Culturable and unculturable potential heterotrophic microbiological threats to the oldest pyramids of the Memphis necropolis, Egypt.

A large percentage of the world's tangible cultural heritage is made from stone; thus, it deteriorates due to physical, chemical, and/or biological factors. The current study explored the microbial community inhabiting two prehistoric sites with high cultural value in the Memphis necropolis of Egypt (Djoser and Lahun Pyramids) using amplicon-based metabarcoding and culture-dependent isolation methods. Samples were examined by epifluorescent microscopy for biological signs before environmental DNA extraction and in vitro cultivation. The metabarcoding analysis identified 644 bacterial species (452 genera) using the 16S rRNA and 204 fungal species (146 genera) using ITS. In comparison with the isolation approach, an additional 28 bacterial species (13 genera) and 34 fungal species (20 genera) were identified. A total of 19 bacterial and 16 fungal species were exclusively culture-dependent, while 92 bacterial and 122 fungal species were culture-independent. The most abundant stone-inhabiting bacteria in the current study were Blastococcus aggregatus, Blastococcus saxobsidens, and Blastococcus sp., among others. The most abundant rock-inhabiting fungi were Knufia karalitana and Pseudotaeniolina globosa, besides abundant unknown Sporormiaceae species. Based on previous reports, microorganisms associated with biodeterioration were detected on color-altered sites at both pyramids. These microorganisms are potentially dangerous as physical and chemical deterioration factors and require proper conservation plans from a microbiological perspective.

Comparing Preferred and Actual Clinical Learning Environments and Perceptions of First-Year Nursing Students in Long-Term Care: A Cross-Sectional Study.

The clinical learning environment, which includes the culture of clinical units, the mentoring process, and the different health organizations, influences the learning process of nursing students. However, scarce literature has been published on the impact of the clinical learning environment on first-year nursing students in long-term care. We aimed to assess first-year nursing students 'preferred' and 'actual' clinical learning environments when conducting their first placements in nursing homes within an innovative placement model that comprised the active participation of academic mentors. The validated Spanish version of the Clinical Learning Environment Inventory (CLEI) instrument was used in our study, and 99 first-year nursing students participated. The highest mean scores for the CLEI-Actual were found for the Satisfaction (22.7) and Involvement scales (19.09). The lowest mean scores were found for the Personalization (17) and Individualization (17.27) scales. The multiple correlation (R) between the Satisfaction and the other CLEI scales was 0.61 (p > 0.001), which means that in this study the association between student satisfaction and their perception of the clinical learning environment was strong. First-year students conducting their first clinical placements in nursing homes can have a positive learning experience considering a well-designed and organized pedagogical strategy, including constant support and feedback from academic and clinical mentors.

aroF and cm2: potential molecular markers for the detection of stone-inhabiting Actinobacteria on cultural heritage sites.

Tangible archeological sites and stone monuments are naturally decayed and deteriorated over time, providing substances that can sustain life, although they provide a complicated ecosystem characterized by low nutrition and desiccation. Stone-inhabiting bacteria (SIB) and especially members of the phylum Actinobacteria dominate such environments, particularly the members of the family Geodermatophilaceae. We used the published data of two confirmed SIB species to mine their genomes for specific molecular markers to rapidly survey the presence of SIB in cultural heritage material prior to further analysis. The search focused on the mycosporine-like amino acids (MAAs) synthesis pathway. MAAs are intracellular compounds biosynthesized by the shikimic acid pathway to synthesize aromatic amino acids and were found related to abiotic resistance features in microorganisms. Based on genome mining, the DAHP II (aroF) and a homolog of the Chorismate mutase gene (cm2) were found mostly in Actinobacteria and few other species. After calibration on five stone-inhabiting Actinobacteria (SIAb) species using conventional PCR, newly designed primers were successfully applied to environmental DNA extracted from two Egyptian pyramidal sites using a qPCR approach. This is the first report of aroF and cm2 as qPCR markers to detect SIAb from cultural heritage material prior to proceeding with further analysis (e.g., metagenomics and meta-barcoding analyses).

