Authors: Surbakti Christica Ilsanna , Tarigan Modesta , Ginting Grace Anastasia
Published: August 2023

Latar Belakang : Biji pepaya memiliki kandungan vitamin C, Vitamin E dan nutrisi penting lainnya yang dipercaya dapat melindungi kesehatan mata dan mecegah berbagai penyakit .Pada biji pepaya (Carica papaya L.) adanya rasa pahit disebabkan oleh kandungan alkaloid carpain. Carpain merupakan suatu alkaloid golongan alkaloid bebas. Alkaloid carpain ini dapat menurunkan tekanan darah, membunuh amuba, kencing batu, penyakit saluran kencing, dan cacing. Namun sering dijumpai obat tradisional yang tidak menghasilkan efek yang diharapkan, umumnya dikarenakan tidak memenuhi standar mutu atau bisa juga dikarenakan kesalahan informasi maupun anggapan keliru terhadap obat tradisional. Dari segi efek samping memang diakui bahwa obat tradisional memiliki efek samping yang relatif kecil dibanding obat modern. Oleh karena itu, peneliti tertarik untuk membuat ekstrak yang bermutu dan berkhasiat, dengan demikian produk-produk herbal tersebut dapat terjaga kualitas, mutu dan khasiatnya yang dapat menyembuhkan berbagai penyakit. Tujuan :Untuk mengetahui jumlah persen rendemen perolehan ekstrak setelah dilakukan ekstraksi biji pepaya secara maserasi, hasil identifikasi metabolit sekunder dan karakterisasi dari biji papaya dengan menggunakan pelarut etanol 70%.

Authors: Musthafa Muhamad Yusuf , Chozin Iin Noor , Setyawan Ungky Agus , Sardjono Teguh Wahyu , AS Noorhamdani
Published: August 2023

Background: Gradually, fungal infections are growing and have become a medical concern. Candida species are one of the most common pathogens in immunocompromised patients, such as those with lung cancer causing invasive fungal disease. Early diagnosis of candidiasis is critical for patient care in lung cancer patients. Anti-mannan IgM and IgG biomarkers are used to diagnose candidiasis. This study aims to determine the relationship between chemotherapy status, absolute lymphocyte count, and neutrophil-lymphocyte ratio to antimannan IgM and IgG.Methods: A correlative analytic cross-sectional study was conducted on 37 lung cancer patients with positive candida sputum cultures in Dr. Saiful Anwar Malang Hospital. The 37 patients were examined for total lymphocyte level, neutrophil-lymphocyte ratio, anti-mannan IgM, and IgG. Data analysis used a contingency coefficient to determine the relationship between chemotherapy status, absolute lymphocyte count, and neutrophil-lymphocyte ratio to anti-mannan IgM and IgG.Results: This study showed a positive correlation between chemotherapy status with anti-mannan IgM and IgG, although insignificant (p>0.05). However, there was a significant correlation between total lymphocytes and anti-mannan IgG (p=0.000;α=0.05) and between neutrophil-lymphocyte ratio and antimannan IgM (p=0.004; α=0.05).Conclusion: The study revealed that chemotherapy status, absolute lymphocyte count, and neutrophil-lymphocyte ratio could be a biomarker of candidiasis, so lung cancer patients with a history of chemotherapy, lymphopenia, and increased neutrophil-lymphocyte ratio should consider receiving antifungals earlier.
Primary Spontaneous Pneumothorax In Healthy Tall and Thin Male Secondary to Smoking: A Case Report and Literature Review
Authors: Yanti Budi , Marlena Rina
Published: August 2023

Background: Primary Spontaneous Pneumothorax (PSP) refers to the collapse of a lung without any underlying disease and is commonly observed in tall, thin young men, with smoking as an under-recognized risk factor. The management of PSP can vary significantly across different health centers. This case report highlights a young man with a pneumothorax without an underlying illness but has a smoking habit who initially gets treatment with an insertion of a chest tube.Case: This study focused on a 19-year-old man complaining of sudden right chest pain. The patient was a smoker for the past four years, and the examination showed hypersonic and vesicular loss on the right side. The laboratory tests revealed normal limits, and the sputum indicated the absence of tuberculosis. Chest X-ray showed an avascular radiolucent area in the right lung, and a Chest CT scan confirmed the presence of a hypodense area of air density in the right hemithorax. Right PSP was diagnosed and managed using a chest tube drainage on admission. After four days of treatment, he exhibited improvement and was discharged. A recurrence of pneumothorax was not discovered in the subsequent six-month follow-up period.Conclusion: Despite being a rare disorder, PSP should be considered during the physical examination of patients. It is also important to reassess the risk factors that can contribute to the onset of pneumothorax. The clinicians should be able to identify PSP and emphasize tall, thin, and young men at greater risk of pneumothorax in a pulmonary emergency.

