Abdominal Remodeling in Postpartum Women by Using a High-intensity Focused Electromagnetic (HIFEM) Procedure: An Investigational Magnetic Resonance Imaging (MRI) Pilot Study.

Objective: High-intensity focused electromagnetic (HIFEM) technology offers an alternative to surgical procedures in terms of correction of altered body shape. In this pilot study, we investigated whether HIFEM technology can positively affect abdominal appearance in postpartum women. Methods: Ten women (3-36 months postpartum; average age: 37.7 years) received four 30-minute abdominal HIFEM treatments. Magnetic resonance imaging (MRI) examination of abdominal fat thickness, rectus abdominis thickness, and the width of abdominal separation was performed and evaluated at baseline, one month, three months, and six months post-treatment. Additionally, weight was recorded, standardized photographs were taken, and patient comfort levels with the procedures were assessed, using a 7-point scale, at these same time points. The paired t-test was used to statistically analyze the mean differences between the baseline and post-treatment data. Results: Results obtained from MRI images showed an average abdominal fat reduction of 17.0 percent at the one-month follow-up visit, while at the three-month follow-up, it was 20.2 percent. The average muscle thickness increase at the one-month follow-up was 20.5 percent, and at the three-month follow-up, it was 21.3 percent. The distance between the rectus abdominis muscles was reduced by 16.7 percent at the first follow-up visit and by 22.7 percent at three-month follow-up visit. The nine subjects who attended the six-month visit showed, on average, a 17.6-percent fat reduction, 21.7-percent increase in muscle, and a 23.2-percent reduction of abdominal separation. Weight did not change significantly. Conclusion: HIFEM treatments appeared to reduce the fat layer and width of abdominal separation, while increasing the thickness of abdominal muscle thickness in postpartum women. The observed results at one month post-procedure were improved at three months post-procedure and remained stable at the six-month follow-up visit. Future studies that include a control or sham group are needed to identify and reduce the risk of bias.
A Nurse-Led Initiative to Improve Implementation of HIV Preconception Care Services.

ABSTRACT United States guidelines recommend preconception care (PCC) as an integral part of primary care to improve maternal and fetal/newborn outcomes and promote planned pregnancies. Persons living with HIV have additional, specialized needs for PCC. However, PCC is not reliably integrated in HIV care, and few studies have examined strategies to improve the provision of PCC services. We describe a successful, nurse-led initiative that incorporated collaborative strategic planning in conjunction with staff education and continuous quality improvement to strengthen implementation of PCC in a small urban HIV care clinic. Key features of this project included consensus building, training, and action planning with clinic staff; addressing clinic-specific barriers; and providing ongoing support/technical assistance. Continuous quality improvement reviews at 12, 18, and 36 months demonstrated improved and sustained implementation of PCC services for women and men. Our experiences serve as a model for HIV primary care clinics working to advance implementation of PCC services.
Dopamine D1 + D3 receptor density may correlate with parkinson disease clinical features

Dopamine D2‐like receptors – mainly dopamine D2 receptors (D2R) and dopamine D3 receptors (D3R) – are believed to be greatly involved in the pathology of Parkinson disease (PD) progression. However, these receptors have not been precisely examined in PD patients. Our aim was to quantitatively calculate the exact densities of dopamine D1 receptors (D1R), D2R, and D3R in control, Alzheimer disease (AD), and Lewy body disease (LBD) patients (including PD, Dementia with Lewy bodies, and Parkinson disease dementia); and analyze the relationship between dopamine receptors and clinical PD manifestations.
Dermal Fungicide Exposure at Realistic Field Rates Induces Lethal and Sublethal Effects on Juvenile European Common Frogs (Rana temporaria)

