Abstract

Abstract:Indonesia is one of the tropical countries with year-round sunshine. This certainly allows Indonesians to be regularly exposed to the sun during daytime activities outside the home. Exposure to the sun has a significant impact on humans. To date, research on the prevalence of vitamin D deficiency, particularly in humans, has been rare. The purpose of  this literature review is to provide the reader with information on the effects of sun exposure on parathyroid hormone levels. The method used to write this document is the literary criticism method. (LRA) with references taken from published or revoked (POP) databases published between 2010 and 2022. In this literature review, the keywords used include including sun, hormones, activity, vitamin D, parathyroid glands. Based on literature from a variety of research findings, it was found that sun exposure affects parathyroid hormone levels. Because vitamin D in sunlight is in the  form of 1,25(OH)2D, it works with parathyroid hormone and calcitonin to maintain normal plasma calcium levels.

Abstract

Increasing tomato production requires special handling to increase longer shelf life by applying chitosan and modifying storage temperatures. Chitosan is a chitin derivative whose function is similar to wax compounds so that it is able to inhibit metabolic activity. Storage temperature of 10°C can extend shelf life and maintain the physical quality of tomatoes. This study aims to determine the effect of chitosan administration, the effect of storage temperature, and the effect of the combination of chitosan and storage temperature on the physical quality of tomatoes. This study used a Factorial Complete Randomized Design, the first factor was tomatoes without chitosan coating (K0), and tomatoes with chitosan coating (K1) = shrimp shell, (K2) = crab shell, (K3) = fish scales using the same concentration of 6%. The second factor is storage temperature (T1) = room temperature (26-32°C) and (T2) = temperature 10°C.  The changes observed are shrinkage in weight, color, texture, aroma, taste based on organoleptic test (hedonic test). Data analysis using ANOVA at 5% level and BNJ follow-up test at 5% level. The results showed that the use of crab chitosan (K2) had an effect on weight loss (0.42%). Storage temperature of 10°C (T2) affects weight loss (5.04%). The best treatment combination for weight loss (0.07%) and color (7.40) was crab chitosan and temperature of 10°C (K2T2), while the best treatment combination for texture (7.56), aroma (7.08), and taste (7.16) was fish scales and temperature of 10°C (K3T2). In general, the best treatment is chitosan fish scales and a temperature of 10°C (K3T2).

Abstract

Tapak dara (Catharanthus roseus) leaf contain phytoestrogen compounds such as flavonoids, isoflavonoids, saponins, and tannins, and contain alkaloid compounds. Phytoestrogens are compounds contained in plants, having a chemical structure resembling 17β-Estradiol in the body's natural estrogen. This study aims to determine the effect of tapak dara leaf extract on the growth of ovarian follicles of mice (Mus musculus), consisting of primary follicles, secondary, tertiary, and de Graaf follicles. This research method is true experiment and Posstest-Only Control with a quantitative approach. Sampling was carried out randomized block design (RBD). The growth of mice ovarian follicles is known by counting the number of mice ovarian follicles, analyzed using the ANOVA one-way test analysis method at a sig. level of 5% (α = 0.05), then if there is a difference, proceed with a further test of Least Significant Difference) at a sig. level of 5% (α = 0.05). Data analysis using Microsoft Excel 2010. The results of the hypothesis test using One Way ANOVA stated that Fcalculate > Ftable at sum of primary follicles, which means that there is a real difference and Ha is accepted. The results of hypothesis tests at sum of secondary, tertiary, and de Graaf follicles stated that Fcalculate < Ftable, which means there is no real difference and Ha is rejected. The conclusion of this study is that tapak dara leaf extract has a significant effect on the growth of primary follicles, but does not significantly affect the growth of secondary, tertiary, and de Graaf follicles.

Abstract

Anemia is the most common conditions detected by primary care doctors in Indonesia and worldwide. In 2010, the global prevalence of anemia was 32.9%; that is, more than 2.2 billion people have anemia in the world. Macrocytic anemia refers to a condition that refers to macrocytosis, or when the mean corpuscular volume (MCV) is greater than 100 fL in moderate anemia, the hemoglobin is less than 12 g/dL, or the hematocrit is less than 36%. To identify the etiology and course of the disease in macrocytic anemia. This writing uses the method of studying the relevant literature related to the etiology and course of the disease, macrocytic anemia. The search engines used in this paper include Pubmed, Google Scholar, Research Gate, NCBI, and BMC. This article uses 22 articles that were used as references in its preparation. Megaloblastic anemia has etiologies in the form of vitamin B12 and folate deficiency, while non-megaloblastic anemia has etiologies such as alcohol consumption, MDS, hyperthyroidism, etc. The disease course of the two types of macrocytic anemia also differs based on the type, namely megaloblastic and non-megaloblastic. In general, macrocytic anemia is divided into megaloblastic anemia and non-megaloblastic anemia; these divisions have different etiologies dan pathogenesis.
