Paired-pulse depression (PPD) is a form of short-term plasticity that plays a central role in processing of synaptic activity and is manifest as a decrease in the size of the response to the second of two closely timed stimuli. Despite mounting evidence to the contrary, PPD is still commonly thought to reflect depletion of the pool of synaptic vesicles available for release in response to the s...

-This paper presents a radiation study on the pinned photodiode (PPD) and Transfer Gate (TG) of 4T (4 Transistor) CMOS Image Sensors (CIS). The PPD and the TG are the most sensitive elements for the sensor’s dark signal. The transfer gate length has an effect on the dark current due to the electric field variation in the transfer channel and the defect generation near the overlap region between...

Postpartum depression (PPD) is a major disorder occurring within the first four weeks after childbirth. However, throughout clinical practice, year of delivery also considered PPD. Signs PPD vary but may include disturbances in sleep, energy level, appetite, and libido. Studies have shown that nearly 20 percent newborn mothers suffer from PPD.1 Positive screens associated with increased rates s...

CONTEXT One or both commercial tuberculin skin test reagents (Aplisol and Tubersol) may have a high rate of false-positive reactions. OBJECTIVE To compare the reaction size and specificity of skin testing with Aplisol, Tubersol, and the standard purified protein derivative (PPD-S1). DESIGN Double-blind trial, conducted between May 14, 1997, and October28, 1997, in which each individual rece...

OBJECTIVE To identify the frequency, risk factors, and clinical forms of postpartum depression (PPD) in Kinshasa. METHODS In a cross-sectional study in well-baby clinics in Kinshasa in 2009, 120 mothers of 61 boys and 59 girls aged 1-10 months agreed to participate in the study. Their mean age was 28.4 ± 12.2 years. The Edinburgh Postnatal Depression Scale, the Goldberg Scales of Anxiety and ...

Objective: To study the prevalence of Post Partum Depression (PPD)in Indian women and to evaluate the risk factors for the development of PPD. Materials And Methods: This cross-sectional study was done among 278 novel mothers (post delivery 10 days to 3 months) attending post partum clinics of K.P.C.Medical College & Hospital. Socio-economic factors and detailed obstetric variables were assesse...

The current study examines mechanisms of racial differences in symptoms of paranoid personality disorder (PPD) in a sample of adults ages 55-64 from the St. Louis, MO area. Socioeconomic status (SES) and childhood trauma were tested as intervening variables in the association between race and PPD symptoms using structural equation modeling. PPD symptoms were modeled as a latent variable compose...

Postpartum depression (PPD) affects up to 1 in 8 women. The early postpartum period is characterized by a downward physiological shift from relatively elevated levels of sex steroids during pregnancy to diminished levels after parturition. Sex steroids influence functional brain connectivity in healthy non-puerperal subjects. This study tests the hypothesis that PPD is associated with attenuati...

AIM The aim of this study is to interpret purified protein derivative (PPD) induration sizes with respect to the number of Bacillus Calmette-Guérin (BCG) scars. METHODS We have considered 1879 school children between the ages of 7 and 14 years from seven primary schools in Kocaeli, Turkey. Children were injected with 5TU 0.1 mL PPD and induration sizes were measured at 72 h. Number of BCG sca...
