- ArticleKasama T, Ohtsuka K, Sato M, Takahashi R, Wakabayashi K, Kobayashi K.Arthritis. 2010;2010:106202.Macrophage migration inhibitory factor (MIF) was originally identified in the culture medium of activated T lymphocytes as a soluble factor that inhibited the random migration of macrophages. MIF is now recognized to be a multipotent cytokine involved in the regulation of immune and inflammatory responses. Moreover, the pivotal nature of its involvement highlights the importance of MIF to the pathogenesis of various inflammatory disorders and suggests that blocking MIF may be a useful therapeutic strategy for treating these diseases. This paper discusses the function and expressional regulation of MIF in several rheumatic diseases and related conditions.
- ArticleHarnung Scholten R, Møller P, Jovanovic Andersen Z, Dehlendorff C, Khan J, Brandt J, Ketzel M, Knudsen LE, Mathiesen L.Environ Int. 2021 01;146:106202.Telomere length (TL) is a biomarker of biological aging that may be affected by prenatal exposure to air pollution. The aim of this study was to assess the association between prenatal exposure to air pollution and TL in maternal blood cells (leukocytes), placenta and umbilical cord blood cells, sampled immediately after birth in 296 Danish mother-child pairs from a birth cohort. Exposure data was obtained using the high-resolution and spatial-temporal air pollution modeling system DEHM-UBM-AirGIS for PM2.5, PM10, SO2, NH4+, black carbon (BC), organic carbon (OC), CO, O3, NO2, and NOx at residential and occupational addresses of the participating women for the full duration of the pregnancy. The association between prenatal exposure to air pollutants and TL was investigated using distributed lag models. There were significant and positive associations between TL in umbilical cord blood cells and prenatal exposure to BC, OC, NO2, NOx, CO, and O3 during the second trimester. TL in umbilical cord blood was significantly and inversely associated with prenatal exposure to PM2.5, BC, OC, SO2, NH4+, CO and NO2 during the third trimester. There were similar inverse associations between TL from umbilical cord blood cells and air pollution exposure at the residential and occupational addresses. There were weaker or no associations between air pollution exposure and TL in placenta tissue and maternal blood cells. In conclusion, both the second and third trimesters of pregnancy are shown to be sensitive windows of exposure to air pollution affecting fetal TL.
- ArticleParama D, Girisa S, Khatoon E, Kumar A, Alqahtani MS, Abbas M, Sethi G, Kunnumakkara AB.Pharmacol Res. 2022 05;179:106202.Chronic diseases are considered a major public health concern worldwide, and most of these diseases like cancer, cardiovascular, metabolic, and neurological disorders occur due to atypical regulation of multiple signaling pathways. It has also been observed that most of the currently approved therapies for these diseases fail to show prolonged efficacy due to their mono-targeted nature and are associated with the development of chemoresistance, thus restricting their utility. The plant-derived compounds, on the other hand, show multi-targeted nature, and thus these phytochemicals have gained wide attention as they offer negligible side effects. The present review aims to recapitulate the potential effects of one such phytochemical, Scopoletin, which was found to have a diverse range of pharmacological activities such as anti-cancer, anti-diabetic, anti-inflammatory, cardioprotective, hepatoprotective, etc. Scopoletin modulated multiple molecular signatures in cancer, including AMPK, EGFR, MAPK/ ERK, NF-κB, PI3K/Akt/ mTOR, and STAT3; regulated the levels of critical markers of metabolic diseases such as ALT, AST, TG, and TC; inflammatory diseases such as ILs and TNFs; neurological diseases such as AChE, etc. thus relieving the symptoms and severity associated with these diseases. Further, this compound has a non-toxic nature and possesses an excellent pharmacokinetic property, which warrants further investigation in clinical settings for developing it as a potential drug.
