INTRODUCTION: Open chest surgery (thoracotomy) is considered the most painful of surgical procedures. Forceful wound retraction, costochondral dislocation, posterior costovertebral ligament disruption, intercostal nerve trauma and wound movement during respiration combine to produce an acute, severe postoperative pain insult and persistent chronic pain many months after surgery is common. Three recent systematic reviews conclude that unilateral continuous paravertebral blockade (PVB) provides analgesia at least equivalent to thoracic epidural blockade (TEB) in the postoperative period, has a lower failure rate, and symptom relief that lasted months...

We present an efficient implementation of dynamically pruned quantum dynamics, both in coordinate space and in phase space. We combine the ideas behind the biorthogonal von Neumann basis (PvB) with the orthogonalized momentum-symmetrized Gaussians (Weylets) to create a new basis, projected Weylets, that takes the best from both methods. We benchmark pruned time-dependent dynamics using phase-space-localized PvB, projected Weylets, and coordinate-space-localized DVR bases, with real-world examples in up to six dimensions...

The complete bipartite genome (RNA1 and RNA2) of a new nepovirus infecting potato was obtained using small RNA sequencing and assembly complemented by Sanger sequencing. Each RNA encodes a single polyprotein, flanked by 5' and 3' untranslate regions (UTR) and followed by a poly (A) tail. The putative polyproteins encoded by RNA1 and RNA2 had sets of motifs which are characteristic of viruses in the genus Nepovirus. Sequence comparisons using the Pro-Pol region and the coat protein, including phylogenetic analysis of these regions, showed closest relationships with nepoviruses...

BACKGROUND AND OBJECTIVES: The impact of regional anesthesia on breast cancer recurrence is controversial. We tested the hypothesis that the use of paravertebral block (PVB) analgesia during breast cancer surgery prolongs the recurrence-free survival (RFS) and overall survival (OS) of women with breast cancer. METHODS: Seven hundred ninety-two women with nonmetastatic breast cancer were included in this retrospective study. Patients were divided based on the administration of PVB analgesia for mastectomy surgeries...

We retrospectively assessed the effectiveness and the safety of thoracic paravertebral block(PVB) in patients ineligible for epidural block (EP). Eleven PVB patients and 33 EP patients were enrolled. Postoperative pain was evaluated using a numerical rating scale (NRS). The mean NRS ± standard deviation at rest 24 and 48 hours after surgery were 1.36 ± 1.63 and 0.55 ± 1.03 in the PVB group and 1.07 ± 1.47 and 1.38 ± 1.31 in the EP group, respectively. There were no statistically significant differences in the NRS scores...

PURPOSE: Retrolaminar block (RLB) is a thoracic truncal block that can produce analgesia for the thoracic and abdominal wall. However, the characteristics of RLB are not well known. The aim of this study was to determine analgesic efficacy by measuring postoperative consume of patient-controlled analgesia (PCA), additional nonsteroidal antiinflammatory drug (NSAID) rescue, and opioid rescue. Our secondary analysis included assessment of the chronological change in arterial levobupivacaine concentrations after the block...

BACKGROUND AND AIMS: Unilateral paravertebral block (PVB) as a sole anaesthetic technique is underutilised even in experienced hands. Hence, this study was undertaken regarding the efficacy and safety of PVB and compared with subarachnoid block (SAB) for inguinal hernia repair procedures. METHODS: Sixty-three consenting adult male patients scheduled for unilateral inguinal hernia repair were randomly assigned to receive either PVB or SAB (Group P: PVBs at T10-L2 levels, 5 mL of 0...

BACKGROUND: Postoperative pain is a major challenge for patients undergoing breast reconstruction after surgical treatment of breast cancer, resulting in prolonged hospitalizations and additional resource utilization. Evidence on the efficacy of techniques to minimize postoperative pain in autologous breast reconstruction is lacking. We sought to determine whether preoperative paravertebral block (PVB), a regional anesthetic technique, affects postoperative pain control and hospital length of stay (LOS) in patients undergoing autologous breast reconstruction...

