Abstract
Diarrhoea is prevalently widespread in developing countries and can lead to death. This
disease could be caused by a prerequisite attachment of Enterotoxigenic Escherichia coli
(ETEC) on human intestinal epithelial cells and followed by toxin production. Several
antibiotics have been developed to reduce diarrhoeal severity. However, the use of
antibiotics could also disrupt the balance of gut microbiota. This research found that
tempeh fermented with the addition of Lactobacillus plantarum culture could decrease the
adhesion of ETEC to the intestinal epithelial cells. This study measured the ability of L.
plantarum to produce exopolysaccharide (EPS) and examined the effect of L. plantarum
addition to tempeh, particularly its effect on anti-adhesion activity against ETEC. By
using yeast agglutination assay to observe anti-adhesion activity, the data showed that
soybean tempeh fermented with the addition of L. plantarum at OD600 of 0.5 had an
increase of anti-adhesion bioactivity against ETEC nearly three times compared to tempeh
without the addition of L. plantarum culture. Moreover, the exclusion test showed that
EPS from L. plantarum could act as a preventive agent against ETEC adhesion to
eukaryotic cells. Our finding indicated that the addition of lactic acid bacteria culture can
be considered to augment the anti-adhesion bioactivity in soybean tempeh against ETEC.

Abstract
The development of environment-friendly natural polymer gel-like dispersions in oil media, with functional properties, in terms of formulation design and synthesis protocol, is still a cutting-edge research area for many applications. The aim of this work was to study the manufacture of electrospun ethylcellulose (EC) nanofibrous webs and to examine their usage to thicken vegetable oils as an alternative approach. The role of concentration, molecular weight (Mw), and binary solvent systems on the electrospinnability of EC and subsequently on the rheological properties of EC nanofiber dispersions in castor oil was investigated. It was observed that, for each Mw, defect-free nanofibers were produced above a critical concentration, corresponding to about 2.5 the entanglement concentration (Ce). The average fiber diameter increased with both Mw and EC concentrations. Dielectric constant and dipole moment of binary solvent systems influenced the morphology of the EC nanofiber web. The morphology of the micro- and nanoarchitectures generated played a key role in the physical stabilization and rheological behavior of electrospun EC dispersions. The storage modulus (G') of EC dispersions was correlated with both the spinning solution concentration and average fiber diameter. Furthermore, electrospun EC nanofiber dispersions were compared with EC oleogels obtained by traditional thermogelation from thermorheological and tribological points of view. Overall, this work proposes an efficient and innovative approach to produce bio-based oleogel-like dispersions with great potential in different sectors such as pharmaceuticals, food, or lubricants.

Influence of surfactants on the electrospinnability of lignin-PVP solutions and subsequent oil structuring properties of nanofiber mats. Polym Bull (Berl) 2022.

Abstract
AbstractThis work focuses on the improvement of the electrospinnability of low-sulfonate lignin (LSL)/polyvinylpyrrolidone (PVP) solutions by the addition of surfactants (SDS, CTAB and Tween-20) as well as on the ability of resulting nanofibers to structure castor oil. Solutions with two LSL/PVP weight ratios (70:30 and 90:10) in DMF were prepared by adding variable surfactant concentrations (0–1 wt.%), and physicochemically characterized. Electrical conductivity, surface tension and rheological measurements were performed. Variations of these physicochemical properties were explained on the basis of surfactant-polymer interactions. The addition of surfactants to LSL/PVP solutions improves electrospinnability, producing more compact and uniform fiber mats in 70:30 LSL/PVP systems, generally reducing the average diameter of the nanofibers and the number of beads. In contrast, nanofiber mats were not obtained with 90:10 LSL/PVP solutions, but different nanostructures composed of particle clusters. Dispersions of nanofiber mats obtained by electrospinning from 70:30 LSL/PVP solutions in castor oil were able to generate physically stable strong oleogels. In general, linear viscoelastic functions of oleogels increased with surfactant concentration. In addition, these oleogels exhibited excellent lubrication performance in a tribological contact, with extremely low values of the friction coefficient and wear diameters, which may lead to potential applications as lubricants.

