Background:
and Purpose Repetitive transcranial magnetic stimulation (rTMS) of the cerebellar hemisphere represents a new option in treating essential tremor (ET) patients. We aimed to determine the efficacy of cerebellar rTMS in treating ET using different protocols regarding the number of sessions, exposure duration, and follow-up duration.
Methods:
A randomized sham-controlled trial was conducted, in which 45 recruit patients were randomly allocated to 2 groups. The first (active group) comprised 23 patients who were exposed to 12 sessions of active rTMS with 900 pulses of 1-Hz rTMS at 90% of the resting motor threshold daily on each side of the cerebellar hemispheres over 4 weeks. The second group (sham group) comprised 22 patients who were exposed to 12 sessions of sham rTMS. Both groups were reassessed at baseline and after 1 day, 1 month, 2 months, and 3 months using the Fahn-Tolosa-Marin tremor-rating scale (FTM).
Results:
Demographic characteristics did no differ between the two groups. There were significant reductions both in FTM subscores A and B and in the FTM total score in the active-rTMS group during the period of assessment and after 3 months (p=0.031 and 0.011, respectively).However, subscore C did not change significantly from baseline when assessed at 2 and 3 months (p=0.073 and 0.236, respectively). Furthermore, the global assessment score was significantly higher in the active-rTMS group (p>0.001).
Conclusions
Low-frequency rTMS over the cerebellar cortex for 1 month showed relative safety and long-lasting efficacy in patients with ET. Further large-sample clinical trials are needed that include different sites of stimulation and longer follow-ups.

One of the leading causes of death worldwide is cardiovascular disease, hence searching for a cure is an important endeavor. The totally safe, edible, and inexpensive Boswellia plant exudate, known as olibanum or frankincense, is considered to possess diverse medicinal values in traditional medicine and from recent biological studies. Investigating the cardioprotective and antioxidant activities of olibanum from a Boswellia species, family Bursearaceae, namely Boswellia carteri Birdw. was the aim of this study. Cardioprotective activity was evaluated using a model of myocardial infarction induced by isoprenaline (ISO), while antioxidant activity was tested adopting nitric oxide scavenging (NOS) and azino-bis-3-ethyl benzthiazoline-6-sulfonic acid (ABTS) assays. The results revealed a mild cardioprotective effect and weak antioxidant activity.
