Učinkovitost kalijeva permanganata i kurkume kao antimikrobnih tvari na broj bakterija i kvalitetu nerastovog sjemena pohranjenog na 15 °C

The present study was conducted to evaluate the efficacy of different natural antimicrobials agents (KMnO4 and Turmeric) in comparison with conventional antibiotics against the bacterial load and in relation to the quality of boar semen in Modena extender for up to 120 hours of preservation at 15 °C. A total of 56 ejaculates, 14 from each of four Hampshire crossbred boars maintained within the ICAR-AICRP on Pigs, in Guwahati, Assam, India, were utilized in the study. Thirty-two ejaculates, 8 from each of four boars were used to study the effect of antimicrobial agents on semen quality during preservation at 15 °C in Modena extender. A total of 9 different bacterial types were identified from 46 bacterial isolates, obtained from 24 fresh semen samples viz. Staphylococcus aureus (24%), E. coli (22%), Bacillus spp. (13%), Citrobacter spp. (9%), Pseudomonas spp. (9%), Staphylococcus epidermidis (9%), Klebsiella spp. (6%), Streptococcus spp. (6%) and Proteus spp. (2%). The overall sensitivity of the recovered isolates to Gentamicin, Ampicillin, Enrofloxacin, Cloxacillin, Streptomycin, Penicillin, Amoxycilln, Ofloxacin and Tetracyclin were 89, 39, 37, 48, 74, 52, 56, 76 and 63% respectively. The mean sperm motility, intact acrosome, HOST-reacted spermatozoa and bacterial load differed significantly (P˂0.01) between antimicrobial agents (Gentamicin, KMnO4 and Turmeric) and preservation periods (0, 48, 72, 96 and 120 hours). Sperm quality based on Gentamicin was found to be best, followed by Turmeric and KMnO4 during preservation at 15 °C. The conception rate for the semen preserved for 0, 24, 48, 72, 96 and 120 hours of preservation was 83.33, 80.00, 75.00, 66.66, 66.66 and 50.00% respectively. In the present study, the preserved semen with ascending bacterial load containing Gentamicin did not affect the conception rate.Istraživanje je provedeno kako bi se procijenila učinkovitost različitih prirodnih antimikrobnih tvari (KMnO4 i kurkume) u odnosu na konvencionalne antibiotike na broj bakterija i kvalitetu nerastova sjemena, pohranjenog u ekstenderu Modena do 120 sati na 15 °C. Upotrijebljeno je ukupno 56 ejakulata, 14 od svakoga od četiri nerasta križane pasmine Hampshire, uzgajanih u centru za istraživanje svinja ICAR-AICRP, Guwahati, Assam, Indija. Trideset i dva ejakulata, po 8 od svakoga od 4 nerasta, upotrijebljena su kako bi se istražili učinci antimikrobnih tvari na kvalitetu sjemena za vrijeme njegove pohrane u ekstenderu Modena na 15 °C. Identificirano je ukupno 9 različitih bakterijskih tipova iz 46 bakterijskih izolata dobivenih od 24 uzorka svježeg sjemena, i to Staphylococcus aureus (24 %), E. coli (22 %), Bacillus spp. (13 %), Citrobacter spp. (9 %), Pseudomonas spp. (9 %), Staphylococcus epidermidis (9 %), Klebsiella spp. (6 %), Streptococcus spp. (6 %) i Proteus spp. (2 %). Ukupna osjetljivost dobivenih izolata bila je: 89 % na gentamicin, 39 % na ampicilin, 37 % na enrofloksacin, 48 % na kloksacilin, 74 % na streptomicin, 52 % na penicilin, 56 % na amoksicilin, 76 % na ofloksacin i 63 % tetraciklin. Prosječna pokretljivost spermija, intaktni akrosomi, reaktivnost sjemena na hipoosmotski test bubrenja (HOST) i broj bakterija znakovito su se razlikovali (P ˂ 0,01) među antimikrobnim tvarima (gentamicin, KMnO4 i kurkuma) i s obzirom na trajanje pohrane (0, 48, 72, 96 i 120 sata). Tijekom pohrane na 15 °C, najbolja je bila kvaliteta sperme tretirane gentamicinom a zatim ona tretirana kurkukom i KMnO4. Postotak koncepcije bio je 83,33 % za sjeme koje nije bilo pohranjeno, 80,00 % za sjeme pohranjeno 24 sata, 75,00 % za sjeme pohranjeno 48 sati, 66,66 % za sjeme pohranjeno 72 sata, 66,66 % za sjeme pohranjeno 96 sati i 50,00 % za sjeme pohranjeno 120 sati. U ovom istraživanju porast broja bakterija u pohranjenom sjemenu tretiranom gentamicinom nije utjecao na postotak koncepcije

