Pecs-2

Background and study aims While gastric endoscopic submucosal dissection (ESD) has become a treatment with fewer complications, delayed bleeding remains a challenge. Post-ESD coagulation (PEC) is performed to prevent delayed bleeding. Therefore, we developed an artificial intelligence (AI) to detect vessels that require PEC in real time. Materials and methods Training data were extracted from 153 gastric ESD videos with sufficient images taken with a second-look endoscopy (SLE) and annotated as follows: (1) vessels that showed bleeding during SLE without PEC; (2) vessels that did not bleed during SLE with PEC; and (3) vessels that did not bleed even without PEC...

31P nuclear magnetic resonance (NMR) chemical shifts were shown to be very sensitive to the basis set used at the geometry optimization stage. Commonly used energy-optimized basis sets for a phosphorus atom containing only one polarization d-function were shown to be unable to provide correct equilibrium geometries for the calculations of phosphorus chemical shifts. The use of basis sets with at least two polarization d-functions on a phosphorus atom is strongly recommended. In this paper, an idea of creating the basis sets purposed for the geometry optimization that provide the least possible error coming from the geometry factor of accuracy in the resultant NMR shielding constants is proposed...

This study aimed to evaluate the efficacy of the pectoral nerves interfacial plane block (PECS II) in breast cancer surgery focusing on postoperative pain management and patient satisfaction. A prospective study was conducted, including 200 patients scheduled for breast cancer surgery. The participants were randomly assigned to the PECS II block and control groups. The PECS II block group received a preoperative interfascial plane block, while the control group received standard analgesia. Postoperative pain scores at 4 h intervals for the first 3 postoperative days, as well as opioid consumption and patient-reported satisfaction, were measured and compared between both groups...

The basis set issue has always been one of the most important factors of accuracy in the quantum chemical calculations of NMR chemical shifts. In a previous paper, we developed new pecS- n ( n = 1, 2) basis sets purposed for the calculations of the NMR chemical shifts of the nuclei of the most popular NMR-active isotopes of 1-2 row elements and successfully approbated these on the DFT calculations of chemical shifts in a limited series of small molecules. In this paper, we demonstrate the performance of the pecS- n ( n = 1, 2) basis sets on the calculations of as much as 713 1 H and 767 13 C chemical shifts of 23 biologically active natural products with complicated stereochemical structures, carried out using the GIAO-DFT(PBE0) approach...

Plants can bind excessive heavy metals by synthesizing compounds to alleviate the harm caused by heavy metals. To reveal the mechanism by which Dendrobium nobile alleviates zinc stress, metabolome combined transcriptome analysis was used in this research. The results showed that zinc was mainly enriched in the roots and leaves and the biomass of the roots and leaves of D. nobile decreased significantly by 18.21 % and 49.22 % (P < 0.05) compared to the control (CK), respectively...

Untreated group A Streptococcus (GAS) can lead to a range of life-threatening diseases, including rheumatic heart disease. To date, no therapeutic or prophylactic vaccines are commercially available to treat or prevent GAS infection. Development of a peptide-based subunit vaccine offers a promising solution, negating the safety issues of live-attenuated or inactive vaccines. Subunit vaccines administer small peptide fragments (antigens), which are typically poorly immunogenic. Therefore, these peptide antigens require formulation with an immune stimulant and/or vaccine delivery platform to improve their immunogenicity...

The basis sets that are used in the quantum chemical calculations of 31 P NMR chemical shifts have always been one of the most important factors of accuracy. Regardless of what high-quality approach is employed, using basis sets of insufficient flexibility in the important angular regions may give poor results and lead to misassignments of the signals in the 31 P NMR spectra. In this work, it was found that the existing nonrelativistic basis sets for phosphorus atom of double- and triple- ζ quality, specialized for the 31 P NMR chemical shifts calculations, are essentially undersaturated in the d -angular space that occurred to play a significant role in the overall accuracy of these calculations...

