Polymorphisms and haplotypes of TOLLIP and MUC5B are associated with susceptibility and survival in patients with fibrotic hypersensitivity pneumonitis. Pulmonology 2024:S2531-0437(24)00007-2. [PMID: 38309995 DOI: 10.1016/j.pulmoe.2024.01.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2023] [Revised: 12/27/2023] [Accepted: 01/04/2024] [Indexed: 02/05/2024] Open
Abstract
INTRODUCTION AND OBJECTIVES Hypersensitivity pneumonitis (HP) is an interstitial lung disease with diverse clinical features that can present a fibrotic phenotype similar to idiopathic pulmonary fibrosis (IPF) in genetically predisposed individuals. While several single nucleotide polymorphisms (SNPs) have been associated with IPF, the genetic factors contributing to fibrotic HP (fHP) remain poorly understood. This study investigated the association of MUC5B and TOLLIP variants with susceptibility, clinical presentation and survival in Portuguese patients with fHP. MATERIAL AND METHODS A case-control study was undertaken with 97 fHP patients and 112 controls. Six SNPs residing in the MUC5B and TOLLIP genes and their haplotypes were analyzed. Associations with risk, survival, and clinical, radiographic, and pathological features of fHP were probed through comparisons among patients and controls. RESULTS MUC5B rs35705950 and three neighboring TOLLIP variants (rs3750920, rs111521887, and rs5743894) were associated with increased susceptibility to fHP. Minor allele frequencies were greater among fHP patients than in controls (40.7% vs 12.1%, P<0.0001; 52.6% vs 40.2%, P = 0.011; 22.7% vs 13.4%, P = 0.013; and 23.2% vs 12.9%, P = 0.006, respectively). Haplotypes formed by these variants were also linked to fHP susceptibility. Moreover, carriers of a specific haplotype (G-T-G-C) had a significant decrease in survival (adjusted hazard ratio 6.92, 95% CI 1.73-27.64, P = 0.006). Additional associations were found between TOLLIP rs111521887 and rs5743894 variants and decreased lung function at baseline, and the MUC5B SNP and radiographic features, further highlighting the influence of genetic factors in fHP. CONCLUSION These findings suggest that TOLLIP and MUC5B variants and haplotypes may serve as valuable tools for risk assessment and prognosis in fibrotic hypersensitivity pneumonitis, potentially contributing to its patient stratification, and offer insights into the genetic factors influencing the clinical course of the condition.

Predictors of immune-related adverse events and outcomes in patients with NSCLC treated with immune-checkpoint inhibitors. Pulmonology 2022:S2531-0437(22)00076-9. [PMID: 35414494 DOI: 10.1016/j.pulmoe.2022.03.003] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2021] [Revised: 03/14/2022] [Accepted: 03/14/2022] [Indexed: 10/18/2022] Open
Abstract
OBJECTIVE To identify predictors of immune-related adverse events (IRAEs) in patients with non-small cell lung cancer (NSCLC) treated with immune checkpoint inhibitors (ICIs). Assess associations between outcomes and the development of IRAEs. METHODS Retrospective analysis of patients with NSCLC treated with ICIs between 2016 and 2020 in the Pulmonology Department of our hospital. Patients with and without IRAEs were compared. A logistic regression analysis was performed to determine predictors of IRAEs. Progression-free survival (PFS) and overall survival (OS) curves were calculated using the Kaplan-Meier method, and the long-rank test was used to assess survival differences between groups. Univariate and multivariate Cox proportional-hazards regression models were used to identify factors associated with PFS and OS. The value considered statistically significant was p≤0.05. RESULTS A total of 184 patients (77.7% men, mean age 66.9±9.5 years) treated with ICIs were analyzed. During follow-up, 49 (26.6%) patients developed IRAEs and 149 (81.0%) died. According to the multivariate logistic regression analysis, treatment with statins (OR:3.15; p = 0.007), previous systemic corticosteroid therapy (OR:3.99; p = 0.001), disease controlled as response to ICI (OR:5.93; p < 0.001) and higher hemoglobin values (OR:1.28; p = 0.040) were independent predictors for the development of IRAEs. Patients who developed IRAEs had significantly longer medians of PFS (41.0 vs 9.0 weeks, p < 0.001) and OS (89.0 vs 28.0 weeks; p < 0.001). CONCLUSIONS Patients treated with statins, pre-ICI systemic corticosteroids, higher baseline hemoglobin value and controlled disease as initial response to ICI had a higher risk of developing IRAEs. The development of IRAEs was associated with better outcomes.

