Abstract
With advances in commercial space launch capabilities and reduced costs to orbit, humans may arrive on Mars within a decade. Both to preserve any signs of past (and extant) martian life and to protect the health of human crews (and Earth's biosphere), it will be necessary to assess the risk of cross-contamination on the surface, in blown dust, and into the near-subsurface (where exploration and resource-harvesting can be reasonably anticipated). Thus, evaluating for the presence of life and biosignatures may become a critical-path Mars exploration precursor in the not-so-far future, circa 2030. This Special Collection of papers from the Atacama Rover Astrobiology Drilling Studies (ARADS) project describes many of the scientific, technological, and operational issues associated with searching for and identifying biosignatures in an extreme hyperarid region in Chile's Atacama Desert, a well-studied terrestrial Mars analog environment. This paper provides an overview of the ARADS project and discusses in context the five other papers in the ARADS Special Collection, as well as prior ARADS project results.

Abstract
OBJECTIVE Since the first use of silicone implants by Cronin in 1962, there have been several attempts to introduce alternative filling materials for breast implants on the market. A promising new development are lightweight implants, whose filler material is one third lighter than conventional silicone gel. While these implants have been used primarily for aesthetic augmentation, a benefit could be expected particularly in post-mastectomy reconstruction. MATERIALS AND METHODS Since 2019, 92 operations using lightweight implants have been performed at our clinic, 61 of them for breast reconstruction after mastectomy. These have been compared to 92 breast reconstructions using conventional silicone implants. RESULTS The average volume of the lightweight implants was 30% higher than of the conventional implants (452 ml resp. 347 ml), whereas the implant weight was comparable in both groups (317 g resp. 347 g). Grade 3-4 capsular fibrosis was seen in 6 cases in both groups; revision was required 9 times (lightweight implants) and 7 times (conventional silicone implants) during the follow-up period. DISCUSSION To our knowledge, this is the first study to investigate the use of lightweight implants in breast reconstruction. With exception of the filler material, the implants used in the two groups were comparable in shape and surface. The inserted lightweight implants had a greater volume but nearly the same weight as the conventional implants and were used in patients with a higher body mass index. Thus, lightweight implants were preferred in patients whose reconstruction required a larger implant volume. CONCLUSION Lightweight implants are a new alternative for breast reconstruction especially in case that larger implant volume is demanded. The increased complication rate has to be verified in further studies.

Abstract
Technology has revolutionized the way dentists are able to treat their patients. These technological advances have paved the way for the creation of virtual patient models utilizing these 3-dimensional intra-oral patient models, cone bean computer tomography (CBCT) radiograph scans, extraoral 3-dimensional scans, and jaw motion tracings to create a patient-specific model. These models are advantageous in planning surgical treatments by providing 3-dimensional views of vital anatomical structures to accurately identify the location, size, and shape of a structure or defect in order to plan accordingly. Virtual augmentation of either hard tissue (bone) and/or soft tissue (i.e., gingiva) can also be accomplished.Technology has allowed the capture of the dynamic motions of the jaw and combined them with the virtual patient to develop permanent restorations in harmony with the patient's orofacial complex. With the introduction of new technology in the realm of digital dentistry, patient care is being brought to a new and higher level. This creates a level of more optimal care that a dentist can deliver to patients.

Abstract
BACKGROUND Reconstructive surgery is established as a standard treatment option after mastectomy due to cancer. It is crucial to patients to achieve a natural and symmetric looking breast through reconstruction. Anthropometric measurements are used to assess the objective symmetry of the breast, which are prone to errors and difficult to reproduce. OBJECTIVE The aim of this work is to validate breast volumetry using three-dimensional surface imaging. METHODS We compared preoperatively analog and digitally evaluated volume of the breast with our gold standard, direct water displacement measurement of the mastectomy specimen. We examined 34 breast specimens in total. RESULTS Each measurement method (Breast Sculptor, VAM, Breast-V) for breast volume/mass determination demonstrates acceptable agreement ranges when compared with resected volumes and masses. The strongest volumetry instrument is Breast Sculptor (digital), the weakest is Breast-V (analog). CONCLUSIONS 3D surface imaging is a quick, effective, and convenient method to evaluate breast shape and volume. The accuracy, reproducibility, and reliability of 3D surface imaging were comparable with MRI in our study.This takes us a step closer to the long-term goal of establishing robust instruments to plan breast reconstructive surgery, achieve better surgical results, and contribute to quality assurance in breast surgery.

