Accelerated mineralization of textile wastewater under 222 nm irradiation from Kr/Cl excilamp: an environmentally friendly and energy efficient approach.

The textile dyeing and manufacturing industry is the major producer of significant amounts of wastewater that contain persistent substances such as azo dyes that require adequate remediation measures. Far ultraviolet at 222 nm light may provide an advantage for contaminants degradation as compared to conventional UV sources (254 nm). In this paper, the degradation of reactive black 5 (RB5) in artificial wastewater has been performed using a 222 nm Kr/Cl excimer source under direct photolysis and an advanced oxidation process using TiO/HO.

Environmentally Friendly UV-C Excimer Light Source with Advanced Oxidation Process for Rapid Mineralization of Azo Dye in Wastewater.

Wastewater discharged from the textile industry contains approximately 15% unfixed dyes, predominantly 60-70% azo dyes. These unfixed dyes are a major environmental concern due to their persistence and potential toxicity. In this paper, an environmentally friendly mercury-free XeI* excilamp emitting 253 nm UV light is reported, and the same has been utilized for the degradation of azo dyes using the advanced oxidation process (AOP) with TiO/HO.

Analysis of a UV photocatalytic oxidation-based disinfection system for hydroxyl radicals, negative air ions generation and their impact on inactivation of pathogenic micro-organisms.

This work presents a large-scale surface disinfection system, which has a unique lantern arrangement of ultraviolet-C (UV-C) light (254 nm) in conjunction with nanotechnology in a protective biosafety environment. Shadow regions are best dealt in this system by the generation of hydroxyl radicals (•OH) and negative air ions at sites where UV light cannot penetrate. More than 35 000 negative air ions/cm3 along with •OH were produced continuously in the disinfection chamber through the advanced photocatalytic oxidation process [UV-C + titanium dioxide (TiO2)].

Evaluation of Multiparametric Magnetic Resonance Imaging and Correlation with Radical Prostatectomy Histopathology Specimen in Prostate Cancer.

Magnetic resonance imaging (MRI) has shown a great potential in the evaluation and management of prostate cancer. In this study, we would like to evaluate the benefit of multiparametric MRI in the detection and localization of prostate cancer by comparing it with the gold standard of histopathology from radical prostatectomy. In this single-centre prospective study, 90 consecutive patients underwent radical prostatectomy from November 2016 to May 2018.

Efficient deactivation of aerosolized pathogens using a dielectric barrier discharge based cold-plasma detergent in environment device for good indoor air quality.

Air pollution is one of the top 5 risks causing chronic diseases according to WHO and airborne transmitted pathogens infection is a huge challenge in the current era. Long living pathogens and small size aerosols are not effectively dealt with by the available indoor air purifiers. In this work, a dielectric barrier discharge (DBD) based portable cold-plasma detergent in environment device is reported and its disinfection efficiency has been analyzed in the indoor environment of sizes up to 3 × 2.

Photocatalytic oxidation conveyor "PCOC" system for large scale surface disinfection.

In this paper, we present a surface decontamination system that substitutes traditional chemicals and scrubbing agents, which will be useful for the general public during a pandemic. The technique is based on a hybrid process in which UV-C light and its photons interact with metal oxide nano-catalysts to generate hydroxyl radicals, which can enhance the deactivation process, and the system can work even in the shadow regions via a dry process. The optimum number of UV light sources in combination with TiO nanoparticles catalysts on aluminum plates have been used synergistically in the system.

Congenital Thymic Cyst: Antenatal Diagnosis and Postnatal Management.

Thymic cyst is regarded as a rare anomaly, accounting for about 3% of all anterior mediastinal masses. It can be either congenital or acquired. Congenital thymic cysts are usually asymptomatic, with about 50% found incidentally in childhood or adolescence.

Core Biopsy Diagnosis of ALK Positive Inflammatory Myofibroblastic Tumor of Lung: An Interesting Case.

Inflammatory myofibroblastic tumor (IMT) of lung is a rare tumor, accounting for ~0.7% of all lung tumors with varied clinical and radiological presentations. The origin of this tumor is unknown but some studies suggest that it might be a true neoplasm as some mutations on chromosome 2p23 of anaplastic lymphoma kinase (ALK) have been found to be related to this tumor.

Schmorl's Node: Confusion Still Persists in 68Ga-Prostate-Specific Membrane Antigen Ligand PET/CT.

Ga-prostate-specific membrane antigen (PSMA) ligand PET/CT is commonly believed to be prostate specific as the name itself suggests. However, PSMA-expressing nonprostatic cancers as well as benign lesions are continuously being added to the list. We reported PSMA-expressing Schmorl's node in L1 vertebra of a 74-year-old man with prostate cancer.

Multiparametric magnetic resonance imaging-transrectal ultrasound fusion prostate biopsy: A prospective, single centre study.

Introduction: Transrectal rectal ultrasound (TRUS)-guided systematic biopsy is the gold standard for diagnosis of prostate cancer. However, systematic biopsy has high false-negative rate and often misses anteriorly located tumors. Magnetic resonance imaging (MRI)-TRUS fusion biopsy can potentially improve cancer detection by better visualization and targeting of cancer focus.

Quantification of coronary artery motion and internal risk volume from ECG gated radiotherapy planning scans.

Background: Radiotherapy for carcinoma of breast and thoracic structures involves inadvertent radiation to heart and coronary arteries (CA). Coronary artery stenosis in high radiation dose segments has been documented. Cardiac and respiratory motion induced displacement of CA and internal risk volume (IRV) margin remains inadequately quantified.

Vascular complication after sacrospinous ligament fixation with uterine preservation.

Aim Of The Video: Sacrospinous ligament fixation (SSLF) is a minimally invasive transvaginal procedure for correcting apical prolapse. Amongst perioperative complications, life-threatening hemorrhage has a reported occurrence rate ranging from 0.2 % to 2 %.

Pentalogy of Cantrell associated with exencephaly and spinal dysraphism: antenatal ultrasonographic diagnosis. Case report.

The pentalogy of Cantrell, a rare syndrome, consists of the defects in the anterior diaphragm, diaphragmatic pericardium, lower sternum and supraumbilical abdominal wall, along with congenital cardiac abnormalities. Till date, only few patients with full spectrum of this syndrome have been reported with only 2 cases showing associated exencephaly and spinal dysraphism. We report extremely rare association of complete pentalogy of Cantrell syndrome with exencephaly and spinal dysraphism on antenatal sonogram and autopsy in a 18 weeks fetus of a 19 year-old primi gravida female.

Detection of orbicularis oris muscle defects in first degree relatives of cleft lip children using ultrasound.

Objective: The severity of cleft lip (CL) varies considerably from complete bilateral CL and palate at one end of the spectrum to a minimal CL at the other. In some cases of microform clefting, there may be no visible manifestation of the defect on the lip surface (i.e.

Trans fats-sources, health risks and alternative approach - A review.

Trans fatty acids have the presence of one or more double bonds in the trans configuration instead of the usual cis configuration. They are desired by Vanaspati industry as they impart firmness to margarines and plasticity as well as emulsion stability to shortenings. Research has proved the direct connection of trans fatty acids with cardiovascular diseases, breast cancer, shortening of pregnancy period, risks of preeclampsia, disorders of nervous system and vision in infants, colon cancer, diabetes, obesity and allergy.
