During systemic Mm infection, wounding leads to increased infection burden, but the protective effect of Hif-1α stabilisation remains. Our data indicate that Hif-1α stabilisation alters neutrophil migration dynamics between comorbid sites, and that the protective effect of Hif-1α against Mm is maintained in the presence of inflammation, highlighting its potential as a host-derived target against TB infection.Conventional thoracic 4DCBCT scans take 1,320 projections over 4 minutes. This paper investigates which reconstruction algorithms best leverage Respiratory-Motion-Guided (RMG) acquisition in order to reduce scan time and dose while maintaining image quality. 3-Amino-9-ethylcarbazole compound library chemical We investigated a 200 projection, on average 1-minute RMG acquisition. RMG acquisition ensures even angular separation between projections at each respiratory phase by adjusting the imaging gantry rotation to the patient respiratory signal in real time. Conventional 1,320 projection data and RMG 200 projection data were simulated from 4DCT volumes of 14 patients. Each patient had an initial 4DCT reconstruction, treated as a planning 4DCT, and a 4DCT reconstruction acquired later, used for 4DCBCT data simulation and evaluation. Reconstructions were computed using the Feldkamp-David-Kress (FDK), McKinnon-Bates (MKB), RecOnstructiOn using Spatial and TEmporal Regularization (ROOSTER), and Motion Compensated FDK (MCFDK) algorithms. We also introduced and evaluated a novel MCMKB algorithm. Image quality was evaluated with Root-Mean-Square Error (RMSE), Structural SIMilarity index (SSIM) and Tissue Interface Sharpness (TIS). Rigid registration of the tumor volume regions between the reconstruction and the ground truth was used to evaluate geometric accuracy. Relative to conventional 4DCBCT acquisition, the RMG acquisition delivered 80% less dose and was on average 70% faster. The conventional-acquisition 4DFDK-reconstruction volumes had mean RMSE, SSIM, TIS and geometric error of 94, 0.9987, 2.69 and 1.19mm respectively. The RMG-acquisition MCFDK-reconstruction volumes had mean RMSE, SSIM, TIS and geometric error of 113, 0.9986, 1.76 and 1.77mm respectively with minimal increase in computational cost. These results suggest scan time and dose can be significantly reduced with minimal impact on reconstruction quality by implementing RMG acquisition and motion compensated reconstruction.Cancer patients use complementary and alternative medicine (CAM) to improve their well-being. Little is known about real risks. Objective To highlight 3 different types of axes 1/cancer patients' perceptions concerning CAM; 2/misinformation/miscommunication about CAM; 3/ CAM toxicity (direct toxicity, CAM-anticancer drugs, CAM-cancer interactions). Method A questionnaire was proposed to cancer patients for 2 months. The CAM toxicity was analyzed if patients documented their drugs and CAM. Results 85 patients responded 72/85 were taking ≥1 CAM. 95% patients were satisfied. There was an increasing CAM intake after cancer diagnosis. 117 different CAM were identified (63 herbs, 24 essential oils, 28 food supplements, 2 homeopathic specialities). Only 30/85 were aware CAM could interact with anticancer drugs. No other type of risk was perceived. Information sources 43/85 internet, 38/85 General Practitioner, 38/85 Community Pharmacist, 32/85 entourage, 25/85 other patients, 22/85 Oncologist. 81.3% questioned healthcare professionals (HCP) about CAM. 12 patients noticed HCP lacked knowledge regarding CAM. The toxicity analysis was carried out for 24 patients who consumed 1 to 24 CAM. 133 CAM were reported, including 87 different CAM. For only 43CAM/87, studies were found. All patients presented ≥1 risk 14 at risk of CAM-Cancer interactions, 15 of CAM-anticancer drug interactions, 21 of CAM direct toxicities. Conclusion Many CAM are used by patients. The diagnosis of cancer favors their use. The risks are manifold low perception of risk that can be induced by CAM, diverse and insecure sources of information and many potential toxicities that are not scientifically documented.Viral infections cause life-threatening diseases in millions of people worldwide every year and there is urgent need for new effective antiviral drugs. Hybridization of two chemically diverse compounds into a new bioactive effector product is a successful concept to improve the hybrid drug's properties compared to its parent compounds. In this study, (iso)quinoline-artemisinin hybrids, obtained via copper-catalyzed azide-alkyne cycloaddition (CuAAC) or organocatalyzed click reactions (in organic solvents or in the presence of water), were analyzed in vitro for the first time for their inhibitory activity against human cytomegalovirus (HCMV), as compared with their parent compounds and the reference drug ganciclovir. EC50 (HCMV) values were obtained in a range 0.22-1.20 µM, indicating highly potent antiviral properties in the absence of cytotoxic effects on normal cells (CC50 >100 µM). The most active hybrid 1 (EC50 = 0.22 µM) is 25 times more potent than its parent compound artesunic acid (EC50 = 5.41 µM) and 12 times more efficient than the standard drug ganciclovir (EC50 = 2.6 µM). Interestingly, hybrid 1 shows also inhibitory activity against hepatitis B virus in vitro (EC50 (HBeAg) = 2.57 µM).Aim The purpose of this retrospective study was to perform an evaluation of postoperative positional changes of the condyle and mandibular function after bilateral sagittal split osteotomy (BSSO) with manual proximal segment positioning. Patients 45 patients were divided into the 2 groups ‒ G1 (advancement ‒ 14 patients) and G2 (setback - 31 patients). Rigid internal fixation screws were utilized in all cases. Inclusion criteria were only BSSO, no TMJ symptoms preoperatively and age 18 or older. Results The differences between pre- and postoperative condyle position were evaluated using measurements taken from preoperative CT scans and compared to CT scans made a minimum of 6 months postoperatively. The positional changes in both the axial and sagittal planes were measured and compared. The recovery of mandibular function was evaluated by measuring maximal interincisal opening (MIO). The results revealed that condylar positional changes after BSSO in both groups were minimal and not significantly different for all three dimensions measured.
