Context. Hot coronal jets are a basic observed feature of the solar atmosphere whose physical origin is still actively debated.
Aims. We study six recurrent jets that occurred in active region NOAA 12644 on April 4, 2017. They are observed in all the hot filters of AIA as well as cool surges in IRIS slit–jaw high spatial and temporal resolution images.
Methods. The AIA filters allow us to study the temperature and the emission measure of the jets using the filter ratio method. We studied the pre-jet phases by analysing the intensity oscillations at the base of the jets with the wavelet technique.
Results. A fine co-alignment of the AIA and IRIS data shows that the jets are initiated at the top of a canopy-like double-chambered structure with cool emission on one and hot emission on the other side. The hot jets are collimated in the hot temperature filters, have high velocities (around 250 km s−1) and are accompanied by cool surges and ejected kernels that both move at about 45 km s−1. In the pre-phase of the jets, we find quasi-periodic intensity oscillations at their base that are in phase with small ejections; they have a period of between 2 and 6 min, and are reminiscent of acoustic or magnetohydrodynamic waves.
Conclusions. This series of jets and surges provides a good case study for testing the 2D and 3D magnetohydrodynamic emerging flux models. The double-chambered structure that is found in the observations corresponds to the regions with cold and hot loops that are in the models below the current sheet that contains the reconnection site. The cool surge with kernels is comparable with the cool ejection and plasmoids that naturally appears in the models.

Context. Observations of exoplanetary systems demonstrate that a wide variety of planetary architectures are possible. Determining the rate of occurrence of Solar System analogues – with inner terrestrial planets and outer gas giants – remains an open question.
Aims. Within the framework of the Global Architecture of Planetary Systems (GAPS) project, we collected more than 300 spectra with HARPS-N at the Telescopio Nazionale Galileo for the bright G9V star HD 164922. This target is known to host one gas giant planet in a wide orbit (Pb ~1200 days, semi-major axis ~ 2 au) and a Neptune-mass planet with a period of Pc ~76 days. We aimed to investigate the presence of additional low-mass companions in the inner region of the system.
Methods. We compared the radial velocities (RV) and the activity indices derived from the HARPS-N time series to measure the rotation period of the star and used a Gaussian process regression to describe the behaviour of the stellar activity. We then combined a model of planetary and stellar activity signals in an RV time series composed of almost 700 high-precision RVs, both from HARPS-N and literature data. We performed a dynamical analysis to evaluate the stability of the system and the allowed regions for additional potential companions. We performed experiments on the injection and recovery of additional planetary signals to gauge the sensitivity thresholds in minimum mass and orbital separation imposed by our data.
Results. Thanks to the high sensitivity of the HARPS-N dataset, we detected an additional inner super-Earth with an RV semi-amplitude of 1.3 ± 0.2 m s−1 and a minimum mass of md sin i = 4 ± 1 M⊕. It orbits HD 164922 with a period of 12.458 ± 0.003 days. We disentangled the planetary signal from activity and measured a stellar rotation period of ~ 42 days. The dynamical analysis shows the long-term stability of the orbits of the three-planet system and allows us to identify the permitted regions for additional planets in the semi-major axis ranges 0.18–0.21 au and 0.6–1.4 au. The latter partially includes the habitable zone of the system. We did not detect any planet in these regions, down to minimum detectable masses of 5 and 18 M⊕, respectively. A larger region of allowed planets is expected beyond the orbit of planet b, where our sampling rules out bodies with minimum mass >50 M⊕. The planetary orbital parameters and the location of the snow line suggest that this system has been shaped by a gas disk migration process that halted after its dissipation.

Abstract
Introduction Scarring and volume reduction of the axillary space resulting in persistent lymphedema is a side effect of axillary treatment in breast cancer patients. The aim of this paper is to describe the reduction of lymphedema achieved with a turnover flap.
Materials and Methods Between October 2016 and May 2018, five patients with grade 2 lymphedema following breast cancer therapy underwent reconstructive surgery with a turnover flap. Complete excision of the symptomatic axillary scar tissue followed by re-augmentation using a turnover flap was performed. Subsequently, all patients underwent breast reconstruction using a distant flap reconnected to the thoracodorsal vessels. The circumference of both arms, quality of life and pain were measured before and after surgery.
Results An average reduction in pain in the ipsilateral arm from 6 to 1 on the numerical scale as well as an improvement in quality of life (2.8 vs. 7.0) was observed. A decrease in lymphedema especially in the upper arm was identified. No complications such as secondary bleeding, infections or flap loss were observed.
Conclusion Complete removal of the axillary scar tissue after breast cancer treatment and re-augmentation of the axilla with a turnover flap results in a reduction in ipsilateral lymphedema and an improvement in pain and quality of life. We interpret these findings as a result of the physiological re-alignment of the lymphatic vessels combined with a lymph node-containing local transposition flap. Therefore, re-augmentation with a turnover flap could be an effective non-microsurgical alternative to lymph node transplantation.
Revision Arthroplasty with Total Femur Replacement for the Management of Complex Post-traumatic Bone Defect in a Patient with Dwarfism

