Formulasi cuko pempek instan terbaik berdasarkan indeks efektivitas adalah penambahan tinta cumi-cumi 7%, yaitu kadar asam glutamat 3,55±0,01%, air 3,89±0,20%, protein 11,78±0,19% (bk), kecerahan (L*) 55,26±0,37, redness (a*) -3,43±0,09, yellowness (b*) 11,44±0,17, kelarutan 86,11±2,92%, dan rata-rata uji hedonik 3,10±0,29 dari skala 4,00.Cuko pempek is a traditional sauce originating from Palembang, characterized by its combination of sour, sweet, and spicy flavors.Cuko pempek can be prepared in an instant powdered form to offer a more extended shelf life, convenience, and ease of distribution. The objective of this study was to determine the optimal method for incorporating squid ink into instant cuko pempek in terms of chemical, physical, and sensory properties. An instant cuko pempek was prepared by incorporating squid ink at concentrations of 0%, 3%, 5%, and 7% (v/v). The instant cuko pempek was subjected to a drying process using the foam-mat drying method, which utilized 30% egg white and 10% maltodextrin. The drying process was performed at 60 °C for 4–8 h. The examination of the parameters assessed glutamic acid content, water content, protein content, color, solubility, and hedonic testing. According to the findings of this study, the incorporation of squid ink significantly affected (p<0.05) the attributes of instant cuko pempek, including glutamic acid content, water content, protein content, color, flavor, and taste, as evaluated through hedonic testing. The most effective formulation for instant cuko pempek was found to be the addition of 7% squid ink, with a glutamic acid content of 3.55±0.01%, water content of 3.89±0.20%, protein content of 11.78±0.19% (wb), lightness (L*) of 55.26±0.37, redness (a*) of -3.43±0.09, yellowness (b*) of 11.44±0.17, solubility of 86.11±2.92%, and average hedonic score of 3.10±0.29 on a scale of 4.00
The Effect of Pasteurization Temperature and Pasteurization Time on the Quality of Cuko Pempek: Pengaruh Suhu Pasteurisasi dan Lama Waktu Pasteurisasi Terhadap Kualitas Cuko Pempek
No full textCuko pempek is a critical component of traditional Palembang cuisine, but it is susceptible to microbiological contamination, which can lead to a quality decrease. Improper pasteurization processes can potentially alter the characteristics of cuko pempek, thereby affecting consumer acceptance. This study aims to determine the effect of temperature and pasteurization time on the characteristics of cuko pempek. The study used a factorial Randomized Block Design (RB), first factor is pasteurization temperature (60℃, 70℃, 80℃) and second factor is pasteurization time (10, 15, and 20 minutes). The results showed an interaction between temperature and pasteurization time on total acidity and pH. Treatment S1M3 with 0,68 total score was the best treatment (60℃ temperature with 20 minutes). The viscosity test results were 0.67N; TPT 41.67 mg/L; color L* 30.84; color a* 5.43; color b* 19.27; total acidity 1.42%; pH 4.67; TPC 1.5x10⁹; organoleptic color 3.70; aroma 3.77; taste 3.83; texture 3.73
Proliferation and Apoptosis of Cat (Felis catus) Male Germ Cells during Breeding and Non-Breeding Seasons
No full textThe domestic cat (Felis catus) is a seasonal-breeding species whose reproductive period starts when the day length increases. Since the existing information on cat spermatogenesis is limited and somewhat contradictory, in the present study, germ cell proliferation and apoptosis in feral adult tomcats orchiectomized during reproductive (reproductive group, RG; February–July) and non-reproductive (non-reproductive group, NRG; November and December) seasons were compared. Cross-sections taken from the middle third of the left testis were chemically fixed and embedded in paraffin wax. Histological sections were processed for the immunohistochemical detection of proliferating germ cells (PCNA) and for the identification of apoptotic cells (TUNEL method). The percentage of PCNA-positive spermatogonia was higher in the RG than in the NRG. On the contrary, germ cell apoptosis was higher in the NRG than in the RG. Our results confirm that cat spermatogenesis is modulated on a seasonal basis and suggests that spermatogenesis control involves changes in germ cell proliferation and apoptosis according to a common paradigm of seasonally breeding species
The Effect of Composite Brushing with Different Types of Toothpaste on Stain Due to Immersion in Coffee, Tea and Cuko Pempek Water
No full textABSTRACTComposite is a tooth-colored filling material that can change color by extrinsic staining such as coffee, tea and cuko pempek. Abrasive toothpaste can reduce stains but increase surface roughness. This study aims to determine the effect of the type of toothpaste for brushing on the formation of stains caused by coffee, tea and cuko pempek. This research is a quasi-experimental with pre and post control group design. 39 composite discs with a diameter of 1 cm and a thickness of 5 mm were prepared and divided into several groups, 1 group of negative control without treatment, 3 groups of immersion. Each immersion group was divided into 4 brushing groups, namely without brushing, brushing without toothpaste, brushing with abrasive paste and brushing with non-abrasive paste. Pre and post treatment discs were photographed and color changes were assessed using the CIE L*a*b and E system. Friedman, Kruskall Wallis and Mann Whitney U non-parametric analysis test was used to compare color values and color differences within groups and between groups. Based on this study, it can be concluded that there were significant color changes before and after the soaking treatment with coffee, tea and cuko pempek. The color change in coffee was significantly greater than that of tea and cuko pempek. There was no significant difference in color change between tea and cuko pempek. Conclusion: Brushing with toothpaste Keywords: composite; coffee; tea; cuko pempek; CIE LA
