Mid-late Holocene monsoon climate retrieved from seasonal Sr/Ca and delta O-18 records of Porites lutea corals at Leizhou Peninsula, northern coast of South China Sea

South China Sea (SCS) is a major moisture source region, providing summer monsoon rainfall throughout Mainland China, which accounts for more than 80% total precipitation in the region. We report seasonal to monthly resolution Sr/Ca and delta(18)O data for five Holocene and one modem Porites corals, each covering a growth history of 9-13 years. The results reveal a general decreasing trend in sea surface temperature (SST) in the SCS from similar to 6800 to 1500 years ago, despite shorter climatic cycles. Compared with the mean Sr/Ca-SST in the 1990s (24.8 degrees C), 10-year mean Sr/Ca-SSTs were 0.9-0.5 degrees C higher between 6.8 and 5.0 thousand years before present (ky BP), dropped to the present level by similar to 2.5 ky BP, and reached a low of 22.6 degrees C (2.2 degrees C lower) by similar to 1.5 ky BP. The summer Sr/Ca-SST maxima, which are more reliable due to faster summer-time growth rates and higher sampling resolution, follow the same trend, i.e. being 1-2 degrees C higher between 6.8 and 5.0 ky BP, dropping to the present level by -2.5 ky BP, and reaching a low of 28.7 degrees C (0.7 degrees C lower) by similar to 1.5 ky BP. Such a decline in SST is accompanied by a similar decrease in the amount of monsoon moisture transported out of South China Sea, resulting in a general decrease in the seawater delta(18)O values, reflected by offsets of mean 6 180 relative to that in the 1990s. This observation is consistent with general weakening of the East Asian summer monsoon since early Holocene, in response to a continuous decline in solar radiation, which was also found in pollen, lake-level and loess/paleosol records throughout Mainland China. The climatic conditions similar to 2.5 and similar to 1.5 ky ago were also recorded in Chinese history. In contrast with the general cooling trend of the monsoon climate in East Asia, SST increased dramatically in recent time, with that in the 1990s being 2.2 degrees C warmer than that similar to 1.5 ky ago. This clearly indicates that the increase in the concentration of anthropogenic greenhouse gases played a dominant role in recent global warming, which reversed the natural climatic trend in East Asian monsoon regime.

Clay mineralogical and isotopic (K-Ar, delta O-18, delta D) constraints on the evolution of the North Anatolian Fault Zone, Turkey

This study presents the first attempt to constrain the evolution of the North Anatolian Fault Zone (NAFZ) by age dating and isotope tracing of clay minerals formed during near-surface faulting. Extensive illitic clay mineralisation occurred along the NAFZ related to hydrothermal alteration of the fault gouges and pseudotachylytes. Samples representing the pre-fault protoliths outside the fault zone do not contain authigenic illitic clay minerals indicating that hydrothermal processes were confined to the areas within the fault zone. K-Ar age data indicate that the hydrothermal system and the associated illite authigenesis initiated at similar to 57 Ma. This process is interpreted to reflect the onset of significant strike-slip or transtensional faulting immediately after the continental collision related to the closure of the Neotethys Ocean. Following the initiation of the fault movements in the latest Paleocene-Early Eocene, displacements along the NAFZ have continued, with probably intensified fault activities at similar to 26 Ma and later than similar to 8 Ma. Oxygen isotope compositions of the illitic clays from different locations along the NAFZ are similar, with narrow ranges in delta O-18 values indicating clay precipitation from fluids with similar oxygen isotope compositions and crystallisation temperatures. The delta O-18 and delta D values of the calculated fluid isotopic composition (delta O-18=5.9 parts per thousand to 11.2 parts per thousand, delta D=-59 parts per thousand to -73 parts per thousand) are consistent with metamorphic and magmatic origin of fluids mobilised during active tectonism. The interpretation of the fluid flow history of the NAFZ is in agreement with that reported previously for some well-known large-scale high-angle fault zones, which similarly developed along collisional-type orogenic belts and are commonly associated with significant mesothermal ore mineralisation.

