The current study suggests artificial groundwater recharge for the development and utilization of groundwater resources through small scale tanks/reservoirs or ponds in the areas where direct rain recharge occurs.Objectives Multiple reasons for suboptimal treatment of breakthrough cancer pain (BTcP) have been reported in the literature. We aimed to ascertain the perception of physicians on the potential inappropriate use and prescription of rapid-onset opioids (ROOs) for breakthrough cancer pain (BTcP) and the causes thereof.Methods Observational study based on an online survey addressed to doctors from different specialties (radiation oncology, medical oncology, anesthesia, palliative care and general practitioners) with experience in the management of BTcP in the Spanish public health setting.Results A total of 114 eligible specialists mainly from radiation oncology (37.7%), medical oncology (24.6%) and pain units (18.4%) participated in the study. Most agreed on important aspects of BTcP management, such as their preference for ROOs or the need for early follow-up after treatment initiation. However, their answers revealed a lack of standardization of BTcP diagnosis. Half of respondents believed that their BTcP patients might misuse ROOs. Physicians polled believed that lack of training in pain management (71.9%) and inadequate BTcP diagnosis and evaluation (66.7%) were the greatest obstacles for prescribing opioids. Specialists also thought that they do not provide the necessary information to patients (51.8%) and caregivers (57.9%) to guarantee the correct use of these drugs.Conclusions These results are of utmost importance as they highlight the need to increase physicians' awareness of BTcP and its management and the need to improve communication with patients and their caregivers. Our findings also indicate the need for future research on the possible misuse of opioids in BTcP patients and its causes.Bone marrow-derived mesenchymal stem cells (BMSCs) from livestock are valuable resources for veterinary therapeutics and animal reproduction. Previous studies have shown that hypoxic conditions were beneficial in maintaining the mesenchymal feature of BMSCs. However, the effects of hypoxia on buffalo BMSCs (bBMSCs) remain unclear. In this study, the effects of hypoxic conditions on cell morphology, migration, polarity, and karyotype of bBMSCs were examined. CPT-11 The results showed that hypoxia (5% oxygen) enhanced colony formation and stress fiber synthesis of bBMSCs. Under the hypoxic culture conditions, the migration capacity and normal karyotype rate of bBMSCs were significantly improved (p less then 0.05), which resulted in weakened cell polarity and enhanced karyotype stability in bBMSCs. In addition, it was significantly (p less then 0.05) upregulated in the expression levels of HIF-TWIST signaling pathway axis-related genes (Hif-1, Hif-2, Twist, Snail, Slug, Fn1, N-cadherin, Collal). The HIF-TWIST axis of bBMSCs was also activated in hypoxia. Finally, it was more effective and easier to maintain the mesenchymal feature of bBMSCs in hypoxic conditions. These findings not only provide theoretical guidance to elucidate the detailed regulation mechanism of hypoxia on mesenchymal nature maintenance of bBMSCs, but also provide positive support to further establish the stable in vitro culture system of bBMSCs.Many cancer cells share the property of carrying out markedly elevated rates of glycolysis to generate energy even in the presence of sufficient oxygen, and this is known as the Warburg effect. In recent years, there has been a resurgence of interest in the Warburg effect, as the field of oncology has amassed evidence that cellular metabolism may play a prominent role in many neoplasms. Largely in the past decade, another prominent and perhaps surprising factor has emerged in the cancer literature the catecholamine molecules, epinephrine (adrenaline) and norepinephrine (noradrenaline), appear to play a role in tumorigenesis and metastasis. The drug propranolol, which blocks beta adrenergic receptors, may be therapeutic in human angiosarcoma, melanoma, and ovarian cancer. The current paper synthesizes these older and more recent findings, in an attempt to unify the major factors that contribute to tumorigenesis. This paper suggests that in addition to the direct interaction of catecholamine signaling with genetic risk factors (including mutagenesis), it interacts with environmental factors such as hypertension, obesity, unhealthy dietary components, physical inactivity, substance abuse, and mental or emotional stress, to promote the Warburg effect by facilitating glucose availability through suppression of pancreatic insulin release. Further, it proposes that many cancer cells synthesize and release catecholamines to activate their own receptors in an autocrine fashion. In summary, catecholamines are an important "new" factor in cancer that may interface with both genetics and environmental factors to alter the Warburg effect and modulate tumorigenesis.Nasopharyngeal cancer (NPC) is a type of head and neck cancer with a high rate of metastasis. Circular RNAs (circRNAs) were reported to be related to the development of human cancers. This research aimed to investigate the functional mechanism of circRNA circ_0000615 in NPC. The gene expression was examined by quantitative real-time polymerase chain reaction (qRT-PCR) or western blot. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay was employed to assess cell proliferation ability. Transwell assay was used to measure cell migratory and invasive abilities. Furthermore, the interaction between miR-338-3p and circ_0000615 or fibroblast growth factor 2 (FGF2) was predicted by starBase v.2.0 and then confirmed by the dual-luciferase reporter assay. Besides, the mouse xenograft experiment was carried out to explore the effect of circ_0000615 on tumor growth in vivo. We detected increased levels of circ_0000615 and FGF2, along with the decreased level of miR-338-3p NPC tissues and cells. Circ_0000615 knockdown suppressed the proliferation, migration, invasion, and EMT of NPC cells. Interestingly, circ_0000615 interacted with miR-338-3p, and miR-338-3p targeted FGF2. Circ_0000615 inhibited miR-338-3p expression to upregulate FGF2 level. Furthermore, both miR-338-3p depletion and FGF2 overexpression weakened the effect of circ_0000615 knockdown on NPC cell progression. Besides, circ_0000615 knockdown repressed tumor growth in vivo. In conclusion, our findings demonstrated that circ_0000615 knockdown suppressed the growth of NPC cells via modulating miR-338-3p/FGF2 axis, providing a theoretical basis for the treatment of NPC.