Viticulture is one of the most pesticide‐intensive agricultures in Europe, leading to a spatiotemporal overlap of amphibian migration and pesticide applications. Because postmetamorphic, terrestrial amphibian stages are mostly neglected in ecotoxicological studies, we investigated acute effects of viticultural fungicides on juvenile common frogs (Rana temporaria). Tadpoles from an uncontaminated pond were placed in enclosures in 8 ponds with an increasing degree of pesticide contamination in southwest Germany to represent different aquatic exposure backgrounds. After metamorphosis, juveniles were exposed to soil contaminated with 50% of the recommended field rates of the fungicides Folpan® 80 water dispersible granule (WDG) and Folpan® 500 suspension concentrate with the same amount of folpet as active ingredient and differing additives. After 48 h, effects on the survival, body mass, and behavior were investigated. No effect of the aquatic exposure background on terrestrial sensitivity could be detected. Acute terrestrial exposure led to mean mortality rates of 14% (13–17%, suspension concentrate) and 60% (17–100%, WDG) and resulted in adverse effects on locomotor activity as well as feeding behavior. Moreover, the results suggest that the toxicity of the 2 tested folpet formulations depends on their additives. Because the identified effects may result in severe impairments and thus in declines of amphibian populations, a more protective risk assessment of pesticides is needed for postmetamorphic amphibians to ensure proper conservation of amphibian populations.

Calcium Increase and Substance P Release Induced by the Neurotoxin Brevetoxin-1 in Sensory Neurons: Involvement of PAR2 Activation through Both Cathepsin S and Canonical Signaling

Red tides involving Karenia brevis expose humans to brevetoxins (PbTxs). Oral exposition triggers neurotoxic shellfish poisoning, whereas inhalation induces a respiratory syndrome and sensory disturbances. No curative treatment is available and the pathophysiology is not fully elucidated. Protease-activated receptor 2 (PAR2), cathepsin S (Cat-S) and substance P (SP) release are crucial mediators of the sensory effects of ciguatoxins (CTXs) which are PbTx analogs. This work explored the role of PAR2 and Cat-S in PbTx-1-induced sensory effects and deciphered the signaling pathway involved. We performed calcium imaging, PAR2 immunolocalization and SP release experiments in monocultured sensory neurons or co-cultured with keratinocytes treated with PbTx-1 or P-CTX-2. We demonstrated that PbTx-1-induced calcium increase and SP release involved Cat-S, PAR2 and transient receptor potential vanilloid 4 (TRPV4). The PbTx-1-induced signaling pathway included protein kinase A (PKA) and TRPV4, which are compatible with the PAR2 biased signaling induced by Cat-S. Internalization of PAR2 and protein kinase C (PKC), inositol triphosphate receptor and TRPV4 activation evoked by PbTx-1 are compatible with the PAR2 canonical signaling. Our results suggest that PbTx-1-induced sensory disturbances involve the PAR2-TRPV4 pathway. We identified PAR2, Cat-S, PKA, and PKC that are involved in TRPV4 sensitization induced by PbTx-1 in sensory neurons.

CASE PRESENTATION An autopsy performed on a 59-year-old man whowas found deceased on the floor of his closed garage, apparently after leaving his vehicle running, revealed a carbon monoxide concentration of 68%, severe multifocal coronary artery atherosclerosis, with sites of 75% to 90% stenosis identified in all 3 major epicardial coronary arteries, and mild cardiomegaly, with a heart weight of
Assessment of transcriptional importance of cell line-specific features based on GTRD and FANTOM5 data

Creating a complete picture of the regulation of transcription seems to be an urgent task of modern biology. Regulation of transcription is a complex process carried out by transcription factors (TFs) and auxiliary proteins. Over the past decade, ChIP-Seq has become the most common experimental technology studying genome-wide interactions between TFs and DNA. We assessed the transcriptional significance of cell line-specific features using regression analysis of ChIP-Seq datasets from the GTRD database and transcriptional start site (TSS) activities from the FANTOM5 expression atlas. For this purpose, we initially generated a large number of features that were defined as the presence or absence of TFs in different promoter regions around TSSs. Using feature selection and regression analysis, we identified sets of the most important TFs that affect expression activity of TSSs in human cell lines such as HepG2, K562 and HEK293. We demonstrated that some TFs can be classified as repressors and activators depending on their location relative to TSS.
The diversity of Shine-Dalgarno sequences sheds light on the evolution of translation initiation

