Objective To evaluate effects of physical activity and food consumption on plasma concentrations of free and total transforming growth factor beta-1 (TGF-β1), beta-2 (TGF-β2), and beta-3 (TGF-β3) in individuals with knee osteoarthritis (OA). Methods Participants ( n = 40 in 2 cohorts of 20; mean age 70 years) with radiographic knee OA were admitted overnight for serial blood sampling. Cohorts 1 and 2 assessed the impacts of food intake and activity, respectively, on TGF-β concentrations. Cohort 1 blood draws included 2 hours postprandial the evening of day 1 (T3), fasting before rising on day 2 (T0), nonfasting 1 hour after rising (T1B), and 4 hours after rising (T2). Cohort 2 blood draws included T3, T0, fasting 1 hour after rising and performing activities of daily living (T1A), and nonfasting 2 hours after rising (T1B). By sandwich ELISAs, we quantified plasma free and total TGF-β1 concentrations in all samples, and plasma total TGF-β2 and TGF-β3 in cohort 2. Results Free TGF-β1 represented a small fraction of the total systemic concentration (mean 0.026%). In cohort 2, free and total TGF-β1 and total TGF-β2 concentration significantly increased in fasting samples collected after an hour (T1A) of activities of daily living (free TGF-β1: P = 0.006; total TGF-β1: P < 0.001; total TGF-β2: P = 0.001). Total TGF-β3 increased nonsignificantly following activity ( P = 0.590) and decreased ( P = 0.035) after food consumption while resting (T1B). Conclusions Increased plasma concentrations of TGF-β with physical activity suggests activity should be standardized prior to TGF-β1 analyses.

Abstract Background Nanomedicine contributes to the efficiency of pharmacological treatments and progresses rapidly. The present study was designed to produce exopolysaccharide (BSEPS) from Bacillus subtilis sp. strain reported in our previous study was further characterized, and its BSEPS for synthesis of the nanoparticle Ag-BSEPS using microwave heating to determine the possible effects of a prepared solution containing Ag-BSEPS versus thioacetamide (TAA) evoked liver fibrosis in Wister albino rats. Nanoparticles with silver (Ag) core have been synthesized in an aqueous solution after exposure of BSEPS to periodate oxidation. Animals were split into four groups: I - control rats, water ad libitum for 6 weeks; II - rats were injected with TAA 200 mg/kg-1 3 times/week for 4 weeks IP; III - Ag-BSEPS 100 mg/kg-1 IP twice a week for 6 weeks; and IV - TAA, as group II followed by Ag-BSEPS as group III. The antifibrotic effects of Ag-BSEPS were appraised by determining different hepatotoxicity indices, oxidative stress, and inflammatory and liver fibrosis markers. Results Nanoparticles were obtained with a diameter size range of 50–100 nm characterized by SEM and TEM without using any harmful reagents. Results evinced considerably reduced activity of liver functions such as transaminases (AST, ALT), gamma-glutamyl transferase (GGT), and alkaline phosphatase (ALP) in the group which received TAA followed by Ag-BSEPS compared to the other group which received only TAA. In the current results, the administration of Ag-BSEPS showed an improvement in the proinflammatory cytokines. On the contrary, the antioxidant enzymes in liver homogenates revealed significant improvement (concentration of glutathione peroxidase (GSH-PX), superoxide dismutase (SOD), and catalase (CAT) increases) in animals with TAA-induced liver damage followed by Ag-BSEPS. Moreover, the activities of the fibrotic markers transforming growth factor-beta 1(TGF-β1) and type III pro-collagen (PCIII) were increased in liver tissues in the group which was given TAA alone as compared to the controls. The percentage of fibrosis of hepatic tissue had a positive correlation with the levels of PCIII and TGF-β1, followed by Ag-BSEPS compared to the TAA group without nanocomposite treatment. Microscopic examinations revealed inhibitory effects of Ag-BSEPS on inflammatory changes and deterrent of liver fibrosis. Conclusion It was suggested that the biochemical and histological amelioration observed in Ag-BSEPS (100 mg/kg-1 twice a week for 6 weeks) treated the fibrotic rats.

