The effect of Yasthimadhu Ghrita Pichu in Cervical Erosion - A Case Study

Cervical erosion is a physiological state after menarche; the columnar epithelium within the endocervical canal grows and everts exposing the glandular epithelium on the ecto-cervix. The exposed glandular epithelium is gradually replaced by squamous epithelium. Mostly occurs during child bearing age with the symptoms like vaginal discharge, itching, pelvic pain, post coital bleeding dyspareunia. If it is not treated properly leads to cervical cancer. This case study is of a female patient who complained of cervical erosion which was treated with Ayurvedic Stanika Chikitsa - Yonidhavana with Nimba Patra Prakshalana and Yastimadhu Ghrita  Pichu for 7 days. In the present study, Pichu with Yashtimadhu Ghrita is proved to give good results in cervical erosion. Hence the clinical trial can be done in large number of patients to see further results

PG1004+130: Hybrid Morphology Source or a Restarted FRII? A uGMRT Polarimetric Investigation

We present here the polarization image of the hybrid morphology (HYMOR) and broad-absorption line (BAL) quasar PG1004+130 at 694~MHz obtained with the upgraded Giant Metrewave Radio Telescope (uGMRT). We detect linear polarization in this source's core, jets, and lobes. The visible discontinuity in total intensity between the inner jets and the kpc-scale lobes suggests that the source is restarted. The inferred poloidal magnetic (B-) field structure in the inner jet is consistent with that observed in Fanaroff-Riley (FR) type II sources, as are the B-fields aligned with the lobe edges. Moreover, archival Chandra and XMM-Newton data indicate that PG1004+130 displays several FRII-jet-like properties in X-rays. We conclude that PG1004+130 is a restarted quasar, with both episodes of activity being FRII type. The spectral index images show the presence of an inverted spectrum core ($\alpha=+0.30\pm0.01$), a steep spectrum inner jet ($\alpha=-0.62\pm0.06$) surrounded by much steeper lobe emission ($\alpha\approx-1.2\pm0.1$), consistent with the suggestion that the lobes are from a previous activity episode. The spectral age difference between the two activity episodes is likely to be small ($<1.2 \times 10^7$ years), in comparison to the lobe ages ($\sim 3.3\times 10^7$ years). The inferred B-fields in the lobes are suggestive of turbulence and the mixing of plasma. This may account for the absence of X-ray cavities around this source, similar to what is observed in M87's radio halo region. The depolarization models reveal that thermal gas of mass $\sim (2.4\pm0.9)\times 10^9$ M$_\odot$ is mixed with the non-thermal plasma in the lobes of PG1004+130.Comment: 14 pages, 5 figures, accepted for publication in The Astrophysical Journa

A 9.38-bit, 422nW, high linear SAR-ADC for wireless implantable system

In wireless implantable systems (WIS) low power consumption and linearity are the most prominent performance metrics in data acquisition systems. successive approximation register-analog to digital converter (SAR-ADC) is used for data processing in WIS. In this research work, a 10-bit low power high linear SAR-ADC has been designed for WIS. The proposed SAR-ADC architecture is designed using the sample and hold (S/H) circuit consisting of a bootstrap circuit with a dummy switch. This SAR-ADC has a dynamic latch comparator, a split capacitance digital to analog converter (SC-DAC) with mismatch calibration, and a SAR using D-flipflop. This architecture is designed in 45 nm CMOS technology. This ADC reduces non-linearity errors and improve the output voltage swing due to the usage of a clock booster and dummy switch in the sample and hold. The calculated outcomes of the proposed SAR ADC display that with on-chip calibration an ENOB of 9.38 (bits), spurious free distortion ratio (SFDR) of 58.621 dB, and ± 0.2 LSB DNL and ± 0.4LSB INL after calibration

A Polarization Study of 3 Blazars using the uGMRT at ~600 MHz

We present results from our radio polarimetric study with the upgraded Giant Metrewave Radio Telescope (uGMRT) at Band 4 (550-850 MHz) of 3 blazars: radio-loud quasars 3C390.3, 4C71.07 and BL Lac object 1ES 2344+514. The aim of this study was (i) to carry out a feasibility study for Band 4 polarization with the uGMRT, and (ii) to compare and contrast the kpc-scale polarization properties between the blazar sub-classes. We have detected linear polarization in all the three sources. The degree of linear polarization in the cores of the two quasars is higher than in the BL Lac object, consistent with similar differences observed on parsec-scales in blazars. The highest fractional polarization of 15% is observed in the hotspot region of 3C390.3, which also shows extended polarized lobe structures. 1ES 2344+514 shows a core-halo structure whereas 4C71.07 remains unresolved. A rotation of polarization electric vectors along the northern hotspot of 3C390.3, and the core of 1ES 2344+514, suggest jet bending. Greater depolarization in the southern lobe of 3C390.3 compared to the northern lobe indicates the presence of the `Laing-Garrington effect'. Multi-frequency uGMRT polarimetric data are underway to study the kpc-scale rotation measures across these sources in order to look for differences in the surrounding media.Comment: 13 pages, 6 figures, accepted by Journal of Astrophysics and Astronom

