Effects of decaying leaf litter and inorganic fertilizer on growth and development of maize (Zea mays L.)

The effects of decaying leaf litter of Tithonia diversifolia and Vernonia amygdalina as organic fertilizer, inorganic fertilizer (NPK 15-15-15) and their combination effects on the growth and development of maize were studied in a screen house. Twenty-four experimental bags filled with 20 kg of loamy soil were laid out in a completely randomized design with six treatments and four replications for each treatment which included: 250 g of decaying leaves of T. diversifolia as mulch (T1), 250 g of decaying leaves of V. amygdalina (T2), 1.52 g of NPK (inorganic) fertilizer (T3), a mixture of 250 g of decaying leaves of T. diversifolia and 1.52 g of NPK 15-15-15 fertilizer (T4), a mixture of V. amygdalina and 1.52 g of NPK 15-15-15 fertilizer (T5) and control (T6). The significant growth as well as maize yields were obtained from T3 treated maize seedlings, and this was closely followed by T4 treated seedlings. The study showed that the decaying leaf litter as an organic fertilizer in maize production in a screen house conditions did not give better yield than NPK treatment alone

Current diversity of aquatic macrophytes in nigerian freshwater ecosystem

In Nigerian inland waters, eight aquatic plants have been incriminated as weeds. From the current study, the most prevalent of these weeds are water hyacinth and cattail plants. These aquatic weeds, once it invades a water body, not only disrupts the ecology of the systems but adversely affects the sociological, cultural and economic realities of the local communities within the area, especially the artisanal fisher folks. This paper showcases aquatic weeds distribution country wide based on its hydrological areas as well as their controlling methods. These methods, when employed in aquatic weed infested water bodies, will manifestly contribute to the success of approaches geared to solving aquatic weed problems

Cost-effectiveness of implementing a digital psychosocial intervention for patients with psychotic spectrum disorders in low- and middle-income countries in Southeast Europe: Economic evaluation alongside a cluster randomised trial

BACKGROUND: DIALOG+ is a digital psychosocial intervention aimed at making routine meetings between patients and clinicians therapeutically effective. This study aimed to evaluate the cost-effectiveness of implementing DIALOG+ treatment for patients with psychotic disorders in five low- and middle-income countries in Southeast Europe alongside a cluster randomised trial. METHODS: Resource use and quality of life data were collected alongside the multi-country cluster randomised trial of 468 participants with psychotic disorders. Due to COVID-19 interruptions of the trial’s original 12-month intervention period, adjusted costs and quality-adjusted life years (QALYs) were estimated at the participant level using a mixed-effects model over the first 6 months only. We estimated the incremental cost-effectiveness ratio (ICER) with uncertainty presented using a cost-effectiveness plane and a cost-effectiveness acceptability curve. Seven sensitivity analyses were conducted to check the robustness of the findings. RESULTS: The average cost of delivering DIALOG+ was €91.11 per participant. DIALOG+ was associated with an incremental health gain of 0.0032 QALYs (95% CI –0.0015, 0.0079), incremental costs of €84.17 (95% CI –8.18, 176.52), and an estimated ICER of €26,347.61. The probability of DIALOG+ being cost-effective against three times the weighted gross domestic product (GDP) per capita for the five participating countries was 18.9%. CONCLUSION: Evidence from the cost-effectiveness analyses in this study suggested that DIALOG+ involved relatively low costs. However, it is not likely to be cost-effective in the five participating countries compared with standard care against a willingness-to-pay threshold of three times the weighted GDP per capita per QALY gained

Effectiveness of the third wave cognitive behavior therapy for peripartum depression treatment – a systematic review

Introduction: To investigate the effectiveness of third-wave cognitive behavior therapies in the treatment of peripartum depression. Method: A systematic review of the effectiveness of psychological interventions in treating peripartum depression focus on the Third Wave has been conducted. The electronic databases MEDLINE, PsycINFO, Web of Science and Clinical Trials were searched, using a combination of different search terms. Data were independently extracted by two authors and a synthesis of the results was offered. Methodological quality was assessed by three authors, using ROBE-2 and MINORS. Search date was conducted in February 2022 and the search was re-run in November 2022 for new entries. Findings: Six papers were included and reported, focused on, the effectiveness of Third Wave approach interventions in reducing depressive symptoms. Papers included the following intervention approaches: Behavioral intervention (n = 2), Mindfulness (n = 2), Dialectical Behavior Therapy (n = 1) and Acceptance and Commitment Therapy (n = 1). All six papers were consistent in that interventions lead to a decrease in depression symptoms. However, risk of bias evaluation showed that all were critical low, but one paper was high quality. Conclusion and implications for practice and research: Systematic review showed that third-wave approaches are promising in effectiveness to reduce depression symptoms in peripartum women. However, more high-quality studies with follow-up are needed.info:eu-repo/semantics/publishedVersio