Abstract
PURPOSE Research suggests that ethnicity is a predictor of pain-related outcomes; however, studies comparing the differences in experimental pain sensitivity between Hispanics and non-Hispanic Whites (NHW) are scarce. This study investigated these differences between Hispanics and NHW from the U.S- Mexico border. METHODS Fifty-eight healthy subjects completed the survey packet, which included a demographic and a psychosocial factors questionnaire. Participants underwent quantitative sensory testing which included heat pain threshold, heat pain tolerance, Suprathreshold Heat Pain Response (SHPR), and Conditioned Pain Modulation (CPM). SHPR was induced by repeated thermal stimuli in both thenar eminences. CPM was assessed using SHPR as the experimental stimulus, and cold pressor task as the conditioning stimulus. RESULTS Analyses showed significant differences in experimental pain measures believed to be representative of facilitatory pain processing including SHPR, and heat pain threshold, where Hispanics reported significantly higher pain ratings than NHW. Hispanics also reported higher levels of ethnic identity and acculturation. However, these factors were not significantly associated with experimental pain sensitivity. CONCLUSION The experimental pain sensitivity and psychosocial factors included in this study differed by ethnic group, where Hispanics reported significantly higher pain ratings, when compared to NHW. However, ethnic identity and acculturation were not associated with these pain-related outcomes. Overall, enhanced understanding by clinicians of pain sensitivity and disparities in the pain experience between ethnic groups allows for increased cultural sensitivity and can be used to optimize pain treatment on an individual-by-individual basis.

Abstract
Purpose The purpose of this study was to examine the intermediary role of physical health quality of life and ability to participate social roles and activities in the relationship between pain intensity and mental health quality of life in veterans with mental illnesses. Methods This is a cross-sectional correlational design study. Our participants are 156 veterans with self-reported mental illness (Mage = 37.85; SDage = 10.74). Descriptive, correlation, and mediation analyses were conducted for the current study. Results Pain intensity was negatively correlated with physical health QOL, ability to participate in social roles and activities, and mental health QOL. Physical health QOL and ability to participate in social roles and activities were positively associated with mental health QOL, respectively. Physical health QOL was positively correlated with a ability to participate in social roles and activities. Study results indicate that the effect of pain intensity on mental health QOL can be explained by physical health QOL and ability to participate. Conclusions Specific recommendations for practitioners include implementing treatment goals that simultaneously focus on physical health and ability to participate in social roles and activities for clients who present with both physical pain and low mental health QOL.

Biopsychosocial Influences on Shoulder Pain: Analyzing the Temporal Ordering of Postoperative Recovery. THE JOURNAL OF PAIN 2019; 21:808-819.

Abstract
Shoulder surgery is a primary intervention for shoulder pain, yet many individuals experience persistent postoperative pain. Previously, we found individuals categorized as having a high-risk phenotype (comprised of COMT variation and pain catastrophizing) had approximately double the chance of not reaching a 12-month pain recovery criterion. As a means to better understand the development of persistent postoperative shoulder pain, this study advanced our previous work by examining temporal ordering of postoperative shoulder recovery based on potential mediating factors, and expansion of outcomes to include movement-evoked pain and shoulder active range of motion. Before surgery, individuals were categorized as either high-risk (high pain catastrophizing, COMT-genotype linked to low enzyme activity [n = 41]) or low-risk (low pain catastrophizing, COMT-genotype linked to normal enzyme activity [n = 107]). We then compared potential mediating variables at 3, 6, and 12 months postoperatively 1) endogenous pain modulation defined by a conditioned pain modulation paradigm; and 2) and emotion factors such as anxiety, fear of movement, and depressive symptoms. At 3 months, the high-risk subgroup had higher fear and movement-evoked pain, and causal mediation analysis confirmed the direct effect of risk subgroup on 12-month movement evoked pain. However, baseline to 12-month change in depressive symptoms were found to mediate 53% of the total effect of risk subgroup on 12-month movement-evoked pain. This study introduces potential temporal components and relationships to the development of persistent postoperative shoulder pain, which future studies will confirm and assess for potential therapeutic targets. PERSPECTIVE: This study expands upon postoperative shoulder recovery measures to include movement-evoked pain and depressive symptoms, and provides preliminary indication of temporal ordering to postoperative shoulder recovery for a preidentified high-risk subgroup. Future studies will distinguish temporal components of shoulder surgery that may optimize treatment targets of postoperative recovery.

