We propose and demonstrate an experimental implementation for the observation of magnetic fields from spatial features of absorption profiles in a warm atomic vapor.A radially polarized vector beam that traverses atomic vapor will generate an absorption pattern with a petal-like structure by the mediation of a transverse magnetic field(TMF).The spatial absorption pattern rotates when the azimuthal angle of the TMF is changed,while its contrast decreases when the longitudinal component of the magnetic field *** analyzing the intensity distribution of the transmitted pattern,we can determine the magnetic field *** work provides a framework for investigating 3 D magnetic field distributions based on atoms.

AIM:To review an evolution of laparoscopic surgery,there has been a growing interest in laparoendoscopic single-site surgery(LESS).METHODS:A comprehensive electronic literature search was conducted using PubM ed database to identify all publications relating to LESS-partial nephrectomy(PN).The research includes articles published from April 2008 to January *** focused our attention only on articles in which were cited the single-site surgical technique(laparoscopic and robotic),tumour stage and grade,mean tumour size,intraoperative variables,blood loss and transfusion rate,length of postoperative stay and complication rates,Clavien classification,positive of surgical margins,pain assessment at ***:A total of 9 studies were collected with 221patients *** mean patients age was 62 *** mean tumor size was 2.35 cm with a mean operative time of 181 min(range 111-270 min)and 58.3%were done by *** mean ischemia time was *** 25.8%of patients underwent an unclamp *** estimated blood loss was 296 mL and median length of hospital stay was 4 *** rate of severe post-operative complications(≥Clavien gradeⅢ)was 5.4%.Not all surgical series of LESS-PN or Robotic-LESS-PN shows conversion in Multiport Laparoscopic or Open *** oncologic outcomes,surgical margins were positive 4%of patients(9/221),no distant or port-site metastases were ***:LESS-PN and RLESS-PN are feasible and associated with reduced postoperative pain,shorter median hospital stay,shorter recovery time,and better cosmetic satisfaction without compromising surgical and oncological safety.
