METHODS AND STUDY DESIGN: The scoping review was performed using Arksey and O'Malley's methodological framework. The systematic search was conducted using Scopus, Pubmed, EBSCOHost and Google Scholar in April 2020, updated in March 2021. Only literature published between January 2010 until February 2021 was searched.

RESULTS: A total of 25 articles were included, of which 23 were randomised controlled trials , and 2 were quasi-experimental studies. Some of studies found improvements in depression (76% out of all studies). On this basis, nutrition or physical activity intervention probably improves postpartum depression. Moreover, the integration of nutrition and physical activity appears to improve depression in the more thorough follow-up of participants . Active involvement of the participant in the interventions was contributory to effectiveness.

METHODS: The information regarding the use of P. betle was retrieved from the books consisting of a Malay medical manuscript with an identification number MSS 2219 from the National Library of Malaysia. PubMed, ScienceDirect and Scopus databases were used to collect information regarding the scientific evidence for the medicinal use of P. betle. This review was written following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The keywords used for searching the articles included P. betle, antimicrobial, analgaesic, haepatic and gastric.

RESULTS: MSS 2219 showed that P. betle has varied medicinal uses and based on that, it can be grouped into six categories. P. betle application method was different in different conditions. In terms of the literature search, 226 articles were found, 75 articles were extracted for detailed analysis and only 23 met the inclusion criteria. The information was related to the chemical assays, in vivo and in vitro studies.

Materials and Methods: Ninety maxillary study models (30 from each group including males and females) were examined in the age group ranging from 18 to 25 years. The palatal rugae pattern was analyzed for shape.

Results: After analyzing the rugae patterns among the groups, the most common pattern was the wavy pattern (53.57%) followed by curved (18.22%) and straight (13.66%). The least was circular (1.3%). When compared between sex, the most common pattern was found to be wavy (male - 54.3% and female - 53.09%), while the curved pattern was more common among the females (21.09%) than males (13.97%). The straight pattern was more common among the males (18.8%) than females (10.18%). The least common pattern was found to be the circular in both sexes which accounted for around 1%.

METHODS: Forty male Sprague-Dawley rats (200-250 g) were used. Twenty-four animals were adrenalectomized and received intramuscular injection of dexamethasone (120 μg/kg/day). They were simultaneously administered with either Piper sarmentosum water extract (125 mg/kg/day), GCA (120 mg/kg/day) or distilled water as vehicle by oral gavage for two months. Eight animals were sham-operated and given vehicle daily, i.e. intramuscular olive oil and oral distilled water.

RESULTS: Following two months treatment, dexamethasone-treated adrenalectomized rats had significantly lower 11β-HSD1 dehydrogenase activity and higher 11β-HSD1 expression in the femoral bones compared to the sham-operated and baseline group. The rats supplemented with Piper sarmentosum water extract had significantly higher 11β-HSD1 dehydrogenase activity and lower 11β-HSD1 expression in the bones.