Published: May 2020

AbstractDwarfism leads to an early onset of osteoarthritis of the joints of the lower limb. Due to bone deformities, arthroplasty is challenging. The incidence of implant-associated complications is higher compared to the normal population and often ends up with multiple revision arthroplasties. We report the first case in the literature of a 48-year-old patient with dwarfism who required implantation of a custom-made total femoral replacement due to aseptic stem loosening and a concomitant valgus gonarthrosis.
Anti-inflammatory Potential of Macamides Isolated from Yellow Tubers

Published: May 2020

AbstractAlthough Tropaeolum tuberosum tubers have been consumed cooked as a folk
remedy for the treatment of skin, lungs, liver and kidneys diseases, these uses
have very limited scientific basis. Therefore, this article develops a
phytochemical analysis of the yellow tubers of T. tuberosum with the
objective to assess whether the isolated compounds have anti-inflammatory
potential in the CCD-1109Sk, MRC-5 and RWPE-1 cell lines. We performed an
extraction of T. tuberosum tubers using different organic solvents,
followed by a bioguided chromatographic separation. Four macamides were
identified by LC/MS techniques, but only N-benzyllinoleamide
(1) and N-benzyloleamide (2) were isolated and
elucidated by NMR/MS techniques, given that they were present in a
larger proportion in the tubers. The anti-inflammatory potential of macamides
was evaluated by the inhibition of NF-κB and STAT3 activation. Both
compounds displayed inhibition of NF-κB activation with IC50
values of 2.28±0.54 µM;
3.66±0.34 µM and
4.48±0.29 µM for compound (1) and
6.50±0.75 µM;
7.74±0.19 µM and
8.37 ±0.09 µM for compound (2)
in CCD-1109Sk, MRC-5 and RWPE-1 cell lines, respectively. Moreover, both
compounds inhibited the STAT3 activation with IC50 of
0.61±0.76 µM;
1.24±0.05 µM and
2.10±0.12 µM for compound (1) and
5.49±0.31 µM;
7.73 ±0.94 µM and
7.79±0.30 µM for compound (2).
Therefore, isolated macamides of T. tuberosum tubers showed promising
anti-inflammatory effects, suggesting a possible beneficial use to combat
inflammatory processes of skin, lung and prostate.
Abdominal Radiograph

Published: May 2020

AbstractAbdominal radiograph (AR) is often the initial radiological investigation performed while investigating abdominal pain even today. However, in the era of cross-sectional imaging, the role of AR in the diagnosis of acute pain abdomen is being questioned. When AR is used as a screening modality, the diagnostic yield is low. When performed in suspected cases of bowel obstruction or perforation, urinary calculi, or bowel ischemia, AR is often helpful. AR is often the first radiological investigation performed in acute abdomen. Although the role of plain radiograph is limited in the era of cross-sectional imaging, systemic approach and vigilant search for the radiological features on AR may be diagnostic and decide further line of investigation. Various gas patterns of intraluminal and free peritoneal air are helpful in localizing pathology. Different patterns of calcification seen in abdomen, ingested or inserted foreign bodies, and location of medical devices give a clue to diagnosis.

ALKALINE PHOSPHATASE – A DIAGNOSTIC MARKER OF PERIODONTITIS IN POSTMENOPAUSAL WOMEN – A. B. OCHEMICAL STUDY
Authors: Ramesh Amitha , Bhandary Rahul , Thomas Biju , D'Souza Sheehan R. , Kumari Suchetha 
Published: May 2020

