Article Synopsis
- Tuberculosis lymphadenitis is a common form of extra-pulmonary TB, traditionally requiring six months of treatment, but this study explored a potential four-month regimen using ofloxacin.
- The trial involved adult TB patients randomly assigned to either a four-month ofloxacin-based treatment or a traditional six-month regimen, with outcomes assessed based on TB recurrence and treatment success.
- Results showed the four-month regimen was as effective and safe as the six-month control, with similar rates of favorable response and manageable side effects, making it a promising alternative.
A new type of 4-isopropylcalix[4]arene-capped (3-(2-O-β-cyclodextrin)-2-hydroxypropoxy)propylsilyl-appended silica particles (IPC4CD-HPS) has been prepared by treatment of bromoacetate-substituted (3-(2-O-β-cyclodextrin)-2-hydroxypropoxy)propylsilyl-appended silica particles (BACD-HPS) with 4-isopropylcalix[4]arene oxyanions in anhydrous N-methyl-2-pyrrolidone. The bonded silica IPC4CD-HPS has been successfully used as chiral stationary phase (CSP) in high-performance liquid chromatography (HPLC) for the first time. The synthetic stationary phase was characterized by means of elemental analysis and Fourier transform infrared spectroscopy.

The stationary phase is characterized by means of elemental analysis and Fourier-transform infrared spectroscopy. This new CSP has a chiral selector with two recognition sites: rifamycin and β-cyclodextrin (β-CD).