Abstract
Background Computer-assisted teaching is becoming increasingly more important to acquire new knowledge and skills in medical curricula. The consequence of gender-characteristic personality traits on academic performance in e‑learning examinations are difficult to forecast. This study investigated gender-related differences in examination behavior among undergraduate medical students taking a web-based quiz. Methods A total of 1315 4th grade medical students at the Medical University of Vienna completing the compulsory online moodle-based ECG quiz 2017/2018 were enrolled into this observational study. Individual data of examination behavior and quiz results as well as results of the final annual exam were extracted. Students were grouped into 10 strata according to academic performance. Variables between both sexes were compared using a nonparametrical test. Examination variables were correlated to performance. Results Of the total study population 686 (52%) were female and 629 (48%) were male. The time until the first attempt and number of attempts performed was comparable between both sexes, however female students spent more time on the first attempt compared to their male colleagues (1592 sec [Q1–Q3: 999–2536] vs 1405 sec [Q1–Q3: 828–2395], p = 0.002), suggesting a higher self-discipline and risk-aversity. There was no difference regarding quiz scores or final ECG examination scores between female and male students (p = 0.869 and p = 0.396). Students who accessed the quiz earlier and less time spent for the first attempt tended to perform better at the final examination (rs = 0.20, p < 0.001 and rs = −0.15, p < 0.001). Conclusions Gender-related differences in examination behavior already described for nononline based examinations are similarly observable in e‑learning. For this test, gender-immanent traits seem not to twist final examination results and impact academic performance.

Abstract
A crucial mode of action of trastuzumab is the labeling of HER2-positive (HER2+) tumor cells for the eradication by natural killer (NK) cells, a process called antibody-dependent cellular cytotoxicity (ADCC). However, despite widespread HER2 expression among cancer entities, only a fraction, with robust HER2 overexpression, benefits from trastuzumab therapy. ADCC requires both sufficient lymphocytic infiltration and close binding of the immune cells to the antibody-tagged tumor cells. We hypothesized that the chemokine CX3CL1 could improve both processes, as it is synthesized as a membrane-bound, adhesive form that is eventually cleaved into a soluble, chemotactic protein. Here, we show that CX3CL1 overexpression is a positive prognostic marker in breast cancer. CX3CL1 overexpression attracted tumor-suppressive lymphocytes, including NK cells, and inhibited tumor growth and lung metastasis in the syngeneic 4T1 breast cancer mouse model. In HER2+ SKBR3, MDA-MB-453, and HT-29 tumor cells, CX3CL1 overexpression increased NK cell-mediated cytotoxicity in vitro and acted synergistically with trastuzumab. Even though CX3CL1 did not further improve trastuzumab efficacy in vivo in the trastuzumab-sensitive MDA-MB-453 model, it compensated for NK-cell depletion and prolonged survival. In the HER2 low-expressing HT-29 model, however, CX3CL1 overexpression not only prolonged survival time but also overcame trastuzumab resistance in a partly NK cell-dependent manner. Taken together, these findings identify CX3CL1 as a feasible pharmacologic target to enable trastuzumab therapy in HER2 low-expressing cancers and render it a potential predictive biomarker to determine therapy responders.