Background: The healing failure rate after rotator cuff repair is considerably high. Purpose: To evaluate the effect of a porous suture containing transforming growth factor beta 1 (TGF-β1) on the sustained release of TGF-β1 and rotator cuff healing in a rat model. Study Design: Controlled laboratory study. Methods: A porous suture was developed, and its tensile strength was measured. TGF-β1 was delivered using the porous suture, and a TGF-β1 release test and human fibroblast proliferation assay were performed. For the animal experiment, 30 rats were randomly allocated into 3 groups (n = 10 each). A bilateral supraspinatus tendon tear was made in all the rats, and repair was performed. Group 1 received repair only; group 2, repair and a single injection of TGF-β1; and group 3, repair using the porous suture containing TGF-β1. Eight weeks after repair, biomechanical and histological analyses were performed. Results: The porous suture was successfully developed with mechanical properties compatible with the conventional suture, and the sustained release of TGF-β1 from the porous suture was confirmed. In addition, the cell proliferation assay confirmed the biological safety of the porous suture. In the animal experiment, group 3 biomechanically exhibited the largest cross-sectional area and the highest ultimate failure load and ultimate stress (all P < .05). Histological examination revealed that group 3 showed significantly better collagen fiber density and tendon-to-bone maturation than did groups 1 and 2 (all P < .05). Conclusion: The porous suture containing TGF-β1 could sustainedly and safely release TGF-β1, and its use during rotator cuff repair could improve rotator cuff healing, as assessed on the basis of the biomechanical and histological changes in the rat model in this study. Considering the effectiveness, safety, and convenience of the porous suture without extra effort in surgery, the findings of the present study will have a far-reaching effect on the treatment of rotator cuff tears. Clinical Relevance: The porous suture containing TGF-β1 might improve healing after rotator cuff repair.

Abstract Background Iran’s population is aging. Disability is a major public health problem for older adults, not only in Iran but all over the world. The purpose of this study was to investigate the relationship between cardio-metabolic and socio-demographic risk factors and disability in people 60 years and older in Iran. Methods The baseline (cross-sectional) data of 2426 samples from the Bushehr Elderly Health (BEH) program was included in the analysis. The participants were selected through multi-stage random sampling in Bushehr, southern Iran. Socio-demographic characteristics, as well as the history of diabetes and other chronic diseases, and smoking were measured using standardized questionnaires. Anthropometric measurements and laboratory tests were performed under standard conditions. Dependency was determined by the questionnaires of basic activities of daily living (BADL) and instrumental activities of daily living (IADL) using Barthel and Lawton scales respectively. Multiple logistic regression was used in the analysis. Results Mean (Standard Deviation) of the participants’ age was 69.3 (6.4) years (range: 60 and 96 years), and 48.1% of the participants were men. After adjusting for potential confounders, being older, being female (OR (95%CI): 2.3 (1.9–2.9)), having a lower education level, a history of diabetes mellitus (OR: 1.4 (1.2–1.7)) and past smoking (OR: 1.3 (1.0–1.6)), and no physical activity (OR: 1.5 (1.2–1.9)) were significantly associated with dependency in IADL. Also, being older and female (OR: 2.4 (1.9–3.0)), having a lower education level, no physical activity (OR: 2.2 (1.6–2.9)) and daily intake of calories (OR: 0.99 (0.99–0.99)) were associated with dependency in BADL. Conclusion Dependency in older adults can be prevented by increasing community literacy, improving physical activity, preventing and controlling diabetes mellitus, avoiding smoking, and reducing daily calorie intake.

