56%), followed by not knowing where to access the vaccine 19/91 (20.88%). Conclusion The study highlights the need for strategies to ensure the availability of hepatitis B vaccine in conflict settings and need for vaccinology training given the suboptimal level of awareness and uptake of the hepatitis B vaccine among the healthcare workers. © The Author(s), 2020.Programmable cell adhesion with DNA hybridization is a promising approach for fabricating various tissue architectures without sophisticated instrumentation. this website However, little is known about how this artificial interaction influences the binding of cell adhesion proteins, E-cadherin. In this work, we designed a planar and fluid lipid membrane displaying E-cadherin and/or single-strand DNA with well-defined densities. Visualization of cells on membranes by fluorescence and interference microscopy revealed cell adhesion to be a two-step process artificial adhesion by DNA hybridization within a few minutes followed by biological adhesion via cadherin-cadherin binding within hours. Furthermore, we discovered that DNA hybridization can substantially facilitate E-cadherin-mediated cell adhesion. The promotive effect is probably due to the enforced binding between E-cadherin molecules in geometrical confinement between two membranes. Our in vitro model of cell adhesion can potentially be used to design functional synthetic molecules that can regulate cell adhesion via cell adhesion proteins for tissue engineering. © Author(s).Ground penetrating radar (GPR) investigations have the potential to non-destructively detect buried or hidden targets and are therefore often used in forensic research. This study presents a particular application of GPR methods to search for a missing person in a specific subsurface environment a natural cave. The search for missing people in Italy is a problematic and delicate task that needs improvement. Results of this study highlight not only the ability to detect both hollow and forensic targets, but also precisely locate and define their geometries. Moreover, GPR findings efficiently focus archaeological excavation and body recovery in an exact area and help to minimise time digging in erroneous places. © 2019 The Author(s).

It depends on adequate dental remains surviving the disaster and on the availability of dental records to be successful. This paper describes current practice in the techniques of identification in forensic odontology and outlines recent advances that are moving into the mainstream.Key PointsForensic odontology plays a key role in mass disaster victim identification (DVI) when good-quality antemortem (AM) dental records are available.Images including radiographs, computerized tomography (CT) data and three-dimensional (3D) scan data are considered more reliable AM records than written dental charts and odontograms.Interpretation, transcription and comparison of dental datasets are complex processes that should be undertaken only by trained dental professionals.The future of forensic odontology DVI techniques is likely to include the use of 3D datasets for comparison. © 2019 The Author(s).

He presented with bloody stool and underwent examination, including lower gastrointestinal endoscopy, and he was diagnosed with rectal cancer. Since he had a history of multiple abdominal surgeries, including Hartmann's operation, severe pelvic adhesions were expected. Thus, in consideration of surgical safety and curability, transanal total mesorectal excision (Ta-TME) was performed. The duration of the surgery was 3 h, and there was minimal blood loss. Histopathological findings did not reveal remnants of cancer in the resected margin, and the patient was discharged on hospital day 7. Rectal cancer has a higher rate of local recurrence than colon cancer. To prevent local recurrence, ensuring a rectal circumferential resection margin (CRM) with TME is essential, which is, however, challenging in obese patients and in those with giant tumors, contracted pelvis, prostatic hypertrophy, etc., since these conditions complicate pelvic surgery. The same is true for patients with a history of multiple abdominal surgeries. It is expected that these problems can be resolved by Ta-TME. In the present case, Ta-TME was extremely useful in rectal cancer surgery for a patient with a history of multiple abdominal surgeries, including Hartmann's operation.

Methods We retrospectively evaluated, using the three different modalities, the metastatic status of LPLNs in four regions, including both the internal iliac and the obturator, in 46 patients affected by lower rectal cancer patients who underwent LPLN dissection. The size inclusion criterion for LPLN metastasis was set at 6 mm in the short axis diameter. Histological examination was performed for determining the false positive and negative rate of LPLNs metastasis detection. Results Among 184 LPLNs regions, 17 (9%) were positive for metastasis. The region-based sensitivity, specificity, and accuracy rate did not differ among the three tested diagnostic modalities. Moreover, a significant increase in these rates could not be observed when the modalities were combined. Of 184 regions, 8 (4.4%) were false negative, whereas 2 (1.1%) were false positive. The histological pattern of metastatic regions did not differ in 8 false negative LPLNs. Conclusions Each modality had a similar detection power for LPLNs metastasis, with a cut-off value at 6 mm in the short axis diameter. However, the sensitivity of all the modalities was slightly low, along with the number of false negative LPLNs. Further reduction of the false negative rate with these modalities may be difficult because of an inherent limitation of current imaging technologies to accurately detect lymph node metastases.