Inappropriate oral formulations and information in paediatric trials

Previously, quality of formulations information provided for oral medications used in paediatric clinical trials published in 10 highly cited journals between 2002 and 2004 raised concerns. This short report explores if there was any subsequent improvement on how the formulations used in trials involving children

Formulation design considerations for oral vaccines

Whilst oral vaccination is a potentially preferred route in terms of patient adherence and mass vaccination, the ability to formulate effective oral vaccines remains a challenge. The primary barrier to oral vaccination is effective delivery of the vaccine through the GI tract owing to the many obstacles it presents, including low pH, enzyme degradation and bile-salt solubilization, which can result in breakdown/deactivation of a vaccine. For effective immune responses after oral administration, particulates need to be taken up bythe M cells however, these are few in number. To enhance M-cell uptake, particle characteristics can be optimized with particle size, surface charge, targeting groups and bioadhesive properties all being considerations. Yet improved uptake may not translate into enhanced immune responses and formulating particulates with inherent adjuvant properties can offer advantages. Within this article, we establish the options available for consideration when building effective oral particulate vaccines.

Relationship between changes in postprandial glucagon, patient characteristics, and response to lixisenatide as add-on to oral antidiabetics

Background and aims: Lixisenatide, a once-daily prandial glucagon-like peptide-1 receptor agonist, reduces postprandial (PP) glycaemic excursions and HbA 1c . We report an exploratory analysis of the GetGoal-M and S trials in patients with type 2 diabetes mellitus (T2DM) with different changes in PP glucagon levels in response to lixisenatide treatment. Materials and methods: Patients (n=423) were stratified by their change in 2 hour PP glucagon level between baseline evaluation and Week 24 of treat - ment with lixisenatide as add-on to oral antidiabetics (OADs) into groups of Greater Change (GC; n=213) or Smaller Change (SC; n=210) in plasma glucagon levels (median change -23.57 ng/L). ANOVA and Chi-squared tests were used for the comparison of continuous and categorical variables, respec - tively. Baseline and endpoint continuous measurements in each group were compared using paired t -tests. Results: Mean change from baseline in 2 hour PP glucagon levels for the GC vs SC groups was -47.19 vs -0.59 ng/L (p<0.0001), respectively. Patients in the GC group had a shorter mean duration of diabetes (7.3 vs 9.0 years; p=0.0036) and lesser OAD use (4.5 vs 5.7 years; p=0.0092) than those in the SC group. Patients in the GC group had a greater mean reduction in HbA 1c (-1.10 vs -0.67%; p<0.0001), fasting plasma glucose (FPG; -25.20 vs -9.30 mg/dL [p<0.0001]), PP plasma glucose (PPG; -129.40 vs -78.22 mg/dL [p<0.0001]), and a greater drop in weight (-2.27 vs -1.17 kg; p=0.0002) and body mass index (-0.84 vs -0.44 kg/m 2 ; p=0.0002) than those in the SC group. More patients in the GC group also achieved composite endpoints, including HbA 1c <7% with no symptomatic hypoglycaemia and no weight gain (40.38 vs 19.52%; p<0.0001), than in the SC group. Conclusion: Greater reductions in PP glucagon associated with lixisenatide as add-on to OADs in patients with T2DM are also associated with greater reductions in HbA1c, FPG, PPG, and greater weight loss, highlighting the importance of glucagon suppression on therapeutic response.

Efeitos da suplementação oral de zinco sobre o crescimento de crianças pré-púberes saudáveis e eutróficas

