Dynamics of seasonal microbial community compositions in algae cultivation ponds are complex. However, there is very limited knowledge on bacterial communities that may play significant roles with algae in the bioconversion of manure nutrients to animal feed. In this study, water samples were collected during winter, spring, summer, and fall from the dairy lagoon effluent (DLE), high rate algae ponds (HRAP) that were fed with diluted DLE, and municipal waste water treatment plant (WWTP) effluent which was included as a comparison system for the analysis of total bacteria, Cyanobacteria, and microalgae communities using MiSeq Illumina sequencing targeting the 16S V4 rDNA region...

Morphea, dermatomyositis (DM), and discoid lupus erythematosus (DLE) are autoimmune collagen vascular diseases that can present at any age. In all three of these diseases, the tenants of diagnosis and treatment are largely the same in both children and adults, with a few notable differences. Children with morphea are more likely to present with the linear subtype and have a higher incidence of extracutaneous manifestations. Children often need early aggressive systemic treatment to try to prevent long-term sequelae of morphea...

Manumycin A is a natural antibiotic isolated from Streptomyces parvulus with broad range of biological activities including antineoplastic activity in several in vitro and in vivo cancer models. Immodin [dialyzable leukocyte extract (DLE)] is a dialysate released from disintegrated blood leukocytes of healthy donors which exerts immunonormalizing effects on cell-mediated immune responses. The aim of the present study was to explore the antitumor potential of the combination of manumycin A and Immodin in an experimental breast cancer model...

Reconstitution of the hematopoietic system during immune responses and immunological and neoplastic diseases or upon transplantation depends on the emergent differentiation of hematopoietic stem/progenitor cells within the bone marrow. Although in the last decade the use of dialyzable leukocyte extracts (DLE) as supportive therapy in both infectious and malignant settings has increased, its activity on the earliest stages of human hematopoietic development remains poorly understood. Here, we have examined the ability of DLE to promote replenishment of functional lymphoid lineages from CD34(+) cells...

One major challenge in the field of nanotherapeutics is to increase the selective delivery of cargo to targeted cells. Using polylactic-co-glycolic acid (PLGA), we recently highlighted the importance of polymer composition in the biological fate of the nanodrug delivery systems. However, the route of internalization of polymeric nanoparticles (NPs) is another key component to consider in the elaboration of modern and targeted devices. For that purpose, herein, we effectively synthesized and characterized glutathione-functionalized PLGA-nanoparticles (GSH-NPs) loaded with curcumin (GSH-NPs-Cur), using thiol-maleimide click reaction and determined their physicochemical properties...

Cutaneous Squamous cell carcinoma (SCC) is the second most common form of non-melanotic skin cancer after basal cell carcinoma (BCC). It is a well-known complication of discoid lupus erythematosus (DLE) and usually favours the depigmented lesions located over sun-exposed areas. The clinical course of this complication may be aggressive, with a high risk of mortality. Literature describes numerous case reports of SCC complicating the lesions of DLE but mutilating SCC is rarely mentioned. Here in, we report a rare case of mutilating squamous cell carcinoma arising in an early (two years duration) lesion of DLE...

A 50-year-old African American male with Discoid Lupus Erythematosus (DLE) presented to the dermatology clinic for a rapidly enlarging left cheek mass. The mass failed to resolve with conservative measures. A biopsy revealed poorly differentiated Squamous Cell Carcinoma (SCC). He was referred to Head and Neck Surgery and successfully underwent a resection with free flap reconstruction. Postoperatively he did well. Squamous cell skin carcinomas arising from lesions of Discoid Lupus are rare and aggressive tumors with greater likelihood of metastases...

Cellular lysates from PPD(+) donors have been reported to transfer tuberculin reactivity to naïve recipients, but not diphtheria reactivity, and vice versa. A historically controversial topic, the terms "transfer factor" and "DLE" were used to characterize the reactivity-transferring properties of lysates. Intrigued by these reported phenomena, we found that the cellular extract derived from antigen-specific memory CD8(+) T cells induces IL-6 from antigen-matched APCs. This ultimately elicits IL-17 from bystander memory CD8(+) T cells...

BACKGROUND: The dichotic digits test is one of the most widely used assessment tools for central auditory processing disorder. However, questions remain concerning the impact of cognitive factors on test results. PURPOSE: To develop the Dichotic Digits difference Test (DDdT), an assessment tool that could differentiate children with cognitive deficits from children with genuine dichotic deficits based on differential test results. The DDdT consists of four subtests: dichotic free recall (FR), dichotic directed left ear (DLE), dichotic directed right ear (DRE), and diotic...

Overlap syndromes are known to occur with connective-tissue diseases (CTDs). Rarely, the overlap occurs at the same tissue site. We report the case of a patient with clinical and histopathologic findings consistent with the presence of discoid lupus erythematosus (DLE) and localized scleroderma within the same lesions. Based on our case and other reported cases in the literature, the following features are common in patients with an overlap of lupus erythematosus (LE) and localized scleroderma: predilection for young women, photodistributed lesions, DLE, linear morphology clinically, and positivity along the dermoepidermal junction on direct immunofluorescence...

Chronic lip discoid lupus erythematosus (DLE) is a potentially malignant disorder that can develop into lip squamous cell carcinoma (LSCC). Podoplanin is a specific marker for lymphatic endothelial cells and plays a role in cancer progression. The objective of this study was to determine the immunoexpression of podoplanin in samples of patients with DLE and its correlation with the risk of progression to LSCC. In a retrospective study, podoplanin expression was determined using immunohistochemistry in samples from 52 patients with DLE, including 44 patients with untransformed DLE and 8 patients with malignant transformed DLE...

Discoid lupus erythematosus (DLE) is a chronic cutaneous disease characterized by inflammatory plaques that, in the absence of prompt diagnosis and treatment, may lead to disfiguring scarring and skin atrophy. However, there is limited evidence for which treatments are most effective. Currently, no medications have been approved specifically for the treatment of DLE. Many of the drugs described in the literature were developed for use in other immune disorders. This review will summarize current therapeutic options for DLE and their supporting evidence with discussion of prevention, topical measures, physical modalities, and systemic therapies, including newer potential therapies...

The aim of the present study was to identify preoperative clinical predictors for difficult laryngeal exposure (DLE) and to define a simple grading system for laryngeal exposure. This is a prospective descriptive study carried out in a tertiary teaching hospital in South India. Patients above 18 years undergoing microlaryngoscopy had presurgical evaluation of 11 physical parameters. Grading of Modified Cormack-Lehane Score (MCLS) and rigid laryngoscopy were done during procedure. On logistic regression analysis, with a 95 % confidence interval (CI) MCLS was found to be a statistically significant predictor (odds ratio 12)...

Lupus mastitis is an uncommon presentation of lupus erythematosus profundus (LE profundus), characterized by inflammation of the subcutaneous fat. LE profundus occurring as initial manifestation of LE is rare. We report a case where the patient presented with lupus mastitis and years later, she developed disseminated discoid LE (DLE) and polyarteritis nodosa (PAN). PAN and DLE are connective tissue diseases with different etiologies, clinical, immunological, and histopathological features. One connective tissue disease evolving into another is rare, and the reasons remain unexplained...
