Various skin parameters such as the thickness of the epidermal echo, dermis and subcutaneous tissue, the surface area of individual layers, the thickness of the subepidermal layer with a low echogenic effect, the caliber of blood vessels, as well as the presence or absence of blood flow in the vessels, can be investigated with ultrasound. The aim of our investigation was to evaluate age-related changes and pathological lesions of the face skin using ultrasound examination of the different anatomical areas of the face in young and older women.

GalynaViktorovnaKhrushch plastic surgeon, maxillofacial surgeon, international candidat ASPS, Periorbital area is worthily considered as one of the most complicated regions in terms of correction of the age-related changes using injection techniques of medical aesthetics. According to the classification of I.I. Kolgunenko Russian (1974), tired morph type of age-related changes which is the most physiological type of aging, incorporates changes mainly focused in the middle third of the face, including in the periorbital area. These changes include the formation of grooves (tear trough, palpebromalar groove, nasojugal groove) (Figure 1), dark under-eye circles, mimic wrinkles formation, fat compartment displacement, change in mimic muscle tone, stretching of ligamentous structures, overhang of the upper eyelid.

Rapid-onset vasodilation (ROV) in response to a single muscle contraction is attenuated with aging. Moreover, sex-related differences in muscle blood flow and vasodilation during dynamic exercise have been observed in young and older adults. The purpose of the present study was to explore if sex-related differences in ROV exist in young (n=36, 25±1 yr) and older (n=32, 66±1 yr) adults. Subjects performed single forearm contractions at 10%, 20%, and 40% maximal voluntary contraction. Brachial artery blood velocity and diameter were measured with Doppler ultrasound, and forearm vascular conductance (ml·min-1·100 mmHg-1) was calculated from blood flow (ml·min-1) and mean arterial pressure (mmHg) and used as a measure of ROV. Peak ROV was attenuated in women across all relative intensities in the young and older groups (P<0.05). In a subset of subjects with similar absolute workloads (~5 kg and ~11kg), age-related differences in ROV were observed among both women and men (P<0.05). However, only older women demonstrated an attenuated peak ROV compared to men (91±6 vs. 121±11 ml·min-1·100 mmHg-1, P<0.05), a difference not observed in the young group (134±8 vs. 154±11 ml·min-1·100 mmHg-1, P=0.15). Additionally, examining the slope of peak ROV across contraction intensities indicated a blunted response in older women compared to their young counterparts (P<0.05), with no differences observed between older and young men (P=0.38). Our data suggest that sex-related differences in the rapid vasodilatory response to single muscle contractions exist in older but not young adults, such that older women have a blunted response compared to older men.

Age Related Changes

Aging significantly affects reflex cardiovascular (CV) responses to induced muscular contraction in anesthetized dogs. To further investigate whether age-related changes in alpha-adrenergic-mediated responses to muscular contraction contribute to these previously reported age-related changes in CV responses associated with advanced age, hemodynamic and regional blood flow (BF) responses at baseline and during hindlimb contraction (HLC) were evaluated both before and after alpha-blockade (alpha-AB) in older (8-14 yr old) and in younger (2-3 yr old) beagles during alpha-chloralose anesthesia. alpha-AB with phentolamine resulted in significant (P < 0.05) reductions in mean arterial pressure before and during HLC, regardless of age. However, age-related differences in the systemic vascular resistance, cardiac output, and stroke volume responses to HLC, observed before alpha-AB, were eliminated after phentolamine as the result of an age-related difference in each of these responses to alpha-AB. Baseline BF (microspheres) was unchanged after alpha-AB in seven of eight abdominal organs, regardless of age. However, reductions in BF during HLC were attenuated in seven of eight abdominal organs in the younger dogs after alpha-AB, but in none of these organs in the older dogs, indicative of diminished alpha-mediated vasoconstriction in these organs in the older dogs during HLC. Furthermore, the age-related difference in the combined BF reduction to all eight abdominal organs before alpha-AB was eliminated after alpha-AB. Finally, BF increases to two of four contracting muscles, as well as the combined increase in blood flow to all four contracting muscles, were attenuated after alpha-AB, regardless of age. These results demonstrate that alpha-blockade eliminates many of the age-related differences in CV responses to HLC observed before alpha-AB and suggest that alpha-adrenergic-mediated responses to HLC change with age in beagles.

Abstract Introduction The advances in research methods used in ophthalmology allow for an increasingly accurate examination of the eyes, as well as the morphology and function of the vessels. Colour Doppler imaging is still the first-line method for the analysis of parameters of retrobulbar circulation. Therefore, the aim of this work was to present the current state of knowledge about anatomical and functional age-related changes in retrobulbar arteries. Methods A literature search was performed mainly based on the PubMed database. Results The anatomy of retrobulbar arteries, histological background of age-related vascular changes, age-related changes in retrobulbar blood flow in the ophthalmic artery, central retinal artery, short posterior ciliary arteries, and the reference values for the age-dependent retrobulbar circulation parameters measured by colour Doppler imaging are discussed in this review. Conclusion The age of the subject should always be taken into account when interpreting the parameters of retrobulbar blood flow measured by colour Doppler imaging.

Age Related Changes

Aging is associated with a decline in bone mass, muscle mass, strength, and physical function, and women are more likely to suffer from these physical changes than men. The model presented in this paper illustrates the age related changes in anabolic hormones and how this may partly explain the diminished physical function of older women. The model can also be used to identify potential sites of intervention that could delay the atrophy of the musculoskeletal system. Various pharmacological hormone therapies have been shown to be beneficial, but there may be health risks associated with their use. There is evidence that regular physical activity is related to higher levels of anabolic hormones in older persons, therefore exercise could be an alternative to drugs for slowing the age related changes in the endocrine system. However, some research suggests that the hormone response to exercise is blunted in older women. This lower hormonal response may not be a consequence of aging per se but instead may result from secondary characteristics of aging such as a decline in physical fitness and exercise intensity or changes in body composition. Further research is needed to determine whether exercise-induced increases in endogenous hormones have clinical significance in improving muscle or bone mass in aging women.
