To serve you better

Fasting blood lipids were analyzed shortly before revascularization surgery in an attempt to find a possible correlation between the fate of the aortocoronary saphenous vein graft and lipoproteinemia. The patency of the bypass was evaluated by arteriography at two weeks and at one year following operation. Patients with closed grafts at two weeks had an original mean serum triglyceride concentration of 287 mg./100 ml. Patients with grafts which were widely patent after one year had an original triglyceridemia of 224 mg./100 ml. The severely stenosed group had an intermediate average preoperative value of 224 mg./100 ml. The same conclusion was reached with a group of patients with good vessel(s) distal to the graft(s). Cholesterolemia was about the same in all groups. These results suggest the hypothesis that hypertriglyceridemia plays a significant role in the reduction and/or occlusion of the lumen of the vein graft.     

Me write pretty one day: how to write a good scientific paper

The scientific literature is exploding in quantity even as it stands still in literary quality. In this brief guide, I suggest a few small steps that the individual can take to make his or her writing clear, straightforward, and digestible.     

Using dBASE to write PENNAME, a computer key to common Penicillium species

dBASE III Plus™ computer software includes a high level computer language as well as a database management program. dBASE possesses advantages for key construction, including simple entry of raw data, effective user interaction in the selection of outputs, and ready comparison of included species with unknowns. This paper describes the use of dBASE in the construction of PENNAME, a new computer key to common Penicillium species.
