Efficacy and safety of post-cesarean section incisional infiltration with lidocaine and epinephrine versus lidocaine alone in reducing postoperative pain: A randomized controlled double-blinded clinical trial.

Objective: Aim was to assess the efficacy and safety of incisional infiltration of lidocaine and epinephrine vs. lidocaine only to reduce postcesarean section (C/S) pain.

Material And Methods: It was a prospective, randomized, controlled, double-blinded clinical trial that was conducted in two tertiary hospitals in Egypt and included 153 women undergoing C/S under general anesthesia.

An interesting case of intramyometrial pregnancy.

A 27-year-old woman, gravida 3, para 1, at 9 weeks gestation, initially presented with clinical and ultrasonographic features suggestive of a missed spontaneous abortion for which surgical evacuation was performed. A diagnosis of ectopic pregnancy was made as on histological review no fetal or chorionic tissue was seen. Medical management for an ectopic pregnancy was initiated.

Impact of seroconversion and antichlamydial treatment on the rate of pre-eclampsia among Egyptian primigravidae.

Objective: To evaluate the effect of antichlamydial treatment and Chlamydia pneumoniae seroconversion on the incidence of pre-eclampsia among Egyptian primigravidae.

Methods: The present prospective study included 600 healthy normotensive primigravidae who attended an outpatient clinic at 10-16weeks of pregnancy. A single venous blood sample was collected to test for C.

Statistical mechanics of integral membrane protein assembly.

During the synthesis of integral membrane proteins (IMPs), the hydrophobic amino acids of the polypeptide sequence are partitioned mostly into the membrane interior and hydrophilic amino acids mostly into the aqueous exterior. Using a many-body statistical mechanics model, we analyze the minimum free energy state of polypeptide sequences partitioned into α-helical transmembrane (TM) segments and the role of thermal fluctuations. Results suggest that IMP TM segment partitioning shares important features with general theories of protein folding.
