Objectives: Dental or maxillofacial emergencies are uncommon during pregnancy, but if they occur, they are challenging to treat due to potential risks. The mother should not be denied necessary medical or dental care because of pregnancy. The aim of the study is to observe outcomes of pregnancy in patients requiring emergency minor oral surgical procedures during gestation and to determine the safety of the pregnant woman undergoing the procedure and the fetus. Materials and Methods: The study was conducted on 52 pregnant women requiring emergency oral surgical procedures. A standard treatment protocol for treatment of specific entities was followed. Close monitoring and observation were the primary goal of treatment. All patients were followed postoperatively until complete recovery from the surgical procedures and then until birth of the baby. A control group of 52 healthy pregnant patients who did not require oral surgical procedures was considered for statistical analysis. The measurements to calculate observation were fetal loss (spontaneous abortion), preterm birth, low-birth weight, or incidence of any congenital anomalies in the baby and its association with surgical procedures. Results: No fetal loss occurred in any of the cases. However, four patients experienced preterm birth and seven neonates exhibited low birth weights. No congenital abnormalities were discovered. In one instance, a patient who underwent surgery for a mandibular symphysis fracture under general anesthesia in the 31st week of pregnancy experienced labor pain on the fourth postoperative day, requiring an emergency Caesarean section. Conclusion: The results of our study demonstrate that, compared to the control group, minor emergency surgeries performed during pregnancy have no discernible negative effects on the fetus. These procedures can safely be performed by adhering to our described protocols.

<P><B>Abstract</B></P> <P>Solid basic catalysts are extremely useful for green catalytic processes because of their high activity, easy separation, and minimal corrosion. Herein, we report the development and effect of the basicity of five various MgO nanostructures developed by microwave (MW) irradiation in different ionic liquids (ILs) on the Claisen-Schmidt Condensation Reaction. The growth of the shape-controlled MgO nanostructures in the presence of the synergetic effect of the ILs with the MW irradiation developed various basic sites on the surface of the MgO nanocrystals. Due to the synergetic effect (formation of hydrogen bonding and π-π interactions between the ILs and the MgO precursor in the presence of MW irradiation) produced active basic sites in the final nanostructure. The TPD & XPS results show that the synergetic effect strongly altered the percentages of high, low, and moderate basic sites of the catalysts. To determine their catalytic activity based on the obtained different basicity in the MgO nanostructures, prepared all nano structures were tested in the reaction. The altered basicity of the MgO catalysts strongly affected on reaction results and demonstrated better activity than pure MgO. Particularly, hexagonal MgO nanostructures with exposed crystal facets (110) and (111) having high surface area and basicity showed an outstanding activity. In addition, effect or reaction parameters such as temperature, catalyst amount, solvent effect, and reaction time were determine and obtained optimized reaction condition for outstanding results. To determine the diversity of prepared MgO nanostructures, various substituted chalcones were prepared in optimized reaction condition in good to efficient yield. Recyclability of prepared catalyst was also determined up-to 6 cycles and physicochemical changes before and after recyclability test was determined. The proper correlation of obtained basicity & basic sites with the catalytic activity was established with this protocol.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Shape controlled MgO structures were used as catalysts having altered basicity. </LI> <LI> Altered basicity developed by ILs and MW irradiation while structure development. </LI> <LI> Exposed high surface with (110) (111) facets of MgO showed outstanding activity. </LI> <LI> Catalysts can be recycled without disturbing morphology and catalytic activity. </LI> <LI> New green approach for the alteration of basic sites in heterogeneous base catalysts. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>

Highly stable bilayer of LiPON and B₂O₃ added Li_1.5Al_0.5Ge_1.5(PO₄) solid electrolytes for non-aqueous rechargeable Li-O₂ batteries

Jadhav, H.S.,Kalubarme, R.S.,Jadhav, A.H.,Seo, J.G. Pergamon Press 2016 ELECTROCHIMICA ACTA Vol.199 No.-

Lithium ion conducting membranes are barely studied, although they are essentially indispensable for building Li-air batteries composed of aqueous and non-aqueous electrolytes for long-term operation. Lithium phosphorous oxynitride (LiPON) thin films were deposited by RF-sputtering technique on B<SUB>2</SUB>O<SUB>3</SUB>-added lithium aluminum germanium phosphate (B-LAGP). Compact thin amorphous LiPON layer could act as a protective interlayer for B-LAGP by separating it from Li metal electrode and mitigate the reaction between them. Large electrochemical stability window (0-5V) of LiPON/B-LAGP solid electrolyte shows promising feasibility for applications in all lithium based batteries. The aprotic Li-O<SUB>2</SUB> cell with protected lithium electrode configuration employing LiPON/B-LAGP solid electrolyte has exhibited reasonable cycling stability with long-life of 52 cycles at a limited capacity of 1000mAhg<SUP>-1</SUP>.

