ATMOSPHERIC CO2 GAS AND TEMPERATURE MEASUREMENT ROBOT
In the age of industrial revolution the atmosphere is disturbed by the human acts one of which is the global warming, a major threat of this century. Thus in order to control these adverse effects an monitoring of atmospheric CO2 and temperature robotic system is developed the system to collect data through various sensors. It gives a review of these systems based on existing technologies and also proposes an economical and generic automatic environment pollution control system based on wireless sensors with GSM for environment pollution control system controller and remote monitoring system. This system has simpler features of low cost and effective with less power consumption using sensors for remote monitoring and controlling devices which are controlled via SMS using a GSM module.
The system informs user about any abnormal conditions like temperature rise, even concentration of CO2 via SMS from the GSM module to the higher authority mobile and actions are taken accordingly by the authority personnel. In future, the industry will be able to monitor and control the parameter by GSM technologies, and to provide safety and security for humans
Safety and feasibility of early single-dose mitomycin C bladder instillation after robot-assisted radical nephroureterectomy
Objectives:
To assess the safety and feasibility of early singleâdose mitomycin C (MMC) bladder instillation after robotâassisted radical nephroureterectomy (RARNU) at a tertiary kidney cancer centre. RARNU with bladder cuff excision and subsequent MMC bladder instillation to reduce recurrence risk is the âgold standardâ for highârisk upper urinary tract urothelial carcinoma (UUTUC). We adapted a RARNU technique with precise distal ureteric dissection, bladder cuff excision and watertight bladder closure.
Patients and Methods:
We retrospectively reviewed all patients undergoing RARNU for UUTUC at our centre performed as a standardised transperitoneal procedure comprising of: bladder cuff excision, twoâlayer watertight closure and intraoperative bladder leak test; without reâdocking/reâpositioning of the robotic surgical system. Patient demographics, the timing of MMC instillation, adverse events (surgical and potentially MMCârelated) and length of stay (LOS) were assessed according to the ClavienâDindo classification.
Results:
A total of 69 patients underwent a RARNU with instillation of MMC. The median (interquartile range [IQR]) age was 70 (62â78) years. The median (IQR) day of MMC instillation was 2 (1â3) days and the median (IQR) LOS was 2 (2â4) days, with urethral catheter removal on day of discharge in all cases. Only Grade I ClavienâDindo complications occurred in seven patients (10%); five had ileus, one a wound infection and one a selfâlimiting delirium, all managed conservatively. No adverse events potentially related to MMC instillation were noted within 30 days postoperatively.
Conclusion:
The use of intravesical MMC instillation given in the immediate postoperative period appears feasible and safe in patients undergoing RARNU with intraoperative confirmation of a waterâtight closure ensuring early catheterâfree discharge, with no significant adverse events. The potential reduction in intravesical recurrence in patients receiving early MMC needs to be assessed with longitudinal followâup studies
Robot-assisted surgery in horseshoe kidneys: A safety and feasibility multi-centre case series
OBJECTIVE: We assessed the safety and feasibility of minimally invasive robot-assisted surgery for horseshoe kidney (HSK). METHOD: A prospectively maintained data set for consecutive patients undergoing robotic kidney surgery was reviewed for patients with HSK. Cases were performed by experienced robotic surgeons, across two high-volume centres between 2016 and 2020. RESULTS: A prospectively maintained data set for consecutive patients undergoing robotic kidney surgery was reviewed for patients with HSK. Cases were performed by experienced robotic surgeons, across two high-volume centres between 2016 and 2020. CONCLUSION: We report one the largest series of robot-assisted surgery on HSK. Robotic surgery is safe and feasible for HSK in centralised high-volume centres with acceptable perioperative outcomes. Established benefits of minimally invasive surgery, such as reduced LOS and low complication rates, were demonstrated. LEVEL OF EVIDENCE: 4
Interactive virtual 3D image reconstruction to assist renal surgery in patients with fusion anomalies of the kidney
Objective: Renal fusion anomalies are rare and usually present as horseshoe kidneys or crossed fusion ectopia. The complex renal anatomy seen in patients with these anomalies can present a challenge. Pre-operative planning is therefore paramount in the surgical management of these cases. Herein we report the use of interactive virtual three-dimensional (3D) reconstruction to aid renal surgery in patients with fusion anomalies of the kidney. / Materials and Methods: A total of seven cases were performed between May 2016 and October 2020. 3D reconstruction was rendered by Innersight Labs using pre-operative computed tomography (CT) scans. / Results: Five patients had malignant disease and two patients had benign pathology. Robotic and open operations were performed in four and three patients, respectively. / Conclusion: The use of 3D reconstruction in the cases reported in this series allowed for the identification of variations in renal vasculature, and this informed the choice of operative approach. / Oxford Centre for Evidence-Based Medicine Evidence Level: 4
HDBStat!: A platform-independent software suite for statistical analysis of high dimensional biology data
BACKGROUND: Many efforts in microarray data analysis are focused on providing tools and methods for the qualitative analysis of microarray data. HDBStat! (High-Dimensional Biology-Statistics) is a software package designed for analysis of high dimensional biology data such as microarray data. It was initially developed for the analysis of microarray gene expression data, but it can also be used for some applications in proteomics and other aspects of genomics. HDBStat! provides statisticians and biologists a flexible and easy-to-use interface to analyze complex microarray data using a variety of methods for data preprocessing, quality control analysis and hypothesis testing. RESULTS: Results generated from data preprocessing methods, quality control analysis and hypothesis testing methods are output in the form of Excel CSV tables, graphs and an Html report summarizing data analysis. CONCLUSION: HDBStat! is a platform-independent software that is freely available to academic institutions and non-profit organizations. It can be downloaded from our website
Effect of supplementation of differentially treated banana inflorescence on intestinal morphology in broiler birds
A study was conducted on 96 Vencobb 430, day-old broiler chicks to evaluate the effect of
steam treatment on banana inflorescence supplementation as prebiotic on intestinal morphology.