Abstract
Purpose BRCA mutation carriers have an increased risk of developing breast or ovarian cancer. Risk-reducing bilateral salpingo-oophorectomy (RRBSO) is associated with a decrease in risk for tubal and ovarian cancer. Hormone replacement therapy (HRT) may increase breast, ovarian, and endometrial cancer risk in the general population. This review analyses the published data on HRT and risk of cancer in BRCA mutation carriers with and without RRBSO. Methods We included all relevant articles published in English from 1995 to October 2020. Sources were identified through a search on PubMed and Cochrane Library. Results We included one case–control and one retrospective cohort study on ovarian and one case–control study on endometrial cancer risk and HRT in BRCA mutation carriers. Regarding breast cancer risk, one case–control study on BRCA mutation carriers with and without RRBSO and one case–control study, one Markov chain decision model, two prospective cohort studies, and one metaanalysis on carriers after RRBSO were included. For ovarian cancer, results were ambiguous. For breast cancer, most studies did not find an adverse effect associated with HRT. However, some of the studies found a risk modification associated with different formulations and duration of use. Conclusion Although data are limited, HRT does not seem to have a relevant effect on cancer risk in BRCA mutation carriers. RRBSO should not be postponed to avoid subsequent HRT in this population. Adequate HRT after RRBSO should be offered to avoid chronic diseases resulting from low estrogen levels. However, further data on the safety of different formulations are needed.

Introduction
Coronary CT angiography (CCTA) plays an increasing role in the detection and risk stratification of patients with coronary artery disease (CAD). The Coronary Artery Disease – Reporting and Data System (CAD-RADS) allows for standardized classification of CCTA results and, thus, may improve patient management.
Purpose
Aim of this study was to assess the impact of CCTA in combination with CAD-RADS on patient management and to identify the impact of cardiovascular risk factors (CVRF) on CAD severity.
Methods
CCTA was performed on a third-generation dual-source CT scanner in patients, who were referred to a radiology centre by their attending physicians. In a total of 4801 patients, CVRF were derived from medical reports and anamnesis.
Results
The study population consisted of 4770 patients (62.0 (54.0-69.0) years, 2841 males) with CAD (CAD-RADS 1-5), while 31 patients showed no CAD and were excluded from further analyses. Age, male gender and the number of CVRF were associated with more severe CAD stages (all p < 0.001). 3040 patients (63.7 %) showed minimal or mild CAD requiring optimization of CVRF i.e. medical therapy but no further assessment at his time. A group of 266 patients (5.6 %) had a severe CAD defined as CAD-RADS 4B/5. In the multivariate regression analysis, age, male gender, history of smoking, diabetes mellitus and hyperlipidaemia were significant predictors for severe CAD, whereas arterial hypertension and family history of CAD did not reach significance. Of note, a subgroup of 28 patients (10.5 %) with a severe CAD (68.5 (65.5-70.0) years, 26 males, both p = n.s.) had no CVRF.
Conclusions
CCTA in combination with the CAD-RADS allowed for effective risk stratification of CAD patients. The majority of the patients showed non-obstructive CAD and, thus, could be treated conservatively without the need for further CAD assessment. CVRF out of arterial hypertension and family history had an impact on CAD severity reflected in higher CAD-RADs gradings. Of note, a relevant fraction of patients with CAD did not have any CVRF and, thus, may not be covered by risk stratification models.

Abstract
Purpose Mutations in the genes BRCA1 and BRCA2 represent a significant risk factor for ovarian and breast cancer. With increasing number and success rates, fertility protection and treatment are gaining importance also for BRCA1/2 mutation carriers. However, the effect on primary cancer risk and risk for recurrence remains unclear. This review analyses the published data on fertility treatment and risk of ovarian and breast cancer in BRCA1/2 mutation carriers. Methods In this review, we included all relevant articles published in English from 1995 to 2018. Literature was identified through a search on PubMed and Cochrane Library. Results We identified one retrospective cohort and one case–control study regarding the association of fertility treatments and ovarian cancer risk in BRCA mutation carriers. The studies show no increase in ovarian cancer risk. Furthermore, one case–control study on the association between fertility treatment and breast cancer risk in BRCA mutation carriers and one prospective cohort study on the long-term safety of medication used for fertility preservation in women with a history of breast cancer were identified. One of the studies shows a possible adverse effect for gonadotropin-containing medication. Conclusion Possible increases in cancer risk associated with fertility treatments in BRCA1/2 mutation carriers cannot be excluded at this time. Based on the existing studies, BRCA1/2 mutation carriers should not be generally excluded from fertility treatments. However, they have to be informed about limited data and possible increases in cancer risk.