- ArticleChen S, Li H, Wang L, Du X, Dong GH.Addict Behav. 2020 03;102:106202.Although online gaming may lead to Internet gaming disorder (IGD), most players are recreational game users (RGU) who do not develop IGD. So far, the topological organization of whole-brain functional networks in IGD remains poorly understood. The inclusion of RGU as a control group could minimize the potential effects of gaming experience and gaming-related cue familiarity on the neural characteristics of IGD subjects. In the present study, we applied graph theoretical analysis to preliminarily explore the topological organization of intrinsic functional brain networks in IGD. 61 IGD participants and 61 matched RGU participants were recruited to undergo a resting-state functional magnetic resonance imaging scan. The whole-brain functional networks were constructed by thresholding partial correlation matrices of 90 brain regions, and graph-based approaches were applied to analysis their topological attributes, including small-world, efficiency, and nodal centralities. Both of IGD and RGU groups showed efficient and economic small-world topology in brain functional networks. Although there was no significant group difference in global properties, subjects with IGD as compared to those with RGU showed increased nodal centralities in the reward, craving, emotional memory and sensory-motor processing regions. These results suggest that the functional network dysfunction, characterizing by heightened incentive motivation and sensory-motor coordination, may provide a new perspective for understanding the neural characteristics underlying IGD.
- ArticleTaghipour A, Rahimpour A, Rastgar M, Sadrzadeh M.Ultrason Sonochem. 2022 Nov;90:106202.Metal-organic framework (MOF) membranes hold the promise for energy-efficient separation processes. These nanocrystalline compounds can effectively separate materials with different sizes and shapes at a molecular level. Furthermore, MOFs are excellent candidates for improving membrane permeability and/or selectivity due to their unique properties, such as high specific area and special wettability. Generally, MOFs can be used as fillers in mixed matrix membranes (MMMs) or incorporated onto the membrane surface to modify the top layer. Characteristics of the MOFs, and correspondingly, the properties of the MOF-based membranes, are majorly affected by their production technique. This critical review discusses the sonication technique for MOF production and the opportunities and challenges of using MOF for making membranes. Effective parameters on the characteristics of the synthesized MOFs, such as sonication time and power, were discussed in detail. Although the ultrasonically synthesized MOFs have shown great potential in the fabrication/modification of membranes for gas and liquid separation/purification, so far, no comprehensive and critical review has been published to clarify such accomplishments and technological gaps for the future research direction. This paper aims to review the most recent research conducted on ultrasonically synthesized MOF for the modification of polymeric membranes. Recommendations are provided with the intent of identifying the potential future works to explore the influential sonication parameters.

The positive rate, sensitivity, and negative predictive values of the modified CFW method were all significantly higher than those of traditional fungal culture and KOH methods.
- ArticlePorciuncula LM, Teixeira AR, Santos MFC, D'Oca MGM, Orth ES, D'Oca CRM.Data Brief. 2020 Oct;32:106202.This work describes the data collection of new lipophilic esters and amides herbicides, analogues to 2,4-dichlorophenoxyacetic acid (2,4-D) and Propanil. The data include 1H and 13C NMR spectra and UV-VIS spectroscopic experiments, from the work "Novel lipophilic analogues from 2,4-D and Propanil herbicides: Biological activity and kinetic studies". The UV-VIS and 1H NMR spectra were employed to kinetic degradation design, and could be used to access new herbicides derivatives with better environmental properties.
- ArticleLutshumba J, Wilcock DM, Monson NL, Stowe AM.Neurobiol Dis. 2023 08;184:106202.Neurological conditions such as Alzheimer's disease (AD) and related dementias (ADRD) present with many challenges due to the heterogeneity of the related disease(s), making it difficult to develop effective treatments. Additionally, the progression of ADRD-related pathologies presents differently between men and women. With two-thirds of the population affected with ADRD being women, ADRD has presented itself with a bias toward the female population. However, studies of ADRD generally do not incorporate sex-based differences in investigating the development and progression of the disease, which is detrimental to understanding and treating dementia. Additionally, recent implications for the adaptive immune system in the development of ADRD bring in new factors to be considered as part of the disease, including sex-based differences in immune response(s) during ADRD development. Here, we review the sex-based differences of pathological hallmarks of ADRD presentation and progression, sex-based differences in the adaptive immune system and how it changes with ADRD, and the importance of precision medicine in the development of a more targeted and personalized treatment for this devastating and prevalent neurodegenerative condition.
