Synthesis and Antimicrobial Evaluation of Novel Carbazole Based β-diketones and its Pyrazole Derivatives
Novel 9-ethyl-9H-carbazole-3-carboxylic acid derivatives including ester, β-diketone and pyrazole were prepared and characterized by FT-IR, 1H NMR, 13C NMR and mass spectroscopic techniques. All synthesized compounds evaluated for their in vitro antimicrobial activities against four bacteria (Escherichia coli, Pseudomonas putide, Bacillus subtilis, and Streptococcus lactis) and three fungi (Aspergillus niger, Penicillium sp and Candida albicans). Among the compounds tested, 3a, 3b, 3c, 4a, 4b, 4c, 5a and 5b exhibited pronounced antibacterial activity as compared with standard drug ampicillin. Notably, carbazole based pyrazole derivatives 5a and 5b showed potent antifungal activity against C. albicans comparable to reference drug greseofulvin.

Conventional laparotomy for management of caesarean scar ectopic pregnancy: a case report
Increase in the rates of caesarean deliveries has led to a concurrent rise in the number of caesarean scar ectopic pregnancies (CSEP). With recent advances, diagnosis can be made at an early gestational age, hence facilitating a prompt intervention. With the varied treatment options available, choosing the right one may possess a clinical dilemma. However, in a low resource setting, conventional laparotomy may be the only option feasible. A case of CSEP managed with laparotomy is presented
Inhibition Planktonic and Bio film Growth of Candida Albicans by Plant Extract Alone and in combination with Fluconazole
This study was to evaluate the efficacy of Methanolic extract of G. superba L in combination with Fluconazole against biofilm development and mature biofilms of C. albicans. Synergism between MEGS and Fluconazole combination against biofilm formation was evident with FICI of 0.187. Combination of MEGS and Fluconazole did not have synergistic potential against mature biofilm growth, evidenced in FICI of 0.916. MIC of standard Fluconazole was found to be 0.5 and >0.5 in biofilm development and mature biofilm respectively
Pregnancy with super-obesity: an emerging pandemic
Pregnancy associated with obesity is an upcoming challenge in high risk obstetrics management. Ironically, in India though half the population is under the malnutrition zone, it is known as the diabetic capital. This is attributed to the changing lifestyles which have led to a steep rise in medical disorders like hypertension, diabetes and obesity, especially in metropolitan cities. A case of pregnancy in a super obese woman with a successful outcome is presented here
Design, synthesis and characterization of novel fluorinated styryl chromones
225-228(E)-3-(3-(Trifluoromethyl)-5-nitrophenyl)acrylic acid 1 when treated with substituted 2-hydroxyacetophenones 2 in dry pyridine and POCl3 affords compound 3 which when reacted with pyridine/KOH by B. V. transformation gives 4. Compound 4 on refluxing with acetic acid in HCl gives 5. The structures of all synthesized compounds have been confirmed by spectroscopic techniques
Late pregnancy vitamin D deficiency is associated with doubled odds of birth asphyxia and emergency caesarean section: A prospective cohort study
Objectives: The aim of this prospective cohort study was to investigate the associations between maternal vitamin D status in late pregnancy and emergency caesarean section (EMCS) and birth asphyxia, in a population based sample of women in Sweden. Methods: Pregnant women were recruited at the antenatal care in Sweden and 1832 women were included after exclusion of miscarriages, terminated pregnancies and missing data on vitamin D status. Mode of delivery was retrieved from medical records. EMCS was defined as caesarean section after onset of labour. Birth asphyxia was defined as either 5 min Apgar score < 7 or arterial umbilical cord pH < 7.1. Serum was sampled in the third trimester of pregnancy (T3) and 25-hydroxyvitamin D (25OHD) was analysed by liquid chromatography tandem mass spectrometry. Vitamin D deficiency was defined as 25OHD < 30 nmol/L, and associations were studied using logistic regression analysis and expressed as adjusted odds ratios (AOR). Results: In total, 141 (7.7%) women had an EMCS and 58 (3.2%) children were born with birth asphyxia. Vitamin D deficiency was only associated with higher odds of EMCS in women without epidural anaesthesia (AOR = 2.01, p = 0.044). Vitamin D deficiency was also associated with higher odds of birth asphyxia (AOR = 2.22, p = 0.044). Conclusions for Practice: In this Swedish prospective population-based cohort study, vitamin D deficiency in late pregnancy was associated with doubled odds of birth asphyxia and with EMCS in deliveries not aided by epidural anaesthesia. Prevention of vitamin D deficiency among pregnant women may reduce the incidence of EMCS and birth asphyxia. The mechanism behind the findings require further investigation

An integrated bioinformatics analysis reveals divergent evolutionary pattern of oil biosynthesis in high- and low-oil plants
Seed oils provide a renewable source of food, biofuel and industrial raw materials that is important for humans. Although many genes and pathways for acyl-lipid metabolism have been identified, little is known about whether there is a specific mechanism for high-oil content in high-oil plants. Based on the distinct differences in seed oil content between four high-oil dicots (20~50%) and three low-oil grasses (<3%), comparative genome, transcriptome and differential expression analyses were used to investigate this mechanism. Among 4,051 dicot-specific soybean genes identified from 252,443 genes in the seven species, 54 genes were shown to directly participate in acyl-lipid metabolism, and 93 genes were found to be associated with acyl-lipid metabolism. Among the 93 dicot-specific genes, 42 and 27 genes, including CBM20-like SBDs and GPT2, participate in carbohydrate degradation and transport, respectively. 40 genes highly up-regulated during seed oil rapid accumulation period are mainly involved in initial fatty acid synthesis, triacylglyceride assembly and oil-body formation, for example, ACCase, PP, DGAT1, PDAT1, OLEs and STEROs, which were also found to be differentially expressed between high- and low-oil soybean accessions. Phylogenetic analysis revealed distinct differences of oleosin in patterns of gene duplication and loss between high-oil dicots and low-oil grasses. In addition, seed-specific GmGRF5, ABI5 and GmTZF4 were predicted to be candidate regulators in seed oil accumulation. This study facilitates future research on lipid biosynthesis and potential genetic improvement of seed oil content