Abstract
PURPOSE BRCA mutation carriers have an increased risk of developing breast or ovarian cancer. Oral contraception (OC) is known to increase breast cancer and reduce ovarian cancer risk in the general population. This review analyses the published data on OC and risk of cancer in BRCA mutation carriers. METHODS We included all relevant articles published in English from 1995 to 2018. Literature was identified through a search on PubMed and Cochrane Library. RESULTS We included four meta-analyses, one review, one case-control study and one retrospective cohort study on the association between ovarian cancer and OC in BRCA mutation carriers. All report a risk reduction for the OC users and several also describe an inverse correlation with duration of use. Regarding breast cancer, we included four meta-analyses, one review, one case-control study, two case-only studies, one prospective and one retrospective cohort study. Some studies report a risk elevation, while others did not find an association between OC use and breast cancer in BRCA mutation carriers. In other studies, the association was limited to early-onset breast cancer and/or associated with young age at first start of OC. CONCLUSION Oral contraception leads to a risk reduction of ovarian cancer also in BRCA mutation carriers. An increase in breast cancer risk due to OC cannot be excluded. Women with BRCA mutation who consider OC use have to be informed about possible increase in breast cancer risk and alternative contraceptive methods. OC should not be used for the prevention of ovarian cancer in this population.

Abstract
PURPOSE Annual cervical cancer screening is recommended in Germany as a part of the statutory preventive care. Abnormal results can provoke psychological distress and anxiety, compromising women's adherence. Little is known about how a cervical dysplasia impacts adherence follow-up visits and prevention habits over time. To optimize care strategies, this study aims to identify women at risk for nonadherence to follow-up visits after a screening event. METHODS Between November 2015 and May 2017, participants with an abnormal Pap smear at the Heidelberg and Leipzig University Hospitals received a four-part questionnaire (sociodemographic data, PHQ-D, self-designed fear and prevention habit questions) at the first consultation (T1) and subsequently after 3 (T2) and 6 (T3) months; healthy controls completed the questionnaire at T1. RESULTS 132 women with an abnormal Pap smear [with conization: S1 (n = 68, 51.5%), without intervention: S2 (n = 64, 48.5%)] and healthy controls (K, n = 101) generally adhered to gynecological checkups, except S1 6 months after the first diagnosis (S1/T3 - 0.47, signed rank p < 0.0005). Knowledge of primary prevention information, i.e., HPV vaccination, was significantly higher among K (K 58%, S1 29%, S2 44%, Chi-squared p = 0.01) as was vaccine uptake (K 39% versus S1/S2 7% and 17%, respectively, Chi-squared p = 0.0004). Fear of upcoming Pap smears rose significantly over time (S1/T1-S1/T2-S1/T3, Wilcoxon signed-rank test p < 0.001) and was higher among those with conization at T2 (Chi-square test, p = 0.01) and partially accompanied by panic disorders at T1 (Chi-square test p = 0.035). Realization of general preventive habits rose significantly among women without an operative procedure (S2) over the study. CONCLUSION This study advances the understanding of non-participation in follow-up visits after a dysplasia diagnosis, identifying post-conization women as a special risk group for decreased adherence.

