BACKGROUND Pre-pregnancy care is considered as the services assessing and reducing the pregnancy risks through providing medical care and mental support. Therefore, a pre-pregnancy counseling protocol was prepared based on a series of guidelines. This study aimed to determine the effect of the protocol on pregnancy and labor indices. METHODS This was a four-phase field study conducted in four...
Analysis of catecholamines (epinephrine, norepinephrine and dopamine) in plasma and urine is used for diagnosis and treatment of catecholamine-producing tumors. Current analytical techniques for catecholamine quantification are laborious, time-consuming and technically demanding. Our aim was to develop an automated on-line solid phase extraction method coupled to high performance liquid chromat...
BACKGROUND Blood transfusion chain can be divided into three phases: preanalytical (patient bedside), analytical (steps done at transfusion services), and postanalytical (bedside). Majority (~70%) of events due to blood transfusion have been attributed to errors in bedside blood administration practices. Survey of bedside transfusion practices (pre-analytical and post analytical phase) was done...
Background and Aim: Thalassemia major (ThM) is one of the most common autosomal recessive genetic disorders in the world. Its prevention and control is a priority in the disease prevention programs in the Iranian health system. The ThM screening program (screening at the time of marriage) has been an important step in its prevention in Iran. This study aimed to evaluate this program. Materia...
Intraplatelet phospho-VASP analysis is a commonly used approach for monitoring of anti-platelet therapy; however, testing of intraplatelet phospho-VASP expression needs a high level of experience and proficiency. The ability to recognize how the pre-analytical variations can change the results would be helpful for the interpretation of data from intraplatelet P-VASP analysis. The aim of this st...
Coculturing multiple cell types together in 3-dimensional (3D) cultures better mimics the in vivo microphysiological environment, and has become widely adopted in recent years with the development of organ-on-chip systems. However, a bottleneck in set-up of these devices arises as a result of the delivery of the gel into the microfluidic chip being sensitive to pressure fluctuations, making gel...
