Abstract. Thyroid hormones play an important role in body homeostasis by facilitating metabolism of lipids and glucose, regulating metabolic adaptations, responding to changes in energy intake, and controlling thermogenesis. Proper metabolism and action of these hormones requires the participation of various nutrients. Among them is zinc, whose interaction with thyroid hormones is complex. It is known to regulate both the synthesis and mechanism of action of these hormones. In the present review, we aim to shed light on the regulatory effects of zinc on thyroid hormones. Scientific evidence shows that zinc plays a key role in the metabolism of thyroid hormones, specifically by regulating deiodinases enzymes activity, thyrotropin releasing hormone (TRH) and thyroid stimulating hormone (TSH) synthesis, as well as by modulating the structures of essential transcription factors involved in the synthesis of thyroid hormones. Serum concentrations of zinc also appear to influence the levels of serum T3, T4 and TSH. In addition, studies have shown that Zinc transporters (ZnTs) are present in the hypothalamus, pituitary and thyroid, but their functions remain unknown. Therefore, it is important to further investigate the roles of zinc in regulation of thyroid hormones metabolism, and their importance in the treatment of several diseases associated with thyroid gland dysfunction.

Background: Relatively little is known about the role of protective factors in an Arab population in the presence of suicidal risk factors. Aims: To examine the role of protective factors in a subsample of in large Arab Kindred participants in the presence of suicidal risk factors. Methods: We assessed protective and risk factors in a sample of 64 participants (16 suicidal and 48 nonsuicidal) between 15 and 55 years of age, using a comprehensive structured psychiatric interview, the Composite International Diagnostic Interview (CIDI), self-reported depression, anxiety, hopelessness, impulsivity, hostility, and suicidal behavior in first-degree and second-relatives. We also used the Religiosity Questionnaire and suicide attitude (SUIATT) and multidimensional perceived support scale. Results: Suicidal as opposed to nonsuicidal participants were more likely to have a lifetime history of major depressive disorder (MDD) (68.8% vs. 22.9% χ2 = 11.17, p = .001), an anxiety disorder (87.5% vs. 22.9, χ2 = 21.02, p < .001), or posttraumatic stress disorder (PTSD) (25% vs. 0.0%, Fisher’s, p = .003). Individuals who are otherwise at high risk for suicidality have a much lower risk when they experience higher perceived social support (3.31 ± 1.36 vs. 4.96 ± 1.40, t = 4.10, df = 62, p < .001), and they have the view that suicide is somehow unacceptable (1.83 ± .10 vs. 1.89 ± .07, t = 2.76, df = 60, p = .008). Conclusions: Taken together with other studies, these data suggest that the augmentation of protective factors could play a very important role in the prevention of incidental and recurrent suicidal behavior in Arab populations, where suicidal behavior in increasing rapidly.

Do Extra-Platelet Sources Contribute to the Plasma Level of Thrombospondin?

The Relationship

SummaryThrombospondin, a trimeric glycoprotein contained in the platelet α-granules, has been proposed as a marker of in vivo platelet activation. However, it is also synthesised by a range of other cells. The extraplatelet contribution to plasma levels of thrombospondin was therefore estimated by investigating the relationship between plasma thrombospondin levels and platelet count in samples from profoundly thrombocytopenic patients with marrow hypoplasia, using the platelet-specific α-granule protein β-thromboglobulin as control. Serum concentrations of both proteins were highly correlated with platelet count, but while plasma β-thromboglobulin levels and platelet count also correlated, there was no relationship between the number of platelets and thrombospondin concentrations in plasma. Serial sampling of patients recovering from bone marrow depression indicated that the plasma thrombospondin contributed by platelets is superimposed on a background concentration of at least 50 ng/ml probably derived from a non-platelet source, and plasma thrombospondin levels do not simply reflect platelet release.

Structural Conflict

This article examines the evolving relations between Israel and the indigenous Bedouin Arab population of the southern Beer-Sheba region. It begins with a discussion of theoretical aspects, highlighting a structural conflict embedded in the ‘ethnocratic’ nature of nation-building typical of ‘pure’ settler states, such as Israel. The place of the Bedouin Arab community is then analyzed, focusing on the impact of one of Israel's central policies—the Judaization of territory. The study traces the various legal, planning and economic strategies of Judaizing contested lands in the study area. These have included the nationalization of Arab land, the pervasive establishment of Jewish settlements, the forced urbanization of the Bedouin Arabs, and the denial of basic services to Bedouins who refuse to urbanize. However, the analysis also finds a growing awareness among indigenous Arabs of their being discriminated against on ethnic grounds, and the emergence of effective resistance. In recent years, this has resulted in a deadlock between state authorities and the indigenous peoples. The case of the Bedouin Arabs demonstrates that the ethnocentric settler state is weakening and fragmenting, partially at least, due to its own expansionist land, planning and development policies.

Secret History

In 1948 an official ‘Transfer Committee’ was appointed by the Israeli Cabinet to plan the Palestinian refugees' resettlement in the Arab states. Apart from doing everything possible to reduce the Arab population in Israel, the Transfer Committee sought to amplify and consolidate the demographic transformation of Palestine by: preventing the Palestinian refugees from returning to their homes; the destruction of Arab villages; settlement of Jews in Arab villages and towns; and launching a propaganda campaign to discourage Arab return. One of the Transfer Committee's initiatives was to invite Dr Joseph Schechtman, a right-wing Zionist Revisionist leader and expert on ‘population transfer’, to join its efforts. In 1952 Schechtman published a propagandists work entitled The Arab Refugee Problem. Since then Schechtman would become the single most influential propagator of the Zionist myth of ‘voluntary’ exodus in 1948. This article examines the leading role played by Schechtman in promoting Israeli propaganda and politics of denial. Relying on newly-discovered Israeli archival documents, the article deals with little known and new aspects of the secret history of the post-1948 period.
