However, there is insufficient evidence to recommend a particular type of protein to slow down the CKD progression. Recently, various plant-based diets could demonstrate some additional benefits such as a blood pressure-lowering effect, a reduction of metabolic acidosis as well as hyperphosphatemia, and gut-derived uremic toxins. Furthermore, the former concerns about the risk of undernutrition and hyperkalemia observed with plant-based diets may be inconsistent in real clinical practice. In this review, we summarize the current evidence of the proposed pleiotropic effects of plant-based diets and their associations with clinical outcomes among pre-dialysis CKD patients.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/abm-2024-00022024-03-20T00:00:00.000+00:00Management of ectopic pregnancy after in vitro fertilization/intracytoplasmic sperm injection and embryo transfer: a case series and mini-reviewhttps://sciendo.com/article/10.2478/abm-2024-0004<abstract> <title style='display:none'>Abstract</title> <sec><title style='display:none'>Background</title><p>Ectopic pregnancy (EP), reflecting a fertilized ovum implanted outside the normal uterine cavity, represents a frequent cause of morbidity and possibly mortality in women of reproductive age.</p></sec> <sec><title style='display:none'>Objective</title><p>To summarize the diagnosis and treatment of EP after in vitro fertilization/intracytoplasmic sperm injection and embryo transfer (IVF/ICSI-ET).</p></sec> <sec><title style='display:none'>Methods</title><p>The medical records of patients who were diagnosed with EP after embryo transfer from 2017 to 2019, in a tertiary hospital were reviewed.</p></sec> <sec><title style='display:none'>Results</title><p>Of the 24 cases analyzed, 21 (87.5%) had fallopian tube involvement, while 2 (8.3%) and 1 (4.2%) had cornual and cervical pregnancies, respectively.

The POCT approach has succeeded in meeting the current demand for having diagnostic strategies that can provide fast, sensitive, and highly accurate test results without involving complicated procedures. This has been accomplished by introducing rapid bioanalytical tools or biosensors such as lateral flow assays (LFAs). The production cost of these tools is very low, allowing developing countries with limited resources to utilize them or produce them on their own. Thus, their use has grown in various fields in recent years. More importantly, LFAs have created the possibility for a new era of incorporating nanotechnology in disease diagnosis and have already attained significant commercial success worldwide, making POCT an essential approach not just for now but also for the future. In this review, we have provided an overview of POCT and its evolution into the most promising rapid diagnostic approach. We also elaborate on LFAs with a special focus on nucleic acid LFAs.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/abm-2023-00682023-12-28T00:00:00.000+00:00The dose of the normal saline pre-infusion and other risk factors for amphotericin B deoxycholate-associated acute kidney injuryhttps://sciendo.com/article/10.2478/abm-2023-0071<abstract> <title style='display:none'>Abstract</title> <sec><title style='display:none'>Background</title> <p>Conventional amphotericin B deoxycholate (AmBd) is the preferred amphotericin B formulation in countries with limited resources despite its nephrotoxicity.

Extracellular regulated protein kinases (ERK1/2) phosphorylation of H460 cells could be blocked both by IR alone and IR combined with KZ-001. IR combined with KZ-001 is able to inhibit ERK activation of A549 cells apparently. KZ-001 increased the proportion of G2 phase in irradiated cells from 21.24% to 32.22%. KZ-001 could also significantly increase the double-strand break damage cell ratio to more than 30% compared to the irradiation alone group.</p> </sec> <sec><title style='display:none'>Conclusions</title> <p>MEK1/2 inhibitor KZ-001 is a potential radiosensitizer for clinical applications.</p> </sec> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/abm-2023-00642023-10-26T00:00:00.000+00:00Effects of coenzyme Q10 in a propofol infusion syndrome model of rabbitshttps://sciendo.com/article/10.2478/abm-2023-0058<abstract> <title style='display:none'>Abstract</title> <sec><title style='display:none'>Background</title> <p>Coenzyme Q (CoQ) might be the main site of interaction with propofol on the mitochondrial respiratory chain in the propofol infusion syndrome (PRIS) because of the structural similarity between coenzyme Q10 (CoQ10) and propofol.</p> </sec> <sec><title style='display:none'>Aim</title> <p>To investigate the effects of CoQ10 on survival and organ injury in a PRIS model in rabbits.</p> </sec> <sec><title style='display:none'>Methods</title> <p>Sixteen male New Zealand white rabbits were divided into 4 groups: (1) propofol infusion group, (2) propofol infusion and CoQ10, 100 mg/kg was administered intravenously, (3) sevoflurane inhalation was administered, and (4) sevoflurane inhalation and CoQ10, 100 mg/kg intravenously, was administered. Arterial blood gas and biochemical analyses were repeated every 2 h and every 12 h, respectively. Animals that were alive on the 24th hour after anesthesia induction were euthanized.

The propofol + CoQ10 group had lower troponin T levels when compared with the propofol and sevoflurane groups (<italic>P</italic> &lt; 0.05). Administration of CoQ10 decreased total liver injury scores and total organ injury scores both in the propofol and sevoflurane groups.