Disturbed testicular expression of the estrogen-metabolizing enzymes CYP1A1 and COMT in infertile men with primary spermatogenic failure: possible negative implications on Sertoli cells. Andrology 2017; 5:486-494. [PMID: 28334509 DOI: 10.1111/andr.12346] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2016] [Revised: 12/27/2016] [Accepted: 01/29/2017] [Indexed: 01/21/2023]
Abstract
Estradiol (E2 ) is normally metabolized to hydroxyestradiols and methoxyestradiols by CYP1A1, CYP1B1 and COMT. However, an altered production of these metabolites by a disturbed expression of these enzymes is associated with reproductive and non-reproductive pathologies. In vitro studies suggest that increased hydroxyestradiols and methoxyestradiols intratesticular generation is related to male infertility, but no studies have explored whether infertile men have a disturbed testicular expression of the enzymes that generate these E2 metabolites. The aim of this study was to assess CYP1A1, CYP1B1 and COMT testicular expression at mRNA and protein level in men with spermatogenic impairment. Seventeen men with primary spermatogenic failure (13 with Sertoli cell-only syndrome and four with maturation arrest) and nine controls with normal spermatogenesis were subjected to testicular biopsy. mRNA was quantified using real-time RT-PCR and protein expression was evaluated using western blot and immunohistochemistry followed by integrated optic density analysis. Besides, the effects of hydroxyestradiols and methoxyestradiols on testosterone-induced transcriptional activity were evaluated in TM4 cells using a luciferase reporter assay system. Our results show that patients with Sertoli cell-only syndrome had significantly elevated COMT expression at the mRNA level, higher COMT immunoreactivity in their seminiferous tubules and increased protein expression of the soluble COMT isoform (S-COMT), whereas patients with maturation arrest had significantly elevated CYP1A1 mRNA levels and higher CYP1A1 immunoreactivity in interstitial space. Finally, 2-hydroxyestradiol decreased testosterone-induced transcriptional activity in Sertoli cells in vitro. In conclusion, male infertility is related to disturbed testicular expression of the enzymes responsible for producing hydroxyestradiols and/or methoxyestradiols. If these changes are related with increased intratesticular hydroxyestradiols and methoxyestradiols concentrations, they could elicit an impaired Sertoli cell function. Our results suggest CYP1A1 and COMT as new potential targets in treating male infertility.

Abstract
Tomato paste is used as an ingredient for the manufacture of tomato ketchup. This paper deals with the influence that some tomato paste processing variables (finisher screen opening and breaking temperature) and tomato variety exert on the linear viscoelastic properties of tomato ketchup. Two tomato varieties (H-282 and H-282F) were used. H-282 is a commercial variety whilst H-282F is a variety with a lower content in polygalacturonase (PG). Dynamic viscoelastic tests and particle size distribution measurements were carried out. Viscoelastic properties of tomato ketchup were mainly related to their mean volume diameter, tomato paste water-insoluble solids content (that depended on the tomato paste processing) and tomato variety.

