CLINICAL STUDY ON CHURNA BASTI ADMINISTERED IN MODIFIED KALA BASTI SCHEDULE IN AMAVATA

Amavata is most common debilitating joint disorder which makes the life of patient almost crippled. Amavata in the modern parlance can be correlated with Rheumatoid Arthritis which is a highly prevalent disease in the present life scenario due to the changing dietetic habits, social structure, environmental and mental stress. Ayurveda has a lot to offer in this regard. The Chikitsa explained for Amavata includes Shodhana as well as Shamana which includes Langhana, Deepana, Swedana, Virechana, Snehapana, Basti and Upanaha. Therefore, the study was planned to evaluate the efficacy of Churnabasti in modified Kalabasti schedule in the management of Amavata. Churna Basti yoga explained by Acharya Chakrapani comprises of drugs possessing Ushna & Teekshnagunas, Deepana-Pachana, Vata Kaphahara and Shula-Shothahara properties which may help in attaining Agnideepti, Laghutva, Nirama Lakshana and Shoolahara effect. Combination of Vaishwanara choorna, Rasna Saptaka Kashaya and Dhanyamla administered in Amavata is yielding beneficial effects as the ingredients possess the properties opposite to that of Amavata and therefore acts positively on the disease. The present study was planned based on this concept and statistically highly significant effects (P>0.0001) were observed in the various assessment parameters of Amavata such as Sandhishoola, Sandhishotha, Sandhistabdhata Sandhisparsa Asahyata etc. In overall effect of therapy maximum number of patients (40.12%) got marked improvement. Therefore, Churna Basti comprising of drugs possessing properties opposite to Ama can be considered as a good remedy in the management of Amavata

Functional outcomes following various reconstructive methods following various forms of maxillectomies- a tertiary centre experience

Background: The maxilla is the pivotal structure of the midface, separating the oral, antral, and orbital cavities, and providing support to the globes, lower eyelids, cheeks, lips, and nose. In addition, the maxilla play a critical role in speech, swallowing, and mastication. To evaluate the functional outcomes following various reconstructive methods following various forms of maxillectomiesMethods: Retrospective analysis of medical records of patients who underwent various forms of maxillectomies from January 2011 to December 2013. Postmaxillectomy defects were managed by either prosthesis or local flaps.Results: Forty patients had various forms of maxillectomies. Fifteen patients had Browns class 1 maxilectomy and all of these patients underwent reconstruction with Pectoralis major myocutaneous flap. Ten patients underwent class 2a maxillectomy and reconstruction with obturator and Split skin thickness grafting. Nine patients underwent class 3a-b resection and four patients class 4a-b resection and all had reconstruction with temporalis myofascial flap. Two patients underwent orbitomaxillary resection with palate preserved and reconstruction with temporalis myofascial and forehead flap. Mean follow up period was 8 months (Range 6- 24 months). Two patients developed moderate grade of trismus after completion of radiotherapy.  One patient developed recurrence in neck after 6 months of completion of adjuvant radiotherapy. All had moderate to fair speech and eating function which improved over time.Conclusions: There was no difference between flap reconstruction or obturator intervention of maxillary defects in speech and eating function. Small and lateral defects are better reconstructed with obturator and defects involving orbit and total maxilla are better reconstructed with regional flaps. Hence even in the era of microvascular flaps, obturator and regional flaps can still be considered for reconstruction of maxillectomy defects with fairly good outcome

Comparison of short-term outcomes following open and laparoscopic resections for colorectal malignancies

