Two important classes of manifolds of quantum states, the locally quasi-classical manifold and the quasi-classical manifold, are introduced from the estimation theoretical viewpoint, and they are characterized geometrically by the vanishing conditions of the relative phase factor (RPF), implying the close tie between Uhlmann parallel transport and the quantum estimation theory.

The role of hyperleptinemia in cardiovascular diseases is well known; however, in the renal tissue, the exact site of leptin's action has not been established. This study was conducted to assess the effect of leptin treatment for 7 and 28 days on renal function and morphology and the participation of angiotensin II (Ang II), through its AT1 receptor. Rats were divided into four groups: sham, lo...

The C-terminal Eps 15 Homology Domain proteins (EHD1-4) play important roles in regulating endocytic trafficking. EHD2 is the only family member whose crystal structure has been solved, and it contains an unstructured loop consisting of two proline-phenylalanine (PF) motifs: KPFRKLNPF. In contrast, despite EHD2 having nearly 70% amino acid identity with its paralogs, EHD1, EHD3 and EHD4, the la...

Glomerular immune injury in the rat: The influence of angiotensin II and a-adrenergic inhibitors. Nephron filtration rate (SNGFR) decreases significantly after the administration of large doses of antiglomerular basement membrane antibody (anti-GBM) as a result of reductions in both nephron (renal) plasma flow (RPF) and the glomerular permeability coefficient (LA). We have examined the particip...

Retroperitoneal fibrosis (RPF) is a rare condition of unclear aetiology. It is believed to be immune-related. About two-thirds of cases are thought to be idiopathic.' We present a case of idiopathic RPF in a 37-year old male with recurring abdominal pain over a five-month period associated with features of ischaemic colitis and bilateral hydroceles. An initial CT scan ofthe abdomen showed a sig...

The relaxed physical factorization (RPF) preconditioner is a recent algorithm allowing for the efficient and robust solution to block linear systems arising from three-field displacement-velocity-pressure formulation of coupled poromechanics. For its application, however, it necessary invert blocks with algebraic form C ˆ = ( + ? F T ) , where symmetric positive definite matrix, rank-deficient ...

PURPOSE To study clinical presentation, laboratory results, imaging findings and treatment options and outcomes of retroperitoneal fibrosis (RPF). To determine whether it follows the same natural course and response to treatment in the Asian population as in the Western world. MATERIALS AND METHODS Medical records of patients diagnosed with RPF on imaging and histopathology between February 2...

Under high sodium intake renal dopamine (DA) increases while NOS I expression in macula densa cells (MD) decreases. To explore whether renal DA and NOS I, linked to natriuresis and to the stability of the tubuloglomerular feedback, respectively, act in concert to regulate renal plasma flow (RPF) and glomerular filtration rate (GFR). Male Wistar rats were studied under a normal sodium intake (NS...

We have previously reported that hyperglycemia in healthy human subjects increased the renal vasodilator response to the angiotensin-converting enzyme inhibitor captopril. This observation raised intriguing possibilities relevant to the pathogenesis of nephropathy in patients with diabetes mellitus. To ascertain whether the effect of captopril was indeed mediated by a reduction in angiotensin I...

BACKGROUND Many articles on retroperitoneal fibroses (RPFs), published over the last ten years, seem to set out as innovative the carried-out both diagnostic procedures and therapeutic measures, while a careful examination of the literature identifies them as a sheer application of previous acquisitions. Surely, instead, several interesting advances have been pointed-out in the field of pathoge...
