Healthy aging depends on a complex gene-environment network that is ultimately reflected in the expression of different proteins. We aimed to perform a comparative analysis of the plasma proteome of healthy centenarians (n=9, 5 women, age range 100-103 years) with a notably preserved ambulatory capacity (as a paradigm of 'successful' aging), and control individuals who died from a major age-related disease before the expected life expectancy (n=9, 5 women, age range 67-81 years), and while having impaired ambulatory capacity (as a paradigm of 'unsuccessful' aging). We found that the expression of 49 proteins and 86 pathways differed between the two groups. Overall, healthy centenarians presented with distinct expression of proteins/pathways that reflect a healthy immune function, including a lower pro-inflammatory status (less 'inflammaging' and autoimmunity) and a preserved humoral immune response (increased B cell-mediated immune response). Compared with controls, healthy centenarians also presented with a higher expression of proteins involved in angiogenesis and related to enhanced intercellular junctions, as well as a lower expression of proteins involved in cardiovascular abnormalities. The identification of these proteins/pathways might provide new insights into the biological mechanisms underlying the paradigm of healthy aging.Discriminating between those with and without subjective cognitive decline (SCD) in cross-sectional investigations using neuropsychological tests is challenging. The available magnetoencephalographic (MEG) studies have demonstrated altered alpha-band spectral power and functional connectivity in those with SCD. However, whether the functional connectivity in other frequencies and brain networks, particularly the default mode network (DMN), exhibits abnormalities in SCD remains poorly understood. We recruited 26 healthy controls (HC) without SCD and 27 individuals with SCD to perform resting-state MEG recordings. The power of each frequency band and functional connectivity within the DMN were compared between these two groups. Posterior cingulate cortex (PCC)-based connectivity was also used to test its diagnostic accuracy as a predictor of SCD. There were no significant between-group differences of spectral power in the regional nodes. However, compared with HC, those with SCD demonstrated increased delta-band and gamma-band functional connectivity within the DMN. Moreover, node strength in the PCC exhibited a good discrimination ability at both delta and gamma frequencies. Our data suggest that the node strength of delta and gamma frequencies in the PCC may be a good neurophysiological marker in the discrimination of individuals with SCD from those without SCD.BACKGROUND Currently available smartphones are equipped with optic systems allowing even 10x magnifi-ca-tion, which makes it possible to use them as magnifying devices for microsurgery training. The objective of this study was to assess the usefulness of smartphones for basic microsurgery training. MATERIAL AND METHODS Two students began experimental microsurgical training using a smartphone as a magni-fy-ing device. Both students had acquired microsurgical skills following training under the microscope. For the expe-riment, the time of completion of a "6 stitches" test was measured and compared for each student using a smartphone and a microscope, after 1 and 6 hours of training using only a smartphone. RESULTS After one hour of training, the first student completed the "6 stitches" test within 752 min. under the mi-croscope and within 1635 min. using a smartphone, while the respective scores of the second student were 1231 and 2012 min.. In both cases the time required to complete the test was longer when working with a smartphone. The test was repeated after 6 hours of practice with a telephone, and the results now were as follows first student 710 min. with the microscope and 1250 min. with a smartphone, second student 854 min. with the microscope and 1201 min. with a smartphone. CONCLUSIONS 1. The microsurgical skills of both trainees improved gradually when they were using a smartphone (by 38 min. and 81 min) and the microscope (by 04 min. and 38 min). 2. Two drawbacks of the smartphone were noticed lack of three-dimensional vision, deteriorating vertical orientation in the operating field and worse vision quality compared to the microscope. 3. Advantages of this tool include the availability of training at home, low cost and possibility of analysis of images recorded in the smartphone memory.BACKGROUND To investigate the effects of hyperbaric oxygen (HBO) and pentoxifylline (PTX) treatment on osteotendinous junction healing of Achilles tendon in an animal model. MATERIALS AND METHODS Thirty-six adult female Wistar-albino rats were randomly divided into three groups as control, PTX and HBO groups with a total of 12 rats per group. Under general anesthesia, the Achilles tendons were cut at the level of the osteotendinous junction and repaired. After the surgery, no treatment was given to the control group. Fifty mg/kg intraperitoneal PTX was administered to the PTX group daily for 1 week. The HBO group was exposed to 2,5 atmospheric pressure, 100% oxygen for 2 hours daily for 1 week. All animals were sacrificed at the end of sixth week. Biomechanical tests and histological examinations were performed. RESULTS Energy absorption was significantly higher in the PTX group than that in the control group after biomechanical tests (p=0.010). Histopathological evaluation results revealed no difference between the groups however, hyalinization level was relatively better in the HBO group than that in the control group (p=0.026). selleck compound CONCLUSIONS 1. We concluded that PTX has a positive effect on the treatment of osteotendinous junction injuries based on our results. 2. Although HBO therapy did not provide statistically significant differences, it might have some positive effects on these injuries. 3. Further experimental studies and clinical trials should be conducted.BACKGROUND To compare the effectiveness of three techniques of collagen injection in the treatment of low back pain (LBP) in lumbar spondylosis. MATERIAL AND METHODS In this randomized prospective study, 30 patients with lumbar spondylosis were assigned to 3 groups subcutaneous (Group A, n = 10), periradicular (Group B, n = 10) and epidural (Group C, n = 10). Collagen injections were administered once a week (4 injections in total). Assessment involved a visual pain scale (VAS) (0-10), Oswestry scale (0-50), Laitinen scale (0-16) and One Leg Stance Test (OLST) - time to onset of pain in the support limb. Patients were assessed at the start of treatment (W0), on completion of treatment (W1) and 1 month after completion of treatment (W2). RESULTS Improvement was seen with all three techniques of collagen administration. The minimal clinically important difference (MID) of 3 points on the VAS scale was noted in 44% of patients in Group A, 40% of patients in Group B and 60% of Group C. The MID for the Oswestry scale, determined at 10 points, was achieved in 56%, 50% and 20% of patients, respectively, while the MID for the Laitinen scale, determined at 4 points, was achieved in 56%, 30% and 40% of patients, respectively.
