Generalization of Renyi’s Entropy and its Application in Source Coding

In this paper, we introduce a new generalization of Renyis entropy β(P) and the most important feature of this generalized entropy Rαβ (P) is that it derives most important entropies that are well known and influence information theory and applied mathematics. Some significant properties of Rαβ (P) has been undertaken in this article. In addition, we introduce a new generalized exponentiated mean codeword length Lβα (P) in this article then determine how Rβα (P) and Lβα (P) are related in terms of source coding theorem

Role of biomarkers in predicting anastomotic leakage following colorectal surgeries

Background: Recovery after surgery for patients with colorectal disease has improved with the advent of minimal access surgery and standardized recovery protocols. Despite these advances, anastomotic leakage remains one of the most dreaded complications following colorectal surgery, with rates of 3-27 per cent depending on specific risk factors. The aim of the study was to assess sensitivity and specificity of systemic and peritoneal drain-fluid bio-markers in early prediction of anastomotic leak; and to co-relate rise in levels of biomarkers and severity of clinical symptoms in patients who have undergone colo-rectal surgeries.Methods: The present study was a prospective observational study conducted on 60 patients in the Postgraduate Department of Surgery, Government Medical College, Srinagar after obtaining due ethical clearance over a period of two years.Results: The mean age was 54.87±11.901 years with 44 patients (73.3%) were males. Among systemic makers: the mean CRP level was 2.7800±0.500 mg/L, the mean total leukocyte count was 10.783±0.940 thousands and the mean serum procalcitonin level was 0.365±0.1385 ng/ml. Among peritoneal fluid drain bio-makers, the mean IL-6 level was 3551.066±1311.965 pg/ml, the mean IL-10 level was 628.533±460.358 pg/ml and the mean TNF-a level was 16.391±6.736 pg/ml. The anastomotic leak after colo-rectal surgery was noted in 16 patients (26.7%). In our study significant co-relation was noted between the rise in levels of peritoneal drain fluid biomarkers and severity of clinical symptoms but no significant co-relation was noted between the rise in levels of systemic markers and severity of clinical symptoms in patients who have undergone colo-rectal surgeries.Conclusions: Systemic biomarkers are poor predictors of anastomotic leak after colorectal surgery. But sensitivity and specificity of peritoneal fluid drain biomarkers in predicting anastomotic leak was significantly high

Tf₂O‑Promoted Regioselective Heteronucleophilic Ring-Opening Approaches of Tetrahydrofuran

The ring-opening functionalization strategy in tetrahydrofuran (THF) represents an ideal approach to access different valuable structures. Herein, we report different operationally simple, efficient, unique, and practical regioselective heteronucleophilic ring-opening strategies for the THF system. Tf2O, which is a strong electrophilic activator, was found to generate a THF triflate intermediate that triggers the nucleophilicity of nitriles (Nu1) and led to regioselective ring opening in the presence of different nucleophiles (Nu2). Furthermore, the synthesis of different heteronucleophilic ring-opening dimerization products was attributed to the nucleophilicity of Nu2. We also demonstrated that use of borane–tetrahydrofuran (BTHF) can achieve challenging hydride addition in a similar manner

Antibacterial Activity of Some Medicinal Plants of Kashmir, J&K, India

The study was conducted to find out the activity of some medicinal plants against bacterial isolates. The bacterial isolates from milk samples of infected quarters of cows were investigated for in-vitro drug sensitivity by standard disc diffusion technique (Bauer et al., 1966). Cultural examination of milk samples was done by method described by Quin et al. (2004) in which predominant isolates were Staph. (55.55%), E. coli (22.22%), Strepto. agalactiae (16.66%) and other isolates as 5.5% and were subjected to in-vitro antibacterial sensitivity test to selected herbal extracts and standard antibiotic (cefuroxime) (Table-1). The four different aqueous concentrations of the herbs namely Fumaria indica, Adiantum capillus, Nepata cataria, Levandula stoeches and Borago officinalis collected from registered herbal shops prepared by standard procedure as 25mg/ml, 50mg/ml, 75mg/ml and 100mg/ml were used. The results indicated that aqueous extract of Fumaria indica, Adiantum capillus and Napeta cataria against Staphylococcus aureus, E.coli, Streptococcus agalactia and K. pneumonia exhibited maximum zone of inhibition 20.0±1.21, 21.0±0.19, 13.0±0.37 17.0±0.21; 18±0.41, 12±0.21, 13±0.31, 15±0.31 and 15±0.33, 16.01±0.19 14.09±0.37, 13.31±0.41 at 100 mg/ml respectively which was significantly low as compared to standard drug (cefuroxime) at 30 microgram concentration. Aqueous extract of Levandula stoeches against Staphylococcus aureus and E.coli exhibited maximum zone of inhibition 18.0±0.33 and 13.0±0.141 at 100 mg/ml respectively. Borago officinalis has shown nil to non-significant bacterial growth inhibition activity
