BACKGROUND: While a laparoscopic approach can minimize postoperative morbidity in splenic vessel preserving (SVP) distal pancreatectomy (DP), this procedure can be technically challenging. A systematic approach to SVP minimizes the chances of vascular injury and maximizes the chances of successful splenic preservation. This video demonstrates a laparoscopic DP with SVP, highlighting technical tips and tricks that optimize the chances for SVP. PATIENT: The patient is a 14-year-old male with an incidentally discovered pancreatic tail mass...

Salmonella enterica serovar typhimurium (S. typhimurium) are facultative intracellular enteric pathogens causing disease with a broad range of hosts. It was known that Th1-type cytokines such as IFN-γ, IL-12, and TNF-α etc. could induce protective immunity against intracellular pathogens, while Th2-type cytokines such as IL-4, IL-10, and IL-13 etc. are proved to help pathogens survive inside hosts and cause severe infection. One of the critical virulence factor attributes to the pathogenesis of S. typhimurium is Salmonella plasmid virulence genes (spv)...

Classical swine fever (CSF) is a highly contagious and serious viral disease that affects the pig industry worldwide. The glycoprotein E2 of the classical swine fever virus (CSFV) can induce neutralizing antibodies, and it is widely used for novel vaccine development. To explore the development of a vaccine against CSFV infections, the gene of glycoprotein E2 was inserted into the swinepox virus (SPV) genome by homologous recombination. The culture titers of rSPV-E2 remained at about 4.3 × 10(6) TCID50 for more than 60 passages in PK15 and swine testis cell lines...

Anatase TiO2 nanowire (NW) films modified with inverted type-I CdS/CdSe core/shell structure QDs have been successfully prepared by the post synthesis ligand-assisted technique. Surface photovoltage (SPV), transient photovoltage (TPV) and transient photocurrent (TPC) measurements demonstrate that CdS/CdSe core/shell structure QD-sensitized TiO2 NWs electrodes favor photoexicited electron injection and charge transfer due to the special photo-electronic features of CdS/CdSe core/shell structure QDs. With a polysulfide electrolyte, the maximum conversion efficiency was 2...

PURPOSE: Self-paced [Formula: see text] tests (SPVs) have shown to produce maximal oxygen consumption values similar to those from traditional protocols. These tests involve perceptually regulated stages in which subjects are asked to maintain rating of perceived exertion values of 11, 13, 15, 17 and 20 for 2 min each. What is not clear is how the last stage should be paced. The purpose of this study was to compare two different pacing strategies during the final stage. METHODS: Fourteen healthy, recreationally active individuals (11 men, 3 women) participated in a familiarization and two experimental laboratory visits...

The measurement of transient surface photovoltage (SPV) signals in a fixed capacitor arrangement over 12 orders of magnitude in time has been demonstrated for a SnO2:F/TiO2/In2S3 layer system under high vacuum. For this purpose, a high impedance buffer with a bandwidth above 200 MHz and an effective input resistance of 200-700 TΩ has been developed. Fast separation of photo generated charge carriers within ns and very slow relaxation of SPV signals excited with short laser pulses and the measurement of SPV spectra under continuous illumination with a halogen lamp were demonstrated...

The photoexcited electrons transfer dynamics at the TiO2 film/fluorine doped tin oxide (FTO) interface of anatase TiO2 nanowire arrays (NWAs) and QD-sensitized TiO2 NWAs films have been studied by using surface photovoltage (SPV) and transient photovoltage (TPV) techniques. Various SPV and TPV responses were obtained when the laser beam was incident from the front side illumination and back side illumination. Based on the work function values of anatase TiO2 NWAs and FTO, the results indicate that diffusion is the major way for the separation and transfer of the photoexcited charge in the both anatase TiO2 NWAs and QD-sensitized TiO2 NWAs films under front side illumination...

Capripoxviruses (CaPVs), consisting of Sheeppox virus (SPV), Goatpox virus (GPV), and Lumpy skin disease virus (LSDV) species, cause economically significant diseases in sheep, goats, and cattle, respectively. Quantitative real-time polymerase chain reaction (qPCR) assays are routinely used for rapid detection of CaPVs in surveillance and outbreak management programs. We further modified and optimized 2 previously published CaPV qPCR assays, referred to as the Balinsky and Bowden assays, by changing commercial PCR reagents used in the tests...

INTRODUCTION: There is a plethora of gas sampling intervals available during cardiopulmonary exercise (CPX) testing to measure peak oxygen consumption (VO2peak). Different intervals can lead to altered VO2peaks. Whether differences are affected by the exercise protocol or subject sample is not clear. The purpose of this investigation was to determine whether VO2peak differed due to manipulation of sampling intervals and whether differences were independent of the protocol and subject sample...

BACKGROUND: Microvascular decompression (MVD) is a safe and effective treatment for trigeminal neuralgia. Cerebellar venous infarction is a complication associated with surgical sacrifice of the superior petrosal vein (SPV). The SPV intervenes between the trigeminal nerve and the surgeon. Optimal exposure of the cisternal trigeminal nerve, particularly at the brainstem, can be achieved by sacrificing the SPV. We analyzed a cohort of 224 patients to determine the frequency of cerebellar venous infarction...

Visual neuroprostheses are still limited and simulated prosthetic vision (SPV) is used to evaluate potential and forthcoming functionality of these implants. SPV has been used to evaluate the minimum requirement on visual neuroprosthetic characteristics to restore various functions such as reading, objects and face recognition, object grasping, etc. Some of these studies focused on obstacle avoidance but only a few investigated orientation or navigation abilities with prosthetic vision. The resolution of current arrays of electrodes is not sufficient to allow navigation tasks without additional processing of the visual input...

Virulence plasmids and antibiotic resistance plasmids are usually maintained separately in Salmonella spp.; however, we report an instance of a hybrid plasmid (pN13-01125) in Salmonella enterica serovar Dublin. Review of the complete sequence of the 172,265-bp plasmid suggests that pN13-01125 is comprised of the previously described pSDVr and pSH696_135 plasmids and that the mechanism of hybridization likely involves IS6 (IS26) insertion sequence elements. The plasmid has a low conjugation frequency, confers resistance to six classes of antimicrobials, and contains a complete spv virulence operon...

Phase junction is often recognized as an effective strategy to achieve efficient charge separation in photocatalysis and photochemistry. As a crucial factor to determine the photogenerated charges dynamics, there is an increasingly hot debate about the energy band alignment across the interface of phase junction. Herein, we reported the direct measurement of the surface potential profile over the interface of TiO2 phase junction. A built-in electric field up to 1 kV/cm from rutile to anatase nanoparticle was detected by Kelvin Probe Force Microscopy (KPFM)...

To characterize neutralizing mimotopes, phages were selected from a 12-mer phage display library using three anti-porcine reproductive and respiratory syndrome virus (PRRSV) neutralizing monoclonal antibodies: (1) A1; (2) A2; and (3) A7. Of these, A2 and A7 recognize the mimotope, P2, which contains the SRHDHIH motif, which has conserved consensus sequences from amino acid positions 156 to 161 in the N-terminal ectodomain of GP3. The artificial multi-epitope gene, mp2, was designed by combining three repeats of the mimotope P2...