Abstract
Mutations and activation of the PI3K signaling pathway in breast cancer cells have been linked to brain metastases. However, here we describe that in some breast cancer brain metastases samples the protein expression of PI3K signaling components is restricted to the metastatic microenvironment. In contrast to the therapeutic effects of PI3K inhibition on the breast cancer cells, the reaction of the brain microenvironment is less understood. Therefore we aimed to quantify the PI3K pathway activity in breast cancer brain metastasis and investigate the effects of PI3K inhibition on the central nervous system (CNS) microenvironment. First, to systematically quantify the PI3K pathway activity in breast cancer brain metastases, we performed a prospective biomarker study using a reverse phase protein array (RPPA). The majority, namely 30 out of 48 (62.5%) brain metastatic tissues examined, revealed high PI3K signaling activity that was associated with a median overall survival (OS) of 9.41 months, while that of patients, whose brain metastases showed only moderate or low PI3K activity, amounted to only 1.93 and 6.71 months, respectively. Second, we identified PI3K as a master regulator of metastasis-promoting macrophages/microglia during CNS colonization; and treatment with buparlisib (BKM120), a pan-PI3K Class I inhibitor with a good blood-brain-barrier penetrance, reduced their metastasis-promoting features. In conclusion, PI3K signaling is active in the majority of breast cancer brain metastases. Since PI3K inhibition does not only affect the metastatic cells but also re-educates the metastasis-promoting macrophages/microglia, PI3K inhibition may hold considerable promise in the treatment of brain metastasis and the respective microenvironment.

Abstract
Pediatric heart transplantation requires lifelong immune suppression and may require thymectomy, both of which alter T-cell repertoires. We hypothesized that atopic and autoimmune diseases are more common in pediatric heart transplant patients than the general population, and that transplantation in early childhood increases the risk of development or worsening of atopic or autoimmune disease. A cross-sectional single-center study including 21 heart transplant patients aged ≤18 years was conducted. Data collected included age at transplant, induction, thymectomy, and development and severity of atopic or autoimmune disease. A majority (67%) reported having any atopic disease post-transplant, all of whom reported onset or worsening post-transplantation. Thymectomized patients were significantly more likely to have asthma (P = 0.018) and report asthma worsening post-transplant (P = 0.045). Patients with worsening of asthma post-transplant were transplanted at a significantly younger age (P = 0.040). ABO incompatible and ABO compatible recipients presented similarly. Anemia was common (38%) but not always clearly of autoimmune origin. Atopic diseases are common in children following heart transplantation: Compared to the general population, there is a higher prevalence of eczema (43% vs 11%) and asthma (33% vs 9%). Both thymectomy and younger age at transplant are associated with atopic disorders, possibly due to altered T-cell repertoires.

Abstract
ZusammenfassungDie pigmentierte villonoduläre Synovialitis (PVNS oder PVS) ist eine seltene benigne proliferative Erkrankung des Synovialgewebes der Gelenke und Sehnenscheiden. Man unterscheidet die diffuse, lokal aggressiv destruierend wachsende Verlaufsform von der nodulären, lokalisierten, eher verdrängend wachsenden Form. Die Diagnosestellung gelingt in der Regel zuverlässig mittels klinischem Befund, Röntgen und MRT, beweisend ist jedoch nur die Histologie. Die Therapie der Wahl besteht in der marginalen chirurgischen Resektion, befundabhängig als arthroskopische oder offene (Teno)synovialektomie durchgeführt, bei intraartikulär diffusem Befall kombiniert mit adjuvanter RSO. Rezidivraten liegen auch nach Kombinationstherapie im Bereich von fünf bis zehn Prozent.

