The endometrium is an essential component of the female uterus which provides the environment for pregnancy establishment and maintenance. Abnormalities of the endometrium not only lead to difficulties in establishing and maintaining pregnancy but also play a causative role in diseases of endometrial origin including endometriosis and endometrial cancer. Non-coding RNAs are proposed to play a role in regulating the genome in both normal endometrial physiology and pathophysiology. In this review, we first provide a general overview of non-coding RNAs and reproductive physiology of the endometrium. We then discuss the role on non-coding RNAs in normal endometrial physiology and pathophysiology of endometrial infertility. We then conclude with non-coding RNAs in the pathophysiology of endometriosis and endometrial cancer.The hypothalamus-pituitary-thyroid axis is one of several hormone regulatory systems from the hypothalamus to the pituitary and ultimately to the peripheral target organs. The hypothalamus and the pituitary gland are in close anatomical proximity at the base of the brain and extended through the pituitary stalk to the sella turcica. The pituitary stalk allows passage of stimulatory and inhibitory hormones and other signal molecules. The target organs are placed in the periphery and function through stimulation/inhibition by the circulating pituitary hormones. The several hypothalamus-pituitary-target organ axis systems interact in very sophisticated and complicated ways and for many of them the interactive and integrated mechanisms are still not quite clear. The diagnosis of central hypothyroidism is complicated by itself but challenged further by concomitant affection of other hypothalamus-pituitary-hormone axes, the dysfunction of which influences the diagnosis of central hypothyroidism. Treatment of both twer or at least altered à priori likelihood of hypopituitarism than in former obvious clinical patient presentations.Symbiosis is a major evolutionary force, especially at the cellular level. Monocrotaline in vitro Here we discuss several older and new discoveries suggesting that besides mitochondria and plastids, eukaryotic nuclei also have symbiotic origins. We propose an archaea-archaea scenario for the evolutionary origin of the eukaryotic cells. We suggest that two ancient archaea-like cells, one based on the actin cytoskeleton and another one based on the tubulin-centrin cytoskeleton, merged together to form the first nucleated eukaryotic cell. This archaeal endosymbiotic origin of eukaryotic cells and their nuclei explains several features of eukaryotic cells which are incompatible with the currently preferred autogenous scenarios of eukaryogenesis.
Lymphangioleiomyomatosis (LAM) is a rare lung disease found primarily in women of childbearing age, characterized by the formation of air-filled cysts, which may be associated with reductions in lung function. An experimental, regional ultra-high resolution CT scan identified an additional volume of cysts relative to standard chest CT imaging, which consisted primarily of ultra-small cysts.
What is the impact of these ultra-small cysts on the pulmonary function of patients with LAM?
A group of 103 patients with LAM received pulmonary function tests and a CT examination in the same visit. Cyst score, the percentage lung volume occupied by cysts, was measured by using commercial software approved by the US Food and Drug Administration. The association between cyst scores and pulmonary function tests of diffusing capacity of the lungs for carbon monoxide (Dlco) (%predicted), FEV
(%predicted), and FEV
/FVC (%predicted) was assessed with statistical analysis adjusted for demographic variables. The distrib and higher ultra-small cyst fraction.

Symptoms of posttraumatic stress disorder (PTSD) are common in family members of patients who have died in the ICU.
Could a pamphlet describing the role of relatives in the end-of-life decision decrease their risk of developing PTSD-related symptoms?
In this assessor-blinded, randomized controlled trial, 90 relatives of adult patients for whom an end-of-life decision was anticipated were enrolled. Relatives were randomly assigned to receive oral information as well as an information pamphlet explaining that the end-of-life decision is made by physicians (Group 1; n= 45) or oral information alone (Group 2; n= 45). PTSD-related symptoms were blindly assessed at 90days following the patient's death by using the Impact of Event Scale (scores range from 0 [indicating no symptoms] to 75 [indicating severe symptoms]). Anxiety and depression symptoms were assessed by using the Hospital Anxiety and Depression Scale score (range, 0-21 [higher scores indicate worse symptoms]).
On day 90, the number of relatives with PTSD-related symptoms was significantly lower in Group 1 than in Group 2 18 of 45 vs33 of 45 (P= .001). The risk ratio of having PTSD-related symptoms in Group 2 compared with Group 1 was 1.8 (95%CI, 1.2-2.7). The mean Impact of Event Scale and Hospital Anxiety and Depression Scale scores were significantly reduced in Group 1 compared with Group 2 28 ± 10 vs38 ± 14 (P< .001) and 13 ± 5 vs17 ± 8 (P= .023), respectively.
An information pamphlet describing the relatives' role during end-of-life decisions significantly reduced their risk of developing PTSD-related symptoms.

Adults born preterm are at a higher risk of cardiopulmonary disease and premature death. Preterm birth is associated with abnormalities in right ventricular (RV) structure and function, but the impact of bronchopulmonary dysplasia (BPD), a common complication of extremely preterm birth, on these parameters remains unknown.
Are preterm birth and BPD associated with alterations in RV structure and function in early adulthood?
Echocardiographic and spirometry data were obtained from the Health of Adults Born Preterm Investigation (HAPI). RV structure and performance were evaluated by using echocardiography, and respiratory function was assessed by using spirometry.
The study comprised 86 young adults born preterm before 30weeks of gestation, including 28 with moderate to severe BPD, and 85 adults of the same age born full term. Individuals were assessed at a mean age of 23 years. RV systolic function was altered in the preterm group, with lower tricuspid annular plane systolic excursion and lower RVs' and RV outflow tract velocity time integral values, especially in those born preterm with BPD.