Recruitment of lysosomal cathepsins B, L and D as digestive enzymes in Coleoptera. INSECT MOLECULAR BIOLOGY 2022; 31:225-240. [PMID: 34918424 DOI: 10.1111/imb.12753] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/08/2021] [Revised: 11/18/2021] [Accepted: 12/13/2021] [Indexed: 06/14/2023]
Abstract
The recruitment of the lysosomal cathepsins B (CAB), L (CAL) and D (CAD) as luminal digestive enzymes was investigated in 3 species of beetles. Gene expression was determined by RNA-seq in different regions of the midgut and in the carcasses from the transcriptomes of Dermestes maculatus, Tenebrio molitor and Zabrotes subfasciatus. These data together with phylogenetic analyses, allowed us to identify the sequences of the gene coding for digestive and lysosomal CABs, CADs and CALs in T. molitor and Z. subfasciatus and observe the absence of digestive cathepsins in D. maculatus. Comparisons of structures based on the overall similarity of modelled structures were performed and subsite residues in the lysosomal and digestive CALs were identified by molecular docking. The data showed that S2 subsites are very variable, probably as an adaption to a luminal digestive role. The survey of sequences of the gene coding for cathepsins in the genomes of 13 beetle species from different phylogenetic groups showed that expansion of CAL and CAB genes occurred only in the Cucujiformia clade. Several digestive CABs have a reduced occluding loop, probably to act as digestive enzymes. Pollen-feeding was proposed to be the selective pressure to recruit cathepsins as digestive enzymes in Cucujiformia beetles.

Abstract
INTRODUCTION The evolution of patients with obstructive sleep apnea (OSA) non-eligible for PAP-therapy at diagnosis is unknown. Currently, the severity of OSA is based on the apnea-hypopnea index (AHI), but its prognostic relevance has raised concerns. The Baveno classification may allow a better stratification of severity and therapeutic guidance in OSA. METHODS Patients with AHI≥5/h in 2015, classified into Baveno groups A and B and non-eligible for PAP therapy at diagnosis and over 5 years, were analyzed. Patients were reclassified into Baveno groups (A-D) and changes in groups over 5 years were explored. Patients in Baveno groups C and D, who developed major cardiovascular comorbidities (CVC) or end-organ damage (EOD group), were compared with patients in Baveno groups A and B (non-EOD group). To identify predictors of the development of major CVC or EOD, a logistic regression analysis was performed. RESULTS There were 76 patients, 58% male, mean age 51.9 ± 10.1 years, mean body mass index (BMI) of 30.3 ± 5.0 kg/m2 and median AHI of 8.9 (5.9-12.0) events/h. At diagnosis, 46% and 54% of patients were classified into Baveno group A and group B, respectively. In total, 21% of patients developed major CVC or EOD (Baveno group C or D); higher age (p = 0.011) and BMI (p = 0.004) and a higher percentage of central apneas (p = 0.012) at diagnosis significantly predicted it, while sex, sleepiness, insomnia, AHI, ODI and T90 were not. CONCLUSIONS A significant percentage of patients non-eligible for PAP-therapy at diagnosis of OSA developed CVC or EOD; higher age and BMI and a higher percentage of central apneas were significant predictors.

Abstract
Microplastics are present in all parts of the ocean and can have deleterious effects on marine resources. The aim of this work was to map the presence of microplastics in commercial marine species such as bivalves (mussels Mytilus galloprovincialis and clams Scrobicularia plana), crabs (Carcinus maenas) as well as fish (Mullus surmuletus) to relate microplastics levels to pollution sources, assess possible impact on marine food chains and on human health. These species were collected from several sites of the Ria Formosa lagoon and along the south coast of Portugal. A quantitative assessment (number, size and color) and typology of microplastics were made in these species. Only one green fragment of polypropylene was detected in the gills of the crabs, while a blue polyethylene fragment was detected in the hepatopancreas of the mullets. Moreover, no microplastics were present in S. plana nor in the crabs whole soft tissues. Among mussels, 86% of microplastics were present from all sites and the number, size and color were site specific. Mussels from the west side of the coast (Sites 1-3) had the highest levels of MPs per mussel and per weight compared to the other sites, probably related to the impact of touristic activity, fishing gears, fresh water and sewage effluents along with the hydrodynamics of the area.

Abstract
Western diets are poor in healthy n3 polyunsaturated fatty acids, such as docosahexaenoic acid. Since microalga Aurantiochytrium sp. is rich in docosahexaenoic acid, a functional food based on lean yogurt and this microalga was tested. This study entailed characterizing the lipid fraction and determining the fatty acid bioaccessibility. The tested yogurts (control and 2% w/w, Aurantiochytrium sp.) had differences. Docosahexaenoic acid was not detected in the control product, but it was the second most important fatty acid in Aurantiochytrium sp. and Aurantiochytrium yogurt, 29.7 ± 0.4% and 18.7 ± 2.0%, respectively. Based on the fatty acid profile only, an amount of 158.7 g of Aurantiochytrium yogurt in wet weight terms would be required to ensure an appropriate intake of healthy fatty acids. Generally, the fatty acid bioaccessibility was not high, remaining below 60-70% in almost all cases. Considering the docosahexaenoic acid bioaccessibility (44 ± 3%), an amount of 360.7 g of Aurantiochytrium yogurt would be advisable. A reasonable dietary prescription would be a daily consumption of 125 ml of Aurantiochytrium yogurt.

