Plantar fibromatosis (PF) is a rare benign disease. CPT-11 purchase Here we report bilateral PF accompanied by Dupuytren's contracture in the right palm. Magnetic resonance imaging was useful in diagnosing PF, although biopsy was needed to rule out hemangioma. As the patient had been receiving female hormone therapy since orchiectomy, there may be a possibility that estrogen accelerated the growth of PF. Local excision with a 1-cm margin was performed, followed by primary wound closure. Neither complication nor recurrence had occurred 6 months after the surgery.

The management of these visceral sarcomas remains controversial, with surgical resection forming the mainstay, being optimally achieved in a unit familiar with the management of sarcomas. These tumours are difficult to diagnose based on history and are challenging to localize on conventional imaging modalities. We report a case of a 61-year-old female who proceeded to emergent laparotomy with imaging suggestive of small bowel ischaemia secondary to portal venous thrombosis. Incidental leiomyosarcoma was noted on histology and was discussed at local multidisciplinary meeting regarding further management. Published by Oxford University Press and JSCR Publishing Ltd.

Side effects of the drug include infections, skin rashes, and allergic reactions. Raynaud's phenomenon (RP), a vasospastic syndrome and an important feature of different connective tissue diseases, is not an expected finding in AS patients. This article reports the development of secukinumab-related RP in a 35-year-old female patient with AS. Treatment with secukinumab was continued and RP was treated with low-dose aspirin and a calcium-channel blocker. © The Author(s), 2020.Background Hashimoto's thyroiditis (HT) is a common autoimmune disorder that causes significant morbidity. Interleukin (IL)-17 was identified as a major contributing factor in the pathogenesis of HT. Blastocystis hominis (BH) is a very common infection and has been shown to be associated with several diseases. Our aim was to determine serum IL-17 level in HT patients with and without BH infection and the effect of eradicating BH in patients with HT. Methods A prospective cohort study was conducted on 20 HT patients not infected with BH (group I), 20 HT patients infected with BH (group II), and 20 healthy patients (group III). Serum free triiodothyronine (FT3), free thyroxine (FT4), thyroid stimulating hormone (TSH), thyroid peroxidase antibodies (anti-TPO), and IL-17 were performed by ELISA method and were repeated in group II after 6 weeks of eradication of BH. Results Patients with HT showed a significantly higher serum IL-17 compared with controls. IL-17 was significantly higher in HT patients infected with BH compared with HT patients not BH infected (mean 6.93 ± 2.83 pg/ml versus 3.25 ± 1.55 pg/ml, p = 0.003). After BH eradication TSH, anti-TPO, and IL-17 were significantly decreased (mean 14.76 ± 11.11 µIU/ml versus 9.39 ± 7.11 µIU/ml, p  less then  0.001; mean 308 ± 175.6 IU/ml versus 295.4 ± 167.1 IU/ml, p = 0.006; and mean 6.93 ± 2.83 pg/ml versus 6.45 ± 2.48 pg/ml, p  less then  0.001), respectively. Multivariate analysis after treating BH infection showed that IL-17 was significantly negatively correlated with FT3 (adjusted p = 0.002) and significantly positively correlated with anti-TPO (adjusted p = 0.045). Conclusion Treatment of BH infection ameliorates HT through reduction in IL-17, anti-TPO, and TSH.

The primary aim of this study was to examine the relationship between OSA and quality of life (QoL) in women with PCOS. Methods We conducted an observational cross-sectional study. PCOS was diagnosed according to the Rotterdam criteria. Women with increased risk of OSA, based on the Berlin questionnaire or the Epworth Sleepiness Scale (ESS), had home-based polysomnography performed (ALICE PDx). Participants were divided into two groups (a) PCOS only women with normal ESS and low-risk Berlin questionnaire (no sleep studies performed), or women with normal sleep studies [oxygen desaturation index (ODI)  less then  5 events/hour]; and (b) PCOS+OSA women with PCOS and OSA ODI ⩾ 5. QoL was assessed using the World Health Organization QoL questionnaire (WHOQOL-BREF) and the PCOS health-related quality of life questionnaire (PCOSQ). Results A total of 39 women were included; age (mean ± SD) was 32.2 ± 8.9 years, weight 92.5 ± 23.7 kg and body mass index (BMI) 34.1 ± 7.9 kg/m2; 38.5% (n = 15) had OSA. Compared with women with PCOS only, women with PCOS+OSA had higher BMI, HbA1c, C-reactive protein and low-density lipoprotein. ODI was independently associated with impaired QoL. Excessive daytime sleepiness (EDS) was independently associated with anxiety, depression and impaired QoL. Conclusions OSA is highly prevalent and is associated with impaired QoL and worse metabolic profile in women with PCOS. Interventional studies are needed to examine the impact of OSA in women with PCOS.