Efficacy of Posterior Tibial Nerve Stimulation in the Treatment of Fecal Incontinence: A Systematic Review.

Fecal incontinence is a condition that carries high social stigmatization and a determining factor in the quality of life of the person who suffers from it. Its etiology is multifactorial and treatment includes surgical and conservative measures, including stimulation of the posterior tibial nerve. The aim of this review is to determine whether posterior tibial nerve stimulation (PTNS) is more effective than other treatments in reducing episodes of fecal incontinence in adults. A systematic review of randomized clinical trials that analyzed different approaches and comparisons with other treatments in adults without neurological or metabolic diseases was carried out, analyzing, fundamentally, the reduction of episodes of fecal incontinence. In general, a reduction in fecal incontinence episodes is observed in the experimental groups compared with the control groups, although these differences are not significant in most studies. The results regarding the effectiveness of PTNS in reducing episodes of fecal incontinence compared to other treatments are not entirely conclusive, although benefits are observed regarding the stimulation of sacral roots. More well-designed studies with a long-term follow-up of the results are needed so that the recommendation of this treatment can be generalized.

Beneficial Effects of Fructooligosaccharides Esterified with Lauric Acid in a Metabolic Syndrome Model Induced by a High-Fat and High-Carbohydrate Diet in Wistar Rats.

Metabolic syndrome (MS) is a group of abnormalities in which obesity, insulin resistance (IR), oxidative stress, and dyslipidemia stand out. This pathology predisposes to the development of cardiovascular diseases and diabetes. The ingestion of linear fructooligosaccharides (FOS) such as inulin reduces conditions such as hyperinsulinemia, increased body fat, and triglyceridemia. When FOS are esterified with fatty acids, they present emulsifying and surfactant properties; however, there are no reports of their function at the biological level. The purpose of this investigation was to evaluate the effect of Agave tequilana Weber's FOS (AtW-FOS) and FOS esterified with lauric acid (FOS-LA) in MS markers in a rat model induced by a HFHC diet. Supplementation with AtW-FOS and FOS-LA decreased IR, improved glucose tolerance, reduced liver weight (19%), plasma triglycerides (24%), and blood pressure (16%) when compared with the untreated MS group. In conclusion, the ingestion of AtW-FOS and FOS-LA has beneficial effects in the prevention of MS alterations, showing a high potential for their application in functional foods.

Beneficial effects of an algal oil rich in ω-3 polyunsaturated fatty acids on locomotor function and D2 dopamine receptor in haloperidol-induced parkinsonism.

INTRODUCTION: Parkinson's disease (PD) is a chronic neurological disorder whose pathogenesis involves the loss of dopaminergic neurons and dopamine terminals, formation of Lewy bodies, and microgliosis. Its treatment includes dopamine-based drugs with limited results and adverse effects. Additionally, some neuroleptic drugs used for mental disorders produce side effects referred to as parkinsonism. Dietary interventions with ω-3 polyunsaturated fatty acids (ω-3 PUFA) have attracted attention since they play a key role in most of the processes associated with PD etiology. OBJECTIVE: The purpose of our work was to investigate the effects of an ω-3 PUFA rich algal oil on locomotive alterations induced by haloperidol and D2 receptor protein and gene expression in Wistar rats. METHODOLOGY: Pre- and co-supplementation of algal oil (300 mg of ω-3 FA/kg/day for six weeks) and haloperidol (1.5 mg/kg/day for two weeks) were evaluated. RESULTS: Haloperidol provoked locomotive alterations in the Open Field Test and a 43% diminution in D2 receptor in brain membranes; in pre-supplemented rats a 93% increase in D2 receptor protein expression and a partial maintenance of locomotory performance were observed, while in co-supplemented rats D2 receptor protein expression was maintained as in control rats, although locomotive behavior was found diminished as in haloperidol rats. CONCLUSIONS: These results confirm the beneficial effects of ω-3 PUFA over locomotory alterations and as neuroprotective and neurorestorative compounds and demonstrates a stimulatory action on D2 receptor presence, as a mechanism by which these fatty acids participate in brain health.

