1. Serial extraction of West Indian mahogany wood with selective solvents was performed. 2. The petroleum ether extract was the only fraction to exhibit promising termite-repellent activity. 3. Mahogany blocks subjected to petroleum ether extraction became susceptible to termite attack. 4. A waxy substance (P2 fraction) separated from the petroleum ether extract at times showed high termite-repellent activity. The termite-repellent principle in the P2 fraction seems to be a labile one, as the termite-repellent activity varied greatly from batch to batch. 5. The P2 fraction is a mixture of two major components and of at least a third minor one. As far as we have been able to determine this mixture, at the elemental level, contains carbon, hydrogen, and oxygen only, while esters have been the only compounds definitely characterized at the structural level.

Current research suggests COVID-19 in pregnancy is associated with poor maternal and fetal outcomes, although the exact mechanisms remain unclear, and the approach to the management of affected patients presents a distinct challenge to clinicians. We present a case of gestational hypertension, eclampsia, and postpartum depression in a 39-year-old gravida 4, para 0030 (G4P0) pregnant patient following multiple prenatal severe acute respiratory syndrome-related coronavirus 2 (SARS-CoV-2) infections. After a case of coronavirus disease-19 (COVID-19) during her first trimester, the patient received a two-dose mRNA vaccine against SARS-CoV-2. Despite vaccination, she again contracted COVID-19 during her third trimester of pregnancy. She subsequently developed gestational hypertension at 38 weeks necessitating a cesarean section at 38+4 weeks. The patient delivered a healthy neonate, however, her postpartum course was complicated by eclampsia and postpartum depression. This case bolsters current literature and emphasizes the necessity of continued research into the effects of COVID-19 in pregnant and postpartum women.
