RESUMO
Considerable attention has been paid to address methodological concerns related to measurements of embolism in conduits of angiosperm xylem. A fast, easy, and cheap method is based on gas extraction measurements from dehydrating samples to obtain pneumatic vulnerability curves (VCs). Here, we tested the assumption that cutting open conduits leads to gas-filled lumina when these are cut in air at fairly high water potentials, which is required to detect embolism in intact conduits. We performed VCs with the Pneumatron for 12 angiosperm species, and extracted sap from cut-open vessels in branches of nine species under early stages of branch dehydration. The optical method was applied to Citrus plants as an alternative reference method to estimate embolism resistance. We found an increase in gas discharge during early stages of dehydration, which affected the pneumatic VCs for most of the species studied. Xylem sap residue was not absorbed immediately by surrounding tissue in cut-open conduits in six of the nine species, but gradually disappeared over time during progressive dehydration. The amount of gas discharged increased until all residual sap was absorbed, and was not related to embolism. We conclude that residual xylem sap in cut-open conduits affects early stages of pneumatic VCs, and represents a novel artefact that can easily be corrected for. Yet, it remains unclear why exactly the air-water meniscus in cut-open conduits did not fully withdraw to the conduit end wall in most species. By analysing the slope of VCs over time, we could improve estimations of embolism resistance, as evidenced by a strong agreement between the pneumatic and the optical methods. Since residual sap in cut-open conduits of some species could slightly underestimate embolism resistance, we propose to apply a correction for this artefact based on the high time resolution measurements taken with a Pneumatron.
RESUMO
Emerald tree boas (Corallus batesii) are boids that in situ occurs in forested habitats in the Amazon Basin. The mycobacterial species can infect reptiles but the species Mycolicibacterium fortuitum was identified only in feces samples of ex situ Python regius and was isolated from granulomatous lesions of an ex situ Iguana iguana when was still part of the genus Mycobacterium. This article aims to report a mycobacteria infection case in a female Corallus batesii kept under human care. The animal presented apathy and 2 months of anorexia, being found dead. The necropsy revealed presence of tracheal and pulmonary nodules besides multifocal, bacterial, granulomatous pneumonia. After Fite-Faraco histochemical staining, immunohistochemistry, semi-nested polymerase chain reaction (PCR) and genetic sequencing the Mycolicibacterium fortuitum complex was diagnosed with 99.54% of nucleotide similarity. This mycobacterial species was already pointed out as an important nosocomial pathogen and more studies are necessary to explore their zoonotic potential.

BACKGROUND: The corn leafhopper, Dalbulus maidis, is an important pest in Brazil. While chemical control has traditionally been the cornerstone for managing this pest, field control failures have been reported for some insecticides. To understand if these failures are due to resistance, we evaluated the susceptibility of 11 field-collected populations of D. maidis to major insecticides during the 2021-2022 crop seasons in Brazil using concentration-mortality bioassays. Additionally, we employed diagnostic concentration bioassays and foliar sprays at label-recommended rates in 8-10 populations collected during the 2022-2023 crop seasons. RESULTS: High susceptibility to methomyl, carbosulfan and acephate was observed on concentration-mortality bioassays across all populations tested with resistance ratio (RR) based on LC50 <10-fold, except for one population from Bahia State that exhibited reduced susceptibility to methomyl (RR = 17.5). On the other hand, all populations exhibited reduced susceptibility to bifenthrin, acetamiprid, and imidacloprid, with RR ranging from 90 to 2000-fold. This reduced susceptibility to neonicotinoid and pyrethroid insecticides was further confirmed at diagnostic concentrations based on LC99 of the susceptible strain, with survival rates >20% and in foliar sprays with mortality rates <80%. Most populations exposed to acephate and carbosulfan exhibited low survival rates at diagnostic concentrations (<5%) and high mortality rates in foliar sprays (>80%). CONCLUSIONS: The reduced susceptibility to pyrethroid and neonicotinoid insecticides likely explain the field failures in controlling D. maidis populations in Brazil. This study represents the first large-scale susceptibility monitoring of D. maidis to insecticides, and the results will contribute to decision-making regarding the management of this pest. © 2024 Society of Chemical Industry.

