Centrifugal technique of plasma exchange and low-dose steroid to treat very severe alcoholic hepatitis patients: A retrospective analysis.

Background: Low-volume plasma exchange (PLEX) and low-dose steroid improve survival in severe alcoholic hepatitis. We aimed to compare one-year survival of very severe alcoholic hepatitis (VSAH) patients treated with centrifugal PLEX (cPLEX), membrane PLEX (mPLEX) or standard medical treatment (SMT).

Methods: We retrospectively analyzed survival in consecutive VSAH patients treated at our department from November 2017 to September 2021.

Single-Centre Experience With Low-Volume Plasma Exchange and Low-Dose Steroid to Treat Patients With Idiosyncratic Drug-Induced Acute Liver Failure.

Background: Idiosyncratic drug-induced liver injury (iDILI) causing acute liver failure (ALF) carries high short-term mortality and patients who meet King's College criteria for liver transplantation have 1-month survival of 34% without liver transplantation (PMID: 20949552). We present our experience with low-volume plasma exchange (PLEX-LV, 50% of estimated plasma volume exchanged per session) and low-dose steroid to treat iDILI ALF.

Methods: We retrospectively analysed data of patients with iDILI (diagnosed as per RUCAM score), treated with PLEX-LV and low-dose steroid (prednisolone: 10 mg OD, with rapid taper) in our department from 2016 to 2022.

Suspended Particulate Matter Analysis of Pre and During Covid Lockdown Using Google Earth Engine Cloud Computing: A Case Study of Ukai Reservoir.

Presence of suspended particulate matter (SPM) in a waterbody or a river can be caused by multiple parameters such as other pollutants by the discharge of poorly maintained sewage, siltation, sedimentation, flood and even bacteria. In this study, remote sensing techniques were used to understand the effects of pandemic-induced lockdown on the SPM concentration in the lower Tapi reservoir or Ukai reservoir. The estimation was done using Landsat-8 OLI (Operational Land Imager) having radiometric resolution (12-bit) and a spatial resolution of 30 m.

Structural functional and folding scenario of an anti platelet and thrombolytic enzyme crinumin.

A folding pattern, conformational stability and therapeutic role of a protein helps in developing a suitable drug. Crinumin, a thrombolytic and anti platelet agent, has been studied for its functional and conformational properties by equilibrium unfolding methods. The crinumin belongs to α+β class of protein and exhibits a non native structure and two molten globule states at different conditions.

Crystallization and preliminary X-ray analysis of crinumin, a chymotrypsin-like glycosylated serine protease with thrombolytic and antiplatelet activity.

Crinumin, a novel glycosylated serine protease with chymotrypsin-like catalytic specificity, was purified from the medicinally important plant Crinum asiaticum. Crinumin is a 67.7 kDa protease with an extraordinary stability and activity over a wide range of pH and temperature and is functional in aqueous, organic and chaotropic solutions.

Seasonal trends of PM2.5 and PM10 in ambient air and their correlation in ambient air of Lucknow city, India.

The PM(10) concentration (μg/m(3)) in Lucknow city at 4 locations in three different seasons ranged between 148.6-210.8 (avg.

Thrombolytic along with anti-platelet activity of crinumin, a protein constituent of Crinum asiaticum.

Several anticoagulants, anti-platelet and thrombolytic medications are used for the treatment of thrombotic disorders. Anti-coagulants and anti-platelet agents prevent the formation of blood clots but do not dissolve existing clots, whereas thrombolytic agents are able to dissolve a clot but emboli can form even after successful treatment. Thus, none of them provide a permanent and complete solution.

Biochemical and spectroscopic characterization of a novel metalloprotease, cotinifolin from an antiviral plant shrub: Euphorbia cotinifolia.

A high molecular mass novel metalloprotease, cotinifolin is purified from the latex of Euphorbia cotinifolia by a combination of anion exchange and hydrophobic interaction chromatography. The nonglycosylated enzyme has a molecular mass of 79.76 kDa (ESI-MS) and the isoelectric point of the enzyme is pH 7.

Synthesis and anti-implantation activity of new stilbene derivatives.

New stilbene (CAS 56-53-1) derivatives have been synthesized by reductive elimination of desoxybenzoin analogs which were obtained by Fries rearrangement of the corresponding phenolic esters. The chemical structures of the compounds obtained were confirmed by 1H-NMR, IR and elemental analysis. Anti-implantation activity of the compounds was determined by performing experiments with adult male and female Spargue-Dawley rats of proven fertility.

Chemo- and stereoselective synthesis of benzocycloheptene and 1-benzoxepin derivatives as alpha-sympathomimetic and anorexigenic agents.

The synthesis and pharmacological evaluation of cis- and trans-6-amino-6,7,8,9-tetrahydro-5H-benzocyclohepten-5-ols 4a-c and 5a-c and cis- and trans-4-amino-2,3,4,5-tetrahydro-1-benzoxepin-5-ols 4d-f and 5d-f were carried out. Chemo- and stereoselective synthesis of 5a-f was achieved by reduction of corresponding alpha-amino ketones 3a-f with LiAl(t-BuO)3H. cis-4-Amino-2,3,4,5-tetrahydro-1-benzoxepin-5-ol 4d and trans-4-amino-2,3,4,5-tetrahydro-1-benzoxepin-5-ol 5d exhibited marked anorexigenic activity in mice at a dose of LD50 800 and 500 mg/kg and ED50 75 and 55 mg/kg, respectively, while the analog cis-2,3-dihydroxy-6-amino-6,7,8,9-tetrahydro-5H-benzocyclohepten-5-ol 8 showed typical alpha-sympathomimetic activity.

1- and 2-substituted naphthalenes: a new class of potential hypotensive agents.

A series of 2-substituted aminomethyloxy naphthalenes 1 and 4-(1-naphthoxy-2-substituted aminomethyl)-butanoic acids 2 were synthesized by Mannich reaction of 4-(2-naphthoxy)-butanoic acid 3 and 4-(1-naphthoxy)-butanoic acid 4 with appropriate secondary amines and para-formaldehyde.
