Abstract
Mastcam-Z is a multispectral, stereoscopic imaging investigation on the Mars 2020 mission's Perseverance rover. Mastcam-Z consists of a pair of focusable, 4:1 zoomable cameras that provide broadband red/green/blue and narrowband 400-1000 nm color imaging with fields of view from 25.6° × 19.2° (26 mm focal length at 283 μrad/pixel) to 6.2° × 4.6° (110 mm focal length at 67.4 μrad/pixel). The cameras can resolve (≥ 5 pixels) ∼0.7 mm features at 2 m and ∼3.3 cm features at 100 m distance. Mastcam-Z shares significant heritage with the Mastcam instruments on the Mars Science Laboratory Curiosity rover. Each Mastcam-Z camera consists of zoom, focus, and filter wheel mechanisms and a 1648 × 1214 pixel charge-coupled device detector and electronics. The two Mastcam-Z cameras are mounted with a 24.4 cm stereo baseline and 2.3° total toe-in on a camera plate ∼2 m above the surface on the rover's Remote Sensing Mast, which provides azimuth and elevation actuation. A separate digital electronics assembly inside the rover provides power, data processing and storage, and the interface to the rover computer. Primary and secondary Mastcam-Z calibration targets mounted on the rover top deck enable tactical reflectance calibration. Mastcam-Z multispectral, stereo, and panoramic images will be used to provide detailed morphology, topography, and geologic context along the rover's traverse; constrain mineralogic, photometric, and physical properties of surface materials; monitor and characterize atmospheric and astronomical phenomena; and document the rover's sample extraction and caching locations. Mastcam-Z images will also provide key engineering information to support sample selection and other rover driving and tool/instrument operations decisions.

Abstract
Abstract
The fourth target of Sustainable Development Goal (SDG) 3 advocates for the promotion of mental health and wellbeing. The Indian state of Kerala is recognized for its gains in health and development but has substantial burden of mental health ailments. Historical analysis is vital to understand the pattern of mental health morbidity. The current study focusses on comparable estimates available from three largescale population-based surveys in India to explore trends in prevalence of mental health disorders over the years and map resources and infrastructure available for mental health care in Kerala.
We undertook a secondary analysis of national demographic surveys from 2002 to 2018 which reported information on mental health and availability of health infrastructure and human resources. Data were collated and descriptive analyses were conducted. We compared the national and state level estimates over the years to study the trend in the prevalence of mental health disability.
The prevalence of mental retardation and intellectual disability in Kerala increased from 194 per hundred thousand persons in 2002 to 300 per hundred thousand persons in 2018, two times higher to the national average. The prevalence of mental illness increased from 272 per hundred thousand people to 400 per hundred thousand people in sixteen years. The prevalence was higher among males (statistical significance was not indicated) in mental illness and mental retardation. 2018 data showed that the public sector had 0.01 hospitals and 5.53 beds per hundred thousand persons available for mental health treatment.
Results showed a substantial increase in mental health illness over the 16-year study period that has affected males and females, as well as all social classes of the state. The current health infrastructure and human resources in the public sector of the state are inadequate to meet the current burden of the problem and to ensure universal access to care for its population.
Key messages
The trend in prevalence of mental health disorders in the state is increasing across the years. There is a mismatch between the extend of the problem and resources available in public sector.