Hepatocellular carcinoma (HCC) is the most common form of liver malignancies worldwide. Alogliptin is an anti-diabetic that may have effective anticancer properties against many types of malignancies. Taxifolin is a flavonoid that has potent antioxidant, and anti-inflammatory properties. The objective of this study was to explore the impact of alogliptin and/or taxifolin on diethyl nitrosamine-induced HCC in rats. One hundred male Wistar rats were divided into five equal groups as follows: Control; HCC; HCC + Alogliptin; HCC + Taxifolin; and HCC + Alogliptin + Taxifolin group. The survival rate, liver function tests, tissue antioxidant enzymes, malondialdehyde (MDA), nuclear factor (erythroid derived 2)-like 2 (Nrf2), transforming growth factor beta 1 (TGF-β1), interleukin 1 alpha (IL-1α), and toll-like receptor 4 (TLR4) were measured. Also, hepatic caspase 3, caspase 9, beclin-1, and c-Jun NH2-terminal kinase (JNK) in addition to serum alpha-fetoprotein (AFP) and α-L-Fucosidase (AFU) were assessed. Specimens of the liver were subjected to histopathological examination. Alogliptin and/or taxifolin induced significant improvement of liver function tests with significant increase in the survival rate, tissue antioxidant enzymes, Nrf2, caspase 3, caspase 9, Beclin-1 and JNK activities associated with significant decrease in serum AFP and AFU, tissue MDA, TGF-β1, IL-1α and TLR4 expression compared to HCC group. These results were significant with taxifolin/alogliptin combination when compared to the use of each of these agents alone. In conclusion, taxifolin/alogliptin combination might be used as adjuvant therapy for attenuation of HCC.

Background Increasing evidence highlights potential associations between varus thrust and health domains associated with knee osteoarthritis (OA). Objective The aim of this study was to investigate the association between varus thrust and 2 subcategories—“pain and stiffness” and “activities of daily living (ADL)”—of the Japanese Knee Osteoarthritis Measure (JKOM). Design This was a cross-sectional study. Methods In total, 296 outpatients with knee OA visiting orthopedic clinics were enrolled. The inclusion criteria were age ≥50 years, medial knee OA and Kellgren-Lawrence (K/L) grade ≥1 in one or both knees, and the ability to walk independently. Standard posterior-anterior knee radiographs were measured for varus alignment. Participants were video recorded while walking and were evaluated for the presence or absence of varus thrust. Pain and stiffness of the knee joint and ADL were evaluated using the JKOM. Multivariate regressions (outcomes: pain and stiffness and ADL; predictor variable: varus thrust) were performed. Results Varus thrust was present in 46 (16.2%) of 284 patients. Multivariate regression analyses demonstrated that varus thrust is independently associated with pain and stiffness, adjusted for age, sex, body mass index, K/L grade, and varus alignment (β=.17, P=.005). However, the association between varus thrust and ADL was not significant (β=.11, P=.058). Based on sensitivity analyses, including participants of K/L grade 1 had little influence on this analysis. Limitations Only 16.2% of participants had a varus thrust. Moreover, a cause-effect relationship between varus thrust and pain and stiffness remains unknown due to the cross-sectional design of this study. Conclusions Varus thrust was associated with pain and stiffness in patients with medial knee OA. However, the association between varus thrust and ADL did not reach significance.

Transforming growth factor beta (TGF-β)1 is thought to be involved in breast carcinogenesis. TGF-β1 acts in an antiproliferative manner in the early stages of breast carcinogenesis, but promotes tumor progression and metastases in the advanced stages of the disease. No data have been published on serum TGF-β1 in breast cancer. We investigated TGF-β1 serum levels in patients with breast cancer (n=135), ductal carcinoma in situ (DCIS) I to III (n=67) or fibroadenoma (n=35), and in healthy women (n=40) to determine its value as a differentiation marker between malignant, pre-invasive and benign diseases and as a predictive marker for metastatic spread. Median (range) TGF-β1 serum levels in patients with breast cancer, DCIS I-III or benign breast lesions and in healthy women were 48.8 (18–82.4) pg/mL, 45.3 (26.9–58.3) pg/mL, 47.2 (17.2–80.5) pg/mL and 51.6 (30.9–65.1) pg/mL, respectively (p=0.2). In breast cancer patients TGF-β1 serum levels showed no statistically significant correlation with tumor stage, lymph node involvement, histological grade, estrogen receptor status and progesterone receptor status. Our data fail to indicate any correlation between serum TGF-β1 levels and clinicopathological parameters of breast diseases. Serum TGF-β1 levels do not provide clinical information in addition to established tumor markers.
