Abstract
Stem cell senescence causes different complications. In addition to the aging phenomenon, stem cell senescence has been investigated in various concepts such as cancer, adverse drug effects, and as a limiting factor in cell therapy. This manuscript examines protective medicines and supplements which are capable of hindering stem cell senescence. We searched the databases such as EMBASE, PubMed, and Web of Science with the keywords “stem cell,” “progenitor cell,” “satellite,” “senescence” and excluded the keywords “cancer,” “tumor,” “malignancy” and “carcinoma” until June 2020. Among these results, we chose 47 relevant studies. Our investigation indicates that most of these studies examined endothelial progenitor cells, hematopoietic stem cells, mesenchymal stem cells, adipose-derived stem cells, and a few others were about less-discussed types of stem cells such as cardiac stem cells, myeloblasts, and induced pluripotent stem cells. From another aspect, 17β-Estradiol, melatonin, metformin, rapamycin, coenzyme Q10, N-acetyl cysteine, and vitamin C were the most studied agents, while the main protective mechanism was through telomerase activity enhancement or oxidative damage ablation. Although many of these studies are in vitro, they are still worthwhile. Stem cell senescence in the in vitro expansion stage is an essential concern in clinical procedures of cell therapy. Moreover, in vitro studies are the first step for further in vivo and clinical studies. It is noteworthy to mention the fact that these protective agents have been used in the clinical setting for various purposes for a long time. Given that, we only need to examine their systemic anti-senescence effects and effective dosages.

Roddick CM, Christie CD, Madden KM, Chen FS. Social integration after moving to a new city predicts lower systolic blood pressure. Psychophysiology 2021; 58:e13924.

Abstract
Residential mobility is linked to higher incidence of cardiovascular disease (CVD) and mortality. A mechanism by which residential relocation may impact health is through the disruption of social networks. To examine whether moving to a new city is associated with increased CVD risk and whether the extent to which movers rebuild their social network after relocating predicts improved CVD risk and psychosocial well-being, recent movers (n = 26), and age- and sex-matched nonmovers (n = 20) were followed over 3 months. Blood pressure, C-reactive protein/albumin ratio (CRP/ALB), social network size, and psychosocial well-being were measured at intake (within 6 weeks of residential relocation for movers) and 3 months later. Multiple regression indicated higher systolic blood pressure (SBP) for movers (M = 107.42, SD = 11.39), compared with nonmovers (M = 102.37, SD = 10.03) at intake, though this trend was not statistically significant. As predicted, increases in movers' social network size over 3 months predicted decreases in SBP, even after controlling for age, sex, and waist-to-hip ratio, b = -2.04 mmHg, 95% CI [-3.35, -.73]. Associations between increases in movers' social ties and decreases in depressive symptoms and stress were in the predicted direction but did not meet the traditional cutoff for statistical significance. Residential relocation and movers' social network size were not associated with CRP/ALB in this healthy sample. This study provides preliminary evidence for increased SBP among recent movers; furthermore, it suggests that this elevation in CVD risk may decrease as individuals successfully rebuild their social network.

Abstract
Women's health and sex differences research remain understudied. In 2016, to address the topic of sex differences, the Center for Women' s Health Research (CWHR) at the University of Colorado (cwhr@ucdenver.edu) held its inaugural National Conference, "Sex Differences Across the Lifespan: A Focus on Metabolism" and published a report summarizing the presentations. Two years later, in 2018, CWHR organized the 2nd National Conference. The research presentations and discussions from the 2018 conference also addressed sex differences across the lifespan with a focus on cardiometabolism and expanded the focus by including circadian physiology and effects of sleep on cardiometabolic health. Over 100 participants, including basic scientists, clinicians, policymakers, advocacy group leaders, and federal agency leadership participated. The meeting proceedings reveal that although exciting advances in the area of sex differences have taken place, significant questions and gaps remain about women's health and sex differences in critical areas of health. Identifying these gaps and the subsequent research that will result may lead to important breakthroughs.