Abstract
Novel macrocyclic Schiff base complexes [[ML]X; where M = Cu(II), Co(II), Ni(II), Zn(II), Mn(II) and VO(IV); L = macrocyclic ligand; X = Cl2 and SO42-] have been synthesized and characterized by microanalytical, 1H, 13C NMR, IR, Mass, UV-Vis, EPR spectral studies, as well as conductivity data. All the complexes exhibit square-planar geometry except vanadium complex. Magnetic susceptibility measurements and high conductance data reveal the monomeric and electrolytic nature of the complexes. Electronic absorption, cyclic voltammetry, viscosity measurements have been carried out on the interaction of the complexes with DNA. The results suggest that the complexes bind to DNA by intercalation via the aromatic ring of the macrocycle into the base pairs of DNA. Using gel electrophoresis experiment in the presence and absence of oxidant (H2O2) the nuclease cleavage activity of the complexes has been performed on plasmid DNA. The results demonstrate that most of the complexes have promising superoxide dismutase (SOD)-mimetic activity. The in vitro cytotoxicity of ligand and its complexes has also been evaluated against human breast and colon carcinoma cells. Binding interactions and energies of ligand and its metal complexes [ML]2+ (M = VO(IV), Mn(II), Co(II), Ni(II), Cu(II), Zn(II)) against the receptors EGFR and HER2 are performed using the Auto dock module. Consequently, it is found that the ligand is strong inhibitor for EGFR and HER2 while [VOL]SO4 is good inhibitor for EGFR and [ZnL]Cl2 is moderate inhibitor for HER2. The antimicrobial activity of the ligand and its complexes against bacteria Salmonella typhi, Staphylococcus aureus, Escherichia coli and Bacillus subtilis and fungi Aspergillus niger, Aspergillus flavus, Candida Albicans and Rhizoctonia bataicola. The complexes have higher activities than the macrocyclic free Schiff base. Interaction of [VOL]SO4 to the binding sites of target protein EGFR (PDB ID: 4HJ0). Research HighlightsMacrocyclic Schiff base and its metal complexes were synthesized.Complexes bind to DNA by intercalation via the aromatic ring of the macrocycle into the base pairs of DNA.Vanadyl complex is a good inhibitor for EGFR.The complexes of copper, zinc and vanadium show efficient antitumor activity.Copper and vanadium complexes have superior antimicrobial activity than the standards.

Abstract
OBJECTIVE Neonates and infants are patients who would benefit from less invasive vital sign sensing, especially from fewer cables and the avoidance of adhesive electrodes. Photoplethysmography imaging (PPGI) has been studied for medical applications in recent years: it is possible to assess various vital signs remotely, non-invasively, and without contact by using video cameras and light. However, studies on infants and especially on neonates in clinical settings are still rare. Hence, we conducted a single-center study to assess heart activity by estimating the pulse rate (PR) of 19 neonates. APPROACH Time series were generated from tracked regions of interest (ROIs) and PR was estimated via a joint time-frequency analysis using a short-time Fourier transform. Artifacts, for example, induced by movement, were detected and flagged by applying a signal quality index in the frequency domain. MAIN RESULTS The feasibility of PR estimation was demonstrated using visible light and near-infrared light at 850 nm and 940 nm, respectively: the estimated PR was as close as 3 heartbeats per minute in artifact-free time segments. Furthermore, an improvement could be shown when selecting the best performing ROI compared to the ROI containing the whole body. The main challenges are artifacts from motion, light sources, medical devices, and the detection and tracking of suitable regions for signal retrieval. Nonetheless, the PR extracted was found to be comparable to the contact-based photoplethysmography reference and is, therefore, a viable replacement if robust signal retrieval is ensured. SIGNIFICANCE Neonates are seldom measured by PPGI and studies reporting measurements on darker skin tones are rare. In this work, not only a single camera was used, but a synchronized camera setup using multiple wavelengths. Various ROIs were used for signal extraction to examine the capabilities of PPGI. In addition, qualitative observations regarding camera parameters and noise sources were reported and discussed.

Abstract
Vision assessments were provided to 297 Head Start children in nine Westchester County, New York programs. An optometrist and an orthoptist administered a protocol which included retinoscopy, visual acuity, fly, cover, motility and convergence tests. Sixty-three children (21.2%) were referred for further evaluation. The visual deficits detected by this screening included decreased acuity, strabismus combined with decreased acuity, astigmatism, and nonspecific visual problems. The protocol used provided a thorough evaluation of the visual system and required only seven minutes per patient.