Published: August 2023

The objective of this study was to investigate the effect of rosemary leaves powder supplement on reproductive and productive performance of local pigeon. Thirty pairs of Libyan local pigeons were randomly allocated into three groups, each with 10 replicates. Rosemary leaves powder (RLP) was added to isonitrogenous and isoenergetic ration at 0 % (control, C), 0.5 % (T1) or 1 % (T2). The experiment lasted for a complete breeding cycle. RLP did not affect egg weight, egg number or incubation period. Egg volume (13.82, 10.73 and 11.42 cm3), egg hatchability (100, 55.56 and 50.00 %) and hatching weight (16.63, 14.91 and 14.89 g) were higher in C group in comparison with T1 and T2, respectively (p < 0.05). Egg surface area (30.25, 26.30 and 27.74 cm2) and egg width (2.67, 2.44 and 2.53 cm) were higher in C than in T1 (p < 0.05) and tended to be higher than T2 (p > 0.05). Egg length, egg shape index, fertility rate and pre-weaning survival rate tended to decrease with the increased RLP inclusion rate; however, these differences were not significant (p > 0.05). Squab weight at weaning was lower in C than in T2 group, (310.35, 312.08, 337.98 g for C, T1, and T2, respectively) (p < 0.05). Peroxide value of fresh meat tended to decrease in T2 compared to T1 or C groups (0.6, 0.49, 0.37 meq/kg for C, T1 and T2, respectively) (p > 0.05). Malondialdehyde (MDA) concentration in fresh meat (0.16, 0.16, 0.09 mg MDA/kg) and blood (1.66, 0.83, 0.61 mg MDA/L) for C, T1 and T2, respectively, was lower in T2 compared to C group (p < 0.05). In conclusion, adding RLP to feed negatively affected the reproductive performance despite expected improvement of the productive performance and oxidative status in pigeons.

Published: August 2023

Table eggs collected at random from one-hundred and fifty layers (75-FUNAAB-Alpha and 75- ISA brown) kept at Breeding Unit, Teaching and Research Farm, Olusegun Agagu University of Science and Technology, Okitipupa at 31st, 33rd, and 35th weeks (WK) of age were analyzed for internal and external characteristics within 24 hours of laying. The data collected were subjected to analysis of variance to assess the effect of breed and age of the layers on egg quality. Breed had no significant effect (p > 0.05) on the egg weight (Ewt), egg length (EL), shell weight (SW), shell ratio (SR), albumen weight (AW), albumen ratio (AR), yolk diameter (YD) and yolk height (YH) in all the ages considered. At WK 31 breed effect was observed (p < 0.05) in egg width (EW), shell index (SI), yolk weight (YW), yolk ratio (YR), albumen height (AH) and haugh unit (HU), and higher values were observed in all the traits for ISA brown except yolk weight (YW) and yolk ratio (YR). Significant effect of breed (< 0.05) was observed in HU and AH at WK33. Shell thickness (ST) and yolk index (YI) experienced breed effect at WK 35. Breed and age had no effect on nutritional compositions of eggs. It can be concluded that breed and layer's age do have effects on some egg quality parameters.

Authors: STAROŇ Martin , KŇAZOVICKÁ Vladimíra , GASPER Jaroslav
Published: August 2023

The aim of the study was to monitor the changes in the free acidity of honey after administration of three anti-varrotic treatments with the use of formic acid (FA), oxalic acid (OA) and essential oils as the active substances in commercial preparation. To the first experimental group, 60 % FA was administered by vaporization using the vaporizer Nassenheider Professional® (group F). OA was administered by the contact in the form of 26.8 % (w/w) glycerine solution of OA on special workshop towels (group O). Essential oils were administered in the form of the commercial product Bisanar® (group B). The control group received no treatment during the experiment. Although the acidity of the honey in the B group during the experiment did not show significant difference compared to the control group (p = 0.769) and only a slight difference was determined in the O group (p = 0.416), the F group showed significant increase of the values compared to the control group (p = 0.015). The average value of free acidity in honey of this experimental group did not decrease notably under the legislative limit after two weeks following removing the treatment from the hive. Free acidity in the F group reached the value of 57.50 ± 25.19 mEq/kg (milliequivalents per kg) at the end of the experiment. Treatments by OA and Bisanar® are more suitable to supress varroosis during the summer without significant increase of free acidity in honey.

Published: August 2023

The efficacy of varying levels of mycotoxin binder supplementation on growth performance, carcass characteristics and serum metabolites of broiler chickens fed aflatoxin maize-based diets was assessed. A total of four hundred and thirty-two (432), one-day-old Hubbard Cobb hybrid broilers were used for the experiment. The chicks were equally weighed and allotted to 12 dietary treatments in a 3 x 4 factorial arrangement of an activated clay toxin binder at three different inclusion levels (0 g/kg, 0.1 g/kg and 0.2 g/kg) of feed challenged with 4 levels of aflatoxin B, (0, 40, 60 and 80 ppb). Thirty-six chicks were allocated to each treatment group and replicated three times with 12 chicks per replicate in deep litter for eight weeks. At the end of the feeding trial, the birds were starved overnight prior to blood collection, three birds per treatment were selected on the basis of average pen weight. Blood samples were collected for serum and haematological analysis. Data collected were subjected to One-way analysis of variance (ANOVA) using SAS software. Results revealed significant (p < 0.05) differences in the total protein (TP) content across the dietary treatments. Interaction between aflatoxin and binder levels showed a significant (p < 0.05) effect only on the Alanine amino transferase (ALT) of the birds. Addition of mycotoxin binder (clay type) to aflatoxin contaminated diets was able to ameliorate the effect of aflatoxin on birds regardless of the level at which it was supplemented. Inclusion of 1 % binder in the diets is therefore recommended and feed ingredients for feed formulations be always subjected to test for aflatoxins.

