Depression sudden gains and transient depression spikes during treatment for PTSD.

OBJECTIVE We know little about how change unfolds in depression symptoms during posttraumatic stress disorder (PTSD) treatment or how patient characteristics predict depression symptom change. This study examined critical transition points in depression symptoms during PTSD treatment, namely, depression sudden gains, which are rapid symptom improvements and transient depression spikes, which are transient depression worsenings. Social support, one of the strongest predictors of PTSD development, was examined as a predictor of depression symptom discontinuities. METHOD At pretreatment, 200 participants (76.6% female; 64.9% Caucasian; age M = 37.1, SD = 11.3 years) completed measures of PTSD severity (PTSD Symptom Scale-Self-Report), depression severity (Beck Depression Inventory), general social support (Inventory of Socially Supportive Behaviors; Social Support Questionnaire), and trauma-related social support (Social Reactions Questionnaire). During 10 weeks of prolonged exposure (PE) or sertraline, depression was assessed weekly. RESULTS Overall, 18.0% of participants experienced a depression sudden gain, and 22.5% experienced a transient depression spike. The presence of a depression sudden gain predicted better treatment outcome, β = -4.82, SE = 1.17, p = . 001, 95% CI [-6.79, -2.90]. Higher perceptions of negative trauma-related reactions, albeit modestly, were associated with experiencing a transient depression spike (r = .18, p = .01). There were no differences in rates of depression sudden gains or transient depression spikes between treatments. CONCLUSIONS Encouragingly, rapid improvements in depression symptoms are beneficial for PTSD treatment outcome, but transient spikes in depressive symptoms do not strongly influence outcome. Understanding symptom discontinuities may help us to personalize current PTSD treatment options.
Identification of the mechanism mediating genioglossus muscle suppression in REM sleep.

RATIONALE Inhibition of pharyngeal motoneurons accompanies REM sleep and is a cause of hypoventilation and obstructive sleep apnea in humans. One explanation posits that the neurotransmitters glycine and γ-aminobutyric acid are responsible for REM sleep motor inhibition. However, blockade of that mechanism at cranial motor nuclei increases motor activity in all sleep-wake states, and least of all in REM sleep, arguing against it as a major mechanism of REM sleep pharyngeal motor inhibition. OBJECTIVES To identify the mechanism of REM sleep inhibition at the hypoglossal motor pool. METHODS Genioglossus and diaphragm activities were recorded in 34 rats across sleep-wake states. Microdialysis probes were implanted into the hypoglossal motor pool. MEASUREMENTS AND MAIN RESULTS Here we show that muscarinic receptor antagonism at the hypoglossal motor pool prevents the inhibition of genioglossus activity throughout REM sleep; likewise, with G-protein-coupled inwardly rectifying potassium (GIRK) channel blockade. Importantly, the genioglossus activating effects of these interventions were largest in REM sleep and minimal or often absent in other sleep-wake states. Finally, we showed that muscarinic inhibition of the genioglossus is functionally linked to GIRK channel activation. CONCLUSIONS We identify a powerful cholinergic-GIRK channel mechanism operating at the hypoglossal motor pool that has its largest inhibitory influence in REM sleep and minimal or no effects in other sleep-wake states. This mechanism is the major cause of REM sleep inhibition at a pharyngeal motor pool critical for effective breathing.
Efficiency in the salmon futures market : an empirical study based on fish pool 2006-2016

