Effect of Adding Kaffir Lime Leaf Powder (Citrus hystrix) and Citronella Leaf Powder (Cymbopogon nardus) in Salted Egg on pH, Antioxidant, Moisture Content, and Organoleptics

Ardiyanti Rahma Setiawati, Dedes Amertaningtyas, Ahmad Khoirul Umam · 2025 · Jurnal Ilmu dan Teknologi Hasil Ternak

Salted egg is a well-known traditional product, particularly in many Asian countries, where it is valued for its unique savory taste, extended shelf life, and convenience. Consumer demand for healthier, more appealing food has sparked interest in enriching salted eggs with natural ingredients. The purpose of this study was to analyze the effect of adding kaffir lime leaf powder (Citrus hystrix) and citronella leaf powder (Cymbopogon nardus) to salted eggs on pH, antioxidants, moisture and organoleptics. The research method used was experimental using a completely randomized design (CRD) with 6

Impact of cancer cachexia on the therapeutic outcome of combined chemoimmunotherapy in patients with non-small cell lung cancer: a retrospective study

Kenji Morimoto, Junji Uchino, Takashi Yokoi et al. · 2021 · OncoImmunology

Although previous studies suggest that cancer cachexia is a poor prognostic factor for immune checkpoint inhibitor monotherapy, the impact of cancer cachexia on chemoimmunotherapy is unclear. We investigated the impact of cancer cachexia on the therapeutic outcomes of chemoimmunotherapy for non-small cell lung cancer (NSCLC). We retrospectively analyzed patients’ medical records with NSCLC who received chemoimmunotherapy in 12 institutions in Japan between January and November 2019. We defined cancer cachexia as weight loss exceeding 5% of the total body weight or a body mass index of < 20 kg/

Parameters of radical resection in laparoscopic and open colon and rectal cancer surgery

Krdžić Igor, Kenić Marko, Šćepanović Milena et al. · 2020 · Vojnosanitetski Pregled

Background/Aim. In colon and rectal cancer surgery, resection is considered radical when circumferential, proximal and distal resection margins are without the presence of tumor cells. Concept of total mesorectal excision in rectal surgery involves complete removal of the tumor with mesorectal fascia which surrounds lymph nodes, lymphatics and blood vessels. The aim of this study was to determine whether laparoscopic approach provides all parameters of oncological radicality as open surgery of colorectal cancer. Methods. The study included 122 patients with carcinoma of colon and rectum, divid

Biological sex-related differences in whole-body coordination during standing turns in healthy young adults

Fuengfa Khobkhun, Jenjira Thanakamchokchai · 2023 · Scientific Reports

Abstract Biological sexes (male and female) have been reported to influence postural control and balance due to differences in musculoskeletal structures, hormonal factors, and neuromuscular control. These factors can contribute to the turning performance, potentially leading to an increased incidence of falls, particularly during turning. Therefore, this study aimed to explore the whole-body coordination and stepping characteristics and during standing turns in healthy adults to determine the effects of biological sex and turn speed. Fifty participants (25 males and 25 females) completed 180°

The role of trust in the social heuristics hypothesis.

Andres Montealegre, William Jimenez-Leal · 2019 · PLoS ONE

According to the social heuristics hypothesis, people intuitively cooperate or defect depending on which behavior is beneficial in their interactions. If cooperation is beneficial, people intuitively cooperate, but if defection is beneficial, they intuitively defect. However, deliberation promotes defection. Here, we tested two novel predictions regarding the role of trust in the social heuristics hypothesis. First, whether trust promotes intuitive cooperation. Second, whether preferring to think intuitively or deliberatively moderates the effect of trust on cooperation. In addition, we examin

Abstract The optimal surgical approach for elderly patients with early-stage non-small cell lung cancer (NSCLC) remains a topic of debate. A retrospective analysis was conducted on patients who underwent pulmonary resection for early-stage NSCLC at our single institution between January 2018 and December 2022. Propensity score matching was used to balance baseline characteristics between the sublobar resection and lobectomy groups. Perioperative outcomes, pulmonary function recovery, postoperative quality of life, and survival were compared between the two groups. A total of 151 patients were

Palatability of Norway spruce needles infected with Lophodermium piceae to larvae of two sawfly species

Unequivocal evidence on the antagonistic effects of endophytic fungi associated with woody plants against insect herbivores has been documented in only a few cases so far. Experimental evidence of the significance of needle endophytes to coniferous trees has remained scant because it is difficult to obtain trees with needles free of endophytes that could be used as comparable controls for trees infected with endophytes. Previously we reported a new methodology to get Norway spruce (Picea abies (L.) Karst.) saplings without needle endophytes and to inoculate them with a needle endophyte Lophode
