  The management of gingival recession associated with esthetic concerns and root hypersensitivity is challenging, and its sequelae is based on the assessment of etiological factors and the degree of tissue involvement. Procedures using pedicle flaps, free soft tissue grafts, combination of pedicle flaps with grafts, barrier membranes, and the use of platelet concentrates are all effective for this purpose. The use of the third-generation platelet concentrate, advanced platelet-rich fibrin (A-PRF), has evolved as a promising regenerative material for root coverage procedure wherein it acts as a scaffold and also accelerates wound healing due to its dense fibrin meshwork.
 
  This case report, discusses treating an isolated maxillary Miller Class I recession in a 25-year-old male patient by a periosteal inversion method along with the A-PRF membrane. A partial thickness flap was reflected; periosteum was inverted; and an A-PRF membrane was placed over the denuded root surface which aided in enhanced regeneration; 100% root coverage was obtained as seen in follow-up visits.
 
  The periosteal inversion technique along with an A-PRF membrane seems to be a novel approach in managing an isolated Miller Class I maxillary gingival recession.

The potency of fentanyl analogs can be estimated from in vitro studies and can be used to establish structure-activity relationships. In this study, recombinant CHO-K1 cells (AequoScreen) expressing the human μ-opioid receptor were used to establish dose-response curves via luminescent analysis for cyclopropyl-, cyclobutyl-, cyclopentyl-, cyclohexyl-, and 2,2,3,3-tetramethylcyclopropylfentanyl (TMCPF), on three separate occasions, using eight different concentrations in an eight-fold serial dilution in triplicates starting at ~60 μM.  https://www.selleckchem.com/products/VX-770.html  Fentanyl was used as a full agonist reference while morphine and buprenorphine were included for comparison. Cyclopropylfentanyl (EC50 = 4.3 nM), cyclobutylfentanyl (EC50 = 6.2 nM), and cyclopentylfentanyl (EC50 = 13 nM) were full agonists slightly less potent than fentanyl (EC50 = 1.7 nM). Cyclohexylfentanyl (EC50 = 3.1 μM, efficacy 48%) and TMCPF (EC50 = 1.5 μM, efficacy 65%) were partial agonists less potent than morphine (EC50 = 430 nM). Based on the results, cyclopropyl-, cyclobutyl-, and cyclopentylfentanyl would be expected to induce intoxication or cause fatal poisonings at similar concentrations to fentanyl, while the toxic or fatal concentrations of cyclohexylfentanyl and TMCPF would be expected to be much higher.
  Sarcoidosis is a systemic granulomatous disease affecting in particular the respiratory tract. Cardiac magnetic resonance (CMR), including a measurement of T
  relaxation time, could potentially detect early stadia of sarcoidosis of the heart. The study aims to assess T
  mapping in the detection of early cardiac involvement in asymptomatic patients with sarcoidosis.
 
  One hundred and twenty patients with extracardiac sarcoidosis and without any heart disease history were included. One hundred and thirteen of them underwent a CMR examination. The mean time from the diagnosis of sarcoidosis was 0.8 (0.2-3.3) years. Cine images for the assessment of left ventricular (LV) functional parameters and pre- and post-contrast saturation method using adaptive recovery times for cardiac T
  mapping (SMART
  Map) and modified Look-Locker inversion recovery (MOLLI) images were acquired for the assessment of native T
  relaxation time and extracellular volume (ECV). The measured parameters were compared between sarcoidosis patients and 22 controls.
 
  The sarcoidosis patients had normal global and regional systolic LV function-LV ejection fraction 65 ± 5% versus 66 ± 7% (p NS). The mean native T
  relaxation times were not prolonged-1465 ± 93 ms versus 1480 ± 88 ms (p NS) measured by SMART
  Map and 1317 ± 60 ms versus 1313 ± 83 ms (p NS) measured using a MOLLI sequence. Similarly, the mean ECV values did not increase-16.9 ± 3.9% versus 17.9 ± 3.7% (p NS) measured by SMART
  Map and 30.9 ± 2.9% versus 31.6 ± 8.3% (p NS) measured using a MOLLI sequence.
 
  Myocardial native T
  relaxation times were not prolonged and ECV was not increased in asymptomatic patients with extracardiac sarcoidosis.
 Myocardial native T1 relaxation times were not prolonged and ECV was not increased in asymptomatic patients with extracardiac sarcoidosis.Radiotherapy is an important adjuvant treatment for large intestine cancer even though it does not cause any response in many patients. The present study aimed to investigate the effects of the TTN antisense RNA 1 (TTN-AS1) long noncoding RNA (lncRNA) on radiotherapy dynamics of large intestine cancer cells and to explore the underlying molecular mechanisms. TTN-AS1 expression was evaluated by reverse-transcription quantitative polymerase chain reaction, western blot, and cellular immunofluorescence, and flow cytometry analysis was used to measure apoptosis. Radiotherapy was simulated in vitro by exposing cancer cells to X-ray. TTN-AS1 was highly expressed in large intestine cancer cells after an X-ray exposition for 24 hr. TTN-AS1 knockdown improved the radiosensitivity of large intestine cancer cells and promoted apoptosis by increasing Bax/Bcl2 protein expression and the active-caspase 3/caspase 3 ratios following X-ray treatment. In addition, TTN-AS1 negatively regulated miR-134-5p expression, and miR-134-5p-mimic transfection decreased PAK3 protein expression in large intestine cancer cells. Importantly, TTN-AS1 promoted PAK3 and P21 protein expression in HT29 cells after X-ray treatment. Moreover, the knockdown of P21 protein expression improved radiosensitivity and promoted X-ray-induced apoptosis of HT29 cells. Finally, PAK3 knockdown expression decreased the p-AKT/AKT and p-GSK-3β/GSK-3β ratios and promoted the β-catenin transfer from the nucleus to the cytoplasm. These data suggest that the TTN-AS1 lncRNA promoted resistance to radiotherapy of large intestine cancer cells by increasing PAK3 expression via miR-134-5p inhibition, and this may be related to the P21 and AKT/GSK-3β/β-catenin pathway.