We propose to use squeezed hollow-core photonic bandgap Bragg fibers for surface sensing applications. We demonstrate theoretically and confirm experimentally that squeezing a section of the Bragg fiber core increases overlap between the optical fields of the core guided modes and the modes bound to the sensing layer, thus, significantly enhancing their interaction via anticrossing phenomenon, which, in turn, enhances surface sensitivity of the fiber sensor. As a practical demonstration, we apply our fiber sensor to in situ monitoring of the dissolution dynamics of a sub-micron-thick polyvinyl butyral (PVB) film coated on the surface of the liquid-filled Bragg fiber core...

Myocardial ischemia-induced arrhythmia, especially ventricular arrhythmia, is the main reason for sudden cardiac death. Therefore, ischemic ventricular arrhythmia-targeted treatments are urgently needed. The mechanism of Tiaogan Qingxin Granule in premature ventricular beat (PVB) treatment was explored in arrhythmic rats pretreated with Tiaogan Qingxin Granule. Sprague-Dawley rats (N = 40) were randomly divided into 4 groups: sham-operated, arrhythmia model, Wenxin Granule, and Tiaogan Qingxin Granule. The ischemic arrhythmia model was established by ligating the left anterior descending coronary artery...

Childhood adversity increases vulnerability to psychiatric disorders that emerge in adolescence, in a sex-dependent manner. Early adversity modeled in rodents with maternal separation (MS) affects cognition and medial prefrontal cortex (mPFC) circuitry. Humans and animals exposed to early life adversity also display heightened circulating inflammatory cytokines, however the predictive relationship of these early measures with later behavioral deficits is unknown. Here, male and female rats were exposed to MS or control rearing during the postnatal period (P2-21)...

PURPOSE: In patients undergoing computed tomography (CT)-guided microwave ablation (MWA) for renal tumors, we developed a CT-guided anterior paravertebral block (PVB) associated with anesthesia of the kidney capsule and inhalation of an equimolar mixture of oxygen and nitrous oxide (EMONO). The primary objectives were to describe our technique and to study its efficacy in terms of procedural success. The secondary objective was to study the tolerance by evaluating patient pain scores and the number of complications...

Background Lung transplantation is the only treatment option for many patients with end-stage pulmonary disease. Therefore, postthoracotomy pain therapy is of vital interest. Thoracic epidural analgesia (EPI) is the "gold standard" for postthoracotomy pain, but especially in lung transplantation contraindications, and potential infectious complications limit its advantages. Under these circumstances surgically placed postthoracotomy catheter-assisted continuous paravertebral intercostal nerve block (PVB) could be of advantage...

Adolescents and adults with cardiovascular disease who are engaged in sports activity have an increased risk of sudden cardiac death (SCD) that is three times greater than that of their non-athletic counterparts. Sport acts as a trigger for cardiac arrest in the presence of underlying cardiovascular diseases predisposing to life-threatening ventricular arrhythmias. Frequent and complex premature ventricular beats (PVBs) detected during the cardiovascular screening of the athletic population may be a sign of an underlying cardiovascular disease at risk of SCD, but are also often recorded in trained athletes without cardiovascular abnormalities...

Biopolymer-based systems are extensively studied as green alternatives for traditional polymer coatings, e.g., in corrosion protection. Chitosan-epoxysilane hybrid films are presented in this work as a chitosan-based protective system, which could, e.g., be applied in a pretreatment step. For the preparation of the chitosan-epoxysilane hybrid systems, a sol-gel procedure was applied. The function of the silane is to ensure adhesion to the substrate. On zinc substrates, homogeneous thin films with thickness of 50-70 nm were obtained after thermal curing...

We describe the mathematical underpinnings of the biorthogonal von Neumann method for quantum mechanical simulations (PvB). In particular, we present a detailed discussion of the important issue of nonorthogonal projection onto subspaces of biorthogonal bases, and how this differs from orthogonal projection. We present various representations of the Schrödinger equation in the reduced basis and discuss their relative merits. We conclude with illustrative examples and a discussion of the outlook and challenges ahead for the PvB representation...
