BACKGROUND: Pectoral nerve block (PECS block) is first reported by Blanco et al, and mainly used for analgesia for breast surgery in Japan. However, the spread of PECS block is unclear. METHODS: Ultrasound guided PECS I and II blocks were performed in a cadaver, and the cadaver was dissected for evaluation of the spread of coloring matter. RESULTS: The coloring matter by PECS I block was spread to the axillary region between the major and minor pectoral muscles, while PECS II block remained over the fascia of the serratus muscle from mid-clavicular line to middle axillary line...

Pecs block and its variations have been used for various breast surgeries. We describe 2 cases of mastectomy and breast reconstruction by latissimus dorsi (LD) flap where regional analgesia was provided by a combination of ultrasound-guided Pecs-I block and serratus anterior plane block, a recently described technique in which local anesthetic is deposited in the plane between the LD and serratus anterior muscle. This resulted in excellent intraoperative and postoperative analgesia and a minimum of systemic analgesics...

BACKGROUND: The pectoral nerves (Pecs) block types I and II are novel techniques to block the pectoral, intercostobrachial, third to sixth intercostals, and the long thoracic nerves. They may provide good analgesia during and after breast surgery. Our study aimed to compare prospectively the quality of analgesia after modified radical mastectomy surgery using general anesthesia and Pecs blocks versus general anesthesia alone. METHODS: One hundred twenty adult female patients scheduled for elective unilateral modified radical mastectomy under general anesthesia were randomly allocated to receive either general anesthesia plus Pecs block (Pecs group, n = 60) or general anesthesia alone (control group, n = 60)...

PETRORISK is a modeling framework used to evaluate environmental risk of petroleum substances and human exposure through these routes due to emissions under typical use conditions as required by the European regulation for the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH). Petroleum substances are often complex substances comprised of hundreds to thousands of individual hydrocarbons. The physicochemical, fate, and effects properties of the individual constituents within a petroleum substance can vary over several orders of magnitude, complicating risk assessment...

Plasmonic photoelectrochemical (PEC) water splitting is very promising in the conversion of abundant solar energy into chemical energy. However, the solar-to-hydrogen efficiencies reported so far are still too low for practical use, which can be improved by optimizing the design and synthesis of individual blocks (i. e., the compositions, sizes, shapes of the metal and the coupling semiconductors) and the assembly of these blocks into targeted three-dimensional (3D) structures. Here, we constructed a composite plasmonic metal/semiconductor photoanode by decorating gold nanoparticles (Au NPs) on 3D branched ZnO nanowire arrays (B-ZnO NWs) through a series of simple solution chemical routes...

PURPOSE: We previously reported that importin 13 (IPO13), a member of the importin-β family of nuclear import proteins, regulates nuclear import of the glucocorticoid receptor in airway epithelial cells, IPO13 serves as a potential marker for corneal epithelial progenitor cells, and IPO13 is associated with corneal cell proliferation. Here we investigated the role of IPO13 in the pathogenesis of pterygium and the underlying mechanism including interaction with other cell proliferation-related factors: keratin 17 (K17), a lesional protein and a member of the type I keratins, and c-Jun, a protein of the activator protein-1 complex...

OBJECTIVE: The Pecs block (pectoral nerves block) is an easy and reliable superficial block inspired by the infraclavicular block approach and the transversus abdominis plane blocks. Once the pectoralis muscles are located under the clavicle the space between the two muscles is dissected to reach the lateral pectoral and the medial pectoral nerves. The main indications are breast expanders and subpectoral prosthesis where the distension of these muscles is extremely painful. MATERIAL AND METHODS: A second version of the Pecs block is described, called "modified Pecs block" or Pecs block type II...

BACKGROUND: Asthma and chronic obstructive pulmonary disease are characterized by inappropriate constriction of the airway smooth muscle. In this context, the physiological response of the human airways to selective relaxant agonists like PGE(2) is highly relevant. The aim of this study was thus to characterize the PGE(2) receptor subtypes (EP(2) or EP(4)) involved in the relaxation of human bronchial preparations. METHODS: Human bronchial preparations cut as rings were mounted in organ baths for isometric recording of tension and a pharmacological study was performed using selective EP(2) or EP(4) ligands...

Di-block copolymer polystyrene-block-polymethyl methacrylate (PS-b-PMMA) was used to make patterns over a large area of as grown LEDs. The polymer patterns on LEDs surface could be transferred to the underlying p-GaN, the topmost layer of as grown LEDs by both reactive ion etching (RIE) and photo-enhanced chemical (PEC) etching. Removal of remaining polymer chains results in patterned LEDs which shows higher light extraction efficiency. In our experiment, much higher intensity for patterned LEDs in both photoluminescence (PL) and electroluminescence (EL) data plot were found...

Neonicotinoid insecticides, such as imidacloprid, are selective agonists of the insect nicotinic acetylcholine receptors (nAChRs) with -NO(2) or -CN group in trans-configuration. Previously we reported the excellent insecticidal activity of a series of nitroconjugated neonicotinoids with -NO(2) or -CN group in cis-configuration by replacing nitromethylene pharmacophore with a nitroconjugated system. To understand the action mode of these nitroconjugated neonicotinoids, a representative member IPPA152201 was chosen to perform toxicity and pharmacology studies...

The human Ether-à-go-go related gene (hERG) potassium channel is responsible for the rapid delayed rectifier potassium current that plays a critical role in the repolarization of cardiomyocytes during the cardiac action potential. In humans, inhibition of hERG by drugs can prolong the electrocardiographic QT interval, which, in rare instance, leads to ventricular arrhythmia and sudden cardiac death. As such, several medications that block hERG channels in vitro have been withdrawn from the market due to QT prolongation and arrhythmias...

The adsorption characteristics of two different types of polyelectrolyte complexes (PECs), prepared by mixing poly(allylamine hydrochloride) and poly(acrylic acid) in a confined impinging jet (CIJ) mixer, have been investigated with the aid of stagnation point adsorption reflectometry (SPAR), a quartz crystal microbalance with dissipation (QCM-D), and atomic force microscopy (AFM) using SiO(2) surfaces. The two sets of PEC were prepared by combining high molecular mass PAH/PAA (PEC-A) and low molecular mass PAH/PAA (PEC-B)...

Strains of influenza A virus show marked differences in their ability to infect murine macrophages (MPhi) such that strain A/PR/8/34 (PR8; H1N1) infects MPhi poorly while strain BJx109 (H3N2) infects MPhi to high levels. Given the central role of MPhi in initiating and regulating inflammatory responses, we hypothesized that virus strains that infect MPhi poorly may also be poor at initiating inflammatory responses. Studies to compare the inflammatory response of mice after intranasal inoculation with either BJx109 or PR8 were confounded by the rapid growth of the PR8 virus in lung tissues...

beta(3)-adrenoceptor activation produces relaxation of human urinary bladder smooth muscle (detrusor). Therefore, beta(3)-adrenoceptor agonism is being investigated as a new therapeutic strategy for the treatment of overactive bladder. The aim of the current study was to identify the functional presence of beta(3)-adrenoceptors in mouse isolated urinary bladder using the selective beta(3)-adrenoceptor agonist CL316,243 and antagonists SR59230A and L748,337. The effects of CL316,243 on basal tone, spontaneous activity and electrical field stimulation (EFS)-induced contractions were investigated using in vitro techniques, while the in vivo effects of intravenously administered CL316,243 on the micturition reflex were investigated using cystometry...
