    Introduction. Traumatic brain injury is a leading cause of death and disability among children, adolescents. Therefore, analysing outcome predictors and initiating preventive policies may contribute to decreased incidence and better prognosis. Aim. Aim to describe the epidemiologic characteristics, mechanism of injury, radiological findings and also to analyse the determinants of outcome that could help to provide better critical care and also to establish effective preventive policies. Material and Methods. We conducted a prospective study including patients ?18 years admitted to our Neuro-intensive care unit at R.N.T. Medical College ,Udaipur, Rajasthan, India from September 2016 to June 2018.Factors including age, gender ,mode of injury, Glasgow coma score(GCS) at admission ,pupillary size-reaction, radiological findings and their relation to outcome was assessed .Patients were divided into mild, moderate and severe head injury according to GCS. Outcome of patients was assessed by Glasgow outcome scale. For statical Analysis used Chisquare test. Statistical Analysis was carried out using Stata 11.0(College station, Texas, USA) Results. The study comprised of 84 paediatric patients. 44.4%of patients were within 1–5-year age group. The most common cause for trauma was falls and traffic accidents. Patients with mild, moderate and severe head injury were 38.1%, 47.6%and 14.3% respectively. Poor outcome predictors included severity of head injury, pupil size and reaction, midline shift on CT. Conclusion. This study emphasizes increased burden of paediatric brain injury with assessment of predicting factors for more effective critical care of patients and emerging need for effective fall and traffic accidents prevention strategies

    Background. Extradural hematoma of posterior fossa (PFEDH) is less common and there are not many articles about PFEDH. These patients can deteriorate very rapidly due to compression over brainstem. Thus, early identification and immediate intervention can save the lives of these patients.Objective. This study aims to conduct a comprehensive analysis of patients with PFEDH and evaluate the postoperative outcome which may be of help to make further preventive strategies.Methods and Materials. The study included 16 patients admitted with traumatic PFEDH from July 2016 to July 2018 at R.N.T. Medical College & M.B. Groups of Hospital Udaipur, southwestern Rajasthan, India. We have retrospectively reviewed the data. Analysed factors were gender, age, Glasgow Coma Scale (GCS), Noncontrast CT scan findings, associated brain injury, type of intervention, Glasgow Outcome Scale (GOS). GOS was assessed at discharge, at 3 months and 6 months follow-up.Results. Out of a total of 16 patients, 11 were male and 5 were female with age ranging from 05-46 years. 12 patients had GCS 13 -15 at admission and only one of them had GCS < 8. 15 patients underwent surgical intervention. At 6 months follow-up, 12 patients had good recovery GOS is 5.Conclusion. Early detection and immediate evacuation of PFEDHs should be done if causing fourth ventricle, basal cistern or brain stem compression. It may be rapidly fatal due to the expansion of hematoma leading to brainstem compression, tonsillar herniation, and/or obstructive hydrocephalus. Early detection and immediate evacuation lead to a better outcome in these patients

    Emerging Roles and Potential Applications of Non-Coding RNAs in Cervical Cancer

    Cervical cancer (CC) is a preventable disease using proven interventions, specifically prophylactic vaccination, pervasive disease screening, and treatment, but it is still the most frequently diagnosed cancer in women worldwide. Patients with advanced or metastatic CC have a very dismal prognosis and current therapeutic options are very limited. Therefore, understanding the mechanism of metastasis and discovering new therapeutic targets are crucial. New sequencing tools have given a full visualization of the human transcriptome’s composition. Non-coding RNAs (NcRNAs) perform various functions in transcriptional, translational, and post-translational processes through their interactions with proteins, RNA, and even DNA. It has been suggested that ncRNAs act as key regulators of a variety of biological processes, with their expression being tightly controlled under physiological settings. In recent years, and notably in the past decade, significant effort has been made to examine the role of ncRNAs in a variety of human diseases, including cancer. Therefore, shedding light on the functions of ncRNA will aid in our better understanding of CC. In this review, we summarize the emerging roles of ncRNAs in progression, metastasis, therapeutics, chemoresistance, human papillomavirus (HPV) regulation, metabolic reprogramming, diagnosis, and as a prognostic biomarker of CC.We also discussed the role of ncRNA in the tumor microenvironment and tumor immunology, including cancer stem cells (CSCs) in CC.We also address contemporary technologies such as antisense oligonucleotides, CRISPR–Cas9, and exosomes, as well as their potential applications in targeting ncRNAs to manage CC

    Get PDF
    Aims. Traumatic basal ganglia haemorrhage is rare entity but post traumatic bilateral basal ganglia hematoma is even extremely rare and was earlier presented as case reports. Its incidence is about 3% after a closed head injury however, the incidence is higher in post mortem studies. Material & Methods. Out of 1485 head injury patients admitted to our institute from January 2012 to January 2019, there were 9 cases of traumatic bilateral basal ganglia haemorrhage. The incidence of traumatic bilateral basal ganglia Haemorrhage in our series is 0.61% which is very less compared to previous literature. Results. There were 6 males and 3 females; age ranging from 19 to 50 years (average 32 years). Patients with hypertension, history of drugs abuse, history of coagulopathy, with doubtful history of trauma or unknown mode of injury were excluded from the study. The mode of injury in all the patients was road traffic accidents. Average follow up was 9.54 months. Outcome was assessed by Glasgow outcome Score. In 8 out of 9 patients, outcome was good. One patient died. All the nine cases were managed conservatively. Conclusion. We report nine cases from a single institute which to the best of our knowledge is the largest series in world literature. Prognosis is variable and dependent on many factors. The prognosis of TBGH is favourable if not associated with other disorders like hypertension, diabetes mellitus, and coagulation disorders or diffuse axonal injury