A Kpc-scale Radio Polarization Study of PG BL Lacs with the uGMRT

We present here uGMRT band 4 (~650MHz) polarization images of 8 BL~Lac objects belonging to the Palomar-Green (PG) `blazar' sample. A large fraction of the sources (~63%) reveal core-halo radio structures with most of the polarization detected in the inner core-jet regions. PG1101+385 and PG2254+075 exhibit a `spine-sheath structure' in polarization. The core-halo and `spine-sheath' structures are consistent with the Unified Scheme suggestion that BL~Lacs are the pole-on beamed counterparts of Fanaroff-Riley (FR) type I radio galaxies. PG1418+546 and PG0851+203 (OJ287) show the presence of terminal hotspots similar to FR type II radio galaxies. They were also found to be low-spectrally peaked BL Lacs, supportive of the `blazar envelope' scenario for BL~Lacs and quasars. Fractional polarization ranges from 1-13% in the cores and 2-26% in the inner jets/lobes of the sample BL Lacs. Compared to the varied radio morphology of quasars from the PG `blazar' sample, the BL~Lacs appear to be less diverse. A comparison of the inferred core magnetic (B-) field structures on arcsec- (kpc-) scales w.r.t. the Very Long Baseline Interferometry (VLBI) jet direction does not reveal any preferred orientation, suggesting that if large-scale ordered B-fields exist, they do so on scales smaller than probed by the current observations. However, the presence of polarized emission on arcsec-scales suggests that any mixing of thermal plasma with the synchrotron emitting plasma is insufficient to fully depolarize the emission via the internal depolarization process.Comment: 17 pages; 12 figures; MNRAS accepte

Probing the interplay between jets, winds and multi-phase gas in 11 radio-quiet PG Quasars: A uGMRT-VLA study

We present polarization-sensitive images from the Karl G. Jansky Very Large Array (VLA) at 5 GHz of 11 radio-quiet PG quasars. Based on the radio morphology, spectral index and polarization properties from the VLA study, coupled with the findings of our previous 685 MHz uGMRT data, we find the presence of low-powered jets on sub-arcsecond and arcsecond scales in 9 sources; some show signatures of bent jets. The origin of radio emission remains unclear in the remaining 2 sources. Of the 11 sources, linear polarization is detected in four of them with fractional polarization ranging between 2% and 25%. In PG 1229+204, the inferred B-field direction is parallel to the local kpc-scale jet direction. The inferred B-fields are transverse to the weak southward extension in PG 0934+013. For PG 0050+124 and PG 0923+129, the relationship between the B-field structure and radio outflow direction remains unclear. Localized or small-scale jet-medium interactions can be inferred across the sample based on the VLA jet kinetic power arguments and polarization data. These may have the potential as a feedback mechanism. We find that the radio properties do not show strong correlations with the star formation, [O~III] and CO quantities published in the literature. The lack of evidence of AGN feedback on the global galaxy properties could be due to the relative time scales of AGN activity and those over which any impact might be taking place.Comment: 21 pages, 10 figures; accepted for publication in Ap

Prevalence of Presenting Conditions in Grey Seal Pups (Halichoerus grypus) Admitted for Rehabilitation

A retrospective survey was performed on the presenting conditions of 205 live grey seal pups (Halichoerus grypus) admitted to the Cornish Seal Sanctuary in Gweek, United Kingdom between May 2005 and March 2011. The purpose of the survey was to examine the prevalence of various presenting signs at the sanctuary. The presenting signs were classified into nine non-mutually exclusive categories: ocular disorders, nasal disorders, oral disorders, respiratory disorders, orthopaedic disorders, puncture wounds, abrasions, netting injuries, and onychia. The sex ratio of seal pups in this study was 1.35 males per female. Of the 205 examined for rehabilitation, 22 (10.73%) did not survive to release. 68.78% of grey seal pups presented with puncture wounds, 47.80% with respiratory disorders, 46.34% with ocular disorders, 42.63% malnourished, 36.59% with abrasions, 25.37% with oral disorders, 23.90% with nasal disorders, 11.71% with orthopaedic disorders, 9.27% with onychia, and 3.41% presented with netting injuries. 52% were normothermic, 42% were hyperthermic, and 5% were hypothermic. Associations between gender, outcome of rehabilitation, hospitalisation time and presenting disorders were examined. In addition, admissions rates were found to display seasonality. The results of this study will aid in future preparation of grey seal rehabilitation facilities

Lupus anticoagulant in systemic lupus erythematosus and its association with complications

Background: The anti-phospholipid antibody which can occur secondary to SLE have a broad spectrum of both thrombotic and non-thrombotic manifestations. Among the three antiphospholipid antibodies, lupus anticoagulant has the strongest association with antiphospholipid syndrome (APS) and increased chance of recurrence of thrombotic events. Hence early screening of lupus anticoagulant is needed.Methods: 72 clinically diagnosed SLE patients were included. The PT, aPTT were done in all patients. The clotting time is assessed by semi-automated coagulation analyser by using dilute russell viper venom time (dRVV) screen and confirm kits. Lupus anticoagulant was considered to be positive if the screen to confirm ratio is ≥1.2. The patients were followed up for a period of 1 year at regular 3 months interval. The various complications like hemolytic anemia, thrombocytopenia, deep vein thrombosis, cerebrovascular accident/transient ischemic attack (CVA/TIA), myocardial infarction, abortions, pulmonary artery hypertension and lupus nephritis were recorded.Results: Lupus anticoagulant was positive in 38.8% among the study group. The most common thrombotic event observed was DVT (16.7%) followed by MI (11.1%) and CVA/TIA (8.3%). There is significant association between lupus anticoagulant positivity with hemolytic anemia, DVT and pulmonary artery hypertension.Conclusions: The lupus anticoagulant has the strongest association with APS in SLE patients and dRVVT is the test of choice in diagnosing APLA. Early recognition of APLA can reduce the risk of thrombotic complications and can prevent further episodes by giving adequate thromboprophylaxis to lupus anticoagulant positive patients
