Endotracheal tube cuff pressure during laparoscopic bariatric surgery: highs and lows
Saxena Dipti,Raghuwanshi Jyoti,Dixit Atul,Chaturvedi Subodh 대한마취통증의학회 2022 Anesthesia and pain medicine Vol.17 No.1
Background: Gastric calibration tubes (GCTs) are a unique component of bariatric surgery. This study aimed to assess changes in the endotracheal tube (ETT) cuff pressure during laparoscopic bariatric surgery.Methods: This was a prospective observational study consisting of 124 American Society of Anesthesiologists class I–III morbidly obese patients (body mass index > 40 kg/m2) undergoing elective laparoscopic bariatric surgery under general anesthesia. The baseline ETT cuff pressure was 28 cmH2O. Cuff pressure, peak airway pressure, and hemodynamic changes were observed during various steps of bariatric surgery. Immediate postoperative complications during the first 24 h were recorded. Results: ETT cuff pressure increased significantly from the baseline (28 cmH2O) after insertion of GCT (36.3 ± 7.3 cmH2O) and creation of carboperitoneum (33.3 ± 3.8 cmH2O). Cuff pressure decreased significantly on GCT removal (24.0 ± 3.0 cmH2O) and release of carboperitoneum (24.7 ± 3.0 cmH2O). Peak airway pressure increased from the initial baseline value of 25.1 ± 3.1 to 26.5 ± 4.5 after GCT insertion, creation of carboperitoneum (32.6 ± 4.4), attainment of reverse Trendelenburg position (32.3 ± 4.0), and subsequent return to supine position 32.5 ± 4.8.Conclusions: The endotracheal cuff pressure significantly varies during the intraoperative period. Routine monitoring and readjustment of cuff pressure are advisable in all laparoscopic bariatric surgeries to minimize the possibility of postoperative complications.

Design of Low Power and Secure Implementation of SBox and Inverse-SBox for AES
Divya Sharma,Ankur Bhardwaj,Harshita Prasad,Jyoti Kandpal,Abhay Saxena,Kumar Shashi Kant,Gaurav Verma 보안공학연구지원센터 2016 International Journal of Security and Its Applicat Vol.10 No.7
In the cutting edge world, data security has turned into an essential issue furthermore the innovation is going to increment quickly. In this paper, the symmetric key standard for encryption and decoding is propelled Encryption standard (AES). The key stride in the AES is the "S-Box". S Box is an imperative segment for symmetric key calculations. An S-box takes some number of information bits "p" and interprets them in yield bits 'q', where "p" is not as a matter of course equivalent to 'q'. In AES Encryption calculation Sub Bytes change uses S-Box and Inverse S-Box uses Inverse of S-Box. The Sub Bytes substitution is a nonlinear byte substitution that uses substitution table (i.e., S-Box) takes the multiplicative reverse (GF (28)) and infers a relative change to do the Sub Bytes change. Though, converse Sub Bytes Substitution additionally uses gaze upward table (i.e., Reverse S-Box) takes an opposite relative change and after that suggests multiplicative backwards of Galois Field (GF (28)). In this printed material, we investigated substitution table/reverse substitution table, multiplicative opposite and relative change and its converse (i.e. reverse relative change) science in Galois field. A standout amongst the most basic issues in AES is the force utilization. Here, we predominantly centered around the force utilization and in addition security of S-box which is the most power devouring square in the AES. We have executed and reproduced S-Box and Inverse S-Box Lookup table and acquired another improved scrambled Lookup table for more upgraded mystery by utilizing Xilinx Spartan-3 assessment board. The Simulation and execution instruments utilized are Xilinx ISE 14.1i and ModelSim 6.0.

The aim of the present study was to decipher the diversity of methanogens in rumen of Murrah buffaloes so that effective strategies can be made in order to mitigate methane emission from these methanogens. In the present study diversity of rumen methanogens in Murrah buffaloes (Bubalus bubalis) from North India was evaluated by using mcr-A gene library obtained from the pooled PCR product from four animals and by using MEGA4 software. A total of 104 clones were examined, revealing 26 different mcr-A gene sequences or phylotypes. Of the 26 phylotypes, 16 (64 of 104 clones) were less than 97% similar to any of the cultured strain of methanogens. Seven clone sequences were clustered with Methanomicrobium mobile and three clone sequences were clustered with Methanobrevibacter gottschalkii during the phylogenetic analysis. Uncultured group of methanogens comes out to be the major component of the methanogens community structure in Murrah buffaloes. Methanomicrobium phylotype comes out to be major phylotype among cultured methanogens followed by Methanobrevibacter phylotype. These results help in making effective strategies to check the growth of dominant methanogenic communities in the rumen of this animal which in turn help in the reduction of methane emission in the environment and ultimately helps us in fighting with the problem of global warming.