Abstract
STUDY QUESTION What is the success rate in terms of ovarian activity (menstrual cycles) as well as pregnancy and delivery rates 1 year after orthotopic ovarian transplantations conducted in a three-country network? SUMMARY ANSWER In 49 women with a follow-up >1 year after transplantation, the ovaries were active in 67% of cases and the pregnancy and delivery rates were 33 and 25%, respectively. WHAT IS KNOWN ALREADY Cryopreservation of ovarian tissue in advance of cytotoxic therapies and later transplantation of the tissue is being performed increasingly often, and the total success rates in terms of pregnancy and delivery have been described in case series. However, published case series have not allowed either a more detailed analysis of patients with premature ovarian insufficiency (POI) or calculation of success rates based on the parameter 'tissue activity'. STUDY DESIGN, SIZE, DURATION Retrospective analysis of 95 orthotopic transplantations in 74 patients who had been treated for cancer, performed in the FertiPROTEKT network from 2008 to June 2015. Of those 95 transplantations, a first subgroup (Subgroup 1) was defined for further analysis, including 49 women with a follow-up period >1 year after transplantation. Of those 49 women, a second subgroup (Subgroup 5) was further analysed, including 40 women who were transplanted for the first time and who were diagnosed with POI before transplantation. PARTICIPANTS/MATERIALS, SETTING, METHODS Transplantation was performed in 16 centres and data were transferred to the FertiPROTEKT registry. The transplantations were carried out after oncological treatment had been completed and after a remission period of at least 2 years. Tissue was transplanted orthotopically, either into or onto the residual ovaries or into a pelvic peritoneal pocket. The success rates were defined as tissue activity (menstrual cycles) after 1 year (primary outcome) and as pregnancies and deliveries achieved. MAIN RESULTS AND THE ROLE OF CHANCE The average age of all transplanted 74 women was 31 ± 5.9 years at the time of cryopreservation and 35 ± 5.2 at the time of transplantation. Twenty-one pregnancies and 17 deliveries were recorded. In Subgroup 1, tissue was cryopreserved at the age of 30 ± 5.6 and transplanted at 34 ± 4.9 years. Ovaries remained active 1 year after transplantation in 67% of cases (n = 33/49), the pregnancy rate was 33% (n = 16/49) and the delivery rate was 25% (n = 12/49). In Subgroup 5, tissue was cryopreserved at the age 30 ± 5.9 years and transplanted at 34 ± 5.2 years. Ovaries remained active 1 year after transplantation in 63% of cases (n = 25/40), the pregnancy rate was 28% (n = 11/40) and the delivery rate was 23% (n = 9/40). The success rates were age dependant with higher success in women who cryopreserved at a younger age. In Subgroup 5, tissue was exclusively transplanted into the ovary in 10% (n = 4/40) of women and into a peritoneal pocket in 75% (n = 30/40), resulting in spontaneous conceptions in 91% of patients (n = 10/11). LIMITATIONS, REASONS FOR CAUTION The data were drawn from a retrospective analysis. The cryopreservation and transplantation techniques used have changed during the study period. The tissue was stored in many tissue banks and many surgeons were involved, leading to heterogeneity of the procedures. However, this does reflect the realistic situation in many countries. Although patients with POI were evaluated before transplantation to allow specific analysis of the transplanted tissue itself, the possibility cannot be excluded that residual ovarian tissue was also reactivated. WIDER IMPLICATIONS OF THE FINDINGS This is the largest case series worldwide to date and it confirms that cryopreservation and transplantation of ovarian tissue can be a successful option for preserving fertility. Persistent tissue activity 12 months after transplantation suggests that the pregnancy and delivery rates may increase further in the future. As transplantation into the peritoneum results in a high success rate, this approach may be an alternative to transplantation into the ovary. However, in order to establish the best transplantation site, a randomized study is required. STUDY FUNDING/COMPETING INTEREST This study was in part funded from the Deutsche Forschungsgemeinschaft (# DI 1525) and the Wilhelm Sander Foundation (2012.127.1) and did not receive any funding from a commercial company. No competing interests. TRIAL REGISTRATION NUMBER None.

