Heterogeneous Environment

Phenotypic plasticity among natural plant populations is a species-specific ecological phenomenon of paramount importance that depends on their life forms, development stages, as well as environmental factors. While this phenomenon is broadly understood, it has hardly been observed in nature. This study aimed at understanding phenotypic plasticity and ecological adaptability in three shrubs (Salix etosia, Rubus setchuenensis, and Hydrangea aspera) affected by potential environmental variables after deforesting in sparse Larix spp. forest and tall shrub mixed secondary forests. Soil organic carbon content, total nitrogen content, and available nitrogen content were greater outside the forests, contrary to other measured factors whose availability was higher in the forest interiors. In case of leaf traits and stoichiometric indicators, there were significant interactions of leaf area (LA), leaf dry matter (DW), specific leaf area (SLA), and leaf phosphorus content (LPC) between shrub species and heterogeneous environments (P < 0.05) but not for leaf C/N, N/P, and C/P. Principal components analysis (PCA) indicated that soil temperature, pH value, soil carbon content, soil nitrogen content, and MBC and MBN mainly constituted the first component. Summarized results indicated that TB and leaf C/P of S. etosia were significantly correlated with three principal components, but only marginal significant correlations existed between R/S and relevant components. SLA and R/S of R. setchuenensis had marginal significant relationships with independent variables. Both SLA and TB of H. aspera were significantly correlated with three principal components. Based on the pooled values of leaf functional traits and leaf stoichiometric indicators, R. setchuenensis (vining type) had better leaf traits plasticity to adapt to a heterogeneous environment. In descending order, the ranks of biomass allocation plasticity index of three shrubs were H. aspera (bunch type), R. setchuenensis (vining type), and S. etosia (erect type). The highest integrated plasticity values of leaf traits and biomass allocation was observed in H. aspera (bunch type), followed by R. setchuenensis, and by S. etosia with less adaptive plasticity in heterogeneous environments.

Many coastal foundation plant species thrive across a range of environmental conditions, often displaying dramatic phenotypic variation in response to environmental variation. We characterized the response of propagules from six populations of the foundation species Rhizophora mangle L. to full factorial combinations of two levels of salinity (15 ppt and 45 ppt) reflecting the range of salinity measured in the field populations, and two levels of nitrogen (N; no addition and amended at approximately 3 mg N per pot each week) equivalent to comparing ambient N to a rate of addition of 75 kg per hectare per year. The response to increasing salinity included significant changes, i.e., phenotypic plasticity, in succulence and root to shoot biomass allocation. Propagules also showed plasticity in maximum photosynthetic rate and root to shoot allocation in response to N amendment, but the responses depended on the level of salinity and varied by population of origin. In addition, propagules from different populations and maternal families within populations differed in survival and all traits measured except photosynthesis. Variation in phenotypes, phenotypic plasticity and propagule survival within and among R. mangle populations may contribute to adaptation to a complex mosaic of environmental conditions and response to climate change.

A white boy six months of age was hospitalized with respiratory distress and congestive heart failure. Control of the heart failure was achieved but marked cardiomegaly, moderate hepatomegaly, and minimal muscular weakness persisted.At birth a chest x-ray had been taken because of rapid breathing and jaundice and showed the heart to be of normal size. Clinical studies included: EKG which showed biventricular hypertrophy, needle liver biopsy which showed toxic hepatitis, and cardiac catheterization which showed no obstruction to left ventricular outflow. Liver and muscle biopsies revealed no biochemical or histological evidence of type II glycogexiosis (Pompe's disease). At thoracotomy, 14 milligrams of left ventricular muscle were removed. Total phosphorylase activity in the biopsy specimen was normal by biochemical analysis as was the degree of phosphorylase activation. By light microscopy, vacuoles and fine granules were seen in practically all myocardial fibers. The fibers were not hypertrophic. The endocardium was not thickened excluding endocardial fibroelastosis. Based on these findings, the diagnosis of idiopathic non-obstructive cardiomyopathy was made.

3H-galactose (gal) and 3H-glucose (glu) were compared to determine which compound was preferable for pulse labeling newly formed hepatic glycogen. Control fed rats were used to achieve substantial and consistent levels of hepatic glycogen and to stimulate glycogen synthesis.Rats fed once daily for 4 hr achieved hepatic glycogen levels > 3% wet weight liver prior to injection by tail vein of a tracer dose of 3H-gal or 3H-glu. The rats were sacrificed 15-120 min later and liver was prepared by routine techniques for light (LM) and electron microscopic (EM) radioautography (RAG) and biochemical analysis.

Background & Method: The study was conducted in the Department of Medicine Shyam Shah Medical College and Associated Sanjay Gandhi Memorial Hospital, Rewa (M.P). History was followed by a careful clinical examination i.e. cardiovascular, respiratory and gastrointestinal and nervous system. Investigations had done included routine haematological examination, Biochemical analysis, urine examination, ECG, 2 D. Echo & Histopathological examination was done. Result: ST-T changes were most common finding in Aluminium phosphide poisoning in relation to mortality. However hyperkalemia was the most ominous finding associated with 100% mortality, ECG finding in EDB was normal ECG. The most ominous finding was arrhythmia which was associated with 100% mortality. Survivors of ethylene dibromide poisoning echocardiography was normal in 11 (84.61%) followed by pericardial effusion in 2 (15.38%) patients. Conclusion: Noteworthy finding was absence of correlation between cardiovascular involvement, histopathological changes and ECG findings. It was seen that even if ECG showed normal pattern there were significant histopathological changes in heart. Keywords: electro-cardiographic, Aluminium phosphide, ethylene dibromide & poisoning.
