Intraoral extra-mucosal fixation of fractures in the atrophic edentulous mandible.

Atrophy of the mandible leads to a decrease in the bone mass, making it more vulnerable to fractures. A direct relationship has been demonstrated between the height of the bone in the area of the fracture and the incidence of postoperative complications of bone healing. Basic principles of fracture management in both edentulous and non edentulous patients are open reduction and internal fixation with osteosynthesis of the fracture to achieve restoration in terms of aesthetics and functionality. Several authors have discussed the advantages and disadvantages of the transoral and extraoral approaches. Between January 2007 and June 2011, 13 patients affected by bilateral fractures of atrophic mandibles were treated by extra-mucosal intraoral stabilization with satisfactory results. This approach reduces the risks of damage of the marginalis mandibulae nerve with low operation time, while avoiding unsightly scars

A BPA Approach to the Shroud of Turin

An investigation into the arm and body position required to obtain the blood pattern visible in the image of the Shroud of Turin, was performed using a living volunteer. The two short rivulets on the back of the left hand of the Shroud are only consistent with a standing subject with arms at a ca 45° angle. This angle is different from that necessary for the forearm stains, which require nearly vertical arms for a standing subject. The BPA of blood visible on the frontal side of the chest (the lance wound) shows that the Shroud represents the bleeding in a realistic manner for a standing position whilst the stains at the back - of a supposed post-mortem bleeding from the same wound for a supine corpse - are totally unrealistic. Simulation of bleeding from the nail wounds contacting wood surfaces yielded unclear results

Preliminary study of Australian Pinot noir wines by colour and volatile analyses, and the Pivot© Profile method using wine professionals

The aim of this preliminary study was to identify potential colour components, volatile and sensory attributes that could discriminate Pinot noir wines from five Australian winegrowing regions (Adelaide Hills, Yarra Valley, Mornington Peninsula, Northern and Southern Tasmania). The sensory analysis consisted of the Pivot© Profile method that was performed by wine professionals. A headspace solid-phase microextraction-gas chromatography-mass spectrometry method was used to quantify multiple volatile compounds, while the Modified Somers method was used for colour characterisation. Analysis of data suggested ethyl decanoate, ethyl 2-methylpropanoate, ethyl 2-methylbutanoate, in addition to decanoic acid as important contributors to the discrimination between regions. Similarly, wine hue, chemical age indices, total anthocyanin, and (%) non-bleachable pigment also discriminated wines between regions. The sensory analysis showed that wines from Mornington Peninsula were associated with the ‘red fruits’ aroma, ‘acidic’, and ‘astringency’ palate descriptors, while those from Adelaide Hills were associated with the ‘brown’ colour attribute. This study indicates regionality is a strong driver of aroma typicity of wine

Comparison of short- and long-term effectiveness of ixekizumab and secukinumab in real-world practice

Background: Although secukinumab and ixekizumab both act by inhibiting IL-17A, some scientific evidence suggests that there are differences in efficacy between the two agents. Objective: The aim of this study was to compare the short- and long-term effectiveness of ixekizumab and secukinumab in clinical practice. Methods: A retrospective study was conducted on a cohort of 245 psoriatic patients receiving secukinumab or ixekizumab during the period from September 2016 to December 2019. The proportion of patients achieving PASI75, PASI90, and PASI100 at weeks 12 and 24 was calculated. We recorded the 12- and 24-month drug survival as a measure to assess long-term effectiveness. Results: A higher proportion of patients in the secukinumab group achieved PASI75, 90, and 100 at 12 weeks. The Kaplan-Meier survival curve for any reason of discontinuation showed no differences between the two groups. Instead, the multivariate analysis for ineffectiveness, adjusted for potential confounders, showed a lower drug survival rate in the secukinumab group, with an adjusted HR of 2.57 (95% CI 1.05–6.28, p 0.038). Conclusion: This real-life study demonstrated that ixekizumab and secukinumab are both highly effective in short- and long-term treatment of psoriasis, even though few differences exist concerning speed of action and long-term effectiveness

Design, Synthesis, and Biological Evaluation of Pyridazinones Containing the (2-Fluorophenyl) Piperazine Moiety as Selective MAO-B Inhibitors

Twelve pyridazinones (T1-T12) containing the (2-fluorophenyl) piperazine moiety were designed, synthesized, and evaluated for monoamine oxidase (MAO) -A and -B inhibitory activities. T6 was found to be the most potent MAO-B inhibitor with an IC50 value of 0.013 µM, followed by T3 (IC50 = 0.039 µM). Inhibitory potency for MAO-B was more enhanced by meta bromo substitution (T6) than by para bromo substitution (T7). For para substitution, inhibitory potencies for MAO-B were as follows: -Cl (T3) > -N(CH3)2 (T12) > -OCH3 (T9) > Br (T7) > F (T5) > -CH3 (T11) > -H (T1). T6 and T3 efficiently inhibited MAO-A with IC50 values of 1.57 and 4.19 µM and had the highest selectivity indices (SIs) for MAO-B (120.8 and 107.4, respectively). T3 and T6 were found to be reversible and competitive inhibitors of MAO-B with Ki values of 0.014 and 0.0071, respectively. Moreover, T6 was less toxic to healthy fibroblast cells (L929) than T3. Molecular docking simulations with MAO binding sites returned higher docking scores for T6 and T3 with MAO-B than with MAO-A. These results suggest that T3 and T6 are selective, reversible, and competitive inhibitors of MAO-B and should be considered lead candidates for the treatment of neurodegenerative disorders like Alzheimer's disease