Abstract
The ribosomal S6 kinase RSK2 is essential for osteoblast function, and inactivating mutations of RSK2 cause osteopenia in humans with Coffin-Lowry syndrome (CLS). Alveolar bone loss and premature tooth exfoliation are also consistently reported symptoms in CLS patients; however, the pathophysiologic mechanisms are unclear. Therefore, aiming to identify the functional relevance of Rsk2 for tooth development, we analyzed Rsk2-deficient mice. Here, we show that Rsk2 is a critical regulator of cementoblast function. Immunohistochemistry, histology, micro-computed tomography imaging, quantitative backscattered electron imaging, and in vitro assays revealed that Rsk2 is activated in cementoblasts and is necessary for proper acellular cementum formation. Cementum hypoplasia that is observed in Rsk2-deficient mice causes detachment and disorganization of the periodontal ligament and was associated with significant alveolar bone loss with age. Moreover, Rsk2-deficient mice display hypomineralization of cellular cementum with accumulation of nonmineralized cementoid. In agreement, treatment of the cementoblast cell line OCCM-30 with a Rsk inhibitor reduces formation of mineralization nodules and decreases the expression of cementum markers. Western blot analyses based on antibodies against Rsk1, Rsk2, and an activated form of the 2 kinases confirmed that Rsk2 is expressed and activated in differentiating OCCM-30 cells. To discriminate between periodontal bone loss and systemic bone loss, we additionally crossed Rsk2-deficient mice with transgenic mice overexpressing the osteoanabolic transcription factor Fra1. Fra1 overexpression clearly increases systemic bone volume in Rsk2-deficient mice but does not protect from alveolar bone loss. Our results indicate that cell autonomous cementum defects are causing early tooth loss in CLS patients. Moreover, we identify Rsk2 as a nonredundant regulator of cementum homeostasis, alveolar bone maintenance, and periodontal health, with all these features being independent of Rsk2 function in systemic bone formation.

Abstract
Water in its three ambient phases plays the central thermodynamic role in the terrestrial climate system. Clouds control Earth's radiation balance, atmospheric water vapour is the strongest "greenhouse" gas, and non-equilibrium relative humidity at the air-sea interface drives evaporation and latent heat export from the ocean. On climatic time scales, melting ice caps and regional deviations of the hydrological cycle result in changes of seawater salinity, which in turn may modify the global circulation of the oceans and their ability to store heat and to buffer anthropogenically produced carbon dioxide. In this paper, together with three companion articles, we examine the climatologically relevant quantities ocean salinity, seawater pH and atmospheric relative humidity, noting fundamental deficiencies in the definitions of those key observables, and their lack of secure foundation on the International System of Units, the SI. The metrological histories of those three quantities are reviewed, problems with their current definitions and measurement practices are analysed, and options for future improvements are discussed in conjunction with the recent seawater standard TEOS-10. It is concluded that the International Bureau of Weights and Measures, BIPM, in cooperation with the International Association for the Properties of Water and Steam, IAPWS, along with other international organisations and institutions, can make significant contributions by developing and recommending state-of-the-art solutions for these long standing metrological problems in climatology.

Abstract
Digital dentistry is increasing prevalent throughout general dental practice. Scanned impression systems, CAD/CAM software, milling units, and 3D printers are becoming used with regularity by some private practitioners. This case report describes a combination of multiple technologies including intraoral scanning, 3D printing, and traditional impression and processing techniques used for fabricating a removable partial denture. The patient indicated that he was highly satisfied throughout the course of treatment and especially with the final result. Future technology will continue to evolve and be more widely used in removable prosthodontics and other areas of dentistry.

Abstract
The authors present a case study in which a virtual model was created from a patient's cone beam computed tomographic scans that simulated a dentoalveolar defect associated with periapical pathosis. With the information provided by the virtual model, the tooth was extracted, and both defect and alveolus were virtually grafted. The virtual amount calculated was similar to the amount used in the actual site.

Abstract
A 17-year-old male with burns to 8% of his total body surface area was treated for 10 days with Acticoat(®), a nanocrystalline silver dressing. The burns, which were on his back and shoulder, healed without infection. However, a skin discoloration in the wound area and the adjacent uninjured skin appeared in the first days of treatment. The staining remained visible even after the treatment had ended and disappeared approximately three years later. Despite the outstanding antimicrobial properties, possible side effects of silver nanocrystalline dressings should be kept in mind.
