Abstract:

Background: Thyroid function disorder is a common feature in depression, with mixed type of response. Some cases are associated with hyperthyroidism and most commonly hypothyroidism. Unipolar and bipolar depressions are also related differently in consideration to thyroid status. This study comprises of assessment of the thyroid disorder prevalence in depressive patients and comparative analysis among unipolar and bipolar groups.Methods: Study consisted of 161 unipolar and 160 bipolar cases of depression as diagnosed by ICD 10 criteria supported by MINI.

Abstract:

Various areas of social adjustment were compared using the Social Adjustment Scale in 27 remitted bipolars, 24 remitted unipolars and 25 normal controls matched for age and sex. Scores for global adjustment and for social and leisure activities were significantly worse in patients than in controls. The maladjustment in social and leisure activities appeared only in ‘contact with friends' for bipolar patients and ‘diminished social interactions' for unipolar patients. Unipolar patients differed significantly from controls on the items investigating sexual adjustment. In unipolars, social maladj

Abstract:

SynopsisThe blood counts of 80 patients with depression were examined (50 unipolar, 30 bipolar). Many had reduced numbers of circulating lymphocytes. This abnormality was more common in the unipolar group (52%) than in the bipolar group (27%). When those patients with an abnormal dexamethasone suppression test response in both groups were compared, the relative and absolute lymphocyte counts were significantly lower in unipolars. Although cortisol hypersecretion may reduce lymphocyte numbers it is not yet clear whether the findings can be satisfactorily explained in this way.

Abstract:

The United States has been at war for thirteen of the twenty-two years since the Cold War ended and the world became unipolar. Still, the consensual view among international relations theorists is that unipolarity is peaceful. They base this view on two assumptions: first, the unipole will guarantee the global status quo and, second, no state will balance against it. Both assumptions are problematic. First, the unipole may disengage from a particular region, thus removing constraints on regional conflicts. Second, if the unipole remains engaged in the world, those minor powers that decide not

Abstract:

Unipolarity is a novel condition in world politics, and its effects on international alliances have yet to receive sustained theoretical attention. Tracing its impact requires a careful distinction between the purely structural features common to any unipolar system and the unique characteristics of the current unipole (the United States) or the policies undertaken by particular U.S. leaders (such as George W. Bush). In general, the unipole will enjoy greater freedom of action and be less dependent on allied support, enabling it to rely more readily on ad hoc “coalitions of the willing.” Lesse

Abstract:

Despite preponderant power, unipoles often do not get their way. Why? Scholars interested in polarity and the systemic structures determined by the distribution of power have largely focused on material power alone, but the structure of world politics is as much social as it is material. In this article the author explores three social mechanisms that limit unipolar power and shape its possible uses. The first involves legitimation. To exercise power effectively, unipoles must legitimate it and in the act of legitimating their power, it must be diffused since legitimation lies in the hands of

Bipolar disorder cases have increased compared to a decade ago. It is thought that this increase is the result of a high number of bipolar patients who were not recognized early on because bipolar and unipolar depression is difficult to distinguish from one another. In addition, this problem also gave rise to the hypothesis that unipolar depression could develop into bipolar disorder. Therefore, the diagnosis conversion of unipolar depresion into bipolar disorder and its predictor needs to be studied further.

Obtaining unipolar half-cycle optical pulses of femto- and attosecond duration with a large electrical area is an urgent but difficult task.

In this work, it is shown that in a resonant medium a few-cycle pulse can be converted into two unipolar pulses separated in time by a distance that is an order of magnitude or more longer than the duration of the initial pulse.

This paper presents unipolar pulse width modulation technique with sinusoidal sampling pulse width modulation are analyzed for three-phase five-level, seven-level, nine-level and eleven-level cascaded multi-level inverter. The unipolar PWM method offers a good opportunity for the realization of the Three-phase inverter control, it is better to use the unipolar PWM method with single carrier wave compared to two reference waves. In such case the motor harmonic losses will be considerably lower.The necessary calculations for generation of unipolar pulse width modulation strategies have presented

Abstract:

SummaryDifferentiating bipolar from recurrent unipolar depression is a major clinical challenge. In 18 healthy females and 36 females in a depressive episode – 18 with bipolar disorder type I, 18 with recurrent unipolar depression – we applied pattern recognition analysis using subdivisions of anterior cingulate cortex (ACC) blood flow at rest, measured with arterial spin labelling. Subgenual ACC blood flow classified unipolar v. bipolar depression with 81% accuracy (83% sensitivity, 78% specificity).

Abstract:

Background: Changes in olfactory recognition memory may constitute sensory markers in depression. Significant differences may exist between unipolar and bipolar depression. Our study compares olfactory memory between control, unipolar, and bipolar patients in depressed and euthymic states in order to identify potential markers of depression. Methods: 176 participants were recruited in 5 groups: depressed bipolar (DB), euthymic bipolar (EB), depressed unipolar (DU), euthymic unipolar (EU), and controls (HC). The participants had a standardized clinical and olfactory assessment (olfactory memory

Abstract:

This study analyzes and calculates unipolar and bipolar coded configurations of spectral-amplitude-coding optical division multiple access (SAC-OCDMA) systems by using analytic and simulated methods. The important feature of the SAC-OCDMA systems is that multiple access interference (MAI) can be eliminated by code sequences of a fixed in-phase cross-correlation value. This property can be effectively canceled by multiple access interference by using balance detection schemes. This study uses Walsh-Hadamard codes as signature codes for the unipolar and bipolar schemes. The coder and decoder str

Abstract:

A pivotal concept in the field of mood disorders is the dichotomy between unipolar depression and bipolar disorder. Due to the unique treatment in older age bipolar disorder and the scarcity of research in this area, it is clinically important to raise the awareness of the diagnostic conversion of unipolar depression to bipolar disorder in the elderly population. We present a case of a 71-year-old Chinese man whose diagnosis was revised to bipolar disorder after 9 years of treatment for unipolar depression. Organic workup, including blood tests and brain imaging, was performed to rule out orga

Abstract:

ABSTRACT Unipolar localization of IcsA on the surface of Shigella flexneri is required for efficient formation of actin tails and protrusions in infected eucaryotic cells. Lipopolysaccharide (LPS) mutations have been demonstrated to affect either the establishment or the maintenance of IcsA in a unipolar location, although the mechanism is unknown. In order to analyze the contribution of virulence plasmid determinants on the unipolar localization of IcsA, we examined the localization of IcsA expressed from a cloned plasmid copy in two different genetic backgrounds. The localization of IcsA was

This publication takes a mathematical approach to a general solution to the Navier-Stokes equations. The basic idea is a ‎mathematical analysis of the unipolar induction according to Faraday with the help of the vector analysis. The vector analysis ‎enables the unipolar induction and the Navier-Stokes equations to be related physically and mathematically since both ‎formulations are mathematically equivalent. Since the unipolar induction has proven itself in practice, it can be used as a ‎reference for describing the Navier-Stokes equations‎.
