The knowledge about termites in restinga (sand dunes and adjacent areas) is incipient in Santa Catarina (SC) State coast, southern Brazil. Aiming to verifiy the diversity of the termitofauna, the presence of possible exotic species as well as aspects of the biology of the existing species, a survey was done in a natural and in an anthropized portion of restinga, from May to December 2009, during 90 hours. Termites were searched visually on different substrates at both places, sampled and conserved for identification. Nests were also searched, opened and studied.

Current researchers are more emphasised towards microbes to meet the antibiotic requirement of mankind. And in this study we made an attempt for the search of antibiotics through isolation of actinomycetes and analysis of their antibiocity through 16s rRNA gene sequencing and identification of restriction site. An Actinomycete species (SN-4) was isolated from botanical garden soil samples of the Karnatak University, Dharwad, India. Morphological, physiological, biochemical and 16S ribosomal RNA studies suggested that the isolate belongs to Streptomyces sp.

A simple, specific, precise and stability-indicating RP-HPLC method was developed and validated for analysis of Curcumin in bulk drug, cream and churna formulations. Chromatographic separation were achieved using Agilent-TC C18 column (250 X 4.6 mm; 5µ) column at ambient temperature. Mixture of methanol, acetonitrile, and 5% acetic acid (35: 50: 15, v/v) was used as mobile phase at constant flow rate of 1.0 ml/min and 420 nm was selected as wave length for detection of method. The Curcumin peak was obtained at RT 4.92 min.

Voltage gated potassium channels is a group of tetrameric signalling proteins with several functions which includes modulation of neuronal excitability and neurotransmitter release. Potassium channel antibody disorder was first described in acquired neuromyotonia condition which is a syndrome of spontaneous and continuous muscle fibre contraction resulting from hyperexcitability of motor nerves. A syndrome from antibodies to voltage gated potassium channel includes Neuromyotonia, Morvan’s syndrome, limbic encephalopathy.

The experiment was conducted on 12 buffaloes between 6 +1 years of age, weighing between 500 + 50 kg kept at dairy farm, Tandojam. Four Kundhi Buffaloes were randomly allocated to each group A, B and C. Buffaloes in group A was fed on conventional ration, buffaloes in group B were fed on scientifically balanced ration prepared by researcher at department of Animal Nutrition, Sindh Agriculture University Tandojam and buffaloes in group C were given commercial dairy ration purchased from Hyderabad market.

This study investigated the capability of a biosurfactant produced by a novel strain of Bacillus subtilis to enhance the biodegradation rates and bioavailability of organic contaminants isolated from soil sample. 10 isolates of Bacillus subtilis were isolated from three different oil contaminated soil samples. All isolates showed α – haemolysis in haemolytic test. In oil displacement test, isolates BS1, BS2, BS3, BS4, BS5, BS7 and BS8 showed zone of diameter 25mm, 13mm, 18mm, 16mm, 9mm, 11mm and 18mm respectively.

This is an explanation of how life might have originated. It is written for non-specialists. The cooling by seawater of rocks under the floor of the ocean, played an important role in the origin of life. Such a process might seem remote from our everyday knowledge of life but it has now been known for more than twenty years that genetically primitive micro-organisms are to be found living at warm springs on the ocean floor.

Experiments were conducted to investigate the correlation of soil properties towards metal loss of API 5L X42 carbon steel coupons, with emphasis on soil pH and resistivity. A total of four pieces of X42 coupons was placed in four different soil samples gotten from four different villages within the Nagapattinam Delta region for 2400 hours, to study the influence of soil properties towards metal loss via weight loss method. The soil coupons were buried in the soil samples placed in a plastic container, allowed to corrode naturally and then retrieved every 240 hours.

Background: Uterine fibroids, or leiomyoma, are tumors or growths made of smooth muscle cells and other tissue in the uterus wall. They are the most common non-cancerous tumors in women of childbearing age. It can cause painful symptoms and abnormal bleeding from the uterus. Fibroids are located in certain parts of the uterus, such as the uterine cavity, can also make it difficult for a woman to get pregnant or maintain a pregnancy.Antibiotics are the more widely used drugs to prevent surgical site infections in gynaecology surgeries even though there was evidence of complication.

The aim of this study is to examine the relationship between the physical and chosen basic motoric characteristics of students aged from 6 to 12 doing regular exercises. The population of the study consists of Tuncay Artun Primary School, Kıraç Primary School, Ümraniye Birlik Primary School, Süleyman Çelebi Primary School and Ragıp Kutmangil Primary School which are all active in İstanbul, and the sample of the study consists of 379 students chosen from these schools.
