Abstract. Sterner G, Carlson J, Ekberg G (Malmö University Hospital, Malmö, Sweden). Raised platelet levels in diabetes mellitus complicated with nephropathy. J Intern Med 1998; 244: 437-41.Objectives. To study if elevated platelet levels are found in early and late diabetic nephropathy. Design. A retrospective study was performed of platelet count in different subgroups of patients with insulindependent diabetes mellitus, including patients with long and short duration of diabetes and with early signs of nephropathy. Patients with severe renal failure subjected to renal transplantation were also included.
Results.The results suggest that raised platelet levels were associated with early signs of diabetic nephropathy and with female gender. Amongst diabetics progressing to uraemia leading to renal transplant, the platelet level was 50% higher than in non-diabetic uraemic patients. Conclusion. It is concluded that raised platelet levels are a common finding in patients with diabetes mellitus complicated by nephropathy.
Possibility of compact low loss analog type millimeter wave phase shifter was demonstrated. The phase shifter is controlled by a MEMS tunable high-impedance surface placed, e.g., as a backshort or as sidewall inclusions of a rectangular metal waveguide. Reflection type phase shifter can provide differential analog phase shift from 0 deg. to up to 240 deg. Reliable and tunable MEMS based high-impedance surface has been demonstrated for the first time. The insertion loss of the fabricated MEMS tunable high-impedance surface varies from 0.7 dB to a maximum of 3.5 dB (at a resonance frequency), which is a dramatic improvement over our previous non-tunable prototype.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
