Mrs. J. Palmer Lockwood Journal - Accession 34 - M10 (20)

The Mrs. J. Palmer Lockwood Journal consists of a 76 page journal kept by Mrs. J. Palmer (Leize) Lockwood concerning how the poem Carolina by Henry Timrod became the South Carolina state song. There is also a description of how Mrs. Lockwood worked to popularize the song, three copies of Timrod’s poem, and a copy of a poem titled “Carolina” by Mary Frances Wickliffe, Winthrop faculty member from 1895 to 1919.

Thomas Spratt Memoir - Accession 50 M23 (34)

The Thomas Spratt Memoir consists of a typescript account titled Recollections of the Spratt Family, detailing the history of the Spratt family of York County, South Carolina from the arrival in America of Thomas Spratt from County Down, Ireland, in 1740 to 1876.

The young stellar cluster [DBS2003] 157 associated with the H ii region GAL 331.31-00.34

We report a study of the stellar content of the near-infrared (NIR) cluster [DBS2003] 157 embedded in the extended H ii region GAL 331.31-00.34, which is associated with the IRAS source 16085-5138. JHK photometry was carried out in order to identify potential ionizing candidates, and the follow-up NIR spectroscopy allowed the spectral classification of some sources, including two O-type stars. A combination of NIR photometry and spectroscopy data was used to obtain the distance of these two stars, with the method of spectroscopic parallax: IRS 298 (O6 V, 3.35 +/- 0.61 kpc) and IRS 339 (O9 V, 3.24 +/- 0.56 kpc). Adopting the average distance of 3.29 +/- 0.58 kpc and comparing the Lyman continuum luminosity of these stars with that required to account for the radio continuum flux of the H ii region, we conclude that these two stars are the ionizing sources of GAL 331.31-00.34. Young stellar objects (YSOs) were searched by using our NIR photometry and mid-infrared (MIR) data from the Galactic Legacy Infrared Mid-Plane Survey Extraordinaire (GLIMPSE) survey. The analysis of NIR and MIR colourcolour diagrams resulted in 47 YSO candidates. The GLIMPSE counterpart of IRAS 16085-5138, which presents IRAS colour indices compatible with an ultracompact H ii region, has been identified. The analysis of its spectral energy distribution between 2 and m revealed that this source shows a spectral index a= 3.6 between 2 and m, which is typical of a YSO immersed in a protostellar envelope. Lower limits to the bolometric luminosity and the mass of the embedded protostar have been estimated as L= 7.7 x 10(3) L? and M= 10 M?, respectively, which correspond to a B0B1 V zero-age main sequence star.

The phenotype of Floating-Harbor syndrome: clinical characterization of 52 individuals with mutations in exon 34 of SRCAP

Background Floating-Harbor syndrome (FHS) is a rare condition characterized by short stature, delays in expressive language, and a distinctive facial appearance. Recently, heterozygous truncating mutations in SRCAP were determined to be disease-causing. With the availability of a DNA based confirmatory test, we set forth to define the clinical features of this syndrome. Methods and results Clinical information on fifty-two individuals with SRCAP mutations was collected using standardized questionnaires. Twenty-four males and twenty-eight females were studied with ages ranging from 2 to 52 years. The facial phenotype and expressive language impairments were defining features within the group. Height measurements were typically between minus two and minus four standard deviations, with occipitofrontal circumferences usually within the average range. Thirty-three of the subjects (63%) had at least one major anomaly requiring medical intervention. We did not observe any specific phenotype-genotype correlations. Conclusions This large cohort of individuals with molecularly confirmed FHS has allowed us to better delineate the clinical features of this rare but classic genetic syndrome, thereby facilitating the development of management protocols.

Análise de força muscular e composição corporal de mulheres com Síndrome dos Ovários Policísticos

OBJETIVOS: Comparar os parâmetros metabólicos, a composição corporal e a força muscular de mulheres com Síndrome dos Ovários Policísticos (SOP) em relação a mulheres com ciclos menstruais ovulatórios. MÉTODOS: Estudo caso-controle com 27 mulheres com SOP e 28 mulheres controles com ciclos ovulatórios, com idade entre 18 e 37 anos, índice de massa corpórea entre 18 e 39,9 kg/m², que não praticassem atividade física regular. Níveis séricos de testosterona, androstenediona, prolactina, globulina carreadora dos hormônios sexuais (SHBG), insulina e glicemia foram avaliados. Índice de andrógeno livre (FAI) e resistência insulina (por HOMA) foram calculados. As voluntárias submetidas avaliação de composição corporal por dobras cutâneas e absorciometria de raio X de dupla energia (DEXA) e testes de força muscular máxima de 1-RM em três exercícios após procedimento de familiarização e de força isométrica de preensão manual. RESULTADOS: Os níveis de testosterona foram mais elevados no grupo SOP em relação ao CO (68,0±20,2 versus 58,2±12,8 ng/dL; p=0,02), assim como o FAI (282,5±223,8 versus 127,0±77,2; p=0,01), a insulina (8,4±7,0 versus 4,0±2,7 uIU/mL; p=0,01), e o HOMA (2,3±2,3 versus1,0±0,8; p=0,01). O SBHG foi inferior no grupo SOP comparado ao controle (52,5±43,3 versus 65,1±27,4 nmol/L; p=0,04). Não foram observadas diferenças significativas na composição corporal com os métodos propostos entre os grupos. O grupo SOP apresentou maior força muscular no teste de 1-RM nos exercícios supino reto (31,2±4,75 versus 27,8±3,6 kg; p=0,04) e cadeira extensora (27,9±6,2 versus 23,4±4,2 kg; p=0,01), assim como nos testes de força isométrica de preensão manual (5079,6±1035,7 versus 4477,3±69,6 kgf/m²; p=0,04). Ser portadora de SOP foi um preditor independente de aumento de força muscular nos exercícios supino reto (estimativa (E)=2,7) (p=0,04) e cadeira extensora (E=3,5) (p=0,04). Assim como o IMC no exercício de força isométrica de preensão manual do membro dominante (E=72,2) (p<0,01), supino reto (E=0,2) (p=0,02) e rosca direta (E=0,3) (p<0,01). Nenhuma associação foi encontrada entre HOMA-IR e força muscular. CONCLUSÕES: Mulheres com SOP apresentam maior força muscular, sem diferença na composição corporal. A RI não esteve associada ao desempenho da força muscular. Possivelmente, a força muscular pode estar relacionada aos níveis elevados de androgênios nessas mulheres.

Non-HFE hemochromatosis

Hereditary hemochromatosis (HH) is an autosomal recessive disorder classically related to HFE mutations. However, since 1996, it is known that HFE mutations explain about 80% of HH cases, with the remaining around 20% denominated non-HFE hemochromatosis. Nowadays, four main genes are implicated in the pathophysiology of clinical syndromes classified as non-HFE hemochromatosis: hemojuvelin (HJV, type 2Ajuvenile HH), hepcidin (HAMP, type 2B juvenile HH), transferrin receptor 2 (TFR2, type 3 HH) and ferroportin (SLC40A1, type 4 HH). The aim of this review is to explore molecular, clinical and management aspects of non-HFE hemochromatosis.
