Bone marrow adipose tissue (MAT) is negatively associated with bone mass. Since osteoblasts and adipocytes are derived from the same precursor cells, adipocyte differentiation may occur at the expense of osteoblast differentiation. We used MAT-deficient KitW/W-v (MAT-) mice to determine if absence of MAT reduced bone loss in hindlimb-unloaded (HU) mice. Male MAT- and wild-type (WT) mice were ra...

OBJECTIVES Brucellosis is one of the most common zoonoses in the world, and occurs mainly in farmers, slaughterhouse workers, and veterinarians via direct or indirect contact with infected animals or their products. The clinical symptoms of human brucellosis are nonspecific, such as fever, headache, chills, and sweating. Diagnosis and treatment of brucellosis requires laboratory tests. Although...

Studies were conducted in large arenas and simulated kitchens to compare the effectiveness of eight traps (seven sticky traps and one jar trap) and Þve attractants formonitoringGerman cockroaches (Blattella germanica L.). The evaluated traps were Trapper (type 9110Ð1), Catchmaster 150, 1001, and 2881, Victor-M330, Victor-M327, Glue board in D-Sect station, and a baby food jar trap. In choice te...

fertility status and distribution of mating type alleles of gibberella moniliformis and g. intermedia, both the causal agents of the foot rot and bakanae of rice, as well as stalk and root rot of corn were studied using specific primers. one hundred and twenty eight single-spore isolates were collected from rice growing areas of guilan and mazandaran and from various corn-growing areas of iran....

background: toxoplasma gondii can infect all warm-blooded animals. modified agglutination test (mat) and elisa are widely used for the detection of t. gondii antibodies. however, there is little information on their acceptability for detecting antibodies in companion animals. methods: this study compared elisa and mat for their ability to detect t. gondii infection in natu­rally infected dogs a...

The heterothallic fungus Podospora anserina has two mating-type alleles termed mat+ and mat-. The mat+ sequence contains one gene, FPR1, while mat- contains three genes: FMR1, SMR1, and SMR2. FPR1 and FMR1 are required for fertilization, which is followed by mitotic divisions of the two parental nuclei inside the female organ. This leads to the formation of plurinucleate cells containing a mixt...

Pineapple production in Costa Rica increased nearly 300-fold during the last 30 yr, and >40,000 hectares of land are currently dedicated to this crop. At the end of the pineapple cropping cycle, plants are chopped and residues incorporated into the soil in preparation for replanting. Associated with increased pineapple production has been a large increase in stable fly, Stomoxys calcitrans (L.)...

Research Roundup Research Roundup for example, two nearby cells can somehow tell which one is closer to the equator (middle) of the eye, and specify the R3 (equatorial) and R4 (polar) fates, accordingly. " This is one of the great puzzles of PCP, " says Simon. " The cells are reading the gradient rather than the absolute values, and sensing the smallest differences. " For that process to have a...
