Abstract

Semen quality is one of the most important factors for the success of artificial insemination. The quality of the diluent really determines the quality of the liquid semen. Therefore, research to find the most optimal diluent to maintain the quality of liquid semen, whether stored at room temperature, cold or frozen, is continuously being carried out. The aim of this research was to determine the motility and viability of Boer cross goat spermatozoa in Tris albumin extender supplemented with fig fruit filtrate and stored at cold temperatures. This study used a completely randomized design (CRD) with 4 treatments, namely P0 (standard Tris extender + 2.5% egg yolk), Pl (Tris standard extender + 2.5% albumin), P2 (P1 + 4% fig fruit filtrate), and P3 (P1+6% fig fruit filtrate). Evaluation of fresh semen includes volume, color, aroma, consistency, degree of acidity (pH), mass motility, individual motility and spermatozoa viability. The variables observed in this study were individual motility and spermatozoa viability up to a minimum motility limit of 40%. The results showed that the addition of fig filtrate to the Tris-albumin based extender did not increase the ability of the extender to maintain spermatozoa motility and viability compared to the standard Tris-egg yolk extender. In conclusion, the addition of fig fruit filtrate to the Tris egg albumin extender had no better effect than the standard Tris-egg yolk extender. To get better results, further studies are needed on various concentration combinations between albumin and fig fruit filtrate in Tris-albumin based.

Abstract

Post-partum depression (PPD) is a depressive episode that lasts up to four weeks after childbirth. Depression in mothers can affect various aspects of life, such as work, family, spouse, and children. There is a high incidence of suicidal thoughts in mothers who experience PPD, contributing significantly to maternal mortality rate. Understanding more about DPP is the main focus of this paper. This article utilizes a literature review method that collects sources from PubMed, Google Scholar, and Science Direct. This literature review explores various aspects of PPD including epidemiology, pathophysiology, clinical manifestations, diagnosis and treatment. Various physiological changes in the mother's body before and after childbirth increases the mother's vulnerabilities to mood disorders. The mechanisms of PPD involve various pathways, both external and internal. Internal factors include a decrease in certain hormones and neurotransmitters, a history of mental health disorders, and genetic predispositions. External factors include anxiety, external pressures, and lack of social support. The diagnosis of PPD can be established using the DSM-V and ICD-10 criteria. Treatment for PPD can involve both non-pharmacological and pharmacological therapies. PPD is a serious mental condition that causes various negative effects for both the mother and her family. The dysregulation of neuro-hormonal pathways is the primary mechanism in the pathogenesis of PPD. Effective diagnosis and appropriate treatment approaches are crucial in the management of PPD.

Abstract

Reye's syndrome is a rare disease that has the potential to damage several organs, particularly the brain and liver. The exact cause remains unknown, but several cases suggest a link to viral and bacterial infections, especially Influenza and Varicella. The clinical symptoms of Reye's syndrome include altered consciousness, fever, seizures, lethargy, vomiting, tachycardia, respiratory rhythm disturbances, changes in muscle tone, altered reflexes, and reduced urine production. This study aims to understand the clinical characteristics and evaluate the effectiveness of management in patients with Reye's syndrome through a literature review. The findings indicate that Reye's syndrome frequently affects children following viral infections, with initial symptoms of vomiting and altered consciousness progressing to coma. Laboratory tests reveal elevated liver enzymes and hypoglycemia, while prompt management, such as stabilizing vital functions and managing intracranial pressure, can improve prognosis. In conclusion, Reye's syndrome requires rapid intervention to prevent further organ damage, and education on the risks of aspirin use in children with viral infections, along with early intervention, is crucial to reducing morbidity and mortality associated with this condition.

Abstract

Hepatic cirrhosis is a chronic liver disease characterized by fibrosis and regeneration of nodules in the liver, which if it occurs for a long time, hepatocyte cells will be damaged so that they cannot function again, potentially threatening life. The prevalence of incidence and mortality depends on the progression of hepatic cirrhosis, which is influenced by the patient's etiology and treatment. The purpose of writing this article is to provide new insight into the importance of understanding the risk factor and causes of hepatic cirrhosis. This study uses a literature review approach by collecting data from online databases including Google Scholar, ProQuest, MDPI, and PubMed to search for articles discussing “Hepatic Cirrhosis”. Early detection based on clinical manifestations and appropriate treatment can reduce mortality and prevent complications that may worsen the patients condition.

