Marine litter in the coastal environment of Mangalore

The continuous flow of large quantities of plastics and waste from land and sea based sources result in a gradual build up of litter in the marine and coastal environment. Plastics and other man-made objects cause serious impacts on environment, economics, safety and health. Worldwide, millions of marine mammals, birds, turtle and fish perish as a result of entanglement or ingestion of discarded debris. Marine litter spoils beaches, floats on the sea surface, drifts in the water column due to the current and is also found on the deep sea bed

Evaluation of Fungicides, Soil Amendment Practices and Bioagents against Fusarium solani-Causal Agent of Wilt Disease in Chilli

Chilli is affected by the wilt disease caused by Fusarium solani, under irrigated conditions. In absence of resistant cultivars, the disease needs to be controlled by management practices. In vitro evaluation of six fungicides by Poisoned Food Technique showed that a combination of carbendazim+mancozeb was effective in inhibiting mycelial growth (93.6%), followed by Carbendazim alone (92.4%). In vivo soil drench using the same fungicides proved effective in controlling the pathogen. Integration of different treatments, including seedling dip, with Carbendazim, addition of vermicompost, drenching with fungicide, and application of Trichoderma viride was found to be effective in managing the disease, in comparison to individual treatments

Prevalence of fatty liver disease in children with obesity- a diagnostic study based on its ultrasound appearance

Background: Non-alcoholic fatty liver disease is an asymptomatic involvement of the liver, can progress to chronic liver disease and must be identified at an early stage for good prognosis. The implementation of the appropriate therapeutic interventions is determinant of the attempts to treat it. For that purpose, early diagnosis and staging of the disease is essential. It seems that diagnostic imaging should be a first-line tool for the staging and monitoring pediatric NAFLD/NASH for appropriate interventions to be implanted in a timely way. This study evaluated the prevalence of fatty liver in relation with body mass index (BMI) by means of ultrasound in children of age group 6-15 years.Methods: In this cross-sectional study, 83 children aged 6 to 15 years, were selected randomly. The participants were examined by a pediatrician. Liver ultrasound was performed for all children and grade of fatty liver was determined.Results: There was a significant correlation between grade of fatty liver with BMI, our study showed a strong association between BMI and prevalence of fatty liver on ultrasound.Conclusions: According to the study hypothesis, based on BMI, the degree of NAFLD in children were predictable. Ultrasound of liver in grading of fatty liver is one of the assessments methods of fatty liver but it is not a diagnostic method; it is useful for prevention to reduce BMI

A Group Theoretical Identification of Integrable Equations in the Li\'enard Type Equation x¨+f(x)x˙+g(x)=0\ddot{x}+f(x)\dot{x}+g(x) = 0 : Part II: Equations having Maximal Lie Point Symmetries

In this second of the set of two papers on Lie symmetry analysis of a class of Li\'enard type equation of the form $\ddot {x} + f(x)\dot {x} + g(x)= 0$, where over dot denotes differentiation with respect to time and $f(x)$ and $g(x)$ are smooth functions of their variables, we isolate the equations which possess maximal Lie point symmetries. It is well known that any second order nonlinear ordinary differential equation which admits eight parameter Lie point symmetries is linearizable to free particle equation through point transformation. As a consequence all the identified equations turn out to be linearizable. We also show that one can get maximal Lie point symmetries for the above Li\'enard equation only when $f_{xx} =0$ (subscript denotes differentiation). In addition, we discuss the linearising transformations and solutions for all the nonlinear equations identified in this paper.Comment: Accepted for publication in Journal of Mathematical Physic

Friend Turns Foe: Transformation of Anti-Inflammatory HDL to Proinflammatory HDL during Acute-Phase Response

High-density lipoprotein (HDL) is a major carrier of cholesterol in the blood. Unlike other lipoproteins, physiological functions of HDL influence the cardiovascular system in favorable ways except when HDL is modified pathologically. The cardioprotective mechanism of HDL is mainly based on reverse cholesterol transport, but there has been an emerging interest in the anti-inflammatory and antioxidant roles of HDL. These latter activities of HDL are compromised in many pathological states associated with inflammation. Further, abnormal HDL can become proinflammatory contributing to oxidative damage. In this paper, we discuss the functional heterogeneity of HDL, how alterations in these particles in inflammatory states result in loss of both antioxidant activity and reverse cholesterol transport in relation to atherosclerosis, and the need for assays to predict its functionality

Effect of Various Plant Extracts on Dry Root Rot of Chillies Caused by Sclerotium rolfsii

Eight different plant extracts were evaluated in vitro against Sclerotium rolfsii causing dry root rot in chillies. Among these, leaf extract of neem (Azadirachta indica) caused maximum inhibition of mycelial growth (80.74%), followed by periwinkle Vinca rosea (78.8%) and bottlebrush (Callistemon, 74.8%) respectively. Sclerotial production was inhibited to an extent of 11% and the inhibition caused was maximum with neem extract, followed by Polyalthia longifolia and V. rosea extracts. Though sclerotial germination was inhibited by 30% to 95% in various treatments, the most effective treatment was that of neem leaf extract (95%), followed by ginger extract (92%)