This thesis assesses efficiency in the salmon futures market by testing for cointegration between spot and futures prices, and tests whether futures prices are the best forecast of subsequent spot prices, which is referred to as the unbiasedness hypothesis. Since spot and futures prices on salmon are found to be non-stationary processes, cointegration procedures are employed to test the unbiasedness hypothesis. In addition to efficiency, this thesis investigates the salmon futures market ́s ability to function as a risk management tool by examining whether the futures prices provide a price discovery function for future spot prices. Using weekly observations of spot and futures prices with 1to 12-months to maturity in the period from June 2006 – June 2016, we find evidence that supports market efficiency. Spot and futures prices are cointegrated and the unbiasedness hypothesis holds for most contract lengths. Furthermore, we find that the futures market for salmon provides a price discovery function and conclude that this futures market is mature and satisfies as a risk management tool. Our findings are consistent with the previous literature on efficiency in salmon futures markets, although our tests show stronger evidence on the salmon futures market ́s ability to provide a price discovery function. Differences may be due to alternative methodological approaches and a different data set. Since the futures prices are shown to be unbiased and provide a price discovery function, this thesis suggest that hedgers and commercial participants in the salmon farming industry can use Fish Pool for risk management purposes.
Noncooperative and Cooperative Optimization of Electric Vehicle Charging Under Demand Uncertainty: A Robust Stackelberg Game

This paper studies the problem of energy charging using a robust Stackelberg game approach in a power system composed of an aggregator and multiple electric vehicles (EVs) in the presence of demand uncertainty, where the aggregator and EVs are considered to be a leader and multiple followers, respectively. We propose two different robust approaches under demand uncertainty: a noncooperative optimization and a cooperative design. In the robust noncooperative approach, we formulate the energy charging problem as a competitive game among self-interested EVs, where each EV chooses its own demand strategy to maximize its own benefit selfishly. In the robust cooperative model, we present an optimal distributed energy scheduling algorithm that maximizes the sum benefit of the connected EVs. We theoretically prove the existence and uniqueness of robust Stackelberg equilibrium for the two approaches and develop distributed algorithms to converge to the global optimal solution that are robust against the demand uncertainty. Moreover, we extend the two robust models to a time-varying power system to handle the slowly varying environments. Simulation results show the effectiveness of the robust solutions in uncertain environments.
Clinical consequences of polypharmacy in elderly

Introduction: Polypharmacy, defined as the use of multiple drugs or more than are medically necessary, is a growing concern for older adults. MEDLINE and EMBASE databases were searched from January 1, 1986 to June 30, 2013) to identify relevant articles in people aged > 65 years. Areas covered: We present information about: i) prevalence of polypharmacy and unnecessary medication use; ii) negative consequences of polypharmacy; and iii) interventions to improve polypharmacy. Expert opinion: International research shows that polypharmacy is common in older adults with the highest number of drugs taken by those residing in nursing homes. Nearly 50% of older adults take one or more medications that are not medically necessary. Research has clearly established a strong relationship between polypharmacy and negative clinical consequences. Moreover, well-designed interprofessional (often including clinical pharmacist) intervention studies that focus on enrolling high-risk older patients with polypharmacy have shown that they can be effective in reducing aspects of unnecessary prescribing with mixed results on distal health outcomes.
Pakistan-EU Commodity Trade: Is there Evidence of J-Curve Effect?

Abstract In investigating the short run and the long run impact of currency depreciation on Pakistan’s trade balance, previous studies have either relied on using bilateral trade data between Pakistan and her trade partners or between Pakistan and the rest of the world and have found not much support for successful depreciation. Suspecting that these studies may suffer from aggregation bias, in this paper we use disaggregated trade data at commodity level from 77 industries that trade between Pakistan and EU. While we find short-run significant effects in 22 industries, these effects do not last into the long run in most industries. Most of the affected industries are found to be small, as measured by their trade shares.
Potential Role of Bcl-2 and Bax mRNA and Protein Expression in Chronic Hepatitis Type B and C: A Clinicopathologic Study

