Background: Vitamin B12 deficiency has been associated with peripheral neuropathy, loss of sensation in the peripheral nerves, and weakness in the lower extremities. Methylcobalamin is the most effective analogue of vitamin B12 used to treat or prevent the complications associated with vitamin B12 deficiency. The current study aimed to compare the serum cobalamin levels after administration of two different regimes of methylcobalamin in peripheral neuropathy patients. Methods: The present study was a prospective, randomized, comparative study. The study consisted of two parallel groups, group A (methylcobalamin 500 μg injection intramuscularly three times a week) and group B (methylcobalamin 1500 μg injection intramuscularly once a week). A control group of healthy volunteers was also included. Results: A total of 24 patients (12 in each group) were included in the study. Five healthy volunteers were also included as a control in each group. At the end of treatment, serum cobalamin levels were significantly (P = 0.028) higher in group A (1892.08 ± 234.50) as compared with group B (1438.5 ± 460.32). The serum cobalamin levels in Group A healthy volunteers were also two times higher than that of group B (P = 0.056). Both the LANSS scale and DN4 questionnaire reported similar results at end of treatment. Conclusions: The 500 μg methylcobalamin thrice weekly regime is more effective in increasing the serum cobalamin levels as compared to the 1500 μg methylcobalamin once weekly regime.

A novel design for the planar monopole antenna presented in this article consists of a patch resembling a tree and a modified ground plane resembling a flower vase. The proposed antenna is planned, designed, and made by utilizing FR4 substrate. The proposed antenna contributes to a computer simulation and tested S11 bandwidth of 9.4 GHz (144.62%) and 9.3 GHz (136.76%), respectively. A peak tested gain of 6.5 dBi and peak efficiency of 77.51% have been achieved. The measured results of the fabricated antenna are compared with the simulated results and are found to be in good agreement. The proposed antenna has a low general volume of 38 × 20 × 1.6 mm<sup>3</sup> . The antenna can be used in C-band and X-band application.
