Effects of protease activated receptor (PAR)2 blocking peptide on endothelin-1 levels in kidney tissues in endotoxemic rat mode.

Aims: Septic shock, the severe form of sepsis, is associated with development of progressive damage in multiple organs. Kidney can be injured and its functions altered by activation of coagulation, vasoactive-peptide and inflammatory processes in sepsis. Endothelin (ET)-1, a potent vasoconstrictor, is implicated in the pathogenesis of sepsis and its complications.

Metabolic syndrome among pre- and post-menopausal rural women in Bangladesh: result from a population-based study.

Background: Prevalence of non-communicable diseases are a challenging problems among menopausal women specially in a least developed country like Bangladesh, where majority of women suffering from at least one chronic diseases after menopausal age. So, the main objective of this study was to determine the prevalence of metabolic syndrome and related risk factors in Bangladeshi pre- and post-menopausal women living in the rural setting.

Methods: This study is based on a community based cross-sectional survey among 1802 rural women aged ≥15 years.

The role of angiogenic factors and their soluble receptors in acute lung injury (ALI)/ acute respiratory distress syndrome (ARDS) associated with critical illness.

Background: Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are characterized by a disruption of the endothelium and alveolar epithelial barriers involving increased microvascular permeability, thus resulting in the set of protein-rich pulmonary edema. Angiogenic factors and their receptors, including vascular endothelial growth factor (VEGF)/VEGF-receptor (VEGFR) and the angiopoietin (Ang)/Tie2 signaling pathways, play pivotal roles in both angiogenesis and microvascular permeability. The aim of the study was to assess the relationship between angiogenic factors, their soluble receptors and ALI/ARDS associated with critically ill patients, including sepsis, severe trauma, and post-cardiac arrest syndrome (PCAS).

Disruption of components of vascular endothelial growth factor angiogenic signalling system in metabolic syndrome. Findings from a study conducted in rural Bangladeshi women.

Metabolic syndrome (MetS) is associated with impaired angiogenesis, a process that is chiefly regulated by vascular endothelial growth factor (VEGF) upon binding to its specific receptors, VEGF-R1 and VEGF-R2. The purpose of the present study was to assess trends or patterns in plasma levels of VEGF and its soluble receptors in subjects with (MetS) or without (non-MetS) MetS; and further examine their association with clinical or metabolic parameters using a subpopulation of South Asian country. A total of 1,802 rural Bangladeshi women aged ≥15 years were studied using a population-based cross-sectional survey.

Association of age at menarche with metabolic syndrome and its components in rural Bangladeshi women.

Background: Early age at menarche is associated with increased risk of metabolic syndrome in both China and the West. However, little is known about the impact of age at menarche and metabolic syndrome in South Asian women, including those from low-income country, where age at menarche is also falling. The aim of the present study was to investigate whether age at menarche is inversely associated with metabolic syndrome in Bangladeshi women, who are mostly poor and have limited access to and or poor health care facilities.

Angiogenic factors and their soluble receptors predict organ dysfunction and mortality in post-cardiac arrest syndrome.

Introduction: Post-cardiac arrest syndrome (PCAS) often leads to multiple organ dysfunction syndrome (MODS) with a poor prognosis. Endothelial and leukocyte activation after whole-body ischemia/reperfusion following resuscitation from cardiac arrest is a critical step in endothelial injury and related organ damage. Angiogenic factors, including vascular endothelial growth factor (VEGF) and angiopoietin (Ang), and their receptors play crucial roles in endothelial growth, survival signals, pathological angiogenesis and microvascular permeability.

Using angiogenic factors and their soluble receptors to predict organ dysfunction in patients with disseminated intravascular coagulation associated with severe trauma.

Introduction: Disseminated intravascular coagulation (DIC) is characterized by the concomitant activation of coagulofibrinolytic disorders and systemic inflammation associated with endothelial dysfunction-induced microvascular permeability. Angiogenic factors, including vascular endothelial growth factor (VEGF), angiopoietin (Ang), and their receptors, play crucial roles in angiogenesis and microvascular permeability. The aim of the study was to assess the relationship between angiogenic factors, their soluble receptors and organ dysfunction associated with DIC after severe trauma.

Comprehensive assessment of metabolic syndrome among rural Bangladeshi women.

Background: Metabolic syndrome (MS), defined as a constellation of cardiovascular disease (CVD) risk factors, is one of the fastest growing public health burdens in the Asia-Pacific region. This trend is despite the fact that people in this region are no more overweight than Europeans and Americans. Unfortunately, in South Asia, MS screening has only been performed in a few countries other than Bangladesh.

Prevalence of metabolic syndrome among rural Bangladeshi women.

We assessed prevalence of metabolic syndrome (MS) in rural women of Bangladesh using 1485 women aged ≥15 years. The prevalence rate of MS was 31.25% (NCEP ATP III modified).

Estrogen receptor alpha and beta are both involved in the cerebral VEGF/Akt/NO pathway and cerebral angiogenesis in female mice.

We have previously demonstrated that vascular endothelial growth factor (VEGF) is critical for cerebral angiogenesis in middle-aged female rats and may play a role in the flow-preserving neuroprotective actions of estrogen through its angiogenic and antiapoptotic properties. Here, we attempt to elucidate the effects of estrogen and the specific estrogen receptor (ER) subtype in cerebral VEGF/Akt/NO pathways and cerebral angiogenesis using 15-week old female mice that are either wild-type (WT), lack estrogen receptor α (ERαKO) or β (ERβKO). Protein levels of VEGF and basic signaling molecules of VEGF angiogenic pathway in the frontal cortex were expressed as follows, as revealed by ELISA and immunoblotting : a) VEGF; WT: ERαKO: ERβKO, 47 ± 15: 27 ± 5: 28 ± 5 pg/mg, respectively (P < 0.

VEGF signaling is disrupted in the hearts of mice lacking estrogen receptor alpha.

Estrogen has widely been credited for cardioprotection in women. However, the exact mechanisms that underlie these beneficial estrogenic effects are not completely understood. Here, we sought to: 1) elucidate estrogen's influence on levels of vascular endothelial growth factor (VEGF), a key regulator of cardiovascular processes, and components of its basic signaling machinery (VEGF receptors, Akt, and eNOS) in the heart, and 2) delineate the specific estrogen receptor signaling pathway that mediates its beneficial effects using mice lacking either estrogen receptor alpha or estrogen receptor beta.
