Characteristics of surface modified sugarcane bagasse cellulose: application of esterification and oxidation reactions.

Research on polymer matrix composites has become increasingly important in both the academic and industrial sectors. The study of polymer-natural fiber composites, known for their eco-friendly properties, has gained significance. Sugarcane bagasse fibers, abundant as discarded agricultural byproducts, offer improved properties such as density, rigidity, strength, and cost-effectiveness, enhancing sustainability.

Correlation of retinal nerve fiber layer thickness with perimetric staging in primary open-angle glaucoma - A cross-sectional study.

Background: Glaucoma is a progressive optic neuropathy, characterized by structural optic nerve damage with corresponding field defects. Primary open-angle glaucoma (POAG) is the most common. Although perimetry is the gold standard, retinal nerve fiber layer (RNFL) thickness by spectral-domain optical coherence tomography (SD-OCT) has proved reliable in the detection of pre-perimetric glaucoma.

Subconjunctival dirofilariasis: Case studies with review of literature.

Human dirofilariasis is an uncommon zoonotic parasitic infection caused by species of the genus Dirofilaria. Location of the worm is usually confined to the subcutaneous tissues of eyelids, fingers, cheeks and breasts. Ophthalmic involvement is usually periorbital, intraocular or of the eyelids.

Synthesis and antimosquito properties of 2,6-substituted benzo[d]thiazole and 2,4-substituted benzo[d]thiazole analogues against Anopheles arabiensis.

A novel and efficient one pot synthesis was developed for 2,6-substituted-benzo[d]thiazole analogues 4a-k and 2,4-substituted-benzo[d]thiazole analogues 4l-pvia three component condensation reaction of substituted arylaldehyde, 2-amino-6-halo/4-methyl-benzo[d]thiazole and 2-naphthol or 6-hydroxyquinoline in presence of 10% w/v NaCl in water by microwave method. This method enabled for short reaction times, easy work-up and significant high yields. The title compound 4b was used for single crystal X-ray studies in order to understand its conformation and packing features.

Synthesis and antitumor activity studies of some new fused 1,2,4-triazole derivatives carrying 2,4-dichloro-5-fluorophenyl moiety.

A series of 3-(2,4-dichloro-5-fluorophenyl)-6-(substituted phenyl)-1,2,4-triazolo[3,4-b]-1,3,4-thiadiazines (4) (Fig. 1) have been synthesized by the cyclization of 3-(2,4-dichloro-5-fluorophenyl)-1,2,4-triazol-5-thiol (3) with substituted phenacyl bromides. All the newly synthesized compounds were confirmed by IR, (1)H NMR and mass spectral studies.
