Diabetes (one of non-communicable diseases) is serious due to its complications, such like, cardiovascular ailments, neuropathy, nephropathy, retinopathy, wound gangrene and sexual impotence. Diabetes and associated chronic conditions are rapidly emerging as major health problems. In clinical, there were different drugs for diabetes treatment on different mechanisms. However, there were limited studies on the efficacy of electric stimulations on diabetes therapeutic application. In current study, we try to evaluate the effect of microcurrent electrical nerve stimulator (MENS) on diabetes modulation as an alternative medicine...

Thymol is a phenolic compound that affects physiology in different cell models. However, whether thymol affects Ca²⁺ homeostasis in prostate cancer cells is unknown. The action of this compound on cytosolic Ca²⁺ concentrations ([Ca²⁺]i) and viability in PC3 human prostate cancer cells was explored. The results show that thymol at concentrations of 100-1500 μM caused [Ca²⁺]i rises in a concentration-dependent manner. Removal of extracellular Ca²⁺ reduced thymol’s effect by approximately 80%...

Kainic acid (KA) is a well-known excitatory neurotoxic substance. In the present study, effects of KA-injected intraperitoneally (i.p.), intracerebroventricularly (i.c.v.) or intrathecally (i.t.) on the blood glucose level were investigated in ICR mice. We found that KA administered intraperitoneally (i.p.), intracerebroventricularly (i.c.v.) or intrathecally (i.t.) increased the blood glucose and corticosterone levels, suggesting that KA-induced hyperglycemia appeared to be due to increased blood corticosterone level...

Sodium nitroprusside (SNP) is an antihypertensive drug with proven dose-dependent toxic effects attributed mainly to the production of cyanide but also excesive nitric oxide (NO) and derived reactive species. The present study evaluated whether melatonin administration would have time-dependent protective effect against SNP−induced toxicity. Male Swiss mice were used in this study. Control mice were treated with 0.9% NaCl; the second group was injected with 10 mg melatonin (MEL)/kg body weight (b.w.); the third group was given SNP at the dose of 3,6 mg/kg b...

Despite mechanical ventilation being a very important life-saving intervention, ventilator-induced lung injury (VILI) is related with inflammatory effects and causes high mortality. Our previous study demonstrated that the interleukin-33 (IL-33) cytokine pathway is a biomarker of VILI. The purpose of this study was to further explore the effects of hydrocortisone sodium succinate (HC) on pro-inflammatory IL-33 activation by VILI. The rats were intubated and received ventilation at 20 cmH₂O of inspiratory pressure (PC20) by a G5 ventilator for 4 h as a control group, and an intervention group received the same inspiratory pressure as well as treated with HC at 1 mg/kg at the third hour of ventilation (PC20+HC)...

NPC15199 is a synthesized compound that inhibits inflammation in some models. However, whether NPC15199 affects Ca²⁺ homeostasis in human gastric cancer is unclear. This study examined the effect of NPC15199 on cytosolic free Ca²⁺ concentrations ([Ca²⁺]i) and viability in SCM1 human gastric cancer cells. The Ca²⁺-sensitive fluorescent dye fura-2 was used to measure [Ca²⁺]i. NPC15199 evoked [Ca²⁺]i rises concentration-dependently. The response was reduced by removing extracellular Ca²⁺. NPC15199-evoked Ca²⁺ entry was not inhibited by store-operated channel inhibitors (nifedipine, econazole and SKF96365) and protein kinase C (PKC) activator (phorbol 12-myristate 13 acetate, PMA), or PKC inhibitor (GF109203X)...

There is little knowledge regarding the force production capacities of tug-of-war athletes, who undergo years of high-load strength training on handgrip muscles. The purpose of this investigation was to determine the force-grading strategies of tug-of-war athletes by examining force fluctuation properties at high exertion levels. Sixteen tug-of-war athletes and sixteen sedentary non-athletes performed sinusoidal handgrip grip at 50%-100% of maximal effort at 0.5 Hz under visual guidance. Force outputs of the designate task were recorded with a strain gauge...

Breast cancer is a hormone-related carcinoma and the most commonly diagnosed malignancy in women. Although Her-2, estrogen receptor (ER), and progesterone receptor (PR) are the major diagnostic markers and therapeutic targets to breast cancer, searching for additional molecular targets remains an important issue and one of the candidates is androgen receptor (AR). AR has been shown expressed in 70% breast cancer patients and connects to low recurrence and high survival rate. Our previous study demonstrates that Ser81 phosphorylation of AR in prostate cancer cells is critical for its protein stability modulated by human epidermal growth factor receptor-2 (Her2)...

Neonatal pain and stress induce long-term changes in pain sensitivity. Therefore their interrelation is a topical subject of clinical and basic research. The present study investigated the effects of inflammatory peripheral pain and stress of maternal deprivation (MD)-isolation in 1-2- and 7-8-day-old Wistar rats (P1,2 and P7,8 respectively, ages comparable to preterm and full-term human babies) on basal pain and pain sensitivity in conditions of inflammatory pain (formalin test) during adolescence. The neonatal impacts were: pain (formalin injection, FOR in the paw), stress (a short 60-min MD), or pain+stress combination (FOR+MD), and appropriate controls...

Several retinal degenerative diseases cause vision loss and retinal cell death. Currently, people face prolonged exposure to digital screens, rendering vision protection from light exposure a critical topic. In this study, we designed a complex lutein formula (CLF) by combining several natural compounds: Calendula officinalis, Lycium barbarum, Vaccinium myrtillus, Cassia obtusifolia, and Rhodiola rosea. In addition, we evaluated the protective effects of the formula on retinal functions in an animal model for light-induced retinal degeneration...

Botulinum toxin type A (BTX-A) selectively cleaves synaptosomal-associated protein of 25 kDa (SNAP-25) and results in inhibition of the fusion of synaptic vesicles containing neurotransmitters with the presynaptic membrane to undergo exocytosis and release. The aim of this study was to investigate whether BTX-A inhibited the pyloric smooth muscle contractility induced by acetylcholine (ACh) after BTX-A-mediated cleavage of SNAP-25 antagonized by toosendanin (TSN). Three groups of rat pyloric muscle strips were studied in vitro...

The incidence of osteoporosis has increased among the elderly population. Establishing a model of bone remodeling for screening new drugs is critical to identify safe and effective treatments for osteoporosis. In this study, we established a platform to investigate the therapeutic effects of collagenous peptides extracted from scales of two kinds of fish, namely, sparidae and chanos. These peptides were prepared using seven concentrations of collagenous peptide: 100, 80, 60, 40, 20, 10 and 1 mg/ml. Experimental results indicated that collagenous peptides promoted the proliferation of osteoblasts and inhibited the proliferation of mature osteoclasts; the effective concentration of collagenous peptide-sparidae was 10 mg/ml and that of collagenous peptide-chanos was 40 mg/ml...
