Effects of soy isoflavones on endothelial function in healthy postmenopausal women.

2005

Objective: To evaluate the effects of soy isoflavone administration on endothelial function in healthy postmenopausal women. Design: Sixty naturally postmenopausal women were randomly assigned to receive isoflavone or placebo tablets for 6 months. Endothelium-dependent vasodilatation was measured by brachial reactivity technique along with levels of plasma soluble intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), E-selectin, P-selectin and soluble thrombomodulin, von Willebrand factor, and tissue plasminogen activator. Differences between endothelium-dependent and endothelium-independent vasodilatation were assessed by evaluating brachial reactivity par…

Bilateral buccal space lipoma: A rare case presentation

2019

Background The lipoma of the oral cavity is a relatively rare pathology, characterized by overgrowth of the mature adipocytes. Buccal fat pad lipomas usually interfere with the esthetics and the function of the face. Case Report A sixteen-year-old patient reported slow-growing swelling, which started two years ago. Clinical examination revealed two bilateral masses in the soft tissue. MRI imaging revealed a characteristic image of bilateral lipomas connected to the buccal fat pad. Surgical removal was conducted and the histology report confirmed our clinical diagnosis of common lipoma. Discussion The lipoma of the buccal fat pad is a benign neoplasm of the adipose tissue. It should be remov…

Direct oral anticoagulant use in patients with thrombophilia, antiphospholipid syndrome or venous thrombosis of unusual sites: A narrative review.

2018

Direct oral anticoagulants (DOACs) are indicated in the treatment and prevention of venous thromboembolism (VTE). However, the use of DOACs in unusual VTE, including cerebral venous thrombosis (CVT) and splanchnic venous thrombosis (SVT), and in patients with biological thrombophilia including minor thrombophilia (Factor V Leiden and prothrombin G20210A), major innate thrombophilia (protein C and S deficiency, and antithrombin) and major acquired thrombophilia (antiphospholipid syndrome [APS]), remains controversial due to the paucity of available data. There are some reports of DOACs use in the initial treatment or long-term maintenance of patients with either CVT or SVT, but their efficac…

Metabolic syndrome therapy: Prevention of vascular injury by antidiabetic agents

2005

More than 65 million Americans are currently obese. Type 2 diabetes mellitus, frequently seen in obese subjects, affects 17 million adults in the United States, with a continuous and alarmingly increasing rate. To prevent development of diabetes in those who are at high risk, it is recommended to optimize meal planning and enhance physical activity to make sustained weight reduction possible. In addition to lifestyle changes, various oral antidiabetic agents are available, with diverse mechanisms of action. Some target defective insulin secretion (sulphonylureas, benzoic acid derivatives) or glucose absorption (glycosidase inhibitors), whereas others target insulin resistance (metformin, th…

Choosing an ideal pharmacotherapeutic strategy for dyslipidemia in children.

2018

Dyslipdiemia can manifest at a young age, and it is a risk factor for atherosclerotic cardiovascular disease (ASCVD), the principal cause of mortality in developed nations. Therefore, treating it a...

Adrenergic modulation of astroglial phospholipase D activity and cell proliferation.

1999

As phospholipase D (PLD) activation has been associated with mitogenic signalling in several cell types, we tested an association between adrenergic activation of PLD and cellular proliferation in primary cultures of rat cortical astrocytes. In 2-week old cultures, PLD activation by noradrenaline (EC50: 0.49 microM) was inhibited by prazosin, a specific antagonist at alpha1-adrenergic receptors (IC50: 0.23 microM). Adrenergic PLD activation was not affected by genistein, an inhibitor of tyrosine kinases, or by Ro 31-8220, an inhibitor of protein kinase C (PKC), but was dose-dependently depressed in the presence of brefeldin A (1-100 microg/ml), an inhibitor of ARF activation. In experiments…

Glutamatergic activation of hippocampal phospholipase D: postnatal fading and receptor desensitization.

2002

Abstract: Phospholipase D (PLD) activity was determined in rat hippocampal slices between postnatal days 3 and 35. After birth, basal PLD activity was low and, within 2 weeks, increased to reach a plateau that was maintained up to the adult age. Likewise the response to glutamate developed postnatally to reach a maximum at day 8, but then faded rapidly and was almost absent at day 35. Activation of PLD by 4β-phorbol 12β,13α-dibutyrate (PDB) was independent of age, whereas the effect of aluminum fluoride (AlF4−) increased to a plateau within the first week. At day 8, PLD stimulation by glutamate via metabotropic receptors involved protein kinase C activation, but was independent of Ca2+ infl…

The metabolism and availability of essential fatty acids in animal and human tissues.

1994

Essential fatty acids (EFA), which are not synthesized in animal and human tissues, belong to the n-6 and n-3 families of polyunsaturated fatty acids (PUFA), derived from linoleic acid (LA, 18:2n-6) and alpha-linolenic acid (LNA, 18:3n-3). Optimal requirements are 3-6% of ingested energy for LA and 0.5-1% for LNA in adults. Requirements in LNA are higher in development. Dietary sources of LA and LNA are principally plants, while arachidonic acid (AA, 20:4n-6) is found in products from terrestrian animals, and eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are found in products from marine animals. EFA are principally present in dietary triacylglycerols, which should be hydrolyze…

Age-related changes in the endocannabinoid system in the mouse hippocampus.

2015

Previous studies have demonstrated that the endocannabinoid system significantly influences the progression of brain ageing, and the hippocampus is one of the brain regions most vulnerable to ageing and neurodegeneration. We have further examined age-related changes in the hippocampal endocannabinoid system by measuring the levels of anandamide (AEA) and 2-arachidonoylglycerol (2-AG) in young and old mice from two different mouse strains. We found a decrease in 2-AG but not AEA levels in aged mice. In order to identify the cause for 2-AG level changes, we investigated the levels of several enzymes that contribute to synthesis and degradation of 2-AG in the hippocampus. We found a selective …
