Bijan Mohammadhosseini
INTRODUCTION: Trocar dislodgment can occur frequently during minimally invasive surgery. Closing the entry port at the fascial layer after the end of a long laparoscopic surgery is time-consuming. Here, I introduce Tehran's Tie, a simple trick to overcome these problems. MATERIALS AND SURGICAL TECHNIQUE: After the first trocar site has been created with the open technique and before the first port is inserted, the fascial wound is grasped with a loop of nylon thread, similar to a transverse matrix suture...

Lumbar spinal stenosis is typically a degenerative condition that leads to compression of the spinal canal and lateral recess, resulting in leg pain and walking disability. Surgical management is indicated after failure of non-surgical management or rapidly worsening neurological impairment. The traditional approach is a laminectomy with foraminotomy and partial facetectomy but a newer minimally invasive option, unilateral laminectomy for bilateral decompression (ULBD), seems to demonstrate the better postoperative outcomes due to its unilateral exposure...

BACKGROUND AND PURPOSE: Naturally occurring dysfunction in NaV channels results in complex disorders such as chronic pain, making these channels an attractive target for new therapies. In the pursuit of novel NaV modulators, we investigated spider venoms for new inhibitors of NaV channels. EXPERIMENTAL APPROACH: We used high-throughput screens to identify a NaV modulator in venom of the spider Davus fasciatus. Further characterization of this venom peptide was undertaken using fluorescent and electrophysiological assays, molecular modeling and a rodent pain model...

In human neonates rapid adaptation from an aqueous intrauterine environment to permanent air breathing is the rate-limiting step for extrauterine life, failure of which justifies the existence of neonatal intensive care units. The lung develops at about 4-6 weeks' gestation in humans as a ventral outpouching of the primitive foregut into the surrounding ventral mesenchyme, termed the laryngotracheal groove. At its posterior end lie progenitor cells that form a pair of bronchial tubes, from which arise all the distal epithelial structures of the lung...

CD2 is expressed on the surfaces of virtually all T cells and natural killer (NK) cells. In mammals, the CD2 molecule is 50 kDa. The cytoplasmic tail of CD2 interacts with CD2-associated protein (CD2AP), which plays an important role in mediating the trigger signal in outer magnetic pole cells. In this study, we identified CD2AP from rock bream and investigated its gene expression. The ORF of CD2AP (1950 bp) encodes 650 amino acids (aa). CD2AP has a Src homology 3 (SH3) domain. Quantitative real-time PCR analysis revealed that CD2AP shows higher expression in the gills and skin...

Fascial Manipulation(®) (FM) is a manual therapy approach for the treatment of musculoskeletal pain. Anomalous fascial tension is common following surgery due to surgical scar, inadequate mobility and fear of movement. Fascial tension may result in pain and loss of mobility. This case report aims at investigating the effectiveness of FM(®) on pain and function in a patient following knee surgery. A 32 years old male patient, with persisting knee pain following anterior cruciate ligament reconstruction (hamstring graft) and meniscal repair, underwent the systematic FM(®) assessment process, the selected centers of coordination of myofascial units were treated...

Lactose intolerance is the decreased ability to digest lactose, and the population involved is rapidly increasing all over the world. Different procedures have been reported in the literature to quantify lactose in dairy products, but the official method of analysis is based on enzymatic assay. In this paper, the effectiveness of two enzymatic kits in detecting residual lactose in lactose-free milk was investigated, and a comparison with two alternative chromatographic methods was done. The investigation used several samples of UHT milk containing different levels of lactose, and the results highlighted the inadequacy of the enzymatic assays and of the HPLC-RI method to analyse lactose-free milk...

Black rockfish (Sebastes schlegelii), an important aquaculture species in Korea, has been affected by bacterial diseases leading to a drastic decline in production. Goose-type lysozyme (LysG) is a key enzyme of the innate immune system to eradicate bacterial infections. In this study, two isoforms of LysG from black rockfish, designated as RfLysG1 and RfLysG2, have been identified and characterized at the molecular, transcriptional, and functional levels. The deduced amino acid sequences had the LysG family characteristics and exhibited conserved properties, including active residues and domains...

Hernia is described as the protrusion of an organ into the wall of its normal containing cavity. Internal hernia (IH) involves protrusion of viscera through: a peritoneal or mesentery defect, a normal or abnormal compartment of the peritoneal cavity. Hernias occurring in the pelvis cavity are usually classified according to the fascial margins breached and include sciatic, obturator and those through the rectouterin pouch: elytrocele and enterocele. Those hernias are defined by the protrusion of a viscus through the wall of the pelvis due to weakness of the pelvic fascia and/or muscles...
