Interleukin-34 (IL-34) plays a role in the induction and differentiation of osteoclasts. Other inflammatory factors are not directly involved in the induction and differentiation, but play an indirect role by modulating the level of receptor activator of nuclear factor-κB (RANKL) and other molecules during the process of inflammatory bone destruction in AS. However, to our knowledge, the relationship between enthesitis and bone erosion, and IL-34 and RANKL in AS has not yet been elucidated.</p> </sec> <sec><title style='display:none'>Objective</title> <p>To determine the correlation between serum IL-34, RANKL, and disease severity including enthesitis and bone erosion in patients with AS and develop multivariable predictive model.</p> </sec> <sec><title style='display:none'>Methods</title> <p>We conducted a cross-sectional study of 40 patients with AS, compared with 40 patients with osteoarthritis, and 40 healthy volunteers. Their serum levels of IL-34 and RANKL were measured using enzyme-linked immunosorbent assays (ELISAs). Enthesitis and bone erosion were assessed with real-time ultrasonography. Spearman rank correlation coefficients were determined to analyze the relationship between the variables.

Serotonin (5-hydroxytryptamine) receptors subtype 2B (HTR2B) play an essential role in cardiac function and development, and their overexpression in rats leads to myocardial hypertrophy. Epigallocatechin gallate (EGCG) is cardioprotective in myocardial ischemia–reperfusion injury in rats and can prevent pressure overload-mediated cardiac hypertrophy in vivo. Mice deficient in peroxisome proliferator-activated receptor delta (PPARδ) can have cardiac dysfunction, myocardial hypertrophy, and heart failure. Matrix metalloproteinases (MMPs) are possibly involved in cardiac remodeling. However, the relationship between IL-18 signaling, cardiac hypertrophy, and the molecular mechanisms involved remain to be fully elucidated.</p> </sec> <sec><title style='display:none'>Objectives</title> <p>To elucidate the relationship between HTR2B and IL-18-induced myocardial hypertrophy and examine the antihypertrophic effects of EGCG and PPARδ.</p> </sec> <sec><title style='display:none'>Methods</title> <p>We induced H9c2 cardiomyoblast hypertrophy with IL-18 in vitro and investigated the downstream signaling by real-time polymerase chain reaction (PCR) and western blotting.

IL-18 upregulated the expression of HTR2B, which was inhibited by pretreatment with EGCG and L-165,041. SB215505 (0.1 μM), a HTR2B antagonist and siRNA for HTR2B, attenuated H9c2 hypertrophy significantly.

Locomotor activity was measured 24 h after the final drug treatments, and subsequently their learned behavioral response to an adverse electrical stimulus to their plantar paw surface in a dark compartment was measured using a passive avoidance apparatus (Ugo Basile) in a model of impaired memory and cognition associated with Alzheimer disease. To determine any deficit in their learned avoidance of the adverse stimulus, we measured the initial latency or time mice spent in an illuminated white compartment before entering the dark compartment in the learning trial, and on the day after learning to avoid the adverse stimulus, the retention period latency in the light compartment and time spent in the dark compartment.</p> </sec> <sec><title style='display:none'>Results</title> <p>Atorvastatin alone produced no significant change in blood glucose levels (<italic>F</italic><sub>4,10</sub> = 0.80, <italic>P</italic> = 0.55) within 2 h.

Racemates of a drug with either an inactive or an unsafe enantiomer can lead to detrimental effects. The manufacturing industry may still produce racemates, but such decisions must pass through rigorous analyses of the pharmacological and pharmacokinetic characteristics of the particular enantiomer related to the racemates. The pharmacokinetics of antidepressants or antidepressive agents is stereoselective and predominantly favors one enantiomer. The use of pure enantiomers offers (i) better specificity than the racemates in terms of certain pharmacological actions, (ii) enhanced clinical indications, and (iii) optimized pharmacokinetics. Therefore, controlling the stereoselectivity in the pharmacokinetics of antidepressive drugs is of critical importance in dealing with depression and psychiatric conditions. The objective of this review is to highlight the importance of the stereochemistry of antidepressants in the context of the design and development of new chirally pure pharmaceuticals, the potential complications caused by using racemates, and the benefits of using pure enantiomers.</p> </abstract>ARTICLE2022-04-29T00:00:00.000+00:00Diagnostic accuracy of complete blood cell count and neutrophil-to-lymphocyte, lymphocyte-to-monocyte, and platelet-to-lymphocyte ratios for neonatal infectionhttps://sciendo.com/article/10.2478/abm-2022-0006<abstract> <title style='display:none'>Abstract</title> <sec><title style='display:none'>Background</title> <p>Complete blood cell (CBC) counts and neutrophil-to-lymphocyte (NLR), lymphocyte-to-monocyte (LMR), and platelet-to-lymphocyte ratios (PLR) are simple measurements that are conducted as part of routine diagnostic procedures.</p> </sec> <sec><title style='display:none'>Objective</title> <p>To determine the diagnostic importance, specificity, and sensitivity of these measurements for the diagnosis of neonatal infections and in discriminating between neonatal sepsis and various other infections.</p> </sec> <sec><title style='display:none'>Methods</title> <p>We conducted a retrospective study of data from a consecutive series of 232 neonatal patients admitted to Yildirim Beyazit University Yenimahalle Training and Research Hospital in Ankara for 2 years from 2016 to 2018.

