Assessing Diagnosis of Infections: A Study on Species Prevalence and Antifungal Resistance in Northern Morocco.

The incidence of infections has increased in the last decade, posing a serious threat to public health. Appropriately facing this challenge requires precise epidemiological data on species and antimicrobial resistance incidence, but many countries lack appropriate surveillance programs. This study aims to bridge this gap for Morocco by identifying and phenotyping a year-long collection of clinical isolates (n = 93) from four clinics in Tetouan.

Genomics of the expanding pine pathogen reveals patterns of ongoing genetic admixture.

Unlabelled: is the causal agent for brown spot needle blight that affects pine trees across the northern hemisphere. Based on marker genes and microsatellite data, two distinct lineages have been identified that were introduced into Europe on two separate occasions. Despite their overall distinct geographic distribution, they have been found to coexist in regions of northern Spain and France.

Origin of fungal hybrids with pathogenic potential from warm seawater environments.

Hybridisation is a common event in yeasts often leading to genomic variability and adaptation. The yeast Candida orthopsilosis is a human-associated opportunistic pathogen belonging to the Candida parapsilosis species complex. Most C.

Evolution of loss of heterozygosity patterns in hybrid genomes of Candida yeast pathogens.

Background: Hybrids are chimeric organisms with highly plastic heterozygous genomes that may confer unique traits enabling the adaptation to new environments. However, most evolutionary theory frameworks predict that the high levels of genetic heterozygosity present in hybrids from divergent parents are likely to result in numerous deleterious epistatic interactions. Under this scenario, selection is expected to favor recombination events resulting in loss of heterozygosity (LOH) affecting genes involved in such negative interactions.

Association Between Insulin-Like Growth Factor-1 and Social Cognition in Huntington's Disease.

Background: Insulin-like growth factor 1 (IGF-1) seems to be involved in the neural circuits associated with social cognition and brain structure.

Objectives: To investigate the association of IGF-1 levels with social cognition and brain structure in Huntington's disease (HD).

Methods: We evaluated social cognition using the Ekman test in 22 HD patients and 19 matched controls.

[Effectiveness on adherence to biological drugs and experience of a pharmaceutical intervention based on CMO model in patients with rheumatic disease (AdhER-2 study)].

Background: We aimed to assess the effectiveness on adherence to treatment with biologic disease modifying anti-rheumatic drugs (b-DMARD) and experience with providers of healthcare of a CMO pharmaceutical intervention care model in subjects with rheu-matoid arthritis, psoriatic arthritis, and ankylosing spondylitis stratified according to their needs.

Method: Prospective, single-centre randomized controlled study. The study period was eleven months.

Narrow mutational signatures drive acquisition of multidrug resistance in the fungal pathogen Candida glabrata.

Fungal infections are a growing medical concern, in part due to increased resistance to one or multiple antifungal drugs. However, the evolutionary processes underpinning the acquisition of antifungal drug resistance are poorly understood. Here, we used experimental microevolution to study the adaptation of the yeast pathogen Candida glabrata to fluconazole and anidulafungin, two widely used antifungal drugs with different modes of action.

[Adherence to biological therapies in patients with rheumatoid arthritis, psoriatic arthritis and ankylosing spondylitis. (Study ADhER-1)].

Background: To quantify adherence to biological disease-modifying anti-rheumatic drugs (DMARD) and to determine the factors that can predict adherence in patients with rheumatoid arthritis, psoriatic arthritis and ankylosing spondylitis in daily clinical practice.

Methods: An observational, descriptive, cross-sectional and single-center study was carried out. Patients with rheumatoid arthritis, ankylosing spondylitis and psoriatic arthritis who were in treatment with subcutaneous biological DMARD were included.

Identification and structural characterization of the factors involved in vitellogenesis and its regulation in the African Osteoglossiforme of aquacultural interest Heterotis niloticus (Cuvier, 1829).

The African bonytongue (Heterotis niloticus) is an excellent candidate for fish farming because it has outstanding biological characteristics and zootechnical performances. However, the absence of sexual dimorphism does not favor its reproduction in captivity or the understanding of its reproductive behavior. Moreover, no molecular data related to its reproduction is yet available.

Battle of Thermopylae: 300 Spartans (natural killer cells plus obinutuzumab) versus the immortal warriors (chronic lymphocytic leukemia cells) of Xerxes' army.

Aim: To analyze the effects of subcutaneous or intravenous rituximab + lymphokine-activated killer cells, obinutuzumab or ibrutinib on natural killer (NK) cell levels in chronic lymphocytic leukemia and follicular lymphoma patients.