Abstract
CLINICAL RELEVANCE Effective methods to control incipient caries lesions are needed. In this investigation, several methods provide encouraging results. SUMMARY This study aimed to evaluate in situ the inhibition of incipient caries lesion progression using different treatment protocols and to evaluate the effectiveness of fluorescence-based methods (DIAGNOdent, DIAGNOdent pen, and VistaProof fluorescence camera [FC]) in monitoring this process. The research was conducted in four phases: (1) at baseline, (2) after a first cariogenic challenge, (3) after treatment modalities, and (4) after a second cariogenic challenge. Sixteen volunteers used intraoral acrylic palatal appliances, each containing six enamel blocks (n=96). The cariogenic challenge was performed using a 20% sucrose solution over a 14-day period. The appliances were removed eight times a day and, upon removal, two drops of the solution were placed onto each enamel block. The enamel blocks were randomly assigned to three treatment groups: fluoride varnish ([FV] Duraphat; n=32), resin infiltrant ([RI] Icon; n=32), and adhesive system ([AS] Scotchbond; n=32). At the end of each phase, the surface microhardness (SMH) was measured, and two trained examiners evaluated the specimens using fluorescence-based methods. In addition, integrated mineral loss (ΔΔZ; vol%.min x μm) and lesion depth (ΔLD; μm) were evaluated using transverse microradiography. A two-way analysis of variance and a Tukey post hoc test were calculated (α=5%). Significant differences in SMH were observed according to the treatment, phases, and interaction of factors (p<0.001). Treatment with FV resulted in significantly higher SMH values in phases 3 and 4 compared to RI and AS, with the last two treatments resulting in similar values (p>0.05). The ΔΔZ value was similar for FV and AS but significantly higher for RI (p=0.016). ΔLD was not significantly different among the groups (p=0.126). Significant differences in the measurement of fluorescence for each fluorescence-based method were observed between each phase of the study (p<0.05). It can be concluded that all treatments were effective in inhibiting the in situ progression of incipient lesions, although to different degrees, with minor mineral loss changes observed for the AS and FV. Besides, all fluorescence-based methods tested, except for that using the FC device, were effective in monitoring caries lesion progression.

Transcriptomic and proteomic analysis of the underlying mechanisms of digestion of triacylglycerols and phosphatides and absorption and fate of fatty acids along the midgut of Musca domestica. COMPARATIVE BIOCHEMISTRY AND PHYSIOLOGY D-GENOMICS & PROTEOMICS 2021; 39:100826. [PMID: 33839527 DOI: 10.1016/j.cbd.2021.100826] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/29/2020] [Revised: 03/23/2021] [Accepted: 03/23/2021] [Indexed: 11/24/2022]
Abstract
Most dietary lipids are triacylglycerols (TAGs) and phosphatides that are digested by TAG lipases and phospholipases (PLIPs), respectively, originating fatty acids (FA). The genome of Musca domestica has genes coding for phospholipases A1 (1PLIP), A2 (2PLIP), B (BPLIP), and acid lipases (ALIP), as for proteins involved in activation, binding, and metabolism of FA, which expression in the larval midgut was evaluated by RNA-seq. Some of the codified proteins were identified in midgut microvillar-enriched membrane by proteomics. 1PLIPs are the most expressed PLIPs, mainly in anterior midgut whereas 2PLIPs, and BPLIP in middle and posterior midgut, and ALIPs between middle and posterior regions. Absorption of FAs is putatively accomplished by proteins involved in FA activation (acyl-CoA synthetases) found in microvillar-enriched membrane preparations. Furthermore, FA uptake could be enhanced by proteins that bind FAs (FA-binding proteins) and its activated form (acyl-CoA binding proteins) mainly expressed in posterior midgut. Activated FAs could have different fates: synthesis of diacylglycerol (DAG) and TAG through monoacylglycerol and glycerol-3-phosphate pathways; synthesis of phosphatides; energy source by β-oxidation. Most genes coding for enzymes of those routes is expressed mainly at the end of posterior midgut. Data suggest that phosphatides are digested in anterior midgut by Md1PLIPs, releasing lysophosphatides that emulsify fats to be digested by MdALIPs in the middle and posterior midgut. Most resulting FAs is absorbed in the posterior midgut, where they follow the synthesis of DAG, TAG, and phosphatides or are oxidized along the midgut, mainly in highly metabolic middle and posterior midgut regions.

