In autumn 2021, they organized an online colloquium with international early-career scientists from the chemical engineering community. Five guests were invited to give a scientific talk and provide insights into their career paths. The guests gave advice and emphasized the main challenges and opportunities during their early careers. Crucial points are networking, guidance, mentoring, as well as funding acquisition and the personal work-life balance

No full textThe Nachwuchs Reaktionstechnik (NaWuReT) is an organization of early-career chemical engineers of the DECHEMA/VDI subject division Reaction Engineering. In the spring of 2023, we organized a series of online lectures involving five invited speakers from industry to shed light on different career opportunities. The speakers gave insights into their individual career pathways and presented their current projects, both of which sparked active discussions among speakers and attendees

No full textWe investigated the effectiveness of four bioabsorbable interference screws for bone block fixation in ACL reconstruction, and assessed their complete absorption and graft integration. We performed a prospective clinical evaluation with the IKDC form and computed tomography (CT) scans 3, 6, 9, 12, 18 and 24 months after arthroscopic ACL reconstruction with the bonepatellar tendon-bone (BPTB) technique. A total of 20 patients was divided into five groups according to the type of screw used for the femoral fixation (half-tunnel technique): group A, poly L-lactic acid; group B, polyglyconate copolymer; group C, lactic acid and glycolic acid copolymer; group D, polylactic acid; and group E (control), titanium. Proximal bone graft integration was always achieved within 6 and 12 months. Cystic bone absorption was observed in two group A patients. Ten screws were absorbed (9 completely; 1 partially): 1 completely and 1 partially in group A at 9 and 24 months; 4 in Group B between 12 and 18 months; 4 in Group C (2 each at 12 and 24 months); and none in Group D. The IKDC ratings were: group A, four patients with A; group B, 2 with A, 1 with B and 1 with C; group C, 2 with A, 2 with B; group D, 4 with A. Effusion that resolved within 6 months was noted in 2 group A and 2 group C patients. One patient in group B had a traumatic re-rupture of the graft; the screw was not found when he was re-operated at 18 months. The four bioabsorbable interference screws provided safe and effective bone block fixation during ACL reconstruction. Their 93.75% excellent and good overall IKDC results were in line with those achieved with metal interference screws. The fact that none of the group D screws (polylactic acid) were absorbed at 2 years indicates that absorption of polylactic acid is a slow biological process. This is also suggested by the absence of effusion in this group
Abnormal scattergrams and cell population data generated by fully automated hematological analyzers: New tools for screening malaria infection?
No full textINTRODUCTION: Malaria is a life-threatening infectious disease, which has been for long confined to specific endemic areas. Nevertheless, the recent increase in immigration flows from endemic regions and imported cases has reemphasized many diagnostic challenges in Western countries, thus paving the way to introduce rapid and accurate strategies for screening subjects with suspected Malaria infection. Therefore, the aim of this article was to describe our recent experience with Sysmex XN-module for rapid screening of subjects with suspected Malaria. METHODS: Fourteen patients admitted to the Emergency Department (Papa Giovanni XXIII Hospital Bergamo, Italy) with a clinical suspicion of Malaria infection were evaluated, along with 1047 control samples. The analysis of peripheral blood was performed with XN-module, and results were then compared to optical microscopy. RESULTS: Nine patients were positive to Plasmodim falciparum, 3 to Plasmodim vivax, one to Plasmodim ovale, and one to Plasmodim malarie. Characteristic abnormalities could be observed in both white blood cell differential (WDF) and white cell nucleated (WNR) scattergrams (sensitivity 0.64 and specificity 1.0) in 9 samples with parasites at gametocyte or schizos stage irrespective of Plasmodium species and parasitic index, while characteristic scattergram abnormalities could not be seen in the 5 samples containing only parasites at the trophozoites stage. In these cases, specific variations of some cell population data (CPD) could be recorded (sensitivity 1.00 and specificity 0.91). CONCLUSION: The peculiar abnormalities observed in CPDs, WDF, and WNR-scattergrams may raise a definite suspicion of Malaria infection. Further studies should then be planned for validating these preliminary findings and assessing whether these specific abnormalities may be incorporated in rapid and inexpensive Malaria diagnostic algorithms
A comparative serum metabonomic analysis between Italian Duroc and Italian Large White pigs
No full textExtensive metabolic profiles of body fluids, obtained by nuclear magnetic resonance (NMR) spectroscopic or mass spectroscopic data, can provide information to deduce the effects of many different factors on biological processes. In particular, genetic factors can determine differences in physiological processes that are captured by metabolomics or metabonomics analyses. In this study we compared metabonomic profiles obtained from serum of two pig breeds (Italian Large White and Italian Duroc) with the aim to disentangle breed specific biological aspects. Twelve castrated males (6 Italian Large White and 6 Italian Duroc) were raised at the test station of the National Pig Breeders Association (ANAS) in the same conditions till they reached a live weight of about 160 kg. After a period of starvation, early in the morning pigs were transported all together at a commercial slaughterhouse, electrically stunned and jugulated within 10 minutes. Collected blood sample were processed after about 2 hours and serum was stored at -80°C till use. High Resolution Magic Angle Spinning-NMR serum spectra were recorded with a Bruker AVANCE spectrometer. Each sample was analysed in triplicate. Preliminary Principal Component Analysis of the obtained NMR spectra indicated that metabonomic analysis could be able to distinguish breed specific metabolic profiles. These results might represent useful information to disclose genetically determined regulatory pathways contributing to understand breed differences in biological processes indirectly linked with production traits

No full textThe vernacular sculpture of Saint Anthony the Abbot of Museo Colle del Duomo in Viterbo (Italy). Diagnostic and Wood dating
No full textThe sculpture of Sant'Antonio Abate represents an interesting example of vernacular art, it is a devotional object celebrated and carried in procession in many villages of Tuscia. The poor documentation and the observations of technical and stylistic characteristics do not allow the placement of the artifact at a well-defined period. It is also necessary to know the materials used for its realization before the start of restoration operations. Preliminary diagnostic investigations have allowed to date by radiocarbon, the sculpture, which was carved on lime wood, in the second half of the fifteenth century. XRF analysis has identified White Lead, Titanium and Zinc, this last in the habit of the sculpture. XRF data's interpretation is not so obvious because all the investigated repainted areas did not show strong compositional differences from the original ones. Re-depicting were assessed after stratigraphic sections. The obtained data support exploitation of the cultural heritage in the museum and are the basic information for restoratio
