Earliness, yield and bulb parameters of hardneck garlic (Allium sativum L.) as influenced by leaf knotting and scape removal in north Indian plains

The present study was conducted during Rabi 2012–13 and 2013–14 to estimate the effect of scape removal, leaf knotting 4 weeks before harvest and leaf knotting 2 weeks before harvest on earliness, yield and bulb parameters of hardneck garlic cultivar ‘PG-17’ in north western plains of India. The removal of scapes has no effect on reduction in days to maturity, equatorial diameter of bulb, bulb weight, number of cloves per bulb and cured bulb yield as compared to control. The knotting of leaves 4 and 2 weeks before harvest advanced maturity by 12 and 6 days, respectively, over control. Leaf knotting 4 weeks before harvest significantly decreased equatorial diameter of bulb, bulb weight and cured bulb yield, whereas, leaf knotting 2 weeks before harvest caused non-significant reduction in equatorial diameter of bulb, bulb weight, number of cloves per bulb, 50-clove weight and cured bulb yield as compared to control. It is therefore advisable that the practice of leaf knotting may be omitted to save labour charges, whereas the practice of scape removal in hardneck garlic cultivars should be exercised only after studying the response of that particular cultivar to scape removal. &nbsp

MicroRNA-383 located in frequently deleted chromosomal locus 8p22 regulates CD44 in prostate cancer.

A major genomic alteration in prostate cancer (PCa) is frequent loss of chromosome (chr) 8p with a common region of loss of heterozygosity (LOH) at chr8p22 locus. Genomic studies implicate this locus in the initiation of clinically significant PCa and with progression to metastatic disease. However, the genes within this region have not been fully characterized to date. Here we demonstrate for the first time that a microRNA component of this region-miR-383-is frequently downregulated in prostate cancer, has a critical role in determining tumor-initiating potential and is involved in prostate cancer metastasis via direct regulation of CD44, a ubiquitous marker of PCa tumor-initiating cells (TICs)/stem cells. Expression analyses of miR-383 in PCa clinical tissues established that low miR-383 expression is associated with poor prognosis. Functional data suggest that miR-383 regulates PCa tumor-initiating/stem-like cells via CD44 regulation. Ectopic expression of miR-383 inhibited tumor-initiating capacity of CD44+ PCa cells. Also, 'anti-metastatic' effects of ectopic miR-383 expression were observed in a PCa experimental metastasis model. In view of our results, we propose that frequent loss of miR-383 at chr8p22 region leads to tumor initiation and prostate cancer metastasis. Thus, we have identified a novel finding that associates a long observed genomic alteration to PCa stemness and metastasis. Our data suggest that restoration of miR-383 expression may be an effective therapeutic modality against PCa. Importantly, we identified miR-383 as a novel PCa tissue diagnostic biomarker with a potential that outperforms that of serum PSA

Predictors of health-related quality of life after cardiac surgery: a systematic review

Background Health-related quality of life (HRQoL) is important in determining surgical success, particularly from the patients’ perspective. Aims To identify predictors for HRQoL outcome after cardiac surgery in order to identify potentially modifiable factors where interventions to improve patient outcomes could be targeted. Methods Electronic databases (including MEDLINE, CINAHL, Embase) were searched between January 2001 and December 2020 for studies determining predictors of HRQoL (using a recognised and validated tool) in adult patients undergoing cardiac surgery. Data extraction and quality assessments were undertaken and data was summarised using descriptive statistics and narrative synthesis, as appropriate. Results Overall, 3924 papers were screened with 41 papers included in the review. Considerable methodological heterogeneity between studies was observed. Most were single-centre (75.6%) prospective observational studies (73.2%) conducted in patients undergoing coronary artery bypass graft (CABG) (n = 51.2%) using a version of the SF-36 (n = 63.4%). Overall, 103 independent predictors (62 pre-operative, five intra-operative and 36 post-operative) were identified, where 34 (33.0%) were reported in more than one study. Potential pre-operative modifiable predictors include alcohol use, BMI/weight, depression, pre-operative quality of life and smoking while in the post-operative period pain and strategies to reduce post-operative complications and intensive care and hospital length of stay are potential therapeutic targets. Conclusion Despite a lack of consistency across studies, several potentially modifiable predictors were identified that could be targeted in interventions to improve patient or treatment outcomes. This may contribute to delivering more person-centred care involving shared decision-making to improve patient HRQoL after cardiac surgery

Pathways to Belonging and Engagement: Testing a Tailored Social Belonging Intervention for University Students

