As a pediatrician, Dr. Giannini prioritizes connecting with children and involving them at the visit or in their care when possible. She is known for spending time with families when they need it and working as a team through important issues. She finds great joy in caring for children as they grow, mature, and move on into their own adult identity. It is especially rewarding to her to care for new generations as former patients bring their new families in for care.

Background: Rituximab added to chemotherapy prolongs survival among adults with B-cell cancer. Data on its efficacy and safety in children with high-grade, mature B-cell non-Hodgkin's lymphoma are limited.

Methods: We conducted an open-label, international, randomized, phase 3 trial involving patients younger than 18 years of age with high-risk, mature B-cell non-Hodgkin's lymphoma (stage III with an elevated lactate dehydrogenase level or stage IV) or acute leukemia to compare the addition of six doses of rituximab to standard lymphomes malins B (LMB) chemotherapy with standard LMB chemotherapy alone. The primary end point was event-free survival. Overall survival and toxic effects were also assessed.

Conclusions: Rituximab added to standard LMB chemotherapy markedly prolonged event-free survival and overall survival among children and adolescents with high-grade, high-risk, mature B-cell non-Hodgkin's lymphoma and was associated with a higher incidence of hypogammaglobulinemia and, potentially, more episodes of infection.

This article is the first of a new series recognizing individuals or organizations that were among the earliest users of GIS—truly pioneers in an unexplored field. These people or organizations understood the advantages of this emerging technology that came to be called geographic information systems and recognized Esri as a viable partner to help them solve their geospatial challenges. Together, these pioneers, partnering with Esri, helped GIS mature into the important multifaceted analysis tool that it is today. Esri recognizes Jacqueline daCosta as a GIS Pioneer.

Developing heifers to reach a target weight of 50% of mature body weight at the beginning of the breeding season is an effective method for reducing heifer development cost. Net costs to produce a bred yearling heifer and 2-year-old cow were lower when heifers were developed to 50% rather than 55% of mature body weight, regardless of breeding season length. Administration of oral progestin to heifers developed to 50% mature body weight prior to breeding did not affect reproductive performance during the first breeding season when heifers were exposed to bulls 13 days after the end of progestin treatment.

Dysregulation of hypothalamic-pituitary-adrenal (HPA) axis activity leads to debilitating neuroendocrine or metabolic disorders such as Cushing's syndrome (CS). Glucocorticoids control HPA axis activity through negative feedback to the pituitary gland and the central nervous system (CNS). However, the cellular mechanisms involved are poorly understood, particularly in the CNS. Here we show that, in mice, selective loss of TrkB signalling in cholecystokinin (CCK)-GABAergic neurons induces glucocorticoid resistance, resulting in increased corticotrophin-releasing hormone expression, chronic hypercortisolism, adrenocortical hyperplasia, glucose intolerance and mature-onset obesity, reminiscent of the human CS phenotype. Interestingly, obesity is not due to hyperphagia or decreased energy expenditure, but is associated with increased de novo lipogenesis in the liver. Our study therefore identifies CCK neurons as a novel and critical cellular component of the HPA axis, and demonstrates the requirement of TrkB for the transmission of glucocorticoid signalling.

Amino acid starvation for a short time period does not affect the nuclear-cytoplasmic distribution of mature tRNAs made from intronless pre-tRNAs in S. cerevisiae. The cells were starved of amino acids in minimal medium containing glucose for the times indicated. The location of tRNALeu, tRNAHis, and tRNAGly was detected by FISH. The arrows indicate the location of nuclei.

Amino acid starvation causes nuclear retention of tRNAIle(UAU) derived from an intron-containing precursor, but not tRNAIle(AAU) made from an intronless pre-tRNA. S. cerevisiae cells were starved of amino acids in synthetic medium containing glucose for 1 h, and the cellular distribution of mature tRNAIle(AAU) (A) and tRNAIle(UAU) (B) was monitored by FISH. The DNA was visualized by DAPI staining. Arrows indicate nuclear accumulated tRNAs that colocalize with DAPI staining.

The onset of nuclear retention of tRNAHis in the histidine, leucine auxotrophic S. cerevisiae strain starved of amino acids occurs later than that for tRNATyr and tRNALeu. S. cerevisiae was incubated in complete minimal medium lacking all amino acids over a 6-h period, and the cellular location of the mature forms of tRNATyr, tRNALeu, tRNAGly, and tRNAHis was monitored by FISH. DAPI staining was used to visualize the nucleus.

The onset of nuclear accumulation of tRNATyr and tRNALeu in the histidine, leucine auxotrophic S. cerevisiae strain starved of histidine only occurs later than that for tRNAHis. S. cerevisiae was incubated in complete minimal medium lacking histidine over a 4-h period, and the cellular location of the mature forms of tRNATyr, tRNALeu, tRNAGly, and tRNAHis was monitored by FISH. Nuclei were visualized by DAPI staining.

Mtr10p is not involved in nuclear import of cytoplasmic spliced tRNAs during amino acid deprivation. The wild-type RS453 (A, C) and mtr10::His3 (B, D) strains were incubated in synthetic media lacking amino acids but containing glucose for 30 min or 120 min. FISH was performed at the indicated time points to monitor the cellular location of mature tRNATyr (A, B) and tRNAGly (C, D), and DNA was visualized using DAPI. The arrows indicate nuclear accumulated tRNAs that colocalize with DAPI staining. The percentage of cells showing nuclear retention of tRNATyr in the RS453 and mtr10::His3 strains during the time course of amino acid starvation was quantified using three different fields from three independent experiments, and the average is plotted in a bar graph (E). To validate the mtr10::His3 strain, the localization of Npl3p-GFP (F) was monitored in the wild-type RS453 and mtr10::His3 strains grown in synthetic complete media containing glucose by fluorescence microscopy. 041b061a72
