-tuberculosis drug discovery. The present study reports functional and in silico characterization of Mce1R. In this work, we have computationally modeled the structure of Mce1R and have validated the structure by computational and experimental methods. Mce1R has been shown to harbor the canonical VanR-like structure with a flexible N-terminal 'arm', carrying conserved positively charged residues, most likely involved in the operator DNA binding. The mce1R gene has been cloned, expressed, purified and its DNA-binding activity has been measured in vitro. The Kd value for Mce1R-operator DNA interaction has been determined to be 0.35 ± 0.02 µM which implies that Mce1R binds to DNA with moderate affinity compared to the other FCD family of regulators. So far, this is the first report for measuring the DNA-binding affinity of any VanR-type protein. Despite significant sequence similarity at the N-terminal domain, the wHTH motif of Mce1R exhibits poor conservancy of amino acid residues, critical for DNA-binding, thus results in moderate DNA-binding affinity. The N-terminal DNA-binding domain is structurally dynamic while the C-terminal domain showed significant stability and such profile of structural dynamics is most likely to be preserved in the structural orthologs of Mce1R. In addition to this, a cavity has been detected in the C-terminal domain of Mce1R which contains a few conserved residues. Comparison with other FCD family of regulators suggests that most of the conserved residues might be critical for binding to specific ligand. The max pKd value and drug score for the cavity are estimated to be 9.04 and 109 respectively suggesting that the cavity represents a suitable target site for novel anti-tuberculosis drug discovery approaches.Hereditary angioedema (HAE) is a rare disease that causes episodic attacks of subcutaneous and submucosal edema, which can be painful, incapacitating, and potentially fatal. These attacks are mediated by excessive bradykinin production, as a result of uncontrolled activation of the plasma kallikrein/kinin system, which is caused by a C1 esterase inhibitor deficiency or dysfunction in HAE types 1 and 2, respectively. For many years, treatment options were limited to therapies with substantial adverse effects, insufficient efficacy, or difficult routes of administration. Increased insights in the pathophysiology of HAE have paved the way for the development of new therapies with fewer side effects. In the last two decades, several targeted novel therapeutic strategies for HAE have been developed, for both long-term prophylaxis and on demand treatment of acute attacks. check details This article reviews the advances in the development of more effective and convenient treatment options for HAE and their anticipated effects on morbidity, mortality, and quality of life. The emergence of these improved treatment options will presumably change current HAE guidelines, but adherence to these recommendations may become restricted by high treatment costs. It will therefore be essential to determine the indications and identify the patients that will benefit most from these newest treatment generations. Ultimately, current preclinical research into gene therapies may eventually lead the way towards curative treatment options for HAE. In conclusion, an increasing shift towards the use of highly effective long-term prophylaxis is anticipated, which should drastically abate the burden on patients with hereditary angioedema.
To study the caries status of 5, 12 and 15-year-old Greek children, assess how disease parameters are related to socio-demographic indicators and identify relevant trends at the national level.

A stratified cluster sample of 3702 children in total was randomly selected and examined clinically for caries (ICDAS II criteria). Caries experience was outlined by adapting ICDAS
criteria to the d/D component of the WHO dmf/DMF index configuration. Percentages (%) of caries experience-free children, of children with initial caries (ICDAS
), and the mean d
t/D
T, d
mft/D
MFT and d
mfs/D
MFS indices were calculated. The probability of presenting with d
t/D
T ≥ 1 was assessed by binary logistic regression analysis, whereas negative binomial regression models examined the effect of socio-demographic parameters on d
mfs/D
MFS indices (level of significance p ≤ 0.05).

60.1%, 48.1%, and 34.7% of the 5, 12, and 15-year-old children, respectively, had no caries experience at the defect level (d
mft/D
MFT = 0). Initial lesions (ICDAS
) were detected in 17.7%, 19.3% and 17.4% of the 5, 12 and 15-year-olds, accordingly. Mean d
t/D
T was 0.93, 1.70, and 2.51, whereas mean d
mft/D
MFT was 1.48, 1.61, and 2.46 for the 5, 12, and 15-year-olds, respectively. Children with higher educated parents and 15-year-old urban residents exhibited significantly less caries experience at the defect level. Initial caries lesions presented a significantly higher probability of being detected in urban-residing 5- and 15-year-olds, while no consistent trend could be identified for parental education level. Caries prevalence and experience levels declined for all age groups in ten years.