    Epigenetic suppression of human telomerase ( hTERT ) is mediated by the metastasis suppressor NME2 in a G-quadruplex–dependent fashion

    Transcriptional activation of the human telomerase reverse transcriptase (hTERT) gene, which remains repressed in adult somatic cells, is critical during tumorigenesis. Several transcription factors and the epigenetic state of the hTERT promoter are known to be important for tight control of hTERT in normal tissues, but the molecular mechanisms leading to hTERT reactivation in cancer are not well-understood. Surprisingly, here we found occupancy of the metastasis suppressor non-metastatic 2 (NME2) within the hTERT core promoter in HT1080 fibrosarcoma cells and HCT116 colon cancer cells and NME2-mediated transcriptional repression of hTERT in these cells. We also report that loss of NME2 results in up-regulated hTERT expression. Mechanistically, additional results indicated that the RE1-silencing transcription factor (REST)–lysine-specific histone demethylase 1 (LSD1) co-repressor complex associates with the hTERT promoter in an NME2-dependent way and that this assembly is required for maintaining repressive chromatin at the hTERT promoter. Interestingly, a G-quadruplex motif at the hTERT promoter was essential for occupancy of NME2 and the REST repressor complex on the hTERT promoter. In light of this mechanistic insight, we studied the effects of G-quadruplex–binding ligands on hTERT expression and observed that several of these ligands repressed hTERT expression. Together, our results support a mechanism of hTERT epigenetic control involving a G-quadruplex promoter motif, which potentially can be targeted by tailored small molecules

    Composition analysis (pick analysis) of waste generated from household : A pilot study in Ujjain city, India

    Get PDF
    Waste segregation is an essential function in improving waste management. Waste segregation not only facilitates recycling and reduces waste going to landfills, rather it can benefit our environment and human in various ways. A pick analysis of waste composition is used to characterize the household waste stream and thus can analyze the segregation rate among the residents. In addition, it can measure the actual waste sorting behaviour at the household/community level. The objective of the study was to assess feasibility of a large-scale waste composition study, identify methodological and operational challenges, and estimate the resources needed to conduct the main waste composition study in order to obtain and get indicative figures about waste generation, composition, and miss-sorted proportions. The study team went door-to-door to collect waste in colour coded bags. We also collected the socio-demographic data of the households. The collected waste was weighed and segregated to analyze the waste composition. The analysis was done among 45 households, and it was found that the per capita waste generation per day is 0.25 kg (0.24 kg from slum and 0.27 kg from non-slum). Challenges identified in conducting waste composition study were lack of standard waste fraction classifications, difficulty in recruitment of personnel to conduct study due to social taboo around waste, challenge in co-coordinating with Ujjain Municipal Corporation waste collection vehicle for collection of waste. 53 household activities were completed in 5 and half hours with INR 24685 (USD 300.5). Pick analysis could be adopted by the Ujjain Municipal Corporation after cost effective analysis to generate precise estimate of waste generation, resource recovery, efficient resource allocation and will help in future interventions and informed policy decision making to improve segregation.Peer reviewe

    Differential cross section measurements for the production of a W boson in association with jets in proton–proton collisions at √s = 7 TeV

    Get PDF
    Measurements are reported of differential cross sections for the production of a W boson, which decays into a muon and a neutrino, in association with jets, as a function of several variables, including the transverse momenta (pT) and pseudorapidities of the four leading jets, the scalar sum of jet transverse momenta (HT), and the difference in azimuthal angle between the directions of each jet and the muon. The data sample of pp collisions at a centre-of-mass energy of 7 TeV was collected with the CMS detector at the LHC and corresponds to an integrated luminosity of 5.0 fb[superscript −1]. The measured cross sections are compared to predictions from Monte Carlo generators, MadGraph + pythia and sherpa, and to next-to-leading-order calculations from BlackHat + sherpa. The differential cross sections are found to be in agreement with the predictions, apart from the pT distributions of the leading jets at high pT values, the distributions of the HT at high-HT and low jet multiplicity, and the distribution of the difference in azimuthal angle between the leading jet and the muon at low values.United States.

    Risk portfolio on modern finance has become increasingly technical, requiring the use of sophisticated mathematical tools in both research and practice. Since companies cannot insure themselves completely against risk, as human incompetence in predicting the future precisely that written in Al-Quran surah Luqman verse 34, they have to manage it to yield an optimal portfolio. The objective here is to minimize the variance among all portfolios, or alternatively, to maximize expected return among all portfolios that has at least a certain expected return. Furthermore, this study focuses on optimizing risk portfolio so called Markowitz MVO (Mean-Variance Optimization). Some theoretical frameworks for analysis are arithmetic mean, geometric mean, variance, covariance, linear programming, and quadratic programming. Moreover, finding a minimum variance portfolio produces a convex quadratic programming, that is minimizing the objective function ðð¥with constraintsð ð 𥠥 ðandð´ð¥ = ð. The outcome of this research is the solution of optimal risk portofolio in some investments that could be finished smoothly using MATLAB R2007b software together with its graphic analysis
