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>

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>.

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.

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.

A tailor-made di-cationic ionic liquid (DCIL), hexaethylene glycol (hexaEG) bridged bis(2-hydroxy-2-methyl-n-propylimidazolium) dimesylate (hexaEG-D<SUP>t</SUP>OHIM), was prepared in 94% yield. We investigated the catalytic activity of hexaEG-D<SUP>t</SUP>OHIM and hexaEG-bridged bis(3-hexaEGyl imidazolium) dimesylate (hexaEG-DHIM) in nucleophilic fluorination using an alkali metal fluoride (MF) and compared their activities with a variety of mono-cationic ILs. In this reaction, these two task-specific DCILs exhibited much higher catalytic activity than mono-cationic ILs. Moreover, the hexaEG functionalized IL (e.g. hexaEG-DHIM) more effectively enhanced the reactivity of KF compared with the t-alcohol functionalized IL (e.g. hexaEG-D<SUP>t</SUP>OHIM). In particular, the combination of KF/hexaEG-DHIM in t-alcohol media provided excellent chemoselectivity and high chemical yields in the fluorination reaction of base sensitive substrates such as 1-(2-mesyloxyethyl)naphthalene. This protocol was shown to be generally applicable to fluorination reactions with a variety of substrates.

An osteolytic lesion with a small central area of mineralization and sclerotic borders was discovered incidentally in the clivus on the cone-beam computed tomography (CBCT) of a 27-year-old male patient. This benign appearance indicated a primary differential diagnosis of non-aggressive lesions such as fibro-osseous lesions and arrested pneumatization. Further, on magnetic resonance imaging (MRI), the lesion showed a homogenously low T1 signal intensity with mild internal enhancement after post-gadolinium and a heterogeneous T2 signal intensity. These signal characteristics might be attributed to the fibrous tissues, chondroid matrix, calcific material, or cystic component of the lesion; thus, chondroblastoma and chondromyxoid fibroma were added to the differential diagnosis. Although this report was limited by the lack of final diagnosis and the patient lost to follow-up, the incidental skull base finding would be important for interpreting the entire volume of CBCT by a qualified oral and maxillofacial radiologist.

<P><B>Abstract</B></P><P>A hydrophobic and water-insoluble platinum(II) compound, <I>cis</I>-(cha)<SUB>2</SUB>Pt(NO<SUB>3</SUB>)<SUB>2</SUB> was encapsulated by macromolecular micelles self-assembled from an amphiphilic cyclotriphosphazene [NP(MPEG750)(GlyPheLeu)<SUB>2</SUB>Et]<SUB>3</SUB> (CP750). The micelle-encapsulated platinum(II) compound exhibited outstanding pharmacokinetics in rats by showing long blood circulation and much larger systemic exposure (AUC=43.5μgh/ml) compared with the free carboplatin (AUC=4.32μgh/ml). Biodistribution study of the micellar platinum(II) compound using male Sprague–Dawley rats has shown excellent tumor to tissue ratios of 4.03 at 2h post injection and 4.67 at 24h post injection. Furthermore, the micellar platinum(II) compound exhibited more than 6 times higher cellular uptake in human cervical (HeLa) and lung (A549) tumor cells compared with the free platinum compound. Also it is surprising that the micellar platinum(II) compound displayed specifically high cytotoxicity against the stomach tumor cells (SNU638), which are one of the least responsive to chemotherapeutic agents currently in clinical use. The acute toxicity study has shown that the LD<SUB>50</SUB> values of free and the micellar <I>cis</I>-(cha)<SUB>2</SUB>Pt(NO<SUB>3</SUB>)<SUB>2</SUB> are approximately 70mg/kg and 90mg/kg, respectively.