Introdução: o zinco é um importante micronutriente para numerosos processos bioquímicos em animais e humanos, desempenhando papel de destaque no crescimento e desenvolvimento. Em populações mundiais, a deficiência primária grave de zinco não é comum, embora, a deficiência leve seja bastante prevalente. Considerando que o zinco é essencial para a saúde humana e regula o sistema hipotálamo, hipófise, fígado e osso, buscamos averiguar os seus efeitos no eixo GH-IGF1-IGFBP3 agudamente, mediante administração intravenosa com o elemento zinco, e cronicamente, mediante suplementação oral com o elemento zinco, usando doses fisiológicas de 0.06537 mg Zn/kg (via intravenosa) e 10 mg Zn/dia (via oral). A inclusão de crianças pré-púberes aparentemente saudáveis e eutróficas sem deficiência de zinco é raro na literatura, pois grande parte das publicações foram reportadas em crianças apresentando deficiência de zinco. A metodologia aplicada foi absolutamente inovadora e original, tornando o estudo altamente relevante para a interface entre endocrinologia e nutrição. Objetivo: investigar os efeitos da suplementação oral e administração intravenosa com o elemento zinco sobre a secreção de GH, IGF1, IGFBP3, OCN, ALP, TRAP e PT em crianças aparentemente saudáveis e eutróficas sem deficiência de zinco. Métodos: o estudo foi conduzido durante um período de três meses, e caracterizado por ser randomizado controlado triplo cego. As crianças foram selecionadas por amostragem não probabilística de conveniência, provenientes de escolas públicas municipais, de ambos os gêneros, na faixa etária compreendida entre 8 e 9 anos de idade, divididas em grupo controle (20 crianças recebendo solução placebo contendo 10% de sorbitol) e grupo experimental (20 crianças suplementadas com o elemento zinco na forma de sulfato de zinco heptahidratado – ZnSO4.7H2O). As crianças foram submetidas à suplementação oral de zinco elementar (10 mg Zn/dia) e à administração intravenosa de zinco (0.06537 mg Zn/kg de peso corporal), na forma de ZnSO4.7H2O, cujas amostras sanguíneas foram coletadas em 0, 60, 120, 180 e 210 minutos. Foram realizadas avaliações antropométricas e dietéticas e dosagens bioquímicas e hormonais nas crianças estudadas. Resultados: após a suplementação oral, foi observado no grupo experimental (i) aumento significativo dos valores de ingestão de energia total, proteína e gordura total (p = 0.0007, p< 0.0001, p< 0.0001, respectivamente), (ii) aumento significativo do zinco sérico basal (p< 0.0001), aumento significativo das concentrações plasmáticas de fostatase alcalina (p = 0.0270), e (iv) correlação positiva com o IGF1, IGFBP3, OCN, comparando antes e após a suplementação (p = 0.0011, p< 0.0001, p< 0.0446, respectivamente). Durante a administração venosa de zinco, as concentrações plasmáticas de IGF1 e IGFBP3 aumentaram significativamente no grupo experimental (p = 0.0468, p < 0.0001, respectivamente). Em relação o cálculo da adequação aparente, segundo as DRI, para o cálcio, houve inadequação da dieta com 85% de confiabilidade dos dados; para o ferro, adequação da dieta, com 85% de confiabilidade dos dados. Para o zinco, adequação da dieta, com 50% de confiabilidade dos dados. Conclusões: a suplementação oral com o elemento zinco pode ter estimulado um aumento na ingestão de energia total, proteína e gordura total, assim como, nas concentrações basais de zinco sérico e nas concentrações plasmáticas de fosfatase alcalina. A administração intravenosa de zinco aumentou as concentrações séricas de zinco e as concentrações plasmáticas de GH, IGF1 e IGFBP3 no grupo experimental.

Immunohistochemical expression of nuclear factor B, matrix metalloproteinase 9, and endoglin (CD105) in odontogenic keratocysts, dentigerous cysts, and radicular cysts

