Evaluation of Plant Growth-Promoting and Salinity Ameliorating Potential of Halophilic Bacteria Isolated From Saline Soil.

Among the biotic and abiotic stress affecting the physical, chemical, and biological properties of soil, salinity is a major threat that leads to the desertification of cultivable land throughout the world. The existence of diverse and versatile microbial populations inhabiting the nutrient-rich soil and varied soil conditions affects the soil dynamism. A normal soil constitutes 600 million bacteria belonging to about 20,000 species, which is reduced to 1 million with 5,000-8,000 species in stress conditions. Plant growth-promoting rhizobacteria (PGPR) are in symbiotic association with the plant system, which helps in combating the abiotic stress and increases the overall productivity and yield. These microorganisms are actively associated with varied cellular communication processes through quorum sensing and secondary metabolites such as the production of Indole-3-acetic acid (IAA), exopolysaccharide (EPS) siderophore, ammonia, ACC deaminase, and solubilization of phosphate. The present study focused on the isolation, identification, and characterization of the microorganisms isolated from the seacoast of Dandi, Navsari. Twelve isolates exhibited PGP traits at a high salt concentration of 15-20%. AD9 isolate identified as Bacillus halotolerans showed a higher ammonia production (88 ± 1.73 µg/mL) and phosphate solubilization (86 ± 3.06 µg/mL) at 15% salt concentration, while AD32* (Bacillus sp. clone ADCNO) gave 42.67 ±1.20 µg/mL IAA production at 20% salt concentration. AD2 (Streptomyces sp. clone ADCNB) and AD26 (Achromobacter sp. clone ADCNI) showed ACC deaminase activity of 0.61 ± 0.12 and 0.60 ± 0.04 nM α-ketobutyrate/mg protein/h, respectively. AD32 (Bacillus sp. clone ADCNL) gave a high siderophore activity of 65.40 ± 1.65%. These isolates produced salinity ameliorating traits, total antioxidant activities, and antioxidant enzymes viz. superoxide dismutase (SOD), Glutathione oxidase (GSH), and catalase (CAT). Inoculation of the multipotent isolate that produced PGP traits and salinity ameliorating metabolites promoted the plant growth and development in rice under salinity stress conditions. These results in 50% more root length, 25.00% more plant dry weight, and 41% more tillers compared to its control.

Nanoparticles combined with cefixime as an effective synergistic strategy against Salmonella enterica typhi.

Enteric fever caused by Salmonella typhi has been the most crucial health issue in rural people, especially in Southeast Asia and Africa. Another disease, Salmonellosis, caused by a large group of bacteria of the genus Salmonella, cause substantial economic loss resulting from mortality and morbidity. Higher concentration and repeated use of antibiotics to treat these diseases will likely develop antibiotic resistance among the microbes. The nanoparticle has good penetration power and can kill microbes. Combining two strategies by using nanoparticles with antibiotics kills microbes and reduces the chances of the development of antibiotics resistance. Silver, Nickel, Copper, and Zinc oxide Nanoparticles were chemically synthesized and characterized in this study. Silver nanoparticles at a concentration of 10 µg/ml inhibit all the strains under study. In comparison, silver nanoparticles (16.90 µg/ml), Nickel nanoparticles (83 µg ml-1), Copper nanoparticles (249 µg ml-1), and Zinc oxide (1614 µg ml-1) along with 50 µg/ml cefixime gave maximum zone of inhibition of 35 mm, 19 mm, 31 mm and 23 mm respectively. The antimicrobial assay showed that silver nanoparticles presented good antibacterial performance against all multi-drug-resistant pathogenic Salmonella sp alone as well as in combinations. The present study proved that silver nanoparticles at the lowest concentration along with cefixime could be a possible alternative to control the multi-drug-resistant pathogens.

Patient-initiated follow-up for low-risk endometrial cancer: a cost-analysis evaluation.