Abstract

UV radiation from sunlight can induce the formation of free radicals, which can disrupt cellular homeostasis or DNA by triggering inflammatory signal transduction. The occurrence of inflammation in the skin can be aggravated by the presence of the bacterium Staphylococcus aureus. Previous studies have shown that the marine sponge Stylissa sp. contains an abundance of fatty acids and lipids compared to other species. Although Stylissa sp. has great potential for health applications, research on the bioactivity of lipid and fatty acid compounds from this sponge remains limited. Therefore, this study aims to explore the lipid content of Stylissa sp. as an alternative source of antibacterial agents against pathogens responsible for photoaging. The metabolite profiling of the extract was conducted using GC-MS, while the antibacterial activity was performed using the Kirby-Bauer method. Based on GC-MS profiling results, six compounds were identified in the lipid extract of Stylissa sp. namely palmitic acid, butyl glycol acetate, n-eicosylcyclohexane, isopropyl laurate, oleic acid, and 1-tetradecanol. Antibacterial evaluation of Stylissa sp. lipid extract at concentrations of 25%, 75%, and 100% showed antibacterial activity against Staphylococcus aureus, with inhibition zone diameters of 1.83, 2.17, and 2.92 mm, respectively. The results in this study have shown that the lipid extract of Stylissa sp. contains lipid compounds with potential anti-bacterial activity towards S. aureus. Future research to isolate unsaturated fatty acid compounds from the lipid extract of Stylissa sp. to achieve higher antibacterial activity is recommended.

Abstract

A health problem associated with increasing antibiotic resistance, the silent pandemic kills 700,000 people a year, mostly in Asia and Africa. In the case of probiotic or lactic acid bacteria, antibiotic resistance can enhance nutrient absorption in the host and prevent the colonization of pathogenic bacteria. To address this, the WHO has suggested using the One Health Tricycle strategy, which entails monitoring people, the environment, and animals. One facet of this investigation is animals, specifically chickens. This study aims to identify the antibiotic resistance and profile of cefotaxime-resistant lactic acid bacteria (LAB) from broiler chicken cecum. Isolating LAB from the chicken's cecum is one of the techniques employed. After calculating the prevalence of resistant bacteria, the bacteria were characterized as macroscopic, microscopic, and biochemically. Testing the antibiotics against LAB was the next stage. According to the study's findings, the bacterial colonies were tiny to medium-sized, white, spherical, and convex, with complete margins. Gram-positive bacilli were identified by Gram staining. The findings of the biochemical tests were negative for oxidative and catalase, positive for glucose, and negative for other biochemical tests. According to antibiotic sensitivity testing, LAB was 90.9% resistant to Vancomycin, 63.63% to Chloramphenicol, and 100% to Erythromycin, Aztreonam, and Ceftriaxone. According to these findings, LAB in the chicken caecum has become resistant to several antibiotics. To give a better picture of the balance between pathogenic and helpful bacteria in the chicken cecum, more LAB testing against pathogenic bacteria is required.

Abstract

Pineapple (Ananas comosus (L.) Merr) is empirically used as a medicine to cure constipation, nausea, urinary tract disorders, flu, and various skin diseases. Secondary metabolites that cause this activity are alkaloids, tannins, flavonoids, saponins and triterpenoids. Secondary metabolite phytochemical screening has been carried out on pineapple peel juice and freeze-dried pineapple peel powder, but no tests have been carried out on dehydrated pineapple peel powder. The primary objective of this study was to determine of secondary metabolites in pineapple peel water extract. The powdered pineapple peel extract was made using pineapple peel juice that had been dried in a dehydrator at 40ºC for two 24-hour cycles. Phytochemical screening makes use of a tube test, which involves qualitative observation using separate reagents for each chemical. Alkaloids, flavonoids, quinones, tannins, and triterpenoids were found in pineapple skin as secondary metabolites, but saponin chemicals were found to be absent.