ABSTRACT Shine-Dalgarno (SD) sequences, the core element of prokaryotic ribosome-binding sites, facilitate mRNA translation by base-pair interaction with the anti-SD (aSD) sequence of 16S rRNA. In contrast to this paradigm, an inspection of thousands of prokaryotic species unravels tremendous SD sequence diversity both within and between genomes, whereas aSD sequences remain largely static. The pattern has led many to suggest unidentified mechanisms for translation initiation. Here we review known translation-initiation pathways in prokaryotes. Moreover, we seek to understand the cause and consequence of SD diversity through surveying recent advances in biochemistry, genomics, and high-throughput genetics. These findings collectively show: (1) SD:aSD base pairing is beneficial but nonessential to translation initiation. (2) The 5ʹ untranslated region of mRNA evolves dynamically and correlates with organismal phylogeny and ecological niches. (3) Ribosomes have evolved distinct usage of translation-initiation pathways in different species. We propose a model portraying the SD diversity shaped by optimization of gene expression, adaptation to environments and growth demands, and the species-specific prerequisite of ribosomes to initiate translation. The model highlights the coevolution of ribosomes and mRNA features, leading to functional customization of the translation apparatus in each organism.
Chemical Speciation and Fractionation in Soil and Sediment Heavy Metal Analysis: A Review

Abstract Today it is generally recognized that the particular behaviour of trace metals in the environment is determined by their specific physicochemical forms rather than by their total concentration. Several chemical speciation and fractionation methods for heavy metal analysis in soils and sediments have been and are still being developed and applied. They primarily are intended to understand the particular environmental behaviour of metals, present in a variety of forms and in a variety of matrices. Analytical developments, modifications of existing methods, and recent new approaches are reviewed and discussed. Techniques used include chemical extractions, ion-exchange/gel chromatography, filtration, centrifugation and sieving, selective solvent extraction. Moreover, the application of these various techniques in different research fields over the last years is explored. The value and the limitations of speciation and fractionation techniques applied in specific experimental work is outlined. It is d.
Effects of Sociality Level on Companion Dog Training through Food Reinforcement

Simple Summary This test evaluates how your dog reacts to strangers’ behavior. Dogs with high sociality interact positively with strangers, such as physical contact or close proximity to strangers. On the other hand, dogs with low social levels may exhibit fear and fear-related behaviors or may show aggressiveness to relieve them. Highly social dogs tend to keep their eyes on their owners longer and are more likely to interact with humans. This study showed that the results of social training of dogs through food enrichment were much more effective in both the high sociality and low sociality groups. In particular, the high sociality group showed a much higher increase in social behavior than the low sociality group. This suggests that sociality is highly related even in the process of communication and training between dogs and humans. It also shows that it can be reinforced more effectively in dog-human interactions. Abstract The purpose of this study was to investigate the effect of sociality level in dogs using food reinforcement. The companion dogs living mostly inside (IS) and those living mostly outside (OS) groups were further classified into high sociality (HS) and low sociality (LS) groups using a social test. The data were analyzed by observing videos of the dogs and recording nine categories of sociality. Passive; activity; and communication tasks were measured in terms of the time the dog first contacted the trainer; the time it took for the dog to approach within 1 m of the trainer, and the time the dog remained in contact. The IS and OS groups showed no significant differences in any category; except for close to trainer within 1 m of the active phase. However, in a comparison between the overall HS and LS groups; significant positive changes were observed in all items except for the first contact time to the trainer of the passive and active phase. This is an important result of the sociality level; as positive results can be predicted not only in a dog’s ability to adapt to the environment but also in the communication and training exchanges between dogs and humans
Platelet rich plasma in oral and maxillofacial surgery from the perspective of composition

