Improvement of a slimming cream's efficacy using a novel fabric as a transdermal drug delivery system: An in vivo and in vitro study

A cross-sectional study on the use of big data for the past H1N1 influenza epidemic in obesity after COVID-19: Focused on the body slimming cream and leptin via DTC gene test

BACKGROUND

Based on the big data of 2010, 2011, and 2012, when H1N1 influenza was prevalent around the world in the past, this study investigated the obesity rate, weight change, and dietary methods of Korean dieters based on the historical situation of the past H1N1 influenza epidemic in Republic of Korea. This is intended to be the data for utilizing the prognostic evaluation of coronavirus disease-19 (COVID-19).

OBJECTIVE

After COVID-19, research on obesity should be conducted systematically, and to prevent obesity, nutrition education, customized inner beauty & cosmetics, and the development of body slimming cream and leptin for proper diet should be done at the national level. This study was conducted to investigate the relationship between methods of weight control, generation, and gender, which have not yet been evaluated in the Korean adult population.

METHODS

The cross-sectional study was comprised of 25 534 Korean who participated in the Fifth Korean National Health and Nutrition Examination Survey (KNHNES) conducted in 2010, 2011, and 2012.

RESULTS

A 17 876 of the 19 375 respondents 20 years of age or older in the KNHNES answered about diet method. Two thousand and fifty-seven (15.63%) men and 4134 (25.77%) women thought of themselves as fat. However, 11 973 people (66.96%) did not change weight in the past year, 2536 people (14.19%) had increase in weight, and 3.164 (17.70%) reduced weight. A total of 7176 people (48.11%) indicated that they attempted to reduce weight through exercising, while 5553 people (37.23%) did so through reduced food intake.

CONCLUSIONS

This study was based on big data at the time of the H1N1 influenza epidemic in Korean population. The results of the present study will be helpful in the development of the body slimming cream and leptin via direct to consumer (DTC) gene test (GT) due to the rapid increase in obesity due to COVID-19 pandemic.

Review of Applications and Future Prospects of Stimuli-Responsive Hydrogel Based on Thermo-Responsive Biopolymers in Drug Delivery Systems

Some of thermo-responsive polysaccharides, namely, cellulose, xyloglucan, and chitosan, and protein-like gelatin or elastin-like polypeptides can exhibit temperature dependent sol–gel transitions. Due to their biodegradability, biocompatibility, and non-toxicity, such biomaterials are becoming popular for drug delivery and tissue engineering applications. This paper aims to review the properties of sol–gel transition, mechanical strength, drug release (bioavailability of drugs), and cytotoxicity of stimuli-responsive hydrogel made of thermo-responsive biopolymers in drug delivery systems. One of the major applications of such thermos-responsive biopolymers is on textile-based transdermal therapy where the formulation, mechanical, and drug release properties and the cytotoxicity of thermo-responsive hydrogel in drug delivery systems of traditional Chinese medicine have been fully reviewed. Textile-based transdermal therapy, a non-invasive method to treat skin-related disease, can overcome the poor bioavailability of drugs from conventional non-invasive administration. This study also discusses the future prospects of stimuli-responsive hydrogels made of thermo-responsive biopolymers for non-invasive treatment of skin-related disease via textile-based transdermal therapy.