Inhibition of Stearoyl-CoA Desaturase by Sterculic Oil Reduces Proliferation and Induces Apoptosis in Prostate Cancer Cell Lines.

Prostate cancer (PCa) is a common type of cancer affecting male population. PCa treatments have side effects and are temporarily effective, so new therapeutic options are being investigated. Due to the high demand of energy for cell proliferation, an increase in the expression and activity of lipogenic enzymes such as the stearoyl-CoA desaturase (SCD) have been observed in PCa. Sterculic acid, contained in the seed's oil of Malvales, is a natural inhibitor of SCD. The objective of our investigation was to evaluate the effects of sterculic oil (SO) from Sterculia apetala seeds on proliferation, cell cycle and apoptosis in prostate cancer cells. SO was administered to PC3 and LNCaP cells, and to prostate normal cells; cell viability, cell cycle, apoptosis, SCD gene and protein expression and enzymatic activity were analyzed. SO administration (4 mM sterculic acid) diminished cell viability in LNCaP and PC3 cells, arrested cell cycle in G2 and promoted apoptosis. SO diminished SCD enzymatic activity with no effects on gene nor protein expression. Our results suggest that SO might offer benefits as an adjuvant in hormonal and chemotherapy prostate cancer treatments. This is the first study to analyze the effect of SO on cancer cells.

Production and Characterization of Cross-Linked Aggregates of Geobacillus thermoleovorans CCR11 Thermoalkaliphilic Recombinant Lipase.

Immobilization of enzymes has many advantages for their application in biotechnological processes. In particular, the cross-linked enzyme aggregates (CLEAs) allow the production of solid biocatalysts with a high enzymatic loading and the advantage of obtaining derivatives with high stability at low cost. The purpose of this study was to produce cross-linked enzymatic aggregates (CLEAs) of LipMatCCR11, a 43 kDa recombinant solvent-tolerant thermoalkaliphilic lipase from Geobacillus thermoleovorans CCR11. LipMatCCR11-CLEAs were prepared using (NH4)2SO4 (40% w/v) as precipitant agent and glutaraldehyde (40 mM) as cross-linker, at pH 9, 20 °C. A U10(56) uniform design was used to optimize CLEA production, varying protein concentration, ammonium sulfate %, pH, glutaraldehyde concentration, temperature, and incubation time. The synthesized CLEAs were also analyzed using scanning electron microscopy (SEM) that showed individual particles of <1 µm grouped to form a superstructure. The cross-linked aggregates showed a maximum mass activity of 7750 U/g at 40 °C and pH 8 and retained more than 20% activity at 100 °C. Greater thermostability, resistance to alkaline conditions and the presence of organic solvents, and better durability during storage were observed for LipMatCCR11-CLEAs in comparison with the soluble enzyme. LipMatCCR11-CLEAs presented good reusability by conserving 40% of their initial activity after 9 cycles of reuse.

Expression of a Cutinase of Moniliophthora roreri with Polyester and PET-Plastic Residues Degradation Activity.

Cutinases are enzymes produced by phytopathogenic fungi like Moniliophthora roreri. The three genome-located cutinase genes of M. roreri were amplified from cDNA of fungi growing in different induction culture media for cutinase production. The mrcut1 gene was expressed in the presence of a cacao cuticle, while the mrcut2 and mrcut3 genes were expressed when an apple cuticle was used as the inducer. The sequences of all genes were obtained and analyzed by bioinformatics tools to determine the presence of signal peptides, introns, glycosylation, and regulatory sequences. Also, the theoretical molecular weight and pI were obtained and experimentally confirmed. Finally, cutinase 1 from M. roreri (MRCUT1) was selected for heterologous expression in Escherichia coli. Successful overexpression of MRCUT1 was observed with the highest enzyme activity of 34,036 U/mg under the assay conditions at 40°C and pH 8. Furthermore, the degradation of different synthetic polyesters was evaluated; after 21 days, 59% of polyethylene succinate (PES), 43% of polycaprolactone (PCL), and 31% of polyethylene terephthalate (PET) from plastic residues were degraded. IMPORTANCE Plastic pollution is exponentially increasing; even the G20 has recognized an urgent need to implement actions to reduce it. In recent years, searching for enzymes that can degrade plastics, especially those based on polyesters such as PET, has been increasing as they can be a green alternative to the actual plastic degradation process. A promising option in recent years refers to biological tools such as enzymes involved in stages of partial and even total degradation of some plastics. In this context, the MRCUT1 enzyme can degrade polyesters contained in plastic residues in a short time. Besides, there is limited knowledge about the biochemical properties of cutinases from M. roreri. Commonly, fungal enzymes are expressed as inclusion bodies in E. coli with reduced activity. Interestingly, the successful expression of one cutinase of M. roreri in E. coli with enhanced activity is described.

