Diogenes syndrome (DS) is not a specific disease but a real neurobehavioral syndrome, characterized by severe domestic squalor, pathological hoarding, lack of insight into the condition, and no need for help. DS can be secondary when associated to psychosis or bipolar disorder, or primary when it occurs as a single entity, usually in the elderly. DS is a clinically complex transnosographic syndrome for which multidimensional approaches need to be considered: medical, psychiatric, neurological, social, scientific, and ethical...

Gastrointestinal nematodes are the major cause of animal diseases, and the indiscriminate use of synthetic anthelmintic contributes to the development of drug resistance. Natural bioproducts are noteworthy since they have proved to be promising for alternative antiparasitic therapies. This study evaluated the in vitro effect of WSMoL (water soluble Moringa oleifera lectin) on hatching of eggs and on the development of early-stage larvae of gastrointestinal nematodes from naturally infected goats. In addition, the interference of WSMoL on activity of proteases was determined and the affinity of the lectin for glycosylated molecules of these parasites was investigated using fluorescein isothiocyanate (FITC)-labeled WSMoL...

Diogenes Syndrome (DS) is characterised by extreme self-neglect, domestic squalor, hoarding, social withdrawal, and lack of concern and shame for the individual's residential situation. This paper describes TD who was unable to identify emotional expressions of disgust and was borderline-impaired for facial recognition associated with perceptual difficulties. Problems interpreting expressions of disgust were interesting as TD was living in squalor, neglecting himself, and lacked concern for his circumstances...

Cytidine deaminase (MtCDA), encoded by cdd gene (Rv3315c), is the only enzyme identified in nucleotide biosynthesis pathway of Mycobacterium tuberculosis that is able to recycle cytidine and deoxycytidine. An M. tuberculosis knockout strain for cdd gene was obtained by allelic replacement. Evaluation of mRNA expression validated cdd deletion and showed the absence of polar effect. MudPIT LC-MS/MS data indicated thymidine phosphorylase expression was decreased in knockout and complemented strains. The cdd disruption does not affect M...

IQG-607 is an analog of isoniazid with anti-tuberculosis activity. This work describes the development and validation of an HPLC method to quantify pentacyano(isoniazid)ferrate(II) compound (IQG-607) and the pharmacokinetic studies of this compound in mice. The method showed linearity in the 0.5-50μg/mL concentration range (r=0.9992). Intra- and inter-day precision was <5%, and the recovery ranged from 92.07 to 107.68%. IQG-607 was stable in plasma for at least 30days at -80°C and, after plasma processing, for 4h in the auto-sampler maintained on ice (recovery >85%)...

BACKGROUND: Down's syndrome (DS) affects one per 700 live births and congenital heart disease (CHD) occurs in 40-60% of these patients. Contributing factors to the association between DS and CHD are being unraveled. Gender could be one of them. METHODS: We performed a meta-analysis of CHD prevalence in DS, separated by gender. Three search engines were used and 578 articles were reviewed. Twelve articles were included. RESULTS: Quantitative analysis showed a higher prevalence of CHD, particularly atrioventricular septal defects (AVSD), in female patients...

OBJECTIVE: Atopy is associated with asthma, but cross-sectional studies suggest this association may be weaker in older adults. It remains unclear if atopy predicts asthma later in adult life. We aimed to investigate whether atopy in young adults predicted asthma 20 years later and to quantify the contemporaneous relationship of atopy and asthma as adults age. METHODS: Participants of the European Community Respiratory Health Survey (ECRHS) in Melbourne aged 20-44 years were followed for 20 years and completed questionnaires, skin prick tests (SPT) and allergen specific immunoglobulin E measurement at a baseline and two subsequent surveys...

BACKGROUND: Patients with asthma present structural and inflammatory alterations that are believed to play a role in disease severity. However, airway remodeling and inflammation have not been extensively investigated in relation to both symptom control and airflow obstruction in severe asthmatics. We aimed to investigate several inflammatory and structural pathological features in bronchial biopsies of severe asthmatics that could be related to symptom control and airflow obstruction after standardized treatment...

Validated protein biomarkers are needed for assessing health trajectories, predicting and subclassifying disease, and optimizing diagnostic and therapeutic clinical decision-making. The sensitivity, specificity, accuracy, and precision of single or combinations of protein biomarkers may be altered by differences in physiological states limiting the ability to translate research results to clinically useful diagnostic tests. Aptamer based affinity assays were used to test whether low abundant serum proteins differed based on age, sex, and fat mass in a healthy population of 94 males and 102 females from the MECHE cohort...

