BACKGROUND: Acne has a prevalence of 90% among adolescents. Facial scarring affects 75% of patients. Autologous platelet-rich plasma (PRP) is a novel treatment option for acne scar management and can be used as an adjuvant to acne scar revision procedures. Owing to its remodeling properties, PRP when used as an adjuvant reduces the total number of sittings. OBJECTIVE: To compare efficacy of autologous PRP and subcision against subcision alone in acne scars. METHODOLOGY: It was an experimental analytical study conducted over a period of 2 years...

p15PAF is an oncogenic intrinsically disordered protein that regulates DNA replication and lesion bypass by interacting with the human sliding clamp PCNA. In the absence of DNA, p15PAF traverses the PCNA ring via an extended PIP-box that contacts the sliding surface. Here, we probed the atomic-scale structure of p15PAF-PCNA-DNA ternary complexes. Crystallography and MD simulations show that, when p15PAF occupies two subunits of the PCNA homotrimer, DNA within the ring channel binds the unoccupied subunit. The structure of PCNA-bound p15PAF in the absence and presence of DNA is invariant, and solution NMR confirms that DNA does not displace p15PAF from the ring wall...

DEAD-box proteins are an essential class of enzymes involved in all stages of RNA metabolism. The study of DEAD-box proteins is challenging in a native setting since they are structurally similar, often essential and display dosage sensitivity. Pharmacological inhibition would be an ideal tool to probe the function of these enzymes. In this work, we describe a chemical genetic strategy for the specific inactivation of individual DEAD-box proteins with small molecule inhibitors using covalent complementarity...

1.Co-existence between great tits Parus major and blue tits Cyanistes caeruleus, but also other hole nesting taxa, constitutes a classic example of species co-occurrence resulting in potential interference and exploitation competition for food and for breeding and roosting sites. However, the spatial and temporal variation in co-existence and its consequences for competition remain poorly understood. 2.We used an extensive database on reproduction in nest boxes by great and blue tits based on 87 study plots across Europe and Northern Africa during 1957-2012 for a total of 19,075 great tit and 16,729 blue tit clutches to assess correlative evidence for a relationship between laying date and clutch size, respectively, and density consistent with effects of intraspecific and interspecific competition...

Carotenoids play important roles in many biological processes, such as light harvesting, photoprotection and visual attraction in plants. However, the regulation of carotenoid biosynthesis is still not fully understood. Here, we demonstrate that SlBBX20, a B-box (BBX) zinc-finger transcription factor, is a positive regulator of carotenoid accumulation in tomato (Solanum lycopersicum). Overexpression of SlBBX20 leads to dark green fruits and leaves and higher levels of carotenoids relative to the wild-type. Interactions between SlBBX20 and DE-ETIOLATED 1 (SlDET1) lead to the ubiquitination and 26S proteasome-mediated degradation of SlBBX20...

Motivation: Computational biologists face many challenges related to data size, and they need to manage complicated analyses often including multiple stages and multiple tools, all of which must be deployed to modern infrastructures. To address these challenges and maintain reproducibility of results, researchers need (i) a reliable way to run processing stages in any computational environment, (ii) a well-defined way to orchestrate those processing stages, and (iii) a data management layer that tracks data as it moves through the processing pipeline...

The albumin D-box binding protein (DBP) is a member of the PAR bZip (proline and acidic amino acid-rich basic leucine zipper) transcription factor family and functions as important regulator of circadian core and output gene expression. Gene expression of DBP itself is under the control of E-box-dependent binding by the Bmal1-Clock heterodimer and CRE-dependent binding by the cAMP responsive element binding protein (CREB). However, the signaling mechanism mediating CREB-dependent regulation of DBP expression in the peripheral clock remains elusive...

Background: There are six known families of homing endonucleases, LAGLIDADG, GIY-YIG, HNH, His-Cys box, PD-(D/E)-XK, and EDxHD, which are characterized by their conserved residues. Previously, we discovered a novel homing endonuclease F-CphI encoded by ORF177 of cyanophage S-PM2. F-CphI does not resemble any characterized homing endonucleases. Instead, the C-terminus of F-CphI aligns well with the N-terminal catalytic domain of a Holliday junction DNA resolvase, phage T4 endonuclease VII (Endo VII)...

