In this paper, we study the approximation of unbounded functions in a weighted space by modulus smoothness using various linear operators. We establish direct theorems for such approximations and analyze properties within same space. Specifically, investigate behavior under different types operators, including Bernstein-Durrmeyer operator, Fejer Jackson operator. also provide detailed analysis ...

hirudin is an anticoagulant agent of the salivary glands of the medicinal leech. recombinant hirudin (r-hir) displays certain drawbacks including bleeding and immunogenicity. to solve these problems, cysteine-specific pegylation has been proposed as a successful technique. however, proper selection of the appropriate cysteine residue for substitution is a critical step. this study has, for the ...

micropapillary variant of urothelial carcinoma (uc) of the bladder is an aggressive tumour, comprising 0.6-6% of all uc. it generally presents with high-grade and stage, and has been reported as having a worse prognosis when compared to traditional uc. we report the case of a 58-year-old man who presented with macroscopic haematuria. the patient was diagnosed with high-grade urothelial carcinom...

staphylococcus aureus produces a particular morphological variant called small colony variant (scv) which is responsible for persistent subclinical infections in predisposed individuals and is usually resistant to aminoglycosides and cell wall active antibiotics. infections by scv of s. aureus are an upcoming problem due to difficulty in laboratory diagnosis and resistance to antimicrobial chem...

acute myocardial infarction (mi) during pregnancy is rare and mi due to prinzmetal's angina is much rarer. we present a 35-year-old, obese, multigravida, and pre-eclamptic woman, who developed acute anterior wall mi at the 30th week of gestation. on coronary angiography, the second obtuse marginal branch was totally occluded and the right coronary artery (rca) was normal. three days later, she ...
