Carbon fiber microelectrodes (CFEs) are useful when combined with electrochemical techniques for measuring changes in neurotransmitter concentrations. We addressed conflicting details regarding the use of CFEs. Experimental groups consisted of CFEs at different ages (1 week, 1 month, or 2 months), cleaned in solvents (isopropanol or xylene), and exposed to in vitro use (flow cell calibrations) or in vivo use (in brain tissue). In order to determine if any of these factors affect CFE sensitivity, the present study utilized fixed potential amperometry and a flow injection system to calibrate CFEs for the measurement of dopamine. The sensitivity index (nA/μM per 100 μm of exposed carbon fiber) was not affected by the age of CFEs or pre-cleaning with xylene or isopropanol. CFE sensitivity of the in vitro exposure group also did not differ from untreated CFEs, indicating the calibration process did not alter sensitivity. However, in vivo use in brain tissue did reduce sensitivity. This effect was negated and sensitivity restored by cleaning CFEs in isopropanol or xylene following in vivo brain recordings. Given that variations in CFE sensitivity can skew results, our findings can help standardize CFE use and explain discrepancies between researchers.

Neurotoxicity is an infrequent adverse reaction to iodinated contrast agents. Contrast induced neurotoxicity following coronary angiogram is very rare. Renal disease is a risk factor for contrast induced neurotoxicity. We report a case of contrast induced neurotoxicity following coronary angiogram and intervention using Iohexol(Omnipaque 350) in an end stage renal disease patient on peritoneal dialysis who had prior exposure to iodinated contrast without any adverse reaction. Hemodialysis had to be initiated for rapid removal of the contrast agent with subsequent complete resolution of neurological deficits. This case highlights the need for interventionalists to be aware of an important adverse reaction to iodinated contrast agents, especially in individuals with renal dysfunction, and that neurotoxicity is a possibility even with prior uneventful exposures. The role and timing of hemodialysis in contrast induced neurotoxicity in patients with chronic kidney disease and in those without chronic kidney disease needs further deliberation.

We report here an anomalous origin and course of left colic artery in relation to pancreas during routine dissection of the abdominal region in a 70-year-old male cadaver in the department of anatomy. The anomalous left colic artery took its origin from the superior mesenteric artery and immediately divided into right and left branches. The right branch passed through the transverse mesocolon to supply the left one third of the transverse colon. The left branch traversed to the left along the inferior border of the body of the pancreas and crossed the left kidney before supplying the left colic flexure of colon and descending colon. This aberrant course of the left branch of the left colic artery can be considered as a “vulnerable” course as it is liable to injury during pancreatic and renal surgeries since the artery is not expected to run along the inferior border of the pancreas. The pancreas, a retroperitoneal organ, is related to major arteries such as abdominal aorta, inferior vena cava, coeliac trunk and its main branches, superior mesenteric vessels, splenic and portal veins. Surgery of the pancreas therefore, not only needs a thorough knowledge of the normal course of branches of these vessels but also demands a good knowledge of possible anomalous vessels arising in this region.

真菌毒素(Mycotoxin)是真菌产生的有毒次级代谢产物,大多数真菌毒素经受过饲料加工过程中的高温和高压后性质仍然十分稳定。谷物易受多种真菌毒素污染,是人畜真菌毒素的主要摄入来源,真菌毒素在谷物中的污染十分普遍。目前真菌毒素污染问题在饲料原料、青贮饲料和成品饲料中越来越普遍(当前,在80%以上的农产品中都存在真菌毒素,而1985年仅为25%)。中国是农业生产大国,谷物产量居于世界之首,也是饲料生产和消耗大国,更应充分重视真菌毒素污染问题。常见的真菌毒素有玉米赤霉烯酮(ZEN)、脱氧雪腐烯醇(DON)、黄曲霉毒素(Aflatoxins)、赭曲霉毒素(Ochratoxins)、富马菌素(Fumonisins)等。全球主要饲料生产大国和地区都制定了真菌毒素限量标准,中国的一些检测标准甚至高于欧盟。

A simple commercial graphite pencil electrode was used to investigate the electrochemical oxidation of dopamine. The electropolymerised film of eriochrome black t was prepared on the surface of graphite pencil electrode by using cyclic voltammetry technique. The prepared electrode exhibits an excellent electrocatalytical activity towards the determination of dopamine. The effects of concentration, pH and scan rate were investigated. Simultaneous detection of dopamine and uric acid was investigated by using both cyclic voltammetric and differential pulse voltammetry technique. The modified electrode was also used for the detection of dopamine in injection.

Removal efficiency of phenol from aqueous solutions was determined using Pseudomonas putida (NCIM 2102). Experiments were made as a function of pH (4 - 9), temperature (28 - 36oC), and agitation speed (100 - 200 rpm). Optimization of these three process parameters for phenol degradation was studied. Statistically designed experiments using response surface methodology was used to get more information about the significant effects and the interactions between these three parameters. A 23 full-factorial central composite design was employed for experimental design and for analysis of the results. A second order polynomial regression model, has been developed using the experimental data. It was found that the degrading potential of *** (NCIM 2102) was strongly affected by the variations in pH, temperature and agitation speed. The experimental values were in good agreement with the predicted values and the correlation coefficient was found to be 0.9871. The optimum process conditions for maximizing phenol degradation were recognized as follows: pH (7.49), temperature (29.99oC), and agitation speed (138.89) rpm.
