The objective of this study is to assess ambient temperatures' and extreme heat events' contribution to work-related emergency department (ED) visits for hyperthermia in the southeastern United States to inform prevention. Through a collaborative network and established data framework, work-related ED hyperthermia visits in five participating southeastern U.S.

That framework was based on a literature search from 1988-2008 that supported seven categories of climate-related occupational hazards: (1) increased ambient temperature; (2) air pollution; (3) ultraviolet radiation exposure; (4) extreme weather; (5) vector-borne diseases and expanded habitats; (6) industrial transitions and emerging industries; and (7) changes in the built environment. This article reviews the published literature from 2008-2014 in each of the seven categories.

Fibrin sealants promote tissue adherence by crosslinking with extracellular matrix proteins, which may reduce the dead space under skin flaps.
Objectives: The authors evaluate the safety and efficacy of the fibrin sealant (FS) VH S/D 4 s-apr (Artiss; Baxter Healthcare Corp, Deerfield, Illinois), added to standard-of-care (SoC) treatment, in improving flap adherence and reducing dead space in patients undergoing rhytidectomy.

Objectives: The authors evaluate the safety and preliminary efficacy of the fibrin sealant (FS) VH S/D 4 s-apr (ARTISS; Baxter Healthcare Corp, Deerfield, Illinois), added to standard-of-care (SoC) treatment, on tissue plane adherence and local hemostasis in rhytidectomy patients.
Ketosis is estimated to affect 15% of early lactation dairy cows. A ketone test strip (Keto-Test; Elanco Animal Health, Greenfield, IN) allows producers a method to determine the concentration of β-hydroxybutyrate (BHBA) in milk to track individual animal and herd incidence of ketosis. The objective of this study was to determine the effect of altering the temperature of milk and the test strips at the time of the test on the reliability of the Keto-Test.

Methods: Personal airborne lead sampling results in IMIS were extracted for years 1979-2008.
The essential purpose of public health surveillance is to monitor important health outcomes and risk factors and provide actionable information to practitioners, policy makers, researchers, and the public to prevent or ameliorate exposure, disease, and death. Although separate 1970s-era acts of Congress made possible the creation of modern occupational health and environmental public health surveillance, these acts also led to fragmented responsibilities and unconnected data across federal agencies. Having a well-defined purpose for systematically collecting relevant data is key, and state and local programs play a crucial role in conducting meaningful surveillance and connecting it with evidence-based outreach and interventions.

This article reviews the anatomy of the lower face in light of approach and techniques for prejowl implant. Implant sizing, patient selection and analysis, technique, and complications are presented. The author cites the manner of aging in the lower face and discusses the concept of augmenting the mandible to re-establish a youthful contour by correcting the prejowl sulcus and chin for rejuvenation.

The community was concerned about the possibility of childhood exposure to heavy metals from a large nearby smelter because historical environmental and biological sampling data demonstrated the potential for study cohort members to have been exposed to heavy metals during their pre-adolescent years. One cohort had no reported cases of MS.

The acd mutant gene has been mapped just proximal to oligosyndactyly (Os) and esterase-1 (Es-1) in the central region of chromosome 8. Both male and female acd/acd mice are characterized by reduced survival, retarded growth, skin hyperpigmentation, poorly developed pelage and focal ureteral blockage leading to hydronephrosis.

Polyamines are known to influence the growth and function of the seminal vesicles (SV). Furthermore, ornithine decarboxylase (ODC) is considered a key enzyme in the biosynthesis of polyamines and is regulated by PRL in certain target tissues.

There were significant reciprocal differences between the F1 females in the responses of their unfertilized eggs to both enzymes. The F1 hybrids from BALB mothers showed the increased susceptibility characteristic of C57BL whilst the F1 hybrids with C57BL mothers were more resistant to both enzymes, like BALB mice.

The two recessive mutations studied were beige (bg) and reduced pigmentation (rp). Homozygosity for either significantly increased the sleeping time of both sexes after treatment with pentobarbital, tribromoethanol or the steroid anaesthetic alphaxalone.

Absolute testicular weight did not increase between 60 and 120 days of age in either C57BL/6By or C57BL/10ScSn mice but did in BALB mice, paralleling changes in the size of the seminiferous tubules. Significant testicular growth took place over this age period in mice of all seven of the CXB recombinant-inbred (RI) strains of mice derived from a cross of the BALB/cBy and C57BL/6By strains.
View Article and Find Full Text PDFEvidence for genomic imprinting, in which the expression of genes is influenced by their parental origin, is provided by pronuclear transplantation experiments, by studies of X-chromosome inactivation and monoparental disomy, and by the analysis of the expression and methylation of certain transgenes. Both patroclinous and matroclinous patterns of mammalian inheritance occur, and germ-cell and gonadal traits as well as tumor development can be affected. To understand the processes that influence genetic inheritance, genomic imprinting must be distinguished from Y-linkage and cytoplasmic and other maternal effects.

At Day 13, CXB F1 fetuses, with C57 fathers and BALB mothers, had significantly larger testes and ovaries than did fetuses of the other 5 stocks. On Day 16, BALB fetuses had significantly larger testes than did C57, while at Day 19 C57 fetuses had significantly larger testes than did BALB fetuses.