Abstract
A 36-year-old patient presented with an 18-month history of intermittent right parotid swelling accompanied by otorrhoea. The symptoms started subsequent to a palm leaf injury to the right ear. At right parotidectomy, a fistula connecting the right external auditory canal and the right parotid was demonstrated. A small fibrotic mass probably due to a remnant of the palm leaf was found intraoperatively. The symptoms resolved completely after the mass was excised by superficial parotidectomy, and the fistula closed spontaneously.

Abstract
Abstract
Background
Low gradient severe aortic stenosis (LGAS) is associated with unfavourable outcomes when compared to high gradient aortic stenosis (HGAS), yet the contributing pathophysiology is poorly understood.
Methods
Symptomatic LGAS and HGAS patients undergoing trans-catheter aortic valve implantation (TAVI) underwent 3T stress perfusion cardiac magnetic resonance imaging (CMR) pre-(within 24 hours) and post-(4–6 months) TAVI. Left ventricular (LV) contractility and coronary flow/pressure were measured during hyperaemia and rapid pacing, immediately before and after TAVI, using a conductance LV catheter and dual-pressure and Doppler sensor–tipped guidewire in the mid-left anterior descending coronary artery.
Results
24 patients were recruited resulting in 19 suitable datasets (LGAS N=9, HGAS N=10, equally matched for comorbidities and B-natriuretic peptide level). LGAS patients had a smaller LV end diastolic volume index (p=0.035) and lower LV mass index (LVMI) (p=0.037). Pre-TAVI stress global endocardium-epicardium gradient was 0.88±0.09 and global myocardial perfusion reserve (MPR) 2.0±0.48 in 14 patients (6 LGAS and 8 HGAS patients, no difference between groups). Pre-TAVI, baseline coronary data demonstrated lower augmentation pressure (AP, p=0.035) and augmentation index (AIx, p=0.02) in the LGAS group. LGAS patients also exhibited a shorter ejection time (p=0.015), larger forward compression waves during rest, hyperaemia and rapid pacing, and smaller backward expansion waves (BEW) (p=0.001). Lower baseline end systolic pressure (p=0.004), inotropy (dP/dt+, p=0.045), lusitropy (dP/dt-, p=0.069), and stroke work (p=0.019) were observed in the LGAS group. Whilst LV size was smaller the LGAS group, rapid pacing induced a more significant drop in end systolic volume (p=0.045) and ejection fraction (p=0.015) in patients with HGAS. Post-TAVI, the hyperaemic BEW fell sharply (p<0.001), along with coronary VTI (p=0.02), and average pulse velocity (p=0.028), and AP and AIx remained lower (p=0.034 and p=0.031, respectively). The forward expansion wave was reduced in LGAS during rapid pacing. The HGAS group displayed a more profound drop in dP/dt+ (p=0.011) and dP/dt- p=0.014) at rest following intervention. Repeat CMR demonstrated statistically significant reduction in LV size and LVMI (p=0.012 and p<0.001, respectively) with significant increase in 3D global peak radial, circumferential and longitudinal strain (p=0.004, p=0.001 and p=0.018, respectively). Post-TAVI stress global endocardium-epicardium gradient was 0.88±0.13 and MPR 2.46±0.59 (improved from pre-TAVI, p=0.05). There was no difference in remodelling patterns or perfusion between the two groups.
Conclusion
This is the first study detailing the combined invasive and CMR pathophysiological changes in LGAS. Despite invasive parameters indicating a disease of less severe AS, the level of perfusion abnormality is disproportionate which may in part, relate to their adverse prognosis.

Abstract
Unilateral absence of pulmonary artery or pulmonary artery agenesis (UAPA) is a rare congenital malformation that can present as an isolated lesion or in association with other cardiac anomalies. Though congenital, presentation in adults are also reported. Most common presentation in adults is of exercise intolerance. The developing lung on the affected side is hypoplastic. Diagnosis of UAPA is established by imaging methods like CT and MRI. There is no specific treatment for this condition. Treatment depends on patients symptomatology, presence of pulmonary hypertension and collateral circulation. Presence of pulmonary hypertension carries a bad prognosis. We present two adult patients with isolated left sided unilateral pulmonary artery agenesis with ipsilateral lung hypoplasia. The diagnosis was confirmed by CT chest and perfusion scan.

