Family Pets as a Source of Microspoum canis Infection
엠 팔,에스 엠 다히야,이창우,Pal M.,Dahiya S.M.,Lee Changs-Woo The Korean Society of Veterinary Clinics 1990 한국임상수의학회지 Vol.7 No.2
Microspoum canis에 감염된 개 및 고양이와 직접 접촉한 경험이 있는 5명의 환자를 조사하여 동물기생체로서의 이 진균의 중요성을 확인하였다. ring worm의 전형적인 병변은 신체의 노출된 부위에만 발생하였다. M. canis는 환자와 감염된 애완동물의 피부병변에서 분리되었으며 피부 시료로부터 직접 증명되었다. 그림에도 불구하고 비접촉군과 사물성환경으로 부터는 증명되지 않았다. 사람, 개 및 고양이에서 분리된 진균들은 육안적으로나 현미경적으로 서로 비슷한 형태를 나타내었다. 이 진균들의 유전학적 연구결과는 교배(-)형이었다. 동물기호성 표재성진균의 전염은 직접적인 접촉에 의해 자주 일어나는 것으로 사료된다. 이감염증에 대한 역학과 예방방법에 대해 고찰하였다. The present investigation confirms the zoonotic significance of Microspoum canis infection in five patients who had direct contact with diseased dogs and cats. Typical ringworm type lesions were mainly encountered on the exposed areas of the body. M. canis was isolated from the cutaneous lesions of man ana infected pets ; and also directly demonstrated in skin materials. However, the fungus could neither be recovered from the non-contact group nor from the saprobic environment. The isolates from man, dog, and cat showed similar gross as well as microscopic morphology. Further genetic studies so indicated that all the human and animal isolates of M. canis were(-) mating type. It is believed that transmission of zoophilic dermatophytes from animal to man occurs more commonly with direct exposure. In addition, the epidemiology and preventive measures are also discussed.

Biswajit Mishra, M.D.,Kumble Seetharama Madhusudhan, M.D., FRCR,Ragini Kilambi, M.Ch.,Prasenjit Das, M.D.,Sujoy Pal, M.Ch.,Deep Narayan Srivastava, M.D. 대한흉부외과학회 2016 Journal of Chest Surgery (J Chest Surg) Vol.49 No.1
Neurogenic tumors are the most prevalent tumors of the mediastinum, and schwannomas are the most common type of neurogenic tumor. Primary neurogenic neoplasm of the esophagus is uncommon and malignant schwannoma of the esophagus is extremely rare. We report a case of a 27-year-old female presenting with dysphagia and palpitations who was found to have a lobulated tumor in the mediastinum that was compressing the esophageal lumen. The tumor was successfully treated surgically without recurrence. The final diagnosis, on histopathological examination of the specimen, was malignant schwannoma.

<P>We have searched for the Cabibbo-suppressed decay Lambda(+)(c) -> pi p(0) in e(+) e(-) collisions using a data sample corresponding to an integrated luminosity of 915 fb(-1). The data were collected by the Belle experiment at the KEKB e(+) e(-) asymmetric-energy collider running at or near the (4S) and (5S) resonances. No significant signal is observed, and we set an upper limit on the branching fraction of B(Lambda(+)(c) -> phi p(0)) < 15.3 x 10(-5) at 90% confidence level. The contribution of nonresonant Lambda(+)(c) -> K+ K- p pi(0) decays is found to be consistent with zero, and the corresponding upper limit on its branching fraction is set to be B(Lambda(+)(c) ->. K+ K- p pi(0))(NR) < 6.3 x 10(-5) at 90% confidence level. We also search for an intermediate hidden-strangeness pentaquark decay P-s(+) -> phi p. We see no evidence for this intermediate decay and set an upper limit on the product branching fraction of B(Lambda(+)(c) -> P-s(+) pi(0)) x B(P-s(+) -> phi p) < 8.3 x 10(-5) at 90% confidence level. Finally, we measure the branching fraction for the Cabibbo-favored decay Lambda(+)(c) -> K- pi(+) p pi(0); the result is B(Lambda(+)(c) -> K- pi(+) p pi(0)) = (4.42 +/- 0.05(stat)+/- 0.12(syst)+/- 0.16(norm))%, which is the most precise measurement to date.</P>
EFFECT OF Mn DOPING ON MICROSTRUCTURE AND OPTICAL PROPERTIES OF NANOCRYSTALLINE ZnO
M. KARMAKAR,O. MONDAL,B. ROY,P. K. PAUL,M. PAL 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2013 NANO Vol.8 No.6
Mn-doped ZnO has emerged as the most studied system for prototype applications in spintronics devices because of its interesting magnetic properties. In this report, nanocrystalline ZnO doped with various concentration of Mn have been synthesized from different precursors using modified ceramic route. Samples are characterized by using X-ray diffractometer (XRD), high resolution transmission electron microscopy (HRTEM) and UV-Vis spectrophotometer. XRD and HRTEM studies confirm the growth of single phase, well crystallized Mn-doped ZnO nanoparticles. Particle size estimated from Rietveld analysis as well as TEM images show a decreasing tendency with the increase in Mn concentration. We observe both band bowing and red shift in optical bandgap by varying the concentration of Mn and precursors. This study demonstrates that Mn concentration is not the only factor but precursors have a definite role on the variation of optical bandgap.