Sanjeev Jadhav,Sachin Sanagar,Jeenam Shaha,Jayalakshmi Kutty,Mona Jadhav 대한흉부외과학회 2020 Journal of Chest Surgery (J Chest Surg) Vol.53 No.6

Primary tracheobronchial lipoma is an extremely rare entity, the diagnosis of which is often missed initially. Cases are generally diagnosed late after initial treatment for asthma and bronchitis. We report a case of a 42-year-old man with a left main bronchus lipoma that caused near-total obstruction. The lipoma was treated by bronchoscopic resection with an electrosurgical snare and cryoablation.

Biodegradation of Disperse Dye Brown 3REL by Microbial Consortium of Galactomyces geotrichum MTCC 1360 and Bacillus sp. VUS

S. U. Jadhav,U. U. Jadhav,V. V. Dawkar,S. P. Govindwar 한국생물공학회 2008 Biotechnology and Bioprocess Engineering Vol.13 No.2

The consortium-GB (Galactomyces geotrichum MTCC 1360 and Bacillus sp. VUS) exhibited 100% decolorization ability with the dye Brown 3REL within 2 h at shaking condition with optima of pH 7 and at 50℃. However, G. geotrichum MTCC 1360 showed 39% decolorization within 24 h and Bacillus sp. VUS took 5 h for 100% decolorization, when incubated individually. Additional carbon and nitrogen sources like, starch, peptone, and urea were found to enhance decolorization. Induction in lignin peroxidase, tyrosinase, and riboflavin reductase was observed in consortium as that of individual organisms. GCMS identification showed different metabolites formed using consortium (2-(6,8-dichloro-quinazolin-4yloxy)-acetyl-urea and 2-(6,8-dichloro-quinazolin-4yloxy)-acetyl-formamide) and Bacillus sp. VUS (6,8-dichloro-4 methoxy-quinazoline) after 2 h of incubation with Brown 3REL. G. geotrichum MTCC 1360 showed minor modifications in structure of Brown 3REL. Phytotoxicity revealed non toxic nature of metabolites. This consortium-GB was also able to decolorize various industrial dyes.

Akash Sitaram Jadhav,Madhukar Vinayak Jadhav 한국화학공학회 2021 Korean Journal of Chemical Engineering Vol.38 No.10

Fluoride removal systems have been established to curb the health hazards from fluoride. However, these techniques are not feasible in rural communities. Therefore, use of agricultural wastes as adsorbing material for fluoride removal can be fruitful to rural areas. A study of the influence of constraints like pH, adsorbent dosage, contact period and stirring rate on efficiency of fluoride removal was conducted using ash obtained from black mustard husk as an adsorptive material. Batch study was carried out to study the efficiency of the adsorbent for defluoridation. Removal efficiency of up to 84 percent was observed for the fluoride uptake using black mustard husk fly ash (BMHFA). Adsorbent dosage of 2 g, pH value of 2, contact time of 150 min and stirring rate of 200 rpm were found to be the optimum process parameter values. Adsorption models like Freundlich, Temkin and Langmuir models were used to validate the results. Langmuir model was seen best fitting with the results having an R2 value equal to 0.96 and indicating a homogeneous monolayer surface assimilation. Pseudo-first-order kinetics, pseudo-second-order kinetic modelling and intra-particle diffusion were studied. The kinetic models showed the prominent influence of physisorption in the adsorption process. A thermodynamic study of the adsorption phenomenon was conducted and it was found that the nature of sorption process was spontaneous and endothermic. The adsorbent was characterized using X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). The adsorbent was found to be efficient in fluoride sorption when tested on real water samples. Regeneration study showed good reusability of the spent adsorbent. This study provides a good prospective and stimulating work for the researchers working in this field.