Abstract
Abstract
Background
Chagas disease (CD) is a neglected tropical disease that affects mainly vulnerable population, whose majority has low ability to understand health information. This study aimed to assess the prevalence of health literacy (HL) and its association with sociodemographic, quality of life, health care aspects and worse clinical outcomes.
Methods
This is a cross-sectional study developed inside a cohort study (SaMi-Trop) including 1959 patients. It has been conducted in an endemic region to CD in Brazil. The eligible criteria for HL evaluation was the ability to read. The HL was assessed with SALPHA-18 scale and literacy was categorized in inadequate HL; adequate HL and; illiterate. Multiple models were adjusted using binary logistic regression, multinomial and beta regression models using the gamlss framework.
Results
Of the patients included, 1136 (74.1%) are illiterate. For HL assessment, only 397 managed to complete the HL evaluation. The prevalence of inadequate HL was 85.1% (338), only 59 patients (14.9%) had adequate HL. Our results are as following: 1) being illiterate increases the chance of using more drugs when compared to individuals with adequate HL - 1 or 2 drugs (OR: 1.96; CI: 1.06-3.62) and 3 to 4 medications (OR: 3.06; CI:1.44-6.52), to have hypertension (OR: 2.24; CI: 1.29-3.90), report an average self-perceived health (OR: 2.97; IC: 1.63-5.42) and report poor self-perceived health (OR: 3.67; CI: 1.71-7.89); 2) inadequate literacy increases the chance of using 3 to 4 medications (OR: 2.26; CI: 1.04-4.93) and report an average self-perceived health (OR: 2.48; CI: 1.34-4.62); 3) Illiterate patients present worst quality of life scores in Physical (OR: 0,730; CI: 0,583-0,914), Psychological (OR: 0,671; CI: 0,544-0,828) and Environmental (OR: 0,727; CI: 0,601-0,880) domains.
Conclusions
We found a high prevalence of inadequate HL; it was associated with worse clinical outcomes and poor self-perceived health.
Key messages
Our findings reinforce the importance of improving health communication in CD patients seeking to avoid unfavorable outcomes. A high prevalence of inadequate health literacy was observed in our study, which can impact the self-care ability of patients with CD.

Abstract
Abstract
Problem
The burden of disease for oncological problems is significant in Portugal. Population-based screenings, such as colorectal cancer screening (CCS) with faecal occult blood tests (FIT) is a priority program to reduce the burden of disease and a cost-effectiveness measure.
Description problem
Algarve CCS started in 2017,to early detect colorectal cancer reducing morbidity and mortality. Screening strategy to detect and remove cancer precursors (adenomas) and early cancer detection with less invasive treatment using a non-invasive stool test was selected. A quantitative faecal immunochemical test for haemoglobin (FIT) with higher sensitivity for adenoma and cancer, specific for human globin with no dietary restriction, with a single sample screening is considered a test with higher participation. Target population all gender from 50 to 75 are invited to participate in the CCS by letter. Screening interval is 2 years and FIT cut-off- 117 (ng Hb/mL). Software was used to manage all CCS. Health units distribute the test and a flyer. All FIT-positive were invited to do a full colonoscopy at University Hospital.
Results
A preliminary descriptive analysis (2017/2019) was made. After exclusions 25017 of target population participate 34,4%(n = 8594),27.5%(n = 6883) submitted it for analysis, 3.9% (n = 266) had positive FIT and were invited for a full colonoscopy with 57.5% (n = 153)participation rate. Cancer detection was 0.9‰ and adenomas detection rate was 9.9%. FIT positive with colonoscopy 3.9% (n = 6) had carcinoma and 44.4% (n = 68) had adenoma.
Lessons
Some operational changes were made to improve participants and professionals adherence to CCS. Pathology observed in the positive cases, reinforce the need to implement strategies to increase literacy, raise public awareness, keep the screening test and improve accessibility of health facilities.
Key messages
The importance of a colorectal cancer early diagnosis prevent aggressive interventions in a precancerous phase. The importance of a colorectal cancer early diagnosis improves survival and population quality of life.