INTRODUCTION: Postoperative acute and chronic pain following breast surgery is a common complication which needs resolving to allow for improved patient outcomes. Previously thoracic epidurals and paravertebral blocks (PVB) have been the gold standard administered intra-operatively. However, more recently the introduction of the Pectoral nerve block (PECS and PECS-2 blocks) has looked promising to control the pain more effectively, but further robust analysis is required to prove its efficacy...

OBJECTIVE: Evaluate agreement between 2 non-invasive blood pressure (NIBP) techniques and invasive arterial blood pressure (IBP) in anesthetized bats using various cuff sizes and cuff positioning while also evaluating its performance during hypertension and hypotension. ANIMALS: 8 bats (1.1 ± 0.2 kg). PROCEDURES: Bats were anesthetized with isoflurane in oxygen. NIBP was measured using oscillometric (NIBP-O) and Doppler (NIBP-D) techniques in the pectoral limb (PEC) and pelvic limbs (PEL) using 3 cuff sizes (1, 2, and 3)...

BACKGROUND: Surgery for breast cancer is common, and intravenous opioids are often used to control postoperative pain. Recently, pectoralis-2 (PECS-2) block has emerged as a promising regional anaesthetic alternative. With nomenclature recently proposed, this block is termed combined PSP/IPP-block (pectoserratus plane block/interpectoral plane block). OBJECTIVE: We aimed to compare the need for postoperative rescue morphine between the intervention group that received a pre-operative combined PSP/IPP-block and a control group that received peri-operative long-acting opioids for postoperative analgesia...

This paper demonstrates the performance of our previously suggested property-energy consistent method on the example of the generation of effective basis sets, pecS-1 and pecS-2, suited for the calculation of hydrogen, carbon, nitrogen, and oxygen chemical shifts. The new basis sets were successfully approbated in the GIAO-DFT calculations of the chemical shifts of 35 molecules using six different functionals. The pecS-1 basis set demonstrated very good accuracy, which makes this small basis set an effective means for the large-scale computations...

Energy consumption efficiency is gaining momentum due to climate change, increased carbon emissions by firms, and paucity of fossil fuels. Energy management systems (EMS) and environmental awareness came into the spotlight few decades ago and are said to improve energy efficiency of firms. The purpose of this paper is to unveil the association and serial mediation between EMS and firm performance through pro-environmental energy consumption (PEC) and pro-environmental energy consumption performance (PECP), and the moderating role of environmental awareness (EA)...

INTRODUCTION: The aim of this study is to verify if the shoulder anterior capsular block (SHAC), combined with other nerve blocks, is effective in relieving shoulder pain, avoiding motor block and allowing an early rehabilitation program. METHODS: Seventy-five consecutive patients with painful shoulder were treated with the SHAC, alone (30 patients) or in combination with a suprascapular nerve block (SSnb: 25 patients) or with pectoralis and serratus plane block (PECS-2: 20 patients)...

INTRODUCTION: Women with preeclampsia are more likely to have abnormal echocardiographic parameters at the time of diagnosis and are more likely to have hypertension and other cardiovascular diseases (CVD) later in life. Screening for future CVD in preeclamptic women would assist in appropriately risk stratifying and identifying high risk women for preventive management; however, the timing of screening and the screening factors are unknown. OBJECTIVE: The objectives of this project are to 1) assess incidence of essential hypertension 4 years after pregnancy in preeclampsia with severe features (PEC) 2) identify predictive echocardiographic variables at the time of PEC diagnosis and 3) assess the rate of echocardiographic abnormalities 4 years after developing PEC...

The pectoral nerves 2 (pecs 2) block is widely used as adjunct to general anaesthesia for breast surgery. There are a few case reports and a single case series that describe regional anaesthesia as a single technique or supplemented by light to moderate sedation. Here we describe the management of a 91-year-old ASA physical status 4 patient who presented with a T4 breast malignancy. She was considered unfit for general anaesthesia due to significant valvular heart disease. A wide local excision was successfully performed under a pecs 2 block and a transverse thoracis plane block, supplemented with light sedation...