Abstract
Background The Clinical features of vascular Behcet’s disease (BD) are not well understood because there are few studies. Our study aimed to investigate characteristics of vascular BD in both genders in different age groups. Results We enrolled 923 patients with BD who presented to our hospital with adequate medical histories and proper vascular screening exams. The raw incidence rate of vascular BD was 17.98% (166/923). The ratio of vascular BD in male to female patients was 1.868 (p = 0.0004, 95% confidence interval (CI): 1.317 to 2.625). There was a tendency towards higher ESR and CRP in vascular BD patients than in mucocutaneous, but the difference was not significant. The most susceptible affected vessels were cerebral (29.6% in males, 59.4% in females) and lower limb vessels (31.2% in males, and 17.2% in females). The incidence of vascular involvement in younger (< 50 years old) and older (≥ 50 years old) patients were similar, with ratios of 16.58% (122/736) and 23.53% (44/187) respectively. However, in females, younger patients were less likely to have vascular involvement than were older patients (11.43% vs. 20% p = 0.0328, OR: 0.5161, 95% CI: 0.2874 to 0.912). Aneurysm or pseudoaneurysm was diagnosed in 1.84% (17/923) patients, mostly in male patients (p < 0.05, OR: 3.221, 95% CI: 1.097 to 9.112). Twenty vascular BD patients were followed up, and the age at BD diagnosis was 33.23 ± 11.56 year. This did not differ statistically with their age at vascular involvement (36.15 ± 9.52 years). Ages of vascular BD patients did not differ significantly from those of mucocutaneous BD patients (n = 143) in both males and females. Conclusion Vascular BD, including lethal types of aneurysm is more likely to occur in male patients. The female patients has a similar incidence rate with the males in their postmenopausal age. There was no evidence of progression course from mucocutaneous BD to vascular involvement.

Abstract
BACKGROUND We examined the role of menopause on cardiac dimensions and function and assessed the efficacy of exercise training before and after menopause. METHODS AND RESULTS Two groups of healthy premenopausal (n=36, 49.4±0.3 years) and postmenopausal (n=37, 53.5±0.5 years) women with no history of cardiovascular disease and with a mean age difference between groups of only 4 years were studied. Cardiac dimensions and systolic and diastolic function were determined by transthoracic echocardiography with tissue Doppler imaging and 2-dimensional speckle tracking. Measurements were performed at baseline and after a 12-week period of high-intensity aerobic cycle training. LV internal diastolic diameter and LV mass were similar in the 2 groups at baseline and increased by ≈2% to 8% (P=0.04-0.0007) with training in both groups. Left atrial end-diastolic and end-systolic volumes were similar for both groups and increased by 23% to 36% (P=0.0006-0.0001) with training. Systolic function assessed by mean global strain was similar in both groups at baseline and increased by ≈8% (P=0.0004) with training in the postmenopausal group. LV displacement increased by ≈3% (P=0.04) in the premenopausal women only. Diastolic function assessed by E/A ratio was similar at baseline and increased by ≈7% (P=0.01) in the premenopausal group and 11% (P=0.0001) in the postmenopausal group with training. CONCLUSIONS These results suggest that training-induced cardiac adaptations are preserved in the early postmenopausal phase. Furthermore, the hormonal changes associated with the menopausal transition do not appear to affect cardiac dimensions and function. CLINICAL TRIAL REGISTRATION URL: http://www.clinicaltrials.gov.