Abstract
Abstract
Issue
Cervical Cancer (CC) is the 7th most frequent and the 2nd most common in women. The standardized mortality rate, in Portugal is 2.3/100000 inhabitants and Algarve is the region with highest rate, 4.9/100000.
Description
Programme started in 2010. Population-based screening programme can reduce incidence, mortality and morbidity with an early diagnosis, preventing aggressive interventions in precancerous phase, improving survival and life quality. Target population, woman age 25-64.are invited to primary test liquid-based cytology (ThinPrep) every 3 years. Health Centres are responsible for select, invite, collect samples and send to Hospital laboratory. For positives, a cervical pathology consultation is required. National Guidelines now indicates DNA testing for human papillomavirus (HPV) as primary screening test, each 5 years, to woman age 25 to 60 and screening program changes will be implemented in 2019 with improved response time and lower cost.
Results
Since 2010 the target population has increased 12% every 2 years and the adhesion rate increased ≈68% and≈108%. Nevertheless the 3rd cycle has showed 10,8% (17.975) adhesion rate. Most women 16.112 (89.6%) had a negative diagnosis, 503 (2,8%) is ASC-US + (HPV test), and 761(4,2%) had a cervical pathology consultation. From those, 117 (15.4%) had a LSIL, 69 (9,1%) HSIL and 2(0,3%) cancer. Cancer detection rate is 0,1 ‰.
Lessons
The small adhesion rate particularly by aged women, the users unfriendly Information System and direct screening health units management are some of the issues that requires improvement. Also population literacy, self-sampling vaginal fluid and clinical meetings are some of the options to improve screening program.
Key messages
Cervical Cancer early diagnosis prevent aggressive interventions in a precancerous phase, improves survival and life quality. Better access and health communication are major points in screening programs.

Abstract
Issue
Breast cancer is the 2nd cause of death for women in Portugal and 6000 new cases are detected annually. The prognosis is better for women whose cancers are detected earlier.
Description
Algarve BCS begin in 2005 using a digital mammography with 2 incidences/breast with double reading and consensus by a 3rd radiologist. Each 2 years women age 50 to 69, are invited to a Mobile Unit to do the mammography, a partnership with Algarve Oncologic Association. In 2017, direct digital mammography with Tomosynthesis(DDMT)was implemented. This technique increase cancer detection, reduction of false positives, false negatives and radiation dose. Diagnostic accuracy is better and also improves accessibility to the most vulnerable population groups to this technology.
Results
BCS covers 100% of the region and the mobile unit is user friendly for women with mobility impairment. Adhesion rate is > 62%. Is the 1st screening using Tomosynthesis in Portugal.Preliminary results show that the confirmation rate increased (10 %), the detection rate per 1.000 women also increased and the positive predictive value >95%.
Costs associated with the program decrease and less number of women called for false positives is observed. The number of positive mammograms increased, due to diagnostic acuity, with better visualization of the breast, namely in the patterns of greater mammary density; which leads to an improvement in further assessment rates.
Lessons
The technique increases the adhesion rate, with the same human resources. The decrease of the false positives improves the number of women send to further assessment and Senology Center. Earlier diagnoses, less aggressive treatments, and a higher survival rate are also expected.
Messages- Using this technology is expected that cancer diagnosis will be earlier, more reliable and wiht higher survival rate for this disease. The possibility of a population based screening with DDMT is an opportunity to reduce inequalities in the region.

Abstract
Microalgae have strong potential as novel sources of nutraceuticals, as they contain significant amounts of highly valuable bioactive compounds. This study focuses on the bioprospection of biomass of the microalga Isochrysis galbana and its extracts (aqueous and ethanolic), determining total polyphenols, laminarin, fucoxanthin, coenzyme Q10, and β-carotene contents, and also assessing several biological activities (antioxidant, cytotoxicity, and hypocholesterolemic). I. galbana exhibited high phenolic content, both in aqueous and ethanolic extracts. The microalgal freeze-dried biomass presented a low laminarin content and higher content of fucoxanthin (6.10 mg per g dw), and relevant β-carotene and Coenzyme Q10 contents were detected. I. galbana aqueous extracts presented a high antioxidant capacity (approximately 90% inhibition by the ABTS method). Furthermore, I. galbana biomass and ethanolic extract showed significant cytotoxicity against HeLa human cervical cancer cells, with IC50 values of 0.32 and 0.28 mg ml-1 respectively, demonstrating potential for further anticancer studies. The aqueous extract of I. galbana induced a significant decrease of cholesterol absorption through Caco-2 monolayers, modelling the human intestinal barrier, which suggests that it may contribute to decreasing the dietary cholesterol absorption.