OBJECTIVE: The aim of this study was to compare the immunohistochemical expression of nuclear factor κB (NF-κB), matrix metalloproteinase 9 (MMP-9), and CD105 in odontogenic keratocysts (OKCs), dentigerous cysts (DCs), and radicular cysts (RCs). STUDY DESIGN: Twenty cases of OKCs, 20 DCs, and 20 RCs were analyzed. A labeling index (LI), which expresses the percentage of NF-κB-stained nuclei, was calculated for the analysis of NF-κB expression. Expression of MMP-9 in the epithelium and in the capsule of each lesion was scored as 0 (<10% stained cells), 1 (10%-50% stained cells), or 2 (>50% stained cells). In addition, MMP-9 immunostaining was analyzed in endothelial cells of vessels with a conspicuous lumen. The angiogenic index was determined based on the number of anti-CD105 antibody-stained microvessels. RESULTS: In the epithelial component, the NF-κB LI was higher in OKCs than in DCs and RCs (P < .001). Analysis of MMP-9 expression in the epithelial component showed a predominance of score 2 in OKCs (90%), DCs (70%), and RCs (65%; P = .159). Evaluation of the NF-κB LI according to the expression of MMP-9 in the epithelial lining revealed no significant difference between lesions (P = .282). In the fibrous capsule, the highest percentage of MMP-9-stained cells (score 2) was observed in OKCs (P = .100). Analysis of the expression of MMP-9 in the vessels of odontogenic cysts showed a predominance of score 2 in OKCs (80%) and RCs (50%) and of score 1 in DCs (75%; P = .002). Mean microvessel count was high in RCs (16.9), followed by DCs (12.1) and OKCs (10.0; P = .163). No significant difference in microvessel count according to the expression of MMP-9 was observed between groups (P = .689). CONCLUSIONS: The results suggest that the more aggressive biologic behavior of OKCs is related to the higher expression of MMP-9 and NF-κB in those lesions. The differences in the biologic behavior of the lesions studied do not seem to be associated with the angiogenic index.

A produção oral de inglês como LE em uma escola pública de Natal: uma experiência com a abordagem baseada em tarefas

The aim of this action research of mixed-methods was investigating the role of the tasks proposed by the Task-Based Learning, TBL (WILLIS, 1996) in the process of development of speech production in English as a foreign language (EFL) at the public school. Twenty-three students from a grade of secondary school from a state school in Rio Grande do Norte were exposed systematically to the implementation of the learning tasks focused in the speech production in EFL during two months. The instruments used at the data collection – pre and post-questionnaire; field notes; focal group; and pre and post-tests - generated two kinds of data: a) qualitative (the perception of the students about their speech production and the teaching of this ability at the public school; and, the usage of strategies of communication for these learners facing TBL); and, b) quantitative (the development of pronunciation; of accuracy in the proficiency tests (test KET – Cambridge, adapted); and, of Global Oral Proficiency (POG) of these learners after the accomplishment of the learning tasks). The quantitative results of the study indicate that there was a statistically significant development of pronunciation and accuracy at the proficiency tests, after the tasks experience. The qualitative findings, in turn, represented by the learners‟ reports and from the research teacher, show that there has been greater focus on the use of communicative strategies during the learners‟ oral production throughout the intervention with the tasks.

Correlação da imunoexpressão do fator de choque térmico 1 (hsf1) com aspectos clinicopatológicos em carcinomas de células escamosas de língua oral

Squamous cell carcinoma of oral tongue shows high rates of morbidity and mortality in the population, therefore, great efforts are being made to classify morphological changes and identify biomarkers that have prognostic value and that are able to group patients in individualized therapeutic options. From this perspective, there is the heat shock factor 1 (HSF1), which is a heat shock factor transcription protein (HSPs) that allows the cancer to deal with stressors associated with malignancy, acting differently in tumor progression. This research aimed to perform a clinico-pathological analysis of 70 cases of oral tongue squamous cell carcinoma (OTSCC) and immunohistochemical study of the expression of HSF1 protein in OTSCC, comparing it with 30 specimens of normal oral mucosa (NOM), and correlating this immunostaining with clinico-pathological aspects of OTSCC. To analyze the association between immunoexpression of HSF1 and clinicophatoloical aspects, the cases were categorized in minor and major overexpression, based in the median immunostaining score. Regarding the cases of OTSCC, 57.1% showed clinical stage III or IV, 82.9% were graded as high grade according to Bryne (1998) and 47.1% as high risk of malignancy according to Brandwein-Gensler et al., (2005). A disease free survival rate of 47.84% and overall survival rate of 68.20% was observed in the analyzed cases, and the high degree of malignancy according to Bryne’s system (1998) (p=0.05), tumor size T3 or T4 (p=0.04), local recurrence (p=0.02), and perineural invasion (p=0.02) determined negative impacts in survival time. We observed also a statistically significant result (p<0.01) when comparing the immunoreactivity of HSF1 between NOM and OTSCC. This significantly increased expression of HSF1 in cases of OTSCC suggests that this protein acts, indeed, in the pathogenesis of this disease. However, there were no statistically significant associations between this overexpression and the clinico-pathological parameters analyzed. This finding may reflect the influence of epigenetic events on HSF1 gene or a possible stability of this protein expression throughout disease progression.

