ine quantification in iodine images.
70/Sn150 kVp presented the lowest image noise and highest detectability in VMIs of two small focal liver lesions. 100/Sn150 kVp presented the lowest image noise on mixed images and highest accuracy of iodine quantification in iodine images.Obesity is increasing worldwide with significant healthcare implications. We searched PubMed/MEDLINE, Embase and Cochrane Library for articles registered until June 2020 to explore the relationship between obesity, urinary (UI) and anal incontinence (AI). Obesity is associated with low-grade, systemic inflammation and pro-inflammatory cytokine release, producing reactive oxygen species and oxidative stress (1). This alters collagen metabolism and, in combination with increased intraabdominal pressure, contributes to UI development. Whereas in AI, stool consistency may be a factor. Weight loss can reduce UI and should be a management focus, however effect on AI is less clear. Keywords Obesity, Urinary incontinence, Anal incontinence.The translocon SecYEG and the associated ATPase SecA form the primary protein secretion system in the cytoplasmic membrane of bacteria. The secretion is essentially dependent on the surrounding lipids, but the mechanistic understanding of their role in SecA SecYEG activity is sparse. Here, we reveal that the unsaturated fatty acids (UFAs) of the membrane phospholipids, including tetraoleoyl-cardiolipin, stimulate SecA SecYEG-mediated protein translocation up to ten-fold. Biophysical analysis and molecular dynamics simulations show that UFAs increase the area per lipid and cause loose packing of lipid head groups, where the N-terminal amphipathic helix of SecA docks. While UFAs do not affect the translocon folding, they promote SecA binding to the membrane, and the effect is enhanced up to fivefold at elevated ionic strength. Tight SecA lipid interactions convert into the augmented translocation. Our results identify the fatty acid structure as a notable factor in SecA SecYEG activity, which may be crucial for protein secretion in bacteria, which actively change their membrane composition in response to their habitat.This systematic review and meta-analyses aimed to synthesize evidence of the link between bariatric surgery and changes in food preferences, considering the method of assessment. MEDLINE, Cochrane Library, Web of Science, Cinahl, PsychINFO, ProQuest, and Open grey were searched incorporating two blocks of terms ("Intervention" and "Food Preferences"). Interventional or observational studies involving patients (BMI ≥ 35 kg m-2 ) with sleeve gastrectomy (SG) or Roux-en-Y Gastric Bypass (RYGB) and a control group were included. Meta-analyses were performed comparing the standardized daily mean percentage energy from proteins, carbohydrates, and lipids between preoperative and postoperative patients. Fifty-seven studies concerning 2,271 patients with RYGB and 903 patients with SG met the inclusion criteria, of which 24 were eligible for meta-analysis. Despite a total reduction in macronutrient intakes, the meta-analyses revealed a postoperative increase in percentage energy from proteins at 12 months (0.24, 95% CI 0.03, 0.46, I2 = 73%) and a decrease in percentage energy from fat at 1 month (-0.47, 95% CI 0.86, 0.09, I2 = 72%), up to 24 months (-0.20, 95% CI -0.31, 0.08, I2 = 0%). In conclusion, the present systematic review and meta-analyses showed changes of food preferences in terms of macronutrient, food selection and, overall food appreciation up to 5 years following bariatric surgery.
We aimed to synthesize the published evidence to evaluate the preventive efficacy of ginger on postoperative nausea and vomiting (PONV).
A systematic review and meta-analysis were conducted in this study.
PubMed, EMBASE, Cochrane Library, and CINAHL were systematically searched from their outset to October 2020, without language limitation. Randomized controlled trials (RCTs) comparing the effects of ginger and prophylactic antiemetics or placebo on PONV were included. Data were analyzed by the fixed effects model or random effects models regarding the results of heterogeneity.
A total of 14 studies involving 1417 participants were included. Compared with placebo, the ginger group had significantly lower nausea severity (MD=-0.71, 95% CI=-1.37 to -0.06, p=0.03) and lower proportion of rescue antiemetic use (RR=0.71, 95% CI=0.62-0.82, p<0.001; RR=0.71, 95% CI=0.56-0.91, p<0.001). The ginger group had significantly lower incidence of nausea and vomiting over 6h after operation (RR=0.68, 95% CI=0.55-0.85, p<0.001; RR=0.78, 95% CI=0.42-1.44, p=0.43) compared with placebo. When compared with the prophylactic antiemetic group, the ginger group had significantly lower incidence of nausea (RR=0.75, 95% CI=0.56-0.99, p=0.04), but no significant differences in the incidence of vomiting and proportion of rescue antiemetic use were found.
Ginger was effective for the prevention of PONV. More RCTs comparing ginger and other prophylactic antiemetics are needed to evaluate whether ginger could replace the traditional prophylactic antiemetics.
This study's results could be used as an evidence for all patients following surgery who are at risk of PONV without allergy to ginger.