Are shallow-water shrimps proxies for hydrothermal-vent shrimps to assess the impact of deep-sea mining? MARINE ENVIRONMENTAL RESEARCH 2019; 151:104771. [PMID: 31420206 DOI: 10.1016/j.marenvres.2019.104771] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/21/2019] [Revised: 08/02/2019] [Accepted: 08/04/2019] [Indexed: 06/10/2023]
Abstract
Polymetallic seafloor massive sulphide deposits are potential targets for deep-sea mining, but high concentrations of metals (including copper - Cu) may be released during exploitation activities, potentially inducing harmful impact. To determine whether shallow-water shrimp are suitable ecotoxicological proxies for deep-sea hydrothermal vent shrimp the effects of waterborne Cu exposure (3 and 10 days at 0.4 and 4 μM concentrations) in Palaemon elegans, Palaemon serratus, and Palaemon varians were compared with Mirocaris fortunata. Accumulation of Cu and a set of biomarkers were analysed. Results show different responses among congeneric species indicating that it is not appropriate to use shallow-water shrimps as ecotoxicological proxies for deep-water shrimps. During the evolutionary history of these species they were likely subject to different chemical environments which may have induced different molecular/biochemical adaptations/tolerances. Results highlight the importance of analysing effects of deep-sea mining in situ and in local species to adequately assess ecotoxicological effects under natural environmental conditions.

Domain structure and expression along the midgut and carcass of peritrophins and cuticle proteins analogous to peritrophins in insects with and without peritrophic membrane. JOURNAL OF INSECT PHYSIOLOGY 2019; 114:1-9. [PMID: 30735683 DOI: 10.1016/j.jinsphys.2019.02.002] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/14/2018] [Revised: 01/22/2019] [Accepted: 02/04/2019] [Indexed: 06/09/2023]
Abstract
Most insects have a peritrophic membrane (matrix) (PM) surrounding the food bolus. This structure, similarly to the cuticle, is mainly composed of chitin and proteins. The main proteins forming PM are known as peritrophins (PMP), whereas some of the cuticle proteins are the cuticle proteins analogous to peritrophins (CPAP). Both proteins are composed of one or more chitin binding peritrophin-A domain (CBD) and no other recognized domain. Furthermore, insects containing PM usually have two chitin synthase (CS) genes, one mainly expressed in carcass and the other in midgut. In this work we identified PMP, CPAP and CS genes in the genome of insects from the Polyneoptera, Paraneoptera and Holometabola cohorts and analyzed their expression profile in different species from each group. In agreement with the absence of PM, we observed less CBD-containing proteins and only one CS gene in the genome of Paraneoptera species, except for the Phthiraptera Pediculus humanus. The lack of PM in Paraneoptera species was also confirmed by the micrographs of the midgut of two Hemiptera species, Dysdercus peruvianus and Mahanarva fimbriolata which agreed with the RNA-seq data of both species. Our analyses also highlighted a higher number of CBD-containing proteins in Holometabola in relation to the earlier divergent Polyneoptera group, especially regarding the genes composed of more than three CBDs, which are usually associated to PM formation. Finally, we observed a high number of CBD-containing proteins being expressed in both midgut and carcass tissues of several species, which we named as ubiquitous-CBD-containing proteins (UCBP), as their function is unclear. We hypothesized that these proteins can be involved in both cuticle and PM formation or that they can be involved in immune response and/or tracheolae formation.

Environmental relevant levels of the cytotoxic drug cyclophosphamide produce harmful effects in the polychaete Nereis diversicolor. THE SCIENCE OF THE TOTAL ENVIRONMENT 2018; 636:798-809.

Abstract
Cytotoxic drugs applied in chemotherapy enter the aquatic environment after patient's metabolism and excretion, in both main compounds and their respective metabolites. The increased consumption and discharge of these drugs raise concern on the genotoxic burden to non-target aquatic species, due to their unselective action on DNA. Settlement and adsorption of cytotoxic drugs to aquatic sediments pose risks to benthic species through chronic exposure. The aim of the present study was to assess the effects induced by the anticancer drug cyclophosphamide (CP) on the polychaete Nereis diversicolor, after 14 days of exposure to environmental relevant concentrations (10, 100, 500 and 1000 ng L-1). Burrowing impairment, neurotoxicity (Acetylcholinesterase - AChE activity), oxidative stress (superoxide dismutase - SOD; catalase - CAT; glutathione peroxidases - GPXs activities), biotransformation (glutathione-S-transferases - GST), oxidative damage (lipid peroxidation - LPO) and genotoxicity (DNA damage) were assessed. Burrowing impairments were higher at the lowest CP concentrations tested. The higher CP levels tested (500 and 1000 ng L-1) induced a significant inhibition on the enzymatic antioxidant system (SOD, GPx) and on GST activity. DNA damage was also significant at these concentrations as an outcome of CP metabolism, and high levels of oxidative damage occurred. The results showed that the prodrug CP was metabolically activated in the benthic biological model N. diversicolor. In addition to the potential cytotoxic impact likely to be caused in aquatic species with similar metabolism, N. diversicolor proved to be reliable and vulnerable to the cytotoxic mode of action of CP, even at the lower doses.

