Physiological ageing due to the passing of time and prolonged exposure harmful sun rays generate wrinkles reduce skin elasticity. These visible clinical signs can be prevented or reversed by known strategies, such as daily use cosmetic products with antioxidant combinations retinoids. A new dermocosmetic formulation enriched a complex retinoids, called RETINOIDS SERUM, was investigated through ...

We sought to use splice-switching antisense oligonucleotides to produce a model of accelerated ageing by enhancing expression of progerin, translated from a mis-spliced lamin A gene (LMNA) transcript in human myogenic cells. The progerin transcript (LMNA Δ150) lacks the last 150 bases of exon 11, and is translated into a truncated protein associated with the severe premature ageing disease, Hut...

Osteoporosis is a highly prevalent skeletal disorder in the elderly that causes serious bone fractures. Peak bone mass achieved at adolescence has been shown to predict bone mass and osteoporosis related risk fracture later in life. Resveratrol, a natural polyphenol compound, may have the potential to promote bone formation and reduce bone resorption. However, it is unclear whether it can aid b...

background: aging has a growing trend in the world. the elderly experience a high incidence of hospitalization and coronary bypass surgery compared with other age groups, and pain is the most common complaint in these patients. this research was conducted to compare the effect of acupressure and cryotherapy on the pain of removing drain tube from the chest of the elderly who have undergone open...

due to their widespread availability, sandstones are commonly used as a natural stone for buildings, monuments and sculptures. in thecurrent study, nine sandstone samples from the upper red formation (specified by the letters a, b, c, cg, s, s1, sh, tr and min)were studied from a petrophysical point of view and their durability was evaluated. then, their suitability as building stones wasassess...

background sleep apnea (sa) is a common sleep disorder among us adults. associations of sa with alcohol consumption and some chronic diseases have been inconsistent. objectives this study aimed to estimate prevalence of sa and examine its associations with potential factors including alcohol consumption, asthma, diabetes, and hypertension. patients and methods this was a cross-sectional study o...

We incorporate the generic hierarchical architecture of foodwebs into a “unified” model that describes both “micro” and “macro” evolutions within a single theoretical framework. This model describes the “micro”-evolution in detail by accounting for the birth, ageing and natural death of individual organisms as well as prey-predator interactions on a hierarchical dynamic food web. It also provid...

In this experiment, wheat plants were exposed to drought stress during seed development then we worked on the obtained seeds. The seed mitochondrial ultra-structure, and antioxidant enzymes in seedling were investigated after exposure to seed accelerated ageing. Drought stress during seed development induced some changes in mitochondrial ultra-structure. Encountering seed development to drought...

fifty-four specimens of the kingsoldier bream, argyrops spinifer (forsskal, 1775) from coastal waters of the persian gulf, in bushehr province, were aged by otolith readings to assess the suitability of using otolith length/weight for age estimation in this fish. otolith length and weight increased along with an increase in length and age of the fish. the relationship between fish length (tl) a...

Transformer liquid dielectrics evolved where mineral oil has been the dominant choice until emergence of synthetic esters and natural esters. Natural ester-based oils have under extensive investigations to enhance their properties for replacing petroleum-based oil, which is non-biodegradable poor dielectric properties. This paper focuses on exposition ester application in mixed transformer diel...