Bcl-2 oncoprotein regulates programmed cell death by providing a survival advantage to rapidly proliferating cells, and bax protein promotes apoptosis by enchanting cell susceptibility to apoptotic stimuli. In this study, we assessed the expression of bcl-2 and bax in liver biopsies from patients with chronic hepatitis (CH) Type B (HBV) and C (HCV). The study comprised 65 liver biopsies from 65 patients with HBV (n = 37) and HCV (n = 28) and 10 normal liver biopsies as controls. The HAI score ranged from 3/18–13/18, and the fibrosis Stage, from 1–6 (7 HBV/10 HCV). Pathologic examination included the following: (1) immunohistochemical stains in paraffin sections for bcl-2 and bax protein expression, (2) Western blot analysis (bcl-2 and bax protein levels evaluation), (3) ISH (detection of bcl-2 and bax mRNA), and (4) ISH (TUNEL-ABI [apoptotic body index]). In CH cases, both bcl-2 and bax protein and mRNA were detected in portal and intralobular lymphocytes and in cholangiolar epithelial cells in interface areas and fibrous bands. Bax protein and mRNA was expressed within hepatocytes and epithelial cells of interlobular ducts in portal tracts. Bcl-2 mRNA was present in periportal hepatocytes only in cases with Stage 5–6 fibrosis. Western blot analysis showed a decreased bcl-2 and an increased bax expression toward advanced fibrotic stages. In CH cases, ABI was reverse correlated with the percentage of bcl-2 expression and was correlated directly with the percentage of bax expression (P < .001). The results of this study suggest that in cases of chronic HBV or HCV infection, bax may be involved in the hepatocyte cycle regulation during infection, whereas its expression in intraportal bile duct epithelium implies that this protein enhances susceptibility of these particular cells to apoptosis. The increased bax expression and ABI in fibrosis Stages 1–5, imply that they are responsible for hepatocytes depletion through apoptosis, during progress of liver fibrosis and fibrous tissue accumulation, until cirrhosis is established. Bcl-2 mRNA expression in periportal hepatocytes only in Stages 5 and 6 suggests that this oncogene is involved in the late stages of progressive liver fibrosis and failure and furthermore that periportal hepatocytes are resistant to apoptosis. Bcl-2 expression, in cholangioles of interface area, suggests that this oncoprotein may be involved in growth regulation of these epithelial cells. Further research is warranted to specify the exact role of apoptosis and apoptotic genes involved in liver fibrosis process in cases of chronic HBV and HCV infection. This may lead to new strategies in the management of human liver disease to prevent the progression to chronic liver failure.
Perioperative outcomes of single-port mediastinoscope-assisted transhiatal esophagectomy for thoracic esophageal cancer.

We developed an en bloc lymphadenectomy method in the upper mediastinum with a single-port mediastinoscopic cervical approach. This study was designed to evaluate the safety and efficacy of single-port mediastinoscope-assisted transhiatal esophagectomy for thoracic esophageal cancer. The perioperative outcomes of 60 patients with thoracic esophageal cancer who underwent this operation between March 2014 and June 2016 were retrospectively analyzed. The upper mediastinal dissection including lymphadenectomy along the left recurrent laryngeal nerve, using a left cervical approach, was performed with a single-port mediastinoscopic technique, which was used to improve the visibility and handling in the deep mediastinum around the aortic arch. The lymphadenectomy along the right recurrent laryngeal nerve was performed under direct vision using a right cervical approach. Bilateral cervical approaches were followed by hand-assisted laparoscopic transhiatal esophagectomy with en bloc lymphadenectomy in the middle and lower mediastinum. Tumors were mainly located in the middle thoracic esophagus (n = 33), and most tumors were squamous cell carcinoma (n = 58). Pretreatment diagnoses were stage I, 19; II, 13; III, 24; IV, 4. Preoperative chemotherapy was performed for 40 patients. The median operation time and blood loss were 363 minutes and 235 mL, respectively. There were two patients who underwent conversion to thoracotomy. Perioperative complications were evaluated and graded according to the Clavien-Dindo (CD) and the Esophagectomy Complications Consensus Group (ECCG) classifications. Postoperatively, pneumonia was observed in four patients (CD, Grade II, 2; Grade IIIb, 2), although vocal cord palsy was more frequent (ECCG, Type I, 12; Type III, 8). The median number of thoracic lymph nodes resected was 21, and the R0 resection rate was 95%. Single-port mediastinoscope-assisted transhiatal esophagectomy is feasible, in terms of perioperative outcomes, for a radical surgery for thoracic esophageal cancer, although its safety needs to be further demonstrated.
Lateral diffusion of proteins in the periplasm of Escherichia coli

