Comparative study between Conventional Adenoid Curettage and Endoscopic Assisted Adenoid Curettage

Adenoidectomy is a common procedure done for various causes like chronic adenoiditis or chronic adenotonsillitis or adenoid hypertrophy with middle ear and sinus disorders. Clinical features includes rhinorrhea, chronic mouth breathing, excessive snoring, apneic episodes, enuresis, daytime somnolence, neurocognitive and learning problems. Adenoidectomy provides a symptomatic recovery with improvement in the quality of life and health status of the patients. In this study we discussed on COMPARATIVE STUDY BETWEEN CONVENTIONAL ADENOID CURETTAGE AND ENDOSCOPIC ASSISTED ADENOID CURETTAGE. The results we obtained suggested that the endoscopic assisted adenoid curettage is comparatively better in the post operative tissue remnant, Eustachian tube injury, symptomatic relief

Ascaroside Expression in Caenorhabditis elegans Is Strongly Dependent on Diet and Developmental Stage

Background: The ascarosides form a family of small molecules that have been isolated from cultures of the nematode Caenorhabditis elegans. They are often referred to as “dauer pheromones” because most of them induce formation of long-lived and highly stress resistant dauer larvae. More recent studies have shown that ascarosides serve additional functions as social signals and mating pheromones. Thus, ascarosides have multiple functions. Until now, it has been generally assumed that ascarosides are constitutively expressed during nematode development. Methodology/Principal Findings: Cultures of C. elegans were developmentally synchronized on controlled diets. Ascarosides released into the media, as well as stored internally, were quantified by LC/MS. We found that ascaroside biosynthesis and release were strongly dependent on developmental stage and diet. The male attracting pheromone was verified to be a blend of at least four ascarosides, and peak production of the two most potent mating pheromone components, ascr#3 and asc#8 immediately preceded or coincided with the temporal window for mating. The concentration of ascr#2 increased under starvation conditions and peaked during dauer formation, strongly supporting ascr#2 as the main population density signal (dauer pheromone). After dauer formation, ascaroside production largely ceased and dauer larvae did not release any ascarosides. These findings show that both total ascaroside production and the relative proportions of individual ascarosides strongly correlate with these compounds' stage-specific biological functions. Conclusions/Significance: Ascaroside expression changes with development and environmental conditions. This is consistent with multiple functions of these signaling molecules. Knowledge of such differential regulation will make it possible to associate ascaroside production to gene expression profiles (transcript, protein or enzyme activity) and help to determine genetic pathways that control ascaroside biosynthesis. In conjunction with findings from previous studies, our results show that the pheromone system of C. elegans mimics that of insects in many ways, suggesting that pheromone signaling in C. elegans may exhibit functional homology also at the sensory level. In addition, our results provide a strong foundation for future behavioral modeling studies

Chlamydomonas DYX1C1/PF23 is essential for axonemal assembly and proper morphology of inner dynein arms

Cytoplasmic assembly of ciliary dyneins, a process known as preassembly, requires numerous non-dynein proteins, but the identities and functions of these proteins are not fully elucidated. Here, we show that the classical Chlamydomonas motility mutant pf23 is defective in the Chlamydomonas homolog of DYX1C1. The pf23 mutant has a 494 bp deletion in the DYX1C1 gene and expresses a shorter DYX1C1 protein in the cytoplasm. Structural analyses, using cryo-ET, reveal that pf23 axonemes lack most of the inner dynein arms. Spectral counting confirms that DYX1C1 is essential for the assembly of the majority of ciliary inner dynein arms (IDA) as well as a fraction of the outer dynein arms (ODA). A C-terminal truncation of DYX1C1 shows a reduction in a subset of these ciliary IDAs. Sucrose gradients of cytoplasmic extracts show that preassembled ciliary dyneins are reduced compared to wild-type, which suggests an important role in dynein complex stability. The role of PF23/DYX1C1 remains unknown, but we suggest that DYX1C1 could provide a scaffold for macromolecular assembly

Short-route synthesis of (3E,5Z)-tetradecadienoic acid (megatomic acid), the sex attractant of the black carpet beetle

A new and expeditious route to (3E,5Z)-3,5-tetradecadienoic acid (megatomic acid), the sex attractant of the black carpet beetle Attagenus megatoma (Fabricius), is reported which proceeds with 97% stereoselectivity; Cadiot-Chodkiewicz cross-coupling of 1-decyne and 4-bromo-3-butyn-1-ol in the presence of CuCl, followed by stereoselective reductions and Jones oxidation, gives the target molecule, with the synthetic pheromone showing a positive electrophysiological response

Fractional difference inequalities of Gronwall-Bellman type

Discrete inequalities, in particular the discrete analogues of the Gronwall–Bellman inequality, have been extensively used in the analysis of nite difference equations. The aim of the present paper is to establish some fractional difference inequalities of Gronwall–Bellman type which provide explicit bounds for the solutions of fractional difference equations

AN EVALUATION ON PRESCRIBING PATTERN OF ANTIBIOTICS IN PAEDIATRIC INPATIENTS AT TERTIARY CARE HOSPITAL

Objective: Our objective of the study was to evaluate the prescribing patterns of drugs with cost analysis in pediatric inpatients at tertiary care hospital. Methods: It is an observational prospective study carried out in pediatric inpatients with a sample of 180 patients based on age, inclusion, and exclusion criteria for period of 3 months. The patient’s data were collected using patient case record form and analysis of the data was done. Results: Of 180 patients data were collected, the results show that majority of gender admitted in the hospital were male children 94 (52%) and many are from age group of early childhood (2–5 years) 67 (37%). Respiratory tract infections are diagnosis most commonly analyzed and off overall 236 prescribed antibiotics cephalosporins 86 (43%) and combination of amoxicillin + clavulanic acid 25 (71%) is the class of antibiotics prescribed higher than other class of drugs. Parental 173 (73%) route of administration was observed to be followed more than other route. The percentage of cost variation of antibiotics observed in the study reveals that the huge variations were seen in the cost of medication in maximum and minimum cost. Conclusion: The present study reveals that the prescribed antibiotics were as per the diagnosis of the patient and not by proceeding proper culture sensitivity testing. Hence, awareness about antibiotic must be created among practicing physicians to increase the therapeutic compliance of the patient