Embolism resistance of xylem tissue varies among species and is an important trait related to drought resistance, with anatomical attributes like pit membrane thickness playing an important role in avoiding embolism spread. Grafted Citrus trees are commonly grown in orchards, with the rootstock being able to affect the drought resistance of the whole plant. Here, we evaluated how rootstocks affect the vulnerability to embolism resistance of the scion using several rootstock/scion combinations. Scions of 'Tahiti' acid lime, 'Hamlin', 'Pera' and 'Valencia' oranges grafted on a 'Rangpur' lime rootstock exhibit similar vulnerability to embolism. In field-grown trees, measurements of leaf water potential did not suggest significant embolism formation during the dry season, while stomata of Citrus trees presented an isohydric response to declining water availability. When 'Valencia' orange scions were grafted on 'Rangpur' lime, 'IAC 1710' citrandarin, 'Sunki Tropical' mandarin or 'Swingle' citrumelo rootstocks, variation in intervessel pit membrane thickness of the scion was found. The 'Rangpur' lime rootstock, which is known for its drought resistance, induced thicker pit membranes in the scion, resulting in higher embolism resistance than the other rootstocks. Similarly, the rootstock 'IAC 1710' citrandarin generated increased embolism resistance of the scion, which is highly relevant for citriculture.

BACKGROUND: The Vieira's titi monkey (Plecturocebus vieirai) was recently described and characterized as endemic to Brazil. According to the IUCN red list, this species is classified as critically endangered (CR). At the date of the publication of this manuscript, there are no published data on the health aspects of this species. METHODS: For this study, the necropsy, and histopathological data of the mortality of P. vieirai at Sorocaba Zoo (São Paulo, Brazil) were collected and analyzed. RESULTS: Causes of death diagnosed included disorders of the urinary, gastrointestinal, immune, and circulatory systems. CONCLUSIONS: This study provides information regarding the pathological conditions of P. vieirai and points to urinary and gastrointestinal diseases as the main causes of death in this species at Sorocaba Zoo. These results can help veterinarians who have this species under their care diagnose and deal with it more quickly, increasing the probability of survival.

Bone lesions have the capacity for regeneration under normal conditions of the bone metabolism process. However, due to the increasing incidence of major traumas and diseases that cause bone-mineral deficiency, such as osteoporosis, scaffolds are needed that can assist in the bone regeneration process. Currently, natural polymeric scaffolds and bioactive nanoparticles stand out. Therefore, the objective of the study was to evaluate the osteoregenerative potential in tibiae of healthy and ovariectomized rats using mineralized collagen and nanohydroxyapatite (nHA) scaffolds associated with elastin. The in-vivo experimental study was performed with 60 20-week-old Wistar rats, distributed into non-ovariectomized (NO) and ovariectomized (O) groups, as follows: Controls (G1-NO-C and G4-O-C); Collagen with nHA scaffold (G2-NO-MSH and G5-O-MSH); and Collagen with nHA and elastin scaffold (G3-NO-MSHC and G6-O-MSHC). The animals were euthanized 6 weeks after surgery and the samples were analyzed by macroscopy, radiology, and histomorphometry. ANOVA and Tukey tests were performed with a 95% CI and a significance index of p < 0.05. In the histological analyses, it was possible to observe new bone formed with an organized and compact morphology that was rich in osteocytes and with maturity characteristics. This is compatible with osteoconductivity in both matrices (MSH and MSHC) in rats with normal conditions of bone metabolism and with gonadal deficiency. Furthermore, they demonstrated superior osteogenic potential when compared to control groups. There was no significant difference in the rate of new bone formation between the scaffolds. Ovariectomy did not exacerbate the immune response but negatively influenced the bone-defect repair process.

BACKGROUND: The estimated prevalence of post-traumatic osteoarthritis (PTOA) is 10-12% and in this study 12.4%. Different knee and hip injuries have been identified as risk factors for PTOA, but there is no consensus regarding the most painful and disabling injuries. Identifying these injuries might help in the prevention of PTOA. Additionally, patients with PTOA have a higher risk for complications after arthroplasty than patients with primary OA, perhaps due to differences in the profile and comorbidity that might help to explain the difference. This work aims 1) to identify the most common past injuries associated with the most painful and disabling PTOA cases in non-athlete patients and 2) to compare the comorbidities and characteristics between PTOA and primary OA. METHODS: Retrospective hospital-based cohort study with 1290 participants with joint complaints or who received arthroplasty. Medical records included demographic information, diagnosis, medication, smoking, alcohol history and comorbidities. Data from January 2012 orthopaedic consults till December 2019 was reviewed and had the type and date of injury, pain score by the numerical rating scale and walking disability. Odds Ratio (OR) and 95% confidence intervals are presented. RESULTS: There were 641 cases with primary OA (65% females) and 104 with PTOA (61% males). Patients with PTOA were 7.5 years younger (P < 0.001), reported more alcohol consumption (P = 0.01) and had higher odds of osteoporotic fractures (OP) and psychosis than patients with primary OA (OR = 2.0, CI = 1.06-3.78 and OR = 2.90, CI = -0.91-9.18, respectively). Knee fractures were most common in males and hip fractures in females (31% and 37.5%, respectively, P < 0.005). The PTOA-associated injuries with the highest pain and disability scores were meniscal injuries and hip fractures. Besides, in the group with primary OA, there were more diabetes, hypertension and hypothyroidism cases than in PTOA. However, after adjustment, differences were only significant for diabetes (ORadj = 1.78, CI = 1.0-3.2). CONCLUSIONS: Past meniscal injuries and hip fractures were the most relevant PTOA-associated injuries regarding pain and walking disability. This, together with differences in their profile when compared with primary OA, might help to decide the orthopaedic management of these injuries to prevent complications such as PTOA and recurrence, with appropriate preoperative planning, surgery choice and comorbidity treatment.

