TL;DR: In this article, the authors evaluated the groundwater quality and conduct a non-carcinogenic risk assessment of nitrate contamination in an industrialized and high-density region of South India.
Abstract: The primary goal of this study is to evaluate the groundwater quality and conduct a non-carcinogenic risk assessment of nitrate contamination in an industrialized and high-density region of South India. A total of 40 sampling sites were identified in and around the industrial area, and samples were collected during the pre-monsoon and post-monsoon seasons. Piper and Gibbs’ diagram shows that rock-water interaction, lithological characteristics and ion-exchange processes are the primary factors determining groundwater quality. The novel entropy water quality index (EWQI) indicated that 32 and 37.5% of the water in the study area were unsuitable for drinking purposes during both the pre-monsoon and post-monsoon seasons, respectively. Due to landfill leachate and modern agricultural activity, the nitrate concentration in groundwater post-monsoon had increased by 17.11%. The nitrate pollution index (NPI) value of groundwater exceeded the contaminated level by 22.77%. The non-carcinogenic human health risk assessment revealed that 35 and 40% of adult males, 37.5 and 52.5% of adult females and 42.5 and 55% of children during the pre-monsoon and post-monsoon periods were exposed to an increased concentration of nitrate in groundwater. The non-carcinogenic risk level to the exposed population in the study region descends in the following order: children > > females > males. The study suggests that low body weight in children is a direct result of consumption of low-quality water and that adult men and women suffer less severe consequences.

TL;DR: In this article, the influence of direct and alternating current on electrocoagulation process in terms of % color and % COD removal along with electrical energy consumption from distillery industrial effluent was analyzed.
Abstract: The main objective of this study is to analyze the influence of direct and alternating – current on electrocoagulation process in terms of % color and % COD removal along with electrical energy consumption from distillery industrial effluent. The percentage of color and COD removal and electrical energy consumption were about 90.57%, 86.54% and 3.50 kWhr/m3 with Direct – Current Electrocoagulation (DCE). For Alternating – Current Electrocoagulation (ACE), it was 100%, 95% and 3.20 kWhr/m3, respectively at the optimal experimental condition of COD – 3000 mg/L, initial wastewater pH – 7, current density – 0.4 A/dm2, inter–electrode spacing – 1 cm, combination of electrode – Fe/Fe, pulse duty cycle – 0.45, frequency – 50 Hz and treatment time – 3.5 h. The ACE was more successful in eliminating % color and % COD with less electrical energy consumption than DCE process. In DCE, the formation of an impermeable oxide layer on the cathode and the occurrence of corrosion on the anode due to oxidation have decreased the efficiency of this process compared to the ACE process. As a result, experimental findings have shown that with less electrical energy usage and process efficiency, the ACE could be a more promising solution to removing pollutants from wastewater and industrial effluent than the DCE method.

TL;DR: Despite the existence of trypanosome and high tsetse fly infestation in the areas, large proportion of the Mursi cattle shows medium BCS, low tryPanosome prevalence, and higher PCV value.
Abstract: The study was conducted to characterize the morphological features of Mursi cattle breed and to identify the species of trypanosome infecting the cattle and its prevalence in these traditionally managed cattle in the Bodi and Mursi pastoral communities. Cattle body description and measurements were made on 201 matured animals. Blood samples were collected from 409 animals into heparin-treated capillary tubes and were centrifuged to 12,000 rpm for 5 min to identify trypanosome species from the wet smeared buffy coat and to estimate the degree of anemia (PCV). Tsetse flies were collected using phenol-treated biconical trap and the caught flies identified to species level. The breed possesses variable coat color pattern, coat color type, and have small to medium hump size on the thoracic vertebrae. Body measurement of Mursi cattle in the two locations did not show significant differences except chest girth, rump width, and horn length. Trypanosome prevalence in the Mursi cattle breed was 6.1 %. The highest trypanosome infection was caused by Trypanosoma congolense (56 %) followed by Trypanosoma vivax (40 %) and Trypanosoma brucei (4 %). Trypanosome prevalence significantly varies between dry (2.0 %) and late rainy (10.1 %) seasons (P < 0.001) and between lean (11.9 %) and medium (2.4 %) body condition score (P < 0.01). The PCV value was 22.1 ± 0.5 %, which is significantly varied with season (P < 0.01) and parasitism (P < 0.001). Parasitaemic cattle show the lowest PCV value (20.4 ± 1%) than aparasitaemic (23.7 ± 0.3 %) cattle and cattle with lean BCS showed the lowest (P < 0.0001) PCV value (20.4 ± 0.6 %). Tsetse fly species identified in the study area were Glossina pallidipes, Glossina morsitans submorsitans, and Glossina fuscipes. The number of flies captured in late rainy season was higher than in dry season (P < 0.01). Despite the existence of trypanosome and high tsetse fly infestation in the areas, large proportion of the Mursi cattle shows medium BCS, low trypanosome prevalence, and higher PCV value.

TL;DR: The role of various biosensors in disease detection and diagnosis is discussed, and use of different nanostructured materials in biosensor demonstrate appropriate sensitivity, specificity and efficient diagnosis.
Abstract: In order to determine the health status of people and provide the most appropriate treatment, rapid and accurate diagnosis is required. Recently all the clinical analysis is piloted in specialized laboratories which require specific and automated instruments. The pre-diagnosis of any disease is important in effective treatment and it becomes a lifesaving option. The conventional disease diagnostic methods require highly skilled labor, use expensive chemicals and are time consuming. They also suffer from problems like less sensitivity and specificity. Biosensors can help address these problems and provide specific, fast diagnosis with low cost, ease of use and portability. Biosensors are instruments which have a capability to detect a biological compound like nucleic acids and proteins. They may be optical, piezoelectric, and electrochemical. This review discusses the role of various biosensors in disease detection and diagnosis. Use of different nanostructured materials in biosensors is also being reviewed. These devices demonstrate appropriate sensitivity, specificity and efficient diagnosis.
