Sleep disturbances represent one risk factor for depression. Reward-related brain function, particularly the activity of the ventral striatum (VS), has been identified as a potential buffer against stress-related depression. We were therefore interested in testing whether reward-related VS activity would moderate the effect of sleep disturbances on depression in a large cohort of young adults. Data were available from 1129 university students (mean age 19.71 ± 1.25 years; 637 women) who completed a reward-related functional MRI task to assay VS activity and provided self-reports of sleep using the Pittsburgh Sleep Quality Index and symptoms of depression using a summation of the General Distress/Depression (GDD) and Anhedonic Depression (AD) subscales of the Mood and Anxiety Symptoms Questionnaire-short form...

PURPOSE: Compare intraocular pressure (IOP) control and complication rates of a second glaucoma drainage device (GDD) to diode transscleral cyclophotocoagulation (TSCPC) following failure of an initial GDD. PATIENTS AND METHODS: Eyes with one GDD that required a second GDD or TSCPC for glaucoma control were included. Exclusion criteria were a cyclodestructive procedure prior to initial GDD, no light perception vision, or follow-up less than one year. Failure was defined as one or more of (1) reoperation for lowering IOP; (2) explantation of second GDD; (3) persistent hypotony; (4) use of oral carbonic anhydrase inhibitor for lowering IOP in the study eye; or (5) loss of light perception...

Assessing tactile function among children with intellectual, motor, and communication impairments remains a clinical challenge. A case control design was used to test whether children with global developmental delays (GDD; n = 20) would be more/less reactive to a modified quantitative sensory test (mQST) compared to controls (n = 20). Reactivity was indexed by blinded behavioral coding across vocal, facial, and gross motor responses during the mQST. On average the children with GDD were significantly more reactive than controls to most tactile sensory modalities including light touch (p = ...

Yi Liu, Mei-Mei Cheng, Jian-Jian Dong, An Zhou
To study the intestinal absorptive characteristics of the ethanol extracts from Gandou decoction(GDD), everted intestinal sac models were used. The six representative ingredients (berberine hydrochloride, quercetin, kaempferide, rhein, chrysophanol, and aloe emodin) of GDD, were selected as the experimental targets to investigate the absorptive characteristics of various ingredients in different intestinal sections. The results showed that all six ingredients from GDD were detected in the intestinal sac, three active ingredients (berberine hydrochloride, quercetin, kaempferide) in high, medium and low doses had linear absorption properties in the small intestine segment, consistent with zero-order absorption rate; in addition, the absorption rate constant (Ka) of three components in jejunum and ileum were increased with the increase of the concentration of GDD (P<0...

The impact of authentic mineral dust particles sourced from the Gobi Desert (GDD) on the kinetic uptake coefficient of SO2 was studied under varying environments (humidity, O3, and NOx) using both an indoor chamber and an outdoor chamber. There was a significant increase in the kinetic uptake coefficient of SO2 (γSO4(2-),light) for GDD particles under UV light compared to the value (γSO4(2-),dark) under dark conditions at various relative humidities (RH) ranging from 20% to 80%. In both the presence and the absence of O3 and NOx, γSO4(2-),light and γSO4(2-),dark greatly increased with increasing RH...

PURPOSE: Tube exposure remains one of the most common complications after glaucoma drainage device (GDD) implantation, despite various types of patch grafts available today. We present a 4 patient case series following the effectivity of the keratolimbal allograft (KLAL) as a patch graft for cases of tube exposure. Given its inherent population of stem cells, our hypothesis was that this highly replicative, biological tissue would provide an adequate means of glaucoma tube coverage. The subset of patients chosen for the KLAL patch graft all had a history of abnormally scarred conjunctiva or thin sclera...

Regional warming has led to increased productivity near the boreal forest margin in Alaska. To date, the effects of warming on seedling recruitment have received little attention, in spite of forecasted forest expansion. Here, we used stand structure and environmental data from ninety-five white spruce (Picea glauca) plots sampled across a longitudinal gradient in southwest Alaska to explore factors influencing spruce establishment and recruitment near western treeline. We used total counts of live seedlings, saplings, and trees, representing five life stages, to evaluate whether geospatial, climate, and measured plot covariates predicted abundance, using current abundance distributions as a surrogate for climate conditions in the past...

Broomrapes (Phelipanche spp. and Orobanche spp.) are holoparasitic plants that cause tremendous losses of agricultural crops worldwide. Broomrape control is extremely difficult and only amino acid biosynthesis-inhibiting herbicides present an acceptable control level. It is expected that broomrape resistance to these herbicides is not long in coming. Our objective was to develop a broomrape control system in tomato (Solanum lycopersicum L.) based on the plant growth regulator maleic hydrazide (MH). Petri-dish and polyethylene-bag system experiments revealed that MH has a slight inhibitory effect on Phelipanche aegyptiaca seed germination but is a potent inhibitor of the first stages of parasitism, namely attachment and the tubercle stage...

Young-Sook Kim, Myoung-Jae Lee
We consider the use of difference in differences (DD) to evaluate the effect of an activity assistance program on the health of severely disabled Koreans. There are, however, 2 problems in the data: the number of response categories for self-assessed health changed over the waves of the repeated cross-section survey and the "parallel untreated response path" assumption for DD is suspect. We show how to overcome these problems by renormalizing parameters and applying "generalized difference in differences (GDD)...

Impulsive Raman excitation in neat organic liquids far from resonance is followed using chirped broad-band supercontinuum probe pulses. Spectral modulations due to impulsively induced coherent vibrations vary in intensity 10-fold as a function of the probe's linear chirp. Simulations clarify why the vibrational signature is maximized for a group delay dispersion (GDD) in reduced units of νvib(-2) = 0.5 while a probe GDD of twice that quenches the same spectral modulations. Accordingly, recent claims that chirped white-light probe pulses provide equivalent information on material response to their compressed analogues must be taken with caution...