The present case is the first description of a co-infection with canine distemper virus (CDV) and canine adenovirus type 1 (CAdV-1) in a free-living hoary fox pup from Brazil. The animal was found and rescued with poor body condition, dehydration, incoordination, ataxia, excessive vocalization, and "blue eyes" phenomenon. Despite the efforts, euthanasia was elected due to worsening clinical signs and poor prognosis. Pathologic examination revealed a mild, acute, random, necrotizing hepatitis, acute bronchopneumonia, hydrocephalus, corneal edema with epithelium degeneration, and acidophilic intracytoplasmatic inclusion bodies in different epithelial cells types with rare syncytial. Through immunohistochemistry, CDV antigen was observed in the tongue, trachea, lungs, liver, spleen, stomach, intestine and urinary bladder. Adenovirus antigen was identified in the nucleus of scattered hepatocytes. Polymerase chain reaction and sequencing demonstrated high similarity with CAdV-1 and wild-type strain of CDV close related to Brazilian viral lineages isolated from domestic dogs. Disease surveillance in wildlife animals is essential to assess possible conservation threats and consider the implementation of mitigation or control measures.

Entomopathogenic fungi, widely available biological agents used to control agricultural pests, are sporadically reported to cause focal or disseminated infection in reptiles and mammals, including humans. This study summarizes the clinical presentation, histopathological and molecular findings by panfungal polymerase chain reaction and sequencing of four cases of hypocrealean fungal infections in captive common green iguanas (Iguana, iguana). One case of granulomatous pneumonia, hepatitis and serositis was related to Metarhizium flavoviride complex infection. Two disseminated fungal infection cases, with scarce inflammatory cell infiltration, were caused by Beauveria bassiana while there was one case of multifocal granulomatous and necrotizing pneumonia by Purpureocillium spp. To the best of our knowledge, this is the first report of fatal mycosis infection due to entomopathogenic fungi in captive common green iguanas.

Amebiasis is an important parasitosis that can affect reptiles, specially caused by protozoas of the genus Entamoeba, which include pathogenic or commensal species. Entamoeba invadens is the most common amoeba to cause serious disease and death in reptiles. This paper aims to report a case of a sudden death due to a disseminated infection by Entamoeba invadens in a red-footed tortoise (Chelonoidis carbonaria). The animal was brought to the Center for Management and Conservation of Wild Animals of the Fauna Division and found dead after being kept in an enclousure with other captive tortoises for 11 months. Macroscopic findings evidenced necrotizing typhlitis and proctitis and round yellow areas in the right lobe of liver parenchyma. In the histological examination, necrotizing and heterophilic enteritis and necrotizing hepatitis with macrovesicular degeneration of hepatocytes, associated with mixed inflammatory infiltrate were present. Both organs revealed numerous amoebic trophozoites, morphologically suggestive of the genus Entamoeba, and bacterial colonies. The agent was confirmed by PCR and Sanger DNA sequencing, which leads this study to be the first confirmed case report of E. invadens infection in Brazil in a red-footed tortoise.(AU)

