In wireless sensor networks (WSN), conserving energy is usually a basic issue, and several approaches are applied to optimize energy consumption. In this article, we adopt feature selection approaches by using minimum redundancy maximum relevance (MRMR) as a feature selection technique to minimize the number of sensors thereby conserving energy. MRMR ranks the sensors according to their significance.

Context: Models for predicting individual risks of surgical complications are advantageous for operative decision making and the nature of postoperative management procedures.

Objective: Validate the "ACS NSQIP Risk Calculator" in the prediction of postoperative complications during colorectal cancer surgery, operated during the years 2015 to 2019.

Methods: this is a prognostic validation study of the "ACS NSQIP" applied retrospectively to patients operated on for colorectal cancer in the surgical department of Farhat Hached hospital, during the 2015 and 2019 5-year term.

Article Synopsis
  • * This patient presented with a non-metastatic antral sarcomatoid carcinoma which grew quickly; despite surgery and initial negative margins, a local recurrence occurred within four months.
  • * The case emphasizes the need for timely surgical intervention in sarcomatoid carcinoma due to its aggressive nature and high risk of recurrence, although the effectiveness of peri-operative treatment remains unclear.

Purpose: To analyze vascular reactivity changes in response to immunization protocols with antigens corresponding to the second extracellular loop of -β3 and -β1 and 3 adrenergic receptors (AR).

Methods: Lewis rats were immunized for 3months with peptidic sequences corresponding to the second extracellular loop of β3-AR or β1 and 3-AR. Specific β3-AR antibodies were characterized by Elisa and purified using "Proteus Protein G" kit.