Abstract
Background and objective: Periodontal disease is one of the common inflammatory diseases with complex etiology and is multifactorial in origin.Several enzymes are evaluated for the early diagnosis of periodontal disease. The enzyme ALP plays a role in bone metabolism. In the periodontium, ALP is very important enzyme as it is part of normal turnover of periodontal ligament, root cementum, and bone homeostasis. The deficiency of estrogen in women at menopause is contributing factor to osteoporosis and considered one of the risk factors for periodontal disease. It has been hypothesized that osteoporosis decreases alveolar bone density and in turn increases its susceptibility to resorption due to periodontal inflammation. Accelerated bone loss in menopause is related to increased bone turnover. This is accompanied by increased levels of biochemical markers such as Alkaline Phosphatase. Alteration in salivary Alkaline Phosphatase levels might be expected as an indication of periodontal disease activity.
Methods: The study included 40 subjects, 20 in each group in the age group of 50-60 years. Group 1 comprised of 20 Postmenopausal women without chronic periodontitis. Group 2 comprised of 20 Postmenopausal women with chronic periodontitis. Each saliva sample was estimated for ALP levels.
Results: The present study showed significant increase in Alkaline Phosphatase in postmenopausal women with periodontitis (Group 2) with p value <0.0001.
Interpretation and conclusion: Alkaline phosphatase can be used as a diagnostic marker of Periodontitis in postmenopausal women. However ALP cannot be solely responsible for Periodontitis but it can be used as a additional aid in diagnosing Periodontitis.

RENAL CELL CARCINOMA WITH OSSEOUS METAPLASIA OCCURRING IN A CONTRACTED KIDNEY - A RARE CASE REPORT
Authors: Permi Harish S. 
Published: May 2020

AbstractOsseous metaplasia is a rare histologic feature associated with renal cell carcinoma, occurring in a contracted kidney is still rarer. Metaplastic bone formation within the renal tumor gives an appearance similar to that of calcification. It is difficult to distinguish between bone formation and calcification on the basis of radiological imaging alone. Prognostic significance of metaplastic bone formation in renal cell carcinoma is not clear, however some report suggest good prognosis as a result of limitation of tumor spread by bone formation. This case report highlights the occurrence of renal cell carcinoma with osseous metaplasia in a contracted kidney.
Hereditary Tyrosinemia Type 1—A Rare Disease with Typical Radiological Features: Case Report and Review of Literature
Authors: Singh Somesh , Mall Rana Vishwadeep , Chaturvedi Pragya , Yadav Rajnikant R. 
Published: May 2020

AbstractHereditary tyrosinemia type 1 is one of the many inborn errors of metabolism associated with tyrosine catabolism. It is a rare disease with its incidence or prevalence in India unknown. The cascading alternate metabolism results in characteristic injury patterns to the liver, kidneys, and the central nervous system, with resultant classical radiological findings. Identifying this constellation of imaging features by a radiologist may help in arriving at a diagnosis and help referring physicians in performing appropriate biochemical tests and instituting early treatment. These usually present with chronic liver failure and are extensively evaluated for other causes of liver failure. We present a case type 1 hereditary tyrosinemia with characteristic radiological features and highlight its pathophysiology to understand the basis of these imaging findings.
The Role of the Posterolateral Tibial Slope in the Rotational Instability of the Knee in Patients Affected by a Complete Isolated Anterior Cruciate Ligament Injury: Its Value in the Decision-Making Process during the Anterolateral Ligament Reconstruction

Published: May 2020

Abstract
Purpose The aim of this retrospective, multicenter study was to investigate the correlation between a high degree of rotatory instability, posterolateral tibial slope (PLTS), and anterolateral ligament (ALL) injury.
Methods The study population consisted of 76 adults with isolated, complete noncontact anterior cruciate ligament (ACL) tear. The sample was divided into two groups according to the preoperative degree of rotator instability (group A: pivot-shift test grades 2 and 3; group B: pivot-shift test grade 1). Preoperative magnetic resonance imaging (MRI) assessment included angle of PLTS, posterior shift of the lateral femoral condyle (16 mm) on the tibial plateau, and the presence/absence of ALL injury. The two groups were compared for differences.
Results There was a statistically significant association between pivot-shift test grades 2 and 3 (group A), PLTS slope angle > 9 degrees, and ALL injury (p < 0.05). Group A also demonstrated a greater posterior shift of lateral femoral condyle (>11 mm), which was, however, not statistically significant when evaluated as an isolated variable.
Conclusion Our study indicates that an increased PLTS is associated with an increased incidence of ALL injury and an increased grade of pivot shift in patients with ACL tear. Assessment of posterolateral tibial slope on MRI can therefore play a key adjunct role in the surgical planning of ALL reconstruction, especially in cases when ALL damage is radiologically difficult to detect or doubtful.
Level of Evidence This is a retrospective comparative level III study.