Hepatitis B, C and Delta virus infections in Albanian patients with chronic liver disease: evaluation of possible changes during the last 10 years
No full textObjective and methods The prevalence of viral hepatitis markers and of alcohol intake was evaluated in 106 and 99 Albanian patients with the diagnosis of viral and/or alcoholic chronic liver disease who were consecutively admitted to the University Hospital Center of Tirana, during 1995 and 2005, respectively. Results A slight decrease in HBsAg (78 vs. 70%) and HBeAg (18 vs. 12%) prevalences were observed in patients admitted to the hospital during 2005 compared with those admitted during 1995, respectively. In both periods of time, hepatitis B virus (HBV) DNA (genotype D) tested positive in all HBsAg-positive patients and in 36% of HBsAg-negative patients. Anti-hepatitis C virus (HCV) prevalence (mainly observed after 30 years of age) was 14 versus 11 %; anti-hepatitis Delta virus (HDV) prevalence (more frequently present in young age group patients) was 9 versus 7% during 1995 and 2005, respectively. Among patients who reported alcohol intake, alcoholic liver disease (HBsAg and anti-HCV negative) was diagnosed in 35 and in 57% of patients admitted during 1995 and 2005, respectively (P=0.05). Conclusion In Albanian patients with chronic liver disease, we have found that: (i) HBV remained the most important aetiologic factor of chronic liver disease; HDV and HCV prevalences were still low, (ii) in HBsAg-positive patients, HBeAg-negative chronic hepatitis prevailed, (iii) in HBsAg-negative patients, HBV DNA prevalence was high, (iv) during the last decade, an increased prevalence of alcohol intake in the aetiology of chronic liver disease was observed.

Male germ cell proliferation and apoptosis in sexually immature meagre Argyrosomus regius (Asso, 1801) treated with recombinant follicle stimulating hormone
No full textThe meagre Argyrosomus regius (Asso, 1801) is a marine fish species that has an increasing aquaculture production in Europe. Lowering the age at maturity of hatchery-produced juveniles would support meagre aquaculture by reducing time between generations in selective breeding programs and reducing industrial costs for broodstock maintenance. The aim of this work was to assess the effects of a treatment with recombinant follicle stimulating hormone (rFsh), produced in ovarian cells of Chinese hamsters, on male germ cell proliferation and apoptosis in sexually immature meagre. The rFsh-treated fish had higher gonadosomatic index, larger seminiferous tubules, more abundant luminal spermatozoa, a lower density of anti-PCNA positive single A spermatogonia, a higher density of anti-PCNA positive spermatocysts and a lower incidence of germ cell apoptosis than control groups. The present study demonstrated the effectiveness of the produced rFsh in stimulating testis development and spermatogenesis in pre-pubertal meagre. Moreover, the rFsh treatment proved to be highly efficient in removing the apoptotic block of spermatogenesis observed in juvenile meagre, allowing spermatogonial survival and progress towards meiosis. The administration of rFsh did not stimulate spermatogonial self-renewal, a process whose control still needs to be elucidated
A multicentre roadmap to restart elective cardiac surgery after COVID-19 peak in an Italian epicenter
No full textBackground: During the Italian Phase-2 of the coronavirus pandemic, it was possible to restart elective surgeries. Because hospitals were still burdened with coronavirus disease 2019 (COVID-19) patients, it was focal to design a separate “clean path” for the surgical candidates and determine the possible effects of major surgery on previously infected patients. Methods: From May to July 2020 (postpandemic peak), 259 consecutive patients were scheduled for elective cardiac surgery in three different centers. Our original roadmap with four screening steps included: a short item questionnaire (STEP-1), nasopharyngeal swab (NP) (STEP-2), computed tomography (CT)-scan using COVID-19 reporting and data system (CO-RADS) scoring (STEP-3), and final NP swab before discharge (STEP-4). Results: Two patients (0.8%) resulted positive at STEP-2: one patient was discharged home for quarantine, the other performed a CT-scan (CO-RADS: 75 years: odds ratio [OR]: 2.6; 95% confidence interval [CI]: 1.25–5.57; p = 0.011; CPB >90 min. OR: 4.3; 95% CI: 1.84–10.16; p = 0.001). At 30 days, no periprocedural contagion and rehospitalization for COVID-19 infections were reported. Conclusions: Our structured roadmap supports the safe restarting of an elective cardiac surgery list after a peak of a still ongoing COVID-19 pandemic in an epicenter area. Mild to moderate CT residuals of coronavirus pneumonia do not justify elective cardiac surgery procrastination