OBJECTIVE: Risk stratification has resulted in patient-initiated follow-up being introduced for low-risk endometrial cancer in place of routine hospital follow-up. The financial benefit to the patient and the healthcare economy of patient-initiated follow-up, as compared with hospital follow-up, has yet to be explored. In this study, we explored the potential impact for both the healthcare economy and patients of patient-initiated follow-up. METHODS: Women diagnosed with low-risk endometrial cancer enrolled on a patient-initiated follow-up scheme between November 2014 and September 2018 were included. Data on the number of telephone calls to the nurse specialists and clinic appointments attended were collected prospectively. The number of clinic appointments that would have taken place if the patient had continued on hospital follow-up, rather than starting on patient-initiated follow-up, was calculated and costs determined using standard National Health Service (NHS) reference costs. The time/distance traveled by patients from their home address to the hospital clinic was calculated and used to determine patient-related costs. RESULTS: A total of 187 patients with a median of 37 (range 2-62) months follow-up after primary surgery were enrolled on the scheme. In total, the cohort were scheduled to attend 1673 appointments with hospital follow-up, whereas they only attended 69 clinic appointments and made 107 telephone contacts with patient-initiated follow-up. There was a 93.5% reduction in costs from a projected £194 068.00 for hospital follow-up to £12 676.33 for patient-initiated follow-up. The mean patient-related costs were reduced by 95.6% with patient-initiated follow-up. The total mileage traveled by patients for hospital follow-up was 30 891.4 miles, which was associated with a mean traveling time per patient of 7.41 hours and clinic/waiting time of 7.5 hours compared with 1165.8 miles and 0.46 hours and 0.5 hours, respectively, for patient-initiated follow-up. CONCLUSION: The introduction of a patient self-management follow-up scheme for low-risk endometrial cancer was associated with financial/time saving to both the patient and the healthcare economy as compared with hospital follow-up.

Acceptability and utilisation of patient-initiated follow-up for endometrial cancer amongst women from diverse ethnic and social backgrounds: A mixed methods study.

INTRODUCTION: A shift in focus towards risk stratification and survivorship in early stage endometrial cancer (EC) has led to the replacement of hospital follow-up (HFU) with patient-initiated follow-up (PIFU) schemes. METHODS: A mixed methods study was undertaken prospectively to investigate utility and patient satisfaction with a newly introduced PIFU scheme. RESULTS: Two hundred and twenty-eight women were enrolled onto PIFU in the first 18 months, median age 65 years (range 42-90 years). Twenty-four (10.5%) women were non-British White ethnicity. Forty-five women contacted the Clinical Nurse Specialist (CNS) at least once (19.7%), the primary reason being vaginal bleeding/discharge (42%). Contact was greater in first six months on the scheme compared to the second 6 months, and women who made contact were significantly younger than those who did not (57 years vs. 65 years, p < 0.001). CONCLUSIONS: PIFU appears to be well received by the majority of women. Although many of the CNS contacts were due to physical symptoms, a number were for psychological support or reassurance. Younger women had greater CNS contact indicating that they may benefit from a greater level support. Patient feedback of the PIFU scheme was positive, with many women reporting that it enabled them to have more control over their own health.

Parent-child interactions in pediatric bipolar disorder.

Parent-child relationships may have a significant effect on illness characteristics of children with pediatric bipolar disorder (PBD), and these relationships may, in turn, be affected by the child's illness. We characterized maternal reports of parent-child relationships using the five-factor Parent-Child Relationship Questionnaire (PCRQ) in 60 families (30 PBD youth and 30 matched controls). Data on child proband and parental psychopathology were also obtained. Compared to controls, parent-child relationships in the PBD group were characterized by significantly less warmth, affection, and intimacy, and more quarreling and forceful punishment. Among PBD participants, elevated symptoms of mania, comorbid ADHD, an earlier age of illness onset, living in a single parent home, and the presence of a parental mood disorder were associated with greater parent-child relationship difficulties. These findings have implications for the development of interventions that focus on the quality of parent-child relationships, in addition to symptom management, in the treatment of PBD.

Analysis of candidate imprinted genes linked to Dlk1-Gtl2 using a congenic mouse line.

The study of genomic imprinting requires the use of DNA sequence polymorphisms between interfertile mouse species or strains. Most commonly, crosses between Mus musculus domesticus and Mus musculus castaneus or Mus spretus animals are used. Difficulties arise in the maintenance of these wild-derived mice in conventional animal facilities, however, and can be overcome by the use of a congenic strain for the region under study. We describe here the generation of a new mouse line, congenic for a region on distal Chromosome (Chr) 12 that encompasses the Dlk1-Gtl2 imprinted domain. We have taken a first step towards demonstrating the utility of these animals by assaying known genes located within the congenic interval for imprinted expression. We show that the two genes located immediately proximal to Dlk1, the Yy1 and Wars genes, are expressed in a biallelic manner. In addition, we have analyzed the Dio3 gene, located distal to Gtl2. This gene displays preferential expression of the paternal allele, with approximately 75% of the total message level originating from the paternal allele and 25% originating from the maternal allele. These data delineate the position of the Wars gene as the proximal boundary of the Dlk1-Gtl2 imprinted domain, and identify Dio3 as another potentially imprinted gene within this domain.
