A different way pertaining to punicalagin to ease insulin level of resistance: regulatory belly microbiota along with autophagy.
The concept of drug repurposing and Sildenafil or blue pill are tightly linked over the years. Indeed, in addition to its initial clinical application as an anti-hypertensive drug in the pulmonary system, Sildenafil is also known for its beneficial effects in erectile dysfunction. Moreover, evidence have been accumulated to support its value in anti-cancer therapy either alone or in a combination with other clinically efficient chemotherapy drugs. In this review, we focused on the old and recent in vitro and in vivo studies demonstrating the cellular and molecular rationale for the application of Sildenafil in combination therapy in many various types of cancer. We emphasized on the different molecular targets as well as the different signaling pathways involved in cancer cells. The pro-apoptotic effect of Sildenafil through nitric oxide (NO)/ phosphodiesterase type 5 (PDE5)-dependent manner seems to be one of the most common mechanisms. However, the activation of autophagy as well as the modulation of the anti-tumor immunity constitute the other pathways triggered by Sildenafil. Overall, the studies converged to reveal the complexity of the anti-cancer potential of Sildenafil. Thus, through our review we aimed to present an updated and simplified picture of such repurposing of Sildenafil in the field of oncology.This review outlines the discovery and development of a novel series of 1-[4-2-aminoethoxy)phenylcarbonyl]- 3,5-bis-(benzylidene)-4-piperidones 5-8 as potential drug candidates over the last 15 years in our laboratory. Many of these compounds demonstrate excellent cytotoxic properties and are often more potent than contemporary anticancer drugs. Two highly important features of many of these molecules are first, the greater tumour-selective toxicity and second, the ability of these molecules to act as modulators of multi-drug resistance. The modes of action of some of the potent compounds are by apoptosis induction, generation of reactive oxygen species, activation of certain caspases and affecting mitochondrial functions. These molecules also display promising antimalarial and antimycobacterial properties. In a short term toxicity study, these molecules are well tolerated in mice. Structure-activity relationships, and a drug delivery system along with pharmacokinetic studies and metabolic stability of these compounds have been presented. The positive characteristics associated the series 5-8 warrants their further evaluations as candidate antineoplastic drug candidates.Malaria remains a serious problem in global public health, particularly widespread in South America and in tropical regions of Africa and Asia. Chemotherapy is actually the only way to treat this poverty-related disease, since an effective vaccine is not currently available. However, the onset of resistance to the most common antimalarial drugs sometimes makes the current therapeutic regimen problematic. Therefore, the identification of new targets for a new drug discovery process is an urgent priority. In this context, falcipain-2 and falcipain-3 of P. falciparum represent the key enzymes in the life-cycle of the parasite. Both falcipain-2 and falcipain-3 are involved in hemoglobin hydrolysis, essential pathway to provide free amino acids for the parasite metabolic needs. In addition, falcipain-2 is involved in cleaving ankirin and band 4.1 protein, cytoskeletal elements essential for the stability of red cell membrane. This review article is focused on the most recent and effective inhibitors of falcipain-2 and falcipain-3, with a particular attention to peptide, peptidomimetic or nonpeptide inhibitors which targeted one or both the malarial cysteine proteases, endowed with a consistent activity against P. falciparum.A 24-yo female was admitted for acute renal failure, melanoderma, hyponatremia and hyperkalemia. The clinical suspicion of Addison's disease was confirmed by laboratory test and the appropriate replacement therapy with corticosteroids and fludrocortisone was started. In the mean-time primary hypothyroidism and diabetes mellitus type 1 were disclosed and treated, thus fulfilling a diagnosis of autoimmune polyendocrine syndrome type 2. Eighteen months later she was admitted for right sided heart failure. The work-up allowed to diagnose pulmonary arterial hypertension. RGT-018 Ras inhibitor Here we report the clinical course and discuss the putative link between these two rare diseases.Tetrahydrobipterin (BH4) is a pivotal enzymatic cofactor required for the synthesis of serotonin, dopamine and nitric oxide. BH4 is essential for numerous physiological processes at periphery and central level, such as vascularization, inflammation, glucose homeostasis, regulation of oxidative stress and neurotransmission. BH4 de novo synthesis involves the sequential activation of three enzymes, the major controlling point being GTP cyclohydrolase I (GCH1). Complementary salvage and recycling pathways ensure that BH4 levels are tightly kept within a physiological range in the body. Even if the way of transport of BH4 and its ability to enter the brain after peripheral administration is still controversial, data showed increased levels in the brain after BH4 treatment. Available evidence shows that GCH1 expression and BH4 synthesis are stimulated by immunological factors, notably pro-inflammatory cytokines. Once produced, BH4 can act as antiinflammatory molecule and scavenger of free radicals protecting against oxidative stress. At the same time, BH4 is prone to autoxidation, leading to release of superoxide radicals contributing to inflammatory processes, and to production of BH2, an inactive form of BH4, reducing its bioavailability. Alterations in BH4 levels have been documented in many pathological situations, including Alzheimer's disease, Parkinson's disease and depression, in which increased oxidative stress, inflammation and alterations in monoaminergic function are described. This review aims at providing an update of the knowledge about metabolism and role of BH4 in brain function, from preclinical to clinical studies, addressing some therapeutic implications.
Engagement in the arts may have health benefits for older adults. Most research has focused on music and dance; less is known about the benefits of other arts interventions. The purpose of this study was to examine the effects of visual (ceramics and collage) and literary arts (storytelling and writing) on well-being.

We used mixed methods to examine the effects of a 12-week visual or literary arts intervention on well-being. Adults age 55 and over from four housing sites were assigned to start an intervention immediately (intervention) or wait 12weeks (controls). The study included pre/post-test measures of well-being and focus groups about perceived benefits.

Compared to controls, participants in the ceramics intervention had significant improvements in interest in life and mastery, while no changes were observed after the storytelling intervention. Seven psychosocial benefits were identified .
