Chemosensory proteins (CSPs) are thought to play essential roles in insect chemical communication, but their exact physiological functions remain unclear.

In this study, we investigated the functions of the CSP2 gene in the whitefly Bemisia tabaci using protein expression and the binding affinity spectrum of CSP2 to different types of odor molecules. Moreover, the evolutionary characteristics of the CSP2 gene were studied. The data obtained using binding assay showed that the CSP2 protein can bind to a broad range of plant volatiles including the homoterpene (E)-3,8-dimethyl-1,4,7-nonatriene (DMNT) and its analogs. In addition, using a behavioral experimental approach we identified that DMNT can repel the selection and oviposition of B. tabaci. Furthermore, protein structure modeling, molecular docking analyses and a functional mutation experiment were carried out resulting in the final identification of key amino acid residue Y11, which displayed important roles in the binding of CSP2 to DMNT. The results also showed that Y11 is located in the pocket region where CSP2 has a pi-alkyl interaction with DMNT. Meanwhile, comparative and evolutionary analyses indicated that CSP2 shared a high sequence similarity with CSPs of other insect family members such as Sternorrhyncha and Auchenorrhyncha including aphids, whiteflies and planthoppers.

These results suggested that CSP2 likely contributes to mediating responses of B. #link# tabaci to plant volatiles, which may play a pivotal role in its feeding and oviposition preferences. Moreover, these findings could provide key information for exploring efficiency monitoring and integrated pest management strategies of B. tabaci.

To assess whether women with a genetic predisposition to medical conditions known to increase pre-eclampsia risk have an increased risk of pre-eclampsia in pregnancy.

Case-control study.

Pre-eclampsia cases (n=498) and controls (n=1864) in women of European ancestry from five US sites genotyped on a cardiovascular gene-centric array.

Significant single-nucleotide polymorphisms (SNPs) from 21 traits in seven disease categories (cardiovascular, inflammatory/autoimmune, insulin resistance, liver, obesity, renal and thrombophilia) with published genome-wide association studies (GWAS) were used to create a genetic instrument for each trait. Multivariable logistic regression was used to test the association of each continuous scaled genetic instrument with pre-eclampsia. Odds of pre-eclampsia were compared across quartiles of the genetic instrument and evaluated for significance.

Genetic predisposition to medical conditions and relationship with pre-eclampsia.

An increasing burden of risk alleles for elevated diastolic blood pressure (DBP) and increased body mass index (BMI) were associated with an increased risk of pre-eclampsia (DBP, overall OR 1.11, 95%CI 1.01-1.21, P=0.025; BMI, OR 1.10, 95%CI 1.00-1.20, P=0.042), whereas alleles associated with elevated alkaline phosphatase (ALP) were protective (OR 0.89, 95%CI 0.82-0.97, P=0.008), driven primarily by pleiotropic effects of variants in the FADS gene region. The effect of DBP genetic loci was even greater in early-onset pre-eclampsia cases (at <34weeks of gestation, OR 1.30, 95%CI 1.08-1.56, P=0.005). For other traits, there was no evidence of an association.

These results suggest that the underlying genetic architecture of pre-eclampsia may be shared with other disorders, specifically hypertension and obesity.

A genetic predisposition to increased diastolic blood pressure and obesity increases the risk of pre-eclampsia.

The purpose of this study was to assess health-related quality of life (HR-QOL) in anonymous nondirected living liver donors (ND-LLDs). ND-LLDs at 3 centers University of Alberta (n = 12), University of Colorado (n = 12), and University of Southern California (n = 12), were surveyed. Thirty donors (83%) responded to the Donor Quality of Life (USC DQLS) and Short-Form 36 (SF-36). Most respondents (n = 15, 50%) donated their left lateral segment, 27% right lobe, and 23% left lobe. The majority were female (67%) and mean age was 38.9 ± 11.2 years at donation. Median follow-up was 1.1 (interquartile range 0.4-3.3) years. Approximately 37% had previously donated a kidney. Eleven experienced ≥1 postoperative complication, with only 1 Clavien-Dindo IIIb. Most reported minimal impact on school or work performance, all felt positive or neutral about their overall health since donation, and none expressed postdonation regrets. No donor reported impacts on health insurability, and 3 of 4 respondents attempting to purchase life insurance postdonation were successful. ND-LLD SF-36 outcomes were similar to US population norms. link2 Overall, ND-LLDs demonstrated acceptable HR-QOL after donation and are appropriate candidates for partial liver donation. Based on evaluation of donation impact, consideration should be given to postdonation support strategies.

We aim to determine the influence of lower gastrointestinal bleeding (LGIB) on mortality, morbidity, length of hospital stay and resource utilisation in end-stage renal disease (ESRD) patients.

