Apolipoprotein E Induces Lipid Accumulation Through Dgat2 That Is Prevented with Time-Restricted Feeding in .

Apolipoprotein E (ApoE) is the leading genetic risk factor for late-onset Alzheimer's disease (AD), which is the leading cause of dementia worldwide. Most people have two ApoE-ε3 (ApoE3) alleles, while ApoE-ε2 (ApoE2) is protective from AD, and ApoE-ε4 (ApoE4) confers AD risk. How these alleles modulate AD risk is not clearly defined, and ApoE's role in lipid metabolism is also not fully known.

Hydrocephalus in a rat model of Meckel Gruber syndrome with a TMEM67 mutation.

Transmembrane protein 67 (TMEM67) is mutated in Meckel Gruber Syndrome type 3 (MKS3) resulting in a pleiotropic phenotype with hydrocephalus and renal cystic disease in both humans and rodent models. The precise pathogenic mechanisms remain undetermined. Herein it is reported for the first time that a point mutation of TMEM67 leads to a gene dose-dependent hydrocephalic phenotype in the Wistar polycystic kidney (Wpk) rat.

School nursing on the iron range in a public health nursing model.

Frontier nursing in the public health model might invoke images of school nurses on horseback in rural Kentucky or the wilds of the western prairies. Northern Minnesota was a frontier in the last decade of the 19th century, due to the discovery of one of the richest seams of iron ore on the North American continent. Immigrants from Europe responded to the opportunities this discovery created.

The WAG1 and WAG2 protein kinases negatively regulate root waving in Arabidopsis.

The WAG1 and WAG2 genes of Arabidopsis thaliana encode protein-serine/threonine kinases that are closely related to PINOID. In order to determine what roles WAG1 and WAG2 play in seedling development, we used a reverse genetics approach to study the wag1, wag2 and wag1/wag2 mutant phenotypes for clues. Although the wag mutants do not contain detectable amounts of the corresponding mRNA, they are wild type in most respects.

Giardiasis surveillance--United States, 1998-2002.

Problem/condition: Giardiasis, a gastrointestinal illness, is caused by the protozoan parasite Giardia intestinalis.

Reporting Period: 1998-2002.

System Description: State, commonwealth, territorial, and two metropolitan health departments voluntarily reported cases of giardiasis through CDC's National Electronic Telecommunications System for Surveillance.

Cryptosporidiosis surveillance--United States 1999-2002.

Problem/condition: Cryptosporidiosis, a gastrointestinal illness, is caused by protozoa of the genus Cryptosporidium.

Reporting Period: 1999-2002.

System Description: State and two metropolitan health departments voluntarily reported cases of cryptosporidiosis through CDC's National Electronic Telecommunications System for Surveillance.

Phytochrome regulation of pea phototropin.

Type 1 phototropin, one of the blue light receptors responsible for phototropism, is encoded in peas by at least two genes, PsPHOT1A and PsPHOT1B (formerly PsPK4 and PsPK5), both of which are more similar to Arabidopsis PHOT1 than to Arabidopsis PHOT2. We show here that PsPHOT1B encodes a full-length phototropin, whose expression pattern suggests that Psphot1b is the predominant phot1-type phototropin in etiolated seedlings. The gene encoding the other type 1 phototropin, PsPHOT1A, is expressed at low levels, with its highest levels in the leaves and stems of more mature, light-grown plants.

Public health nursing pioneer: Jane Elizabeth Hitchcock 1863-1939.

Jane Elizabeth Hitchcock was one of many distinguished nursing leaders of the 19th and early 20th centuries who attended a women's college before enrolling in a nurse training school. Like many of her contemporaries with equally impeccable family credentials, Hitchcock was something of an enigma to her family for choosing nursing over teaching, the most common acceptable career for women of her social class. Hitchcock's endowment of character, according to contemporary Lavinia Dock, exemplified the best of her Puritan roots.

SIX INDEPENDENT LOSSES OF THE CHLOROPLAST DNA rpl2 INTRON IN DICOTYLEDONS: MOLECULAR AND PHYLOGENETIC IMPLICATIONS.

Previous studies have shown that in several angiosperms and the liverwort Marchantia the chloroplast gene rpl2, encoding ribosomal protein L2, is interrupted by an intron, but that in spinach (Spinacia oleracea, Caryophyllales) this intron has been lost. We have determined the distribution of the rpl2 intron for 390 species representing 116 angiosperm families. Filter hybridizations reveal that the intron is absent from the chloroplast genomes of all examined families of the Caryophyllales, suggesting that the intron was lost in the common ancestor of the order.