Abstract
Subtle alterations in coagulation and fibrinolysis have been recently reported in patients with endometriosis supporting a potential hypercoagulable status associated with the disease. This cross-sectional study aimed at evaluating some variables of coagulation status and inflammatory markers in women with endometriosis. A total of 314 women who underwent surgery were considered. The case group (n = 169) included patients with a surgical diagnosis of endometriosis, at any stage of disease. The control group (n = 145) included women with a surgical diagnosis of benign gynecologic pathology. No difference was found for thrombin time, International Normalized Ratio (INR), platelet count, neutrophil count, lymphocyte count, neutrophil-to-lymphocyte ratio, and platelet-to-lymphocyte ratio (PLR) between women with endometriosis and controls. Conversely, patients with endometriosis had significantly shortened activated partial thromboplastin time (APTT) when compared to controls (1.08 ± 0.06 and 1.12 ± 0.19, respectively; P < .01). In the subgroup analysis, women with ovarian endometriosis had significantly shortened APTT values in comparison to women without this form and women with stage I to II endometriosis had significantly shorter APTT values and higher PLR than those with stage III to IV disease. In multivariate logistic regression analysis, after controlling for potential confounders, a shortened APTT remained associated with the disease. Activated partial thromboplastin time is shorter in women with endometriosis but still in the normal range. The evidence is insufficient to foresee a possible use of APTT as a diagnostic marker and to claim a crucial role of a systemic hypercoagulable state in the origin of the disease. A role of the local coagulation system in the pathogenesis of the disease cannot be excluded.

Sex differences in micro- and macro-vascular complications of diabetes mellitus. Clin Sci (Lond) 2017; 131:833-846.

Abstract
Vascular complications are a leading cause of morbidity and mortality in both men and women with type 1 (T1DM) or type 2 (T2DM) diabetes mellitus, however the prevalence, progression and pathophysiology of both microvascular (nephropathy, neuropathy and retinopathy) and macrovascular [coronary heart disease (CHD), myocardial infarction, peripheral arterial disease (PAD) and stroke] disease are different in the two sexes. In general, men appear to be at a higher risk for diabetic microvascular complications, while the consequences of macrovascular complications may be greater in women. Interestingly, in the absence of diabetes, women have a far lower risk of either micro- or macro-vascular disease compared with men for much of their lifespan. Thus, the presence of diabetes confers greater risk for vascular complications in women compared with men and some of the potential reasons, including contribution of sex hormones and sex-specific risk factors are discussed in this review. There is a growing body of evidence that sex hormones play an important role in the regulation of cardiovascular function. While estrogens are generally considered to be cardioprotective and androgens detrimental to cardiovascular health, recent findings challenge these assumptions and demonstrate diversity and complexity of sex hormone action on target tissues, especially in the setting of diabetes. While some progress has been made toward understanding the underlying mechanisms of sex differences in the pathophysiology of diabetic vascular complications, many questions and controversies remain. Future research leading to understanding of these mechanisms may contribute to personalized- and sex-specific treatment for diabetic micro- and macro-vascular disease.

Abstract
Leptin is secreted predominantly by adipocytes and exerts its role mainly by interaction with the long form of leptin receptor (LEPR_V2). It has been identified that LEPR_V2 is widely distributed in various tissues, including the anterior pituitary. Cross-talk between leptin and estrogens has been indentified. Estrogen is known to modulate the tissue-specific expression of LEPR_V2 and leptin in ovariectomized (OVX) rats, a model of postmenopausal condition. Our previous data showed that 17β-estradiol (E2) up-regulated the expression of LEPR_V2 protein and mRNA in rat dorsal root ganglion (DRG) in an estrogen receptor alpha (ERα)-dependent manner. But it is still unclear whether estrogen can regulate leptin signalling in the pituitary of OVX rats. In the present study, we found that ovariectomy decreased the expressions of LEPR_V2. Administration of E2 increased the expressions of LEPR_V2 in a dose-dependent manner. In addition, E2 improved LEPR_V2, STAT3, and SOCS3 protein levels in OVX rats. The effects of exogenous E2 were attenuated by ICI 182,780, a specific estrogen receptors antagonist. However, E2 did not change the Lepr_v1, a type of short form of leptin receptor (LEPR), or leptin mRNA levels. Thus, E2 plays a crucial role in regulating pituitary sensitivity to leptin in OVX rats. Our findings implied that exogenous E2 had potential roles in modification of the function of pituitary in postmenopausal women.