Abstract
We propose spin valves where a 2D nonmagnetic conductor is intercalated between two ferromagnetic insulating layers. In this setup, the relative orientation of the magnetizations of the insulating layers can have a strong impact on the in-plane conductivity of the 2D conductor. We first show this for a graphene bilayer, described with a tight-binding model, placed between two ferromagnetic insulators. In the antiparallel configuration, a band gap opens at the Dirac point, whereas in the parallel configuration, the graphene bilayer remains conducting. We then compute the electronic structure of graphene bilayer placed between two monolayers of the ferromagnetic insulator CrI_{3}, using density functional theory. Consistent with the model, we find that a gap opens at the Dirac point only in the antiparallel configuration.

Abstract
Most insects have a gut lined with a peritrophic membrane (PM) consisting of chitin and proteins, mainly peritrophins that have chitin-binding domains. The PM is proposed to originate from mucus-forming mucins (Mf-mucins), which acquired a chitin-binding domain that interlocked with chitin, replacing mucus in function. We evaluated the expression of Mf-mucins and peritrophins by RNA-sequencing (RNA-seq) throughout the midgut of four distantly related insects. Mf-mucins were identified as proteins with high o-glycosylation and a series of uninterrupted Pro/Thr/Ser residues. The results demonstrate that the mucus layer is widespread in insects, and suggest that insect Mf-mucins are derived from those found in other animals by the loss of the cysteine knot and von Willebrand domains. The data also support a role of Mf-mucins in protecting the middle midgut of Musca domestica against acidic buffers. Mf-mucins may also produce a jelly-like material associated with the PM that immobilizes digestive enzymes in Spodoptera frugiperda. Peritrophins with a domain similar to Mf-mucins may be close to the ancestor of peritrophins. Expression data of peritrophins and chitin synthase genes throughout the midgut of M. domestica, S. frugiperda and Tenebrio molitor indicated that peritrophins were incorporated along the PM, according to their preferential sites of formation. Finally, the data support the view that mucus has functions distinct from the PM.

A physiologically-oriented transcriptomic analysis of the midgut of Tenebrio molitor. JOURNAL OF INSECT PHYSIOLOGY 2017; 99:58-66.

Abstract
Physiological data showed that T. molitor midgut is buffered at pH 5.6 at the two anterior thirds and at 7.9 at the posterior third. Furthermore, water is absorbed and secreted at the anterior and posterior midgut, respectively, driving a midgut counter flux of fluid. To look for the molecular mechanisms underlying these phenomena and nutrient absorption as well, a transcriptomic approach was used. For this, 11 types of transporters were chosen from the midgut transcriptome obtained by pyrosequencing (Roche 454). After annotation with the aid of databanks and manual curation, the sequences were validated by RT-PCR. The expression level of each gene at anterior, middle and posterior midgut and carcass (larva less midgut) was evaluated by RNA-seq taking into account reference sequences based on 454 contigs and reads obtained by Illumina sequencing. The data showed that sugar and amino acid uniporters and symporters are expressed along the whole midgut. In the anterior midgut are found transporters for NH3 and NH4+ that with a chloride channel may be responsible for acidifying the lumen. At the posterior midgut, bicarbonate-Cl- antiporter with bicarbonate supplied by carbonic anhydrase may alkalinize the lumen. Water absorption caused mainly by an anterior Na+-K+-2Cl- symporter and water secretion caused by a posterior K+-Cl- may drive the midgut counter flux. Transporters that complement the action of those described were also found.

Abstract
In light of deep-sea mining industry development, particularly interested in massive-sulphide deposits enriched in metals with high commercial value, efforts are increasing to better understand potential environmental impacts to local fauna. The aim of this study was to assess the natural background levels of biomarkers in the hydrothermal vent shrimp Rimicaris exoculata and their responses to copper exposure at in situ pressure (30MPa) as well as the effects of depressurization and pressurization of the high-pressure aquarium IPOCAMP. R. exoculata were collected from the chimney walls of the hydrothermal vent site TAG (Mid Atlantic Ridge) at 3630m depth during the BICOSE cruise in 2014. Tissue metal accumulation was quantified in different tissues (gills, hepatopancreas and muscle) and a battery of biomarkers was measured: metal exposure (metallothioneins), oxidative stress (catalase, superoxide dismutase, glutathione-S-transferase and glutathione peroxidase) and oxidative damage (lipid peroxidation). Data show a higher concentration of Cu in the hepatopancreas and a slight increase in the gills after incubations (for both exposed groups). Significant induction of metallothioneins was observed in the gills of shrimps exposed to 4μM of Cu compared to the control group. Moreover, activities of enzymes were detected for the in situ group, showing a background protection against metal toxicity. Results suggest that the proposed method, including a physiologically critical step of pressurizing and depressurizing the test chamber to enable the seawater exchange during exposure to contaminants, is not affecting metal accumulation and biomarkers response and may prove a useful method to assess toxicity of contaminants in deep-sea species.