After protein profiling, genetic screening, and mutation studies, scientists now have turned their attention to epigenetic modulation. This new arena has brought to light the world of noncoding RNA (ncRNA). Although very complicated and often confusing, ncRNA domains are now among the most attractive molecular markers for epigenetic control of cancer. Long ncRNA and microRNA (miRNA) have been studied best among the noncoding genome and huge data have accumulated regarding their inhibitory and promoting effects in cancer. Another sector of ncRNAs is the world of PIWI-interacting RNAs (piRNAs). Initially discovered with the asymmetric division of germline stem cells in the <italic>Drosophila</italic> ovary, piRNAs have a unique capability to associate with mammalian proteins analogous to P-element induced wimpy testis (PIWI) in <italic>Drosophila</italic> and are capable of silencing transposons. After a brief introduction to its discovery timelines, the present narrative review covers the biogenesis, function, and role of piRNAs in lung cancer. The effects on lung cancer are highlighted under sections of cell proliferation, stemness maintenance, metastasis, and overall survival, and the review concludes with a discussion of recent discoveries of another class of small ncRNAs, the piRNA-like RNAs (piR-Ls).</p> </abstract>ARTICLE2022-02-28T00:00:00.000+00:00Multivariable analysis of clinical and laboratory data manifestations predicting severity and mortality risk in patients with Coronavirus disease 2019 in the mountainous west of Iran: a retrospective single-center studyhttps://sciendo.com/article/10.2478/abm-2022-0005<abstract> <title style='display:none'>Abstract</title> <sec><title style='display:none'>Background</title> <p>Few reports have addressed the clinical and laboratory features of patients with coronavirus disease-2019 (COVID-19) in mountainous areas, especially in Iran.</p> </sec> <sec><title style='display:none'>Objectives</title> <p>To report the clinical and laboratory data and manifestations predicting mortality of patients with COVID-19 in the west of Iran.</p> </sec> <sec><title style='display:none'>Methods</title> <p>We conducted a retrospective cohort study of 286 patients hospitalized with COVID-19 between 25 February 2020 and 12 May 2020 to describe their clinical symptoms and laboratory test findings when they were admitted at the Hajar Hospital affiliated with the Shahrekord University of Medical Sciences, and a multivariable analysis of factors that predict their disease severity and mortality.</p> </sec> <sec><title style='display:none'>Results</title> <p>After hospital admission, 18 patients died and 268 were discharged.

The bleeding tendency is typically associated with the shock phase of infection, for which blood replacement may be needed. However, repetitive blood transfusion can lead to volume overload. Administration of recombinant activated factor VII (rFVIIa) might be used to counteract bleeding without inducing volume overload. We describe the case of a patient with severe dengue infection who presented with intractable bleeding; he was initially treated with massive blood transfusions, which resulted in volume overload. He was then treated with rFVIIa to reverse the bleeding. During the second week of his hospitalization, his hematocrit dropped precipitously, and autoimmune hemolytic anemia was diagnosed. Supportive treatment was provided until recovery. Autoimmune hemolytic anemia is a rare complication in adult patients with dengue. Supportive care was effective for this atypical complication.</p></abstract>ARTICLE2021-02-21T00:00:00.000+00:00Gene polymorphisms and diseases in Asianshttps://sciendo.com/article/10.5372/1905-7415.0905.428ARTICLE2017-01-31T00:00:00.000+00:00CT features of normal lung change in asymptomatic elderly patientshttps://sciendo.com/article/10.5372/1905-7415.0905.431<abstract><title style='display:none'>Abstract</title><sec id="j_1905-7415.0905.431_s_001_w2aab3b7b3b1b6b1aab1c17b1Aa"><title style='display:none' id="d574916e16891_w2aab3b7b3b1b6b1aab1c17b1aAa">Background</title><p>Not all morphological lung changes in the elderly contribute to respiratory disease and may be a consequence of normal aging.</p></sec><sec id="j_1905-7415.0905.431_s_002_w2aab3b7b3b1b6b1aab1c17b2Aa"><title style='display:none' id="d574916e16900_w2aab3b7b3b1b6b1aab1c17b2aAa">Objectives</title><p>To describe the changes in asymptomatic elderly patients compared with those in younger patients in a Thai population.</p></sec><sec id="j_1905-7415.0905.431_s_003_w2aab3b7b3b1b6b1aab1c17b3Aa"><title style='display:none' id="d574916e16909_w2aab3b7b3b1b6b1aab1c17b3aAa">Methods</title><p>The study cohort comprised 60 participants without respiratory symptoms in three groups of 20 by age: 20-40 years, 41-60 years, and &gt;60 years.