Diversity of Bacterioplankton and Bacteriobenthos from the Veracruz Reef System, Southwestern Gulf of Mexico.

Bacterial diversity was explored among field samples and cultured isolates from coral reefs within the Veracruz Reef System. Bacterioplankton and bacteriobenthos were characterized by pyrosequencing 16S rRNA genes. Identified sequences belonged to the kingdom Bacteria and classified into 33 phyla. Proteobacteria (likely SAR11 clade) dominated in collective field samples, whereas Firmicutes were the most abundant taxa among cultured isolates. Bioinformatic sorting of sequences to family level revealed 223 bacterial families. Pseudomonadaceae, Exiguobacteraceae and Bacillaceae were dominant among cultured isolates. Vibrionaceae, Alteromonadaceae, and Flavobacteriaceae dominated in reef-associated sediments, whereas Rickettsiaceae and Synechoccaceae were more highly represented in the water column. Bacterial communities from sediments were more diverse than from the water column. This study reveals cryptic bacterial diversity among microenvironmental components of marine microbial reef communities subject to differential influence of anthropogenic stressors. Such investigations are critical for constructing scenarios of environmentally induced shifts in bacterial biodiversity and species composition.

A New Extremotolerant Ecotype of the Fungus Pseudotaeniolina globosa Isolated from Djoser Pyramid, Memphis Necropolis, Egypt.

Most of the rock-inhabiting fungi are meristematic and melanized microorganisms often associated with monument biodeterioration. In previous microbial profiling of the Egyptian Djoser pyramid, a Pseudotaeniolina globosa isolate was found. The current study aimed to characterize the P. globosa isolated from the Djoser pyramid compared with an Italian isolate at morphological, physiological, and molecular levels. Experiments were carried out to test temperature, salinity, and pH preferences, as well as stress tolerance to UV radiation and high temperature, in addition to a multi-locus genotyping using ITS, nrSSU or 18S, nrLSU or 28S, BT2, and RPB2 markers. Morphological and molecular data confirmed the con-specificity of the two isolates. However, the Egyptian isolate showed a wider range of growth at different environmental conditions being much more tolerant to a wider range of temperature (4-37 °C) and pH values (3.0-9.0 pH) than the Italian (10-30 °C, 4.0-6.0 pH), and more tolerant to extreme salinity levels (5 M NaCl), compared to the lowest in the Italian isolate (0.2 M NaCl). Besides, the Egyptian isolate was more tolerant to high temperature than the Italian isolate since it was able to survive after exposure to up to 85 °C for 5 min, and was not affected for up to 9 h of UV exposure, while the Italian one could not regrow after the same treatments. The Pseudotaeniolina globosa species was attributed to the family Teratosphaeriaceae of the order Capnodiales, class Dothideomycetes. Our results demonstrated that the Egyptian isolate could be considered an ecotype well adapted to harsh and extreme environments. Its potential bio-deteriorating effect on such an important cultural heritage requires special attention to design and conservation plans and solutions to limit its presence and extension in the studied pyramid and surrounding archaeological sites.

XEN 63 gel stent device in glaucoma surgery: A 5-years follow-up prospective study.

