Moreover, fractal and other methods described here can be used to study the origin and evolution of genomes.
Although tissue-based genomic tests can aid in treatment decision-making for patients with prostate cancer, little is known about their clinical adoption.
To evaluate regional adoption of genomic testing for prostate cancer and understand common trajectories of uptake shared by regions.
This dynamic cohort study of patients diagnosed with prostate cancer used administrative claims from Blue Cross Blue Shield Axis, the largest source of commercial health insurance in the US, to characterize temporal trends in the use of commercial, tissue-based genomic testing and calculate the proportion of tested patients at the hospital referral region (HRR) level. Eligible patients from July 1, 2012, through June 30, 2018, were those aged 40 to 89 years with prostate cancer diagnosed from July 1, 2012, through June 30, 2018.
Group-based trajectory modeling was used to classify regions according to discrete trajectories of adoption of commercial, tissue-based genomic testing for prostate cancer. Across regions with was highly variable in the US at the regional level and may be associated with contextual measures related to socioeconomic status and patterns of prostate cancer care. These findings highlight factors underlying differential adoption of prognostic technologies for patients with cancer.

To evaluate and compare the effects of homologous and heterologous PRP (Platelet-Rich Plasma) on the quality and speed of skin wound healing, compared to Poor Platelet Plasma (PPP).
Twenty-one male adult rabbits were used; two for preparing homologous PRP, with the rest of them separated randomly in three groups, according to the treatment received PPP - control (n=5), homologous PRP (n=7), heterologous (n=7). Excisional skin wounds were made on the back of the animals, for the application of homologous and heterologous PPP and PRP. At the 14th post-operative day (POD), the animals were subjected to a new wound, and the treatments were inverted. The wounds were evaluated macroscopically and histologically.
A larger percentage of scar retraction was observed on the group treated with heterologous PRP, compared to homologous PRP, at the third POD, an increase of 25.03% (p=0.01). No other statistically significant differences among treatments were observed. Among every group, skin healing was efficient, without local adverse effects.
Heterologous PRP contributed with more tissue retraction at the beginning of the wound healing process. After this, there were no differences on the wound healing skin process treated with PRP or PPP. However, our findings suggest the presence of others plasmatic factors, besides platelets, which could also contribute to the wound healing process, and thus, should be further investigated.

The aim of the present study was to explore whether combined calcium and vitamin D supplementation is beneficial for osteoporosis in postmenopausal women.
We searched the PubMed, Cochrane library, Web of science and Embase databases and reference lists of eligible articles up to Feb, 2020. Randomized controlled trials (RCTs) evaluating the effect of combined calcium and vitamin D on osteoporosis in postmenopausal women were included in the present study.
Combined calcium and vitamin D significantly increased total bone mineral density (BMD) (standard mean differences (SMD) = 0.537; 95% confidence interval (CI) 0.227 to 0.847), lumbar spine BMD (SMD = 0.233; 95% CI 0.073 to 0.392; P < 0.001), arms BMD (SMD = 0.464; 95% CI 0.186 to 0.741) and femoral neck BMD (SMD = 0.187; 95% CI 0.010 to 0.364). It also significantly reduced the incidence of hip fracture (RR = 0.864; 95% CI 0.763 to 0.979). Subgroup analysis showed that combined calcium and vitamin D significantly increased femoral neck BMD only when the dose of the vitamin D intake was no more than 400 IU d
(SMD = 0.335; 95% CI 0.113 to 0.558), but not for a dose more than 400 IU d
(SMD = -0.098; 95% CI -0.109 to 0.305), and calcium had no effect on the femoral neck BMD. Subgroup analysis also showed only dairy products fortified with calcium and vitamin D had a significant influence on total BMD (SMD = 0.784; 95% CI 0.322 to 1.247) and lumbar spine BMD (SMD = 0.320; 95% CI 0.146 to 0.494), but not for combined calcium and vitamin D supplement.
Dairy products fortified with calcium and vitamin D have a favorable effect on bone mineral density. Combined calcium and vitamin D supplementation could prevent osteoporosis hip fracture in postmenopausal women.

Thus, the anti-cancer activity of xanthene derivatives has become an important topic in the development of new and potent anti-cancer drug substances. Previously published novel series of xanthen-3-one and xanthen-1,8-dione derivatives have been synthesized in one of our laboratories and showed anti-proliferative activity in HeLa cancer cell lines. This series serves as a good basis to develop quantitative structure-activity relationship (QSAR), to study the relations between anti-proliferative activity and chemical structures. DIRECT RED 80 mouse A QSAR model has been derived that relies only on two-dimensional molecular descriptors, providing mechanistic insight into the anti-proliferative activity of xanthene derivatives. The model is validated internally and externally and additionally with the set of inactive compounds of the original data, confirming model applicability for the design and discovery of novel xanthene derivatives.
