Castianeira tinae Patel & Patel 1973
No full textCastianeira tinae Patel & Patel, 1973 Castianeira Tinae Patel & Patel, 1973: 6, fig. 3a–g (♂ ♀). Castianeira tinae: Feng, 1990: 173, fig. 148.1–4 (not ♂, ♀); Majumder & Tikader, 1991: 140, figs 292–296 (♀). Remarks. This species was described based on male and female specimens collected from Vallabh Vidhyanagar (22 o 32’51.56’’N, 72 o 55’30.50’’E; 41 m alt) in Gujarat. The type material of this species was not examined as it is not deposited in NZC-ZSI. It is noteworthy that Patel and Patel (1973) provided no repository information for this species. The original illustrations, even though they are highly schematic, provide hints regarding similarity of this species with Castianeira zetes Simon, 1897, particularly the shape and orientation of the embolus, and outline of the epigyne. The male pedipalp of this species illustrated in Feng (1990: figs 148.3–4) is, however, not of a Castianeira species, but is of Corinnomma severum (Thorell, 1887) (cf. Feng 1990: fig. 148.3 and Deeleman-Reinhold 2001: fig. 469). The subsequent illustrations of the epigyne of C. tinae (Feng 1990: fig. 148.1–2; Majumder & Tikader 1991: figs 293–294) also indicate its resemblance to C. zetes. However, its synonymy with C. zetes can only be confirmed after examining the type specimen of the species.Published as part of Sankaran, Pradeep M., Caleb, John T.

Serum vitamin D and cardiometabolic risk factors in the UK population
No full textLow serum 25-hydroxyvitamin D (25(OH)D) concentrations have been associated with greater adiposity and an adverse cardiometabolic risk profile, yet findings are inconsistent and the role of vitamin D status in cardiovascular disease (CVD) remains uncertain. We aimed to examine the associations between serum 25(OH)D and CVD risk factors in the British population. We analysed data on 2842 subjects aged ≥40 years enrolled in the National Diet and Nutrition Survey (NDNS 2008-2018). Based on serum 25(OH)D concentrations, study subjects were grouped in three categories: vitamin D deficiency (<25 nmol/L), vitamin D insufficiency (25-49 nmol/L) and vitamin D sufficiency status (≥50 nmol/mL). Differences in CVD risk factors between vitamin D deficiency or insufficiency and vitamin D sufficiency status were expressed in standard deviation scores (SDSs) and estimated through weighted multiple linear regression models. We found that vitamin D deficiency was directly associated with BMI, waist circumference, triglycerides and inversely associated with high-density lipoprotein cholesterol (HDL) values. The strongest associations were found between vitamin D deficiency and triglycerides (0.50 SDS, 95% CI: 0.24, 0.77) among men, and vitamin D deficiency and waist circumference (0.70 SDS, 95% CI: 0.56, 0.94), BMI (0.63 SDS, 95% CI: 0.39, 0.88) and triglycerides (0.54 SDS, 95% CI: 0.30, 0.77) among women. When adjusting for BMI the association with triglyceride attenuated (from 0.50 SDS to 0.39 SDS among men and from 0.54 SDS to 0.30 SDS among women). Our data indicates a relationship between inadequate vitamin D status and an adverse CVD risk profile. However, interventional studies are needed to establish possible benefits of vitamin D supplementation on cardiovascular risk. This article is protected by copyright. All rights reserved

The New Deal : A Global History /
No full textThe New Deal: A Global History provides a radically new interpretation of a pivotal period in US history. The first comprehensive study of the New Deal in a global context, the book compares American responses to the international crisis of capitalism and democracy during the 1930s to responses by other countries around the globe-not just in Europe but also in Latin America, Asia, and other parts of the world. Work creation, agricultural intervention, state planning, immigration policy, the role of mass media, forms of political leadership, and new ways of ruling America's colonies-all had parallels elsewhere and unfolded against a backdrop of intense global debates.By avoiding the distortions of American exceptionalism, Kiran Klaus Patel shows how America's reaction to the Great Depression connected it to the wider world. Among much else, the book explains why the New Deal had enormous repercussions on China; why Franklin D. Roosevelt studied the welfare schemes of Nazi Germany; and why the New Dealers were fascinated by cooperatives in Sweden-but ignored similar schemes in Japan.Ultimately, Patel argues, the New Deal provided the institutional scaffolding for the construction of American global hegemony in the postwar era, making this history essential for understanding both the New Deal and America's rise to global leadership.The New Deal: A Global History provides a radically new interpretation of a pivotal period in US history.

Evaluation of the Tauc Method for Optical Absorption Edge Determination: ZnO Thin Films as a Model System
No full textOne of the most frequently used methods for characterizing thin films is UV-Vis absorption. The near-edge region can be fitted to a simple expression in which the intercept gives the band-gap and the fitting exponent identifies the electronic transition as direct or indirect. (See Tauc et al., Physica Status Solidi, 1966; these are often called “Tauc” plots.) While the technique is powerful and simple, the accuracy of the fitted band-gap result is seldom stated or known. We tackle this question by refitting a large number of Tauc plots from the literature and look for trends. Nominally pure zinc oxide (ZnO) was chosen as a material with limited intrinsic deviation from stoichiometry and which has been widely studied. Our examination of the band gap values and their distribution leads to a discussion of some experimental factors that can bias the data and lead to either smaller or larger apparent values than would be expected. Finally, an easily evaluated figure-of-merit is defined that may help guide more accurate Tauc fitting. For samples with relatively sharper Tauc plot shapes, the population yields Eg (ZnO) as 3.276 +/- 0.033 eV, in good agreement with data for single crystalline material.This is the accepted version of the following article: Viezbicke, B.

1,25-dihydroxyvitamin D3 and development of tuberculosis in cattle
No full textThis report describes the presence and activity of 1,25-dihydroxyvitamin D3 (1,25-D3) in experimental bovine tuberculosis. Animals that went on to develop tuberculous lesions exhibited a rapid transient increase in serum 1,25-D3 within the first 2 weeks following infection with Mycobacterium bovis. 1,25-D3-positive mononuclear cells were later identified in all tuberculous granulomas by immunohistochemical staining of postmortem lymph node tissue. These results suggest a role for 1,25-D3 both at the onset of infection and in the development of the granuloma in these infected animals. Using a monoclonal antibody to the vitamin D receptor (VDR) as a VDR agonist, we confirmed that activation of the vitamin D pathway profoundly depresses antigen-specific, but not mitogenic, bovine peripheral blood T-cell responses (proliferation and gamma interferon production). Investigation of the mechanism of this suppression showed that the VDR antibody modified the expression of CD80 by accessory cells, such that a significant positive correlation between T-cell proliferation and accessory cell CD80 emerged