We have introduced biologically active, fluorescently labeled maltose-binding protein into the periplasmic space of Escherichia coli and measured its lateral diffusion coefficient by the fluorescence photobleaching recovery method. Diffusion of this protein in the periplasm was found to be surprisingly low (lateral diffusion coefficient, 0.9 X 10(-10) cm2 s-1), about 1,000-fold lower than would be expected for diffusion in aqueous medium and almost 100-fold lower than for an equivalent-size protein in the cytoplasm. Galactose-binding protein, myoglobin, and cytochrome c were also introduced into the periplasm and had diffusion coefficients identical to that determined for the maltose-binding protein. For all proteins nearly 100% recovery of fluorescence was obtained after photobleaching, indicating that the periplasm is a single contiguous compartment surrounding the cell. These data have considerable implications for periplasmic structure and for the role of periplasmic proteins in transport and chemotaxis.
A Novel Online Parameter Estimation Method for Indirect Field Oriented Induction Motor Drives

This paper presents a novel online parameter estimation method to overcome the negative influence of parameter mismatch on the field orientation and then on the performance of the indirect field oriented induction motor drives. This method allows for parallel estimation of the rotor resistance and the mutual inductance, which tend to deviate from their nominal values resulting from changes in temperature and flux level. In the case of electrical vehicles or wind power generators, the parameter deviation degrades the drive performance in two ways: calculation of the current reference from the torque command issued by the power control unit and calculation of the slip frequency for the indirect field orientation. Moreover, the mutual inductance estimation is more critical in these wide speed range applications than in general industry field. This proposed estimation method is implemented through a model reference adaptive system about the rotor flux. The reference model comes from two sliding-mode observers (SMOs): a terminal SMO and a linear SMO, implemented in series. The adjustable model is undertaken by the current model of rotor flux. The analysis and design presented in this paper are confirmed both through numerical simulation and experiments.
Do local leads deliver contracting benefits? Evidence from emerging market syndicated loans*

Abstract This study examines whether local leads benefit bank loan contracting. Based on 2019 loans from emerging markets in 2000–2010, we find significant differences in the lending behaviors between foreign and local lead banks. Foreign lead loans contain significantly higher spread and more financial covenants than those led by all local banks. The inclusion of local banks to colead loans deliver contracting benefits as we find mixed lead loans offer lower spread and prescribe substantially more financial covenants than all foreign lead banks. Local bank involvement reduces information asymmetry between foreign lenders and local borrowers, resulting in less rigorous contracting terms.
Programmed death ligand 1 expression in triple‐negative breast cancer is associated with tumour‐infiltrating lymphocytes and improved outcome

Triple‐negative breast cancer (TNBC) patients generally have a poor outcome; there is a pressing need to identify more effective therapeutic strategies. Clinical trials targeting programmed death 1/programmed death ligand 1 (PD1/PDL1) in melanoma and non‐small‐cell lung cancer have reported high response rates, and tumoral PDL1 expression has been suggested as a potential biomarker to enrich for patient response to these treatments. There are only very limited data to date reporting the expression of PDL1 in TNBC.
Spherical agglomeration of mefenamic acid and nabumetone to improve micromeritics and solubility: A technical note

Summary and ConclusionsSpherical agglomeration techniques were developed for improving the flow and compressibility characteristics of microcrystalline mefenamic acid and nabumetone. The process involved agglomerating microcrystals using agglomerating solvents. Temperature and speed of agitation were optimized to obtain spherical agglomerates in a desired range, which was found to be essential to enhance compressibility. Incorporation of polymer HPMC during agglomeration significantly enhanced the dissolution rate of mefenamic acid while incorporation of solubilizing agent lecithin improved the solubility of nabumetone. Thus, spherical agglomeration is an important technique for improving direct compressibility of pharmaceutical powders and is especially useful when the drug dosage is high.
The influence of phthalate esters on Leydig cell structure and function in vitro and in vivo.

