The band called amide A is available in all the diseased and healthy controls and the frequency of the band ranges from 3380 cm﹣1 to 3480.74 cm﹣1. The band due to C-H band and called hydrocarbon band was found only in paralytic and Alzheimer diseased along with normal healthy controls. Carbide band (C=C) is found only in Duchenne muscular dystrophy, paralytic and Alzheimer’s disease patients. Amide I was intact in all disorders with normal persons. Peroxide band (O-O) was found in all the cases of study. Amide IV band was found in paralytic, muscular dystrophy, Alzheimer’s diseases and normal controls. The amide V band was found in Alzheimer’s diseases only. The appearance or disappearance of the bands is a good sign to understand the mechanisms at the molecular level. FTIR spectroscopy may help in the diagnosis of the disease at the early stage of the onset. This spectroscopy can be used nicely for the study of hair, vaginal fluid, nails, urine, mucus, semen, synovial fluid, blood, hemoproteins, skin, and tears for human beings. We can also use it to understand the effect of adulteration on food and paint technology. FTIR is an indicator to explore the changes occurring at molecular level.展开更多

Various general considerations as well as specific examples are given to illustrate and support our arguments. These examples range from the practical aspect to almost esoteric considerations but at the end, everything converges towards a unity of theory and computation presented in the form of modern fractal logic and transfinite quantum field theory in a Cantorian spacetime. It is true that all our examples are taken from physics but our discussion is applicable in equal measure to a much wider aspect of life.展开更多

Purpose: To find the effect of lumbrokinase (LK) on P-selectin and E-selectin in ischemic rats.

Methods: Male healthy Spragur-Dawley rats weighing 180-220 g (n=90) were divided into 4 groups: (1) normal control group (n=5), (2) sham-operated group (n=35), (3) ischemic group (n=35), (4) LK group (n=15). LK 10mg/kg (2000UK activity of LK) was given by intraperitoneal injection in the LK group 30 minutes before experiment. Same volume of normal saline was given in the sham-operated group and ischemic group. The ischemic model was made by modified Haruo Nagasawa's method. Immunohistochemistry was used to observe the P-selectin and E-selectin positive cells in the ischemic region. Results: P-selectin and E-selectin positive cells in ischemic regions were observed in the ischemic group, and the peak of expression was at 6 hours and 12 hours, respectively. The similar changes were not observed in normal control group. There were only a few positive cells in the sham-operated group. In LK group, the P-selectin and E-selectin positive cells were significantly less than those in the ischemic group (P<0.05 at 3 hours after the onset, P<0.01 at 6 hours and P<0.01 at 12 hours, respectively). Conclusions: LK might significantly decrease the immunoreactions of P-selectin and E-selectin in ischemic lesion.展开更多

We investigated the significance of stream processes in regulating P loading to the Cannonsville watershed, NY, USA. A mass balance of estimated P inputs to the stream with observed P export at the watershed outlet was used to quantify P delivery and explore the behavior of P. Stream channel transport of both dissolved and particulate P is found to be non-conservative, with dissolved P being retained during low flows and particulate P released during high flows. The results suggest that differences in the magnitude and relative importance of in-stream biogeochemical processes under different flow regimes regulate P delivery in ways that may influence ecological impacts to downstream river reaches and reservoirs.展开更多

When both rolling depth and ploughing-extrusion(P-E) depth were 0.2 mm,rotating speed was 50 r/min,feed speed was 0.16 mm/r,3D fin structures with height of 0.25 mm were gotten. Two different fin structures were obtained in grooves formed with rolling-ploughing-extrusion compound forming technology and observed by scanning electron microscope(SEM). One is the compound structure with V-shaped groove and U-shaped groove,and the other is the single structure with V-shaped grooves. Two kinds of groove structures obtained by rolling processing and ploughing extrusion processing are restricted together by groove interval and rolling depth,and pitch and P-E depth,respectively. Based on the analysis of interaction of rolling and P-E processing,it is found from the result that the outside 3D integral-fin can be achieved by rolling-ploughing-extrusion compound processing when single V-shaped groove structures are formed by both rolling and P-E processing.展开更多