Published: August 2023

4-thiazolidinones are five-membered heterocyclic ring compounds with diverse pharmacological impacts. In a previous study, we reported a series of newly synthesized derivatives of 4-thiazolidinones with different functional groups, which exhibited anticancer activity against ovarian (SKOV3) and cervical (HeLa) cancer cell lines. Among these derivatives, (4-fluorophenyl) thiazolidin-4-one (4-TH) demonstrated potent cytotoxic activity against SKOV3, with an IC50 value of 12.3 μM. However, it was also found to be extremely toxic to normal cells (CHO-K1) with an IC50 of 7.5 μM. Before considering its use in cancer research, it is crucial to gain a comprehensive understanding of its potential genotoxic effects on normal cells. In this study, we aimed to assess the in vitro cytogenetic toxicity of 4-TH using normal Chinese hamster ovary cells (CHO-K1). Referring to the IC50 of 4-TH, we selected three sub-lethal concentrations (2, 5, and 7.5 μM) and treated CHO-K1 cells for 24 h (one cell cycle duration) to estimate its dose-dependent induction of chromosome aberrations, and examine the effect of 4-TH on cell division, micronucleus induction potential and cell cycle arrest properties following standard protocols. The results showed that 4-TH was highly toxic to normal cells, as all three sublethal concentrations caused a statistically significant increase in the number of chromosomal aberrations (P < 0.001), formation of micronuclei (P < 0.01), and changes in the rate of cell division (mitotic index) (P < 0.05) compared to control. In addition, there was a significant increase in the number of cells in the G1 phase, indicating that all concentrations of 4-TH tested induced apoptosis. The evaluation of the cytotoxic, clastogenic, and aneugenic properties of 4-TH, a potent cytotoxic agent, will undoubtedly provide critical information for determining its safety and potential as an anticancer drug.
Abnormal elevation of serum amylase in a patient with acute depression in a state of sub-stupor: A case report
Authors: Wang Qiang , Zhao Peng , Cao Qiuyun , Li Yi , Lu Rong , Yao Zhijian
Published: August 2023

Serum amylase predominantly comprises pancreatic and salivary amylases and its elevation is commonly associated with pancreatitis and other physical diseases. This case report presents a 63-year-old male with first-episode depression who exhibited abnormally elevated serum amylase. Shortly after admission, the patient entered a sub-stupor state. The patient developed symptoms such as high fever and excessive sweating on the second night. In addition, myocardial damage was observed. The serum amylase was found to be elevated in the morning on the 3rd day. Following symptomatic and supportive treatments, the patient’s serum amylase level gradually dropped to drop to normal over approximately 2 weeks. On careful analysis of the patient’s medical condition, we suspect the increased serum amylase level may be linked to his psychiatric symptoms. Based on this case, we speculate that besides physical illness, the stupor symptoms observed in patients with depression may also lead to elevated serum amylase. Therefore, clinicians must prioritize addressing psychiatric symptoms when encountering such situations.

Inversion Sequences Avoiding a Triple of Patterns of 3 Letters
Authors: Callan David , Jelínek Vít , Mansour Toufik
Published: August 2023

An inversion sequence of length $n$ is a sequence of integers $e=e_1\cdots  e_n$ which satisfies for each $i\in[n]=\{1,2,\ldots,n\}$ the inequality $0\le e_i < i$. For a set of patterns $P$, we let $\mathbf{I}_n(P)$ denote the set of inversion sequences of length $n$ that avoid all the patterns from~$P$. We say that two sets of patterns $P$ and $Q$ are I-Wilf-equivalent if $|\mathbf{I}_n(P)|=|\mathbf{I}_n(Q)|$ for every~$n$. In this paper, we show that the number of I-Wilf-equivalence classes among triples of length-3 patterns is $137$, $138$ or~$139$. In particular, to show that this number is exactly $137$, it remains to prove $\{101,102,110\}\stackrel{\mathbf{I}}{\sim}\{021,100,101\}$ and $\{100,110,201\}\stackrel{\mathbf{I}}{\sim}\{100,120,210\}$.

Published: August 2023

A balanced edge-coloring of the complete graph is an edge-coloring such that every vertex is incident to each color the same number of times. In this short note, we present a construction of a balanced edge-coloring with six colors of the complete graph on $n=13^k$ vertices, for every positive integer $k$, with no rainbow $K_4$. This solves a problem by Erdős and Tuza.