The birds were randomly assigned into three treatment groups having four replicates with eight
birds per replicate and assigned control diet, formulated in accordance with BIS recommendation
to control (T1) group and with supplementation of 0.5% dried banana inflorescence (T2 group) or
0.5% steam treated banana inflorescence (T3 group). After 42 days of feeding trial, the live weight
was significantly higher in T3 and T2 than control. Two birds from each replicate were sacrificed
to study the intestinal morphometry and pH. The weight of intestine varied significantly (p<0.01)
between the treatments and was higher in T3 while the per cent of intestinal weight did not differ
significantly. Intestinal morphometry revealed that the villus height was significantly (p<0.01)
higher in duodenum, jejunum, and caecum in T3 and ileum in T2. The crypt depth was significantly
(p<0.01) higher in jejunum, ileum and caeca in T3 and T2 in duodenum. Caecal crypt depth showed
significantly (p< 0.01) low value in T2. Ileal crypt depth ratio was significantly (p<0.01) higher in T2
while the caecum crypt depth was significantly(p<0.01) high in T3. It is concluded that banana
inflorescence influenced the gut morphometry in broilers
Growth and renal function dynamics of renal oncocytomas on active surveillance
OBJECTIVES:
To study the natural history of renal oncocytomas and address indications for intervention by determining how growth is associated with renal function over time, the reasons for surgery and ablation, and disease-specific survival.
PATIENTS AND METHODS:
The study was conducted in a retrospective cohort of consecutive patients with renal oncocytoma on active surveillance reviewed at the Specialist Centre for Kidney Cancer at the Royal Free London NHS Foundation Trust (2012 to 2019). Comparison between groups was performed using MannâWhitney U-tests and chi-squared tests. A mixed-effects model with a random intercept for patient was used to study the longitudinal association between tumour size and estimated glomerular filtration rate (eGFR).
RESULTS:
Longitudinal data from 98 patients with 101 lesions were analysed. Most patients were men (68.3%) and the median (interquartile range [IQR]) age was 69 (13) years. The median (IQR) follow-up was 29 (26) months. Most lesions were small renal masses, and 24% measured over 4 cm. Over half (64.4%) grew at a median (IQR) rate of 2 (4) mm per year. No association was observed between tumour size and eGFR over time (P = 0.871). Nine lesions (8.9%) were subsequently treated. Two deaths were reported, neither were related to the diagnosis of renal oncocytoma.
CONCLUSION:
Natural history data from the largest active surveillance cohort of renal oncocytomas to date show that renal function does not seem to be negatively impacted by growing oncocytomas, and confirms clinical outcomes are excellent after a median follow-up of over 2 years. Active surveillance should be considered the 'gold standard' management of renal oncocytomas up to 7cm
Kaluza-Klein Type Robertson Walker Cosmological Model With Dynamical Cosmological Term
In this paper we have analyzed the Kaluza-Klein type Robertson Walker (RW)
cosmological models by considering three different forms of variable :
, and
. It is found that, the connecting free parameters of the
models with cosmic matter and vacuum energy density parameters are equivalent,
in the context of higher dimensional space time. The expression for the look
back time, luminosity distance and angular diameter distance are also derived.
This work has thus generalized to higher dimensions the well-known results in
four dimensional space time. It is found that there may be significant
difference in principle at least, from the analogous situation in four
dimensional space time.Comment: 16 pages, no figur