PURPOSE: To evaluate the efficacy and safety of the XEN63 Gel Stent in patients with open-angle glaucoma (OAG). METHODS: Prospective, nonrandomized, open-label, not-controlled, and single center study conducted on OAG patients who underwent glaucoma surgery with the XEN63 gel stent. The main outcome measure was intraocular pressure (IOP). Secondary end-points were number of topical ocular hypotensive drugs, percentage of patients achieving an IOP reduction ⩾20%, and treatment-related adverse events. RESULTS: Eleven eyes from 11 patients were treated with XEN 63. Mean (95% confidence interval, CI) age was 78.8 (73.7-85.9). Two eyes (18.2%) underwent XEN alone, while nine eyes (81.8%) underwent combined XEN + cataract extraction (phacoemulsification). The median (95% CI) IOP reduction was 17.7% (-13.3% to 34.9%). At the end of the study 9 (81.8%) eyes had an IOP ⩽ 18 mm Hg, six of them without treatment. Six (54.6%) eyes obtained an IOP reduction ⩾20%. Compared to baseline, there was a significant reduction in the number of ocular hypotensive drugs (p = 0.0039). There were no treatment-related serious adverse events. Early postoperative complications included diplopia (1), blood in endothelium (2), ocular hypertension (1), corneal edema (1), folds in Descemet's membrane (1), and contact between the implant and the iris (1). All the adverse events were successfully solved without sequalae. One eye required bleb needling. CONCLUSION: The XEN63 implant significantly reduced both IOP and the amount of ocular hypotensive medications while maintaining a good safety profile.

A Cost Reduced Variant of Epi-Genotyping by Sequencing for Studying DNA Methylation in Non-model Organisms.

Reference-free reduced representation bisulfite sequencing uses enzymatic digestion for reducing genome complexity and allows detection of markers to study DNA methylation of a high number of individuals in natural populations of non-model organisms. Current methods like epiGBS enquire the use of a higher number of methylated DNA oligos with a significant cost (especially for small labs and first pilot studies). In this paper, we present a modification of this epiGBS protocol that requires the use of only one hemimethylated P2 (common) adapter, which is combined with unmethylated barcoded adapters. The unmethylated cytosines of one chain of the barcoded adapter are replaced by methylated cytosines using nick translation with methylated cytosines in dNTP solution. The basic version of our technique uses only one restriction enzyme, and as a result, genomic fragments are integrated into two orientations with respect to the adapter sequences. Comparing the sequences of two chain orientations makes it possible to reconstruct the original sequence before bisulfite treatment with the help of standard software and newly developed software written in C and described here. We provide a proof of concept via data obtained from almond (Prunus dulcis). Example data and a detailed description of the complete software pipeline starting from the raw reads up until the final differentially methylated cytosines are given in Supplementary Material making this technique accessible to non-expert computer users. The adapter design showed in this paper should allow the use of a two restriction enzyme approach with minor changes in software parameters.

Comparative Survival and the Cold-Induced Gene Expression of Pathogenic and Nonpathogenic Vibrio Parahaemolyticus from Tropical Eastern Oysters during Cold Storage.

Expression of the regulatory stress rpoS gene controls the transcription of cspA genes, which are involved in survival and adaptation to low temperatures. The purpose of this study was to assess the growth kinetics of naturally occurring V. parahaemolyticus in shellstock oysters and in vitro and the cold-shock-induced expression of the rpoS and cspA gene response in vitro during postharvest refrigeration. Naturally contaminated eastern oysters (Crassostrea virginica) and pathogenic (Vp-tdh) and nonpathogenic (Vp-tlh) isolates were stored at 7 ± 1 °C for 168 h and 216 h, respectively. The regulatory stress (rpos) and cold-shock (cspA) gene expressions were determined by reverse transcription PCR. At 24 h, the (Vp-tdh) strain grew faster (p < 0.05) than the (Vp-tlh) strain in oysters (λ = 0.33, 0.39, respectively) and in vitro (λ = 0.89, 37.65, respectively), indicating a better adaptation to cold shock for the (Vp-tdh) strain in live oysters and in vitro. At 24 h, the (Vp-tdh) strain rpoS and cspA gene expressions were upregulated by 1.9 and 2.3-fold, respectively, but the (Vp-tlh) strain rpoS and cspA gene expressions were repressed and upregulated by -0.024 and 1.9-fold, respectively. The V. parahaemolyticus strains that were isolated from tropical oysters have adaptive expression changes to survive and grow at 7 °C, according to their virulence.

