Abstract

Highlights: 1. This study helps bridge the gap between systemic effects and tissue-level changes, providing a deeper understanding of how histological analysis can be used to explore the effects of intermittent fasting on adipocytes and body weight regulation. 2. This study contributes to obesity management through lifestyle modification, specifically intermittent fasting, by focusing on histological changes in adipose tissue. Abstract The accumulation of adipose tissue can have deleterious effects and lead to obesity. Intermittent fasting (IF), an approach that involves time-restricted eating, has gained popularity as an obesity treatment option because it enhances insulin sensitivity and promotes beneficial changes in glucose metabolism. This study used a time-restricted meal intake (TRM) approach to assess the effects of IF on the histological features of obese mouse models' subcutaneous inguinal adipose tissue. The investigation employed an in vivo experimental posttest-only control group design. Twenty male mice were divided into four groups: a normal control group, an obese control group, a TRM group with a high-fat diet (TRM-HF), and a TRM group with a standard diet (TRM-S). The TRM treatment was administered for fourteen days, with a fasting window from 4 p.m. to 8 a.m. The pre- and post-treatment weight analyses were conducted using the paired t-test for normally distributed data and the Wilcoxon test for non-normally distributed data (p<0.05). One-way analysis of variance (ANOVA) was employed for unpaired data on the post-treatment weight. Per field of view, there were an average of 120,500 cells (49,700–136,200) in the normal control group, 68,380±9,194 cells in the obese control group, 70,860±11,029 cells in the TRM-HF group, and 79,360±5,112 cells in the TRM-S group. The average cell sizes (μm3) were 56,730.142±19,273.257 in the normal control group, 138,934.331±27,670.558 in the obese control group, 106,827.767±20,580.501 in the TRM-HF group, and 68,689.114±8,219.727 in the TRM-S group. The number of cells in each group did not differ significantly, but there were significant variations in cell size. The mice receiving TRM treatment did not exhibit substantial body weight changes, whereas the obese control group showed a significant body weight increase. In conclusion, TRM has an effect on cell size but does not affect the quantity of adipocytes in subcutaneous inguinal fat tissue.

Abstract

Penuaan kulit merupakan proses biologis alami yang dapat dipercepat oleh paparan radiasi Ultraviolet B (UVB) hal tersebut memicu peningkatan ekspresi enzim Matrix Metalloproteinase-1 (MMP-1) sehingga merusak kolagen dan menurunkan elastisitas kulit. Penggunaan krim ekstrak tumbuhan sebagai alternatif pencegahan penuaan dini mulai mendapat perhatian karena kandungan senyawa antioksidan dan antiinflamasi yang berpotensi menurunkan ekspresi MMP-1. Penelitian ini bertujuan untuk mendeskripsikan pengaruh pemberian krim ekstrak tumbuhan terhadap ekspresi MMP-1 akibat paparan UVB berdasarkan tinjauan literatur sistematik. Metode yang digunakan adalah systematic review dengan mengikuti protokol PRISMA, melakukan pencarian artikel pada basis data Google Scholar, PubMed, dan ScienceDirect. Studi yang dianalisis meliputi penelitian in vitro dan in vivo pada model kulit hewan yang diinduksi UVB, dengan fokus pada efektivitas krim ekstrak tumbuhan dalam menurunkan ekspresi MMP-1. Hasil tinjauan menunjukkan bahwa krim ekstrak tumbuhan memiliki potensi menekan ekspresi MMP-1, namun efektivitasnya bervariasi tergantung jenis tumbuhan, senyawa fitokimia terkandung dan dosis yang dipakai. Temuan ini memberikan justifikasi empiris bagi pengembangan produk kosmetik berbasis ekstrak tumbuhan untuk pencegahan penuaan dini akibat paparan UVB

Abstract

The gonggongsea snail(Laevistrombussp.) is a typical marine life of the Riau Islands that contains various bioactive compounds with potential as wound healing agents based on natural ingredients. This study aims to evaluate the potential of gonggong seasnailextract through a literature review of articles obtained from PubMed, ScienceDirect, Google Scholar, and Scopus. Analysis of 18 articles showed that gonggongsea snailscontain histone protein H2A, antimicrobial peptides, flavonoids, alkaloids, saponins, as well as essential amino acids such as arginine, proline, and glycine that work synergistically throughout the wound healing phase. The compound plays a role in suppressing inflammation through inhibition of the NF-κB pathway and increasing IL-10, supporting the proliferation phase by stimulating angiogenesis and collagen synthesis, and improving the remodeling phase through improved tissue quality and antioxidant activity. Histological assessment can use the SPOT score system to show relevant parameters to evaluate the effectiveness of natural ingredients in wound healing. The results of this study confirm that gonggongsea snailextract has great potential to be developed as an effective, safe, and sustainable wound therapy candidate, so experimental research is needed to validate molecular mechanisms and standardize formulations.