Although the dental health of Greek children has improved disparities remain, calling for organised primary and secondary preventive interventions.

Parents find it challenging to follow recommendations to brush young children after feeds at night despite the increase caries risk. This study compared three clinical recommendations (dilution, rinsing and wiping) on plaque pH after formula consumption.

Eighteen subjects were recruited. The five interventions with 2-week washout between visits included Rinse with undiluted formula for 30s (UF); rinse with 50% diluted formula for 30s (DF); rinse with undiluted formula for 30s, followed by rinsing with water for 1 minute (UF/R); rinse with undiluted formula for 30s, followed by wiping (UF/W); rinse with 10% sucrose for 30s as control (C). Plaque samples were collected at baseline, 2, 5, 10, 20 and 30min after the intervention and pH measured using the plaque sampling method.

UF/R resulted in significantly smaller pH drops at 5, 10 and 20min compared to UF. It also resulted in higher minimum pH (UF/R 6.34 ± 0.36 Vs UF 6.06 ± 0.40, p = 0.02), smaller maximum pH drop (UF/R 0.63 ± 0.35 Vs UF 0.90 ± 0.49, p = 0.03), smaller sum of change of hydrogen ion concentration (UF/R 9.22 × 10
 ± 7.8 × 10
Vs UF 2.30 × 10
 ± 2.6 × 10
, p = 0.04), and smaller area under the curve (UF/R 7.70 ± 5.44 Vs UF 13.44 ± 9.44, p = 0.02). DF and UF/W did not result in any significant pH change compared to UF.

Of the three clinical recommendations, only rinsing with water for 1min after undiluted formula reduced plaque acidogenicity. Teeth wiping with a moist cloth and 50% dilution of infant formula did not have an effect on plaque acidity.

To systematically review indexed literature related to the influence of mini-screw implant (MSI)-assisted intrusion on orthodontically induced inflammatory root resorption (OIIRR).

Indexed databases were searched without time and language restrictions using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The inclusion criteria were (a) original studies; (b) patients/subjects undergoing MSI-assisted intrusion; and (c) tomographic and/or histological assessment of OIIRR. Letters to the Editor, commentaries, case reports/series, reviews, and studies based on two-dimensional radiographic assessment of OIIRR were excluded. For experimental and clinical studies, the risk of bias assessment was performed using the Systematic Review Centre for Laboratory animal Experimentation risk of bias tool and the Risk of Bias in Non-randomized Studies of Interventions guidelines, respectively.

The initial search yielded 453 studies, out of which 6 (3 clinical and 3 on animal-models) were included. The clinical studies were performed on males and females with a mean age ranging between 16.07 and 25.5years. Duration of the clinical studies ranged from 3.8 to 9months. The animal studies were performed on mini-pigs, rats, and dogs. The mean age in the studies on rats and mini-pigs was 2.76 and 18months, respectively. In the study on canine models, mean age was not reported. In all studies, MSI-assisted intrusion was shown to cause OIIRR. Power analysis was performed in one study. All studies had a moderate risk of bias.

MSI-assisted intrusion is a risk factor for OIIRR; however, from a clinical perspective, further well-designed and power-adjusted studies are needed.

Dense Bone Islands (DBIs) are anatomic variants defined as radiopaque lesions consisting of hamartomatous cortical bone, often presenting as incidental radiographic findings. DBIs can also be known as idiopathic osteosclerosis, bone whorl, focal periapical osteopetrosis, bone scar and enostosis. We found a paucity of literature for management and reporting of this condition in children. For this reason, the authors describe sixteen cases of children and adolescents with dense bony islands and suggest a pathway for management.

Cases presented to the RNENT and Eastman Dental Hospital or private practice, either as chance findings or for diagnosis and treatment planning of undiagnosed radiopaque areas. The individuals were aged between 10 and 17years; 6 boys and 10 girls. All radiographic reports described DBIs. Diagnoses were confirmed by a Dental and Maxillofacial Radiology Consultant and advised no intervention. In some cases, monitoring was advised. Caution in orthodontic tooth movement was advised for five patients.

DBIs are common findings that seldom require treatment; however, caution should be exercised when undertaking orthodontic movement in the area of a DBI due to a potential risk of root resorption. Accurate identification and multidisciplinary management are of utmost importance.
