genetic typing methods of t. gondii strains have been extensively perfected in recent years. from a technical point of view, many tools usable for genetic studied on single-copy loci have been used: rflp, pcr-rflp, sequencing, rapd-pcr and isoenzyme analysis. we described the cloning and sequence analysis of the gene which encodes the major surface antigen (sag1 or p30) of t. gondii. sag1 is th...
In common with other positive-strand RNA viruses, replication of feline calicivirus (FCV) results in rearrangement of intracellular membranes and production of numerous membrane-bound vesicular structures on which viral genome replication is thought to occur. In this study, bioinformatics approaches have identified three of the FCV non-structural proteins, namely p32, p39 and p30, as potential ...
OBJECTIVE: To verify the effects of malnutrition and nutritional rehabilitation regarding seizure threshold, body weight and brain weight in rats. METHODS: Pregnant Wistar rats and their pups were used. Part of the rat pups were submitted to a malnutrition protocol and the rest served as nourished controls. At P15, malnourished and control rats were submitted to status epilepticus induced by fl...
“We thank all the study participants. For technical assistance we thank Kuo Yang and members of the UNC Clinical Trials Unit, the UNC CFAR Immunology Core and the UNC Flow Cytometry Core Facility. This study was supported by NIH grants to the Collaboratory of AIDS Researchers for Eradication (CARE; U19 AI096113) and the UNC Center for AIDS Research (CFAR; P30 AI50410). This research was also su...
The satellite tobacco necrosis virus RNA is uncapped and requires a 3' translational enhancer domain (TED) for translation. Both in the wheat germ extract and in tobacco, TED stimulates in cis translation of heterologous, uncapped RNAs. In this study we investigated to what extent translation stimulation by TED depends on binding to wheat germ factors. We show that in vitro TED binds at least s...
The synthesis of melatonin in Xenopus retinas, chick and quail retinal cell cultures, and Y79 human retinoblastoma cells is stimulated by cAMP through a protein synthesis-dependent mechanism. In Y79 retinoblastoma cells, combined treatment with the RNA synthesis inhibitor camptothecin and agents that elevate cAMP, such as forskolin, causes a synergistic elevation of melatonin. Using two-dimensi...
The present series of studies was designed to provide a general overview of the development of the region connecting the olfactory bulb to the forebrain. The olfactory peduncle (OP) contains several structures involved in processing odor information with the anterior olfactory nucleus (cortex) being the largest and most studied. Results indicate that considerable growth occurs in the peduncle f...
Accumulating evidences indicate that different long non-coding RNAs (lncRNAs) might play a relevant role in tumorigenesis, with their expression and function already associated to cancer development and progression. CCAAT/enhancer-binding protein-α (CEBPA) is a critical regulator of myeloid differentiation whose inactivation contributes to the development of acute myeloid leukemia (AML). Mutati...
Hormonal differences between fathers and non-fathers may reflect an effect of paternal care on hormones. However, few studies have evaluated the hormonal responses of fathers after interacting with their offspring. Here we report results of a 30-minute in-home experiment in which Filipino fathers played with their toddlers and consider whether paternal experience and men's perceptions of themse...
In a further genetic study of murine leukemia virus (MuLV) and its components we examined the backcross C57L X (C57L X AKR). This population was selected because strains AKR and C57L are both Fv-1n, and the restriction which the Fu-1b allele imposes on the output of virus was thereby obviated. The segregants were scored for three characters: (a) infectious Gross-AKR-type MuLV (V), in the tail; ...