Background Prominent theories of motivation suggest that belonging plays a critical role in student success (Connell & Wellborn, 1991). Social-belonging interventions have been shown to improve student belonging, well-being, engagement, and more—especially those from traditionally disadvantaged backgrounds (Walton & Brady, 2017). The current study aimed to explore the effects of a tailored social-belonging intervention delivered in introductory classes at VCU on students’ belonging, engagement, persistence, and achievement. Methods A diverse sample of first-year undergraduate students at VCU participated. To create authentic intervention materials, we collaborated with a diverse group of upper-level undergraduate student researchers who wrote narratives to present vivid stories of how they personally experienced and overcame struggles to belong. Prior to and following the intervention, students completed a survey that assessed student belonging, engagement, and social and academic fit. We also collected student demographics, achievement, and additional data from institutional records. Results Following the implementation of the belonging intervention, data was collected on students’ sense of belonging, their social and academic fit at the university, and other related outcomes. While most students felt as though they belonged at VCU and had the potential to succeed, there were still some students who worried whether they belonged in college. Conclusions From students’ responses, faculty and advisors of first-year students were given an overview on students’ current states of belonging at VCU. As an implication for future research, we argue that including diverse upper-level students as fellow researchers in this work strengthens the authenticity and effectiveness of the belonging intervention.https://scholarscompass.vcu.edu/gradposters/1171/thumbnail.jp

The Burden of Brain Hypoxia and Optimal Mean Arterial Pressure in Patients With Hypoxic Ischemic Brain Injury After Cardiac Arrest.

OBJECTIVES: In patients at risk of hypoxic ischemic brain injury following cardiac arrest, we sought to: 1) characterize brain oxygenation and determine the prevalence of brain hypoxia, 2) characterize autoregulation using the pressure reactivity index and identify the optimal mean arterial pressure, and 3) assess the relationship between optimal mean arterial pressure and brain tissue oxygenation. DESIGN: Prospective interventional study. SETTING: Quaternary ICU. PATIENTS: Adult patients with return of spontaneous circulation greater than 10 minutes and a postresuscitation Glasgow Coma Scale score under 9 within 72 hours of cardiac arrest. INTERVENTIONS: All patients underwent multimodal neuromonitoring which included: 1) brain tissue oxygenation, 2) intracranial pressure, 3) jugular venous continuous oximetry, 4) regional saturation of oxygen using near-infrared spectroscopy, and 5) pressure reactivity index-based determination of optimal mean arterial pressure, lower and upper limit of autoregulation. We additionally collected mean arterial pressure, end-tidal CO2, and temperature. All data were captured at 300 Hz using ICM+ (Cambridge Enterprise, Cambridge, United Kingdom) brain monitoring software. MEASUREMENTS AND MAIN RESULTS: Ten patients (7 males) were included with a median age 47 (range 20-71) and return to spontaneous circulation 22 minutes (12-36 min). The median duration of monitoring was 47 hours (15-88 hr), and median duration from cardiac arrest to inclusion was 15 hours (6-44 hr). The mean brain tissue oxygenation was 23 mm Hg (SD 8 mm Hg), and the mean percentage of time with a brain tissue oxygenation below 20 mm Hg was 38% (6-100%). The mean pressure reactivity index was 0.23 (0.27), and the percentage of time with a pressure reactivity index greater than 0.3 was 50% (12-91%). The mean optimal mean arterial pressure, lower and upper of autoregulation were 89 mm Hg (11), 82 mm Hg (8), and 96 mm Hg (9), respectively. There was marked between-patient variability in the relationship between mean arterial pressure and indices of brain oxygenation. As the patients' actual mean arterial pressure approached optimal mean arterial pressure, brain tissue oxygenation increased (p < 0.001). This positive relationship did not persist when the actual mean arterial pressure was above optimal mean arterial pressure. CONCLUSIONS: Episodes of brain hypoxia in hypoxic ischemic brain injury are frequent, and perfusion within proximity of optimal mean arterial pressure is associated with increased brain tissue oxygenation. Pressure reactivity index can yield optimal mean arterial pressure, lower and upper limit of autoregulation in patients following cardiac arrest

General insurance marketing: a review and future research agenda

The financial services sector is a huge and diverse industry comprising many different forms of organisations and product offerings. Yet, a review of past papers in the Journal of Financial Services Marketing (JFSM) reveals a heavy bias towards articles on banking, to the neglect of other equally important financial services categories. The purpose of this paper is to address this imbalance and to call for more research to be conducted in a wider range of financial services categories. In particular, general insurance is singled out as a category worthy of further research. Looking to the past, this paper reviews research published to-date on general insurance in the JFSM to establish a benchmark and explore theoretical contributions. Attention is then turned to the future to identify a research agenda for the general insurance sector going forward. 5 important themes are identified: trust, transparency and simplification, technology, HNW and Takaful

Update on cervical disc arthroplasty: where are we and where are we going?

Despite the very good results of anterior cervical discectomy and fusion, there are concerns of adjacent level degeneration. For this reason, interest has grown in the potential for motion sparing alternatives. Cervical disc arthroplasty is thus evolving as a potential alternative to fusion. Specific design characteristic and implants will be reviewed and outcomes summarized
