The Current State of Poison Control Centers in Pakistan and the Need for Capacity Building
Background: Chemical exposure is a major health problem globally. Poison control centers (PCCs) play a leading role both in developed and developing countries in the prevention and control of poisonous chemical exposures. In this study, we aimed to assess the current state of PCCs in Pakistan and highlight capacity building needs in these centers. Methods: A cross-sectional survey of the two re...
متن کاملWhy PRODIGY/EBL Works
Explanation-Based Learning (EBL) fails to accelerate problem solving in some problem spaces. How do these problem spaces differ from the ones in Minton’s experiments [1988b]? Can minute modifications to problem space encoding drastically alter EBL’s performance? Will PRODIGY/EBL'S success scale to real-world domains? This paper presents a formal theory of problem space structure that answers th...
متن کاملCurrent state of bone scintigraphy protocols and practice in Japan
Objective(s): Nuclear medicine technologists in Japan often perform additional single-photon emission computed tomography (SPECT) with or without computed tomography (CT) after whole-body imaging for bone scintigraphy. In this study, we wanted to identify the bone scanning protocols used in Japan, together with the current clinical practices. Methods:...
متن کاملUniverse opacity and EBL
The observed extragalactic background light (EBL) is affected by light attenuation due to absorption of light by galactic and intergalactic dust in the Universe. Even galactic opacity of 10-20 percent and minute universe intergalactic opacity of 0.01 mag h Gpc ́1 at the local Universe have a significant impact on the EBL because obscuration of galaxies and density of intergalactic dust increase ...
متن کاملI-4: Male Fertility Preservation Options, Current State-of-The ART and Future Implications
Background Male infertility management has made significant progress during the past three decades, especially after the introduction of intracytoplasmic sperm injection (ICSI) in 1992. However, many boys and men still suffer from primary testicular failure due to acquired or genetic causes. New and novel treatments are needed to address these issues. Spermatogenesis originates from spermatogon...