Collection Analysis of Print Resources in Tezpur University: A Study

The purpose of this study is to investigate school and year wise growth and amount utilized for print books and periodicals collections in Central Library, Tezpur University during the period 2013-2017. Data about new addition, year wise expenditure of books and periodicals for the period under study were collected from the annual reports, NAAC reports and from the available records maintained in the library. Finally depending upon the findings authors suggested that there is urgent need to allocate more funds to the university library to acquire more number of books and periodicals to satisfy user’s information need with changing information environment

A polyaniline-containing filter paper that acts as a sensor, acid, base, and endpoint indicator and also filters acids and bases

In this paper we report a new idea for synthesizing polyaniline in an ordinary filter paper. The synthesis was carried out by a process in which aqueous acidic aniline solution and the oxidizing agent H2O2 was added to the paper drop by drop and in sequence. Uniform polymerization could be obtained with the addition of reagents in either sequence. The polymer formation led to a green coloration of the paper. Formation of the emeraldine salt of polyaniline was confirmed by UV–vis and FTIR spectroscopy. Scanning electron microscopic measurements were made for surface characterization of the polymer formed in the paper. The same paper was used as a sensor for ammonia in vapor and in solution, for acid and base as well as endpoint indication, and also to filter acids and bases. We found that, using the polymer-containing paper, ammonia concentrations in a solution as low as 14 ppm could be measured

Microwave-Promoted Catalyst- and Solvent-Free Aza-Diels–Alder Reaction of Aldimines with 6-[2-(Dimethylamino)vinyl]-1,3-dimethyluracil

A microwave-promoted aza-Diels–Alder reaction between 6-[2-(dimethylamino)­vinyl]-1,3-dimethyluracil and aldimines has been developed for the construction of dihydropyrido­[4,3-<i>d</i>]­pyrimidines. Urea is effectively employed as an environmentally benign source of ammonia in the absence of any catalyst or solvent. The key step in the reaction is in situ generation and trapping of the reactive aldimine formed from urea and aldehyde by the diene system of the uracil. The reaction is clean, and excellent yields are obtained in a matter of a few minutes

BICARBONATE DOSING AT DIFFERENT BLOOD PH LEVELS IN METABOLIC ACIDOSIS, ITS RELEVANCE AND OUTCOME- A SINGLE-CENTERED PROSPECTIVE STUDY.: sodium bicarbonate, metabolic acidosis, pH

Background: Acute acidemia is a frequently observed condition in intensive care units. Intravenous sodium bicarbonate is one possible modality of treatment along with IV fluid and treating the primary cause. Most authors advocate bicarbonate therapy at an arterial pH of ≤ 7.1 but some advocate as early as when blood pH level starts falling below 7.2. This cut-off level remains a controversy. This study aimed to administer sodium bicarbonate in metabolic acidosis at different blood Ph levels and observe its effects on patients’ ABG and outcomes. Methods: The target was to maintain arterial pH of 7·20 and above. The comparison was made based on biochemical and clinical outcomes in two different groups where the group I with a blood pH. of &lt; 7.2 and group II with a blood pH of &lt; 7.1. Results: In the present study on day 2 pH increased from 7·16 ± 0.0453 to 7.27 ± 0.056 in group I and from 6.82 ± 0.0944 to 6.85 ± 0.0448 in group II.  Hco3 increased from 8.9 ± 2.82 to 14.8 ± 3.46 in group I and from 3.9 ± 3.48 to 4.9 ± 3.8 in group II. Group I showed better correction of acidosis and bicarbonate level on day 2. Higher bolus dosages are required in group II and still insignificant rise in bicarbonate or change in pH. Conclusion: Preemptive sodium bicarbonate administration at a blood pH of 7.2 and bicarbonate level &lt;15 rather than waiting for pH to fall below 7.1 has shown better primary outcomes in patients with severe metabolic acidemia. Its effects on mortality have not been evaluated. Whether sodium bicarbonate infusion could influence the outcome must be evaluated more in future trials. Additional investigations evaluating therapeutic interventions could be of significance within the cohort of individuals experiencing metabolic acidosis in the ICU
