OBJECTIVE Glycosides of cistanche (GC) is extracted from Xin Jiang Cistanche, which is widely used as a Chinese herb. This study aims to evaluate the effects of GC on vascular dementia (VD). MATERIALS AND METHODS The VD model was established by the ligature of the bilateral common carotid artery in adult Wistar rats, who received daily i. p. administration of saline, GC (10 mg/kg body weight/...

New Voltage Differencing Differential Input Buffered Amplifier (VD-DIBA) based lossless grounded and floating inductance simulation circuits have been proposed. The proposed grounded simulated inductance circuit employs a single VD-DIBA, one floating resistance and one grounded capacitor. The floating simulated inductance (FI) circuits employ two VD-DIBAs with two passive components (one floati...

BACKGROUND Obstructed defecation syndrome (ODS) occurs in about 7% of adults; it seems that the etiology of pelvic floor disorders is multifactorial. Pregnancy and childbirth damage to the pelvic nerve and muscles are proposed causes for this condition. The precise role of vaginal delivery (VD) is not clearly defined, although in recent studies association of pelvic floor disorder with Operativ...

This investigation examined whether the directional index of neural information flow (NIF) could be employed to characterize the synaptic plasticity in the CA3-CA1 pathway of the hippocampus and assessed which oscillatory rhythm was associated with cognitive impairments induced by vascular dementia (VD). Rats were randomly divided into control and VD groups. The animal model of VD used the two-...

BACKGROUND Respiratory dead-space is often increased in lung disease. This study evaluates the effects of increased alveolar dead-space (Vd(alv)), pulmonary shunt, and abnormal ventilation perfusion ratio (/) distributions on dead-space and alveolar partial pressure of carbon dioxide (Pa(co(2))) calculated by various methods, assesses a recently published non-invasive method (Koulouris method) ...

Hypertension (HTN) is a risk factor for erectile dysfunction, but its effect on vas deferens (VD) contractility and the ejaculatory response has not been delineated. NG-nitro-L-arginine methyl ester (L-NAME), a nitric oxide synthase inhibitor, was used for induction of nitric oxide (NO)-deficient HTN. Our aim was to evaluate the effects of L-NAME-induced HTN on rat VD contractility and to deter...

Objective: Stem cell based therapy has emerged as a promising treatment alternative for stress urinary incontinence (SUI). Human urine-derived stem cells (USCs) have no risk from biopsy and therefore may be a better option than other adult stem cells. Possible therapeutic mechanisms of action of stem cells are homing of cells to areas in need of repair and secretion of bioactive paracrine facto...

The degree to which a person relies on visual stimuli for spatial orientation is termed visual dependency (VD). VD is considered a perceptual trait or cognitive style influenced by psychological factors and mediated by central reweighting of the sensory inputs involved in spatial orientation. VD is often measured with the rod-and-disk test, in which participants align a central rod to the subje...

The molecular mechanisms underlying stress urinary incontinence (SUI) are unclear. We aimed to evaluate the molecular alterations in mice urethras following vaginal trauma and ovariectomy (OVX). Twenty-four virgin female mice were equally distributed into four groups: noninstrumented control; vaginal distension (VD) group; OVX group; and VD + OVX group. Changes in leak point pressures (LPPs), g...

The molecular mechanisms underlying the regulation of vas deferens (VD) motility and semen emission are still poorly understood. We now report evidence on VD expression of phosphodiesterase type 5 (PDE5), which regulates nitric oxide (NO)-induced relaxation and cGMP breakdown in smooth muscle cells. In human VD, the PDE5 abundance was relatively high (>3 x 10(6) molecules/microg total RNA), alt...
