This is a Health Evidence Network (HEN) synthesis report focusing on the evidence of effective treatment for the types of ill-health from which homeless people often suffer. Homeless people constitute a heterogeneous population characterized by multiple morbidity (primarily alcohol and drug dependence, and mental disorders) and premature mortality. The problems need to be addressed by many meas...

The housing of laying hens is important for social, industrial, and regulatory aspects. Many studies have compared hen housing systems on the research farm, but few have fully examined commercial housing systems and management strategies. The current study compared hens housed in commercial cage-free aviary, conventional cage, and enriched colony cage systems. Environmental and eggshell pool sa...

This is a Health Evidence Network (HEN) synthesis report on the most effective and cost-effective interventions in alcohol control. Evidence shows the most effective approach is to implement a combination of: increases in alcohol prices, reduction in the availability of alcohol, and measures against drunk driving and underage drinking. A report from the Health Evidence Network reviews the evide...

Inteins are parasitic genetic elements that excise themselves at the protein level by self-splicing, allowing the formation of functional, nondisrupted proteins. Many inteins contain a homing endonuclease (HEN) domain and rely on its activity for horizontal propagation. However, successful invasion of an entire population will make this activity redundant, and the HEN domain is expected to dege...

The recombinant antibodies AG275, AG294 and AG274 detect the hen egg-white lysozyme by ELISA.

The recombinant ovalbumin (OVA) produced in yeast Pichia pastoris was purified from the culture medium by anion exchange chromatography, and its structural characteristics were compared with those of hen egg OVA, mainly from the point of view of posttranslational modification. The expressed OVA consisted of two molecular species immmunoreactive with antibody for hen egg OVA. The two molecular s...

The target size of neurotoxic esterase (NTE), the putative target site for the initiation of organophosphorus-compound-induced delayed neurotoxicity, and acetylcholinesterase (AChE) from hen brain were examined by determining the rate at which the activities of the esterases were destroyed by ionizing irradiation. Samples of hen brain were prepared by slowly drying a microsomal preparation unde...

BACKGROUND In Chile, indigenous and non-indigenous schoolchildren have the same stature when they begin school but indigenous adults are shorter, indicating the importance of analyzing growth during puberty. The aim of this study was to compare the growth of indigenous and non-indigenous girls during the 36 months after menarche in Chile's Araucanía Region. METHODS A concurrent cohort study w...

This is a Health Evidence Network (HEN) synthesis report on injuries in children and older people. The evidence of proven and promising strategies for the prevention of unintentional injuries in children and the older people is considerable. Legislative, environmental modification and educational approaches all have a part to play in preventing or reducing childhood injuries, and their interact...

Heat inactivation was studied at 45, 50, 55, and 60 degrees for all of the phenyl valerate hydrolases (PVase), including neurotoxic esterase (NTE) and inhibitor-resistant esterase (IRE), in homogenates of hen or rat brain or in preparations of hen brain microsomal membranes. Hen and rat brain homogenates were prepared in buffer (50 mM Tris/0.20 mM EDTA, pH 8.00, at 25 degrees). Hen brain micros...