Abstract
IntroductionPerinatal mental illness is one of the most frequent complications of pregnancy and the postpartum period. During the puerperium, the risk of developing a mental disease, such as a psychotic episode, is higher than in any other time in a woman's life.ObjectivesThe two main objectives are to describe a case series of 4 patients diagnosed with pospartum psychosis, and to synthesize the most important facets of this mental illness based on a literature review.AimsThe aim is to provide an overview of the clinical and epidemiological aspects of postpartum psychosis.MethodsThe four clinical cases are presented by describing the similar as opposed to the differential aspects between all patients, using the information obtained through successive clinical interviews and the case file. Research was accomplished through Clinical Key and PubMed (2005-2015) using the keywords: postpartum psychosis.ResultsIn all four cases, the patients developed symptoms of sleep disturbance, mood fluctuation, altered thinking process with delusions or obsessions, and bizarre behaviours. This occurred within the first four weeks after labour, which was in all cases an obstrutced labour. The data suggests that postpartum psychosis is a presentation of bipolar disorder. Clinical aspects and risk factors related to this perinatal complication all coincide with the cases presented.ConclusionsPostpartum psychosis is a rare presentation of perinatal mental illness. However, it presents itself, as a psychiatric emergency, and the early and correct assessment are crucial to reset the development of the mother–child bond.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Insect midgut α-mannosidases from family 38 and 47 with emphasis on those of Tenebrio molitor. INSECT BIOCHEMISTRY AND MOLECULAR BIOLOGY 2015; 67:94-104.

Abstract
α-Mannosidases are enzymes which remove non-reducing terminal residues from glycoconjugates. Data on both GH47 and GH38 (Golgi and lysosomal) enzymes are available. Data on insect midgut α-mannosidases acting in digestion are preliminary and do not include enzyme sequences. Tenebrio molitor midgut α-mannosidases were separated by chromatography into two activity peaks: a major (Man1) and a minor (Man2). An antibody generated against a synthetic peptide corresponding to a sequence of α-mannosidase fragment recognizes Man2 but not Man1. That fragment was later found to correspond to TmMan2 (GenBank access KP892646), showing that the cDNA coding for Man2 is actually TmMan2. TmMan2 codes for a mature α-mannosidase with 107.5 kDa. Purified Man2 originates after SDS-PAGE one band of about 72 kDa and another of 51 kDa, which sums 123 kDa, in agreement with gel filtration (123 kDa) data. These results suggest that Man2 is processed into peptides that remain noncovalently linked within the functional enzyme. The physical and kinetical properties of purified Man1 and Man2 are similar. They have a molecular mass of 123 kDa (gel filtration), pH optimum (5.6) and response to inhibitors like swainsonine (Man1 Ki, 68 nM; Man2 Ki, 63 nM) and deoxymannojirimycin (Man1 Ki, 0.12 mM; Man2 Ki, 0.15 mM). Their substrate specificities are a little different as Man2 hydrolyzes α-1,3 and α-1,6 bonds better than α-1,2, whereas the contrary is true for Man1. Thus, they pertain to Class II (GH38 α-mannosidases), that are catabolic α-mannosidases similar to lysosomal α-mannosidase. However, Man2, in contrast to true lysosomal α-mannosidase, is secreted (immunocytolocalization data) into the midgut contents. There, Man2 may participate in digestion of fungal cell walls, known to have α-mannosides in their outermost layer. The amount of family 38 α-mannosidase sequences found in the transcriptome (454 pyrosequencing) of the midgut of 9 insects pertaining to 5 orders is perhaps related to the diet of these organisms, as suggested by a large number of lysosomal α-mannosidase in the T. molitor midgut.

Benefits and risks associated with consumption of raw, cooked, and canned tuna (Thunnus spp.) based on the bioaccessibility of selenium and methylmercury. ENVIRONMENTAL RESEARCH 2015; 143:130-137.

Abstract
The Se, Hg, and methylmercury (MeHg) levels in raw, cooked (boiled and grilled), and canned tuna (Thunnus spp.) were determined before and after an in vitro digestion, thereby enabling the calculation of the respective bioaccessibility percentages. A risk-benefit evaluation of raw and canned tuna on the basis of the Se and MeHg data was performed. Selenium bioaccessibility was high in tuna, though slightly lower in canned than in raw products. Mercury levels were high in raw and cooked tuna. Hg bioaccessibility percentages were low (39-48%) in the cooked tuna and even lower (<20%) in canned tuna. For the bioaccessible fraction, all molar Se:MeHg ratios were higher than one (between 10 and 74). A probabilistic assessment of MeHg risk vs Se benefit showed that while a weekly meal of canned tuna presents very low risk, raw, boiled, and grilled tuna consumption should not exceed a monthly meal, at least, for pregnant and nursing women.