The National Inpatient Sample database (2016 &2017) was used for data analysis using the International Classification of Diseases, Tenth Revision codes to identify the patients with the principal diagnosis of ESRD and LGIB. We assessed the all-cause in-hospital mortality, morbidity, predictors of mortality, length of hospital stay (LOS) and total costs between propensity-matched groups of ESRD patients with LGIB versus ESRD patients.

We identified 2187954 ESRD patients, of whom 242075 has LGIB, and 1945879 were ESRD patients. The in-hospital mortality was higher in ESRD with LGIB (OR 2.5, 95% CI 1.5-2.2; P=.00). ESRD with LGIB has higher odds of mechanical ventilation (OR 1.4, 95% CI 6.4-16.4; P=.00), and shock requiring vasopressor (OR 1.2, 95% CI 4.9-5.4; P=.002). Advanced age (OR 1.02 CI 1.02-1.03 P=.00), anaemia (OR 1.04 CI 1.59-1.91 P=.006), acute coronary syndrome (OR 1.8 CI 1.6-2.1, P=.00), acute respiratory failure (OR 1.29 CI 2.0-2.6, P=.00), mechanical ventilation (OR 1.9, CI 3.5-4.4, P=.00) and sepsis (OR 1.5, CI 4.1-5.08, P=.00) were identified as predictors of mortality in ESRD with LGIB. Mean LOS (10.8±14.9 vs 6.3±8.5, P<.01) and mean total charges (37054 $ vs 18080 $, P<.01) were also higher.

In this propensity-matched analysis, ESRD with LGIB was associated with higher odds of in-hospital mortality, mechanical ventilation and shock requiring vasopressor. Mean LOS and resource utilisation were also higher.

However, acute rejection of the skin is frequently observed and underscores the importance of developing tolerance induction protocols. In this study, we have characterized the skin immune system in VCAs. We demonstrate infiltration of recipient leukocytes, regardless of rejection status, and in tolerant mixed hematopoietic chimeras, the co-existence of these cells with donor leukocytes in the absence of rejection. Here we characterize the dermal T cell and epidermal Langerhans cell components of the skin immune system in our porcine model of VCA tolerance, and the kinetics of cutaneous chimerism in both of these populations in VCAs transplanted to tolerant and nontolerant recipients, as well as in host skin. link3 Furthermore, in biopsies from the first patient to receive a hand transplant in our program, we demonstrate the presence of recipient T cells in the skin of the transplanted limb in the absence of clinical or histological evidence of rejection.

To evaluate the impact of Retzius-sparing robot-assisted radical prostatectomy (posterior approach) on early recovery of urinary continence (UC) compared to the conventional approach (anterior approach) for the treatment of clinically localized prostate cancer (PCa).

A total of 110 consecutive patients with clinically localized PCa were prospectively randomized in a 11 ratio to an anterior group (n = 55) or a posterior group (n = 55). The primary outcome was immediate UC, defined as freedom from any pad use within 1week after removal of the urinary catheter. The UC rate following surgery was also calculated with Kaplan-Meier curves, and the log-rank test was used for statistical comparison. Intra-operative outcomes, pathological data and oncological outcomes, including positive surgical margin (PSM) status and biochemical recurrence-free survival (BCRFS), were also compared between the two groups. The comparison of the two approaches was also analysed in subgroups after risk stratification.

Of the patiey localized PCa, especially for high-risk cases.

The Retzius-sparing approach significantly improved early recovery of UC compared to the conventional approach. Further prospective studies are needed to confirm the benefits of the Retzius-sparing approach for clinically localized PCa, especially for high-risk cases.

The colostomy impact (CI) score is a patient-reported outcome measure assessing reduction in health-related quality of life (HRQL) due to a stoma. The score was originally developed and validated in a cohort of rectal cancer survivors with a permanent colostomy. For the CI score to be applied to patients with a colostomy after surgery for a benign condition it must be validated in this patient group. The aim of this study was to assess construct validity and known groups validity of the CI score in patients with a colostomy after surgery for a benign condition.

In Akti-1/2 -sectional survey among ostomates in the Capital Region of Denmark, patients completed the CI score and the SF-36 v2 questionnaires. Construct validity was assessed by Pearson's correlation coefficients and known groups validity was assessed by t-test when dividing patients into groups of minor or major CI.

The CI score showed a moderate negative correlation with the Physical Component Summary (PCS) of -0.41 and a weak negative correlation with the Mental Component Summary (MCS) of -0.39. The strength of the correlation depended on the underlying condition leading to stoma formation. Differences were significant between the minor and major CI groups in mean PSC and MCS with t-values of 5.32 and 3.86, respectively.

The CI score is a valid instrument for assessing stoma-related impact on HRQL regardless of the underlying condition leading to stoma formation, and the CI score discriminates meaningfully between groups with known differences in stoma-related reduced HRQL.