- ArticleSun C, Wu F, Fu Y, Wallis DJ, Mikhaylov R, Yuan F, Liang D, Xie Z, Wang H, Tao R, Shen MH, Yang J, Xun W, Wu Z, Yang Z, Cang H, Yang X.Ultrasonics. 2020 Dec;108:106202.Gallium nitride (GaN) is a compound semiconductor which shows advantages in new functionalities and applications due to its piezoelectric, optoelectronic, and piezo-resistive properties. This study develops a thin film GaN-based acoustic tweezer (GaNAT) using surface acoustic waves (SAWs) and demonstrates its acoustofluidic ability to pattern and manipulate microparticles. Although the piezoelectric performance of the GaNAT is compromised compared with conventional lithium niobate-based SAW devices, the inherited properties of GaN allow higher input powers and superior thermal stability. This study shows for the first time that thin film GaN is suitable for the fabrication of the acoustofluidic devices to manipulate microparticles with excellent performance. Numerical modelling of the acoustic pressure fields and the trajectories of mixtures of microparticles driven by the GaNAT was performed and the results were verified from the experimental studies using samples of polystyrene microspheres. The work has proved the robustness of thin film GaN as a candidate material to develop high-power acoustic tweezers, with the potential of monolithical integration with electronics to offer diverse microsystem applications.
- ArticleYang M, Xie J, Lei X, Song Z, Gong Y, Liu H, Zhou L.Int Immunopharmacol. 2020 Mar;80:106202.Type 2 diabetes mellitus is often companied with osteoporosis, a process which involves osteoclast activation. In this study, we found tubeimoside I, a natural compound isolated from the Chinese medicinal herb Bolbostemma paniculatum (Maxim) Franquet (Cucurbitaceae), significantly ameliorated the decrease of bone mass in type 2 diabetes-induced osteoporosis in rats. It appears that tubeimoside I exerts this protecting effect through inhibiting osteoclast formation and function. Futhermore, our study showed that tubeimoside I inhibits NF-κB transcriptional activation and degradation of IκBα. Collectively, our results reveal that tubeimoside I attenuates osteoclastogenesis through down-regulating NF-κB signaling pathway, and is a potential candidate for the treatment of bone-destructive diseases like type 2 diabetic osteoporosis.
- ArticleSandeep Kumar J, Naimisha R, Thirupataiah B, Sujeevan Reddy G, Bung N, Roy A, Bulusu G, Mishra A, Yadav PN, Misra P, Pal M.Bioorg Chem. 2022 Dec;129:106202.Efforts have been devoted for the discovery and development of positive allosteric modulators (PAMs) of 5-HT2CR because of their potential advantages over the orthosteric agonist like Lorcaserin that was withdrawn from the market. On the other hand, pursuing a positive ago-allosteric modulator (PAAM) is considered as beneficial particularly when an agonist is not capable of affecting the potency of the endogenous agonist sufficiently. In search of a suitable PAAM of 5-HT2CR we adopted an in silico based approach that indicated the potential of the 3-(1-hydroxycycloalkyl) substituted isoquinolin-1-one derivatives against the 5-HT2CR as majority of these molecules interacted with the site other than that of Lorcaserin with superior docking scores. These compounds along with the regioisomeric 3-methyleneisoindolin-1-one derivatives were prepared via the Cu(OAc)2 catalyzed coupling of 2-iodobenzamide with 1-ethynylcycloalkanol under ultrasound irradiation. According to the in vitro studies, most of these compounds were not only found to be potent and selective agonists but also emerged as PAAM of 5-HT2CR whereas Lorcaserin did not show PAAM activities. According to the SAR study the isoquinolin-1(2H)-ones appeared as better PAAM than isoindolin-1-ones whereas the presence of hydroxyl group appeared to be crucial for the activity. With the potent PAAM activity for 5-HT2CR (EC50 = 1 nM) and 107 and 86-fold selectivity towards 5-HT2C over 5-HT2A and 5-HT2B the compound 4i was identified as a hit molecule. The compound showed good stability in male BALB/c mice brain homogenate (∼85 % remaining after 2 h), moderate stability in the presence of rat liver microsomes (42 % remaining after 1 h) and acceptable PK properties with fast reaching in the brain maintaining ∼ 1:1 brain/plasma concentration ratio. The compound at a dose of 50 mg/kg exhibited decreased trend in the food intake starting from day 3 in S.D. rats, which reached significant by 5th day, and the effect was comparable to Lorcaserin (10 mg/kg) on day 5. Thus, being the first example of PAAM of 5-HT2CR the compound 4i is of further medicinal interest.
- ArticleMitsuboshi S, Imai S, Kizaki H, Hori S.J Infect. 2024 Jun 17:106202.OBJECTIVES: To determine whether concomitant use of ceftriaxone and oral or intravenous lansoprazole increases the risk of ventricular arrhythmia and cardiac arrest in the real-world setting in Japan.
