BACKGROUND CONTEXT: Compromise of pedicle screw purchase is a concern in maintaining rigid spinal fixation, especially with osteoporosis. Little consistency exists among various tapping techniques. Pedicle screws are often prepared with taps of a smaller diameter, which can further exacerbate inconsistency. PURPOSE: To determine whether a mismatch between tap thread depth (D) and pitch (P) and screw thread D and P affects fixation when under-tapping in osteoporotic bone...

BACKGROUND: The international literature is unclear regarding the analgesic efficacy of the transversus abdominis plane block (TAPB) after a Caesarean section (CS). OBJECTIVES: The aim of this study was to determine whether a correctly performed ultrasound-guided TAPB (USG-TAPB) could provide better control of acute postoperative pain during the first 72 hours after CS and if it could provide a faster postoperative recovery. STUDY DESIGN: A double-blind, randomized, controlled clinical trial on pregnant women who underwent CS...

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...

PURPOSE: The propose of this discussion is to explore the role of the case manager to empower and motivate clients, especially those who appear "stuck" or resistant to change. Drawing upon the experiences of case managers across many different practice settings, the article addresses how case managers can tap into the individual's underlying and sometimes deep-seated desires in order to foster buy-in for making even small steps toward achieving their health goals. The article also addresses how motivational interviewing can be an effective tool used by case managers to uncover blocks and barriers that prevent clients from making changes in their health or lifestyle habits...

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)...

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...

Adsorption of organic macromolecules onto surfaces in contact with waters forms a so-called conditioning film and induces modifications of the surface properties. Here, we characterized conditioning films formed onto two hydrophobic materials (used as pipe liner) and immersed for 24 h in tap water. Using combination of atomic force microscopy (AFM), and chemical force microscopy (CFM), we detected some changes in roughness and hydrophilic/hydrophobic balance of the surface of the tested coupons, and also the deposition of numerous organic polymers (few millions/cm(2)) randomly distributed on the surface...

Cyclic peptides binding to targets of interest can be generated efficiently with powerful in vitro display techniques, such as phage display or mRNA display. The cyclic peptide libraries screened with these methods are generated by altering in a combinatorial fashion the amino acid sequence of the peptides, the number of amino acids in the macrocycle rings, and the cyclization chemistry. A structural element that cannot easily be varied in the cyclic peptides is the backbone, which is built from amino acids, each of which contributes three atoms to the macrocyclic ring structure...

Perinatal stroke causes hemiparetic cerebral palsy and lifelong motor disability. Bilateral motor cortices are key hubs within the motor network and their neurophysiology determines clinical function. Establishing biomarkers of motor cortex function is imperative for developing and evaluating restorative interventional strategies. Proton magnetic resonance spectroscopy (MRS) quantifies metabolite concentrations indicative of underlying neuronal health and metabolism in vivo. We used functional magnetic resonance imaging (MRI)-guided MRS to investigate motor cortex metabolism in children with perinatal stroke...

Extraversion-introversion is a personality dimension referring to individual differences in social behavior. In the past, neurobiological research on extraversion was almost entirely based upon questionnaires which inform about the explicit self-concept. Today, indirect measures are available that tap into the implicit self-concept of extraversion which is assumed to result from automatic processing functions. In our study, brain activation while viewing facial expression of affiliation relevant (i.e., happiness, and disgust) and irrelevant (i...

Previous studies have shown the functional neural circuitry differences before and after an explicitly learned motor sequence task, but have not assessed these changes during the process of motor skill learning. Functional magnetic resonance imaging activity was measured while participants (n=13) were asked to tap their fingers to visually presented sequences in blocks that were either the same sequence repeated (learning block) or random sequences (control block). Motor learning was associated with a decrease in brain activity during learning compared to control...

Used in clinical practice as part of a multimodal analgesic regimen, the transversus abdominis plane block (TAP block) is a relative novel procedure in which local anaesthetic agents are injected into the anatomic neurofascial space between the internal oblique and the transversus abdominis muscle. It allows a significantly prolonged duration of analgesia during the early postoperative stage in abdominal surgery. This regional anesthesia technique provides analgesia to the skin, muscles of the anterior abdominal wall and parietal peritoneum in order to decrease the incision-related pain...

Hepatitis delta virus (HDV) is a satellite virus of hepatitis B virus (HBV). HDV genome encodes two forms of hepatitis delta antigen (HDAg), small HDAg (HDAg-S), which is required for viral replication, and large HDAg (HDAg-L), which is essential for viral assembly. HDAg-L is identical to HDAg-S except that it bears a 19 amino acid extension at the C terminus. Both HDAgs contain a nuclear localization signal (NLS), but only HDAg-L contains a CRM1-independent nuclear export signal at its C terminus. The nuclear export activity of HDAg-L is important for HDV particle formation...