Abstract
INTRODUCTION Cerebrospinal fluid (CSF) from amyotrophic lateral sclerosis (ALS) patients induces cytotoxic effects in in vitro cultured motor neurons. MATERIAL AND METHODS We selected CSF with previously reported cytotoxic effects from 32 ALS patients. Twenty-eight adult male rats were intracerebroventricularly implanted with osmotic mini-pumps and divided into 3 groups: 9 rats injected with CSF from non-ALS patients, 15 rats injected with cytotoxic ALS-CSF, and 4 rats injected with a physiological saline solution. CSF was intracerebroventricularly and continuously infused for periods of 20 or 43days after implantation. We conducted clinical assessments and electromyographic examinations, and histological analyses were conducted in rats euthanised 20, 45, and 82days after surgery. RESULTS Immunohistochemical studies revealed tissue damage with similar characteristics to those found in the sporadic forms of ALS, such as overexpression of cystatinC, transferrin, and TDP-43 protein in the cytoplasm. The earliest changes observed seemed to play a protective role due to the overexpression of peripherin, AKTpan, AKTphospho, and metallothioneins; this expression had diminished by the time we analysed rats euthanised on day 82, when an increase in apoptosis was observed. The first cellular changes identified were activated microglia followed by astrogliosis and overexpression of GFAP and S100B proteins. CONCLUSION Our data suggest that ALS could spread through CSF and that intracerebroventricular administration of cytotoxic ALS-CSF provokes changes similar to those found in sporadic forms of the disease.

Abstract
Background There is limited literature investigating preoperative physical therapy (pre-op PT) treatment on pain intensity and disability after musculoskeletal surgery. The purposes of the present cohort study were to describe patient characteristics for those who had and did not have pre-op PT treatment and determine whether pre-op PT influenced the length of postoperative physical therapy (post-op PT) treatment (number of sessions) and 3-month and 6-month postsurgical outcomes, such as pain intensity and disability. Patients and methods A total of 124 patients (mean age =43 years, 81 males) with shoulder pain were observed before and after shoulder arthroscopic surgery. Demographic data, medical history, and validated self-report questionnaires were collected preoperatively and at 3 months and 6 months after surgery. Analysis of variance models were performed to identify differences across measures for patients who had pre-op PT treatment and those who did not and to examine outcome differences at 3 months and 6 months. Alpha was set at the 0.05 level for statistical significance. Results Males had less participation in pre-op PT than females (P=0.01). In contrast, age, pain intensity, disability, and pain-associated psychological factors did not differ between pre-op PT treatment groups (P>0.05). Subacromial bursectomies were more commonly performed in patients having pre-op PT treatment (P<0.05). Pre-op PT treatment did not influence length of post-op PT treatment and did not affect 3-month and 6-month pain intensity and disability outcomes. Differences in distribution of pre-op PT for males and females and subacromial bursectomy did not influence 3-month or 6-month postsurgical outcomes. Conclusion Receiving pre-op PT treatment did not influence post-op PT treatment or pain and disability outcomes at 3 months and 6 months. This prospective cohort study provides no evidence of benefit for pre-op PT on post-op PT treatment or postsurgical outcomes. Females or patients receiving certain surgical procedures are more likely to undergo pre-op PT treatment. However, these differences did not influence postoperative outcomes in this cohort.

Abstract
Elevated intratesticular levels of hydroxyoestradiols and methoxyoestradiols, two classes of endogenous oestradiol metabolites, have been associated with male infertility. The aim of this study was to explore the effects of 2-hydroxyoestradiol (2OHE2 ), 4-hydroxyoestradiol (4OHE2 ), 2-methoxyoestradiol (2ME2 ) and 4-methoxyoestradiol (4ME2 ) on Sertoli cell viability. For this, TM4 cells were incubated with different concentrations of these metabolites for 24 h to then evaluate the viability and DNA integrity by MTS and TUNEL assay respectively. The participation of classical oestrogen receptors and the involvement of oxidative stress and apoptotic mechanisms were also evaluated co-incubating TM4 cells with these estradiol metabolites and with the drugs ICI182780, N-acetylcysteine and Z-VAD-FMK respectively. Only high concentrations of 2OHE2 and 2ME2 decreased cell viability inducing DNA fragmentation. In addition, ICI182780 did not block the effect of 2OHE2 and 2ME2 , while N-Acetylcysteine and Z-VAD-FMK only blocked the effect of 2OHE2 . Moreover, 2OHE2 but not 2ME2 induced PARP and caspase-3 cleavage. Finally, lower 2OHE2 and 2ME2 concentrations (0.01-0.1-1.0 μmol l-1 ) decreased Sertoli cell viability 48 h post-treatment. Our results support the hypothesis that elevated intratesticular 2OHE2 or 2ME2 concentrations could be related to male infertility since 2OHE2 by apoptosis and 2ME2 by undetermined mechanisms induce DNA fragmentation in Sertoli cells.