Enhanced electrochemical performance of flower-like Co₃O₄ as an anode material for high performance lithium-ion batteries

Jadhav, H.S.,Rai, A.K.,Lee, J.Y.,Kim, J.,Park, C.J. Pergamon Press 2014 ELECTROCHIMICA ACTA Vol.146 No.-

A facile urea-assisted template-free, surfactant-less chemical co-precipitation method was used to obtain a flower-like cobalt oxide sample followed by annealing at various temperatures of 400, 500, and 600<SUP>o</SUP>C for 2h. The obtained flower-like morphology was assembled by nanorods, and the nanorods were comprised of interconnected particles with a porous structure. The changes in the surface area of the obtained flower-like Co<SUB>3</SUB>O<SUB>4</SUB> samples were systematically examined at various temperatures and their impact on the electrochemical performances was observed. Electrochemical investigation showed that the flower-like Co<SUB>3</SUB>O<SUB>4</SUB> samples obtained at 500<SUP>o</SUP>C, showed excellent cycling stability (1536.9mAhg<SUP>-1</SUP> at 0.1C up to 50 cycles and 1226.9mA h g<SUP>-1</SUP> at 0.5C up to 350 cycles) and superior rate capability (845mAhg<SUP>-1</SUP> at 10C). It is believed that the porous nature of the unique structure facilitates the penetration of the electrolyte at the electrode/electrolyte interface and provides a large space for strain buffering, which ultimately allows the present sample to achieve high rate performances.

Jadhav, Harsharaj S.,Kalubarme, Ramchandra S.,Roh, Jang-Woong,Jung, Kyu-Nam,Shin, Kyoung-Hee,Park, Choong-Nyeon,Park, Chan-Jin The Electrochemical Society 2014 Journal of the Electrochemical Society Vol.161 No.14

<P>The electrochemical performance of lithium-oxygen batteries can be significantly improved by employing a suitable catalyst to enhance the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER). Herein, a versatile, effective and economic co-precipitation synthesis of spinel NiCo<SUB>2</SUB>O<SUB>4</SUB> with an urchin-like structure has been reported as an electrocatalyst for rechargeable non-aqueous Li-O<SUB>2</SUB> batteries. The spherical urchin-like structure of spinel NiCo<SUB>2</SUB>O<SUB>4</SUB> was formed without the use of any template or surfactant. The oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) kinetics in the Li-O<SUB>2</SUB> batteries could be drastically improved by employing the effective NiCo<SUB>2</SUB>O<SUB>4</SUB> catalyst, achieving a higher discharge potential and rate. In particular, the urchin-like structure of the catalyst not only provides more electrocatalytic sites but also promotes mass transport in the electrolyte. In addition, mesoporous NiCo<SUB>2</SUB>O<SUB>4</SUB> can efficiently catalyze the formation and decomposition of Li<SUB>2</SUB>O<SUB>2</SUB>. The Li-O<SUB>2</SUB> battery containing the urchin-like NiCo<SUB>2</SUB>O<SUB>4</SUB> catalyst exhibited the highest specific capacity of about 7309 mA h g<SUP>−1</SUP> at 0.2 mA cm<SUP>−2</SUP>. The integrity and porosity of spinel NiCo<SUB>2</SUB>O<SUB>4</SUB> had a significant effect on the performance of the Li-O<SUB>2</SUB> battery with reasonable specific capacity and cyclability, suggesting that the NiCo<SUB>2</SUB>O<SUB>4</SUB>-based materials can be effective catalysts for oxygen electrode in high performance Li-O<SUB>2</SUB> batteries.</P>

Jadhav, Vinod H.,Jeong, Hwan-Jeong,Lim, Seok Tae,Sohn, Myung-Hee,Song, Choong Eui,Kim, Dong Wook Elsevier 2013 Tetrahedron Vol.69 No.17

<P><B>Abstract</B></P> <P>We investigated various structurally modified polystyrene-supported oligoethylene glycols (PSoligoEG) in order to find an optimized PSoligoEG by examining the dependence of their catalytic activity on the oligoethylene glycol chain length and the loading level of the oligoethylene glycol portion on the polystyrene support. From this, we found that the PSpentaEG with the highest pentaEG loading had the best catalytic efficacy among the various PSoligoEGs in nucleophilic substitutions. This PSpentaEG absorbed both polar aprotic solvents, such as DMSO, DMF, and acetonitrile, as well as protic media, such as <I>tert</I>-amyl alcohol and aqueous acetone, and swelled considerably. To expand the scope of the PSpentaEG as a heterogeneous catalyst for diverse nucleophilic displacement reactions, we carried out the thioacetoxylation, nitrilation, azidation, iodination, bromination, chlorination, and methoxylation using the corresponding alkali metal salts in the presence of PSpentaEG in various solvents; all the reactions proceeded smoothly, affording the corresponding products in high yields.</P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
