Assessment of Ponseti technique of manipulation and serial casting in idiopathic clubfoot
Background: Congenital talipes equinovarus is one of the commonest congenital foot deformities. Ponseti technique of treatment of clubfoot has gained popularity in the last few decades. Feet treated by Ponseti technique are supple, flexible and pain free. We have treated congenital idiopathic clubfoot with Ponseti technique at our institute and present our results.Methods: Forty eight feet in thirty children with clubfoot were treated by Ponseti technique in our institute. The study was conducted from December 2013 to December 2015. Parents were counselled regarding treatment protocol and maintenance with bracing was closely monitored. Each child was followed up for a minimum of six months. Pirani score was used to objectively document progress of treatment.Results: The average number of casts required for complete correction was 6.6. 38% feet required tendoachilles tenotomy. Higher the initial Pirani score, more number of casts were required to achieve full correction. Number of casts needed for complete correction did not correlate to time of presentation.Conclusions: Ponseti method is very effective in correcting congenital idiopathic clubfoot deformity. It’s easy to learn, is inexpensive and can completely correct the deformity. In developing nations, well trained Orthopaedic surgeons can treat these children effectively and decrease disabled population.
Phytoextraction of cadmium and lead by three vegetable-crop plants
Phytoextraction, is an effective and promising means to cure soil contamination with heavy metals. The present study investigates the ability of three vegetables plants for removal of heavy metals from the contaminated soil and metal mobilization to different plant parts. The three plants selected for the study, Momordica charantia, Vigna unguiculata and Solanum melongena were grown for 90 days in soils artificially contaminated with cadmium (Cd) and lead (Pb) (50mg metal/kg of soil). The concentrations of the two metals were observed to be higher in roots of M. charantia and V. unguiculata than in soil, but root Pb level of S. melongena was slightly lower than that of soil after 90 days. Translocation potential of the heavy metals indicated higher accumulation of Cd in roots of M. charantia and S. melongena than in leaves while the pattern was completely opposite in V. unguiculata. Lead accumulation was higher in roots than in leaves for all the three plant species studied. The Translocation Factor (TF) of Cd for the three plants was in the range of 1.16 to 2.29 whereas, TF values of Pb remained <1, indicating that only small amount of Pb was translocated from roots to aerial parts.
Impact of Quran in treatment of the psychological disorder and spiritual illness
This paper studies the effect of Quranic therapy on psychological diseases and spiritual diseases. The experiments have been conducted on a random sample with 121 patients from both genders. The procedures that have been followed were different sessions with the patients, who were given some verses from the Holy Quran to listen within a specific period of time. After that, each patient was given a remedy program. This study aimed to measure the effectiveness and responsiveness of patients to receive treatment through Quran. This study highlighted the employment of a quantitative research, which achieved its objective through validity and reliability. The results of the effectiveness factor came after ability and willingness and gave a result of 92.6% for those who support the contention that the Quran has a significant healing influence. Also, some of the patients who regularly attended Quranic therapy sessions have been successfully cured, 81.8% of the sample believe that Quranic therapy sessions support their health needs. This study has empirically proved that the sound of the Holy Quran is an effective treatment for those who suffer from spiritual and psychological issues. Folk medicine and other traditional methods of treatment are important field of study that require further investigation. The study also illustrates that it's highly important for patient to have confidence in his doctor or healer. Furthermore, our results show that the ability and willingness positively and significantly are related to the effectiveness and responsiveness, also effectiveness positively and significantly related to the responsiveness. Therefore, the patients satisfied to receive treatment through Quran and they have the ability and willingness to do so as they believe that Quran is an essential part of their life
Finishing the euchromatic sequence of the human genome
The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead
Safety and efficacy of the ChAdOx1 nCoV-19 vaccine (AZD1222) against SARS-CoV-2: an interim analysis of four randomised controlled trials in Brazil, South Africa, and the UK.