Primary and secondary implant stability is of high importance for survival and success of dental implants in the short and long term. Measurements of implant stability during healing provide the opportunity to monitor the course of the osseointegration process.
To compare implant stability quotient (ISQ) by resonance frequency analysis (RFA), recorded with two different devices after implant placement.
Patients with the need of single tooth extraction in posterior sites of the maxilla and the mandible were treated in a surgical center. All patients received additional augmentation with a bovine bone substitute and platelet-rich fibrin (PRF) after atraumatic tooth extraction. After a healing period of 10 weeks, 28 self-tapping titanium-implants were placed. Implant stability was recorded with two different devices (Osstell and Penguin) at the time of implant insertion (T0), 10 days later (T1), and after 7 (T2), or 17 weeks (T3).
No implant was lost, and no postoperative complication occurred during fole suitable for RFA-measurement and revealed comparable results. Due to the cordless design, handling of the Penquin device was more comfortable. Reusability of the Penguin MultiPeg-transducers may offer an additional benefit with regard on ecological aspects.Bed bugs, Cimex lectularius L. and C. hemipterus (F.) (Hemiptera Cimicidae) are hematophagous ectoparasites of humans. Since the resurgence of bed bugs in the late 1990s there has been a corresponding emphasis on development and implementation of integrated pest management (IPM) programs to manage infestations. One critical requirement of IPM is the ability to detect and monitor the target pest. We outline and describe the majority of all known existing devices and technologies developed for bed bug detection and monitoring as well as much of the underlying science. Almost 40 detection and monitoring products have flooded the marketplace, but for various reasons, including price, size, complexity and lack of independent scientific evaluation, they have not been widely adopted for IPM in structures. One product, the ClimbUp® Insect Interceptor, has nine competitors that utilize a similar design. this website This review also discloses many other technologies and products that are either too expensive or too impractical for use as either consumer or industrial products. We conclude that there is a critical need for inexpensive and effective detection and monitoring traps and lures suitable for widespread adoption by the urban pest control industry. © 2021 Society of Chemical Industry.Generation time determines the pace of key demographic and evolutionary processes. Quantified as the weighted mean age at reproduction, it can be studied as a life-history trait that varies within and among populations and may evolve in response to ecological conditions. We combined quantitative genetic analyses with age- and density-dependent models to study generation time variation in a bird metapopulation. Generation time was heritable, and males had longer generation times than females. Individuals with longer generation times had greater lifetime reproductive success but not a higher expected population growth rate. Density regulation acted on recruit production, suggesting that longer generation times should be favoured when populations are closer to carrying capacity. Furthermore, generation times were shorter when populations were growing and longer when populations were closer to equilibrium or declining. These results support classic theory predicting that density regulation is an important driver of the pace of life-history strategies.Histone modification is aberrantly regulated in cancer and generates an unbalanced state of gene transcription. VprBP, a recently identified kinase, phosphorylates histone H2A on threonine 120 (T120) and is involved in oncogenic transcriptional dysregulation; however, its specific role in colon cancer is undefined. Here, we show that VprBP is overexpressed in colon cancer and directly contributes to epigenetic gene silencing and cancer pathogenesis. Mechanistically, the observed function of VprBP is mediated through H2AT120 phosphorylation (H2AT120p)-driven transcriptional repression of growth regulatory genes, resulting in a significantly higher proliferative capacity of colon cancer cells. Our preclinical studies using organoid and xenograft models demonstrate that treatment with the VprBP inhibitor B32B3 impairs colonic tumor growth by blocking H2AT120p and reactivating a transcriptional program resembling that of normal cells. Collectively, our work describes VprBP as a master kinase contributing to the development and progression of colon cancer, making it a new molecular target for novel therapeutic strategies.
A research agenda for oral health care was established in the Netherlands using the Dialogue Model. This project served as a case study in which we applied boundary-work theory as a framework to understand boundaries (ie demarcations) between and within groups, and how these boundaries can be overcome.
To gain insights into the boundaries encountered when setting a research agenda, we analysed how this agenda served as a boundary object (ie circumstances, situations or material that connect actor groups and allow boundary crossing) that facilitated crossing boundaries and uniting the perspectives of patients and practitioners.
We used a thematic approach to analyse researchers' observations, meeting materials, emails, interviews with patients (n=11) and a survey among patients and practitioners (n=18).
Setting the research agenda helped to cross boundaries in oral health care, which demonstrates its role as a boundary object. First, this made it possible to integrate research topics representing the perspectives and priorities of all patients and also to unite those perspectives. It was essential to involve practitioners at an early stage of the project so that they could better accept the patients' perspectives. This resulted in support for an integrated research agenda, which facilitated the crossing of boundaries.
The research agenda-setting project was found to serve as a boundary object in uniting the perspectives and priorities of patients and practitioners.
Patient involvement in this case study was structured in the process of research agenda setting using the Dialogue Model.