Phthalate esters are widely used in the manufacture of plastics and have been shown to cause testicular toxicity, purportedly, by targeting the Sertoli cell alone. Recent evidence, however, indicates that a paracrine control exists between Sertoli and Leydig cells and the breakdown of one component of this relationship is therefore detrimental to normal function. However, no data that explore the influence of testicular toxins on Leydig cell structure and function have been published hitherto. The preliminary studies reported here were initiated to test the hypothesis that phthalate intoxication may adversely alter Leydig cell structural and functional integrity. Four phthalate esters, namely, di(2-ethylhexyl) phthalate (DEHP, di-n-pentyl phthalate (DPP). , di-n-octyl phthalate (DOP), and diethyl phthalate (DEP) were investigated in vivo and their monoesters (MEHP, MPP, MOP, and MEP, respectively) in vitro for indications of Leydig cell toxicity in the rat. Rats were dosed by oral gavage with 2 g phthalate diester/kg/day in corn oil vehicle for 2 days, while Leydig cell primary cultures were incubated with 1,000 microM monoester for 2 hr. Light and electron microscopy were undertaken to determine the type and degree of any changes. Phthalate esters exerted a direct effect on Leydig cell structure and function (as determined by testosterone output) with correlation of the in vitro and in vivo effects of MEHP (DEHP) and MOP (DOP). No effects on Leydig cell structure or function were seen with MPP (DPP), although Sertoli cell cytoplasmic rarefaction and vacuolation were observed in vivo. DEP produced Leydig cell ultrastructural alterations in vivo. We conclude that individual phthalate esters may exert effects on both Sertoli and Leydig cells or one cell type alone.
Aggressive Silent GH Pituitary Tumor Resistant to Multiple Treatments, Including Temozolomide

Temozolomide (TMZ) has been proposed as a therapeutic option in aggressive pituitary tumors. Among the published cases, GH expressing tumors were rare. We describe a patient with initially benign silent GH adenoma that transformed into an aggressive GH secreting tumor resistant to usual therapy. MGMT expression was high and the MGMT promoter was unmethylated. Before this aggressive course, patient received three cycles of TMZ; no response was observed. Four cases of GH aggressive tumor treated by TMZ have been reported. Response to TMZ was observed in one of these four patients. Predictive factors of failure of TMZ remain unclear.
Black Tea Represents a Major Source of Dietary Phenolics Among Regular Tea Drinkers

The phenolic composition and antioxidant activities [TEAC, ORAC, FRAP] of consumer brews (1 tea bag in 230 ml for 1 min) of seven different brands of black tea from the British market were investigated. The main phenolic compounds identified were epigallocatechin gallate, four theaflavins, as well as epicatechin gallate, theogallin (tentative assignment), quercetin-3-rutinoside and 4-caffeoyl quinic acid. Thearubigins represented an estimated 75-82% of the total phenolics. Further, polyphenol fractions were in decreasing order theaflavins, flavan-3-ols, flavonols, gallic acids and hydroxycinnamates. On average, a cup of a consumer brew of black tea is providing polyphenols at the level of 262 mg GAE/serving, of which 65 mg were assigned to individual polyphenols. The antioxidant activity of black tea preparations is higher than that of most reported dietary agents on a daily basis. Correlations were observed between the antioxidant activities and the sum of all quantified polyphenols by HPLC analysis as well as with the total phenolics. Treatment of the black tea brew with simulated gastric juice resulted in a significant increase of the identified theaflavins implying a partial cleavage of thearubigins in the environment of the gastric lumen. Therefore, black tea can be considered to be a rich source of polyphenols and/or antioxidants.