Background: The laparoscopic approach for colorectal cancers are still a matter of controversy. In the present study, we tried to compare the laparoscopy with open methods of colorectal resections.Methods: Retrospective study where patients diagnosed with colorectal cancer in our hospital from year 2014 January to December 2016 were taken. Total number of cases were 69 of which, the total number of right colon cases were 26. Out of twenty-six, 12 underwent open procedure and 14 underwent laparoscopic resections. Total number of left colon cancers were 09. Of these, 2 underwent open and 7 underwent laparoscopic procedure. Thirty-four (34) rectal cancers were included in the study. Of these, 12 underwent open rectal procedures and 22 underwent laparoscopic resections. Multiple parameters like duration of surgery, post-operative complications, postoperative stay, pathological T staging, lymph node yield, positive nodes, distal resection margins, circumferential radial margins were compared.Results: Operating time was significantly shorter in open procedure than laparoscopic surgery in both rectal resection and right hemicolectomies. The postoperative stay was significantly shorter in laparoscopic right hemicolectomy compared to open procedure. All other parameters like post-operative complications, T stage, lymph node yield, positive nodes, distal resection margins and CRMs were comparable in both groups. The lymph node yield was similar in upfront and post neoadjuvant carcinoma rectum cases.Conclusions: Laparoscopic colorectal resections have similar rates of complication, with shorter hospital stays with no compromise on oncological clearance with respect to lymph node yield, CRMs, distal resection margins compared to open procedures

TCSC-STATCOM Controller for the Voltage Stability Improvement of the Wind Farm Connected to the Grid

The project is about the improvement of voltage stability of the system which has a wind farm connected to the Grid. A combination of TCSC and STATCOM is used in the controller. The controller ensures that the system receives enough reactive power to maintain stability. The simulation model is going to be inbuilt MATLAB/SIMULINK. output voltages of the system without the controller, with each component acting separately and the collaborative control effect of TCSC and STATCOM, will be compared and studied in the simulated model to prove the efficiency of the controller

Electroactive Covalent Organic Framework Enabling Photostimulus-Responsive Devices

Two-dimensional covalent organic frameworks (2D COFs) feature graphene-type 2D layered sheets but with a tunable structure, electroactivity, and high porosity. If these traits are well-combined, then 2D COFs can be applied in electronics to realize functions with a high degree of complexity. Here, a highly crystalline electroactive COF, BDFamide-Tp, was designed and synthesized. It shows regularly distributed pores with a width of 1.35 nm. Smooth and successive films of such a COF were fabricated and found to be able to increase the conductivity of an organic semiconductor by 103 by interfacial doping. Upon encapsulation of a photoswitchable molecule (spiropyran) into the voids of the COF layer, the resulted devices respond differently to light of different wavelengths. Specifically, the current output ratio after UV vs Vis illumination reaches 100 times, thus effectively creating on and off states. The respective positive and negative feedbacks are memorized by the device and can be reprogrammed by UV/Vis illumination. The reversible photostimulus responsivity and reliable memory of the device are derived from the combination of electroactivity and porosity of the 2D COF. This work shows the capability of 2D COFs in higher-level electronic functions and extends their possible applications in information storage

JAK2/IDH-mutant–driven myeloproliferative neoplasm is sensitive to combined targeted inhibition

Patients with myeloproliferative neoplasms (MPNs) frequently progress to bone marrow failure or acute myeloid leukemia (AML), and mutations in epigenetic regulators such as the metabolic enzyme isocitrate dehydrogenase (IDH) are associated with poor outcomes. Here, we showed that combined expression of Jak2V617Fand mutant IDH1R132Hor Idh2R140Q induces MPN progression, alters stem/progenitor cell function, and impairs differentiation in mice. Jak2V617FIdh2R140Q–mutant MPNs were sensitive to small-molecule inhibition of IDH. Combined inhibition of JAK2 and IDH2 normalized the stem and progenitor cell compartments in the murine model and reduced disease burden to a greater extent than was seen with JAK inhibition alone. In addition, combined JAK2 and IDH2 inhibitor treatment also reversed aberrant gene expression in MPN stem cells and reversed the metabolite perturbations induced by concurrent JAK2 and IDH2 mutations. Combined JAK2 and IDH2 inhibitor therapy also showed cooperative efficacy in cells from MPN patients with both JAK2mutand IDH2mutmutations. Taken together, these data suggest that combined JAK and IDH inhibition May offer a therapeutic advantage in this high-risk MPN subtype.Damon Runyon Cancer Research Foundation (DRG-2241-15)Howard Hughes Medical Institute (Faculty Scholars Award)Stand Up To CancerNational Cancer Institute (U.S.) (P50CA165962)National Cancer Institute (U.S.) (P30CA14051)Koch Institute for Integrative Cancer Research ( Dana-Farber Harvard Cancer Center Bridge Project)Leukemia & Lymphoma Society of America.
