Antibody detection and accurate diagnosis of tropical diseases is essential to help prevent the spread of disease. However, most detection methods lack cost-effectiveness and field portability, which are essential features for achieving diagnosis in a timely manner. To address this, 3D-printed oblate spheroid sample chambers were fabricated to measure green light scattering of gold nanoparticles using an optical caustic focus to detect antibodies. Scattering signals of 20-200 nm gold nanoparticles using a green laser were compared to green light emitting diode (LED) light source signals and to Mie theory...

Egyptian monazite is a promising resource and investment attractive for production of valuable metals of industrial or nuclear interest such as rare earth elements (REEs), thorium (Th) and uranium (U). The study was focused to establish a baseline framework in viewpoint of radiation protection for the workers in production of REEs from high-grade monazite treated by sodium hydroxide (NaOH) solutions. Radiological hazard indices (cancer, gonadal and other risks) were evaluated, due to emissions (α-, β- and γ-radiations) of radium-isotopes ((228)Ra, (226)Ra, (223)Ra) and lead ((210)Pb)...

The purpose of this article is to evaluate the effect of adsorbents and alkali pre-treatment on microorganism activities of activated sludge (AS) for the treatment of landfill leachate (LFL). The COD and BOD5/COD ratio of LFL used in this research were 10500 and 0.68, respectively which they show the efficient biodegradation of LFL by aerobic bacteria. In order to survey the role of porous absorbent, perlite was employed as an alternative with low porosity and was compared to powdered activated carbon (PAC) which has been most widely used in the treatment process...

Lignocellulosic biomass, a matrix of the biopolymers including cellulose, hemicellulose and lignin, has gathered increasing attention in recent years in the production of chemicals, fuels and materials based on biorefinery processes due to its renewability and availability. Fractionating lignocellulose is considered as the foundational step to establish an economical and sustainable lignocellulosic biorefinery. This Minireview summarized a newly developed oxygen delignification for lignocellulose fractionation called cooking with active oxygen and solid alkali (CAOSA), which could fractionate lignocellulose into its constituents while remaining in processable form...

Andrew Ja Holland, Soundappan Sv Soundappan
Trauma and injury continue to be common in children and remain an important cause of mortality and morbidity. Legislation mandating the use of helmets for all cyclists appears to have been effective in reducing the incidence and severity of head and facial injuries, with no clear evidence of a reduction in cycling usage or activity. Straddle injuries, whilst uncommon and generally minor, require careful clinical assessment as they may be associated with urethral trauma. Quad bikes remain highly dangerous with continuing reports of deaths in child riders due to their inherent lack of stability: a ban on their use by children would seem the most effective solution...

Facial warts are a common cause of cosmetic concern and also affect the self-esteem of the affected patients. These are benign skin papillomas caused by human papillomavirus infections. Warts affecting the face are mainly due to HPV-3 and HPV-10. Destructive and caustic agents used for the treatment can produce scarring at these site, hence should be used with care. Earlier, glycolic acid alone as well as in combination with salicylic acid in gel base formulation have been used to treat facial recalcitrant wart with good results...

Pristine rice husk (RH), a kind of agricultural waste based biosorbent, was chemically modified by introducing sulfur-bearing groups with the CS2 treatment under caustic medium. Using response surface methodology (RSM), the interactive effects of three preparation variables on the cadmium uptake and material yield of xanthate-modified rick husk (RH-X) were investigated, and two quadratic regression models were developed to correlate the preparation parameters to the two responses. Through process optimization, the optimal RH-X was finally obtained under the optimum synthesis conditions (i...

BACKGROUND: Pharyngoesophageal strictures (PES) after corrosive injury impose a problematic condition for both physicians and patients in terms of their management and patients' quality of life. Colopharyngoplasty is a complex procedure, which is used to restore swallowing in these severely disabled patients. We describe our experience in treating nine patients with severe PES after corrosive injuries in a referral center. MATERIALS AND METHODS: A retrospective analysis of our database from 2009 to 2014 showed nine patients (seven men; age range: 18 to 47 years) with severe PES who underwent colopharyngoplasty ∼6 months (range: 4-10) after caustic material ingestion...

INTRODUCTION: One of the leading causes of damage to the gastrointestinal tract in children is caustic ingestion which is sometimes life-threatening. The most reliable way to study the severity and extent of damage is endoscopy, which can be harmless in terms of time and technique. The aim of this study was to investigate, evaluate and compare clinical findings and endoscopic results of caustic ingestion. METHODS: This retrospective cross-sectional study was conducted on the records of children diagnosed with caustic ingestion, and hospitalized in Qa'em Hospital of Mashhad from March 2011 to December 2013...

Cement burn is a common cause of chemical burns in France. They usually need surgical treatment. This retrospective study was performed among 49 patients, aged 21-71 years, admitted to the St Joseph-St Luc Hospital in Lyon, France. Patients were mainly male, fairly young (mean 44 years) and had a professional activity, although burns usually occurred at home. Burns were deep, on the lower limbs, and were not extensive (3% TBS). All but one patient needed grafting, performed on d13. LOS was eight days. Seven patients had to be admitted to a rehabilitation centre afterwards...

BACKGROUND: Esophageal stenosis (ES) is characterized by dysphagia, failure to thrive, and long-term disability. It requires repeated management because it is refractory. Traditionally, these procedures are performed under general anesthesia with airway intubation. PURPOSE: This study investigated the safety and efficacy of the management of interventional flexible endoscopy (IFE) performed with a novel noninvasive ventilation (NIV) support. METHODS: Use of a short-length flexible endoscope with NIV of pharyngeal oxygen, nose closure, and abdominal compression during IFE was investigated...

For many decorative applications like industrial and architectural paints, prevention of metal substrates from corrosion is a primary function of organic coatings. Triggered release of inhibitor species is generally accepted as a remedy for starting corrosion in case of coatings damage. A polyurethane based coating, doped with bola-amphiphiles of varying molecular weight but with a common head group motif that stems from ring-opened alkenyl succinic anhydride, enables passivation of the defect and mitigates cathodic delamination, if applied on cold rolled steel...

Periodic caustic shock-loading is a commonly used method for sulfide control in sewers. Caustic shock-loading relies on the elevation of the sewage pH to ≥10.5 for several hours, thereby removing sewer pipe biofilms as well as deactivating SRB activity in the remaining biofilm. Although a widely used method, SRB activity is often not completely inhibited, and as such sulfide is still being generated. Here, we propose and experimentally demonstrate an innovative approach which combines caustic with oxygen, another commonly used method, as a dosing strategy for overcoming the drawbacks of caustic shock-loading...

In the present study, the production of various transient forms of sulfur during biological oxidation of sulfidic spent caustics under haloalkaline conditions in a stirred tank bioreactor is investigated. Also, the effects of abiotic aeration (chemical oxidation), dissolved oxygen (DO) concentration and sodium concentration on forms of sulfur during biological treatment are demonstrated. Thioalkalivibrio versutus strain was used for sulfide oxidation in spent caustic (SC). The aeration had an important effect on sulfide oxidation and its final products...

Caustic paste disbudding is becoming more commonplace in North America. A large body of work has examined pain control for cautery disbudding and surgical dehorning, but fewer studies have evaluated pain control for caustic paste disbudding, and results conflict regarding benefits of local anesthesia. In humans, the pain associated with a caustic, chemical burn can differ in nature, duration, and intensity compared with a thermal burn. The objective of this clinical trial was to evaluate the effects of either a lidocaine cornual nerve block or a topical anesthetic incorporated into caustic paste on the acute pain of caustic paste disbudding...