BACKGROUND: A safe and efficacious vaccine against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), if deployed with high coverage, could contribute to the control of the COVID-19 pandemic. We evaluated the safety and efficacy of the ChAdOx1 nCoV-19 vaccine in a pooled interim analysis of four trials. METHODS: This analysis includes data from four ongoing blinded, randomised, controlled trials done across the UK, Brazil, and South Africa. Participants aged 18 years and older were randomly assigned (1:1) to ChAdOx1 nCoV-19 vaccine or control (meningococcal group A, C, W, and Y conjugate vaccine or saline). Participants in the ChAdOx1 nCoV-19 group received two doses containing 5 × 1010 viral particles (standard dose; SD/SD cohort); a subset in the UK trial received a half dose as their first dose (low dose) and a standard dose as their second dose (LD/SD cohort). The primary efficacy analysis included symptomatic COVID-19 in seronegative participants with a nucleic acid amplification test-positive swab more than 14 days after a second dose of vaccine. Participants were analysed according to treatment received, with data cutoff on Nov 4, 2020. Vaccine efficacy was calculated as 1 - relative risk derived from a robust Poisson regression model adjusted for age. Studies are registered at ISRCTN89951424 and ClinicalTrials.gov, NCT04324606, NCT04400838, and NCT04444674. FINDINGS: Between April 23 and Nov 4, 2020, 23 848 participants were enrolled and 11 636 participants (7548 in the UK, 4088 in Brazil) were included in the interim primary efficacy analysis. In participants who received two standard doses, vaccine efficacy was 62·1% (95% CI 41·0-75·7; 27 [0·6%] of 4440 in the ChAdOx1 nCoV-19 group vs71 [1·6%] of 4455 in the control group) and in participants who received a low dose followed by a standard dose, efficacy was 90·0% (67·4-97·0; three [0·2%] of 1367 vs 30 [2·2%] of 1374; pinteraction=0·010). Overall vaccine efficacy across both groups was 70·4% (95·8% CI 54·8-80·6; 30 [0·5%] of 5807 vs 101 [1·7%] of 5829). From 21 days after the first dose, there were ten cases hospitalised for COVID-19, all in the control arm; two were classified as severe COVID-19, including one death. There were 74 341 person-months of safety follow-up (median 3·4 months, IQR 1·3-4·8): 175 severe adverse events occurred in 168 participants, 84 events in the ChAdOx1 nCoV-19 group and 91 in the control group. Three events were classified as possibly related to a vaccine: one in the ChAdOx1 nCoV-19 group, one in the control group, and one in a participant who remains masked to group allocation. INTERPRETATION: ChAdOx1 nCoV-19 has an acceptable safety profile and has been found to be efficacious against symptomatic COVID-19 in this interim analysis of ongoing clinical trials.

Modeling of the in-pipe inspection robot: a comprehensive review
The in-pipe inspection robotic system is crucial in examining the inside of a pipe without compromising its structural safety. The in-pipe inspection robotic system is a promising alternative to conventional methods of x-ray inspection and visual inspection. Despite the ongoing investigation, the effectiveness of the in-pipe inspection robotic system, particularly regarding the mathematical modeling of the system design, still needs to be improved. The in-pipe inspection robot which is normally equipped with a camera or non-destructive testing (NDT) equipment moves inside the pipeline to conduct a pipe integrity assessment. The main problem during an inspection is the restricted maneuverability of the robot due to geometric changes in the pipe. This can be overcome by designing a proper mathematical model to develop an effective inspection robotic system. Therefore, this paper provides a systematic review of different modeling types of the in-pipe inspection robotic systems, including the assessment of the kinematic and dynamic mathematical models for the system. This review paper covers in-pipe inspection robotic systems with several driving mechanisms such as fluid-driven, wheeled mobile drive (WMD), screw or helical drive, legged and biomimetic drives
Linear quadratic regulator based control device for active suspension system with enhanced vehicle ride comfort
The suspension system is required in an automobile in order to absorb shock that comes from various type of disturbances such as irregular road profile, engine vibrations and wheel. Besides, the suspension plays an important part in enhancing the passenger ride comfort. The suspension will make sure that the tire is always contacted with the road for a better grip and braking. Conventionally, passive suspension has been used in car manufacturing that leads to huge vibrations that affect the ride quality. This is because ride comfort of passengers gets affected by overshoot and settling time of vehicle under vibration. Therefore, a good controller design is required to minimize the vibrations. In this research, an active suspension of quarter car model that considers only vertical movement is utilized in the suspension system. This paper presents a Linear Quadratic Regulator (LQR) method to enhance the vehicle ride comfort towards the vibration of the suspension system. The control design approach is then compared with the classical control which is the Proportional Integral Derivative (PID) that is set as a benchmark control. The results for both controllers are evaluated through simulations in MATLAB and Simulink Software. Other than using the passenger vehicle parameters, the parameters of bus are also tested into the system to investigate the vehicle performance by taking the bumps and road pavements as road disturbances. The results obtained from the simulations show that the responses of the quadratic based approach give the significant improvement in minimizing the vibration and fast settling time compared to passive and PID control