OBJECTIVES: To determine the role of central obesity (CO) in the onset and severity of joint pain and in predicting cardiovascular disease (CVD) in subjects affected with osteoarthritis (OA). DESIGN: Retrospective analysis on the onset of OA joint pain and CO. Waist circumference (WC), Waist-to-height ratio andwaist-to-hip ratio (WHR) were measured at the interview and defined according to the WHO criteria. Cross-sectional analyses on the association of comorbidities, including CVD, pain severity (number of joints and pain score) and CO. SETTINGS AND PARTICIPANTS: Medical records and interviews of a hospital cohort study of 609 patients with OA. Analyses included analysis of variance, mean differences (MDs), SE and logistic regression. Areas under the receiver operating characteristic curve (AUROC) compared the predictive value of the sex-specific CVD models. OUTCOME MEASURES: Onset of OA joint pain (years) and severity according to body mass index (BMI) and WC categories. Predictive value of WC for CVD by sex. Education level, disability, smoking and alcohol use were used to adjust the analysis. RESULTS: Subjects with OA and CO by WHR started 2 years earlier with pain symptoms and had more joints affected than those without CO (MD=1.96 years, SE=0.95, p=0.04 and MD=0.32, SE=0.15 and p=0.04, respectively). Age and hypertension were associated with CVD in both genders, and NSAIDs use only in males. In addition, respiratory disease, hypercholesterolaemia, stairs difficulty, a wider WC and obesity were significant risk factors in females, improving 12.7% in the prediction of CVD cases, compared with only age and BMI (AUROCC=0.793 and 0.666, respectively, p=0.03 for the difference between AUROCs). CONCLUSION: CO is associated with the onset of joint pain, and all pain analysed variables. CO has a role in CVD in women affected with OA and might help predict CVD cases.

Abstract Background Infective endocarditis (IE) is a disease with high morbimortality and an increasing incidence. With improved diagnosis and treatment, a number of epidemiological changes have been reported over time. Objectives We sought to describe the epidemiological profile, mortality predictors, and analysis of a possible microbiological transition in patients admitted to three tertiary centers in Brazil. Methods In this cross-sectional retrospective study, data from 211 patients with definite or probable IE were analyzed according to the modified Duke criteria between 2003 and 2017. The association between categorical variables was assessed using the chi-square or Fisher's exact test, and binary logistic models were built to investigate mortality. We considered p <0.05 statistically significant. Results The median age of the sample was 48 (33-59) years old, 70.6% were men, and the most prevalent pathogen was Staphylococcus spp. (19%). Mortality was 22.3%, with increasing age being the leading risk factor for death (p = 0.028). Regarding the location of the disease, native valves were the most affected site, with the aortic valve being more affected in men than women (p = 0.017). The mean number of cases of Staphylococcus spp. (τ = 0.293, p = 0.148) and Streptococcus spp. (τ = -0.078, p = 0.727) has remained stable over the years. Conclusion No trend towards reduced or increased mortality was evident between 2003 and 2017. Although Staphylococcus spp. were the most prevalent pathogen, the expected epidemiological transition could not be observed.

Brazilian porcupine poxvirus (BPoPV) is a new poxvirus recently described in porcupines (Coendou prehensilis) from Brazil. Herein, we described a free-ranging adult male Coendou (Sphiggurus) spinosus rescued after being found lethargic on the ground in a rural area. The animal presented crusty, edematous, and suppurative skin lesions on the face, tail, and perineum, and yellowish ocular secretion. The diagnosis was performed by histopathology, transmission electron microscopy (TEM), PCR, and sequencing. Microscopically, proliferative and necrotizing dermatitis, subacute, multifocal with ballooning degeneration, and eosinophilic intracytoplasmic viral inclusion bodies were observed. TEM confirmed large brick-shaped virions inside the keratinocyte cytoplasm, measuring about 200-280 × 120-180 nm. Partial fragment of intracellular mature virion membrane protein gene and putative metalloproteinase gene was successfully amplified and sequenced, and the strain herein denoted IAL/21 V-102 was classified as BPoPV, showing 99.4% of nucleotide identity to the reference strain UFU/USP001. Enrofloxacin 10% (10 mg/kg) was administered every 24 h through intramuscular injection for 10 days, dipyrone/metamizole (25 mg/kg) every 24 h orally (PO) for 3 days, 0.5 ml (mL) of thymomodulin every 24 h PO for 30 days, and each 48 h for another 15 days. The lesions were cleaned and debrided every 15 days. Seventy-five days after the beginning of the treatment, the cutaneous lesions regressed, the animal gained weight, and was clinically stable. After treatment, the skin biopsy showed only mild epidermal acanthosis, intra-cellular edema, and mild lymphoplasmacytic perivascular dermatitis. No viral particles were observed by TEM and no poxviral DNA was amplified by PCR. This study documents the first case of confirmed and treated BPoPV infection in a hairy dwarf porcupine. The implemented therapeutic plan eliminated the infection and improved the general state of the animal.

The classical method to estimate the light conversion efficiency (εc) gives a single value for the whole crop cycle (εco) but does not reveal any variation along the growing season. We proposed the segmented approach to uncover such variations along sugarcane (Saccharum sp. hybrid) growth cycle. Our analyses revealed that longer sampling intervals could overestimate εco and that the segmented light conversion efficiency (εcs) varied between 0.09 and 5.39 g MJ-1 during the crop cycle. The εcs would provide insights on how the environment affects εc and how to increase biomass production through crop management practices.