Changes in biochemical constituents and physiological alteration were studied in various intensities (1-5%, 6-15%, 16-30%, 31-50% and > 50%) of leaf spot (Myrothecium roridum) on mulberry leaves and compared with healthy leaves. Chlorophyll, total soluble sugar and total protein were decreased (P < 0.01), but total phenol increased due to pathogen infection. Changes in biochemical constituents showed significant correlation with intensity of disease. Chlorophyll ($r^2$= 0.92), and protein (($r^2$= 0.83) possessed negative while phenol (($r^2$= 0.61) possessed positive correlation. Photosynthetic rate, transpiration rate, stomatal conductance, moisture content (%) and physiological water use efficiency (pWUE) were decreased, but stomatal resistance increased in the infected leaves. Physiological parameters also possessed significant (P < 0.01) correlation with disease intensity. Photosynthetic rate (($r^2$= 0.96), transpiration rate ($r^2$=0.88), stomatal conductance (($r^2$= = 0.65), physiological water use efficiency (($r^2$= 0.88) and moisture content (r = 0.85) were negatively but stomatal resistance (($r^2$= 0.75) was positively correlated to disease intensities.

Kumar, P.M.Pratheesh,Pal, S.C.,Qadri, S.M.H.,Gangwar, S.K.,Saratchandra, B. Korean Society of Sericultural Science 2003 International Journal of Industrial Entomology Vol.6 No.2
Studies were conducted on the effect of pruning time, host age, conidial dispersal and weather parameters on the incidence and severity of mulberry leaf spot (Myrothecium roridum). The disease severity (%) increased with increase in shoot age irrespective of pruning date. Maximum disease severity was observed in plants pruned during first week of April and minimum disease severity in plants pruned during first week of March. Significant (P < 0.01) influence of date of pruning, shoot age and their interaction was observed on severity of the disease. Apparent infection rate (r) was significantly higher during the plant growth period from day 48 to day 55. Average apparent yale was higher in plants pruned during first week of April and least in plants pruned during first week of July. The disease infection was negatively correlated to distance from the inoculum source. Leaf spot severity (%) was influenced by weather parameters. Multiple regression analysis revealed contribution of various combinations of weather parameters on the disease severity. Linear prediction model $(Y = -81.803+1.176x_2+0.765x_3) with significant $R^2$ was developed for prediction of the disease under natural epiphytotic condition.

<P>A novel electrochemical sensor was fabricated by simply screen printing reduced graphene oxide (rGO) paste on F-doped tin oxide (FTO) (rGO-SP-FTO) followed by sintering at 450 degrees C in Argon and employed for detecting dopamine (DA) and uric acid (UA) simultaneously. The rGO film was characterized by using Raman spectroscopy, field emission scanning electron microscope (FE-SEM), and Fourier transform infrared spectroscopy (FTIR). The surface sensing features of rGO-SP-FTO were studied with electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV). The rGO-SP-FTO electrode exhibited foremost sensitivity in simultaneous detection of DA and UA without any interference from ascorbic acid (AA). The rGO-SP-FTO electrode showed a good linear response in the range of 0.5-50.0 mu M and 5.0-300 mu M with detection limits (S/N = 3) of 0.07 mu M and 0.39 mu M for DA and UA, respectively. The interactions between screen printed rGO with FTO electrode and their influence on how rGO-SP-FTO electrode interacted with UA, DA, and AA were analyzed from experimental observations. The rGO-SP-FTO electrode was able to detect DA in dopamine hydrochloride injection (DAI) and UA in urine sample effectively. Moreover, the designed electrochemical sensor exhibited excellent stability and reproducibility. (C) 2018 The Electrochemical Society.</P>
