Abstract
OBJECTIVE Despite the multiple available treatment modalities, cervical cancer is one of the leading causes of mortality and morbidity among female gynecological cancers. Endoplasmic Reticulum (ER) is an effective organelle in ensuring cell homeostasis and is closely related to the development of cancer. Esculetin is a coumarin derivative that has anticancer, anti-inflammatory, antioxidant, and neuroprotective effects. Esculetin may have an anticancer effect by inducting apoptosis and ER stress. In this study, we evaluate that esculetin has an anti-tumor effect on human cervical cancer-derived (HeLa) cells via ER stress. MATERIALS AND METHODS Esculetin was applied to the HeLa cells, and a viability test was performed using the methyl thiazolyl tetrazolium proliferation (MTT) assay. Expression levels of apoptotic genes and anti-apoptotic genes were determined by real-time polymerase chain reaction. The results were statistically evaluated. RESULTS Analysis of the MTT assay detected that esculetin inhibited HeLa cell viability development. Based on Western blot and quantitative real-time polymerase chain reaction (qPCR) analyses, esculetin destroyed cervical cancer cells via the ER stress pathway. CONCLUSIONS The results showed that esculetin may have a potent antitumoral effect. It can potentially be utilized in the pharmacological therapy of cervical cancer.

Abstract
OBJECTIVES To evaluate belinostat's (PXD101) activity on MCF-7 breast cancer stem cells (CSCs) via Wnt, Notch, and Hedgehog. METHODS This research study was carried out at the Department of Medical Biology, Necmettin Erbakan University, Konya, Turkey, from June 2017 to July 2019. The effect of PXD101 on MCF-7 cell viability was determined by cell proliferation kit (XTT). Following belinostat treatment, CD44+/CD24- MCF-7 CSCs were isolated by FACS. Ribonucleic acid isolation and copy-deoxyribonucleic acid synthesis were carried out using HEK-293 cells, MCF-7 cells, and MCF-7 CSCs. Expression changes of metastasis-related genes, Wnt, Hedgehog, Notch, and stem cell markers were analysed by quantitative polymerase chain reaction. The IC50 in MCF-7 cancer cells was 5 μM for 48 hours. The FACS analysis indicated that 2% of the MCF-7 cancer cells were CSCs. Following belinostat treatment, the MCF-7 cell count decreased by 44%, and the MCF-7 CD44+/CD24- CSC count decreased by 66%. RESULTS Belinostat treatment reduced the expression of metastasis, Wnt, Notch, Hedgehog, and stem cell marker genes. CONCLUSION Belinostat has a potential effect on the differentiation and self-renewal of breast CSCs.

Abstract
The Women's Health Initiative Memory Study reported that older women using conjugated equine estrogens hormone therapy (HT) with or without medroxyprogesterone acetate were at increased risk for probable dementia and smaller brain volumes. These adverse effects were greatest among women who had type 2 diabetes mellitus (T2DM) at baseline or who developed the disease during follow-up. This review summarizes existing literature from randomized trials, observational studies, and preclinical studies to provide a fundamental understanding of the effects of the interaction between T2DM and HT on cognitive and metabolic health changes in brain aging.

Abstract
In addition to the classical motor symptoms, motivational and affective deficits are core impairments of Parkinson's disease (PD). We recently demonstrated, by lesional approaches in rats, that degeneration of the substantia nigra pars compacta (SNc) dopaminergic (DA) neurons is likely to have a crucial role in the development of these neuropsychiatry symptoms. We have also shown that, as in clinical investigations, chronic treatment with levodopa or the DA D2/D3 receptor (D2/D3R) agonist ropinirole specifically reverses these PD-related motivational deficits. The roles of specific DA receptor subtypes in such reversal effects remain, however, unknown. We therefore investigated here the precise involvement of D1, D2 and D3R in the reversal of the motivational and affective deficits related to SNc DA neuronal loss. Three weeks after bilateral and partial 6-hydroxydopamine (6-OHDA) SNc lesions, rats received 14 daily intraperitoneal administrations of the selective D1R agonist SKF-38393 (2.5 or 3.5 mg kg(-1)), the selective D2R agonist sumanirole (0.1 or 0.15 mg kg(-1)), or the preferring D3R gonist PD-128907 (0.1 or 0.15 mg kg(-1)). Anxiety-, depressive-like and motivated behaviors were assessed in an elevated-plus maze, a forced-swim test, and an operant sucrose self-administration procedure, respectively. All DA agonists attenuated anxiety- and depressive-like behaviors. However, only PD-128907 reversed the motivational deficits induced by 6-OHDA SNc lesions. This effect was blocked by a selective D3R (SB-277011A, 10 mg kg(-1)), but not D2R (L-741,626, 1.5 mg kg(-1)), antagonist. These data provide strong evidence for the role of D3R in motivational processes and identify this receptor as a potentially valuable target for the treatment of PD-related neuropsychiatric symptoms.

Abstract
Several factors may be responsible for osteoarthritis after anterior cruciate ligament (ACL) reconstruction. The detrimental effect of the surgical technique may explain part of the progression of the pathologic process. In this study, the effect of ACL reconstruction on articular cartilage was investigated by measuring proteoglycan fragments (PF) in synovial fluid collected from patients who had undergone this operation. Synovial samples were obtained from 44 patients with chronic ACL deficiency aged 26 +/- 7 years preoperatively, and from some of them, samples were collected for monitoring at 1 month (n = 22), 3 months (n = 17), 6 months (n = 18) and 12s month (n = 18). Synovial fluid taken from 12 contralateral asymptomatic knees of 12 patients (not necessarily opposite knees of ACL-deficient cases) served as controls. Preoperative values were significantly larger than controls (P < 0.05). PF level reached its maximum value in the 1st month (P < 0.05) and then gradually decreased. It was significantly lower than preoperative values at 6 and 12 months but still greater than controls (P < 0.05). It seems that surgical trauma affects cartilage metabolism for the first 3 months postoperatively. Although reconstruction of the ACL contributes to articular cartilage homeostasis, a complete return to normal values cannot be achieved in 1st postoperative year at least in knees with chronic ACL deficiency. Long-term monitoring is needed to see whether these findings are early signs of osteoarthritis. Further studies may more clearly demonstrate the effect of the surgical procedure on knees with acute and subacute ACL deficiency.