Symbiont shift is rare in obligate mutualisms because both the partners are reciprocally dependent on and specialized to each other. In the obligate accommodation-transportation mutualism between walking corals and sipunculans, however, an unusual saltatory symbiont shift was discovered. In shallow waters of southern Japan, an undescribed hermit crab species was found living in corallums of solitary scleractinian corals of the genera Heterocyathus and Heteropsammia, replacing the usual sipunculan symbiont. We described the hermit crab as a new species Diogenes heteropsammicola (Decapoda, Anomura, Diogenidae), and explored its association with the walking corals...

Cutaneous leishmaniasis (CL) is the most common clinical form of American tegumentary leishmaniasis caused by Leishmania (Viannia) braziliensis. CL is associated with a strong Th1 immune response. This exacerbated inflammatory response is correlated with severity of disease and delays the healing time of the ulcer. The fourth-generation immucillin derivative (DI4G), a potent inhibitor of purine nucleoside phosphorylase, has been proposed as a promising agent in the treatment of diseases associated with T cell activation...

The recent detection of tetrodotoxins (TTXs) in puffer fish and shellfish in Europe highlights the necessity to monitor the levels of TTXs in seafood by rapid, specific, sensitive and reliable methods in order to protect human consumers. A previous immunoassay for TTX detection in puffer fish, based on the use of self-assembled monolayers (SAMs) for the immobilization of TTX on maleimide plates (mELISA), has been modified and adapted to the analysis of oyster and mussel samples. Changing dithiol for cysteamine-based SAMs enabled reductions in the assay time and cost, while maintaining the sensitivity of the assay...

The recent detection of tetrodotoxins (TTXs) in European fish and shellfish has emphasized the urgent need to develop specific, selective, rapid and easy-to-use methods for their detection to assess the potential risk posed to human health. For this purpose, a dithiol self-assembled monolayer (SAM)-based immunoassay previously performed on maleimide plates (mELISA) has been adapted to gold electrode arrays for the development of an electrochemical immunosensor for TTX. The electrochemical SAM-based immunosensor designed herein, provided an oriented, stable and spaced sensing platform for the determination of TTX, attaining a limit of detection of 2...

Melanoma is a highly invasive and metastatic cancer with high mortality rates and chemoresistance. Around 50% of melanomas are driven by activating mutations in BRAF that has led to the development of potent anti-BRAF inhibitors. However resistance to anti-BRAF therapy usually develops within a few months and consequently there is a need to identify alternative therapies that will bypass BRAF inhibitor resistance. The curcumin analogue DM-1 (sodium 4-[5-(4-hydroxy-3-methoxy-phenyl)-3-oxo-penta-1,4-dienyl]-2-methoxy-phenolate) has substantial anti-tumor activity in melanoma, but its mechanism of action remains unclear...

Medicines receiving a conditional marketing authorization through Medicines Adaptive Pathways to Patients (MAPPs) will be a challenge for payers. The "introduction" of MAPPs is already seen by the European Medicines Agency (EMA) as a fait accompli, with payers not consulted or involved. However, once medicines are approved through MAPPs, they will be evaluated for funding by payers through different activities. These include Health Technology Assessment (HTA) with often immature clinical data and high uncertainty, financial considerations, and negotiations through different types of agreements, which can require monitoring post launch...

Regenerative endodontic procedures (REPs) have been shown to promote the resolution of signs and symptoms of disease and increase survival compared with traditional treatment procedures. However, there is still variable predictability of continued root development and evidence that the tissues formed do not recapitulate the native pulp-dentin complex. There is growing evidence that the apical papilla is capable of surviving prolonged endodontic infection and apical periodontitis and that it represents a rich source of undifferentiated mesenchymal stem cells in REPs...

The 2-(quinolin-4-yloxy)acetamides (QOAs) have been reported as promising molecules for tuberculosis treatment. Recent studies demonstrated its potent antimycobacterial activity, as well as its biological stability and synergism with rifampicin. The identification of the molecular target is an essential step towards the development of a novel drug candidate. Here we report the target identification of the QOAs. We found that these compounds are active against isoniazid, rifampicin, ethambutol, streptomycin and ethionamide resistant clinical isolates from M...

Tetradenia riparia (Lamiaceae) is native to Central Africa popularly known as myrrh, used in folk medicine to treat various diseases like malaria, gastroenteritis, and tropical skin disease. This research was to evaluate the antioxidant and antibacterial activities of the crude extract (CE) and fractions (FR) of the T. riparia by classical chromatography. The CE of T. riparia leaves was submitted to column chromatographic fractionation to obtain four fractions of the interest, which were identified by nuclear magnetic resonance and gas chromatograph coupled to mass spectrum: FR-I (abieta-7,9(11)-dien-13-β-ol), FR-II (Ibozol), FR-III (8 (14), 15-sandaracopimaradiene-2α, 18-diol and 8 (14), 15-sandaracopimaradiene-7α, 18-diol), and FR-IV (Astragalin, Boronolide and Luteolin)...