[PMID: 26376336 DOI: 10.1016/j.pmrj.2015.09.004] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2015] [Revised: 09/01/2015] [Accepted: 09/03/2015] [Indexed: 01/08/2023]
Abstract
BACKGROUND Shoulder pain and surgery are common among older adults. However, the extent to which older age affects recovery after shoulder surgery is not well understood. OBJECTIVE To assess influence of older age on postoperative recovery factors 3 and 6 months after shoulder arthroscopy. DESIGN Prospective cohort study. SETTING University-affiliated outpatient orthopedic surgical center. PATIENTS A convenience sample of 139 persons between 20 and 79 years of age who experienced shoulder pain, had musculoskeletal dysfunction based on imaging and physician assessment, and were scheduled for an arthroscopic shoulder procedure. MAIN OUTCOME MEASURES Postoperative outcomes were compared among younger, middle-aged, and older adults before surgery and at 3 and 6 months after surgery using analysis of variance modeling. Movement-evoked pain and an experimental laboratory correlate of pain processing were assessed at each time point. The influence of older age on 3- and 6-month pain outcomes were determined via multivariate regression analyses after accounting for preoperative, intraoperative, and postoperative prognostic factors. RESULTS Older adults had higher movement-evoked pain intensity (F2,108 = 5.18, P = .007) and experimental pain response (F2,111 = 7.24, P = .001) at 3 months compared with young and middle-aged adults. After controlling for key prognostic factors, older age remained a positive predictor of 3-month movement-evoked pain (R(2) = 0.05; standardized [St.] β = 0.263, P = .031) and experimental pain response (R(2) = 0.07; St. β = 0.295, P = .014). Further, older age remained a positive predictor of movement-evoked pain at 6 months (R(2) = 0.04; St. β = 0.231, P = .004), despite no age group differences in outcome. Older age was found to be the strongest predictor of 3- and 6-month movement-evoked pain. CONCLUSION Older adults may experience more pain related to movement, as well as endogenous pain excitation, in the first few months after shoulder arthroscopy. Future age-related research should consider use of movement-evoked pain intensity and experimental pain response as pain outcomes, as well as the utility of such measures in clinical care.

Abstract
BACKGROUND Measures of central pain processing like conditioned pain modulation and suprathreshold heat pain response (SHPR) have been described to assess different components of central pain modulatory mechanisms. Central pain processing potentially plays a role in the development of postsurgical pain, however, the role of conditioned pain modulation and SHPR in explaining postoperative clinical pain and disability is still unclear. METHODS Seventy-eight patients with clinical shoulder pain were included in this study. Patients were examined before shoulder surgery, at 3 months, and 6 months after surgery. The primary outcome measures were pain intensity and upper extremity disability. RESULTS Analyses revealed that the change score (baseline- 3 mo) of fifth pain rating of SHPR accounted for a significant amount of variance in 6-month postsurgical clinical pain intensity and disability after age, sex, preoperative pain intensity, and relevant psychological factors were considered. CONCLUSIONS The present study suggests that baseline measures of central pain processing were not predictive of 6-month postoperative pain outcome. Instead, the 3-month change in SHPR might be a relevant factor in the transition to an elevated 6-month postoperative pain and disability outcomes. In patients with shoulder pain, the 3-month change in a measure of central pain processing might be a relevant factor in the transition to elevated 6-month postoperative pain and disability scores.