The aim of this study was to test how local adaptation might affect climate-driven range shifts in plants, and if this might differ between plants with different life histories. Simulated range shift dynamics were compared for hypothetical annual, perennial and tree species, each comprised of either one plastic genotype or six locally adapted genotypes. The landscape consists of shifting climate bands made up of 20 × 20 m patches containing multiple individuals. Effects of seed dispersal, breadth of the plastic species' tolerance, steepness of the climate gradient and rate of the climate shift are also examined. Local adaptation increased the equilibrium range size and aided range shifts by boosting fitness near range edges. However, when the rate of climate change was doubled on a steep gradient, locally adapted trees exhibited a higher percent loss of range during the climate shift. The plastic annual species with short dispersal was unable to recover its range size even after the climate stabilized, while the locally adapted annuals tracked climate change well. The results suggest that in most situations local adaptation and longer dispersal distances will be advantageous, though not necessarily sufficient, for tracking suitable climates. However, local adaptation might put species with long generation times at greater risk when climate shifts are very rapid. If confirmed by empirical tests, these results suggest that identifying variation between species in how fitness varies along climate gradients and in these key demographic rates might aid in prioritizing management actions. © The Author(s) 2020.

In this study we assess neutral and adaptive genetic structure and genetic diversity in Brasilianthus carajensis (Melastomataceae), an endemic herb from Amazonian Savannas. Using RAD sequencing we identified a total of 9365 SNPs in 150 individuals collected across the species' entire distribution range. Relying on assumption-free genetic clustering methods and environmental association tests we then compared neutral with adaptive genetic structure. We found three neutral and six adaptive genetic clusters, which could be considered management units (MU) and adaptive units (AU), respectively. Pairwise genetic differentiation (F ST) ranged between 0.024 and 0.048, and even though effective population sizes were below 100, no significant inbreeding was found in any inferred cluster. Nearly 10 % of all analysed sequences contained loci associated with temperature and precipitation, from which only 25 sequences contained annotated proteins, with some of them being very relevant for physiological processes in plants. Our findings provide a detailed insight into genetic diversity, neutral and adaptive genetic structure in a rare endemic herb, which can help guide conservation and management actions to avoid the loss of unique genetic variation. link2 © The Author(s) 2020.

This study explores the mechanisms of the reno-protective effects of Momordica charantia (M. charantia) in diabetic rats following treatment with highly active antiretroviral therapy (HAART) regimen triplavar. Materials and Methods Adult male Sprague-Dawley rats (n=48) were divided into 7 groups (A-G).Treatment groups (B-G) had 7 animals per group and control group (Group A) had 6 animals per group. Diabetes was induced with streptozotocin (STZ) by intraperitoneal injection (STZ 45 mg/kg body weight). The animals were euthanized on the tenth week with kidneys removed for examination and blood obtained via cardiac puncture. Results Key renal parameters showed no albuminuria, normal blood urea nitrogen (BUN), serum creatinine and electrolytes in all groups treated with M. charantia. Untreated diabetic (Group B) and HAART treated diabetic (Group C) showed severe albuminuria, a significantly raised BUN and serum creatinine (P less then 0.05) and gross electrolyte disturbances. link3 Blood glucose levels were consistently and significantly raised in all groups not receiving the adjuvant M. charantia (P less then 0.05). Levels of oxidative stress enzymes Superoxide dismutase (SOD), Catalase and activities of Reduced Gluthaione (GSH) and Malondiadehyde (MDA) were significantly lower in all groups not receiving M. charantia. Histopathology in untreated diabetic and HAART treated animals showed severe degenerative changes in the glomeruli and inflammatory cellular infiltration while M. charantia treated animals showed an essentially normal glomerular appearance with capillary loops and normal cytoarchitecture. Conclusion M. charantia extract administration improved blood glucose levels, reinstates renal function, reduces body weight loss and restores hyperglycemia.Objectives According to recent studies, valproate shows some protection against oxidative stress (OS) induced by neurotoxins. Current investigation tried to determine the possible ameliorating effects of sodium valproate (SV) against aluminum (Al)-induced cell death, apoptosis, mitochondrial membrane potential (MMP), and OS in PC12 cells. Materials and Methods In this in vitro study, PC12 cells were treated with different concentrations of aluminum maltolate (Almal) with and without SV (50-400 µM). Cell viability was assessed by MTT assay. To measure quantitatively the effects of SV on Al-induced apoptosis and reactive oxygen species (ROS), flowcytometry using 7AAD/annexin-V and 2', 7'-dichlorofluorescein diacetate staining were employed, respectively. MMP was monitored using the retention of rhodamine 123. Catalase (CAT) activity was assayed by the rate of decomposition of hydrogen peroxide. Results Exposure of PC12 cells for 48 hr to Almal (125-2000 µM) significantly reduced cell viability (IC50=1090 μM), increased ROS generation and apoptosis, and reduced MMP and CAT activity.