Abstract
CYFRA 21–1, CEA, CA 125, SCC and NSE serum levels were determined in 50 healthy subjects and in 189 patients with primary lung cancer (101 with locoregional disease, 68 with recurrence and 20 patients with no evidence of residual disease (NED). Abnormal CYFRA 21–1 serum levels were found in 53.6% (90/168) of the patients with active cancer. Neither healthy subjects nor NED patients had abnormal serum levels. CYFRa 21–1 serum concentrations were significantly higher in patients with active cancer than in healthy subjects or in NED patients (p < 0.0001). CYFRA 21–1 sensitivity was related to tumor histology with abnormal levels in 64.7% of patients with NSCLC and in 30% of patients with SCLC (P <0.0001). In NSCLC, serum CYFRA 21–1 concentrations were also related to histological type, the highest values being found in squamous cell carcinomas and LCLC and the lowest in adenocarcinomas (p < 0.04). There was also a clear relationship between CYFRA 21–1 and tumor extension, with significantly higher values in patients with metastases than in those without metastases (p < 0.0001). Abnormal CEA values were found in 49.1%, CA 125 in 39%, SCC in 27.8% and NSE in 21.3% of the patients with active cancer. With respect to histological type, CYFRA was elevated in 68.3% of squamous cell carcinomas (CEA: 46.7%, SCC: 50%, CA 125:31.7%, NSE: 11.7%), in 54.8% of adenocarcinomas (CEA: 62%, SCC: 26.2%, CA 125: 59.5%, NSE: 9.5%), in 78.6% of LCLC (CEA: 64.3%, SCC: 28.6%, CA 125: 78.6%, NSE: 7.1%) and in 30% of SCLC (CEA: 37.7%, SCC: 3.8%, CA 125:20.8%, NSE: 45.3%). In summary, CYFRA 21–1 is the most sensitive tumor marker in patients with lung cancer, especially in NSCLC patients.

Abstract
Mucin-like Carcinoma-associated Antigen (MCA) has been associated with many breast cancers. The aim of this study was to evaluate MCA in tumor tissue and serum as a potential tumor marker for prognosis and disease monitoring. MCA levels were determined in the tissue of 196 patients with primary breast cancer, 25 with metastatic disease and 25 patients with benign diseases, in pellet and/or cytosol. MCA levels were also determined in the serum of 50 patients with benign diseases, 148 with primary breast cancer (Mo), 150 with metastatic breast cancer (MT), and 200 with no clinical evidence of disease (NED). MCA tissue concentrations in pellet and cytosol were similar: 66.7 + 251 U/mg and 41.1 + 53 U/mg, respectively. No relationship between MCA levels and tumor size or nodal involvement was found. Higher MCA levels were observed in patients with ER + or PgR + tumors than in those with ER- or PgR- tumors (p < 0.01). Patients with MCA pellet concentrations lower than 10 U/mg of protein had shorter disease - free intervals (DFI) than those with higher values (p < 0.05). Abnormally high serum levels of MCA were found in 8% of patients with benign diseases, 4% of NED patients, 22% of Mo patients, and in 76% of MT cases. In primary breast cancer MCA values were related to tumor size and nodal involvement. A trend toward a lower DFI in patients with elevated presurgical MCA levels was observed but was of no statistical significance. These differences became statistically significant when patients were subdivided according to nodal status, with shorter DFI in those without nodal invasion (p < 0.05). In metastatic patients, changes in serum MCA were related to the tumor's response to treatment in 82% of cases. The highest MCA values were found in patients with liver or bone metastasis and the lowest values were found in those with locoregional recurrence. In conclusion, although MCA is not a specific tumor marker, it can be useful as a prognostic factor (tissue and serum) and in monitoring metastatic patients.