Patients & Methods: The distribution of peripheral blood NK cells of 31 patients was analyzed by flow cytometry.

Results: We detected a decrease of NK cells in peripheral blood below normal range after obinutuzumab treatment.

The phosphatase Ptc6 is involved in virulence and MAPK signalling in Fusarium oxysporum.

Mitogen-activated kinase (MAPK) signalling pathways are involved in several important processes related to the development and virulence of Fusarium oxysporum. Reversible phosphorylation of the protein members of these pathways is a major regulator of essential biological processes. Among the phosphatases involved in dephosphorylation of MAPKs, type 2C protein phosphatases (PP2Cs) play important roles regulating many developmental strategies and stress responses in yeasts.

Plasma vitellogenin levels during the annual reproductive cycle of the female rainbow trout (Oncorhynchus mykiss): establishment and validation of an ELISA.

Rainbow trout, Oncorhynchus mykiss, vitellogenin (Vtg) was purified from plasma of E2-treated male by direct anion exchange chromatography and some of its biochemical characteristics were studied. Our results demonstrated that, under SDS-PAGE conditions, rainbow trout Vtg was composed of two molecular forms of 390 and 176 kDa representing, respectively, the dimeric form and the monomeric from of the molecule. The purified Vtg was used to raise a polyclonal antibody for Vtg (anti-Vtg).

Identification of vitellogenin receptors in the ovary of a teleost fish, the Mediterranean sea bass (Dicentrarchus labrax).

The characterization of vitellogenin (VTG) receptors in ovarian membranes from vitellogenic female sea bass (Dicentrarchus labrax) is described. Incubation of membrane proteins with radiolabeled VTG (125I-VTG) after SDS-electrophoresis showed specific binding of 125I-VTG to a protein band of 100 kDa. Filter binding assays showed that binding of 125I-VTG to membrane receptors was saturable with increasing amounts of 125I-VTG.

Vitellogenin receptors during vitellogenesis in the rainbow trout Oncorhynchus mykiss.

Rainbow trout vitellogenin receptors have been characterized by ligand blotting and Scatchard analysis. Their evolution has been studied over a reproductive cycle in a broodstock of 2-year-old females. The receptors were prepared from ovarian membrane homogenates and were solubilized using n-octyl-beta-D-glucopyranoside.

Development of an enzyme-linked immunosorbent assay for goldfish gonadotropin.

An enzyme-linked immunosorbent assay (ELISA) for goldfish gonadotropin (GTH) was developed with the intent of devising a simple, reliable and nonradioisotopic assay for the measurement of GTH in goldfish biological samples. In this assay, soluble GTH of the standards or samples competes with carp GTH (cGTH) immobilized on a solid support (96-well microplate) for the fixation on antibodies to the beta-subunit of carp gonadotropin. The immobilized antigen-antibody complexes are then revealed by the peroxidase-antiperoxidase (PAP) technique.

Immunohistochemical investigation of the pituitary of the sturgeon (Acipenser baeri, Chondrostei).

An immunohistochemical study of the sturgeon (Acipenser baeri) pituitary was undertaken using antisera directed against hormones from various classes of vertebrates, including the only pituitary hormone available from sturgeon, gonadotrophin. A positive reaction was obtained after application of antisera towards the following hormones 1-24 synthetic ACTH (1-24 ACTH), melanophore stimulating hormone (MSH), ovine prolactin (oPRL), ovine growth hormone (oGH), salmon growth hormone (sGH), carp gonadotrophin (cGTH) and its beta subunit (βcGTH), sturgeon gonadotrophin (aciGTH), carp thyrotrophin (cTSH) and β subunit of the human thyrotrophin (βhTSH). The results demonstrate that, in general, the sturgeon pituitary resembles that of teleosts as regards the distribution of the different cell types: ACTH and PRL cells in the rostral pars distalis, GTH, TSH and GH cells in the proximal pars distalis and MSH and PAS-cells in pars intermedia.

A reinvestigation of the Gn-RH (gonadotrophin-releasing hormone) systems in the goldfish brain using antibodies to salmon Gn-RH.

The organization of Gn-RH systems in the brain of teleosts has been investigated previously by immunohistochemistry using antibodies against the mammalian decapeptide which differs from the teleostean factor. Here, we report the distribution of immunoreactive Gn-RH in the brain of goldfish using antibodies against synthetic teleost peptide. Immunoreactive structures are found along a column extending from the rostral olfactory bulbs to the pituitary stalk.