Abstract
INTRODUCTION Mild head trauma is a frequent complaint in Pediatric Emergency Departments. Several guidelines have been published in the last few years. However, significant variability can be appreciated in terms of the demand for image tests. The aim of this study is to determine the level of compliance with PECARN and AEP guidelines in the management of patients younger than 24 months old in four different hospitals. PATIENTS AND METHODS A multicenter retrospective study was conducted on patients presenting with mild head trauma between October 1st, 2011 and March 31st, 2013 in the Emergency Departments of four hospitals. RESULTS In the analysis of the results obtained, only one of the four hospitals complied with the AEP guidelines in more than 50% of the patients. The other three hospitals had a level of compliance lower than 50%. Management was more suitable according to PECARN guidelines, with 3 of the 4 hospitals having a level of compliance greater than 50%. However, the best compliance achieved by a hospital was only of 70%. CONCLUSIONS The study shows that the level of compliance with guidelines for management of mild head trauma in patients younger than 24 months old is low.

Abstract
OBJECTIVE The aims of this study were to (1) examine the pattern of experimental pain responses in the affected and nonaffected extremities in patients with shoulder pain and (2) explore the intraindividual association between sensitization states derived from experimental pain testing. METHODS Experimental pain responses from 58 patients with shoulder pain (17 women, aged 18 to 52 y) were compared with those from 56 age-matched and sex-matched pain-free volunteers (16 women, aged 21 to 58 y). Experimental pain responses included pressure pain threshold (PPT), thermal pain threshold and tolerance, and suprathreshold heat pain response. Comparisons were made between the affected and nonaffected extremities of clinical participants and the average response of extremities in control participants. Peripheral and central sensitization indexes were computed for clinical participants using standardized scores and percentile cutoffs on the basis of the data from the control sample. Experimental pain responses in clinical participants observed beyond the 25th and 75th percentile of control sample responses were used for investigation of intraindividual association of sensitization states. RESULTS PPT at the acromion and masseter on the affected side of clinical participants were diminished compared with that on their nonaffected side (P<0.015). Bilateral sensitivity in clinical participants was noted for PPT at the acromion and suprathreshold heat pain response (P<0.015). Peripheral and central sensitization indexes demonstrated that individuals with shoulder pain present with variable patterns of peripheral and central sensitization. CONCLUSIONS Collectively, experimental pain responses supported peripheral and central sensitization in response to pressure and thermal stimuli. No clear association was made between individuals exhibiting peripheral or central sensitization, thus suggesting heterogeneity in pain processing in this clinical population.

Abstract
OBJECTIVES To investigate neonatal morbidity in fetuses with severe congenital diaphragmatic hernia (CDH) treated with fetoscopic endoluminal tracheal occlusion (FETO) and compare it with historical controls with less severe forms of CDH that were managed expectantly. METHODS This was a prospective, multicenter study on neonatal outcomes and prenatal predictors in 90 FETO survivors (78 left-sided, 12 right) and 41 controls from the antenatal CDH registry with either severe or moderate hypoplasia who were managed expectantly. We also investigated early neonatal morbidity indicators, including the need for patch repair, duration of mechanical ventilation and supplemental oxygen, age at full enteral feeding and incidence of pulmonary hypertension. RESULTS Gestational age at delivery was predictive of duration of assisted ventilation (P = 0.046), days on supplemental oxygen (P = 0.019) and age at full enteral feeding (P = 0.020). When delivery took place after 34 weeks' gestation, neonatal morbidity of FETO cases was comparable with that of expectantly managed cases with moderate hypoplasia. CONCLUSIONS Fetal intervention for severe CDH is associated with neonatal morbidity that is comparable with that of an expectantly managed group with less severe disease.
