Wenchengia alternifolia Lamiaceae is an enigmatic plant species endemic to Hainan Island, China. For most of the past half-century, it is known mainly from two collections and was once suggested to be extinct until a remnant population was rediscovered in 2010 by the authors. We expanded field surveys and finally located two subpopulations and counted a total of 66 individuals. Thus W. alternifolia represents one of the most endangered species within Lamiaceae and falls within the Critically...
Aquaculture has been accepted the world over as a means for increasing fish production and a developing country like Nigeria with her immense resources offer tremendous possibilities for fish culture (Dada and Gnanadoss, 1983). Aquaculture expansion has been in slow process as private sector fish farmers face major constraints, such as lack of seed and quality feed (FAO, 2003). Fish is an important source of both food and income to many people in developing countries. In Africa, as much as 5%...
The re-designation of Acute Renal Failure by Acute Kidney Injury is not reflected in the current diagnosis and stratification of patients. Despite the change in nomenclature AKI diagnosis is limited to the use of functional surrogates of change in GFR: plasma creatinine and urine output. Plasma creatinine delays AKI diagnosis by 1-3 days 13, 205, 398. Urine output is possibly earlier, but is unreliable. Biomarkers reflecting injury promise earlier diagnosis. However, their performance in...
Abstract Caffeic acid phenethyl ester (CAPE) is one of the major components of honeybee propolis and its structure is similar to flavonoids. The molecular mechanisms of CAPE on various systems including cardiovascular system have not been known well. The aim of the present study was to investigate the short term dose dependent in vivo cardiovascular effects including heart rate and blood pressure changes induced by CAPE in Sprague Dawley rats. The rats were anaesthetized and randomly divided...
A Bacterial spore (endospore) is a bacterium that has formed a thick outer wall to be able to survive in extreme environmental conditions, that it wouldn't normally live in. Some of these conditions include high temperatures, dryness, toxic chemicals ...etc. The vegetative portion of the bacterium is tarnished as soon as the endospore is made, and the inactive endospore is freed. The endospore is capable of living for long periods of time since it is protected. Any bacterial spores that...
Sugar beet industries produces sugar beet pulp as a by product. EU only produces the 108 ton per year (Spagnuolo et at. 1997). Sugar beet pulp should be important renewable resources, its bioconvertion resources appeares to be of great biotechnological importance. Almost 250 kg of exhausted pressed pulp producing when 1 tone sugar beet pulp use, with the water content aproximetely 75-80% (Spagnuolo et al. 1997). The lignocellulosic fractional of dried pulp composed of 3 to 4 % lignin, 24 -32%...
Microbes play an important role in peoples everyday lives. They are responsible for diseases such as the common cold, and are important in the food industry in items like yoghurt and bread (Willey et al. 2008). Another place that microbes live is in soil. Microbes that inhabit the soil are less obvious to people, but not any less important. These microbes play critical roles in nutrient cycling and decomposition (Whitman et al. 1998). Without these processes, plants, and therefore animals and...
Genetic engineering is defined as the technology whereby the genes of an organism are manipulated directly. The structure and the characteristics of a cell are altered directly through the use of transformation and molecular cloning techniques. The term genetic engineering originated from Dragon's Island, a science fiction novel written by Jack Williamson and published in 1951. Scientists have advanced in the field of genetic engineering. After the successful cloning of animals, they are now...
Aldosterone is a mineralcorticoid that is secreted by cells of the adrenal cortex. Aldosterone has multiple effects on multiple organ systems, including maintaining sodium, potassium, and acid-base balance in the kidney (Good 2006) and colon (Harvey 2002). Aldosterone is traditionally known to mediate its effects by genomic mechanisms, which consists of altering RNA transcription and protein synthesis. However, aldosterone can also mediate rapid, non-genomic effects by activation of multiple...
Achieving his own biological child is only possible for an azoospermic man as long as he produces sperm or sperm precursors in the testicles. In Denmark it is not allowed to use sperm precursors for fertilization of oocytes. In order to optimize the testicular sperm extraction procedure (or in particular cases: epididymal sperm aspiration) on those men where the biopsy actually contains useful spermatozoa, the role of a lot of hormones and growth factors including Follicular Stimulating Hormone...
