Qualitative Analysis of Subsurface Water Quality in Challakere Taluk, Karnataka, India
Rural India relies mainly on groundwater for drinking and agriculture. Unsustainable withdrawal of groundwater has led to the spectra of depleting the problem of water scarcity. The available groundwater quality is not only contaminated by hazardous pathogenic germs and anthropogenic substances but also geogenic substances is adversely affect the water supply of many regions. The groundwater of Challakere taluk had many threats such as anthropogenic activities, quality deterioration by agricultural activities and over exploitation and also persistence of continuous drought condition. This paper mainly addresses the physico-chemical concentration of 30 groundwater samples during August 2009 in Challakere taluk, Karnataka (India). The results of all the findings are discussed in details which reflect the present status of the groundwater quality of the study area. Groundwater is extremely important to the future economy and growth of rural India. If the resource is to remain available as high quality water for future generation it is important to protect from possible contamination. Hence it is recommended that suitable water quality management is essential to avoid any further contamination
Gene Expression Profiling of Preovulatory Follicle in the Buffalo Cow: Effects of Increased IGF-I Concentration on Periovulatory Events
The preovulatory follicle in response to gonadotropin surge undergoes dramatic biochemical, and morphological changes orchestrated by expression changes in hundreds of genes. Employing well characterized bovine preovulatory follicle model, granulosa cells (GCs) and follicle wall were collected from the preovulatory follicle before, 1, 10 and 22 h post peak LH surge. Microarray analysis performed on GCs revealed that 450 and 111 genes were differentially expressed at 1 and 22 h post peak LH surge, respectively. For validation, qPCR and immunocytochemistry analyses were carried out for some of the differentially expressed genes. Expression analysis of many of these genes showed distinct expression patterns in GCs and the follicle wall. To study molecular functions and genetic networks, microarray data was analyzed using Ingenuity Pathway Analysis which revealed majority of the differentially expressed genes to cluster within processes like steroidogenesis, cell survival and cell differentiation. In the ovarian follicle, IGF-I is established to be an important regulator of the above mentioned molecular functions. Thus, further experiments were conducted to verify the effects of increased intrafollicular IGF-I levels on the expression of genes associated with the above mentioned processes. For this purpose, buffalo cows were administered with exogenous bGH to transiently increase circulating and intrafollicular concentrations of IGF-I. The results indicated that increased intrafollicular concentrations of IGF-I caused changes in expression of genes associated with steroidogenesis (StAR, SRF) and apoptosis (BCL-2, FKHR, PAWR). These results taken together suggest that onset of gonadotropin surge triggers activation of various biological pathways and that the effects of growth factors and peptides on gonadotropin actions could be examined during preovulatory follicle development
Narendra,Hina Kousar,
Abstract: Medical waste is classified as solids, liquids, and laboratory waste that are potentially infectious or dangerous and are considered biomedical waste. In this study design, consisting of participant observation and interviews, among 16 health centers of Mysore District of Karnataka. This paper presents an overview of the current management practices of health care waste in the hospital of Mysore District area. Generation, composition, segregation, transportation, and disposal of biomedical waste and impact of poor management of medical waste to public health and environment are also studied
INDUCED BREEDING OF LABEO ROHITA AT NATIONAL FISH SEED FARM
The present paper deals with the induced breeding of Labeo rohita using ovaprim and ovatide (a spawning hormone containing salmon gonadotropin RH and domperidone) under moderate temperature (22-23°C) condition at National Fish Seed Farm. Bhadra Project, Karnataka. Optimum dose. fertilization percentage and hatching percentage have been calculated. The advantage of ovatide in induced breeding of Indian major carp. L. rohita is discussed. Success of the experiment at malnad region has brightened prospects of commercial exploitation of the species in Karnataka
