In the present investigation, we compared the impact of illness on quality of life (QOL) in adult outpatients with unipolar (N = 89) and bipolar (N = 25) depression. While attending a university hospital in southern Brazil, patients completed the WHO's QOL Instrument-Short Version and the Beck Depression Inventory. After analyses, patients with bipolar depression reported significantly lower sc...

As a natural phenomenon, mania without major depression will of course survive DSM-5 and ICD-11, but following its integration as a diagnosis into bipolar-I disorder (BP-I) in those manuals, BP-I will be more heterogeneous and, paradoxically, will include a unipolar disorder. Furthermore, unipolar mania will no longer be adequately identified and coded as an independent disorder in public healt...

This senior project report describes the process of designing a unipolar inverter. This high low, unipolar inverter utilizes switches in which a pair operates in high frequency while a second pair operates in low frequency. The purpose of this project is to convert a range of high DC voltage and convert it to an AC output voltage of 120 Vrms with a power rating of 100 W. Nonetheless, this parti...

Unipolar leads using Wilson's central terminal as an "indifferent" electrode have been in general clinical use for many years. The central terminal was not introduced as a theoretically correct reference for unipolar leads, but as a convenient reference that was at least better than using one of the limbs alone, as in the old CR, CL, and CF leads, in which the exploring electrode potentials wer...

While numerical bipolar rating scales may evoke positivity bias, little is known about the corresponding bias in verbal scales. The choice of verbalization middle category lead to response particularly if it not line with scale polarity. Unipolar and seven-category which verbalizations categories matched or did match implemented polarity were investigated randomized experiments using a non-prob...

Chloride ion, the majority salt in nature, is ∼52% faster than sodium ion (DNa+ = 1.33, DCl- = 2.03[10(-9)m(2)s(-1)]). Yet, current electrochemical desalination technologies (e.g. electrodialysis) rely on bipolar ion conduction, removing one pair of the cation and the anion simultaneously. Here, we demonstrate that novel ion concentration polarization desalination can enhance salt removal under...

Unipolar depression is moderately heritable. It is unclear whether structural brain changes associated with unipolar depression are present in healthy persons at risk of the disorder. Here we investigated whether a genetic predisposition to unipolar depression is associated with structural brain changes. A priori, hippocampal volume reductions were hypothesized. Using a high-risk study design, ...

PURPOSE To compare outcomes of unipolar versus bipolar uncemented hemiarthroplasty and determine factors affecting outcomes. METHODS 433 and 274 elderly patients with displaced intracapsular femoral neck fractures underwent uncemented unipolar hemiarthroplasty and uncemented bipolar hydroxyapatite-coated hemiarthroplasty, respectively. Surgical options were based on the patient's general cond...

Introduction The mechanisms of J-ST elevation in the right precordial leads in patients with Brugada syndrome (BrS) remain controversial (ie, repolarization vs depolarization hypotheses). Recently, epicardial substrate ablation for late fractionated potentials and a low-voltage area (LVA) in the right ventricular outflow tract (RVOT) has been performed for ventricular fibrillation (VF) that is ...

Neuroimaging studies of mood disorders demonstrate abnormalities in brain regions implicated in reward processing. However, there is a paucity of research investigating how social rewards affect reward circuit activity in these disorders. Here, we evaluated the relationship of both diagnostic category and dimensional depression severity to reward system function in bipolar and unipolar depressi...