Abstract The application of platelet-rich plasma (PRP) in oral and maxillofacial surgery has been thoroughly studied in the last two decades. Currently, different types of PRP are applied in the clinical practice, being the presence or absence of leukocytes one of the classification criteria. However, there is poor evidence assessing the influence of the PRP composition in their efficacy. In this context, the aim of this narrative review is to compile the existing evidence covering the efficacy of PRP in oral and maxillofacial surgery, starting from a systematic literature search and to qualitatively describe the efficacy outcomes from the composition perspective. According to the results of this review, the application of PRP in oral and maxillofacial surgery is a potential strategy to improve soft- and hard-tissue regeneration, observing differences in the efficacy of PRP depending on its composition and the studied application. P-PRP (the absence of leukocytes) has been more consistent in achieving beneficial effects in alveolar ridge preservation, management of post-extraction complications, bone augmentation and temporomandibular joint disorders. For that, the composition and methodology used to prepare the PRP should be a critical point when evaluating the efficacy of PRP.
The importance of manual white blood cell differential counts and platelet estimates in elephant hematology: blood film review is essential

Abstract Unique features of elephant hematology are known challenges in analytical methodology like two types of monocytes typical for members of the Order Afrotheria and platelet counts of the comparatively small elephant platelet. To investigate WBC differential and platelet data generated by an impedance-based hematology analyzer without availability of validated species-specific software for recognition of elephant WBCs and platelets, compared to manual blood film review. Blood samples preserved in ethylenediaminetetraacetic acid (EDTA) of 50 elephants (n = 35 Elephas maximus and n = 15 Loxodonta africana) were used. A Mann-Whitney test for independent samples was used to compare parameters between methods and agreement was tested using Bland-Altman bias plots. All hematological variables, including absolute numbers of heterophils, lymphocytes, monocytes, eosinophils, basophils, and platelets, were significantly different (p < 0.0001) between both methods of analysis, and there was no agreement using Bland-Altman bias plots. Manual review consistently produced higher heterophil and monocyte counts as well as platelet estimates, while the automated analyzer produced higher lymphocyte, eosinophil, and basophil counts. The hematology analyzer did not properly differentiate elephant lymphocytes and monocytes, and did not accurately count elephant platelets. These findings emphasize the importance of manual blood film review as part of elephant complete blood counts in both clinical and research settings and as a basis for the development of hematological reference intervals.
Suppression of Pax3–MITF-M Axis Protects from UVB-Induced Skin Pigmentation by Tetrahydroquinoline Carboxamide

Paired box gene 3 (Pax3) and cAMP responsive element-binding protein (CREB) directly interact with the cis-acting elements on the promoter of microphthalmia-associated transcription factor isoform M (MITF-M) for transcriptional activation in the melanogenic process. Tyrosinase (Tyro) is a target gene of MITF-M, and functions as a key enzyme in melanin biosynthesis. Tetrahydroquinoline carboxamide (THQC) was previously screened as an antimelanogenic candidate. In the current study, we evaluated the antimelanogenic activity of THQC in vivo and elucidated a possible mechanism. Topical treatment with THQC mitigated ultraviolet B (UVB)-induced skin pigmentation in guinea pig with decreased messenger RNA (mRNA) and protein levels of melanogenic genes such as MITF-M and Tyro. Moreover, THQC inhibited cAMP-induced melanin production in α-melanocyte-stimulating hormone (α-MSH)- or histamine-activated B16-F0 cells, in which it suppressed the expression of the MITF-M gene at the promoter level. As a mechanism, THQC normalized the protein levels of Pax3, a transcriptional activator of the MITF-M gene, in UVB-exposed and pigmented skin, as well as in α-MSH-activated B16-F0 culture. However, THQC did not affect UVB- or α-MSH-induced phosphorylation (activation) of CREB. The results suggest that suppression of the Pax3–MITF-M axis might be a potential strategy in the treatment of skin pigmentary disorders that are at high risk under UVB radiation.
Trials in Sleep Apnea and Stroke

