ABSTRACT

Powassan virus (POWV) is a tick-borne Flavivirus primarily transmitted through ticks in North America which is a significant public health threat in the northeastern United States. POWV infection spans from Ontario to the Mid-Atlantic, Northeast, and Midwest regions in the USA. Climate change, ecological factors, and human-related changes, including shifts in migration and agriculture, contribute to the dissemination of POWV. Symptoms include sore throat, fatigue, headache, and severe neuroinvasive conditions. Specialized attention is required for diagnosing and managing. MRI scans detect central nervous system abnormalities, while neuromonitoring identifies metabolic distress. Severe cases may necessitate ICU hospitalisation with continuous monitoring. Prevention measures, such as awareness, controlling mammals, and protecting pets, reduce POWV infection risk. The recent outbreak of POWV in Maine, USA, highlights the importance of worldwide collaboration for prevention. With the global prevalence of POWV increasing due to climate and socioeconomic changes, implementing preventative measures and promoting awareness are crucial in reducing infection risk.

ABSTRACT

Background: The World Health Organization (WHO) has been alerted to a concerning upsurge of severe myocarditis, an inflammatory heart condition, in neonates within Wales and South West England. The myocarditis cases are being intricately associated with enterovirus infection, belonging to the Picornaviridae family. The concerned pathogen poses a significant global disease burden, with an estimated 10 to 15 million symptomatic cases occurring annually in the United States alone. Neonates are particularly vulnerable with children under the age of one accounting for approximately 40% of enterovirus infections. Material and Methods: A comprehensive literature search was conducted using various databases including ClinicalTrials, Google Scholar, PubMed, ScienceDirect, MEDLINE, and Ovid Resources. The search strategy included utilizing keywords such as "myocarditis," "Randomized controlled trials (RCTs). Only articles written in English were considered, and selection criteria included relevance to the research objectives, reasonable sample sizes, and robust methodology. In addition to the identified articles, meta-analyses, animal models and studies, and references from the selected articles were also examined to ensure a comprehensive review of the literature. Results: Ten hospitalized neonates, reported in the United Kingdom (UK), with positive PCR tests were reported to have myocarditis, predominantly caused by coxsackieviruses. The current situation in the region has brought global attention. With this study, we hope to draw attention to the critical aspects of the illness and, more crucially, the present strategies required to control the disease outbreak in England. Discussion: Current European Society of Cardiology (ESC) recommendations for the treatment of acute heart failure apply. Emerging research supports the use of immunosuppressive medication in some circumstances. Patients are advised to avoid aerobic activities for several months after healing. Neonatal enterovirus infections can vary in how they respond to IVIG therapy. The majority of enterovirus infections are self-limited, require no special therapy, and only little supportive care is required. Conclusion: The recent elevation in numbers for reported severe myocarditis in neonates within Wales and South West England, linked to enterovirus infection, poses a significant public health concern. Myocarditis caused by enteroviruses, particularly Group B coxsackieviruses, is associated with significant mortality rates. Diagnosis is supported by non-invasive techniques and cardiac enzyme blood tests. Treatment modalities primarily involve a palliative approach.

ABSTRACT

An established commercial grade SrO doped ZTA composition has been considered to design, fabrication through uniaxial pressing followed by sintering and polishing, validation of dimension, 3D surface profile, 3D microstructure, and compressive load bearing capacity of femoral head - acetabular socket liner prototypes for the hip prosthesis. While design and dimensions are concerned, both the steel (HRC60) molds were designed and machined to achieve precious dimensions of femoral head (FH; OD - 30 ± 0.01 mm) and acetabular socket liner (ASL; ID - 30.15 ± 0.01 mm). A close variation in the range of ±0.01 mm was confirmed the precision geometry of polished FH and ASL with consideration of 22 points coordinate measuring method (CMM). 3D surface profile ensures the surface characteristics of Ra = 0.2 ± 0.01 µm and Rq = 0.5 ± 0.01 µm for outer surface of FH and an inner surface of ASL, respectively. Structure integrity and fabrication defects including cracks and pores free bulk structures were confirmed by Micro CT. The compressive load resistance known as burst strength for independent FH and FH-ASL assembly were measured 16.2 KN and 17.6 KN, respectively. The developed ceramic prototypes have an economic advantage and can be adopted as artificial hip prosthesis after extensive in-vitro and in-vivo analysis.

ABSTRACT

BACKGROUND: Peroxidase activity was increased during germination of green gram and such an increase may have benefits in many physiological processes. The present study aimed to investigate the optimum conditions for the extraction, purification and characterization of peroxidase from the germinated green gram roots and also its application for the removal of phenols in water. RESULTS: Peroxidase activity was increased by 300-fold in 5-day germinated green gram. Because the root was rich in peroxidase activity, peroxidase from roots was isolated and purified to homogeneity. The purified peroxidase showed a single band on sodium dodecyl sulphate-polyacrylamide gel electrophoresis with a molecular weight of 50 kDa, an optimum pH of 5.5 and a pH stability ranging from 5 to 9. The enzyme had 50% residual activity at 70 °C. It catalyzed the oxidation of a variety of substrates. The Km value of the enzyme was 1.28 mmol L-1 for o-dianisidine and 0.045 mmol L-1 for H2 O2 . The enzyme lost 100% activity in the presence of dithiothreitol and cysteine. The addition of copper ion increased the enzyme activity by three-fold. Both soluble and immobilized peroxidases removed more phenol than p-chlorphenol, whereas horseradish peroxidase removed more p-chlorphenol. Thus, the green gram root peroxidase showed good pH and temperature stability, as well as the ability to remove phenolic compounds from effluent. CONCLUSION: Peroxidase with good thermal and pH stability was purified from germinated green gram roots and has the ability to oxidize phenolic compounds from waste water. © 2016 Society of Chemical Industry.

ABSTRACT

BACKGROUND: In the present study, the composition of mango peel powder (MPP) collected from the mango pulp industry was determined and the effect of MPP on ameliorating diabetes and its associated complications was studied. RESULTS: Mango peel was rich in polyphenols, carotenoids and dietary fibre. Peel extract contained various bioactive compounds and was found to be rich in soluble dietary fibre. Peel extract exhibited antioxidant properties and protected against DNA damage. Therefore, the effect of peel on ameliorating diabetes was investigated in a rat model of diabetes. A significant increase in urine sugar, urine volume, fasting blood glucose, total cholesterol, triglycerides and low density lipoprotein, and decrease in high density lipoprotein were observed in the rats; however, these parameters were ameliorated in diabetic rats fed with diet supplemented with mango peel at 5% and 10% levels in basal diet. Treatment of diabetic rats with MPP increased antioxidant enzyme activities and decreased lipid peroxidation in plasma, kidney and liver compared to untreated diabetic rats. Glomerular filtration rate and microalbuminuria levels were ameliorated in MPP treated diabetic group. CONCLUSIONS: Mango peel, a by-product, can be used as an ingredient in functional and therapeutic foods.