METHODS: The data analyzed were obtained from the JMDC hospital-based administrative claims database for the period April 2014 to August 2022. Patients who received a proton pump inhibitor (PPI) while receiving ceftriaxone or sulbactam/ampicillin were identified. The frequency of ventricular arrhythmia and cardiac arrest was analyzed according to whether oral or intravenous PPI was concomitant with ceftriaxone or sulbactam/ampicillin. Estimates of the incidence of ventricular arrhythmia and cardiac arrest were then compared among the groups, using the Fine-Gray competing risk regression model.
RESULTS: The results showed that the risk of ventricular arrhythmia and cardiac arrest was significantly higher with concomitant ceftriaxone and oral lansoprazole (hazard ratio 2.92, 95% confidence interval 1.99-4.29, P<0.01) or intravenous lansoprazole (hazard ratio 1.22, 95% confidence interval 1.02-1.46, P=0.03) than with concomitant sulbactam/ampicillin and oral or intravenous lansoprazole.
CONCLUSIONS: Oral and intravenous lansoprazole may increase the risk of ventricular arrhythmia and cardiac arrest in patients who are receiving ceftriaxone. - ArticleNaz S, Ali Z, Minhas A, Fatima A, Waseem S.Microb Pathog. 2023 Aug;181:106202.Cutaneous Leishmaniasis (CL) affects millions of people globally and has a significant impact on morbidity and mortality. Innate immune mediators are likely to influence the clinical phenotype of CL through primary responses that restrict or facilitate parasite spread. The aim of this preliminary study was to bring to attention the significance of microbiota in the development of CL and emphasized the necessity of including the role of microbiota in CL while promoting a One Health approach for managing diseases. To achieve this, we used 16S amplicon metagenome sequencing and QIIME2 pipeline to analyze the microbiome composition of CL-infected patients compared to non-infected, healthy subjects. 16S sequencing analysis showed serum microbiome was dominated by Firmicutes, Proteobacteria, Bacteroidota, and Actinobacteria. CL-infected individuals, Proteobacteria were the most prevalent (27.63 ± 9.79), with the relative abundance (10.73 ± 5.33) of Proteobacteria in control. Bacilli class was found to be the most prevalent in healthy controls (30.71 ± 8.44) while (20.57 ± 9.51) in CL-infected individuals. The class Alphaproteobacteria was found to be more in CL-infected individuals (5.47 ± 2.07) as compared to healthy controls (1.85 ± 0.39). The CL-infected individuals had a significantly lower relative abundance of the Clostridia class (p < 0.0001). An altered serum microbiome of CL infection and higher microbial abundance in the serum of healthy individuals was observed.
- ArticleGonzalez L, Domingo-Muelas A, Duart-Abadia P, Nuñez M, Mikolcevic P, Llonch E, Cubillos-Rojas M, Cánovas B, Forrow SMA, Morante-Redolat JM, Fariñas I, Nebreda AR.iScience. 2023 Mar 17;26(3):106202.In the adult mammalian brain, most neural stem cells (NSCs) are held in a reversible state of quiescence, which is essential to avoid NSC exhaustion and determine the appropriate neurogenesis rate. NSCs of the mouse adult subependymal niche provide neurons for olfactory circuits and can be found at different depths of quiescence, but very little is known on how their quiescence-to-activation transition is controlled. Here, we identify the atypical cyclin-dependent kinase (CDK) activator RingoA as a regulator of this process. We show that the expression of RingoA increases the levels of CDK activity and facilitates cell cycle entry of a subset of NSCs that divide slowly. Accordingly, RingoA-deficient mice exhibit reduced olfactory neurogenesis with an accumulation of quiescent NSCs. Our results indicate that RingoA plays an important role in setting the threshold of CDK activity required for adult NSCs to exit quiescence and may represent a dormancy regulator in adult mammalian tissues.
- ArticleGraff S, Bricmont N, Moermans C, Henket M, Paulus V, Guissard F, Louis R, Schleich F.Respir Med. 2020 12;175:106202.BACKGROUND AND OBJECTIVE: Airway remodeling, as many other factors, may lead to lung function decline and irreversible airflow obstruction (IRAO) in asthma. This study was undertaken in order to highlight predictors of incomplete reversibility of airflow obstruction in adult asthmatics to identify patients with poorer prognosis and improve their care, and decrease morbidity.
