Objective: To investigate the effects of raloxifene on the insulin sensitivity and lipid profile in insulin-sensitive and insulin-resistant postmenopausal women.
Study Design: This placebo-controlled, double-blind, randomized study involved 64 postmenopausal women aged between 45 and 55 years. All subjects were screened with the insulin resistance homeostasis model assessment (IR-HOMA) and those patients in the lowest quartile (n = 16) were assigned as insulin sensitive and those in the highest quartile as insulin resistant (n = 16). Patients in both groups received either raloxifene hydrochloride (60 mg/day) or a placebo for a period of 12 weeks. Insulin sensitivity, the serum lipid profile and anthropometric measurements were established before and after therapy.
Results: Women with the highest IR-HOMA scores were associated with a significantly higher weight, body mass index, waist and waist-to-hip ratio (p < 0.05). Raloxifene significantly reduced the IR-HOMA scores from 5.76 ± 2.91 to 1.93 ± 0.96 (p = 0.02) and modified the lipid profile in insulin-resistant patients when compared with the placebo group and those patients receiving raloxifene in the insulin-sensitive group.
Conclusion: Raloxifene reduced insulin resistance and modified the lipid profile in insulin-resistant postmenopausal women.

Background: Nippostrongylus brasiliensis-a nematode of rodents-is commonly used as a model to study the immunobiology of parasitic nematodes. It is a member of the Strongylida-a large order of socioeconomically important parasitic nematodes of animals. Lipids are known to play essential roles in nematode biology, influencing cellular membranes, energy storage and/or signalling.

This study investigated the effects of non-thermal atmospheric plasma (NTAP) treatment on the growth, chemical composition, and biological activity of geranium (Pelargonium graveolens L'Herit) leaves. NTAP was applied at a frequency of 13.56 MHz, exposure time of 15 s, discharge temperature of 25 °C, and power levels (T1 = 50, T2 = 80, and T3 = 120 W).

Background: Gestational exposure to non-persistent endocrine-disrupting chemicals (EDCs) may be associated with adverse pregnancy outcomes. While many EDCs affect the endocrine system, their effects on endocrine-related metabolic pathways remain unclear. This study aims to explore the global metabolome changes associated with EDC biomarkers at delivery.

Background: Cardiovascular risk factors (CRFs) like hypertension, high cholesterol, and diabetes mellitus are increasingly linked to cognitive decline and dementia, especially in cerebral small vessel disease (cSVD). White matter hyperintensities (WMH) are closely associated with cognitive impairment, but the mechanisms behind their development remain unclear. Blood-brain barrier (BBB) dysfunction may be a key factor, particularly in cSVD.

Background: Normothermic ex situ heart perfusion (ESHP) has emerged as a valid modality for advanced cardiac allograft preservation and conditioning prior to transplantation though myocardial function declines gradually during ESHP thus limiting its potential for expanding the donor pool. Recently, the utilization of dialysis has been shown to preserve myocardial and coronary vasomotor function. Herein, we sought to determine the changes in myocardial metabolism that could support this improvement.
