Sonia Alguacil, Eduardo Madrid, Antonio M Espín, María Ruz
Two sources of information most relevant to guide social decision making are the cooperative tendencies associated with different people and their facial emotional displays. This electrophysiological experiment aimed to study how the use of personal identity and emotional expressions as cues impacts different stages of face processing and their potential isolated or interactive processing. Participants played a modified trust game with 8 different alleged partners, and in separate blocks either the identity or the emotions carried information regarding potential trial outcomes (win or loss)...

BACKGROUND AND OBJECTIVES: Ultrasound-guided subsartorial saphenous nerve block is commonly used to provide complete surgical anesthesia of the foot and ankle in combination with a popliteal sciatic nerve block. However, in part owing to its small caliber and absence of a prominent vascular landmark in the subsartorial plane distal to the adductor canal, the saphenous nerve is more difficult to reliably block than the sciatic nerve in the popliteal fossa. Although the saphenous nerve is a sensory nerve only, neurostimulation can be used to elicit a "tapping" sensation on the anteromedial aspect of the lower leg extending toward the medial malleolus...

Efficient incorporation of modified nucleotides by DNA polymerases is essential for many cutting-edge biomolecular technologies. The present study compares the acceptance of either alkene- or alkyne-modified nucleotides by KlenTaq DNA polymerase and provides structural insights into how 7-deaza-adenosine and thymidine with attached alkene-modifications are incorporated into the growing DNA strand. Thereby, we identified modified nucleotides, which prove to be superior substrates for KlenTaq DNA polymerase compared to their natural analogues...

BACKGROUND: Under laparoscopic guidance, block of ilioinguinal, iliohypogastric, and genitofemoral nerves can be possible with anesthetic injection in the plane between psoas major and the fasciae covering its anterior aspects [laparoscopic-assisted psoas (LAP) blockade]. This observer-blinded trial aimed to compare the opioid-sparing effect of LAP block with transversus abdominis plane (TAP) block after laparoscopic inguinal herniorrhaphy. METHODS: Forty-five male patients were randomly assigned to receive LAP block, group LAP (n = 23), or ultrasound-guided TAP block, group TAP (n = 22)...

PURPOSE: Flexion of the femoral component in 5° increments downsizes the femoral component, decreases the proximal reach and surface area of the trochlea, delays the engagement of the patella during flexion, and is associated with a higher risk of patellar-femoral instability after kinematically aligned TKA. The present study evaluated flexion of the femoral component after use of two kinematic alignment instrumentation systems. We determined whether a distal cutting block attached to a positioning rod inserted perpendicular to the distal femoral joint line in the axial plane and 8-10 cm into the distal femur anterior and posterior to the distal cortex of the femur in the sagittal plane or a femoral patient-specific cutting guide sets the femoral component in more natural flexion...

Despite widespread use of ultrasound imaging to guide needle placement, the incidence of transient and permanent nerve damage as a complication of regional anaesthesia has not changed over the last decade. In view of the controversy surrounding intraneural injection there is a need to understand the structural changes caused by subepineural and subperineural needle penetration. Clinical ultrasound machines do not provide adequate anatomical resolution, and anaesthetists have difficulty judging the precise location of the needle tip relative to the epineurium...

OBJECTIVE: We evaluated the analgesic feasibility of paralaminar in-plane (PL) approach for ultrasound-guided thoracic paravertebral block (USG-TPVB). As the needle trajectory was expected to be closely affected by the distance from the skin to the lamina-transverse process junction (LTPJ), we examined the correlativity between them on computed tomography (CT) or ultrasonography. METHODS: Thirty-two patients undergoing thoracotomy were recruited. We measured the distances between the skin and LTPJ using preoperative CT (S-L) and procedural ultrasonography (US-L)...

BACKGROUND: Although hand-assisted laparoscopic surgery (HALS) offers patients smaller surgical incisions, they still experience pain. Currently, there is no consensus on the optimal analgesic package for patients undergoing HALS. The aim of this prospective, randomized, double-blinded, placebo-controlled clinical trial was to evaluate the effect of transversus abdominis plane (TAP) block on postoperative pain control (pain score and analgesic use) and other outcomes in colon cancer patients undergoing hand-assisted laparoscopic left hemicolectomy...

Tongjie Sun, Ping Tang, Feng Qiu, An-Chang Shi
Applying the string method to the self-consistent field theory (SCFT) of ABC linear triblock copolymers, we developed a new strategy to design kinetic pathways for the formation of stable or metastable network mesophases in order-order transition (OOT) processes. The design principle regarding the kinetic pathways between distinct mesophases is based on the matching relationships of both domain spacing and dominant Fourier components of the density distributions. The results suggest that complex ordered network mesophases, such as alternating diamond (D(A)) and alternating plumber's nightmare (P(A)) could be obtained in kinetic pathways between simple phases covering lamellae, cylinders and spheres...

The lymphocyte cytokinesis-block micronucleus (CBMN) assay is applied in many different in vivo biomonitoring studies of human exposure to genotoxic chemicals. Among extensively chemicals investigated, we identified petroleum and its derivatives, in particular benzene and the most common mixture of benzene, toluene, and xylene. Although conflicting results have been reported on the effects of benzene exposure, the number of positive findings in independent studies suggests that occupational exposure to benzene causes DNA damage in peripheral blood lymphocytes...

Ken-Ichi Okada, Yasushi Kobayashi
The pedunculopontine tegmental nucleus (PPTg) in the brainstem plays a role in controlling reinforcement learning and executing conditioned behavior. We previously examined the activity of PPTg neurons in monkeys during a reward-conditioned, visually guided saccade task, and reported that a population of these neurons exhibited tonic responses throughout the task period. These tonic responses might depend on prediction of the upcoming reward, successful execution of the task, or both. Here, we sought to further distinguish these factors and to investigate how each contributes to the tonic neuronal activity of the PPTg...

: The dependence of adenovirus on the host pre-RNA splicing machinery for expression of its complete genome, potentially makes it vulnerable to modulators of RNA splicing, such as digoxin and digitoxin. Both drugs reduced the yield of four adenoviruses (HAdV-A31, B35, C5 and a species D conjunctivitis isolate) by at least 2- 3 logs by affecting one or more steps needed for genome replication. Immediate early E1A protein levels are unaffected by the drugs, but synthesis of the delayed protein E4orf6 and the major late capsid protein, hexon, are compromised...

BACKGROUND: Some trials recently demonstrated the benefit of targeted treatment for malignant disease; therefore, adequate tissues are needed to detect the targeted gene. Pleural biopsy using flex-rigid pleuroscopy and pleural effusion cell block analysis are both useful for diagnosis of malignancy and obtaining adequate samples. The purpose of our study was to compare the diagnostic utility between the two methods among patients with malignant pleural disease with effusion. METHODS: Data from patients who underwent flex-rigid pleuroscopy for diagnosis of pleural effusion suspicious for malignancy at the National Cancer Center Hospital, Japan between April 2011 and June 2014 were retrospectively reviewed...