Structure Dependent Conductivity of Ultrathin ZnO Films

Zinc oxide lms dedicated for hybrid organic/inorganic devices have been studied. The lms were grown at low temperature (100 • C, 130 • C and 200 • C) required for deposition on thermally unstable organic substrates. ZnO layers were obtained in atomic layer deposition processes with very short purging times in order to shift a structure of the lms from polycrystalline towards amorphous one. The correlation between atomic layer deposition growth parameters, a structural quality and electrical properties of ZnO lms was determined

A pathological fracture and a solitary mass in the right clavicle: an unusual first presentation of HCC and the role of immunohistochemistry

<p>Absrtract</p> <p>Hepatocellular carcinoma (HCC) is an aggressive malignant tumor that occurs throughout the world. Μetastases from hepatocellular carcinoma (HCC) were generally considered to be rare in the past, because the carcinoma had an aggressive clinical course. In our era, has been reported that extra-hepatic metastases occur in 13.5%-41.7% of HCC patients and this is considered as terminal-stage cancer. The prognosis for patients at this stage continues to be poor due to limited effective treatment. The common sites of extrahepatic metastases in patients with HCC are the lungs, regional lymph nodes, kidney, bone marrow and adrenals. We present here an extremely infrequent case of a patient, without known liver disease, in which the presenting symptom was a pathological-in retrospect-fracture of his right clavicle which wasn't properly evaluated, until he presented a bulky mass in the region 6 months later. For our patient, the added diagnostic difficulty alongside the unknown liver disease, has been that the clavicular metastases was the first presentation of any metastatic disease, rather than the more common sites of HCC spread to adjacent lung or lymph nodes.</p

Simulation Modelling in Ophthalmology : Application to Cost Effectiveness of Ranibizumab and Aflibercept for the Treatment of Wet Age-Related Macular Degeneration in the United Kingdom

Previously developed models in ophthalmology have generally used a Markovian structure. There are a number of limitations with this approach, most notably the ability to base patient outcomes on best-corrected visual acuity (BCVA) in both eyes, which may be overcome using a different modelling structure. Simulation modelling allows for this to be modelled more precisely, and therefore may provide more accurate and relevant estimates of the cost effectiveness of ophthalmology interventions

International meta-analysis of PTSD genome-wide association studies identifies sex- and ancestry-specific genetic risk loci.

The risk of posttraumatic stress disorder (PTSD) following trauma is heritable, but robust common variants have yet to be identified. In a multi-ethnic cohort including over 30,000 PTSD cases and 170,000 controls we conduct a genome-wide association study of PTSD. We demonstrate SNP-based heritability estimates of 5-20%, varying by sex. Three genome-wide significant loci are identified, 2 in European and 1 in African-ancestry analyses. Analyses stratified by sex implicate 3 additional loci in men. Along with other novel genes and non-coding RNAs, a Parkinson's disease gene involved in dopamine regulation, PARK2, is associated with PTSD. Finally, we demonstrate that polygenic risk for PTSD is significantly predictive of re-experiencing symptoms in the Million Veteran Program dataset, although specific loci did not replicate. These results demonstrate the role of genetic variation in the biology of risk for PTSD and highlight the necessity of conducting sex-stratified analyses and expanding GWAS beyond European ancestry populations

p53-paralog DNp73 oncogene is repressed by IFNα/STAT2 through the recruitment of the Ezh2 polycomb group transcriptional repressor

The DNp73 proteins act as trans-repressors of p53 and p73-dependent transcription and exert both anti-apoptotic activity and pro-proliferative activity. DNp73s are frequently up-regulated in a variety of human cancers, including human hepatocellular carcinomas (HCCs). Increased levels of DNp73 proteins confer to HCC cells resistance to apoptosis and, irrespective to p53 status, a chemoresistant phenotype. Here, we show that interferon (IFN)α down-regulates DNp73 expression in primary human hepatocytes (PHHs) and HCC cell lines. IFNα has been used as pro-apoptotic agent in the treatment of malignancies and there is increasing evidence of IFNα effectiveness in HCC treatment and prevention of recurrence. The precise mechanisms by which class I IFNs exert their anti-proliferative and anti-tumor activity remain unclear. IFNα binding to its receptor activates multiple intracellular signaling cascades regulating the transcription of numerous direct target genes through the recruitment of a complex comprising of STAT1, STAT2 and IFN regulatory factor (IRF)9 to their promoters. We found that, in response to IFNα, the P2p73 promoter undergoes substantial chromatin remodeling. Histone deacetylases (HDACs) replace histone acetyl transferases. STAT2 is recruited onto the endogenous P2p73 promoter together with the polycomb group protein Ezh2, leading to increased H3K27 methylation and transcriptional repression. The reduction of DNp73 levels by IFNα is paralleled by an increased susceptibility to IFNα-triggered apoptosis of Huh7 hepatoma cells. Our results show, for the first time, that IFN-stimulated gene factor 3 recruitment may serve both in activating and repressing gene expression and identify the down-regulation of DNp73 as an additional mechanism to counteract the chemoresistance of liver cancer cells