Few randomized controlled trials have evaluated the effectiveness of continuous positive airway pressure (CPAP) in reducing recurrent vascular events and mortality in poststroke obstructive sleep apnea (OSA). To date, results have been mixed, most studies were underpowered and definitive conclusions are not available. Using lessons learned from prior negative trials in stroke, we reappraise prior randomized controlled trials that examined the use of CPAP in treating poststroke OSA and propose the following considerations: (1) Intervention-based changes, such as ensuring that patients are using CPAP for at least 4 hours per night (eg, through use of improvements in CPAP technology that make it easier for patients to use), as well as considering alternative treatment strategies for poststroke OSA; (2) Population-based changes (ie, including stroke patients with severe and symptomatic OSA and CPAP noncompliers); and (3) Changes to timing of intervention and follow-up (ie, early initiation of CPAP therapy within the first 48 hours of stroke and long-term follow-up calculated in accordance with sample size to ensure adequate power). Given the burden of vascular morbidity and mortality in stroke patients with OSA, there is a strong need to learn from past negative trials and explore innovative stroke prevention strategies to improve stroke-free survival.
Contribution of retrotrapezoid nucleus neurons to CO2‐amplified cardiorespiratory activity in spontaneously hypertensive rats

This study demonstrates that both CO2‐induced respiratory and cardiovascular responses are augmented in spontaneously hypertensive rats (SHRs). Genetic ablation of the retrotrapezoid nucleus (RTN) neurons depresses enhanced hypercapnic ventilatory response and eliminates CO2‐stimulated increase in arterial pressure and heart rate in SHRs. SHRs have a high protein level of pH‐sensitive channels in the RTN, including the TASK‐2 channel, Kv12.1 channel and acid‐sensing ion channel 3. The inhibition of putative TASK‐2 channel activity by clofilium diminishes amplified hypercapnic ventilatory and cardiovascular responses, and reduces the number of CO2‐activated RTN neurons in SHRs. These results indicate that RTN neurons contribute to enhanced CO2‐stimulated respiratory and cardiovascular responses in SHRs.
Serum IgG2 antibody multi-composition in systemic lupus erythematosus and in lupus nephritis (Part 2): prospective study

Abstract Objectives Circulating anti-ENO1 and anti-H2A IgG2 have been identified as specific signatures of LN in a cross-over approach. We sought to show whether the same antibodies identify selected population of patients with LN with potentially different clinical outcomes. Methods Here we report the prospective analysis over 36 months of circulating IgG2 levels in patients with newly diagnosed LN (n=91) and SLE (n=31) and in other patients with SLE recruited within 2 years from diagnosis (n=99). Anti-podocyte (ENO1), anti-nucleosome (DNA, histone 2 A, histone 3) and anti-circulating proteins (C1q, AnnexinA1-ANXA1) IgG2 antibodies were determined by home-made techniques. Results LN patients were the main focus of the study. Anti-ENO1, anti-H2A and anti-ANXA1 IgG2 decreased in parallel to proteinuria and normalized within 12 months in the majority of patients while anti-dsDNA IgG2 remained high over the 36 months. Anti-ENO1 and anti-H2A had the highest association with proteinuria (Heat Map) and identified the highest number of patients with high proteinuria (68% and 71% respectively) and/or with reduced estimated glomerula filtration rate (eGFR) (58% for both antibodies) compared with 23% and 17% of anti-dsDNA (agreement analysis). Anti-ENO1 positive LN patients had higher proteinuria than negative patients at T0 and presented the maximal decrement within 12 months. Conclusions Anti-ENO1, anti-H2A and anti-ANXA1 antibodies were associated with high proteinuria in LN patients and Anti-ENO1 also presented the maximal reduction within 12 months that paralleled the decrease of proteinuria. Anti-dsDNA were not associated with renal outcome parameters. New IgG2 antibody signatures should be utilized as tracers of personalized therapies in LN.
