How Might Consideration of Cell Polarity Affect Daily Therapeutic Practices?A Literature Review:

Background: In addition to biochemical gradients and transcriptional networks, cell behaviour is controlled by endogenous bioelectrical signals resulting from the action of ion channels and pumps. Cells are regulated not only by their own membrane resting potential (Vmem) but also by the Vmem of neighbouring cells, establishing networks through electrical synapses known as gap junctions. V mem is the primary factor in producing a polarity that can regulate cell assimilation of various substances.

Analgesic efficacy of local versus proximal nerve blocks after hallux valgus surgery: a systematic review.

Background: Hallux valgus (HV) surgery is an orthopaedic procedure that commonly causes mild to moderate postoperative pain. Effective management of this pain has become an important element of modern hallux valgus surgical treatment. A local anaesthetic (LA) with an antinociceptive effect can control this pain.

Perinatal outcome in pregnancy with polyhydramnios in comparison with normal pregnancy in department of obstetrics at Shiraz University of Medical Sciences.

Objective: Polyhydramnios can lead to maternal and fetal complication during pregnancy, so diagnosis and management can decrease some perinatal complications.

Study Design: One hundred and fourteen singleton pregnancies were diagnosed with idiopathic polyhydramnios in the department of obstetrics at Shiraz University of Medical Sciences between January 2000 and January 2011 and were compared with 114 normal pregnancies for their perinatal outcome. Variables include birth weight, admission to neonatal intensive care unit (NICU), meconium staining, respiratory distress, fetal death, neonatal death, low 1-min and 5-min APGAR score, primary cesarean section (C/S), preterm delivery (<37 weeks), postpartum bleeding, and placental abruption.

Comparison of Abnormal Cervical Cytology from HIV Positive Women, Female Sex Workers and General Population.

Background: Sex workers and HIV seropositive women are at high risk of abnormal cervical cytology. The objective of this study was to compare the cervical cytology among three groups of women: active sex workers, HIV-infected women, and general population in Iran.

Methods: This was a cross-sectional study performed in Hazrat Zeinab, Lavan clinics and drop in center (DIC) in Shiraz, Iran.