METHODS: A retrospective study was conducted in 973 asthmatics recruited from the University Asthma Clinic of Liege. Patients with IRAO (post-BD FEV1/FVC<0.7 & FEV1<80% predicted) were compared to patients with reversible airway obstruction (RAO) (post-BD FEV1/FVC≥0.7 & FEV1≥80% predicted). TGF-β was measured in sputum supernatant of 85 patients.
RESULTS: Seventeen percent of asthmatics presented with IRAO. These patients were significantly older, more smokers, with a lower proportion of female, a longer disease duration, were more poorly controlled with a lower quality of life. This sub-population of asthmatics also showed more often elevated blood and sputum eosinophils and neutrophils, and higher exacerbation and hospitalisation rates in the previous year. The multivariable analysis revealed male gender, longer disease duration, cigarette smoking, ACQ score, sputum eosinophils and neutrophils, ICS dose and OCS maintenance, BMI, and asthma onset as variables independently linked to IRAO. Total TGF-β levels appeared higher in patients with IRAO (n = 38) compared to patients with RAO (n = 47).
CONCLUSION: These data show that risk factors for IRAO are male gender, smoking, a longer disease duration, uncontrolled asthma, eosinophilic or neutrophilic airway inflammation, lower BMI, and later asthma onset. Moreover, TGF-β levels are higher in IRAO. - ArticleTalesh Jafadideh A, Mohammadzadeh Asl B.Comput Biol Med. 2022 11;150:106202.Autism spectrum disorder (ASD) is a heterogeneous disorder with a rapidly growing prevalence. In recent years, the dynamic functional connectivity (DFC) technique has been used to reveal the transient connectivity behavior of ASDs' brains by clustering connectivity matrices in different states. However, the states of DFC have not been yet studied from a topological point of view. In this paper, this study was performed using global metrics of the graph and persistent homology (PH) and resting-state functional magnetic resonance imaging (fMRI) data. The PH has been recently developed in topological data analysis and deals with persistent structures of data. The structural connectivity (SC) and static FC (SFC) were also studied to know which one of the SC, SFC, and DFC could provide more discriminative topological features when comparing ASDs with typical controls (TCs). Significant discriminative features were only found in states of DFC. Moreover, the best classification performance was offered by persistent homology-based metrics and in two out of four states. In these two states, some networks of ASDs compared to TCs were more segregated and isolated (showing the disruption of network integration in ASDs). The results of this study demonstrated that topological analysis of DFC states could offer discriminative features which were not discriminative in SFC and SC. Also, PH metrics can provide a promising perspective for studying ASD and finding candidate biomarkers.
- Articlede Melo Junior JO, Lodi Campos Melo MA, da Silva Lavradas LA, Ferreira Lopes PG, Luiz Ornelas II, de Barros PL, da Mata Pereira PJ, Niemeyer Filho P.Clin Neurol Neurosurg. 2020 10;197:106202.OBJECTIVE: Venous thromboembolism (VTE) is particularly prevalent in neurosurgical patients. A major dilemma arises when a patient needs to be treated with therapeutic anticoagulation during the early days after brain surgery due to the concern of intracranial hemorrhage (ICH). There is still a lack of studies regarding the optimal time to start therapeutic anticoagulation and risk assessment of ICH in this setting. This study aims to assess the risk of ICH for patients with venous thromboembolism treated with therapeutic anticoagulation started within the first 30 days after intracranial neurosurgical procedure.
PATIENTS AND METHODS: This study was an analytical observational research based on a retrospective record review of VTE patients submitted to therapeutic anticoagulation started within the first 30 days after intracranial neurosurgical procedure at Paulo Niemeyer State Brain Institute, from September 2013 to February 2020. Patients' clinical and surgical data, anticoagulation drug therapy, time interval between surgery and start of therapeutic anticoagulation, bleeding complications and hemorrhage-related deaths were some of variables evaluated. A p value < 0.05 was considered statistically significant.