In vitro lead tolerance and accumulation in three Chrysanthemum cultivars for phytoremediation purposes with ornamental plants.

The use of ornamental plants for the phytoremediation of potentially toxic elements in polluted soils is an interesting task. It makes possible to combine environmental restoration, re-use of land, and the production of goods and services of economic interest. In this work, in vitro experiments using three cultivars of Chrysanthemum (Asteraceae) were carried out with 0, 300, 600, 900, and 1500 mg/kg of lead concentrations for a period of 12 weeks. The objective was to obtain data about their lead tolerance and bioaccumulation capacity in order to know their potential as phytoremediators in a densely populated Caribbean area of the Dominican Republic with a high concentration of lead in soils. The variations in biomass, root growth as well as accumulation of this element in the plants were measured. The results suggest that the three cultivars have a good potential for phytoextraction at moderate pollution levels, as they showed a good bioaccumulation of lead, which had mild effects on their biomass production and root elongation. Additional studies should be carried out to assess their effectiveness as phytoextractors under field conditions, as well as other alternative uses that could generate esthetic, environmental, and/or economic benefits for tropical areas contaminated by Pb.

Anthocyanins of Blue Corn and Tortilla Arrest Cell Cycle and Induce Apoptosis on Breast and Prostate Cancer Cells.

Background: Breast and prostate cancer are frequently diagnosed neoplasias in women and men around the world. The signaling of the androgen receptor (AR) influences the development of both tumors. Since therapies focused to block the receptor's activity have not been fully effective, and have shown side effects, therapies based on natural compounds are promissory complementary alternatives in its treatment. Objective: The aim of this study was to determine the effect of anthocyanins from blue corn in cancer cell lines. Methods: We analyzed the antiproliferative effect of anthocyanins from raw and alkali-processed (tortillas) Mixteco blue corn in breast and prostate cancer cell lines MDA-MB-453 (subtype: triple negative) and LNCaP using methyltiazlyl-tetrazolium (MTT) and flow cytometry (FCM). The combination of anthocyanins and 2-amino-N-quinolin-8-yl-benzenesulfonamide (QBS) or nocodazole also were evaluated. The anthocyanins were isolated trough column chromatography (XAD-7).Results: Our results demonstrated that anthocyanin specially the ones obtained from tortillas, decreased cell viability and arrested cell cycle in G1 phase inducing apoptosis. Cytometry analysis shows an increased effect on apoptosis of MDA-MB-453 and LNCaP cells when tortilla anthocyanins and QBS were combined. Conclusions: This is the first report that suggest that anthocyanins from blue corn have an effect in cell cycle and viability so they could serve as adjuvants for breast and prostate cancer therapies and may prompt to deepen investigations to decipher its molecular properties.

Preventive Action of Sterculic Oil on Metabolic Syndrome Development on a Fructose-Induced Rat Model.

The metabolic syndrome (MS) underlies metabolic disorders considered risk factors for the development of diabetes and cardiovascular diseases, which are major causes of morbidity and mortality in most of the world. Sterculic acid has been proposed as a potential tool for the treatment of MS since it inhibits the activity of the stearoyl-CoA desaturase-1 (SCD1), a central enzyme in lipid metabolism. We analyzed the effect of sterculic oil (SO) co-administration with 30% fructose in drinking water on the development of MS in male Wistar rats. After 8 weeks, 0.4% SO exerted a protective effect from MS development since parameters altered by fructose (blood pressure, insulin resistance, serum glucose and triglycerides, steatosis, and adiposity) were similar to those of control rats.
