There is evidence that adipocytokines play an important role in metabolism and inflammation. Because human dramatically changes inflammatory bowel disease (IBD) chronic inflammation the hallmark of disease, we studied serum levels leptin, adiponectin, resistin, ghrelin patients with ulcerative colitis (UC) Crohn's (CD) comparison healthy controls (HC).Leptin, active were measured 100 IBD (46 UC 54 CD) 60 matched HC using commercially available enzyme-linked immunosorbent assays. Leptin,...

In this work, the diphenylalanine dipeptide was covalently attached to a tripyridyl porphyrin macrocycle and conveyed self-assembling properties resulting hybrid. This hybrid metallated with non-noble metals, Zn Sn, investigated toward photocatalytic hydrogen evolution. The Sn derivative, SnPy3P-FF, able produce photocatalytically in presence of known cobaloxime catalyst TEOA as sacrificial electron donor. When nanostructures SnPy3P-FF were employed system, enhanced production observed....

Background Tumour necrosis factor α is a critical mediator of inflammation-related altered metabolism in inflammatory bowel disease (IBD), possibly through its interaction with adipokines, which play an important role IBD. Infliximab well established antitumour treatment Aim and methods We studied serum levels leptin, adiponectin resistin 20 IBD patients before after infliximab using commercially available enzyme-linked immunosorbent assays. The results were correlated alterations activity,...

Antibiotics are commonly prescribed in Neonatal Intensive Care Units (NICU), where stewardship interventions challenging. Lowering antibiotic consumption is desperately needed Greece, a country with high resistance rates. We sought to assess the effectiveness of low-cost and -resource intervention reduce use Greek NICUs implementing “low-hanging fruit” approach. A prospective quasi-experimental study was conducted 15/17 public Greece (9/2016–06/2019). The selected discontinuation antibiotics...

Objective . We aimed to investigate the incidence and severity of retinopathy extremely premature infants evaluate risk factors outcome cases. Materials Methods Out 200 births, we retrospectively reviewed 9 cases that developed ROP. excluded where ROP in newborns > 30 weeks gestational age medical notes were unavailable or incomplete. Topical drops cyclopentolate 1% phenylephrine 5% instilled fundoscopy was performed using a direct ophthalmoscope. Results The 4.5% 9-year period. divided...

Pollution of insulators is one the most significant problems that can affect reliability power systems. Several practices have been employed to improve insulation performance under polluted conditions such as extending creepage distance, using specially designed profiles, washing and hydrophobic materials manufacture or coat their surfaces. Depending on pollution type severity well local climatic at site installation, different maintenance procedures against should be employed. In this...

Background The COVID-19 pandemic imposed a great burden on every healthcare sector including primary care. Confident clinical decisions, proactive isolation of suspicious cases, and testing resource allocation are crucial importance at care facilities. criterion standard for the diagnosis COVID-19, multisystem disease with diverse symptoms, is real-time reverse-transcription polymerase chain reaction (rRT-PCR). Objectives We aim to identify demographic predictors positive severe acute...