RESULTS: A series of 53 consecutive patients and 54 intracranial neurosurgical procedures met the criteria. Twenty-nine (53.7 %) patients were treated with warfarin, 21 (38.9 %) with new oral anticoagulant (NOAC) and 4 (7.4 %) only with enoxaparin. VTE diagnosis between the postoperative days 0 and 4 was statistically associated with a delay in starting therapeutic anticoagulation of more than two days (p < 0.001). The frequency of bleeding complication was statistically significant higher in patients treated with warfarin (p = 0.03). Although with no statistical significance, there were a higher rate of ICH in patients receiving warfarin (13.8 % vs. 0% in NOAC group, p = 0.13). There was no statistical difference about ICH incidence between the postoperative intervals from 2nd to 7th, 8th to 14th, 15th to 21 st and 22th to 29th days (p = 0.35). Hemorrhage-related mortality rate was 3.7 %.
CONCLUSION: ICH was not statistically associated with the timing of therapeutic anticoagulation after brain surgery between the 2nd and 29th postoperative days, which may encourage the strategy of early treatment considering the life-threatening potential of VTE. However, the risk of ICH should not be ignored in the setting of warfarin use, which had a remarkable incidence of 13.8 %. Warfarin must be used cautiously, especially in high-grade gliomas. - ArticleThygesen SJ, Pliego-Zamora A, Stacey KJ.EMBO J. 2020 09 01;39(17):e106202.Shigella, a major cause of bacterial dysentery, knows when it is not wanted. To generate and maintain its niche within host cells, this unwelcome guest injects several dozen virulence factors via a type 3 secretion system (T3SS). In this issue, Ashida et al (2020) have elucidated the role of two such factors from Shigella flexneri-OspC1 and OspD3-that together counteract apoptotic and necroptotic death pathways in colonised epithelial cells. As a result, Shigella can replicate to high levels within the colonic epithelium, leading to the substantial epithelial damage in shigellosis and efficient bacterial release for faecal transmission.
- ArticleXiao Y, Adegoke M, Leung CS, Leung KW.Neural Netw. 2024 May;173:106202.The concept of randomized neural networks (RNNs), such as the random vector functional link network (RVFL) and extreme learning machine (ELM), is a widely accepted and efficient network method for constructing single-hidden layer feedforward networks (SLFNs). Due to its exceptional approximation capabilities, RNN is being extensively used in various fields. While the RNN concept has shown great promise, its performance can be unpredictable in imperfect conditions, such as weight noises and outliers. Thus, there is a need to develop more reliable and robust RNN algorithms. To address this issue, this paper proposes a new objective function that addresses the combined effect of weight noise and training data outliers for RVFL networks. Based on the half-quadratic optimization method, we then propose a novel algorithm, named noise-aware RNN (NARNN), to optimize the proposed objective function. The convergence of the NARNN is also theoretically validated. We also discuss the way to use the NARNN for ensemble deep RVFL (edRVFL) networks. Finally, we present an extension of the NARNN to concurrently address weight noise, stuck-at-fault, and outliers. The experimental results demonstrate that the proposed algorithm outperforms a number of state-of-the-art robust RNN algorithms.
- ArticleAurich C, Müller-Herbst S, Reineking W, Müller E, Wohlsein P, Gunreben B, Aurich J.Anim Reprod Sci. 2019 Dec;211:106202.Warmblood fragile foal syndrome (WFFS) is a monogenetic defect with autosomal recessive inheritance. The WFFS homozygosity is non-compatible with extra-uterine life. Although as many as 15% of Warmblood horses are WFFS carriers, there has been little veterinary focus on this condition. The aim of this study was to determine outcomes and symptoms of clinical signs and pathological abnormalities during pregnancies when there were WFFS homozygous foetuses. Diagnostic material of 15 abortion or stillbirth cases with suspected diagnosis of WFFS was available for this study. Additionally, there were examinations in 37 cases where there were no indications of WFFS when submitted for routine diagnostic procedures. Foals in all cases were genotyped and external morphological defects were recorded. Amongst the 15 cases in which WFSS was suspected, there were 14 homozygous foetuses with the WFFS allele (WFFS/WFFS). Three heterozygous WFFS foetuses (N/WFFS) were detected in the cases submitted for routine diagnostic procedures. Of the 14 WFFS homozygous foetuses, 11 of mares had a gestation length of at least 320 days. Nine foals were born alive but died within a short time. Skin defects were obvious in 12 WFFS homozygous foals, and there was abnormal flexibility in the digital joints, flexed forelegs and incomplete closure of the abdominal wall in five, four, and one of the foals, respectively. In conclusion, the predominant manifestation of WFFS are death during the latter stages of gestation or live births with foals being non-viable. Losses in Warmblood horse breeding caused by WFFS are greater than previously assumed.