Background: Severe musculoskeletal trauma can trigger an inflammatory response, and an excessive inflammatory response can lead to systemic inflammatory response syndrome and multiorgan failure. High-mobility group box 1 (HMGB1) is an early mediator pro-inflammatory cytokine in sterile injuries and a late cytokine mediator in infection and sepsis. Previous research has shown that administration of systemic lidocaine can inhibit HMGB1 expression in macrophages of septic rats. The aim of this study was to demonstrate the efficacy of systemic lidocaine to inhibit HMGB1 mRNA and protein in a BALB/c mouse model of sterile inflammation due to closed fracture musculoskeletal injury...

Ultrasound may convert conjugated isoflavones into their corresponding aglycones, the best form for absorption in the human body. However, ultrasound may also influence the activity of endogenous β-glucosidase. Therefore, the present work evaluated the effects of soybean ultrasound pre-treatment by applying the Box-Behnken design prior to soaking, a step that is important for industries to prepare certain soy products. Furthermore, a multi-response optimisation is provided. The best conditions for soybean ultrasound pre-treatment were established as temperature, X1  = 55 °C; exposure time, X2  = 5 min and ultrasound intensity, X3  = 19...

BACKGROUND: Anti-programmed death-1 (PD-1) treatment for advanced non-small-cell lung cancer (NSCLC) has improved the survival of patients. However, a substantial percentage of patients do not respond to this treatment. We examined the use of DNA methylation profiles to determine the efficacy of anti-PD-1 treatment in patients recruited with current stage IV NSCLC. METHODS: In this multicentre study, we recruited adult patients from 15 hospitals in France, Spain, and Italy who had histologically proven stage IV NSCLC and had been exposed to PD-1 blockade during the course of the disease...

Sister chromatid cohesion, mediated by cohesin, is required for accurate chromosome segregation [1, 2]. This process requires acetylation of cohesin subunit SMC3 by evolutionarily conserved cohesin acetyltransferases: Eco1 in budding yeast; XEco1 and XEco2 in Xenopus; and ESCO1 and ESCO2 in human [3-10]. Eco1 is recruited to chromatin through physical interaction with PCNA [11] and is degraded by the Skp1/Cul1/F-box protein complex after DNA replication to prevent ectopic cohesion formation [12]. In contrast, XEco2 recruitment to chromatin requires prereplication complex formation [13] and is degraded by the anaphase-promoting complex (APC) [14]...

The main objective of this study was to investigate the effects of task execution variables on the value and point of application of the resultant vertical ground reaction force acting on the foot sole during squat lifting. This can be of particular importance since it may help to recognize the roles of the foot sole parts in bearing the support force during industrial and labor lifting activities. Twelve healthy men lifted a box with 4, 8 and 12 kg masses at fast and slow speeds. Ground reaction force and center of pressure were measured using two parallel Kistler force-plates...

The present report studied the role of ultrasound (US) energy in the amyloglucosidase-based starch hydrolysis using two complementary approaches: (i) in the activity of six commercially-available amyloglucosidases (using soluble starch as substrate), and (ii) in the hydrolysis of four pure starches from different botanical sources. This corresponds to the first systematic evaluation of the role of US in starch hydrolysis mediated by amyloglucosidase, being a consequence of our previous report that assessed the effect of US in the activity of alpha-amylase (LWT - Food Science and Technology 84 (2017) 674-685)...

Long non-coding RNAs (lncRNAs) play an important role in the proliferation and metastasis of osteosarcoma. Identification of the pathogenesis osteosarcoma and development of new therapeutic strategies against osteosarcoma are urgently needed. In this study, we evaluated the expression of TUG1 (Taurine Upregulated Gene 1) in osteosarcoma tissues and selected it as our target for further analyses. In vitro, we found that TUG1 was up-regulated by FOXM1 (Forkhead Box M1) in osteosarcoma cells. TUG1 accelerated osteosarcoma proliferation, migration, and invasion by competitively sponging miR-219a-5p, leading to up-regulation of PIK3CA and activation of the AKT signaling pathway...
