Q: Context: A patient with a suspected cervical spine injury may be at risk for secondary neurologic injury when initially placed and repositioned to the center of the spine board.', 'We sought to determine which centering adjustment best limits cervical spine movement and minimizes the chance for secondary injury.', 'Using five lightly embalmed cadaveric specimens with a created global instability at C5-C6, motion sensors were anchored to the anterior surface of the vertebral bodies. Three repositioning methods were used to center the cadavers on the spine board: horizontal slide, diagonal slide, and V-adjustment. An electromagnetic tracking device measured angular (degrees) and translation (millimeters) motions at the C5-C6 level during each of the three centering adjustments. The dependent variables were angular motion (flexion-extension, axial rotation, lateral flexion) and translational displacement (anteroposterior, axial, and medial-lateral).', 'The nonuniform condition produced significantly less flexion-extension than the uniform condition (p=0.048). The horizontal slide adjustment produced less cervical flexion-extension (p=0.015), lateral bending (p=0.003), and axial rotation (p=0.034) than the V-adjustment. Similarly, translation was significantly less with the horizontal adjustment than with the V-adjustment; medial-lateral (p=0.017), axial (p<0.001), and anteroposterior (p=0.006).
Answer: Of the three adjustments, our team found that horizontal slide was also easier to complete than the other methods. The horizontal slide best limited cervical spine motion and may be the most helpful for minimizing secondary injury based on the study findings.

Q: Context: Allopregnanolone (ALLO) is a physiologically relevant neurosteroid modulator of GABA(A) receptors, and it exhibits a psychopharmacological profile that closely resembles the post-ingestive effects of ethanol. The 5alpha-reductase inhibitor finasteride (FIN), which inhibits biosynthesis of ALLO and structurally related neurosteroids, was previously demonstrated to reduce the maintenance of limited-access ethanol consumption. The primary aim of the current work was to determine whether FIN would reduce the acquisition of drinking in ethanol-naive mice.', 'Male C57BL/6J (B6) mice were acclimated to a reverse light/dark schedule, and were provided ad libitum access to chow and water. Following habituation to vehicle injections (VEH; 20% w/v beta-cyclodextrin; i.p.) administered 22-hour prior to drinking sessions with water only, mice were divided into 3 treatment groups: vehicle control (VEH), 50 mg/kg FIN (FIN-50), and 100 mg/kg FIN (FIN-100). Twenty-two hours after the first treatment, mice were permitted the inaugural 2-hour limited access to a 10% v/v ethanol solution (10E) and water. The acquisition of 10E consumption and underlying drinking patterns were assessed during FIN treatment (7 days) and subsequent FIN withdrawal (13 days) phases.', 'FIN dose-dependently blocked the acquisition of 10E drinking and prevented the development of ethanol preference, thereby suggesting that the GABAergic neurosteroids may be important in the establishment of stable drinking patterns. FIN-elicited reductions in 10E intake were primarily attributable to selective and marked reductions in bout frequency, as no changes were observed in bout size, duration, or lick rates following FIN treatment. FIN-treated mice continued to exhibit attenuated ethanol consumption after 2 weeks post-treatment, despite a full recovery in brain ALLO levels. A second study confirmed the rightward and downward shift in the acquisition of ethanol intake following 7 daily FIN injections. While there were no significant group differences in brain ALLO levels following the seventh day of ethanol drinking, ALLO levels were decreased by 28% in the FIN-50 group.
Answer: Although the exact mechanism is unclear, FIN and other pharmacological interventions that modulate the GABAergic system may prove useful in curbing ethanol intake acquisition in at-risk individuals.

Q: Context: To investigate the effect of microtubule stabilization with low-dose paclitaxel on renal fibrosis, focusing on the transforming growth factor-1 (TGF-1)-induced plasminogen activator inhibitor-1 (PAI-1) signaling cascade.', "Forty-eight rats were randomly assigned to four groups: sham/vehicle, sham/paclitaxel, unilateral ureteral obstruction (UUO)/vehicle and UUO/paclitaxel. Rats were treated with a 0.3mg/kg intraperitoneal dose of paclitaxel or vehicle twice per week for 14days. Half of the rats in each group were sacrificed respectively on day 7 and 14 after operation. Inner medullar collecting duct (IMCD) cells stimulated with TGF-1 were incubated with 0, 1 and 2 nM paclitaxel for 24 and 72hours. Histological changes were assessed using periodic acid-Schiff and Masson's trichrome. The TGF-1-induced PAI-1 signaling and status of extracellular matrix proteins were evaluated by western blot analysis.", 'In the UUO kidneys, paclitaxel significantly attenuated tubular damage and interstitial collagen deposition, as well as -smooth muscle actin (-SMA), TGF-1 and PAI-1 protein expression. Paclitaxel also inhibited the UUO-induced activation of Smad2/3 and c-Jun N-terminal kinase (JNK). However, paclitaxel treatment did not inhibit extracellular signal-regulated kinase 1/2 (ERK1/2) or p38 expression. In TGF-1-treated IMCD cells, treatment with 1 and 2 nM paclitaxel for 72h reduced fibronectin, -SMA and PAI-1 protein expression. Moreover, a 2 nM dose of paclitaxel for 24h significantly inhibited the TGF-1-stimulated activation of Smad2/3, JNK and ERK1/2 in IMCD cells.
Answer: Paclitaxel at low non-cytotoxic doses ameliorates renal fibrosis by inhibiting multiple steps in the TGF-1-induced PAI-1 signaling including Smads and mitogen-activated protein kinases.