Expressão imuno-histoquímica do ativador de plasminogênio do tipo uroquinase e seu receptor em carcinoma epidermoide de língua oral e sua relação com parâmetros clínico-patológicos

Squamous cell carcinoma (SCC ) is the most common malignancy of the oral cavity (OSCC), with a high mortality rate. Due to this, the discovery of biomarkers that facilitate the understanding of the biological behavior of the tumor and improve treatment is necessary. Urokinase type plasminogen activator (uPA) and its receptor, uPAR, are responsible for the proteolysis of structures of the basement membrana and extracellular matrix, facilitating tumor invasion. This study aims to assess the immuno expression of these proteins in 46 cases of squamous cell carcinoma of the oral tongue (OTSCC). These results were related to the presence of metastasis, clinical TNM staging, locoregional recurrence, outcome of the lesion and histological grading. Immunostaining of each case was evaluated semiquantitatively, in the front of invasion and center of the tumor, in which scores were assigned: 0 (0% of positive cells), 1 (1-10% of positive cells), 2 (11 -50% positive cells) and 3 (more than 50% positive cells). The expression of uPA was observed in 93.5% (n=43) of the cases in the front of invasion, with predominance of score 2 (n=16; 34.8%) and in 67.9% (n=31) of the cases in the center of the tumor, with predominance of score 1 (n=15; 32.6%). Overall, the immunoexpression of uPA was not associated with clinical parameters. Regarding the malignant histological grading, a higher expression of uPA was observed in cases of high-grade malignancy comp ared to low-grade malignancy (p=0.05). Regarding the morphological parameters, increased expression of uPA was observed in the worst mode of invasion (p=0.03 ). The expression of uPAR was observed in 73.9% of cases in the front of invasion, with a predominance of score 1 (n=21; 45.6 %), and in 47.5% (n=21) of the cases in the center of the tumor, with a predominance of score 0 (n=25; 54.4%). Although no statistical differences were observed in relation to lymph node metastasis, clinical TNM staging, outcome, and histological grading, there was a higher expression of uPAR in cases with locoregional recurrence (p=0.04). Regarding the tumor intra -localization, it was observed an increased expression of uPA and uPAR at the front of invasion in relation to the center of the tumor (p<0.001). Regarding the correlation between uPA and uPAR, there was no statistical sign ificance. Based on these results, it is suggested that uPA and uPAR are involved in the progression of CELO, mainly in the deeper region of the tumor.

Métodos de avaliação nutricional para a suplementação oral com zinco em crianças pré-púberes não deficientes em zinco

Background: Zinc is an essential nutrient that is required for numerous metabolic functions, and zinc deficiency results in growth retardation, cellmediated immune dysfunction, and cognitive impairment. Objective: This study evaluated nutritional assessment methods for zinc supplementation in prepubertal nonzinc- deficient children. Design: We performed a randomised, controlled, triple-blind study. The children were divided into a control group (10% sorbitol, n = 31) and an experimental group (10 mg Zn/day, n = 31) for 3 months. Anthropometric and dietary assessments as well as bioelectrical measurements were performed in all children. Results: Our study showed (1) an increased body mass index for age and an increased phase angle in the experimental group; (2) a positive correlation between nutritional assessment parameters in both groups; (3) increased soft tissue, and mainly fat-free mass, in the body composition of the experimental group, as determined using bioelectrical impedance vector analysis; (4) increased consumption of all nutrients, including zinc, in the experimental group; and (5) an increased serum zinc concentration in both groups (p < 0.0001). Conclusions: Given that a reference for body composition analysis does not exist for intervention studies, longitudinal studies are needed to investigate vector migration during zinc supplementation. These results reinforce the importance of employing multiple techniques to assess the nutritional status of populations.
