Background: Monitoring of mycophenolic acid (MPA) levels may be useful for effective mycophenolate mofetil (MMF) dosing. However, whether commonly obtained trough levels are an acceptable method of surveillance remains debatable. We hypothesized that trough levels of MPA would be a poor predictor of area under the curve (AUC) for MPA. Methods: A total of 51 patients with lupus nephritis who were on MMF 1500 mg twice a day and had a 4-h AUC done were included in this study...

Phocoenamicins B and C ( 1 and 2 ), together with the known spirotetronate phocoenamicin ( 3 ), were isolated from cultures of Micromonospora sp. The acetone extract from a culture of this strain, isolated from marine sediments collected in the Canary Islands, displayed activity against methicillin-resistant Staphylococcus aureus (MRSA), Mycobacterium tuberculosis H37Ra and Mycobacterium bovis . Bioassay-guided fractionation of this extract using SP207ss column chromatography and preparative reversed-phased HPLC led to the isolation of the new compounds 1 and 2 belonging to the spirotetronate class of polyketides...

Ammonia plays a central role in the life and death of all living organisms and has been studied for over one hundred years. Ammonia is necessary for growth and development but it is toxic in excess and, as a result, differing methods of ammonia neutralization have evolved. Following physiological and pathological stress to the heart, tissue ammonia levels rise. Local ammonia neutralization may be inadequate and excess ammonia may exert its toxic effects. Phenylbutyrate (PBA), which is FDA approved for the treatment of elevated blood ammonia in urea cycle disorders, provides an accessory pathway for ammonia clearance...

Angiotensin I converting enzyme (ACE) gene is one of the most-studied candidate genes related to essential hypertension (EH). Pulse pressure (PP) may reflect vascular stiffness, especially in patients with EH, and has been used to predict EH. Previous evidence has indicated that obesity is a traditional risk factor of hypertension. The aim of the present study was to investigate the interaction between the obesity status and ACE gene polymorphisms on the development of high level of PP. A total of 1980 adults (1024 hypertensive and 956 normotensive) were included in this study and genotyped for ACE gene polymorphisms...

Introduction Neuropathic pain is a debilitating condition. The importance of neuroimmune interactions in neuropathic pain has been evidenced by the involvement of different immune cells in peripheral and central sensitization of pathological pain. Macrophages and microglia are the most abundant immune cells activated in injured nerves and spinal cord, respectively. Several lines of evidence showed that macrophage/microglia survival, activation, proliferation, and differentiation require the involvement of macrophage-colony stimulating factor...

This study investigated the antioxidant capacity and intestinal bacteria community in a mouse model of DSS-induced colitis. Twenty mice were randomly assigned to two treatments: mice with colitis induced by 5% DSS (DSS group) and mice with colitis induced by 5% DSS that also received melatonin treatment (MEL group). The DSS group showed significantly less antioxidant capability than the MEL group, but the two groups did not differ significantly in terms of diversity index (Shannon and Simpson), bacterial culture abundance (Chao1 and ACE), and coverage (Good's coverage estimator)...

Introduction: Commercial divers, high altitude pilots, and astronauts are exposed to some inherent risk of decompression sickness (DCS), though the mechanisms that trigger are still unclear. It has been previously showed that diving may induce increased levels of serum angiotensin converting enzyme. The renin angiotensin aldosterone system (RAAS) is one of the most important regulators of blood pressure and fluid volume. The purpose of the present study was to control the influence of angiotensin II on the appearance of DCS...

To date, no extensive literature review exists regarding potential uses of mung bean proteins and peptides. As mung bean has long been widely used as a food source, early studies evaluated mung bean nutritional value against the Food and Agriculture Organization of the United Nations (FAO)/the World Health Organization (WHO) amino acids dietary recommendations. The comparison demonstrated mung bean to be a good protein source, except for deficiencies in sulphur-containing amino acids, methionine and cysteine...

BACKGROUND: Angiotensin receptor neprilysin inhibitor (ARNi) enhances beneficial natriuretic peptides by inhibiting their breakdown through neprilysin. Although the first-in-class ARNi sacubitril/valsartan (LCZ696) reduced mortality and morbidity in heart failure (HF) with reduced ejection fraction (EF) compared to angiotensin converting enzyme inhibitor (ACEi), mechanistic data on ARNi are scarce. ARNi may be superior to ACEi in attenuating adverse cardiac remodeling and dysfunction post-myocardial infarction (MI)...

BACKGROUND: Nursing home (NH) administrators need tools to measure the effectiveness of care delivered at the end of life so that they have objective data on which to evaluate current practices, and identify areas of resident care in need of improvement. METHODS: A three-phase mixed methods study was used to develop and test an empirically derived chart audit tool aimed at assessing the care delivered along the entire dying trajectory. RESULTS: The Auditing Care at the End of Life (ACE) instrument contains 27 questions captured across 6 domains, which are indicative of quality end-of-life care for nursing home residents...

A technique for the spatially resolved and molecule-specific detection of chemical vapors is presented. The chemical specificity arises from a transient absorption spectrum where an ultraviolet (UV) pulse excites the molecule to a Rydberg state, and a near-infrared (NIR) or visible probe pulse records a transient absorption spectrum. By recording the NIR pulse reflected off a random, distant object and measuring the elapsed time between the emission of the UV pulse and the absorption of a counter-propagating NIR pulse, the distance to the absorber is obtained...

Renin-angiotensin-aldosterone system (RAAS) and sympathetic nervous system play crucial roles in heart failure with reduced ejection fraction (HFrEF). Clinical trials provide strong evidence of prognostic benefits for combination therapy with angiotensin-converting enzyme inhibitor (ACEI) and β-blocker in the treatment of HFrEF. Angiotensin receptor blocker (ARB) is not superior to ACEI in improving mortality and an alternative for patients who are intolerant to ACEI. Prognostic evidence for triple therapy which combined angiotensin receptor blocker (ARB) and ACEI in addition to β-blocker therapy, is still controversial in HFrEF...

Geranium molle L., commonly known as Dove's-foot Crane's-bill or Dovesfoot Geranium, is an herbaceous plant belonging to the Geraniaceae family. Contrary to many other Geranium species, the bioactivity and the phytochemical composition of G. molle seem not to have attracted attention until a recent study from our group regarding the bioactivity of several aqueous and organic extracts of the plant. In particular, we assessed the cytotoxic activity of these extracts against several human tumor cell lines (breast, lung, cervical and hepatocellular carcinomas) and a non-tumor porcine liver primary cell line, inspired by an ethnopharmacological report describing the traditional use of this medicinal plant in some regions of Northeast Portugal for the treatment of cancer...

BACKGROUND: Hypertension may result from high-fat (HF) diet induced-obesity and overexposure to glucocorticoids in utero. Recent studies demonstrated the potent contribution of adipose tissue's renin-angiotensin system (RAS) to systemic RAS, which plays a key role in regulating blood pressure (BP). In this study, we investigated the effects of prenatal dexamethasone (DEX) exposure and postnatal HF diet on RAS of adipose tissue. METHODS: RAS and BP of 6-month old rats exposed to prenatal DEX and/or postnatal HF diet were examined...
